"await is only valid in async function"

But why? 'await' explicitly turns an async call into a synchronous call, and therefore the caller cannot be async (or asyncable) - at least, not because of the call being made at 'await'.

Escaping parameters like that is usually source of frustration and feels a lot like a time wasted. I see you're on v2 so I would suggest using a technique that Joel "Jaykul" Bennet blogged about a while ago.

Long story short: you just wrap your string with @' ... '@ :

Start-Process \\server\toto.exe @'
-batch=B -param="sort1;parmtxt='Security ID=1234'"
'@

(Mind that I assumed which quotes are needed, and which things you were attempting to escape.) If you want to work with the output, you may want to add the -NoNewWindow switch.

BTW: this was so important issue that since v3 you can use --% to stop the PowerShell parser from doing anything with your parameters:

\\server\toto.exe --% -batch=b -param="sort1;paramtxt='Security ID=1234'"

... should work fine there (with the same assumption).

This is FAQ 7.10. Others have shown how to apply this to a single column in a data frame, or to multiple columns in a data frame. But this is really treating the symptom, not curing the cause.

A better approach is to use the colClasses argument to read.table and related functions to tell R that the column should be numeric so that it never creates a factor and creates numeric. This will put in NA for any values that do not convert to numeric.

Another better option is to figure out why R does not recognize the column as numeric (usually a non numeric character somewhere in that column) and fix the original data so that it is read in properly without needing to create NAs.

Best is a combination of the last 2, make sure the data is correct before reading it in and specify colClasses so R does not need to guess (this can speed up reading as well).

I realize this is an old question but I found this on mozilla.org and think it applies.

A button can be of three types: submit, reset, or button. A click on a submit button sends the form's data to the web page defined by the action attribute of the element.

A click on a reset button resets all the form widgets to their default value immediately. From a UX point of view, this is considered bad practice.

A click on a button button does... nothing! That sounds silly, but it's amazingly useful to build custom buttons with JavaScript.

https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Forms/My_first_HTML_form#And_a_<button>_to_finish

To easily understand the problem, imagine we wrote this code:

static void Main(string[] args)
{
    string[] test = new string[3];
    test[0]= "hello1";
    test[1]= "hello2";
    test[2]= "hello3";

    for (int i = 0; i <= 3; i++)
    {
        Console.WriteLine(test[i].ToString());
    }
}

Result will be:

hello1
hello2
hello3

Unhandled Exception: System.IndexOutOfRangeException: Index was outside the bounds of the array.

Size of array is 3 (indices 0, 1 and 2), but the for-loop loops 4 times (0, 1, 2 and 3).
So when it tries to access outside the bounds with (3) it throws the exception.

Volatile means other threads can edit that particular variable. So the compiler allows access to them.

http://www.javamex.com/tutorials/synchronization_volatile.shtml

Transient means that when you serialize an object, it will return its default value on de-serialization

From the pthread function prototype:

int pthread_create(pthread_t *thread, const pthread_attr_t *attr,
    void *(*start_routine)(void*), void *arg);

The function passed to pthread_create must have a prototype of

void* name(void *arg)

Yet another answer, since the person said "I don't know how many times my function will be called", you could use the vector insert method like so to append arrays of values to the end of the vector:

vector<int> x;

void AddValues(int* values, size_t size)
{
   x.insert(x.end(), values, values+size);
}

I like this way because the implementation of the vector should be able to optimize for the best way to insert the values based on the iterator type and the type itself. You are somewhat replying on the implementation of stl.

If you need to guarantee the fastest speed and you know your type is a POD type then I would recommend the resize method in Thomas's answer:

vector<int> x;

void AddValues(int* values, size_t size)
{
   size_t old_size(x.size());
   x.resize(old_size + size, 0);
   memcpy(&x[old_size], values, size * sizeof(int));
}

I did this by installing Cygwin64 from this link https://www.cygwin.com/ Then - View Full, Search gcc and scroll down to find pkg-config. Click on icon to select latest version. This worked for me well.

You have to specify the name of the custom view and its related model in Controller Action method.

public ActionResult About()
{            
   return View("NameOfViewYouWantToReturn",Model); 
}

It is used to find the how many rows contain data in a worksheet that contains data in the column "A". The full usage is

 lastRowIndex = ws.Cells(ws.Rows.Count, "A").End(xlUp).row

Where ws is a Worksheet object. In the questions example it was implied that the statement was inside a With block

With ws
    lastRowIndex = .Cells(.Rows.Count, "A").End(xlUp).row
End With

1. ws.Rows.Count returns the total count of rows in the worksheet (1048576 in Excel 2010).
2. .Cells(.Rows.Count, "A") returns the bottom most cell in column "A" in the worksheet

Then there is the End method. The documentation is ambiguous as to what it does.

Returns a Range object that represents the cell at the end of the region that contains the source range

Particularly it doesn't define what a "region" is. My understanding is a region is a contiguous range of non-empty cells. So the expected usage is to start from a cell in a region and find the last cell in that region in that direction from the original cell. However there are multiple exceptions for when you don't use it like that:

• If the range is multiple cells, it will use the region of rng.cells(1,1).
• If the range isn't in a region, or the range is already at the end of the region, then it will travel along the direction until it enters a region and return the first encountered cell in that region.
• If it encounters the edge of the worksheet it will return the cell on the edge of that worksheet.

So Range.End is not a trivial function.

4. .row returns the row index of that cell.

for(int i=1;i<=9;i++) {
    p3.add(new JButton(""+i) {{
        // initialize the JButton directly
        setBackground(Color.BLACK);
        setForeground(Color.GRAY);
    }});
}

These regexes are equivalent (for matching purposes):

• /^(7|8|9)\d{9}$/
• /^[789]\d{9}$/
• /^[7-9]\d{9}$/

The explanation:

• (a|b|c) is a regex "OR" and means "a or b or c", although the presence of brackets, necessary for the OR, also captures the digit. To be strictly equivalent, you would code (?:7|8|9) to make it a non capturing group.

• [abc] is a "character class" that means "any character from a,b or c" (a character class may use ranges, e.g. [a-d] = [abcd])

The reason these regexes are similar is that a character class is a shorthand for an "or" (but only for single characters). In an alternation, you can also do something like (abc|def) which does not translate to a character class.

You will not be able to do that. You can download apps again to the same userid account on different devices, but you cannot transfer those licenses to other userids.

There is no way to do this programatically - I don't think you can do that practically (except for trying to call customer support at the Play Store).

tmp.innerText is undefined. You should use tmp.innerHTML

function strip(html) 
    {  
        var tmp = document.createElement("DIV"); 
        tmp.innerHTML = html; 
        var urlRegex =/(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;   
        return tmp.innerHTML .replace(urlRegex, function(url) {     
        return '\n' + url 
    })

In the below example, I have stored the Makefile folder path to LOCAL_PKG_DIR and then use LOCAL_PKG_DIR variable in targets.

Makefile:

LOCAL_PKG_DIR := $(shell eval pwd)

.PHONY: print
print:
    @echo $(LOCAL_PKG_DIR)

Terminal output:

$ make print

The most efficient and safest way to determine if a row exists is by using a FOR-LOOP... You won't even have a difficult time if you are looking to insert a row or do something based on the row NOT being there but, this will certainly help you if you need to determine if a row exists. See example code below for the ins and outs...

If you are only interested in knowing that 1 record exists in your potential multiple return set, than you can exit your loop after it hits it for the first time.

The loop will not be entered into at all if no record exists. You will not get any complaints from Oracle or such if the row does not exist but you are bound to find out if it does regardless. Its what I use 90% of the time (of course dependent on my needs)...

EXAMPLE:

DECLARE

v_exist varchar2(20);

BEGIN
   FOR rec IN
   (SELECT LOT, COMPONENT 
   FROM TABLE
   WHERE REF_DES = (SELECT REF_DES FROM TABLE2 WHERE ORDER = '1234') 
   AND ORDER = '1234')
  LOOP

      v_exist := "IT_EXISTS"

   INSERT INTO EAT_SOME_SOUP_TABLE (LOT, COMPONENT) 
   VALUES (rec.LOT, rec.COMPONENT);**

   --Since I don't want to do this for more than one iteration (just in case there may have been more than one record returned, I will EXIT;

   EXIT;
   END LOOP;



IF v_exist  IS NULL

    THEN

            --do this

END IF;

END;

--This is outside the loop right here The IF-CHECK just above will run regardless, but then you will know if your variable is null or not right!?. If there was NO records returned, it will skip the loop and just go here to the code you would have next... If (in our case above), 4 records were returned, I would exit after the first iteration due to my EXIT;... If that wasn't there, the 4 records would iterate through and do an insert on all of them. Or at least try too.

By the way, I'm not saying this is the only way you should consider doing this... You can

SELECT COUNT(*) INTO v_counter WHERE ******* etc...

