Programs & Examples On #Memory limit

After enabling these two lines, it started working:

; Determines the size of the realpath cache to be used by PHP. This value should
; be increased on systems where PHP opens many files to reflect the quantity of
; the file operations performed.
; http://php.net/realpath-cache-size
realpath_cache_size = 16k

; Duration of time, in seconds for which to cache realpath information for a given
; file or directory. For systems with rarely changing files, consider increasing this
; value.
; http://php.net/realpath-cache-ttl
realpath_cache_ttl = 120

The memory must be configured in several places.
Set memory_limit to 512M:

sudo vi /etc/php5/cgi/php.ini
sudo vi /etc/php5/cli/php.ini
sudo vi /etc/php5/apache2/php.ini Or /etc/php5/fpm/php.ini

Restart service:

sudo service service php5-fpm restart
sudo service service nginx restart

or

sudo service apache2 restart

Finally it should solve the problem of the memory_limit

WordPress overrides PHP's memory limit to 256M, with the assumption that whatever it was set to before is going to be too low to render the dashboard. You can override this by defining WP_MAX_MEMORY_LIMIT in wp-config.php:

define( 'WP_MAX_MEMORY_LIMIT' , '512M' );

I agree with DanFromGermany, 256M is really a lot of memory for rendering a dashboard page. Changing the memory limit is really putting a bandage on the problem.

For the 1 GB RAM variant you can use a bit vector. You need to allocate 4 billion bits == 500 MB byte array. For each number you read from the input, set the corresponding bit to '1'. Once you done, iterate over the bits, find the first one that is still '0'. Its index is the answer.

I would suggest you are looking at the problem in the wrong light. The questtion should be 'what am i doing that needs 2G memory inside a apache process with Php via apache module and is this tool set best suited for the job?'

Yes you can strap a rocket onto a ford pinto, but it's probably not the right solution.

Regardless, I'll provide the rocket if you really need it... you can add to the top of the script.

ini_set('memory_limit','2048M');

This will set it for just the script. You will still need to tell apache to allow that much for a php script (I think).

very old post. but i'll just leave this here:

/* converts a number with byte unit (B / K / M / G) into an integer */
function unitToInt($s)
{
    return (int)preg_replace_callback('/(\-?\d+)(.?)/', function ($m) {
        return $m[1] * pow(1024, strpos('BKMG', $m[2]));
    }, strtoupper($s));
}

$mem_limit = unitToInt(ini_get('memory_limit'));

Doing :

ini_set('memory_limit', '-1');

is never good. If you want to read a very large file, it is a best practise to copy it bit by bit. Try the following code for best practise.

$path = 'path_to_file_.txt';

$file = fopen($path, 'r');
$len = 1024; // 1MB is reasonable for me. You can choose anything though, but do not make it too big
$output = fread( $file, $len );

while (!feof($file)) {
    $output .= fread( $file, $len );
}

fclose($file);

echo 'Output is: ' . $output;

Since you're using PHP, you will probably need to use the CURLOPT_PORT option, like so:

curl_setopt($ch, CURLOPT_PORT, 11740);

Bear in mind, you may face problems with SELinux:

Unable to make php curl request with port number

I found very nice solution. Microsoft released a beta version of Entity Framework Power Tools: Entity Framework Power Tools Beta 2

There you can generate POCO classes, derived DbContext and Code First mapping for an existing database in some clicks. It is very nice!

After installation some context menu options would be added to your Visual Studio.

Right-click on a C# project. Choose Entity Framework-> Reverse Engineer Code First (Generates POCO classes, derived DbContext and Code First mapping for an existing database):

Then choose your database and click OK. That's all! It is very easy.

Try out this simple solution, it worked for me

app.get('/', function(req, res){
    res.render('index.html')
  });

I know this is an old question, but just in case you are trying to do the same thing in ASP.NET Core, here is how you can create the UrlHelper inside an action:

var urlHelper = new UrlHelper(this.ControllerContext);

Or, you could just use the Controller.Url property if you inherit from Controller.

As you're making a synchronous request, that should be

function getRemote() {
    return $.ajax({
        type: "GET",
        url: remote_url,
        async: false
    }).responseText;
}

Example - http://api.jquery.com/jQuery.ajax/#example-3

PLEASE NOTE: Setting async property to false is deprecated and in the process of being removed (link). Many browsers including Firefox and Chrome have already started to print a warning in the console if you use this:

Chrome:

Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check https://xhr.spec.whatwg.org/.

Firefox:

Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help http://xhr.spec.whatwg.org/

When Python2.x sees a == b, it tries the following.

• If type(b) is a new-style class, and type(b) is a subclass of type(a), and type(b) has overridden __eq__, then the result is b.__eq__(a).
• If type(a) has overridden __eq__ (that is, type(a).__eq__ isn't object.__eq__), then the result is a.__eq__(b).
• If type(b) has overridden __eq__, then the result is b.__eq__(a).
• If none of the above are the case, Python repeats the process looking for __cmp__. If it exists, the objects are equal iff it returns zero.
• As a final fallback, Python calls object.__eq__(a, b), which is True iff a and b are the same object.

If any of the special methods return NotImplemented, Python acts as though the method didn't exist.

Note that last step carefully: if neither a nor b overloads ==, then a == b is the same as a is b.

From https://eev.ee/blog/2012/03/24/python-faq-equality/

As for the workaround (without using non-portable -P), you can temporary replace a new-line character with the different one and change it back, e.g.:

grep -o "_foo_" <(paste -sd_ file) | tr -d '_'

Basically it's looking for exact match _foo_ where _ means \n (so __ = \n\n). You don't have to translate it back by tr '_' '\n', as each pattern would be printed in the new line anyway, so removing _ is enough.

To find the last filled column use the following :

lastColumn = ActiveSheet.Cells(1, Columns.Count).End(xlToLeft).Column

If you know the folder you want to navigate to, find the index of it then substring.

            var ind = Directory.GetCurrentDirectory().ToString().IndexOf("Folderame");

            string productFolder = Directory.GetCurrentDirectory().ToString().Substring(0, ind);

You can do it using the Github API

This is the Python example:

import requests


if __name__ == '__main__':
    base_api_url = 'https://api.github.com/repos'
    git_repository_url = 'https://github.com/garysieling/wikipedia-categorization.git'

    github_username, repository_name = git_repository_url[:-4].split('/')[-2:]  # garysieling and wikipedia-categorization
    res = requests.get(f'{base_api_url}/{github_username}/{repository_name}')
    repository_size = res.json().get('size')
    print(repository_size)

You can use text classes:

.text-primary
.text-secondary
.text-success
.text-danger
.text-warning
.text-info
.text-light
.text-dark
.text-muted
.text-white

use text classes in any tag where needed.

<p class="text-primary">.text-primary</p>
<p class="text-secondary">.text-secondary</p>
<p class="text-success">.text-success</p>
<p class="text-danger">.text-danger</p>
<p class="text-warning">.text-warning</p>
<p class="text-info">.text-info</p>
<p class="text-light bg-dark">.text-light</p>
<p class="text-dark">.text-dark</p>
<p class="text-muted">.text-muted</p>
<p class="text-white bg-dark">.text-white</p>

You can add your own classes or modify above classes as your requirement.

Add set off also

 SET IDENTITY_INSERT Genre ON

    INSERT INTO Genre(Id, Name, SortOrder)VALUES (12,'Moody Blues', 20) 

    SET IDENTITY_INSERT Genre  OFF

A belated post:
Use the search regex pattern as a Record Separator (RS) in awk
This allows your regex to span \n-delimited lines (if you need it).

printf 'X \n moo X\n XX\n' | 
   awk -vRS='X[^X]*X' 'END{print (NR<2?0:NR-1)}'

Just for anyone trying to do this automatically, you can use that extension method to ignore non existing properties on the destination type :

public static IMappingExpression<TSource, TDestination> IgnoreAllNonExisting<TSource, TDestination>(this IMappingExpression<TSource, TDestination> expression)
{
    var sourceType = typeof(TSource);
    var destinationType = typeof(TDestination);
    var existingMaps = Mapper.GetAllTypeMaps().First(x => x.SourceType.Equals(sourceType)
        && x.DestinationType.Equals(destinationType));
    foreach (var property in existingMaps.GetUnmappedPropertyNames())
    {
        expression.ForMember(property, opt => opt.Ignore());
    }
    return expression;
}

to be used as follow :

Mapper.CreateMap<SourceType, DestinationType>().IgnoreAllNonExisting();

thanks to Can Gencer for the tip :)

If structure is flat:

val df = Seq((1L, "a", "foo", 3.0)).toDF
df.printSchema
// root
//  |-- _1: long (nullable = false)
//  |-- _2: string (nullable = true)
//  |-- _3: string (nullable = true)
//  |-- _4: double (nullable = false)

the simplest thing you can do is to use toDF method:

val newNames = Seq("id", "x1", "x2", "x3")
val dfRenamed = df.toDF(newNames: _*)

dfRenamed.printSchema
// root
// |-- id: long (nullable = false)
// |-- x1: string (nullable = true)
// |-- x2: string (nullable = true)
// |-- x3: double (nullable = false)

If you want to rename individual columns you can use either select with alias:

df.select($"_1".alias("x1"))

which can be easily generalized to multiple columns:

val lookup = Map("_1" -> "foo", "_3" -> "bar")

df.select(df.columns.map(c => col(c).as(lookup.getOrElse(c, c))): _*)

or withColumnRenamed:

df.withColumnRenamed("_1", "x1")

which use with foldLeft to rename multiple columns:

lookup.foldLeft(df)((acc, ca) => acc.withColumnRenamed(ca._1, ca._2))

With nested structures (structs) one possible option is renaming by selecting a whole structure:

val nested = spark.read.json(sc.parallelize(Seq(
    """{"foobar": {"foo": {"bar": {"first": 1.0, "second": 2.0}}}, "id": 1}"""
)))

nested.printSchema
// root
//  |-- foobar: struct (nullable = true)
//  |    |-- foo: struct (nullable = true)
//  |    |    |-- bar: struct (nullable = true)
//  |    |    |    |-- first: double (nullable = true)
//  |    |    |    |-- second: double (nullable = true)
//  |-- id: long (nullable = true)

@transient val foobarRenamed = struct(
  struct(
    struct(
      $"foobar.foo.bar.first".as("x"), $"foobar.foo.bar.first".as("y")
    ).alias("point")
  ).alias("location")
).alias("record")

nested.select(foobarRenamed, $"id").printSchema
// root
//  |-- record: struct (nullable = false)
//  |    |-- location: struct (nullable = false)
//  |    |    |-- point: struct (nullable = false)
//  |    |    |    |-- x: double (nullable = true)
//  |    |    |    |-- y: double (nullable = true)
//  |-- id: long (nullable = true)

Note that it may affect nullability metadata. Another possibility is to rename by casting:

nested.select($"foobar".cast(
  "struct<location:struct<point:struct<x:double,y:double>>>"
).alias("record")).printSchema

// root
//  |-- record: struct (nullable = true)
//  |    |-- location: struct (nullable = true)
//  |    |    |-- point: struct (nullable = true)
//  |    |    |    |-- x: double (nullable = true)
//  |    |    |    |-- y: double (nullable = true)

or:

import org.apache.spark.sql.types._

nested.select($"foobar".cast(
  StructType(Seq(
    StructField("location", StructType(Seq(
      StructField("point", StructType(Seq(
        StructField("x", DoubleType), StructField("y", DoubleType)))))))))
).alias("record")).printSchema

// root
//  |-- record: struct (nullable = true)
//  |    |-- location: struct (nullable = true)
//  |    |    |-- point: struct (nullable = true)
//  |    |    |    |-- x: double (nullable = true)
//  |    |    |    |-- y: double (nullable = true)

My way is to always Redirect::back() or Redirect::to():

Redirect::back()->with('message', 'error|There was an error...');

Redirect::back()->with('message', 'message|Record updated.');

Redirect::to('/')->with('message', 'success|Record updated.');

I have a helper function to make it work for me, usually this is in a separate service:

function displayAlert()
{
      if (Session::has('message'))
      {
         list($type, $message) = explode('|', Session::get('message'));

         $type = $type == 'error' : 'danger';
         $type = $type == 'message' : 'info';

         return sprintf('<div class="alert alert-%s">%s</div>', $type, message);
      }

      return '';
}

And in my view or layout I just do

{{ displayAlert() }}

People have mentioned make but bjam also supports a similar concept. Using bjam -jx instructs bjam to build up to x concurrent commands.

We use the same build scripts on Windows and Linux and using this option halves our build times on both platforms. Nice.

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.

>>> original = [('a', 1), ('b', 2), ('c', 3), ('d', 4)]
>>> tuple([list(tup) for tup in zip(*original)])
(['a', 'b', 'c', 'd'], [1, 2, 3, 4])

Gives a tuple of lists as in the question.

list1, list2 = [list(tup) for tup in zip(*original)]

Unpacks the two lists.

its simple let us assume you have made an state full class by extending Component which contains following

class DisableButton extends Components 
   {

      constructor()
       {
         super();
         // now set the initial state of button enable and disable to be false
          this.state = {isEnable: false }
       }

  // this function checks the length and make button to be enable by updating the state
     handleButtonEnable(event)
       {
         const value = this.target.value;
         if(value.length > 0 )
        {
          // set the state of isEnable to be true to make the button to be enable
          this.setState({isEnable : true})
        }


       }

      // in render you having button and input 
     render() 
       {
          return (
             <div>
                <input
                   placeholder={"ANY_PLACEHOLDER"}
                   onChange={this.handleChangePassword}

                  />

               <button 
               onClick ={this.someFunction}
               disabled = {this.state.isEnable} 
              /> 

             <div/>
            )

       }

   }

In case if you are under proxy environment and internet is not running in your emulator, then please don't change any setting in emulator. Go to your eclipse project, right click , click on "Run as" then click on "Run Configuration". In pop up window choose "Target" and scroll down a little, you will find "Additional Emulator Command Line Options" Enter your proxy setting here in "Additional Emulator Command Line Options" as i entered

-http-proxy http://ee11s040:[email protected]:3128

Then start a new Emulator.

