Programs & Examples On #Filecontentresult

public FileContentResult GetImage(int productId) { 
     Product prod = repository.Products.FirstOrDefault(p => p.ProductID == productId); 
     if (prod != null) { 
         return File(prod.ImageData, prod.ImageMimeType);

Use this query this will give your output:

select 
  t.name
  ,( select 
       count (*) as num_value 
     from Table 
      where num =t.num) cnt 
from Table t;

you can use

console.clear();

if you are working with javascript coding.

else you can use CTR+L to clear cosole editor.

Step 1) Remove the semi-colon, it's an object you're creating...

a(this).next().css({
    left       : c,
    transition : 'opacity 1s ease-in-out';
});

to

a(this).next().css({
    left       : c,
    transition : 'opacity 1s ease-in-out'
});

Step 2) Vendor-prefixes... no browsers use transition since it's the standard and this is an experimental feature even in the latest browsers:

a(this).next().css({
    left             : c,
    WebkitTransition : 'opacity 1s ease-in-out',
    MozTransition    : 'opacity 1s ease-in-out',
    MsTransition     : 'opacity 1s ease-in-out',
    OTransition      : 'opacity 1s ease-in-out',
    transition       : 'opacity 1s ease-in-out'
});

Here is a demo: http://jsfiddle.net/83FsJ/

Step 3) Better vendor-prefixes... Instead of adding tons of unnecessary CSS to elements (that will just be ignored by the browser) you can use jQuery to decide what vendor-prefix to use:

$('a').on('click', function () {
    var myTransition = ($.browser.webkit)  ? '-webkit-transition' :
                       ($.browser.mozilla) ? '-moz-transition' : 
                       ($.browser.msie)    ? '-ms-transition' :
                       ($.browser.opera)   ? '-o-transition' : 'transition',
        myCSSObj     = { opacity : 1 };

    myCSSObj[myTransition] = 'opacity 1s ease-in-out';
    $(this).next().css(myCSSObj);
});?

Here is a demo: http://jsfiddle.net/83FsJ/1/

Also note that if you specify in your transition declaration that the property to animate is opacity, setting a left property won't be animated.

You can also use pandas.Series.isin although it's a little bit longer than 'a' in s.values:

In [2]: s = pd.Series(list('abc'))

In [3]: s
Out[3]: 
0    a
1    b
2    c
dtype: object

In [3]: s.isin(['a'])
Out[3]: 
0    True
1    False
2    False
dtype: bool

In [4]: s[s.isin(['a'])].empty
Out[4]: False

In [5]: s[s.isin(['z'])].empty
Out[5]: True

But this approach can be more flexible if you need to match multiple values at once for a DataFrame (see DataFrame.isin)

>>> df = DataFrame({'A': [1, 2, 3], 'B': [1, 4, 7]})
>>> df.isin({'A': [1, 3], 'B': [4, 7, 12]})
       A      B
0   True  False  # Note that B didn't match 1 here.
1  False   True
2   True   True

It is caused by a lack of precision with doubles / decimals (i.e. - the function will not always give the result you expect).

See the following link: MSDN on Math.Round

Here is the relevant quote:

Because of the loss of precision that can result from representing decimal values as floating-point numbers or performing arithmetic operations on floating-point values, in some cases the Round(Double, Int32, MidpointRounding) method may not appear to round midpoint values as specified by the mode parameter.This is illustrated in the following example, where 2.135 is rounded to 2.13 instead of 2.14.This occurs because internally the method multiplies value by 10digits, and the multiplication operation in this case suffers from a loss of precision.

I tried to add the following options in the /etc/docker/daemon.json. (I used CentOS7)

"add-registry": ["192.168.100.100:5001"],
"block-registry": ["docker.io"],

after that, restarted docker daemon. And it's working without docker.io. I hope this someone will be helpful.

Why would you want to do this? You shouldn't be executing controller code in the view, and most certainly shouldn't be trying to pull code inside of another servlet into the view either.

Do all of your processing and refactoring of the application first, then just pass off the results to a view. Make the view as dumb as possible and you won't even run into these problems.

If this kind of design is hard for you, try Freemarker or even something like Velocity (although I don't recommend it) to FORCE you to do this. You never have to do this sort of thing ever.

To put it more accurately, the problem you are trying to solve is just a symptom of a greater problem - your architecture/design of your servlets.

You can regroup your steps functions calls in a facade function :

sub facade()
    call step1()
    call step2()
    call step3()
    call step4()
    call step5()
end sub

Then, let your error handling be in an upper function that calls the facade :

sub main()
    On error resume next

    call facade()

    If Err.Number <> 0 Then
        ' MsgBox or whatever. You may want to display or log your error there
        msgbox Err.Description
        Err.Clear
    End If

    On Error Goto 0
end sub

Now, let's suppose step3() raises an error. Since facade() doesn't handle errors (there is no On error resume next in facade()), the error will be returned to main() and step4() and step5() won't be executed.

Your error handling is now refactored in 1 code block

In my case there was a corrupted character in one of the named params ("-StorageAccountName" for cmdlet "Get-AzureStorageKey") which showed as perfectly normal in my editor (SublimeText) but Windows Powershell couldn't parse it.

To get to the bottom of it, I moved the offending lines from the error message into another .ps1 file, ran that, and the error now showed a botched character at the beginning of my "-StorageAccountName" parameter.

Deleting the character (again which looks normal in the actual editor) and re-typing it fixes this issue.

1. exec is not an expression: a statement in Python 2.x, and a function in Python 3.x. It compiles and immediately evaluates a statement or set of statement contained in a string. Example:

    exec('print(5)')           # prints 5.
    # exec 'print 5'     if you use Python 2.x, nor the exec neither the print is a function there
    exec('print(5)\nprint(6)')  # prints 5{newline}6.
    exec('if True: print(6)')  # prints 6.
    exec('5')                 # does nothing and returns nothing.
   

2. eval is a built-in function (not a statement), which evaluates an expression and returns the value that expression produces. Example:

    x = eval('5')              # x <- 5
    x = eval('%d + 6' % x)     # x <- 11
    x = eval('abs(%d)' % -100) # x <- 100
    x = eval('x = 5')          # INVALID; assignment is not an expression.
    x = eval('if 1: x = 4')    # INVALID; if is a statement, not an expression.
   

3. compile is a lower level version of exec and eval. It does not execute or evaluate your statements or expressions, but returns a code object that can do it. The modes are as follows:

4. compile(string, '', 'eval') returns the code object that would have been executed had you done eval(string). Note that you cannot use statements in this mode; only a (single) expression is valid.

5. compile(string, '', 'exec') returns the code object that would have been executed had you done exec(string). You can use any number of statements here.

6. compile(string, '', 'single') is like the exec mode but expects exactly one expression/statement, eg compile('a=1 if 1 else 3', 'myf', mode='single')

First of all we should get clear that Hadoop was created as a faster alternative to RDBMS. To process large amount of data at a very fast rate which earlier took a lot of time in RDBMS.

Now one should know the two terms :

1. Structured Data : This is the data that we used in traditional RDBMS and is divided into well defined structures.

2. Unstructured Data : This is important to understand, about 80% of the world data is unstructured or semi structured. These are the data which are on its raw form and cannot be processed using RDMS. Example : facebook, twitter data. (http://www.dummies.com/how-to/content/unstructured-data-in-a-big-data-environment.html).

So, large amount of data was being generated in the last few years and the data was mostly unstructured, that gave birth to HADOOP. It was mainly used for very large amount of data that takes unfeasible amount of time using RDBMS. It had many drawbacks, that it could not be used for comparatively small data in real time but they have managed to remove its drawbacks in the newer version.

Before going further I would like to tell that a new Big Data tool is created when they see a fault on the previous tools. So, whichever tool you will see that is created has been done to overcome the problem of the previous tools.

Hadoop can be simply said as two things : Mapreduce and HDFS. Mapreduce is where the processing takes place and HDFS is the DataBase where data is stored. This structure followed WORM principal i.e. write once read multiple times. So, once we have stored data in HDFS, we cannot make changes. This led to the creation of HBASE, a NOSQL product where we can make changes in the data also after writing it once.

But with time we saw that Hadoop had many faults and for that we created different environment over the Hadoop structure. PIG and HIVE are two popular examples.

HIVE was created for people with SQL background. The queries written is similar to SQL named as HIVEQL. HIVE was developed to process completely structured data. It is not used for ustructured data.

PIG on the other hand has its own query language i.e. PIG LATIN. It can be used for both structured as well as unstructured data.

Moving to the difference as when to use HIVE and when to use PIG, I don't think anyone other than the architect of PIG could say. Follow the link : https://developer.yahoo.com/blogs/hadoop/comparing-pig-latin-sql-constructing-data-processing-pipelines-444.html

The problem you run into when setting width to 50% is the rounding of subpixels. If the width of your container is i.e. 99 pixels, a width of 50% can result in 2 containers of 50 pixels each.

Using float is probably easiest, and not such a bad idea. See this question for more details on how to fix the problem then.

If you don't want to use float, try using a width of 49%. This will work cross-browser as far as I know, but is not pixel-perfect..

html:

<div id="a">A</div>
<div id="b">B</div>

css:

#a, #b {
    width: 49%;
    display: inline-block; 
}
#a {background-color: red;}
#b {background-color: blue;}

Comparing non-primitives (aka Objects) in Java with == compares their reference instead of their values. Long is a class and thus Long values are Objects.

The problem is that the Java Developers wanted people to use Long like they used long to provide compatibility, which led to the concept of autoboxing, which is essentially the feature, that long-values will be changed to Long-Objects and vice versa as needed. The behaviour of autoboxing is not exactly predictable all the time though, as it is not completely specified.

So to be safe and to have predictable results always use .equals() to compare objects and do not rely on autoboxing in this case:

Long num1 = 127, num2 = 127;
if(num1.equals(num2)) { iWillBeExecutedAlways(); }

public static string ToFormattedCurrencyString(
    this decimal currencyAmount,
    string isoCurrencyCode,
    CultureInfo userCulture)
{
    var userCurrencyCode = new RegionInfo(userCulture.Name).ISOCurrencySymbol;

if (userCurrencyCode == isoCurrencyCode)
{
    return currencyAmount.ToString("C", userCulture);
}

return string.Format(
    "{0} {1}", 
    isoCurrencyCode, 
    currencyAmount.ToString("N2", userCulture));

}

There are a number of different solutions for finding running median from streamed data, I will briefly talk about them at the very end of the answer.

The question is about the details of the a specific solution (max heap/min heap solution), and how heap based solution works is explained below:

For the first two elements add smaller one to the maxHeap on the left, and bigger one to the minHeap on the right. Then process stream data one by one,

Step 1: Add next item to one of the heaps

   if next item is smaller than maxHeap root add it to maxHeap,
   else add it to minHeap

Step 2: Balance the heaps (after this step heaps will be either balanced or
   one of them will contain 1 more item)

   if number of elements in one of the heaps is greater than the other by
   more than 1, remove the root element from the one containing more elements and
   add to the other one

Then at any given time you can calculate median like this:

   If the heaps contain equal amount of elements;
     median = (root of maxHeap + root of minHeap)/2
   Else
     median = root of the heap with more elements

Now I will talk about the problem in general as promised in the beginning of the answer. Finding running median from a stream of data is a tough problem, and finding an exact solution with memory constraints efficiently is probably impossible for the general case. On the other hand, if the data has some characteristics we can exploit, we can develop efficient specialized solutions. For example, if we know that the data is an integral type, then we can use counting sort, which can give you a constant memory constant time algorithm. Heap based solution is a more general solution because it can be used for other data types (doubles) as well. And finally, if the exact median is not required and an approximation is enough, you can just try to estimate a probability density function for the data and estimate median using that.

