For books, I would recommend Design Patterns Explained, and Head First Design patterns. To really learn these patterns, you should look at your existing code. Look for what patterns you are already using. Look at code smells and what patterns might solve them.

As a similar approach to the accepted answer that might be considered a bit more readable, elegant, and general (YMMV), you can leverage the map method:

# OP example
df['var3'].map(lambda n: '{:,.2%}'.format(n))

# also works on a series
series_example.map(lambda n: '{:,.2%}'.format(n))

Performance-wise, this is pretty close (marginally slower) than the OP solution.

As an aside, if you do choose to go the pd.options.display.float_format route, consider using a context manager to handle state per this parallel numpy example.

The dropdown-submenu has been removed in Bootstrap 3 RC. In the words of Bootstrap author Mark Otto..

"Submenus just don't have much of a place on the web right now, especially the mobile web. They will be removed with 3.0" - https://github.com/twbs/bootstrap/pull/6342

But, with a little extra CSS you can get the same functionality.

Bootstrap 4 (navbar submenu on hover)

.navbar-nav li:hover > ul.dropdown-menu {
    display: block;
}
.dropdown-submenu {
    position:relative;
}
.dropdown-submenu>.dropdown-menu {
    top:0;
    left:100%;
    margin-top:-6px;
}

Navbar submenu dropdown hover
Navbar submenu dropdown hover (right aligned)
Navbar submenu dropdown click (right aligned)
Navbar dropdown hover (no submenu)

Bootstrap 3

Here is an example that uses 3.0 RC 1: http://bootply.com/71520

Here is an example that uses Bootstrap 3.0.0 (final): http://bootply.com/86684

I had this error on a number of modules when I had been running different versions of PHP side by side on my server. To sort this out, I needed to install the packages it couldn't find for that specific PHP version. So, for example, if I saw:-

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/20160303/xml.so'

I would install the library for the PHP version specifically:-

sudo apt-get install php7.1-xml

And then restart Apache. Fixed it for me. You can check your version like this:-

php -v

You have to bind the resize event on the window object, not on a generic html element.

You could then use this:

$(window).resize(function() {
    ...
});

and within the callback function you can check the new width of your div calling

$('.a-selector').width();

So, the answer to your question is no, you can't bind the resize event to a div.

You can use link-rewriting to append a unique identifier to all your URLs when starting at a single page (e.g. index.html/jsp/whatever). The browser will use the same cookies for all your tabs so everything you put in cookies will not be unique.

Can you define further processing?

You can use a for loop to almost do this, but there's no easy way to insert CR/LF into an environment variable, so you'll have everything in one line. (you may be able to work around this depending on what you need to do.)

You're also limited to less than about 8k text files this way. (You can't create a single env var bigger than around 8k.)

Bill's suggestion of a for loop is probably what you need. You process the file one line at a time:

(use %i at a command line %%i in a batch file)

for /f "tokens=1 delims=" %%i in (file.txt) do echo %%i

more advanced:

for /f "tokens=1 delims=" %%i in (file.txt) do call :part2 %%i
goto :fin

:part2
echo %1
::do further processing here
goto :eof

:fin

This worked fine for me:

else if(requestCode == GALLERY_ACTIVITY_NEW && resultCode == Activity.RESULT_OK)
{
    Uri uri = data.getData();
    Log.i(TAG, "old uri =  " + uri);
    dumpImageMetaData(uri);

    try {
        ParcelFileDescriptor parcelFileDescriptor =
                getContentResolver().openFileDescriptor(uri, "r");
        FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
        Log.i(TAG, "File descriptor " + fileDescriptor.toString());

        final BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFileDescriptor(fileDescriptor, null, options);

        options.inSampleSize =
           BitmapHelper.calculateInSampleSize(options,
                                              User.PICTURE_MAX_WIDTH_IN_PIXELS,
                                              User.PICTURE_MAX_HEIGHT_IN_PIXELS);
        options.inJustDecodeBounds = false;

        Bitmap bitmap = BitmapFactory.decodeFileDescriptor(fileDescriptor, null, options);
        imageViewPic.setImageBitmap(bitmap);

        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
        // get byte array here
        byte[] picData = stream.toByteArray();
        ParseFile picFile = new ParseFile(picData);
        user.setProfilePicture(picFile);
    }
    catch(FileNotFoundException exc)
    {
        Log.i(TAG, "File not found: " + exc.toString());
    }
}

Old Q, but for posterity...it also also happens (.NET Core 2.1) if you have a self-referencing navigation property ("Parent" or "Children" of the same type) but the Id property name isn't what EF expects. That is, I had an "Id" property on my class called WorkflowBase, and it had an array of related child steps, which were also of type WorkflowBase, and it kept trying to associate them with a non-existent "WorkflowBaseId" (the name i suppose it prefers as a natural/conventional default). I had to explicitly configure it using HasMany(), WithOne(), and HasConstraintName() to tell it how to traverse. But I spent a few hours thinking the problem was in 'locally' mapping the object's primary key, which i attempted to fix a bunch of different ways but which was probably always working.

Try this:

console.dir(myObject,{depth:null})

Have hit the same problem today.

These are poorly documented, an open issue exist.

Some for keyup, like space:

<input (keyup.space)="doSomething()">
<input (keyup.spacebar)="doSomething()">  

Some for keydown
(may work for keyup too):

<input (keydown.enter)="...">
<input (keydown.a)="...">
<input (keydown.esc)="...">
<input (keydown.alt)="...">
<input (keydown.shift.esc)="...">
<input (keydown.shift.arrowdown)="...">
<input (keydown.f4)="...">

All above are from below links:

https://github.com/angular/angular/issues/18870
https://github.com/angular/angular/issues/8273
https://github.com/angular/angular/blob/master/packages/platform-browser/src/dom/events/key_events.ts
https://alligator.io/angular/binding-keyup-keydown-events/

The following code will fail:

List<String> will_fail =  (List<String>)Collections.unmodifiableCollection(new ArrayList<String>());

This instead will work:

List<String> will_work = new ArrayList<String>(Collections.unmodifiableCollection(new ArrayList<String>()));

In case you need to check against any amount of whitespace, not just single space, you can do this:

To strip string of extra white space (also condences whitespace in the middle to one space):

trimmed=`echo -- $original`

The -- ensures that if $original contains switches understood by echo, they'll still be considered as normal arguments to be echoed. Also it's important to not put "" around $original, or the spaces will not get removed.

After that you can just check if $trimmed is empty.

[ -z "$trimmed" ] && echo "empty!"

Specifically...

How and where is app.run() used? After module definition or after app.config(), after app.controller()?

Where:

In your package.js E.g. /packages/dashboard/public/controllers/dashboard.js

How:

Make it look like this

var app = angular.module('mean.dashboard', ['ui.bootstrap']);

app.controller('DashboardController', ['$scope', 'Global', 'Dashboard',
    function($scope, Global, Dashboard) {
        $scope.global = Global;
        $scope.package = {
            name: 'dashboard'
        };
        // ...
    }
]);

app.run(function(editableOptions) {
    editableOptions.theme = 'bs3'; // bootstrap3 theme. Can be also 'bs2', 'default'
});

If anybody is looking for complete circular button than I achieved it this way.

Center(
            child: SizedBox.fromSize(
              size: Size(80, 80), // button width and height
              child: ClipOval(
                child: Material(
                  color: Colors.pink[300], // button color
                  child: InkWell(
                    splashColor: Colors.yellow, // splash color
                    onTap: () {}, // button pressed
                    child: Column(
                      mainAxisAlignment: MainAxisAlignment.center,
                      children: <Widget>[
                        Icon(Icons.linked_camera), // icon
                        Text("Picture"), // text
                      ],
                    ),
                  ),
                ),
              ),
            ),
          )

In a comment you wrote

i want to show that there is a difference in local and github repo

As already mentioned in another answer, you should do a git fetch origin first. Then, if the remote is ahead of your current branch, you can list all commits between your local branch and the remote with

git log master..origin/master --stat

If your local branch is ahead:

git log origin/master..master --stat

--stat shows a list of changed files as well.

If you want to explicitly list the additions and deletions, use git diff:

git diff master origin/master

Please check this out below sample code for semaphore implementation(Lock and unlock).

            key=ftok(".",'a');
            if(key == -1 ) {
                    printf("\n\n Initialization Falied of shared memory \n\n");
                    return 1;

            }
            return 0;

I use a List of NameValuePair and URLEncodedUtils to create the url string I want.

protected String addLocationToUrl(String url){
    if(!url.endsWith("?"))
        url += "?";

    List<NameValuePair> params = new LinkedList<NameValuePair>();

    if (lat != 0.0 && lon != 0.0){
        params.add(new BasicNameValuePair("lat", String.valueOf(lat)));
        params.add(new BasicNameValuePair("lon", String.valueOf(lon)));
    }

    if (address != null && address.getPostalCode() != null)
        params.add(new BasicNameValuePair("postalCode", address.getPostalCode()));
    if (address != null && address.getCountryCode() != null)
        params.add(new BasicNameValuePair("country",address.getCountryCode()));

    params.add(new BasicNameValuePair("user", agent.uniqueId));

    String paramString = URLEncodedUtils.format(params, "utf-8");

    url += paramString;
    return url;
}

Other answers already covered other options, but I prefer this one:

s = `${n}`

Short, succinct, already used in many other places (if you're using a modern framework / ES version) so it's a safe bet any programmer will understand it.

Not that it (usually) matters much, but it also seems to be among the fastest compared to other methods.

This happens because $cOTLdata is not null but the index 'char_data' does not exist. Previous versions of PHP may have been less strict on such mistakes and silently swallowed the error / notice while 7.4 does not do this anymore.

To check whether the index exists or not you can use isset():

isset($cOTLdata['char_data'])

Which means the line should look something like this:

$len = isset($cOTLdata['char_data']) ? count($cOTLdata['char_data']) : 0;

Note I switched the then and else cases of the ternary operator since === null is essentially what isset already does (but in the positive case).

To convert the string to an actual dict, you can do df['Pollutant Levels'].map(eval). Afterwards, the solution below can be used to convert the dict to different columns.

