Alternate solution

Create a column that will store the month:

data['month'] = data['date'].dt.month

Create a column that will store the year:

data['year'] = data['date'].dt.year

Use .AddRange to append any Enumrable collection to the list.

List<int> list = new List<int> { 5, 7, 3 };  
list.Sort((x,y)=> y.CompareTo(x));  
list.ForEach(action => { Console.Write(action + " "); });

use text transform property in your style tag

textTransform:'uppercase'

NOTE: pd.convert_objects has now been deprecated. You should use pd.Series.astype(float) or pd.to_numeric as described in other answers.

This is available in 0.11. Forces conversion (or set's to nan) This will work even when astype will fail; its also series by series so it won't convert say a complete string column

In [10]: df = DataFrame(dict(A = Series(['1.0','1']), B = Series(['1.0','foo'])))

In [11]: df
Out[11]: 
     A    B
0  1.0  1.0
1    1  foo

In [12]: df.dtypes
Out[12]: 
A    object
B    object
dtype: object

In [13]: df.convert_objects(convert_numeric=True)
Out[13]: 
   A   B
0  1   1
1  1 NaN

In [14]: df.convert_objects(convert_numeric=True).dtypes
Out[14]: 
A    float64
B    float64

How to change your global broadcast to LocalBroadcast

1) Create Instance

LocalBroadcastManager localBroadcastManager = LocalBroadcastManager.getInstance(this);

2) For registering BroadcastReceiver

Replace

registerReceiver(new YourReceiver(),new IntentFilter("YourAction"));

With

localBroadcastManager.registerReceiver(new YourReceiver(),new IntentFilter("YourAction"));

3) For sending broadcast message

Replace

sendBroadcast(intent);

With

localBroadcastManager.sendBroadcast(intent);

4) For unregistering broadcast message

Replace

unregisterReceiver(mybroadcast);

With

localBroadcastManager.unregisterReceiver(mybroadcast);

One other possible way is here.

The BeanWrapper offers functionality to set and get property values (individually or in bulk), get property descriptors, and to query properties to determine if they are readable or writable.

Company c = new Company();
 BeanWrapper bwComp = BeanWrapperImpl(c);
 bwComp.setPropertyValue("name", "your Company");

Much longer solution, but accounts for the following scenarios:

1. Is the image smaller than the bounding box?
2. Is the Image and the Bounding Box square?
3. Is the Image square and the bounding box isn't
4. Is the image wider and taller than the bounding box
5. Is the image wider than the bounding box

6. Is the image taller than the bounding box

   private Image ResizePhoto(FileInfo sourceImage, int desiredWidth, int desiredHeight)
   {
       //throw error if bouning box is to small
       if (desiredWidth < 4 || desiredHeight < 4)
           throw new InvalidOperationException("Bounding Box of Resize Photo must be larger than 4X4 pixels.");            
       var original = Bitmap.FromFile(sourceImage.FullName);
   
       //store image widths in variable for easier use
       var oW = (decimal)original.Width;
       var oH = (decimal)original.Height;
       var dW = (decimal)desiredWidth;
       var dH = (decimal)desiredHeight;
   
       //check if image already fits
       if (oW < dW && oH < dH)
           return original; //image fits in bounding box, keep size (center with css) If we made it bigger it would stretch the image resulting in loss of quality.
   
       //check for double squares
       if (oW == oH && dW == dH)
       {
           //image and bounding box are square, no need to calculate aspects, just downsize it with the bounding box
           Bitmap square = new Bitmap(original, (int)dW, (int)dH);

       if (oW == oH)
       {
           //image is square, bounding box isn't.  Get smallest side of bounding box and resize to a square of that center the image vertically and horizontally with Css there will be space on one side.
           int smallSide = (int)Math.Min(dW, dH);
           Bitmap square = new Bitmap(original, smallSide, smallSide);
           original.Dispose();
           return square;
       }
   
       //not dealing with squares, figure out resizing within aspect ratios            
       if (oW > dW && oH > dH) //image is wider and taller than bounding box
       {
           var r = Math.Min(dW, dH) / Math.Min(oW, oH); //two dimensions so figure out which bounding box dimension is the smallest and which original image dimension is the smallest, already know original image is larger than bounding box
           var nH = oH * r; //will downscale the original image by an aspect ratio to fit in the bounding box at the maximum size within aspect ratio.
           var nW = oW * r;
           var resized = new Bitmap(original, (int)nW, (int)nH);
           original.Dispose();
           return resized;
       }
       else
       {
           if (oW > dW) //image is wider than bounding box
           {
               var r = dW / oW; //one dimension (width) so calculate the aspect ratio between the bounding box width and original image width
               var nW = oW * r; //downscale image by r to fit in the bounding box...
               var nH = oH * r;
               var resized = new Bitmap(original, (int)nW, (int)nH);
               original.Dispose();
               return resized;
           }
           else
           {
               //original image is taller than bounding box

               var nH = oH * r;
               var nW = oW * r;
               var resized = new Bitmap(original, (int)nW, (int)nH);
               original.Dispose();

I think this will work even though this was forever ago.

SELECT employee_number, Row_Number()  
   OVER (PARTITION BY course_code ORDER BY course_completion_date DESC ) as rownum
FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
   AND rownum = 1

If you want to get the last Id if the date is the same then you can use this assuming your primary key is Id.

SELECT employee_number, Row_Number()  
   OVER (PARTITION BY course_code ORDER BY course_completion_date DESC, Id Desc) as rownum    FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
   AND rownum = 1

One can issue the SQL*Plus command SET TIMING ON to get wall-clock times, but one can't take, for example, fetch time out of that trivially.

The AUTOTRACE setting, when used as SET AUTOTRACE TRACEONLY will suppress output, but still perform all of the work to satisfy the query and send the results back to SQL*Plus, which will suppress it.

Lastly, one can trace the SQL*Plus session, and manually calculate the time spent waiting on events which are client waits, such as "SQL*Net message to client", "SQL*Net message from client".

For oracle:

select( 
select count(*) from foo1 where ID = '00123244552000258'
+
select count(*) from foo2 where ID = '00123244552000258'
+
select count(*) from foo3 where ID = '00123244552000258'
) total from dual;

You will need to do two steps here for a complete solution

First click on the Solution that you have open and then go File-> Source Control -> Go Online Then uncheck all the files that are being shown as being modified while you were offline.

Don't do the Get Latest version from Source Control Explorer. That will result in a dialog potentially showing a bunch of files asking you to resolve conflicts. Instead do this

In source Control explorer right click on the folder you want to get latest of and then Advanced - Get Specific Version. In the dropdown for version type choose Latest and then choose the first check box that says Overwrite writable files that are not checked out. This will automatically bring your folder in sync with latest on the server

Use it for correct result

$dom = new DOMDocument();
$dom->loadHTML('<meta http-equiv="Content-Type" content="text/html; charset=utf-8">' . $profile);
echo $dom->saveHTML();
echo $profile;

This operation

mb_convert_encoding($profile, 'HTML-ENTITIES', 'UTF-8');

It is bad way, because special symbols like &lt ; , &gt ; can be in $profile, and they will not convert twice after mb_convert_encoding. It is the hole for XSS and incorrect HTML.

No, prior to Oracle version 12.2, identifiers are not allowed to exceed 30 characters in length. See the Oracle SQL Language Reference.

However, from version 12.2 they can be up to 128 bytes long. (Note: bytes, not characters).

In case anyone is as dopey as me, double check the year of your date. I was converting a date from a text file in YYMMDD format so was creating a date with a year of 0020, not 2020. Obvious error but I spent more time looking at it but not seeing it than I should have!

To get the data of a specific field,

$form->get('fieldName')->getData();

Or for all the form data

$form->getData();

Link to docs: https://symfony.com/doc/2.7/forms.html

main() {
    double a;
    a=3669.0;
    int b;
    b=a;
    printf("b is %d",b);
  
}

output is :b is 3669

when you write b=a; then its automatically converted in int

This is called Implicit Type Conversion Read more here https://www.geeksforgeeks.org/implicit-type-conversion-in-c-with-examples/

you can set android theme of the checkbox to get the color you want in your styles.xml add :

<style name="checkBoxStyle" parent="Base.Theme.AppCompat">
    <item name="colorAccent">CHECKEDHIGHLIGHTCOLOR</item>
    <item name="android:textColorSecondary">UNCHECKEDCOLOR</item>
</style>

then in your layout file :

<CheckBox
     android:theme="@style/checkBoxStyle"
     android:id="@+id/chooseItemCheckBox"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"/>

unlike using android:buttonTint="@color/CHECK_COLOR" this method works under Api 23

It is absolutely possible to install side-by-side several JRE/JDK versions. Moreover, you don't have to do anything special for that to happen, as Sun is creating a different folder for each (under Program Files).

There is no control panel to check which JRE works for each application. Basically, the JRE that will work would be the first in your PATH environment variable. You can change that, or the JAVA_HOME variable, or create specific cmd/bat files to launch the applications you desire, each with a different JRE in path.

You can try just putting the image in the source directory. You'd link it by replacing the file path with src="../imagenamehere.fileextension In your case, j3evn.jpg.

This error occurred in my application with the CIP-protocol whenever I didn't Send or received data in less than 10s.

This was caused by the use of the forward open method. You can avoid this by working with an other method, or to install an update rate of less the 10s that maintain your forward-open-connection.

there are some process which cannot be kill like this "kill %1" . if we have to terminate that process so special command is used to kill that process which is kill -9. eg open vim and stop if by using ctrl+z then see jobs and after apply kill process than this process will not terminated so here we use kill -9 command for terminating.

For Exact Match

"SELECT * FROM yourTable WHERE city = 'c7'"

For Pattern / Wildcard Search

"SELECT * FROM yourTable WHERE city LIKE '%c7%'"

Of course you can change '%c7%' to '%c7' or 'c7%' depending on how you want to search it. For exact match, use first query example.

PHP

$result = mysql_query("SELECT * FROM yourTable WHERE city = 'c7'");
$matchFound = mysql_num_rows($result) > 0 ? 'yes' : 'no';
echo $matchFound;

You can also use if condition there.

Create an ouput

<div id="output"></div>

Write to it using JavaScript

var output = document.getElementById("output");
output.innerHTML = "hello world";

If you would like it to handle more complex output values, you can use JSON.stringify

var myObj = {foo: "bar"};
output.innerHTML = JSON.stringify(myObj);

you can add the class .datepicker in a javascript function, to be able to dynamically change the input type

 $("#ddlDefault").addClass("datepicker");
 $(".datepicker").datetimepicker({ timepicker: false, format: 'd/m/Y', });

Another alternative

for(String serverId : serverIds) {
   sb.append(",");
   sb.append(serverId); 
}
sb.deleteCharAt(0);

you can do something like that:

where regexp_like(name, 'string$', 'i');

You can use filter() to do that:

var tableRow = $("td").filter(function() {
    return $(this).text() == "foo";
}).closest("tr");

According to JavaDocs, you can do this:

WebElement input = divA.findElement(By.xpath(".//input"));

How can I ask in xpath for "the div-tag that contains a span with the text 'hello world'"?