When looking at an input with a type of number, you'll notice the spinner buttons (up/down) on the right-hand side of the input field. These spinners aren't always desirable, thus the code below removes such styling to render an input that resembles that of an input with a type of text.

input[type=number]::-webkit-inner-spin-button, 
input[type=number]::-webkit-outer-spin-button { 
  -webkit-appearance: none; 
}

After trying EVERY solution google came up with on stack overflow, I found what my particular problem was. I had edited my hosts file a long time ago to allow me to access my localhost from my virtualbox.

Removing this entry solved it for me, along with the correct installation of mongoDB from the link given in the above solution, and including the correct promise handling code:

mongoose.connect('mongodb://localhost/testdb').then(() => {
console.log("Connected to Database");
}).catch((err) => {
    console.log("Not Connected to Database ERROR! ", err);
});

Modules Preconditions:

The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (precondition="managedHandler") only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:

<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />

If you remove the attribute precondition="managedHandler", Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.

You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "managedHandler" precondition.

To enable all managed modules to run for all requests without configuring each module entry to remove the "managedHandler" precondition, use the runAllManagedModulesForAllRequests property in the <modules> section:

<modules runAllManagedModulesForAllRequests="true" />    

When you use this property, the "managedHandler" precondition has no effect and all managed modules run for all requests.

I think it can help you:

CREATE PROCEDURE DEPT_COUNT
(
    @DEPT_NAME VARCHAR(20), -- Input parameter
    @D_COUNT INT OUTPUT     -- Output parameter
    -- Remember parameters begin with "@"
)
AS -- You miss this word in your example
BEGIN
    SELECT COUNT(*) 
    INTO #D_COUNT -- Into a Temp Table (prefix "#")
    FROM INSTRUCTOR
    WHERE INSTRUCTOR.DEPT_NAME = DEPT_COUNT.DEPT_NAME
END

Then, you can call the SP like this way, for example:

DECLARE @COUNTER INT
EXEC DEPT_COUNT 'DeptName', @COUNTER OUTPUT
SELECT @COUNTER

If you have problem with adblock blocking new tab in browser you can do something like this:

$('a').click(function(e){ // change $('a') into more specific selector
    const openedWindow = window.open(this.href, '_blank');

    // Check if browser tab was closed within 0.3 second (user can't, adblock does).
    setTimeout(() => {
        if (openedWindow.closed) {
            alert('Adblock detected!');
        }
    }, 300);

    e.preventDefault(); // return false if you like
});

This code is ONLY useful IF you don't want to block entire site AND just tell users why their browser tabs are closed ;)

Copying to the clipboard is a tricky task to do in Javascript in terms of browser compatibility. The best way to do it is using a small flash. It will work on every browser. You can check it in this article.

Here's how to do it for Internet Explorer:

function copy (str)
{
    //for IE ONLY!
    window.clipboardData.setData('Text',str);
}

Since Python 3.0 you have to write:

print("Hello world!")

And someone still has to write that antigravity library :(

The main problem as stated by preceding coments is malformed HTML, so an html cleaner or HTML-XML converter is a must. Once you get the XML code (XHTML) there are plenty of tools to handle it. You could get it with a simple SAX handler that extracts only the data you need or any tree-based method (DOM, JDOM, etc.) that let you even modify original code.

Here is a sample code that uses HTML cleaner to get all DIVs that use a certain class and print out all Text content inside it.

import java.io.IOException;
import java.net.URL;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

import org.htmlcleaner.HtmlCleaner;
import org.htmlcleaner.TagNode;

    static final String url = "http://www.stackoverflow.com";

    TagNode rootNode;

    public TestHtmlParse(URL htmlPage) throws IOException
    {
        HtmlCleaner cleaner = new HtmlCleaner();
        rootNode = cleaner.clean(htmlPage);
    }

    List getDivsByClass(String CSSClassname)
    {
        List divList = new ArrayList();

        {
            String classType = divElements[i].getAttributeByName("class");
            if (classType != null && classType.equals(CSSClassname))
            {
                divList.add(divElements[i]);

                TagNode divElement = (TagNode) iterator.next();
                System.out.println("Text child nodes of DIV: " + divElement.getText().toString());

    }
}

You can create new User library,

On

"Configure Build Paths" page -> Add Library -> User Library (on list) -> User Libraries Button (rigth side of page)

and create your library and (add Jars buttons) include your specific Jars.

I hope this can help you.

Here's a simple example in C++11.

#include <mutex>    // mutex
#include <iostream> // cout 
#include <cstdio>   // getchar
#include <thread>   // this_thread, yield
#include <future>   // async
#include <chrono>   // seconds

using namespace std;
mutex _m1;
mutex _m2;

// Deadlock will occur because func12 and func21 acquires the two locks in reverse order

void func12()
{
    unique_lock<mutex> l1(_m1);
    this_thread::yield(); // hint to reschedule
    this_thread::sleep_for( chrono::seconds(1) );
    unique_lock<mutex> l2(_m2 );
}

void func21()
{
    unique_lock<mutex> l2(_m2);
    this_thread::yield(); // hint to reschedule
    this_thread::sleep_for( chrono::seconds(1) );
    unique_lock<mutex> l1(_m1);
}

int main( int argc, char* argv[] )
{
    async(func12);
    func21();
    cout << "All done!"; // this won't be executed because of deadlock
    getchar();
}

As @ashishduh mentioned above, using android:autoLink="phone is also a good solution. But this option comes with one drawback, it doesn't work with all phone number lengths. For instance, a phone number of 11 numbers won't work with this option. The solution is to prefix your phone numbers with the country code.

Example:

08034448845 won't work

but +2348034448845 will

There may be many ways.. But I implemented by following two ways

Given example is of maven project.

1. Using Dockerfile in maven project

Use the following file structure:

Demo
+-- src
|    +-- main
|    ¦   +-- java
|    ¦       +-- org
|    ¦           +-- demo
|    ¦               +-- Application.java
|    ¦   
|    +-- test
|
+---- Dockerfile
+---- pom.xml

And update the Dockerfile as:

FROM java:8
EXPOSE 8080
ADD /target/demo.jar demo.jar
ENTRYPOINT ["java","-jar","demo.jar"]

Navigate to the project folder and type following command you will be ab le to create image and run that image:

$ mvn clean
$ mvn install
$ docker build -f Dockerfile -t springdemo .
$ docker run -p 8080:8080 -t springdemo

Get video at Spring Boot with Docker

2. Using Maven plugins

Add given maven plugin in pom.xml

<plugin>
    <groupId>com.spotify</groupId>
    <artifactId>docker-maven-plugin</artifactId>
    <version>0.4.5</version>
        <configuration>
            <imageName>springdocker</imageName>
            <baseImage>java</baseImage>
            <entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint>
            <resources>
                <resource>
                    <targetPath>/</targetPath>
                    <directory>${project.build.directory}</directory>
                    <include>${project.build.finalName}.jar</include>
                </resource>
            </resources>
        </configuration>
    </plugin>

Navigate to the project folder and type following command you will be able to create image and run that image:

$ mvn clean package docker:build
$ docker images
$ docker run -p 8080:8080 -t <image name>

In first example we are creating Dockerfile and providing base image and adding jar an so, after doing that we will run docker command to build an image with specific name and then run that image..

Whereas in second example we are using maven plugin in which we providing baseImage and imageName so we don't need to create Dockerfile here.. after packaging maven project we will get the docker image and we just need to run that image..

You can use mb_strlen() to get the byte length using a encoding that only have byte-characters, without worring about multibyte or singlebyte strings. For example, as drake127 saids in a comment of mb_strlen, you can use '8bit' encoding:

<?php
    $string = 'Cién cañones por banda';
    echo mb_strlen($string, '8bit');
?>

You can have problems using strlen function since php have an option to overload strlen to actually call mb_strlen. See more info about it in http://php.net/manual/en/mbstring.overload.php

For trim the string by byte length without split in middle of a multibyte character you can use:

mb_strcut(string $str, int $start [, int $length [, string $encoding ]] )

This works for me consistently (it happens to me from time to time, when I do things such a restart tomcat when I am running the integration tests, for example)

1) Find the process that has the port 1099 open

sudo netstat -anp | grep tcp | grep 1099
cp6       0      0 :::1099                 :::*                    LISTEN      9857/java

2) kill it

kill 9857

3) Start Tomcat.

You can try using Descriptor, to limit the size

class fixedSizeArray(object):
    def __init__(self, arraySize=5):
        self.arraySize = arraySize
        self.array = [None] * self.arraySize

    def __repr__(self):
        return str(self.array)

    def __get__(self, instance, owner):
        return self.array

    def append(self, index=None, value=None):
        print "Append Operation cannot be performed on fixed size array"
        return

    def insert(self, index=None, value=None):
        if not index and index - 1 not in xrange(self.arraySize):
            print 'invalid Index or Array Size Exceeded'
            return
        try:
            self.array[index] = value
        except:
            print 'This is Fixed Size Array: Please Use the available Indices'


arr = fixedSizeArray(5)
print arr
arr.append(100)
print arr
arr.insert(1, 200)
print arr
arr.insert(5, 300)
print arr

OUTPUT:

[None, None, None, None, None]
Append Operation cannot be performed on fixed size array
[None, None, None, None, None]
[None, 200, None, None, None]
This is Fixed Size Array: Please Use the available Indices
[None, 200, None, None, None]

jQuery

$('input[type=checkbox]').removeAttr('checked');

Or

<!-- checked -->
<input type='checkbox' name='foo' value='bar' checked=''/> 

<!-- unchecked -->
<input type='checkbox' class='inputUncheck' name='foo' value='bar' checked=''/> 
<input type='checkbox' class='inputUncheck' name='foo' value='bar'/> 

+

$('input.inputUncheck').removeAttr('checked');

According to the previous answers, it seems that mathematically, we simply think in a higher order. Instead of thinking a value x having type X, we think of a function x: T ? X, where T is the type of time, be it the natural numbers, the integers or the continuum. Now when we write y := x + 1 in the programming language, we actually mean the equation y(t) = x(t) + 1.

The database must have a name (example DB1), try this one:

OracleConnection con = new OracleConnection("data source=DB1;user id=fastecit;password=fastecit"); 

In case the TNS is not defined you can also try this one:

OracleConnection con = new OracleConnection("Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=DB1)));
User Id=fastecit;Password=fastecit"); 

This worked for me: RatingBar should be inside LinearLayout other than having layout width set to wrap content for RatingBar.

I'm using Conda on Windows and this answer did not work for me. But I can suggest another solution:

• rename enviroment folder (old_name to new_name)

• open shell and activate env with custom folder:

  conda.bat activate "C:\Users\USER_NAME\Miniconda3\envs\new_name"

• now you can use this enviroment, but it's not on the enviroment list. Update\install\remove any package to fix it. For example, update numpy:

  conda update numpy

• after applying any action to package, the environment will show in env list. To check this, type:

  conda env list

You can do this:

cat("File not supplied.\nUsage: ./program F=filename\n")

Notice that cat has a return value of NULL.

Check this page out: http://matplotlib.org/examples/pylab_examples/subplots_demo.html

plt.subplots is similar. I think it's better since it's easier to set parameters of the figure. The first two arguments define the layout (in your case 1 row, 2 columns), and other parameters change features such as figure size:

import numpy as np
import matplotlib.pyplot as plt

x1 = np.linspace(0.0, 5.0)
x2 = np.linspace(0.0, 2.0)
y1 = np.cos(2 * np.pi * x1) * np.exp(-x1)
y2 = np.cos(2 * np.pi * x2)

fig, axes = plt.subplots(nrows=1, ncols=2, figsize=(5, 3))
axes[0].plot(x1, y1)
axes[1].plot(x2, y2)
fig.tight_layout()

Another option is using eval and parse, as in

d = 5
for (i in 1:10){
     eval(parse(text = paste('a', 1:10, ' = d + rnorm(3)', sep='')[i]))
}

You're forgetting to read it as binary too.

