Assuming you can only have one 'something1' or 'something2', etc. per line, you can use a lookup table:

$lookupTable = @{
    'something1' = 'something1aa'
    'something2' = 'something2bb'
    'something3' = 'something3cc'
    'something4' = 'something4dd'
    'something5' = 'something5dsf'
    'something6' = 'something6dfsfds'
}

$original_file = 'path\filename.abc'
$destination_file =  'path\filename.abc.new'

Get-Content -Path $original_file | ForEach-Object {
    $line = $_

    $lookupTable.GetEnumerator() | ForEach-Object {
        if ($line -match $_.Key)
        {
            $line -replace $_.Key, $_.Value
            break
        }
    }
} | Set-Content -Path $destination_file

If you can have more than one of those, just remove the break in the if statement.

For the benefit of any future visitors who may have missed my comments:

br {
    border-bottom:1px dashed black;
}

does not work.

It has been tested in IE 6, 7 & 8, Firefox 2, 3 & 3.5B4, Safari 3 & 4 for Windows, Opera 9.6 & 10 (alpha) and Google Chrome (version 2) and it didn't work in any of them. If at some point in the future someone finds a browser that does support a border on a <br> element, please feel free to update this list.

Also note that I tried a number of other things:

br {
    border-bottom:1px dashed black;
    display:block;
}

br:before { /* and :after */
    border-bottom:1px dashed black;
    /* content and display added as per porneL's comment */
    content: "";
    display: block;
}

br { /* and :before and :after */
    content: url(a_dashed_line_image);
}

Of those, the following does works in Opera 9.6 and 10 (alpha) (thanks porneL!):

br:after {
    border-bottom:1px dashed black;
    content: "";
    display: block;
}

Not very useful when it is only supported in one browser, but I always find it interesting to see how different browsers implement the specification.

>>> x = "2342.34"
>>> float(x)
2342.3400000000001

There you go. Use float (which behaves like and has the same precision as a C,C++, or Java double).

hey guys i think what you are looking for is this one using select command. With this you can specify a RANGE GREATER THAN(>) OR LESSER THAN(<) IN MySQL WITH THIS:::::

select* from <**TABLE NAME**> where year(**COLUMN NAME**) > **DATE** OR YEAR(COLUMN NAME )< **DATE**;

FOR EXAMPLE:

select name, BIRTH from pet1 where year(birth)> 1996 OR YEAR(BIRTH)< 1989;
+----------+------------+
| name     | BIRTH      |
+----------+------------+
| bowser   | 1979-09-11 |
| chirpy   | 1998-09-11 |
| whistler | 1999-09-09 |
+----------+------------+

FOR SIMPLE RANGE LIKE USE ONLY GREATER THAN / LESSER THAN

mysql> select COLUMN NAME from <TABLE NAME> where year(COLUMN NAME)> 1996;

FOR EXAMPLE mysql>

select name from pet1 where year(birth)> 1996 OR YEAR(BIRTH)< 1989;
+----------+
| name     |
+----------+
| bowser   |
| chirpy   |
| whistler |
+----------+
3 rows in set (0.00 sec)

Split the text into lines, and draw each separately:

function fillTextMultiLine(ctx, text, x, y) {
  var lineHeight = ctx.measureText("M").width * 1.2;
  var lines = text.split("\n");
  for (var i = 0; i < lines.length; ++i) {
    ctx.fillText(lines[i], x, y);
    y += lineHeight;
  }
}

Another oh-so-easy mistake, which was the source of the problem for me: I’d written my own shouldComponentUpdate method, which didn’t check the new state change I’d added.

std::atomic exists because many ISAs have direct hardware support for it

What the C++ standard says about std::atomic has been analyzed in other answers.

So now let's see what std::atomic compiles to to get a different kind of insight.

The main takeaway from this experiment is that modern CPUs have direct support for atomic integer operations, for example the LOCK prefix in x86, and std::atomic basically exists as a portable interface to those intructions: What does the "lock" instruction mean in x86 assembly? In aarch64, LDADD would be used.

This support allows for faster alternatives to more general methods such as std::mutex, which can make more complex multi-instruction sections atomic, at the cost of being slower than std::atomic because std::mutex it makes futex system calls in Linux, which is way slower than the userland instructions emitted by std::atomic, see also: Does std::mutex create a fence?

Let's consider the following multi-threaded program which increments a global variable across multiple threads, with different synchronization mechanisms depending on which preprocessor define is used.

main.cpp

#include <atomic>
#include <iostream>
#include <thread>
#include <vector>

size_t niters;

#if STD_ATOMIC
std::atomic_ulong global(0);
#else
uint64_t global = 0;
#endif

void threadMain() {
    for (size_t i = 0; i < niters; ++i) {
#if LOCK
        __asm__ __volatile__ (
            "lock incq %0;"
            : "+m" (global),
              "+g" (i) // to prevent loop unrolling
            :
            :
        );
#else
        __asm__ __volatile__ (
            ""
            : "+g" (i) // to prevent he loop from being optimized to a single add
            : "g" (global)
            :
        );
        global++;
#endif
    }
}

int main(int argc, char **argv) {
    size_t nthreads;
    if (argc > 1) {
        nthreads = std::stoull(argv[1], NULL, 0);
    } else {
        nthreads = 2;
    }
    if (argc > 2) {
        niters = std::stoull(argv[2], NULL, 0);
    } else {
        niters = 10;
    }
    std::vector<std::thread> threads(nthreads);
    for (size_t i = 0; i < nthreads; ++i)
        threads[i] = std::thread(threadMain);
    for (size_t i = 0; i < nthreads; ++i)
        threads[i].join();
    uint64_t expect = nthreads * niters;
    std::cout << "expect " << expect << std::endl;
    std::cout << "global " << global << std::endl;
}

Conclusions:

• the non-atomic version saves the global to a register, and increments the register.

  Therefore, at the end, very likely four writes happen back to global with the same "wrong" value of 100000.

• std::atomic compiles to lock addq. The LOCK prefix makes the following inc fetch, modify and update memory atomically.

• our explicit inline assembly LOCK prefix compiles to almost the same thing as std::atomic, except that our inc is used instead of add. Not sure why GCC chose add, considering that our INC generated a decoding 1 byte smaller.

I saw some answers at this post and it's possible to be considered completed base knowledge, because have a several approaches in C# Programming to resolve the same problem. Only one thing that is necessary to be considered is about a difference between Pure UTF-8 and UTF-8 with B.O.M..

In last week, at my job, I need to develop one functionality that outputs CSV files with B.O.M. and other CSVs with pure UTF-8 (without B.O.M.), each CSV file Encoding type will be consumed by different non-standardized APIs, that one API read UTF-8 with B.O.M. and the other API read without B.O.M.. I need to research the references about this concept, reading "What's the difference between UTF-8 and UTF-8 without B.O.M.?" Stack Overflow discussion and this Wikipedia link "Byte order mark" to build my approach.

Finally, my C# Programming for the both UTF-8 encoding types (with B.O.M. and pure) needed to be similar like this example bellow:

//for UTF-8 with B.O.M., equals shared by Zanoni (at top)
string result = System.Text.Encoding.UTF8.GetString(byteArray);

//for Pure UTF-8 (without B.O.M.)
string result = (new UTF8Encoding(false)).GetString(byteArray);

For Swift 3.1, Swift 4 and Swift 5, if you only want change the font size for a label :

let myLabel : UILabel = ...
myLabel.font = myLabel.font.withSize(25)

$('#yourid').prop('disabled', true);

One solution could be to wrap the options inside optgroup:

optgroup { font-size:40px; }

<select>
  <optgroup>
    <option selected="selected" class="service-small">Service area?</option>
    <option class="service-small">Volunteering</option>
    <option class="service-small">Partnership &amp; Support</option>
    <option class="service-small">Business Services</option>
  </optgroup>
</select>

One way to programmatically "click" the button, if you have access to the source, is to simply call the button's OnClick event handler (or Execute the ICommand associated with the button, if you're doing things in the more WPF-y manner).

Why are you doing this? Are you doing some sort of automated testing, for example, or trying to perform the same action that the button performs from a different section of code?

In my case, the files were already copied, I found the easiest way to follow the steps in this guide: https://www.ryadel.com/en/exporting-importing-app-pools-and-websites-configuration-between-multiple-iis-instances/

I exported AppPools/Websites, copied the xml files to the destination server and Imported AppPools then Websites. Worked very well. This is also another excellent option for this question.

You could create Util class:

public final class CollectionHelpers {
    public static <T> boolean addNullSafe(List<T> list, T element) {
        if (list == null || element == null) {
            return false;
        }

        return list.add(element);
    }
}

And then use it:

Element element = getElementFromSomeWhere(someParameter);
List<Element> arrayList = new ArrayList<>();
CollectionHelpers.addNullSafe(list, element);

Operator + is a unary operator which converts value to number. Below I prepared a table with corresponding results of using this operator for different values.

+-----------------------------+-----------+
| Value                       | + (Value) |
+-----------------------------+-----------+
| 1                           | 1         |
| '-1'                        | -1        |
| '3.14'                      | 3.14      |
| '3'                         | 3         |
| '0xAA'                      | 170       |
| true                        | 1         |
| false                       | 0         |
| null                        | 0         |
| 'Infinity'                  | Infinity  |
| 'infinity'                  | NaN       |
| '10a'                       | NaN       |
| undefined                   | Nan       |
| ['Apple']                   | Nan       |
| function(val){ return val } | NaN       |
+-----------------------------+-----------+

Operator + returns value for objects which have implemented method valueOf.

let something = {
    valueOf: function () {
        return 25;
    }
};

console.log(+something);

all of the above are correct. Please be sure before that this is a number in a string by doing "typeot x === 'number'" other wise it will return NaN

 var num = "fsdfsdf242342";
 typeof num => 'string';

 var num1 = "12423";
 typeof num1 => 'number';
 +num1 = > 12423`

DATEPART(yyyy, date_column) could be used to extract year. In general, DATEPART function is used to extract specific portions of a date value.

no need for the padding or the corners.

here's a sample:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" >
    <gradient android:startColor="#FFFF0000" android:endColor="#80FF00FF"
        android:angle="270"/>
</shape>

based on :

https://stackoverflow.com/a/10104037/878126

$img_file='http://www.somedomain.com/someimage.jpg'

$img_file=file_get_contents($img_file);

$file_loc=$_SERVER['DOCUMENT_ROOT'].'/some_dir/test.jpg';

$file_handler=fopen($file_loc,'w');

if(fwrite($file_handler,$img_file)==false){
    echo 'error';
}

fclose($file_handler);

As indicated by the other answers, the error is to due to k = list[0:j], where your key is converted to a list. One thing you could try is reworking your code to take advantage of the split function:

# Using with ensures that the file is properly closed when you're done
with open('filename.txt', 'rb') as f:
  d = {}
  # Here we use readlines() to split the file into a list where each element is a line
  for line in f.readlines():
    # Now we split the file on `x`, since the part before the x will be
    # the key and the part after the value
    line = line.split('x')
    # Take the line parts and strip out the spaces, assigning them to the variables
    # Once you get a bit more comfortable, this works as well:
    # key, value = [x.strip() for x in line] 
    key = line[0].strip()
    value = line[1].strip()
    # Now we check if the dictionary contains the key; if so, append the new value,
    # and if not, make a new list that contains the current value
    # (For future reference, this is a great place for a defaultdict :)
    if key in d:
      d[key].append(value)
    else:
      d[key] = [value]

print d
# {'AAA': ['111', '112'], 'AAC': ['123'], 'AAB': ['111']}

Note that if you are using Python 3.x, you'll have to make a minor adjustment to get it work properly. If you open the file with rb, you'll need to use line = line.split(b'x') (which makes sure you are splitting the byte with the proper type of string). You can also open the file using with open('filename.txt', 'rU') as f: (or even with open('filename.txt', 'r') as f:) and it should work fine.

If you are within a fragment, then you also need to get the activity object as runOnUIThread is a method on the activity.

An example in Kotlin with some surrounding context to make it clearer - this example is navigating from a camera fragment to a gallery fragment:

// Setup image capture listener which is triggered after photo has been taken
imageCapture.takePicture(
       outputOptions, cameraExecutor, object : ImageCapture.OnImageSavedCallback {

           override fun onError(exc: ImageCaptureException) {
           Log.e(TAG, "Photo capture failed: ${exc.message}", exc)
        }

        override fun onImageSaved(output: ImageCapture.OutputFileResults) {
                        val savedUri = output.savedUri ?: Uri.fromFile(photoFile)
                        Log.d(TAG, "Photo capture succeeded: $savedUri")
               
             //Do whatever work you do when image is saved         
             
             //Now ask navigator to move to new tab - as this
             //updates UI do on the UI thread           
             activity?.runOnUiThread( {
                 Navigation.findNavController(
                        requireActivity(), R.id.fragment_container
                 ).navigate(CameraFragmentDirections
                        .actionCameraToGallery(outputDirectory.absolutePath))
              })

Some color-syntaxing enrichment can be applied with the following blockcode syntax

```json
Here goes your json object definition
```

Note: This won't prettify the json representation. To do so, one can previously rely on an external service such as jsbeautifier.org and paste the prettified result in the wiki.