Using a small example, you can use .apply(pd.Series):

In [2]: df = pd.DataFrame({'a':[1,2,3], 'b':[{'c':1}, {'d':3}, {'c':5, 'd':6}]})

In [3]: df
Out[3]:
   a                   b
0  1           {u'c': 1}
1  2           {u'd': 3}
2  3  {u'c': 5, u'd': 6}

In [4]: df['b'].apply(pd.Series)
Out[4]:
     c    d
0  1.0  NaN
1  NaN  3.0
2  5.0  6.0

To combine it with the rest of the dataframe, you can concat the other columns with the above result:

In [7]: pd.concat([df.drop(['b'], axis=1), df['b'].apply(pd.Series)], axis=1)
Out[7]:
   a    c    d
0  1  1.0  NaN
1  2  NaN  3.0
2  3  5.0  6.0

Using your code, this also works if I leave out the iloc part:

In [15]: pd.concat([df.drop('b', axis=1), pd.DataFrame(df['b'].tolist())], axis=1)
Out[15]:
   a    c    d
0  1  1.0  NaN
1  2  NaN  3.0
2  3  5.0  6.0

For MySql take in mind that it's not a good idea to write camelcase. For example if the schema is like that:

CREATE TABLE IF NOT EXISTS `task`(
    `id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
    `teaching_hours` DECIMAL(5,2) DEFAULT NULL,
    `isActive` BOOLEAN DEFAULT FALSE,
    `is_validated` BOOLEAN DEFAULT FALSE,
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

You must be very careful cause isActive column will translate to isactive. So in your Entity class is should be like this:

 @Basic
 @Column(name = "isactive", nullable = true)
 public boolean isActive() {
     return isActive;
 }
 public void setActive(boolean active) {
     isActive = active;
 }

That was my problem at least that got me your error

This has nothing to do with MySql which is case insensitive, but rather is a naming strategy that spring will use to translate your tables. For more refer to this post

You need to set Transaction for every Account.

foreach(Account account : accounts){
    account.setTransaction(transactionObj);
}

Or it colud be enough (if appropriate) to set ids to null on many side.

// list of existing accounts
List<Account> accounts = new ArrayList<>(transactionObj.getAccounts());

foreach(Account account : accounts){
    account.setId(null);
}

transactionObj.setAccounts(accounts);

// just persist transactionObj using EntityManager merge() method.

You can compare the returned value of fp.tell() before and after calling the read method. If they return the same value, fp is at eof.

Furthermore, I don't think your example code actually works. The read method to my knowledge never returns None, but it does return an empty string on eof.

You can remove the duplicate elements with the uniq method:

array.uniq  # => [1, 2, 4, 5, 6, 7, 8]

What might also be useful to know is that uniq takes a block, so if you have a have an array of keys:

["bucket1:file1", "bucket2:file1", "bucket3:file2", "bucket4:file2"]

and you want to know what the unique files are, you can find it out with:

a.uniq { |f| f[/\d+$/] }.map { |p| p.split(':').last }

A more informative question is what makes code not thread safe- and the answer is that there are four conditions that must be true... Imagine the following code (and it's machine language translation)

totalRequests = totalRequests + 1
MOV EAX, [totalRequests]   // load memory for tot Requests into register
INC EAX                    // update register
MOV [totalRequests], EAX   // store updated value back to memory

1. The first condition is that there are memory locations that are accessible from more than one thread. Typically, these locations are global/static variables or are heap memory reachable from global/static variables. Each thread gets it's own stack frame for function/method scoped local variables, so these local function/method variables, otoh, (which are on the stack) are accessible only from the one thread that owns that stack.
2. The second condition is that there is a property (often called an invariant), which is associated with these shared memory locations, that must be true, or valid, for the program to function correctly. In the above example, the property is that “totalRequests must accurately represent the total number of times any thread has executed any part of the increment statement”. Typically, this invariant property needs to hold true (in this case, totalRequests must hold an accurate count) before an update occurs for the update to be correct.
3. The third condition is that the invariant property does NOT hold during some part of the actual update. (It is transiently invalid or false during some portion of the processing). In this particular case, from the time totalRequests is fetched until the time the updated value is stored, totalRequests does not satisfy the invariant.
4. The fourth and final condition that must occur for a race to happen (and for the code to therefore NOT be "thread-safe") is that another thread must be able to access the shared memory while the invariant is broken, thereby causing inconsistent or incorrect behavior.

If you still use OID, it would be better to remove the dependency on it, because in recent versions of Postgres it is no longer supported. This can stop (temporarily until you solve it) your migration from version 10 to 12 for example.

See also: https://dev.to/rafaelbernard/postgresql-pgupgrade-from-10-to-12-566i

You can use this to replace the function if it doesn't exist:

<script>
if (!Array.prototype.indexOf) {
    Array.prototype.indexOf = function(elt /*, from*/) {
        var len = this.length >>> 0;

        var from = Number(arguments[1]) || 0;
        from = (from < 0) ? Math.ceil(from) : Math.floor(from);
        if (from < 0)
            from += len;

        for (; from < len; from++) {
            if (from in this && this[from] === elt)
                return from;

Well I've got exactly the same problem with size recalculation and after hours of headache I have to disagree with .append() behaving strictly synchronous. Well at least in Google Chrome. See following code.

var input = $( '<input />' );
input.append( arbitraryElement );
input.css( 'padding-left' );

The padding-left property is correctly retrieved in Firefox but it is empty in Chrome. Like all other CSS properties I suppose. After some experiments I had to settle for wrapping the CSS 'getter' into setTimeout() with 10 ms delay which I know is UGLY as hell but the only one working in Chrome. If any of you had an idea how to solve this issue better way I'd be very grateful.

Issue the following command to reseed mytable to start at 1:

DBCC CHECKIDENT (mytable, RESEED, 0)

Read about it in the Books on Line (BOL, SQL help). Also be careful that you don't have records higher than the seed you are setting.

Install opencv-python (which is an unofficial pre-built OpenCV package for Python) by issuing the following command:

pip install opencv-python

The first value is the precision and the second is the scale, so 18,0 is essentially 18 digits with 0 digits after the decimal place. If you had 18,2 for example, you would have 18 digits, two of which would come after the decimal...

example of 18,2: 1234567890123456.12

There is no functional difference between numeric and decimal, other that the name and I think I recall that numeric came first, as in an earlier version.

And to answer, "can I add (-10) in that column?" - Yes, you can.

Here are some options for using AJAX to upload files:

• AjaxFileUpload - Requires a form element on the page, but uploads the file without reloading the page. See the Demo.

• List of JQuery Plug-ins Tagged With "File"

• Uploadify - A Flash-based method of uploading files.

• How can I upload files asynchronously?

• Ten Examples of AJAX File Upload - This was posted this year.

UPDATE: Here is a JQuery plug-in for Multiple File Uploading.

Strictly stated you must check all of the following: defined, not empty AND not None.

For "normal" variables it makes a difference if defined and set or not set. See foo and bar in the example below. Both are defined but only foo is set.

On the other side registered variables are set to the result of the running command and vary from module to module. They are mostly json structures. You probably must check the subelement you're interested in. See xyz and xyz.msg in the example below:

cat > test.yml <<EOF
- hosts: 127.0.0.1

  vars:
    foo: ""          # foo is defined and foo == '' and foo != None
    bar:             # bar is defined and bar != '' and bar == None

  tasks:

  - debug:
      msg : ""
    register: xyz    # xyz is defined and xyz != '' and xyz != None
                     # xyz.msg is defined and xyz.msg == '' and xyz.msg != None

  - debug:
      msg: "foo is defined and foo == '' and foo != None"
    when: foo is defined and foo == '' and foo != None

  - debug:
      msg: "bar is defined and bar != '' and bar == None"
    when: bar is defined and bar != '' and bar == None

  - debug:
      msg: "xyz is defined and xyz != '' and xyz != None"
    when: xyz is defined and xyz != '' and xyz != None
  - debug:
      msg: "{{ xyz }}"

  - debug:
      msg: "xyz.msg is defined and xyz.msg == '' and xyz.msg != None"
    when: xyz.msg is defined and xyz.msg == '' and xyz.msg != None
  - debug:
      msg: "{{ xyz.msg }}"
EOF

I think this drop shadow value is good for most cases:

<solid android:color="#20000000" />

I am using following code for create excel 2007 file which create the file and write in that file but when i open the file but it give me error that exel cannot open the file bcz file might be coruupted or extension of the file is not compatible. but if i used .xls for file it work fines

for (int i = 0; i < TotalFile; i++)
{
    Contact.Clear();
    if (innerloop == SplitSize)

You can use tandem of MemoryStream and StreamReader classes:

void Main()
{
    string myString;

    using (var stream = new MemoryStream())
    {
        Print(stream);

        stream.Position = 0;
        using (var reader = new StreamReader(stream))
        {
            myString = reader.ReadToEnd();
        }
    }
}

Also, we can assign the Value to the Control in Designer Class (i.e. FormName.Designer.cs).

DateTimePicker1.Value = DateTime.Now;

This way you always get Current Date...

To rename a table you can use:

RENAME mytable TO othertable;

or

ALTER TABLE mytable RENAME TO othertable;

or, if owned by another schema:

ALTER TABLE owner.mytable RENAME TO othertable;

Interestingly, ALTER VIEW does not support renaming a view. You can, however:

RENAME myview TO otherview;

The RENAME command works for tables, views, sequences and private synonyms, for your own schema only.

If the view is not in your schema, you can recompile the view with the new name and then drop the old view.

(tested in Oracle 10g)

This is working for me -

SELECT DATEDIFF(DAY, startdate, enddate) AS DayCount

Example : SELECT DATEDIFF(DAY, '11/30/2019', GETDATE()) AS DayCount

I did have the same problem and at first I added:

<activity
    android:name="com.companyname.applicationname"
    android:windowSoftInputMode="adjustPan">

to my manifest file. But this alone did not solve the issue. Then as mentioned by Artem Russakovskii, I added:

<ScrollView
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:isScrollContainer="false">
</ScrollView>

in the scrollview.

This is what worked for me.

Just for fun:

var mystring = "this,is,a,test"  
var newchar = '|'
mystring = mystring.split(',').join(newchar);

use try-catch to see real error occurred on you

 try
{
  //Your insert code here
}
catch (System.Data.SqlClient.SqlException sqlException)
{
  System.Windows.Forms.MessageBox.Show(sqlException.Message);
}

I have stumbled here twice, and this last time was a unique situation and even though I ditch using copy-item I wanted to post the solution I used.

Had a list of nothing but files with the full path and in majority of the case the files have no extensions. the -Recurse -Force option would not work for me so I ditched copy-item function and fell back to something like below using xcopy as I still wanted to keep it a one liner. Initially I tied with Robocopy but it is apparently looking for a file extension and since many of mine had no extension it considered it a directory.

$filelist = @("C:\Somepath\test\location\here\file","C:\Somepath\test\location\here2\file2")

$filelist | % { echo f | xcopy $_  $($_.Replace("somepath", "somepath_NEW")) }

Hope it helps someone.