In your write part you have:

open(b"Fruits.obj","wb") # Note the wb part (Write Binary)

In the read part you have:

file = open("Fruits.obj",'r') # Note the r part, there should be a b too

So replace it with:

file = open("Fruits.obj",'rb')

And it will work :)

As for your second error, it is most likely cause by not closing/syncing the file properly.

Try this bit of code to write:

>>> import pickle
>>> filehandler = open(b"Fruits.obj","wb")
>>> pickle.dump(banana,filehandler)
>>> filehandler.close()

And this (unchanged) to read:

>>> import pickle
>>> file = open("Fruits.obj",'rb')
>>> object_file = pickle.load(file)

A neater version would be using the with statement.

For writing:

>>> import pickle
>>> with open('Fruits.obj', 'wb') as fp:
>>>     pickle.dump(banana, fp)

For reading:

>>> import pickle
>>> with open('Fruits.obj', 'rb') as fp:
>>>     banana = pickle.load(fp)

You can do it like this:

row_id = 5;
row = $("body").find('#'+row_id);

A Python 2+3 compatible solution is:

import sys

if sys.version_info[0] >= 3:
    from urllib.request import urlretrieve
else:
    # Not Python 3 - today, it is most likely to be Python 2
    # But note that this might need an update when Python 4
    # might be around one day
    from urllib import urlretrieve

# Get file from URL like this:
urlretrieve("http://www-scf.usc.edu/~chiso/oldspice/m-b1-hello.mp3")

Use Activity.getWindow() to get the window of your activity; use Window.addFlags() to add whichever of the following flags in WindowManager.LayoutParams that you desire:

• FLAG_DISMISS_KEYGUARD

• FLAG_SHOW_WHEN_LOCKED

• FLAG_TURN_SCREEN_ON

Take a peek at the man page for sort...

   -n, --numeric-sort
          compare according to string numerical value

So here is an example...

sort -n filename

Actually it's: request.getHeader("Referer"), or even better, and to be 100% sure, request.getHeader(HttpHeaders.REFERER), where HttpHeaders is com.google.common.net.HttpHeaders

You can do this by creating a constraint and connecting it via interface builder

See explanation: Auto_Layout_Constraints_in_Interface_Builder

raywenderlich beginning-auto-layout

AutolayoutPG Articles constraint Fundamentals

@interface ViewController : UIViewController {
    IBOutlet NSLayoutConstraint *leadingSpaceConstraint;
    IBOutlet NSLayoutConstraint *topSpaceConstraint;
}
@property (weak, nonatomic) IBOutlet NSLayoutConstraint *leadingSpaceConstraint;

connect this Constraint outlet with your sub views Constraint or connect super views Constraint too and set it according to your requirements like this

 self.leadingSpaceConstraint.constant = 10.0;//whatever you want to assign

I hope this clarifies it.

Usage depends on whether the component's parent has a layout manager or not.

• setSize() -- use when a parent layout manager does not exist;
• setPreferredSize() (also its related setMinimumSize and setMaximumSize) -- use when a parent layout manager exists.

The setSize() method probably won't do anything if the component's parent is using a layout manager; the places this will typically have an effect would be on top-level components (JFrames and JWindows) and things that are inside of scrolled panes. You also must call setSize() if you've got components inside a parent without a layout manager.

Generally, setPreferredSize() will lay out the components as expected if a layout manager is present; most layout managers work by getting the preferred (as well as minimum and maximum) sizes of their components, then using setSize() and setLocation() to position those components according to the layout's rules.

For example, a BorderLayout tries to make the bounds of its "north" region equal to the preferred size of its north component---they may end up larger or smaller than that, depending on the size of the JFrame, the size of the other components in the layout, and so on.

Answer is Objective C

if (player.timeControlStatus == AVPlayerTimeControlStatusPlaying) {
    //player is playing
}
else if (player.timeControlStatus == AVPlayerTimeControlStatusPaused) {
    //player is pause
}
else if (player.timeControlStatus == AVPlayerTimeControlStatusWaitingToPlayAtSpecifiedRate) {
    //player is waiting to play
}

You need to repartition the Dataframe in a single partition and then define the format, path and other parameter to the file in Unix file system format and here you go,

df.repartition(1).write.format('com.databricks.spark.csv').save("/path/to/file/myfile.csv",header = 'true')

Read more about the repartition function Read more about the save function

However, repartition is a costly function and toPandas() is worst. Try using .coalesce(1) instead of .repartition(1) in previous syntax for better performance.

Read more on repartition vs coalesce functions.

In android studio you can easily press:

1. Ctrl + Shift + Alt + S.
2. If you have a newer version of android studio, then press on app first. Then, continue with step three as follows.
3. A window will open with a bunch of options
4. Go to Flavors and that's actually all you need

You can also change the versionCode of your app there.

As far as I understand, you have more than one form tag in your web page that causes the problem. Make sure you have only one server-side form tag for each page.

If you are pushing a new private image for the first time, make sure your subscription supports this extra image.

Docker allows you to have 6 private images named, even if you only pay for 5, but not to push that 6th image. The lack of an informative message is confusing and irritating.

Try this (faster and simpler):

newData <- data^2

I just wanted to add, that if you use CloudFlare (free), you can use their API to manage your dns with ease.

This is excellent practice.

By creating variables inside loops, you ensure their scope is restricted to inside the loop. It cannot be referenced nor called outside of the loop.

This way:

• If the name of the variable is a bit "generic" (like "i"), there is no risk to mix it with another variable of same name somewhere later in your code (can also be mitigated using the -Wshadow warning instruction on GCC)

• The compiler knows that the variable scope is limited to inside the loop, and therefore will issue a proper error message if the variable is by mistake referenced elsewhere.

• Last but not least, some dedicated optimization can be performed more efficiently by the compiler (most importantly register allocation), since it knows that the variable cannot be used outside of the loop. For example, no need to store the result for later re-use.

In short, you are right to do it.

Note however that the variable is not supposed to retain its value between each loop. In such case, you may need to initialize it every time. You can also create a larger block, encompassing the loop, whose sole purpose is to declare variables which must retain their value from one loop to another. This typically includes the loop counter itself.

{
    int i, retainValue;
    for (i=0; i<N; i++)
    {
       int tmpValue;
       /* tmpValue is uninitialized */
       /* retainValue still has its previous value from previous loop */

       /* Do some stuff here */
    }
    /* Here, retainValue is still valid; tmpValue no longer */
}

For question #2: The variable is allocated once, when the function is called. In fact, from an allocation perspective, it is (nearly) the same as declaring the variable at the beginning of the function. The only difference is the scope: the variable cannot be used outside of the loop. It may even be possible that the variable is not allocated, just re-using some free slot (from other variable whose scope has ended).

With restricted and more precise scope come more accurate optimizations. But more importantly, it makes your code safer, with less states (i.e. variables) to worry about when reading other parts of the code.

This is true even outside of an if(){...} block. Typically, instead of :

    int result;
    (...)
    result = f1();
    if (result) then { (...) }
    (...)
    result = f2();
    if (result) then { (...) }

it's safer to write :

    (...)
    {
        int const result = f1();
        if (result) then { (...) }
    }
    (...)
    {
        int const result = f2();
        if (result) then { (...) }
    }

The difference may seem minor, especially on such a small example. But on a larger code base, it will help : now there is no risk to transport some result value from f1() to f2() block. Each result is strictly limited to its own scope, making its role more accurate. From a reviewer perspective, it's much nicer, since he has less long range state variables to worry about and track.

Even the compiler will help better : assuming that, in the future, after some erroneous change of code, result is not properly initialized with f2(). The second version will simply refuse to work, stating a clear error message at compile time (way better than run time). The first version will not spot anything, the result of f1() will simply be tested a second time, being confused for the result of f2().

Complementary information

The open-source tool CppCheck (a static analysis tool for C/C++ code) provides some excellent hints regarding optimal scope of variables.

In response to comment on allocation: The above rule is true in C, but might not be for some C++ classes.

For standard types and structures, the size of variable is known at compilation time. There is no such thing as "construction" in C, so the space for the variable will simply be allocated into the stack (without any initialization), when the function is called. That's why there is a "zero" cost when declaring the variable inside a loop.

However, for C++ classes, there is this constructor thing which I know much less about. I guess allocation is probably not going to be the issue, since the compiler shall be clever enough to reuse the same space, but the initialization is likely to take place at each loop iteration.

For me the sdk version mentioned in build.gradle wasn't installed. Used SDK Manager to install the right SDK version and it worked

Check below code for converting json to array in PHP, If JSON is correct then json_decode() works well, and will return an array, But if malformed JSON, then It will return NULL,

<?php
function jsonDecode1($json){
    $arr = json_decode($json, true);
    return $arr;
}

// In case of malformed JSON, it will return NULL
var_dump( jsonDecode1($json) );

If malformed JSON, and you are expecting only array, then you can use this function,

<?php
function jsonDecode2($json){
    $arr = (array) json_decode($json, true);
    return $arr;
}

// In case of malformed JSON, it will return an empty array()
var_dump( jsonDecode2($json) );

If malformed JSON, and you want to stop code execution, then you can use this function,

<?php
function jsonDecode3($json){
    $arr = (array) json_decode($json, true);

    if(empty(json_last_error())){
        return $arr;
    }
    else{
        throw new ErrorException( json_last_error_msg() );
    }
}

// In case of malformed JSON, Fatal error will be generated
var_dump( jsonDecode3($json) );

You can use any function depends on your requirement,

You can also try this if you want to occur for all the queries:

I also struggled finding articles on how to just generate the token part. I never found one and wrote my own. So if it helps:

The things to do are:

• Create a new web application
• Install the following NuGet packages:
  • Microsoft.Owin
  • Microsoft.Owin.Host.SystemWeb
  • Microsoft.Owin.Security.OAuth
  • Microsoft.AspNet.Identity.Owin
• Add a OWIN startup class

Then create a HTML and a JavaScript (index.js) file with these contents:

var loginData = 'grant_type=password&[email protected]&password=test123';

var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function () {
    if (xmlhttp.readyState === 4 && xmlhttp.status === 200) {
        alert(xmlhttp.responseText);
    }
}
xmlhttp.open("POST", "/token", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send(loginData);

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>
    <script type="text/javascript" src="index.js"></script>
</body>
</html>

The OWIN startup class should have this content:

using System;
using System.Security.Claims;
using Microsoft.Owin;
using Microsoft.Owin.Security.OAuth;
using OAuth20;
using Owin;

[assembly: OwinStartup(typeof(Startup))]

namespace OAuth20
{
    public class Startup
    {
        public static OAuthAuthorizationServerOptions OAuthOptions { get; private set; }

        public void Configuration(IAppBuilder app)
        {
            OAuthOptions = new OAuthAuthorizationServerOptions()
            {
                TokenEndpointPath = new PathString("/token"),
                Provider = new OAuthAuthorizationServerProvider()
                {
                    OnValidateClientAuthentication = async (context) =>
                    {
                        context.Validated();
                    },
                    OnGrantResourceOwnerCredentials = async (context) =>
                    {
                        if (context.UserName == "[email protected]" && context.Password == "test123")
                        {
                            ClaimsIdentity oAuthIdentity = new ClaimsIdentity(context.Options.AuthenticationType);
                            context.Validated(oAuthIdentity);
                        }
                    }
                },
                AllowInsecureHttp = true,
                AccessTokenExpireTimeSpan = TimeSpan.FromDays(1)
            };

            app.UseOAuthBearerTokens(OAuthOptions);
        }
    }
}

Run your project. The token should be displayed in the pop-up.

