You could use a dictionary. The definition is the same. But to save you time, Overhead is work required to do the productive work. For instance, an algorithm runs and does useful work, but requires memory to do its work. This memory allocation takes time, and is not directly related to the work being done, therefore is overhead.

Combining what Dick Lucas says and adding a reset autoincremental from other StackOverFlow posts, i think this can work:

fun clearAndResetAllTables(): Boolean {
    val db = db ?: return false

    // reset all auto-incrementalValues
    val query = SimpleSQLiteQuery("DELETE FROM sqlite_sequence")

    db.beginTransaction()
    return try {
        db.clearAllTables()
        db.query(query)
        db.setTransactionSuccessful()
        true
    } catch (e: Exception){
        false
    } finally {
        db.endTransaction()
    }
}

For those coming across this question more recently, .values is deprecated as of Sequelize 3.0.0. Use .get() instead to get the plain javascript object. So the above code would change to:

var nodedata = node.get({ plain: true });

Sequelize docs here

Calling window.setTimeout(function, delay) will allow you to accomplish this. Here's an example that will automatically close the alert 2 seconds (or 2000 milliseconds) after it is displayed.

$(".alert-message").alert();
window.setTimeout(function() { $(".alert-message").alert('close'); }, 2000);

If you want to wrap it in a nifty function you could do this.

function createAutoClosingAlert(selector, delay) {
   var alert = $(selector).alert();
   window.setTimeout(function() { alert.alert('close') }, delay);
}

Then you could use it like so...

createAutoClosingAlert(".alert-message", 2000);

I am certain there are more elegant ways to accomplish this.

to clear all scribbles in the map use

map.clear()

Here are the common characters which need to be escaped in XML, starting with double quotes:

1. double quotes (") are escaped to "
2. ampersand (&) is escaped to &
3. single quotes (') are escaped to '
4. less than (<) is escaped to <
5. greater than (>) is escaped to >

Don't depends on builder or notification. Use custom code for vibrate.

public static void vibrate(Context context, int millis){
    try {
        Vibrator v = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            v.vibrate(VibrationEffect.createOneShot(millis, VibrationEffect.DEFAULT_AMPLITUDE));
        } else {
            v.vibrate(millis);
        }
    }catch(Exception ex){
    }
}

I doubt anything is killing the process just because it takes a long time. Killed generically means something from the outside terminated the process, but probably not in this case hitting Ctrl-C since that would cause Python to exit on a KeyboardInterrupt exception. Also, in Python you would get MemoryError exception if that was the problem. What might be happening is you're hitting a bug in Python or standard library code that causes a crash of the process.

It's running every minute of the hour 22 I guess. Try the following to run it every first minute of the hour 22:

Using Java 8

With Java 8 you can simply convert your list to a stream allowing you to write:

import java.util.List;
import java.util.stream.Collectors;

List<Sample> list = new ArrayList<Sample>();
List<Sample> result = list.stream()
    .filter(a -> Objects.equals(a.value3, "three"))
    .collect(Collectors.toList());

Note that

• a -> Objects.equals(a.value3, "three") is a lambda expression
• result is a List with a Sample type
• It's very fast, no cast at every iteration
• If your filter logic gets heavier, you can do list.parallelStream() instead of list.stream() (read this)

Apache Commons

If you can't use Java 8, you can use Apache Commons library and write:

import org.apache.commons.collections.CollectionUtils;
import org.apache.commons.collections.Predicate;

Collection result = CollectionUtils.select(list, new Predicate() {
     public boolean evaluate(Object a) {
         return Objects.equals(((Sample) a).value3, "three");
     }
 });

// If you need the results as a typed array:
Sample[] resultTyped = (Sample[]) result.toArray(new Sample[result.size()]);

Note that:

• There is a cast from Object to Sample at each iteration
• If you need your results to be typed as Sample[], you need extra code (as shown in my sample)

Bonus: A nice blog article talking about how to find element in list.

Use getElementById() if it's available.

Also, here's an easy way to do it with jQuery:

if ($('#elementId').length > 0) {
  // Exists.
}

And if you can't use third-party libraries, just stick to base JavaScript:

var element =  document.getElementById('elementId');
if (typeof(element) != 'undefined' && element != null)
{
  // Exists.
}

1--> {Simple Insertion when table column sequence is known}
    Insert into Table1
    values(1,2,...)

2--> {Simple insertion mention column}  
    Insert into Table1(col2,col4)
    values(1,2)

3--> {bulk insertion when num of selected collumns of a table(#table2) are equal to Insertion table(Table1) }   
    Insert into Table1 {Column sequence}
    Select * -- column sequence should be same.
       from #table2

4--> {bulk insertion when you want to insert only into desired column of a table(table1)}
    Insert into Table1 (Column1,Column2 ....Desired Column from Table1)  
    Select Column1,Column2..desired column from #table2

The method I use is one of these or Hmisc::cut2(value, g=4):

temp$quartile <- with(temp, cut(value, 
                                breaks=quantile(value, probs=seq(0,1, by=0.25), na.rm=TRUE), 
                                include.lowest=TRUE))

An alternate might be:

temp$quartile <- with(temp, factor(
                            findInterval( val, c(-Inf,
                               quantile(val, probs=c(0.25, .5, .75)), Inf) , na.rm=TRUE), 
                            labels=c("Q1","Q2","Q3","Q4")
      ))

The first one has the side-effect of labeling the quartiles with the values, which I consider a "good thing", but if it were not "good for you", or the valid problems raised in the comments were a concern you could go with version 2. You can use labels= in cut, or you could add this line to your code:

temp$quartile <- factor(temp$quartile, levels=c("1","2","3","4") )

Or even quicker but slightly more obscure in how it works, although it is no longer a factor, but rather a numeric vector:

temp$quartile <- as.numeric(temp$quartile)

I've had success without the full package, do you know where the call chain is getting interrupted? If you debug with Log()'s, at what point does it no longer work?

I think it may be in your IntentService, this all looks fine.

When Python parses a function, it notes when a variable assignment is made. When there is an assignment, it assumes by default that that variable is a local variable. To declare that the assignment refers to a global variable, you must use the global declaration.

When you access a variable in a function, its value is looked up using the LEGB scoping rules.

So, the first example

  x = 1
  def inc():
      x += 5
  inc()

produces an UnboundLocalError because Python determined x inside inc to be a local variable,

while accessing x works in your second example

 def inc():
    print x

because here, in accordance with the LEGB rule, Python looks for x in the local scope, does not find it, then looks for it in the extended scope, still does not find it, and finally looks for it in the global scope successfully.

You can use exec command to redirect all stdout/stderr output of any commands later.

sample script:

exec 2> your_file2 > your_file1

Python documentation for sys.exit([arg])says:

The optional argument arg can be an integer giving the exit status (defaulting to zero), or another type of object. If it is an integer, zero is considered “successful termination” and any nonzero value is considered “abnormal termination” by shells and the like. Most systems require it to be in the range 0-127, and produce undefined results otherwise.

Moreover to retrieve the return value of the last executed program you could use the $? bash predefined variable.

Anyway if you put a string as arg in sys.exit() it should be printed at the end of your program output in a separate line, so that you can retrieve it just with a little bit of parsing. As an example consider this:

outputString=`python myPythonScript arg1 arg2 arg3 | tail -0`

Although this is a pretty old thread, I just found something out. I created a new database, then added a user, and finally went to use phpMyAdmin to upload the .sql file. total failure. The system doesn't recognize which DB I'm aiming at...

When I start fresh WITHOUT first attaching a new user, and then perform the same phpMyAdmin import, it works fine.

you can try writing the command using 'sudo':

sudo mkdir DirName

Try :

Configure in web config file

<system.web> <globalization culture="ja-JP" uiCulture="zh-HK" /> </system.web>

eg: DateTime dt = DateTime.ParseExact("08/21/2013", "MM/dd/yyyy", null);

ref url : http://support.microsoft.com/kb/306162/

Please use parenthesis () to access the list elements list_name(index)

\n is a line break. /n is not.

use of \n with

1. echo directly to page

Now if you are trying to echo string to the page:

echo  "kings \n garden";

output will be:

kings garden

you won't get garden in new line because PHP is a server-side language, and you are sending output as HTML, you need to create line breaks in HTML. HTML doesn't understand \n. You need to use the nl2br() function for that.

What it does is:

Returns string with <br /> or <br> inserted before all newlines (\r\n, \n\r, \n and \r).

echo  nl2br ("kings \n garden");

Output

kings
garden

Note Make sure you're echoing/printing \n in double quotes, else it will be rendered literally as \n. because php interpreter parse string in single quote with concept of as is

so "\n" not '\n'

2. write to text file

Now if you echo to text file you can use just \n and it will echo to a new line, like:

$myfile = fopen("test.txt", "w+")  ;

$txt = "kings \n garden";
fwrite($myfile, $txt);
fclose($myfile);
 

output will be:

kings
 garden

show all directry and sub directories

def dir():

from glob import glob

dir = []

dir = glob("path")

def all_sub_dir(dir):
{

     for item in dir:

            {
                b = "{}\*".format(item)
                dir += glob(b)
            }
         print(dir)
}

This should work for all PHP versions. It determines the PHP version, then checks to see if the session is started based on the PHP version. Then if the session is not started it starts it.

function start_session() {
  if(version_compare(phpversion(), "5.4.0") != -1){
    if (session_status() == PHP_SESSION_NONE) {
      session_start();
    }
  } else {
    if(session_id() == '') {
      session_start();
    }
  }
}

Instead of RenderViewToString I prefer a approach like

return Json(new { Url = Url.Action("Evil", model) });

then you can catch the result in your javascript and do something like

success: function(data) {
    $.post(data.Url, function(partial) { 
        $('#IdOfDivToUpdate').html(partial);
    });
}

Double quotes should work too... it should create a string, then it should APPEND/INSERT the casted STRING value of $myVar in between 2 empty strings.

Use .*, and make sure you are using your implementations' equivalent of single-line so you will match on line endings.

There is a great explanation here -> http://www.regular-expressions.info/dot.html

I got a easy solution which will select from database table and let you do easily.

SELECT b.FirstName + b.LastName FROM tbl_Users b WHERE b.Id='11'

You can easily add a space there if you try

SELECT b.FirstName +' '+ b.LastName FROM Users b WHERE b.Id='23'

Here you can combine as much as your table have.

You can use run-as shell command to access private application data.

If you only want to copy database you can use this snippet, provided in https://stackoverflow.com/a/31504263/998157

adb -d shell "run-as com.example.test cat /data/data/com.example.test/databases/data.db" > data.db

Vanilla JS

ES2016:

const found = arr1.some(r=> arr2.includes(r))

ES6:

const found = arr1.some(r=> arr2.indexOf(r) >= 0)

How it works

some(..) checks each element of the array against a test function and returns true if any element of the array passes the test function, otherwise, it returns false. indexOf(..) >= 0 and includes(..) both return true if the given argument is present in the array.

are you picky with using Unicode because with java its more simple if you write your program to use "dec" value or (HTML-Code) then you can simply cast data types between char and int

char a = 98;
char b = 'b';
char c = (char) (b+0002);

System.out.println(a);
System.out.println((int)b);
System.out.println((int)c);
System.out.println(c);

Gives this output

b
98
100
d

My goal was to pass a query string similar to:

 protodb?sql=select * from protodb.prototab

to a Node.js 12 Lambda function via a URL from the API gateway. I tried a number of the ideas from the other answers but really wanted to do something in the most API gateway UI native way possible, so I came up with this that worked for me (as of the UI for API Gateway as of December 2020):

On the API Gateway console for a given API, under resources, select the get method. Then select its Integration Request and fill out the data for the lambda function at the top of the page.