            DirectoryInfo dirinfo = new DirectoryInfo(strMainPath);
            String[] exts = new string[] { "*.jpeg", "*.jpg", "*.gif", "*.tiff", "*.bmp","*.png", "*.JPEG", "*.JPG", "*.GIF", "*.TIFF", "*.BMP","*.PNG" };
            ArrayList files = new ArrayList();
            foreach (string ext in exts)
                files.AddRange(dirinfo.GetFiles(ext).OrderBy(x => x.CreationTime).ToArray());

If you are writing xml, just use the classes provided by the framework to create the xml. You won't have to bother with escaping or anything.

Console.Write(new XElement("Data", "< > &"));

Will output

<Data>&lt; &gt; &amp;</Data>

If you need to read an XML file that is malformed, do not use regular expression. Instead, use the Html Agility Pack.

here is another easier option

select to_number(column_value) as IDs from xmltable('1,2,3,4,5');

An actual JSON request would look like this:

data: '{"command":"on"}',

Where you're sending an actual JSON string. For a more general solution, use JSON.stringify() to serialize an object to JSON, like this:

data: JSON.stringify({ "command": "on" }),

To support older browsers that don't have the JSON object, use json2.js which will add it in.

What's currently happening is since you have processData: false, it's basically sending this: ({"command":"on"}).toString() which is [object Object]...what you see in your request.

yum install php-mbstring (as per http://php.net/manual/en/mbstring.installation.php)

I think you have to install the EPEL repository http://fedoraproject.org/wiki/EPEL

You can use Equals or CompareTo.

Equals: Returns a value indicating whether two DateTime instances have the same date and time value.

CompareTo Return Value:

1. Less than zero : If this instance is earlier than value.
2. Zero : If this instance is the same as value.
3. Greater than zero : If this instance is later than value.

DateTime is nullable:

DateTime? first = new DateTime(1992,02,02,20,50,1);
DateTime? second = new DateTime(1992, 02, 02, 20, 50, 2);

if (first.Value.Date.Equals(second.Value.Date))
{
    Console.WriteLine("Equal");
}

or

DateTime? first = new DateTime(1992,02,02,20,50,1);
DateTime? second = new DateTime(1992, 02, 02, 20, 50, 2);


var compare = first.Value.Date.CompareTo(second.Value.Date);

switch (compare)
{
    case 1:
        Console.WriteLine("this instance is later than value.");
        break;
    case 0:
        Console.WriteLine("this instance is the same as value.");
        break;
    default:
        Console.WriteLine("this instance is earlier than value.");
        break;
}

DateTime is not nullable:

DateTime first = new DateTime(1992,02,02,20,50,1);
DateTime second = new DateTime(1992, 02, 02, 20, 50, 2);

if (first.Date.Equals(second.Date))
{
    Console.WriteLine("Equal");
}

or

DateTime first = new DateTime(1992,02,02,20,50,1);
DateTime second = new DateTime(1992, 02, 02, 20, 50, 2);


var compare = first.Date.CompareTo(second.Date);

switch (compare)
{
    case 1:
        Console.WriteLine("this instance is later than value.");
        break;
    case 0:
        Console.WriteLine("this instance is the same as value.");
        break;
    default:
        Console.WriteLine("this instance is earlier than value.");
        break;
}

If you do not use Dates, functions, undefined, regExp or Infinity within your object, a very simple one liner is JSON.parse(JSON.stringify(object)):

const a = {_x000D_
  string: 'string',_x000D_
  number: 123,_x000D_
  bool: false,_x000D_
  nul: null,_x000D_
  date: new Date(),  // stringified_x000D_
  undef: undefined,  // lost_x000D_
  inf: Infinity,  // forced to 'null'_x000D_
}_x000D_
console.log(a);_x000D_
console.log(typeof a.date);  // Date object_x000D_
const clone = JSON.parse(JSON.stringify(a));_x000D_
console.log(clone);_x000D_
console.log(typeof clone.date);  // result of .toISOString()

This works for all kind of objects containing objects, arrays, strings, booleans and numbers.

See also this article about the structured clone algorithm of browsers which is used when posting messages to and from a worker. It also contains a function for deep cloning.

Since $("#selector").bind() is deprecated, you should use:

$("body").on('DOMSubtreeModified', "#selector", function() {
    // code here
});

Here is a simple if/else check in underscore.js, if you need to include a null check.

<div class="editor-label">
    <label>First Name : </label>
</div>
<div class="editor-field">
    <% if(FirstName == null) { %>
        <input type="text" id="txtFirstName" value="" />
    <% } else { %>
        <input type="text" id="txtFirstName" value="<%=FirstName%>" />
    <% } %>
</div>

There is also a shorthand of doing this:

NSArray *persons = @[person1, person2, person3];

It's equivalent to

NSArray *persons = [NSArray arrayWithObjects:person1, person2, person3, nil];

As iiFreeman said, you still need to do proper memory management if you're not using ARC.

You code should look like this:

public int getElement(int[] arrayOfInts, int index) {
    return arrayOfInts[index];
}

Main points here are method return type, it should match with array elements type and if you are working from main() - this method must be static also.

For better understand how it works!

int n = JOptionPane.showConfirmDialog(null, "Yes No Cancel", "YesNoCancel", JOptionPane.YES_NO_CANCEL_OPTION);
    if(n == 0)
        {
        JOptionPane.showConfirmDialog(null, "You pressed YES\n"+"Pressed value is = "+n);
        }
    else if(n == 1)
        {
        JOptionPane.showConfirmDialog(null, "You pressed NO\n"+"Pressed value is = "+n);
        }
    else if (n == 2)
        {
        JOptionPane.showConfirmDialog(null, "You pressed CANCEL\n"+"Pressed value is = "+n);
        }
    else if (n == -1)
        {
        JOptionPane.showConfirmDialog(null, "You pressed X\n"+"Pressed value is = "+n);
        }

OR

int n = JOptionPane.showConfirmDialog(null, "Yes No Cancel", "YesNoCancel", JOptionPane.YES_NO_CANCEL_OPTION);
    switch (n) {
        case 0:
            JOptionPane.showConfirmDialog(null, "You pressed YES\n"+"Pressed value is = "+n);
            break;
        case 1:
            JOptionPane.showConfirmDialog(null, "You pressed NO\n"+"Pressed value is = "+n);
            break;
        case 2:
            JOptionPane.showConfirmDialog(null, "You pressed CANCEL\n"+"Pressed value is = "+n);
            break;
        case -1:
            JOptionPane.showConfirmDialog(null, "You pressed X\n"+"Pressed value is = "+n);
            break;
        default:
            break;
    }

You can find that row with

DataRow row = table.Select("Product_id=2").FirstOrDefault();

and update it

row["Product_name"] = "cde";

In a standard context, each connected user holds an explorer.exe process: The command [tasklist /V|find "explorer"] returns a line that contains the explorer.exe process owner's, with an adapted regex it is possible to obtain the required value. This also runs perfectly under Windows 7.

In rare cases explorer.exe is replaced by another program, the find filter can be adapted to match this case. If the command return an empty line then it is likely that no user is logged on. With Windows 7 it is also possible to run [query session|find ">"].

Assuming SQL Server 2000, the following StackOverflow question should address your problem.

If using SQL Server 2005/2008, you can use the following code (taken from here):

select cast(replace(cast(myntext as nvarchar(max)),'find','replace') as ntext)
from myntexttable

Another native solution (in coffee):

el = document.getElementsByTagName 'b'

docFrag = document.createDocumentFragment()
docFrag.appendChild el.firstChild while el.childNodes.length

el.parentNode.replaceChild docFrag, el

I don't know if it's faster than user113716's solution, but it might be easier to understand for some.

You can use the data attribute:

In addition to the already posted answer, I thought I should share a handy trick I use to load all the DLL functions into the program through function pointers, without writing a separate GetProcAddress call for each and every function. I also like to call the functions directly as attempted in the OP.

Start by defining a generic function pointer type:

typedef int (__stdcall* func_ptr_t)();

What types that are used aren't really important. Now create an array of that type, which corresponds to the amount of functions you have in the DLL:

func_ptr_t func_ptr [DLL_FUNCTIONS_N];

In this array we can store the actual function pointers that point into the DLL memory space.

Next problem is that GetProcAddress expects the function names as strings. So create a similar array consisting of the function names in the DLL:

const char* DLL_FUNCTION_NAMES [DLL_FUNCTIONS_N] = 
{
  "dll_add",
  "dll_subtract",
  "dll_do_stuff",
  ...
};

Now we can easily call GetProcAddress() in a loop and store each function inside that array:

for(int i=0; i<DLL_FUNCTIONS_N; i++)
{
  func_ptr[i] = GetProcAddress(hinst_mydll, DLL_FUNCTION_NAMES[i]);

  if(func_ptr[i] == NULL)
  {
    // error handling, most likely you have to terminate the program here
  }
}

If the loop was successful, the only problem we have now is calling the functions. The function pointer typedef from earlier isn't helpful, because each function will have its own signature. This can be solved by creating a struct with all the function types:

typedef struct
{
  int  (__stdcall* dll_add_ptr)(int, int);
  int  (__stdcall* dll_subtract_ptr)(int, int);
  void (__stdcall* dll_do_stuff_ptr)(something);
  ...
} functions_struct;

And finally, to connect these to the array from before, create a union:

typedef union
{
  functions_struct  by_type;
  func_ptr_t        func_ptr [DLL_FUNCTIONS_N];
} functions_union;

Now you can load all the functions from the DLL with the convenient loop, but call them through the by_type union member.

But of course, it is a bit burdensome to type out something like

functions.by_type.dll_add_ptr(1, 1); whenever you want to call a function.

As it turns out, this is the reason why I added the "ptr" postfix to the names: I wanted to keep them different from the actual function names. We can now smooth out the icky struct syntax and get the desired names, by using some macros:

#define dll_add (functions.by_type.dll_add_ptr)
#define dll_subtract (functions.by_type.dll_subtract_ptr)
#define dll_do_stuff (functions.by_type.dll_do_stuff_ptr)

And voilà, you can now use the function names, with the correct type and parameters, as if they were statically linked to your project:

int result = dll_add(1, 1);

Disclaimer: Strictly speaking, conversions between different function pointers are not defined by the C standard and not safe. So formally, what I'm doing here is undefined behavior. However, in the Windows world, function pointers are always of the same size no matter their type and the conversions between them are predictable on any version of Windows I've used.

Also, there might in theory be padding inserted in the union/struct, which would cause everything to fail. However, pointers happen to be of the same size as the alignment requirement in Windows. A static_assert to ensure that the struct/union has no padding might be in order still.

I agree with Icarus (would have commented if I could), but instead of using a CustomObject class, I would use a Dictionary (in case Facebook adds something).

private class MyFacebookClass
{
    public IList<IDictionary<string, string>> data { get; set; }
}

or

private class MyFacebookClass
{
    public IList<IDictionary<string, object>> data { get; set; }
}

grep 'potato:' file.txt | sed 's/^.*: //'

grep looks for any line that contains the string potato:, then, for each of these lines, sed replaces (s/// - substitute) any character (.*) from the beginning of the line (^) until the last occurrence of the sequence : (colon followed by space) with the empty string (s/...// - substitute the first part with the second part, which is empty).

or

grep 'potato:' file.txt | cut -d\   -f2

For each line that contains potato:, cut will split the line into multiple fields delimited by space (-d\ - d = delimiter, \ = escaped space character, something like -d" " would have also worked) and print the second field of each such line (-f2).

or

grep 'potato:' file.txt | awk '{print $2}'

For each line that contains potato:, awk will print the second field (print $2) which is delimited by default by spaces.

or

grep 'potato:' file.txt | perl -e 'for(<>){s/^.*: //;print}'

All lines that contain potato: are sent to an inline (-e) Perl script that takes all lines from stdin, then, for each of these lines, does the same substitution as in the first example above, then prints it.

or

awk '{if(/potato:/) print $2}' < file.txt

The file is sent via stdin (< file.txt sends the contents of the file via stdin to the command on the left) to an awk script that, for each line that contains potato: (if(/potato:/) returns true if the regular expression /potato:/ matches the current line), prints the second field, as described above.

or

perl -e 'for(<>){/potato:/ && s/^.*: // && print}' < file.txt

The file is sent via stdin (< file.txt, see above) to a Perl script that works similarly to the one above, but this time it also makes sure each line contains the string potato: (/potato:/ is a regular expression that matches if the current line contains potato:, and, if it does (&&), then proceeds to apply the regular expression described above and prints the result).

SELECT 
(select count(*) from foo1 where ID = '00123244552000258')
+
(select count(*) from foo2 where ID = '00123244552000258')
+
(select count(*) from foo3 where ID = '00123244552000258')

This is an easy way.

The answer here worked better for me as it isolates the search on the hashtag, not just returning results that contain the search string. In the answer above you would still need to parse the JSON response to see if the entities.hashtags array is not empty.

You can use: if(-e $base_path)

MultiValueMap class

An instance variable is a variable that is a member of an instance of a class (i.e., associated with something created with a new), whereas a class variable is a member of the class itself.

Every instance of a class will have its own copy of an instance variable, whereas there is only one of each static (or class) variable, associated with the class itself.

What’s the difference between a class variable and an instance variable?

This test class illustrates the difference:

public class Test {
   
    public static String classVariable = "I am associated with the class";
    public String instanceVariable = "I am associated with the instance";
    
    public void setText(String string){
        this.instanceVariable = string;
    }
    
    public static void setClassText(String string){
        classVariable = string;
    }
    
    public static void main(String[] args) {
        Test test1 = new Test();
        Test test2 = new Test();
        
        // Change test1's instance variable
        test1.setText("Changed");
        System.out.println(test1.instanceVariable); // Prints "Changed"
        // test2 is unaffected
        System.out.println(test2.instanceVariable); // Prints "I am associated with the instance"
        
        // Change class variable (associated with the class itself)
        Test.setClassText("Changed class text");
        System.out.println(Test.classVariable); // Prints "Changed class text"
        
        // Can access static fields through an instance, but there still is only one
        // (not best practice to access static variables through instance)
        System.out.println(test1.classVariable); // Prints "Changed class text"
        System.out.println(test2.classVariable); // Prints "Changed class text"
    }
}

Don't know men. I found the best way for me after testing different ways like 10 minutes. ( Change the numbers in code to get big or small random number.)

    int x;
srand ( time(NULL) );
x = rand() % 1000 * rand() % 10000 ;
cout<<x;

I think the answer is pretty simple (unless I'm missing something?)