If you just want to check the type, you can use jQuery's .is() function,

Like in my case I used below,

if($("#id").is("select")) {
 alert('Select'); 
else if($("#id").is("input")) {
 alert("input");
}

Thanks to Lincoln's comment below, I've changed this answer.

The following answer properly handles 8-bit ints at compile time. It doees, however, require C++17. If you don't have C++17, you'll have to do something else (e.g. provide overloads of this function, one for uint8_t and one for int8_t, or use something besides "if constexpr", maybe enable_if).

template< typename T >
std::string int_to_hex( T i )
{
    // Ensure this function is called with a template parameter that makes sense. Note: static_assert is only available in C++11 and higher.
    static_assert(std::is_integral<T>::value, "Template argument 'T' must be a fundamental integer type (e.g. int, short, etc..).");

    std::stringstream stream;
    stream << "0x" << std::setfill ('0') << std::setw(sizeof(T)*2) << std::hex;

    // If T is an 8-bit integer type (e.g. uint8_t or int8_t) it will be 
    // treated as an ASCII code, giving the wrong result. So we use C++17's
    // "if constexpr" to have the compiler decides at compile-time if it's 
    // converting an 8-bit int or not.
    if constexpr (std::is_same_v<std::uint8_t, T>)
    {        
        // Unsigned 8-bit unsigned int type. Cast to int (thanks Lincoln) to 
        // avoid ASCII code interpretation of the int. The number of hex digits 
        // in the  returned string will still be two, which is correct for 8 bits, 
        // because of the 'sizeof(T)' above.
        stream << static_cast<int>(i);
    }        
    else if (std::is_same_v<std::int8_t, T>)
    {
        // For 8-bit signed int, same as above, except we must first cast to unsigned 
        // int, because values above 127d (0x7f) in the int will cause further issues.
        // if we cast directly to int.
        stream << static_cast<int>(static_cast<uint8_t>(i));
    }
    else
    {
        // No cast needed for ints wider than 8 bits.
        stream << i;
    }

    return stream.str();
}

Original answer that doesn't handle 8-bit ints correctly as I thought it did:

Kornel Kisielewicz's answer is great. But a slight addition helps catch cases where you're calling this function with template arguments that don't make sense (e.g. float) or that would result in messy compiler errors (e.g. user-defined type).

template< typename T >
std::string int_to_hex( T i )
{
  // Ensure this function is called with a template parameter that makes sense. Note: static_assert is only available in C++11 and higher.
  static_assert(std::is_integral<T>::value, "Template argument 'T' must be a fundamental integer type (e.g. int, short, etc..).");

  std::stringstream stream;
  stream << "0x" 
         << std::setfill ('0') << std::setw(sizeof(T)*2) 
         << std::hex << i;

         // Optional: replace above line with this to handle 8-bit integers.
         // << std::hex << std::to_string(i);

  return stream.str();
}

I've edited this to add a call to std::to_string because 8-bit integer types (e.g. std::uint8_t values passed) to std::stringstream are treated as char, which doesn't give you the result you want. Passing such integers to std::to_string handles them correctly and doesn't hurt things when using other, larger integer types. Of course you may possibly suffer a slight performance hit in these cases since the std::to_string call is unnecessary.

Note: I would have just added this in a comment to the original answer, but I don't have the rep to comment.

I had a similar problem with height except my chart was inside a bootstrap modal popup, which I'm already controlling the size of with css. However, for some reason when the window was resized horizontally the height of the chart container would expand indefinitely. If you were to drag the window back and forth it would expand vertically indefinitely. I also don't like hard-coded height/width solutions.

So, if you're doing this in a modal, combine this solution with a window resize event.

// from link
$('#ChartModal').on('show.bs.modal', function() {
    $('.chart-container').css('visibility', 'hidden');
});

$('#ChartModal').on('shown.bs.modal.', function() {
    $('.chart-container').css('visibility', 'initial');
    $('#chartbox').highcharts().reflow()
    //added
    ratio = $('.chart-container').width() / $('.chart-container').height();
});

Where "ratio" becomes a height/width aspect ratio, that will you resize when the bootstrap modal resizes. This measurement is only taken when he modal is opened. I'm storing ratio as a global but that's probably not best practice.

$(window).on('resize', function() {
    //chart-container is only visible when the modal is visible.
    if ( $('.chart-container').is(':visible') ) {
        $('#chartbox').highcharts().setSize( 
            $('.chart-container').width(),
            ($('.chart-container').width() / ratio),
            doAnimation = true );
    }       
});

So with this, you can drag your screen to the side (resizing it) and your chart will maintain its aspect ratio.

Widescreen

vs smaller

(still fiddling around with vw units, so everything in the back is too small to read lol!)

shell_exec - Execute command via shell and return the complete output as a string

exec - Execute an external program.

The difference is that with shell_exec you get output as a return value.

One line solution:

   [ -f ./myfile ] && echo exists

One line solution with error action:

   [ -f ./myfile ] && echo exists || echo not exists

Example used in my make clean directives:

clean:
    @[ -f ./myfile ] && rm myfile || true

And make clean works without error messages!

A shorter solution (which doesn't force you to repeat the vector name 4 times) would be to use Boost:

#include <boost/range/algorithm_ext/erase.hpp>

// ...

boost::remove_erase(vec, int_to_remove);

See http://www.boost.org/doc/libs/1_64_0/libs/range/doc/html/range/reference/algorithms/new/remove_erase.html

You can combine the two functions; coerce to characters thence to numerics:

> fac <- factor(c("1","2","1","2"))
> as.numeric(as.character(fac))
[1] 1 2 1 2

Do you want to find the length of the string in python language ? If you want to find the length of the word, you can use the len function.

string = input("Enter the string : ")

print("The string length is : ",len(string))

OUTPUT : -

Enter the string : viral

The string length is : 5

Usage:

sftp("file:/C:/home/file.txt", "ssh://user:pass@host/home");
sftp("ssh://user:pass@host/home/file.txt", "file:/C:/home");

Implementation

You have to define your TASK_CAT column first and then set foreign key on it.

private static final String TASK_TABLE_CREATE = "create table "
        + TASK_TABLE + " (" 
        + TASK_ID + " integer primary key autoincrement, " 
        + TASK_TITLE + " text not null, " 
        + TASK_NOTES + " text not null, "
        + TASK_DATE_TIME + " text not null,"
        + TASK_CAT + " integer,"
        + " FOREIGN KEY ("+TASK_CAT+") REFERENCES "+CAT_TABLE+"("+CAT_ID+"));";

More information you can find on sqlite foreign keys doc.

You will get default location if user database by this query:

declare @DataFileName nVarchar(500)

declare @LogFileName   nVarchar(500)


set @DataFileName = (select top 1 RTRIM(LTRIM(name)) FROM master.sys.master_files where database_id >4 AND file_id = 1)+'.mdf'
set @LogFileName =   (select top 1 RTRIM(LTRIM(name)) FROM master.sys.master_files where database_id >4 AND file_id = 2)+'.ldf'

select  
( SELECT top 1 SUBSTRING(physical_name, 1, CHARINDEX(@DataFileName, LOWER(physical_name)) - 1) 
FROM master.sys.master_files
WHERE database_id >4 AND file_id = 1) as 'Data File'
,

(SELECT top 1 SUBSTRING(physical_name, 1, CHARINDEX(@LogFileName, LOWER(physical_name)) - 1)
FROM master.sys.master_files
WHERE database_id >4 AND file_id = 2)  as 'Log File'

HTML5 ARIA attribute is what you're looking for. It can be used in your code even without bootstrap.

Accessible Rich Internet Applications (ARIA) defines ways to make Web content and Web applications (especially those developed with Ajax and JavaScript) more accessible to people with disabilities.

To be precise for your question, here is what your attributes are called as ARIA attribute states and model

aria-labelledby: Identifies the element (or elements) that labels the current element.

aria-hidden (state): Indicates that the element and all of its descendants are not visible or perceivable to any user as implemented by the author.

I found that this works really well in Chrome.

Right click on the element that you'd like to inspect, then click Force Element State > Hover. Screenshot attached.

It looks like ByRef needs to know the size of the parameter. A declaration of Dim last_name as string doesn't specify the size of the string so it takes it as an error. Before using Worksheets(data_sheet).Range("C2").Value = ProcessString(last_name) The last_name has to be declared as Dim last_name as string *10 ' size of string is up to you but must be a fix length

No need to change the function. Function doesn't take a fix length declaration.

I know this post is kinda old but...

  As 'witttness' pointed out.

About Your Own Custom Theme You might choose to modify bootstrap-theme.css when creating your own theme. Doing so may make it easier to make styling changes without accidentally breaking any of that built-in Bootstrap goodness.

  I see it as Bootstrap has seen over the years that everyone wants something a bit different than the core styles. While you could modify bootstrap.css it might break things and it could make updating to a newer version a real pain and time consuming. Downloading from a 'theme' site means you have to wait on if that creator updates that theme, big if sometimes, right?

  Some build their own 'custom.css' file and that's ok, but if you use 'bootstrap-theme.css' a lot of stuff is already built and this allows you to roll your own theme faster 'without' disrupting the core of bootstrap.css. I for one don't like the 3D buttons and gradients most of the time, so change them using bootstrap-theme.css. Add margins or padding, change the radius to your buttons, and so on...

String mQuery = "SELECT Name,Family From tblName";
Cursor mCur = db.rawQuery(mQuery, new String[]{});
mCur.moveToFirst();
while ( !mCur.isAfterLast()) {
        String name= mCur.getString(mCur.getColumnIndex("Name"));
        String family= mCur.getString(mCur.getColumnIndex("Family"));
        mCur.moveToNext();
}

Name and family are your result

Protected data members can be accessed by any classes that inherit from your class. Private data members, however, cannot. Let's say we have the following:

class MyClass {
    private:
        int myPrivateMember;    // lol
    protected:
        int myProtectedMember;
};

From within your extension to this class, referencing this.myPrivateMember won't work. However, this.myProtectedMember will. The value is still encapsulated, so if we have an instantiation of this class called myObj, then myObj.myProtectedMember won't work, so it is similar in function to a private data member.

As we can see in ActionController::Base, before_action is just a new syntax for before_filter.

However all before_filters syntax are deprecated in Rails 5.0 and will be removed in Rails 5.1

SELECT e.*,
       cnt.colCount 
FROM eventsTable e
INNER JOIN (
           select columnName,count(columnName) as colCount
           from eventsTable e2 
          group by columnName
           ) as cnt on cnt.columnName = e.columnName
WHERE e.columnName='Business'

-- Added space

This is the SQL Order of execution of a Query,

You can check order of execution with examples from this article.