Then check it like

if v_counter > 0
      THEN
         --code goes here
   END IF;

There are more ways... Just determine it when your need arises. Keep performance in mind, and safety.

I know this is an old question.

Here's another option - attending to different platform requirements - Source

<link rel='shortcut icon' type='image/vnd.microsoft.icon' href='/favicon.ico'> <!-- IE -->
<link rel='apple-touch-icon' type='image/png' href='/icon.57.png'> <!-- iPhone -->
<link rel='apple-touch-icon' type='image/png' sizes='72x72' href='/icon.72.png'> <!-- iPad -->

<link rel='icon' type='image/png' href='/icon.114.png'> <!-- Opera Speed Dial, at least 144×114 px -->

This is the broadest approach I have found so far.

Ultimately the decision depends on your own needs. Ask yourself, who is your target audience?

UPDATE May 27, 2018: As expected, time goes by and things change. But there's good news too. I found a tool called Real Favicon Generator that generates all the required lines for the icon to work on all modern browsers and platforms. It doesn't handle backwards compatibility though.

The reasonable way how to launch apps from HTML is through url schemes. So you can launch email via mailto: links and irc through irc: links. Individual apps can implement these schemes, but I'm not sure WinMerge does this.

The + operator returns the numeric representation of the object. So in your particular case, it would appear to be predicating the if on whether or not d is a non-zero number.

Reference here. And, as pointed out in comments, here.

I was getting the same error on a restored database when I tried to insert a new record using the EntityFramework. It turned out that the Indentity/Seed was screwing things up.

Using a reseed command fixed it.

I came up with a couple regular expressions for PHP that will convert urls in text to anchor tags. (First it converts all www. urls to http:// then converts all urls with https?:// to a href=... html links

$string = preg_replace('/(https?:\/\/)([!#$&-;=?\-\[\]_a-z~%]+)/sim', '<a href="$1$2">$2</a>', preg_replace('/(\s)((www\.)([!#$&-;=?\-\[\]_a-z~%]+))/sim', '$1http://$2', $string) );

I've uploaded a Nuget Package that can make it so simple, you can have it from here ActionScheduler

It supports .NET Standard 2.0

And here how to start using it

using ActionScheduler;

var jobScheduler = new JobScheduler(TimeSpan.FromMinutes(8), new Action(() => {
  //What you want to execute
}));

jobScheduler.Start(); // To Start up the Scheduler

jobScheduler.Stop(); // To Stop Scheduler from Running.

This is the best way:

Just be sure to backup the copies of the files first.

EDIT

The edit by Neon got unfortunately rejected during review.
See Neons post below, it might contain useful information!

E.g. to remove all *.gz files accidentally committed into git repository:

$ du -sh .git ==> e.g. 100M
$ git filter-branch --index-filter 'git rm --cached --ignore-unmatch *.gz' HEAD
$ git push origin master --force
$ rm -rf .git/refs/original/
$ git reflog expire --expire=now --all
$ git gc --prune=now
$ git gc --aggressive --prune=now

That still didn't work for me? (I am currently at git version 1.7.6.1)

$ du -sh .git ==> e.g. 100M

Not sure why, since I only had ONE master branch. Anyways, I finally got my git repo truely cleaned up by pushing into a new empty and bare git repository, e.g.

$ git init --bare /path/to/newcleanrepo.git
$ git push /path/to/newcleanrepo.git master
$ du -sh /path/to/newcleanrepo.git ==> e.g. 5M 

(yes!)

Then I clone that to a new directory and moved over it's .git folder into this one. e.g.

$ mv .git ../large_dot_git
$ git clone /path/to/newcleanrepo.git ../tmpdir
$ mv ../tmpdir/.git .
$ du -sh .git ==> e.g. 5M 

(yeah! finally cleaned up!)

After verifying that all is well, then you can delete the ../large_dot_git and ../tmpdir directories (maybe in a couple weeks or month from now, just in case...)

You have to set the default option by passing a third argument.

{{ Form::select('myselect', [1, 2], 2, ['id' => 'myselect']) }}

You can read the documentation here.

git config user.email "insert github email here"
git config user.name "insert github real name here"

This worked great for me.

Maven will not run your tests if the project has <packaging>pom</packaging>

You need to set the packaging to jar (or some other java artefact type) for the tests to run: <packaging>jar</packaging>

EDIT: This is no longer the right way to use refs with Typescript. Look at Jeff Bowen's answer and upvote it to increase its visibility.

Found the answer to the problem. Use refs as below inside the class.

refs: {
    [key: string]: (Element);
    stepInput: (HTMLInputElement);
}

Thanks @basarat for pointing in the right direction.

Yes. It is possible :D

SELECT  SUM(totalHours) totalHours
FROM
        ( 
            select sum(hours) totalHours from resource
            UNION ALL
            select sum(hours) totalHours from projects-time
        ) s

As a sidenote, the tablename projects-time must be delimited to avoid syntax error. Delimiter symbols vary on RDBMS you are using.

The problem was with the QuickText plugin. After removing it, indent worked as normal.

How about this:

import sys
import subprocess

theproc = subprocess.Popen("myscript.py", shell = True)
theproc.communicate()                   # ^^^^^^^^^^^^

This tells subprocess to use the OS shell to open your script, and works on anything that you can just run in cmd.exe.

Additionally, this will search the PATH for "myscript.py" - which could be desirable.

Don't use SSL on port 465, it's been deprecated since 1998 and is only used by Microsoft products that didn't get the memo; use TLS on port 587 instead: So, the code below should work very well for you.

mail->IsSMTP(); // telling the class to use SMTP
$mail->Host       = "smtp.gmail.com"; // SMTP server

$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->SMTPSecure = "tls";                 // sets the prefix to the servier
$mail->Host       = "smtp.gmail.com";      // sets GMAIL as the SMTP server
$mail->Port       = 587;                   // set the SMTP port for the 

I had the same issue. I installed gitx instead.

You can install gitx from here.

http://rowanj.github.io/gitx/

Download the package and install it. After that open the gitk from spotlight search, goto the top left corner. Click on GitX and enable the terminal usage.

Goto your repo and simply type:

$ gitx --all

It will open the Gui.

User manual: http://gitx.frim.nl/user_manual.html

As mentioned by others: git doesn't track folders, only files.

You can ensure a folder exists with these commands (or equivalent logic):

echo "*" > keepthisfolder/.gitignore
git add --force keepthisfolder/.gitignore
git commit -m "adding git ignore file to keepthisfolder"

The existence of the file will mean anyone checking out the repository will have the folder.

The contents of the gitignore file will mean anything in it are ignored

You do not need to not-ignore the .gitignore file itself. It is a rule which would serve no purpose at all once committed.

OR

if you prefer to keep all your ignore definitions in the same place, you can create .gitignore in the root of your project with contents like so:

*.tmp # example, ignore all .tmp files in any folder
path/to/keepthisfolder
path/to/keepthatfolder

and to ensure the folders exist

touch path/to/keepthisfolder/anything
git add --force path/to/keepthisfolder/anything
git commit -m "ensure keepthisfolder exists when checked out"

"anything" can literally be anything. Common used names are .gitignore, .gitkeep, empty.

A more fancy way to do it: :)

var options = window.location.search.slice(1)
                      .split('&')
                      .reduce(function _reduce (/*Object*/ a, /*String*/ b) {
                        b = b.split('=');
                        a[b[0]] = decodeURIComponent(b[1]);
                        return a;
                      }, {});

The ?type=daily argument (ending up in the $_GET array) is only valid for web-accessed pages.

You'll need to call it like php myfile.php daily and retrieve that argument from the $argv array (which would be $argv[1], since $argv[0] would be myfile.php).

If the page is used as a webpage as well, there are two options you could consider. Either accessing it with a shell script and Wget, and call that from cron:

#!/bin/sh
wget http://location.to/myfile.php?type=daily

Or check in the PHP file whether it's called from the command line or not:

if (defined('STDIN')) {
  $type = $argv[1];
} else {
  $type = $_GET['type'];
}

(Note: You'll probably need/want to check if $argv actually contains enough variables and such)

grep's -A 1 option will give you one line after; -B 1 will give you one line before; and -C 1 combines both to give you one line both before and after, -1 does the same.

You can simply install an Android studio Martial icons plugin its name is please check plugin URL Material Design Icon Generator and check this GIF for more details:

We use HSQLDB in production as a "no-configuration" option for our application. It allows people to trial without the hassle of setting up a real database.

However we do not support it for normal use. The reasons are several:

1. Slows down proportionally to the size of the data.
2. Difficult to access outside of our app (e.g. for custom reports).
3. Transactions / disk-sync is difficult to get right, so it's easy to lose data.

For at least (2) and (3), there are ways around it but it's difficult; it's much easier to e.g. install MySQL.