SELECT    
CASE
    WHEN col1 > col2 THEN SUM(col3*col4)
    ELSE 0
END AS some_product
FROM some_table
GROUP BY
CASE
    WHEN col1 > col2 THEN SUM(col3*col4)
    ELSE 0
END

You can put the CASE STATEMENT in the GROUP BY verbatim (minus the alias column name)

You need to use jQuery to do this. This approach gives you the abbility to have dynamic images and do them round no matter the size.

My demo has one flaw right now I don't center the image in the container, but ill return to it in a minute (need to finish a script I'm working on).

DEMO

<div class="container">
    <img src="" class="image" alt="lambo" />
</div>

//script
var container = $('.container'),
    image = container.find('img');

container.width(image.height());


//css    
.container {
    height: auto;
    overflow: hidden;
    border-radius: 50%;    
}

.image {
    height: 100%;    
    display: block;    
}

The way to solve this without knowing the width and the background color is the following:

Structure

<div class="strike">
   <span>Kringle</span>
</div>

CSS

.strike {
    display: block;
    text-align: center;
    overflow: hidden;
    white-space: nowrap; 
}

.strike > span {
    position: relative;
    display: inline-block;
}

.strike > span:before,
.strike > span:after {
    content: "";
    position: absolute;
    top: 50%;
    width: 9999px;
    height: 1px;
    background: red;
}

.strike > span:before {
    right: 100%;
    margin-right: 15px;
}

.strike > span:after {
    left: 100%;
    margin-left: 15px;
}

Example: http://jsfiddle.net/z8Hnz/

Double line

To create a double line, use one of the following options:

1) Fixed space between lines

.strike > span:before,
.strike > span:after {
    content: "";
    position: absolute;
    top: 50%;
    width: 9999px;
    border-top: 4px double red;

Example: http://jsfiddle.net/z8Hnz/103/

2) Custom space between lines

.strike > span:before,
.strike > span:after {
    content: "";
    position: absolute;
    top: 50%;
    width: 9999px;
    height: 5px; /* space between lines */
    margin-top: -2px; /* adjust vertical align */
    border-top: 1px solid red;
    border-bottom: 1px solid red;
}

Example: http://jsfiddle.net/z8Hnz/105/

SASS (SCSS) version

Based on this solution, I added SCSS "with color property" if it could help someone...

//mixins.scss
@mixin bg-strike($color) {

    display: block;
    text-align: center;
    overflow: hidden;
    white-space: nowrap; 

    > span {

        position: relative;
        display: inline-block;

        &:before,
        &:after {
            content: "";
            position: absolute;
            top: 50%;
            width: 9999px;
            height: 1px;
            background: $color;
        }

        &:before {
            right: 100%;
            margin-right: 15px;
        }

        &:after {
            left: 100%;
            margin-left: 15px;
        }
    }
}

example of use :

//content.scss
h2 {
    @include bg-strike($col1);
    color: $col1;
}

Here's another solution using the bin_data() function from the mltools package.

library(mltools)

# Resulting bins have an equal number of observations in each group
das[, "wt2"] <- bin_data(das$wt, bins=3, binType = "quantile")

# Resulting bins are equally spaced from min to max
das[, "wt3"] <- bin_data(das$wt, bins=3, binType = "explicit")

# Or if you'd rather define the bins yourself
das[, "wt4"] <- bin_data(das$wt, bins=c(-Inf, 250, 322, Inf), binType = "explicit")

das
   anim    wt                                  wt2                                  wt3         wt4

So there is another way you can actually fire it from any language. The best way I think, you can just create a batch file which will call your .dtsx package.

Next you call the batch file from any language. As in windows platform, you can run batch file from anywhere, I think this will be the most generic approach for your purpose. No code dependencies.

Below is a blog for more details..

Happy coding.. :)

Thanks, Ayan

The public keyword is used only when declaring a class method.

Since you're declaring a simple function and not a class you need to remove public from your code.

Actually, you dont really have to code to make the form get to centerscreen.

Just modify the properties of the jframe
Follow below steps to modify:

• right click on the form
• change FormSize policy to - generate resize code
• then edit the form position X -200 Y- 200

You're done. Why take the pain of coding. :)

From the Overview tab of jQuery autocomplete plugin:

The local data can be a simple Array of Strings, or it contains Objects for each item in the array, with either a label or value property or both. The label property is displayed in the suggestion menu. The value will be inserted into the input element after the user selected something from the menu. If just one property is specified, it will be used for both, eg. if you provide only value-properties, the value will also be used as the label.

So your "two-dimensional" array could look like:

var $local_source = [{
    value: 1,
    label: "c++"
}, {
    value: 2,
    label: "java"
}, {
    value: 3,
    label: "php"
}, {
    value: 4,
    label: "coldfusion"
}, {
    value: 5,
    label: "javascript"
}, {
    value: 6,
    label: "asp"
}, {
    value: 7,
    label: "ruby"
}];

You can access the label and value properties inside focus and select event through the ui argument using ui.item.label and ui.item.value.

Edit

Seems like you have to "cancel" the focus and select events so that it does not place the id numbers inside the text boxes. While doing so you can copy the value in a hidden variable instead. Here is an example.

pandas dataframe plot will return the ax for you, And then you can start to manipulate the axes whatever you want.

import pandas as pd
import numpy as np

df = pd.DataFrame(np.random.randn(100,5))

# you get ax from here
ax = df.plot()
type(ax)  # matplotlib.axes._subplots.AxesSubplot

# manipulate
vals = ax.get_yticks()
ax.set_yticklabels(['{:,.2%}'.format(x) for x in vals])

Let's assume you have a class like this:

public class Staff
{
    public int ID { get; set; }
    public string Name { get; set; }
}

And assume you have dragged and dropped a DataGridView to your form, and name it dataGridView1.

You need a BindingSource to hold your data to bind your DataGridView. This is how you can do it:

private void frmDGV_Load(object sender, EventArgs e)
{
    //dummy data
    List<Staff> lstStaff = new List<Staff>();
    lstStaff.Add(new Staff()
    {
        ID = 1,
        Name = "XX"
    });
    lstStaff.Add(new Staff()
    {
        ID = 2,
        Name = "YY"
    });

    //use binding source to hold dummy data
    BindingSource binding = new BindingSource();
    binding.DataSource = lstStaff;

    //bind datagridview to binding source
    dataGridView1.DataSource = binding;
}

In your manifest use:-

    android:theme="@style/AppTheme" >

in styles.xml:-

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
       <item name="android:windowActionBar">false</item>
   <item name="android:windowNoTitle">true</item>
</style>

Surprisingly this works as yo desire, Using the same parent of AppBaseTheme in AppTheme does not.

This line:

<input type="password" name="PasswordInput"/>

should have an id attribute, like so:

<input type="password" name="PasswordInput" id="PasswordInput"/>

Just add AsEnumerable() andToList() , so it looks like this

db.Favorites
    .Where(x => x.userId == userId)
    .Join(db.Person, x => x.personId, y => y.personId, (x, y).ToList().AsEnumerable()

ToList().AsEnumerable()

CSS flexbox can do it with justify-content: center on the image parent element. To preserve the aspect ratio of the image, add align-self: flex-start; to it.

HTML

<div class="image-container">
  <img src="http://placehold.it/100x100" />
</div>

CSS

.image-container {
  display: flex;
  justify-content: center;
}

Output:

body {_x000D_
  background: lightgray;_x000D_
}_x000D_

I hope I can make a useful supplement to this question. If your list stores a specific type object, for example Info, here is a situation that extend method is not suitable: In a for loop and and generating an Info object every time and using extend to store it into your list, it will fail. The exception is like below:

TypeError: 'Info' object is not iterable

But if you use the append method, the result is OK. Because every time using the extend method, it will always treat it as a list or any other collection type, iterate it, and place it after the previous list. A specific object can not be iterated, obviously.

When using Maven with IntelliJ IDE you can add -Djavax.xml.accessExternalSchema=all to Maven setting under JVM Options for Maven Build Tools Runner configuration

From http://www.coderanch.com/t/236675/java-programmer-SCJP/certification/xff

The hex literal 0xFF is an equal int(255). Java represents int as 32 bits. It look like this in binary:

00000000 00000000 00000000 11111111

When you do a bit wise AND with this value(255) on any number, it is going to mask(make ZEROs) all but the lowest 8 bits of the number (will be as-is).

... 01100100 00000101 & ...00000000 11111111 = 00000000 00000101

& is something like % but not really.

And why 0xff? this in ((power of 2) - 1). All ((power of 2) - 1) (e.g 7, 255...) will behave something like % operator.

Then
In binary, 0 is, all zeros, and 255 looks like this:

00000000 00000000 00000000 11111111

And -1 looks like this

11111111 11111111 11111111 11111111

When you do a bitwise AND of 0xFF and any value from 0 to 255, the result is the exact same as the value. And if any value higher than 255 still the result will be within 0-255.

However, if you do:

-1 & 0xFF

you get

00000000 00000000 00000000 11111111, which does NOT equal the original value of -1 (11111111 is 255 in decimal).

Few more bit manipulation: (Not related to the question)

X >> 1 = X/2
X << 1 = 2X

Check any particular bit is set(1) or not (0) then

 int thirdBitTobeChecked =   1 << 2   (...0000100)
 int onWhichThisHasTobeTested = 5     (.......101)

 int isBitSet = onWhichThisHasTobeTested  & thirdBitTobeChecked;
 if(isBitSet > 0) {
  //Third Bit is set to 1 
 } 

Set(1) a particular bit

 int thirdBitTobeSet =   1 << 2    (...0000100)
 int onWhichThisHasTobeSet = 2     (.......010)
 onWhichThisHasTobeSet |= thirdBitTobeSet;

ReSet(0) a particular bit

int thirdBitTobeReSet =   ~(1 << 2)  ; //(...1111011)
int onWhichThisHasTobeReSet = 6      ;//(.....000110)
onWhichThisHasTobeReSet &= thirdBitTobeReSet;

XOR

Just note that if you perform XOR operation twice, will results the same value.

byte toBeEncrypted = 0010 0110
byte salt          = 0100 1011

byte encryptedVal  =  toBeEncrypted ^ salt == 0110 1101
byte decryptedVal  =  encryptedVal  ^ salt == 0010 0110 == toBeEncrypted :)

One more logic with XOR is

if     A (XOR) B == C (salt)
then   C (XOR) B == A
       C (XOR) A == B

The above is useful to swap two variables without temp like below

a = a ^ b; b = a ^ b; a = a ^ b;

OR

a ^= b ^= a ^= b;

React uses value instead of selected for consistency across the form components. You can use defaultValue to set an initial value. If you're controlling the value, you should set value as well. If not, do not set value and instead handle the onChange event to react to user action.

Note that value and defaultValue should match the value of the option.

This is what you have to do

var fileVariable =document.getElementsById('fileId').files[0];

If you want to check for image file types then

if(fileVariable.type.match('image.*'))
{
 alert('its an image');
}

For those who don't want to create any models, use the following code:

var result = JsonConvert.DeserializeObject<
  List<Dictionary<string, 
    Dictionary<string, string>>>>(content);

Note: This doesn't work for your JSON string. This is not a general solution for any JSON structure.

You can view which modules (compiled in) are available via terminal through php -m

I'm just gonna through another code example in the basket

from glob import glob

with open('singleDataFile.csv', 'a') as singleFile:
    for csvFile in glob('*.csv'):
        for line in open(csvFile, 'r'):
            singleFile.write(line)

In GDB 7.2:

(gdb) help info proc
Show /proc process information about any running process.
Specify any process id, or use the program being debugged by default.
Specify any of the following keywords for detailed info:
  mappings -- list of mapped memory regions.
  stat     -- list a bunch of random process info.
  status   -- list a different bunch of random process info.
  all      -- list all available /proc info.

You want info proc mappings, except it doesn't work when there is no /proc (such as during pos-mortem debugging).

Try maintenance info sections instead.

I do this using the TextMaskModule from 'angular2-text-mask'

Mine are split but you can get the idea

Package using NPM NodeJS

"dependencies": {
    "angular2-text-mask": "8.0.0",

HTML

<input *ngIf="column?.type =='areaCode'" type="text" [textMask]="{mask: areaCodeMask}" [(ngModel)]="areaCodeModel">


<input *ngIf="column?.type =='phone'" type="text" [textMask]="{mask: phoneMask}" [(ngModel)]="phoneModel"> 

Inside Component

public areaCodeModel = '';
public areaCodeMask = ['(', /[1-9]/, /\d/, /\d/, ')'];

public phoneModel = '';
public phoneMask = [/\d/, /\d/, /\d/, '-', /\d/, /\d/, /\d/, /\d/];

I would prefer the C++ min/max functions, if you are using C++, because they are type-specific. fmin/fmax will force everything to be converted to/from floating point.

Also, the C++ min/max functions will work with user-defined types as long as you have defined operator< for those types.

Top comment has a broken link to the console.log documentation for Firebug, so here is a link to the wiki article about Console. I started using it and am quite satisfied with it as an alternative to PHP's print_r().

Also of note is that Firebug gives you access to returned JSON objects even without you manually logging them:

• In the console you can see the url of the AJAX response.
• Click the triangle to expand the response and see details.
• Click the JSON tab in the details.
• You will see the response data organized with expansion triangles.

This method take a couple more clicks to get at the data but doesn't require any additions in your actual javascript and doesn't shift your focus in Firebug out of the console (using console.log creates a link to the DOM section of firebug, forcing you to click back to console after).

For my money I'd rather click a couple more times when I want to inspect rather than mess around with the log, especially since keeps the console neat by not adding any additional cruft.

just check the directory structure where exactly image is suppose you have a css folder and images folder outside css folder then you will have to use"../images/image.jpg" and it will work as it did for me just make sure the directory stucture.

If you get an error involving index.android.js. This is because you are using the new React-native version (I am using 0.55.4) Just replace the "index.android.js" to "index.js"

react-native bundle --platform android --dev false --entry-file index.js   --bundle-output android/app/src/main/assets/index.android.bundle   --assets-dest android/app/src/main/res/

You can do it with vim stdin and stdout. You can also use ex to be POSIX compliant. vim is just the visual mode for ex. In fact, you can use ex with vim -e or vim -E (improved ex mode). vim is useful because unlike tools like sed it buffers the file for editing, while sed is used for streams. You might be able to use awk, but you would have to manually buffer everything in a variable.

