You should be looking for the second tr that has the td that equals ' Color Digest ', then you need to look at either the following sibling of the first td in the tr, or the second td.

Try the following:

//tr[td='Color Digest'][2]/td/following-sibling::td[1]

or

//tr[td='Color Digest'][2]/td[2]

print(link_addres.contents[0])

It will print the context of the anchor tags

example:

 statement_title = statement.find('h2',class_='briefing-statement__title')
 statement_title_text = statement_title.a.contents[0]

If it's okay to write down just an opinion, that's mine:

I totally and absolutely disagree with the `Single return statement theory' and find it mostly speculative and even destructive regarding the code readability, logic and descriptive aspects.

That habit of having one-single-return is even poor for bare procedural programming not to mention more high-level abstractions (functional, combinatory etc.). And furthermore, I wish all the code written in that style to go through some special rewriting parser to make it have multiple return statements!

A function (if it's really a function/query according to `Query-Command separation' note - see Eiffel programming lang. for example) just MUST define as many return points as the control flow scenarios it has. It is much more clear and mathematically consistent; and it is the way to write functions (i.e. Queries)

But I would not be so militant for the mutation messages that your agent does receive - the procedure calls.

You can use this

foreach ($array as $key => $value) 
{
    if($key==1)
    {
        $new_array[]=$other_array;
    }   
    $new_array[]=$value;    
}

All the answers above are correct. In case you want to see it in action, don't forget you have Console in a browser where you can see the actual result crystal clear :

I have an HTML :

<div id="contents"></div>

Go to console (cntrl+shift+c) and use these commands to see your result clearly

document.getElementById('contents')
>>> div#contents

$('#contents')
>>> [div#contents,
 context: document,
 selector: "#contents",
 jquery: "1.10.1",
 constructor: function,
 init: function …]

As we can see, in the first case we got the tag itself (that is, strictly speaking, an HTMLDivElement object). In the latter we actually don’t have a plain object, but an array of objects. And as mentioned by other answers above, you can use the following command:

$('#contents')[0]
>>> div#contents

Solution is very simple - Run Visual Studio Application in Admin mode !

This allow you to send an object:

private List<object> ConvertArrayToList(dynamic array)

You can get the value of a registry key as follows

@echo OFF
setlocal ENABLEEXTENSIONS
set REG_NAME="HKEY_CURRENT_USER\Software\Test"
set KEY_NAME=TestVal

FOR /F "usebackq skip=2 tokens=1-3" %%A IN (`REG QUERY %REG_NAME% /v %KEY_NAME% 2^>nul`) DO (
    @echo %%A : %%C
)
pause

those who wonder how to add reg keys, here is a way.

REGEDIT4

; @ECHO OFF
; CLS
; REGEDIT.EXE /S "%~f0"
; EXIT

[HKEY_CURRENT_USER\Software\Test]
"TestVal"="Succeeded"

There is a limit, but you can split your values into separate blocks of in()

Select * 
From table 
Where Col IN (123,123,222,....)
or Col IN (456,878,888,....)

Assuming a simple case, where your field is public:

List list; // from your method
for(Object x : list) {
    Class<?> clazz = x.getClass();
    Field field = clazz.getField("fieldName"); //Note, this can throw an exception if the field doesn't exist.
    Object fieldValue = field.get(x);
}

But this is pretty ugly, and I left out all of the try-catches, and makes a number of assumptions (public field, reflection available, nice security manager).

If you can change your method to return a List<Foo>, this becomes very easy because the iterator then can give you type information:

List<Foo> list; //From your method
for(Foo foo:list) {
    Object fieldValue = foo.fieldName;
}

Or if you're consuming a Java 1.4 interface where generics aren't available, but you know the type of the objects that should be in the list...

List list;
for(Object x: list) {
   if( x instanceof Foo) {
      Object fieldValue = ((Foo)x).fieldName;
   }
}

No reflection needed :)

You can simply use linq

Directory.EnumerateFiles(LoanFolder).Select(file => Path.GetFileName(file));

Note: EnumeratesFiles is more efficient compared to Directory.GetFiles as you can start enumerating the collection of names before the whole collection is returned.

The simplest way I've found to do this in Windows is with WinRAR:

1. Right-click on the file and choose "Open with WinRAR" from the context menu.
2. Navigate to the file to be edited and double-click on it to open it in the default editor.
3. After making the changes, save and exit the editor.
4. A dialogue will then appear asking if you wish to update the file in the archive - choose "Yes" and the JAR will be updated.

I think currently your api's actually responding the way it should. The first 100 records on the page in the overall order of objects you are maintaining. Your explanation tells that you are using some kind of ordering ids to define the order of your objects for pagination.

Now, in case you want that page 2 should always start from 101 and end at 200, then you must make the number of entries on the page as variable, since they are subject to deletion.

You should do something like the below pseudocode:

page_max = 100
def get_page_results(page_no) :

    start = (page_no - 1) * page_max + 1
    end = page_no * page_max

    return fetch_results_by_id_between(start, end)

The manpage for types.h says:

size_t shall be an unsigned integer type

First off, in a real application, you would never get database connection info in a servlet; you would configure it in your app server.

There are ways, however, of testing Servlets without having a container running. One is to use mock objects. Spring provides a set of very useful mocks for things like HttpServletRequest, HttpServletResponse, HttpServletSession, etc:

http://static.springsource.org/spring/docs/3.0.x/api/org/springframework/mock/web/package-summary.html

Using these mocks, you could test things like

What happens if username is not in the request?

What happens if username is in the request?

etc

You could then do stuff like:

import static org.junit.Assert.assertEquals;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.junit.Before;
import org.junit.Test;
import org.springframework.mock.web.MockHttpServletRequest;
import org.springframework.mock.web.MockHttpServletResponse;

public class MyServletTest {
    private MyServlet servlet;
    private MockHttpServletRequest request;
    private MockHttpServletResponse response;

    @Before
    public void setUp() {
        servlet = new MyServlet();
        request = new MockHttpServletRequest();
        response = new MockHttpServletResponse();
    }

    @Test
    public void correctUsernameInRequest() throws ServletException, IOException {
        request.addParameter("username", "scott");
        request.addParameter("password", "tiger");

        servlet.doPost(request, response);

        assertEquals("text/html", response.getContentType());

        // ... etc
    }
}

JLabel label = new JLabel("fax", SwingConstants.RIGHT);

After running "kubeinit" command, kubernetes asks you to run following as regular user

mkdir -p $HOME/.kube

sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config

sudo chown $(id -u):$(id -g) $HOME/.kube/config

But if you run this as a regular user, you will get "The connection to the server localhost:8080 was refused - did you specify the right host or port?" when trying to access as a root user and vice versa. So try accessing "kubectl" as the user who executed the above commands.

They serve the actual image inside CSS so there will be less HTTP requests per page.

I have used following code to read "xls and xlsx" :

    include 'PHPExcel/IOFactory.php';

    $location='sample-excel-files.xlsx';

    $objPHPExcel = PHPExcel_IOFactory::load($location);
    $sheet = $objPHPExcel->getSheet(0);
    $total_rows = $sheet->getHighestRow();
    $total_columns = $sheet->getHighestColumn();
    $set_excel_query_all=array();
    for($row =2; $row <= $total_rows; $row++) {
        $singlerow = $sheet->rangeToArray('A' . $row . ':' . $total_columns . $row, NULL, TRUE, FALSE);
        $single_row=$singlerow[0];
        $set_excel_query['store_id']=$single_row[0];
        $set_excel_query['employee_uid']=$single_row[1];
        $set_excel_query['opus_id']=$single_row[2];
        $set_excel_query['item_description']=$single_row[3];
        if($single_row[4])
        {
            $set_excel_query['opus_transaction_date']= date('Y-m-d', PHPExcel_Shared_Date::ExcelToPHP($single_row[4]));
        }
        $set_excel_query['opus_transaction_num']=$single_row[5];
        $set_excel_query['opus_invoice_num']=$single_row[6];
        $set_excel_query['customer_name']=$single_row[7];
        $set_excel_query['mobile_num']=$single_row[8];
        $set_excel_query['opus_amount']=$single_row[9];
        $set_excel_query['rq4_amount']=$single_row[10];
        $set_excel_query['difference']=$single_row[11];
        $set_excel_query['ocomment']=$single_row[12];
        $set_excel_query['mark_delete']=$single_row[13];
        if($single_row[14])
        {
            $set_excel_query['upload_date']= date('Y-m-d', PHPExcel_Shared_Date::ExcelToPHP($single_row[14]));
        }
        $set_excel_query_all[]=$set_excel_query;
    }

   print_r($set_excel_query_all); 

I wrote with parameters that are predefined

They are not "predefined" logically, somewhere inside your code. But as arguments of SP they have no default values and are required. To avoid passing those params explicitly you have to define default values in SP definition:

Alter Procedure [Test]
    @StartDate AS varchar(6) = NULL, 
    @EndDate AS varchar(6) = NULL
AS
...

NULLs or empty strings or something more sensible - up to you. It does not matter since you are overwriting values of those arguments in the first lines of SP.

Now you can call it without passing any arguments e.g. exec dbo.TEST

You need to set the scope of the dependency to 'provided' in your POM.

http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#Dependency_Scope

<dependency>  
  <groupId>javax.servlet</groupId>
  <artifactId>servlet-api</artifactId>
  <version>2.4</version>
  <scope>provided</scope>
</dependency>

Then everything will be fine.

I set the opacity to 0. This made it disappear but still function when you click on it.

You can do some tricks like that:

<style>
    @page {
        size: 21cm 29.7cm;
        size: landscape
        /*margin: 30mm 45mm 30mm 45mm;*/

    }
    .whater{
        opacity: 0.05;
        height: 100%;
        width: 100%;
        position: absolute;
        z-index: 9999;
    }
</style>

In body tag:

<img src="YOUR IMAGE URL" class="whater"/>

'Effectively final' is a variable which would not give compiler error if it were to be appended by 'final'

From a article by 'Brian Goetz',

Informally, a local variable is effectively final if its initial value is never changed -- in other words, declaring it final would not cause a compilation failure.

lambda-state-final- Brian Goetz

char * const a;

*a is writable, but a is not; in other words, you can modify the value pointed to by a, but you cannot modify a itself. a is a constant pointer to char.

const char * a; 

a is writable, but *a is not; in other words, you can modify a (pointing it to a new location), but you cannot modify the value pointed to by a.

Note that this is identical to

char const * a;

In this case, a is a pointer to a const char.

Trying to run cleanup while your files are open gave me problems. as soon as I closed my application (Visual studio) I ran clean up and it was successful

In a Linux server, using default implementation of ses will expect files in .aws/credentials file. You can put following content in credential file at the location below and it will work. /home/local/<your service account>/.aws/credentials.

[default]
aws_access_key_id=<your access key>
aws_secret_access_key=<your secret access key>

I've been using Bitvise SSH Server and it's really great. From install to administration it does it all through a GUI so you won't be putting together a sshd_config file. Plus if you use their client, Tunnelier, you get some bonus features (like mapping shares, port forwarding setup up server side, etc.) If you don't use their client it will still work with the Open Source SSH clients.

It's not Open Source and it costs $39.95, but I think it's worth it.

UPDATE 2009-05-21 11:10: The pricing has changed. The current price is $99.95 per install for commercial, but now free for non-commercial/personal use. Here is the current pricing.

public View recentView;

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        //Create a relative layout and add a button
        relativeLayout = new RelativeLayout(this);
        btn = new Button(this);
        btn.setId((int)System.currentTimeMillis());
        recentView = btn;
        btn.setText("Click me");
        relativeLayout.addView(btn);


        setContentView(relativeLayout);

        btn.setOnClickListener(new View.OnClickListener() {

            @Overr ide
            public void onClick(View view) {

                //Create a textView, set a random ID and position it below the most recently added view
                textView = new TextView(ActivityName.this);
                textView.setId((int)System.currentTimeMillis());
                layoutParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
                layoutParams.addRule(RelativeLayout.BELOW, recentView.getId());
                textView.setText("Time: "+System.currentTimeMillis());
                relativeLayout.addView(textView, layoutParams);
                recentView = textView;
            }
        });
    }

This can be modified to display each element of a String array in different TextViews.