There are lots of solutions:

b = Arrays.copyOf(a, a.length);

Which allocates a new array, copies over the elements of a, and returns the new array.

Or

b = new int[a.length];
System.arraycopy(a, 0, b, 0, b.length);

Which copies the source array content into a destination array that you allocate yourself.

Or

b = a.clone();

which works very much like Arrays.copyOf(). See this thread.

Or the one you posted, if you reverse the direction of the assignment in the loop:

b[i] = a[i]; // NOT a[i] = b[i];

Here are a few things you need to do:

1-Download the library if you haven't already done that.

2- Import into Eclipse.

3- Set you project to use the library: Project-> Properties -> Android -> Scroll down to Library section, click Add... and select viewpagerindicator.

4- Now you should be able to import com.viewpagerindicator.TitlePageIndicator.

Now about implementing this without using fragments:

In the sample that comes with viewpagerindicatior, you can see that the library is being used with a ViewPager which has a FragmentPagerAdapter.

But in fact the library itself is Fragment independant. It just needs a ViewPager. So just use a PagerAdapter instead of a FragmentPagerAdapter and you're good to go.

String path = "C:\\Documents and Settings\\Manoj\\Desktop";
path = path.replace("\\", "/");
// or
path = path.replaceAll("\\\\", "/");

Find more details in the Docs

You should inject $document in your controller, and use it instead of original document object.

var myElement = angular.element($document[0].querySelector('#MyID'))

If you don't need the jquery style element wrap, $document[0].querySelector('#MyID') will give you the DOM object.

this things is worked on laravel 5.1.

first, on your terminal execute this code

php artisan make:migration add_paid_to_users --table=users

after that go to your project directory and expand directory database - migration and edit file add_paid_to_users.php, add this code

public function up()
{
    Schema::table('users', function (Blueprint $table) {
         $table->string('paid'); //just add this line
    });
}

after that go back to your terminal and execute this command

php artisan migrate

hope this help.

To do this without any headache:

1. Check out what's the current branch in the gitrepo1 with git status, let's say branch "development".
2. Change directory to the newrepo, then git clone the project from repository.
3. Switch branch in newrepo to the previous one: git checkout development.
4. Syncronize newrepo with the older one, gitrepo1 using rsync, excluding .git folder: rsync -azv --exclude '.git' gitrepo1 newrepo/gitrepo1. You don't have to do this with rsync of course, but it does it so smooth.

The benefit of this approach: you are good to continue exactly where you left off: your older branch, unstaged changes, etc.

This would be equivalent to urlretrieve:

import urllib.request
data = urllib.request.urlretrieve("http://...")

urlretrieve behaves exactly the same way as it did in Python 2.x, so it'll work just fine.

Basically:

• urlretrieve saves the file to a temporary file and returns a tuple (filename, headers)
• urlopen returns a Request object whose read method returns a bytestring containing the file contents

Update: This answer is very old. gridExtra::grid.arrange() is now the recommended approach. I leave this here in case it might be useful.

Stephen Turner posted the arrange() function on Getting Genetics Done blog (see post for application instructions)

vp.layout <- function(x, y) viewport(layout.pos.row=x, layout.pos.col=y)
arrange <- function(..., nrow=NULL, ncol=NULL, as.table=FALSE) {
 dots <- list(...)
 n <- length(dots)
 if(is.null(nrow) & is.null(ncol)) { nrow = floor(n/2) ; ncol = ceiling(n/nrow)}
 if(is.null(nrow)) { nrow = ceiling(n/ncol)}
 if(is.null(ncol)) { ncol = ceiling(n/nrow)}
        ## NOTE see n2mfrow in grDevices for possible alternative
grid.newpage()
pushViewport(viewport(layout=grid.layout(nrow,ncol) ) )
 ii.p <- 1
 for(ii.row in seq(1, nrow)){
 ii.table.row <- ii.row 
 if(as.table) {ii.table.row <- nrow - ii.table.row + 1}
  for(ii.col in seq(1, ncol)){
   ii.table <- ii.p
   if(ii.p > n) break
   print(dots[[ii.table]], vp=vp.layout(ii.table.row, ii.col))
   ii.p <- ii.p + 1
  }
 }
}

You're trying to import all of those modules at once. Even if one of them fails, the rest will not import. For example:

try:
    import datetime
    import foo
    import sys
except ImportError:
    pass

Let's say foo doesn't exist. Then only datetime will be imported.

What you can do is import the sys module at the beginning of the file, before the try/except statement:

import sys
try:
    import numpy as np
    import pyfits as pf
    import scipy.ndimage as nd
    import pylab as pl
    import os
    import heapq
    from scipy.optimize import leastsq

except ImportError:
    print "Error: missing one of the libraries (numpy, pyfits, scipy, matplotlib)"
    sys.exit()

I found too simple hack just do this add new element in AndroidManifest as:-

<activity android:name=".activityName"
          android:label="@string/app_name"
          android:noHistory="true"/>

the android:noHistory will clear your unwanted activity from Stack.

I found the SimpleLogger from heiswayi on GitHub good.

If you're using Spring Boot, the simplest way to disable the Spring Security default headers is to use security.headers.* properties. In particular, if you want to disable the X-Frame-Options default header, just add the following to your application.properties:

security.headers.frame=false

There is also security.headers.cache, security.headers.content-type, security.headers.hsts and security.headers.xss properties that you can use. For more information, take a look at SecurityProperties.

extern "C" makes a function-name in C++ have C linkage (compiler does not mangle the name) so that client C code can link to (use) your function using a C compatible header file that contains just the declaration of your function. Your function definition is contained in a binary format (that was compiled by your C++ compiler) that the client C linker will then link to using the C name.

Since C++ has overloading of function names and C does not, the C++ compiler cannot just use the function name as a unique id to link to, so it mangles the name by adding information about the arguments. A C compiler does not need to mangle the name since you can not overload function names in C. When you state that a function has extern "C" linkage in C++, the C++ compiler does not add argument/parameter type information to the name used for linkage.

Just so you know, you can specify extern "C" linkage to each individual declaration/definition explicitly or use a block to group a sequence of declarations/definitions to have a certain linkage:

extern "C" void foo(int);
extern "C"
{
   void g(char);
   int i;
}

If you care about the technicalities, they are listed in section 7.5 of the C++03 standard, here is a brief summary (with emphasis on extern "C"):

• extern "C" is a linkage-specification
• Every compiler is required to provide "C" linkage
• A linkage specification shall occur only in namespace scope
• All function types, function names and variable names have a language linkage See Richard's Comment: Only function names and variable names with external linkage have a language linkage
• Two function types with distinct language linkages are distinct types even if otherwise identical
• Linkage specs nest, inner one determines the final linkage
• extern "C" is ignored for class members
• At most one function with a particular name can have "C" linkage (regardless of namespace)
• extern "C" forces a function to have external linkage (cannot make it static) See Richard's comment: static inside extern "C" is valid; an entity so declared has internal linkage, and so does not have a language linkage
• Linkage from C++ to objects defined in other languages and to objects defined in C++ from other languages is implementation-defined and language-dependent. Only where the object layout strategies of two language implementations are similar enough can such linkage be achieved

To fetch only current date excluding time stamp:

in lower versions, looks like hive CURRENT_DATE is not available, hence you can use (it worked for me on Hive 0.14)

select TO_DATE(FROM_UNIXTIME(UNIX_TIMESTAMP()));

In higher versions say hive 2.0, you can use :

select CURRENT_DATE;

The answer given above can't solve my problem.So I change async into false to get the alert message.

jQuery.ajax({
            type:"post",
            dataType:"json",
            async: false,
            url: myAjax.ajaxurl,
            data: {action: 'submit_data', info: info},
            success: function(data) {
                alert("Data was succesfully captured");
            },
        });

Always have handy the un-minified CSS for bootstrap so you can see what styles they have on their components, then create a CSS file AFTER it, if you don't use LESS and over-write their mixins or whatever

This is the default modal css for 768px and up:

@media (min-width: 768px) {
  .modal-dialog {
    width: 600px;
    margin: 30px auto;
  }
  ...
}

They have a class modal-lg for larger widths

@media (min-width: 992px) {
  .modal-lg {
    width: 900px;
  }
}

If you need something twice the 600px size, and something fluid, do something like this in your CSS after the Bootstrap css and assign that class to the modal-dialog.

@media (min-width: 768px) {
  .modal-xl {
    width: 90%;
   max-width:1200px;
  }
}

HTML

<div class="modal-dialog modal-xl">

Code snippet above provides incorrect byte order in string, so I fixed it a bit.

char const hex[16] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A',   'B','C','D','E','F'};

std::string byte_2_str(char* bytes, int size) {
  std::string str;
  for (int i = 0; i < size; ++i) {
    const char ch = bytes[i];
    str.append(&hex[(ch  & 0xF0) >> 4], 1);
    str.append(&hex[ch & 0xF], 1);
  }
  return str;
}

Use AES.

In more details:

• DES is the old "data encryption standard" from the seventies. Its key size is too short for proper security (56 effective bits; this can be brute-forced, as has been demonstrated more than ten years ago). Also, DES uses 64-bit blocks, which raises some potential issues when encrypting several gigabytes of data with the same key (a gigabyte is not that big nowadays).
• 3DES is a trick to reuse DES implementations, by cascading three instances of DES (with distinct keys). 3DES is believed to be secure up to at least "2¹¹²" security (which is quite a lot, and quite far in the realm of "not breakable with today's technology"). But it is slow, especially in software (DES was designed for efficient hardware implementation, but it sucks in software; and 3DES sucks three times as much).
• Blowfish is a block cipher proposed by Bruce Schneier, and deployed in some softwares. Blowfish can use huge keys and is believed secure, except with regards to its block size, which is 64 bits, just like DES and 3DES. Blowfish is efficient in software, at least on some software platforms (it uses key-dependent lookup tables, hence performance depends on how the platform handles memory and caches).
• AES is the successor of DES as standard symmetric encryption algorithm for US federal organizations (and as standard for pretty much everybody else, too). AES accepts keys of 128, 192 or 256 bits (128 bits is already very unbreakable), uses 128-bit blocks (so no issue there), and is efficient in both software and hardware. It was selected through an open competition involving hundreds of cryptographers during several years. Basically, you cannot have better than that.

So, when in doubt, use AES.

Note that a block cipher is a box which encrypts "blocks" (128-bit chunks of data with AES). When encrypting a "message" which may be longer than 128 bits, the message must be split into blocks, and the actual way you do the split is called the mode of operation or "chaining". The naive mode (simple split) is called ECB and has issues. Using a block cipher properly is not easy, and it is more important than selecting between, e.g., AES or 3DES.

Could you also do

$(input[type=file]).val()

Create an extension method?

Console.WriteLine(value.ToGBString());

// ...

public static class DoubleExtensions
{
    public static string ToGBString(this double value)
    {
        return value.ToString(CultureInfo.GetCultureInfo("en-GB"));
    }
}

this works wonders - no its turn to call this procedure form code with DataTable with schema exactly matching the custType create table customer ( id int identity(1,1) primary key, name varchar(50), cnt varchar(10) )

 insert into customer values('y1', 'c1')
 insert into customer values('y2', 'c2')
 insert into customer values('y3', 'c3')

 insert into customer values('y5', 'c5')

 declare @ct as custType 
 insert @ct (ctid, ctName) values(3, 'y33'), (4, 'y44')
 exec multiUpdate @ct

 create Proc multiUpdate (@ct custType readonly) as begin
 update customer set  Name = t.ctName  from @ct t where t.ctId = customer.id
 end

public DataTable UpdateLevels(DataTable dt)
        {
            DataTable dtRet = new DataTable();
            using (SqlConnection con = new SqlConnection(datalayer.bimCS))
            {
                SqlCommand command = new SqlCommand();
                command.CommandText = "UpdateLevels";
                command.Parameters.Clear();
                command.CommandType = CommandType.StoredProcedure;
                command.Parameters.AddWithValue("@ct", dt).SqlDbType = SqlDbType.Structured;
                command.Connection = con;
                using (SqlDataAdapter dataAdapter = new SqlDataAdapter(command))
                {
                    dataAdapter.SelectCommand = command;

                }

Usually StaleElementReferenceException when element we try to access has appeared but other elements may affect the position of element we are intrested in hence when we try to click or getText or try to do some action on WebElement we get exception which usually says element not attached with DOM.