Scroll to the bottom and open up the mapping templates section. Choose Request Body Passthrough when there are no templates defined (recommended).

Click on Add mapping templates and create one with the content-type of application/json and hit the check mark button.

For that mapping template, choose the Method Request passthrough on the drop down list for generate template which will fill the textbox under it with AWS' general way to pass everything.

Hit the save button.

Now when I tested it, I could not get the parameter to come through as event.sql under node JS in the Lambda function. It turns out that when the API gateway sends the URL sql query parameter to the Lambda function, it comes through for Node.js as:

 var insql = event.params.querystring.sql;

So the trick that took some time for me was to use JSON.stringify to show the full event stack and then work my way down through the sections to be able to pull out the sql parameter from the query string.

So basically you can use the default passthrough functionality in the API gateway with the trick being how the parameters are passed when you are in the Lambda function.

Using ASP.NET's visible="false" property will set the visibility attribute where as I think when you call show() in jQuery it modifies the display attribute of the CSS style.

So doing the latter won't rectify the former.

You need to do this:

$("#test1").attr("visibility", "visible");

As mentioned by Jon F Hancock, this is how a fragment can 'close' the activity by suggesting the activity to close. This makes the fragment portable as is the reason for them. If you use it in a different activity, you might not want to close the activity.

Code below is a snippet from an activity and fragment which has a save and cancel button.

PlayerActivity

public class PlayerActivity extends Activity 
    implements PlayerInfo.PlayerAddListener {

    public void onPlayerCancel() {
       // Decide if its suitable to close the activity, 
       //e.g. is an edit being done in one of the other fragments?
       finish();
    }
}

PlayerInfoFragment, which contains an interface which the calling activity needs to implement.

public class PlayerInfoFragment extends Fragment {
   private PlayerAddListener callback; // implemented in the Activity

   @Override
   public void onAttach(Activity activity) {
     super.onAttach(activity);
     callback= (PlayerAddListener) activity;
   }

   public interface PlayerAddListener {
       public void onPlayerSave(Player p); // not shown in impl above
       public void onPlayerCancel();
   }

   public void btnCancel(View v) {
      callback.onPlayerCancel(); // the activity's implementation
   }
}

If using @worldofjr answer in jQuery you are getting error:

e.relatedTarget.data is not a function

you should use:

$('#myModal').on('show.bs.modal', function (e) {
    var loadurl = $(e.relatedTarget).data('load-url');
    $(this).find('.modal-body').load(loadurl);
});

Not that e.relatedTarget if wrapped by $(..)

I was getting the error in latest Bootstrap 3 and after using this method it's working without any problem.

Tomalak already gave you a correct answer, but I would like to add that most of the times when you would like to know the VBA code needed to do a certain action in the user interface it is a good idea to record a macro.

In this case click Record Macro on the developer tab of the Ribbon, freeze the top row and then stop recording. Excel will have the following macro recorded for you which also does the job:

With ActiveWindow
    .SplitColumn = 0
    .SplitRow = 1
End With
ActiveWindow.FreezePanes = True

You need to uncomment max_input_vars value in php.ini file and increase it (exp. 2000), also dont forget to restart your server this will help for 99,99%.

Two ways come to mind:

• Using a command-line tool like the popular ffmpeg, however you will almost always need an own server (or a very nice server administrator / hosting company) to get that

• Using the "screenshoot" plugin for the LongTail Video player that allows the creation of manual screenshots that are then sent to a server-side script.

You need to ensure that any code that modifies the HTTP headers is executed before the headers are sent. This includes statements like session_start(). The headers will be sent automatically when any HTML is output.

Your problem here is that you're sending the HTML ouput at the top of your page before you've executed any PHP at all.

Move the session_start() to the top of your document :

<?php    session_start(); ?> <html> <head> <title>PHP SDK</title> </head> <body> <?php require_once 'src/facebook.php';    // more PHP code here. 

Self-Signed Certificate Authorities pip / conda

After extensively documenting a similar problem with Git (How can I make git accept a self signed certificate?), here we are again behind a corporate firewall with a proxy giving us a MitM "attack" that we should trust and:

NEVER disable all SSL verification!

This creates a bad security culture. Don't be that person.

tl;dr

pip config set global.cert path/to/ca-bundle.crt
pip config list
conda config --set ssl_verify path/to/ca-bundle.crt
conda config --show ssl_verify

# Bonus while we are here...
git config --global http.sslVerify true
git config --global http.sslCAInfo path/to/ca-bundle.crt

But where do we get ca-bundle.crt?

I recommend you open up this cacert.pem file in a text editor as we will need to add our self-signed CA to this file.

Certificates are a document complying with X.509 but they can be encoded to disk a few ways. The below article is a good read but the short version is that we are dealing with the base64 encoding which is often called PEM in the file extensions. You will see it has the format:

----BEGIN CERTIFICATE----
....
base64 encoded binary data
....
----END CERTIFICATE----

Getting our Self Signed Certificate

Below are a few options on how to get our self signed certificate:

• Via OpenSSL CLI
• Via Browser
• Via Python Scripting

Thanks to this answer and the linked blog, it shows steps (on Windows) how to view the certificate and then copy to file using the base64 PEM encoding option.

Copy the contents of this exported file and paste it at the end of your cacerts.pem file.

For consistency rename this file cacerts.pem --> ca-bundle.crt and place it somewhere easy like:

# Windows
%USERPROFILE%\certs\ca-bundle.crt

# or *nix
$HOME/certs/cabundle.crt

Thanks to all the brilliant answers in:

How to get response SSL certificate from requests in python?

I have put together the following to attempt to take it a step further.

https://github.com/neozenith/get-ca-py

Finally

Set the configuration in pip and conda so that it knows where this CA store resides with our extra self-signed CA.

pip config set global.cert %USERPROFILE%\certs\ca-bundle.crt
conda config --set ssl_verify %USERPROFILE%\certs\ca-bundle.crt

OR

pip config set global.cert $HOME/certs/ca-bundle.crt
conda config --set ssl_verify $HOME/certs/ca-bundle.crt

THEN

pip config list
conda config --show ssl_verify

# Hot tip: use -v to show where your pip config file is...
pip config list -v

I have come up with two statements that can divide positive and negative numbers into integers and fractions without compromising accuracy (bit overflow) and speed.

x = 100.1323 # A number to be divided into integers and fractions

# The two statement to divided a number into integers and fractions
i = int(x) # A positive or negative integer
f = (x*1e17-i*1e17)/1e17 # A positive or negative fraction

E.g. 100.1323 -> 100, 0.1323 or -100.1323 -> -100, -0.1323

Speedtest

The performance test shows that the two statements are faster than math.modf, as long as they are not put into their own function or method.

If you want to see DDL for the objects, you can use

select dbms_metadata.get_ddl('OBJECT_TYPE','OBJECT_NAME','OBJECT_OWNER') 
  from dual
/

For example this will give you the DDL script for emp table.

select dbms_metadata.get_ddl('TABLE','EMP','HR') 
  from dual
/

You may need to set the long type format to big number. For packages, you need to access dba_source, user_source, all_source tables. You can query for object name and type to see what code is stored.

With JRE 8 on XP there is another way - to use MSI to deploy package.

• Install JRE 8 x86 on a PC with supported OS
• Copy c:\Users[USER]\AppData\LocalLow\Sun\Java\jre1.8.0\jre1.8.0.msi and Data1.cab to XP PC and run jre1.8.0.msi
  

or (silent way, usable in batch file etc..)

for %%I in ("*.msi") do if exist "%%I" msiexec.exe /i %%I /qn EULA=0 SKIPLICENSE=1 PROG=0 ENDDIALOG=0

I know this question was specific to JavaScript, however, there seems to be no good, clean way to ALWAYS detect when a textarea changes in all current browsers. I've learned jquery has taken care of it for us. It even handles contextual menu changes to text areas. The same syntax is used regardless of input type.

    $('div.lawyerList').on('change','textarea',function(){
      // Change occurred so count chars...
    });

or

    $('textarea').on('change',function(){
      // Change occurred so count chars...
    });

Try this.

CameraManager camManager = (CameraManager) getSystemService(Context.CAMERA_SERVICE);
    String cameraId = null; // Usually front camera is at 0 position.
    try {
        cameraId = camManager.getCameraIdList()[0];
        camManager.setTorchMode(cameraId, true);
    } catch (CameraAccessException e) {
        e.printStackTrace();
    }

The best way for converting to Numpy Array is using '.to_numpy(self, dtype=None, copy=False)'. It is new in version 0.24.0.Refrence

You can also use '.array'.Refrence

Pandas .as_matrix deprecated since version 0.23.0.

You can use COM, or P/Invoke from .Net, to open the Winspool.drv driver and send bytes directly to devices. But you don't want to do that; this typically works only for the one device on the one version of the one driver you test with, and breaks on everything else. Take this from long, painful, personal experience.

What you want to do is get a barcode font or library that draws barcodes using plain old GDI or GDI+ commands; there's one for .Net here. This works on all devices, even after Zebra changes the driver.

Why would you use it if you already knew the class and were going to cast it? Why not just do it the old fashioned way and make the class like you always make it? There's no advantage to this over the way it's done normally. Is there a way to take the text and operate on it thusly:

label1.txt = "Pizza" 
Magic(label1.txt) p = new Magic(lablel1.txt)(arg1, arg2, arg3);
p.method1();
p.method2();

If I already know its a Pizza there's no advantage to:

p = (Pizza)somefancyjunk("Pizza"); over
Pizza p = new Pizza();

but I see a huge advantage to the Magic method if it exists.

High resolution timers that provide a resolution of 1 microsecond are system-specific, so you will have to use different methods to achieve this on different OS platforms. You may be interested in checking out the following article, which implements a cross-platform C++ timer class based on the functions described below:

• [Song Ho Ahn - High Resolution Timer][1]

Windows

The Windows API provides extremely high resolution timer functions: QueryPerformanceCounter(), which returns the current elapsed ticks, and QueryPerformanceFrequency(), which returns the number of ticks per second.

Example:

#include <stdio.h>
#include <windows.h>                // for Windows APIs

int main(void)
{
    LARGE_INTEGER frequency;        // ticks per second
    LARGE_INTEGER t1, t2;           // ticks
    double elapsedTime;

    // get ticks per second
    QueryPerformanceFrequency(&frequency);

    // start timer
    QueryPerformanceCounter(&t1);

    // do something
    // ...

    // stop timer
    QueryPerformanceCounter(&t2);

    // compute and print the elapsed time in millisec
    elapsedTime = (t2.QuadPart - t1.QuadPart) * 1000.0 / frequency.QuadPart;
    printf("%f ms.\n", elapsedTime);
}

Linux, Unix, and Mac

For Unix or Linux based system, you can use gettimeofday(). This function is declared in "sys/time.h".

Example:

#include <stdio.h>
#include <sys/time.h>                // for gettimeofday()

int main(void)
{
    struct timeval t1, t2;
    double elapsedTime;

    // start timer
    gettimeofday(&t1, NULL);

    // do something
    // ...

    // stop timer
    gettimeofday(&t2, NULL);

    // compute and print the elapsed time in millisec
    elapsedTime = (t2.tv_sec - t1.tv_sec) * 1000.0;      // sec to ms
    elapsedTime += (t2.tv_usec - t1.tv_usec) / 1000.0;   // us to ms
    printf("%f ms.\n", elapsedTime);
}

To get the value from a textarea with an id you just have to do

Edited

$("#area1").val();

If you are having more than one element with the same id in the document then the HTML is invalid.

From the docs:

"a UNIQUE index permits multiple NULL values for columns that can contain NULL"

This applies to all engines but BDB.