Give you a pagination component, which is maybe a little difficult to understand for newbie to react:

https://www.npmjs.com/package/pagination

[u'{email:[email protected],gem:0}', u'{email:test,gem:0}', u'{email:test,gem:0}', u'{email:test,gem:0}', u'{email:test,gem:0}', u'{email:test1,gem:0}']

'u' denotes unicode characters. We can easily remove this with map function on the final list element

map(str, test)

Another way is when you are appending it to the list

test.append(str(a))

     foreach (DataRow row in DataRow row in GridView1.Rows)
        {
            foreach (DataColumn c in GridView1.Columns)

               bool ckbVal = (bool)(row[c.ColumnName]);

        }

You're looking for things like the haversine formula. See here as well.

There's other ones but this is the most commonly cited.

If you're looking for something even more robust, you might want to look at your databases GIS capabilities. They're capable of some cool things like telling you whether a point (City) appears within a given polygon (Region, Country, Continent).

If you just have a plain url string (and therefore don't have a hash attribute) you can also use a regular expression:

var url = "www.example.com/task1/1.3.html#a_1"  
var anchor = url.match(/#(.*)/)[1] 

It accepts only a string value of "true" to represent boolean true. Best what you can do is

boolean uses_votes = "1".equals(o.get("uses_votes"));

Or if the Map actually represents an "entitiy", I think a Javabean is way much better. Or if it represents configuration settings, you may want to take a look into Apache Commons Configuration.

if you add your remote repository by using git clone then follow the steps:-

git clone <repo_url> then

git init

git add * *means add all files

git commit -m 'your commit'

git remote -v for check any branch run or not if not then nothing show then we add or fetch the repository. "fetch first". You need to run git pull origin <branch> or git pull -r origin <branch> before a next push.

then

git remote add origin <git url>
 git pull -r origin master
git push -u origin master```

There was auto generated Copyright message in XML and a blank line before <resources> tag, once I removed it my build was successful.

For C99 there is P99_DECLARE_ENUM in P99 that lets you simply declare enum like this:

P99_DECLARE_ENUM(color, red, green, blue);

and then use color_getname(A) to obtain a string with the color name.

Yes it makes sense to use requireJS with Angular, I spent several days to test several technical solutions.

I made an Angular Seed with RequireJS on Server Side. Very simple one. I use SHIM notation for no AMD module and not AMD because I think it's very difficult to deal with two different Dependency injection system.

I use grunt and r.js to concatenate js files on server depends on the SHIM configuration (dependency) file. So I refer only one js file in my app.

For more information go on my github Angular Seed : https://github.com/matohawk/angular-seed-requirejs

"...by a class and a div."

I assume when you say "div" you mean "id"? Try this:

$('#test2.test1').prop('checked', true);

No need to muck about with your [attributename=value] style selectors because id has its own format as does class, and they're easily combined although given that id is supposed to be unique it should be enough on its own unless your meaning is "select that element only if it currently has the specified class".

Or more generally to select an input where you want to specify a multiple attribute selector:

$('input:radio[class=test1][id=test2]').prop('checked', true);

That is, list each attribute with its own square brackets.

Note that unless you have a pretty old version of jQuery you should use .prop() rather than .attr() for this purpose.

Sorry for late reply but still felt like posting my answer if it helps.It works for 6 digits OTP.

    @Override
    public void onOTPReceived(String messageBody)

        {
            otp = matcher.group();
        }
        checkAndSetOTP(otp);
    }
Adding constants here

public static final String OTP_REGEX = "[0-9]{1,6}";

For SMS listener one can follow the below class

        return currentSMS;
    }

Just in case you are able to utilize a scripting language to prepare your SQL queries, you could reuse field=value pairs by using SET instead of (a,b,c) VALUES(a,b,c).

An example with PHP:

$pairs = "a=$a,b=$b,c=$c";
$query = "INSERT INTO $table SET $pairs ON DUPLICATE KEY UPDATE $pairs";

Example table:

CREATE TABLE IF NOT EXISTS `tester` (
  `a` int(11) NOT NULL,
  `b` varchar(50) NOT NULL,
  `c` text NOT NULL,
  UNIQUE KEY `a` (`a`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

if you want to run app in debug mode

1) Look at Left Side bottom, above Favorites there is Build Variants

2) Click on Build Variants. Click on release and choose debug

it works perfect !!!

I think what you want to do is

<link rel="stylesheet" type="text/css" href="font/font-face/my-font-face.css">

Yes.
Code must be compiled with Java 8 compliant compiler with option to store formal parameter names turned on (-parameters option).
Then this code snippet should work:

Class<String> clz = String.class;
for (Method m : clz.getDeclaredMethods()) {
   System.err.println(m.getName());
   for (Parameter p : m.getParameters()) {
    System.err.println("  " + p.getName());
   }
}

You can also get through it by the code below:

file=open(completefilepath,'r',encoding='utf8',errors="ignore")
file.read()

Create a new constraint first and then drop the old one.
That way you ensure that:

• constraints are always in place
• existing rows do not violate new constraints
• no illegal INSERT/UPDATEs are attempted after you drop a constraint and before a new one is applied.

This works fine for me:

while True:
   answer = input('Do you want to continue?:')
   if answer.lower().startswith("y"):
      print("ok, carry on then")
   elif answer.lower().startswith("n"):
      print("sayonara, Robocop")
      exit()

edit: use input in python 3.2 instead of raw_input

Cast the operands to floats:

float ans = (float)a / (float)b;

For me below worked:

Step 1: Downloaded and installed the web Installer exe from https://www.microsoft.com/en-us/download/details.aspx?id=48137 on the application server. Rebooted the application server after installation was completed.

Step 2: Added below changes in the web.config

<system.web>
    <compilation targetFramework="4.6"/> <!-- Changed framework 4.0 to 4.6 -->
    <!--Added this httpRuntime -->
    <httpRuntime targetFramework="4.6" />
</system.web>

Step 3: After completing step 1 and 2, it gave an error, "WebForms UnobtrusiveValidationMode requires a ScriptResourceMapping for 'jquery'. Please add a ScriptResourceMapping named jquery(case-sensitive)" and to resolve this error, I added below key in appsettings in my web.config file

<appSettings>
      <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
</appSettings>

^ marks the beginning of the line and $ marks the end of the line. This will return exact matches of "OK" only:

(This also works with double quotes if that's your preference.)

grep '^OK$'

If there are other characters before the OK / NOTOK (like the job name), you can exclude the "NOT" prefix by allowing any characters .* and then excluding "NOT" [^NOT] just before the "OK":

grep '^.*[^NOT]OK$'

1. Login as default user: sudo -i -u postgres
2. Create new User: createuser --interactive
3. When prompted for role name, enter linux username, and select Yes to superuser question.
4. Still logged in as postgres user, create a database: createdb <username_from_step_3>
5. Confirm error(s) are gone by entering: psql at the command prompt.
6. Output should show psql (x.x.x) Type "help" for help.

This might help. It contains many examples which will be useful in understanding.

    });

Just use the result from the FOR command. For example (inside a batch file):

for /F "delims=" %%I in ('dir /b /a-d /od FILESA*') do (echo %%I)

You can use the %%I as the value you want. Just like this: %%I.

And in advance the %%I does not have any spaces or CR characters and can be used for comparisons!!

I was unable to find the direct download detailed in davidnr's post. You can download the ISO directly from the Microsoft Download Center here: https://download.microsoft.com/download/b/e/d/bedddfc4-55f4-4748-90a8-ffe38a40e89f/vs2015.3.com_enu.iso.

In regards to your error and what's missing in your code. m is a name which is not defined for getmd5() function.

No offence, I know you are a beginner, but your code is all over the place. Let's look at your issues one by one :)

First, you are not using hashlib.md5.hexdigest() method correctly. Please refer explanation on hashlib functions in Python Doc Library. The correct way to return MD5 for provided string is to do something like this:

>>> import hashlib
>>> hashlib.md5("filename.exe").hexdigest()
'2a53375ff139d9837e93a38a279d63e5'

However, you have a bigger problem here. You are calculating MD5 on a file name string, where in reality MD5 is calculated based on file contents. You will need to basically read file contents and pipe it though MD5. My next example is not very efficient, but something like this:

>>> import hashlib
>>> hashlib.md5(open('filename.exe','rb').read()).hexdigest()
'd41d8cd98f00b204e9800998ecf8427e'

As you can clearly see second MD5 hash is totally different from the first one. The reason for that is that we are pushing contents of the file through, not just file name.

A simple solution could be something like that:

# Import hashlib library (md5 method is part of it)
import hashlib

# File to check
file_name = 'filename.exe'

# Correct original md5 goes here
original_md5 = '5d41402abc4b2a76b9719d911017c592'  

# Open,close, read file and calculate MD5 on its contents 
with open(file_name) as file_to_check:
    # read contents of the file
    data = file_to_check.read()    
    # pipe contents of the file through
    md5_returned = hashlib.md5(data).hexdigest()

# Finally compare original MD5 with freshly calculated
if original_md5 == md5_returned:
    print "MD5 verified."
else:
    print "MD5 verification failed!."

Please look at the post Python: Generating a MD5 checksum of a file. It explains in detail a couple of ways how it can be achieved efficiently.

Best of luck.

Your best bet over here to install XAMPP..Follow the link download it , it has an instruction file as well. You can setup your own MY SQL database and then connect to on your local machine.

From git doc: http://git-scm.com/docs/git-stash

drop [-q|--quiet] []

Remove a single stashed state from the stash list. When no is given, it removes the latest one. i.e. stash@{0}, otherwise must be a valid stash log reference of the form stash@{}.

example:

git stash drop stash@{5}

This would delete the stash entry 5. To see all the list of stashes:

git stash list

The quick answer is: Windows Presentation Foundation (WPF) is basically a way of displaying user interface. (see this)

Windows Communication Foundation (WCF) is a framework for creating service oriented applications. (see this)

As for which one you should use, it depends on your requirement. Usually an application written in WPF, ASP.NET..etc called the WCF service to do some processing at the server-side and the service returns the result to the application that called it.

For me it was a problem with firebase package.

Only add "@firebase/database": "0.2.1", for your package.json, reinstall node_modules and works.

**write this before adding view to dialog.**

dialog1.requestWindowFeature(Window.FEATURE_NO_TITLE);

The reason for the error is that the nextInt only pulls the integer, not the newline. If you add a in.nextLine() before your for loop, it will eat the empty new line and allow you to enter 3 names.

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = in.nextInt();

names = new String[nnames];
in.nextLine();
for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

or just read the line and parse the value as an Integer.

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = Integer.parseInt(in.nextLine().trim());

names = new String[nnames];
for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

My solution is casting each value with the help of callback function:

$ids = array_map( function($value) { return (int)$value; }, $ids )

It's easier to kill a session, when some meaningful name is given:

//Creation:
screen -S some_name proc
// Kill detached session
screen -S some_name -X quit

Yes, the way you are doing it is perfectly legitimate. To access that data on the client side, edit your success function to accept a parameter: data.