First you need to download the latest support repository (17 by the time I write this) from internal SDK manager of Android Studio or from the stand alone SDK manager. Then you can add compile 'com.android.support:appcompat-v7:23.0.0' or any other support library you want to your build.gradle file. (Don't forget the last .0)

CodeLens is not available in the Community editions. You need Professional or higher to switch it on.

In VS2015, one way to "get" CodeLens was to install the SQL Server Developer Tools (SSDT) but I believe this has been rectified in VS2017.

Still you can get all method reference by right clicking on the method and "Find All references"

You need the javax.mail.jar library. Download it from the Java EE JavaMail GitHub page and add it to your IntelliJ project:

1. Download javax.mail.jar
2. Navigate to File > Project Structure...
3. Go to the Libraries tab
4. Click on the + button (Add New Project Library)
5. Browse to the javax.mail.jar file
6. Click OK to apply the changes

Most of the time you can't - depending on the host. You can contact the support team where your hosting is subscribed to, and if they confirmed that it is really not allowed, you can just set up the composer on your dev machine, and commit and push all dependencies to your live server using Git or whatever you prefer.

If you don't want something complicated, then:

import warnings
warnings.filterwarnings("ignore", category=FutureWarning)

You should add next permission:

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

And then here is usages in code:

val externalFilesDir = context.getExternalFilesDir(DIRECTORY_DOWNLOADS)

Apply the (soft) shadow on the view's layer, like this:

UILabel *label = [[UIabel alloc] init];
label.layer.shadowColor = [[UIColor whiteColor] CGColor];
label.layer.shadowOpacity = 1.0;

You should add then function to instance. Promise will recognize it as a thenable object with Promise.resolve automatically

const asyncSymbol = Symbol();
class MyClass {
    constructor() {
        this.asyncData = null
    }
    then(resolve, reject) {
        return (this[asyncSymbol] = this[asyncSymbol] || new Promise((innerResolve, innerReject) => {
            this.asyncData = { a: 1 }
            setTimeout(() => innerResolve(this.asyncData), 3000)
        })).then(resolve, reject)
    }
}

async function wait() {
    const asyncData = await new MyClass();
    alert('run 3s later')
    alert(asyncData.a)
}

You just need to add an "A" record in the DNS manager on Godaddy. In that "A" record put your IP from dreamhost.

I know this works since I'm doing the very same thing.

One possibility which has not been mentioned so far is that you might not be editing the file you think you are. i.e. your editor might have a different cwd than you had in mind.

Run 'more' on the file you're compiling to double check that it does indeed have the contents you hope it does. Hope that helps!

Strong: Basically Used With Properties we used to get or send data from/into another classes. Weak: Usually all outlets, connections are of Weak type from Interface.

Nonatomic: Such type of properties are used in conditions when we don't want to share our outlet or object into different simultaneous Threads. In other words, Nonatomic instance make our properties to deal with one thread at a time. Hopefully it helpful for you.

This is also an option:

x==2 && dosomething();

dosomething() will only be called if x==2 is evaluated to true. This is called Short-circuiting.

It is not commonly used in cases like this and you really shouldn't write code like this. I encourage this simpler approach:

if(x==2) dosomething();

You should write readable code at all times; if you are worried about file size, just create a minified version of it with help of one of the many JS compressors. (e.g Google's Closure Compiler)

%d--> for int

%u--> for unsigned int

%ld--> for long int or long

%lu--> for unsigned long int or long unsigned int or unsigned long

%lld--> for long long int or long long

%llu--> for unsigned long long int or unsigned long long

<input type="text" value="Your value">

Use the value attribute for the pre filled in values.

Add both http and https configuration:

export JAVA_OPTS="$JAVA_OPTS -Dhttp.proxyHost=yourserver -Dhttp.proxyPort=8080 -Dhttp.proxyUser=username -Dhttp.proxyPassword=password"

export JAVA_OPTS="$JAVA_OPTS -Dhttps.proxyHost=yourserver -Dhttps.proxyPort=8080 -Dhttps.proxyUser=username -Dhttps.proxyPassword=password"

(https config is must, since many urls referred by the sbt libraries are https)

In fact, I even had an extra setting 'http.proxySet' to 'true' in both configuration entries.

Simple answer is here:

<div style="text-align: right;">
    anything:

    </select>
</div>

Steps to convert .py to .exe in Python 3.6

1. Install Python 3.6.
2. Install cx_Freeze, (open your command prompt and type pip install cx_Freeze.
3. Install idna, (open your command prompt and type pip install idna.
4. Write a .py program named myfirstprog.py.
5. Create a new python file named setup.py on the current directory of your script.
6. In the setup.py file, copy the code below and save it.
7. With shift pressed right click on the same directory, so you are able to open a command prompt window.
8. In the prompt, type python setup.py build
9. If your script is error free, then there will be no problem on creating application.
10. Check the newly created folder build. It has another folder in it. Within that folder you can find your application. Run it. Make yourself happy.

See the original script in my blog.

setup.py:

from cx_Freeze import setup, Executable

base = None    

executables = [Executable("myfirstprog.py", base=base)]

packages = ["idna"]
options = {
    'build_exe': {    
        'packages':packages,
    },    
}

setup(
    name = "<any name>",
    options = options,
    version = "<any number>",
    description = '<any description>',
    executables = executables
)

EDIT:

• be sure that instead of myfirstprog.py you should put your .pyextension file name as created in step 4;
• you should include each imported package in your .py into packages list (ex: packages = ["idna", "os","sys"])
• any name, any number, any description in setup.py file should not remain the same, you should change it accordingly (ex:name = "<first_ever>", version = "0.11", description = '' )
• the imported packages must be installed before you start step 8.

You'll need to compile it using:

g++ inputfile.cpp -o outputbinary

The file you are referring has a missing #include <cstdlib> directive, if you also include that in your file, everything shall compile fine.

When you're working with strings in PHP you'll need to pay special attention to the formation, using " or '

$string = 'Hello, world!';
$string = "Hello, world!";

Both of these are valid, the following is not:

$string = "Hello, world';

You must also note that ' inside of a literal started with " will not end the string, and vice versa. So when you have a string which contains ', it is generally best practice to use double quotation marks.

$string = "It's ok here";

Escaping the string is also an option

$string = 'It\'s ok here too';

More information on this can be found within the documentation

I ran across this post today as I was running into the same issue and had the same problem of the javascript not running with the CDATA tags listed above. I corrected the CDATA tags to look like:

<script type="text/javascript">
//<![CDATA[ 

your javascript code here

//]]>
</script>

Then everything worked perfectly!

I think (I'm not certain) that foreign key constraints won't do precisely what you want given your table design. Perhaps the best thing to do is to define a stored procedure that will delete a category the way you want, and then call that procedure whenever you want to delete a category.

CREATE PROCEDURE `DeleteCategory` (IN category_ID INT)
LANGUAGE SQL
NOT DETERMINISTIC
MODIFIES SQL DATA
SQL SECURITY DEFINER
BEGIN

DELETE FROM
    `products`
WHERE
    `id` IN (
        SELECT `products_id`
        FROM `categories_products`
        WHERE `categories_id` = category_ID
    )
;

DELETE FROM `categories`
WHERE `id` = category_ID;

END

You also need to add the following foreign key constraints to the linking table:

ALTER TABLE `categories_products` ADD
    CONSTRAINT `Constr_categoriesproducts_categories_fk`
    FOREIGN KEY `categories_fk` (`categories_id`) REFERENCES `categories` (`id`)
    ON DELETE CASCADE ON UPDATE CASCADE,
    CONSTRAINT `Constr_categoriesproducts_products_fk`
    FOREIGN KEY `products_fk` (`products_id`) REFERENCES `products` (`id`)
    ON DELETE CASCADE ON UPDATE CASCADE

The CONSTRAINT clause can, of course, also appear in the CREATE TABLE statement.

Having created these schema objects, you can delete a category and get the behaviour you want by issuing CALL DeleteCategory(category_ID) (where category_ID is the category to be deleted), and it will behave how you want. But don't issue a normal DELETE FROM query, unless you want more standard behaviour (i.e. delete from the linking table only, and leave the products table alone).

You can use this, it works fine:

<input type="date" class="form1"  
  value="{{date | date:MM/dd/yyyy}}"
  ng-model="date" 
  name="id" 
  validatedateformat 
  data-date-format="mm/dd/yyyy"
  maxlength="10" 
  id="id" 
  calendar 
  maxdate="todays"
  ng-click="openCalendar('id')">
    <span class="input-group-addon">
      <span class="glyphicon glyphicon-calendar" ng-click="openCalendar('id')"></span>
    </span>
</input>

If you're trying to query an Oracle database, you might want to use

select owner, table_name 
from all_tab_columns
where column_name = 'ColName';

Like ?egDwight said, you can use the HTML entity &infin; or ∞. A easy source of getting these codes, is to look at this entity list.

You can also use them in CSS, which was what I was looking for, just like font-awesome does. A simple CSS based solution would be to have something like:

.infinity-ico:before {
    content: '\221E';
}

I use this function in all my js projects

You call it: hideAndResetModals("#IdModalDialog")

You define if:

function hideAndResetModals(modalID)
{
    $(modalID).modal('hide');
    clearValidation(modalID); //You implement it if you need it. If not, you can remote this line
    $(modalID).on('hidden.bs.modal', function () 
    {
        $(modalID).find('form').trigger('reset');  
    });
}

Two Answers

1. Answer to the asked question.

2. A simple change equals a better way!

Answer 1 - Pass the Vars Array to the __construct() in a class, you could also leave the construct empty and pass the Arrays through your functions instead.

<?php

// Create an Array with all needed Sub Arrays Example: 
// Example Sub Array 1
$content_arrays["modals"]= array();
// Example Sub Array 2
$content_arrays["js_custom"] = array();

// Create a Class
class Array_Pushing_Example_1 {

    // Public to access outside of class
    public $content_arrays;

    // Needed in the class only
    private $push_value_1;
    private $push_value_2;
    private $push_value_3;
    private $push_value_4;  
    private $values;
    private $external_values;

    // Primary Contents Array as Parameter in __construct

Answer 2 - A simple change however would put it inline with modern standards. Just declare your Arrays in the Class.

<?php

// Create a Class
class Array_Pushing_Example_2 {

    // Public to access outside of class
    public $content_arrays;

    // Needed in the class only
    private $push_value_1;
    private $push_value_2;
    private $push_value_3;
    private $push_value_4;  
    private $values;
    private $external_values;

    // Declare Contents Array and Sub Arrays in __construct
    public function __construct(){

        // Declare them
        $this->content_arrays["modals"] = array();
        $this->content_arrays["js_custom"] = array();

    }

    // Push Values from in the Array using Public Function
    public function array_push_1(){

        // Values
        $this->push_values_1 = array(1,"2B or not 2B",3,"42",5);
        $this->push_values_2 = array("a","b","c");

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_1 as $this->values){

            $this->content_arrays["js_custom"][] = $this->values;

        }

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_2 as $this->values){

            $this->content_arrays["modals"][] = $this->values;

        }

    // Return Primary Array with New Values
    return $this->content_arrays;

    }

    // GET Push Values External to the Class with Public Function
    public function array_push_2($external_values){

        $this->push_values_3 = $external_values["values_1"];
        $this->push_values_4 = $external_values["values_2"];

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_3 as $this->values){

            $this->content_arrays["js_custom"][] = $this->values;

        }

        // Loop Values and Push Values to Sub Array
        foreach($this->push_values_4 as $this->values){

            $this->content_arrays["modals"][] = $this->values;

        }

    // Return Primary Array with New Values
    return $this->content_arrays;

    }

}

// Start the Class without the Contents Array as a Parameter
$content_arrays = new Array_Pushing_Example_2();

// Push Internal Values to the Arrays
$content_arrays->content_arrays = $content_arrays->array_push_1();

// Push External Values to the Arrays
$external_values = array();
$external_values["values_1"] = array("car","house","bike","glass");
$external_values["values_2"] = array("FOO","foo");
$content_arrays->content_arrays = $content_arrays->array_push_2($external_values);

// The Output
echo "Array Custom Content Results 1";
echo "<br>";
echo "<br>";

echo "Modals - Count: ".count($content_arrays->content_arrays["modals"]);
echo "<br>";
echo "-------------------";
echo "<br>";

// Get Modals Array Results
foreach($content_arrays->content_arrays["modals"] as $modals){

    echo $modals;
    echo "<br>";

}

echo "<br>";
echo "JS Custom - Count: ".count($content_arrays->content_arrays["js_custom"]);

echo "-------------------";
echo "<br>";

// Get JS Custom Array Results
foreach($content_arrays->content_arrays["js_custom"] as $js_custom){

    echo $js_custom;
    echo "<br>";


}

echo "<br>";

?>

Both options output the same information and allow a function to push and retrieve information from an Array and sub Arrays to any place in the code(Given that the data has been pushed first). The second option gives more control over how the data is used and protected. They can be used as is just modify to your needs but if they were used to extend a Controller they could share their values among any of the Classes the Controller is using. Neither method requires the use of a Global(s).

