Programs & Examples On #Embedded database

Java DB (Sun's distribution of Apache Derby) now ships in JDK 6!

I've been wanted to do something like Jason Cohen and have been thinking this looks like the easiest way being in the JDK distro (which of last week is now a requirement for my app). Or maybe I am just lazy that way.

If none of the answers helps, you might need to adjust the project properties. Check this other StackOverflow answer on how to do that:

https://stackoverflow.com/a/20857049/56621

In general your .h contains the class defition, which is all your data and all your method declarations. Like this in your case:

A2DD.h:

class A2DD
{
  private:
  int gx;
  int gy;

  public:
  A2DD(int x,int y);    
  int getSum();
};

And then your .cpp contains the implementations of the methods like this:

A2DD.cpp:

A2DD::A2DD(int x,int y)
{
  gx = x;
  gy = y;
}

int A2DD::getSum()
{
  return gx + gy;
}

I dont think python has a catch :)

try:
    connection = manager.connect("I2Cx")
except Exception, e:
    print e

If you want to find the size of all MySQL databases, us this command, it will show their respective sizes in megabytes;

SELECT table_schema "database", sum(data_length + index_length)/1024/1024 "size in MB" FROM information_schema.TABLES GROUP BY table_schema;

If you have large databases, you can use the following command to show the result in gigabytes;

SELECT table_schema "database", sum(data_length + index_length)/1024/1024/1024 "size in GB" FROM information_schema.TABLES GROUP BY table_schema;

If you want to show the size of only a specific database, for example YOUR_DATABASE_NAME, you could use the following query;

SELECT table_schema "database", sum(data_length + index_length)/1024/1024/1024 "size in GB" FROM information_schema.TABLES WHERE table_schema='YOUR_DATABASE_NAME' GROUP BY table_schema;

I don't suggest you just hidding the stricts errors on your project. Intead, you should turn your method to static or try to creat a new instance of the object:

$var = new YourClass();
$var->method();

You can also use the new way to do the same since PHP 5.4:

(new YourClass)->method();

I hope it helps you!

That's not the way to concat in MYSQL. Use the CONCAT function Have a look here: http://dev.mysql.com/doc/refman/4.1/en/string-functions.html#function_concat

ng g component component name

before you type this commend check you will be in your project directive path

Working syntax for multiple optional params:

<Route path="/section/(page)?/:page?/(sort)?/:sort?" component={Section} />

Now, url can be:

1. /section
2. /section/page/1
3. /section/page/1/sort/asc

Use

var arrayNames = (from DataColumn x in dt.Columns
                  select x.ColumnName).ToArray();

    /// <summary>
    /// Print All the Permutations.
    /// </summary>
    /// <param name="inputStr">input string</param>
    /// <param name="strLength">length of the string</param>
    /// <param name="outputStr">output string</param>
    private void PrintAllPermutations(string inputStr, int strLength,string outputStr, int NumberOfChars)
    {
        //Means you have completed a permutation.
        if (outputStr.Length == NumberOfChars)
        {
            Console.WriteLine(outputStr);                
            return;
        }

        //For loop is used to print permutations starting with every character. first print all the permutations starting with a,then b, etc.
        for(int i=0 ; i< strLength; i++)
        {
            // Recursive call : for a string abc = a + perm(bc). b+ perm(ac) etc.
            PrintAllPermutations(inputStr.Remove(i, 1), strLength - 1, outputStr + inputStr.Substring(i, 1), 4);
        }
    }        

You can do this with merge:

df_merged = df1.merge(df2, how='outer', left_index=True, right_index=True)

The keyword argument how='outer' keeps all indices from both frames, filling in missing indices with NaN. The left_index and right_index keyword arguments have the merge be done on the indices. If you get all NaN in a column after doing a merge, another troubleshooting step is to verify that your indices have the same dtypes.

The merge code above produces the following output for me:

                V1    V2
A 2012-01-01  12.0  15.0
  2012-02-01  14.0   NaN
  2012-03-01   NaN  21.0
B 2012-01-01  15.0  24.0
  2012-02-01   8.0   9.0
C 2012-01-01  17.0   NaN
  2012-02-01   9.0   NaN
D 2012-01-01   NaN   7.0
  2012-02-01   NaN  16.0

In windows 7, you may have to edit this file

C:\Users\<UserName>\AppData\Roaming\Subversion\servers

[global]
http-proxy-host = ip.add.re.ss
http-proxy-port = 3128

Or you can use the ItemDataBound event in the code behind.

You're correct, in that example the throws is superfluous. It's possible that it was left there from some previous implementation - perhaps the exception was originally thrown instead of caught in the catch block.

If you want to lookup/associate an object with a unique identifier without modifying the underlying object, you can use a WeakMap:

// Note that object must be an object or array,
// NOT a primitive value like string, number, etc.
var objIdMap=new WeakMap, objectCount = 0;
function objectId(object){
  if (!objIdMap.has(object)) objIdMap.set(object,++objectCount);
  return objIdMap.get(object);
}

var o1={}, o2={}, o3={a:1}, o4={a:1};
console.log( objectId(o1) ) // 1
console.log( objectId(o2) ) // 2
console.log( objectId(o1) ) // 1
console.log( objectId(o3) ) // 3
console.log( objectId(o4) ) // 4
console.log( objectId(o3) ) // 3

Using a WeakMap instead of Map ensures that the objects can still be garbage-collected.

I'm adding another option. The answers above were very useful for me, but I wanted to use jQuery instead of ic-ajax (it seems to have a dependency with Ember when I tried to install through bower). Keep in mind that this solution only works on modern browsers.

In order to implement this on jQuery I used jQuery BinaryTransport. This is a nice plugin to read AJAX responses in binary format.

Then you can do this to download the file and send the headers:

$.ajax({
    url: url,
    type: 'GET',
    dataType: 'binary',
    headers: headers,
    processData: false,
    success: function(blob) {
        var windowUrl = window.URL || window.webkitURL;
        var url = windowUrl.createObjectURL(blob);
        anchor.prop('href', url);
        anchor.prop('download', fileName);
        anchor.get(0).click();
        windowUrl.revokeObjectURL(url);
    }
});

The vars in the above script mean:

• url: the URL of the file
• headers: a Javascript object with the headers to send
• fileName: the filename the user will see when downloading the file
• anchor: it is a DOM element that is needed to simulate the download that must be wrapped with jQuery in this case. For example $('a.download-link').

Session_unset(); only destroys the session variables. To end the session there is another function called session_destroy(); which also destroys the session .

update :

In order to kill the session altogether, like to log the user out, the session id must also be unset. If a cookie is used to propagate the session id (default behavior), then the session cookie must be deleted. setcookie() may be used for that

abs() : Returns the absolute value as per the argument i.e. if argument is int then it returns int, if argument is float it returns float. Also it works on complex variable also i.e. abs(a+bj) also works and returns absolute value i.e.math.sqrt(((a)**2)+((b)**2)

math.fabs() : It only works on the integer or float values. Always returns the absolute float value no matter what is the argument type(except for the complex numbers).

For multiple selection dropdown list,cannot accomplish it directly using dropdown..Can be done in similar ways..

Either you have to use checkbox list or listbox (ajax inclusive)

http://www.codeproject.com/Articles/55184/MultiSelect-Dropdown-in-ASP-NET

http://social.msdn.microsoft.com/Forums/vstudio/en-US/54374df7-5a54-42bc-83b8-ad5994cb634d/multi-select-dropdownlist

http://www.dotnetfunda.com/articles/article1591-multiselect-dropdownlist-in-aspnet-using-csharp-40-.aspx

Assuming you're able to use ECMAScript 2017 you can emulate similar behaviour by using async/await and setTimeout. Here's an example sleep function:

async function sleep(msec) {
    return new Promise(resolve => setTimeout(resolve, msec));
}

You can then use the sleep function in any other async function like this:

async function testSleep() {
    console.log("Waiting for 1 second...");
    await sleep(1000);
    console.log("Waiting done."); // Called 1 second after the first console.log
}

This is nice because it avoids needing a callback. The down side is that it can only be used in async functions. Behind the scenes the testSleep function is paused, and after the sleep completes it is resumed.

From MDN:

The await expression causes async function execution to pause until a Promise is fulfilled or rejected, and to resume execution of the async function after fulfillment.

For a full explanation see:

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function
• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/await

If you wanna have everything into one only piece of code, then you can mix tim's answer with the example's approach found on the API for JTextField, and you'll get something like this:

public class JTextFieldLimit extends JTextField {
    private int limit;

    public JTextFieldLimit(int limit) {
        super();
        this.limit = limit;
    }

    @Override
    protected Document createDefaultModel() {
        return new LimitDocument();
    }

    private class LimitDocument extends PlainDocument {

        @Override
        public void insertString( int offset, String  str, AttributeSet attr ) throws BadLocationException {
            if (str == null) return;

            if ((getLength() + str.length()) <= limit) {
                super.insertString(offset, str, attr);
            }
        }       

    }

}

Then there is no need to add a Document to the JTextFieldLimit due to JTextFieldLimit already have the functionality inside.

As of PowerShell version 7, the ternary operator is built into PowerShell.

1 -gt 2 ? "Yes" : "No"
# Returns "No"

1 -gt 2 ? 'Yes' : $null
# Get a $null response for false-y return value

The closest thing to "for each" is probably MySQL Procedure using Cursor and LOOP.

Hovering over the icon "read only" in mysql workbench shows a tooltip that explains why it cannot be edited. In my case it said, only tables with primary keys or unique non-nullable columns can be edited.

The String class exposes some methods to enable this, such as IndexOf and LastIndexOf, so that you may do this:

Dim myText = "abcde"
Dim dIndex = myText.IndexOf("d")
If (dIndex > -1) Then

End If

This worked for me

var dateToFormat = "2018-05-16 12:57:13"; //TIMESTAMP

moment(dateToFormat).format("DD/MM/YYYY"); // you get "16/05/2018"

See: RFC 3092: Etymology of "Foo", D. Eastlake 3rd et al.

Quoting only the relevant definitions from that RFC for brevity:

2. Used very generally as a sample name for absolutely anything, esp. programs and files (esp. scratch files).

3. First on the standard list of metasyntactic variables used in syntax examples (bar, baz, qux, quux, corge, grault, garply, waldo, fred, plugh, xyzzy, thud). [JARGON]

There are a number of dictionary files available online - if you're on linux, a lot of (all?) distros come with an /etc/dictionaries-common/words file, which you can easily parse (words = open('/etc/dictionaries-common/words').readlines(), eg) for use.

To complete @cpu-100 answer,

in case you don't want to enable/use web interface, you can create a new credentials using command line like below and use it in your code to connect to RabbitMQ.

$ rabbitmqctl add_user YOUR_USERNAME YOUR_PASSWORD
$ rabbitmqctl set_user_tags YOUR_USERNAME administrator
$ rabbitmqctl set_permissions -p / YOUR_USERNAME ".*" ".*" ".*"

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):

letsago = "ID" + str(self.dirDesc.values())

However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:

>>>str({'a':1}.values())
'dict_values([1])'

If you REALLY needed to find the variable this way, you could use the eval function:

>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'

or the globals function:

class Foo(object):
    def __init__(self):
        super(Foo, self).__init__()
    def test(self, name):
        print(globals()[name])

foo = Foo()
bar = 'Hello World!'
foo.text('bar')

However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.