Solution I tried is as follows:

 protected void clickOnElement(By by) {
        try {
            waitForElementToBeClickableBy(by).click();
        } catch (StaleElementReferenceException e) {
            for (int attempts = 1; attempts < 100; attempts++) {
                try {
                    waitFor(500);
                    logger.info("Stale element found retrying:" + attempts);
                    waitForElementToBeClickableBy(by).click();
                    break;
                } catch (StaleElementReferenceException e1) {
                    logger.info("Stale element found retrying:" + attempts);
                }
            }
        }

protected WebElement waitForElementToBeClickableBy(By by) {
        WebDriverWait wait = new WebDriverWait(getDriver(), 10);
        return wait.until(ExpectedConditions.elementToBeClickable(by));
    }

In above code I first try to wait and then click on element if exception occurs then I catch it and try to loop it as there is a possibility that still all elements may not be loaded and again exception can occur.

Do this:

if (denominator == 0) throw new ArithmeticException("denominator == 0");

ArithmeticException is the exception which is normally thrown when you divide by 0.

Use the Database menu and "Set Datasource Location" menu option to change the name or location of each table in a report.

This works for changing the location of a database, changing to a new database, and changing the location or name of an individual table being used in your report.

To change the datasource connection, go the Database menu and click Set Datasource Location.

1. Change the Datasource Connection:
   1. From the Current Data Source list (the top box), click once on the datasource connection that you want to change.
   2. In the Replace with list (the bottom box), click once on the new datasource connection.
   3. Click Update.
2. Change Individual Tables:
   4. From the Current Data Source list (the top box), expand the datasource connection that you want to change.
   5. Find the table for which you want to update the location or name.
   6. In the Replace with list (the bottom box), expand the new datasource connection.
   7. Find the new table you want to update to point to.
   8. Click Update.
   9. Note that if the table name has changed, the old table name will still appear in the Field Explorer even though it is now using the new table. (You can confirm this be looking at the Table Name of the table's properties in Current Data Source in Set Datasource Location. Screenshot http://i.imgur.com/gzGYVTZ.png) It's possible to rename the old table name to the new name from the context menu in Database Expert -> Selected Tables.
3. Change Subreports:
   9. Repeat each of the above steps for any subreports you might have embedded in your report.
   10. Close the Set Datasource Location window.
4. Any Commands or SQL Expressions:
   11. Go to the Database menu and click Database Expert.
   12. If the report designer used "Add Command" to write custom SQL it will be shown in the Selected Tables box on the right.
   13. Right click that command and choose "Edit Command".
   14. Check if that SQL is specifying a specific database. If so you might need to change it.
   15. Close the Database Expert window.
   16. In the Field Explorer pane on the right, right click any SQL Expressions.
   17. Check if the SQL Expressions are specifying a specific database. If so you might need to change it also.
   18. Save and close your Formula Editor window when you're done editing.

And try running the report again.

The key is to change the datasource connection first, then any tables you need to update, then the other stuff. The connection won't automatically change the tables underneath. Those tables are like goslings that've imprinted on the first large goose-like animal they see. They'll continue to bypass all reason and logic and go to where they've always gone unless you specifically manually change them.

To make it more convenient, here's a tip: You can "Show SQL Query" in the Database menu, and you'll see table names qualified with the database (like "Sales"."dbo"."Customers") for any tables that go straight to a specific database. That might make the hunting easier if you have a lot of stuff going on. When I tackled this problem I had to change each and every table to point to the new table in the new database.

You are trying to call a javascript function. If you want to call a PHP function, you have to use for example a form:

    <form action="action_page.php">
       First name:<br>
       <input type="text" name="firstname" value="Mickey">
       <br>
       Last name:<br>
       <input type="text" name="lastname" value="Mouse">
       <br><br>
       <input type="submit" value="Submit">
     </form> 

(Original Code from: http://www.w3schools.com/html/html_forms.asp)

So if you want do do a asynchron call, you could use 'Ajax' - and yeah, that's the Javascript-Way. But I think, that my code example is enough for this time :)

If it's just a vector of integers, I'd first try:

memset(&my_vector[0], 0, my_vector.size() * sizeof my_vector[0]);

It's not very C++, so I'm sure someone will provide the proper way of doing this. :)

iframe doesn't have onclick event but we can implement this by using iframe's onload event and javascript like this...

function iframeclick() {
document.getElementById("theiframe").contentWindow.document.body.onclick = function() {
        document.getElementById("theiframe").contentWindow.location.reload();
    }
}


<iframe id="theiframe" src="youriframe.html" style="width: 100px; height: 100px;" onload="iframeclick()"></iframe>

I hope it will helpful to you....

For reference I want to add about ExtJS, as explained in Manual: RESTful Web Services. In short, use method to specify GET, POST, PUT, DELETE. Example:

Ext.Ajax.request({
    url: '/articles/restful-web-services',
    method: 'PUT',
    params: {
        author: 'Patrick Donelan',
        subject: 'RESTful Web Services are easy with Ext!'
    }
});

If the Accept header is necessary, it can be set as a default for all requests:

Ext.Ajax.defaultHeaders = {
    'Accept': 'application/json'
};

It's because your enum is not the standard library enum module. You probably have the package enum34 installed.

One way check if this is the case is to inspect the property enum.__file__

import enum
print(enum.__file__)  
# standard library location should be something like 
# /usr/local/lib/python3.6/enum.py

Since python 3.6 the enum34 library is no longer compatible with the standard library. The library is also unnecessary, so you can simply uninstall it.

pip uninstall -y enum34

If you need the code to run on python versions both <=3.4 and >3.4, you can try having enum-compat as a requirement. It only installs enum34 for older versions of python without the standard library enum.

Yeah ./ means the directory you're currently in.

It seems to me that eclipse doesn't recognize the java ee web api (servlets, el, and so on). If you're using maven and don't want to configure eclipse with a specified server runtime, put the dependecy below in your web project pom:

    <groupId>javax</groupId>    
    <artifactId>javaee-web-api</artifactId>    
    <version>7.0</version> <!-- Put here the version of your Java EE app, in my case 7.0 -->
    <scope>provided</scope>

If you want to check by a block, you could try any? or all?.

My inspiration came from "evaluate if array has any items in ruby"

Centos 7 with PHP7.2:

sudo yum --enablerepo=remi-php72 install php-pecl-zip

You could explicitly set where you want to tick marks with plt.xticks:

plt.xticks(np.arange(min(x), max(x)+1, 1.0))

For example,

import numpy as np
import matplotlib.pyplot as plt

x = [0,5,9,10,15]
y = [0,1,2,3,4]
plt.plot(x,y)
plt.xticks(np.arange(min(x), max(x)+1, 1.0))
plt.show()

(np.arange was used rather than Python's range function just in case min(x) and max(x) are floats instead of ints.)

The plt.plot (or ax.plot) function will automatically set default x and y limits. If you wish to keep those limits, and just change the stepsize of the tick marks, then you could use ax.get_xlim() to discover what limits Matplotlib has already set.

start, end = ax.get_xlim()
ax.xaxis.set_ticks(np.arange(start, end, stepsize))

The default tick formatter should do a decent job rounding the tick values to a sensible number of significant digits. However, if you wish to have more control over the format, you can define your own formatter. For example,

ax.xaxis.set_major_formatter(ticker.FormatStrFormatter('%0.1f'))

Here's a runnable example:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.ticker as ticker

x = [0,5,9,10,15]
y = [0,1,2,3,4]
fig, ax = plt.subplots()
ax.plot(x,y)
start, end = ax.get_xlim()
ax.xaxis.set_ticks(np.arange(start, end, 0.712123))
ax.xaxis.set_major_formatter(ticker.FormatStrFormatter('%0.1f'))
plt.show()

@bdiamante's answer may only partially help you. If you still get a message after you've suppressed warnings, it's because the pandas library itself is printing the message. There's not much you can do about it unless you edit the Pandas source code yourself. Maybe there's an option internally to suppress them, or a way to override things, but I couldn't find one.

For those who need to know why...

Suppose that you want to ensure a clean working environment. At the top of your script, you put pd.reset_option('all'). With Pandas 0.23.4, you get the following:

>>> import pandas as pd
>>> pd.reset_option('all')
html.border has been deprecated, use display.html.border instead
(currently both are identical)

C:\projects\stackoverflow\venv\lib\site-packages\pandas\core\config.py:619: FutureWarning: html.bord
er has been deprecated, use display.html.border instead
(currently both are identical)

  warnings.warn(d.msg, FutureWarning)

: boolean
    use_inf_as_null had been deprecated and will be removed in a future
    version. Use `use_inf_as_na` instead.

C:\projects\stackoverflow\venv\lib\site-packages\pandas\core\config.py:619: FutureWarning:
: boolean
    use_inf_as_null had been deprecated and will be removed in a future
    version. Use `use_inf_as_na` instead.

  warnings.warn(d.msg, FutureWarning)

>>>

Following the @bdiamante's advice, you use the warnings library. Now, true to it's word, the warnings have been removed. However, several pesky messages remain:

>>> import warnings
>>> warnings.simplefilter(action='ignore', category=FutureWarning)
>>> import pandas as pd
>>> pd.reset_option('all')
html.border has been deprecated, use display.html.border instead
(currently both are identical)


: boolean
    use_inf_as_null had been deprecated and will be removed in a future
    version. Use `use_inf_as_na` instead.

>>>

In fact, disabling all warnings produces the same output:

>>> import warnings
>>> warnings.simplefilter(action='ignore', category=Warning)
>>> import pandas as pd
>>> pd.reset_option('all')
html.border has been deprecated, use display.html.border instead
(currently both are identical)


: boolean
    use_inf_as_null had been deprecated and will be removed in a future
    version. Use `use_inf_as_na` instead.

>>>

In the standard library sense, these aren't true warnings. Pandas implements its own warnings system. Running grep -rn on the warning messages shows that the pandas warning system is implemented in core/config_init.py:

$ grep -rn "html.border has been deprecated"
core/config_init.py:207:html.border has been deprecated, use display.html.border instead

Further chasing shows that I don't have time for this. And you probably don't either. Hopefully this saves you from falling down the rabbit hole or perhaps inspires someone to figure out how to truly suppress these messages!

Microsoft Visual Studio is funny when your using the installer you MUST checkbox a-lot of options to bypass the .netframework(somewhat) to make more c++ instead of c sharp applications, such as the clr options under dekstop development... in visual studio installer.... difference is c++ win32 console project or a c++ CLR console project. So whats the difference? Well i'm not going to list all of the files CLR includes but since most good c++ kernals are in linux... so CLR allows you to bypass a-lot of the windows .netframework b/c visual studio was really meant for you to make apps in C sharp.

Heres a C++ win32 console project!

#include "stdafx.h"
#include <iostream>
using namespace std;
int main( )
{
cout<<"Hello World"<<endl;
return 0;
}

Now heres a c++ CLR console project!

#include "stdafx.h"

using namespace System;

int main(array<System::String ^> ^args)
{
Console::WriteLine("Hello World");
return 0;
}

Both programs do the same thing .... CLR just looks more frameworked class overloading methodology so microsoft can great it's own vast library you should familiarize yourself w/ if so inclined. https://msdn.microsoft.com/en-us/library/2e6a4at9.aspx

In Django 1.7 JsonResponse objects have been added to the Django framework itself which makes this task even easier:

from django.http import JsonResponse
def some_view(request):
    return JsonResponse({"key": "value"})

<activity
    ...
    android:windowSoftInputMode="stateVisible" >
</activity>

or

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);

you can also use $sce.trustAsHtml('"<h1>" + str + "</h1>"'),if you want to know more detail, please refer to $sce

SQlite does not have a specific datetime type. You can use TEXT, REAL or INTEGER types, whichever suits your needs.

Straight from the DOCS

SQLite does not have a storage class set aside for storing dates and/or times. Instead, the built-in Date And Time Functions of SQLite are capable of storing dates and times as TEXT, REAL, or INTEGER values:

• TEXT as ISO8601 strings ("YYYY-MM-DD HH:MM:SS.SSS").
• REAL as Julian day numbers, the number of days since noon in Greenwich on November 24, 4714 B.C. according to the proleptic Gregorian calendar.
• INTEGER as Unix Time, the number of seconds since 1970-01-01 00:00:00 UTC.

Applications can chose to store dates and times in any of these formats and freely convert between formats using the built-in date and time functions.

SQLite built-in Date and Time functions can be found here.

It is better to use the functionality provided by Eclipse which does a pretty good job and you can put your efforts and energy in developing the business logic.

Try this:

Open PgAdmin -> Files -> Open pgpass.conf

You would get the path of pgpass.conf at the bottom of the window. Go to that location and open this file, you can find your password there.