Output:

Array Custom Content Results

Modals - Count: 5

a

b

c

FOO

foo

JS Custom - Count: 9

1

2B or not 2B

3

42

5

car

house

bike

glass

pids=$(pgrep <name>)

will get you the pids of all processes with the given name. To kill them all, use

kill -9 $pids

To refrain from using a variable and directly kill all processes with a given name issue

pkill -9 <name>

A bit old but just in case someone new is looking for a solution, updating your PHP version can fix the issue.

Also you should be committing your composer.lock file and doing a composer install on a production environment which is less resource intensive.

The best practice is definitely to avoid loops or recursions in Matlab.

Between sum(A(:)) and sum(sum(A)). In my experience, arrays in Matlab seems to be stored in a continuous block in memory as stacked column vectors. So the shape of A does not quite matter in sum(). (One can test reshape() and check if reshaping is fast in Matlab. If it is, then we have a reason to believe that the shape of an array is not directly related to the way the data is stored and manipulated.)

As such, there is no reason sum(sum(A)) should be faster. It would be slower if Matlab actually creates a row vector recording the sum of each column of A first and then sum over the columns. But I think sum(sum(A)) is very wide-spread amongst users. It is likely that they hard-code sum(sum(A)) to be a single loop, the same to sum(A(:)).

Below I offer some testing results. In each test, A=rand(size) and size is specified in the displayed texts.

First is using tic toc.

In my experience, both timers are only meaningful up to .1s. So if you have similar experience with Matlab timers, none of the tests can discern sum(A(:)) and sum(sum(A)).

I tried the largest size allowed on my computer a few more times.

Size 10000x10000

0.2808
The cputime for sum(sum(A)) in seconds is 
0.312

Size 10000x10000

The cputime for sum(sum(A)) in seconds is

They seem equivalent. Either one is good. But sum(sum(A)) requires that you know the dimension of your array is 2.

I think you can use REGEXP instead of LIKE

SELECT trecord FROM `tbl` WHERE (trecord REGEXP '^ALA[0-9]')

This looks like a homework question, so I'll just give you a few pointers:

Try to give good distinctive variable names. Here you used "fileName" first for the directory, and then for the file. That is confusing, and won't help you solve the problem. Use different names for different things.

You're not using Scanner for anything, and it's not needed here, get rid of it.

Furthermore, the accept method should return a boolean value. Right now, you are trying to return a String. Boolean means that it should either return true or false. For example return a > 0; may return true or false, depending on the value of a. But return fileName; will just return the value of fileName, which is a String.

What is the style item to make it disappear?

In order to remove the shadow add this to your app theme:

<style name="MyAppTheme" parent="android:Theme.Holo.Light">
    <item name="android:windowContentOverlay">@null</item>
</style>

UPDATE: As @Quinny898 stated, on Android 5.0 this has changed, you have to call setElevation(0) on your action bar. Note that if you're using the support library you must call it to that like so:

getSupportActionBar().setElevation(0);

I use os.system

import os
os.system("pdftoppm -png {} {}".format(path2pdf, os.path.join(tmpdirname, "temp")))

You can read here about the behaviour of attributes in many different browsers, including IE.

element.setAttribute() should do the trick, even in IE. Did you try it? If it doesn't work, then maybe element.attributeName = 'value' might work.

Answer is indeed the one provided by zerkms, as stated on Option 1:

Option 1: which does not risk damage to data integrity:

1. Remove constraints
2. Perform TRUNCATE
3. Delete manually the rows that now have references to nowhere
4. Create constraints

The tricky part is Removing constraints, so I want to tell you how, in case someone needs to know how to do that:

1. Run SHOW CREATE TABLE <Table Name> query to see what is your FOREIGN KEY's name (Red frame in below image):

   

2. Run ALTER TABLE <Table Name> DROP FOREIGN KEY <Foreign Key Name>. This will remove the foreign key constraint.

3. Drop the associated Index (through table structure page), and you are done.

to re-create foreign keys:

ALTER TABLE <Table Name>
ADD FOREIGN KEY (<Field Name>) REFERENCES <Foreign Table Name>(<Field Name>);

commit your code using

git commit -m "first commit"

then config your mail id using

git config user.email "[email protected]"

this is work for me

Transaction can be defined as a collection of task that are considered as minimum processing unit. Each minimum processing unit can not be divided further.

The main operation of a transaction are read and write.

All transaction must contain four properties that commonly known as ACID properties for the purpose of ensuring accuracy , completeness and data integrity.

Add to VM options: -Dspring.profiles.active=dev

Or you can add it to the build.gradle file to make it work: bootRun.systemProperties = System.properties.

I can now successfully retrieve the version of an APK file from its binary XML data.

This topic is where I got the key to my answer (I also added my version of Ribo's code): How to parse the AndroidManifest.xml file inside an .apk package

Additionally, here's the XML parsing code I wrote, specifically to fetch the version:

XML Parsing

/**
 * Verifies at Conductor APK path if package version if newer 
 * 
 * @return True if package found is newer, false otherwise
 */
public static boolean checkIsNewVersion(String conductorApkPath) {

    boolean newVersionExists = false;

    // Decompress found APK's Manifest XML
    // Source: https://stackoverflow.com/questions/2097813/how-to-parse-the-androidmanifest-xml-file-inside-an-apk-package/4761689#4761689
    try {

        if ((new File(conductorApkPath).exists())) {

            JarFile jf = new JarFile(conductorApkPath);
            InputStream is = jf.getInputStream(jf.getEntry("AndroidManifest.xml"));
            byte[] xml = new byte[is.available()];
            int br = is.read(xml);

            //Tree tr = TrunkFactory.newTree();
            String xmlResult = SystemPackageTools.decompressXML(xml);
            //prt("XML\n"+tr.list());

            if (!xmlResult.isEmpty()) {

                InputStream in = new ByteArrayInputStream(xmlResult.getBytes());

                // Source: http://developer.android.com/training/basics/network-ops/xml.html
                XmlPullParser parser = Xml.newPullParser();
                parser.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, false);

                parser.setInput(in, null);
                parser.nextTag();

                String name = parser.getName();
                if (name.equalsIgnoreCase("Manifest")) {

                    String pakVersion = parser.getAttributeValue(null, "versionName");
                            //NOTE: This is specific to my project. Replace with whatever is relevant on your side to fetch your project's version
                    String curVersion = SharedData.getPlayerVersion();

                    int isNewer = SystemPackageTools.compareVersions(pakVersion, curVersion); 

                    newVersionExists = (isNewer == 1); 
                }

            }
        }

    } catch (Exception ex) {
        android.util.Log.e(TAG, "getIntents, ex: "+ex);
        ex.printStackTrace();
    }

    return newVersionExists;
}

Version Comparison (seen as SystemPackageTools.compareVersions in previous snippet) NOTE: This code is inspired from the following topic: Efficient way to compare version strings in Java

public static final int compareVersions(String ver1, String ver2) {

    String[] vals1 = ver1.split("\\.");
    String[] vals2 = ver2.split("\\.");
    int i=0;
    while(i<vals1.length&&i<vals2.length&&vals1[i].equals(vals2[i])) {
      i++;
    }

    if (i<vals1.length&&i<vals2.length) {
        int diff = Integer.valueOf(vals1[i]).compareTo(Integer.valueOf(vals2[i]));
        return diff<0?-1:diff==0?0:1;
    }

    return vals1.length<vals2.length?-1:vals1.length==vals2.length?0:1;
}

I hope this helps.

For above query apply below css for a

There is very little overall difference between GCC 4.8 and clang 3.3 in terms of speed of the resulting binary. In most cases code generated by both compilers performs similarly. Neither of these two compilers dominates the other one.

Benchmarks telling that there is a significant performance gap between GCC and clang are coincidental.

Program performance is affected by the choice of the compiler. If a developer or a group of developers is exclusively using GCC then the program can be expected to run slightly faster with GCC than with clang, and vice versa.

From developer viewpoint, a notable difference between GCC 4.8+ and clang 3.3 is that GCC has the -Og command line option. This option enables optimizations that do not interfere with debugging, so for example it is always possible to get accurate stack traces. The absence of this option in clang makes clang harder to use as an optimizing compiler for some developers.

In my case it was POST submission of a json to be processed and get a return value. I cross checked logs of my app server with and without nginx. What i got was my location was not getting appended to proxy_pass url and the version of HTTP protocol version is different.

• Without nginx: "POST /xxQuery HTTP/1.1" 200 -
• With nginx: "POST / HTTP/1.0" 405 -

My earlier location block was

location /xxQuery {
    proxy_method POST;
    proxy_pass http://127.0.0.1:xx00/;
    client_max_body_size 10M;
}

I changed it to

location /xxQuery {
    proxy_method POST;
    proxy_http_version 1.1;
    proxy_pass http://127.0.0.1:xx00/xxQuery;
    client_max_body_size 10M;
}

It worked.

If checked:

$( "SELECTOR" ).attr( "checked" )  // Returns ‘true’ if present on the element, returns undefined if not present
$( "SELECTOR" ).prop( "checked" ) // Returns true if checked, false if unchecked.
$( "SELECTOR" ).is( ":checked" ) // Returns true if checked, false if unchecked.

Get the checked val:

$( "SELECTOR:checked" ).val()

Get the checked val numbers:

$( "SELECTOR:checked" ).length

Check or uncheck checkbox

$( "SELECTOR" ).prop( "disabled", false );
$( "SELECTOR" ).prop( "checked", true );

there is the class I mentioned in the comment we had with Sean Patrick Floyd : I did it with a peculiar use which needs WeakReference, but you can change it by any object with ease.

            throw new IndexOutOfBoundsException( "Index out of bounds (set) : [ y = " + y + "]" );
        }
        _array[x][y] = new WeakReference<T>( o );

        // store local "visible" references : avoids deletion, works in FIFO mode
        _buffer.add( o );
        if(_buffer.size() > _bufferSize)
        {
            _buffer.poll();
        }
    }

}

Example of how to use it :

// a 5x5 array, with at most 10 elements "bufferized" -> the last 10 elements will not be taken by GC process
Array2DWeakRefsBuffered<Image> myArray = new Array2DWeakRefsBuffered<Image>(5,5,10);
Image img = myArray.set(anImage,0,0);
if(myArray.exists(3,3))
{
    System.out.println("Image at 3,3 is still in memory");
}

A good approach is to have a common base class for all your entities. In this base class, you can have your id property if it is commonly named in all your entities (a common design), your creation and last update date properties.

For the creation date, you simply keep a java.util.Date property. Be sure, to always initialize it with new Date().

For the last update field, you can use a Timestamp property, you need to map it with @Version. With this Annotation the property will get updated automatically by Hibernate. Beware that Hibernate will also apply optimistic locking (it's a good thing).