You could also use RegExp:

function validateEmail(str) {
    return new RegExp(/([\w\.\-_]+)?\w+@[\w-_]+(\.\w+){1,}/, 'igm').test(str);
}

See the Regular Expressions guide on MDN for more info.

in addition to all the previous answers, and in case you're wondering how we're going to write dynamic property names in the Future using Computed Property Names ( ECMAScript 6 ), here's how:

var person = "John Doe";
var personId = "person_" + new Date().getTime();
var personIndex = {
    [ personId ]: person
//  ^ computed property name
};

personIndex[ personId ]; // "John Doe"

reference: Understanding ECMAScript 6 - Nickolas Zakas

By strange it can seem it works perfectly fine: date_create( '2016-02-01 + 1 day' );

echo date_create( $your_date . ' + 1 day' )->format( 'Y-m-d' );

Should do it

You Could also use this.. it works assuming 'yourimage.jpg' is in your public folder.

<img src={'./yourimage.jpg'}/>

You can do this too:

oldIFS="$IFS"
IFS=$'\n' arr=($(<file))
IFS="$oldIFS"
echo "${arr[1]}" # It will print `A Dog`.

Note:

Filename expansion still occurs. For example, if there's a line with a literal * it will expand to all the files in current folder. So use it only if your file is free of this kind of scenario.

I know this question is a bit old, but, I'm using this code since lot time ago (I've used response from @chris-go), and now, these code are obsolete with PHP 7.2

I'll post an updated version of these code (Credit for the main code are from @bigwebguy, @mike and @chris-go, all of them answers of this question):

/**
 * Replaces any parameter placeholders in a query with the value of that
 * parameter. Useful for debugging. Assumes anonymous parameters from 
 * $params are are in the same order as specified in $query
 *
 * @param string $query The sql query with parameter placeholders
 * @param array $params The array of substitution parameters
 * @return string The interpolated query
 */
public function interpolateQuery($query, $params) {
    $keys = array();
    $values = $params;

    # build a regular expression for each parameter
    foreach ($params as $key => $value) {
        if (is_string($key)) {
            $keys[] = '/:'.$key.'/';
        } else {
            $keys[] = '/[?]/';
        }

        if (is_array($value))
            $values[$key] = implode(',', $value);

        if (is_null($value))
            $values[$key] = 'NULL';
    }
    // Walk the array to see if we can add single-quotes to strings
    array_walk($values, function(&$v, $k) { if (!is_numeric($v) && $v != "NULL") $v = "\'" . $v . "\'"; });

    $query = preg_replace($keys, $values, $query, 1, $count);

    return $query;
}

Note the change on the code are on array_walk() function, replacing create_function by an anonymous function. This make these good piece of code functional and compatible with PHP 7.2 (and hope future versions too).

There is a built-in method to get the bounding rectangle: Element.getBoundingClientRect.

The result is the smallest rectangle which contains the entire element, with the read-only left, top, right, bottom, x, y, width, and height properties.

See the example below:

let innerBox = document.getElementById("myDiv").getBoundingClientRect().height;_x000D_
document.getElementById("data_box").innerHTML = "height: " + innerBox;

body {_x000D_
  margin: 0;_x000D_

.absolute {_x000D_
  position: absolute;_x000D_

You need to specify it on the methods that can throw the exceptions. You just seperate them with a ',' if it can throw more than 1 type of exception. e.g.

public interface MyInterface {
  public MyObject find(int x) throws MyExceptionA,MyExceptionB;
}

A slight improvement to Bizzard's excellent answer. Supports width-offset and/or height-offset on the element, to determine how much will be subtracted from the width/height, and prevents negative dimensions.

 <div resize height-offset="260" width-offset="100">

directive:

app.directive('resize', ['$window', function ($window) {
    return function (scope, element) {
        var w = angular.element($window);
        var heightOffset = parseInt(element.attr('height-offset'));
        var widthOffset = parseInt(element.attr('width-offset'));
        var changeHeight = function () {
            if (!isNaN(heightOffset) && w.height() - heightOffset > 0)
                element.css('height', (w.height() - heightOffset) + 'px');
            if (!isNaN(widthOffset) && w.width() - widthOffset > 0)
                element.css('width', (w.width() - widthOffset) + 'px');
        };
        w.bind('resize', function () {
            changeHeight();
        });
        changeHeight();
    }
}]);

Edit This is actually a silly way of doing it in modern browsers. CSS3 has calc, which allows the calculation to be specified in CSS, like this:

#myDiv {
 width: calc(100% - 200px);
 height: calc(100% - 120px);
}

Send XML requests with the raw data type, then set the Content-Type to text/xml.

1. After creating a request, use the dropdown to change the request type to POST.

   

2. Open the Body tab and check the data type for raw.

   

3. Open the Content-Type selection box that appears to the right and select either XML (application/xml) or XML (text/xml)

   

4. Enter your raw XML data into the input field below

   

5. Click Send to submit your XML Request to the specified server.

   

No, filter does not scan the whole stream. It's an intermediate operation, which returns a lazy stream (actually all intermediate operations return a lazy stream). To convince you, you can simply do the following test:

List<Integer> list = Arrays.asList(1, 10, 3, 7, 5);
int a = list.stream()
            .peek(num -> System.out.println("will filter " + num))
            .filter(x -> x > 5)
            .findFirst()
            .get();
System.out.println(a);

Which outputs:

will filter 1
will filter 10
10

You see that only the two first elements of the stream are actually processed.

So you can go with your approach which is perfectly fine.

This will not change the default schema in Oracle Sql Developer but I wanted to point out that it is easy to quickly view another user schema, right click the Database Connection:

Select the user to see the schema for that user

the answer is already exist above, but I would like to add some thing.. you can specify the following in your @font-face

@font-face {
  font-family: 'Name You Font';
  src: url('assets/font/xxyourfontxxx.eot');
  src: local('Cera Pro Medium'), local('CeraPro-Medium'),
  url('assets/font/xxyourfontxxx.eot?#iefix') format('embedded-opentype'),
  url('assets/font/xxyourfontxxx.woff') format('woff'),
  url('assets/font/xxyourfontxxx.ttf') format('truetype');
  font-weight: 500;
  font-style: normal;
}

So you can just indicate your fontfamily name that you already choosed

NOTE: the font-weight and font-style depend on your .woff .ttf ... files

One can achieve this using one's browser console and running

fetch('https://api.github.com/repos/[USERNAME]/[REPO]')
  .then(v => v.json()).then((function(v){
   console.log(v['size'] + "KB")
  })
)

Let's consider a practical example.

Assuming one wants to find the size of this repo using Firefox.

Open the console with Ctrl+Shift+K.

Then paste the following code

fetch('https://api.github.com/repos/goncaloperes/TimeSeries')
  .then(v => v.json()).then((function(v){
   console.log(v['size'] + "KB")
  })
)

Press enter and one will receive the size of the repo as one can see in the image bellow.

I want to share a simple approach for downloading files with JavaScript (ES6), React and a Spring Boot backend:

1. Spring boot Rest Controller
   

Resource from org.springframework.core.io.Resource

    @SneakyThrows
    @GetMapping("/files/{filename:.+}/{extraVariable}")
    @ResponseBody
    public ResponseEntity<Resource> serveFile(@PathVariable String filename, @PathVariable String extraVariable) {

        Resource file = storageService.loadAsResource(filename, extraVariable);
        return ResponseEntity.ok()
               .header(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=\"" + file.getFilename() + "\"")
               .body(file);
    }

2. React, API call using AXIOS
   

Set the responseType to arraybuffer to specify the type of data contained in the response.

export const DownloadFile = (filename, extraVariable) => {
let url = 'http://localhost:8080/files/' + filename + '/' + extraVariable;
return axios.get(url, { responseType: 'arraybuffer' }).then((response) => {
    return response;
})};

Final step > downloading
with the help of js-file-download you can trigger browser to save data to file as if it was downloaded.

DownloadFile('filename.extension', 'extraVariable').then(
(response) => {
    fileDownload(response.data, filename);
}
, (error) => {
    // ERROR 
});

In 2012 OData underwent standardization, so I'll just add an update here..

First the definitions:

REST - is an architecture of how to send messages over HTTP.

OData V4- is a specific implementation of REST, really defines the content of the messages in different formats (currently I think is AtomPub and JSON). ODataV4 follows rest principles.

For example, asp.net people will mostly use WebApi controller to serialize/deserialize objects into JSON and have javascript do something with it. The point of Odata is being able to query directly from the URL with out-of-the-box options.

You can get current href value by this code:

$(this).attr("href");

To get href value by ID

$("#mylink").attr("href");

This is how you can create a beautiful button with a bezel and rounded edges:

loginButton = UIButton(frame: CGRectMake(self.view.bounds.origin.x + (self.view.bounds.width * 0.325), self.view.bounds.origin.y + (self.view.bounds.height * 0.8), self.view.bounds.origin.x + (self.view.bounds.width * 0.35), self.view.bounds.origin.y + (self.view.bounds.height * 0.05)))
loginButton.layer.cornerRadius = 18.0
loginButton.layer.borderWidth = 2.0
loginButton.backgroundColor = UIColor.whiteColor()
loginButton.layer.borderColor = UIColor.whiteColor().CGColor
loginButton.setTitle("Login", forState: UIControlState.Normal)
loginButton.setTitleColor(UIColor(red: 24.0/100, green: 116.0/255, blue: 205.0/205, alpha: 1.0), forState: UIControlState.Normal)

Here is a way to check is virtualization is enabled or disabled by the firmware as suggested by this link in parallels.com.

How to check that Intel VT-x is supported in CPU:

1. Open Terminal application from Application/Utilities

2. Copy/paste command bellow

sysctl -a | grep machdep.cpu.features

3. You may see output similar to:

Mac:~ user$ sysctl -a | grep machdep.cpu.features kern.exec: unknown type returned machdep.cpu.features: FPU VME DE PSE TSC MSR PAE MCE CX8 APIC SEP MTRR PGE MCA CMOV PAT CLFSH DS ACPI MMX FXSR SSE SSE2 SS HTT TM SSE3 MON VMX EST TM2 TPR PDCM

If you see VMX entry then CPU supports Intel VT-x feature, but it still may be disabled.

Refer to this link on Apple.com to enable hardware support for virtualization:

The simple way to solve the problem is to use ComparisonChain from Guava http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/collect/ComparisonChain.html

private static Comparator<String> stringAlphabeticalComparator = new Comparator<String>() {
        public int compare(String str1, String str2) {
            return ComparisonChain.start().
                                compare(str1,str2, String.CASE_INSENSITIVE_ORDER).
                                compare(str1,str2).
                                result();
         }
 };
Collections.sort(list, stringAlphabeticalComparator);

The first comparator from the chain will sort strings according to the case insensitive order, and the second comparator will sort strings according to the case insensitive order. As excepted strings appear in the result according to the alphabetical order:

"AA","Aa","aa","Development","development"

have also a site where base - tag is used, and the problem described occured. ( after upgrading jquery ), was able to fix it by having tab urls like this:

<li><a href="{$smarty.server.REQUEST_URI}#tab_1"></li>

this makes them "local"

references i used:

http://bugs.jqueryui.com/ticket/7822 http://htmlhelp.com/reference/html40/head/base.html http://tjvantoll.com/2013/02/17/using-jquery-ui-tabs-with-the-base-tag/

I too experienced the same issues with the border formatting not being shown using entrophy's code but a few little fixes and now the table is expandable and displays all css styling rules you may add.

to css add:

#maintable{width: 100%}    

then here is the new javascript:

    function moveScroll(){
    var scroll = $(window).scrollTop();
    var anchor_top = $("#maintable").offset().top;
    var anchor_bottom = $("#bottom_anchor").offset().top;
    if (scroll > anchor_top && scroll < anchor_bottom) {
        clone_table = $("#clone");
        if(clone_table.length === 0) {          
            clone_table = $("#maintable").clone();
            clone_table.attr({id: "clone"})
            .css({
                position: "fixed",
                "pointer-events": "none",
                 top:0
            })
            .width($("#maintable").width());

            $("#table-container").append(clone_table);
            // dont hide the whole table or you lose border style & 
            // actively match the inline width to the #maintable width if the 
            // container holding the table (window, iframe, div) changes width          
            $("#clone").width($("#maintable").width());
            // only the clone thead remains visible
            $("#clone thead").css({
                visibility:"visible"
            });
            // clone tbody is hidden
            $("#clone tbody").css({
                visibility:"hidden"
            });
            // add support for a tfoot element
            // and hide its cloned version too
            var footEl = $("#clone tfoot");
            if(footEl.length){
                footEl.css({
                    visibility:"hidden"
                });
            }
        }
    } 
    else {
        $("#clone").remove();
    }
}
$(window).scroll(moveScroll);

Declare a global var:

var td

Then select your guiena pig <td> getting it by its id, if you want to change all of them then

window.onload = function () {
  td = document.getElementsByTagName("td"); 
}

Make a function to be triggered and a loop to change all of your desired td's

function trigger() {
    for(var x = 0; x < td.length; x++) { 
      td[x].className = "yournewclass"; 
    }
}

Go to your CSS Sheet:

.yournewclass:hover { background-color: #00ff00; }

And that is it, with this you are able to to make all your <td> tags get a background-color: #00ff00; when hovered by changing its css propriety directly (switching between css classes).