Reference

If the above does not work, you may consider trying this:

 1. edit pg_hba.conf to allow trust authorization temporarily
 2. Reload the config file (pg_ctl reload)
 3. Connect and issue ALTER ROLE / PASSWORD to set the new password
 4. edit pg_hba.conf again and restore the previous settings
 5. Reload the config file again

Citing the official javadoc of List.addAll:

Appends all of the elements in the specified collection to the end of
this list, in the order that they are returned by the specified
collection's iterator (optional operation).  The behavior of this
operation is undefined if the specified collection is modified while
the operation is in progress.  (Note that this will occur if the
specified collection is this list, and it's nonempty.)

So you will copy the references of the objects in list to anotherList. Any method that does not operate on the referenced objects of anotherList (such as removal, addition, sorting) is local to it, and therefore will not influence list.

The thing is that you are using the option -t when running your container.

Could you check if enabling the tty option (see reference) in your docker-compose.yml file the container keeps running?

version: '2'
services:
  ubuntu:
        build: .
        container_name: ubuntu
        volumes:
            - ~/sph/laravel52:/www/laravel
        ports:
          - "80:80"
        tty: true

Put the "hibernate-entitymanager.jar" in the classpath of application.
For newer versions, you should use "hibernate-core.jar" instead of the deprecated hibernate-entitymanager

If you are running through some IDE, like Eclipse: Project Properties -> Java Build Path -> Libraries.

Otherwise put it in the /lib of your application.

They might be just a \r or a \n. I just checked and the text visualizer in VS 2010 displays both as newlines as well as \r\n.

This string

string test = "blah\r\nblah\rblah\nblah";

Shows up as

blah
blah
blah
blah

in the text visualizer.

So you could try

string modifiedString = originalString
    .Replace(Environment.NewLine, "<br />")
    .Replace("\r", "<br />")
    .Replace("\n", "<br />");

I suspect there is something wrong either with your Git installation or your repository.

Try running:

GIT_TRACE=2 git <command>

See if you get anything useful. If that doesn't help, just use strace and see what's going wrong:

strace git <command>

To add to Heath's answer: It looks like Subversion 1.6 disabled storing passwords by default if it can't store them in encrypted form. You can allow storing unencrypted passwords by explicitly setting password-stores = (that is, to the empty value) in ~/.subversion/config.

To check which password store subversion uses, look in ~/.subversion/auth/svn.simple. This contains several files, each a hash table with a simple key/value encoding. The svn:realmstring in each file identifies which realm that file is for. If the file has

K 8
passtype
V 6
simple

then it stores the password in plain text somewhere in that file, in a K 8 password entry. Else, it tries to use one of the configured password-stores.

You can check your all defined function by

$arr = get_defined_functions();
print_r($arr);

this will give you array of all functions in if your function exist in it you can use it like:

 {{ user.myfunction({{parameter}}) }}

Possibly related, if you want to initialize and fill an array with a range of values, use PHP's (wait for it...) range function:

$a = range(1, 5);  // array(1,2,3,4,5)
$a = range(0, 10, 2); // array(0,2,4,6,8,10)

This project has been tested with Xcode 10 and Swift 4.2.

Create a new project

It can be just a Single View App.

Add the code

Create a new Cocoa Touch Class file (File > New > File... > iOS > Cocoa Touch Class). Name it MyCollectionViewCell. This class will hold the outlets for the views that you add to your cell in the storyboard.

import UIKit
class MyCollectionViewCell: UICollectionViewCell {
    
    @IBOutlet weak var myLabel: UILabel!
}

We will connect this outlet later.

Open ViewController.swift and make sure you have the following content:

import UIKit
class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate {
    
    let reuseIdentifier = "cell" // also enter this string as the cell identifier in the storyboard
    var items = ["1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29", "30", "31", "32", "33", "34", "35", "36", "37", "38", "39", "40", "41", "42", "43", "44", "45", "46", "47", "48"]
    
    
    // MARK: - UICollectionViewDataSource protocol
    
    // tell the collection view how many cells to make
    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return self.items.count
    }
    
    // make a cell for each cell index path
    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        
        // get a reference to our storyboard cell
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath as IndexPath) as! MyCollectionViewCell
        
        // Use the outlet in our custom class to get a reference to the UILabel in the cell
        cell.myLabel.text = self.items[indexPath.row] // The row value is the same as the index of the desired text within the array.
        cell.backgroundColor = UIColor.cyan // make cell more visible in our example project
        
        return cell
    }
    
    // MARK: - UICollectionViewDelegate protocol
    
    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
        // handle tap events
        print("You selected cell #\(indexPath.item)!")
    }
}

Notes

• UICollectionViewDataSource and UICollectionViewDelegate are the protocols that the collection view follows. You could also add the UICollectionViewFlowLayout protocol to change the size of the views programmatically, but it isn't necessary.
• We are just putting simple strings in our grid, but you could certainly do images later.

Set up the storyboard

Drag a Collection View to the View Controller in your storyboard. You can add constraints to make it fill the parent view if you like.

Make sure that your defaults in the Attribute Inspector are also

• Items: 1
• Layout: Flow

The little box in the top left of the Collection View is a Collection View Cell. We will use it as our prototype cell. Drag a Label into the cell and center it. You can resize the cell borders and add constraints to center the Label if you like.

Write "cell" (without quotes) in the Identifier box of the Attributes Inspector for the Collection View Cell. Note that this is the same value as let reuseIdentifier = "cell" in ViewController.swift.

And in the Identity Inspector for the cell, set the class name to MyCollectionViewCell, our custom class that we made.

Hook up the outlets

• Hook the Label in the collection cell to myLabel in the MyCollectionViewCell class. (You can Control-drag.)
• Hook the Collection View delegate and dataSource to the View Controller. (Right click Collection View in the Document Outline. Then click and drag the plus arrow up to the View Controller.)

Finished

Here is what it looks like after adding constraints to center the Label in the cell and pinning the Collection View to the walls of the parent.

Making Improvements

The example above works but it is rather ugly. Here are a few things you can play with:

Background color

In the Interface Builder, go to your Collection View > Attributes Inspector > View > Background.

Cell spacing

Changing the minimum spacing between cells to a smaller value makes it look better. In the Interface Builder, go to your Collection View > Size Inspector > Min Spacing and make the values smaller. "For cells" is the horizontal distance and "For lines" is the vertical distance.

Cell shape

If you want rounded corners, a border, and the like, you can play around with the cell layer. Here is some sample code. You would put it directly after cell.backgroundColor = UIColor.cyan in code above.

cell.layer.borderColor = UIColor.black.cgColor
cell.layer.borderWidth = 1
cell.layer.cornerRadius = 8

See this answer for other things you can do with the layer (shadow, for example).

Changing the color when tapped

It makes for a better user experience when the cells respond visually to taps. One way to achieve this is to change the background color while the cell is being touched. To do that, add the following two methods to your ViewController class:

// change background color when user touches cell
func collectionView(_ collectionView: UICollectionView, didHighlightItemAt indexPath: IndexPath) {
    let cell = collectionView.cellForItem(at: indexPath)
    cell?.backgroundColor = UIColor.red
}

// change background color back when user releases touch
func collectionView(_ collectionView: UICollectionView, didUnhighlightItemAt indexPath: IndexPath) {
    let cell = collectionView.cellForItem(at: indexPath)
    cell?.backgroundColor = UIColor.cyan
}

Here is the updated look:

UITableView version of this Q&A

• UITableView example for Swift

For a seaborn.heatmap, you can rotate these using (based on @Aman's answer)

pandas_frame = pd.DataFrame(data, index=names, columns=names)
heatmap = seaborn.heatmap(pandas_frame)
loc, labels = plt.xticks()
heatmap.set_xticklabels(labels, rotation=45)
heatmap.set_yticklabels(labels[::-1], rotation=45) # reversed order for y

For anyone stumbling upon this thread, here's a more complete solution. It will compare two objects and give you the key of all properties that are either only in object1, only in object2, or are both in object1 and object2 but have different values:

/*
 * Compare two objects by reducing an array of keys in obj1, having the
 * keys in obj2 as the intial value of the result. Key points:
 *
 * - All keys of obj2 are initially in the result.
 *
 * - If the loop finds a key (from obj1, remember) not in obj2, it adds
 *   it to the result.
 *
 * - If the loop finds a key that are both in obj1 and obj2, it compares
 *   the value. If it's the same value, the key is removed from the result.
 */
function getObjectDiff(obj1, obj2) {
    const diff = Object.keys(obj1).reduce((result, key) => {
        if (!obj2.hasOwnProperty(key)) {
            result.push(key);
        } else if (_.isEqual(obj1[key], obj2[key])) {
            const resultKeyIndex = result.indexOf(key);
            result.splice(resultKeyIndex, 1);
        }
        return result;
    }, Object.keys(obj2));

    return diff;
}

Here's an example output:

// Test
let obj1 = {
    a: 1,
    b: 2,
    c: { foo: 1, bar: 2},
    d: { baz: 1, bat: 2 }
}

let obj2 = {
    b: 2, 
    c: { foo: 1, bar: 'monkey'}, 
    d: { baz: 1, bat: 2 }
    e: 1
}
getObjectDiff(obj1, obj2)
// ["c", "e", "a"]

If you don't care about nested objects and want to skip lodash, you can substitute the _.isEqual for a normal value comparison, e.g. obj1[key] === obj2[key].

Use ROW_NUMBER(if you want a single) or DENSE_RANK(for all related rows):

WITH CTE AS
(
    SELECT EmpID, EmpName, EmpSalary,
           RN = ROW_NUMBER() OVER (ORDER BY EmpSalary DESC)
    FROM dbo.Salary
)
SELECT EmpID, EmpName, EmpSalary
FROM CTE
WHERE RN = @NthRow

I noticed some of the answers were not triggering the HTML5 required attribute (as stuff was being executed on the action of clicking rather than the action of form send, causing to bypass it when the inputs were empty):

1. Have a <form id='xform'></form> with some inputs with the required attribute and place a <input type='submit'> at the end.
2. A confirmation input where typing "ok" is expected <input type='text' name='xconf' value='' required>
3. Add a modal_1_confirm to your html (to confirm the form of sending).
4. (on modal_1_confirm) add the id modal_1_accept to the accept button.
5. Add a second modal_2_errMsg to your html (to display form validation errors).
6. (on modal_2_errMsg) add the id modal_2_accept to the accept button.
7. (on modal_2_errMsg) add the id m2_Txt to the displayed text holder.

8. The JS to intercept before the form is sent:

   $("#xform").submit(function(e){
       var msg, conf, preventSend;
   
       if($("#xform").attr("data-send")!=="ready"){
           msg="Error."; //default error msg
           preventSend=false;
   
           conf=$("[name='xconf']").val().toLowerCase().replace(/^"|"$/g, "");
   
           if(conf===""){
               msg="The field is empty.";
               preventSend=true;
           }else if(conf!=="ok"){
               msg="You didn't write \"ok\" correctly.";
               preventSend=true;
           }
   
           if(preventSend){ //validation failed, show the error
               $("#m2_Txt").html(msg); //displayed text on modal_2_errMsg
               $("#modal_2_errMsg").modal("show");
           }else{ //validation passed, now let's confirm the action
               $("#modal_1_confirm").modal("show");
           }
   
           e.preventDefault();
           return false;
       }
   });
   

`9. Also some stuff when clicking the Buttons from the modals:

$("#modal_1_accept").click(function(){
    $("#modal_1_confirm").modal("hide");
    $("#xform").attr("data-send", "ready").submit();
});

$("#modal_2_accept").click(function(){
    $("#modal_2_errMsg").modal("hide");
});

Important Note: So just be careful if you add an extra way to show the modal, as simply clicking the accept button $("#modal_1_accept") will assume the validation passed and it will add the "ready" attribute:

• The reasoning for this is that $("#modal_1_confirm").modal("show"); is shown only when it passed the validation, so clicking $("#modal_1_accept") should be unreachable without first getting the form validated.

You can define style rules which only apply to specific elements inside your div with id divContainer like this:

#divContainer input { ... }
#divContainer input[type="radio"] { ... }
#divContainer input[type="text"] { ... }
/* etc */

This worked for me in case you want to change the AUTO_INCREMENT-attribute for a not-empty-table:

1.)Exported the whole table as .sql file
2.)Deleted the table after export
2.)Did needed change in CREATE_TABLE command
3.)Executed the CREATE_TABLE and INSERT_INTO commands from the .sql-file
...et viola

Please use the below code and let me know

try{

            Class.forName("com.mysql.jdbc.Driver").newInstance();
            con = DriverManager.getConnection(c, "root", "MyNewPass");
            System.out.println("connection done");


            PreparedStatement ps=con.prepareStatement(q);
            System.out.println(q);
            rs=ps.executeQuery();
            System.out.println("done2");
            while (rs.next()) {
               System.out.println(rs.getString(1));
               System.out.println(rs.getString(2));

            }

         response.sendRedirect("myfolder/welcome.jsp"); // wherever you wanna redirect this page.

        }
            catch (Exception e) {
                // TODO: handle exception
                System.out.println("Failed");
            }

myfolder/welcome.jsp is the relative path of your jsp page. So, change it as per your jsp page path.