WebElement elem = driver.findElement(By.xpath("//div[span[text()='hello world']]"));

The XPath spec is a suprisingly good read on this.

It may be useful to you to simply increase the number of results that get displayed

In the mongo shell > DBQuery.shellBatchSize = 3000

and then you can select all the results out of the terminal in one go and paste into a text file.

It is what I am going to do :)

(from : https://stackoverflow.com/a/3705615/1290746)

This might work for you (GNU sed):

sed -r '1{x;s/^/:abbc:bcab/;x};G;s/^/\n/;:a;/\n\n/{P;d};s/\n(ab|bc)(.*\n.*:(\1)([^:]*))/\4\n\2/;ta;s/\n(.)/\1\n/;ta' file

This uses a lookup table which is prepared and held in the hold space (HS) and then appended to each line. An unique marker (in this case \n) is prepended to the start of the line and used as a method to bump-along the search throughout the length of the line. Once the marker reaches the end of the line the process is finished and is printed out the lookup table and markers being discarded.

N.B. The lookup table is prepped at the very start and a second unique marker (in this case :) chosen so as not to clash with the substitution strings.

With some comments:

sed -r '
  # initialize hold with :abbc:bcab
  1 {
    x
    s/^/:abbc:bcab/
    x
  }

  G        # append hold to patt (after a \n)

  s/^/\n/  # prepend a \n

  :a

  /\n\n/ {
    P      # print patt up to first \n
    d      # delete patt & start next cycle
  }

  s/\n(ab|bc)(.*\n.*:(\1)([^:]*))/\4\n\2/
  ta       # goto a if sub occurred

  s/\n(.)/\1\n/  # move one char past the first \n
  ta       # goto a if sub occurred
'

The table works like this:

   **   **   replacement
:abbc:bcab
 **   **     pattern

Sum up best answers:

1. Eliminate emtpties WITHOUT stripping:

That is, all-space strings are retained:

slist = list(filter(None, slist))

PROs:

• simplest;
• fastest (see benchmarks below).

2. To eliminate empties after stripping ...

2.a ... when strings do NOT contain spaces between words:

slist = ' '.join(slist).split()

PROs:

• small code
• fast (BUT not fastest with big datasets due to memory, contrary to what @paolo-melchiorre results)

2.b ... when strings contain spaces between words?

slist = list(filter(str.strip, slist))

PROs:

• fastest;
• understandability of the code.

I think you want to give Share button, clicking on which the suitable media/website option should be there to share with it. In Android, you need to create createChooser for the same.

Sharing Text:

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "This is the text that will be shared.");
startActivity(Intent.createChooser(sharingIntent,"Share using"));

Sharing binary objects (Images, videos etc.)

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri screenshotUri = Uri.parse(path);

sharingIntent.setType("image/png");
sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
startActivity(Intent.createChooser(sharingIntent, "Share image using"));

FYI, above code are referred from Sharing content in Android using ACTION_SEND Intent

I think I got what I was looking for..

Try that:

/bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024

/sbin/mkswap /var/swap.1

/sbin/swapon /var/swap.1

Try...

$("#captureAudio").prop('checked', false); 

You can use

My answer below shows how to embed images using data URIs. This is useful for the web, but will not work reliably for most email clients. For email purposes be sure to read Shadow2531's answer.

Base-64 data is legal in an img tag and I believe your question is how to properly insert such an image tag.

You can use an online tool or a few lines of code to generate the base 64 string.

The syntax to source the image from inline data is:

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA
AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO

Delete old configuration files from c:\Users\username\AppData\Local\appname and c:\Users\username\AppData\Roaming\appname and then try to restart your application.

Well in fact TryGetValue is faster. How much faster? It depends on the dataset at hand. When you call the Contains method, Dictionary does an internal search to find its index. If it returns true, you need another index search to get the actual value. When you use TryGetValue, it searches only once for the index and if found, it assigns the value to your variable.

Edit:

Ok, I understand your confusion so let me elaborate:

Case 1:

if (myDict.Contains(someKey))
     someVal = myDict[someKey];

In this case there are 2 calls to FindEntry, one to check if the key exists and one to retrieve it

Case 2:

myDict.TryGetValue(somekey, out someVal)

In this case there is only one call to FindKey because the resulting index is kept for the actual retrieval in the same method.

Couldn't you just do something simple like this?

For i = LBound(Schedule, 1) To UBound(Schedule, 1)
  If (Schedule(i, 1) < ReferenceDate) Then
     PrevCouponIndex = i
  Else
     DF = Application.Run("SomeFunction"....)
     PV = PV + (DF * Coupon / CouponFrequency)
  End If

I found an easier way by looking at the R script generated by Rattle. It looks like below:

Sorry for the short answer but it is late. Google "oracle event 10046 sql trace". It would be best to trace an individual session because figuring which SQL belongs to which session from v$sql is no easy if it is shared sql and being used by multiple users.

If you want to impress your Oracle DBA friends, learn how to set an oracle trace with event 10046, interpret the meaning of the wait events and find the top cpu consumers.

Quest had a free product that allowed you to capture the SQL as it went out from the client side but not sure if it works with your product/version of Oracle. Google "quest oracle sql monitor" for this.

Good night.

AdBlockers usually have some rules, i.e. they match the URIs against some type of expression (sometimes they also match the DOM against expressions, not that this matters in this case).

Having rules and expressions that just operate on a tiny bit of text (the URI) is prone to create some false-positives...

Besides instructing your users to disable their extensions (at least on your site) you can also get the extension and test which of the rules/expressions blocked your stuff, provided the extension provides enough details about that. Once you identified the culprit, you can either try to avoid triggering the rule by using different URIs, report the rule as incorrect or overly-broad to the team that created it, or both. Check the docs for a particular add-on on how to do that.

For example, AdBlock Plus has a Blockable items view that shows all blocked items on a page and the rules that triggered the block. And those items also including XHR requests.

If you have any NamedQueries in your entity classes, then check the stack trace for compilation errors. A malformed query which cannot be compiled can cause failure to load the persistence context.

1. Function imageMorph will create a new img element therefore the id is removed. Changed to

   $("#wrapper > img")

2. You should use live() function for click event if you want you rocket lanch again.

"pull-right" class may not be the right way because in uses "float: right" instead of text-align.

Checking the bootstrap 3 css file i found "text-right" class on line 457. This class should be the right way to align the text to the right.

Some code:

<div class="row">
    <div class="col-xs-12">
        <div class="text-right">
            <button type="button" class="btn btn-default">Default</button>
        </div>
    </div>
</div>

l = []
x = 0
l.extend([x]*100)

Instead of casting to float you can do following

def mean(nums):
    return sum(nums, 0.0) / len(nums)

or using lambda

mean = lambda nums: sum(nums, 0.0) / len(nums)

UPDATES: 2019-12-15

Python 3.8 added function fmean to statistics module. Which is faster and always returns float.

Convert data to floats and compute the arithmetic mean.

This runs faster than the mean() function and it always returns a float. The data may be a sequence or iterable. If the input dataset is empty, raises a StatisticsError.

fmean([3.5, 4.0, 5.25])

4.25

New in version 3.8.

If you install PHP with homebrew, you can switch between versions very easily. Say you want php56 to point to Version 5.6.17, you just do:

brew switch php56 5.6.17

UPDATE

For security reasons, it is recommended to use sanitize instead of html_safe.

<%= sanitize @str %>

What's happening is that, as a security measure, Rails is escaping your string for you because it might have malicious code embedded in it. But if you tell Rails that your string is html_safe, it'll pass it right through.

@str = "<b>Hi</b>".html_safe
<%= @str %>

OR

@str = "<b>Hi</b>"
<%= @str.html_safe %>

Using raw works fine, but all it's doing is converting the string to a string, and then calling html_safe. When I know I have a string, I prefer calling html_safe directly, because it skips an unnecessary step and makes clearer what's going on. Details about string-escaping and XSS protection are in this Asciicast.

Here is an improved version of the function from php.net that @Andrew posted.

        $name = md5(uniqid() . microtime(TRUE) . mt_rand()). '.csv';
    }

    header('Content-Type: text/csv');
    header('Content-Disposition: attachment; filename='. $name);
    header('Pragma: no-cache');
    header("Expires: 0");

    $outstream = fopen("php://output", "wb");

    foreach($results as $result)
    {
        fputcsv($outstream, $result);
    }

    fclose($outstream);
}

It is really easy to use and works great with MySQL(i)/PDO result sets.

download_csv_results($results, 'your_name_here.csv');

Remember to exit() after calling this if you are done with the page.

You need that it breaks the outer if statement. Why do you use second else?

IF condition THEN  
    IF condition THEN 
        sequence 1
    // ELSE sequence 4
       // break //?  
    // ENDIF    
ELSE    
    sequence 3    
ENDIF

sequence 4

public static List<Product> getCartList() {

    JSONObject responseDetailsJson = new JSONObject();
    JSONArray jsonArray = new JSONArray();

    List<Product> cartList = new Vector<Product>(cartMap.keySet().size());
    for(Product p : cartMap.keySet()) {
        cartList.add(p);
        JSONObject formDetailsJson = new JSONObject();
        formDetailsJson.put("id", "1");
        formDetailsJson.put("name", "name1");
       jsonArray.add(formDetailsJson);
    }
    responseDetailsJson.put("forms", jsonArray);//Here you can see the data in json format

    return cartList;

}

you can get the data in the following form

{
    "forms": [
        { "id": "1", "name": "name1" },
        { "id": "2", "name": "name2" } 
    ]
}

You can also force to table columns in table using force: true, if you table is already exist.

example:

ActiveRecord::Schema.define(version: 20080906171750) do
  create_table "authors", force: true do |t|
    t.string   "name"
    t.datetime "created_at"
    t.datetime "updated_at"
  end
end

try using

background-color: none;

that worked for me.

There is also:

info all-registers

Then you can get the register name you are interested in -- very useful for finding platform-specific registers (like NEON Q... on ARM).

Turning Marc Gravell's answer into an extension method, I made the following.

internal static IEnumerable<Tuple<TLeft, TRight>> LeftJoin<TLeft, TRight, TKey>(
    this IEnumerable<TLeft> left,
    IEnumerable<TRight> right,
    Func<TLeft, TKey> selectKeyLeft,
    Func<TRight, TKey> selectKeyRight,
    TRight defaultRight = default(TRight),
    IEqualityComparer<TKey> cmp = null)
{
    return left.GroupJoin(
            right,
            selectKeyLeft,
            selectKeyRight,
            (x, y) => new Tuple<TLeft, IEnumerable<TRight>>(x, y),
            cmp ?? EqualityComparer<TKey>.Default)
        .SelectMany(
            x => x.Item2.DefaultIfEmpty(defaultRight),
            (x, y) => new Tuple<TLeft, TRight>(x.Item1, y));
}

UPDATE: As TimK pointed out, this isn't needed with jquery 1.5.2 any more. But if you want to add custom headers or allow the use of credentials (username, password, or cookies, etc), read on.