$.ajax({
    type: "POST",
    url: "somescript.php",
    datatype: "html",
    data: dataString,
    success: function(data) {
        doSomething(data);
    }
});

This works for any object, not just functions:

IF OBJECT_ID('YourObjectName') IS NOT NULL 

then just add your flavor of object, as in:

IF OBJECT_ID('YourFunction') IS NOT NULL
   DROP FUNCTION YourFunction

Maybe this method would help you for precising double values.

double truncate(double number)
    {
        int integerPart = (int) number;
        double fractionalPart = number - integerPart;
        fractionalPart *= 100;  //It is for upto two decimal values after point.
                                //You can increase the zeros to fulfill your needs.
        int fractPart = (int) fractionalPart;
        fractionalPart = (double) (integerPart) + (double) (fractPart)/100;
        return fractionalPart;
    }

This method will allow to set the precision level.

double truncate(double number, int precision)
{
    double prec = Math.pow(10, precision);
    int integerPart = (int) number;
    double fractionalPart = number - integerPart;
    fractionalPart *= prec;
    int fractPart = (int) fractionalPart;
    fractionalPart = (double) (integerPart) + (double) (fractPart)/prec;
    return fractionalPart;
}

Quick tweak to @alex-rodrigues answer... deals with shape including the number of channels.

import cv2
import numpy as np

def rotateImage(image, angle):
    center=tuple(np.array(image.shape[0:2])/2)
    rot_mat = cv2.getRotationMatrix2D(center,angle,1.0)
    return cv2.warpAffine(image, rot_mat, image.shape[0:2],flags=cv2.INTER_LINEAR)

Just try this in razor

@{
    var selectList = new SelectList(
        new List<SelectListItem>
        {
            new SelectListItem {Text = "Google", Value = "Google"},
            new SelectListItem {Text = "Other", Value = "Other"},
        }, "Value", "Text");
}

and then

@Html.DropDownListFor(m => m.YourFieldName, selectList, "Default label", new { @class = "css-class" })

or

@Html.DropDownList("ddlDropDownList", selectList, "Default label", new { @class = "css-class" })

PROJECT eliminates columns while SELECT eliminates rows.

Make sure that in case your image is not in the dom, and you get it from local directory or server, you should wait for the image to load and just after that to draw it on the canvas.

something like that:

function drawBgImg() {
    let bgImg = new Image();
    bgImg.src = '/images/1.jpg';
    bgImg.onload = () => {
        gCtx.drawImage(bgImg, 0, 0, gElCanvas.width, gElCanvas.height);
    }
}

I've recently released xUnit++, specifically as an alternative to Google Test and the Boost Test Library (view the comparisons). If you're familiar with xUnit.Net, you're ready for xUnit++.

#include "xUnit++/xUnit++.h"

FACT("Foo and Blah should always return the same value")
{
    Check.Equal("0", Foo()) << "Calling Foo() with no parameters should always return \"0\".";
    Assert.Equal(Foo(), Blah());
}

THEORY("Foo should return the same value it was given, converted to string", (int input, std::string expected),
    std::make_tuple(0, "0"),
    std::make_tuple(1, "1"),
    std::make_tuple(2, "2"))
{
    Assert.Equal(expected, Foo(input));
}

Main features:

• Incredibly fast: tests run concurrently.
• Portable
• Automatic test registration
• Many assertion types (Boost has nothing on xUnit++)
• Compares collections natively.
• Assertions come in three levels:
  • fatal errors
  • non-fatal errors
  • warnings
• Easy assert logging: Assert.Equal(-1, foo(i)) << "Failed with i = " << i;
• Test logging: Log.Debug << "Starting test"; Log.Warn << "Here's a warning";
• Fixtures
• Data-driven tests (Theories)
• Select which tests to run based on:
  • Attribute matching
  • Name substring matchin
  • Test Suites

The following will parse an XML string into an XML document in all major browsers. Unless you need support for IE <= 8 or some obscure browser, you could use the following function:

function parseXml(xmlStr) {
   return new window.DOMParser().parseFromString(xmlStr, "text/xml");
}

If you need to support IE <= 8, the following will do the job:

var parseXml;

if (typeof window.DOMParser != "undefined") {
    parseXml = function(xmlStr) {
        return new window.DOMParser().parseFromString(xmlStr, "text/xml");
    };
} else if (typeof window.ActiveXObject != "undefined" &&
       new window.ActiveXObject("Microsoft.XMLDOM")) {
    parseXml = function(xmlStr) {
        var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");
        xmlDoc.async = "false";
        xmlDoc.loadXML(xmlStr);
        return xmlDoc;
    };
} else {
    throw new Error("No XML parser found");
}

Once you have a Document obtained via parseXml, you can use the usual DOM traversal methods/properties such as childNodes and getElementsByTagName() to get the nodes you want.

Example usage:

var xml = parseXml("<foo>Stuff</foo>");
alert(xml.documentElement.nodeName);

If you're using jQuery, from version 1.5 you can use its built-in parseXML() method, which is functionally identical to the function above.

var xml = $.parseXML("<foo>Stuff</foo>");
alert(xml.documentElement.nodeName);

Try the following

if (c is TForm) { 
 ...
}

1. What is the difference between Git and GitHub?

   Git is a version control system; think of it as a series of snapshots (commits) of your code. You see a path of these snapshots, in which order they where created. You can make branches to experiment and come back to snapshots you took.

   GitHub, is a web-page on which you can publish your Git repositories and collaborate with other people.

2. Is Git saving every repository locally (in the user's machine) and in GitHub?

   No, it's only local. You can decide to push (publish) some branches on GitHub.

3. Can you use Git without GitHub? If yes, what would be the benefit for using GitHub?

   Yes, Git runs local if you don't use GitHub. An alternative to using GitHub could be running Git on files hosted on Dropbox, but GitHub is a more streamlined service as it was made especially for Git.

4. How does Git compare to a backup system such as Time Machine?

   It's a different thing, Git lets you track changes and your development process. If you use Git with GitHub, it becomes effectively a backup. However usually you would not push all the time to GitHub, at which point you do not have a full backup if things go wrong. I use git in a folder that is synchronized with Dropbox.

5. Is this a manual process, in other words if you don't commit you won't have a new version of the changes made?

   Yes, committing and pushing are both manual.

6. If are not collaborating and you are already using a backup system why would you use Git?

   • If you encounter an error between commits you can use the command git diff to see the differences between the current code and the last working commit, helping you to locate your error.

   • You can also just go back to the last working commit.

   • If you want to try a change, but are not sure that it will work. You create a branch to test you code change. If it works fine, you merge it to the main branch. If it does not you just throw the branch away and go back to the main branch.

   • You did some debugging. Before you commit you always look at the changes from the last commit. You see your debug print statement that you forgot to delete.

Make sure you check gitimmersion.com.

You can also add --disable-session-crashed-bubble to eliminate the errors that come up after a crash or improper shutdown.

//x=address or src
if(x.includes('/')==true){xp=x.split('/')} //split address
if(x.includes('\\')==true){xp=x.split('\\')} //split address
xl=xp.length*1-1;xn=xp[xl] //file==xn
xo=xn.split('.'); //file parts=xo
if(xo.lenght>2){xol=xo.length-1;xt=xo[xol];xr=xo.splice(xol,1);
xr=xr.join('.'); // multiple . in name
}else{
xr=xo[0]; //filename=xr
xt=xo[1]; //file ext=xt
}
xp.splice(xl,1); //remove file
xf=xp.join('/'); //folder=xf , also corrects slashes

//result
alert("filepath: "+x+"\n folder: "+xf+"("+xl+")\n file: "+xn+"\n filename: "+xr+"\n .ext:  "+xt)

I realize this is an old thread, but for those taking @JasonMArcher's accepted answer above as fact, I'm surprised it has not been corrected many of us have known for years it is actually the PIPELINE adding the delay and NOTHING to do with whether it is Out-Null or not. In fact, if you run the tests below you will quickly see that the same "faster" casting to [void] and $void= that for years we all used thinking it was faster, are actually JUST AS SLOW and in fact VERY SLOW when you add ANY pipelining whatsoever. In other words, as soon as you pipe to anything, the whole rule of not using out-null goes into the trash.

Proof, the last 3 tests in the list below. The horrible Out-null was 32339.3792 milliseconds, but wait - how much faster was casting to [void]? 34121.9251 ms?!? WTF? These are REAL #s on my system, casting to VOID was actually SLOWER. How about =$null? 34217.685ms.....still friggin SLOWER! So, as the last three simple tests show, the Out-Null is actually FASTER in many cases when the pipeline is already in use.

So, why is this? Simple. It is and always was 100% a hallucination that piping to Out-Null was slower. It is however that PIPING TO ANYTHING is slower, and didn't we kind of already know that through basic logic? We just may not have know HOW MUCH slower, but these tests sure tell a story about the cost of using the pipeline if you can avoid it. And, we were not really 100% wrong because there is a very SMALL number of true scenarios where out-null is evil. When? When adding Out-Null is adding the ONLY pipeline activity. In other words....the reason a simple command like $(1..1000) | Out-Null as shown above showed true.

If you simply add an additional pipe to Out-String to every test above, the #s change radically (or just paste the ones below) and as you can see for yourself, the Out-Null actually becomes FASTER in many cases:

git revert <hash>

Will revert a given commit. It sounds like you think git revert only affects the most recent commit.

That doesn't solve your problem, if you want to revert a change in a specific file and that commit changed more than that file.

Simply

MsgBox(GridView1.CurrentCell.Value.ToString)

document.getElementById("theForm").submit();

It works perfect in my case.

you can use it in function also like,

function submitForm()
{
     document.getElementById("theForm").submit();
} 

Set "theForm" as your form ID. It's done.

For Web Applications ( ASP.NET MVC and WebForm )

/// <summary>
/// Get current user ip address.
/// </summary>
/// <returns>The IP Address</returns>
public static string GetUserIPAddress()
{
    var context = System.Web.HttpContext.Current;
    string ip = String.Empty;

    if (context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != null)
        ip = context.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
    else if (!String.IsNullOrWhiteSpace(context.Request.UserHostAddress))
        ip = context.Request.UserHostAddress;

    if (ip == "::1")
        ip = "127.0.0.1";

    return ip;
}

For Windows Applications ( Windows Form, Console, Windows Service , ... )

    static void Main(string[] args)
    {
        HTTPGet req = new HTTPGet();
        req.Request("http://checkip.dyndns.org");
        string[] a = req.ResponseBody.Split(':');
        string a2 = a[1].Substring(1);
        string[] a3=a2.Split('<');
        string a4 = a3[0];
        Console.WriteLine(a4);
        Console.ReadLine();
    }

Adding my solution to the mix because it was a bit different and took me a while to figure out.

In my case I added a new class to one project but because my version control bindings weren't set I needed to make the file writable outside of Visual Studio (via the VC). I had cancelled out of the save in Visual Studio but after I made the file writable outside VS I then hit Save All again in VS. This inadvertently caused the new class file to not be saved in the project..however..Intellisense still showed it up as blue and valid in the referencing projects even though when I'd try to recompile the file wasn't found and got the type not found error. Closing and opening Visual Studio still showed the issue (but if I had taken note the class file was missing upon reopening).

Once I realized this, the fix was simple: with the project file set to writeable, readd the missing file to the project. All builds fine now.

It is rule of thumb that the first layer in your network should be the same shape as your data. For example our data is 28x28 images, and 28 layers of 28 neurons would be infeasible, so it makes more sense to 'flatten' that 28,28 into a 784x1. Instead of wriitng all the code to handle that ourselves, we add the Flatten() layer at the begining, and when the arrays are loaded into the model later, they'll automatically be flattened for us.

Here is an option with a table variable:

DECLARE @MyVar TABLE(Val DATETIME)
DECLARE @I INT, @StartDate DATETIME
SET @I = 1
SET @StartDate = '20100101'

WHILE @I <= 5
BEGIN
    INSERT INTO @MyVar(Val)
    VALUES(@StartDate)

    SET @StartDate = DATEADD(DAY,1,@StartDate)
    SET @I = @I + 1
END
SELECT *
FROM @MyVar

You can do the same with a temp table:

CREATE TABLE #MyVar(Val DATETIME)
DECLARE @I INT, @StartDate DATETIME
SET @I = 1
SET @StartDate = '20100101'

WHILE @I <= 5
BEGIN
    INSERT INTO #MyVar(Val)
    VALUES(@StartDate)

You should tell us what is your main goal, as was said by @JohnFx, this could probably be done another (more efficient) way.