If you would like it to go back to first option try this:

   document.getElementById("select").selectedIndex = 0;

For anyone running Windows 10 1607 and looking for .net 4.7. Disregard all of the above.

It's not in the Registry, C:\Windows\Microsoft.NET folder or the Installed Programs list or the WMIC display of that same list.

Look for "installed updates" KB3186568.

That's pretty much all you need:

mysql> select * from t;
+------+-------+
| id   | data  |
+------+-------+
|    1 | max   |
|    2 | linda |
|    3 | sam   |
|    4 | henry |
+------+-------+
4 rows in set (0.02 sec)

mysql> update t set data=concat(data, 'a');
Query OK, 4 rows affected (0.01 sec)
Rows matched: 4  Changed: 4  Warnings: 0

mysql> select * from t;
+------+--------+
| id   | data   |
+------+--------+
|    1 | maxa   |
|    2 | lindaa |
|    3 | sama   |
|    4 | henrya |
+------+--------+
4 rows in set (0.00 sec)

Not sure why you'd be having trouble, though I am testing this on 5.1.41

Actually I wanted same alike thing, To get one year backward date, for a given date! :-)

With the hint of above answer from @mohammad mohsenipur I got to the following link, via his given link!

Luckily, there is a method same as date_add method, named date_sub method! :-) I do the following to get done what I wanted!

$date = date_create('2000-01-01');
date_sub($date, date_interval_create_from_date_string('1 years'));
echo date_format($date, 'Y-m-d');

Hopes this answer will help somebody too! :-)

Good luck guys!

StringUtils is a utility class from Apache commons-lang (many libraries have it but this is the most common library). You need to download the jar and add it to your applications classpath.

Assuming the MyEjbProject is not another Maven Project you own or want to build with maven, you could use system dependencies to link to the existing jar file of the project like so

<project>
   ...
   <dependencies>
      <dependency>
         <groupId>yourgroup</groupId>
         <artifactId>myejbproject</artifactId>
         <version>2.0</version>
         <scope>system</scope>
         <systemPath>path/to/myejbproject.jar</systemPath>
      </dependency>
   </dependencies>
   ...
</project>

That said it is usually the better (and preferred way) to install the package to the repository either by making it a maven project and building it or installing it the way you already seem to do.

If they are, however, dependent on each other, you can always create a separate parent project (has to be a "pom" project) declaring the two other projects as its "modules". (The child projects would not have to declare the third project as their parent). As a consequence you'd get a new directory for the new parent project, where you'd also quite probably put the two independent projects like this:

parent
|- pom.xml
|- MyEJBProject
|   `- pom.xml
`- MyWarProject
    `- pom.xml

The parent project would get a "modules" section to name all the child modules. The aggregator would then use the dependencies in the child modules to actually find out the order in which the projects are to be built)

<project>
   ...
   <artifactId>myparentproject</artifactId>
   <groupId>...</groupId>
   <version>...</version>

   <packaging>pom</packaging>
   ...
   <modules>
     <module>MyEJBModule</module>
     <module>MyWarModule</module>
   </modules>
   ...
</project>

That way the projects can relate to each other but (once they are installed in the local repository) still be used independently as artifacts in other projects

Finally, if your projects are not in related directories, you might try to give them as relative modules:

filesystem
 |- mywarproject
 |   `pom.xml
 |- myejbproject
 |   `pom.xml
 `- parent
     `pom.xml

now you could just do this (worked in maven 2, just tried it):

<!--parent-->
<project>
  <modules>
    <module>../mywarproject</module>
    <module>../myejbproject</module>
  </modules>
</project>

If you don't want to modify the registry or app.config files, an alternate way is to create a simple .NET 4 console app that mimicks what PowerShell.exe does and hosts the PowerShell ConsoleShell.

See Option 2 – Hosting Windows PowerShell yourself

First, add a reference to the System.Management.Automation and Microsoft.PowerShell.ConsoleHost assemblies which can be found under %programfiles%\Reference Assemblies\Microsoft\WindowsPowerShell\v1.0

Then use the following code:

using System;
using System.Management.Automation.Runspaces;
using Microsoft.PowerShell;

namespace PSHostCLRv4
{
    class Program
    {
        static int Main(string[] args)
        {
            var config = RunspaceConfiguration.Create();
                return ConsoleShell.Start(
                config,
                "Windows PowerShell - Hosted on CLR v4\nCopyright (C) 2010 Microsoft Corporation. All rights reserved.",
                "",
                args
            );
        }
    }
}

On a 64-bit system you have to make sure that both the Tomcat application and the JDK are the same architecture: either both are x86 or x64.

In case you want to change the Tomcat instance to x64 you might have to download the tomcat8.exe or tomcat9.exe and the tcnative-1.dll with the appropriate x64 versions. You can get those at http://svn.apache.org/viewvc/tomcat/.

Alternatively you can point Tomcat to the x86 JDK by changing the Java Virtual Machine path in the Tomcat config.

In my case, I was looking for a solution that allows one of the navbar items to be right aligned. In order to do this, you must add style="width:100%;" to the <ul class="navbar-nav"> and then add the ml-auto class to your navbar item.

The MySQL extension is the oldest of the three and was the original way that developers used to communicate with MySQL. This extension is now being deprecated in favor of the other two alternatives because of improvements made in newer releases of both PHP and MySQL.

• MySQLi is the 'improved' extension for working with MySQL databases. It takes advantage of features that are available in newer versions of the MySQL server, exposes both a function-oriented and an object-oriented interface to the developer and a does few other nifty things.

• PDO offers an API that consolidates most of the functionality that was previously spread across the major database access extensions, i.e. MySQL, PostgreSQL, SQLite, MSSQL, etc. The interface exposes high-level objects for the programmer to work with database connections, queries and result sets, and low-level drivers perform communication and resource handling with the database server. A lot of discussion and work is going into PDO and it’s considered the appropriate method of working with databases in modern, professional code.

If you need an asynchronous-friendly version of Array.forEach and similar, they're available in the Node.js 'async' module: http://github.com/caolan/async ...as a bonus this module also works in the browser.

async.each(openFiles, saveFile, function(err){
    // if any of the saves produced an error, err would equal that error
});

I just ran the following command:

php artisan passport:install

I was using passport to run my application completely based on API's and Vue.js. Laravel worked fine but everytime i tried to login via my API i would get the error. After running the command and updating the client_id and client_secret on my Laravel files then pushed the new updates to the live server, the problem was solved. In my user model i have a script as follows:

public function generateToken($request)
{
    $http = new \GuzzleHttp\Client();
    $response = $http->post(URL::to('/').'/oauth/token', [
        'form_params' => [
            'grant_type' => 'password',
            'client_id' => '6',
            'client_secret' => 'x3yhgWVqF8sSaMev4JI3yvsVxfbgkfRJmqzlpiMQ',
            'username' => $this->email,
            'password' => $request->input('password'),
            'scope' => '',
        ],
    ]);
    //  Lets get an array instead of a stdObject so that we can return without errors
    $response = json_decode($response->getBody(), true);

    return oq_api_notify([
                'auth' => $response,                                        //  API ACCESS TOKEN
                'user' => $this->load(['settings'])->toArray(),
            ], 201);
}

I just updated the client_id and client_secret only then saved. Since the passport command gives you two client keys:

1) Personal access client (client_id & client_secret)

2) Password grant client (client_id & client_secret)

I used the Password grant client. Hopes this helps someone out there :)

How about converting to lowercase first? you can use string.lower().

Use another flex container to fix the min-height issue in IE10 and IE11:

HTML

<div class="ie-fixMinHeight">
    <div id="page">
        <div id="header"></div>
        <div id="content"></div>
        <div id="footer"></div>
    </div>
</div>

CSS

.ie-fixMinHeight {
    display:flex;
}

#page {
    min-height:100vh;
    width:100%;
    display:flex;
    flex-direction:column;
}

#content {
    flex-grow:1;
}

See a working demo.

• Don't use flexbox layout directly on body because it screws up elements inserted via jQuery plugins (autocomplete, popup, etc.).
• Don't use height:100% or height:100vh on your container because the footer will stick at the bottom of window and won't adapt to long content.
• Use flex-grow:1 rather than flex:1 cause IE10 and IE11 default values for flex are 0 0 auto and not 0 1 auto.

The accepted answer is correct, but I prefer:

@{int count = 0;} 
@foreach (var item in Model.Resources) 
{ 
    @Html.Raw(count <= 3 ? "<div class=\"resource-row\">" : "")  
    // some code 
    @Html.Raw(count <= 3 ? "</div>" : "")  
    @(count++)
} 

I hope this inspires someone, even though I'm late to the party.

I think you are not configured properly,

if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(use the above send mail path only and it will work)

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]

Now you have done!! create php file with mail function and send mail from localhost.

Update

First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()).

You can set the following settings in your PHP.ini:

ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");

private async void Ping_Click(object sender, RoutedEventArgs e)
{
    Ping pingSender = new Ping();
    string host = @"stackoverflow.com";
    await Task.Run(() =>{
         PingReply reply = pingSender.Send(host);
         if (reply.Status == IPStatus.Success)
         {
            Console.WriteLine("Address: {0}", reply.Address.ToString());
            Console.WriteLine("RoundTrip time: {0}", reply.RoundtripTime);
            Console.WriteLine("Time to live: {0}", reply.Options.Ttl);
            Console.WriteLine("Don't fragment: {0}", reply.Options.DontFragment);
            Console.WriteLine("Buffer size: {0}", reply.Buffer.Length);
         }
         else
         {
            Console.WriteLine("Address: {0}", reply.Status);
         }
   });           
}

This should do it:

SELECT report_id, computer_id, date_entered
FROM reports AS a
WHERE date_entered = (
    SELECT MAX(date_entered)
    FROM reports AS b
    WHERE a.report_id = b.report_id
      AND a.computer_id = b.computer_id
)

You can give it a property display block; so it will behave like a div and have its own line

CSS:

.feature_desc {
   display: block;
   ....
}

No, you can't control the animation of the images.

You would need two versions of each image, one that is animated, and one that's not. On hover you can easily change from one image to another.