I think I found the answer! (4 hours and a lot of cursing later)

//This does not work!!
Access-Control-Allow-Headers: *

You need to manually specify all the headers you will accept (at least that was the case for me in FF 4.0 & Chrome 10.0.648.204).

jQuery's $.ajax method sends the "x-requested-with" header for all cross domain requests (i think its only cross domain).

So the missing header needed to respond to the OPTIONS request is:

//no longer needed as of jquery 1.5.2
Access-Control-Allow-Headers: x-requested-with

If you are passing any non "simple" headers, you will need to include them in your list (i send one more):

//only need part of this for my custom header
Access-Control-Allow-Headers: x-requested-with, x-requested-by

So to put it all together, here is my PHP:

// * wont work in FF w/ Allow-Credentials
//if you dont need Allow-Credentials, * seems to work
header('Access-Control-Allow-Origin: http://www.example.com');
//if you need cookies or login etc
header('Access-Control-Allow-Credentials: true');
if ($this->getRequestMethod() == 'OPTIONS')
{
  header('Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS');
  header('Access-Control-Max-Age: 604800');
  //if you need special headers
  header('Access-Control-Allow-Headers: x-requested-with');
  exit(0);
}

Usually, activating a virtualenv gives you a shell function named:

$ deactivate

which puts things back to normal.

I have just looked specifically again at the code for virtualenvwrapper, and, yes, it too supports deactivate as the way to escape from all virtualenvs.

If you are trying to leave an Anaconda environment, the command depends upon your version of conda. Recent versions (like 4.6) install a conda function directly in your shell, in which case you run:

conda deactivate

Older conda versions instead implement deactivation using a stand-alone script:

source deactivate

It allows servlets to have multiple servlet mappings:

<servlet>
    <servlet-name>Servlet1</servlet-name>
    <servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/bill</url-pattern>
</servlet-mapping>

It allows filters to be mapped on the particular servlet:

<filter-mapping>
    <filter-name>Filter1</filter-name>
    <servlet-name>Servlet1</servlet-name>
</filter-mapping>

Your proposal would support neither of them. Note that the web.xml is read and parsed only once during application's startup, not on every HTTP request as you seem to think.

Since Servlet 3.0, there's the @WebServlet annotation which minimizes this boilerplate:

@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {

Running:

npm install

from inside your app directory (i.e. where package.json is located) will install the dependencies for your app, rather than install it as a module, as described here. These will be placed in ./node_modules relative to your package.json file (it's actually slightly more complex than this, so check the npm docs here).

You are free to move the node_modules dir to the parent dir of your app if you want, because node's 'require' mechanism understands this. However, if you want to update your app's dependencies with install/update, npm will not see the relocated 'node_modules' and will instead create a new dir, again relative to package.json.

To prevent this, just create a symlink to the relocated node_modules from your app dir:

ln -s ../node_modules node_modules

I got this error too even I ran cmd as an Administrator.

The root cause is: The file is from VCS(subversion, perforce, etc.), and when I checked the properties of this file, its' Attributes is Read-only.

So the solution is:

• (1) disable the 'Read-only' Attribute;
• (2) check out from VCS, let the file under the status of read&write.

Below is code snippet you can use to delete the bucket,

import boto3, botocore
from botocore.exceptions import ClientError

s3 = boto3.resource("s3",aws_access_key_id='Your-Access-Key',aws_secret_access_key='Your-Secret-Key')
s3.Object('Bucket-Name', 'file-name as key').delete()

I built on sabithpocker's idea and made a more generalized version that lets you control more than one selectbox from a given trigger.

I assigned the selectboxes I wanted to be controlled the classname "switchable," and cloned them all like this:

$j(this).data('options',$j('select.switchable option').clone());

and used a specific naming convention for the switchable selects, which could also translate into classes. In my case, "category" and "issuer" were the select names, and "category_2" and "issuer_1" the class names.

Then I ran an $.each on the select.switchable groups, after making a copy of $(this) for use inside the function:

var that = this;
$j("select.switchable").each(function() { 
    var thisname = $j(this).attr('name');
    var theseoptions = $j(that).data('options').filter( '.' + thisname + '_' + id );
    $j(this).html(theseoptions);
});     

By using a classname on the ones you want to control, the function will safely ignore other selects elsewhere on the page (such as the last one in the example on Fiddle).

Here's a Fiddle with the complete code:

shell_exec('mv filename dest_filename');

As just formulated by grepsedawk, the answer lies in the -l option of g++, calling ld. If you look at the man page of this command, you can either do:

• g++ -l:libmagic.so.1 [...]
• or: g++ -lmagic [...] , if you have a symlink named libmagic.so in your libs path

About promise composition vs. Rxjs, as this is a frequently asked question, you can refer to a number of previously asked questions on SO, among which :

• How to do the chain sequence in rxjs
• RxJS Promise Composition (passing data)
• RxJS sequence equvalent to promise.then()?

Basically, flatMap is the equivalent of Promise.then.

For your second question, do you want to replay values already emitted, or do you want to process new values as they arrive? In the first case, check the publishReplay operator. In the second case, standard subscription is enough. However you might need to be aware of the cold. vs. hot dichotomy depending on your source (cf. Hot and Cold observables : are there 'hot' and 'cold' operators? for an illustrated explanation of the concept)

You can use the .tostring() method with datetime format specifiers to format to whatever you need:

http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx

(Get-Date).AddDays(-1).ToString('MM-dd-yyyy')

The keys are maintained with the removed key missing but they can be rearranged by doing this:

$array = array(1,2,3,4,5);
unset($array[2]);
$arranged = array_values($array);
print_r($arranged);

Outputs:

Array
(
    [0] => 1
    [1] => 2
    [2] => 4
    [3] => 5
)

Notice that if we do the following without rearranging:

unset($array[2]);
$array[]=3;

The index of the value 3 will be 5 because it will be pushed to the end of the array and will not try to check or replace missing index. This is important to remember when using FOR LOOP with index access.

This css solution worked for me:

input:active,
input:focus {
    border: 1px solid #red
}

input:active,
input:focus {
    padding: 2px solid #red /*for firefox and chrome*/
}

/* .ie is a class you would need to set at the html root level */
.ie input:active,
.ie input:focus {
    padding: 3px solid #red /* IE needs 1px extra padding*/
}

I understand it is not necessary on FF and Chrome, but IE needs it. And there are circumstances when you need it.

Today available Angular 2 rc.7, and I had a similar problem with [email protected] UNMET PEER DEPENDENCY.

If you, like me, simply replaced @angular/...rc.6 to @angular/...rc.7 - it's not enough. Because, for example, @angular/router has no rc.6 version.

In this case, better review package.json in Quick start

If you can't or don't want to use any AJAX stuff, use an iframe or ten! ;) You can have processes running in iframes in parallel with the master page without worrying about cross browser comparable issues or syntax issues with dot net AJAX etc, and you can call the master page's JavaScript (including the JavaScript that it has imported) from an iframe.

E.g, in a parent iframe, to call egFunction() in the parent document once the iframe content has loaded (that's the asynchronous part)

parent.egFunction();

Dynamically generate the iframes too so the main html code is free from them if you want.

\n = LF (Line Feed) // Used as a new line character on Unix

\r = CR (Carriage Return) // Used as a new line character on Mac

\r\n = CR + LF // Used as a new line character on Windows

(char)13 = \r = CR

Environment.NewLine = any of the above code based on the operating system

// .NET provides the Environment class which provides many data based on operating systems, so if the application is built on Windows, and you use CR + LF ("\n\r" instead of Environment.NewLine) as the new line character in your strings, and then Microsoft creates a VM for running .NET applications in Unix, then there will be problem. So, you should always use Environment.NewLine when you want a new line character. Now you need not to care about the operating system.

try

System.IO.Path.GetFileNameWithoutExtension(path); 

demo

string fileName = @"C:\mydir\myfile.ext";
string path = @"C:\mydir\";
string result;

result = Path.GetFileNameWithoutExtension(fileName);
Console.WriteLine("GetFileNameWithoutExtension('{0}') returns '{1}'", 
    fileName, result);

result = Path.GetFileName(path);
Console.WriteLine("GetFileName('{0}') returns '{1}'", 
    path, result);

// This code produces output similar to the following:
//
// GetFileNameWithoutExtension('C:\mydir\myfile.ext') returns 'myfile'
// GetFileName('C:\mydir\') returns ''

Also got the same error when using ajax.

If you're using ajax to render forms with select2, the input_html class must be different from those NOT rendered using ajax. Not quite sure why it works this way though.

Does this answer your question?

I have never used reinterpret_cast, and wonder whether running into a case that needs it isn't a smell of bad design. In the code base I work on dynamic_cast is used a lot. The difference with static_cast is that a dynamic_cast does runtime checking which may (safer) or may not (more overhead) be what you want (see msdn).

My Code to insert data is not working. It showing no error but data is not showing in my database.

public partial class Form1 : Form { OleDbConnection connection = new OleDbConnection(check.Properties.Settings.Default.KitchenConnectionString); public Form1() { InitializeComponent(); }

    private void Form1_Load(object sender, EventArgs e)
    {
        
    }

    private void btn_add_Click(object sender, EventArgs e)
    {
        OleDbDataAdapter items = new OleDbDataAdapter();
        connection.Open();
        OleDbCommand command = new OleDbCommand("insert into Sets(SetId, SetName,  SetPassword) values('"+txt_id.Text+ "','" + txt_setname.Text + "','" + txt_password.Text + "');", connection);
        command.CommandType = CommandType.Text;
        command.ExecuteReader();
        connection.Close();
        MessageBox.Show("Insertd!");
    }
}

Just for anyone who still has an issue, I also had an issue where I typed ngif rather than ngIf (notice the capital 'I').

C# 8 enhancements of pattern matching made it possible to do it like this. In some cases it do the job and more concise.

        public Animal Animal { get; set; }
        ...
        var animalName = Animal switch
        {
            Cat cat => "Tom",
            Mouse mouse => "Jerry",
            _ => "unknown"
        };

1. Choice

If you git and GitHub user:

generate-package more simply, than npm init.

else

and/or you don't like package.json template, that generate-package or npm init generate:

you can generate your own template via scaffolding apps as generate, sails or yeoman.

2. Relevance

This answer is relevant for March 2018. In the future, the data from this answer may be obsolete.

Author of this answer personally used generate-package at March 2018.

3. Limitations

You need use git and GitHub for using generate-package.

4. Demonstration

For example, I create blank folder sasha-npm-init-vs-generate-package.