I understand you want to create stuff dynamically. That does not mean you have to actually construct DOM elements to do it. You can just make use of html to achieve what you want .

Look at the code below :

HTML:

<table border="0" cellpadding="0" width="100%" id='providersFormElementsTable'></table>

JS :

createFormElement("Nickname","nickname")

function createFormElement(labelText, id) {

$("#providersFormElementsTable").html("<tr><td>Nickname</td><td><input type='text' id='"+id+"' name='nickname'></td><lable id='"+labelText+"'></lable></td></tr>");
$('#providersFormElementsTable').append('<br />');
}

This one does what you want dynamically, it just needs the id and labelText to make it work, which actually must be the only dynamic variables as only they will be changing. Your DOM structure will always remain the same .

That is because when you call createProviderFormFields , it is a function call and hence it's returning an object for you. You will not be seeing the text box as it needs to be added . For that you need to strip individual content form the object, then construct the html from it.

It's much easier to construct just the html and change the id s of the label and input according to your needs.

The one and probably not so good way of achieving your goal would using global variables.

You could achieve that by adding global $myArr; to the beginning of your function. However note that using global variables is in most cases a bad idea and probably avoidable.

The much better way would be passing your array as an argument to your function:

function someFuntion($arr){
    $myVal = //some processing here to determine value of $myVal
    $arr[] = $myVal;
    return $arr;
}

$myArr = someFunction($myArr);

It is important to read the HTML specifications to truly understand what behavior is to be expected:

The HTML5 spec explicitly states what happens in implicit submissions:

A form element's default button is the first submit button in tree order whose form owner is that form element.

If the user agent supports letting the user submit a form implicitly (for example, on some platforms hitting the "enter" key while a text field is focused implicitly submits the form), then doing so for a form whose default button has a defined activation behavior must cause the user agent to run synthetic click activation steps on that default button.

This was not made explicit in the HTML4 spec, however browsers have already been implementing what is described in the HTML5 spec (which is why it's included explicitly).

Edit to add:

The simplest answer I can think of is to put your submit button as the first [type="submit"] item in the form, add padding to the bottom of the form with css, and absolutely position the submit button at the bottom where you'd like it.

andyras is completely correct. One minor addition, try this (for example)

plot 'ls.dat' using 4:xtic(1)

This will keep your datafile in the correct order, but also preserve your version tic labels on the x-axis.

Surprised that nobody has mentioned this which is my quick version for one-off scripts:

>>> x = 'gfgfdAAA1234ZZZuijjk'
>>> x.split('AAA')[1].split('ZZZ')[0]
'1234'

Another approach

Builder alert = new AlertDialog.Builder(ActivityName.this);
alert.setTitle("Doctor");
alert.setMessage("message");
alert.setPositiveButton("OK",null);
alert.show(); 

Bonus

AlertDialog.Builder builder = new AlertDialog.Builder(YourActivityName.this);
builder.setMessage("Message dialog with three buttons");

       builder.setPositiveButton("YES", new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
                //do things
           }
       });

      builder.setNegativeButton("NO", new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
                //do things
           }
       });

       builder.setNeutralButton("CANCEL", new DialogInterface.OnClickListener()     {
           public void onClick(DialogInterface dialog, int id) {
                //do things
           }
       });
AlertDialog alert = builder.create();
alert.show();

Now it is up to you to use one,two or three buttons..

In April 2017 a patch was merged into Safari, so it aligned with the other browsers. This was released with Safari 11.

https://bugs.webkit.org/show_bug.cgi?id=157010

You can use $pdf->GetX() and $pdf->GetY() to get current cooridnates and use them to insert image.

$pdf->Image($image1, 5, $pdf->GetY(), 33.78);

or even

$pdf->Image($image1, 5, null, 33.78);

(ALthough in first case you can add a number to create a bit of a space)

$pdf->Image($image1, 5, $pdf->GetY() + 5, 33.78);

I am pretty sure all you have to do is run

pip3 install jupyter

A way to get this can be print multiple end of lines ("\n") and simulate the clear screen. At the end clear, at most in the unix shell, not removes the previous content, only moves it up and if you make scroll down can see the previous content.

Here is a sample code:

for (int i = 0; i < 50; ++i) System.out.println();

If you can use pkg-config: pkg_search_module() can find OpenSSL for you.

# Search OpenSSL
find_package(PkgConfig REQUIRED)
pkg_search_module(OPENSSL REQUIRED openssl)

if( OPENSSL_FOUND )
    include_directories(${OPENSSL_INCLUDE_DIRS})
    message(STATUS "Using OpenSSL ${OPENSSL_VERSION}")
else()
    # Error; with REQUIRED, pkg_search_module() will throw an error by it's own
endif()

target_link_libraries(${YOUR_TARGET_HERE} ${OPENSSL_LIBRARIES})

For using "overflow: scroll" you must set "display:block" on thead and tbody. And that messes up column widths between them. But then you can clone the thead row with Javascript and paste it in the tbody as a hidden row to keep the exact col widths.

$('.myTable thead > tr').clone().appendTo('.myTable tbody').addClass('hidden-to-set-col-widths');

http://jsfiddle.net/Julesezaar/mup0c5hk/

<table class="myTable">
    <thead>
        <tr>
            <td>Problem</td>
            <td>Solution</td>
            <td>blah</td>
            <td>derp</td>
        </tr>
    </thead>
    <tbody></tbody>
</table>
<p>
  Some text to here
</p>

The css:

table {
  background-color: #aaa;
  width: 100%;
}

thead,
tbody {
  display: block; // Necessary to use overflow: scroll
}

tbody {
  background-color: #ddd;
  height: 150px;
  overflow-y: scroll;
}

tbody tr.hidden-to-set-col-widths,
tbody tr.hidden-to-set-col-widths td {
  visibility: hidden;
  height: 0;
  line-height: 0;
  padding-top: 0;
  padding-bottom: 0;
}

td {
  padding: 3px 10px;
}

I know its an old question. This problem can be easily reproduced if you try to reinitialize the Datatable again.

For example in your function somewhere you are calling $('#example').DataTable( { searching: false} ); again.

There is easy resolving this issue. Please follow the steps

1. Initialize the Datatable to a variable rather than directly initializing DataTable method.
   1. For Example Instead of calling $('#example').DataTable( { searching: false} ); try to declare it globally (or in scope of javascription that you are using) like this var table = $('#example').DataTable( { searching: false } );.
2. Now Whenever you are calling this method $('#example').DataTable( { searching: false} ); again then before calling it perform the following actions
   3. if (table != undefined && table != null) { table.destroy(); table = null; }
3. Once you have followed the steps above then go ahead with re-initializing the table with same variable without using var keyword (as you have already defined it) i.e table = $('#example').DataTable( { searching: false } );

I am developing Spring Boot application for a few weeks.. And i was gettig same error like below;

Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback. Thu Jan 18 14:12:11 AST 2018 There was an unexpected error (type=Not Found, status=404). No message available

When i get this error massage i realized my controller or rest controller class is note defined in my project. I mean our all controller packages aren't same package with main class which include @SpringBootApplication annotation.. I mean you need to add you controller package's name to @ComponentScan annotation to your main class which is inludes @SpringBootApplication annotation.If you write codes of below your problem will be solving... Most important thing is you have to add your all controller's package to @ComponentScan annotation like i did in the below

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan({ "com.controller.package1, com.controller.package2, com.controller.package3, com.controller.packageN", "controller", "service" } // If our Controller class or Service class is not in the same packages we have //to add packages's name like this...directory(package) with main class
public class MainApp {
    public static void main(String[] args) {
        SpringApplication.run(MainApp.class, args);
    }
}

I hope this codes are going to help someone...

If you find another way to solve this error or you have some suggestions for me, please write to comments... thanks...

Stream stream = new MemoryStream();

you can use MemoryStream

Reference: MemoryStream

As many of the answer suggesting better solution is to use ArrayList. ArrayList size is not fixed and it is easily manageable.

It is resizable-array implementation of the List interface. Implements all optional list operations, and permits all elements, including null. In addition to implementing the List interface, this class provides methods to manipulate the size of the array that is used internally to store the list.

Each ArrayList instance has a capacity. The capacity is the size of the array used to store the elements in the list. It is always at least as large as the list size. As elements are added to an ArrayList, its capacity grows automatically.

Note that this implementation is not synchronized.

ArrayList<String> scripts = new ArrayList<String>();
scripts.add("test1");
scripts.add("test2");
scripts.add("test3");

fileExists() is a method of FileSystemObject, not a global scope function.

You also have an issue with the delete, DeleteFile() is also a method of FileSystemObject.

Furthermore, it seems you are moving the file and then attempting to deal with the overwrite issue, which is out of order. First you must detect the name collision, so you can choose the rename the file or delete the collision first. I am assuming for some reason you want to keep deleting the new files until you get to the last one, which seemed implied in your question.