Example:

$(function(){
  $('img').each(function(e){
    var src = $(e).attr('src');
    $(e).hover(function(){
      $(this).attr('src', src.replace('.gif', '_anim.gif'));
    }, function(){
      $(this).attr('src', src);
    });
  });
});

Update:

Time goes by, and possibilities change. As kritzikatzi pointed out, having two versions of the image is not the only option, you can apparently use a canvas element to create a copy of the first frame of the animation. Note that this doesn't work in all browsers, IE 8 for example doesn't support the canvas element.

Either modify the pattern beforehand so that it only matches the entire string:

var r = /^a$/

or check afterward whether the pattern matched the whole string:

function matchExact(r, str) {
   var match = str.match(r);
   return match && str === match[0];
}

Following line in above code is not working

DB_PASSWORD=$(eval echo ${DB_PASSWORD} | base64 --decode)

Correct line is:

DB_PASSWORD=`echo $PASSWORD|base64 -d`

And save the password in other file as PASSWORD.

Yes, Daniel is correct, but to expand upon his answer, your primary app component would need to have a navbar component within it. That way, when you render the primary app (any page under the '/' path), it would also display the navbar. I am guessing that you wouldn't want your login page to display the navbar, so that shouldn't be a nested component, and should instead be by itself. So your routes would end up looking something like this:

<Router>
  <Route path="/" component={App}>
    <Route path="page1" component={Page1} />
    <Route path="page2" component={Page2} />
  </Route>
  <Route path="/login" component={Login} />
</Router>

And the other components would look something like this:

var NavBar = React.createClass({
  render() {
    return (
      <div>
        <ul>
          <a onClick={() => history.push('page1') }>Page 1</a>
          <a onClick={() => history.push('page2') }>Page 2</a>
        </ul>
      </div>
    )
  }
});

var App = React.createClass({
  render() {
    return (
      <div>
        <NavBar />
        <div>Other Content</div>
        {this.props.children}
      </div>
    )
  }
});

You can simply use

document.getElementById("elementID").outerHTML="";

It works in all browsers, even on Internet Explorer.

Very simple: no color, no opacity:

rgba(0, 0, 0, 0);

If you want to search for documents that belong to a specific month, make sure to query like this:

// Anything greater than this month and less than the next month
db.posts.find({created_on: {$gte: new Date(2015, 6, 1), $lt: new Date(2015, 7, 1)}});

Avoid quering like below as much as possible.

// This may not find document with date as the last date of the month
db.posts.find({created_on: {$gte: new Date(2015, 6, 1), $lt: new Date(2015, 6, 30)}});

// don't do this too
db.posts.find({created_on: {$gte: new Date(2015, 6, 1), $lte: new Date(2015, 6, 30)}});

use:

NSLog(@"%f",[[UIScreen mainScreen] bounds].size.width) ;

Take the width of the table and divide it by the number of cell ().

PerformanceTable {width:500px;}    
PerformanceTable.td {width:100px;}

If the table dynamically widens or shrinks you could dynamically increase the cell size with a little javascript.

If you're on Windows then it's a total no-brainer: Get Visual C++ Express.

Sharing my case, hope that will help.

In my situation inside MY_PROJ.Database->MY_PROJ.Database.sqlproj I had to put this:

<Build Include="dbo\Tables\MyTableGeneratingScript.sql" />

I always advocate Joda-time. Here's why.

1. the API is consistent and intuitive. Unlike the java.util.Date/Calendar APIs
2. it doesn't suffer from threading issues, unlike java.text.SimpleDateFormat etc. (I've seen numerous client issues relating to not realising that the standard date/time formatting is not thread-safe)
3. it's the basis of the new Java date/time APIs (JSR310, scheduled for Java 8. So you'll be using APIs that will become core Java APIs.

EDIT: The Java date/time classes introduced with Java 8 are now the preferred solution, if you can migrate to Java 8

You need to login to your mysql terminal first using mysql -u username -p password

Then use this:

SELECT @@sql_mode; or SELECT @@GLOBAL.sql_mode;

output will be like this:

STRICT_TRANS_TABLES,STRICT_ALL_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,TRADITIONAL,NO_AUTO_CREATE_USER,NO_ENGINE_SUB

You can also set sql mode by this:

SET GLOBAL sql_mode=TRADITIONAL;

This is supposed to print the ASCII value of the character, as %d is the escape sequence for an integer. So the value given as argument of printf is taken as integer when printed.

char ch = 'a';
printf("%d", ch);

Same holds for printf("%d", '\0');, where the NULL character is interpreted as the 0 integer.

Finally, sizeof('\n') is 4 because in C, this notation for characters stands for the corresponding ASCII integer. So '\n' is the same as 10 as an integer.

It all depends on the interpretation you give to the bytes.

A quick and simple solution is for the AndroidManifest.xml file, add the following for each activity that you wish to force to landscape mode:

android:screenOrientation="landscape"

Looks like you've got some answers to this, however I think there is something worth mentioning here that will greatly simplify your code. jQuery introduced the $.when in v1.5. It looks like:

$.when($.ajax(...), $.ajax(...)).then(function (resp1, resp2) {
    //this callback will be fired once all ajax calls have finished.
});

Didn't see it mentioned here, hope it helps.

You can simply place multiple name together separated by a white space like

C:\Users\Dell>pip install markdown django-filter

#c:\Users\Dell is path in my pc this can be anything on yours

this installed markdown and django-filter on my device.

A view helps us in get rid of utilizing database space all the time. If you create a table it is stored in database and holds some space throughout its existence. Instead view is utilized when a query runs hence saving the db space. And we cannot create big tables all the time joining different tables though we could but its depends how big the table is to save the space. So view just temporarily create a table with joining different table at the run time. Experts,Please correct me if I am wrong.

angular.module('myapp', ['myapp.filters', 'myapp.services', 'myapp.directives']).

                return '/pages/' + urlattr.name + '.html';
            },
            controller: 'CMSController'
        });
    }
]);

• Adding * let you work with multiple levels of directories dynamically. Example: /page/cars/selling/list will be catch on this provider

From the docs (1.3.0):

"If templateUrl is a function, it will be called with the following parameters:

{Array.} - route parameters extracted from the current $location.path() by applying the current route"

Also

when(path, route) : Method

• path can contain named groups starting with a colon and ending with a star: e.g.:name*. All characters are eagerly stored in $routeParams under the given name when the route matches.

Assuming a C-style array a of size N, with elements of a type implicitly convertible from 0, the following sets all the elements to values constructed from 0.

std::fill(a, a+N, 0);

Note that this is not the same as "emptying" or "clearing".

Edit: Following james Kanze's suggestion, in C++11 you could use the more idiomatic alternative

std::fill( std::begin( a ), std::end( a ), 0 );

In the absence of C++11, you could roll out your own solution along these lines:

template <typename T, std::size_t N> T* end_(T(&arr)[N]) { return arr + N; }

template <typename T, std::size_t N> T* begin_(T(&arr)[N]) { return arr; }

std::fill( begin_( a ), end_( a ), 0 );

Here's some simple code to add a time out to your recv function using poll in C:

switch (ret) {
    case -1:

        break;
    case 0:
        // Timeout

I feel compelled to provide a counterpoint to Ashwini Chaudhary's answer. Despite appearances, the two-argument form of the round function does not round a Python float to a given number of decimal places, and it's often not the solution you want, even when you think it is. Let me explain...

The ability to round a (Python) float to some number of decimal places is something that's frequently requested, but turns out to be rarely what's actually needed. The beguilingly simple answer round(x, number_of_places) is something of an attractive nuisance: it looks as though it does what you want, but thanks to the fact that Python floats are stored internally in binary, it's doing something rather subtler. Consider the following example:

>>> round(52.15, 1)
52.1

With a naive understanding of what round does, this looks wrong: surely it should be rounding up to 52.2 rather than down to 52.1? To understand why such behaviours can't be relied upon, you need to appreciate that while this looks like a simple decimal-to-decimal operation, it's far from simple.

So here's what's really happening in the example above. (deep breath) We're displaying a decimal representation of the nearest binary floating-point number to the nearest n-digits-after-the-point decimal number to a binary floating-point approximation of a numeric literal written in decimal. So to get from the original numeric literal to the displayed output, the underlying machinery has made four separate conversions between binary and decimal formats, two in each direction. Breaking it down (and with the usual disclaimers about assuming IEEE 754 binary64 format, round-ties-to-even rounding, and IEEE 754 rules):

1. First the numeric literal 52.15 gets parsed and converted to a Python float. The actual number stored is 7339460017730355 * 2**-47, or 52.14999999999999857891452847979962825775146484375.

2. Internally as the first step of the round operation, Python computes the closest 1-digit-after-the-point decimal string to the stored number. Since that stored number is a touch under the original value of 52.15, we end up rounding down and getting a string 52.1. This explains why we're getting 52.1 as the final output instead of 52.2.

3. Then in the second step of the round operation, Python turns that string back into a float, getting the closest binary floating-point number to 52.1, which is now 7332423143312589 * 2**-47, or 52.10000000000000142108547152020037174224853515625.

4. Finally, as part of Python's read-eval-print loop (REPL), the floating-point value is displayed (in decimal). That involves converting the binary value back to a decimal string, getting 52.1 as the final output.

In Python 2.7 and later, we have the pleasant situation that the two conversions in step 3 and 4 cancel each other out. That's due to Python's choice of repr implementation, which produces the shortest decimal value guaranteed to round correctly to the actual float. One consequence of that choice is that if you start with any (not too large, not too small) decimal literal with 15 or fewer significant digits then the corresponding float will be displayed showing those exact same digits:

>>> x = 15.34509809234
>>> x
15.34509809234

Unfortunately, this furthers the illusion that Python is storing values in decimal. Not so in Python 2.6, though! Here's the original example executed in Python 2.6:

>>> round(52.15, 1)
52.200000000000003

Not only do we round in the opposite direction, getting 52.2 instead of 52.1, but the displayed value doesn't even print as 52.2! This behaviour has caused numerous reports to the Python bug tracker along the lines of "round is broken!". But it's not round that's broken, it's user expectations. (Okay, okay, round is a little bit broken in Python 2.6, in that it doesn't use correct rounding.)

Short version: if you're using two-argument round, and you're expecting predictable behaviour from a binary approximation to a decimal round of a binary approximation to a decimal halfway case, you're asking for trouble.

So enough with the "two-argument round is bad" argument. What should you be using instead? There are a few possibilities, depending on what you're trying to do.

• If you're rounding for display purposes, then you don't want a float result at all; you want a string. In that case the answer is to use string formatting:

  >>> format(66.66666666666, '.4f')
  '66.6667'
  >>> format(1.29578293, '.6f')
  '1.295783'
  

  Even then, one has to be aware of the internal binary representation in order not to be surprised by the behaviour of apparent decimal halfway cases.

  >>> format(52.15, '.1f')
  '52.1'
  

• If you're operating in a context where it matters which direction decimal halfway cases are rounded (for example, in some financial contexts), you might want to represent your numbers using the Decimal type. Doing a decimal round on the Decimal type makes a lot more sense than on a binary type (equally, rounding to a fixed number of binary places makes perfect sense on a binary type). Moreover, the decimal module gives you better control of the rounding mode. In Python 3, round does the job directly. In Python 2, you need the quantize method.

  >>> Decimal('66.66666666666').quantize(Decimal('1e-4'))
  Decimal('66.6667')
  >>> Decimal('1.29578293').quantize(Decimal('1e-6'))
  Decimal('1.295783')
  

• In rare cases, the two-argument version of round really is what you want: perhaps you're binning floats into bins of size 0.01, and you don't particularly care which way border cases go. However, these cases are rare, and it's difficult to justify the existence of the two-argument version of the round builtin based on those cases alone.