If your (logical) check is for a negation (!) and you want to capture both JS null and undefined (as different Browsers will give you different results) you would use the less restrictive comparison: e.g.:

var ItemID = Item.get_id();
if (ItemID != null)
{
 //do stuff
}

This will capture both null and undefined

you can also pass the parameters through the command line. Command line arguments are stores in the array ARGV. so ARGV[0] is the first number and ARGV[1] the second number

#!/usr/bin/ruby

first_number = ARGV[0].to_i
second_number = ARGV[1].to_i

puts first_number + second_number

and you call it like this

% ./plus.rb 5 6
==> 11

Suppose a 9800GT GPU:

• it has 14 multiprocessors (SM)
• each SM has 8 thread-processors (AKA stream-processors, SP or cores)
• allows up to 512 threads per block
• warpsize is 32 (which means each of the 14x8=112 thread-processors can schedule up to 32 threads)

https://www.tutorialspoint.com/cuda/cuda_threads.htm

A block cannot have more active threads than 512 therefore __syncthreads can only synchronize limited number of threads. i.e. If you execute the following with 600 threads:

func1();
__syncthreads();
func2();
__syncthreads();

then the kernel must run twice and the order of execution will be:

1. func1 is executed for the first 512 threads
2. func2 is executed for the first 512 threads
3. func1 is executed for the remaining threads
4. func2 is executed for the remaining threads

Note:

The main point is __syncthreads is a block-wide operation and it does not synchronize all threads.

I'm not sure about the exact number of threads that __syncthreads can synchronize, since you can create a block with more than 512 threads and let the warp handle the scheduling. To my understanding it's more accurate to say: func1 is executed at least for the first 512 threads.

Before I edited this answer (back in 2010) I measured 14x8x32 threads were synchronized using __syncthreads.

I would greatly appreciate if someone test this again for a more accurate piece of information.

this is how:

   /**

    {
        $user_agent='Mozilla/5.0 (Windows NT 6.1; rv:8.0) Gecko/20100101 Firefox/8.0';

        $options = array(

        $header['errmsg']  = $errmsg;
        $header['content'] = $content;
        return $header;
    }

Example

//Read a web page and check for errors:

$result = get_web_page( $url );

if ( $result['errno'] != 0 )
    ... error: bad url, timeout, redirect loop ...

if ( $result['http_code'] != 200 )
    ... error: no page, no permissions, no service ...

$page = $result['content'];

This works the fastest for me

They're just trawling lists of web sites, and recording the resulting IP addresses in a database.

All you're seeing is the reverse mapping of that list. It's not guaranteed to be a full list (indeed more often than not it won't be) because it's impossible to learn every possible web site address.

Someone recommended Joda Time so - I have been using this CalendarDate class http://calendardate.sourceforge.net

It's a somewhat competing project to Joda Time, but much more basic at only 2 classes. It's very handy and worked great for what I needed since I didn't want to use a package bigger than my project. Unlike the Java counterparts, its smallest unit is the day so it is really a date (not having it down to milliseconds or something). Once you create the date, all you do to subtract is something like myDay.addDays(-5) to go back 5 days. You can use it to find the day of the week and things like that. Another example:

CalendarDate someDay = new CalendarDate(2011, 10, 27);
CalendarDate someLaterDay = today.addDays(77);

And:

//print 4 previous days of the week and today
String dayLabel = "";
CalendarDate today = new CalendarDate(TimeZone.getDefault());
CalendarDateFormat cdf = new CalendarDateFormat("EEE");//day of the week like "Mon"
CalendarDate currDay = today.addDays(-4);
while(!currDay.isAfter(today)) {
    dayLabel = cdf.format(currDay);
    if (currDay.equals(today))
        dayLabel = "Today";//print "Today" instead of the weekday name
    System.out.println(dayLabel);
    currDay = currDay.addDays(1);//go to next day
}

I think the function you're looking for is MONTH(date). You'll probably want to use 'YEAR' too.

Let's assume you have a table named things that looks something like this:

id happend_at
-- ----------------
1  2009-01-01 12:08
2  2009-02-01 12:00
3  2009-01-12 09:40
4  2009-01-29 17:55

And let's say you want to execute to find all the records that have a happened_at during the month 2009/01 (January 2009). The SQL query would be:

SELECT id FROM things 
   WHERE MONTH(happened_at) = 1 AND YEAR(happened_at) = 2009

Which would return:

id
---
1
3
4

Here:

window.onload = function start() {
    slide();
}
function slide() {
    var num = 0;
    for (num=0;num==10;) {
        setTimeout("document.getElementById('container').style.marginLeft='-600px'",3000);
        setTimeout("document.getElementById('container').style.marginLeft='-1200px'",6000);
        setTimeout("document.getElementById('container').style.marginLeft='-1800px'",9000);
        setTimeout("document.getElementById('container').style.marginLeft='0px'",12000);
    }
}

That makes it keep looping alright! That's why it isn't runnable here.

Initialize again select2 by new id or class like below

when the page load

$(".mynames").select2();

call again when came by ajax after success ajax function

$(".names").select2();

I'm going to start by disagreeing with part of the accepted (and well-upvoted) answer to this question by stating:

There are actually plenty of reasons why JITted code will run slower than a properly optimized C++ (or other language without runtime overhead) program including:

• compute cycles spent on JITting code at runtime are by definition unavailable for use in program execution.

• any hot paths in the JITter will be competing with your code for instruction and data cache in the CPU. We know that cache dominates when it comes to performance and native languages like C++ do not have this type of contention, by definition.

• a run-time optimizer's time budget is necessarily much more constrained than that of a compile-time optimizer's (as another commenter pointed out)

Bottom line: Ultimately, you will almost certainly be able to create a faster implementation in C++ than you could in C#.

Now, with that said, how much faster really isn't quantifiable, as there are too many variables: the task, problem domain, hardware, quality of implementations, and many other factors. You'll have run tests on your scenario to determine the the difference in performance, and then decide whether it is worth the the additional effort and complexity.

This is a very long and complex topic, but I feel it's worth mentioning for the sake of completeness that C#'s runtime optimizer is excellent, and is able to perform certain dynamic optimizations at runtime that are simply not available to C++ with its compile-time (static) optimizer. Even with this, the advantage is still typically deeply in the native application's court, but the dynamic optimizer is the reason for the "almost certainly" qualifier given above.

In terms of relative performance, I was also disturbed by the figures and discussions I saw in some other answers, so I thought I'd chime in and at the same time, provide some support for the statements I've made above.

A huge part of the problem with those benchmarks is you can't write C++ code as if you were writing C# and expect to get representative results (eg. performing thousands of memory allocations in C++ is going to give you terrible numbers.)

Instead, I wrote slightly more idiomatic C++ code and compared against the C# code @Wiory provided. The two major changes I made to the C++ code were:

1) used vector::reserve()

2) flattened the 2d array to 1d to achieve better cache locality (contiguous block)

C# (.NET 4.6.1)

private static void TestArray()
{
    const int rows = 5000;
    const int columns = 9000;
    DateTime t1 = System.DateTime.Now;
    double[][] arr = new double[rows][];
    for (int i = 0; i < rows; i++)
        arr[i] = new double[columns];
    DateTime t2 = System.DateTime.Now;

    Console.WriteLine(t2 - t1);

    t1 = System.DateTime.Now;
    for (int i = 0; i < rows; i++)
        for (int j = 0; j < columns; j++)
            arr[i][j] = i;
    t2 = System.DateTime.Now;

    Console.WriteLine(t2 - t1);
}

Run time (Release): Init: 124ms, Fill: 165ms

C++14 (Clang v3.8/C2)

#include <iostream>
#include <vector>

auto TestSuite::ColMajorArray()
{
    constexpr size_t ROWS = 5000;
    constexpr size_t COLS = 9000;

    auto initStart = std::chrono::steady_clock::now();

    auto arr = std::vector<double>();
    arr.reserve(ROWS * COLS);

    auto initFinish = std::chrono::steady_clock::now();
    auto initTime = std::chrono::duration_cast<std::chrono::microseconds>(initFinish - initStart);

    auto fillStart = std::chrono::steady_clock::now();

    for(auto i = 0, r = 0; r < ROWS; ++r)
    {
        for (auto c = 0; c < COLS; ++c)
        {
            arr[i++] = static_cast<double>(r * c);
        }
    }

    auto fillFinish = std::chrono::steady_clock::now();
    auto fillTime = std::chrono::duration_cast<std::chrono::milliseconds>(fillFinish - fillStart);

    return std::make_pair(initTime, fillTime);
}

Run time (Release): Init: 398µs (yes, that's microseconds), Fill: 152ms

Total Run times: C#: 289ms, C++ 152ms (roughly 90% faster)

Observations

• Changing the C# implementation to the same 1d array implementation yielded Init: 40ms, Fill: 171ms, Total: 211ms (C++ was still almost 40% faster).

• It is much harder to design and write "fast" code in C++ than it is to write "regular" code in either language.

• It's (perhaps) astonishingly easy to get poor performance in C++; we saw that with unreserved vectors performance. And there are lots of pitfalls like this.

• C#'s performance is rather amazing when you consider all that is going on at runtime. And that performance is comparatively easy to access.

• More anecdotal data comparing the performance of C++ and C#: https://benchmarksgame.alioth.debian.org/u64q/compare.php?lang=gpp&lang2=csharpcore

The bottom line is that C++ gives you much more control over performance. Do you want to use a pointer? A reference? Stack memory? Heap? Dynamic polymorphism or eliminate the runtime overhead of a vtable with static polymorphism (via templates/CRTP)? In C++ you have to... er, get to make all these choices (and more) yourself, ideally so that your solution best addresses the problem you're tackling.

Ask yourself if you actually want or need that control, because even for the trivial example above, you can see that although there is a significant improvement in performance, it requires a deeper investment to access.

Here's a flowchart based on this answer. See also, using script to emulate a terminal.

I know this is a late reply but maybe it can help someone.

Removing whitespace can be done by using the trim() function. After that if you want to sort the array with case sensitive manner you can just use:

Arrays.sort(yourArray);

and for case insensitive manner:

Arrays.sort(yourArray,String.CASE_INSENSITIVE_ORDER);

Hope this helps!

you can use just javascript for it

var total =10.8
(total).toFixed(2); 10.80


alert(total.toFixed(2))); 

let phone = "tel://\("1234567890")";
let url:NSURL = NSURL(string:phone)!;
UIApplication.sharedApplication().openURL(url);

Made it into a function. You can now call splitCsv <Filename> [chunkSize]

splitCsv() {
    HEADER=$(head -1 $1)
    if [ -n "$2" ]; then
        CHUNK=$2
    else 
        CHUNK=1000
    fi
    tail -n +2 $1 | split -l $CHUNK - $1_split_
    for i in $1_split_*; do
        sed -i -e "1i$HEADER" "$i"
    done
}

In addition to the previous replies, I would like to introduce another function.

numpy.random.shuffle as well as random.shuffle perform in-place shuffling. However, if you want to return a shuffled array numpy.random.permutation is the function to use.

java.io.NotSerializableException can occur when you serialize an inner class instance because:

serializing such an inner class instance will result in serialization of its associated outer class instance as well

Serialization of inner classes (i.e., nested classes that are not static member classes), including local and anonymous classes, is strongly discouraged

Your problem is that String JSON = "http://www.json-generator.com/j/cglqaRcMSW?indent=4"; is not JSON.
What you want to do is open an HTTP connection to "http://www.json-generator.com/j/cglqaRcMSW?indent=4" and parse the JSON response.