The idea is to do the following:

1. Read from stdin
2. For each line move it to line 1 (to reverse). Command is g/^/m0. This means globally, for each line g; match the start of the line, which matches anything ^; move it after address 0, which is line 1 m0.
3. Print everything. Command is %p. This means for the range of all lines %; print the line p.
4. Forcefully quit without saving the file. Command is q!. This means quit q; forcefully !.

How to make this reusable

I use a script I call ved (vim editor like sed) to use vim to edit stdin. Add this to a file called ved in your path:

#!/usr/bin/env sh

vim - --not-a-term -Es "$@" +'%p | q!'

I am using one + command instead of +'%p' +'q!', because vim limits you to 10 commands. So merging them allows the "$@" to have 9 + commands instead of 8.

Then you can do:

seq 10 | ved +'g/^/m0'

If you don't have vim 8, put this in ved instead:

#!/usr/bin/env sh

vim -E "$@" +'%p | q!' /dev/stdin

There are a few ways that a file path can be represented. You should use the System.IO.Path class to get the separators for the OS, since it can vary between UNIX and Windows. Also, most (or all if I'm not mistaken) .NET libraries accept either a '\' or a '/' as a path separator, regardless of OS. For this reason, I'd use the Path class to split your paths. Try something like the following:

string originalPath = "\\server\\folderName1\\another\ name\\something\\another folder\\";
string[] filesArray = originalPath.Split(Path.AltDirectorySeparatorChar,
                              Path.DirectorySeparatorChar);

This should work regardless of the number of folders or the names.

String message = URLEncoder.encode("my message", "UTF-8");

try {

    // Closes this output stream and releases any system resources
    // associated with this stream. At this point, we've sent all the

    // stuff in the first if block
    if (connection.getResponseCode() == HttpURLConnection.HTTP_OK) {
        // OK

        // otherwise, if any other status code is returned, or no status
        // code is returned, do stuff in the else block
    } else {
        // Server returned HTTP error code.
    }
} catch (MalformedURLException e) {
    // ...
} catch (IOException e) {
    // ...
}

The first 3 answers to your questions are listed as inline comments, beside each method, in the example HTTP POST above.

From getOutputStream:

Returns an output stream that writes to this connection.

Basically, I think you have a good understanding of how this works, so let me just reiterate in layman's terms. getOutputStream basically opens a connection stream, with the intention of writing data to the server. In the above code example "message" could be a comment that we're sending to the server that represents a comment left on a post. When you see getOutputStream, you're opening the connection stream for writing, but you don't actually write any data until you call writer.write("message=" + message);.

From getInputStream():

Returns an input stream that reads from this open connection. A SocketTimeoutException can be thrown when reading from the returned input stream if the read timeout expires before data is available for read.

getInputStream does the opposite. Like getOutputStream, it also opens a connection stream, but the intent is to read data from the server, not write to it. If the connection or stream-opening fails, you'll see a SocketTimeoutException.

How about the getInputStream? Since I'm only able to get the response at getInputStream, then does it mean that I didn't send any request at getOutputStream yet but simply establishes a connection?

Keep in mind that sending a request and sending data are two different operations. When you invoke getOutputStream or getInputStream url.openConnection(), you send a request to the server to establish a connection. There is a handshake that occurs where the server sends back an acknowledgement to you that the connection is established. It is then at that point in time that you're prepared to send or receive data. Thus, you do not need to call getOutputStream to establish a connection open a stream, unless your purpose for making the request is to send data.

In layman's terms, making a getInputStream request is the equivalent of making a phone call to your friend's house to say "Hey, is it okay if I come over and borrow that pair of vice grips?" and your friend establishes the handshake by saying, "Sure! Come and get it". Then, at that point, the connection is made, you walk to your friend's house, knock on the door, request the vice grips, and walk back to your house.

Using a similar example for getOutputStream would involve calling your friend and saying "Hey, I have that money I owe you, can I send it to you"? Your friend, needing money and sick inside that you kept it for so long, says "Sure, come on over you cheap bastard". So you walk to your friend's house and "POST" the money to him. He then kicks you out and you walk back to your house.

Now, continuing with the layman's example, let's look at some Exceptions. If you called your friend and he wasn't home, that could be a 500 error. If you called and got a disconnected number message because your friend is tired of you borrowing money all the time, that's a 404 page not found. If your phone is dead because you didn't pay the bill, that could be an IOException. (NOTE: This section may not be 100% correct. It's intended to give you a general idea of what's happening in layman's terms.)

Question #5:

Yes, you are correct that openConnection simply creates a new connection object but does not establish it. The connection is established when you call either getInputStream or getOutputStream.

openConnection creates a new connection object. From the URL.openConnection javadocs:

A new connection is opened every time by calling the openConnection method of the protocol handler for this URL.

The connection is established when you call openConnection, and the InputStream, OutputStream, or both, are called when you instantiate them.

Question #6:

To measure the overhead, I generally wrap some very simple timing code around the entire connection block, like so:

long start = System.currentTimeMillis();
log.info("Time so far = " + new Long(System.currentTimeMillis() - start) );

// run the above example code here
log.info("Total time to send/receive data = " + new Long(System.currentTimeMillis() - start) );

I'm sure there are more advanced methods for measuring the request time and overhead, but this generally is sufficient for my needs.

For information on closing connections, which you didn't ask about, see In Java when does a URL connection close?.

Awhile ago, I put together a package for doing what you want, and more. (I needed it for a utility I was writing). It uses the ASM library. You can use reflection, but ASM turned out to perform better.

I put my package in an open source library I have on my web site. The library is here: http://software.clapper.org/javautil/. You want to start with the with ClassFinder class.

The utility I wrote it for is an RSS reader that I still use every day, so the code does tend to get exercised. I use ClassFinder to support a plug-in API in the RSS reader; on startup, it looks in a couple directory trees for jars and class files containing classes that implement a certain interface. It's a lot faster than you might expect.

The library is BSD-licensed, so you can safely bundle it with your code. Source is available.

If that's useful to you, help yourself.

Update: If you're using Scala, you might find this library to be more Scala-friendly.

One way, using regular expressions:

>>> s = "how much for the maple syrup? $20.99? That's ridiculous!!!"
>>> re.sub(r'[^\w]', ' ', s)
'how much for the maple syrup   20 99  That s ridiculous   '

• \w will match alphanumeric characters and underscores

• [^\w] will match anything that's not alphanumeric or underscore

You can use the TelephonyManager to do this:

TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE); 
String number = tm.getLine1Number();

The documentation for getLine1Number() says this method will return null if the number is "unavailable", but it does not say when the number might be unavailable.

You'll need to give your application permission to make this query by adding the following to your Manifest:

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

(You shouldn't use TelephonyManager.getDefault() to get the TelephonyManager as that is a private undocumented API call and may change in future.)

First of all, there are still browsers out there that don't support those pseudo-elements (ie. :first-child, :last-child), so you have to 'deal' with this issue.

There is a good example how to make that work without using pseudo-elements:

http://www.darowski.com/tracesofinspiration/2010/01/11/this-newbies-first-impressions-of-haml-and-sass/

       -- see the divider pipe example.

I hope that was useful.

When can I realistically except to observe a performance improvement after using noexcept? In particular, give an example of code for which a C++ compiler is able to generate better machine code after the addition of noexcept.

Um, never? Is never a time? Never.

noexcept is for compiler performance optimizations in the same way that const is for compiler performance optimizations. That is, almost never.

noexcept is primarily used to allow "you" to detect at compile-time if a function can throw an exception. Remember: most compilers don't emit special code for exceptions unless it actually throws something. So noexcept is not a matter of giving the compiler hints about how to optimize a function so much as giving you hints about how to use a function.

Templates like move_if_noexcept will detect if the move constructor is defined with noexcept and will return a const& instead of a && of the type if it is not. It's a way of saying to move if it is very safe to do so.

In general, you should use noexcept when you think it will actually be useful to do so. Some code will take different paths if is_nothrow_constructible is true for that type. If you're using code that will do that, then feel free to noexcept appropriate constructors.

In short: use it for move constructors and similar constructs, but don't feel like you have to go nuts with it.

To test whether a file itself has ACL_EXECUTE bit set in any of permission sets (user, group, others) regardless of where it resides, i. e. even on a tmpfs with noexec option, use stat -c '%A' to get the permission string and then check if it contains at least a single “x” letter:

if [[ "$(stat -c '%A' 'my_exec_file')" == *'x'* ]] ; then
    echo 'Has executable permission for someone'
fi

The right-hand part of comparison may be modified to fit more specific cases, such as *x*x*x* to check whether all kinds of users should be able to execute the file when it is placed on a volume mounted with exec option.

Use Loaded event:

private void cmb_Loaded(object sender, RoutedEventArgs e) {
    if (cmb.Items.Count > 0) cmb.SelectedIndex = 0;          
}

It works for me.

You may also try this:

arrOfObj.forEach(function(item){item.isActive = true;});

console.log(arrOfObj);

Is there a reason why you aren't using a table variable and the aggregate SUM operator, instead of a cursor? SQL excels at set-oriented operations. 99.87% of the time that you find yourself using a cursor, there's a set-oriented alternative that's more efficient:

declare @MonthsSale table
(
MonthNumber int,
MonthName varchar(9),
MonthSale decimal(18,2)
)

insert into @MonthsSale
select
    1, 'January', 100.00
union select    
    2, 'February', 200.00
union select    
    3, 'March', 300.00
union select    
    4, 'April', 400.00
union select    
    5, 'May', 500.00
union select    
    6, 'June', 600.00
union select    
    7, 'July', 700.00
union select    
    8, 'August', 800.00
union select    
    9, 'September', 900.00
union select    
    10, 'October', 1000.00
union select    
    11, 'November', 1100.00
union select    
    12, 'December', 1200.00

select * from @MonthsSale   
select SUM(MonthSale) as [TotalSales] from @MonthsSale

You can also get specific index using

curl -X GET "localhost:9200/<INDEX_NAME>"
e.g.   curl -X GET "localhost:9200/twitter"
You may get output like:
{
  "twitter": {
     "aliases": { 

     },
     "mappings": { 

     },
     "settings": {
     "index": {
        "creation_date": "1540797250479",
        "number_of_shards": "3",
        "number_of_replicas": "2",
        "uuid": "CHYecky8Q-ijsoJbpXP95w",
        "version": {
            "created": "6040299"
        },
       "provided_name": "twitter"
      }
    }
  }
}

Why not look to the RFC that currently defines Base64?

Base encoding of data is used in many situations to store or transfer
data in environments that, perhaps for legacy reasons, are restricted to US-ASCII [1] data.Base encoding can also be used in new applications that do not have legacy restrictions, simply because it makes it possible to manipulate objects with text editors.

In the past, different applications have had different requirements and thus sometimes implemented base encodings in slightly different ways. Today, protocol specifications sometimes use base encodings in general, and "base64" in particular, without a precise description or reference. Multipurpose Internet Mail Extensions (MIME) [4] is often used as a reference for base64 without considering the consequences for line-wrapping or non-alphabet characters. The purpose of this specification is to establish common alphabet and encoding considerations. This will hopefully reduce ambiguity in other documents, leading to better interoperability.

Base64 was originally devised as a way to allow binary data to be attached to emails as a part of the Multipurpose Internet Mail Extensions.

        // Necessary if your app targets Marshmallow (since Espresso
        // hasn't moved to Marshmallow yet)
        exclude group: 'com.android.support', module: 'support-annotations'
    }
    androidTestCompile('com.android.support.test:runner:0.5') {

        // hasn't moved to Marshmallow yet)
        exclude group: 'com.android.support', module: 'support-annotations'
    }
}

I've added that to my gradle file and the warning disappeared.

Also, if you get any other dependency listed as conflicting, such as support-annotations, try excluding it too from the androidTestCompile dependencies.

If you would like to ignore case you could use the following:

String s = "yip";
String best = "yodel";
int compare = s.compareToIgnoreCase(best);
if(compare < 0){
    //-1, --> s is less than best. ( s comes alphabetically first)
}
else if(compare > 0 ){
// best comes alphabetically first.
}
else{
    // strings are equal.
}

Use this one, I've written this to my app,

<?xml version="1.0" encoding="utf-8"?>
<!--  res/drawable/rounded_edittext.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" android:padding="10dp">
    <solid android:color="#882C383E"/>
    <corners
        android:bottomRightRadius="5dp"
        android:bottomLeftRadius="5dp"
        android:topLeftRadius="5dp"
        android:topRightRadius="5dp"/>
</shape>

public function store( UserStoreRequest $request ) {
    $input = $request->all();
    $user = User::create($input);
    $userId=$user->id 
}

How about this one?

SELECT TO_CHAR(ASOFDATE, 'YYYY') FROM PSASOFDATE

In C++11, the using keyword when used for type alias is identical to typedef.

7.1.3.2

A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.

Bjarne Stroustrup provides a practical example:

typedef void (*PFD)(double);    // C style typedef to make `PFD` a pointer to a function returning void and accepting double
using PF = void (*)(double);    // `using`-based equivalent of the typedef above
using P = [](double)->void; // using plus suffix return type, syntax error
using P = auto(double)->void // Fixed thanks to DyP

Pre-C++11, the using keyword can bring member functions into scope. In C++11, you can now do this for constructors (another Bjarne Stroustrup example):

class Derived : public Base { 
public: 
    using Base::f;    // lift Base's f into Derived's scope -- works in C++98
    void f(char);     // provide a new f 
    void f(int);      // prefer this f to Base::f(int) 

    using Base::Base; // lift Base constructors Derived's scope -- C++11 only
    Derived(char);    // provide a new constructor 
    Derived(int);     // prefer this constructor to Base::Base(int) 
    // ...
}; 

Ben Voight provides a pretty good reason behind the rationale of not introducing a new keyword or new syntax. The standard wants to avoid breaking old code as much as possible. This is why in proposal documents you will see sections like Impact on the Standard, Design decisions, and how they might affect older code. There are situations when a proposal seems like a really good idea but might not have traction because it would be too difficult to implement, too confusing, or would contradict old code.

Here is an old paper from 2003 n1449. The rationale seems to be related to templates. Warning: there may be typos due to copying over from PDF.