The post needs an update after the links option is deprecated.

Basically, links is no longer needed because its main purpose, making container reachable by another by adding environment variable, is included implicitly with network. When containers are placed in the same network, they are reachable by each other using their container name and other alias as host.

For docker run, --link is also deprecated and should be replaced by a custom network.

docker network create mynet
docker run -d --net mynet --name container1 my_image
docker run -it --net mynet --name container1 another_image

depends_on expresses start order (and implicitly image pulling order), which was a good side effect of links.

Using the .loc[] accessor:

In [25]: a.loc[a['c1'] == 8].index[0]
Out[25]: 4

Can also use the get_loc() by setting 'c1' as the index. This will not change the original dataframe.

In [17]: a.set_index('c1').index.get_loc(8)
Out[17]: 4

GetType() exists on every single framework type, because it is defined on the base object type. So, regardless of the type itself, you can use it to return the underlying Type

So, all you need to do is:

u.GetType() == t

I think this is the problem

A little background

Traceview is a graphical viewer for execution logs that you create by using the Debug class to log tracing information in your code. Traceview can help you debug your application and profile its performance. Enabling it creates a .trace file in the sdcard root folder which can then be extracted by ADB and processed by traceview bat file for processing. It also can get added by the DDMS.

It is a system used internally by the logger. In general unless you are using traceview to extract the trace file this error shouldnt bother you. You should look at error/logs directly related to your application

How do I enable it:

There are two ways to generate trace logs:

1. Include the Debug class in your code and call its methods such as startMethodTracing() and stopMethodTracing(), to start and stop logging of trace information to disk. This option is very precise because you can specify exactly where to start and stop logging trace data in your code.

2. Use the method profiling feature of DDMS to generate trace logs. This option is less precise because you do not modify code, but rather specify when to start and stop logging with DDMS. Although you have less control on exactly where logging starts and stops, this option is useful if you don't have access to the application's code, or if you do not need precise log timing.

But the following restrictions exist for the above

If you are using the Debug class, your application must have permission to write to external storage (WRITE_EXTERNAL_STORAGE).

If you are using DDMS: Android 2.1 and earlier devices must have an SD card present and your application must have permission to write to the SD card. Android 2.2 and later devices do not need an SD card. The trace log files are streamed directly to your development machine.

So in essence the traceFile access requires two things

1.) Permission to write a trace log file i.e. WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE for good measure

2.) An emulator with an SDCard attached with sufficient space. The doc doesnt say if this is only for DDMS but also for debug, so I am assuming this is also true for debugging via the application.

What do I do with this error:

Now the error is essentially a fall out of either not having the sdcard path to create a tracefile or not having permission to access it. This is an old thread, but the dev behind the bounty, check if are meeting the two prerequisites. You can then go search for the .trace file in the sdcard folder in your emulator. If it exists it shouldn't be giving you this problem, if it doesnt try creating it by adding the startMethodTracing to your app.
I'm not sure why it automatically looks for this file when the logger kicks in. I think when an error/log event occurs , the logger internally tries to write to trace file and does not find it, in which case it throws the error.Having scoured through the docs, I don't find too many references to why this is automatically on. But in general this doesn't affect you directly, you should check direct application logs/errors. Also as an aside Android 2.2 and later devices do not need an SD card for DDMS trace logging. The trace log files are streamed directly to your development machine.

Additional information on Traceview:

Copying Trace Files to a Host Machine

After your application has run and the system has created your trace files .trace on a device or emulator, you must copy those files to your development computer. You can use adb pull to copy the files. Here's an example that shows how to copy an example file, calc.trace, from the default location on the emulator to the /tmp directory on the emulator host machine:

adb pull /sdcard/calc.trace /tmp Viewing Trace Files in Traceview To run Traceview and view the trace files, enter traceview . For example, to run Traceview on the example files copied in the previous section, use:

traceview /tmp/calc Note: If you are trying to view the trace logs of an application that is built with ProGuard enabled (release mode build), some method and member names might be obfuscated. You can use the Proguard mapping.txt file to figure out the original unobfuscated names. For more information on this file, see the Proguard documentation.

I think any other answer regarding positioning of oncreate statements or removing uses-sdk are not related, but this is Android and I could be wrong. Would be useful to redirect this question to an android engineer or post it as a bug

After a some research i found the way to bypass ssl error Trust anchor for certification path not found. This might be not a good way to do but you can use it for a testing purpose.

 private HttpsURLConnection httpsUrlConnection( URL urlDownload) throws Exception {
  HttpsURLConnection connection=null;
        TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return null;
            }

            @SuppressLint("TrustAllX509TrustManager")
            public void checkClientTrusted(X509Certificate[] certs, String authType) {

        SSLSocketFactory sslSocketFactory = sc.getSocketFactory();

        connection = (HttpsURLConnection) urlDownload.openConnection();

Use following in your CSS

div {
    -webkit-transform: rotate(90deg); /* Safari and Chrome */
    -moz-transform: rotate(90deg);   /* Firefox */
    -ms-transform: rotate(90deg);   /* IE 9 */
    -o-transform: rotate(90deg);   /* Opera */
    transform: rotate(90deg);
} 

My solution was to switch all datetime columns to datetime2, and use datetime2 for any new columns. In other words make EF use datetime2 by default. Add this to the OnModelCreating method on your context:

modelBuilder.Properties<DateTime>().Configure(c => c.HasColumnType("datetime2"));

That will get all the DateTime and DateTime? properties on all your entities.

Prior to adding the Ajax.BeginForm. Add below scripts to your project in the order mentioned,

1. jquery-1.7.1.min.js
2. jquery.unobtrusive-ajax.min.js

Only these two are enough for performing Ajax operation.

Extending from the correct answer of Andrey-Egorov using .executeScript() to conclude my own question example:

inputField = driver.findElement(webdriver.By.id('gbqfq'));
driver.executeScript("arguments[0].setAttribute('value', '" + longstring +"')", inputField);

Step-1: Your Model class

public class RechargeMobileViewModel
    {
        public string CustomerFullName { get; set; }
        public string TelecomSubscriber { get; set; }
        public int TotalAmount { get; set; }
        public string MobileNumber { get; set; }
        public int Month { get; set; }
        public List<SelectListItem> getAllDaysList { get; set; }

        // Define the list which you have to show in Drop down List
        public List<SelectListItem> getAllWeekDaysList()
        {
            List<SelectListItem> myList = new List<SelectListItem>();
            var data = new[]{
                 new SelectListItem{ Value="1",Text="Monday"},
                 new SelectListItem{ Value="2",Text="Tuesday"},
                 new SelectListItem{ Value="3",Text="Wednesday"},
                 new SelectListItem{ Value="4",Text="Thrusday"},
                 new SelectListItem{ Value="5",Text="Friday"},
                 new SelectListItem{ Value="6",Text="Saturday"},
                 new SelectListItem{ Value="7",Text="Sunday"},
             };
            myList = data.ToList();
            return myList;
        }
}

Step-2: Call this method to fill Drop down in your controller Action

namespace MvcVariousApplication.Controllers
    {
        public class HomeController : Controller
        {
            public ActionResult Index()
            {
              RechargeMobileViewModel objModel = new RechargeMobileViewModel();
                objModel.getAllDaysList = objModel.getAllWeekDaysList();  
                return View(objModel);
            }
    }
    }

Step-3: Fill your Drop-Down List of View as follows

 @model MvcVariousApplication.Models.RechargeMobileViewModel
    @{
        ViewBag.Title = "Contact";
    }
    @Html.LabelFor(model=> model.CustomerFullName)
    @Html.TextBoxFor(model => model.CustomerFullName)

    @Html.LabelFor(model => model.MobileNumber)
    @Html.TextBoxFor(model => model.MobileNumber)

    @Html.LabelFor(model => model.TelecomSubscriber)
    @Html.TextBoxFor(model => model.TelecomSubscriber)

    @Html.LabelFor(model => model.TotalAmount)
    @Html.TextBoxFor(model => model.TotalAmount)

    @Html.LabelFor(model => model.Month)
    @Html.DropDownListFor(model => model.Month, new SelectList(Model.getAllDaysList, "Value", "Text"), "-Select Day-")

Since JSF 2.3 all the bean scopes defined in package javax.faces.bean package have been deprecated to align the scopes with CDI. Moreover they're only applicable if your bean is using @ManagedBean annotation. If you are using JSF versions below 2.3 refer to the legacy answer at the end.

From JSF 2.3 here are scopes that can be used on JSF Backing Beans:

1. @javax.enterprise.context.ApplicationScoped: The application scope persists for the entire duration of the web application. That scope is shared among all requests and all sessions. This is useful when you have data for whole application.

2. @javax.enterprise.context.SessionScoped: The session scope persists from the time that a session is established until session termination. The session context is shared between all requests that occur in the same HTTP session. This is useful when you wont to save data for a specific client for a particular session.

3. @javax.enterprise.context.ConversationScoped: The conversation scope persists as log as the bean lives. The scope provides 2 methods: Conversation.begin() and Conversation.end(). These methods should called explicitly, either to start or end the life of a bean.

4. @javax.enterprise.context.RequestScoped: The request scope is short-lived. It starts when an HTTP request is submitted and ends after the response is sent back to the client. If you place a managed bean into request scope, a new instance is created with each request. It is worth considering request scope if you are concerned about the cost of session scope storage.

5. @javax.faces.flow.FlowScoped: The Flow scope persists as long as the Flow lives. A flow may be defined as a contained set of pages (or views) that define a unit of work. Flow scoped been is active as long as user navigates with in the Flow.

6. @javax.faces.view.ViewScoped: A bean in view scope persists while the same JSF page is redisplayed. As soon as the user navigates to a different page, the bean goes out of scope.

The following legacy answer applies JSF version before 2.3

As of JSF 2.x there are 4 Bean Scopes:

• @SessionScoped
• @RequestScoped
• @ApplicationScoped
• @ViewScoped

Session Scope: The session scope persists from the time that a session is established until session termination. A session terminates if the web application invokes the invalidate method on the HttpSession object, or if it times out.

RequestScope: The request scope is short-lived. It starts when an HTTP request is submitted and ends after the response is sent back to the client. If you place a managed bean into request scope, a new instance is created with each request. It is worth considering request scope if you are concerned about the cost of session scope storage.

ApplicationScope: The application scope persists for the entire duration of the web application. That scope is shared among all requests and all sessions. You place managed beans into the application scope if a single bean should be shared among all instances of a web application. The bean is constructed when it is first requested by any user of the application, and it stays alive until the web application is removed from the application server.

ViewScope: View scope was added in JSF 2.0. A bean in view scope persists while the same JSF page is redisplayed. (The JSF specification uses the term view for a JSF page.) As soon as the user navigates to a different page, the bean goes out of scope.

Choose the scope you based on your requirement.

For Java 11 you can use new HTTP client:

 HttpClient client = HttpClient.newHttpClient();
    HttpRequest request = HttpRequest.newBuilder()
        .uri(URI.create("http://localhost/api"))
        .header("Content-Type", "application/json")
        .POST(ofInputStream(() -> getClass().getResourceAsStream(
            "/some-data.json")))
        .build();

    client.sendAsync(request, BodyHandlers.ofString())
        .thenApply(HttpResponse::body)
        .thenAccept(System.out::println)
        .join();

You can use publisher from InputStream, String, File. Converting JSON to the String or IS you can with Jackson.

You can also use DateTime class:

$time1 = new DateTime('09:00:59');
$time2 = new DateTime('09:01:00');
$interval = $time1->diff($time2);
echo $interval->format('%s second(s)');

Result:

1 second(s)

To test whether a file exists in .NET, you can use

System.IO.File.Exists (String)

If anyone like me is searching to read only a specific line, example only line 18 here is the code:

filename = "C:\log.log"

Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)

For i = 1 to 17
    f.ReadLine
Next

strLine = f.ReadLine
Wscript.Echo strLine

f.Close

Your code is creating an array of function pointers. Try

char* a[size];

or

char a[size1][size2];

instead.