To clear from the current position to the end of the current line, do this:

    public static void ClearToEndOfCurrentLine()
    {
        int currentLeft = Console.CursorLeft;
        int currentTop = Console.CursorTop;
        Console.Write(new String(' ', Console.WindowWidth - currentLeft));
        Console.SetCursorPosition(currentLeft, currentTop);
    }

You need to be using .val() not .value

$(document).ready(function () {
  if ($("textarea").val() != "") {
    alert($("textarea").val());
  }
});

If you have just started with angular and bootstrap then simple answer would be below steps: 1. Add node package of bootstrap as dev dependency

npm install --save bootstrap

2. import bootstrap stylessheet in angular.json file.

   "styles": [ "projects/my-app/src/styles.scss", "./node_modules/bootstrap/dist/css/bootstrap.min.css" ],

3. and you are ready to use bootstrap for styling, grid etc.

   <div class="container">My first bootstrap div</div>

The best part of this which I found was that we are directing using bootstrap without any third-party module dependency. We can upgrade bootstrap anytime by just updating the command npm install --save [email protected] etc.

I had the same problem.

In my case the problem was with maven home directory and user settings file in Intellij Settings under Maven. I had installed Maven not in the default directory and I had also changed the location of the settings.xml file. This should also be changed in the IntelliJ Settings.

Hope this helps also.

If any of the answers mentioned here doesn't work then go to File > Invalidate Catches/Restart

You can omit window and just use location.href. For example:

location.href = 'http://google.im/';

You can do it using the fs-extra module very easily:

const fse = require('fs-extra');

let srcDir = 'path/to/file';
let destDir = 'pat/to/destination/directory';

fse.moveSync(srcDir, destDir, function (err) {

    // To move a file permanently from a directory
    if (err) {
        console.error(err);
    } else {
        console.log("success!");
    }
});

Or

fse.copySync(srcDir, destDir, function (err) {

     // To copy a file from a directory
     if (err) {
         console.error(err);
     } else {
         console.log("success!");
     }
});

Getting a standalone month name is surprisingly difficult to perform "right" in Java. (At least as of this writing. I'm currently using Java 8).

The problem is that in some languages, including Russian and Czech, the standalone version of the month name is different from the "formatting" version. Also, it appears that no single Java API will just give you the "best" string. The majority of answers posted here so far only offer the formatting version. Pasted below is a working solution for getting the standalone version of a single month name, or getting an array with all of them.

I hope this saves someone else some time!

/**
 * getStandaloneMonthName, This returns a standalone month name for the specified month, in the
 * specified locale. In some languages, including Russian and Czech, the standalone version of
 * the month name is different from the version of the month name you would use as part of a
 * full date. (Different from the formatting version).
 *
 * This tries to get the standalone version first. If no mapping is found for a standalone
 * version (Presumably because the supplied language has no standalone version), then this will
 * return the formatting version of the month name.
 */
private static String getStandaloneMonthName(Month month, Locale locale, boolean capitalize) {
    // Attempt to get the standalone version of the month name.
    String monthName = month.getDisplayName(TextStyle.FULL_STANDALONE, locale);
    String monthNumber = "" + month.getValue();
    // If no mapping was found, then get the formatting version of the month name.
    if (monthName.equals(monthNumber)) {
        DateFormatSymbols dateSymbols = DateFormatSymbols.getInstance(locale);
        monthName = dateSymbols.getMonths()[month.getValue()];
    }
    // If needed, capitalize the month name.
    if ((capitalize) && (monthName != null) && (monthName.length() > 0)) {
        monthName = monthName.substring(0, 1).toUpperCase(locale) + monthName.substring(1);
    }
    return monthName;
}

/**
 * getStandaloneMonthNames, This returns an array with the standalone version of the full month
 * names.
 */
private static String[] getStandaloneMonthNames(Locale locale, boolean capitalize) {
    Month[] monthEnums = Month.values();
    ArrayList<String> monthNamesArrayList = new ArrayList<>();
    for (Month monthEnum : monthEnums) {
        monthNamesArrayList.add(getStandaloneMonthName(monthEnum, locale, capitalize));
    }
    // Convert the arraylist to a string array, and return the array.
    String[] monthNames = monthNamesArrayList.toArray(new String[]{});
    return monthNames;
}

Here is simple steps add this gradle:

dependencies {
  compile "com.google.firebase:firebase-messaging:9.0.0"
}

No extra permission are needed in manifest like GCM. No receiver is needed to manifest like GCM. With FCM, com.google.android.gms.gcm.GcmReceiver is added automatically.

Migrate your listener service

A service extending InstanceIDListenerService is now required only if you want to access the FCM token.

This is needed if you want to

• Manage device tokens to send a messages to single device directly, or Send messages to device group, or
• Send messages to device group, or
• Subscribe devices to topics with the server subscription management API.

Add Service in manifest

<service
    android:name=".MyInstanceIDListenerService">
    <intent-filter>
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
    </intent-filter>
</service>

<service
    android:name=".MyFirebaseInstanceIDService">
    <intent-filter>
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
    </intent-filter>
</service>

Change MyInstanceIDListenerService to extend FirebaseInstanceIdService, and update code to listen for token updates and get the token whenever a new token is generated.

public class MyInstanceIDListenerService extends FirebaseInstanceIdService {

  ...

  /**
   * Called if InstanceID token is updated. This may occur if the security of
   * the previous token had been compromised. Note that this is also called
   * when the InstanceID token is initially generated, so this is where
   * you retrieve the token.
   */
  // [START refresh_token]
  @Override
  public void onTokenRefresh() {
      // Get updated InstanceID token.
      String refreshedToken = FirebaseInstanceId.getInstance().getToken();
      Log.d(TAG, "Refreshed token: " + refreshedToken);
      // TODO: Implement this method to send any registration to your app's servers.
      sendRegistrationToServer(refreshedToken);
  }

When filtering a DataFrame with string values, I find that the pyspark.sql.functions lower and upper come in handy, if your data could have column entries like "foo" and "Foo":

import pyspark.sql.functions as sql_fun
result = source_df.filter(sql_fun.lower(source_df.col_name).contains("foo"))

I use @gnarf's method, though I fall back on document.writelning a <script> tag for IE<7 as I couldn't get DOM creation to work reliably in IE6 (and TBH didn't care enough to put much effort into it). The core of my code is:

if (horus.script.broken) {
    document.writeln('<script type="text/javascript" src="'+script+'"></script>');   
    horus.script.loaded(script);
} else {
    var s=document.createElement('script');
    s.type='text/javascript';
    s.src=script;
    s.async=true;

    if (horus.brokenDOM){
        s.onreadystatechange=
            function () {
                if (this.readyState=='loaded' || this.readyState=='complete'){
                    horus.script.loaded(script);
                }
        }
    }else{
        s.onload=function () { horus.script.loaded(script) };
    }

    document.head.appendChild(s);
}

where horus.script.loaded() notes that the javascript file is loaded, and calls any pending uncalled routines (saved by autoloader code).

You can use strstr. Example code here.

Note that the returned result is not null terminated.

It's a way to enforce a set of invariants of the abstract class. That is, no matter what the subclass does, you want to make sure some things are always true of the base class... example:

abstract class Foo
{
    public DateTime TimeCreated {get; private set;}

    protected Foo()
    {
         this.TimeCreated = DateTime.Now;
    }
}

abstract class Bar : Foo
{
    public Bar() : base() //Bar's constructor's must call Foo's parameterless constructor.
    { }
}

Don't think of a constructor as the dual of the new operator. The constructor's only purpose is to ensure that you have an object in a valid state before you start using it. It just happens to be that we usually call it through a new operator.

The NEW values (or NEW_BUFFER as you have renamed them) are only available when INSERTING and UPDATING. For DELETING you would need to use OLD (OLD_BUFFER). So your trigger would become:

CREATE or REPLACE TRIGGER test001
  AFTER INSERT OR DELETE OR UPDATE ON tabletest001
  REFERENCING OLD AS old_buffer NEW AS new_buffer 
  FOR EACH ROW WHEN (new_buffer.field1 = 'HBP00' OR old_buffer.field1 = 'HBP00') 

You may need to add logic inside the trigger to cater for code that updates field1 from 'HBP000' to something else.

You must declare int add(int a, int b); (note to the semicolon) in a header file and include the file into both files. Including it into Main.c will tell compiler how the function should be called. Including into the second file will allow you to check that declaration is valid (compiler would complain if declaration and implementation were not matched).

Then you must compile both *.c files into one project. Details are compiler-dependent.

AFAIK there is no possibility beside from using keys or expect if you are using the command line version ssh. But there are library bindings for the most programming languages like C, python, php, ... . You could write a program in such a language. This way it would be possible to pass the password automatically. But note this is of course a security problem as the password will be stored in plain text in that program

One thing that caused me a massive headache when using this code (might affect others and I wish that somebody had left a comment like this one here for me to read):

• My aim is to create a dynamic access dashboard, which requires that its linked tables be updated.
• I use the copy methods described above to replace the existing linked CSVs with an updated version of them.
• Running the above code manually from a module worked fine.
• Running identical code from a form linked to the CSV data had runtime error 70 (Permission denied), even tho the first step of my code was to close that form (which should have unlocked the CSV file so that it could be overwritten).
• I now believe that despite the form being closed, it keeps the outdated CSV file locked while it executes VBA associated with that form.

My solution will be to run the code (On timer event) from another hidden form that opens with the database.

The modern approach: flexbox

Simply add the following CSS to the container element (here, the div):

div {
  display: flex;
  justify-content: space-between;
}

div {_x000D_
  display: flex;_x000D_
  justify-content: space-between;_x000D_
}

<div>_x000D_
 <img src="http://placehold.it/100x100" alt=""  /> _x000D_
 <img src="http://placehold.it/100x100" alt=""  />_x000D_
 <img src="http://placehold.it/100x100" alt="" />_x000D_
</div>

The old way (for ancient browsers - prior to flexbox)

Use text-align: justify; on the container element.

Then stretch the content to take up 100% width

MARKUP

<div>
 <img src="http://placehold.it/100x100" alt=""  /> 
 <img src="http://placehold.it/100x100" alt=""  />
 <img src="http://placehold.it/100x100" alt="" />
</div>

CSS

div {
    text-align: justify;
}

div img {
    display: inline-block;
    width: 100px;
    height: 100px;
}

div:after {
    content: '';
    display: inline-block;
    width: 100%;
}

div {_x000D_
    text-align: justify;_x000D_
}_x000D_
_x000D_
div img {_x000D_
    display: inline-block;_x000D_
    width: 100px;_x000D_
    height: 100px;_x000D_
}_x000D_
_x000D_
div:after {_x000D_
    content: '';_x000D_
    display: inline-block;_x000D_
    width: 100%;_x000D_
}

<div>_x000D_
 <img src="http://placehold.it/100x100" alt=""  /> _x000D_
 <img src="http://placehold.it/100x100" alt=""  />_x000D_
 <img src="http://placehold.it/100x100" alt="" />_x000D_
</div>

I am a little late to the party but I thought I'd share a way of doing it, if you have identical types of conditions, i.e. checking if all, any or at given amount of A_1=A_2 and B_1=B_2, this can be done in the following way:

cond_list_1=["1","2","3"]
cond_list_2=["3","2","1"]
nr_conds=1

if len([True for i, j in zip(cond_list_1, cond_list_2) if i == j])>=nr_conds:
    print("At least " + str(nr_conds) + " conditions are fullfilled")

if len([True for i, j in zip(cond_list_1, cond_list_2) if i == j])==len(cond_list_1):
    print("All conditions are fullfilled")

This means you can just change in the two initial lists, at least for me this makes it easier.

The WSDL is a kind of contract between API provider and the client it's describe the web service : the public function , optional/required field ...

But The soap message is a data transferred between client and provider (payload)

To get back to the parent frame, use:

driver.switchTo().parentFrame();

To get back to the first/main frame, use:

driver.switchTo().defaultContent();

You can use pathlib.

For Python 3.5 and above:

from pathlib import Path
contents = Path(file_path).read_text()

For older versions of Python use pathlib2:

$ pip install pathlib2

Then:

from pathlib2 import Path
contents = Path(file_path).read_text()

This is the actual read_text implementation:

def read_text(self, encoding=None, errors=None):
    """
    Open the file in text mode, read it, and close the file.
    """
    with self.open(mode='r', encoding=encoding, errors=errors) as f:
        return f.read()

I recommand you using PowerShell

Set Android Studio Terminal to PowerShell:

Settings > Tools > Terminal > Shell path = pwsh.exe (instead of cmd.exe)

Open Terminal on Android Studio

PowerShell 7.0.1
Copyright (c) Microsoft Corporation. All rights reserved.

https://aka.ms/powershell
Type 'help' to get help.