So you could use the block:

if NOT fso.FileExists(newname) Then  

    file.move fso.buildpath(OUT_PATH, newname)           

else

    fso.DeleteFile newname
    file.move fso.buildpath(OUT_PATH, newname)  

end if 

Also be careful that your string comparison with the = sign is case sensitive. Use strCmp with vbText compare option for case insensitive string comparison.

Thought this is old question, I think I have better solution

1. To use pip for a python 2.x environment, use this command -

   py -2 -m pip install -r requirements.txt

2. To use pip for python 3.x environment, use this command -

Update 03-Oct-19

new script that displays 10second countdown then launches chrome/chromiumn in fullscreen kiosk mode.

more updates to chrome required script update to allow autoplaying video with audio. Note --overscroll-history-navigation=0 isn't working currently will need to disable this flag by going to chrome://flags/#overscroll-history-navigation in your browser and setting to disabled.

@echo off
echo Countdown to application launch...
timeout /t 10
"C:\Program Files (x86)\chrome-win32\chrome.exe" --chrome --kiosk http://localhost/xxxx --incognito --disable-pinch --no-user-gesture-required --overscroll-history-navigation=0
exit

might need to set chrome://flags/#autoplay-policy if running an older version of chrome (60 below)

Update 11-May-16

There have been many updates to chrome since I posted this and have had to alter the script alot to keep it working as I needed.

Couple of issues with newer versions of chrome:

• built in pinch to zoom
• Chrome restore error always showing after forced shutdown
• auto update popup

Because of the restore error switched out to incognito mode as this launches a clear version all the time and does not save what the user was viewing and so if it crashes there is nothing to restore. Also the auto up in newer versions of chrome being a pain to try and disable I switched out to use chromium as it does not auto update and still gives all the modern features of chrome. Note make sure you download the top version of chromium this comes with all audio and video codecs as the basic version of chromium does not support all codecs.

Chromium download link

@echo off

echo Step 1 of 2: Waiting a few seconds before starting the Kiosk...

"C:\windows\system32\ping" -n 5 -w 1000 127.0.0.1 >NUL

echo Step 2 of 5: Waiting a few more seconds before starting the browser...

"C:\windows\system32\ping" -n 5 -w 1000 127.0.0.1 >NUL

echo Final 'invisible' step: Starting the browser, Finally...

"C:\Program Files (x86)\Google\Chromium\chrome.exe" --chrome --kiosk http://127.0.0.1/xxxx --incognito --disable-pinch --overscroll-history-navigation=0

exit

Outdated

I use this for exhibitions to lock down screens. I think its what your looking for.

• Start chrome and go to www.google.com drag and drop the url out onto the desktop
• rename it to something handy for this example google_homepage
• drop this now into your c directory, click on my computer c: and drop this file in there
• start chrome again go to settings and under on start up select open a specific page and set your home page here.

Next part is the script that I use to start close and restart chrome again in kiosk mode. The locations is where I have chrome installed so it might be abit different for you depending on your install.

Open your text editor of choice or just notepad and past the below code in, make sure its in the same format/order as below. Save it to your desktop as what ever you like so for this example chrome_startup_script.txt next right click it and rename, remove the txt from the end and put in bat instead. double click this to launch the script to see if its working correctly.

A command line box should appear and run through the script, chrome will start and then close down the reason to do this is to remove any error reports such as if the pc crashed, when chrome starts again without this it would show the yellow error bar at the top saying chrome did not shut down properly would you like to restore it. After a few seconds chrome should start again and in kiosk mode and will point to what ever homepage you have set.

@echo off
echo Step 1 of 5: Waiting a few seconds before starting the Kiosk...
"C:\windows\system32\ping" -n 31 -w 1000 127.0.0.1 >NUL
echo Step 2 of 5: Starting browser as a pre-start to delete error messages...
"C:\google_homepage.url"
echo Step 3 of 5: Waiting a few seconds before killing the browser task...
"C:\windows\system32\ping" -n 11 -w 1000 127.0.0.1 >NUL
echo Step 4 of 5: Killing the browser task gracefully to avoid session restore...
Taskkill /IM chrome.exe
echo Step 5 of 5: Waiting a few seconds before restarting the browser...
"C:\windows\system32\ping" -n 11 -w 1000 127.0.0.1 >NUL
echo Final 'invisible' step: Starting the browser, Finally...
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --kiosk --overscroll-history-navigation=0"
exit

Note: The number after the -n of the ping is the amount of seconds (minus one second) to wait before starting the link (or application in the next line)

Finally if this is all working then you can drag and drop the .bat file into the startup folder in windows and this script will launch each time windows starts.

Update:

With recent versions of chrome they have really got into enabling touch gestures, this means that swiping left or right on a touchscreen will cause the browser to go forward or backward in history. To prevent this we need to disable the history navigation on the back and forward buttons to do that add the following --overscroll-history-navigation=0 to the end of the script.

if you want to use md5 encryptioon you can do it in your php script

$pass = $_GET['pass'];

$newPass = md5($pass)

and then insert it into the database that way, however MD5 is a one way encryption method and is near on impossible to decrypt without difficulty

Read open as

open for inheritance in other modules

I repeat open for inheritance in other modules. So an open class is open for subclassing in other modules that include the defining module. Open vars and functions are open for overriding in other modules. Its the least restrictive access level. It is as good as public access except that something that is public is closed for inheritance in other modules.

From Apple Docs:

Open access applies only to classes and class members, and it differs from public access as follows:

1. Classes with public access, or any more restrictive access level, can be subclassed only within the module where they’re defined.

2. Class members with public access, or any more restrictive access level, can be overridden by subclasses only within the module where they’re defined.

3. Open classes can be subclassed within the module where they’re defined, and within any module that imports the module where they’re defined.

4. Open class members can be overridden by subclasses within the module where they’re defined, and within any module that imports the module where they’re defined.

You are starting a new setInterval at each call, without cancelling the previous one - probably you only meant to have a setTimeout

tail -f /var/log/syslog | grep process_name where process_name is the name of the process we are interested in

This is the functional programming method. It lifts the tuple expansion feature out of syntax sugar:

apply_tuple = lambda f, t: f(*t)

Redefine apply_tuple via curry to save a lot of partial calls in the long run:

from toolz import curry
apply_tuple = curry(apply_tuple)

Example usage:

from operator import add, eq
from toolz import thread_last

thread_last(
    [(1,2), (3,4)],
    (map, apply_tuple(add)),
    list,
    (eq, [3, 7])
)
# Prints 'True'

To dismiss the Viewcontroller called with the previous answers code by CmdSft

ViewController *viewController = [[ViewController alloc] init];    
[self presentViewController:viewController animated:YES completion:nil];

you can use

[self dismissViewControllerAnimated:YES completion: nil];

Yes, it's safe to delete these, although it may force a dynamic recompilation of any .NET applications you run on the server.

For background, see the Understanding ASP.NET dynamic compilation article on MSDN.

Judging by the declaration and description of the startsWith Java function, the "most straight forward way" to implement it in VBA would either be with Left:

Public Function startsWith(str As String, prefix As String) As Boolean
    startsWith = Left(str, Len(prefix)) = prefix
End Function

Or, if you want to have the offset parameter available, with Mid:

Public Function startsWith(str As String, prefix As String, Optional toffset As Integer = 0) As Boolean
    startsWith = Mid(str, toffset + 1, Len(prefix)) = prefix
End Function

While we submit spark jobs using spark-submit utility, there is an option --jars . Using this option, we can pass jar file to spark applications.

Variables in PHP are cast in three different type:

Public : values of this variable types are available in all scope and call on execution of you code. declare as: public $examTimeTable;

Private: Values of this type of variable are only available on only to the class it belongs to. private $classRoomComputers;

Protected: Values of this class only and only available when Access been granted in a form of inheritance or their child class. generally used :: to grant access by parent class

protected $familyWealth;

Usually a good place to start when you run into problems is the manual. The page on configuring email explains that there's a big difference between the PHP mail command running on MSWindows and on every other operating system; it's a good idea when posting a question to provide relevant information on how that part of your system is configured and what operating system it is running on.

Your PHP is configured to talk to an SMTP server - the default for an MSWindows machine, but either you have no MTA installed or it's blocking connections. While for a commercial website running your own MTA robably comes quite high on the list of things to do, it is not a trivial exercise - you really need to know what you're doing to get one configured and running securely. It would make a lot more sense in your case to use a service configured and managed by someone else.