First let’s consider a toy example:

template <typename T>
class MyAlloc {/*...*/};

template <typename T, class A>
class MyVector {/*...*/};

template <typename T>

struct Vec {
typedef MyVector<T, MyAlloc<T> > type;
};
Vec<int>::type p; // sample usage

The fundamental problem with this idiom, and the main motivating fact for this proposal, is that the idiom causes the template parameters to appear in non-deducible context. That is, it will not be possible to call the function foo below without explicitly specifying template arguments.

template <typename T> void foo (Vec<T>::type&);

So, the syntax is somewhat ugly. We would rather avoid the nested ::type We’d prefer something like the following:

template <typename T>
using Vec = MyVector<T, MyAlloc<T> >; //defined in section 2 below
Vec<int> p; // sample usage

Note that we specifically avoid the term “typedef template” and introduce the new syntax involving the pair “using” and “=” to help avoid confusion: we are not defining any types here, we are introducing a synonym (i.e. alias) for an abstraction of a type-id (i.e. type expression) involving template parameters. If the template parameters are used in deducible contexts in the type expression then whenever the template alias is used to form a template-id, the values of the corresponding template parameters can be deduced – more on this will follow. In any case, it is now possible to write generic functions which operate on Vec<T> in deducible context, and the syntax is improved as well. For example we could rewrite foo as:

template <typename T> void foo (Vec<T>&);

We underscore here that one of the primary reasons for proposing template aliases was so that argument deduction and the call to foo(p) will succeed.

The follow-up paper n1489 explains why using instead of using typedef:

It has been suggested to (re)use the keyword typedef — as done in the paper [4] — to introduce template aliases:

template<class T> 
    typedef std::vector<T, MyAllocator<T> > Vec;

That notation has the advantage of using a keyword already known to introduce a type alias. However, it also displays several disavantages among which the confusion of using a keyword known to introduce an alias for a type-name in a context where the alias does not designate a type, but a template; Vec is not an alias for a type, and should not be taken for a typedef-name. The name Vec is a name for the family std::vector< [bullet] , MyAllocator< [bullet] > > – where the bullet is a placeholder for a type-name. Consequently we do not propose the “typedef” syntax. On the other hand the sentence

template<class T>
    using Vec = std::vector<T, MyAllocator<T> >;

can be read/interpreted as: from now on, I’ll be using Vec<T> as a synonym for std::vector<T, MyAllocator<T> >. With that reading, the new syntax for aliasing seems reasonably logical.

I think the important distinction is made here, aliases instead of types. Another quote from the same document:

An alias-declaration is a declaration, and not a definition. An alias- declaration introduces a name into a declarative region as an alias for the type designated by the right-hand-side of the declaration. The core of this proposal concerns itself with type name aliases, but the notation can obviously be generalized to provide alternate spellings of namespace-aliasing or naming set of overloaded functions (see ? 2.3 for further discussion). [My note: That section discusses what that syntax can look like and reasons why it isn't part of the proposal.] It may be noted that the grammar production alias-declaration is acceptable anywhere a typedef declaration or a namespace-alias-definition is acceptable.

Summary, for the role of using:

• template aliases (or template typedefs, the former is preferred namewise)
• namespace aliases (i.e., namespace PO = boost::program_options and using PO = ... equivalent)
• the document says A typedef declaration can be viewed as a special case of non-template alias-declaration. It's an aesthetic change, and is considered identical in this case.
• bringing something into scope (for example, namespace std into the global scope), member functions, inheriting constructors

It cannot be used for:

int i;
using r = i; // compile-error

Instead do:

using r = decltype(i);

Naming a set of overloads.

// bring cos into scope
using std::cos;

// invalid syntax
using std::cos(double);

// not allowed, instead use Bjarne Stroustrup function pointer alias example
using test = std::cos(double);

"Java SE8 for Programmers" claims that the Java will cope with either. (pp. 480, last paragraph). The example claims that:

c:\Program Files\Java\jdk1.6.0_11\demo/jfc

will parse just fine. Take note of the last (Unix-style) separator.

It's tacky, and probably error-prone, but it is what they (Deitel and Deitel) claim.

I think the confusion for people, rather than Java, is reason enough not to use this (mis?)feature.

This is due because of the items id being the same. On change fires only if a different item id is detected on select.

So you have 2 options: First is to make sure that each items have a unique id when retrieving datas from ajax.

Second is to trigger a rand number at formatSelection for the selected item.

function getRandomInt(min, max) {
    return Math.floor(Math.random() * (max - min + 1)) + min;
}

.

formatSelection: function(item) {item.id =getRandomInt(1,200)}

Quite easy... You're doing it wrong, because by that event the control is not there:

protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow && 
        (e.Row.RowState & DataControlRowState.Edit) == DataControlRowState.Edit)
    { 
        // Here you will get the Control you need like:
        DropDownList dl = (DropDownList)e.Row.FindControl("ddlPBXTypeNS");
    }
}

That is, it will only be valid for a DataRow (the actually row with data), and if it's in Edit mode... because you only edit one row at a time. The e.Row.FindControl("ddlPBXTypeNS") will only find the control that you want.

I wrote this awhile back. It assumes the delimiter is a comma and that the individual values aren't bigger than 127 characters. It could be modified pretty easily.

It has the benefit of not being limited to 4,000 characters.

Good luck!

Use ::ng-deep with caution. I used it throughout my app to set the material design toolbar color to different colors throughout my app only to find that when the app was in testing the toolbar colors step on each other. Come to find out it is because these styles becomes global, see this article Here is a working code solution that doesn't bleed into other components.

<mat-toolbar #subbar>
...
</mat-toolbar>

export class BypartSubBarComponent implements AfterViewInit {
  @ViewChild('subbar', { static: false }) subbar: MatToolbar;
  constructor(
    private renderer: Renderer2) { }
  ngAfterViewInit() {
    this.renderer.setStyle(
      this.subbar._elementRef.nativeElement, 'backgroundColor', 'red');
  }

}

this is possible with jQuery $.ajax() method

$.ajax(serverUrl, {
   type: OutageViewModel.Id() == 0 ? "POST" : "PUT",
   data: dataToSave,
   statusCode: {
      200: function (response) {
         alert('1');
         AfterSavedAll();
      },
      201: function (response) {
         alert('1');
         AfterSavedAll();
      },
      400: function (response) {
         alert('1');
         bootbox.alert('<span style="color:Red;">Error While Saving Outage Entry Please Check</span>', function () { });
      },
      404: function (response) {
         alert('1');
         bootbox.alert('<span style="color:Red;">Error While Saving Outage Entry Please Check</span>', function () { });
      }
   }, success: function () {
      alert('1');
   },
});

If you were asking how to get the PID of a known command it would resemble something like this:

If you had issued the command below #The command issued was ***

dd if=/dev/diskx of=/dev/disky

Then you would use:

PIDs=$(ps | grep dd | grep if | cut -b 1-5)

What happens here is it pipes all needed unique characters to a field and that field can be echoed using

echo $PIDs

"Dino TW" has provided the link to the comment Hibernate Mapping Exception : Repeated column in mapping for entity which has the vital information.

The link hints to provide "inverse=true" in the set mapping, I tried it and it actually works. It is such a rare situation wherein a Set and Composite key come together. Make inverse=true, we leave the insert & update of the table with Composite key to be taken care by itself.

Below can be the required mapping,

<class name="com.example.CompanyEntity" table="COMPANY">
    <id name="id" column="COMPANY_ID"/>
    <set name="names" inverse="true" table="COMPANY_NAME" cascade="all-delete-orphan" fetch="join" batch-size="1" lazy="false">
        <key column="COMPANY_ID" not-null="true"/>
        <one-to-many entity-name="vendorName"/>
    </set>
</class>

For me, on Yosemite

$ brew install mcrypt php56-mcrypt

restart computer

did the trick.

Long story short,
IQueryable is designed to postpone RUN process and firstly build the expression in conjunction with other IQueryable expressions, and then interprets and runs the expression as a whole.
But ToList() method (or a few sort of methods like that), are ment to run the expression instantly "as is".
Your first method (GetAllUrlsAsync), will run imediately, because it is IQueryable followed by ToListAsync() method. hence it runs instantly (asynchronous), and returns a bunch of IEnumerables.
Meanwhile your second method (GetAllUrls), won't get run. Instead, it returns an expression and CALLER of this method is responsible to run the expression.

This problem can also happen in Windows. Cmake looks into the registry and sometimes python values are not set. For those with similar problem:

http://ericsilva.org/2012/10/11/restoring-your-python-registry-in-windows/

Just create a .reg file to set the necessary keys and edit accordingly to match your setup.

@vimal answer did not provide solution for me. It seems the orientation is not the current orientation, but from previous orientation. To fix it, I use [[UIDevice currentDevice] orientation]

- (void)orientationChanged:(NSNotification *)notification{
    [self adjustViewsForOrientation:[[UIDevice currentDevice] orientation]];
}

Then

- (void) adjustViewsForOrientation:(UIDeviceOrientation) orientation { ... }

With this code I get the current orientation position.

In you app config file change the url to localhost/example/public

Then when you want to link to something

<a href="{{ url('page') }}">Some Text</a>

without blade

<a href="<?php echo url('page') ?>">Some Text</a>

define('SECONDS_PER_DAY', 86400);
$days_ago = date('Y-m-d', time() - 5 * SECONDS_PER_DAY);

Other than that, you can use strtotime for any date:

$days_ago = date('Y-m-d', strtotime('January 18, 2034') - 5 * SECONDS_PER_DAY);

Or, as you used, mktime:

$days_ago = date('Y-m-d', mktime(0, 0, 0, 12, 2, 2008) - 5 * SECONDS_PER_DAY);

Well, you get it. The key is to remove enough seconds from the timestamp.

$(document).ready(function() {
    $(".tab").click(function () {
        if(!$(this).hasClass('active'))
        {
            $(".tab.active").removeClass("active");
            $(this).addClass("active");        
        }
    });
});

There are several issues here.

1. You can't assign DataContext as DataContext="{Binding Employee}" because it's a complex object which can't be assigned as string. So you have to use <Window.DataContext></Window.DataContext> syntax.
2. You assign the class that represents the data context object to the view, not an individual property so {Binding Employee} is invalid here, you just have to specify an object.
3. Now when you assign data context using valid syntax like below

   <Window.DataContext>
      <local:Employee/>
   </Window.DataContext>

know that you are creating a new instance of the Employee class and assigning it as the data context object. You may well have nothing in default constructor so nothing will show up. But then how do you manage it in code behind file? You have typecast the DataContext.

    private void my_button_Click(object sender, RoutedEventArgs e)
    {
        Employee e = (Employee) DataContext;
    }

4. A second way is to assign the data context in the code behind file itself. The advantage then is your code behind file already knows it and can work with it.

   public partial class MainWindow : Window
   {
      Employee employee = new Employee();
   
      public MainWindow()
      {
          InitializeComponent();
   
          DataContext = employee;
      }
   }
   

Base-64 encoding is a way of taking binary data and turning it into text so that it's more easily transmitted in things like e-mail and HTML form data.

    <script>

        // Instantiate your javascript function
        niceJavascriptRoutine = null;

        // Begin jQuery
        $(document).ready(function() {

            // Your jQuery function
            function niceJqueryRoutine() {
                // some code
            }
            // Point the javascript function to the jQuery function
            niceJavaScriptRoutine = niceJueryRoutine;

        });

This worked for me to stop silly work breaks from happening within Chrome textareas

Iterate through the loop using the value in a dynamic selector that utilizes the attribute selector.

var values="Test,Prof,Off";
$.each(values.split(","), function(i,e){
    $("#strings option[value='" + e + "']").prop("selected", true);
});

Working Example http://jsfiddle.net/McddQ/1/

nodeName is the attribute you are looking for. For example:

var elt = document.getElementById('foo');
console.log(elt.nodeName);

Note that nodeName returns the element name capitalized and without the angle brackets, which means that if you want to check if an element is an <div> element you could do it as follows:

elt.nodeName == "DIV"

While this would not give you the expected results:

elt.nodeName == "<div>"

Below is the easiest way in case if Anaconda is already installed.

1) Under "Files", there is an option called,"Upload".

2) Click on "Upload" button and it asks for the path of the file and select the file and click on upload button present beside the file.

A more up to date answer for anyone else who comes across this:

(from https://www.jetbrains.com/help/idea/eclipse.html, §Auto-compilation; click for screenshots)

Compile automatically:

To enable automatic compilation, navigate to Settings/Preferences | Build, Execution, Deployment | Compiler and select the Build project automatically option

Show all errors in one place:

The Problems tool window appears if the Make project automatically option is enabled in the Compiler settings. It shows a list of problems that were detected on project compilation.

Use the Eclipse compiler: This is actually bundled in IntelliJ. It gives much more useful error messages, in my opinion, and, according to this blog, it's much faster since it was designed to run in the background of an IDE and uses incremental compilation.

While Eclipse uses its own compiler, IntelliJ IDEA uses the javac compiler bundled with the project JDK. If you must use the Eclipse compiler, navigate to Settings/Preferences | Build, Execution, Deployment | Compiler | Java Compiler and select it... The biggest difference between the Eclipse and javac compilers is that the Eclipse compiler is more tolerant to errors, and sometimes lets you run code that doesn't compile.

In case anyone else is stuck with this: it just means the write permissions are wrong in the repo that you’re pushing to. Go and chmod -R it so that the user you’re accessing the git server with has write access.

http://blog.shamess.info/2011/05/06/remote-rejected-na-unpacker-error/

It just works.

You can use FusedLocationProvider

For using Fused Location Provider in your project you will have to add the google play services location dependency in our app level build.gradle file

dependencies {
   implementation fileTree(dir: 'libs', include: ['*.jar'])
   ...
   ...
   ...
   implementation 'com.google.android.gms:play-services-location:17.0.0'
}

Permissions in Manifest

Apps that use location services must request location permissions. Android offers two location permissions: ACCESS_COARSE_LOCATION and ACCESS_FINE_LOCATION.

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

As you may know that from Android 6.0 (Marshmallow) you must request permissions for important access in the runtime. Cause it’s a security issue where while installing an application, user may not clearly understand about an important permission of their device.