For you question below lines might be helpful and directly got from this article.

3. GROUP BY --> The remaining rows after the WHERE constraints are applied are then grouped based on common values in the column specified in the GROUP BY clause. As a result of the grouping, there will only be as many rows as there are unique values in that column. Implicitly, this means that you should only need to use this when you have aggregate functions in your query.

4. HAVING --> If the query has a GROUP BY clause, then the constraints in the HAVING clause are then applied to the grouped rows, discard the grouped rows that don't satisfy the constraint. Like the WHERE clause, aliases are also not accessible from this step in most databases.

Like Babel says in the docs, for Babel > 7.4.0 the module @babel/polyfill is deprecated, so it's recommended to use directly core-js and regenerator-runtime libraries that before were included in @babel/polyfill.

So this worked for me:

npm install --save [email protected]
npm install regenerator-runtime

then add to the very top of your initial js file:

import 'core-js/stable';
import 'regenerator-runtime/runtime';

To answer your question:

If we can have inner private class then why can't we have outer private class...?

You can, the distinction is that the inner class is at the "class" access level, whereas the "outer" class is at the "package" access level. From the Oracle Tutorials:

If a class has no modifier (the default, also known as package-private), it is visible only within its own package (packages are named groups of related classes — you will learn about them in a later lesson.)

Thus, package-private (declaring no modifier) is the effect you would expect from declaring an "outer" class private, the syntax is just different.

Use Time YYYYDDDD (Year + Day of Year) as prefix. This decreases database fragmentation in tables and indexes. This method returns byte[40]. I used it in a hybrid environment where the Active Directory SID (varbinary(85)) is the key for LDAP users and an application auto-generated ID is used for non-LDAP Users. Also the large number of transactions per day in transactional tables (Banking Industry) cannot use standard Int types for Keys

private static final DecimalFormat timeFormat4 = new DecimalFormat("0000;0000");

public static byte[] getSidWithCalendar() {
    Calendar cal = Calendar.getInstance();
    String val = String.valueOf(cal.get(Calendar.YEAR));
    val += timeFormat4.format(cal.get(Calendar.DAY_OF_YEAR));
    val += UUID.randomUUID().toString().replaceAll("-", "");
    return val.getBytes();
}

The LockedOut property is what you are looking for among all the properties you returned. You are only seeing incomplete output in TechNet. The information is still there. You can isolate that one property using Select-Object

Get-ADUser matt -Properties * | Select-Object LockedOut

LockedOut
---------
False

The link you referenced doesn't contain this information which is obviously misleading. Test the command with your own account and you will see much more information.

Note: Try to avoid -Properties *. While it is great for simple testing it can make queries, especially ones with multiple accounts, unnecessarily slow. So, in this case, since you only need lockedout:

Get-ADUser matt -Properties LockedOut | Select-Object LockedOut

Below Different tools for Editing Rdlc report:

1. ReportBuilder 3.0 : Microsoft Editor for Rdlc report.
2. Microsoft® SQL Server® 2008 Express with Advanced Services: Another tool is to use Sql Server Business intelligence for reporting that can be installed with Sql Server Express with Advanced Sevices.
3. fyiReporting: It is opensource tool presented for editing Rdlc reports .

Use two dimensional array instead. For instance, int values[][] = new int[2][5]; Arrays are faster, when you are not manipulating much.

I encountered the same problem in the code and What I did is I found out all the changes I have made from the last correct compilation. And I have observed one function declaration was without ";" and also it was passing a value and I have declared it to pass nothing "void". this method will surely solve the problem for many.

You can add a form onsubmit handler, something like:

<form onsubmit="return validate();">

</form>


<script>function validate() {
 // check if input is bigger than 3
 var value = document.getElementById('titleeee').value;
 if (value.length < 3) {
   return false; // keep form from submitting
 }

 // else form is good let it submit, of course you will 
 // probably want to alert the user WHAT went wrong.

 return true;
}</script>

This is how I do it, and Google does it my way.

• Break before the symbol for non-assignment operators.
• Break after the symbol for = and for ,.

In your case, since you're using 120 characters, you can break it after the assignment operator resulting in

private static final Map<Class<? extends Persistent>, PersistentHelper> class2helper =
        new HashMap<Class<? extends Persistent>, PersistentHelper>();

In Java, and for this particular case, I would give two tabs (or eight spaces) after the break, depending on whether tabs or spaces are used for indentation.

This is of course a personal preference and if your project has its own convention for line-wrapping then that is what you should follow whether you like it or not.

If you define custom CSS you must set font-weight: 900; for some newer Font Awesome library (from version 5). Not setting this font-weight it may show squares.

If you want to use the new current standard, you can do so:

sub.emplace_back ("Math", 70, 0);

or

sub.push_back ({"Math", 70, 0});

These don't require default construction of subject.

Try:

<div style="@(Model.booleanVariable ? "display:block" : "display:none")">Some links</div>

Use the "Display" style attribute with your bool model attribute to define the div's visibility.

As we want to only separate lines, and the writelines function in python does not support adding separator between lines, I have written the simple code below which best suits this problem:

sep = "\n" # defining the separator
new_lines = sep.join(lines) # lines as an iterator containing line strings

and finally:

with open("file_name", 'w') as file:
    file.writelines(new_lines)

and you are done.

Just to update, following iOS 13, we now have SceneDelegates. So one might choose to put the desired tab selection in SceneDelegate.swift as follows:

class SceneDelegate: UIResponder, UIWindowSceneDelegate {

    var window: UIWindow?

    func scene(_ scene: UIScene, 
               willConnectTo session: UISceneSession, 
               options connectionOptions: UIScene.ConnectionOptions) {

        guard let _ = (scene as? UIWindowScene) else { return }

        if let tabBarController = self.window!.rootViewController as? UITabBarController {
            tabBarController.selectedIndex = 1
        }

    }

if ($done)
{
    header("Location: /url/to/the/other/page");
    exit;
}

There is no limit. It only depends on your free memory and system maximum file size. But that doesn't mean you shouldn't take precautionary measure in tackling memory usage in your database. Always create a script that can delete rows that are out of use or that will keep total no of rows within a particular figure, say a thousand.

a very simple solution would be, and I see you have said that you would like to see the simplest solution possible. A prompt for the user to continue after halting a loop Etc.

raw_input("Press<enter> to continue")

if you have multiple webview, localstorage does not work correctly.
two suggestion:

1. using java database instead webview localstorage that " @Guillaume Gendre " explained.(of course it does not work for me)
2. local storage work like json,so values store as "key:value" .you can add your browser unique id to it's key and using normal android localstorage

The point is to set the token on the interceptors for each request

The version of the errorHandler middleware bundled with some (perhaps older?) versions of express seems to have the status code hardcoded. The version documented here: http://www.senchalabs.org/connect/errorHandler.html on the other hand lets you do what you are trying to do. So, perhaps trying upgrading to the latest version of express/connect.

For Visual Studio 2010/2013/2015/2017/2019

• Format Document (Ctrl+K,Ctrl+D) so type Ctrl+K, AND THEN Ctrl+D as it is a sequence
• Format Selection (Ctrl+K,Ctrl+F)

Toolbar Edit -> Advanced (If you can't see Advanced, select a code file in solution explorer and try again)

Your shortcuts might display differently to mine as I am set up for C# coding but navigating via the toolbar will get you to your ones.

If it isn't working, look for errors in your code, like missing brackets which stop auto format from working

I would create a property to access the variable, like this:

protected string Test
{
    get; set;
}

And in your markup:

<%= this.Test %>

Not seeing the need for any object malarky myself. Simple have a variable which is an integer. When you start a request, increment the number. When one completes, decrement it. When it's zero, there are no requests in progress, so you're done.

$('#button').click(function() {
    var inProgress = 0;

    function handleBefore() {
        inProgress++;
    };

    function handleComplete() {
        if (!--inProgress) {
            // do what's in here when all requests have completed.
        }
    };

    $.ajax({
        beforeSend: handleBefore,
        complete: function () {
            // whatever
            handleComplete();
            // whatever
        }
    });
    $.ajax({
        beforeSend: handleBefore,
        complete: function () {
            // whatever
            handleComplete();
            // whatever
        }
    });
    $.ajax({
        beforeSend: handleBefore,
        complete: function () {
            // whatever
            handleComplete();
            // whatever
        }
    });
});

You can not do it as a member function, because the implicit this parameter is the left hand side of the <<-operator. (Hence, you would need to add it as a member function to the ostream-class. Not good :)

Could you do it as a free function without friending it? That's what I prefer, because it makes it clear that this is an integration with ostream, and not a core functionality of your class.

Simply u can add this to jquery.validationEngine-en.js file

    "onlyLetterNumberSp": {
                "regex": ^[A-Za-z0-9 _]*[A-Za-z0-9][A-Za-z0-9 _]*$,
                "alertText": "* No special characters allowed"
          },

and call it in text field as

<input type="text" class="form-control validate[required,custom[onlyLetterNumberSp]]"  id="title" name="title" placeholder="Title"/>

On Ubuntu Server 16, I have the same problem with python27. Try this:

Change

from pip import main
if __name__ == '__main__':
    sys.exit(main())

To

from pip._internal import main
if __name__ == '__main__':
    sys.exit(main())

Place this at the top of your script. It will cause the script to prompt the user for a password. The resulting password can then be used elsewhere in your script via $pw.

   Param(
     [Parameter(Mandatory=$true, Position=0, HelpMessage="Password?")]
     [SecureString]$password
   )

   $pw = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($password))

If you want to debug and see the value of the password you just read, use:

   write-host $pw

A simple forEach loop solves this quite well:

let text = 'the red apple and the green ball';
const toStrip = ['red', 'green'];
toStrip.forEach(x => {
   text = text.replace(x, '');
});

console.log(text);
// logs -> the apple and the ball

date.setTime( date.getTime() + days * 86400000 );

ansible -m setup hostname

Only gets the facts gathered by the setup module.

Gilles Cornu posted a template trick to list all variables for a specific host.

Template (later called dump_variables):

HOSTVARS (ANSIBLE GATHERED, group_vars, host_vars) :

{{ hostvars[inventory_hostname] | to_yaml }}

PLAYBOOK VARS:

{{ vars | to_yaml }}

Playbook to use it:

- hosts: all
  tasks:
  - template:
      src: templates/dump_variables
      dest: /tmp/ansible_variables
  - fetch:
      src: /tmp/ansible_variables
      dest: "{{inventory_hostname}}_ansible_variables"

After that you have a dump of all variables on every host, and a copy of each text dump file on your local workstation in your tmp folder. If you don't want local copies, you can remove the fetch statement.