Since you'll be connecting to a remote MTA using a gmail address, then you should probably use Gmail's server; you will need SMTP authenticaton and probably SSL support - neither of which are supported by the mail() function in PHP. There's a simple example here using swiftmailer with gmail or here's an example using phpmailer

Building on Terry's simple answer I made this into a basic jQuery function

$.prototype.disableTab = function() {
    this.each(function() {
        $(this).attr('tabindex', '-1');
    });
};

$('.unfocusable-element, .another-unfocusable-element').disableTab();

Yes, we can use jQuery in ReactJs. Here I will tell how we can use it using npm.

step 1: Go to your project folder where the package.json file is present via using terminal using cd command.

step 2: Write the following command to install jquery using npm : npm install jquery --save

step 3: Now, import $ from jquery into your jsx file where you need to use.

Example:

If you're running an MVC 3 application - in your solution explorer click the show all files icon and then under the Global.asax file there should be a file called YourProjectName.Publish.XML right-click it and then click "Browse With..." and select your favorite browser as the default.

In Bootstrap 4 it was renamed to .rounded-circle

Usage :

<div class="col-xs-7">
    <img src="img/gallery2.JPG" class="rounded-circle" alt="HelPic>
</div>

See migration docs from bootstrap.

To quickly and safely compare any two files:

if cmp --silent -- "$FILE1" "$FILE2"; then
  echo "files contents are identical"
else
  echo "files differ"
fi

It's readable, efficient, and works for any file names including "` $()

Because comparison doesn't work that way. 'Y' || 'y' is a logical-or operator; it returns 1 (true) if either of its arguments is true. Since 'Y' and 'y' are both true, you're comparing *answer with 1.

What you want is if(*answer == 'Y' || *answer == 'y') or perhaps:

switch (*answer) {
  case 'Y':
  case 'y':
    /* Code for Y */
    break;
  default:
    /* Code for anything else */
}

To add to @BrianBeech's answer, this is even more trimmed down in java 8:

jdbcTemplate.query("select string1,string2 from table where x=1", (ResultSet rs) -> {
    HashMap<String,String> results = new HashMap<>();
    while (rs.next()) {
        results.put(rs.getString("string1"), rs.getString("string2"));
    }
    return results;
});

         //Store the number of days after which you want to delete the logs.
         int Days = 30;

          // Storing the path of the directory where the logs are stored.
           String DirPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase).Substring(6) + "\\Log(s)\\";

          //Fetching all the folders.
            String[] objSubDirectory = Directory.GetDirectories(DirPath);

            //For each folder fetching all the files and matching with date given 
            foreach (String subdir in objSubDirectory)     
            {
                //Getting the path of the folder                 
                String strpath = Path.GetFullPath(subdir);
                //Fetching all the files from the folder.
                String[] strFiles = Directory.GetFiles(strpath);
                foreach (string files in strFiles)
                {
                    //For each file checking the creation date with the current date.
                    FileInfo objFile = new FileInfo(files);
                    if (objFile.CreationTime <= DateTime.Now.AddDays(-Days))
                    {
                        //Delete the file.
                        objFile.Delete();
                    }
                }

                //If folder contains no file then delete the folder also.
                if (Directory.GetFiles(strpath).Length == 0)
                {
                    DirectoryInfo objSubDir = new DirectoryInfo(subdir);
                    //Delete the folder.
                    objSubDir.Delete();
                }

            }

It is very simple if position is '0' then call onNothingSelected method in OnItemSelectedListener. It worked fine for me.

      spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

            **if (position == 0)
            {
                onNothingSelected(parent);
            }**
            else {

                String mechanicType = mechanicTpes[position];
                Toast.makeText(FirstUser.this, "Mechanic Tpye : "+mechanicType, Toast.LENGTH_SHORT).show();
            }




        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {
            Toast.makeText(FirstUser.this, "NOTHING SELECTED IN SPINNER", Toast.LENGTH_SHORT).show();


        }
    });

There is no default database for user. There is default database for current session.

You can get it using DATABASE() function -

SELECT DATABASE();

And you can set it using USE statement -

USE database1;

You should set it manually - USE db_name, or in the connection string.

You need to initialize the list first:

protected List<string> list = new List<string>();

The short and sweet version:

• ($) calls the function which is its left-hand argument on the value which is its right-hand argument.
• (.) composes the function which is its left-hand argument on the function which is its right-hand argument.

I wrote a class for that too. http://blog.another-d-mention.ro/programming/read-load-files-from-zip-in-javascript/ You can load basic assets such as javascript/css/images directly from the zip using class methods. Hope it helps

When a fresh install is needed, I create a Windows "user environment variable " named HOME and assigns it the path of wherever "My Documents" reside.

The cygwin installer detects the HOME variable, automatically translates this into a cygpath and selects this it to be my ~ directory.

This has worked fine for every workstation I have used professionally the last 5 years (about 3 or 4, Win7). I have always been the only user on these machines, cannot say what the effect is.

Here's my 2 cents:

The sequence Start New Instance->Close Current Instance should work even for the applications that don't allow running multiple copies simultaneously as in this case the new instance may be passed a command-line argument which will indicate that there is a restart in progress so checking for other instances running will not be necessary. Waiting for the first instance to actually finish my be implemented too if it's absolutely imperative that no two intstances are running in parallel.

If you are still inside the vi editor, you might be in a different mode from the one you want. Hit ESC a couple of times (until it rings or flashes) and then "i" to enter INSERT mode or "a" to enter APPEND mode (they are the same, just start before or after current character).

If you are back at the command prompt, make sure you can locate the file, then navigate to that directory and perform the mentioned "vi helloWorld.txt". Once you are in the editor, you'll need to check the vi reference to know how to perform the editions you want (you may want to google "vi reference" or "vi cheat sheet").

Once the edition is done, hit ESC again, then type :wq to save your work or :q! to quit without saving.

For quick reference, here you have a text-based cheat sheet.

There is also:

info all-registers

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

Handy Swift extension:

import AudioToolbox

extension SystemSoundID {
    static func playFileNamed(fileName: String, withExtenstion fileExtension: String) {
        var sound: SystemSoundID = 0
        if let soundURL = NSBundle.mainBundle().URLForResource(fileName, withExtension: fileExtension) {
            AudioServicesCreateSystemSoundID(soundURL, &sound)
            AudioServicesPlaySystemSound(sound)
        }
    }
}

Then, from anywhere in your app (remember to import AudioToolbox), you can call

SystemSoundID.playFileNamed("sound", withExtenstion: "mp3")

to play "sound.mp3"

You need to add your servlet-api.jar to the build path of your project. Have a look here for how to do that.

Try:

import numpy as np
dist = np.array([1,2,3,4,5])
r = 2
dr = 3
np.where(np.logical_and(dist> r, dist<=r+dr))

Output: (array([2, 3]),)

You can see Logic functions for more details.

You can use this code to send CSV file data into an array:

import numpy as np
csv = np.genfromtxt('test.csv', delimiter=",")
print(csv)

You might want to start with scapy.

Parse Querystring into a NameValueCollection. Remove an item. And use the toString to convert it back to a querystring.

using System.Collections.Specialized;

NameValueCollection filteredQueryString = System.Web.HttpUtility.ParseQueryString(Request.QueryString.ToString());
filteredQueryString.Remove("appKey");

var queryString = '?'+ filteredQueryString.ToString();

In React-Native we have an Option called Dimensions

Include Dimensions at the top var where you have include the Image,and Text and other components.

Then in your Stylesheets you can use as below,

ex: {
width: Dimensions.get('window').width,
height: Dimensions.get('window').height
}

In this way you can get the device window and height.

It depends on your application and its use as to the level of security you need.

In terms of security, you should be validating all values you get from the querystring or post parameters, to ensure they're valid.

You may also wish to add logging for others, including analysis of weblogs so you can determine if an attempt to hack your system is occuring.

I don't believe it's possible to inject javascript into a URL and have this run, unless your application is using parameters without validating them first.

Assuming you alredy tried to "Add Reference..." as explained above and did not succeed, you can have a look here. They say you have to meet some prerequisites: - .NET 3.5 SP1 - Windows Installer 4.5

EDIT: According to this post it is a known issue.

And this could be the solution you're looking for :)

The previous functions didn't work for me, so I've made another function that use the same logic of one of the answers above: parse the formula in the cell to find the referenced range of cells to examine and than look for the coloured cells. You can find a detailed description here: Google Script count coloured with reference, but the code is below:

function countColoured(reference) {
  var sheet = SpreadsheetApp.getActiveSheet();
  var formula = SpreadsheetApp.getActiveRange().getFormula();
  var args = formula.match(/=\w+\((.*)\)/i)[1].split('!');
  try {
    if (args.length == 1) {
      var range = sheet.getRange(args[0]);
    }
    else {
      sheet = ss.getSheetByName(args[0].replace(/'/g, ''));
      range = sheet.getRange(args[1]);
    }
  }
  catch(e) {
    throw new Error(args.join('!') + ' is not a valid range');
  }
  var c = 0;
  var numRows = range.getNumRows();
  var numCols = range.getNumColumns();
  for (var i = 1; i <= numRows; i++) {
    for (var j = 1; j <= numCols; j++) {
      c = c + ( range.getCell(i,j).getBackground() == "#ffffff" ? 0 : 1 );
    }
  }
  return c > 0 ? c : "" ;
}

pipes in Angular2 are similar to pipes on the command line. The output of each preceding value is fed into the filter after the pipe which makes it easy to chain filters as well like this:

<template *ngFor="#item of itemsList">
    <div *ngIf="conditon(item)">{item | filter1 | filter2}</div>
</template>

You can also use a media query with javascript.

const mq = window.matchMedia( "(min-width: 960px)" );

if (mq.matches) {
       alert("window width >= 960px");
} else {
     alert("window width < 960px");
}

Make sure that jQuery is using the $ variable, and its not another javascript framework.