In .NET 3.0 and later you can use the ISOWeek.GetWeekOfDate-Method.

Note that the year in the year + week number format might differ from the year of the DateTime because of weeks that cross the year boundary.

All nice solutions, borrowing and improvising for special case -> If you want to add a label near the arrowhead:

    arr = [2,3]
    txt = “Vector X”
    ax.annotate(txt, arr)
    ax.arrow(0, 0, *arr, head_width=0.05, head_length=0.1)

Necromancing.

I use this to load dependant scripts;
it works with IE8+ without adding any dependency on another library like jQuery !

    function cScriptLoader(files)
    {
        var _this = this;

If it's to load a dynamic list of scripts, write the scripts into an attribute, such as data-main, e.g. <script src="scriptloader.js" data-main="file1.js,file2.js,file3.js,etc." ></script>
and do a element.getAttribute("data-main").split(',')

such as

var target = document.currentScript || (function() {
  var scripts = document.getElementsByTagName('script');
  // Note: this is for IE as IE doesn't support currentScript
  // this does not work if you have deferred loading with async
  // e.g. <script src="..." async="async" ></script>
  // https://web.archive.org/web/20180618155601/https://www.w3schools.com/TAgs/att_script_async.asp
  return scripts[scripts.length - 1];
})();

target.getAttribute("data-main").split(',')

to obtain the list.

Even if fileno(FILE *) may return a file descriptor, be VERY careful not to bypass stdio's buffer. If there is buffer data (either read or unflushed write), reads/writes from the file descriptor might give you unexpected results.

To answer one of the side questions, to convert a file descriptor to a FILE pointer, use fdopen(3)

A practical example when name() and toString() make sense to be different is a pattern where single-valued enum is used to define a singleton. It looks surprisingly at first but makes a lot of sense:

enum SingletonComponent {
    INSTANCE(/*..configuration...*/);

    /* ...behavior... */

    @Override
    String toString() {
      return "SingletonComponent"; // better than default "INSTANCE"
    }
}

In such case:

SingletonComponent myComponent = SingletonComponent.INSTANCE;
assertThat(myComponent.name()).isEqualTo("INSTANCE"); // blah
assertThat(myComponent.toString()).isEqualTo("SingletonComponent"); // better

I was able to solve by simply filling in 127.0.0.1 for the PostgreSQL host address rather than leaving it blank. (Django Example)

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'database_name',
        'USER': 'database_user',
        'PASSWORD': 'pass',
        'HOST': '127.0.0.1',
        'PORT': '',
        }
}

I am not sure about your DBMS. So, I created a temporary table in Redshift and from my experience, I think this query should return what you are looking for:

select min(Id), distinct MailId, EmailAddress, Name
    from yourTableName
    group by MailId, EmailAddress, Name

I see that I am using a GROUP BY clause but you still won't have two rows against any particular MailId.

The error message tells you exactly what's wrong. The Python interpreter needs to know the encoding of the non-ASCII character.

If you want to return U+00A3 then you can say

return u'\u00a3'

which represents this character in pure ASCII by way of a Unicode escape sequence. If you want to return a byte string containing the literal byte 0xA3, that's

return b'\xa3'

(where in Python 2 the b is implicit; but explicit is better than implicit).

The linked PEP in the error message instructs you exactly how to tell Python "this file is not pure ASCII; here's the encoding I'm using". If the encoding is UTF-8, that would be

# coding=utf-8

or the Emacs-compatible

# -*- encoding: utf-8 -*-

If you don't know which encoding your editor uses to save this file, examine it with something like a hex editor and some googling. The Stack Overflow character-encoding tag has a tag info page with more information and some troubleshooting tips.

In so many words, outside of the 7-bit ASCII range (0x00-0x7F), Python can't and mustn't guess what string a sequence of bytes represents. https://tripleee.github.io/8bit#a3 shows 21 possible interpretations for the byte 0xA3 and that's only from the legacy 8-bit encodings; but it could also very well be the first byte of a multi-byte encoding. But in fact, I would guess you are actually using Latin-1, so you should have

# coding: latin-1

as the first or second line of your source file. Anyway, without knowledge of which character the byte is supposed to represent, a human would not be able to guess this, either.

A caveat: coding: latin-1 will definitely remove the error message (because there are no byte sequences which are not technically permitted in this encoding), but might produce completely the wrong result when the code is interpreted if the actual encoding is something else. You really have to know the encoding of the file with complete certainty when you declare the encoding.

when you use the svn:// URI it uses port 3690 and probably won't use http proxy

As pointed in the comments, file is a blob:

file instanceof Blob; // true

And you can get its content with the file reader API https://developer.mozilla.org/en/docs/Web/API/FileReader

Read more: https://developer.mozilla.org/en-US/docs/Using_files_from_web_applications

var input = document.querySelector('input[type=file]');
var textarea = document.querySelector('textarea');

function readFile(event) {
  textarea.textContent = event.target.result;
  console.log(event.target.result);
}

function changeFile() {
  var file = input.files[0];
  var reader = new FileReader();
  reader.addEventListener('load', readFile);
  reader.readAsText(file);
}

input.addEventListener('change', changeFile);

<input type="file">
<textarea rows="10" cols="50"></textarea>

If this is really slow, I suspect you're dealing with a large archive file. It's going to uncompress it once to extract the file list, and then uncompress it N times--where N is the number of files in the archive--for the grep. In addition to all the uncompressing, it's going to have to scan a fair bit into the archive each time to extract each file. One of tar's biggest drawbacks is that there is no table of contents at the beginning. There's no efficient way to get information about all the files in the archive and only read that portion of the file. It essentially has to read all of the file up to the thing you're extracting every time; it can't just jump to a filename's location right away.

The easiest thing you can do to speed this up would be to uncompress the file first (gunzip file.tar.gz) and then work on the .tar file. That might help enough by itself. It's still going to loop through the entire archive N times, though.

If you really want this to be efficient, your only option is to completely extract everything in the archive before processing it. Since your problem is speed, I suspect this is a giant file that you don't want to extract first, but if you can, this will speed things up a lot:

tar zxf file.tar.gz
for f in hopefullySomeSubdir/*; do
  grep -l "string" $f
done

Note that grep -l prints the name of any matching file, quits after the first match, and is silent if there's no match. That alone will speed up the grepping portion of your command, so even if you don't have the space to extract the entire archive, grep -l will help. If the files are huge, it will help a lot.

If you're referring to the concept of accessors, then the simple goal is to hide the underlying storage from arbitrary manipulation. The most extreme mechanism for this is

function Foo(someValue) {
    this.getValue = function() { return someValue; }
    return this;
}

var myFoo = new Foo(5);
/* We can read someValue through getValue(), but there is no mechanism
 * to modify it -- hurrah, we have achieved encapsulation!
 */
myFoo.getValue();

If you're referring to the actual JS getter/setter feature, eg. defineGetter/defineSetter, or { get Foo() { /* code */ } }, then it's worth noting that in most modern engines subsequent usage of those properties will be much much slower than it would otherwise be. eg. compare performance of

var a = { getValue: function(){ return 5; }; }
for (var i = 0; i < 100000; i++)
    a.getValue();

vs.

var a = { get value(){ return 5; }; }
for (var i = 0; i < 100000; i++)
    a.value;

You can find a whole bunch of Linq examples in visual studio. Just select Help -> Samples, and then unzip the Linq samples.

Open the linq samples solution and open the LinqSamples.cs of the SampleQueries project.

The answer you are looking for is in method Linq14:

int[] numbersA = { 0, 2, 4, 5, 6, 8, 9 };
int[] numbersB = { 1, 3, 5, 7, 8 };

var pairs =
   from a in numbersA
   from b in numbersB
   where a < b
   select new {a, b};

$.each(["input[type=text][value=]", "textarea[value=]"], function (index, element) {
              //only empty input and textarea will come here
});

Slightly alternative solution to @jpp's but outputting a YearMonth string:

df['YearMonth'] = pd.to_datetime(df['Date']).apply(lambda x: '{year}-{month}'.format(year=x.year, month=x.month))

res = df.groupby('YearMonth')['Values'].sum()

I believe the best practice is now to use:

$('#object').on('touchend mouseup', function () { });

touchend

The touchend event is fired when a touch point is removed from the touch surface.

The touchend event will not trigger any mouse events.

mouseup

The mouseup event is sent to an element when the mouse pointer is over the element, and the mouse button is released. Any HTML element can receive this event.

The mouseup event will not trigger any touch events.

EXAMPLE

$('#click').on('mouseup', function () { alert('Event detected'); });
$('#touch').on('touchend', function () { alert('Event detected'); });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<h1 id="click">Click me</h1>
<h1 id="touch">Touch me</h1>

EDIT (2017)

As of 2017, browsers starting with Chrome are making steps towards making the click event .on("click") more compatible for both mouse and touch by eliminating the delay generated by tap events on click requests.

This leads to the conclusion that reverting back to using just the click event would be the simplest solution moving forward.

I have not yet done any cross browser testing to see if this is practical.

Try this code:

using System;

namespace Array
{
    class Program
    {
        static void Main()
        {
            int[] number = new int[] {5, 5, 6, 7};

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

The result is:

23

User this function:-

function dateRange($first, $last, $step = '+1 day', $format = 'Y-m-d' ) {
                $dates = array();
                $current = strtotime($first);
                $last = strtotime($last);

                while( $current <= $last ) {    
                    $dates[] = date($format, $current);
                    $current = strtotime($step, $current);
                }
                return $dates;
        }

Usage / function call:-

Increase by one day:-

dateRange($start, $end); //increment is set to 1 day.

Increase by Month:-

dateRange($start, $end, "+1 month");//increase by one month

use third parameter if you like to set date format:-

   dateRange($start, $end, "+1 month", "Y-m-d H:i:s");//increase by one month and format is mysql datetime

var arr = Array.prototype.slice.call( htmlCollection )

will have the same effect using "native" code.

Edit

Since this gets a lot of views, note (per @oriol's comment) that the following more concise expression is effectively equivalent:

var arr = [].slice.call(htmlCollection);

But note per @JussiR's comment, that unlike the "verbose" form, it does create an empty, unused, and indeed unusable array instance in the process. What compilers do about this is outside the programmer's ken.

Edit

Since ECMAScript 2015 (ES 6) there is also Array.from:

var arr = Array.from(htmlCollection);

Edit

ECMAScript 2015 also provides the spread operator, which is functionally equivalent to Array.from (although note that Array.from supports a mapping function as the second argument).

var arr = [...htmlCollection];

I've confirmed that both of the above work on NodeList.

Using top command is the simplest way to check memory usage of the program. RES column shows the real physical memory that is occupied by a process.

For my case, I had a 10g file read in java and each time I got outOfMemory exception. This happened when the value in the RES column reached to the value set in -Xmx option. Then by increasing the memory using -Xmx option everything went fine.

it is better to include it in a <small> tag The HTML <small> tag is used for specifying small print.