This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.

See `npm help json` for definitive documentation on these fields
and exactly what they do.

Use `npm install <pkg>` afterwards to install a package and
save it as a dependency in the package.json file.

I think, that generate-package more simply, that npm init.

5. Customizing

That create your own package.json template, see generate and yeoman examples.

I'd recommend using nlargest for better performance and shorter code. import pandas

df[col_name].value_counts().nlargest(n=1)

Another use:

SET ROWCOUNT 1000 -- Buffer

DECLARE @DATE AS DATETIME = dateadd(MONTH,-7,GETDATE())

DELETE LargeTable  WHERE readTime < @DATE
WHILE @@ROWCOUNT > 0
BEGIN
   DELETE LargeTable  WHERE readTime < @DATE
END
SET ROWCOUNT 0

Optional;

If transaction log is enabled, disable transaction logs.

ALTER DATABASE dbname SET RECOVERY SIMPLE;

If you get this error with Firebase Cloud Functions, this is due to the limitations of the free tier (outbound networking only allowed to Google services).

Upgrade to the Flame or Blaze plans for it to work.

var dn = await Task.WhenAll<dynamic>(FeedCat(),SellHouse(),BuyCar());

if you want to access Cat, you do this:

var ct = (Cat)dn[0];

This is very simple to do and very useful to use, there is no need to go after a complex solution.

There would be two ways to define constants - const and static final, with the exact same semantics. Furthermore static final describes the behaviour better than const

You have to compile with Java 1.7. But if you have *.jsp files, you should also completely remove Java 1.8 from the system. If you use Mac, here is how you can do it.

Answering your question - use contextmenu event, like below:

if (document.addEventListener) {_x000D_
  document.addEventListener('contextmenu', function(e) {_x000D_
    alert("You've tried to open context menu"); //here you draw your own menu_x000D_
    e.preventDefault();_x000D_
  }, false);_x000D_
} else {_x000D_
  document.attachEvent('oncontextmenu', function() {_x000D_
    alert("You've tried to open context menu");_x000D_
    window.event.returnValue = false;_x000D_
  });_x000D_
}

<body>_x000D_
  Lorem ipsum..._x000D_
</body>

But you should ask yourself, do you really want to overwrite default right-click behavior - it depends on application that you're developing.

JSFIDDLE

Recent I have met several times of stop abnormal. Although shutdown.sh provides some information, The situations are:

• result of the command ps -ef| grep java is Null.
• result of the command ps -ef| grep java is not null.

My opinion is just kill the process of Catalina and remove the pid file (In your situation is /opt/tomcat/work/catalina.pid.)

The result seems not so seriously to influence others.

If you really don't want to change your structure, or at least create a copy of it containing the same data (e.g. make a class property with a setter and getter that read from/write to that string behind the scenes), then you can use a regular expression to check if an item is in that "list" at any given time, and if not, append it to the "list" as a separate element.

if not re.match("\b{}\b".format(348521), some_list[0]): some_list.append(348521)

This is probably faster than converting it to a set every time you want to check if an item is in it. But using set as others have suggested here is a million times better.

You have to store the timer id of the interval when you start it, you will use this value later to stop it, using the clearInterval function:

$(function () {
  var timerId = 0;

  $('textarea').focus(function () {
    timerId = setInterval(function () {
      // interval function body
    }, 1000);
  });

  $('textarea').blur(function () {
    clearInterval(timerId);
  });

});

There is a difference.

When the ^ character appears outside of [] matches the beginning of the line (or string). When the ^ character appears inside the [], it matches any character not appearing inside the [].

I'd also suggest moving the event handler outside render.

var OnSubmitTest = React.createClass({

  submit: function(e){
    e.preventDefault();
    alert('it works!');
  }

  render: function() {
    return (
      <form onSubmit={this.submit}>
        <button>Click me</button>
      </form>
    );
  }
});

A very simple way to read an external script into an sqlite database in python is using executescript():

import sqlite3

conn = sqlite3.connect('csc455_HW3.db')

with open('ZooDatabase.sql', 'r') as sql_file:
    conn.executescript(sql_file.read())

conn.close()

Time time = new Time();
time.setToNow();
System.out.println("time: " + time.hour+":"+time.minute);

This will give you, for example, 12:32.

Remember to import android.text.format.Time;

I think the best approach is to use a combination, Your second approach seems to be an elegant solution where browsers are involved.

So depending on the how the call is made. (whether its a browser or a web service call) you can use a combination of the two, with sending a URL to the browser and sending raw data to any other web service client.

It's subtle.

If the business requirement is "I want to audit the changes to the data - who did what and when?", you can usually use audit tables (as per the trigger example Keethanjan posted). I'm not a huge fan of triggers, but it has the great benefit of being relatively painless to implement - your existing code doesn't need to know about the triggers and audit stuff.

If the business requirement is "show me what the state of the data was on a given date in the past", it means that the aspect of change over time has entered your solution. Whilst you can, just about, reconstruct the state of the database just by looking at audit tables, it's hard and error prone, and for any complicated database logic, it becomes unwieldy. For instance, if the business wants to know "find the addresses of the letters we should have sent to customers who had outstanding, unpaid invoices on the first day of the month", you likely have to trawl half a dozen audit tables.

Instead, you can bake the concept of change over time into your schema design (this is the second option Keethanjan suggests). This is a change to your application, definitely at the business logic and persistence level, so it's not trivial.

For example, if you have a table like this:

CUSTOMER
---------
CUSTOMER_ID PK
CUSTOMER_NAME
CUSTOMER_ADDRESS

and you wanted to keep track over time, you would amend it as follows:

CUSTOMER
------------
CUSTOMER_ID            PK
CUSTOMER_VALID_FROM    PK
CUSTOMER_VALID_UNTIL   PK
CUSTOMER_STATUS
CUSTOMER_USER
CUSTOMER_NAME
CUSTOMER_ADDRESS

Every time you want to change a customer record, instead of updating the record, you set the VALID_UNTIL on the current record to NOW(), and insert a new record with a VALID_FROM (now) and a null VALID_UNTIL. You set the "CUSTOMER_USER" status to the login ID of the current user (if you need to keep that). If the customer needs to be deleted, you use the CUSTOMER_STATUS flag to indicate this - you may never delete records from this table.

That way, you can always find what the status of the customer table was for a given date - what was the address? Have they changed name? By joining to other tables with similar valid_from and valid_until dates, you can reconstruct the entire picture historically. To find the current status, you search for records with a null VALID_UNTIL date.

It's unwieldy (strictly speaking, you don't need the valid_from, but it makes the queries a little easier). It complicates your design and your database access. But it makes reconstructing the world a lot easier.

GitLab 12.1 (July 2019) introduces a difference:

"Merge Requests for Confidential Issues"

When discussing, planning and resolving confidential issues, such as security vulnerabilities, it can be particularly challenging for open source projects to remain efficient since the Git repository is public.

As of 12.1, it is now possible for confidential issues in a public project to be resolved within a streamlined workflow using the Create confidential merge request button, which helps you create a merge request in a private fork of the project.

See "Confidential issues" from issue 58583.

A similar feature exists in GitHub, but involves the creation of a special private fork, called "maintainer security advisory".

GitLab 13.5 (Oct. 2020) will add reviewers, which was already available for GitHub before.

Try this:

$(this).hide("slide", { direction: "left" }, 1000);

$(this).show("slide", { direction: "left" }, 1000);

Probably, it will not matter at all. Read this post on Coding Horror ;): http://www.codinghorror.com/blog/archives/001218.html

Subclassing dict is one method, though not efficient. Here if you supply an integer it will return d[list(d)[n]], otherwise access the dictionary as expected:

class mydict(dict):
    def __getitem__(self, value):
        if isinstance(value, int):
            return self.get(list(self)[value])
        else:
            return self.get(value)

d = mydict({'a': 'hello', 'b': 'this', 'c': 'is', 'd': 'a',
            'e': 'test', 'f': 'dictionary', 'g': 'testing'})

d[0]    # 'hello'
d[1]    # 'this'
d['c']  # 'is'

They don't have similar meanings. 'src' indicates a resource the browser should fetch as part of the current page. HREF indicatea a resource to be fetched if the user requests it.

    IF CHARINDEX('TextToSearch',@TextWhereISearch, 0) > 0 => TEXT EXISTS

    IF PATINDEX('TextToSearch', @TextWhereISearch) > 0 => TEXT EXISTS

    Additionally we can also use LIKE but I usually don't use LIKE.

In Jackson 2.4, you can convert as follows:

MyClass newJsonNode = jsonObjectMapper.treeToValue(someJsonNode, MyClass.class);

where jsonObjectMapper is a Jackson ObjectMapper.

In older versions of Jackson, it would be

MyClass newJsonNode = jsonObjectMapper.readValue(someJsonNode, MyClass.class);

One more solution is to use contains which will return true or false

_.contains($(".right-tree").css("background-image"), "stage1")

Hope this helps

<div id="canvasdiv" style="margin: 5px; height: 100%; width: 100%;">
    <canvas id="mycanvas" style="border: 1px solid red;"></canvas>
</div>
<script>
$(function(){
    InitContext();
});
function InitContext()
{
var $canvasDiv = $('#canvasdiv');

var canvas = document.getElementById("mycanvas");
canvas.height = $canvasDiv.innerHeight();
canvas.width = $canvasDiv.innerWidth();
}
</script>

Check your permissions first of all on the file, to make sure you can a) see it from your script, and b) are able to delete it.

You can also use a path calculated from the directory you're currently running the script in, eg:

unlink(dirname(__FILE__) . "/../../public_files/" . $filename);

(in PHP 5.3 I believe you can use the __DIR__ constant instead of dirname() but I've not used it myself yet)

If you want plain C exports, use a C project not C++. C++ DLLs rely on name-mangling for all the C++isms (namespaces etc...). You can compile your code as C by going into your project settings under C/C++->Advanced, there is an option "Compile As" which corresponds to the compiler switches /TP and /TC.

If you still want to use C++ to write the internals of your lib but export some functions unmangled for use outside C++, see the second section below.

Exporting/Importing DLL Libs in VC++

What you really want to do is define a conditional macro in a header that will be included in all of the source files in your DLL project:

#ifdef LIBRARY_EXPORTS
#    define LIBRARY_API __declspec(dllexport)
#else
#    define LIBRARY_API __declspec(dllimport)
#endif

Then on a function that you want to be exported you use LIBRARY_API:

LIBRARY_API int GetCoolInteger();

In your library build project create a define LIBRARY_EXPORTS this will cause your functions to be exported for your DLL build.

Since LIBRARY_EXPORTS will not be defined in a project consuming the DLL, when that project includes the header file of your library all of the functions will be imported instead.