See wikibooks to arrays and pointers

• How long did it take OOP to get understood by the average corporate programmer...?
• I was taught functional programming at Utrecht University in - I think - 1994 and only see it start to catch on "in the real world" in the last couple of years.
• There is no such thing as a "simple application". ;-)

I think that (approaching) side effect free programming for some key parts of software will be essential when we start to get more and more cores in our hardware. Give functional programming a bit more time. And the functional sprinkling in current and future versions of C# will go a long way in preparing those corporate programmers for functional programming without them even realising it...

In Kotlin, if you don't want to create an extra class just for setting one value, you can create anonymous class from LayoutManager:

recyclerView.layoutManager = object : LinearLayoutManager(context) {
    override fun canScrollVertically(): Boolean = false
}

I experienced this crash even though I had the RecyclerView.LayoutManager properly set. I had to move the RecyclerView initialization code into the onViewCreated(...) callback to fix this issue.

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

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    mLayoutManager = new LinearLayoutManager(getActivity());
    mLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);

    mRecyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
    mRecyclerView.setItemAnimator(new DefaultItemAnimator());
    mRecyclerView.setLayoutManager(mLayoutManager);

    mAdapter = new ListingAdapter(mListing);
    mRecyclerView.setAdapter(mAdapter);
}

This did the trick for me. It captures all the stdout output from the subprocess(For python 3.8):

from subprocess import check_output, STDOUT
cmd = "Your Command goes here"
try:
    cmd_stdout = check_output(cmd, stderr=STDOUT, shell=True).decode()
except Exception as e:
    print(e.output.decode()) # print out the stdout messages up to the exception
    print(e) # To print out the exception message

I've been using ClockPick.

df.shape, where df is your DataFrame.

Actually what you are searching is: Optional.map. Your code would then look like:

object.map(o -> "result" /* or your function */)
      .orElseThrow(MyCustomException::new);

I would rather omit passing the Optional if you can. In the end you gain nothing using an Optional here. A slightly other variant:

public String getString(Object yourObject) {
  if (Objects.isNull(yourObject)) { // or use requireNonNull instead if NullPointerException suffices
     throw new MyCustomException();
  }
  String result = ...
  // your string mapping function
  return result;
}

If you already have the Optional-object due to another call, I would still recommend you to use the map-method, instead of isPresent, etc. for the single reason, that I find it more readable (clearly a subjective decision ;-)).

Sleep() causes the currently executing thread to sleep (temporarily cease execution).

Yield() causes the currently executing thread object to temporarily pause and allow other threads to execute.

Read [this] (Link Removed) for a good explanation of the topic.

$ThatTime ="14:08:10";
if (time() >= strtotime($ThatTime)) {
  echo "ok";
}

A solution using DateTime (that also regards the timezone).

$dateTime = new DateTime($ThatTime);
if ($dateTime->diff(new DateTime)->format('%R') == '+') {
  echo "OK";
}

Wow, you have a huge misunderstanding how asp.net works.

This line of code

System.Diagnostics.Process.Start("help/AdminTutorial.html");

Will not redirect a admin user to a new site, but start a new process on the server (usually a browser, IE) and load the site. That is for sure not what you want.

A very easy solution would be to change the href attribute of the link in you page_load method.

Your aspx code:

<a href="#" runat="server" id="myLink">Tutorial</a>

Your codebehind / cs code of page_load:

...
if (userinfo.user == "Admin")
{
  myLink.Attributes["href"] = "help/AdminTutorial.html";
}
else 
{
  myLink.Attributes["href"] = "help/otherSite.html";
}
...

Don't forget to check the Admin rights again on "AdminTutorial.html" to "prevent" hacking.

It is not necessary to have two routes.

Simply add (/*)? at the end of your path string.

For example, app.get('/hello/world(/*)?' /* ... */)

Here is a fully working example, feel free to copy and paste this into a .js file to run with node, and play with it in a browser (or curl):

const app = require('express')()

// will be able to match all of the following
const test1 = 'http://localhost:3000/hello/world'
const test2 = 'http://localhost:3000/hello/world/'
const test3 = 'http://localhost:3000/hello/world/with/more/stuff'

// but fail at this one
const failTest = 'http://localhost:3000/foo/world'

app.get('/hello/world(/*)?', (req, res) => res.send(`
    This will match at example endpoints: <br><br>
    <pre><a href="${test1}">${test1}</a></pre>
    <pre><a href="${test2}">${test2}</a></pre>
    <pre><a href="${test3}">${test3}</a></pre>

    <br><br> Will NOT match at: <pre><a href="${failTest}">${failTest}</a></pre>
`))

app.listen(3000, () => console.log('Check this out in a browser at http://localhost:3000/hello/world!'))

In addition to others' proposals, there is another option to handle that issue.

If your application should behave the same in case of lack of "href" attribute, as in case of it being empty, just replace this:

var theHref = $(obj.mainImg_select).attr('href');

with this:

var theHref = $(obj.mainImg_select).attr('href') || '';

which will treat empty string ('') as the default, if the attribute has not been found.

But it really depends, on how you want to handle undefined "href" attribute. This answer assumes you will want to handle it as if it was empty string.

Easy to read/type.

  table = new char[][] {
      "0123456789".toCharArray()
    , "abcdefghij".toCharArray()
  };

In the example you give, you're perfectly right, you have to set the title attribute.

If the aria-label is one tool used by assistive technologies (like screen readers), it is not natively supported on browsers and has no effect on them. It won't be of any help to most of the people targetted by the WCAG (except screen reader users), for instance a person with intellectal disabilities.

The "X" is not sufficient enough to give information to the action led by the button (think about someone with no computer knowledge). It might mean "close", "delete", "cancel", "reduce", a strange cross, a doodle, nothing.

Despite the fact that the W3C seems to promote the aria-label rather that the title attribute here: http://www.w3.org/TR/2014/NOTE-WCAG20-TECHS-20140916/ARIA14 in a similar example, you can see that the technology support does not include standard browsers : http://www.w3.org/WAI/WCAG20/Techniques/ua-notes/aria#ARIA14

In fact aria-label, in this exact situation might be used to give more context to an action:

For instance, blind people do not perceive popups like those of us with good vision, it's like a change of context. "Back to the page" will be a more convenient alternative for a screen reader, when "Close" is more significant for someone with no screen reader.

  <button
      aria-label="Back to the page"
      title="Close" onclick="myDialog.close()">X</button>

can also Use parameterized each with index and the element.

$('#selectIntegrationConf').find('option').each(function(index,element){
 console.log(index);
 console.log(element.value);
 console.log(element.text);
 });

// this will also work

$('#selectIntegrationConf option').each(function(index,element){
 console.log(index);
 console.log(element.value);
 console.log(element.text);
 });

You can define a function type in interface in various ways,

1. general way:

export interface IParam {
  title: string;
  callback(arg1: number, arg2: number): number;
}

2. If you would like to use property syntax then,

export interface IParam {
  title: string;
  callback: (arg1: number, arg2: number) => number;
}

3. If you declare the function type first then,

type MyFnType = (arg1: number, arg2: number) => number;

export interface IParam {
  title: string;
  callback: MyFnType;
}

Using is very straight forward,

function callingFn(paramInfo: IParam):number {
    let needToCall = true;
    let result = 0;
   if(needToCall){
     result = paramInfo.callback(1,2);
    }

    return result;
}

4. You can declare a function type literal also , which mean a function can accept another function as it's parameter. parameterize function can be called as callback also.

export interface IParam{
  title: string;
  callback(lateCallFn?:
             (arg1:number,arg2:number)=>number):number;

}

I got this error Unexpected identifier because of a missing semi-colon ; at the end of a line. Anyone wandering here for other than above-mentioned solutions, This might also be the cause of this error.

EDIT: Warning: Please, read the answer posted by Evan Carroll. It seems that this solution is not safe and not recommended.

This worked for me in the standard Ubuntu 14.04 64 bits installation.

I followed the instructions, with small modifications, that I found in http://suite.opengeo.org/4.1/dataadmin/pgGettingStarted/firstconnect.html

1. Install postgreSQL (if not already in your machine):

sudo apt-get install postgresql

2. Run psql using the postgres user

sudo –u postgres psql postgres

3. Set a new password for the postgres user:

\password postgres

4. Exit psql

\q

5. Edit /etc/postgresql/9.3/main/pg_hba.conf and change:

#Database administrative login by Unix domain socket local all postgres peer

To:

#Database administrative login by Unix domain socket local all postgres md5

6. Restart postgreSQL:

sudo service postgresql restart

7. Create a new database

sudo –u postgres createdb mytestdb

8. Run psql with the postgres user again:

psql –U postgres –W

9. List the existing databases (your new database should be there now):

\l

You can use WMIC or SCHTASKS (which means no third party software is needed):

1) SCHTASKS:

SCHTASKS /s remote_machine /U username /P password /create /tn "On demand demo" /tr "C:\some.bat" /sc ONCE /sd 01/01/1910 /st 00:00
SCHTASKS /s remote_machine /U username /P password /run /TN "On demand demo" 

2) WMIC (wmic will return the pid of the started process)

WMIC /NODE:"remote_machine" /user user /password password process call create "c:\some.bat","c:\exec_dir"

You don't even have to set a specific width for the cells, table-layout: fixed suffices to spread the cells evenly.

ul {_x000D_
    width: 100%;_x000D_
    display: table;_x000D_
    table-layout: fixed;_x000D_
    border-collapse: collapse;_x000D_
}_x000D_
li {_x000D_
    display: table-cell;_x000D_
    text-align: center;_x000D_
    border: 1px solid hotpink;_x000D_
    vertical-align: middle;_x000D_
    word-wrap: break-word;_x000D_
}

<ul>_x000D_
  <li>foo<br>foo</li>_x000D_
  <li>barbarbarbarbar</li>_x000D_
  <li>baz</li>_x000D_
</ul>

Note that for table-layout to work the table styled element must have a width set (100% in my example).

Well, to calculate the average of an array, you can consider using for loop instead of while loop.

So as per your question let me assume an array as arrNumbers ( here i'm considering the same array elements as in your question )

int arrNumbers[] = new int[]{1, 3, 2, 5, 8};
int sum = 0;

for(int a = 0; a < arrNumbers.length; a++)
{
   sum = sum + arrNumbers[a];
}

double average = sum / arrNumbers.length;

System.out.println("Average is: " + average);

You can use scanner class as well. It's left to you.

After the configure step you probably have a makefile. Inside this makefile look for CFLAGS (or similar). puf -fPIC at the end and run make again. In other words -fPIC is a compiler option that has to be passed to the compiler somewhere.

The most robust mechanism for listing all resources in the classpath is currently to use this pattern with ClassGraph, because it handles the widest possible array of classpath specification mechanisms, including the new JPMS module system. (I am the author of ClassGraph.)

List<String> resourceNames;
try (ScanResult scanResult = new ClassGraph().whitelistPaths("x/y/z").scan()) {
    resourceNames = scanResult.getAllResources().getNames();
}

I found this blog post very helpful. It saved my day. http://www.techsirius.com/2014/05/simple-geo-tracking-system.html

Basically you need to install the IP database table and then do mysql query for the IP for location.