ActivityCompat.requestPermissions(
    this,
    arrayOf(Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_FINE_LOCATION),
    PERMISSION_ID
)

Then you can use the FusedLocationProvider Client to get the updated location in your desired place.

    mFusedLocationClient.lastLocation.addOnCompleteListener(this) { task ->
        var location: Location? = task.result
        if (location == null) {
            requestNewLocationData()
        } else {
            findViewById<TextView>(R.id.latTextView).text = location.latitude.toString()
            findViewById<TextView>(R.id.lonTextView).text = location.longitude.toString()
        }
    }

You can also check certain configuration like if the device has location settings on or not. You can also check the article on Detect Current Latitude & Longitude using Kotlin in Android for more functionality. If there is no cache location then it will catch the current location using:

private fun requestNewLocationData() {
    var mLocationRequest = LocationRequest()
    mLocationRequest.priority = LocationRequest.PRIORITY_HIGH_ACCURACY
    mLocationRequest.interval = 0
    mLocationRequest.fastestInterval = 0
    mLocationRequest.numUpdates = 1

    mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this)
    mFusedLocationClient!!.requestLocationUpdates(
            mLocationRequest, mLocationCallback,
            Looper.myLooper()
    )
}

try this in javascript

 document.getElementById("22IdMObileFull").text ="itsClicked"

Why not just

$(".commentArea").keypress(function(e) {
    var textVal = $(this).val();
    if(e.which == 13 && e.shiftKey) {

    }
    else if (e.which == 13) {
       e.preventDefault(); //Stops enter from creating a new line
       this.form.submit(); //or ajax submit
    }
});

Edit: Use printf("val = 0x%" PRIx64 "\n", val); instead.

Try printf("val = 0x%llx\n", val);. See the printf manpage:

ll (ell-ell). A following integer conversion corresponds to a long long int or unsigned long long int argument, or a following n conversion corresponds to a pointer to a long long int argument.

Edit: Even better is what @M_Oehm wrote: There is a specific macro for that, because unit64_t is not always a unsigned long long: PRIx64 see also this stackoverflow answer

Let me preface this by saying I'm talking primarily about method access here, and to a slightly lesser extent, marking classes final, not member access.

The old wisdom

"mark it private unless you have a good reason not to"

made sense in days when it was written, before open source dominated the developer library space and VCS/dependency mgmt. became hyper collaborative thanks to Github, Maven, etc. Back then there was also money to be made by constraining the way(s) in which a library could be utilized. I spent probably the first 8 or 9 years of my career strictly adhering to this "best practice".

Today, I believe it to be bad advice. Sometimes there's a reasonable argument to mark a method private, or a class final but it's exceedingly rare, and even then it's probably not improving anything.

Have you ever:

• Been disappointed, surprised or hurt by a library etc. that had a bug that could have been fixed with inheritance and few lines of code, but due to private / final methods and classes were forced to wait for an official patch that might never come? I have.
• Wanted to use a library for a slightly different use case than was imagined by the authors but were unable to do so because of private / final methods and classes? I have.
• Been disappointed, surprised or hurt by a library etc. that was overly permissive in it's extensibility? I have not.

These are the three biggest rationalizations I've heard for marking methods private by default:

Rationalization #1: It's unsafe and there's no reason to override a specific method

I can't count the number of times I've been wrong about whether or not there will ever be a need to override a specific method I've written. Having worked on several popular open source libs, I learned the hard way the true cost of marking things private. It often eliminates the only practical solution to unforseen problems or use cases. Conversely, I've never in 16+ years of professional development regretted marking a method protected instead of private for reasons related to API safety. When a developer chooses to extend a class and override a method, they are consciously saying "I know what I'm doing." and for the sake of productivity that should be enough. period. If it's dangerous, note it in the class/method Javadocs, don't just blindly slam the door shut.

Marking methods protected by default is a mitigation for one of the major issues in modern SW development: failure of imagination.

Rationalization #2: It keeps the public API / Javadocs clean

This one is more reasonable, and depending on the target audience it might even be the right thing to do, but it's worth considering what the cost of keeping the API "clean" actually is: extensibility. For the reasons mentioned above, it probably makes more sense to mark things protected by default just in case.

Rationalization #3: My software is commercial and I need to restrict it's use.

This is reasonable too, but as a consumer I'd go with the less restrictive competitor (assuming no significant quality differences exist) every time.

Never say never

I'm not saying never mark methods private. I'm saying the better rule of thumb is to "make methods protected unless there's a good reason not to".

This advice is best suited for those working on libraries or larger scale projects that have been broken into modules. For smaller or more monolithic projects it doesn't tend to matter as much since you control all the code anyway and it's easy to change the access level of your code if/when you need it. Even then though, I'd still give the same advice :-)

The other answers don't work for me. I'm trying to get the command line working in Jenkins. All you need are the following command line arguments:

--non-interactive

--trust-server-cert

If you have multiple projects in your git repo, .idea/workspace.xml will not match to any files.

Instead, do the following:

$ git rm -f **/.idea/workspace.xml

And make your .gitignore look something like this:

# User-specific stuff:
**/.idea/workspace.xml
**/.idea/tasks.xml
**/.idea/dictionaries
**/.idea/vcs.xml
**/.idea/jsLibraryMappings.xml

# Sensitive or high-churn files:
**/.idea/dataSources.ids
**/.idea/dataSources.xml
**/.idea/dataSources.local.xml
**/.idea/sqlDataSources.xml
**/.idea/dynamic.xml
**/.idea/uiDesigner.xml

## File-based project format:
*.iws

# IntelliJ
/out/

Well, those features are specific to a tool that you are using for development in those languages.

You wouldn't have those tools if (for example) you were using notepad to write code. So, maybe you should ask the question for the tool you are using.

For PHP: http://webservices.xml.com/pub/a/ws/2004/03/24/phpws.html

you need implements Parcelable in your ContactBean class, I put one example for you:

public class ContactClass implements Parcelable {

private String id;
private String photo;
private String firstname;
private String lastname;

public ContactClass()
{

}

private ContactClass(Parcel in) {
    firstname = in.readString();
    lastname = in.readString();
    photo = in.readString();
    id = in.readString();

}

@Override
public int describeContents() {
    // TODO Auto-generated method stub
    return 0;
}

@Override
public void writeToParcel(Parcel dest, int flags) {

    dest.writeString(firstname);
    dest.writeString(lastname);
    dest.writeString(photo);
    dest.writeString(id);

}

 public static final Parcelable.Creator<ContactClass> CREATOR = new Parcelable.Creator<ContactClass>() {
        public ContactClass createFromParcel(Parcel in) {
            return new ContactClass(in);
        }

        public ContactClass[] newArray(int size) {
            return new ContactClass[size];

        }
    };

   // all get , set method 
 }

and this get and set for your code:

Intent intent = new Intent(this,DisplayContact.class);
intent.putExtra("Contact_list", ContactLis);
startActivity(intent);

second class:

ArrayList<ContactClass> myList = getIntent().getParcelableExtra("Contact_list");

brew help will show you the list of commands that are available.

brew list will show you the list of installed packages. You can also append formulae, for example brew list postgres will tell you of files installed by postgres (providing it is indeed installed).

brew search <search term> will list the possible packages that you can install. brew search post will return multiple packages that are available to install that have post in their name.

brew info <package name> will display some basic information about the package in question.

You can also search http://searchbrew.com or https://brewformulas.org (both sites do basically the same thing)

The SaveFileDialog control won't do any saving at all. All it does is providing you a convenient interface to actually display Windows' default file save dialog.

1. Set the property InitialDirectory to the drive you'd like it to show some other default. Just think of other computers that might have a different layout. By default windows will save the directory used the last time and present it again.

2. That is handled outside the control. You'll have to check the dialog's results and then do the saving yourself (e.g. write a text or binary file).

Just as a quick example (there are alternative ways to do it). savefile is a control of type SaveFileDialog

SaveFileDialog savefile = new SaveFileDialog(); 
// set a default file name
savefile.FileName = "unknown.txt";
// set filters - this can be done in properties as well
savefile.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*";

if (savefile.ShowDialog() == DialogResult.OK)
{
    using (StreamWriter sw = new StreamWriter(savefile.FileName))
        sw.WriteLine ("Hello World!");
}

Something like this should work:

INSERT INTO #IMEIS (imei) VALUES ('val1'), ('val2'), ...

UPDATE:

Apparently this syntax is only available starting on SQL Server 2008.

Server Tomcat v7.0 Server at localhost failed to start.

This error resolve following three case

1.Clean project & server

Or

2.Remove .snap file from this directory

<workspace-directory>\.metadata\.plugins\org.eclipse.core.resources

Or

3.Remove temp file from this directory

<workspace-directory>\.metadata\.plugins\org.eclipse.wst.server.core

How about the following?

First ask the user for the number of rows and columns, store that in say, nrows and ncols (i.e. scanf("%d", &nrows);) and then allocate memory for a 2D array of size nrows x ncols. Thus you can have a matrix of a size specified by the user, and not fixed at some dimension you've hardcoded!

Then store the elements with for(i = 0;i < nrows; ++i) ... and display the elements in the same way except you throw in newlines after every row, i.e.

for(i = 0; i < nrows; ++i)
{
   for(j = 0; j < ncols ; ++j) 
   {
      printf("%d\t",mat[i][j]);
   }
printf("\n");
}

Building on the other answers I've written this helper that accomplishes the task, including example usage:

public static class Helper
{
    public static List<T> RawSqlQuery<T>(string query, Func<DbDataReader, T> map)
    {
        using (var context = new DbContext())
        {
            using (var command = context.Database.GetDbConnection().CreateCommand())
            {
                command.CommandText = query;
                command.CommandType = CommandType.Text;

                context.Database.OpenConnection();

                using (var result = command.ExecuteReader())
                {
                    var entities = new List<T>();

                    while (result.Read())
                    {
                        entities.Add(map(result));
                    }

                    return entities;
                }
            }
        }
    }

Usage:

public class TopUser
{
    public string Name { get; set; }

    public int Count { get; set; }
}

var result = Helper.RawSqlQuery(
    "SELECT TOP 10 Name, COUNT(*) FROM Users U"
    + " INNER JOIN Signups S ON U.UserId = S.UserId"
    + " GROUP BY U.Name ORDER BY COUNT(*) DESC",
    x => new TopUser { Name = (string)x[0], Count = (int)x[1] });

result.ForEach(x => Console.WriteLine($"{x.Name,-25}{x.Count}"));

I plan to get rid of it as soon as built-in support is added. According to a statement by Arthur Vickers from the EF Core team it is a high priority for post 2.0. The issue is being tracked here.

If you are using hadoop 2.* API there are more elegant solutions:

    Configuration conf = getConf();
    Job job = Job.getInstance(conf);
    FileSystem fs = FileSystem.get(conf);

    //the second boolean parameter here sets the recursion to true
    RemoteIterator<LocatedFileStatus> fileStatusListIterator = fs.listFiles(
            new Path("path/to/lib"), true);
    while(fileStatusListIterator.hasNext()){
        LocatedFileStatus fileStatus = fileStatusListIterator.next();
        //do stuff with the file like ...
        job.addFileToClassPath(fileStatus.getPath());
    }

DEMO : http://jsfiddle.net/shfj70qp/

//dd/mm/yyyy 

var date = new Date();
var month = date.getMonth();
var day = date.getDate();
var year = date.getFullYear();

console.log(month+"/"+day+"/"+year);

While we are talking about STL, maps and dictionary, I'd recommend taking a look at the C5 library. It offers several types of dictionaries and maps that I've frequently found useful (along with many other interesting and useful data structures).

If you are a C++ programmer moving to C# as I did, you'll find this library a great resource (and a data structure for this dictionary).

Have a look at Cassini. This is basically what Visual Studio uses for its built-in debug web server. I've used it with Umbraco and it seems quite good.

Solution working with different types and with upper and lower cases.
For example, without the toLowerCase statement, "Goodyear" will come before "doe" with an ascending sort. Run the code snippet at the bottom of my answer to view the different behaviors.

JSON DATA:

var people = [
{
    "f_name" : "john",
    "l_name" : "doe", // lower case
    "sequence": 0 // int
},
{
    "f_name" : "michael",
    "l_name" : "Goodyear", // upper case
    "sequence" : 1 // int
}];

JSON Sort Function:

function sortJson(element, prop, propType, asc) {
  switch (propType) {
    case "int":
      element = element.sort(function (a, b) {
        if (asc) {
          return (parseInt(a[prop]) > parseInt(b[prop])) ? 1 : ((parseInt(a[prop]) < parseInt(b[prop])) ? -1 : 0);
        } else {
          return (parseInt(b[prop]) > parseInt(a[prop])) ? 1 : ((parseInt(b[prop]) < parseInt(a[prop])) ? -1 : 0);
        }
      });
      break;
    default:
      element = element.sort(function (a, b) {
        if (asc) {
          return (a[prop].toLowerCase() > b[prop].toLowerCase()) ? 1 : ((a[prop].toLowerCase() < b[prop].toLowerCase()) ? -1 : 0);
        } else {
          return (b[prop].toLowerCase() > a[prop].toLowerCase()) ? 1 : ((b[prop].toLowerCase() < a[prop].toLowerCase()) ? -1 : 0);
        }
      });
  }
}

I was having the same issue while adding a mapbox navigation API and resolved this issue by going to: file>project Structure and then setting the compile sdk version and build tool version to the latest. And here is the screenshot:

Hope it helps.