If your library is to be cross-platform you can define LIBRARY_API as nothing when not on Windows:

#ifdef _WIN32
#    ifdef LIBRARY_EXPORTS
#        define LIBRARY_API __declspec(dllexport)
#    else
#        define LIBRARY_API __declspec(dllimport)
#    endif
#elif
#    define LIBRARY_API
#endif

When using dllexport/dllimport you do not need to use DEF files, if you use DEF files you do not need to use dllexport/dllimport. The two methods accomplish the same task different ways, I believe that dllexport/dllimport is the recommended method out of the two.

Exporting unmangled functions from a C++ DLL for LoadLibrary/PInvoke

If you need this to use LoadLibrary and GetProcAddress, or maybe importing from another language (i.e PInvoke from .NET, or FFI in Python/R etc) you can use extern "C" inline with your dllexport to tell the C++ compiler not to mangle the names. And since we are using GetProcAddress instead of dllimport we don't need to do the ifdef dance from above, just a simple dllexport:

The Code:

#define EXTERN_DLL_EXPORT extern "C" __declspec(dllexport)

EXTERN_DLL_EXPORT int getEngineVersion() {
  return 1;
}

EXTERN_DLL_EXPORT void registerPlugin(Kernel &K) {
  K.getGraphicsServer().addGraphicsDriver(
    auto_ptr<GraphicsServer::GraphicsDriver>(new OpenGLGraphicsDriver())
  );
}

And here's what the exports look like with Dumpbin /exports:

  Dump of file opengl_plugin.dll

  File Type: DLL

  Section contains the following exports for opengl_plugin.dll

    00000000 characteristics
    49866068 time date stamp Sun Feb 01 19:54:32 2009
        0.00 version
           1 ordinal base
           2 number of functions
           2 number of names

    ordinal hint RVA      name

          1    0 0001110E getEngineVersion = @ILT+265(_getEngineVersion)
          2    1 00011028 registerPlugin = @ILT+35(_registerPlugin)

So this code works fine:

m_hDLL = ::LoadLibrary(T"opengl_plugin.dll");

m_pfnGetEngineVersion = reinterpret_cast<fnGetEngineVersion *>(
  ::GetProcAddress(m_hDLL, "getEngineVersion")
);
m_pfnRegisterPlugin = reinterpret_cast<fnRegisterPlugin *>(
  ::GetProcAddress(m_hDLL, "registerPlugin")
);

You can use below code:

<video width="400" controls autoplay>
    <source src="D:/mov1.mov" type="video/mp4">
</video>

this code will help you.

You can create a custom JSONObjectReuqest and override the getParams method, or you can provide them in the constructor as a JSONObject to be put in the body of the request.

Like this (I edited your code):

JSONObject obj = new JSONObject();
obj.put("id", "1");
obj.put("name", "myname");

RequestQueue queue = MyVolley.getRequestQueue();
JsonObjectRequest jsObjRequest = new JsonObjectRequest(Request.Method.POST,SPHERE_URL,obj,
    new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {
             System.out.println(response);
             hideProgressDialog();
        }
    },
    new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
             hideProgressDialog();
        }
    });
queue.add(jsObjRequest);

var max = db.Users.DefaultIfEmpty().Max(r => r == null ? 0 : r.ModelID);

when there are no records in db it would return 0 with no exception.

You can use the following code for your requirement

map.forEach((k,v)->System.out.println("Item : " + k + " Count : " + v));

ASP.NET Web API is a framework that makes it easy to build HTTP services that reach a broad range of clients, including browsers and mobile devices. ASP.NET Web API is an ideal platform for building RESTful applications on the .NET Framework.

REST

RESTs sweet spot is when you are exposing a public API over the internet to handle CRUD operations on data. REST is focused on accessing named resources through a single consistent interface.

SOAP

SOAP brings it’s own protocol and focuses on exposing pieces of application logic (not data) as services. SOAP exposes operations. SOAP is focused on accessing named operations, each implement some business logic through different interfaces.

Though SOAP is commonly referred to as “web services” this is a misnomer. SOAP has very little if anything to do with the Web. REST provides true “Web services” based on URIs and HTTP.

Reference: http://spf13.com/post/soap-vs-rest

And finally: What they could be referring to is REST vs. RPC See this: http://encosia.com/rest-vs-rpc-in-asp-net-web-api-who-cares-it-does-both/

If anyone is coming here looking for an answer that utilizes iframe here it is

<iframe srcdoc="<html><body>your-html-here</body></html>" />

Is "Module1" part of the same workbook that contains "moduleController"?
If not, you could call public method of "Module1" using Application.Run someWorkbook.xlsm!methodOfModule.

Just try this in Javascript:

 $previous = "javascript:history.go(-1)";

Or you can try it in PHP:

if(isset($_SERVER['HTTP_REFERER'])) {
    $previous = $_SERVER['HTTP_REFERER'];
}

This one is much easie.

Threading.Thread.Sleep(3000)

Another possible fix (solved my problem)

You might have configured the environment properly but for some reason it broke along the way. In this case go to:

file > project settings > modules

Deploy the list of SDKs and look for a red line with [invalid] at the end. If you find one, you have to recreate a python sdk.

It is likely that your previously working SDK is there too, but not red. Delete it.

Now you can click on the new button and add your favorite python virtualenv. And it should work now.

I suggest using phpjs.org 's number_format()

Answering my own question...

libcurl has curl_easy_escape for encoding.

For decoding, curl_easy_unescape

Try LINQPad, it works for SQL Server, MySQL, SQLite and also SDF (SQL CE 4.0). Best of all it's free!

Steps with version 4.35.1:

1. click 'Add Connection'

2. Click Next with 'Build data context automatically' and 'Default(LINQ to SQL)' selected.

3. Under 'Provider' choose 'SQL CE 4.0'.

4. Under 'Database' with 'Attach database file' selected, choose 'Browse' to select your .sdf file.

5. Click 'OK'.

6. Voila! It should show the tables in .sdf and be able to query it via right clicking the table or writing LINQ code in your favorite .NET language or even SQL. How cool is that?

This code will help you to make a result like FEB 17 20:49 .

    String myTimestamp="2014/02/17 20:49";

    SimpleDateFormat form = new SimpleDateFormat("yyyy/MM/dd HH:mm");
    Date date = null;
    Date time = null;
    try 
    {
        date = form.parse(myTimestamp);
        time = new Date(myTimestamp);
        SimpleDateFormat postFormater = new SimpleDateFormat("MMM dd");
        SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");
        String newDateStr = postFormater.format(date).toUpperCase();
        String newTimeStr = sdf.format(time);
        System.out.println("Date  : "+newDateStr);
        System.out.println("Time  : "+newTimeStr);
    }
    catch (Exception e) 
    {
        e.printStackTrace();
    }

Result :

Date : FEB 17

Time : 20:49

You can do exactly the same call with Swift:

Swift 4 & Swift 5

In Swift 4 String is a collection of Character values, it wasn't like this in Swift 2 and 3, so you can use this more concise code¹:

let string = "hello Swift"
if string.contains("Swift") {
    print("exists")
}

Swift 3.0+

var string = "hello Swift"

if string.range(of:"Swift") != nil { 
    print("exists")
}

// alternative: not case sensitive
if string.lowercased().range(of:"swift") != nil {
    print("exists")
}

Older Swift

var string = "hello Swift"

if string.rangeOfString("Swift") != nil{ 
    println("exists")
}

// alternative: not case sensitive
if string.lowercaseString.rangeOfString("swift") != nil {
    println("exists")
}

I hope this is a helpful solution since some people, including me, encountered some strange problems by calling containsString().¹

PS. Don't forget to import Foundation

Footnotes

1. Just remember that using collection functions on Strings has some edge cases which can give you unexpected results, e. g. when dealing with emojis or other grapheme clusters like accented letters.

UPDATE some_table 
   SET this_column=x, that_column=y 
   WHERE something LIKE 'them'

As for now there is no proper solution, as @spro says.

However, if you have an in-flight response and are using ReadableStream, you can close the stream to cancel the request.

fetch('http://example.com').then((res) => {
  const reader = res.body.getReader();

  /*
   * Your code for reading streams goes here
   */

  // To abort/cancel HTTP request...
  reader.cancel();
});

I tried all above but nothing helps, at last i just figured out that under setting >> apps, device still has an entry for uninstalled application as disabled, i just uninstalled from there and it starts working.

Output :

A sort of block comment uses an if statement:

if(FALSE) {
  all your code
}

It works, but I almost always use the block comment options of my editors (RStudio, Kate, Kwrite).

The settings you need are "Local echo" and "Line editing" under the "Terminal" category on the left.

To get the characters to display on the screen as you enter them, set "Local echo" to "Force on".

To get the terminal to not send the command until you press Enter, set "Local line editing" to "Force on".

Explanation:

From the PuTTY User Manual (Found by clicking on the "Help" button in PuTTY):

4.3.8 ‘Local echo’

With local echo disabled, characters you type into the PuTTY window are not echoed in the window by PuTTY. They are simply sent to the server. (The server might choose to echo them back to you; this can't be controlled from the PuTTY control panel.)

Some types of session need local echo, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local echo is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local echo to be turned on, or force it to be turned off, instead of relying on the automatic detection.

4.3.9 ‘Local line editing’ Normally, every character you type into the PuTTY window is sent immediately to the server the moment you type it.

If you enable local line editing, this changes. PuTTY will let you edit a whole line at a time locally, and the line will only be sent to the server when you press Return. If you make a mistake, you can use the Backspace key to correct it before you press Return, and the server will never see the mistake.

Since it is hard to edit a line locally without being able to see it, local line editing is mostly used in conjunction with local echo (section 4.3.8). This makes it ideal for use in raw mode or when connecting to MUDs or talkers. (Although some more advanced MUDs do occasionally turn local line editing on and turn local echo off, in order to accept a password from the user.)

Some types of session need local line editing, and many do not. In its default mode, PuTTY will automatically attempt to deduce whether or not local line editing is appropriate for the session you are working in. If you find it has made the wrong decision, you can use this configuration option to override its choice: you can force local line editing to be turned on, or force it to be turned off, instead of relying on the automatic detection.

Putty sometimes makes wrong choices when "Auto" is enabled for these options because it tries to detect the connection configuration. Applied to serial line, this is a bit trickier to do.

There is a way to skip the errors inside the code and go on with the loop anyway, hope it helps:

Sub new1()

Dim wsFunc As WorksheetFunction: Set wsFunc = Application.WorksheetFunction
Dim ws As Worksheet: Set ws = Sheets(1)
Dim rngLook As Range: Set rngLook = ws.Range("A:M")

currName = "Example"
On Error Resume Next ''if error, the code will go on anyway
cellNum = wsFunc.VLookup(currName, rngLook, 13, 0)

If Err.Number <> 0 Then
''error appeared
    MsgBox "currName not found" ''optional, no need to do anything
End If

On Error GoTo 0 ''no error, coming back to default conditions

End Sub

Either make a Comparator that can compare your objects, or if they are all instances of the same class, you can make that class implement Comparable. You can then use Collections.sort() to do the actual sorting.