Small print (also referred to as "fine print" or "mouseprint") usually refers to the part of a document that contains disclaimers, caveats, or legal restrictions, such as copyrights. And this tag is supported in all major browsers.

<footer>
 <small>&copy; Copyright 2058, Example Corporation</small>
</footer>

        Date userDob = new SimpleDateFormat("yyyy-MM-dd").parse(dob);
        Date today = new Date();
        long diff =  today.getTime() - userDob.getTime();
        int numOfDays = (int) (diff / (1000 * 60 * 60 * 24));
        int hours = (int) (diff / (1000 * 60 * 60));
        int minutes = (int) (diff / (1000 * 60));
        int seconds = (int) (diff / (1000));

There's a super small section in the DOCs that shows how to find/find_all direct children.

https://www.crummy.com/software/BeautifulSoup/bs4/doc/#the-recursive-argument

In your case as you want link1 which is first direct child:

# for only first direct child
soup.find("li", { "class" : "test" }).find("a", recursive=False)

If you want all direct children:

# for all direct children
soup.find("li", { "class" : "test" }).findAll("a", recursive=False)

this solutions is with Kotlin and without using the deprecated function resources.updateConfiguration

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        adjustFontScale(resources.configuration)
    }

    private fun adjustFontScale(configuration: Configuration?) {
        configuration?.let {
            it.fontScale = 1.0F
            val metrics: DisplayMetrics = resources.displayMetrics
            val wm: WindowManager = getSystemService(Context.WINDOW_SERVICE) as WindowManager
            wm.defaultDisplay.getMetrics(metrics)
            metrics.scaledDensity = configuration.fontScale * metrics.density

            baseContext.applicationContext.createConfigurationContext(it)
            baseContext.resources.displayMetrics.setTo(metrics)

        }
    }

Observation: this is the same solution as the above but udpated with Kotlin

You could use the TimeSpan constructor which takes a long for Ticks:

 TimeSpan duration = new TimeSpan(endtime.Ticks - startTime.Ticks);

javac is the Java compiler. java is the JVM and what you use to execute a Java program. You do not execute .java files, they are just source files. Presumably there is .jar somewhere (or a directory containing .class files) that is the product of building it in Eclipse:

java/src/com/mypackage/Main.java
java/classes/com/mypackage/Main.class
java/lib/mypackage.jar

From directory java execute:

java -cp lib/mypackage.jar Main arg1 arg2

do you mean like so:

DateTime datetime = new DateTime();

if (datetime == DateTime.MinValue)
{
    //unassigned
}

or you could use Nullable

DateTime? datetime = null;

 if (!datetime.HasValue)
 {
     //unassigned
 }

select 'DROP TABLE ' + name from sysobjects

To perform Email Validation we have many ways,but simple & easiest way are two methods.

1- Using EditText(....).addTextChangedListener which keeps triggering on every input in an EditText box i.e email_id is invalid or valid

/**
 * Email Validation ex:- [email protected]
*/


final EditText emailValidate = (EditText)findViewById(R.id.textMessage); 

final TextView textView = (TextView)findViewById(R.id.text); 

String email = emailValidate.getText().toString().trim();

String emailPattern = "[a-zA-Z0-9._-]+@[a-z]+\\.+[a-z]+";

emailValidate .addTextChangedListener(new TextWatcher() { 
    public void afterTextChanged(Editable s) { 

    if (email.matches(emailPattern) && s.length() > 0)
        { 
            Toast.makeText(getApplicationContext(),"valid email address",Toast.LENGTH_SHORT).show();
            // or
            textView.setText("valid email");
        }
        else
        {
             Toast.makeText(getApplicationContext(),"Invalid email address",Toast.LENGTH_SHORT).show();
            //or
            textView.setText("invalid email");
        }
    } 
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    // other stuffs 
    } 
    public void onTextChanged(CharSequence s, int start, int before, int count) {
    // other stuffs 
    } 
}); 

2- Simplest method using if-else condition. Take the EditText box string using getText() and compare with pattern provided for email. If pattern doesn't match or macthes, onClick of button toast a message. It ll not trigger on every input of an character in EditText box . simple example shown below.

final EditText emailValidate = (EditText)findViewById(R.id.textMessage); 

final TextView textView = (TextView)findViewById(R.id.text); 

String email = emailValidate.getText().toString().trim();

String emailPattern = "[a-zA-Z0-9._-]+@[a-z]+\\.+[a-z]+";

// onClick of button perform this simplest code.
if (email.matches(emailPattern))
{
Toast.makeText(getApplicationContext(),"valid email address",Toast.LENGTH_SHORT).show();
}
else 
{
Toast.makeText(getApplicationContext(),"Invalid email address", Toast.LENGTH_SHORT).show();
}

set http headers like below in your http request

For Issue C:\PHP\php-cgi.exe - The FastCGI process exited unexpectedly.

The easystream open source library has direct support to convert an OutputStream to an InputStream: http://io-tools.sourceforge.net/easystream/tutorial/tutorial.html

// create conversion
final OutputStreamToInputStream<Void> out = new OutputStreamToInputStream<Void>() {
    @Override
    protected Void doRead(final InputStream in) throws Exception {
           LibraryClass2.processDataFromInputStream(in);
           return null;
        }
    };
try {   
     LibraryClass1.writeDataToTheOutputStream(out);
} finally {
     // don't miss the close (or a thread would not terminate correctly).
     out.close();
}

They also list other options: http://io-tools.sourceforge.net/easystream/outputstream_to_inputstream/implementations.html

• Write the data the data into a memory buffer (ByteArrayOutputStream) get the byteArray and read it again with a ByteArrayInputStream. This is the best approach if you're sure your data fits into memory.
• Copy your data to a temporary file and read it back.
• Use pipes: this is the best approach both for memory usage and speed (you can take full advantage of the multi-core processors) and also the standard solution offered by Sun.
• Use InputStreamFromOutputStream and OutputStreamToInputStream from the easystream library.

<form method="POST" action="chk_kw.php">
    <select name="website_string"> 
        <option selected="selected"></option>
        <option value="abc">abc</option>
        <option value="def">def</option>
        <option value="hij">hij</option>   
    </select>
    <input type="submit">
</form>

• As your form gets more complex, you can a quick check at top of your php script using print_r($_POST);, it'll show what's being submitted an the respective element name.

• To get the submitted value of the element in question do:

  $website_string = $_POST['website_string'];

This worked for me.

sudo apt-get install php-curl

This question was answered well at Can you encode CR/LF in into CSV files?.

Consider also reverse engineering multiple lines in Excel. To embed a newline in an Excel cell, press Alt+Enter. Then save the file as a .csv. You'll see that the double-quotes start on one line and each new line in the file is considered an embedded newline in the cell.

I know this is old, but it's the first example of saving form data to a txt file I found in a quick search. So I've made a couple edits to the above code that makes it work more smoothly. It's now easier to add more fields, including the radio button as @user6573234 requested.

Assuming your categories are in cells A1:A6 and the corresponding values are in B1:B6, you might try typing the formula =MEDIAN(IF($A$1:$A$6="Airline",$B$1:$B$6,"")) in another cell and then pressing CTRL+SHIFT+ENTER.

Using CTRL+SHIFT+ENTER tells Excel to treat the formula as an "array formula". In this example, that means that the IF statement returns an array of 6 values (one of each of the cells in the range $A$1:$A$6) instead of a single value. The MEDIAN function then returns the median of these values. See http://www.cpearson.com/excel/arrayformulas.aspx for a similar example using AVERAGE instead of MEDIAN.

It is recommended to use at least 0.12.2.1.

Starting from wkhtmltopdf >= 0.12.2 it doesn't require X server or emulation anymore. You can download new version from http://wkhtmltopdf.org/downloads.html

The simplest possible solution I found was:

In your markup:

<a [href]="location.path()">Reload</a>

and in your component typescript file:

constructor(
        private location: Location
  ) { }

In case you need the answer to be a member of the input numpy array:

Just to add that the percentile function in numpy by default calculates the output as a linear weighted average of the two neighboring entries in the input vector. In some cases people may want the returned percentile to be an actual element of the vector, in this case, from v1.9.0 onwards you can use the "interpolation" option, with either "lower", "higher" or "nearest".

import numpy as np
x=np.random.uniform(10,size=(1000))-5.0

np.percentile(x,70) # 70th percentile

2.075966046220879

np.percentile(x,70,interpolation="nearest")

The latter is an actual entry in the vector, while the former is a linear interpolation of two vector entries that border the percentile

I was wasting my time on this for hours. Fortunately, I found the solution. If you are using bootstrap admin templates (AdminLTE), this problem may show up. Thing is we have to use adminLTE framework plugins.

example: ifChecked event:

$('input').on('ifChecked', function(event){
   alert(event.type + ' callback');
});

Hope it helps you too.

Since you probably want to keep 2FA enabled for your account, you can set up a ssh key and that way you won't need to type your Github credentials every time you want to push work to Github.

You can find all the ssh setup steps in the documentation. First, make sure you don't currently have any ssh keys (id_rsa.pub, etc.) with $ ls -al ~/.ssh

It's included because your minimum SDK version is set to 10. The ActionBar was introduced in API 11. Eclipse adds it automatically so your app can look more consistent throughout the spectrum of all android versions you are supporting.

No, you can't. JavaScript is executed on the client side (browser), while the session data is stored on the server.

However, you can expose session variables for JavaScript in several ways:

• a hidden input field storing the variable as its value and reading it through the DOM API
• an HTML5 data attribute which you can read through the DOM
• storing it as a cookie and accessing it through JavaScript
• injecting it directly in the JS code, if you have it inline

In JSP you'd have something like:

<input type="hidden" name="pONumb" value="${sessionScope.pONumb} />

or:

<div id="product" data-prodnumber="${sessionScope.pONumb}" />

Then in JS:

// you can find a more efficient way to select the input you want
var inputs = document.getElementsByTagName("input"), len = inputs.length, i, pONumb;
for (i = 0; i < len; i++) {
    if (inputs[i].name == "pONumb") {
        pONumb = inputs[i].value;
        break;
    }
}

or:

var product = document.getElementById("product"), pONumb;
pONumb = product.getAttribute("data-prodnumber");

The inline example is the most straightforward, but if you then want to store your JavaScript code as an external resource (the recommended way) it won't be feasible.

<script>
    var pONumb = ${sessionScope.pONumb};
    [...]
</script>

when you perform a test, you ever have the probabilty to reject the null hypothesis when it is true.

See the nextt R code:

p=function(n){
  x=rnorm(n,0,1)
  s=shapiro.test(x)
  s$p.value
}

rep1=replicate(1000,p(5))
rep2=replicate(1000,p(100))
plot(density(rep1))
lines(density(rep2),col="blue")
abline(v=0.05,lty=3)

The graph shows that whether you have a sample size small or big a 5% of the times you have a chance to reject the null hypothesis when it s true (a Type-I error)

// 1. Random shuffle items
items.sort(function() {return 0.5 - Math.random()})

// 2. Get first item

Shorter:

var item = items.sort(function() {return 0.5 - Math.random()})[0];

To get the current router instance or current location you have to create a Higher order component with withRouter from react-router-dom. otherwise, when you are trying to access this.props.location it will return undefined

Example

import React, { Component } from 'react';
import { withRouter } from 'react-router-dom';

class className extends Component {

      render(){
           return(
                ....
                  )
              }
}

export default withRouter(className)

I just come here to say that, aside from Enumerable.Concat extension method, there seems to be another method named Enumerable.Append in .NET Core 1.1.1. The latter allows you to concatenate a single item to an existing sequence. So Aamol's answer can also be written as

IEnumerable<T> items = new T[]{new T("msg")};
items = items.Append(new T("msg2"));

Still, please note that this function will not change the input sequence, it just return a wrapper that put the given sequence and the appended item together.