Check your doctype: Validate your html, sometimes browsers don't see stuff in quirks mode, or when they encouter malformed html.

Also ensure that jquery.validate.js file is correct.

You can download it below:

Try to run npm run dev in powershell. This worked for me.

Try writting the lambda with the same conditions as the delegate. like this:

  List<AnalysisObject> analysisObjects = 
    analysisObjectRepository.FindAll().Where(
    (x => 
       (x.ID == packageId)
    || (x.Parent != null && x.Parent.ID == packageId)
    || (x.Parent != null && x.Parent.Parent != null && x.Parent.Parent.ID == packageId)
    ).ToList();

This is problem with Java and Flash Player. Install the latest Java and Flash Player, and the problem will be resolved. If not, then install Mozilla Firefox, it will auto install the updates required.

It appears that the up-to-date answer to this is to not use filter-branch directly (at least git itself does not recommend it anymore), and defer that work to an external tool. In particular, git-filter-repo is currently recommended. The author of that tool provides arguments on why using filter-branch directly can lead to issues.

Most of the multi-line scripts above to remove dir from the history could be re-written as:

git filter-repo --path dir --invert-paths

The tool is more powerful than just that, apparently. You can apply filters by author, email, refname and more (full manpage here). Furthermore, it is fast. Installation is easy - it is distributed in a variety of formats.

Using your code with some random data, this would work:

fig, axs = plt.subplots(2,5, figsize=(15, 6), facecolor='w', edgecolor='k')
fig.subplots_adjust(hspace = .5, wspace=.001)

axs = axs.ravel()

for i in range(10):

    axs[i].contourf(np.random.rand(10,10),5,cmap=plt.cm.Oranges)
    axs[i].set_title(str(250+i))

The layout is off course a bit messy, but that's because of your current settings (the figsize, wspace etc).

two of the best options are

$(this).parent("div:first")

$(this).parent().closest('div')

and of course you can find the class attr by

$(this).parent("div:first").attr("class")

$(this).parent().closest('div').attr("class")

To elaborate on @Bakuriu's answer above, I've found that this enables me to catch a runtime warning in a similar fashion to how I would catch an error warning, printing out the warning nicely:

import warnings

with warnings.catch_warnings():
    warnings.filterwarnings('error')
    try:
        answer = 1 / 0
    except Warning as e:
        print('error found:', e)

You will probably be able to play around with placing of the warnings.catch_warnings() placement depending on how big of an umbrella you want to cast with catching errors this way.

Try this

 try
                {
                    Bitmap bmp = null;
                    URL url = new URL("Your_URL");
                    URLConnection conn = url.openConnection();
                    bmp = BitmapFactory.decodeStream(conn.getInputStream());
                    File f = new File(Environment.getExternalStorageDirectory(),System.currentTimeMillis() + ".jpg");
                    if(f.exists())
                        f.delete();
                    f.createNewFile();
                    Bitmap bitmap = bmp;
                    ByteArrayOutputStream bos = new ByteArrayOutputStream();
                    bitmap.compress(Bitmap.CompressFormat.PNG, 0 /*ignored for PNG*/, bos);
                    byte[] bitmapdata = bos.toByteArray();
                    FileOutputStream fos = new FileOutputStream(f);
                    fos.write(bitmapdata);
                    fos.flush();
                    fos.close();
                    Log.e(TAG, "imagepath: "+f );
                }
                catch (Exception e)
                {
                    e.printStackTrace();
                }

import itertools

foos=[1.0, 2.0, 3.0, 4.0, 5.0]
bars=[1, 2, 3]

print zip(foos, itertools.cycle([bars]))

int dp1 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 1,
            context.getResources().getDisplayMetrics());

tv.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
dp1 * 100)); // if you want to set layout height to 100dp

llview.addView(tv);

I am siteConfiguration class for calling all my appSetting like this way. I share it if it will help anyone.

add the following code at the "web.config"

<configuration>
   <configSections>
     <!-- some stuff omitted here -->
   </configSections>
   <appSettings>
      <add key="appKeyString" value="abc" />
      <add key="appKeyInt" value="123" />  
   </appSettings>
</configuration>

Now you can define a class for getting all your appSetting value. like this

using System; 
using System.Configuration;
namespace Configuration
{
   public static class SiteConfigurationReader
   {
      public static String appKeyString  //for string type value
      {
         get
         {
            return ConfigurationManager.AppSettings.Get("appKeyString");
         }
      }

      public static Int32 appKeyInt  //to get integer value
      {
         get
         {
            return ConfigurationManager.AppSettings.Get("appKeyInt").ToInteger(true);
         }
      }

      // you can also get the app setting by passing the key
      public static Int32 GetAppSettingsInteger(string keyName)
      {
          try
          {
            return Convert.ToInt32(ConfigurationManager.AppSettings.Get(keyName));
        }
        catch
        {
            return 0;
        }
      }
   }
}

Now add the reference of previous class and to access a key call like bellow

string appKeyStringVal= SiteConfigurationReader.appKeyString;
int appKeyIntVal= SiteConfigurationReader.appKeyInt;
int appKeyStringByPassingKey = SiteConfigurationReader.GetAppSettingsInteger("appKeyInt");

json = File.ReadAllText(System.AppDomain.CurrentDomain.BaseDirectory + "App_Data\\" +download_file[0]);
DataTable dt = (DataTable)JsonConvert.DeserializeObject(json, (typeof(DataTable)));

I wrote this function:

public static String encode(@NonNull String uriString) {
    if (TextUtils.isEmpty(uriString)) {
        Assert.fail("Uri string cannot be empty!");
        return uriString;
    }
    // getQueryParameterNames is not exist then cannot iterate on queries
    if (Build.VERSION.SDK_INT < 11) {
        return uriString;
    }

    // Check if uri has valid characters
    // See https://tools.ietf.org/html/rfc3986
    Pattern allowedUrlCharacters = Pattern.compile("([A-Za-z0-9_.~:/?\\#\\[\\]@!$&'()*+,;" +
            "=-]|%[0-9a-fA-F]{2})+");
    Matcher matcher = allowedUrlCharacters.matcher(uriString);
    String validUri = null;
    if (matcher.find()) {
        validUri = matcher.group();
    }
    if (TextUtils.isEmpty(validUri) || uriString.length() == validUri.length()) {
        return uriString;
    }

    // The uriString is not encoded. Then recreate the uri and encode it this time
    Uri uri = Uri.parse(uriString);
    Uri.Builder uriBuilder = new Uri.Builder()
            .scheme(uri.getScheme())
            .authority(uri.getAuthority());
    for (String path : uri.getPathSegments()) {
        uriBuilder.appendPath(path);
    }
    for (String key : uri.getQueryParameterNames()) {
        uriBuilder.appendQueryParameter(key, uri.getQueryParameter(key));
    }
    String correctUrl = uriBuilder.build().toString();
    return correctUrl;
}

Here is a simplistic example of streaming a file:

using System.IO;
using Microsoft.AspNetCore.Mvc;

[HttpGet("{id}")]
public async Task<FileStreamResult> Download(int id)
{
    var path = "<Get the file path using the ID>";
    var stream = File.OpenRead(path);
    return new FileStreamResult(stream, "application/octet-stream");
}

Note:

Be sure to use FileStreamResult from Microsoft.AspNetCore.Mvc and not from System.Web.Mvc.

Try updating the line to:

ocr.Init(@"C:\", "eng", false); // the path here should be the parent folder of tessdata

In SQL Server do like this:

where cast(columnName as date) = cast(getdate() -1 as date)

You should cast both sides of the expression to date to avoid issues with time formatting.

If you need to control interval in more detail, then you should try something like:

declare @start datetime = cast(getdate() - 1 as date)
declare @end datetime = cast(getdate() - 1 as date)
set @end = dateadd(second, 86399, @end)

Stack is much faster. It literally only uses a single instruction on most architectures, in most cases, e.g. on x86:

sub esp, 0x10

(That moves the stack pointer down by 0x10 bytes and thereby "allocates" those bytes for use by a variable.)