There are various ways to achieve this. Here are three.

    Map<String, String> map = new HashMap<String, String>();
    map.put("key1", "value1");
    map.put("key2", "value2");
    map.put("key3", "value3");

    System.out.println("using entrySet and toString");
    for (Entry<String, String> entry : map.entrySet()) {
        System.out.println(entry);
    }
    System.out.println();

    System.out.println("using entrySet and manual string creation");
    for (Entry<String, String> entry : map.entrySet()) {
        System.out.println(entry.getKey() + "=" + entry.getValue());
    }
    System.out.println();

    System.out.println("using keySet");
    for (String key : map.keySet()) {
        System.out.println(key + "=" + map.get(key));
    }
    System.out.println();

Output

using entrySet and toString
key1=value1
key2=value2
key3=value3

using entrySet and manual string creation
key1=value1
key2=value2
key3=value3

using keySet
key1=value1
key2=value2
key3=value3

Here is the code that I am using:

Inside WebViewClient:

               @Override
             public void onPageStarted(WebView view, String url, Bitmap favicon) {

              super.onPageStarted(view, url, favicon);
              findViewById(R.id.progress1).setVisibility(View.VISIBLE);
             }

            @Override
            public void onPageFinished(WebView view, String url) {
                findViewById(R.id.progress1).setVisibility(View.GONE);
            }

Here is the XML :

<ProgressBar
    android:id="@+id/progress1"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

Hope this helps..

Download the Apache Commons Lang and use the method

 StringUtils.join(list)

 StringUtils.join(list, ", ") // 2nd param is the separator.

You can implement it by yourself, of course, but their code is fully tested and is probably the best possible implementation.

I am a big fan of the Apache Commons library and I also think it's a great addition to the Java Standard Library.

In case someone else runs accross this and wants to just disable all path variable changing for all users.
Access your sudoers file by using the command:visudo. You should see the following line somewhere:

Defaults env_reset

which you should add the following on the next line

Defaults !secure_path

secure_path is enabled by default. This option specifies what to make $PATH when sudoing. The exclamation mark disables the feature.

Apache

Does this answer describe or help your situation? Upgrading to Apache 2.4 come with some changes in Apache configuration.

Laravel

Are you checking Laravel's logs or Apache's logs?

Since upgrading to Laravel 4.1, I've had white screen "errors" (WSOD) when the application could not write to the log location. I've always solved this by making the app/storage directory writable by Apache (either group writable to "www-data", "apache" or world-writable - that depends on your server setup.

Web Server User

On Ubuntu/Debian servers, your PHP may be running as user "www-data". On CentOS/RedHat/Fedora servers, you PHP may be running as user "apache".

Make sure your files are owned by the user that is running PHP:

# Debian/Ubuntu
$ sudo chown -R www-data /path/to/laravel/files

# CentOS/RedHat/Fedora
$ sudo chown -R apache /path/to/laravel/files

Note that you might not be running as user www-data or apache. It depends on your hosting and setup!

Laravel 4

# Group Writable (Group, User Writable)
$ sudo chmod -R gu+w app/storage

# World-writable (Group, User, Other Writable)
$ sudo chmod -R guo+w app/storage

Laravel 5+ (including 6)

# Group Writable (Group, User Writable)
$ sudo chmod -R gu+w storage

# World-writable (Group, User, Other Writable)
$ sudo chmod -R guo+w storage

#####
# The bootstrap/cache directory may need writing to also
##

# Group Writable (Group, User Writable)
$ sudo chmod -R gu+w bootstrap/cache

# World-writable (Group, User, Other Writable)
$ sudo chmod -R guo+w bootstrap/cache

I had the same issue when installing the "Twisted" library and solved it by running the following command on Ubuntu 16.04 (Xenial Xerus):

sudo apt-get install python-setuptools python-dev build-essential

Here's a list of languages that can be used to develop on android:

• Java - primary android development language

• Kotlin, language from JetBrains which received first-party support from Google, announced in Google I/O 2017

• C++ - NDK for libraries, not apps

• Python, bash, et. al. - Via the Scripting Environment

• Corona- One is to use the Corona SDK . Corona is a high level SDK built on the Lua programming language. Lua is much simpler to learn than Java and the SDK takes away a lot of the pain in developing Android app.

• Cordova - which uses HTML5, JavaScript, CSS, and can be extended with Java

• Xamarin technology - that uses c# and in which mono is used for that. Here MonoTouch and Mono for Android are cross-platform implementations of the Common Language Infrastructure (CLI) and Common Language Specifications.

As for your second question: android is highly dependent on it's java architecture, I find it unlikely that there will be other primary development languages available any time soon. However, there's no particular reason why someone couldn't implement another language in Java (something like Jython) and use that. However, that surely won't be easier or as performant as just writing the code in Java.

Just loop...

foreach(var table in DataSet1.Tables) {
    foreach(var col in table.Columns) {
       ...
    }
    foreach(var row in table.Rows) {
        object[] values = row.ItemArray;
        ...
    }
}

You might want to use grep "$(echo -e '\t')"

Only requirement is echo to be capable of interpretation of backslash escapes.

WITH CHECK is indeed the default behaviour however it is good practice to include within your coding.

The alternative behaviour is of course to use WITH NOCHECK, so it is good to explicitly define your intentions. This is often used when you are playing with/modifying/switching inline partitions.

This is code in xml of how to center an ImageView, I used "layout_centerHorizontal".

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:layout_centerHorizontal="true"
    >
    <ImageView
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:src="@drawable/img2"
    />
    <ImageView
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:src="@drawable/img1"
        />
</LinearLayout>

or this other example...

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:gravity="center_horizontal"
    >
    <ImageView
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:src="@drawable/img2"
    />
    <ImageView
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:src="@drawable/img1"
        />
</LinearLayout>

This was my final... It gets around all the type issues also:

Here is a simple textbox that requires a number:

   public Sub textbox_memorytotal_TextChanged(sender As Object, e As EventArgs) Handles textbox_memorytotal.TextChanged
        TextboxOnlyNumbers(sender)
    End Sub

and here is the procedure that corrects all bad input:

Public Sub TextboxOnlyNumbers(ByRef objTxtBox As TextBox)

    ' ONLY allow numbers
    If Not IsNumeric(objTxtBox.Text) Then

        ' Don't process things like too many backspaces
        If objTxtBox.Text.Length > 0 Then

            MsgBox("Numerical Values only!")

            Try
                ' If something bad was entered delete the last character
                objTxtBox.Text = objTxtBox.Text.Substring(0, objTxtBox.Text.Length - 1)

                ' Put the cursor and the END of the corrected number
                objTxtBox.Select(objTxtBox.Text.Length + 1, 1)

            Catch ex As Exception
            End Try
        End If
    End If
End Sub

For example, a feature only works for api21 up the following we fix bugs in api21 down

    if(Build.VERSION.SDK_INT >= 21) {
    //only api 21 above
    }else{
   //only api 21 down
    }

The Content-Type header should be set to 'application/json' when posting. Server listening for the request should include "Accept=application/json". In Spring MVC you can do it like this:

@RequestMapping(value="location", method = RequestMethod.POST, headers = "Accept=application/json")

Add headers to the response:

HttpHeaders headers = new HttpHeaders();
headers.add("Content-Type", "application/json");

You can add comments in Vim's configuration file by either:

" brief descriptiion of command

or:

"" commended command

I have a set of 15 subroutines I add to every Coded Excel Workbook I create and this is one of them. The following routine clears the area and creates a border.

Sample Call:

Call BoxIt(Range("A1:z25"))

Subroutine:

Sub BoxIt(aRng As Range)
On Error Resume Next

    With aRng

        'Clear existing
        .Borders.LineStyle = xlNone

        'Apply new borders
        .BorderAround xlContinuous, xlThick, 0
        With .Borders(xlInsideVertical)
            .LineStyle = xlContinuous
            .ColorIndex = 0
            .Weight = xlMedium
        End With
        With .Borders(xlInsideHorizontal)
            .LineStyle = xlContinuous
            .ColorIndex = 0
            .Weight = xlMedium
        End With
    End With

End Sub

Never parallelize an infinite stream with a limit. Here is what happens:

    public static void main(String[] args) {
        // let's count to 1 in parallel
        System.out.println(
            IntStream.iterate(0, i -> i + 1)
                .parallel()
                .skip(1)
                .findFirst()
                .getAsInt());
    }

Result

    Exception in thread "main" java.lang.OutOfMemoryError
        at ...
        at java.base/java.util.stream.IntPipeline.findFirst(IntPipeline.java:528)
        at InfiniteTest.main(InfiniteTest.java:24)
    Caused by: java.lang.OutOfMemoryError: Java heap space
        at java.base/java.util.stream.SpinedBuffer$OfInt.newArray(SpinedBuffer.java:750)
        at ...

Same if you use .limit(...)

Explanation here: Java 8, using .parallel in a stream causes OOM error

Similarly, don't use parallel if the stream is ordered and has much more elements than you want to process, e.g.

public static void main(String[] args) {
    // let's count to 1 in parallel
    System.out.println(
            IntStream.range(1, 1000_000_000)
                    .parallel()
                    .skip(100)
                    .findFirst()
                    .getAsInt());
}

This may run much longer because the parallel threads may work on plenty of number ranges instead of the crucial one 0-100, causing this to take very long time.

Missed property runat="server" or in code use Request.Params["TextArea1"]

Or if you want to check for existence first:

if [[ ! -e /path/to/newdir ]]; then
            mkdir /path/to/newdir
fi

-e is the exist test for KornShell.

You can also try googling a KornShell manual.

You can use event.key

Sadly I can't answer the other questions, don't have enough reputation, but I need to point something out that was VERY important for me, and I think it will help other people too.

Unsetting the variable is a nice way, unless you need the reference of the original array!

To make clear what I mean: If you have a function wich uses the reference of the array, for example a sorting function like

function special_sort_my_array(&$array)
{
    $temporary_list = create_assoziative_special_list_out_of_array($array);

    sort_my_list($temporary_list);

    unset($array);
    foreach($temporary_list as $k => $v)
    {
        $array[$k] = $v;
    }
}

it is not working! Be careful here, unset deletes the reference, so the variable $array is created again and filled correctly, but the values are not accessable from outside the function.

So if you have references, you need to use $array = array() instead of unset, even if it is less clean and understandable.

For the Oracle 12.1 windows client, looking at the output from the TNSPING command seems to work:

For starters:

<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.

This would be the optimal solution:

<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

If 'somescript.py' isn't something you could normally execute directly from the command line (I.e., $: somescript.py works), then you can't call it directly using call.

Remember that the way Popen works is that the first argument is the program that it executes, and the rest are the arguments passed to that program. In this case, the program is actually python, not your script. So the following will work as you expect:

subprocess.call(['python', 'somescript.py', somescript_arg1, somescript_val1,...]).