Conventions:

• PEP 257 Docstring Conventions
• PEP 287 reStructuredText Docstring Format

Tools:

• Epydoc: Automatic API Documentation Generation for Python
• sphinx.ext.autodoc – Include documentation from docstrings
• PyCharm has some nice support for docstrings

Update: Since Python 3.5 you can use type hints which is a compact, machine-readable syntax:

from typing import Dict, Union

def foo(i: int, d: Dict[str, Union[str, int]]) -> int:
    """
    Explanation: this function takes two arguments: `i` and `d`.
    `i` is annotated simply as `int`. `d` is a dictionary with `str` keys
    and values that can be either `str` or `int`.

    The return type is `int`.

    """

The main advantage of this syntax is that it is defined by the language and that it's unambiguous, so tools like PyCharm can easily take advantage from it.

This code works:

Gson gson = new Gson(); 
String json = "{\"k1\":\"v1\",\"k2\":\"v2\"}";
Map<String,Object> map = new HashMap<String,Object>();
map = (Map<String,Object>) gson.fromJson(json, map.getClass());

It is also very important to distinguish a SENDING multicast socket from a RECEIVING multicast socket.

I agree with all the answers above regarding RECEIVING multicast sockets. The OP noted that binding a RECEIVING socket to an interface did not help. However, it is necessary to bind a multicast SENDING socket to an interface.

For a SENDING multicast socket on a multi-homed server, it is very important to create a separate socket for each interface you want to send to. A bound SENDING socket should be created for each interface.

  // This is a fix for that bug that causes Servers to pop offline/online.
  // Servers will intermittently pop offline/online for 10 seconds or so.
  // The bug only happens if the machine had a DHCP gateway, and the gateway is no longer accessible.
  // After several minutes, the route to the DHCP gateway may timeout, at which
  // point the pingponging stops.
  // You need 3 machines, Client machine, server A, and server B
  // Client has both ethernets connected, and both ethernets receiving CITP pings (machine A pinging to en0, machine B pinging to en1)
  // Now turn off the ping from machine B (en1), but leave the network connected.
  // You will notice that the machine transmitting on the interface with
  // the DHCP gateway will fail sendto() with errno 'No route to host'
  if ( theErr == 0 )
  {
     // inspired by 'ping -b' option in man page:      
     //      -b boundif
     //             Bind the socket to interface boundif for sending.
     struct sockaddr_in bindInterfaceAddr;
     bzero(&bindInterfaceAddr, sizeof(bindInterfaceAddr));
     bindInterfaceAddr.sin_len = sizeof(bindInterfaceAddr);
     bindInterfaceAddr.sin_family = AF_INET;
     bindInterfaceAddr.sin_addr.s_addr = htonl(interfaceipaddr);
     bindInterfaceAddr.sin_port = 0; // Allow the kernel to choose a random port number by passing in 0 for the port.
     theErr = bind(mSendSocketID, (struct sockaddr *)&bindInterfaceAddr, sizeof(bindInterfaceAddr));
     struct sockaddr_in serverAddress;
     int namelen = sizeof(serverAddress);  
     if (getsockname(mSendSocketID, (struct sockaddr *)&serverAddress, (socklen_t *)&namelen) < 0) {
        DLogErr(@"ERROR Publishing service... getsockname err");
     }
     else
     {
        DLog( @"socket %d bind, %@ port %d", mSendSocketID, [NSString stringFromIPAddress:htonl(serverAddress.sin_addr.s_addr)], htons(serverAddress.sin_port) );
     }

Without this fix, multicast sending will intermittently get sendto() errno 'No route to host'. If anyone can shed light on why unplugging a DHCP gateway causes Mac OS X multicast SENDING sockets to get confused, I would love to hear it.

I don't think, You really need to do that just define your TextView in layout file like this

<RelativeLayout
    android:layout_width="width"
    android:layout_height="height">
    <TextView
        android:id="@+id/yourid"
        android:layout_centerInParent="true"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Your text" />
</RelativeLayout>

fwrite() is a smidgen faster and file_put_contents() is just a wrapper around those three methods anyway, so you would lose the overhead. Article

file_put_contents(file,data,mode,context):

The file_put_contents writes a string to a file.

This function follows these rules when accessing a file.If FILE_USE_INCLUDE_PATH is set, check the include path for a copy of filename Create the file if it does not exist then Open the file and Lock the file if LOCK_EX is set and If FILE_APPEND is set, move to the end of the file. Otherwise, clear the file content Write the data into the file and Close the file and release any locks. This function returns the number of the character written into the file on success, or FALSE on failure.

fwrite(file,string,length):

The fwrite writes to an open file.The function will stop at the end of the file or when it reaches the specified length, whichever comes first.This function returns the number of bytes written or FALSE on failure.

The previous answer is pretty good, but I also wanted to mention that there is a fixed layout equivalent for grids, you just need to write minmax(0, 1fr) instead of 1fr as your track size.

None of the solutions worked for me. I upgraded my previous Android Studio to 3.0.1 and received this issue while trying to restart the emulator.

What worked for me was deleting Android Studio from Windows 'Add or Remove Programs'. Then go to C:\Users[User] and delete any android-related folders (.android, .AndroidStudioX.X, Android).

Next go to C:\Users[User]\AppData\Local and delete any Android-related folders there. Restart your system and re-download android studio from their official site (https://developer.android.com/studio/index.html). Install Android Studio from fresh and don't import any old settings.

When Android Studio finishes installing, I launched AVD from 'Tools > Android > AVD Manager', created a pixel 2 device with 4096mb of RAM running Android API P x86. Start it up and it works!

This is an IndexError in python, which means that we're trying to access an index which isn't there in the tensor. Below is a very simple example to understand this error.

# create an empty array of dimension `0`
In [14]: arr = np.array([], dtype=np.int64) 

# check its shape      
In [15]: arr.shape  
Out[15]: (0,)

with this array arr in place, if we now try to assign any value to some index, for example to the index 0 as in the case below

In [16]: arr[0] = 23     

Then, we will get an IndexError, as below:

---

IndexError                                Traceback (most recent call last)
<ipython-input-16-0891244a3c59> in <module>
----> 1 arr[0] = 23

IndexError: index 0 is out of bounds for axis 0 with size 0

The reason is that we are trying to access an index (here at 0^th position), which is not there (i.e. it doesn't exist because we have an array of size 0).

In [19]: arr.size * arr.itemsize  
Out[19]: 0

So, in essence, such an array is useless and cannot be used for storing anything. Thus, in your code, you've to follow the traceback and look for the place where you're creating an array/tensor of size 0 and fix that.

JavaScript is a prototype-oriented language, remember!

Use a for loop instead of .forEach()

var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false

for(var call of myObj) {
    console.log(call)
    
    var a = call['a'], b = call['b']
     
    if(a == null || b == null) {
        result = false
        break
    }
}

<table id="myTable" class="table" cellspacing="0" width="100%">
    <thead>
        <tr>
            <th>Header 1</th>
            <th>Header 2</th>
            <th>Header 3</th>
        </tr>
    </thead>
    <tbody id="tblBody">

    </tbody>
</table>

And Remove:

$("#tblBody").empty();

Add android:textAllCaps="false" in <Button> tag that's it.

The file may be existing but may have a different path. Try writing the absolute path for the file.

Try os.listdir() function to check that atleast python sees the file.

Try it like this:

file1 = open(r'Drive:\Dir\recentlyUpdated.yaml')

As DACW pointed out, there are method-chaining improvements in pandas 0.18.1 that do what you are looking for very nicely.

Rather than using .where, you can pass your function to either the .loc indexer or the Series indexer [] and avoid the call to .dropna:

test = pd.Series({
383:    3.000000,
663:    1.000000,
726:    1.000000,
737:    9.000000,
833:    8.166667
})

test.loc[lambda x : x!=1]

test[lambda x: x!=1]

Similar behavior is supported on the DataFrame and NDFrame classes.

Had the exact same issue. I installed curl 7.19 to /opt/curl/ to make sure that I would not affect current curl on our production servers. Once I linked libcurl.so.4 to /usr/lib:

sudo ln -s /opt/curl/lib/libcurl.so /usr/lib/libcurl.so.4

I still got the same error! Durf.

But running ldconfig make the linkage for me and that worked. No need to set the LD_RUN_PATH or LD_LIBRARY_PATH at all. Just needed to run ldconfig.

I found that an answer to this issue when dealing with math is that the operator on the left hand side must be the variable you are trying to change. The logic cannot come first.

coin1 + coin2 + coin3 = coinTotal; // Wrong

coinTotal = coin1 + coin2 + coin3; // Right

This isn't a direct answer to your question but it might be helpful to future people who google the same thing I googled.

Use the :disabled CSS3 pseudo-selector

Case Insensitive Substring Example

This is an extension of Eugene's answer, which converts the strings to lower case before checking for the substring:

if (index(lc($str), lc($substr)) != -1) {
    print "$str contains $substr\n";
} 

You can use Symbol

var say = Symbol()

function Cat(){
  this[say]() // call private methos
}

Cat.prototype[say] = function(){ alert('im a private') }

P.S. alexpods is not correct. he get protect rather than private, since inheritance is a name conflict

Actually you can use var say = String(Math.random()) instead Symbol

IN ES6:

var say = Symbol()

class Cat {

  constructor(){
    this[say]() // call private
  }

  [say](){
    alert('im private')
  }

}

The ARM architecture was originally designed for Acorn personal computers (See Acorn Archimedes, circa 1987, and RiscPC), which were just as much keyboard-based personal computers as were x86 based IBM PC models. Only later ARM implementations were primarily targeted at the mobile and embedded market segment.

Originally, simple RISC CPUs of roughly equivalent performance could be designed by much smaller engineering teams (see Berkeley RISC) than those working on the x86 development at Intel.

But, nowadays, the fastest ARM chips have very complex multi-issue out-of-order instruction dispatch units designed by large engineering teams, and x86 cores may have something like a RISC core fed by an instruction translation unit.

So, any current differences between the two architectures are more related to the specific market needs of the product niches that the development teams are targeting. (Random opinion: ARM probably makes more in license fees from embedded applications that tend to be far more power and cost constrained. And Intel needs to maintain a performance edge in PCs and servers for their profit margins. Thus you see differing implementation optimizations.)

Memory mapping has a potential for a huge speed advantage compared to traditional IO. It lets the operating system read the data from the source file as the pages in the memory mapped file are touched. This works by creating faulting pages, which the OS detects and then the OS loads the corresponding data from the file automatically.

This works the same way as the paging mechanism and is usually optimized for high speed I/O by reading data on system page boundaries and sizes (usually 4K) - a size for which most file system caches are optimized to.