This includes gathered facts, host variables and group variables. Therefore you see ansible default variables like group_names, inventory_hostname, ansible_ssh_host and so on.

Add necessary namespace

using System.Linq;

Then you can use linq Contains() method

string[] printer = {"jupiter", "neptune", "pangea", "mercury", "sonic"};
if(printer.Contains("jupiter"))
{
    Process.Start("BLAH BLAH CODE TO ADD PRINTER VIA WINDOWS EXEC"");
}

Javascript function to search an array of tags or keywords using a search string or an array of search strings. (Uses ES5 some array method and ES6 arrow functions)

// returns true for 1 or more matches, where 'a' is an array and 'b' is a search string or an array of multiple search strings
function contains(a, b) {
    // array matches
    if (Array.isArray(b)) {
        return b.some(x => a.indexOf(x) > -1);
    }
    // string match
    return a.indexOf(b) > -1;
}

Example usage:

var a = ["a","b","c","d","e"];
var b = ["a","b"];
if ( contains(a, b) ) {
    // 1 or more matches found
}

DiffUtil can the best choice for updating the data in the RecyclerView Adapter which you can find in the android framework. DiffUtil is a utility class that can calculate the difference between two lists and output a list of update operations that converts the first list into the second one.

Most of the time our list changes completely and we set new list to RecyclerView Adapter. And we call notifyDataSetChanged to update adapter. NotifyDataSetChanged is costly. DiffUtil class solves that problem now. It does its job perfectly!

I had the same problem when I install python3.5.3. And finally I find the pip.exe in this folder: ~/python/scripts/pip.exe. Hope that help.

All you have to do is have a height of 100vh on your main container/wrapper, and then set height 100% or 50% for child elements.. depending on what you're trying to achieve. I tried to copy your mock up in a basic sense.

In case you want to center stuff within, look into flexbox. I put in an example for you.

You can view it on full screen, and resize the browser and see how it works. The layout stays the same.

Does not seem like it, but android recognises a webcam as a device. Every time I run the emulator my webcam's active light comes on.

The only standard mandated implementation dependent way is to use the system() function from stdlib.h.

Also if you know how to make user become the super-user that would be nice also.

Do you want the script to run as super-user or do you want to elevate the privileges of the C executable? The former can be done with sudo but there are a few things you need to know before you can go off using sudo.

We can use substring. Here's the example,

public class RemoveStringChar 
{
    public static void main(String[] args) 
    {   
        String strGiven = "Java";
        System.out.println("Before removing string character - " + strGiven);
        System.out.println("After removing string character - " + removeCharacter(strGiven, 3));
    }

    public static String removeCharacter(String strRemove, int position)
    {   
        return strRemove.substring(0, position) + strRemove.substring(position + 1);    
    }
}

Left Click on the WAMP icon the system try -> PHP -> PHP Extensions -> Enable php_curl

Easy way of doing it would be:

<input type="file" accept=".gif,.jpg,.jpeg,.png,.doc,.docx">

Works with all browsers, except IE9. I haven't tested it in IE10+.

To get timestamp from NSDate Swift 3

func getCurrentTimeStampWOMiliseconds(dateToConvert: NSDate) -> String {
    let objDateformat: DateFormatter = DateFormatter()
    objDateformat.dateFormat = "yyyy-MM-dd HH:mm:ss"
    let strTime: String = objDateformat.string(from: dateToConvert as Date)
    let objUTCDate: NSDate = objDateformat.date(from: strTime)! as NSDate
    let milliseconds: Int64 = Int64(objUTCDate.timeIntervalSince1970)
    let strTimeStamp: String = "\(milliseconds)"
    return strTimeStamp
}

To use

let now = NSDate()
let nowTimeStamp = self.getCurrentTimeStampWOMiliseconds(dateToConvert: now)

There can be a case where the process is complete before waiting for the process. If we trigger wait for a process that is already finished, it will trigger an error like pid is not a child of this shell. To avoid such cases, the following function can be used to find whether the process is complete or not:

isProcessComplete(){
PID=$1
while [ -e /proc/$PID ]
do
    echo "Process: $PID is still running"
    sleep 5
done
echo "Process $PID has finished"
}

If you do choose to roll your own, rather than use an existing library, please be conscious of floating point error and try to minimize its effects:

class SumAccumulator:
    def __init__(self):
        self.values = [0]
        self.count = 0

    def add( self, val ):
        self.values.append( val )
        self.count = self.count + 1
        i = self.count
        while i & 0x01:
            i = i >> 1
            v0 = self.values.pop()
            v1 = self.values.pop()
            self.values.append( v0 + v1 )

    def get_total(self):
        return sum( reversed(self.values) )

    def get_size( self ):
        return self.count

If all your values are roughly the same order of magnitude, then this will help to preserve precision by always adding values of roughly similar magnitudes.

Hai Vu answer works great, just one comment:

In case you are using the global in other module and you want to set the global dynamically, pay attention to import the other modules after you set the global variables, for example:

# settings.py
def init(arg):
    global myList
    myList = []
    mylist.append(arg)


# subfile.py
import settings

def print():
    settings.myList[0]


# main.py
import settings
settings.init("1st")     # global init before used in other imported modules
                         # Or else they will be undefined

import subfile    
subfile.print()          # global usage

Just some thoughts on my case.

If you have changed the dbPath and logPath dirs to your custom values (say /data/mongodb/data, /data/mongodb/log), you must chown them to mongodb user, otherwise, the non-existent /data/db/ dir will be used.

sudo chown -R mongodb:mongodb /data/mongodb/

sudo service mongod restart

In your Log4net config file, use the following parameter with the RollingFileAppender:

<param name="DatePattern" value="dd.MM.yyyy'.log'" />

You should move it:

Directory.Move(source, destination);

Using Common Table Expression (CTE)

WITH CTE AS(
    SELECT ROW_NUMBER() OVER(ORDER BY CustomerId) AS RowNumber,
    Customers.*
    FROM Customers
)
SELECT * FROM CTE

Good solution from bmu. I think it's more readable to put the values inside the parentheses vs outside.

    df['Values'] = np.where(df.Action == 'Sell', 
                            df.Prices*df.Amount, 
                           -df.Prices*df.Amount)

Using some pandas built in functions.

    df['Values'] = np.where(df.Action.eq('Sell'), 
                            df.Prices.mul(df.Amount), 
                           -df.Prices.mul(df.Amount))

SELECT a.C_ID,a.QRY_ID,a.RES_ID,b.SCORE,ROW_NUMBER() OVER (ORDER BY SCORE DESC) AS [RANK]
FROM CONTACTS a JOIN RSLTS b ON a.QRY_ID=b.QRY_ID AND a.RES_ID=b.RES_ID
ORDER BY a.C_ID

It could be a good idea to be careful with the Locale upon which c.getTime().toString(); depends.

One idea is to store the time in seconds (e.g. UNIX time). As an int you can easily compare it, and then you just convert it to string when displaying it to the user.

I had same problem and the problem was that I was not closing socket object.After using socket.close(); problem solved. This code works for me.

ClientDemo.java

public class ClientDemo {
    public static void main(String[] args) throws UnknownHostException,
            IOException {
        Socket socket = new Socket("127.0.0.1", 55286);
        OutputStreamWriter os = new OutputStreamWriter(socket.getOutputStream());
        os.write("Santosh Karna");
        os.flush();
        socket.close();
    }
}

and ServerDemo.java

public class ServerDemo {
    public static void main(String[] args) throws IOException {
        System.out.println("server is started");
        ServerSocket serverSocket= new ServerSocket(55286);
        System.out.println("server is waiting");
        Socket socket=serverSocket.accept();
        System.out.println("Client connected");
        BufferedReader reader=new BufferedReader(new InputStreamReader(socket.getInputStream()));
        String str=reader.readLine();
        System.out.println("Client data: "+str);
        socket.close();
        serverSocket.close();

    }
}

COPY <all> <the> <things> <last-arg-is-destination>

But here is an important excerpt from the docs:

If you have multiple Dockerfile steps that use different files from your context, COPY them individually, rather than all at once. This ensures that each step’s build cache is only invalidated (forcing the step to be re-run) if the specifically required files change.

https://docs.docker.com/develop/develop-images/dockerfile_best-practices/#add-or-copy

Depending on your Java class package name, you're probably 4 or 5 levels down the directory structure.

If your Java class package is, for example, com.stackoverflow.project, then your class is located at src/com/stackoverflow/project.

You can either move up the directory structure with multiple ../, or you can move the text file to the same package as your class. It would be easier to move the text file.

There is no keyboard shortcut for restoring the perspective directly AFAIK. To open the Window menu (where Reset Perspective resides), try Alt-W. If that does not work, I guess your Eclipse has hung for some reason. Another shortcut you might want to try is F10 (should open the main menu).

In my case it works only with two line of code. Test the below C# code:

String dirPath = "C:\myfolder\";
String imgName = "my_mage_name.bmp";

byte[] imgByteArray = Convert.FromBase64String("your_base64_string");
File.WriteAllBytes(dirPath + imgName, imgByteArray);

That's it. Kindly up vote if you really find this solution works for you. Thanks in advance.

I've been having this problem in Linux, with a project that I renamed, removed, and reimported. Somewhere in the .metadata, it's still there evidently.

I finally solved it by the following steps:

close Eclipse
mv .metadata .metadata_orig
start Eclipse
reset default workspace
reimport projects

This may not work for everyone, especially if you already have lots of projects in multiple workspaces. But if you're used to reconfiguring Eclipse (which I do every time I upgrade to the next Eclipse release) it's not too bad.

We can use the modulo (%) operator. This tells us how many remainders we have when we divide x by y - expresses as x % y. Every whole number must divide by 1, so if there is a remainder, it must not be a whole number.

This function will return a boolean, True or False, depending on whether n is a whole number.

def is_whole(n):
    return n % 1 == 0

I use the program SQLYOG where I can make a select query, point at the results and choose export as sql. This gives me the insert statements.

Try jcabi-http, which is a fluent Java HTTP client, for example:

String html = new JdkRequest("https://www.google.com")
  .header(HttpHeaders.ACCEPT, MediaType.TEXT_HTML)
  .fetch()
  .as(HttpResponse.class)
  .assertStatus(HttpURLConnection.HTTP_OK)
  .body();

Check also this blog post: http://www.yegor256.com/2014/04/11/jcabi-http-intro.html

I would change your service layer to:

public Task<BackOfficeResponse<List<Country>>> ReturnAllCountries()
{
    return Task.Run(() =>
    {
        return _service.Process<List<Country>>(BackOfficeEndpoint.CountryEndpoint, "returnCountries");
    }      
}

as you have it, you are still running your _service.Process call synchronously, and gaining very little or no benefit from awaiting it.