This correctly calls the Python interpreter and tells it to execute your script with the given arguments.

Note that this is different from the above suggestion:

subprocess.call(['python somescript.py'])

That will try to execute the program called python somscript.py, which clearly doesn't exist.

call('python somescript.py', shell=True)

Will also work, but using strings as input to call is not cross platform, is dangerous if you aren't the one building the string, and should generally be avoided if at all possible.

Believe me or not... I tried out almost each answer I had found here on stackoverflow. Nothing would help, until I just restarted the machine. My Android Studio works on Ubuntu 16.04 LTS.

If you are using rbenv then make sure that you run the "rbenv rehash" command after you set local or global ruby version. It solved the issue for me.

rbenv rehash

if you want to use RecyclerView in NestedScrollView this is a simple tricky, just set :

RecyclerView

• recyclerView.setHasFixedSize(false) (java/kt)

• android:nestedScrollingEnabled="false"

• android:layout_height="wrap_content"

• android:overScrollMode="never"

NestedScrollView

• android:fillViewport="true"

this is work for me, and you can use many RecyclerView in NestedScrollView with this too.

Taking a column is easy with the map function.

// a two-dimensional array
var two_d = [[1,2,3],[4,5,6],[7,8,9]];

// take the third column
var col3 = two_d.map(function(value,index) { return value[2]; });

Why bother with the slice at all? Just filter the matrix to find the rows of interest.

var interesting = two_d.filter(function(value,index) {return value[1]==5;});
// interesting is now [[4,5,6]]

Sadly, filter and map are not natively available on IE9 and lower. The MDN documentation provides implementations for browsers without native support.

Your demo didn't expose memcpy drawbacks because of "bad" compiler, it does you a favor in Debug version. A release version, however, gives you the same output, but because of optimization.

    memcpy(str1 + 2, str1, 4);
00241013  mov         eax,dword ptr [str1 (243018h)]  // load 4 bytes from source string
    printf("New string: %s\n", str1);
00241018  push        offset str1 (243018h) 
0024101D  push        offset string "New string: %s\n" (242104h) 
00241022  mov         dword ptr [str1+2 (24301Ah)],eax  // put 4 bytes to destination
00241027  call        esi  

The register %eax here plays as a temporary storage, which "elegantly" fixes overlap issue.

The drawback emerges when copying 6 bytes, well, at least part of it.

char str1[9] = "aabbccdd";

int main( void )
{
    printf("The string: %s\n", str1);
    memcpy(str1 + 2, str1, 6);
    printf("New string: %s\n", str1);

    strcpy_s(str1, sizeof(str1), "aabbccdd");   // reset string

    printf("The string: %s\n", str1);
    memmove(str1 + 2, str1, 6);
    printf("New string: %s\n", str1);
}

Output:

The string: aabbccdd
New string: aaaabbbb
The string: aabbccdd
New string: aaaabbcc

Looks weird, it's caused by optimization, too.

    memcpy(str1 + 2, str1, 6);
00341013  mov         eax,dword ptr [str1 (343018h)] 
00341018  mov         dword ptr [str1+2 (34301Ah)],eax // put 4 bytes to destination, earlier than the above example
0034101D  mov         cx,word ptr [str1+4 (34301Ch)]  // HA, new register! Holding a word, which is exactly the left 2 bytes (after 4 bytes loaded to %eax)
    printf("New string: %s\n", str1);
00341024  push        offset str1 (343018h) 
00341029  push        offset string "New string: %s\n" (342104h) 
0034102E  mov         word ptr [str1+6 (34301Eh)],cx  // Again, pulling the stored word back from the new register
00341035  call        esi  

This is why I always choose memmove when trying to copy 2 overlapped memory blocks.

If you want to launch VM by sending arguments, you should send VM arguments and not Program arguments.

Program arguments are arguments that are passed to your application, which are accessible via the "args" String array parameter of your main method. VM arguments are arguments such as System properties that are passed to the JavaSW interpreter. The Debug configuration above is essentially equivalent to:

java -DsysProp1=sp1 -DsysProp2=sp2 test.ArgsTest pro1 pro2 pro3

The VM arguments go after the call to your Java interpreter (ie, 'java') and before the Java class. Program arguments go after your Java class.

Consider a program ArgsTest.java:

package test;

import java.io.IOException;

    public class ArgsTest {

        public static void main(String[] args) throws IOException {

            System.out.println("Program Arguments:");
            for (String arg : args) {
                System.out.println("\t" + arg);
            }

            System.out.println("System Properties from VM Arguments");
            String sysProp1 = "sysProp1";
            System.out.println("\tName:" + sysProp1 + ", Value:" + System.getProperty(sysProp1));
            String sysProp2 = "sysProp2";
            System.out.println("\tName:" + sysProp2 + ", Value:" + System.getProperty(sysProp2));

        }
    }

If given input as,

java -DsysProp1=sp1 -DsysProp2=sp2 test.ArgsTest pro1 pro2 pro3 

in the commandline, in project bin folder would give the following result:

Program Arguments:
  pro1
  pro2
  pro3
System Properties from VM Arguments
  Name:sysProp1, Value:sp1
  Name:sysProp2, Value:sp2

Adding this to my connection string worked for me:

Trusted_Connection=true

I agree with Vladimir. The administrators in my company would definitely not appreciate it if I even suggested such a course.

Further, creating an SQL script in stead of blindly trusting Hibernate gives you the opportunity to remove fields which are no longer in use. Hibernate does not do that.

And I find comparing the production schema with the new schema gives you even better insight to wat you changed in the data model. You know, of course, because you made it, but now you see all the changes in one go. Even the ones which make you go like "What the heck?!".

There are tools which can make a schema delta for you, so it isn't even hard work. And then you know exactly what's going to happen.

If you're open to out-of-the-DB solution: You could set up a cron job that runs a script that will itself call the procedure.

Basically, you should add a specific unique field. I usually use xxxUri fields.

class User {

    @Id
    // automatically generated
    private Long id;

    // globally unique id
    @Column(name = "SCN", nullable = false, unique = true)
    private String scn;
}

And you business method will do like this.

public User findUserByScn(@NotNull final String scn) {
    CriteriaBuilder builder = manager.getCriteriaBuilder();
    CriteriaQuery<User> criteria = builder.createQuery(User.class);
    Root<User> from = criteria.from(User.class);
    criteria.select(from);
    criteria.where(builder.equal(from.get(User_.scn), scn));
    TypedQuery<User> typed = manager.createQuery(criteria);
    try {
        return typed.getSingleResult();
    } catch (final NoResultException nre) {
        return null;
    }
}

You need to use join method of Thread object in the end of the script.

t1 = Thread(target=call_script, args=(scriptA + argumentsA))
t2 = Thread(target=call_script, args=(scriptA + argumentsB))
t3 = Thread(target=call_script, args=(scriptA + argumentsC))

t1.start()
t2.start()
t3.start()

t1.join()
t2.join()
t3.join()

Thus the main thread will wait till t1, t2 and t3 finish execution.

One of the best options is to go for MongoDB(NOSql dB) that supports scalability.Stores large amounts of data nothing but bigdata in the form of documents unlike rows and tables in sql.This is fasters that follows sharding of the data.Uses replicasets to ensure data guarantee that maintains multiple servers having primary db server as the base. Language independent. Flexible to use

The method getView() wont work on fragments outside OnCreate and similar methods.

You have two ways, pass the view to the function on the oncreate (what means you can only run your functions when the view is being created) or set the view as a variable:

private View rootView;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
    rootView = inflater.inflate(R.layout.fragment_contatos, container, false);
}

public void doSomething () {
    ImageView thumbnail = (ImageView) rootView.findViewById(R.id.someId);
}

create example script as resp :

#!/bin/bash

http_code=200
mime=text/html

echo -e "HTTP/1.1 $http_code OK\r"
echo "Content-type: $mime"
echo
echo "Set-Cookie: name=F"

then make executable and execute like this.

./resp | nc -l -p 12346

open browser and browse URL: http://localhost:1236 you will see Cookie value which is sent by Browser

    [aaa@bbbbbbbb ]$ ./resp | nc -l -p 12346
    GET / HTTP/1.1
    Host: xxx.xxx.xxx.xxx:12346
    Connection: keep-alive
    Cache-Control: max-age=0
    Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
    Upgrade-Insecure-Requests: 1
    User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.112 Safari/537.36
    Accept-Encoding: gzip, deflate, sdch
    Accept-Language: en-US,en;q=0.8,ru;q=0.6
    Cookie: name=F

This works:

<select name="foo" id="foo">
<option value="1">a</option>
<option value="2">b</option>
<option value="3">c</option>
</select>
<input type="button" id="button" value="Button" />

$('#button').click(function() {
    alert($('#foo option:selected').text());
    alert($('#foo option:selected').val());
});

The usual command line ping tool uses ICMP Echo, but it's true that other protocols can also be used, and they're useful in debugging different kinds of network problems.

I can remember at least arping (for testing ARP requests) and tcping (which tries to establish a TCP connection and immediately closes it, it can be used to check if traffic reaches a certain port on a host) off the top of my head, but I'm sure there are others aswell.

Another solution: This Class delete all files, subdirectories and files in the sub directories.

class Your_Class_Name {
    /**
     * @see http://php.net/manual/de/function.array-map.php
     * @see http://www.php.net/manual/en/function.rmdir.php 
     * @see http://www.php.net/manual/en/function.glob.php
     * @see http://php.net/manual/de/function.unlink.php
     * @param string $path
     */
    public function delete($path) {
        if (is_dir($path)) {
            array_map(function($value) {
                $this->delete($value);
                rmdir($value);
            },glob($path . '/*', GLOB_ONLYDIR));
            array_map('unlink', glob($path."/*"));
        }
    }
}

First, you show that it lies in NP at all.

Then you find another problem that you already know is NP complete and show how you polynomially reduce NP Hard problem to your problem.

If you know you're always going to use bash, it's much easier to always use the double bracket conditional compound command [[ ... ]], instead of the Posix-compatible single bracket version [ ... ]. Inside a [[ ... ]] compound, word-splitting and pathname expansion are not applied to words, so you can rely on

if [[ $aug1 == "and" ]];

to compare the value of $aug1 with the string and.

If you use [ ... ], you always need to remember to double quote variables like this:

if [ "$aug1" = "and" ];

If you don't quote the variable expansion and the variable is undefined or empty, it vanishes from the scene of the crime, leaving only

if [ = "and" ]; 

which is not a valid syntax. (It would also fail with a different error message if $aug1 included white space or shell metacharacters.)

The modern [[ operator has lots of other nice features, including regular expression matching.

Bundler is launched from your app's root directory so it makes sure all needed gems are present to get your app working.If for some reason you no longer need a gem you'll have to run the

    gem uninstall gem_name 

as you stated above.So every time you run bundler it'll recheck dependencies

EDIT - 24.12.2014

I see that people keep coming to this question I decided to add a little something. The answer I gave was for the case when you maintain your gems global. Consider using a gem manager such as rbenv or rvm to keep sets of gems scoped to specific projects.