Okay, so if later on down the line the issue is that you have a query that's greater than the allowable size (which may happen if it keeps growing) you're going to have to break it into chunks and execute the string values. So, let's say you have a stored procedure like the following:

CREATE PROCEDURE ExecuteMyHugeQuery
    @SQL VARCHAR(MAX) -- 2GB size limit as stated by Martin Smith
AS
BEGIN
    -- Now, if the length is greater than some arbitrary value
    -- Let's say 2000 for this example
    -- Let's chunk it
    -- Let's also assume we won't allow anything larger than 8000 total
    DECLARE @len INT
    SELECT @len = LEN(@SQL)

    IF (@len > 8000)
    BEGIN
        RAISERROR ('The query cannot be larger than 8000 characters total.',
                   16,
                   1);
    END

    -- Let's declare our possible chunks
    DECLARE @Chunk1 VARCHAR(2000),
            @Chunk2 VARCHAR(2000),
            @Chunk3 VARCHAR(2000),
            @Chunk4 VARCHAR(2000)

    SELECT @Chunk1 = '',
           @Chunk2 = '',
           @Chunk3 = '',
           @Chunk4 = ''

    IF (@len > 2000)
    BEGIN
        -- Let's set the right chunks
        -- We already know we need two chunks so let's set the first
        SELECT @Chunk1 = SUBSTRING(@SQL, 1, 2000)

        -- Let's see if we need three chunks
        IF (@len > 4000)
        BEGIN
            SELECT @Chunk2 = SUBSTRING(@SQL, 2001, 2000)

            -- Let's see if we need four chunks
            IF (@len > 6000)
            BEGIN
                SELECT @Chunk3 = SUBSTRING(@SQL, 4001, 2000)
                SELECT @Chunk4 = SUBSTRING(@SQL, 6001, (@len - 6001))
            END
              ELSE
            BEGIN
                SELECT @Chunk3 = SUBSTRING(@SQL, 4001, (@len - 4001))
            END
        END
          ELSE
        BEGIN
            SELECT @Chunk2 = SUBSTRING(@SQL, 2001, (@len - 2001))
        END
    END

    -- Alright, now that we've broken it down, let's execute it
    EXEC (@Chunk1 + @Chunk2 + @Chunk3 + @Chunk4)
END

1. Set another project as startup
2. Build the project (the non problematic project will display)
3. Go to the problematic bin\debug folder
4. Rename myservice.vshost.exe to myservice.exe

I believe the problem is that codecs.BOM_UTF8 is a byte string, not a Unicode string. I suspect the file handler is trying to guess what you really mean based on "I'm meant to be writing Unicode as UTF-8-encoded text, but you've given me a byte string!"

Try writing the Unicode string for the byte order mark (i.e. Unicode U+FEFF) directly, so that the file just encodes that as UTF-8:

import codecs

file = codecs.open("lol", "w", "utf-8")
file.write(u'\ufeff')
file.close()

(That seems to give the right answer - a file with bytes EF BB BF.)

EDIT: S. Lott's suggestion of using "utf-8-sig" as the encoding is a better one than explicitly writing the BOM yourself, but I'll leave this answer here as it explains what was going wrong before.

Like Cheeso said:

You don't need the directory on your path. You could put it on your path, but you don't NEED to do that. If you are calling regasm rarely, or calling it from a batch file, you may find it is simpler to just invoke regasm via the fully-qualified pathname on the exe, eg:

%SystemRoot%\Microsoft.NET\Framework\v2.0.50727\regasm.exe MyAssembly.dll

style="border:none; scrolling:no; frameborder:0;  marginheight:0; marginwidth:0; "

Add JSTL library as dependency to your project (javax.servlet.jsp.jstl.core.Config is a part of this package). For example, if you were using Gradle, you could write in a build.gradle:

dependencies {
    compile 'javax.servlet:jstl:1.2'
}

As far as I can see in the manual, it is not possible to call functions inside HEREDOC strings. A cumbersome way would be to prepare the words beforehand:

<?php

    $world = _("World");

    $str = <<<EOF
    <p>Hello</p>
    <p>$world</p>
EOF;
    echo $str;
?>

a workaround idea that comes to mind is building a class with a magic getter method.

You would declare a class like this:

class Translator
{
 public function __get($name) {
  return _($name); // Does the gettext lookup
  }
 }

Initialize an object of the class at some point:

  $translate = new Translator();

You can then use the following syntax to do a gettext lookup inside a HEREDOC block:

    $str = <<<EOF
    <p>Hello</p>
    <p>{$translate->World}</p>
EOF;
    echo $str;
?>

$translate->World will automatically be translated to the gettext lookup thanks to the magic getter method.

To use this method for words with spaces or special characters (e.g. a gettext entry named Hello World!!!!!!, you will have to use the following notation:

 $translate->{"Hello World!!!!!!"}

This is all untested but should work.

Update: As @mario found out, it is possible to call functions from HEREDOC strings after all. I think using getters like this is a sleek solution, but using a direct function call may be easier. See the comments on how to do this.

They are project files, that hold the module information and meta data.

Just add *.iml to .gitignore.

This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....

To cover the identities listed:

IIS_IUSRS:

This is analogous to the old IIS6 IIS_WPG group. It's a built-in group with it's security configured such that any member of this group can act as an application pool identity.

IUSR:

This account is analogous to the old IUSR_<MACHINE_NAME> local account that was the default anonymous user for IIS5 and IIS6 websites (i.e. the one configured via the Directory Security tab of a site's properties).

For more information about IIS_IUSRS and IUSR see:

Understanding Built-In User and Group Accounts in IIS 7

DefaultAppPool:

If an application pool is configured to run using the Application Pool Identity feature then a "synthesised" account called IIS AppPool\<pool name> will be created on the fly to used as the pool identity. In this case there will be a synthesised account called IIS AppPool\DefaultAppPool created for the life time of the pool. If you delete the pool then this account will no longer exist. When applying permissions to files and folders these must be added using IIS AppPool\<pool name>. You also won't see these pool accounts in your computers User Manager. See the following for more information:

Application Pool Identities

ASP.NET v4.0: -

This will be the Application Pool Identity for the ASP.NET v4.0 Application Pool. See DefaultAppPool above.

NETWORK SERVICE: -

The NETWORK SERVICE account is a built-in identity introduced on Windows 2003. NETWORK SERVICE is a low privileged account under which you can run your application pools and websites. A website running in a Windows 2003 pool can still impersonate the site's anonymous account (IUSR_ or whatever you configured as the anonymous identity).

In ASP.NET prior to Windows 2008 you could have ASP.NET execute requests under the Application Pool account (usually NETWORK SERVICE). Alternatively you could configure ASP.NET to impersonate the site's anonymous account via the <identity impersonate="true" /> setting in web.config file locally (if that setting is locked then it would need to be done by an admin in the machine.config file).

Setting <identity impersonate="true"> is common in shared hosting environments where shared application pools are used (in conjunction with partial trust settings to prevent unwinding of the impersonated account).

In IIS7.x/ASP.NET impersonation control is now configured via the Authentication configuration feature of a site. So you can configure to run as the pool identity, IUSR or a specific custom anonymous account.

LOCAL SERVICE:

The LOCAL SERVICE account is a built-in account used by the service control manager. It has a minimum set of privileges on the local computer. It has a fairly limited scope of use:

LocalService Account

LOCAL SYSTEM:

You didn't ask about this one but I'm adding for completeness. This is a local built-in account. It has fairly extensive privileges and trust. You should never configure a website or application pool to run under this identity.

LocalSystem Account

In Practice:

In practice the preferred approach to securing a website (if the site gets its own application pool - which is the default for a new site in IIS7's MMC) is to run under Application Pool Identity. This means setting the site's Identity in its Application Pool's Advanced Settings to Application Pool Identity:

In the website you should then configure the Authentication feature:

Right click and edit the Anonymous Authentication entry:

Ensure that "Application pool identity" is selected:

When you come to apply file and folder permissions you grant the Application Pool identity whatever rights are required. For example if you are granting the application pool identity for the ASP.NET v4.0 pool permissions then you can either do this via Explorer:

Click the "Check Names" button:

Or you can do this using the ICACLS.EXE utility:

icacls c:\wwwroot\mysite /grant "IIS AppPool\ASP.NET v4.0":(CI)(OI)(M)

...or...if you site's application pool is called BobsCatPicBlogthen:

icacls c:\wwwroot\mysite /grant "IIS AppPool\BobsCatPicBlog":(CI)(OI)(M)

I hope this helps clear things up.

Update:

I just bumped into this excellent answer from 2009 which contains a bunch of useful information, well worth a read:

The difference between the 'Local System' account and the 'Network Service' account?

publish data where stoloc = 'AB143' 
|
[select prtnum where stoloc = @stoloc]

This is how the @ works.

In WPF, you can easily do it in this way:

this.button.RaiseEvent(new RoutedEventArgs(Button.ClickEvent));

vector<vector<int>> board;
for(int i=0;i<m;i++) {
    board.push_back({});
    for(int j=0;j<n;j++) {
        board[i].push_back(0);
    }
}

This code snippet first inserts an empty vector at each turn, in the other nested loop it pushes the elements inside the vector created by the outer loop. Hope this solves the problem.

To avoid potentially unexpected results when using GROUP BY without an aggregate function, as is used in the accepted answer, because MySQL is free to retrieve ANY value within the data set being grouped when not using an aggregate function [sic] and issues with ONLY_FULL_GROUP_BY. Please consider using an exclusion join.

Exclusion Join - Unambiguous Entities

Assuming the firstname and lastname are uniquely indexed (unambiguous), an alternative to GROUP BY is to sort using a LEFT JOIN to filter the result set, otherwise known as an exclusion JOIN.

See Demonstration

Ascending order (A-Z)

To retrieve the distinct firstname ordered by lastname from A-Z

Query

SELECT t1.*
FROM table_name AS t1
LEFT JOIN table_name AS t2
ON t1.firstname = t2.firstname
AND t1.lastname > t2.lastname
WHERE t2.id IS NULL;

Result

| id | firstname | lastname |
|----|-----------|----------|
|  2 |      Bugs |    Bunny |
|  1 |      John |      Doe |

Descending order (Z-A)

To retrieve the distinct firstname ordered by lastname from Z-A

Query

SELECT t1.*
FROM table_name AS t1
LEFT JOIN table_name AS t2
ON t1.firstname = t2.firstname
AND t1.lastname < t2.lastname
WHERE t2.id IS NULL;

Result

| id | firstname | lastname |
|----|-----------|----------|
|  2 |      Bugs |    Bunny |
|  3 |      John |  Johnson |

You can then order the resulting data as desired.

Exclusion Join - Ambiguous Entities

If the first and last name combination are not unique (ambiguous) and you have multiple rows of the same values, you can filter the result set by including an OR condition on the JOIN criteria to also filter by id.