@user755806 I do not believe that your question was answered. I took your code but used the 'foo' example string, added a lower function and also found the length of the hash returned. In sqlplus or Oracle's sql developer Java database client you can use this to call the md5sum of a value. The column formats clean up the presentation.

column hash_key format a34;
column hash_key_len format 999999;
select dbms_obfuscation_toolkit.md5(
          input => UTL_RAW.cast_to_raw('foo')) as hash_key,
       length(dbms_obfuscation_toolkit.md5(
          input => UTL_RAW.cast_to_raw('foo'))) as hash_key_len
 from dual;

The result set

HASH_KEY                           HASH_KEY_LEN
---------------------------------- ------------
acbd18db4cc2f85cedef654fccc4a4d8             32

is the same value that is returned from a Linux md5sum command.

echo -n foo | md5sum
acbd18db4cc2f85cedef654fccc4a4d8  -

1. Yes you can call or execute the sql statement directly in sqlplus or sql developer. I tested the sql statement in both clients against 11g.
2. You can use any C, C#, Java or other programming language that can send a statement to the database. It is the database on the other end of the call that needs to be able to understand the sql statement. In the case of 11 g, the code will work.
3. @tbone provides an excellent warning about the deprecation of the dbms_obfuscation_toolkit. However, that does not mean your code is unusable in 12c. It will work but you will want to eventually switch to dbms_crypto package. dbms_crypto is not available in my version of 11g.

WARNING: This solution has security risks.

Try running the container as privileged:

sudo docker run --privileged=true -i -v /data1/Downloads:/Downloads ubuntu bash

Another option (that I have not tried) would be to create a privileged container and then create non-privileged containers inside of it.

Simple one, add before Main

[DllImport("USER32.DLL", CharSet = CharSet.Unicode)]
public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
[DllImport("USER32.DLL")]
public static extern bool SetForegroundWindow(IntPtr hWnd);

Code inside Main/Method:

string className = "IEFrame";
string windowName = "New Tab - Windows Internet Explorer";
IntPtr IE = FindWindow(className, windowName);
if (IE == IntPtr.Zero)
{
   return;
}
SetForegroundWindow(IE);
InputSimulator.SimulateKeyPress(VirtualKeyCode.F5);

Note:

1. Add InputSimulator as reference. To download Click here

If you can change the order of the elements:

 int[] myArray = new int[]{1, 3, 8, 5, 7, };
 Arrays.sort(myArray);
 int max = myArray[myArray.length - 1];

If you can't change the order of the elements:

int[] myArray = new int[]{1, 3, 8, 5, 7, };
int max = Integer.MIN_VALUE;
for(int i = 0; i < myArray.length; i++) {
      if(myArray[i] > max) {
         max = myArray[i];
      }
}

The above answers require you to malloc a new stream object.

public <T>
boolean containsByLambda(Collection<? extends T> c, Predicate<? super T> p) {

    for (final T z : c) {
        if (p.test(z)) {
            return true;
        }
    }
    return false;
}

public boolean containsTabById(TabPane tabPane, String id) {
    return containsByLambda(tabPane.getTabs(), z -> z.getId().equals(id));
}
...
if (containsTabById(tabPane, idToCheck))) {
   ...
}

Here's a pure CSS solution, similar to DarkBee's answer, but without the need for an extra .wrapper div:

.dimmed {
  position: relative;
}

.dimmed:after {
  content: " ";
  z-index: 10;
  display: block;
  position: absolute;
  height: 100%;
  top: 0;
  left: 0;
  right: 0;
  background: rgba(0, 0, 0, 0.5);
}

I'm using rgba here, but of course you can use other transparency methods if you like.

You could solve this with some simple gazpacho parsing:

from gazpacho import Soup

soup = Soup(html)
tds = soup.find("td", {"class": "pos"})
tds[1].find("strong").text

Which will output:

text I am looking for

'SET' is forgotten

ALTER TABLE ONLY users ALTER COLUMN lang SET DEFAULT 'en_GB';

AFAIK all you can do is omit the returns to make things more compact in C++:

switch(Answer)
{
    case 1: case 2: case 3: case 4:
        cout << "You need more cars.";
        break;
    ...
}

(You could remove the other returns as well, of course.)

This is a tricky subject. In the end, if you invoke pip it will invoke either pip2 or pip3, depending on how you set your system up.

here is updated code of the redim preseve method with variabel declaration, hope @Control Freak is fine with it:)

Option explicit
'redim preserve both dimensions for a multidimension array *ONLY
Public Function ReDimPreserve(aArrayToPreserve As Variant, nNewFirstUBound As Variant, nNewLastUBound As Variant) As Variant
    Dim nFirst As Long
    Dim nLast As Long
    Dim nOldFirstUBound As Long
    Dim nOldLastUBound As Long

    ReDimPreserve = False
    'check if its in array first
    If IsArray(aArrayToPreserve) Then
        'create new array
        ReDim aPreservedArray(nNewFirstUBound, nNewLastUBound)
        'get old lBound/uBound
        nOldFirstUBound = UBound(aArrayToPreserve, 1)
        nOldLastUBound = UBound(aArrayToPreserve, 2)
        'loop through first
        For nFirst = LBound(aArrayToPreserve, 1) To nNewFirstUBound
            For nLast = LBound(aArrayToPreserve, 2) To nNewLastUBound
                'if its in range, then append to new array the same way

        'return the array redimmed
        If IsArray(aPreservedArray) Then ReDimPreserve = aPreservedArray
    End If
End Function

You can use the following code

name ='mypic'
plt.savefig('path_to_file/{}'.format(name))

If you want to save in same folder where your code lies,ignore the path_to_file and just format with name. If you have folder name 'Images' in the just one level outside of your python script, you can use,

name ='mypic'
plt.savefig('Images/{}'.format(name))

The default file type in saving is '.png' file format. If you want to save in loop, then you can use the unique name for each file such as counter of the for loop. If i is the counter,

plt.savefig('Images/{}'.format(i))

Hope this helps.

For me the inclusion of "Require local" helped to solve Error 403. The alias config file looks like this:

Alias /mytest/ "C:/mytest/" 

<Directory "C:/mytest/">
    Options Indexes FollowSymLinks MultiViews
    AllowOverride all
        Order allow,deny
    Allow from all
    Require local
</Directory>

[TestMethod]
public void BraceEscapingTest()
{
    var result = String.Format("Foo {{0}}", "1,2,3");  //"1,2,3" is not parsed
    Assert.AreEqual("Foo {0}", result);

    result = String.Format("Foo {{{0}}}", "1,2,3");
    Assert.AreEqual("Foo {1,2,3}", result);

    result = String.Format("Foo {0} {{bar}}", "1,2,3");
    Assert.AreEqual("Foo 1,2,3 {bar}", result);

    result = String.Format("{{{0:N}}}", 24); //24 is not parsed, see @Guru Kara answer
    Assert.AreEqual("{N}", result);

    result = String.Format("{0}{1:N}{2}", "{", 24, "}");
    Assert.AreEqual("{24.00}", result);

    result = String.Format("{{{0}}}", 24.ToString("N"));
    Assert.AreEqual("{24.00}", result);
}

This is very short, very clear, but gives my sensibilities the creeping horrors. It's also a bit awkward to adapt to different delimiters, especially if a String (not char).

for (Item i : list)
  sb.append(',').append(i);
if (sb.charAt(0)==',') sb.deleteCharAt(0);

Ugh- nothing worked for me! I have a CentOS 7.4 machine running mariadb 5.5.64.

What I had to do was this, right after installation of mariadb from yum;

# systemctl restart mariadb
# mysql_secure_installation

The mysql_secure_installation will take you through a number of steps, including "Set root password? [Y/n]". Just say "y" and give it a password. Answer the other questions as you wish.

Then you can get in with your password, using

# mysql -u root -p

It will survive

# systemctl restart mariadb

The Key

Then, I checked the /bin/mysql_secure_installation source code to find out how it was magically able to change the root password and none of the other answers here could. The import bit is:

do_query "UPDATE mysql.user SET Password=PASSWORD('$esc_pass') WHERE User='root';"

...It says SET Password=... and not SET authentication_string = PASSWORD.... So, the proper procedure for this version (5.5.64) is:

login using mysql -u root -p , using the password you already set.
Or, stop the database and start it with:
mysql_safe --skip-grant-tables --skip-networking &

From the mysql> prompt:

use mysql;
select host,user,password from user where user = 'root';
(observe your existing passwords for root).
UPDATE mysql.user set Password = PASSWORD('your_new_cleartext_password') where user = 'root' AND host = 'localhost';
select host,user,password from user where user = 'root';
flush privileges;
quit;

kill the running mysqld_safe. restart mariadb. Login as root: mysql -u -p. Use your new password.

If you want, you can set all the root passwords at once. I think this is wise:

mysql -u root -p
(login)
use mysql;
select host,user,password from user where user = 'root';
UPDATE mysql.user set Password = PASSWORD('your_new_cleartext_password') where user = 'root';
select host,user,password from user where user = 'root';
flush privileges;
quit;

This will perform updates on all the root passwords: ie, for "localhost", "127.0.0.1", and "::1"

In the future, when I go to RHEL8 or what have you, I will try to remember to check the /bin/mysql_secure_installation and see how the guys did it, who were the ones that configured mariadb for this OS.

You can also do this by passing function with onclick event

<a onclick="getColor(this);" color="red">

<script type="text/javascript">

function getColor(el)
{
     color = $(el).attr('color');
     alert(color);
}

</script> 

I had a similar problem. I had the right settings in my web.config file but was running the application pool in Classic mode rather than Integrated mode

You can use File.WriteAllBytes

I used used fadeIn animation to replace new image for old one

ObjectAnimator.ofFloat(imageView, View.ALPHA, 0.2f, 1.0f).setDuration(1000).start();

System.out.println(resolution);

For .NET People :

string instanceId = new StreamReader(
      HttpWebRequest.Create("http://169.254.169.254/latest/meta-data/instance-id")
      .GetResponse().GetResponseStream())
    .ReadToEnd();

SVN ignore is easy to manage in TortoiseSVN. Open TortoiseSVN and right-click on file menu then select Add to ignore list.

This will add the files in the svn:ignore property. When we checking in the files then those file which is matched with svn:ignore that will be ignored and will not commit.

In Visual Studio project we have added following files to ignore:

bin obj
*.exe
*.dll
*.pdb
*.suo

We are managing source code on SVN of Comparetrap using this method successfully

You can give opacity value as

div {opacity: 0.4;}

For IE, you can specify as

div { filter:alpha(opacity=10));}

Lower the value - Higher the transparency.

NOTE: this topic is about installation issues with MS project templates.

I came here via a search in Google, I was looking for a missing Template option in Visual Studio 2017 File menu: in VS-2015, it was Export to Template and I used it to add my own standard Project Items.

Meanwhile, I found an answer.. my issue was not related to default templates and it does not need install things. The option Export to Template has been moved to the VS-2017 Project menu !

Little bit late to the party but had some problems with getting something useful out from a ReadableStream produced from a Odata $batch request using the Sharepoint Framework.

Had similar issues as OP, but the solution in my case was to use a different conversion method than .json(). In my case .text() worked like a charm. Some fiddling was however necessary to get some useful JSON from the textfile.

The accepted answer is not incorrect.

For grouped styles one can also use the ngStyle directive.

<some-element [ngStyle]="{'font-style': styleExpression, 'font-weight': 12}">...</some-element>

The official docs are here

C# 6.0 adds readonly auto properties

public object MyProperty { get; }

So when you don't need to support older compilers you can have a truly readonly property with code that's just as concise as a readonly field.

Versioning:
I think it doesn't make much difference if you are only interested in source compatibility.
Using a property is better for binary compatibility since you can replace it by a property which has a setter without breaking compiled code depending on your library.

Convention:
You are following the convention. In cases like this where the differences between the two possibilities are relatively minor following the convention is better. One case where it might come back to bite you is reflection based code. It might only accept properties and not fields, for example a property editor/viewer.

Serialization
Changing from field to property will probably break a lot of serializers. And AFAIK XmlSerializer does only serialize public properties and not public fields.

Using an Autoproperty
Another common Variation is using an autoproperty with a private setter. While this is short and a property it doesn't enforce the readonlyness. So I prefer the other ones.

Readonly field is selfdocumenting
There is one advantage of the field though:
It makes it clear at a glance at the public interface that it's actually immutable (barring reflection). Whereas in case of a property you can only see that you cannot change it, so you'd have to refer to the documentation or implementation.

But to be honest I use the first one quite often in application code since I'm lazy. In libraries I'm typically more thorough and follow the convention.

Text inside an ifdef/endif or ifndef/endif pair will be left in or removed by the pre-processor depending on the condition. ifdef means "if the following is defined" while ifndef means "if the following is not defined".