With this approach, you are wrapping the potentially slow call in a Task, starting it, and returning it to be awaited. Now you get the benefit of awaiting the Task.

In Windows OS the following commands works for me.

mysql>Use <DatabaseName>
mysql>SOURCE C:/data/ScriptFile.sql;

No single quotes or double quotes around file name. Path would contain '/' instead of '\'.

1)row level trigger is used to perform action on set of rows as insert , update or delete

example:-you have to delete a set of rows and simultaneously that deleted rows must also inserted in new table for audit purpose;

2)statement level trigger:- it generally used to imposed restriction on the event you are performing.

example:- restriction to delete the data between 10 pm and 6 am;

hope this helps:)

Install from the "Unofficial Windows Binaries for Python Extension Packages"

Pretty much has every package you would need.

String a []=new String[1];

  a[0].add("kk" );
  a[1].add("pp");

Try this one...

You can simply use the jQuery Validate plugin as follows.

jQuery:

$(document).ready(function () {

    $('#myform').validate({ // initialize the plugin
        rules: {
            field1: {
                required: true,
                email: true
            },
            field2: {
                required: true,
                minlength: 5
            }
        }
    });

});

HTML:

<form id="myform">
    <input type="text" name="field1" />
    <input type="text" name="field2" />
    <input type="submit" />
</form>

I know is too late, but for somebody whit the same need editText.setFocusable(false) si what you are looking for.

A slightly faster option than using the already mentioned use of the Join() method is the Concat() method. It doesn't require an empty delimiter parameter as Join() does. Example:

string[] test = new string[2];
test[0] = "Hello ";
test[1] = "World!";

string result = String.Concat(test);

hence it is likely faster.

If you want multiple string replacement:

NSString *s = @"foo/bar:baz.foo";
NSCharacterSet *doNotWant = [NSCharacterSet characterSetWithCharactersInString:@"/:."];
s = [[s componentsSeparatedByCharactersInSet: doNotWant] componentsJoinedByString: @""];
NSLog(@"%@", s); // => foobarbazfoo

This is kinda besides the point, but since the question is tagged best-practices I'll go ahead and throw in my two cents. For this type of thing I greatly prefer to make it into a property:

public static IEnumerable<Product> AllProducts
{
    get {
        using (AdventureWorksEntities db = new AdventureWorksEntities()) {
            var products = from product in db.Product
                           select product;

            return products;
        }
    }
}

Sure, it's a little more boiler-plate, but the code that uses this will look much cleaner:

prices = Whatever.AllProducts.Select (product => product.price);

vs

prices = Whatever.GetAllProducts().Select (product => product.price);

Note: I wouldn't do this for any methods that may take a while to do their work.

In 2017 you can do this (saying this because this thread is almost 9 years old!)

function copyStringToClipboard (string) {
    function handler (event){
        event.clipboardData.setData('text/plain', string);
        event.preventDefault();
        document.removeEventListener('copy', handler, true);
    }

    document.addEventListener('copy', handler, true);
    document.execCommand('copy');
}

And now to copy copyStringToClipboard('Hello World')

If you noticed the setData line, and wondered if you can set different data types the answer is yes.

To me it happened in DogController that autowired DogService that autowired DogRepository. Dog class used to have field name but I changed it to coolName, but didn't change methods in DogRepository: Dog findDogByName(String name). I change that method to Dog findDogByCoolName(String name) and now it works.

I've made something like the following code :)

It works only, when you have a second file named with _hover, for example, facebook.png and facebook_hover.png

$('#social').find('a').hover(function() {
    var target = $(this).find('img').attr('src');
    //console.log(target);
    var newTarg = target.replace('.png', '_hover.png');
    $(this).find('img').attr("src", newTarg);
}, function() {
    var target = $(this).find('img').attr('src');
    var newTarg = target.replace('_hover.png', '.png');
    $(this).find('img').attr("src", newTarg);
});

Thanks to @user2630576 and @Ed.S.

the following worked a treat:

GO

ALTER DATABASE [database] SET RECOVERY SIMPLE

use [database]

declare @log_File_Name varchar(200)

select @log_File_Name = name from sysfiles where filename like '%LDF'

declare @i int = FILE_IDEX ( @log_File_Name)

dbcc shrinkfile ( @i , 50)

ALTER DATABASE [database] SET RECOVERY FULL

This is a speed test about different ways to test "Boolean" values in Bash:

#!/bin/bash
rounds=100000

b=true # For true; b=false for false
type -a true
time for i in $(seq $rounds); do command $b; done
time for i in $(seq $rounds); do $b; done
time for i in $(seq $rounds); do [ "$b" == true ]; done
time for i in $(seq $rounds); do test "$b" == true; done
time for i in $(seq $rounds); do [[ $b == true ]]; done

b=x; # Or any non-null string for true; b='' for false
time for i in $(seq $rounds); do [ "$b" ]; done
time for i in $(seq $rounds); do [[ $b ]]; done

b=1 # Or any non-zero integer for true; b=0 for false
time for i in $(seq $rounds); do ((b)); done

It would print something like

true is a shell builtin
true is /bin/true

Got my sample working: I just inserted 'Access-Control-Allow-Origin': '*', inside headers:{} in the generated nodejs Lambda function. I made no changes to the Lambda-generated API layer.

Here's my NodeJS:

'use strict';
const doc = require('dynamodb-doc');
const dynamo = new doc.DynamoDB();
exports.handler = ( event, context, callback ) => {
    const done = ( err, res ) => callback( null, {
        statusCode: err ? '400' : '200',
        body: err ? err.message : JSON.stringify(res),
        headers:{ 'Access-Control-Allow-Origin' : '*' },
    });
    switch( event.httpMethod ) {
        ...
    }
};

Here's my AJAX call

$.ajax({
    url: 'https://x.execute-api.x-x-x.amazonaws.com/prod/fnXx?TableName=x',
    type: 'GET',
    beforeSend: function(){ $( '#loader' ).show();},
    success: function( res ) { alert( JSON.stringify(res) ); },
    error:function(e){ alert('Lambda returned error\n\n' + e.responseText); },
    complete:function(){ $('#loader').hide(); }
});

Sounds like you only installed the MySQL Client Tools (MySQL Workbench). You have to install the MySQL Database server, configure and start it.

http://dev.mysql.com/downloads/

You probably want the MySQL Community Server download.

If you want to add multiple files in a given folder you can split them using {,}. This is awesome for not repeating long paths, e.g.

git add long/path/{file1,file2,...,filen}

Beware not to put spaces between the ,.

It sounds like you've already decided that Project Lombok gives you significant technical advantages for your proposed new project. (To be clear from the start, I have no particular views on Project Lombok, one way or the other.)

Before you use Project Lombok (or any other game-changing technology) in some project (open source or other wise), you need to make sure that the project stake holders agree to this. This includes the developers, and any important users (e.g. formal or informal sponsors).

You mention these potential issues:

Flamewars will erupt in the ##Java Freenode channel when I mention it,

Easy. Ignore / don't participate in the flamewars, or simply refrain from mentioning Lombok.

providing code snippets will confuse possible helpers,

If the project strategy is to use Lombok, then the possible helpers will need to get used to it.

people will complain about missing JavaDoc,

That is their problem. Nobody in their right mind tries to rigidly apply their organization's source code / documentation rules to third-party open source software. The project team should be free to set project source code / documentation standards that are appropriate to the technology being used.

(FOLLOWUP - The Lombok developers recognize that not generating javadoc comments for synthesized getter and setter methods is an issue. If this is a major problem for your project(s), then one alternative is to create and submit a Lombok patch to address this.)

and future commiters might just remove it all anyway.

That's not on! If the agreed project strategy is to use Lombok, then commiters who gratuitously de-Lombok the code should be chastised, and if necessary have their commit rights withdrawn.

Of course, this assumes that you've got buy-in from the stakeholders ... including the developers. And it assumes that you are prepared to argue your cause, and appropriately handle the inevitable dissenting voices.

C# (before C# 6) doesn't support CIL "filtered exceptions", which VB does, so in C# 1-5 one reason for re-throwing an exception is that you don't have enough information at the time of catch() to determine whether you wanted to actually catch the exception.

For example, in VB you can do

Try
 ..
Catch Ex As MyException When Ex.ErrorCode = 123
 .. 
End Try

...which would not handle MyExceptions with different ErrorCode values. In C# prior to v6, you would have to catch and re-throw the MyException if the ErrorCode was not 123:

try 
{
   ...
}
catch(MyException ex)
{
    if (ex.ErrorCode != 123) throw;
    ...
}

Since C# 6.0 you can filter just like with VB:

try 
{
  // Do stuff
} 
catch (Exception e) when (e.ErrorCode == 123456) // filter
{
  // Handle, other exceptions will be left alone and bubble up
}

string[] friends = new string[4];
friends[0]= "ali";
friends[1]= "Mike";
friends[2]= "jan";
friends[3]= "hamid";

for (int i = 0; i < friends.Length; i++)
{
    Console.WriteLine(friends[i]);
}Console.ReadLine();

Well you can remove the third calendar instance.

GregorianCalendar c1 = new GregorianCalendar();
GregorianCalendar c2 = new GregorianCalendar();
c1.set(2000, 1, 1);
c2.set(2010,1, 1);
c2.add(GregorianCalendar.MILLISECOND, -1 * c1.getTimeInMillis());

I assume you want all the items next to each other, and the whole thing to be centered horizontally.

li elements are display: block by default, taking up all the horizontal space.

Add

div#footer ul li { display: inline }

once you've done that, you probably want to get rid of the list's bullets:

div#footer ul { list-style-type: none; padding: 0px; margin: 0px }

Put double quotes around the path that has spaces like this:

REGSVR32 "E:\Documents and Settings\All Users\Application Data\xyz.dll"

With the support of CSS custom properties (variables) in iOS, you can set these with JS and use them on iOS only.

const iOS = /iPad|iPhone|iPod/.test(navigator.userAgent) && !window.MSStream;
if (iOS) {
  document.body.classList.add('ios');
  const vh = window.innerHeight / 100;
  document.documentElement.style
    .setProperty('--ios-10-vh', `${10 * vh}px`);
  document.documentElement.style
    .setProperty('--ios-50-vh', `${50 * vh}px`);
  document.documentElement.style
    .setProperty('--ios-100-vh', `${100 * vh}px`);
}

body.ios {
    .side-nav {
        top: var(--ios-50-vh);
    }
    section {
        min-height: var(--ios-100-vh);
        .container {
            position: relative;
            padding-top: var(--ios-10-vh);
            padding-bottom: var(--ios-10-vh);
        }
    }
}

It help me to clean a system, with MVC in CakePhp, as i work in Linux, Windows, with different tools.. in some files my design was break.. so after checkin in Chrome with debug tool find the &#65279 error

From Hadoop page,

start-all.sh 

This will startup a Namenode, Datanode, Jobtracker and a Tasktracker on your machine.

start-dfs.sh

This will bring up HDFS with the Namenode running on the machine you ran the command on. On such a machine you would need start-mapred.sh to separately start the job tracker

start-all.sh/stop-all.sh has to be run on the master node

You would use start-all.sh on a single node cluster (i.e. where you would have all the services on the same node.The namenode is also the datanode and is the master node).