See Demonstration

table_name data

(1, 'John', 'Doe'),
(2, 'Bugs', 'Bunny'),
(3, 'John', 'Johnson'),
(4, 'John', 'Doe'),
(5, 'John', 'Johnson')

Query

SELECT t1.*
FROM table_name AS t1
LEFT JOIN table_name AS t2
ON t1.firstname = t2.firstname
AND (t1.lastname > t2.lastname
OR (t1.firstname = t1.firstname AND t1.lastname = t2.lastname AND t1.id > t2.id))
WHERE t2.id IS NULL;

Result

| id | firstname | lastname |
|----|-----------|----------|
|  1 |      John |      Doe |
|  2 |      Bugs |    Bunny |

Ordered Subquery

EDIT

My original answer using an ordered subquery, was written prior to MySQL 5.7.5, which is no longer applicable, due to the changes with ONLY_FULL_GROUP_BY. Please use the exclusion join examples above instead.

It is also important to note; when ONLY_FULL_GROUP_BY is disabled (original behavior prior to MySQL 5.7.5), the use of GROUP BY without an aggregate function may yield unexpected results, because MySQL is free to choose ANY value within the data set being grouped [sic].

Meaning an ID or lastname value may be retrieved that is not associated with the retrieved firstname row.

WARNING

With MySQL GROUP BY may not yield the expected results when used with ORDER BY

See Test Case Example

The best method of implementation, to ensure expected results, is to filter the result set scope using an ordered subquery.

table_name data

(1, 'John', 'Doe'),
(2, 'Bugs', 'Bunny'),
(3, 'John', 'Johnson')

Query

SELECT * FROM (
    SELECT * FROM table_name ORDER BY ID DESC
) AS t1
GROUP BY FirstName

Result

| ID | first |    last |
|----|-------|---------|
|  2 |  Bugs |   Bunny |
|  3 |  John | Johnson |

Comparison

To demonstrate the unexpected results when using GROUP BY in combination with ORDER BY

Query

SELECT * FROM table_name GROUP BY FirstName ORDER BY ID DESC

Result

| ID | first |  last |
|----|-------|-------|
|  2 |  Bugs | Bunny |
|  1 |  John |   Doe |

make sure ,use this 404 route wrote on the bottom of the code.

syntax will be like

{
    path: 'page-not-found', 
    component: PagenotfoundComponent
},
{
    path: '**', 
    redirectTo: '/page-not-found'
},

Thank you

Use String.Substring() (details here) to cut left part, then your replacement, then right part. Play with indexes until you get it right :)

Something like:

string replacement=original.Substring(0,start)+
    rep+original.Substring(start+rep.Length);

an easiest way which i used and worked well

date('Y-m-d', strtotime('-1 year'));

this worked perfect.. hope this will help someone else too.. :)

Here's the simplest, most robust, and scalable solution to get tabs on the bottom of the screen.

1. In your vertical LinearLayout, put the FrameLayout above the TabWidget
2. Set layout_height to wrap_content on both FrameLayout and TabWidget
3. Set FrameLayout's android:layout_weight="1"
4. Set TabWidget's android:layout_weight="0" (0 is default, but for emphasis, readability, etc)
5. Set TabWidget's android:layout_marginBottom="-4dp" (to remove the bottom divider)

Full code:

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp">

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:padding="5dp"
            android:layout_weight="1"/>

        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="0"
            android:layout_marginBottom="-4dp"/>

    </LinearLayout>

</TabHost>

Here's an answer regarding the XML configuration, note that if you don't give the file appender a ConversionPattern it will create 0 byte file and not write anything:

I would suggest starting with the most straightforward solutions first - maybe simple HTTP Basic Authentication + HTTPS is enough in your scenario.

If not (for example you cannot use https, or need more complex key management), you may have a look at HMAC-based solutions as suggested by others. A good example of such API would be Amazon S3 (http://s3.amazonaws.com/doc/s3-developer-guide/RESTAuthentication.html)

I wrote a blog post about HMAC based authentication in ASP.NET Web API. It discusses both Web API service and Web API client and the code is available on bitbucket. http://www.piotrwalat.net/hmac-authentication-in-asp-net-web-api/

Here is a post about Basic Authentication in Web API: http://www.piotrwalat.net/basic-http-authentication-in-asp-net-web-api-using-message-handlers/

Remember that if you are going to provide an API to 3rd parties, you will also most likely be responsible for delivering client libraries. Basic authentication has a significant advantage here as it is supported on most programming platforms out of the box. HMAC, on the other hand, is not that standardized and will require custom implementation. These should be relatively straightforward but still require work.

PS. There is also an option to use HTTPS + certificates. http://www.piotrwalat.net/client-certificate-authentication-in-asp-net-web-api-and-windows-store-apps/

Section 6.5.8.6 of the C standard says:

Each of the operators < (less than), > (greater than), <= (less than or equal to), and >= (greater than or equal to) shall yield 1 if the specified relation is true and 0 if it is false.) The result has type int.

Its should work for all version of eclipse even in Spring tool suit(STS). Here is the steps

Go to the URl Follow The link to download or click the bellow link to direct download Click Here to download

Download JD-Eclipse. Download and unzip the JD-Eclipse Update Site,

Launch Eclipse,

Click on "Help > Install New Software...",

Click on button "Add..." to add an new repository,

Enter "JD-Eclipse Update Site" and select the local site directory,

Select extracted folder and give any name. I have given JDA. and click ok.

Check "Java Decompiler Eclipse Plug-in",

Next, next, next... and restart Eclipse.

MyList.OrderBy(x => x.StartDate).ThenByDescending(x => x.EndDate);

Note that you can use as well the Descending keyword in the OrderBy (in case you need). So another possible answer is:

MyList.OrderByDescending(x => x.StartDate).ThenByDescending(x => x.EndDate);

I know the thread is too old to post an answer. But still i think it is worth it.

Though you can't have an explicit constructor, if your intention is to call the constructor of the super class, then the following is all you have to do.

StoredProcedure sp = new StoredProcedure(datasource, spName) {
    {// init code if there are any}
};

This is an example of creating a StoredProcedure object in Spring by passing a DataSource and a String object.

So the Bottom line is, if you want to create an anonymous class and want to call the super class constructor then create the anonymous class with a signature matching the super class constructor.

How about something like this?

val newDF = df.filter($"B" === "").take(1) match {
  case Array() => df
  case _ => df.withColumn("D", $"B" === "")
}

Using take(1) should have a minimal hit

This acronym might help you to remember the ASP.NET life cycle stages which I wrote about in the below blog post.

From my blog: Understand ASP.NET Page life cycle and remember stages in easy way
18 May 2014

This is a clarification because I have seen things done in code which are honestly confusing - I think the following example might assist others.

As others have said before - Bitmap inherits from the Abstract Image class

Abstract effectively means you cannot create a New() instance of it.

    Image imgBad1 = new Image();        // Bad - won't compile
    Image imgBad2 = new Image(200,200); // Bad - won't compile

But you can do the following:

    Image imgGood;  // Not instantiated object!
    // Now you can do this
    imgGood = new Bitmap(200, 200);

You can now use imgGood as you would the same bitmap object if you had done the following:

    Bitmap bmpGood = new Bitmap(200,200);

The nice thing here is you can draw the imgGood object using a Graphics object

    Graphics gr = default(Graphics);
    gr = Graphics.FromImage(new Bitmap(1000, 1000));
    Rectangle rect = new Rectangle(50, 50, imgGood.Width, imgGood.Height); // where to draw
    gr.DrawImage(imgGood, rect);

Here imgGood can be any Image object - Bitmap, Metafile, or anything else that inherits from Image!

Now that the ::marker element is available in evergreen browsers, this is how you could use it, including using :hover to change the marker. As you can see, now you can use any Unicode character you want as a list item marker and even use custom counters.

@charset "UTF-8";
@counter-style fancy {
  system: fixed;
  symbols:   ;
  suffix: " ";
}

p {
  margin-left: 8em;
}

p.note {
  display: list-item;
  counter-increment: note-counter;
}

p.note::marker {
  content: "Note " counter(note-counter) ":";
}

ol {
  margin-left: 8em;
  padding-left: 0;
}

ol li {
  list-style-type: lower-roman;
}

ol li::marker {
  color: blue;
  font-weight: bold;
}

ul {
  margin-left: 8em;
  padding-left: 0;
}

ul.happy li::marker {
  content: "";
}

ul.happy li:hover {
  color: blue;
}

ul.happy li:hover::marker {
  content: "";
}

ul.fancy {
  list-style: fancy;
}

<p>This is the first paragraph in this document.</p>
<p class="note">This is a very short document.</p>
<ol>
  <li>This is the first item.
    <li>This is the second item.
      <li>This is the third item.
</ol>
<p>This is the end.</p>

<ul class="happy">
  <li>Item 1</li>
  <li>Item 2</li>
  <li>Item 3</li>
</ul>

<ul class="fancy">
  <li>Item 1</li>
  <li>Item 2</li>
  <li>Item 3</li>
</ul>

From about section of Reverse IP Domain Check tool on yougetsignal:

A reverse IP domain check takes a domain name or IP address pointing to a web server and searches for other sites known to be hosted on that same web server. Data is gathered from search engine results, which are not guaranteed to be complete.

Simple answer .

(1) Put input element type="file" anywhere on page and set attribute type="hidden" or style="display:none". Give an id to input element. e.g. id="myid"

(2) Chose any div, image, button or any element which you want to use to open file dialog box, set an onclick attribute to it, like this- onclick="document.getElementById('myid').click()"

That is all.

For this you can simply use the redirect function that is included in flask

from flask import Flask, redirect

app = Flask(__name__)

@app.route('/')
def hello():
    return redirect("https://www.exampleURL.com", code = 302)

if __name__ == "__main__":
    app.run()

Another useful tip(as you're new to flask), is to add app.debug = True after initializing the flask object as the debugger output helps a lot while figuring out what's wrong.

grep -R "somestring" | cut -d ":" -f 1

They use a combination of IP geolocation, as well as comparing the results of a scan for nearby wireless networks with a database on their side (which is built by collecting GPS coordinates alongside wifi scan data when Android phone users use their GPS)

I was facing this issue when I added Nuget package Newtonsoft.Json 12.0.0.2 into my two .netstandard library projects and it grabbed almost my full day to solve this issue.

Exception -: Could not load file or assembly 'Newtonsoft.Json, Version=12.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed'. The system cannot find the file specified.

Solution -: I had to remove package from Nuget and went to the following location and followed the next steps -

Step 1. Go to location "C:\Users[UserName].nuget\packages\newtonsoft.json\12.0.2\lib" and here you will get all Nuget versions you installed previously.

Step 2. Since i wanted to use it in my .netstandard 2.0 library project, so i copied "netstandard2.0" folder from this location and paste somewhere my preferred location (**where i generally keep 3rd party dlls).

Step 3. Now i added DLL reference from here to my both project and this way problem solved.