So:

#define one 0
#ifdef one
    printf("one is defined ");
#endif
#ifndef one
    printf("one is not defined ");
#endif

is equivalent to:

printf("one is defined ");

since one is defined so the ifdef is true and the ifndef is false. It doesn't matter what it's defined as. A similar (better in my opinion) piece of code to that would be:

#define one 0
#ifdef one
    printf("one is defined ");
#else
    printf("one is not defined ");
#endif

since that specifies the intent more clearly in this particular situation.

In your particular case, the text after the ifdef is not removed since one is defined. The text after the ifndef is removed for the same reason. There will need to be two closing endif lines at some point and the first will cause lines to start being included again, as follows:

     #define one 0
+--- #ifdef one
|    printf("one is defined ");     // Everything in here is included.
| +- #ifndef one
| |  printf("one is not defined "); // Everything in here is excluded.
| |  :
| +- #endif
|    :                              // Everything in here is included again.
+--- #endif

First, create a empty DataFrame with column names, after that, inside the for loop, you must define a dictionary (a row) with the data to append:

df = pd.DataFrame(columns=['A'])
for i in range(5):
    df = df.append({'A': i}, ignore_index=True)
df
   A
0  0
1  1
2  2
3  3
4  4

If you want to add a row with more columns, the code will looks like this:

df = pd.DataFrame(columns=['A','B','C'])
for i in range(5):
    df = df.append({'A': i,
                    'B': i * 2,
                    'C': i * 3,
                   }
                   ,ignore_index=True
                  )
df
    A   B   C
0   0   0   0
1   1   2   3
2   2   4   6
3   3   6   9
4   4   8   12

InstallUtil classes ( ServiceInstaller ) are considered an anti-pattern by the Windows Installer community. It's a fragile, out of process, reinventing of the wheel that ignores the fact that Windows Installer has built-in support for Services.

Visual Studio deployment projects ( also not highly regarded and deprecated in the next release of Visual Studio ) do not have native support for services. But they can consume merge modules. So I would take a look at this blog article to understand how to create a merge module using Windows Installer XML that can express the service and then consume that merge module in your VDPROJ solution.

The key is to give the anchor links a display property of "block" and a width property of 100%.

Making list-items clickable (example):

HTML:

<ul>
    <li><a href="">link1</a></li>
    <li><a href="">link2</a></li>
    <li><a href="">link3</a></li>
</ul>

CSS:

ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
}
ul li a {
  display: block;
  width: 100%;
  text-decoration: none;
  padding: 5px;
}
ul li a:hover {
  background-color: #ccc;
}

CPU Virtualization is enabled by default on all MacBooks with compatible CPUs (i7 is compatible). You can try to reset PRAM if you think it was disabled somehow, but I doubt it.

I think the issue might be in the old version of OS. If your MacBook is i7, then you better upgrade OS to something newer.

One more decision with es2015 arrow function

const isBoolean = val => typeof val === 'boolean';

Simple:

if ( $name eq 'tom' && $password eq '123!'
    || $name eq 'frank' && $password eq '321!'
) {

(use the high-precedence && and || in expressions, reserving and and or for flow control, to avoid common precedence errors)

Better:

my %password = (
    'tom' => '123!',
    'frank' => '321!',
);

if ( exists $password{$name} && $password eq $password{$name} ) {

In Python, you can do:

test = float("inf")

In Python 3.5, you can do:

import math
test = math.inf

And then:

test > 1
test > 10000
test > x

Will always be true. Unless of course, as pointed out, x is also infinity or "nan" ("not a number").

Additionally (Python 2.x ONLY), in a comparison to Ellipsis, float(inf) is lesser, e.g:

float('inf') < Ellipsis

would return true.

If you want the output to print to the terminal it is best to use Rscript

Rscript a.R

Note that when using R CMD BATCH a.R that instead of redirecting output to standard out and displaying on the terminal a new file called a.Rout will be created.

R CMD BATCH a.R
# Check the output
cat a.Rout

One other thing to note about using Rscript is that it doesn't load the methods package by default which can cause confusion. So if you're relying on anything that methods provides you'll want to load it explicitly in your script.

If you really want to use the ./a.R way of calling the script you could add an appropriate #! to the top of the script

#!/usr/bin/env Rscript
sayHello <- function(){
   print('hello')
}

sayHello()

I will also note that if you're running on a *unix system there is the useful littler package which provides easy command line piping to R. It may be necessary to use littler to run shiny apps via a script? Further details can be found in this question.

There are mostly all browser support RGBa code in CSS but only IE8 and below level does not support RGBa css code. For This here is solution. For The solution you must follow this code and it’s better to go with it’s sequence otherwise you will not get perfect output as you wish. This code is used by me and it’s mostly perfect. make comment if it’s perfect.

.class
 {
        /* Web browsers that does not support RGBa */
        background: rgb(0, 0, 0);
        /* IE9/FF/chrome/safari supported */
        background: rgba(0, 0, 0, 0.6);
        /* IE 8 suppoerted */
        /* Here some time problem for Hover than you can use background color/image */
        -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#88000000, endColorstr=#88000000)";
        /* Below IE7 supported */
        filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#88000000, endColorstr=#88000000);
 }

Several of the questions/comments I've seen around this subject sound to me as if the person is using Namespace where they mean 'module alias'. As Ryan Cavanaugh mentioned in one of his comments you can have a 'Wrapper' module re-export several modules.

If you really want to import it all from the same module name/alias, combine a wrapper module with a paths mapping in your tsconfig.json.

Example:

./path/to/CompanyName.Products/Foo.ts

export class Foo {
    ...
}

./path/to/CompanyName.Products/Bar.ts

export class Bar {
    ...
}

./path/to/CompanyName.Products/index.ts

export { Foo } from './Foo';
export { Bar } from './Bar';

tsconfig.json

{
    "compilerOptions": {
        ...
        paths: {
            ...
            "CompanyName.Products": ["./path/to/CompanyName.Products/index"],
            ...
        }
        ...
    }
    ...
}

main.ts

import { Foo, Bar } from 'CompanyName.Products'

Note: The module resolution in the output .js files will need to be handled somehow, such as with this https://github.com/tleunen/babel-plugin-module-resolver

Example .babelrc to handle the alias resolution:

{
    "plugins": [
        [ "module-resolver", {
            "cwd": "babelrc",
            "alias": {
                "CompanyName.Products": "./path/to/typescript/build/output/CompanyName.Products/index.js"
            }
        }],
        ... other plugins ...
    ]
}

Generally git pull is enough, but I'm not sure what layout you have chosen (or has github chosen for you).

The first methods seem to work in the browsers that I tested, but the option tags doesn't really correspond to actual elements in all browsers, so the result may vary.

Just use the selectedIndex property of the DOM element:

alert($("#dropDownMenuKategorie")[0].selectedIndex);

Update:

Since version 1.6 jQuery has the prop method that can be used to read properties:

alert($("#dropDownMenuKategorie").prop('selectedIndex'));

This method takes all views inside a layout, this is similar to Alexander Kulyakhtin's answer. The difference is, it accepts any type of parent layouts & returns an Array List of views.

public List<View> getAllViews(ViewGroup layout){
        List<View> views = new ArrayList<>();
        for(int i =0; i< layout.getChildCount(); i++){
            views.add(layout.getChildAt(i));
        }

I'm not sure what your reasons are, and even if you could pull it off somehow with Reflection Emit (I' not sure that you can), it doesn't sound like a good idea. What is probably a better idea is to have some kind of Dictionary and you can wrap access to the dictionary through methods in your class. That way you can store the data from the database in this dictionary, and then retrieve them using those methods.

After hours of searching and looking for answer, finally I made it!!!!! Code is below :))))

HTML:

<form id="fileinfo" enctype="multipart/form-data" method="post" name="fileinfo">
    <label>File to stash:</label>
    <input type="file" name="file" required />
</form>
<input type="button" value="Stash the file!"></input>
<div id="output"></div>

jQuery:

$(function(){
    $('#uploadBTN').on('click', function(){ 
        var fd = new FormData($("#fileinfo"));
        //fd.append("CustomField", "This is some extra data");
        $.ajax({
            url: 'upload.php',  
            type: 'POST',
            data: fd,
            success:function(data){
                $('#output').html(data);
            },
            cache: false,
            contentType: false,
            processData: false
        });
    });
});

In the upload.php file you can access the data passed with $_FILES['file'].

Thanks everyone for trying to help:)

I took the answer from here (with some changes) MDN

Since its mentioned in Android documentation that AAPT has been deprecated, getting the package name using AAPT2 command in Linux is as follows:

./aapt2 dump packagename <path_to_apk>

Since I am using an older version of Gradle build, I had to download a newer version of AAPT2 as mentioned here :

Download AAPT2 from Google Maven

Using the build-tools in my sdk - 25.0.3, 26.0.1 and 27.0.3, executing the aapt2 command shows an error: Unable to open 'packagename': No such file or directory. That's why I went for the newer versions of AAPT2.

I used 3.3.0-5013011 for linux.

If you want to avoid adding extra dependencies, I found node's process.argv to be useful:

gulp.task('mytask', function() {
    console.log(process.argv);
});

So the following:

gulp mytask --option 123

should display:

[ 'node', 'path/to/gulp.js', 'mytask', '--option', '123']

If you are sure that the desired parameter is in the right position, then the flags aren't needed.** Just use (in this case):

var option = process.argv[4]; //set to '123'

BUT: as the option may not be set, or may be in a different position, I feel that a better idea would be something like:

var option, i = process.argv.indexOf("--option");
if(i>-1) {
    option = process.argv[i+1];
}

That way, you can handle variations in multiple options, like:

//task should still find 'option' variable in all cases
gulp mytask --newoption somestuff --option 123
gulp mytask --option 123 --newoption somestuff
gulp mytask --flag --option 123

** Edit: true for node scripts, but gulp interprets anything without a leading "--" as another task name. So using gulp mytask 123 will fail because gulp can't find a task called '123'.

You can just put // in front of $yourUrl in href:

<a href="//<?=$yourUrl?>"></a>

I encountered the same problem when I try to run Ant build using the following command:

java -cp ant.jar:ant-launcher.jar org.apache.tools.ant.Main

The output of the command is:

BUILD FAILED
XXX/build.xml:8: Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "/usr/lib/jvm/java-6-openjdk/jre"

It seems the java executable is picking "/usr/lib/jvm/java-6-openjdk/jre" as JAVA_HOME, as opposed to "/usr/lib/jvm/java-6-openjdk" where JDK is installed.

I resolved this issue by setting fork="yes" in my <javac> task.

Take a look at: http://ant.apache.org/manual/Tasks/javac.html

For domain specific Multi PHP Cron Job, do like this,

/usr/local/bin/ea-php56 /home/username/domain_path/path/to/cron/script

In the above example, replace “ea-php56” with the PHP version assigned to the domain you wish to use.

Hope this helps someone.

You can use a case in this case, to separate versions one example is using FACT os (which returns the version etc of your system... the command facter will return the details:

root@sytem# facter -p os
{"name"=>"CentOS", "family"=>"RedHat", "release"=>{"major"=>"7", "minor"=>"0", "full"=>"7.0.1406"}}

#we capture release hash
$curr_os = $os['release']

case $curr_os['major'] {
  '7': { .... something }
  *: {something}
}

That is an fast example, Might have typos, or not exactly working. But using system facts you can see what happens.

The OS fact provides you 3 main variables: name, family, release... Under release you have a small dictionary with more information about your os! combining these you can create cases to meet your targets.

JUnit 5 and higher

In JUnit 5 you can inject TestInfo which simplifies test meta data providing to test methods. For example:

@Test
@DisplayName("This is my test")
@Tag("It is my tag")
void test1(TestInfo testInfo) {
    assertEquals("This is my test", testInfo.getDisplayName());
    assertTrue(testInfo.getTags().contains("It is my tag"));
}

See more: JUnit 5 User guide, TestInfo javadoc.