This means that no gems will be installed at a global level and therefore when you remove one from your project's Gemfile and rerun bundle then it, obviously, won't be loaded in your project. Then, you can run bundle clean (with the project dir) and it will remove from the system all those gems that were once installed from your Gemfile (in the same dir) but at this given time are no longer listed there.... long story short - it removes unused gems.

If you really want to understand ANSI C 89, I need to correct you in one thing; In ANSI C 89 the difference between the following functions:

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

is:

int main()

• a function that expects unknown number of arguments of unknown types. Returns an integer representing the application software status.

int main(void)

• a function that expects no arguments. Returns an integer representing the application software status.

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

• a function that expects argc number of arguments and argv[] arguments. Returns an integer representing the application software status.

About when using each of the functions

int main(void)

• you need to use this function when your program needs no initial parameters to run/ load (parameters received from the OS - out of the program it self).

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

• you need to use this function when your program needs initial parameters to load (parameters received from the OS - out of the program it self).

About void main()

In ANSI C 89, when using void main and compiling the project AS -ansi -pedantic (in Ubuntu, e.g) you will receive a warning indicating that your main function is of type void and not of type int, but you will be able to run the project. Most C developers tend to use int main() on all of its variants, though void main() will also compile.

In my case I solved this issue by uninstalling the version of Arduino that I installed via apt-get and instead installed via the official website.

With the latest version of Arduino I didn't have the problem described on Ubuntu 18.04.

This was just asked a couple of days ago (but I cannot find it):

>>> A = [6, 7, 8, 9, 10, 11, 12]
>>> subset_of_A = set([6, 9, 12])
>>> [i for i in A if i not in subset_of_A]
[7, 8, 10, 11]

It might be better to use sets from the beginning, depending on the context. Then you can use set operations like other answers show.

However, converting lists to sets and back only for these operations is slower than list comprehension.

Checkout this jquery window plugin: http://fstoke.me/jquery/window/

// resize the window by passed w,h parameter
sampleWnd.resize(screen.width, screen.height);

As Wingman said, Google App Engine is a great solution for your scenario.

You can get some information about GAE+Android here: https://developers.google.com/eclipse/docs/appengine_connected_android

And from this Google IO 2012 session: http://www.youtube.com/watch?v=NU_wNR_UUn4

if you get the values in int you have to use string for that it is throwing the error

before

  holder.villageName.setText(villageModelList.get(position).getVillageName());
    holder.villageCount.setText(villageModelList.get(position).getPeopleCount());
    holder.peopleCount.setText(villageModelList.get(position).getPeopleCount());

after

  holder.villageName.setText(villageModelList.get(position).getVillageName());
    holder.villageCount.setText(String.valueOf(villageModelList.get(position).getPeopleCount()));
    holder.peopleCount.setText(String.valueOf(villageModelList.get(position).getPeopleCount()));

you can solve the error by adding the String.valueOf

If you have Boost, you can convert the integer to a string using boost::lexical_cast<std::string>(age).

Another way is to use stringstreams:

std::stringstream ss;
ss << age;
std::cout << name << ss.str() << std::endl;

A third approach would be to use sprintf or snprintf from the C library.

char buffer[128];
snprintf(buffer, sizeof(buffer), "%s%d", name.c_str(), age);
std::cout << buffer << std::endl;

Other posters suggested using itoa. This is NOT a standard function, so your code will not be portable if you use it. There are compilers that don't support it.

"location" : null // this is not really an array it's a null object
"location" : []   // this is an empty array

It looks like this API returns null when there is no location defined - instead of returning an empty array, not too unusual really - but they should tell you if they're going to do this.

Having just done this myself you can do it this way:

from tkinter import Tk, Button, Frame, Entry, END

class ABC(Frame):
    def __init__(self, parent=None):
        Frame.__init__(self, parent)
        self.parent = parent
        self.pack()
        ABC.make_widgets(self)

    def make_widgets(self):
        self.parent.title("Simple Prog")

You will see the title change, and you won't get two windows. I've left my parent as master as in the Tkinter reference stuff in the python library documentation.

3D case

Modifying Mohsen's answer for 3D array:

[M,I] = max (A(:));
[ind1, ind2, ind3] = ind2sub(size(A),I)

in Bash, to source some command's output, instead of a file:

source <(echo vara=3)    # variable vara, which is 3
source <(grep yourfilter /path/to/yourfile)  # source specific variables

reference

Important (in Vue 4 and likely Vue 3+ as well!): I set VUE_APP_VAR but could NOT see it by console logging process and opening the env object. I could see it by logging or referencing process.env.VUE_APP_VAR. I'm not sure why this is but be aware that you have to access the variable directly!

My Answer: All of the following should be overridden (i.e. describe them all within columndefinition, if appropriate):

• length
• precision
• scale
• nullable
• unique

i.e. the column DDL will consist of: name + columndefinition and nothing else.

Rationale follows.

1. Annotation containing the word "Column" or "Table" is purely physical - properties only used to control DDL/DML against database.

2. Other annotation purely logical - properties used in-memory in java to control JPA processing.

3. That's why sometimes it appears the optionality/nullability is set twice - once via @Basic(...,optional=true) and once via @Column(...,nullable=true). Former says attribute/association can be null in the JPA object model (in-memory), at flush time; latter says DB column can be null. Usually you'd want them set the same - but not always, depending on how the DB tables are setup and reused.

In your example, length and nullable properties are overridden and redundant.

So, when specifying columnDefinition, what other properties of @Column are made redundant?

1. In JPA Spec & javadoc:

   • columnDefinition definition: The SQL fragment that is used when generating the DDL for the column.

   • columnDefinition default: Generated SQL to create a column of the inferred type.

   • The following examples are provided:

     @Column(name="DESC", columnDefinition="CLOB NOT NULL", table="EMP_DETAIL")
     @Column(name="EMP_PIC", columnDefinition="BLOB NOT NULL")
     

   • And, err..., that's it really. :-$ ?!

   Does columnDefinition override other properties provided in the same annotation?

   The javadoc and JPA spec don't explicity address this - spec's not giving great protection. To be 100% sure, test with your chosen implementation.

2. The following can be safely implied from examples provided in the JPA spec

   • name & table can be used in conjunction with columnDefinition, neither are overridden
   • nullable is overridden/made redundant by columnDefinition

3. The following can be fairly safely implied from the "logic of the situation" (did I just say that?? :-P ):

   • length, precision, scale are overridden/made redundant by the columnDefinition - they are integral to the type
   • insertable and updateable are provided separately and never included in columnDefinition, because they control SQL generation in-memory, before it is emmitted to the database.

4. That leaves just the "unique" property. It's similar to nullable - extends/qualifies the type definition, so should be treated integral to type definition. i.e. should be overridden.

Test My Answer For columns "A" & "B", respectively:

  @Column(name="...", table="...", insertable=true, updateable=false,
          columndefinition="NUMBER(5,2) NOT NULL UNIQUE"

  @Column(name="...", table="...", insertable=false, updateable=true,
          columndefinition="NVARCHAR2(100) NULL"

• confirm generated table has correct type/nullability/uniqueness
• optionally, do JPA insert & update: former should include column A, latter column B

I believe passing -Wno-write-strings to gcc will suppress this warning.

I hit this question looking for how to run batch scripts during user logon on a standalone windows server (workgroup not in domain). I found the answer in using group policy.

1. gpedit.msc
2. user configuration->administrative templates->system->logon->run these programs at user logon
3. add batch scripts.
4. you can add them using cmd /k mybatchfile.cmd if you want the command window to stay (on desktop) after batch script have finished.
5. gpupdate - to update the group policy.

This works for me:

window.onload = function() {
    // short timeout
    setTimeout(function() {
        $(document.body).scrollTop(0);
    }, 15);
};

Uses a short setTimeout inside the onload to give the browser a chance to do the scroll.

Just open the file with the FileMode.Truncate flag, then close it:

using (var fs = new FileStream(@"C:\path\to\file", FileMode.Truncate))
{
}

Another alternative is to use capturing sub-expressions with the regular expression functions regmatches and regexec.

# the original example
x <- 'hello stackoverflow'

# grab the substrings
myStrings <- regmatches(x, regexec('(^.)(.*)', x))

This returns the entire string, the first character, and the "popped" result in a list of length 1.

myStrings
[[1]]
[1] "hello stackoverflow" "h"                   "ello stackoverflow" 

which is equivalent to list(c(x, substr(x, 1, 1), substr(x, 2, nchar(x)))). That is, it contains the super set of the desired elements as well as the full string.

Adding sapply will allow this method to work for a character vector of length > 1.

# a slightly more interesting example
xx <- c('hello stackoverflow', 'right back', 'at yah')

# grab the substrings
myStrings <- regmatches(x, regexec('(^.)(.*)', xx))

This returns a list with the matched full string as the first element and the matching subexpressions captured by () as the following elements. So in the regular expression '(^.)(.*)', (^.) matches the first character and (.*) matches the remaining characters.

myStrings
[[1]]
[1] "hello stackoverflow" "h"                   "ello stackoverflow" 

[[2]]
[1] "right back" "r"          "ight back" 

[[3]]
[1] "at yah" "a"      "t yah" 

Now, we can use the trusty sapply + [ method to pull out the desired substrings.

myFirstStrings <- sapply(myStrings, "[", 2)
myFirstStrings
[1] "h" "r" "a"
mySecondStrings <- sapply(myStrings, "[", 3)
mySecondStrings
[1] "ello stackoverflow" "ight back"          "t yah"

How about:

public class test {
    public static void someFunction(String[] strArray) { 
        // do something 
    }

    public static void main(String[] args) {
        String[] strArray = new String[]{"Foo","Bar","Baz"};
        someFunction(strArray);
    }
}

Instance methods need to be called from an instance. Your setLoanItem method is an instance method (it doesn't have the modifier static), which it needs to be in order to function (because it is setting a value on the instance that it's called on (this)).

You need to create an instance of the class before you can call the method on it:

Media media = new Media();
media.setLoanItem("Yes");

(Btw it would be better to use a boolean instead of a string containing "Yes".)

I don't know if you resolved your problem, but a simple way to resolve this is rebuilding the DataSource (it is a property) of your datagridview. For example:

grdPatient.DataSource = MethodThatReturnList();

So, in that MethodThatReturnList() you can build a List (List is a class) with all the items you need. In my case, I have a method that return the values for two columns that I have on my datagridview.

Pasch.

detach(package:PackageName) works and there is no need to use quotes.

You hide Bootstrap modals with:

$('#modal').modal('hide');

Saying $().hide() makes the matched element invisible, but as far as the modal-related code is concerned, it's still there. See the Methods section in the Modals documentation.