Thanks

First creates the function

$.UrlExists = function(url) {_x000D_
 var http = new XMLHttpRequest();_x000D_
    http.open('HEAD', url, false);_x000D_
    http.send();_x000D_
    return http.status!=404;_x000D_
}

After using the function as follows

if($.UrlExists("urlimg")){_x000D_
 foto = "img1.jpg";_x000D_
}else{_x000D_
 foto = "img2.jpg";_x000D_
}_x000D_
_x000D_
$('<img>').attr('src',foto);

console.log(OBJECT|ARRAY|STRING|...);
console.info(OBJECT|ARRAY|STRING|...);
console.debug(OBJECT|ARRAY|STRING|...);
console.warn(OBJECT|ARRAY|STRING|...);
console.assert(Condition, 'Message if false');

These Should work correctly On Google Chrome and Mozilla Firefox (if you are running with old version of firefox, so you have to install Firebug plugin)
On Internet Explorer 8 or higher you must do as follow:

• Launch "Developer Tools, by clicking on F12 Button
• On the Tab List, click on "Script" Tab"
• Click on "Console" Button in the right side

Quick alternative

import timeit

start = timeit.default_timer()

#Your statements here

stop = timeit.default_timer()

print('Time: ', stop - start)  

How about this? Assuming SQL Server 2008:

SELECT CAST(StartDate as date) AS ForDate,
       DATEPART(hour,StartDate) AS OnHour,
       COUNT(*) AS Totals
FROM #Events
GROUP BY CAST(StartDate as date),
       DATEPART(hour,StartDate)

For pre-2008:

SELECT DATEADD(day,datediff(day,0,StartDate),0)   AS ForDate,
       DATEPART(hour,StartDate) AS OnHour,
       COUNT(*) AS Totals
FROM #Events
GROUP BY CAST(StartDate as date),
       DATEPART(hour,StartDate)

This results in :

ForDate                 | OnHour | Totals
-----------------------------------------
2011-08-09 00:00:00.000     12       3

came across this post.

let str = 'As sly as a fox, as strong as an ox';

let target = 'as'; // let's look for it

let pos = 0;
while (true) {
  let foundPos = str.indexOf(target, pos);
  if (foundPos == -1) break;

  alert( `Found at ${foundPos}` );
  pos = foundPos + 1; // continue the search from the next position
}

The same algorithm can be layed out shorter:

let str = "As sly as a fox, as strong as an ox";
let target = "as";

let pos = -1;
while ((pos = str.indexOf(target, pos + 1)) != -1) {
  alert( pos );
}

As mentioned, the .data() method won't actually set the value of the data- attribute, nor will it read updated values if the data- attribute changes.

My solution was to extend jQuery with a .realData() method that actually corresponds to the current value of the attribute:

// Alternative to .data() that updates data- attributes, and reads their current value.
(function($){
  $.fn.realData = function(name,value) {
      if (value === undefined) {
        return $(this).attr('data-'+name);
      } else {
        $(this).attr('data-'+name,value);
      }
  };
})(jQuery);

NOTE: Sure you could just use .attr(), but from my experience, most developers (aka me) make the mistake of viewing .attr() and .data() as interchangeable, and often substitute one for the other without thinking. It might work most of the time, but it's a great way to introduce bugs, especially when dealing with any sort of dynamic data binding. So by using .realData(), I can be more explicit about the intended behavior.

I think this could work:

select * from tbl where statusid = isnull(@statusid,statusid)

Range("A10") = WorksheetFunction.Sum(Worksheets("Sheet1").Range("A1", "A9"))

Where

Range("A10") is the answer cell

Range("A1", "A9") is the range to calculate

Use: ALTER TABLE mytable MODIFY mycolumn VARCHAR(255);

You can view the error-output of your test runner by opening the Output panel (view-->output) and choosing "tests" from the "Show output from" dropdown

Additionally, if you have Resharper installed you can open a test file and hover over the test-circle next to a test to get additional error info

Clicking that will bring you to a window with more detailed information. Alternatively, you can open that window by going to Extensions --> Reshaper --> Windows --> Unit Test Exploration Results

Fortunately a solution exists. You must add a wrapper for parent and change z-index of this wrapper for example 10, and set z-index for child to -1:

.parent {_x000D_
    position: relative;_x000D_
    width: 750px;_x000D_
    height: 7150px;_x000D_
    background: red;_x000D_
    border: solid 1px #000;_x000D_
    z-index: initial;_x000D_
}_x000D_
_x000D_
.child {_x000D_
    position: relative;_x000D_
    background-color: blue;_x000D_
    z-index: -1;_x000D_
    color: white;_x000D_
}_x000D_
_x000D_
.wrapper {_x000D_
    position: relative;_x000D_
    background: green;_x000D_
    z-index: 10;_x000D_
}

<div class="wrapper">_x000D_
    <div class="parent">parent parent_x000D_
        <div class="child">child child child</div>_x000D_
    </div>_x000D_
</div>

If you're using jQuery, this is a kinda cool way to manipulate elements in javascript without adding them to the DOM:

var myAnchor = $("<a />");

//set href    
myAnchor.attr('href', 'http://example.com/path/to/myfile')

//your link's features
var hostname = myAnchor.attr('hostname'); // http://example.com
var pathname = myAnchor.attr('pathname'); // /path/to/my/file
//...etc

The quickest method is:

df.sort_index(axis=1)

Be aware that this creates a new instance. Therefore you need to store the result in a new variable:

sortedDf=df.sort_index(axis=1)

I like the Gnome xml parser. It's open source (MIT License, so you can use it in commercial products), fast and has DOM and SAX based interfaces.

http://xmlsoft.org/

It seems that Accessibility controls in the iOS Settings override pretty much everything you try to do color-wise to the navigation bar buttons. Make sure you have all the settings to the default positions (set increase contrast, bold text, button shapes, etc to off) otherwise you won't see anything change. Once I did it, all the color change code started working as expected. You might not need to turn them all off, but I didn't pursue it further.

Since you need to handle the date string before it is converted to a date in your model, I'd override the accessor for that field

Let's say your date field is published_date. Add this to your model object:

def published_date=(value)
    # do sanity checking here
    # then hand it back to rails to convert and store
    self.write_attribute(:published_date, value) 
end

In C# (since you tagged it as such) you could use a LINQ expression like this:

List<Control> c = Controls.OfType<TextBox>().Cast<Control>().ToList();

Edit for recursion:

In this example, you first create the list of controls and then call a method to populate it. Since the method is recursive, it doesn't return the list, it just updates it.

List<Control> ControlList = new List<Control>();
private void GetAllControls(Control container)
{
    foreach (Control c in container.Controls)
    {
        GetAllControls(c);
        if (c is TextBox) ControlList.Add(c);
    }
}

It may be possible to do this in one LINQ statement using the Descendants function, though I am not as familiar with it. See this page for more information on that.

Edit 2 to return a collection:

As @ProfK suggested, a method that simply returns the desired controls is probably better practice. To illustrate this I have modified the code as follows:

private IEnumerable<Control> GetAllTextBoxControls(Control container)
{
    List<Control> controlList = new List<Control>();
    foreach (Control c in container.Controls)
    {
        controlList.AddRange(GetAllTextBoxControls(c));
        if (c is TextBox)
            controlList.Add(c);
    }
    return controlList;
}

Received the same error , the problem was difference in the version of Android SDK which AVD was using and the version in AndroidManifest file. I could solve it by correcting the

android:minSdkVersion="16"

to match with AVD.

Programs that prompt for passwords usually set the tty into "raw" mode, and read input directly from the tty. If you spawn the subprocess in a pty you can make that work. That is what Expect does...

Copy-paste the following into your current terminal:

gsettings set org.gnome.desktop.default-applications.terminal exec /usr/bin/terminator
gsettings set org.gnome.desktop.default-applications.terminal exec-arg "-x"

This modifies the dconf to make terminator the default program. You could also use dconf-editor (a GUI-based tool) to make changes to the dconf, as another answer has suggested. If you would like to learn and understand more about this topic, this may help you.

kubectl create can work with one object configuration file at a time. This is also known as imperative management

kubectl create -f filename|url

kubectl apply works with directories and its sub directories containing object configuration yaml files. This is also known as declarative management. Multiple object configuration files from directories can be picked up. kubectl apply -f directory/

document.location.href="/";

or

 window.location.href = "/";

According to the W3C, they are the same. In reality, for cross browser safety, you should use window.location rather than document.location.

See: http://www.w3.org/TR/Window/#window-location

(Note: I copied the difference explanation above, from this question.)

On the DataGridView, set the DataPropertyName of the columns to your column names of your DataTable.

Instead of setting the ng-model to item.size.code, how about setting it to size:

<select ng-options="size as size.name for size in sizes" 
   ng-model="item" ng-change="update()"></select>

Then in your update() method, $scope.item will be set to the currently selected item.

And whatever code needed item.size.code, can get that property via $scope.item.code.

Fiddle.

Update based on more info in comments:

Use some other $scope property for your select ng-model then:

<select ng-options="size as size.name for size in sizes" 
   ng-model="selectedItem" ng-change="update()"></select>

Controller:

$scope.update = function() {
   $scope.item.size.code = $scope.selectedItem.code
   // use $scope.selectedItem.code and $scope.selectedItem.name here
   // for other stuff ...
}

This is helpfull, its work for me..

$('.bd-example-modal-sm').on('hidden.bs.modal', function () { 
      $(this).find("select").val('').end(); // Clear dropdown content
      $("ul").empty();   // Clear li content 
});

package-lock.json is written to when a numerical value in a property such as the "version" property, or a dependency property is changed in package.json.

If these numerical values in package.json and package-lock.json match, package-lock.json is read from.

If these numerical values in package.json and package-lock.json do not match, package-lock.json is written to with those new values, and new modifiers such as the caret and tilde if they are present. But it is the numeral that is triggering the change to package-lock.json.

To see what I mean, do the following. Using package.json without package-lock.json, run npm install with:

{
  "name": "test",
  "version": "1.0.0",
  ...
  "devDependencies": {
    "sinon": "7.2.2"
  }
}

package-lock.json will now have:

"sinon": {
  "version": "7.2.2",

Now copy/paste both files to a new directory. Change package.json to (only adding caret):

{
  "name": "test",
  "version": "1.0.0",
  ...
  "devDependencies": {
    "sinon": "^7.2.2"
  }
}

run npm install. If there were no package-lock.json file, [email protected] would be installed. npm install is reading from package-lock.json and installing 7.2.2.

Now change package.json to:

{
  "name": "test",
  "version": "1.0.0",
  ...
  "devDependencies": {
    "sinon": "^7.3.0"
  }
}

run npm install. package-lock.json has been written to, and will now show:

"sinon": {
  "version": "^7.3.0",

Make sure that you have valid cacerts in the JRE/security, otherwise you will not bypass the invalid empty trustAnchors error.

In my Amazon EC2 Opensuse12 installation, the problem was that the file pointed by the cacerts in the JRE security directory was invalid:

I understood that you could use the keytool to generate a new one (http://mail.openjdk.java.net/pipermail/distro-pkg-dev/2010-April/008961.html). I'll probably have to that soon.

var str ="hello";
str.Where(c => c == 'l').Count()  // 2

The "import" keyword is for attaching python definitions that are created external to the current python program. So in your case, where you just want to read a file with some text in it, use:

text = open("words.txt", "rb").read()

This functions should help you...

bool isThereSpace(String s){
    return s.Contains(" ");
}

Took me a while to find this out but if you a number stored in a variable, say x and you want to select it, use

document.querySelector('a[data-a= + CSS.escape(x) + ']'). 

This is due to some attribute naming specifications that I'm not yet very familiar with. Hope this will help someone.

You could only convert a JSON array into a CSV file.