Selected answer works for one drop down menu only. For multiple solution would be:

$('body').click(function(event){
   $dropdowns.not($dropdowns.has(event.target)).hide();
});

There is an alternative to using COPY, which is the multirow values syntax that Postgres supports. From the documentation:

INSERT INTO films (code, title, did, date_prod, kind) VALUES
    ('B6717', 'Tampopo', 110, '1985-02-10', 'Comedy'),
    ('HG120', 'The Dinner Game', 140, DEFAULT, 'Comedy');

The above code inserts two rows, but you can extend it arbitrarily, until you hit the maximum number of prepared statement tokens (it might be $999, but I'm not 100% sure about that). Sometimes one cannot use COPY, and this is a worthy replacement for those situations.

I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.

Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled

Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is

1. Remove the XAML for the ad
2. Remove the xmlns declaration (usually at the top of the page, but sometimes will be declared in the ad itself)
3. Remove the bad DLL (the one ending in .SDK )
4. Do a Clean and then Build (clean out anything remaining from the DLL)
5. Add the xmlns reference (actual reference is below)
6. Add the ad to the page (example below)

Here is the xmlns reference:

xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI" 

Then the ad itself:

<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480"                    AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/> 

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

this will work

window.location.assign(window.location.href);

here is an easy way to use join.

''.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

If you don't want the image to affect the layout at all (and float on top of other content) you can apply the following CSS to the image:

position:absolute;
right:0;
top:0;

If you want it to float at the right of a particular parent section, you can add position: relative to that section.

You can use LEN in combination with SUBSTRING:

SELECT SUBSTRING(myColumn, 7, LEN(myColumn)) from myTable

Check if you are returning a @ResponseBody or a @ResponseStatus

I had a similar problem. My Controller looked like that:

@RequestMapping(value="/user", method = RequestMethod.POST)
public String updateUser(@RequestBody User user){
    return userService.updateUser(user).getId();
}

When calling with a POST request I always got the following error:

HTTP Status 405 - Request method 'POST' not supported

After a while I figured out that the method was actually called, but because there is no @ResponseBody and no @ResponseStatus Spring MVC raises the error.

To fix this simply add a @ResponseBody

@RequestMapping(value="/user", method = RequestMethod.POST)
public @ResponseBody String updateUser(@RequestBody User user){
    return userService.updateUser(user).getId();
}

or a @ResponseStatus to your method.

@RequestMapping(value="/user", method = RequestMethod.POST)
@ResponseStatus(value=HttpStatus.OK)
public String updateUser(@RequestBody User user){
    return userService.updateUser(user).getId();
}

You can declare local variables in MySQL triggers, with the DECLARE syntax.

Here's an example:

DROP TABLE IF EXISTS foo;
CREATE TABLE FOO (
  i SERIAL PRIMARY KEY
);

DELIMITER //
DROP TRIGGER IF EXISTS bar //

CREATE TRIGGER bar AFTER INSERT ON foo
FOR EACH ROW BEGIN
  DECLARE x INT;
  SET x = NEW.i;
  SET @a = x; -- set user variable outside trigger
END//

DELIMITER ;

SET @a = 0;

SELECT @a; -- returns 0

INSERT INTO foo () VALUES ();

SELECT @a; -- returns 1, the value it got during the trigger

When you assign a value to a variable, you must ensure that the query returns only a single value, not a set of rows or a set of columns. For instance, if your query returns a single value in practice, it's okay but as soon as it returns more than one row, you get "ERROR 1242: Subquery returns more than 1 row".

You can use LIMIT or MAX() to make sure that the local variable is set to a single value.

CREATE TRIGGER bar AFTER INSERT ON foo
FOR EACH ROW BEGIN
  DECLARE x INT;
  SET x = (SELECT age FROM users WHERE name = 'Bill'); 
  -- ERROR 1242 if more than one row with 'Bill'
END//

CREATE TRIGGER bar AFTER INSERT ON foo
FOR EACH ROW BEGIN
  DECLARE x INT;
  SET x = (SELECT MAX(age) FROM users WHERE name = 'Bill');
  -- OK even when more than one row with 'Bill'
END//

Add:

• DELIMITER at the beginning and end of the SP.
• DROP PROCEDURE IF EXISTS validar_egreso; at the beginning
• When calling the SP, use @variableName.

This works for me. (I modified some part of your script so ANYONE can run it with out having your tables).

DROP PROCEDURE IF EXISTS `validar_egreso`;

DELIMITER $$

CREATE DEFINER='root'@'localhost' PROCEDURE `validar_egreso` (
    IN codigo_producto VARCHAR(100),
    IN cantidad INT,
    OUT valido INT(11)
)
BEGIN

    DECLARE resta INT;
    SET resta = 0;

    SELECT (codigo_producto - cantidad) INTO resta;

    IF(resta > 1) THEN
       SET valido = 1;
    ELSE
       SET valido = -1;
    END IF;

    SELECT valido;
END $$

DELIMITER ;

-- execute the stored procedure
CALL validar_egreso(4, 1, @val);

-- display the result
select @val;

Never try to edit to @_ variable!!!! They must be not touched.. Or you get some unsuspected effect. For example...

my $size=1234;
sub sub1{
  $_[0]=500;
}
sub1 $size;

Before call sub1 $size contain 1234. But after 500(!!) So you Don't edit this value!!! You may pass two or more values and change them in subroutine and all of them will be changed! I've never seen this effect described. Programs I've seen also leave @_ array readonly. And only that you may safely pass variable don't changed internal subroutine You must always do that:

sub sub2{
  my @m=@_;
  ....
}

assign @_ to local subroutine procedure variables and next worked with them. Also in some deep recursive algorithms that returun array you may use this approach to reduce memory used for local vars. Only if return @_ array the same.

You can use HttpClient and HttpPost to build and send the request.

HttpClient client= new DefaultHttpClient();
HttpPost request = new HttpPost("www.example.com");

List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("paramName", "paramValue"));

request.setEntity(new UrlEncodedFormEntity(pairs ));
HttpResponse resp = client.execute(request);

Just my two cents for iOS 10 (under NDA, but for people that can use it legally...)

• Copying full folder (as other people said) works
• Symbolic link seems not.

This was tested using Xcode 7.3 (std from Store) AND iPhone 6Plus with 10.0 (14A5261v).

To avoid the TOCTOU issue highlighted by Éric Araujo's comment, you can catch an exception to call the correct method:

def remove_file_or_dir(path: str) -> None:
    """ Remove a file or directory """
    try:
        shutil.rmtree(path)
    except NotADirectoryError:
        os.remove(path)

Since shutil.rmtree() will only remove directories and os.remove() or os.unlink() will only remove files.

The free and open-source program called cabextract will list and extract the contents of not just .cab-files, but Macrovision's archives too:

% cabextract /tmp/QLWREL.EXE
Extracting cabinet: /tmp/QLWREL.EXE
  extracting ikernel.dll
  extracting IsProBENT.tlb
  ....
  extracting IScript.dll
  extracting iKernel.rgs

All done, no errors.

Use the set() method: see doc

arraylist.set(index,newvalue);

Try:

header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=file.csv");
header("Pragma: no-cache");
header("Expires: 0");

echo "record1,record2,record3\n";
die;

etc

Edit: Here's a snippet of code I use to optionally encode CSV fields:

function maybeEncodeCSVField($string) {
    if(strpos($string, ',') !== false || strpos($string, '"') !== false || strpos($string, "\n") !== false) {
        $string = '"' . str_replace('"', '""', $string) . '"';
    }
    return $string;
}

In response to Haim Evgi's code, I added !== false to the end for it to work for me

$iPod    = stripos($_SERVER['HTTP_USER_AGENT'],"iPod") !== false;
$iPhone  = stripos($_SERVER['HTTP_USER_AGENT'],"iPhone") !== false;
$iPad    = stripos($_SERVER['HTTP_USER_AGENT'],"iPad") !== false;
$Android = stripos($_SERVER['HTTP_USER_AGENT'],"Android") !== false;

This line calls the selector secondMethod after 3 seconds:

[self performSelector:@selector(secondMethod) withObject:nil afterDelay:3.0 ];

Use it on your second operation with your desired delay. If you have a lot of code, place it in its own method and call that method with performSelector:. It wont block the UI like sleep

Edit: If you do not want a second method you could add a category to be able to use blocks with performSelector:

@implementation NSObject (PerformBlockAfterDelay)

- (void)performBlock:(void (^)(void))block 
          afterDelay:(NSTimeInterval)delay
{
    block = [block copy];
    [self performSelector:@selector(fireBlockAfterDelay:) 
               withObject:block 
               afterDelay:delay];
}

- (void)fireBlockAfterDelay:(void (^)(void))block
{
    block();
}

@end

Or perhaps even cleaner:

void RunBlockAfterDelay(NSTimeInterval delay, void (^block)(void))
{
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, NSEC_PER_SEC*delay),
      dispatch_get_current_queue(), block);
}

Convert the image to a byte[] and store that in the database.

Add this column to your model:

public byte[] Content { get; set; }

Then convert your image to a byte array and store that like you would any other data:

public byte[] ImageToByteArray(System.Drawing.Image imageIn)
{
    using(var ms = new MemoryStream())
    {
        imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);

        return ms.ToArray();
    }
}

public Image ByteArrayToImage(byte[] byteArrayIn)
{
     using(var ms = new MemoryStream(byteArrayIn))
     {
         var returnImage = Image.FromStream(ms);

         return returnImage;
     }
}

Source: Fastest way to convert Image to Byte array

var image = new ImageEntity()
{
   Content = ImageToByteArray(image)
};

_context.Images.Add(image);
_context.SaveChanges();

When you want to get the image back, get the byte array from the database and use the ByteArrayToImage and do what you wish with the Image

This stops working when the byte[] gets to big. It will work for files under 100Mb

What is gone is gone. The only protection I know of is regular backup.

I was getting this message while validating (in MVC project). For me, adding ValidationMessageFor element fixed the issue.

To be precise, line number 43 in jquery.validate.unobtrusive.js caused the issue:

  replace = $.parseJSON(container.attr("data-valmsg-replace")) !== false;

When I create a root class, whose methods I defined using the arrow functions. When inheriting and overwriting the original function I noticed the same issue.

class C {
  x = () => 1; 
 };
 
class CC extends C {
  x = (foo) =>  super.x() + foo;
};

let add = new CC;
console.log(add.x(4));

this is solved by defining the method of the parent class without arrow functions

class C {
  x() { 
    return 1; 
  }; 
 };
 
class CC extends C {
  x = foo =>  super.x() + foo;
};

let add = new CC;
console.log(add.x(4));

Example: Inside myWindow() on line 3 is the code you need to set the window in the center of the screen.

JFrame window;

public myWindow() {

    window = new JFrame();
    window.setSize(1200,800);
    window.setLocationRelativeTo(null); // this line set the window in the center of thr screen
    window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    window.getContentPane().setBackground(Color.BLACK);
    window.setLayout(null); // disable the default layout to use custom one.
    window.setVisible(true); // to show the window on the screen.
}

In other words, you want to pipe stdout into one filter (tee bbb.out) and stderr into another filter (tee ccc.out). There is no standard way to pipe anything other than stdout into another command, but you can work around that by juggling file descriptors.

{ { ./aaa.sh | tee bbb.out; } 2>&1 1>&3 | tee ccc.out; } 3>&1 1>&2

See also How to grep standard error stream (stderr)? and When would you use an additional file descriptor?

In bash (and ksh and zsh), but not in other POSIX shells such as dash, you can use process substitution:

./aaa.sh > >(tee bbb.out) 2> >(tee ccc.out)

Beware that in bash, this command returns as soon as ./aaa.sh finishes, even if the tee commands are still executed (ksh and zsh do wait for the subprocesses). This may be a problem if you do something like ./aaa.sh > >(tee bbb.out) 2> >(tee ccc.out); process_logs bbb.out ccc.out. In that case, use file descriptor juggling or ksh/zsh instead.