String JSON = "http://www.json-generator.com/j/cglqaRcMSW?indent=4";
JSONObject jsonObject = new JSONObject(JSON); // <-- Problem here!

Will not open a connection to the site and retrieve the content.

There's an alternative answer now in iOS 6, which is to set attributedText on the label, using an NSAttributedString with the appropriate paragraph styles. See this stack overflow answer for details on line height with NSAttributedString:

Core Text - NSAttributedString line height done right?

No.

But how about:

Business Intelligence Development Studio is Microsoft Visual Studio 2008 with additional project types that are specific to SQL Server business intelligence. Business Intelligence Development Studio is the primary environment that you will use to develop business solutions that include Analysis Services, Integration Services, and Reporting Services projects. Each project type supplies templates for creating the objects required for business intelligence solutions, and provides a variety of designers, tools, and wizards to work with the objects.

If you already have Visual Studio installed, the new project types will be installed along with SQL Server.

More Information

I had the same problem

I fixed that by using two options

contentType: false
processData: false

Actually I Added these two command to my $.ajax({}) function

Old I know, but sometimes I like this:

function addDays(days) {
    return new Date(Date.now() + 864e5 * days);
}

The __import__ function can be a bit hard to understand.

If you change

i = __import__('matplotlib.text')

to

i = __import__('matplotlib.text', fromlist=[''])

then i will refer to matplotlib.text.

In Python 2.7 and Python 3.1 or later, you can use importlib:

import importlib

i = importlib.import_module("matplotlib.text")

Some notes

• If you're trying to import something from a sub-folder e.g. ./feature/email.py, the code will look like importlib.import_module("feature.email")

• You can't import anything if there is no __init__.py in the folder with file you are trying to import

You can skip the container or background image with pure css arrow:

select {

  /* make arrow and background */

  background:
    linear-gradient(45deg, transparent 50%, blue 50%),
    linear-gradient(135deg, blue 50%, transparent 50%),
    linear-gradient(to right, skyblue, skyblue);
  background-position:
    calc(100% - 21px) calc(1em + 2px),
    calc(100% - 16px) calc(1em + 2px),
    100% 0;
  background-size:
    5px 5px,
    5px 5px,
    2.5em 2.5em;
  background-repeat: no-repeat;

  /* styling and reset */

  border: thin solid blue;
  font: 300 1em/100% "Helvetica Neue", Arial, sans-serif;
  line-height: 1.5em;
  padding: 0.5em 3.5em 0.5em 1em;

  /* reset */

  border-radius: 0;
  margin: 0;      
  -webkit-box-sizing: border-box;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  -webkit-appearance:none;
  -moz-appearance:none;

From what I understand, Python lists are already quite similar to ArrayLists. But if you want to tweak those parameters I found this post on the Internet that may be interesting (basically, just create your own ScalableList extension):

http://mail.python.org/pipermail/python-list/2000-May/035082.html

for i in range (1,10):
    string="string"+str(i)

To get string0, string1 ..... string10, you could do like

>>> ["string"+str(i) for i in range(11)]
['string0', 'string1', 'string2', 'string3', 'string4', 'string5', 'string6', 'string7', 'string8', 'string9', 'string10']

The file name should have .properties extension and the base directory should be in classpath. Otherwise it can also be in a jar which is in classpath Relative to the directory in classpath the resource bundle can be specified with / or . separator. "." is preferred.

Under the Tools menu in Visual Studio 2008 (or 2005 if you have the right WCF stuff installed) there is an options called 'WCF Service Configuration Editor'.

From there you can change the binding options for both the client and the services, one of these options will be for time-outs.

Then I run this command, it's gone:

The following method doesn't require root and should work anywhere (according to docs, even on Android Q+, if you keep targetSdkVersion = 28).

1. Make a blank app.

2. Create a ContentProvider:

   class ApiProvider : ContentProvider() {
   
       private val wifiManager: WifiManager? by lazy(LazyThreadSafetyMode.NONE) {
           requireContext().getSystemService(WIFI_SERVICE) as WifiManager?
       }
   
       private fun requireContext() = checkNotNull(context)
   
       private val matcher = UriMatcher(UriMatcher.NO_MATCH).apply {
           addURI("wifi", "enable", 0)
           addURI("wifi", "disable", 1)
       }
   
       override fun query(uri: Uri, projection: Array<out String>?, selection: String?, selectionArgs: Array<out String>?, sortOrder: String?): Cursor? {
           when (matcher.match(uri)) {
               0 -> {
                   enforceAdb()
                   withClearCallingIdentity {
                       wifiManager?.isWifiEnabled = true
                   }
               }
               1 -> {
                   enforceAdb()
                   withClearCallingIdentity {
                       wifiManager?.isWifiEnabled = false
                   }
               }
           }
           return null
       }
   
       private fun enforceAdb() {
           val callingUid = Binder.getCallingUid()
           if (callingUid != 2000 && callingUid != 0) {
               throw SecurityException("Only shell or root allowed.")
           }
       }
   
       private inline fun <T> withClearCallingIdentity(block: () -> T): T {
           val token = Binder.clearCallingIdentity()
           try {
               return block()
           } finally {
               Binder.restoreCallingIdentity(token)
           }
       }
   
       override fun onCreate(): Boolean = true
   
       override fun insert(uri: Uri, values: ContentValues?): Uri? = null
   
       override fun update(uri: Uri, values: ContentValues?, selection: String?, selectionArgs: Array<out String>?): Int = 0
   
       override fun delete(uri: Uri, selection: String?, selectionArgs: Array<out String>?): Int = 0
   
       override fun getType(uri: Uri): String? = null
   }
   

3. Declare it in AndroidManifest.xml along with necessary permission:

   <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
   
   <application>
   
       <provider
           android:name=".ApiProvider"
           android:authorities="wifi"
           android:exported="true" />
   </application>
   

4. Build the app and install it.

5. Call from ADB:

   adb shell content query --uri content://wifi/enable
   adb shell content query --uri content://wifi/disable
   

6. Make a batch script/shell function/shell alias with a short name that calls these commands.

Depending on your device you may need additional permissions.

Change the action URL of a form:

 <form id="myForm" action="">

     <button onclick="changeAction()">Try it</button>

 </form>

 <script>
     function changeAction() {

         document.getElementById("myForm").action = "url/action_page.php";
     }
 </script>

var list = new List<string>();
var queryable = list.AsQueryable();

The answer by Vijey has a bit of a problem when you're using react-redux for state management and some of the parent components are 'connected' to the redux store. The activeClassName is applied to Link only when the page is refreshed, and is not dynamically applied as the current route changes.

This is to do with the react-redux's connect function, as it suppresses context updates. To disable suppression of context updates, you can set pure: false when calling the connect() method like this:

//your component which has the custom NavLink as its child. 
//(this component may be the any component from the list of 
//parents and grandparents) eg., header

function mapStateToProps(state) {
  return { someprops: state.someprops }
}

export default connect(mapStateToProps, null, null, {
  pure: false
})(Header);

Check the issue here: reactjs#470

Check pure: false documentation here: docs

               @Override
               public void run() {
                   //code
               }
            };

        this.handler.postDelayed(this.yourRunnable, 2000);
       }


     @Override
  protected void onDestroy() {
      // to avoid memory leaks
      this.handler.removeCallbacks(this.yourRunnable);
      }
    }

And to be double sure you can be combined it with the "static class" method as described in the tronman answer

var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";

sttr1.search(str2);

it will return the position of the match, or -1 if it isn't found.

I had this problem but the cause was very different to scenarios reported above. My site was working everywhere except on my older Android (2.2). Turned out this device was rejecting the https certificate at the code.jquery.com CDN, so it was not loading JQuery. The fix was to load JQuery resources from the https Google CDN instead (using URLs named by others above).

The only way is to use a formula or to format cells. The method i will use will be the following: Add another column next to these values. Then use the following formula:

=HOUR(A1)*60+MINUTE(A1)+SECOND(A1)/60

If MouseEvent.offsetX is supported by your browser (all major browsers actually support it), The jQuery Event object will contain this property.

The MouseEvent.offsetX read-only property provides the offset in the X coordinate of the mouse pointer between that event and the padding edge of the target node.

$("#seek-bar").click(function(event) {
  var x = event.offsetX
  alert(x);    
});

The (very) short answer to your question is that paintComponent is called "when it needs to be." Sometimes it's easier to think of the Java Swing GUI system as a "black-box," where much of the internals are handled without too much visibility.

There are a number of factors that determine when a component needs to be re-painted, ranging from moving, re-sizing, changing focus, being hidden by other frames, and so on and so forth. Many of these events are detected auto-magically, and paintComponent is called internally when it is determined that that operation is necessary.

I've worked with Swing for many years, and I don't think I've ever called paintComponent directly, or even seen it called directly from something else. The closest I've come is using the repaint() methods to programmatically trigger a repaint of certain components (which I assume calls the correct paintComponent methods downstream.

In my experience, paintComponent is rarely directly overridden. I admit that there are custom rendering tasks that require such granularity, but Java Swing does offer a (fairly) robust set of JComponents and Layouts that can be used to do much of the heavy lifting without having to directly override paintComponent. I guess my point here is to make sure that you can't do something with native JComponents and Layouts before you go off trying to roll your own custom-rendered components.

JavaScript:

<script type="text/javascript">
    $(function() { 
        var url = window.location;
        $('ul.nav a').filter(function() {
            return this.href == url;
        }).parent().parent().parent().addClass('active');
    });   
</script>

CSS:

.active{
    color: #fff;
    background-color: #080808;
}

HTML:

<ul class="nav navbar-nav">
                        <li class="dropdown">
                            <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="true"><i class="glyphicon glyphicon-user icon-white"></i> MY ACCOUNT <span class="caret"></span></a>
                            <ul class="dropdown-menu" role="menu">
                                <li>
                                    <?php echo anchor('myaccount', 'HOME', 'title="HOME"'); ?>
                                </li>
                                <li>
                                    <?php echo anchor('myaccount/credithistory', 'CREDIT HISTORY', 'title="CREDIT HISTORY"'); ?>
                                </li>
                          </ul>
                     </li>
</ul>

There are a couple of things to check:

• In FireBug, see if there are any loading errors that would indicate that your script is badly formatted and the functions do not get registered.
• You can also try typing "proceedToSecond" into the FireBug console to see if the function gets defined
• One thing you may try is removing the space around the @type attribute to the script tag: it should be <script type="text/javascript"> instead of <script type = "text/javascript">

Try this one:

Color color = new Color (10,10,10)


myPaint.setColor(color.getRGB());

Wow! Mean this that you must learn a different programming language just to send two keys to the keyboard? There are simpler ways for you to achieve the same thing. :-)

The Batch file below is an example that start another program (cmd.exe in this case), send a command to it and then send an Up Arrow key, that cause to recover the last executed command. The Batch file is simple enough to be understand with no problems, so you may modify it to fit your needs.

@if (@CodeSection == @Batch) @then


@echo off

rem Use %SendKeys% to send keys to the keyboard buffer
set SendKeys=CScript //nologo //E:JScript "%~F0"

rem Start the other program in the same Window
start "" /B cmd

%SendKeys% "echo off{ENTER}"

set /P "=Wait and send a command: " < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "echo Hello, world!{ENTER}"

set /P "=Wait and send an Up Arrow key: [" < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "{UP}"

set /P "=] Wait and send an Enter key:" < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "{ENTER}"

%SendKeys% "exit{ENTER}"

goto :EOF


@end


// JScript section

var WshShell = WScript.CreateObject("WScript.Shell");
WshShell.SendKeys(WScript.Arguments(0));

For a list of key names for SendKeys, see: http://msdn.microsoft.com/en-us/library/8c6yea83(v=vs.84).aspx

For example:

LEFT ARROW    {LEFT}
RIGHT ARROW   {RIGHT}

Yes, take a look at getting a list of threads. Lots of examples on that page.