Lets say, you have a JSON like the following :

{"infile": [{"field1": 11,"field2": 12,"field3": 13},
            {"field1": 21,"field2": 22,"field3": 23},
            {"field1": 31,"field2": 32,"field3": 33}]}

Lets see the code for converting it to csv :

import java.io.File;
import java.io.IOException;

import org.apache.commons.io.FileUtils;
import org.json.CDL;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

public class JSON2CSV {
    public static void main(String myHelpers[]){
        String jsonString = "{\"infile\": [{\"field1\": 11,\"field2\": 12,\"field3\": 13},{\"field1\": 21,\"field2\": 22,\"field3\": 23},{\"field1\": 31,\"field2\": 32,\"field3\": 33}]}";

        JSONObject output;
        try {
            output = new JSONObject(jsonString);


            JSONArray docs = output.getJSONArray("infile");

            File file=new File("/tmp2/fromJSON.csv");
            String csv = CDL.toString(docs);
            FileUtils.writeStringToFile(file, csv);
        } catch (JSONException e) {
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }        
    }

}

Now you got the CSV generated from JSON.

It should look like this:

field1,field2,field3
11,22,33
21,22,23
31,32,33

The maven dependency was like,

<dependency>
    <groupId>org.json</groupId>
    <artifactId>json</artifactId>
    <version>20090211</version>
</dependency>

Update Dec 13, 2019:

Updating the answer, since now we can support complex JSON Arrays as well.

import java.nio.file.Files;
import java.nio.file.Paths;

import com.github.opendevl.JFlat;

public class FlattenJson {

    public static void main(String[] args) throws Exception {
        String str = new String(Files.readAllBytes(Paths.get("path_to_imput.json")));

        JFlat flatMe = new JFlat(str);

        //get the 2D representation of JSON document
        flatMe.json2Sheet().headerSeparator("_").getJsonAsSheet();

        //write the 2D representation in csv format
        flatMe.write2csv("path_to_output.csv");
    }

}

dependency and docs details are in link

The command is date

To customise the output there are a myriad of options available, see date --help for a list.

For example, date '+%A %W %Y %X' gives Tuesday 34 2013 08:04:22 which is the name of the day of the week, the week number, the year and the time.

I had a similar problem with dynamically adding datepicker classes. The solution I found was to comment out line 46 of datepicker.js

// this.element.on('click', $.proxy(this.show, this));

It might be useful to assign a null in a string rather than explicitly making some index the null char '\0'. I've used this for testing functions that handle strings ensuring they stay within their appropriate bounds.

With:

char test_src[] = "fuu\0foo";

This creates an array of size 8 with values:

{'f', 'u', 'u', '\0', 'f', 'o', 'o', '\0'}

Similar to the answer posted by @suganya this doesn't directly answer the question but is a quicker alternative for a single table:

DESCRIBE column_name;

I had the same issue today using primefaces (primeng) and angular 7. Add the following to your style.css

p-button {
   -webkit-appearance: none !important;
}

i am also using a bit of bootstrap which has a reboot.css, that overrides it with (thats why i had to add !important)

button {
  -webkit-appearance: button;

}

This is the updated version for Swift 2.0 - 2.2

 var isEmail: Bool {
    do {
        let regex = try NSRegularExpression(pattern: "^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$", options: .CaseInsensitive)
        return regex.firstMatchInString(self, options: NSMatchingOptions(rawValue: 0), range: NSMakeRange(0, self.characters.count)) != nil
    } catch {
        return false
    }
}

Isn't something like this really easier:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

char str[10];

I know this post is old but here is what I found. It doesn't work when I link it this way(with / before css/style.csson the href attribute.

<link rel="stylesheet" media="all" href="/CSS/Style.css" type="text/css" />

However, when I removed / I'm able to link properly with the css file It should be like this(without /).

<link rel="stylesheet" media="all" href="CSS/Style.css" type="text/css" />

This was giving me trouble on my project. Hope it will help somebody else.

Even when they say that all services and factories are singleton, I don't agree 100 percent with that. I would say that factories are not singletons and this is the point of my answer. I would really think about the name that defines every component(Service/Factory), I mean:

A factory because is not a singleton, you can create as many as you want when you inject, so it works like a factory of objects. You can create a factory of an entity of your domain and work more comfortably with this objects which could be like an object of your model. When you retrieve several objects you can map them in this objects and it can act kind of another layer between the DDBB and the AngularJs model.You can add methods to the objects so you oriented to objects a little bit more your AngularJs App.

Meanwhile a service is a singleton, so we can only create 1 of a kind, maybe not create but we have only 1 instance when we inject in a controller, so a service provides more like a common service(rest calls,functionality.. ) to the controllers.

Conceptually you can think like services provide a service, factories can create multiple instances(objects) of a class

I solved this by:

1. Shutting down my MySQL server: mysql.server stop
2. Running MySQL in safe mode: mysqld_safe --skip-grant-tables
3. In another terminal, login with mysql -u root
4. In the same terminal, run UPDATE mysql.user SET authentication_string=null WHERE User='root';, then FLUSH PRIVILEGES; and then exit with exit;
5. Stop the safe mode server with mysql.server stop and then start the normal one; mysql.server start

Now you can set your new password with

ALTER USER 'root'@'localhost' IDENTIFIED WITH caching_sha2_password BY 'yourpasswd';

The windows handle limit for your application is 10,000 handles. You're getting the error because your program is creating too many handles. You'll need to find the memory leak. As other users have suggested, use a Memory Profiler. I use the .Net Memory Profiler as well. Also, make sure you're calling the dispose method on controls if you're removing them from a form before the form closes (otherwise the controls won't dispose). You'll also have to make sure that there are no events registered with the control. I myself have the same issue, and despite what I already know, I still have some memory leaks that continue to elude me..

if

event.currentTarget.performance.navigation.type

returns

0 => user just typed in an Url
1 => page reloaded
2 => back button clicked.

You must create your template files in the correct location; in the templates subdirectory next to the python module (== the module where you create your Flask app).

The error indicates that there is no home.html file in the templates/ directory. Make sure you created that directory in the same directory as your python module, and that you did in fact put a home.html file in that subdirectory. If your app is a package, the templates folder should be created inside the package.

myproject/
    app.py
    templates/
        home.html

myproject/
    mypackage/
        __init__.py
        templates/
            home.html

Alternatively, if you named your templates folder something other than templates and don't want to rename it to the default, you can tell Flask to use that other directory.

app = Flask(__name__, template_folder='template')  # still relative to module

You can ask Flask to explain how it tried to find a given template, by setting the EXPLAIN_TEMPLATE_LOADING option to True. For every template loaded, you'll get a report logged to the Flask app.logger, at level INFO.

This is what it looks like when a search is successful; in this example the foo/bar.html template extends the base.html template, so there are two searches:

[2019-06-15 16:03:39,197] INFO in debughelpers: Locating template "foo/bar.html":
    1: trying loader of application "flaskpackagename"
       class: jinja2.loaders.FileSystemLoader
       encoding: 'utf-8'
       followlinks: False
       searchpath:
         - /.../project/flaskpackagename/templates
       -> found ('/.../project/flaskpackagename/templates/foo/bar.html')
[2019-06-15 16:03:39,203] INFO in debughelpers: Locating template "base.html":

       followlinks: False
       searchpath:
         - /.../project/flaskpackagename/templates
       -> found ('/.../project/flaskpackagename/templates/base.html')

Blueprints can register their own template directories too, but this is not a requirement if you are using blueprints to make it easier to split a larger project across logical units. The main Flask app template directory is always searched first even when using additional paths per blueprint.

This seems to be premature microoptimization. The compiler is free to produce the same code for both cases or at least for these two

if len(s) != 0 { ... }

and

if s != "" { ... }

because the semantics is clearly equal.

RIGHT(CONVERT(VARCHAR(10), reg_dte, 105), 7) 

I have something different stuff for you which is easy and effective.

    <style> 
    .case-after:after { // set your properties here like eg: 
        color:#3fd309 !important; 
     } 
     .case-before:before { // set your properties here like eg: 
        color:#151715 !important; 
     }
 </style>
  // case for after
    $('#button-id').on('click', function() {
        $(".target-div").toggleClass('case-after');
    });

     // case for before
    $('#button-id').on('click', function() {
        $(".target-div").toggleClass('case-before');
    });

I have used Gnostice in the past and found them to be very good.

If you want to set 4 sides separately use:

border-width: 1px 2em 5px 0; /* top right bottom left */
border-style: solid dotted inset double;
border-color: #f00 #0f0 #00f #ff0;

You can use the LocalCommand command-line option if the PermitLocalCommand option is enabled:

ssh username@hostname -o LocalCommand="tmux list-sessions"

For more details about the available options, see the ssh_config man page.

Now we have to use android.hardware.camera2 as android.hardware.Camera is deprecated which will only work on API >23 FlashLight

   public class MainActivity extends AppCompatActivity {

     Button button;

     Boolean light=true;

     CameraDevice cameraDevice;

     private CameraManager cameraManager;

     private CameraCharacteristics cameraCharacteristics;

     String cameraId;

     @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button=(Button)findViewById(R.id.button);
        cameraManager = (CameraManager) 
        getSystemService(Context.CAMERA_SERVICE);
        try {
          cameraId = cameraManager.getCameraIdList()[0];
        } catch (CameraAccessException e) {
            e.printStackTrace();
        }
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(light){
                    try {

                        cameraManager.setTorchMode(cameraId,true);
                    } catch (CameraAccessException e) {
                        e.printStackTrace();
                    }

                    light=false;}
                    else {

                    try {

                      cameraManager.setTorchMode(cameraId,false);
                    } catch (CameraAccessException e) {
                        e.printStackTrace();
                    }


                    light=true;
                    }


            }
        });
    }
}

It looks like what you really want a ListView with a custom adapter to inflate the specified layout. Using an ArrayAdapter and the method notifyDataSetChanged() you have full control of the Views generation and rendering.

Take a look at these tutorials

Assuming you do as David Zaslavsky suggests, so that the first argument simply is the program to run (no option-parsing required), you're dealing with the question of how to pass arguments 2 and on to your external program. Here's a convenient way:

#!/bin/bash
ext_program="$1"
shift
"$ext_program" "$@"

The shift will remove the first argument, renaming the rest ($2 becomes $1, and so on).$@` refers to the arguments, as an array of words (it must be quoted!).

If you must have your --file syntax (for example, if there's a default program to run, so the user doesn't necessarily have to supply one), just replace ext_program="$1" with whatever parsing of $1 you need to do, perhaps using getopt or getopts.

If you want to roll your own, for just the one specific case, you could do something like this:

if [ "$#" -gt 0 -a "${1:0:6}" == "--file" ]; then
    ext_program="${1:7}"
else
    ext_program="default program"
fi

If you see there is a method _numpy(), e.g for an EagerTensor simply call the above method and you will get an ndarray.

I think the ISO version is smaller than the Layout method because the ISO version is just in English or whatever language it is that you choose, however the "Layout" version is ALL of the languages available, So for example if the "Layout" version downloads a 3gb file(English Version) it will download the same 3gb file in another language that you will not ever use wasting your downloads, time and all that other good stuff.