Since cP/WHM took away the ability to modify User privileges as root in PHPMyAdmin, you have to use the command line to:

mysql>  GRANT FILE ON *.* TO 'user'@'localhost';

Step 2 is to allow that user to dump a file in a specific folder. There are a few ways to do this but I ended up putting a folder in :

/home/user/tmp/db

and

chown mysql:mysql /home/user/tmp/db

That allows the mysql user to write the file. As previous posters have said, you can use the MySQL temp folder too, I don't suppose it really matters but you definitely don't want to make it 0777 permission (world-writeable) unless you want the world to see your data. There is a potential problem if you want to rinse-repeat the process as INTO OUTFILE won't work if the file exists. If your files are owned by a different user then just trying to unlink($file) won't work. If you're like me (paranoid about 0777) then you can set your target directory using:

chmod($dir,0777)

just prior to doing the SQL command, then

chmod($dir,0755)

immediately after, followed by unlink(file) to delete the file. This keeps it all running under your web user and no need to invoke the mysql user.

In SQL Server 2008, you can use:

CONVERT(DATE, getdate(), 101)

Implementing the SearchView without the use of the menu.xml file and open through button

In your Activity we need to use the method of the onCreateOptionsMenumethod in which we will programmatically inflate the SearchView

private MenuItem searchMenu;
private String mSearchString="";

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);

        SearchManager searchManager = (SearchManager) StoreActivity.this.getSystemService(Context.SEARCH_SERVICE);


        SearchView mSearchView = new SearchView(getSupportActionBar().getThemedContext());
        mSearchView.setQueryHint(getString(R.string.prompt_search)); /// YOUR HINT MESSAGE
        mSearchView.setMaxWidth(Integer.MAX_VALUE);

        searchMenu = menu.add("searchMenu").setVisible(false).setActionView(mSearchView);
        searchMenu.setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);


        assert searchManager != null;
        mSearchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
        mSearchView.setIconifiedByDefault(false);

        SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() {
            public boolean onQueryTextChange(String newText) {
                mSearchString = newText;

                return true;
            }

            public boolean onQueryTextSubmit(String query) {
                mSearchString = query;

                searchMenu.collapseActionView();


                return true;
            }
        };

        mSearchView.setOnQueryTextListener(queryTextListener);


        return true;
    }

And in your Activity class, you can open the SearchView on any button click on toolbar like below

YOUR_BUTTON.setOnClickListener(view -> {

            searchMenu.expandActionView();

Maybe you were trying to do this?

int func(int * B){

    /* B + OFFSET = 5 () You are pointing to the same region as B[OFFSET] */
    *(B + 2) = 5;
}

int main(void) {

    int B[10];

    func(B);

    /* Let's say you edited only 2 and you want to show it. */
    printf("b[0] = %d\n\n", B[2]);

    return 0;

This is clearly a problem that a lot of programmers have and to which Google has yet to provide a satisfactory, supported solution.

There are a lot of crossed intentions and misunderstandings floating around posts on this topic, so please read this whole answer before responding.

Below I include a more "refined" and well-commented version of the hack from other answers on this page, also incorporating ideas from these very closely related questions:

Change background color of android menu

How to change the background color of the options menu?

Android: customize application's menu (e.g background color)

http://www.macadamian.com/blog/post/android_-_theming_the_unthemable/

Android MenuItem Toggle Button

Is it possible to make the Android options menu background non-translucent?

http://www.codeproject.com/KB/android/AndroidMenusMyWay.aspx

Setting the menu background to be opaque

I tested this hack on 2.1 (simulator), 2.2 (2 real devices), and 2.3 (2 real devices). I don't have any 3.X tablets to test on yet but will post any needed changes here when/if I do. Given that 3.X tablets use Action Bars instead of Options Menus, as explained here:

http://developer.android.com/guide/topics/ui/menus.html#options-menu

this hack will almost certainly do nothing (no harm and no good) on 3.X tablets.

STATEMENT OF THE PROBLEM (read this before trigger-replying with a negative comment):

The Options menu has vastly different styles on different devices. Pure black with white text on some, pure white with black text on some. I and many other developers wish to control the background color of the Options menu cells as well as the color of the Options menu text.

Certain app developers only need to set the cell background color (not the text color), and they can do this in a cleaner manner using the android:panelFullBackground style described in another answer. However, there is currently no way to control the Options menu text color with styles, and so one can only use this method to change the background to another color that won't make the text "disappear."

We would love to do this with a documented, future-proof solution, but one is simply not available as of Android <= 2.3. So we have to use a solution that works in current versions and is designed to minimize the chances of crashing/breaking in future versions. We want a solution that fails gracefully back to the default behavior if it has to fail.

There are many legitimate reasons why one may need to control the look of Options menus (typically to match a visual style for the rest of the app) so I won't dwell on that.

There is a Google Android bug posted about this: please add your support by starring this bug (note Google discourages "me too" comments: just a star is enough):

http://code.google.com/p/android/issues/detail?id=4441

SUMMARY OF SOLUTIONS SO FAR:

Several posters have suggested a hack involving LayoutInflater.Factory. The suggested hack worked for Android <= 2.2 and failed for Android 2.3 because the hack made an undocumented assumption: that one could call LayoutInflater.getView() directly without currently being inside a call to LayoutInflater.inflate() on the same LayoutInflater instance. New code in Android 2.3 broke this assumption and led to a NullPointerException.

My slightly refined hack below does not rely on this assumption.

Furthermore, the hacks also rely on using an internal, undocumented class name "com.android.internal.view.menu.IconMenuItemView" as a string (not as a Java type). I do not see any way to avoid this and still accomplish the stated goal. However, it is possible to do the hack in a careful way that will fall back if "com.android.internal.view.menu.IconMenuItemView" does not appear on the current system.

Again, understand that this is a hack and by no means am I claiming this will work on all platforms. But we developers are not living in a fantasy academic world where everything has to be by the book: we have a problem to solve and we have to solve it as best we can. For example, it seems unlikely that "com.android.internal.view.menu.IconMenuItemView" will exist on 3.X tablets since they use Action Bars instead of Options Menus.

Finally, some developers have solved this problem by totally suppressing the Android Options Menu and writing their own menu class (see some of the links above). I haven't tried this, but if you have time to write your own View and figure out how to replace Android's view (I'm sure the devil's in the details here) then it might be a nice solution that doesn't require any undocumented hacks.

HACK:

Here is the code.

To use this code, call addOptionsMenuHackerInflaterFactory() ONCE from your activity onCreate() or your activity onCreateOptionsMenu(). It sets a default factory that will affect subsequent creation of any Options Menu. It does not affect Options Menus that have already been created (the previous hacks used a function name of setMenuBackground(), which is very misleading since the function doesn't set any menu properties before it returns).

@SuppressWarnings("rawtypes")
static Class       IconMenuItemView_class = null;
@SuppressWarnings("rawtypes")
static Constructor IconMenuItemView_constructor = null;

// standard signature of constructor expected by inflater of all View classes
@SuppressWarnings("rawtypes")
private static final Class[] standard_inflater_constructor_signature = 
new Class[] { Context.class, AttributeSet.class };

protected void addOptionsMenuHackerInflaterFactory()
{
    final LayoutInflater infl = getLayoutInflater();

    infl.setFactory(new Factory()
    {
        public View onCreateView(final String name, 
                                 final Context context,

        {
            if (!name.equalsIgnoreCase("com.android.internal.view.menu.IconMenuItemView"))
                return null; // use normal inflater

            View view = null;

            // "com.android.internal.view.menu.IconMenuItemView"

            // - unfortunately we cannot just call:

            //   here because on Android 3.2 (and possibly later):
            //   1. createView() can only be called inside inflate(),

            //      passed to the IconMenuItemView constructor's first arg,
            //      storing it in a LayoutInflater instance variable.
            //   2. we are inside inflate(),
            //   3. BUT from a different instance of LayoutInflater (not infl)
            //   4. there is no way to get access to the actual instance being used

You can change target for Git Bash shortcut from:

"C:\Program Files\Git\git-bash.exe" --cd-to-home 

to

"C:\Program Files\Git\git-cmd.exe" --no-cd --command=usr/bin/bash.exe -l -i

This is the way ConEmu used to start git bash (version 16). Recent version starts it normally and it's how I got there...

This is kind of a hack but the best solution that I have found is to use a description tag with no \item. This will produce an error from the latex compiler; however, the error does not prevent the pdf from being generated.

\begin{description} 
     <YOUR TEXT HERE> 
\end{description}

• This only worked on windows latex compiler

Choose one from, where :my_date is a string input parameter of yyyy-MM-dd format:

SELECT EXTRACT(YEAR FROM CAST(:my_date AS DATE));

or

SELECT DATE_PART('year', CAST(:my_date AS DATE));

Better use CAST than :: as there may be conflicts with input parameters.

You can use this utility:

c:\Windows\system32\fsutil.exe create hardlink

ex: url/:id

var sample= app.controller('sample', function ($scope, $routeParams) {
  $scope.init = function () {
    var qa_id = $routeParams.qa_id;
  }
});

To see exactly what is happening, use nc -l or an ECHO server and an user agent like a browser or cURL.

Save the form to an .html file:

<form action="http://localhost:8000" method="post" enctype="multipart/form-data">
  <p><input type="text" name="text" value="text default">
  <p><input type="file" name="file1">
  <p><input type="file" name="file2">
  <p><button type="submit">Submit</button>
</form>

Create files to upload:

echo 'Content of a.txt.' > a.txt
echo '<!DOCTYPE html><title>Content of a.html.</title>' > a.html

Run:

nc -l localhost 8000

Open the HTML on your browser, select the files and click on submit and check the terminal.

nc prints the request received. Firefox sent:

Use CURRENT_TIMESTAMP (or GETDATE() on archaic versions of SQL Server).

Pulling may have created local change.

Add your untracked file:

git add .

Stash changes.

git stash

Drop local changes.

git stash drop

Pull with sudo permission

sudo git pull remote branch

You can use following code for that:

var assignedRoleId = new Array();
$('#RolesListAssigned option').each(function(){
    assignedRoleId.push(this.value);
});

If you declare the name for enumeration no error will occur.

If not declared, you have to use a typedef:

enum enum_name {RANDOM, IMMEDIATE, SEARCH} strategy;
strategy = IMMEDIATE;

It will not display an error...

The linked list holds operations on the shared data structure.

For example, if I have a stack, it will be manipulated with pushes and pops. The linked list would be a set of pushes and pops on the pseudo-shared stack. Each thread sharing that stack will actually have a local copy, and to get to the current shared state, it'll walk the linked list of operations, and apply each operation in order to its local copy of the stack. When it reaches the end of the linked list, its local copy holds the current state (though, of course, it's subject to becoming stale at any time).

In the traditional model, you'd have some sort of locks around each push and pop. Each thread would wait to obtain a lock, then do a push or pop, then release the lock.

In this model, each thread has a local snapshot of the stack, which it keeps synchronized with other threads' view of the stack by applying the operations in the linked list. When it wants to manipulate the stack, it doesn't try to manipulate it directly at all. Instead, it simply adds its push or pop operation to the linked list, so all the other threads can/will see that operation and they can all stay in sync. Then, of course, it applies the operations in the linked list, and when (for example) there's a pop it checks which thread asked for the pop. It uses the popped item if and only if it's the thread that requested this particular pop.

Use the Microsoft.VisualBasic.FileIO.TextFieldParser class. This will handle parsing a delimited file, TextReader or Stream where some fields are enclosed in quotes and some are not.

For example:

using Microsoft.VisualBasic.FileIO;

string csv = "2,1016,7/31/2008 14:22,Geoff Dalgas,6/5/2011 22:21,http://stackoverflow.com,\"Corvallis, OR\",7679,351,81,b437f461b3fd27387c5d8ab47a293d35,34";

TextFieldParser parser = new TextFieldParser(new StringReader(csv));

// You can also read from a file
// TextFieldParser parser = new TextFieldParser("mycsvfile.csv");

parser.HasFieldsEnclosedInQuotes = true;
parser.SetDelimiters(",");

string[] fields;

while (!parser.EndOfData)
{
    fields = parser.ReadFields();
    foreach (string field in fields)
    {
        Console.WriteLine(field);
    }
} 

parser.Close();

This should result in the following output:

See Microsoft.VisualBasic.FileIO.TextFieldParser for more information.

You need to add a reference to Microsoft.VisualBasic in the Add References .NET tab.

First, you should know what an Optional value is. You can step to The Swift Programming Language for detail.

Second, you should know the optional value has two statuses. One is the full value, and the other is a nil value. So before you implement an optional value, you should check which state it is.

You can use if let ... or guard let ... else and so on.