In multi-node setup,

You will use start-all.sh on the master node and would start what is necessary on the slaves as well.

Alternatively,

Use start-dfs.sh on the node you want the Namenode to run on. This will bring up HDFS with the Namenode running on the machine you ran the command on and Datanodes on the machines listed in the slaves file.

Use start-mapred.sh on the machine you plan to run the Jobtracker on. This will bring up the Map/Reduce cluster with Jobtracker running on the machine you ran the command on and Tasktrackers running on machines listed in the slaves file.

hadoop-daemon.sh as stated by Tariq is used on each individual node. The master node will not start the services on the slaves.In a single node setup this will act same as start-all.sh.In a multi-node setup you will have to access each node (master as well as slaves) and execute on each of them.

Have a look at this start-all.sh it call config followed by dfs and mapred

To remove all child elements from your div:

$('#mysweetdiv').empty();

.removeData() and the corresponding .data() function are used to attach data behind an element, say if you wanted to note that a specific list element referred to user ID 25 in your database:

var $li = $('<li>Joe</li>').data('id', 25);

Simplified for Kotlin:

val widthDp = resources.displayMetrics.run { widthPixels / density }
val heightDp = resources.displayMetrics.run { heightPixels / density }

There's an related question to which I answered:

#pragma once does have one drawback (other than being non-standard) and that is if you have the same file in different locations (we have this because our build system copies files around) then the compiler will think these are different files.

I'm adding the answer here too in case someone stumbles over this question and not the other.

Absolute positioning positions an element relative to its nearest positioned ancestor. So put position: relative on the container, then for child elements, top and left will be relative to the top-left of the container so long as the child elements have position: absolute. More information is available in the CSS 2.1 specification.

While the solution provided by @jmfenoll works, it updates to the latest packages. In my case, having installed beta2 (prerelease) it updated all of the libs to RC1 (which had a bug). Thus the above solution does only half of the job.

If you are in the same situation as I am and you would like to synchronize your project with the exact version of the NuGet packages you have/or specified in your packages.config, then, then this script might help you. Simply copy&paste it into your Package Manager Console

function Sync-References([string]$PackageId) {
  get-project -all | %{
    $proj = $_ ;
    Write-Host $proj.name; 
    get-package -project $proj.name | ? { $_.id -match $PackageId } | % { 
      Write-Host $_.id; 
      uninstall-package -projectname $proj.name -id $_.id -version $_.version -RemoveDependencies -force ;
      install-package -projectname $proj.name -id $_.id -version $_.version
    }
  }
}

And then execute it either with a sepific package name like

Sync-References AutoMapper

or for all packages like

Sync-References

Make sure you saved the file as JavaScript. Un check 'Hide extensions for all known type' check box in Folder Options window will show you the correct file extension(Folder>>view>>Option).

On Windows the easiest way is to use the program portecle.

1. Download and install portecle.
2. First make 100% sure you know which JRE or JDK is being used to run your program. On a 64 bit Windows 7 there could be quite a few JREs. Process Explorer can help you with this or you can use: System.out.println(System.getProperty("java.home"));
3. Copy the file JAVA_HOME\lib\security\cacerts to another folder.
4. In Portecle click File > Open Keystore File
5. Select the cacerts file
6. Enter this password: changeit
7. Click Tools > Import Trusted Certificate
8. Browse for the file mycertificate.pem
9. Click Import
10. Click OK for the warning about the trust path.
11. Click OK when it displays the details about the certificate.
12. Click Yes to accept the certificate as trusted.
13. When it asks for an alias click OK and click OK again when it says it has imported the certificate.
14. Click save. Don’t forget this or the change is discarded.
15. Copy the file cacerts back where you found it.

On Linux:

You can download the SSL certificate from a web server that is already using it like this:

$ echo -n | openssl s_client -connect www.example.com:443 | \
   sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/examplecert.crt

Optionally verify the certificate information:

$ openssl x509 -in /tmp/examplecert.crt -text

Import the certificate into the Java cacerts keystore:

$ keytool -import -trustcacerts -keystore /opt/java/jre/lib/security/cacerts \
   -storepass changeit -noprompt -alias mycert -file /tmp/examplecert.crt

The best option is to use the original LESS version of bootstrap (get it from github).

Open variables.less and look for // Media queries breakpoints

Find this code and change the breakpoint value:

// Large screen / wide desktop
@screen-lg:                  1200px; // change this
@screen-lg-desktop:          @screen-lg;

Change it to 9999px for example, and this will prevent the breakpoint to be reached, so your site will always load the previous media query which has 940px container

also you can reimplement protected member QWidget::closeEvent()

void YourWidgetWithXButton::closeEvent(QCloseEvent *event)
{
    // do what you need here
    // then call parent's procedure
    QWidget::closeEvent(event);
}

If anyone is interested in getting the localized string from the property with DisplayAttribute and ResourceType like this:

[Display(Name = "Year", ResourceType = typeof(ArrivalsResource))]
public int Year { get; set; }

Use the following after displayAttribute != null (as shown above by @alex' answer):

ResourceManager resourceManager = new ResourceManager(displayAttribute.ResourceType);
var entry = resourceManager.GetResourceSet(Thread.CurrentThread.CurrentUICulture, true, true)
                           .OfType<DictionaryEntry>()
                           .FirstOrDefault(p => p.Key.ToString() == displayAttribute.Name);

return entry.Value.ToString();

I changed '\n' for chr(10) and it worked:

$pdf->MultiCell(0,5,utf8_decode($variable1 . chr(10) . $variable2),1);

Two solutions: One simple and one more advanced.

Introduction

There are two solutions available to you depending on the severity of your issue

Replace with your own values, as follows:

• Replace XXXMYINDEXXXX with the name of an index.
• Replace XXXMYTABLEXXX with the name of a table.
• Replace XXXDATABASENAMEXXX with the name of a database.

Solution 1. Indexing

Rebuild all indexes for a table in offline mode

ALTER INDEX ALL ON XXXMYTABLEXXX REBUILD

Rebuild one specified index for a table in offline mode

ALTER INDEX XXXMYINDEXXXX ON XXXMYTABLEXXX REBUILD

Solution 2. Fragmentation

Fragmentation is an issue in tables that regularly have entries both added and removed.

Check fragmentation percentage

SELECT  
    ips.[index_id] ,
    idx.[name] ,
    ips.[avg_fragmentation_in_percent]
FROM    
    sys.dm_db_index_physical_stats(DB_ID(N'XXXMYDATABASEXXX'), OBJECT_ID(N'XXXMYTABLEXXX'), NULL, NULL, NULL) AS [ips]
    INNER JOIN sys.indexes AS [idx] ON [ips].[object_id] = [idx].[object_id] AND [ips].[index_id] = [idx].[index_id]

Fragmentation 5..30%

If the fragmentation value is greater than 5%, but less than 30% then it is worth reorganising indexes.

Reorganise all indexes for a table

ALTER INDEX ALL ON XXXMYTABLEXXX REORGANIZE

Reorganise one specified index for a table

ALTER INDEX XXXMYINDEXXXX ON XXXMYTABLEXXX REORGANIZE

Fragmentation 30%+

If the fragmentation value is 30% or greater then it is worth rebuilding then indexes in online mode.

Rebuild all indexes in online mode for a table

ALTER INDEX ALL ON XXXMYTABLEXXX REBUILD WITH (ONLINE = ON)

Rebuild one specified index in online mode for a table

ALTER INDEX XXXMYINDEXXXX ON XXXMYTABLEXXX REBUILD WITH (ONLINE = ON)

The following command worked for me. Docker file was placed in my-app-master folder.

docker build -f my-app-master/Dockerfile -t my-app-master .

Just use your window with the WindowsInteropHelper class:

// ... Window myWindow = get your Window instance...
IntPtr windowHandle = new WindowInteropHelper(myWindow).Handle;

Right now, you're asking for the Application's main window, of which there will always be one. You can use this same technique on any Window, however, provided it is a System.Windows.Window derived Window class.

There was a change from 1.3.x to 1.4.x.

In Angular 1.3.x this worked:

var dir: ng.IDirective = {
    restrict: "A",
    require: ["select", "ngModel"],
    compile: compile,
};

function compile(tElement: ng.IAugmentedJQuery, tAttrs, transclude) {
    tElement.append("<option value=''>--- Kein ---</option>");

    return function postLink(scope: DirectiveScope, element: ng.IAugmentedJQuery, attributes: ng.IAttributes) {
        attributes["ngOptions"] = "a.ID as a.Bezeichnung for a in akademischetitel";
        scope.akademischetitel = AkademischerTitel.query();
    }
}

Now in Angular 1.4.x we have to do this:

var dir: ng.IDirective = {
    restrict: "A",
    compile: compile,
    terminal: true,
    priority: 10,
};

function compile(tElement: ng.IAugmentedJQuery, tAttrs, transclude) {
    tElement.append("<option value=''>--- Kein ---</option>");
    tElement.removeAttr("tq-akademischer-titel-select");
    tElement.attr("ng-options", "a.ID as a.Bezeichnung for a in akademischetitel");

    return function postLink(scope: DirectiveScope, element: ng.IAugmentedJQuery, attributes: ng.IAttributes) {

        $compile(element)(scope);
        scope.akademischetitel = AkademischerTitel.query();
    }
}

(From the accepted answer: https://stackoverflow.com/a/19228302/605586 from Khanh TO).

An additional method:

As was already mentioned, you could convert the original String "name" to a char array quite easily:

String originalString = "name";
char[] charArray = originalString.toCharArray();

To continue this train of thought, you could then convert the char array to a String array:

String[] stringArray = new String[charArray.length];
for (int i = 0; i < charArray.length; i++){
    stringArray[i] = String.valueOf(charArray[i]);
}

At this point, your stringArray will be filled with the original values from your original string "name". For example, now calling

System.out.println(stringArray[0]);

Will return the value "n" (as a String) in this case.

May be helpful for late comers.