PS >

Test the path for adb.exe

# `pikachu` should be replace your username
PS > test-path "C:\Users\pikachu\AppData\Local\Android\sdk\platform-tools"
True

Open your powershell profile file in your text editor

PS > notepad $profile

add below line, save and exit

# `pikachu` should be replaced with your username
$env:PATH+="C:\Users\pikachu\AppData\Local\Android\sdk\platform-tools"

re-open Terminal and try adb

PS > adb
Android Debug Bridge version 1.0.41

 -t ID      use device with given transport id
 -H         name of adb server host [default=localhost]
 -P         port of adb server [default=5037]

Just to add to the above answer, anyone finding an issue of the installers taking forever, I found my issue was python, I uninstalled both my versions 3 and versions 2.

The re-ran the command in PowerShell terminal as the admin and it installed almost straight away.

npm install --global --production windows-build-tools 

There is another trick :

/* Padding on the sides of the table */
table th:first-child, .list td:first-child { padding-left: 28px; }
table th:last-child, .list td:last-child { padding-right: 28px; }

(Just saw it at my current job)

1. Open the windows command line (type "cmd" on the search box and hit enter).
2. It'll default to your home folder, so you don't need to cd to a different one.
3. Type mkdir .ssh

if you're dealing with the iOS5 upgrade, I found that for compiling a project written to target 4.3, I could just rename libz.1.2.3.dynlib in the Project Navigator to libz.1.2.5.dynlib and it compiled.

My iPhoneOS50SDK/usr/lib folder has no libz.1.2.3.dynlib--don't know whether it's a beta thing or just natural upgrade.

Open .dll file with visual studio. Or resource editor.

Since vertical-align works as expected on a td, you could put a single celled table in the div to align its content.

<div>
    <table style="width: 100%; height: 100%;"><tr><td style="vertical-align: middle; text-align: center">
        Aligned content here...
    </td></tr></table>
</div>

Clunky, but works as far as I can tell. It might not have the drawbacks of the other workarounds.

The code is like this:

In Aspx:

<asp:Button ID="btnSave" runat="server" Text="Save" OnClick="btnSave_Click" CausesValidation=true />

in Cs:

protected void Page_Load(object sender, System.EventArgs e)
{
     if (!IsPostBack)
     {
         btnSave.Attributes["Onclick"] = "return confirm('Do you really want to save?')";          
     }
}

protected void btnSave_Click(object sender, EventArgs e){
    Page.Validate();
    if (Page.IsValid)
    {
       //Update the database
         lblMessage.Text = "Saved Successfully";
    }
}

If you only need the first row from each group we can do with drop_duplicates, Notice the function default method keep='first'.

df.drop_duplicates('id')
Out[1027]: 
    id   value
0    1   first
3    2   first
5    3   first
9    4  second
11   5   first
12   6   first
15   7  fourth

I think it's the button "active" state.

Laravel Mix 4 switches from node-sass to dart-sass (which may not compile as you would expect, OR you have to deal with the issues one by one)

OR

npm install node-sass


mix.sass('resources/sass/app.sass', 'public/css', {
implementation: require('node-sass')
});

You can use the operator to sort the dictionary by values in descending order.

import operator

d = {"a":1, "b":2, "c":3}
cd = sorted(d.items(),key=operator.itemgetter(1),reverse=True)

The Sorted dictionary will look like,

cd = {"c":3, "b":2, "a":1}

Here, operator.itemgetter(1) takes the value of the key which is at the index 1.

My English is not good so I'll just write a simple example here.

    double a = 0.02;
    double b = 0.03;
    double c = b - a;
    System.out.println(c);

    BigDecimal _a = new BigDecimal("0.02");
    BigDecimal _b = new BigDecimal("0.03");
    BigDecimal _c = _b.subtract(_a);
    System.out.println(_c);

Program output:

0.009999999999999998
0.01

Somebody still want to use double? ;)

To account for leading and trailing whitespace, you probably want to use normalize-space()

//div[contains(@class, 'Caption') and normalize-space(.)='Model saved']

and

//div[@id='alertLabel' and normalize-space(.)='Save to server successful']

Note that //div[contains(@class, 'Caption') and normalize-space(.//text())='Model saved'] also works.

You should try using quotes.

cmd /C "C:\Program Files (x86)\WinRar\Rar.exe" a "D:\Hello 2\File.rar" "D:\Hello 2\*.*"

In this code you are not comparing string values, you are comparing pointer values. If you want to compare string values you need to use a string comparison function such as strcmp.

if ( 0 == strcmp(var1, "dev")) {
  ..
}

You should use Directory.CreateDirectory.

It looks like you are executing that command from a DOS session (see this thread), and that means you need to create the .ssh directory before said command.

Or you can execute it from the bash session (part of the msysgit distribution), and it should work.

I originally posted the benchmarks below with the purpose of recommending numpy.corrcoef, foolishly not realizing that the original question already uses corrcoef and was in fact asking about higher order polynomial fits. I've added an actual solution to the polynomial r-squared question using statsmodels, and I've left the original benchmarks, which while off-topic, are potentially useful to someone.

statsmodels has the capability to calculate the r^2 of a polynomial fit directly, here are 2 methods...

import statsmodels.api as sm
import statsmodels.formula.api as smf

# Construct the columns for the different powers of x
def get_r2_statsmodels(x, y, k=1):
    xpoly = np.column_stack([x**i for i in range(k+1)])    
    return sm.OLS(y, xpoly).fit().rsquared

# Use the formula API and construct a formula describing the polynomial
def get_r2_statsmodels_formula(x, y, k=1):
    formula = 'y ~ 1 + ' + ' + '.join('I(x**{})'.format(i) for i in range(1, k+1))
    data = {'x': x, 'y': y}
    return smf.ols(formula, data).fit().rsquared # or rsquared_adj

To further take advantage of statsmodels, one should also look at the fitted model summary, which can be printed or displayed as a rich HTML table in Jupyter/IPython notebook. The results object provides access to many useful statistical metrics in addition to rsquared.

model = sm.OLS(y, xpoly)
results = model.fit()
results.summary()

Below is my original Answer where I benchmarked various linear regression r^2 methods...

The corrcoef function used in the Question calculates the correlation coefficient, r, only for a single linear regression, so it doesn't address the question of r^2 for higher order polynomial fits. However, for what it's worth, I've come to find that for linear regression, it is indeed the fastest and most direct method of calculating r.

def get_r2_numpy_corrcoef(x, y):
    return np.corrcoef(x, y)[0, 1]**2

These were my timeit results from comparing a bunch of methods for 1000 random (x, y) points:

• Pure Python (direct r calculation)
  • 1000 loops, best of 3: 1.59 ms per loop
• Numpy polyfit (applicable to n-th degree polynomial fits)
  • 1000 loops, best of 3: 326 µs per loop
• Numpy Manual (direct r calculation)
  • 10000 loops, best of 3: 62.1 µs per loop
• Numpy corrcoef (direct r calculation)
  • 10000 loops, best of 3: 56.6 µs per loop
• Scipy (linear regression with r as an output)
  • 1000 loops, best of 3: 676 µs per loop
• Statsmodels (can do n-th degree polynomial and many other fits)
  • 1000 loops, best of 3: 422 µs per loop

The corrcoef method narrowly beats calculating the r^2 "manually" using numpy methods. It is >5X faster than the polyfit method and ~12X faster than the scipy.linregress. Just to reinforce what numpy is doing for you, it's 28X faster than pure python. I'm not well-versed in things like numba and pypy, so someone else would have to fill those gaps, but I think this is plenty convincing to me that corrcoef is the best tool for calculating r for a simple linear regression.

Here's my benchmarking code. I copy-pasted from a Jupyter Notebook (hard not to call it an IPython Notebook...), so I apologize if anything broke on the way. The %timeit magic command requires IPython.

Failed to start mongod.service: Unit mongod.service not found

If you are following the official doc and are coming across with the error above that means mongod.service is not enabled yet on you machine (I am talking about Ubuntu 16.04). You need to do that using following command

sudo systemctl enable mongod.service

Now you can start mongodb using the following command

sudo service mongod start

This is how I did it.

private void Grid_CellClick(object sender, DataGridViewCellEventArgs e)

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

SELECT * FROM FOO WHERE FOO.BAR = 2

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

SELECT * FROM FOO ORDER BY FOO.BAR ASCENDING

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

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

fout.close()

I have the same issue. But it works properly for me

A Bin file is a pure binary file with no memory fix-ups or relocations, more than likely it has explicit instructions to be loaded at a specific memory address. Whereas....

ELF files are Executable Linkable Format which consists of a symbol look-ups and relocatable table, that is, it can be loaded at any memory address by the kernel and automatically, all symbols used, are adjusted to the offset from that memory address where it was loaded into. Usually ELF files have a number of sections, such as 'data', 'text', 'bss', to name but a few...it is within those sections where the run-time can calculate where to adjust the symbol's memory references dynamically at run-time.

We do it this way...

String.prototype.getValueByKey = function (k) {
    var p = new RegExp('\\b' + k + '\\b', 'gi');
    return this.search(p) != -1 ? decodeURIComponent(this.substr(this.search(p) + k.length + 1).substr(0, this.substr(this.search(p) + k.length + 1).search(/(&|;|$)/))) : "";
};

If you are trying to do something very similar: a is not None, the same issue comes up. That is, Numpy complains that one must use a.any or a.all.

A workaround is to do:

if not (a is None):
    pass

Not too pretty, but it does the job.

With me it worked delete this code:

@Override
    public void onAttach(Context context) {
        super.onAttach(context);
        if (context instanceof OnFragmentInteractionListener) {
            mListener = (OnFragmentInteractionListener) context;
        } else {
            throw new RuntimeException(context.toString()
                    + " must implement OnFragmentInteractionListener");
        }
    }

Ending like this:

@Override
public void onAttach(Context context) {
    super.onAttach(context);
}

There can only be one public class top level class in a file. The class name of that public class should be the name of the file. It can have many public inner classes.

You can have many classes in a single file. The limits for various levels of class visibility in a file are as follows:

Top level classes:
1 public class
0 private class
any number of default/protected classes

Inner classes:
any number of inner classes with any visibility (default, private, protected, public)

Please correct me if I am wrong.

Use "selrow" to get the selected row Id

var myGrid = $('#myGridId');

var selectedRowId = myGrid.jqGrid("getGridParam", 'selrow');

and then use getRowData to get the selected row at index selectedRowId.

var selectedRowData = myGrid.getRowData(selectedRowId);

If the multiselect is set to true on jqGrid, then use "selarrrow" to get list of selected rows:

var selectedRowIds = myGrid.jqGrid("getGridParam", 'selarrrow');

Use loop to iterate the list of selected rows:

var selectedRowData;

for(selectedRowIndex = 0; selectedRowIndex < selectedRowIds .length; selectedRowIds ++) {

   selectedRowData = myGrid.getRowData(selectedRowIds[selectedRowIndex]);

}

Did the trick for me...

The only problem with JSON in Java is that if your XML has a single child, but is an array, it will convert it to an object instead of an array. This can cause problems if you dynamically always convert from XML to JSON, where if your example XML has only one element, you return an object, but if it has 2+, you return an array, which can cause parsing issues for people using the JSON.

Infoscoop's XML2JSON class has a way of tagging elements that are arrays before doing the conversion, so that arrays can be properly mapped, even if there is only one child in the XML.

Here is an example of using it (in a slightly different language, but you can also see how arrays is used from the nodelist2json() method of the XML2JSON link).

If you have to use Relational DataBase to organize tree data structure then Postgresql has cool ltree module that provides data type for representing labels of data stored in a hierarchical tree-like structure. You can get the idea from there.(For more information see: http://www.postgresql.org/docs/9.0/static/ltree.html)

In common LDAP is used to organize records in hierarchical structure.

This standard library solution likely has not been mentioned because the question is so dated. While these answers may scale to the other use cases beyond currency where differing levels of decimals are required, it seems you need it for currency.

I recommend you use the standard library locale.currency object. It seems to have been created to address this problem of currency representation.

import locale
locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')

locale.currency(1.23)
>>>'$1.23'
locale.currency(1.53251)
>>>'$1.23'
locale.currency(1)
>>>'$1.00'

locale.currency(mealPrice)

Currency generalizes to other countries as well.

The answer that worked with me is what @Anthony had written, but you have to add another line which is

    request.SetupGet(req => req.Headers).Returns(new NameValueCollection());

so you can use this:

HttpContextFactory.Current.Request.Headers.Add(key, value);

I know move_uploaded_file has been mentioned, but file uploading in general is very dangerous. Just the presence of $_FILES should raise some concern.

It's quite possible to embed PHP code into any type of file. Images can be especially vulnerable with text comments. The problem is particularly troublesome if the code accepts the extension found within the $_FILES data as-is.