<?php
include 'config.php';
mysql_connect(DB_HOST, DB_USER, DB_PASSWORD) OR die(mysql_error());
mysql_select_db(DB_NAME) OR die(mysql_error());
$ip =  $_SERVER['REMOTE_ADDR'];
$long = sprintf('%u', ip2long($ip));
$sql = "SELECT * FROM `geo_ips` WHERE '$long' BETWEEN `ip_start` AND `ip_end`";
$result = mysql_query($sql) OR die(mysql_error());
$ip_detail = mysql_fetch_assoc($result);
if($ip_detail){
    echo $ip_detail['country']."', '".$ip_detail['state']."', '".$ip_detail['city'];
}
else{
    //Something wrong with IP
}

I had the same problem for a while now. Until I searched through the Android Studio site and bumped with the introduction. Then I found how to activate (I think) the autocomplete feature. It says press Control+Space and when I did, it worked.

You can also use chmod 777 *

This will give permissions to all files currently in the folder and files added in the future without giving permissions to the directory itself.

NOTE: This should be done in the folder where the files are located. For me it was an images that had an issue so I went to my images folder and did this.

I just install stylus by default under my home dir, so I just use npm uninstall stylus to detach it, or you can try npm rm <package_name> out.

You can do it programmatically by reading the java system properties

@Test
public void javaVersion() {
    System.out.println(System.getProperty("java.version"));
    System.out.println(System.getProperty("java.runtime.version"));
    System.out.println(System.getProperty("java.home"));
    System.out.println(System.getProperty("java.vendor"));
    System.out.println(System.getProperty("java.vendor.url"));
    System.out.println(System.getProperty("java.class.path"));
}

This will output somthing like

1.7.0_17
1.7.0_17-b02
C:\workspaces\Oracle\jdk1.7\jre
Oracle Corporation
http://java.oracle.com/
C:\workspaces\Misc\Miscellaneous\bin; ...

The first line shows the version number. You can parse it an see whether it fits your minimun required java version or not. You can find a description for the naming convention here and more infos here.

What's you've got there should be fine to work, but there is no actual "Is Mobile/Tablet" media query so you're always going to be stuck.

There are media queries for common breakpoints , but with the ever changing range of devices they're not guaranteed to work moving forwards.

The idea is that your site maintains the same brand across all sizes, so you should want the styles to cascade across the breakpoints and only update the widths and positioning to best suit that viewport.

To further the answer above, using Modernizr with a no-touch test will allow you to target touch devices which are most likely tablets and smart phones, however with the new releases of touch based screens that is not as good an option as it once was.

I would use regular expression matching to sum over variables with certain pattern names. For example:

df <- df %>% mutate(sum1 = rowSums(.[grep("x[3-5]", names(.))], na.rm = TRUE),
                    sum_all = rowSums(.[grep("x", names(.))], na.rm = TRUE))

This way you can create more than one variable as a sum of certain group of variables of your data frame.

Use CSS. It's easier and faster than javascript.

overflow-x: hidden;
overflow-y: scroll;

Using the RESTORE DATABASE command most likely. bak is a common extension used for a database backup file. You'll find documentation for this command on MSDN.

Already if you are using itextsharp dll, no need to add third party dll's(plugin), I think you are using htmlworker instead of it use xmlworker you can easily convert your html to pdf.

As of Spring 3.2, this is no longer an issue. Spring now supports Autowiring of the results of generic factory methods. See the section entitled "Generic Factory Methods" in this blog post: http://spring.io/blog/2012/11/07/spring-framework-3-2-rc1-new-testing-features/.

The key point is:

In Spring 3.2, generic return types for factory methods are now properly inferred, and autowiring by type for mocks should work as expected. As a result, custom work-arounds such as a MockitoFactoryBean, EasyMockFactoryBean, or Springockito are likely no longer necessary.

Which means this should work out of the box:

<bean id="dao" class="org.mockito.Mockito" factory-method="mock">
    <constructor-arg value="com.package.Dao" />
</bean>

For those who may be confused by the accepted answer, as I was, you also need to have the ruby headers installed [ruby-devel].

The article that saved my hide is here.

And this is the revised solution (note that I'm on Fedora 13):

yum -y install gcc mysql-devel ruby-devel rubygems
gem install -y mysql -- --with-mysql-config=/usr/bin/mysql_config

For Debian, and other distributions using Debian style packaging the ruby development headers are installed by:

sudo apt-get install ruby-dev

For Ubuntu the ruby development headers are installed by:

sudo apt-get install ruby-all-dev

If you are using a earlier version of ruby (such as 2.2), then you will need to run:

sudo apt-get install ruby2.2-dev

(where 2.2 is your desired Ruby version)

Let me expand a bit on a VonC's very comprehensive answer:

First, if I remember it correctly, the fact that Git by default doesn't create merge commits in the fast-forward case has come from considering single-branch "equal repositories", where mutual pull is used to sync those two repositories (a workflow you can find as first example in most user's documentation, including "The Git User's Manual" and "Version Control by Example"). In this case you don't use pull to merge fully realized branch, you use it to keep up with other work. You don't want to have ephemeral and unimportant fact when you happen to do a sync saved and stored in repository, saved for the future.

Note that usefulness of feature branches and of having multiple branches in single repository came only later, with more widespread usage of VCS with good merging support, and with trying various merge-based workflows. That is why for example Mercurial originally supported only one branch per repository (plus anonymous tips for tracking remote branches), as seen in older revisions of "Mercurial: The Definitive Guide".

Second, when following best practices of using feature branches, namely that feature branches should all start from stable version (usually from last release), to be able to cherry-pick and select which features to include by selecting which feature branches to merge, you are usually not in fast-forward situation... which makes this issue moot. You need to worry about creating a true merge and not fast-forward when merging a very first branch (assuming that you don't put single-commit changes directly on 'master'); all other later merges are of course in non fast-forward situation.

NPX:

From https://www.futurehosting.com/blog/npx-makes-life-easier-for-node-developers-plus-node-vulnerability-news/:

Web developers can have dozens of projects on their development machines, and each project has its own particular set of npm-installed dependencies. A few years back, the usual advice for dealing with CLI applications like Grunt or Gulp was to install them locally in each project and also globally so they could easily be run from the command line.

But installing globally caused as many problems as it solved. Projects may depend on different versions of command line tools, and polluting the operating system with lots of development-specific CLI tools isn’t great either. Today, most developers prefer to install tools locally and leave it at that.

Local versions of tools allow developers to pull projects from GitHub without worrying about incompatibilities with globally installed versions of tools. NPM can just install local versions and you’re good to go. But project specific installations aren’t without their problems: how do you run the right version of the tool without specifying its exact location in the project or playing around with aliases?

That’s the problem npx solves. A new tool included in NPM 5.2, npx is a small utility that’s smart enough to run the right application when it’s called from within a project.

If you wanted to run the project-local version of mocha, for example, you can run npx mocha inside the project and it will do what you expect.

A useful side benefit of npx is that it will automatically install npm packages that aren’t already installed. So, as the tool’s creator Kat Marchán points out, you can run npx benny-hill without having to deal with Benny Hill polluting the global environment.

If you want to take npx for a spin, update to the most recent version of npm.

Here's a straightforward and generic example.

The filter:

sampleApp.filter('unique', function() {

  // Take in the collection and which field
  //   should be unique
  // We assume an array of objects here
  // NOTE: We are skipping any object which
  //   contains a duplicated value for that
  //   particular key.  Make sure this is what
  //   you want!
  return function (arr, targetField) {

    var values = [],
        i, 
        unique,
        l = arr.length, 
        results = [],
        obj;

    // Iterate over all objects in the array
    // and collect all unique values
    for( i = 0; i < arr.length; i++ ) {

      obj = arr[i];

      // check for uniqueness
      unique = true;
      for( v = 0; v < values.length; v++ ){
        if( obj[targetField] == values[v] ){
          unique = false;
        }
      }

      // If this is indeed unique, add its
      //   value to our values and push
      //   it onto the returned array
      if( unique ){
        values.push( obj[targetField] );
        results.push( obj );
      }

    }
    return results;
  };
})

The markup:

<div ng-repeat = "item in items | unique:'name'">
  {{ item.name }}
</div>
<script src="your/filters.js"></script>

I managed to find the required function in lodash, a utility library similar to underscore.

http://lodash.com/docs#mapValues

_.mapValues(object, [callback=identity], [thisArg])

Creates an object with the same keys as object and values generated by running each own enumerable property of object through the callback. The callback is bound to thisArg and invoked with three arguments; (value, key, object).

If you're using Bash you could also use one of the following commands:

printf '%(%Y%m%d%H%M%S)T'       # prints the current time
printf '%(%Y%m%d%H%M%S)T' -1    # same as above
printf '%(%Y%m%d%H%M%S)T' -2    # prints the time the shell was invoked

You can use the Option -v varname to store the result in $varname instead of printing it to stdout:

printf -v varname '%(%Y%m%d%H%M%S)T'

While the date command will always be executed in a subshell (i.e. in a separate process) printf is a builtin command and will therefore be faster.

when you need in a timestamp in seconds, you can use the following:

var timestamp = (int)(DateTime.Now.ToUniversalTime() - new DateTime(1970, 1, 1)).TotalSeconds;

Use this:

static int RandomNumber(int min, int max)
{
    Random random = new Random(); return random.Next(min, max);

}

This is example for you to modify and use in your application.

Here's an alternative solution using requests:

import requests
wjdata = requests.get('url').json()
print wjdata['data']['current_condition'][0]['temp_C']

I'm putting this in a new answer because no linebreaks / codeblocks in comments. I assume you want those nans to turn into a blank string? I couldn't find a nice way to do this, only do the ugly method:

s = pd.Series([1001.,1002.,None])
a = s.loc[s.isnull()].fillna('')
b = s.loc[s.notnull()].astype(int).astype(str)
result = pd.concat([a,b])

Including "string.h" makes things easier. An easier way to tackle your problem is:

#include <string.h>
    char* createStr(){
    static char str[20] = "my";
    return str;
}
int main(){
    char a[20];
    strcpy(a,createStr()); //this will copy the returned value of createStr() into a[]
    printf("%s",a);
    return 0;
}

As @Peter Cullen answer mention, your script will meet browser timeout first. So its good idea to provide some log output, then flush(), but connection have buffer and you'll not see anything unless much output provided. Here are code snippet what helps provide reliable log:

set_time_limit(0);
...
print "log message";
print "<!--"; print str_repeat (' ', 4000); print "-->"; flush();
print "log message";
print "<!--"; print str_repeat (' ', 4000); print "-->"; flush();

If you are writing code in Swift it would look as an example like this

func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String?
{
    switch section
    {
        case 0:
            return "Apple Devices"
        case 1:
            return "Samsung Devices"
        default:
            return "Other Devices"
    }
}

Similar to what you have, you could do something like

if (some_variable === undefined || some_variable === null) { do stuff }

Not so hard:

#include <thread>

void Test::runMultiThread()
{
    std::thread t1(&Test::calculate, this,  0, 10);
    std::thread t2(&Test::calculate, this, 11, 20);
    t1.join();
    t2.join();
}

If the result of the computation is still needed, use a future instead:

#include <future>

void Test::runMultiThread()
{
     auto f1 = std::async(&Test::calculate, this,  0, 10);
     auto f2 = std::async(&Test::calculate, this, 11, 20);

     auto res1 = f1.get();
     auto res2 = f2.get();
}

Here is the one-liner version getting the client's IP address:

$ip = @$_SERVER['HTTP_CLIENT_IP'] ?: @$_SERVER['HTTP_X_FORWARDED_FOR'] ?: @$_SERVER['REMOTE_ADDR'];

Notes:

• By using @, it suppresses the PHP notices.

• Value from HTTP_X_FORWARDED_FOR may consist multiple addresses separated by comma, so if you prefer to get the first one, you can use the following method:

  current(explode(',', @$_SERVER['HTTP_X_FORWARDED_FOR']))