This is how I use OUTPUT INSERTED, when inserting to a table that uses ID as identity column in SQL Server:

'myConn is the ADO connection, RS a recordset and ID an integer
Set RS=myConn.Execute("INSERT INTO M2_VOTELIST(PRODUCER_ID,TITLE,TIMEU) OUTPUT INSERTED.ID VALUES ('Gator','Test',GETDATE())")
ID=RS(0)

I think you maybe need a service to store file upload and get that file. Check more detail from here

1) Create a Storage Sevice

@Service
public class StorageService {

Logger log = LoggerFactory.getLogger(this.getClass().getName());
private final Path rootLocation = Paths.get("upload-dir");

public void store(MultipartFile file) {
    try {
        Files.copy(file.getInputStream(), this.rootLocation.resolve(file.getOriginalFilename()));
    } catch (Exception e) {
        throw new RuntimeException("FAIL!");
    }
}

public Resource loadFile(String filename) {
    try {
        Path file = rootLocation.resolve(filename);
        Resource resource = new UrlResource(file.toUri());
        if (resource.exists() || resource.isReadable()) {
            return resource;
        } else {
            throw new RuntimeException("FAIL!");
        }
    } catch (MalformedURLException e) {
        throw new RuntimeException("FAIL!");
    }
}

public void deleteAll() {
    FileSystemUtils.deleteRecursively(rootLocation.toFile());
}

public void init() {
    try {
        Files.createDirectory(rootLocation);
    } catch (IOException e) {
        throw new RuntimeException("Could not initialize storage!");
    }
}
}

2) Create Rest Controller to upload and get file

@Controller
public class UploadController {

@Autowired
StorageService storageService;

List<String> files = new ArrayList<String>();

@PostMapping("/post")
public ResponseEntity<String> handleFileUpload(@RequestParam("file") MultipartFile file) {
    String message = "";
    try {
        storageService.store(file);
        files.add(file.getOriginalFilename());

        message = "You successfully uploaded " + file.getOriginalFilename() + "!";
        return ResponseEntity.status(HttpStatus.OK).body(message);
    } catch (Exception e) {
        message = "FAIL to upload " + file.getOriginalFilename() + "!";
        return      ResponseEntity.status(HttpStatus.EXPECTATION_FAILED).body(message);
    }
}

@GetMapping("/getallfiles")
public ResponseEntity<List<String>> getListFiles(Model model) {
    List<String> fileNames = files
            .stream().map(fileName -> MvcUriComponentsBuilder
                    .fromMethodName(UploadController.class, "getFile", fileName).build().toString())
            .collect(Collectors.toList());

    return ResponseEntity.ok().body(fileNames);
}

@GetMapping("/files/{filename:.+}")
@ResponseBody
public ResponseEntity<Resource> getFile(@PathVariable String filename) {
    Resource file = storageService.loadFile(filename);
    return ResponseEntity.ok()
            .header(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=\"" + file.getFilename() + "\"")
            .body(file);
}

}

I'm unsing ubuntu 14.04

Below command solved this problem for me.

sudo apt-get install php-mysql

In my case, after updating my php version from 5.5.9 to 7.0.8 i received this error including two other errors.

errors:

1. laravel/framework v5.2.14 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.

2. phpunit/phpunit 4.8.22 requires ext-dom * -> the requested PHP extension dom is missing from your system.

3. [PDOException]
   could not find driver

Solutions:

I installed this packages and my problems are gone.

sudo apt-get install php-mbstring

sudo apt-get install php-xml

sudo apt-get install php-mysql

For most software that isn't actually string-processing software, program logic ought not to depend on the content of string variables. Whenever I see something like this in a program:

if (s == "value")

I get a bad feeling. Why is there a string literal in this method? What's setting s? Does it know that logic depends on the value of the string? Does it know that it has to be lower case to work? Should I be fixing this by changing it to use String.Compare? Should I be creating an Enum and parsing into it?

From this perspective, one gets to a philosophy of code that's pretty simple: you avoid examining a string's contents wherever possible. Comparing a string to String.Empty is really just a special case of comparing it to a literal: it's something to avoid doing unless you really have to.

Knowing this, I don't blink when I see something like this in our code base:

string msg = Validate(item);
if (msg != null)
{
   DisplayErrorMessage(msg);
   return;
}

I know that Validate would never return String.Empty, because we write better code than that.

Of course, the rest of the world doesn't work like this. When your program is dealing with user input, databases, files, and so on, you have to account for other philosophies. There, it's the job of your code to impose order on chaos. Part of that order is knowing when an empty string should mean String.Empty and when it should mean null.

(Just to make sure I wasn't talking out of my ass, I just searched our codebase for `String.IsNullOrEmpty'. All 54 occurrences of it are in methods that process user input, return values from Python scripts, examine values retrieved from external APIs, etc.)

This setting goes in your web.config file. It affects the entire application, though... I don't think you can set it per page.

    <httpRuntime maxRequestLength="xxx" />

"xxx" is in KB. The default is 4096 (= 4 MB).

For Workbench 6.0

Open MySql workbench. To take database backup you need to create New Server Instance(If not available) within Server Administration.

Steps to Create New Server Instance:

1. Select New Server Instance option within Server Administrator.
2. Provide connection details.

After creating new server instance , it will be available in Server Administration list. Double click on Server instance you have created OR Click on Manage Import/Export option and Select Server Instance.

Now, From DATA EXPORT/RESTORE select DATA EXPORT option,Select Schema and Schema Object for backup.

You can take generate backup file in different way as given below-

Q.1) Backup file(.sql) contains both Create Table statements and Insert into Table Statements

ANS:

1. Select Start Export Option

Q.2) Backup file(.sql) contains only Create Table Statements, not Insert into Table statements for all tables

ANS:

1. Select Skip Table Data(no-data) option

2. Select Start Export Option

Q.3) Backup file(.sql) contains only Insert into Table Statements, not Create Table statements for all tables

ANS:

1. Select Advance Option Tab, Within Tables Panel- select no-create info-Do not write CREATE TABLE statement that re-create each dumped table option.
2. Select Start Export Option

For Workbench 6.3

1. Click on Management tab at left side in Navigator Panel
2. Click on Data Export Option
3. Select Schema
4. Select Tables
5. Select required option from dropdown below the tables list as per your requirement
6. Select Include Create schema checkbox
7. Click on Advance option
8. Select Complete insert checkbox in Inserts Panel
9. Start Export

For Workbench 8.0

1. Go to Server tab
2. Go to Database Export

This opens up something like this

3. Select the schema to export in the Tables to export
4. Click on Export to Self-Contained file
5. Check if Advanced Options... are exactly as you want the export
6. Click the button Start Export

The option -C works; just for clarification I'll post 2 examples:

1. creation of a tarball without the full path: full path /home/testuser/workspace/project/application.war and what we want is just project/application.war so:

   tar -cvf output_filename.tar  -C /home/testuser/workspace project
   

   Note: there is a space between workspace and project; tar will replace full path with just project .

2. extraction of tarball with changing the target path (default to ., i.e current directory)

   tar -xvf output_filename.tar -C /home/deploy/
   

   tar will extract tarball based on given path and preserving the creation path; in our example the file application.war will be extracted to /home/deploy/project/application.war.

   /home/deploy: given on extract
   project: given on creation of tarball

Note : if you want to place the created tarball in a target directory, you just add the target path before tarball name. e.g.:

tar -cvf /path/to/place/output_filename.tar  -C /home/testuser/workspace project

You are getting ORA-12560: TNS:protocol adaptor error becuase you didn't start the Oracle database.

You can start Oracle database like this. From START-> select Oracle Database 11g Express Edition( 11g or what ever your database type.you can find this from All Programs). Then inside this folder there is a DB icon with green color spot. It is the Start Service icon.Click it.Then it will take some seconds and start the service.

After getting the above message,again try to connect through the SQL plus command line by giving user name and password.

It is possible to build an arbitrary GET or POST request and send it to any server accessible to a victims browser. This includes devices on your local network, such as Printers and Routers.

There are many ways of building a CSRF exploit. A simple POST based CSRF attack can be sent using .submit() method. More complex attacks, such as cross-site file upload CSRF attacks will exploit CORS use of the xhr.withCredentals behavior.

CSRF does not violate the Same-Origin Policy For JavaScript because the SOP is concerned with JavaScript reading the server's response to a clients request. CSRF attacks don't care about the response, they care about a side-effect, or state change produced by the request, such as adding an administrative user or executing arbitrary code on the server.

Make sure your requests are protected using one of the methods described in the OWASP CSRF Prevention Cheat Sheet. For more information about CSRF consult the OWASP page on CSRF.

Most common AD default design is to have a container, cn=users just after the root of the domain. Thus a DN might be:

cn=admin,cn=users,DC=domain,DC=company,DC=com

Also, you might have sufficient rights in an LDAP bind to connect anonymously, and query for (cn=admin). If so, you should get the full DN back in that query.

I was trying to set up MediaWiki on my windows 7 pc and got this error.

My solution was to "create a global FastCGI handler mapping for php".

You can use a 3rd party library like Shield UI for charting - that is tested and works well on all legacy and new web browsers and devices.

Try

if (isset($_POST['fromPerson']) && $_POST['fromPerson'] != "") {
    echo "Cool";
}

I started with @jhoff's solution, but rewrote it to use width/height parameters, and using arcTo makes it quite a bit more terse:

CanvasRenderingContext2D.prototype.roundRect = function (x, y, w, h, r) {
  if (w < 2 * r) r = w / 2;
  if (h < 2 * r) r = h / 2;
  this.beginPath();
  this.moveTo(x+r, y);
  this.arcTo(x+w, y,   x+w, y+h, r);
  this.arcTo(x+w, y+h, x,   y+h, r);
  this.arcTo(x,   y+h, x,   y,   r);
  this.arcTo(x,   y,   x+w, y,   r);
  this.closePath();
  return this;
}

Also returning the context so you can chain a little. E.g.:

ctx.roundRect(35, 10, 225, 110, 20).stroke(); //or .fill() for a filled rect

cal_days_in_month() should give you the total number of days in the month, and therefore, the last one.

In jquery you could try this $("#select_id>option:selected").text()

I think the answer is much easier.

To hide the tab you just can use the way you already tried or adressing the TabPage itself.

TabControl1.TabPages.Remove(TabPage1) 'Could be male
TabControl1.TabPages.Remove(TabPage2) 'Could be female

a.s.o.

Removing the TabPage does not destroy it and the controls on it. To show the corresponding tab again just use the following code

TabControl1.TabPages.Insert(0, TabPage1) 'Show male
TabControl1.TabPages.Insert(1, TabPage2) 'Show female

Updated answer

A better way of doing this is:

import subprocess
import sys

reqs = subprocess.check_output([sys.executable, '-m', 'pip', 'freeze'])
installed_packages = [r.decode().split('==')[0] for r in reqs.split()]

The result:

print(installed_packages)

[
    "Django",
    "six",
    "requests",
]

Check if requests is installed:

if 'requests' in installed_packages:
    # Do something

Why this way? Sometimes you have app name collisions. Importing from the app namespace doesn't give you the full picture of what's installed on the system.

Note, that proposed solution works:

• When using pip to install from PyPI or from any other alternative source (like pip install http://some.site/package-name.zip or any other archive type).
• When installing manually using python setup.py install.
• When installing from system repositories, like sudo apt install python-requests.

Cases when it might not work:

• When installing in development mode, like python setup.py develop.
• When installing in development mode, like pip install -e /path/to/package/source/.

Old answer

A better way of doing this is:

import pip
installed_packages = pip.get_installed_distributions()

For pip>=10.x use:

from pip._internal.utils.misc import get_installed_distributions

Why this way? Sometimes you have app name collisions. Importing from the app namespace doesn't give you the full picture of what's installed on the system.

As a result, you get a list of pkg_resources.Distribution objects. See the following as an example:

print installed_packages
[
    "Django 1.6.4 (/path-to-your-env/lib/python2.7/site-packages)",
    "six 1.6.1 (/path-to-your-env/lib/python2.7/site-packages)",
    "requests 2.5.0 (/path-to-your-env/lib/python2.7/site-packages)",
]

Make a list of it:

flat_installed_packages = [package.project_name for package in installed_packages]

[
    "Django",
    "six",
    "requests",
]

Check if requests is installed:

if 'requests' in flat_installed_packages:
    # Do something

Ruby has the tap method (1.8.7, 1.9.3 and 2.1.0) that's very useful for stuff like this.

original_hash = { :a => 'a', :b => 'b' }
original_hash.clone.tap{ |h| h.each{ |k,v| h[k] = v.upcase } }
# => {:a=>"A", :b=>"B"}
original_hash # => {:a=>"a", :b=>"b"}

You should probably consider using css3 for this though it does include the use of vendor prefixes.

I've knocked up a quick fiddle to demo but the crux is this.

<style>
.3col
{
    -webkit-column-count: 3;
    -webkit-column-gap: 10px;
    -moz-column-count: 3;
    -moz-column-gap: 10px;
    column-count:3;
    column-gap:10px;
}
</style>
<div class="3col">
<p>col1</p>
<p>col2</p>
<p>col3</p>
</div>

There is a limit to the total size of all columns inlined into the index definition. That said though, I have never had to create index that wide. To me, the bigger advantage is the fact that you can cover more queries with one index that has included columns as they don't have to be defined in any particular order. Think about is as an index within the index. One example would be the StoreID (where StoreID is low selectivity meaning that each store is associated with a lot of customers) and then customer demographics data (LastName, FirstName, DOB): If you just inline those columns in this order (StoreID, LastName, FirstName, DOB), you can only efficiently search for customers for which you know StoreID and LastName.

On the other hand, defining the index on StoreID and including LastName, FirstName, DOB columns would let you in essence do two seeks- index predicate on StoreID and then seek predicate on any of the included columns. This would let you cover all possible search permutationsas as long as it starts with StoreID.

Synchronize the data/object that you have saved into NSUserDefaults

-(void)saveCustomObject:(Player *)object
{ 
    NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
    NSData *myEncodedObject = [NSKeyedArchiver archivedDataWithRootObject:object];
    [prefs setObject:myEncodedObject forKey:@"testing"];
    [prefs synchronize];
}

Hope this will help you. Thanks

Try looking at Double.TryParse() if you are using .NET 1.1/2.0/3.0/3.5/4.0/4.5

Use gv$session for RAC, if you want get the total number of session across the cluster.

Well, actually I'll have to say David is right with his solution, but there are some topics disturbing me:

1. You should never send your model to the view => This is correct
2. If you create a ViewModel, and include the Model as member in the ViewModel, then you effectively sent your model to the View => this is BAD
3. Using dictionaries to send the options to the view => this not good style

So how can you create a better coupling?

I would use a tool like AutoMapper or ValueInjecter to map between ViewModel and Model. AutoMapper does seem to have the better syntax and feel to it, but the current version lacks a very severe topic: It is not able to perform the mapping from ViewModel to Model (under certain circumstances like flattening, etc., but this is off topic) So at present I prefer to use ValueInjecter.