For example, a user could upload a valid PNG file with embedded PHP code as "foo.php". If the script is particularly naive, it may actually copy the file as "/uploads/foo.php". If the server is configured to allow script execution in user upload directories (often the case, and a terrible oversight), then you instantly can run any arbitrary PHP code. (Even if the image is saved as .png, it might be possible to get the code to execute via other security flaws.)

A (non-exhaustive) list of things to check on uploads:

• Make sure to analyze the contents to make sure the upload is the type it claims to be
• Save the file with a known, safe file extension that will not ever be executed
• Make sure PHP (and any other code execution) is disabled in user upload directories

In urlip3 there's no .urlopen, instead try this:

import requests
html = requests.get(url)

So far best solution that I've made:

function convertHtmlToJQueryObject(html){
    var htmlDOMObject = new DOMParser().parseFromString(html, "text/html");
    return $(htmlDOMObject.documentElement);
}

Use:

$filenameFormat = "mybackup.zip" + " " + (Get-Date -Format "yyyy-MM-dd")
Rename-Item -Path "C:\temp\mybackup.zip" -NewName $filenameFormat

jQuery.noop() can help

$(".row").each( function() {
    if (skipIteration) {
        $.noop()
    }
    else{doSomething}
});

Documenting the answer that worked for me based on the comment by @piRSquared.

I needed to convert to a string first, then an integer.

>>> df['purchase'].astype(str).astype(int)

Try this

<?php
// 1. Enter Database details
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = 'password';
$dbname = 'database name';

// 2. Create a database connection
$connection = mysql_connect($dbhost,$dbuser,$dbpass);
if (!$connection) {
    die("Database connection failed: " . mysql_error());
}

// 3. Select a database to use 
$db_select = mysql_select_db($dbname,$connection);
if (!$db_select) {
    die("Database selection failed: " . mysql_error());
}

$query = mysql_query("SELECT * FROM users WHERE name = 'Admin' ");

while ($rows = mysql_fetch_array($query)) { 
   $name = $rows['Name'];
   $address = $rows['Address'];
   $email = $rows['Email'];
   $subject = $rows['Subject'];
   $comment = $rows['Comment']

   echo "$name<br>$address<br>$email<br>$subject<br>$comment<br><br>";      
} 

?>

secure - This attribute tells the browser to only send the cookie if the request is being sent over a secure channel such as HTTPS. This will help protect the cookie from being passed over unencrypted requests. If the application can be accessed over both HTTP and HTTPS, then there is the potential that the cookie can be sent in clear text.

Updated Cian's response above to Swift 3:

func textField(textField: UITextField,shouldChangeCharactersInRange range: NSRange,replacementString string: String) -> Bool { let newCharacters = NSCharacterSet(charactersIn: string) let boolIsNumber = NSCharacterSet.decimalDigits.isSuperset(of:newCharacters as CharacterSet) if boolIsNumber == true { return true } else { if string == "." { let countdots = textField.text!.components(separatedBy:".").count - 1 if countdots == 0 { return true } else { if countdots > 0 && string == "." { return false } else { return true } } } else { return false } } }

With me the problem was solved by removing the type attribute:

<embed name="myMusic" loop="true" hidden="true" src="Music.mp3"></embed>

Cerntainly not the cleanest way.

If you're using HTML5: MP3 isn't supported by Firefox. Wav and Ogg are though. Here you can find an overview of which browser support which type of audio: http://www.w3schools.com/html/html5_audio.asp

You can bulk import all aliases from one keystore to another:

keytool -importkeystore -srckeystore source.jks -destkeystore dest.jks

You were on the right track with response.getOutputStream(), but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:

@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
    // convert JSON to Employee 
    Employee emp = convertSomehow(json);

    // generate the file
    PdfUtil.showHelp(emp);

    // retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
    byte[] contents = (...);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_PDF);
    // Here you have to set the actual filename of your pdf
    String filename = "output.pdf";
    headers.setContentDispositionFormData(filename, filename);
    headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
    ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
    return response;
}

Notes:

• use meaningful names for your methods: naming a method that writes a PDF document showHelp is not a good idea
• reading a file into a byte[]: example here
• I'd suggest adding a random string to the temporary PDF file name inside showHelp() to avoid overwriting the file if two users send a request at the same time

My answer does not require any additional libraries, and it's easy to understand. But you have to notice that if there's more than one number inside a string, my code will concatenate them together.

def search_number_string(string):
    index_list = []
    del index_list[:]
    for i, x in enumerate(string):
        if x.isdigit() == True:
            index_list.append(i)
    start = index_list[0]
    end = index_list[-1] + 1
    number = string[start:end]
    return number

I answered a similar question here

As @Syden said, the mixins will work. Another option is using SASS map-get like this..

@media (min-width: map-get($grid-breakpoints, sm)){
  .something {
    padding: 10px;
   }
}

@media (min-width: map-get($grid-breakpoints, md)){
  .something {
    padding: 20px;
   }
}

You can use this simple plugin to add scrollUp and scrollDown to your jQuery

https://github.com/phpust/JQueryScrollDetector

var lastScrollTop = 0;
var action = "stopped";
var timeout = 100;
// Scroll end detector:
$.fn.scrollEnd = function(callback, timeout) {    
      $(this).scroll(function(){
        // get current scroll top 
        var st = $(this).scrollTop();
        var $this = $(this);
        // fix for page loads
        if (lastScrollTop !=0 )
        {
            // if it's scroll up
            if (st < lastScrollTop){
                action = "scrollUp";
            } 
            // else if it's scroll down
            else if (st > lastScrollTop){
                action = "scrollDown";
            }
        }
        // set the current scroll as last scroll top
        lastScrollTop = st;
        // check if scrollTimeout is set then clear it
        if ($this.data('scrollTimeout')) {
          clearTimeout($this.data('scrollTimeout'));
        }
        // wait until timeout done to overwrite scrolls output
        $this.data('scrollTimeout', setTimeout(callback,timeout));
    });
};

$(window).scrollEnd(function(){
    if(action!="stopped"){
        //call the event listener attached to obj.
        $(document).trigger(action); 
    }
}, timeout);

if you need to limit download rate, use this code !!

<?php
$local_file = 'file.zip';
$download_file = 'name.zip';

// set the download rate limit (=> 20,5 kb/s)
$download_rate = 20.5;
if(file_exists($local_file) && is_file($local_file))
{
header('Cache-control: private');
header('Content-Type: application/octet-stream');
header('Content-Length: '.filesize($local_file));
header('Content-Disposition: filename='.$download_file);

flush();
$file = fopen($local_file, "r");
while(!feof($file))
{
    // send the current file part to the browser
    print fread($file, round($download_rate * 1024));
    // flush the content to the browser
    flush();
    // sleep one second
    sleep(1);
}
fclose($file);}
else {
die('Error: The file '.$local_file.' does not exist!');
}

?>

Like said previously, you can choose between a lot of choices, take a look at all those choices: http://kkovacs.eu/cassandra-vs-mongodb-vs-couchdb-vs-redis

What I suggest is to find your best combination: MySQL + Memcache is really great if you need ACID and you want to join some tables MongoDB + Redis is perfect for document store Neo4J is perfect for graph database

What i do: I start with MySQl + Memcache because I'm use to, then I start using others database framework. In a single project, you can combine MySQL and MongoDB for instance !

Using one of the above answers as a base, here's the Java/Android example:

protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);

    RectF bounds = new RectF(canvas.getClipBounds());
    float centerX = bounds.centerX();
    float centerY = bounds.centerY();

    float angleDeg = 90f;
    float radius = 20f

    float xPos = radius * (float)Math.cos(Math.toRadians(angleDeg)) + centerX;
    float yPos = radius * (float)Math.sin(Math.toRadians(angleDeg)) + centerY;

    //draw my point at xPos/yPos
}

Use $('textarea').val('').

The problem with using $('textarea').text('') , or $('textarea').html('') for that matter is that it will only erase what was in the original DOM sent by the server. If a user clears it and then enters new input, the clear button will no longer work. Using .val('') handles the user input case properly.

//if i input 9 it should go to 8?

You still have to work with the elements of the array. You will count 8 elements when looping through the array, but they are still going to be array(0) - array(7).

To do this using Python code:

Using importlib.metadata.version

Python =3.8

import importlib.metadata
importlib.metadata.version('beautifulsoup4')
'4.9.1'

Python =3.7

(using importlib_metadata.version)

!pip install importlib-metadata

import importlib_metadata
importlib_metadata.version('beautifulsoup4')
'4.9.1'

Using pkg_resources.Distribution

import pkg_resources
pkg_resources.get_distribution('beautifulsoup4').version
'4.9.1'
pkg_resources.get_distribution('beautifulsoup4').parsed_version
<Version('4.9.1')>

I use the following vba code where filename is a string containing the filename I want, and Function RemoveSpecialCharactersAndTruncate is defined below:

worksheet1.Name = RemoveSpecialCharactersAndTruncate(filename)

'Function to remove special characters from file before saving

    Dim IllegalCharacterSet$
    Dim i As Integer
'Set of illegal characters

    'Iterate through illegal characters and replace any instances
    For i = 1 To Len(IllegalCharacterSet) - 1
        FormattedString$ = Replace(FormattedString$, Mid(IllegalCharacterSet, i, 1), "")
    Next
    'Return the value capped at 31 characters (Excel limit)

You can use reflections

return Class.forName(className).getConstructor(String.class).newInstance(arg);

One caveat: in .NET the linefeed is "\r\n". So if you're loading your text from a file, you might have to use that instead of just "\n"

edit> as samuel pointed out in the comments, "\r\n" is not .NET specific, but is windows specific.

Let us assume that the class is Data with two objects name and dob which are both strings.

Initially, check if the list is empty. Then, add the objects from the list to a JSONArray

JSONArray allDataArray = new JSONArray();
List<Data> sList = new ArrayList<String>();

    //if List not empty
    if (!(sList.size() ==0)) {

        //Loop index size()
        for(int index = 0; index < sList.size(); index++) {
            JSONObject eachData = new JSONObject();
            try {
                eachData.put("name", sList.get(index).getName());
                eachData.put("dob", sList.get(index).getDob());
            } catch (JSONException e) {
                e.printStackTrace();
            }
            allDataArray.put(eachData);
        }
    } else {
        //Do something when sList is empty
    }

Finally, add the JSONArray to a JSONObject.

JSONObject root = new JSONObject();
    try {
        root.put("data", allDataArray);
    } catch (JSONException e) {
        e.printStackTrace();
    }

You can further get this data as a String too.

String jsonString = root.toString();

Official Ruby FAQ: What is the difference between class variables and class instance variables?

The main difference is the behavior concerning inheritance: class variables are shared between a class and all its subclasses, while class instance variables only belong to one specific class.

Class variables in some way can be seen as global variables within the context of an inheritance hierarchy, with all the problems that come with global variables. For instance, a class variable might (accidentally) be reassigned by any of its subclasses, affecting all other classes:

class Woof

  @@sound = "woof"

  def self.sound
    @@sound
  end
end

Woof.sound  # => "woof"

class LoudWoof < Woof
  @@sound = "WOOF"
end

LoudWoof.sound  # => "WOOF"
Woof.sound      # => "WOOF" (!)

Or, an ancestor class might later be reopened and changed, with possibly surprising effects:

class Foo

  @@var = "foo"

  def self.var
    @@var
  end
end

Foo.var  # => "foo" (as expected)

class Object
  @@var = "object"
end

Foo.var  # => "object" (!)

So, unless you exactly know what you are doing and explicitly need this kind of behavior, you better should use class instance variables.

If notepad is already started, you should write:

// import the function in your class
[DllImport ("User32.dll")]
static extern int SetForegroundWindow(IntPtr point);

//...

Process p = Process.GetProcessesByName("notepad").FirstOrDefault();
if (p != null)
{
    IntPtr h = p.MainWindowHandle;
    SetForegroundWindow(h);
    SendKeys.SendWait("k");
}

GetProcessesByName returns an array of processes, so you should get the first one (or find the one you want).

If you want to start notepad and send the key, you should write:

Process p = Process.Start("notepad.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");

The only situation in which the code may not work is when notepad is started as Administrator and your application is not.

The first answer covers it.

Im guessing that somewhere down the line you may decide to store your info in a different class/structure. In that case you probably wouldn't want the results going in to an array from the split() method.

You didn't ask for it, but I'm bored, so here is an example, hope it's helpful.