Of course, the stack's size is very, very finite, as you will quickly find out if you overuse stack allocation or try to do recursion :-)

Also, there's little reason to optimize the performance of code that doesn't verifiably need it, such as demonstrated by profiling. "Premature optimization" often causes more problems than it's worth.

My rule of thumb: if I know I'm going to need some data at compile-time, and it's under a few hundred bytes in size, I stack-allocate it. Otherwise I heap-allocate it.

So here is an idea!

Since it seemed to work somewhere else.

install python-virtualenv and optionally you can install virtualenv-wrapper (which is pretty cool to create projects and so on)

In each env, you might have different versions of eggs. In other word, you could have sqlalchemy 1 and sqlaclhemy 1.5 in two different envs and they won't conflict with each others. It seems that you have a problem with your currently installed eggs.

So here we go:

virtualenv --no-site-packages foo
source foo/bin/activate

The parameter --no-site-packages will create a virtualenv and not use the packages already installed on your computer. It's pretty much like a bare python install.

source foo/bin/activate loads the virtualenv.

It's not that really userfriendly. And that's why http://www.doughellmann.com/projects/virtualenvwrapper/ exists.

That said, you should see somthing like thant in your terminal "(foo)user@domain$:" once your virtualenv is activated. It means that you can go on!

Then you have to do.

python setup.py develop of your project. It should download and install dependencies of your project in the virtualenv located in foo. If you need to install anything else, please use pip or easy_install without using sudo. When using virtualenv, you almost never need to use sudo. Sudo will install package in your global python install while it's not required and not really desirable.

If something happens in your virtualenv, you can always delete it and create a new one. This is no big deal. No need to mess with anything. Doesn't work? start over, do pip install -U if needed, define the versions if needed and so on.

Last but not least, in the other answers, it seems that the import changed. If the new versions for flask-sqlalchemy is located somewhere else, you should update your import or install the version you used to use.

I would do it the following way:

>>> x = np.array([[1,0,0], [0,2,0], [1,1,0]])
>>> x
array([[1, 0, 0],
       [0, 2, 0],
       [1, 1, 0]])
>>> np.nonzero(x)
(array([0, 1, 2, 2]), array([0, 1, 0, 1]))

# if you want it in coordinates
>>> x[np.nonzero(x)]
array([1, 2, 1, 1])
>>> np.transpose(np.nonzero(x))
array([[0, 0],
       [1, 1],
       [2, 0],
       [2, 1])

Had the same issue saying /Pods/Pods-resources.sh: No such file or directory even after files etc related to pods were removed.

Got rid of it by going to target->Build phases and then removing the build phase "Copy Pod Resources".

This little bit different idea. But it will useful to you. I have used sub query to inside the linq main query.

Problem:

Let say we have document table. Schema as follows schema : document(name,version,auther,modifieddate) composite Keys : name,version

So we need to get latest versions of all documents.

soloution

 var result = (from t in Context.document
                          where ((from tt in Context.document where t.Name == tt.Name
                                orderby tt.Version descending select new {Vesion=tt.Version}).FirstOrDefault()).Vesion.Contains(t.Version)
                          select t).ToList();

add this to you CSS:

html, body
{
    height: 100%;
}

working Fiddle

when you say to wrap to be 100%, 100% of what? of its parent (body), so his parent has to have some height.

and the same goes for body, his parent his html. html parent his the viewport.. so, by setting them both to 100%, wrap can also have a percentage height.

also: the elements have some default padding/margin, that causes them to span a little more then the height you applied to them. (causing a scroll bar) you can use

*
{
    padding: 0;
    margin: 0;
}

to disable that.

Look at That Fiddle

The proper interval to get one second is 1000. The Interval property is the time between ticks in milliseconds:

MSDN: Timer.Interval Property

So, it's not the interval that you set that is wrong. Check the rest of your code for something like changing the interval of the timer, or binding the Tick event multiple times.

^[0-9]{1,2}[:.,-]?po$

Add any other allowable non-alphanumeric characters to the middle brackets to allow them to be parsed as well.

Faced this scenario using Git Bash.

Our repository has multiple branches and each branch has a different commit cycle and merge happens once in a while. Old_Branch was used as a parent for New_Branch

Old_Branch was updated with some changes which required to be merged with New_Branch

Was using below pull command without any branch to get all sources from all branches.

git pull origin

Strangely this doesn't pull all the commits from all the branches. Had thought it so as the indicated shows almost all branches and tags.

So to fix this had checked out the Old_Branch pulled the latest using

git checkout Old_Branch

git pull origin Old_Branch

Now checked out New_Branch

git checkout New_Branch

Pulled it to be sure

git pull origin New_Branch

git merge Old_Branch

And viola got conflicts to fix from Old_Branch to New_Branch :) which was expected

It seems as of now, the only solution is still to install SublimeREPL.

To extend on Raghav's answer, it can be quite annoying to have to go into the Tools->SublimeREPL->Python->Run command every time you want to run a script with input, so I devised a quick key binding that may be handy:

To enable it, go to Preferences->Key Bindings - User, and copy this in there:

[
    {"keys":["ctrl+r"] , 
    "caption": "SublimeREPL: Python - RUN current file",
    "command": "run_existing_window_command", 
    "args":
        {
            "id": "repl_python_run",
            "file": "config/Python/Main.sublime-menu"
        }
    },
]

Naturally, you would just have to change the "keys" argument to change the shortcut to whatever you'd like.

If you take a look at the sources for django.contrib.auth.views.password_reset you'll see that it uses RequestContext. The upshot is, you can use Context Processors to modify the context which may allow you to inject the information that you need.

The b-list has a good introduction to context processors.

Edit (I seem to have been confused about what the actual question was):

You'll notice that password_reset takes a named parameter called template_name:

def password_reset(request, is_admin_site=False, 
            template_name='registration/password_reset_form.html',
            email_template_name='registration/password_reset_email.html',
            password_reset_form=PasswordResetForm, 
            token_generator=default_token_generator,
            post_reset_redirect=None):

Check password_reset for more information.

... thus, with a urls.py like:

from django.conf.urls.defaults import *
from django.contrib.auth.views import password_reset

urlpatterns = patterns('',
     (r'^/accounts/password/reset/$', password_reset, {'template_name': 'my_templates/password_reset.html'}),
     ...
)

django.contrib.auth.views.password_reset will be called for URLs matching '/accounts/password/reset' with the keyword argument template_name = 'my_templates/password_reset.html'.

Otherwise, you don't need to provide any context as the password_reset view takes care of itself. If you want to see what context you have available, you can trigger a TemplateSyntax error and look through the stack trace find the frame with a local variable named context. If you want to modify the context then what I said above about context processors is probably the way to go.

In summary: what do you need to do to use your own template? Provide a template_name keyword argument to the view when it is called. You can supply keyword arguments to views by including a dictionary as the third member of a URL pattern tuple.

It's now the css property:

word-break: break-all

Using a single sed

echo "/var/cpanel/users/joebloggs:DNS9=domain.com" | sed 's/.*\/\(.*\):.*/\1/'

In Python the definition of package is very simple. Like Java the hierarchical structure and the directory structure are the same. But you have to have __init__.py in a package. I will explain the __init__.py file with the example below:

package_x/
|--  __init__.py
|--    subPackage_a/
|------  __init__.py
|------  module_m1.py
|--    subPackage_b/
|------  __init__.py
|------  module_n1.py
|------  module_n2.py
|------  module_n3.py

__init__.py can be empty, as long as it exists. It indicates that the directory should be regarded as a package. Of course, __init__.py can also set the appropriate content.

If we add a function in module_n1:

def function_X():
    print "function_X in module_n1"
    return

After running:

>>>from package_x.subPackage_b.module_n1 import function_X
>>>function_X()

function_X in module_n1 

Then we followed the hierarchy package and called module_n1 the function. We can use __init__.py in subPackage_b like this:

__all__ = ['module_n2', 'module_n3']

After running:

>>>from package_x.subPackage_b import * 
>>>module_n1.function_X()

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named module_n1

Hence using * importing, module package is subject to __init__.py content.

It's the other way around: = and == are for string comparisons, -eq is for numeric ones. -eq is in the same family as -lt, -le, -gt, -ge, and -ne, if that helps you remember which is which.

== is a bash-ism, by the way. It's better to use the POSIX =. In bash the two are equivalent, and in plain sh = is the only one guaranteed to work.

$ a=foo
$ [ "$a" = foo ]; echo "$?"       # POSIX sh
0
$ [ "$a" == foo ]; echo "$?"      # bash specific
0
$ [ "$a" -eq foo ]; echo "$?"     # wrong
-bash: [: foo: integer expression expected
2

(Side note: Quote those variable expansions! Do not leave out the double quotes above.)