One other way, if you don't want to check the variable state before your implementation, you can also use var buildingName = buildingName ?? "buildingName" instead.

Additionally for what was said, if you want integer powers of two, then 1 << x (or 1L << x) is a faster way to calculate 2^x than Math.pow(2,x) or a multiplication loop, and is guaranteed to give you an int (or long) result.

It only uses the lowest 5 (or 6) bits of x (i.e. x & 31 (or x & 63)), though, shifting between 0 and 31 (or 63) bits.

router.use(function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Methods", "*");
res.header("Access-Control-Allow-Headers", "*");
next();});

add this to your routes which you are calling from front-end. Ex- if you call for http://localhost:3000/users/register you must add this code fragment on your back-end .js file which this route lays.

In my case, when I'm in an activity that extends from AppCompatActivity, it did not work(Activity) getApplicationContext (), I just putthis in its place.

Or far simpler than dealing with Spannables manually, since you didn't say that you want the background highlighted, just the text:

String styledText = "This is <font color='red'>simple</font>.";

Often when you need to show so many points on the map, you'd be better off using the server-side approach, this article explains when to use each:

Geocoding Strategies: https://developers.google.com/maps/articles/geocodestrat

The client-side limit is not exactly "10 requests per second", and since it's not explained in the API docs I wouldn't rely on its behavior.

Actually Shay levy's answer is almost correct but i got an weird issue as i mentioned in his comment column. So i split the command into two lines and it works fine.

$Ipaddress= Read-Host "Enter the IP address:"
$Port= Read-host "Enter the port number to access:"

$t = New-Object Net.Sockets.TcpClient
$t.Connect($Ipaddress,$Port)
    if($t.Connected)
    {
        "Port $Port is operational"
    }
    else
    {
        "Port $Port is closed, You may need to contact your IT team to open it. "
    }

If you need to just empty the style of an element then:
element.style.cssText = null;
This should do good. Hope it helps!

Same solution as @Al3x for Windows x64, in cmd.exe:

cd %programfiles%\Oracle\VirtualBox

VBoxManage internalcommands sethduuid "full/path/to/.vdi"

This randomizes the UUID of the disk. Pro tip: Right click the .vdi file while holding shift and select "Copy as path" to obtain "full/path/to/.vdi" and enable quick edit in cmd.exe, then right click to paste.

I've used this "portable plotter". It's very small, multiplatform, easy to use and you can plug it into different graphical libraries. pplot

(Only for the plots part)

If you use or plan to use Qt, another multiplatform solution is Qwt and Qchart

If you have multiple inputs as text in a form or a table that you need to iterate through, I did this:

var $list = $("#tableOrForm :input[type='text']");

$list.each(function(){
    // Go on with your code.
});

What I did was I checked each input to see if the type is set to "text", then it'll grab that element and store it in the jQuery list. Then, it would iterate through that list. You can set a temp variable for the current iteration like this:

var $currentItem = $(this);

This will set the current item to the current iteration of your for each loop. Then you can do whatever you want with the temp variable.

Hope this helps anyone!

This is a common question in C++ programming. There are two valid answers to this. There are advantages and disadvantages to both answers and your choice will depend on context. The common answer is to put all the implementation in the header file, but there's another approach will will be suitable in some cases. The choice is yours.

The code in a template is merely a 'pattern' known to the compiler. The compiler won't compile the constructors cola<float>::cola(...) and cola<string>::cola(...) until it is forced to do so. And we must ensure that this compilation happens for the constructors at least once in the entire compilation process, or we will get the 'undefined reference' error. (This applies to the other methods of cola<T> also.)

Understanding the problem

The problem is caused by the fact that main.cpp and cola.cpp will be compiled separately first. In main.cpp, the compiler will implicitly instantiate the template classes cola<float> and cola<string> because those particular instantiations are used in main.cpp. The bad news is that the implementations of those member functions are not in main.cpp, nor in any header file included in main.cpp, and therefore the compiler can't include complete versions of those functions in main.o. When compiling cola.cpp, the compiler won't compile those instantiations either, because there are no implicit or explicit instantiations of cola<float> or cola<string>. Remember, when compiling cola.cpp, the compiler has no clue which instantiations will be needed; and we can't expect it to compile for every type in order to ensure this problem never happens! (cola<int>, cola<char>, cola<ostream>, cola< cola<int> > ... and so on ...)

The two answers are:

• Tell the compiler, at the end of cola.cpp, which particular template classes will be required, forcing it to compile cola<float> and cola<string>.
• Put the implementation of the member functions in a header file that will be included every time any other 'translation unit' (such as main.cpp) uses the template class.

Answer 1: Explicitly instantiate the template, and its member definitions

At the end of cola.cpp, you should add lines explicitly instantiating all the relevant templates, such as

template class cola<float>;
template class cola<string>;

and you add the following two lines at the end of nodo_colaypila.cpp:

template class nodo_colaypila<float>;
template class nodo_colaypila<std :: string>;

This will ensure that, when the compiler is compiling cola.cpp that it will explicitly compile all the code for the cola<float> and cola<string> classes. Similarly, nodo_colaypila.cpp contains the implementations of the nodo_colaypila<...> classes.

In this approach, you should ensure that all the of the implementation is placed into one .cpp file (i.e. one translation unit) and that the explicit instantation is placed after the definition of all the functions (i.e. at the end of the file).

Answer 2: Copy the code into the relevant header file

The common answer is to move all the code from the implementation files cola.cpp and nodo_colaypila.cpp into cola.h and nodo_colaypila.h. In the long run, this is more flexible as it means you can use extra instantiations (e.g. cola<char>) without any more work. But it could mean the same functions are compiled many times, once in each translation unit. This is not a big problem, as the linker will correctly ignore the duplicate implementations. But it might slow down the compilation a little.

Summary

The default answer, used by the STL for example and in most of the code that any of us will write, is to put all the implementations in the header files. But in a more private project, you will have more knowledge and control of which particular template classes will be instantiated. In fact, this 'bug' might be seen as a feature, as it stops users of your code from accidentally using instantiations you have not tested for or planned for ("I know this works for cola<float> and cola<string>, if you want to use something else, tell me first and will can verify it works before enabling it.").

Finally, there are three other minor typos in the code in your question:

• You are missing an #endif at the end of nodo_colaypila.h
• in cola.h nodo_colaypila<T>* ult, pri; should be nodo_colaypila<T> *ult, *pri; - both are pointers.
• nodo_colaypila.cpp: The default parameter should be in the header file nodo_colaypila.h, not in this implementation file.

This helps for HTML5 SQLite:

tx.executeSql('SELECT name, sql FROM sqlite_master WHERE type="table" AND name = "your_table_name";', [], function (tx, results) {
  var columnParts = results.rows.item(0).sql.replace(/^[^\(]+\(([^\)]+)\)/g, '$1').split(','); ///// RegEx
  var columnNames = [];
  for(i in columnParts) {
    if(typeof columnParts[i] === 'string')
      columnNames.push(columnParts[i].split(" ")[0]);
  }
  console.log(columnNames);
  ///// Your code which uses the columnNames;
});

You can reuse the regex in your language to get the column names.

Shorter Alternative:

tx.executeSql('SELECT name, sql FROM sqlite_master WHERE type="table" AND name = "your_table_name";', [], function (tx, results) {
  var columnNames = results.rows.item(0).sql.replace(/^[^\(]+\(([^\)]+)\)/g, '$1').replace(/ [^,]+/g, '').split(',');
  console.log(columnNames);
  ///// Your code which uses the columnNames;
});

Because userString is empty. You only declare it

vector<string> userString;     

but never add anything, so the for loop won't even run.

Furthermore, you also have || which is the logical or, and also ; which is just a separator which doesn't care what happend to the command before.

$ false || echo "Oops, fail"
Oops, fail

$ true || echo "Will not be printed"
$  

$ true && echo "Things went well"
Things went well

$ false && echo "Will not be printed"
$

$ false ; echo "This will always run"
This will always run

Some details about this can be found here Lists of Commands in the Bash Manual.

Try something like this... jsfiddle demo

HTML

<!-- Source: -->
<select id="source" name="source">
     <option>MANUAL</option>
     <option>ONLINE</option>
</select>

<!-- Status: -->
<select id="status" name="status">
    <option>OPEN</option>
    <option>DELIVERED</option>
</select>

JS

$(document).ready(function () {

    $("#source").change(function () {
        var el = $(this);
        if (el.val() === "ONLINE") {
            $("#status").append("<option>SHIPPED</option>");
        } else if (el.val() === "MANUAL") {
            $("#status option:last-child").remove();
        }
    });

});

Before proceeding, ensure that you: Have completed a full database backup!

Step 1: Database Level Changes

• Identifying the Collation and Character set of your database

  SELECT DEFAULT_CHARACTER_SET_NAME, DEFAULT_COLLATION_NAME FROM 
  information_schema.SCHEMATA S
  WHERE schema_name = 'your_database_name'
  AND
  (DEFAULT_CHARACTER_SET_NAME != 'utf8'
      OR
   DEFAULT_COLLATION_NAME not like 'utf8%');
  

• Fixing the collation for the database

  ALTER DATABASE databasename CHARACTER SET utf8 COLLATE utf8_unicode_ci;
  

Step 2: Table Level Changes

• Identifying Database Tables with the incorrect character set or collation

  SELECT CONCAT(
  'ALTER TABLE ',  table_name, ' CHARACTER SET utf8 COLLATE utf8_general_ci;  ', 
  'ALTER TABLE ',  table_name, ' CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;  ')
  FROM information_schema.TABLES AS T, information_schema.`COLLATION_CHARACTER_SET_APPLICABILITY` AS C
  WHERE C.collation_name = T.table_collation
  AND T.table_schema = 'your_database_name'
  AND
  (C.CHARACTER_SET_NAME != 'utf8'
      OR
   C.COLLATION_NAME not like 'utf8%')
  

• Adjusting table columns' collation and character set

Capture upper sql output and run it. (like following)

ALTER TABLE rma CHARACTER SET utf8 COLLATE utf8_general_ci;ALTER TABLE rma CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;  
ALTER TABLE rma_history CHARACTER SET utf8 COLLATE utf8_general_ci;ALTER TABLE rma_history CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;  
ALTER TABLE rma_products CHARACTER SET utf8 COLLATE utf8_general_ci;ALTER TABLE rma_products CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;  
ALTER TABLE rma_report_period CHARACTER SET utf8 COLLATE utf8_general_ci;ALTER TABLE rma_report_period CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;  
ALTER TABLE rma_reservation CHARACTER SET utf8 COLLATE utf8_general_ci;ALTER TABLE rma_reservation CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;  
ALTER TABLE rma_supplier_return CHARACTER SET utf8 COLLATE utf8_general_ci;ALTER TABLE rma_supplier_return CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;  
ALTER TABLE rma_supplier_return_history CHARACTER SET utf8 COLLATE utf8_general_ci;ALTER TABLE rma_supplier_return_history CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;  
ALTER TABLE rma_supplier_return_product CHARACTER SET utf8 COLLATE utf8_general_ci;ALTER TABLE rma_supplier_return_product CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;

const tifOptions = [];

for (const [key, value] of Object.entries(tifs)) {
    tifOptions.push(<option value={key} key={key}>{value}</option>);

return (
   <select id="tif" name="tif" onChange={this.handleChange}>  
      { tifOptions }

Since the value of $var is the empty string, this:

if [ $var == $var1 ]; then

expands to this:

if [ == abcd ]; then

which is a syntax error.

You need to quote the arguments:

if [ "$var" == "$var1" ]; then

You can also use = rather than ==; that's the original syntax, and it's a bit more portable.

If you're using bash, you can use the [[ syntax, which doesn't require the quotes:

if [[ $var = $var1 ]]; then

Even then, it doesn't hurt to quote the variable reference, and adding quotes:

if [[ "$var" = "$var1" ]]; then

might save a future reader a moment trying to remember whether [[ ... ]] requires them.

PHP will work only on the .php file extension.

If you are on Apache you can also set, in your httpd.conf file, the extensions for PHP. You'll have to find the line:

AddType application/x-httpd-php .php .html
                                     ^^^^^

and add how many extensions, that should be read with the PHP interpreter, as you want.