So you create a ViewModel with the fields you need in the view. You add the SelectList items you need as lookups. And you add them as SelectLists already. So you can query from a LINQ enabled sourc, select the ID and text field and store it as a selectlist: You gain that you do not have to create a new type (dictionary) as lookup and you just move the new SelectList from the view to the controller.

  // StaffTypes is an IEnumerable<StaffType> from dbContext
  // viewModel is the viewModel initialized to copy content of Model Employee  
  // viewModel.StaffTypes is of type SelectList

  viewModel.StaffTypes =
    new SelectList(
        StaffTypes.OrderBy( item => item.Name )
        "StaffTypeID",
        "Type",
        viewModel.StaffTypeID
    );

In the view you just have to call

@Html.DropDownListFor( model => mode.StaffTypeID, model.StaffTypes )

Back in the post element of your method in the controller you have to take a parameter of the type of your ViewModel. You then check for validation. If the validation fails, you have to remember to re-populate the viewModel.StaffTypes SelectList, because this item will be null on entering the post function. So I tend to have those population things separated into a function. You just call back return new View(viewModel) if anything is wrong. Validation errors found by MVC3 will automatically be shown in the view.

If you have your own validation code you can add validation errors by specifying which field they belong to. Check documentation on ModelState to get info on that.

If the viewModel is valid you have to perform the next step:

If it is a create of a new item, you have to populate a model from the viewModel (best suited is ValueInjecter). Then you can add it to the EF collection of that type and commit changes.

If you have an update, you get the current db item first into a model. Then you can copy the values from the viewModel back to the model (again using ValueInjecter gets you do that very quick). After that you can SaveChanges and are done.

Feel free to ask if anything is unclear.

I've just had this happen to me - and (while it was not instantly obvious) it was due to Resharper (R#) being disabled during a licensing issue.

Enabling Resharper fixed this for me!

I'm using MVC 5 but you could try something like this:

public DateTime JobStart { get; set; }

[AssertThat("StartDate >= JobStart", ErrorMessage = "Time Manager may not begin before job start date")]
[DisplayName("Start Date")]
[Required]
public DateTime? StartDate { get; set; }

In your case you would say something like "IsSenior == true". Then you just need to check the validation on your post action.

In my particular case the function was actually missing. The error message is the same. I am using the Postgresql plugin PostGIS and I had to reinstall that for whatever reason.

Yet another solution to get timezone offset:

TimeZone tz = TimeZone.getDefault();
String current_Time_Zone = getGmtOffsetString(tz.getRawOffset());

public static String getGmtOffsetString(int offsetMillis) {
    int offsetMinutes = offsetMillis / 60000;
    char sign = '+';
    if (offsetMinutes < 0) {
        sign = '-';
        offsetMinutes = -offsetMinutes;
    }
    return String.format("GMT%c%02d:%02d", sign, offsetMinutes/60, offsetMinutes % 60);
}

Per Mozilla's Map documentation, you can initialize as follows:

private _gridOptions:Map<string, Array<string>> = 
    new Map([
        ["1", ["test"]],
        ["2", ["test2"]]
    ]);

HttpContext.Current returns an instance of System.Web.HttpContext, which does not extend System.Web.HttpContextBase. HttpContextBase was added later to address HttpContext being difficult to mock. The two classes are basically unrelated (HttpContextWrapper is used as an adapter between them).

Fortunately, HttpContext itself is fakeable just enough for you do replace the IPrincipal (User) and IIdentity.

The following code runs as expected, even in a console application:

HttpContext.Current = new HttpContext(
    new HttpRequest("", "http://tempuri.org", ""),
    new HttpResponse(new StringWriter())
    );

// User is logged in
HttpContext.Current.User = new GenericPrincipal(
    new GenericIdentity("username"),
    new string[0]
    );

// User is logged out
HttpContext.Current.User = new GenericPrincipal(
    new GenericIdentity(String.Empty),
    new string[0]
    );

You can use show innodb status (or show engine innodb status for newer versions of mysql) to get a list of all the actions currently pending inside the InnoDB engine. Buried in the wall of output will be the transactions, and what internal process ID they're running under.

You won't be able to force a commit or rollback of those transactions, but you CAN kill the MySQL process running them, which does essentially boil down to a rollback. It kills the processes' connection and causes MySQL to clean up the mess its left.

Here's what you'd want to look for:

------------
TRANSACTIONS
------------
Trx id counter 0 140151
Purge done for trx's n:o < 0 134992 undo n:o < 0 0
History list length 10
LIST OF TRANSACTIONS FOR EACH SESSION:
---TRANSACTION 0 0, not started, process no 17004, OS thread id 140621902116624
MySQL thread id 10594, query id 10269885 localhost marc
show innodb status

In this case, there's just one connection to the InnoDB engine right now (my login, running the show query). If that line were an actual connection/stuck transaction you'd want to terminate, you'd then do a kill 10594.

@JulienD Best way is to break above process into two steps.

Step 1 : Lets say 'rawList' as your list that you want to add as parameters in prepared statement.

Create another list :

ArrayList<String> listWithQuotes = new ArrayList<String>();

for(String element : rawList){
    listWithQuotes.add("'"+element+"'");
}

Step 2 : Make 'listWithQuotes' comma separated.

String finalString = StringUtils.join(listWithQuotes.iterator(),",");

'finalString' will be string parameters with each element as single quoted and comma separated.

There is 2 way for sort data

1) sorting just data and fill into grid:

DataGridView datagridview1 = new DataGridView(); // for show data
DataTable dt1 = new DataTable(); // have data
DataTable dt2 = new DataTable(); // temp data table
DataRow[] dra = dt1.Select("", "ID DESC");
if (dra.Length > 0)
    dt2 = dra.CopyToDataTable();
datagridview1.DataSource = dt2;

2) sort default view that is like of sort with grid column header:

DataGridView datagridview1 = new DataGridView(); // for show data
DataTable dt1 = new DataTable(); // have data
dt1.DefaultView.Sort = "ID DESC";
datagridview1.DataSource = dt1;

The standard C# convention, which works well enough in Java too, is to prefix all interfaces with an I - so your file handler interface will be IFileHandler and your truck interface will be ITruck. It's consistent, and makes it easy to tell interfaces from classes.

Well this one works...

double roundOff = Math.round(a * 100.0) / 100.0;

Output is

123.14

Or as @Rufein said

 double roundOff = (double) Math.round(a * 100) / 100;

this will do it for you as well.

You can solve this fully in the html:

<div>
  <input ng-model=collapse type=checkbox>Title
  <div ng-show=collapse>
     Only shown when checkbox is clicked
  </div>
</div>

This also works well with ng-repeat since it will create a local scope for each member.

<table>
  <tbody ng-repeat='m in members'>
    <tr>
       <td><input type=checkbox ng-model=collapse></td>
       <td>{{m.title}}</td>
    </tr>
    <tr ng-show=collapse>
      <td> </td>
      <td>{{ m.content }}</td>
    </tr>
  </tbody>
</table>

Be aware that even though a repeat has its own scope, initially it will inherit the value from collapse from super scopes. This allows you to set the initial value in one place but it can be surprising.

You can of course restyle the checkbox. See http://jsfiddle.net/azD5m/5/

Updated fiddle: http://jsfiddle.net/azD5m/374/ Original fiddle used closing </input> tags to add the HTML text label instead of using <label> tags.

npm install jspdf --save

//code on react

import jsPDF from 'jspdf';


var doc = new jsPDF()


 doc.fromHTML("<div>JOmin</div>", 1, 1)


onclick //

 doc.save("name.pdf")

Try this:

yAxis: {min: 0, max: 100}

See this jsfiddle example

In case someone else stumbles upon this question and wants it here is the SASS mixin I use.

@mixin rotate($deg: 90){
    $sDeg: #{$deg}deg;

    -webkit-transform: rotate($sDeg);
    -moz-transform: rotate($sDeg);
    -ms-transform: rotate($sDeg);
    -o-transform: rotate($sDeg);
    transform: rotate($sDeg);
}

I think one way is first to check whether your file exists and if it exists to exclude the folder from copy:

<target name="excludeLocales">

    <property name="de-DE.file" value="${basedir}/locale/de-DE/incompelte.flag"/>
    <available property="de-DE.file.exists" file="${de-DE.file}" />

    <copy todir="C:/temp/">
        <fileset dir="${basedir}/locale">
            <exclude name="de-DE/**" if="${de-DE.file.exists}"/>
            <include name="xy/**"/>
        </fileset>
    </copy>
</target>

This should work also for the other languages.

cv:Mat mat;
int rows = mat.rows;
int cols = mat.cols;

cv::Size s = mat.size();
rows = s.height;
cols = s.width;

Also note that stride >= cols; this means that actual size of the row can be greater than element size x cols. This is different from the issue of continuous Mat and is related to data alignment.

The simplest way is to read a character, and print it right after reading:

int c;
FILE *file;
file = fopen("test.txt", "r");
if (file) {
    while ((c = getc(file)) != EOF)
        putchar(c);
    fclose(file);
}

c is int above, since EOF is a negative number, and a plain char may be unsigned.

If you want to read the file in chunks, but without dynamic memory allocation, you can do:

#define CHUNK 1024 /* read 1024 bytes at a time */
char buf[CHUNK];
FILE *file;
size_t nread;

file = fopen("test.txt", "r");
if (file) {
    while ((nread = fread(buf, 1, sizeof buf, file)) > 0)
        fwrite(buf, 1, nread, stdout);
    if (ferror(file)) {
        /* deal with error */
    }
    fclose(file);
}

The second method above is essentially how you will read a file with a dynamically allocated array:

char *buf = malloc(chunk);

if (buf == NULL) {
    /* deal with malloc() failure */
}

/* otherwise do this.  Note 'chunk' instead of 'sizeof buf' */
while ((nread = fread(buf, 1, chunk, file)) > 0) {
    /* as above */
}

Your method of fscanf() with %s as format loses information about whitespace in the file, so it is not exactly copying a file to stdout.

me.close()

You should try this. I guess it will work.

info is a pointer to a dictionary - you keep adding the same pointer to your list contact.

Insert info = {} into the loop and it should solve the problem:

...
content = []
for iframe in soup.find_all('iframe'):
    info = {}
    info['src'] = iframe.get('src')
    info['height'] = iframe.get('height')
    info['width'] = iframe.get('width')
...

• System properties are set on the Java command line using the -Dpropertyname=value syntax. They can also be added at runtime using System.setProperty(String key, String value) or via the various System.getProperties().load() methods.
  To get a specific system property you can use System.getProperty(String key) or System.getProperty(String key, String def).

• Environment variables are set in the OS, e.g. in Linux export HOME=/Users/myusername or on Windows SET WINDIR=C:\Windows etc, and, unlike properties, may not be set at runtime.
  To get a specific environment variable you can use System.getenv(String name).

Html Code :

    <a id="f">Show First content!</a>
    <br/>
    <a id="s">Show Second content!!</a>
    <div class="a">Default Content</div>
    <div class="ab hideDiv">First content</div>
    <div class="abc hideDiv">Second content</div>

Script code:

$(document).ready(function() {
    $("#f").mouseover(function(){
        $('.a,.abc').addClass('hideDiv');
        $('.ab').removeClass('hideDiv');
    }).mouseout(function() {
        $('.a').removeClass('hideDiv');
        $('.ab,.abc').addClass('hideDiv');
    });

    $("#s").mouseover(function(){
        $('.a,.ab').addClass('hideDiv');
        $('.abc').removeClass('hideDiv');
    }).mouseout(function() {
        $('.a').removeClass('hideDiv');
        $('.ab,.abc').addClass('hideDiv');
    });
});

css code:

.hideDiv
{
    display:none;
}

Simple way to identify the emailid is valid or not.

public static bool EmailIsValid(string email)
{
        return Regex.IsMatch(email, @"^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$");
}

The most efficient way is to take input make the logic and run

so the code is like this to make your own space maker

need = input("Write a string:- ")
result = ''
for character in need:
   result = result + character + ' '
print(result)    # to rid of space after O

but if you want to use what python give then use this code

need2 = input("Write a string:- ")

print(" ".join(need2))

There is another solution, i looked for because a had problems with code like this (it s set the system proxy in firefox):

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("network.proxy.http", "localhost");
profile.setPreference("network.proxy.http_port", "8080");
driver = new FirefoxDriver(profile);

I prefer this solution, it force the proxy manual setting in firefox. To do that, use the org.openqa.selenium.Proxy object to setup Firefox :

FirefoxProfile profile = new FirefoxProfile();
localhostProxy.setProxyType(Proxy.ProxyType.MANUAL);
localhostProxy.setHttpProxy("localhost:8080");
profile.setProxyPreferences(localhostProxy);
driver = new FirefoxDriver(profile);

if it could help...

There is a lot of ways to achieve this. In regards to the way you are asking, with a hidden form element.

create this form element inside your form:

<input type="hidden" name="total" value="">

So your form like this:

<form id="sampleForm" name="sampleForm" method="post" action="phpscript.php">
<input type="hidden" name="total" id="total" value="">
<a href="#" onclick="setValue();">Click to submit</a>
</form>

Then your javascript something like this:

<script>
function setValue(){
    document.sampleForm.total.value = 100;
    document.forms["sampleForm"].submit();
}
</script>

I found the solution to the problem of serializing entities was as follows:

#config/config.yml

services:
    serializer.method:
        class: Symfony\Component\Serializer\Normalizer\GetSetMethodNormalizer
    serializer.encoder.json:
        class: Symfony\Component\Serializer\Encoder\JsonEncoder
    serializer:
        class: Symfony\Component\Serializer\Serializer
        arguments:
            - [@serializer.method]
            - {json: @serializer.encoder.json }

in my controller:

$serializer = $this->get('serializer');

$entity = $this->get('doctrine')
               ->getRepository('myBundle:Entity')
               ->findOneBy($params);


$collection = $this->get('doctrine')
               ->getRepository('myBundle:Entity')
               ->findBy($params);

$toEncode = array(
    'response' => array(
        'entity' => $serializer->normalize($entity),
        'entities' => $serializer->normalize($collection)
    ),
);

return new Response(json_encode($toEncode));

other example:

$serializer = $this->get('serializer');

$collection = $this->get('doctrine')
               ->getRepository('myBundle:Entity')
               ->findBy($params);

$json = $serializer->serialize($collection, 'json');

return new Response($json);

you can even configure it to deserialize arrays in http://api.symfony.com/2.0