This might be the class you write to represent a single person:

class Person {
            public String firstName;
            public String lastName;
            public int id;
            public int age;

      public Person(String firstName, String lastName, int id, int age) {
         this.firstName = firstName;
         this.lastName = lastName;
         this.id = id;
         this.age = age;
      }  
      // Add 'get' and 'set' method if you want to make the attributes private rather than public.
} 

Then, the version of the parsing code you originally posted would look something like this: (This stores them in a LinkedList, you could use something else like a Hashtable, etc..)

try 
{
    String ruta="entrada.al";
    BufferedReader reader = new BufferedReader(new FileReader(ruta));

    LinkedList<Person> list = new LinkedList<Person>();

    String line = null;         
    while ((line=reader.readLine())!=null)
    {
        if (!(line.equals("%")))
        {
            StringTokenizer st = new StringTokenizer(line, "*");
            if (st.countTokens() == 4)          
                list.add(new Person(st.nextToken(), st.nextToken(), Integer.parseInt(st.nextToken()), Integer.parseInt(st.nextToken)));         
            else            
                // whatever you want to do to account for an invalid entry
                  // in your file. (not 4 '*' delimiters on a line). Or you
                  // could write the 'if' clause differently to account for it          
        }
    }
    reader.close();
}

You can also define a textvariable when creating the Label, and change the textvariable to update the text in the label. Here's an example:

labelText = Stringvar()
depositLabel = Label(self, textvariable=labelText)
depositLabel.grid()

def updateDepositLabel(txt) # you may have to use *args in some cases
    labelText.set(txt)

There's no need to update the text in depositLabel manually. Tk does that for you.

exciton80... I was having a problem with your code not recursing through usercontrols. It was hitting the Grid root and throwing an error. I believe this fixes it for me:

public static object[] FindControls(this FrameworkElement f, Type childType, int maxDepth)
{
    return RecursiveFindControls(f, childType, 1, maxDepth);
}

private static object[] RecursiveFindControls(object o, Type childType, int depth, int maxDepth = 0)
{
    List<object> list = new List<object>();
    var attrs = o.GetType().GetCustomAttributes(typeof(ContentPropertyAttribute), true);
    if (attrs != null && attrs.Length > 0)
    {
        string childrenProperty = (attrs[0] as ContentPropertyAttribute).Name;
        if (String.Equals(childrenProperty, "Content") || String.Equals(childrenProperty, "Children"))
        {
            var collection = o.GetType().GetProperty(childrenProperty).GetValue(o, null);
            if (collection is System.Windows.Controls.UIElementCollection) // snelson 6/6/11
            {
                foreach (var c in (IEnumerable)collection)
                {
                    if (c.GetType().FullName == childType.FullName)
                        list.Add(c);
                    if (maxDepth == 0 || depth < maxDepth)
                        list.AddRange(RecursiveFindControls(
                            c, childType, depth + 1, maxDepth));
                }
            }
            else if (collection != null && collection.GetType().BaseType.Name == "Panel") // snelson 6/6/11; added because was skipping control (e.g., System.Windows.Controls.Grid)
            {
                if (maxDepth == 0 || depth < maxDepth)
                    list.AddRange(RecursiveFindControls(
                        collection, childType, depth + 1, maxDepth));
            }
        }
    }
    return list.ToArray();
}

b = df.query('a > 1 & a < 5')

All you need to do is:

• Build the mainjava class using the class path if any (optional)

  javac *.java [ -cp "wb.jar;"]

• Create Manifest.txt file with content is:

  Main-Class: mainjava

• Package the jar file for mainjava class

  jar cfm mainjava.jar Manifest.txt *.class

Then you can run this .jar file from cmd with class path (optional) and put arguments for it.

java [-cp "wb.jar;"] mainjava arg0 arg1 

HTH.

fwiw, this didn't work for me until I had this in the ajax call:

contentType: "application/json; charset=utf-8",

using Asp.Net MVC 4.

• Refresh your tables.
• Restart the SQL server.
• Look out for the spelling mistakes in Query.

To import classes on the fly :

On OSX press Alt(Option) + Enter.

My version is like this:

php on my server:

<?php
    header('content-type: application/json; charset=utf-8');

    $data = json_encode($_SERVER['REMOTE_ADDR']);


    $callback = filter_input(INPUT_GET, 
                 'callback',
                 FILTER_SANITIZE_STRING, 
                 FILTER_FLAG_ENCODE_HIGH|FILTER_FLAG_ENCODE_LOW);
    echo $callback . '(' . $data . ');';
?>

jQuery on the page:

var self = this;
$.ajax({
    url: this.url + "getip.php",
    data: null,
    type: 'GET',
    crossDomain: true,
    dataType: 'jsonp'

}).done( function( json ) {

    self.ip = json;

});

It works cross domain. It could use a status check. Working on that.

Simple comparison of FP numbers has it's own specific and it's key is the understanding of FP format (see https://en.wikipedia.org/wiki/IEEE_floating_point)

When FP numbers calculated in a different ways, one through sin(), other though exp(), strict equality won't be working, even though mathematically numbers could be equal. The same way won't be working equality with the constant. Actually, in many situations FP numbers must not be compared using strict equality (==)

In such cases should be used DBL_EPSIPON constant, which is minimal value do not change representation of 1.0 being added to the number more than 1.0. For floating point numbers that more than 2.0 DBL_EPSIPON does not exists at all. Meanwhile, DBL_EPSILON has exponent -16, which means that all numbers, let's say, with exponent -34, would be absolutely equal in compare to DBL_EPSILON.

Also, see example, why 10.0 == 10.0000000000000001

Comparing dwo floating point numbers depend on these number nature, we should calculate DBL_EPSILON for them that would be meaningful for the comparison. Simply, we should multiply DBL_EPSILON to one of these numbers. Which of them? Maximum of course

bool close_enough(double a, double b){
    if (fabs(a - b) <= DBL_EPSILON * std::fmax(fabs(a), fabs(b)))
    {
        return true;
    }
    return false;
}

All other ways would give you bugs with inequality which could be very hard to catch

We tried a few applications, both trials of commercial products and freely available ones. Ultimately, it was the trial edition of the Team Test Load Agent software that we tried. It definitely works great and is fairly simple to use. In the long run, it bolstered our argument to move to Team Foundation Server and equip all parts of the department with the appropriate tooling.

The obvious downside, however, is the price.

You can make this bit more cleaner by using:

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

Similar to @this.lau_ answer, different approach.

The open SPF wizard from the previous answer is no longer available, neither the one from Microsoft.

Wrap the name in a span, give it a class and assign a style to that class:

<td><span class="names">Name text you want bold</span> rest of your text</td>

style:

.names { font-weight: bold; }

Edit 3

You can use the Lib : https://github.com/HaarigerHarald/android-youtubeExtractor

Ex :

String youtubeLink = "http://youtube.com/watch?v=xxxx";

new YouTubeExtractor(this) {
@Override

    if (ytFiles != null) {
        int itag = 22;
    String downloadUrl = ytFiles.get(itag).getUrl();
    }
}
}.extract(youtubeLink, true, true);

They decipherSignature using :

Why the previous answer not worked

 Pattern p2 = Pattern.compile("sig=(.*?)[&]");
        Matcher m2 = p2.matcher(url);
        String sig = null;
        if (m2.find()) {
            sig = m2.group(1);
        }

As of November 2016, this is a little rough around the edges, but displays the basic principle. The url_encoded_fmt_stream_map today does not have a space after the colon (better make this optional) and "sig" has been changed to "signature"

and while i am debuging the code i found the new keyword its signature&s in many video's URL

Some time This Code Not worked proper

Same-origin policy

https://en.wikipedia.org/wiki/Same-origin_policy

https://en.wikipedia.org/wiki/Cross-origin_resource_sharing

problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is [CORS][1]. 

Ref : https://superuser.com/questions/773719/how-do-all-of-these-save-video-from-youtube-services-work/773998#773998

url_encoded_fmt_stream_map // traditional: contains video and audio stream
adaptive_fmts              // DASH: contains video or audio stream

Each of these is a comma separated array of what I would call "stream objects". Each "stream object" will contain values like this

url  // direct HTTP link to a video
itag // code specifying the quality
s    // signature, security measure to counter downloading

Each URL will be encoded so you will need to decode them. Now the tricky part.

YouTube has at least 3 security levels for their videos

unsecured // as expected, you can download these with just the unencoded URL
s         // see below
RTMPE     // uses "rtmpe://" protocol, no known method for these

The RTMPE videos are typically used on official full length movies, and are protected with SWF Verification Type 2. This has been around since 2011 and has yet to be reverse engineered.

The type "s" videos are the most difficult that can actually be downloaded. You will typcially see these on VEVO videos and the like. They start with a signature such as

AA5D05FA7771AD4868BA4C977C3DEAAC620DE020E.0F421820F42978A1F8EAFCDAC4EF507DB5 Then the signature is scrambled with a function like this

function mo(a) {
  a = a.split("");
  a = lo.rw(a, 1);
  a = lo.rw(a, 32);
  a = lo.IC(a, 1);
  a = lo.wS(a, 77);
  a = lo.IC(a, 3);
  a = lo.wS(a, 77);
  a = lo.IC(a, 3);
  a = lo.wS(a, 44);
  return a.join("")
}

This function is dynamic, it typically changes every day. To make it more difficult the function is hosted at a URL such as

http://s.ytimg.com/yts/jsbin/html5player-en_US-vflycBCEX.js

this introduces the problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is CORS. With CORS, s.ytimg.com could add this header

Access-Control-Allow-Origin: http://www.youtube.com

and it would allow the JavaScript to download from www.youtube.com. Of course they do not do this. A workaround for this workaround is to use a CORS proxy. This is a proxy that responds with the following header to all requests

Access-Control-Allow-Origin: *

So, now that you have proxied your JS file, and used the function to scramble the signature, you can use that in the querystring to download a video.

I have try twitter geo api, failed.

Google map api, failed, so far, no way you can get city limit by any api.

twitter api geo endpoint will NOT give you city boundary,

what they provide you is ONLY bounding box with 5 point(lat, long)

this is what I get from twitter api geo for San Francisco

You can make a background occupying all the screen size transparent and listen to the onClick event to dismiss it.

A UDF will only return a value it won't allow you to change the properties of a cell/sheet/workbook. Move your code to a Worksheet_Change event or similar to change properties.

Eg

Private Sub worksheet_change(ByVal target As Range)
  target.Font.Bold = True
End Sub

bottom regex with space, supports all keyboard letters from different culture

 string input = "78-selim güzel667.,?";
 Regex regex = new Regex(@"[^\w\x20]|[\d]");
 var result= regex.Replace(input,"");
 //selim güzel

Please try that:

<script>
$(document).ready(function(){
    var add = '<tr valign="top"><th scope="row"><label for="customFieldName">Custom Field</label></th><td>';
                add+= '<input type="text" class="code" id="customFieldName" name="customFieldName[]" value="" placeholder="Input Name" />&nbsp;&nbsp;&nbsp;';
                add+= '<input type="text" class="code" id="customFieldValue" name="customFieldValue[]" value="" placeholder="Input Value" />&nbsp;';
                add+= '<a href="javascript:void(0);" class="remCF">Remove</a></td></tr>';

    $(".addCF").click(function(){ $("#customFields").append(add); });

    $("#customFields").on('click','.remCF',function(){
        var inx = $('.remCF').index(this);
        $('tr').eq(inx+1).remove();
    });
});
</script>

OK, think I can explain better what I've put in comments :). So, basically, you can see both those as the same, though DAO is a more flexible pattern than Repository. If you want to use both, you would use the Repository in your DAO-s. I'll explain each of them below:

REPOSITORY:

It's a repository of a specific type of objects - it allows you to search for a specific type of objects as well as store them. Usually it will ONLY handle one type of objects. E.g. AppleRepository would allow you to do AppleRepository.findAll(criteria) or AppleRepository.save(juicyApple). Note that the Repository is using Domain Model terms (not DB terms - nothing related to how data is persisted anywhere).

A repository will most likely store all data in the same table, whereas the pattern doesn't require that. The fact that it only handles one type of data though, makes it logically connected to one main table (if used for DB persistence).

DAO - data access object (in other words - object used to access data)

A DAO is a class that locates data for you (it is mostly a finder, but it's commonly used to also store the data). The pattern doesn't restrict you to store data of the same type, thus you can easily have a DAO that locates/stores related objects.

E.g. you can easily have UserDao that exposes methods like

Collection<Permission> findPermissionsForUser(String userId)
User findUser(String userId)
Collection<User> findUsersForPermission(Permission permission)

All those are related to User (and security) and can be specified under then same DAO. This is not the case for Repository.

Finally

Note that both patterns really mean the same (they store data and they abstract the access to it and they are both expressed closer to the domain model and hardly contain any DB reference), but the way they are used can be slightly different, DAO being a bit more flexible/generic, while Repository is a bit more specific and restrictive to a type only.

If you want to read text of any element using javascript executor, you can do something like following code:

WebElement ele = driver.findElement(By.xpath("//div[@class='infaCompositeViewTitle']"));
String assets = (String) js.executeScript("return arguments[0].getElementsByTagName('span')[1].textContent;", ele);

In this example, I have following HTML fragment and I am reading "156".

<div class="infaCompositeViewTitle">
   <span>All Assets</span>
   <span>156</span>
</div>