That's to do it programmatically. If you just want a list on Linux at least you can just use this command:

kill -3 processid

and the VM will do a thread dump to stdout.

SELECT
  student.firstname,
  student.lastname,
  exam.name,
  exam.date,
  grade.grade
FROM grade
 INNER JOIN student
   ON student.studentId = grade.fk_studentId
 INNER JOIN exam
   ON exam.examId = grade.fk_examId
 GROUP BY grade.gradeId
 ORDER BY exam.date

This will happen if you use a different version of the apk than the one in the google play.

To expand on Sandip’s answer, I had a bunch of strings showing up in the logs that were mis-coded in bit.ly. They meant to code just the URL but put a twitter handle and some other stuff after a space. It looked like this

? productID =26%20via%20@LFS

Normally, that would‘t be a problem, but I’m getting a lot of SQL injection attempts, so I redirect anything that isn’t a valid ID to a 404. I used the preg_replace method to make the invalid productID string into a valid productID.

$productID=preg_replace('/[\s]+.*/','',$productID);

I look for a space in the URL and then remove everything after it.

Besides just converting the types, you should also be conscious about the string's actual format.

When compiling for Multi-byte Character set Visual Studio and the Win API assumes UTF8 (Actually windows encoding which is Windows-28591 ).
When compiling for Unicode Character set Visual studio and the Win API assumes UTF16.

So, you must convert the string from UTF16 to UTF8 format as well, and not just convert to std::string.
This will become necessary when working with multi-character formats like some non-latin languages.

The idea is to decide that std::wstring always represents UTF16.
And std::string always represents UTF8.

This isn't enforced by the compiler, it's more of a good policy to have. Note the string prefixes I use to define UTF16 (L) and UTF8 (u8).

To convert between the 2 types, you should use: std::codecvt_utf8_utf16< wchar_t>

#include <string>

#include <codecvt>

int main()
{

    std::string original8 = u8"???";

    std::wstring original16 = L"???";

    //C++11 format converter
    std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>> convert;

    //convert to UTF8 and std::string
    std::string utf8NativeString = convert.to_bytes(original16);

    std::wstring utf16NativeString = convert.from_bytes(original8);

    assert(utf8NativeString == original8);
    assert(utf16NativeString == original16);

    return 0;
}

With bash :

a=abcdefghij    
for ((i=0;i<${#a};i++));do printf %02X \'${a:$i:1};done

6162636465666768696A

I use:

from pathlib import Path
import platform
import tempfile

tempdir = Path("/tmp" if platform.system() == "Darwin" else tempfile.gettempdir())

This is because on MacOS, i.e. Darwin, tempfile.gettempdir() and os.getenv('TMPDIR') return a value such as '/var/folders/nj/269977hs0_96bttwj2gs_jhhp48z54/T'; it is one that I do not always want.

Another way to pass named parameters to Bash... is passing by reference. This is supported as of Bash 4.0

#!/bin/bash
function myBackupFunction(){ # directory options destination filename
local directory="$1" options="$2" destination="$3" filename="$4";
  echo "tar cz ${!options} ${!directory} | ssh root@backupserver \"cat > /mnt/${!destination}/${!filename}.tgz\"";
}

declare -A backup=([directory]=".." [options]="..." [destination]="backups" [filename]="backup" );

myBackupFunction backup[directory] backup[options] backup[destination] backup[filename];

An alternative syntax for Bash 4.3 is using a nameref.

Although the nameref is a lot more convenient in that it seamlessly dereferences, some older supported distros still ship an older version, so I won't recommend it quite yet.

Both rebase (and cherry-pick) and merge have their advantages and disadvantages. I argue for merge here, but it's worth understanding both. (Look here for an alternate, well-argued answer enumerating cases where rebase is preferred.)

merge is preferred over cherry-pick and rebase for a couple of reasons.

1. Robustness. The SHA1 identifier of a commit identifies it not just in and of itself but also in relation to all other commits that precede it. This offers you a guarantee that the state of the repository at a given SHA1 is identical across all clones. There is (in theory) no chance that someone has done what looks like the same change but is actually corrupting or hijacking your repository. You can cherry-pick in individual changes and they are likely the same, but you have no guarantee. (As a minor secondary issue the new cherry-picked commits will take up extra space if someone else cherry-picks in the same commit again, as they will both be present in the history even if your working copies end up being identical.)
2. Ease of use. People tend to understand the merge workflow fairly easily. rebase tends to be considered more advanced. It's best to understand both, but people who do not want to be experts in version control (which in my experience has included many colleagues who are damn good at what they do, but don't want to spend the extra time) have an easier time just merging.

Even with a merge-heavy workflow rebase and cherry-pick are still useful for particular cases:

1. One downside to merge is cluttered history. rebase prevents a long series of commits from being scattered about in your history, as they would be if you periodically merged in others' changes. That is in fact its main purpose as I use it. What you want to be very careful of, is never to rebase code that you have shared with other repositories. Once a commit is pushed someone else might have committed on top of it, and rebasing will at best cause the kind of duplication discussed above. At worst you can end up with a very confused repository and subtle errors it will take you a long time to ferret out.
2. cherry-pick is useful for sampling out a small subset of changes from a topic branch you've basically decided to discard, but realized there are a couple of useful pieces on.

As for preferring merging many changes over one: it's just a lot simpler. It can get very tedious to do merges of individual changesets once you start having a lot of them. The merge resolution in git (and in Mercurial, and in Bazaar) is very very good. You won't run into major problems merging even long branches most of the time. I generally merge everything all at once and only if I get a large number of conflicts do I back up and re-run the merge piecemeal. Even then I do it in large chunks. As a very real example I had a colleague who had 3 months worth of changes to merge, and got some 9000 conflicts in 250000 line code-base. What we did to fix is do the merge one month's worth at a time: conflicts do not build up linearly, and doing it in pieces results in far fewer than 9000 conflicts. It was still a lot of work, but not as much as trying to do it one commit at a time.

Enable the two options

Simple Import os package and run below command.

import os
os.system("python test.py")

Yes, python strings are immutable and any modification will result in creating a new string. This is how it's mostly done.

So, go ahead with it.

Maybe useful for anyone else running into this issue: When setting the port on the properties:

props.put("mail.smtp.port", smtpPort);

..make sure to use a string object. Using a numeric (ie Long) object will cause this statement to seemingly have no effect.

Run this

    for (Method m : sex.class.getDeclaredMethods()) {
        System.out.println(m);
    }

you will see

public static test.Sex test.Sex.valueOf(java.lang.String)
public static test.Sex[] test.Sex.values()

These are all public methods that "sex" class has. They are not in the source code, javac.exe added them

Notes:

1. never use sex as a class name, it's difficult to read your code, we use Sex in Java

2. when facing a Java puzzle like this one, I recommend to use a bytecode decompiler tool (I use Andrey Loskutov's bytecode outline Eclispe plugin). This will show all what's inside a class

ps if it is only about space in the input, then some double quotes worked smoothly for me...

read artist;

find "/mnt/2tb_USB_hard_disc/p_music/$artist" -type f -name *.mp3 -exec mpg123 '{}' \;

Considering filter:expression is a Microsoft extension to CSS, so it will only work in Internet Explorer. If you want to grey it out, I would recommend that you set it's opacity to 50% using a bit of javascript.

http://lyxus.net/mv would be a good place to start, because it discusses an opacity script that works with Firefox, Safari, KHTML, Internet Explorer and CSS3 capable browsers.

You might also want to give it a grey border.

I'm not sure if this has been said previously, or if it's what is needed here, but couldn't you make the string an array and then find the length?

let randomString = "Random String";

let stringWords = randomString.split(' ');
console.log(stringWords.length);

If you are using WAMP...

you should add or uncomment the property always_populate_raw_post_data in php.ini and set its value to -1. In my case php.ini is located in:

C:\wamp64\bin\php\php5.6.25\php.ini

..but if you are still getting the warning (as I was)

You should also set always_populate_raw_post_data = -1 in phpForApache.ini:

C:\wamp64\bin\php\php5.6.25\phpForApache.ini

If you can't find this file, open a browser window and go to:

http://localhost/?phpinfo=1

and look for the value of Loaded Configuration File key. In my case the php.ini used by WAMP is located in:

C:\wamp64\bin\apache\apache2.4.23\bin\php.ini (symlink to C:\wamp64\bin\php\php5.6.25\phpForApache.ini)

Finally restart WAMP (or click restart all services)

If you want to include a time frame in the future, with the current year (e.g. 2017) as the start year so that next year it’ll appear like this: “© 2017-2018, Company.”, then use the following code. It’ll automatically update each year:

&copy; Copyright 2017<script>new Date().getFullYear()>2017&&document.write("-"+new Date().getFullYear());</script>, Company.

© Copyright 2017-2018, Company.

But if the first year has already passed, the shortest code can be written like this:

&copy; Copyright 2010-<script>document.write(new Date().getFullYear())</script>, Company.

From the documentation:

Named exports are useful to export several values. During the import, one will be able to use the same name to refer to the corresponding value.

Concerning the default export, there is only a single default export per module. A default export can be a function, a class, an object or anything else. This value is to be considered as the "main" exported value since it will be the simplest to import.

Its very easy and simple. Do this

from dateutil.relativedelta import relativedelta
from datetime import datetime

today_date = datetime.today()
print "todays date time: %s" %today_date

one_month_ago = today_date - relativedelta(months=1)
print "one month ago date time: %s" % one_month_ago
print "one month ago date: %s" % one_month_ago.date()

Here is the output: $python2.7 main.py

todays date time: 2016-09-06 02:13:01.937121
one month ago date time: 2016-08-06 02:13:01.937121
one month ago date: 2016-08-06

function chunkString(str, length = 10) {
    let result = [],
        offset = 0;
    if (str.length <= length) return result.push(str) && result;
    while (offset < str.length) {
        result.push(str.substr(offset, length));
        offset += length;
    }
    return result;
}

PowerShell 3 has the $PSScriptRoot automatic variable:

Contains the directory from which a script is being run.

In Windows PowerShell 2.0, this variable is valid only in script modules (.psm1). Beginning in Windows PowerShell 3.0, it is valid in all scripts.

Don't be fooled by the poor wording. PSScriptRoot is the directory of the current file.

In PowerShell 2, you can calculate the value of $PSScriptRoot yourself:

# PowerShell v2
$PSScriptRoot = Split-Path -Parent -Path $MyInvocation.MyCommand.Definition

As mentioned in Jonathan's answer, FETCH_HEAD corresponds to the file .git/FETCH_HEAD. Typically, the file will look like this:

71f026561ddb57063681109aadd0de5bac26ada9                        branch 'some-branch' of <remote URL>
669980e32769626587c5f3c45334fb81e5f44c34        not-for-merge   branch 'some-other-branch' of <remote URL>
b858c89278ab1469c71340eef8cf38cc4ef03fed        not-for-merge   branch 'yet-some-other-branch' of <remote URL>

Note how all branches but one are marked not-for-merge. The odd one out is the branch that was checked out before the fetch. In summary: FETCH_HEAD essentially corresponds to the remote version of the branch that's currently checked out.

The REST API for Dropbox, Twitter, Google Web Services and Facebook all uses underscores.

basename($_SERVER['REQUEST_URI']) returns everything after and including the '?',

In my code sometimes I need only sections, so separate it out so I can get the value of what I need on the fly. Not sure on the performance speed compared to other methods, but it's really useful for me.

Deleting Branches

Let's assume our work on branch "contact-form" is done and we've already integrated it into "master". Since we don't need it anymore, we can delete it (locally):

$ git branch -d contact-form

And for deleting the remote branch:

git push origin --delete contact-form