#include "stdafx.h"
#include "cv.h"
#include "highgui.h"

using namespace cv;
using namespace std;

int main(int argc, char *argv[])
{
  if (argc != 2) {
    cout << "Usage: display_Image ImageToLoadandDisplay" << endl;
    return -1;
}else{
    Mat image;
    Mat grayImage;

    image = imread(argv[1], IMREAD_COLOR);
    if (!image.data) {
        cout << "Could not open the image file" << endl;
        return -1;
    }
    else {
        int height = image.rows;
        int width = image.cols;

        cvtColor(image, grayImage, CV_BGR2GRAY);


        namedWindow("Display window", WINDOW_AUTOSIZE);
        imshow("Display window", image);

        namedWindow("Gray Image", WINDOW_AUTOSIZE);
        imshow("Gray Image", grayImage);
        cvWaitKey(0);
        image.release();
        grayImage.release();
        return 0;
    }

  }

}

The following code creates an anonymous struct with the alias myStruct:

typedef struct{
    int one;
    int two;
} myStruct;

You can't refer it without the alias because you don't specify an identifier for the structure.

I bumped into this problem lately with Windows 10 from another direction, and found the answer from @JonSkeet very helpful in solving my problem.

I also did som further research with a test form and found that when the the current culture was set to "no" or "nb-NO" at runtime (Thread.CurrentThread.CurrentCulture = new CultureInfo("no");), the ToString("yyyy-MM-dd HH:mm:ss") call responded differently in Windows 7 and Windows 10. It returned what I expected in Windows 7 and HH.mm.ss in Windows 10!

I think this is a bit scary! Since I believed that a culture was a culture in any Windows version at least.

The first argument of strcat() needs to be able to hold enough space for the concatenated string. So allocate a buffer with enough space to receive the result.

char bigEnough[64] = "";

strcat(bigEnough, "TEXT");
strcat(bigEnough, foo);

/* and so on */

strcat() will concatenate the second argument with the first argument, and store the result in the first argument, the returned char* is simply this first argument, and only for your convenience.

You do not get a newly allocated string with the first and second argument concatenated, which I'd guess you expected based on your code.

What system are you using? Webpack? Vue-loader?

I'll only brainstorming here...

Because .png is not a JavaScript file, you will need to configure Webpack to use file-loader or url-loader to handle them. The project scaffolded with vue-cli has also configured this for you.

You can take a look at webpack.conf.js in order to see if it's well configured like

...
    {
        test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('img/[name].[hash:7].[ext]')
        }
      },
...

/assets is for files that are handles by webpack during bundling - for that, they have to be referenced somewhere in your javascript code.

Other assets can be put in /static, the content of this folder will be copied to /dist later as-is.

I recommend you to try to change:

iconUrl: './assets/img.png'

to

iconUrl: './dist/img.png'

You can read the official documentation here: https://vue-loader.vuejs.org/en/configurations/asset-url.html

Hope it helps to you!

True you can't have different sized slides. NOT true the size of you slide doesn't matter. It will size it to your resolution, but you can click on the magnifying icon(at least on PP 2013) and you can then scroll in all directions of your slide in original resolution.

if you have API level smaller than 23 than you must use it this way. it worked for me declare this under v21/style.

<item name="colorPrimaryDark" tools:targetApi="23">@color/colorPrimary</item>
        <item name="android:windowLightStatusBar" tools:targetApi="23">true</item>

Although this may be more complicated/heavier-weight than you want, one very flexible way to do it is using something like Expect (or one of the derivatives in another programming language).

Expect is a language designed specifically to control text-based applications, which is exactly what you are looking to do. If you end up needing to do something more complicated (like with logic to actually decide what to do/answer next), Expect is the way to go.

You can execute this in 2 simple statements:

row.names(samp) <- samp$names
samp[1] <- NULL

This worked for me.

self._name = name + '.mp4'
self._cap = VideoCapture(0)
self._fourcc = VideoWriter_fourcc(*'MP4V')
self._out = VideoWriter(self._name, self._fourcc, 20.0, (640,480))

Some databases are designed to communicate over the web using ports assigned by the Internet Assigned Number Authority (IANA) and when run on individual PC use the ports with localhost. Some common databases with their default ports (the defualts can usually be overridden):

Port Database

1433 Microsoft SQL Server https://support.microsoft.com/en-us/kb/287932

3306 MySQL https://dev.mysql.com/doc/refman/4.1/en/connecting.html

5432 PostgreSQL

1527 Apache Derby (database)

Some web servers and databases are paired together such as Apache/MySQL (as in LAMP or XXAMP) or MS Internet Information Server (IIS)/MS SQL Server (IIS/SQL Server) in which case you have to be concerned with both the port of the database and the web server -- a common example of this is WordPress which uses Apache/MySQL.

What language are you using?

Many C based languages have a rule that any mathematical expression is performed in size int or larger. Because of this, once you add two shorts the result is of type int. This causes the need for a cast.

Let say your html code is :

<input type="text" id="txtMyText" />

then the jquery should be :

$('#txtMyText').keyup(function() {
  this.value = this.value.toUpperCase();
});

Regarding tokens carrying information, JSON Web Tokens (http://jwt.io) is a brilliant technology. The main concept is to embed information elements (claims) into the token, and then signing the whole token so that the validating end can verify that the claims are indeed trustworthy.

I use this Java implementation: https://bitbucket.org/b_c/jose4j/wiki/Home

There is also a Spring module (spring-security-jwt), but I haven't looked into what it supports.

You can work on strings instead of numbers to achieve this. You can do it like this

(111 + '').split('')

This will return an array of strings ['1','1','1'] on which you can iterate upon and call parseInt method.

parseInt('1') === 1

If you want the sum of individual digits, you can use the reduce function (implemented from Javascript 1.8) like this

(111 + '').split('').reduce(function(previousValue, currentValue){  
  return parseInt(previousValue,10) + parseInt(currentValue,10);  
})

Your BigDecimal doesn't contain the number 10.0001, because you initialized it with a double, and the double didn't quite contain the number you thought it did. (This is the whole point of BigDecimal.)

If you use the string-based constructor instead:

BigDecimal bd = new BigDecimal("10.0001");

...then it will actually contain the number you expect.

Try:

expect(t).rejects.toThrow()

On CentOS with cPanel sudo /etc/init.d/crond reload does the trick.

On CentOS7: sudo systemctl start crond.service

Try importing this in build.gradle dependencies

compile group: 'com.googlecode.json-simple', name: 'json-simple', version: '1.1'

sudo apt-get remove docker docker-engine docker.io containerd runc
sudo rm -rf /var/lib/docker
sudo apt-get autoclean
sudo apt-get update

Use the Trim method.

Time.now.to_f can help you but it returns seconds.

In general, when working with benchmarks I:

• put in variable the current time;
• insert the block to test;
• put in a variable the current time, subtracting the preceding current-time value;

It's a very simple process, so I'm not sure you were really asking this...

I configured the app.config with the tool for EntLib configuration and set up my LoggingConfiguration block. Then I copied this into the DotNetConfig.xsd. Of course, it does not cover all attributes, only the ones I added but it does not display those annoying info messages anymore.

EDIT

I want to add the reason that your IF statement seems to not work. When you do an EXISTS on an aggregate, it's always going to be true. It returns a value even if the ID doesn't exist. Sure, it's NULL, but its returning it. Instead, do this:

if exists(select 1 from table where id = 4)

and you'll get to the ELSE portion of your IF statement.

Now, here's a better, set-based solution:

update b
  set code = isnull(a.value, 123)
from #b b
left join (select id, max(value) from #a group by id) a
  on b.id = a.id
where
  b.id = yourid

This has the benefit of being able to run on the entire table rather than individual ids.

Try this:

import pytz
import datetime

fmt = '%Y-%m-%d %H:%M:%S %Z'

d = datetime.datetime.now(pytz.timezone("America/New_York"))
d_string = d.strftime(fmt)
d2 = pytz.timezone('America/New_York').localize(d.strptime(d_string,fmt), is_dst=None)
print(d_string)
print(d2.strftime(fmt))

action attribute in <form method="post" action="action="""> should be just action=""

Passing a multidimensional array as argument to a function. Passing an one dim array as argument is more or less trivial. Let's take a look on more interesting case of passing a 2 dim array. In C you can't use a pointer to pointer construct (int **) instead of 2 dim array. Let's make an example:

void assignZeros(int(*arr)[5], const int rows) {
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < 5; j++) {
            *(*(arr + i) + j) = 0;
            // or equivalent assignment
            arr[i][j] = 0;
        }
    }

Here I have specified a function that takes as first argument a pointer to an array of 5 integers. I can pass as argument any 2 dim array that has 5 columns:

int arr1[1][5]
int arr1[2][5]
...
int arr1[20][5]
...

You may come to an idea to define a more general function that can accept any 2 dim array and change the function signature as follows:

void assignZeros(int ** arr, const int rows, const int cols) {
    for (int i = 0; i < rows; i++) {
        for (int j = 0; j < cols; j++) {
            *(*(arr + i) + j) = 0;
        }
    }
}

This code would compile but you will get a runtime error when trying to assign the values in the same way as in the first function. So in C a multidimensional arrays are not the same as pointers to pointers ... to pointers. An int(*arr)[5] is a pointer to array of 5 elements, an int(*arr)[6] is a pointer to array of 6 elements, and they are a pointers to different types!

Well, how to define functions arguments for higher dimensions? Simple, we just follow the pattern! Here is the same function adjusted to take an array of 3 dimensions:

void assignZeros2(int(*arr)[4][5], const int dim1, const int dim2, const int dim3) {
    for (int i = 0; i < dim1; i++) {
        for (int j = 0; j < dim2; j++) {
            for (int k = 0; k < dim3; k++) {
                *(*(*(arr + i) + j) + k) = 0;
                // or equivalent assignment
                arr[i][j][k] = 0;
            }
        }
    }
}

How you would expect, it can take as argument any 3 dim arrays that have in the second dimensions 4 elements and in the third dimension 5 elements. Anything like this would be OK:

arr[1][4][5]
arr[2][4][5]
...
arr[10][4][5]
...

But we have to specify all dimensions sizes up to the first one.

What you want is a SQL case statement. The form of these is either:

  select case [expression or column]
  when [value] then [result]
  when [value2] then [result2]
  else [value3] end

or:

  select case 
  when [expression or column] = [value] then [result]
  when [expression or column] = [value2] then [result2]
  else [value3] end

In your example you are after:

declare @temp as varchar(100)
set @temp='Measure'

select case @temp 
   when 'Measure' then Measure 
   else OtherMeasure end
from Measuretable