If you're writing a #!/bin/bash script then I recommend using [[ instead. The doubled form has more features, more natural syntax, and fewer gotchas that will trip you up. Double quotes are no longer required around $a, for one:

$ [[ $a == foo ]]; echo "$?"      # bash specific
0

Another solution would be as below where the list is placed under a drop-down button.

  <button class="btn dropdown-toggle btn-primary btn-sm" data-toggle="dropdown"
    >Markets<span class="caret"></span></button>

      {{ form.markets }}
    </ul>

You're inserting values for OperationId that is an identity column.

You can turn on identity insert on the table like this so that you can specify your own identity values.

SET IDENTITY_INSERT Table1 ON

INSERT INTO Table1
/*Note the column list is REQUIRED here, not optional*/
            (OperationID,
             OpDescription,
             FilterID)
VALUES      (20,
             'Hierachy Update',
             1)

SET IDENTITY_INSERT Table1 OFF 

Intent.FLAG_ACTIVITY_FORWARD_RESULT?

If set and this intent is being used to launch a new activity from an existing one, then the reply target of the existing activity will be transfered to the new activity.

Above one has some syntax error, Please use following on oracle:

SELECT ROUND (totalSeconds / (24 * 60 * 60), 1) TotalTimeSpendIn_DAYS,
  ROUND (totalSeconds      / (60 * 60), 0) TotalTimeSpendIn_HOURS,
  ROUND (totalSeconds      / 60) TotalTimeSpendIn_MINUTES,
  ROUND (totalSeconds) TotalTimeSpendIn_SECONDS
FROM
  (SELECT ROUND ( EXTRACT (DAY FROM timeDiff) * 24 * 60 * 60 + EXTRACT (HOUR FROM timeDiff) * 60 * 60 + EXTRACT (MINUTE FROM timeDiff) * 60 + EXTRACT (SECOND FROM timeDiff)) totalSeconds
  FROM
    (SELECT TO_TIMESTAMP(TO_CHAR( date2 , 'yyyy-mm-dd HH24:mi:ss'), 'yyyy-mm-dd HH24:mi:ss') - TO_TIMESTAMP(TO_CHAR(date1, 'yyyy-mm-dd HH24:mi:ss'),'yyyy-mm-dd HH24:mi:ss') timeDiff
    FROM TABLENAME
    )
);

Using executeUpdate() on the Query API is faster because it bypasses the persistent context .However , by-passing persistent context would cause the state of instance in the memory and the actual values of that record in the DB are not synchronized.

Consider the following example :

 Employee employee= (Employee)entityManager.find(Employee.class , 1);
 entityManager
     .createQuery("update Employee set name = \'xxxx\' where id=1")
     .executeUpdate();

After flushing, the name in the DB is updated to the new value but the employee instance in the memory still keeps the original value .You have to call entityManager.refresh(employee) to reload the updated name from the DB to the employee instance.It sounds strange if your codes still have to manipulate the employee instance after flushing but you forget to refresh() the employee instance as the employee instance still contains the original values.

Normally , executeUpdate() is used in the bulk update process as it is faster due to bypassing the persistent context

The right way to update an entity is that you just set the properties you want to updated through the setters and let the JPA to generate the update SQL for you during flushing instead of writing it manually.

   Employee employee= (Employee)entityManager.find(Employee.class ,1);
   employee.setName("Updated Name");

It depends on the recursion level for triggers currently set on the DB.

If you do this:

SP_CONFIGURE 'nested_triggers',0
GO
RECONFIGURE
GO

Or this:

ALTER DATABASE db_name
SET RECURSIVE_TRIGGERS OFF

That trigger above won't be called again, and you would be safe (unless you get into some kind of deadlock; that could be possible but maybe I'm wrong).

Still, I do not think this is a good idea. A better option would be using an INSTEAD OF trigger. That way you would avoid executing the first (manual) update over the DB. Only the one defined inside the trigger would be executed.

An INSTEAD OF INSERT trigger would be like this:

CREATE TRIGGER setDescToUpper ON part_numbers
INSTEAD OF INSERT
AS
BEGIN
    INSERT INTO part_numbers (
        colA,
        colB,
        part_description
    ) SELECT
        colA,
        colB,
        UPPER(part_description)
    ) FROM
        INSERTED
END
GO

This would automagically "replace" the original INSERT statement by this one, with an explicit UPPER call applied to the part_description field.

An INSTEAD OF UPDATE trigger would be similar (and I don't advise you to create a single trigger, keep them separated).

Also, this addresses @Martin comment: it works for multirow inserts/updates (your example does not).

I was facing similar problems trying to do some dat import on an intermediate schema (that later we move on to the final one). As we rely on things like extensions (for example PostGIS), the "run_insert" sql file did not fully solved the problem.

After a while, we've found that at least with Postgres 9.3 the solution is far easier... just create your SQL script always specifying the schema when refering to the table:

CREATE TABLE "my_schema"."my_table" (...); COPY "my_schema"."my_table" (...) FROM stdin;

This way using psql -f xxxxx works perfectly, and you don't need to change search_paths nor use intermediate files (and won't hit extension schema problems).

You can access the function itself using arguments.callee ^[MDN]:

if (counter>0) {
    arguments.callee(counter-1);
}

This will break in strict mode, however.

The OP's questions about canonical form and how it can improve performance of the equals method can both be answered by extending the example provided in Effective Java.

Consider the following class:

public final class CaseInsensitiveString {

  private final String s;

  public CaseInsensitiveString(String s) {
    this.s = Objects.requireNonNull(s);
  }

  @Override 
  public boolean equals(Object o) {
    return o instanceof CaseInsensitiveString && ((CaseInsensitiveString) o).s.equalsIgnoreCase(s);
  }
}

The equals method in this example has added cost by using String's equalsIgnoreCase method. As mentioned in the text

you may want to store a canonical form of the field so the equals method can do a cheap exact comparison on canonical forms rather than a more costly nonstandard comparison.

What does Joshua Bloch mean when he says canonical form? Well, I think Dónal's concise answer is very appropriate. We can store the underlying String field in the CaseInsensitiveString example in a standard way, perhaps the uppercase form of the String. Now, you can reference this canonical form of the CaseInsensitiveString, its uppercase variant, and perform cheap evaluations in your equals and hashcode methods.

You can use the Base64 Android class:

String encodedImage = Base64.encodeToString(byteArrayImage, Base64.DEFAULT);

You'll have to convert your image into a byte array though. Here's an example:

Bitmap bm = BitmapFactory.decodeFile("/path/to/image.jpg");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bm.compress(Bitmap.CompressFormat.JPEG, 100, baos); // bm is the bitmap object
byte[] b = baos.toByteArray();

* Update *

If you're using an older SDK library (because you want it to work on phones with older versions of the OS) you won't have the Base64 class packaged in (since it just came out in API level 8 AKA version 2.2).

Check this article out for a workaround:

I did use urlmon.dll in the end. I thought there would be an easier way but this works. I include the code to help anyone else and allow me to find it again if I need it.

using System.Runtime.InteropServices;

...

    [DllImport(@"urlmon.dll", CharSet = CharSet.Auto)]
    private extern static System.UInt32 FindMimeFromData(
        System.UInt32 pBC,
        [MarshalAs(UnmanagedType.LPStr)] System.String pwzUrl,
        [MarshalAs(UnmanagedType.LPArray)] byte[] pBuffer,
        System.UInt32 cbSize,
        [MarshalAs(UnmanagedType.LPStr)] System.String pwzMimeProposed,
        System.UInt32 dwMimeFlags,
        out System.UInt32 ppwzMimeOut,
        System.UInt32 dwReserverd
    );

    public static string getMimeFromFile(string filename)
    {
        if (!File.Exists(filename))
            throw new FileNotFoundException(filename + " not found");

        byte[] buffer = new byte[256];
        using (FileStream fs = new FileStream(filename, FileMode.Open))
        {
            if (fs.Length >= 256)
                fs.Read(buffer, 0, 256);
            else
                fs.Read(buffer, 0, (int)fs.Length);
        }
        try
        {
            System.UInt32 mimetype;
            FindMimeFromData(0, null, buffer, 256, null, 0, out mimetype, 0);
            System.IntPtr mimeTypePtr = new IntPtr(mimetype);
            string mime = Marshal.PtrToStringUni(mimeTypePtr);
            Marshal.FreeCoTaskMem(mimeTypePtr);
            return mime;
        }
        catch (Exception e)
        {
            return "unknown/unknown";
        }
    }

GROUP BY 1

I've never known GROUP BY to support using ordinals, only ORDER BY. Either way, only MySQL supports GROUP BY's not including all columns without aggregate functions performed on them. Ordinals aren't recommended practice either because if they're based on the order of the SELECT - if that changes, so does your ORDER BY (or GROUP BY if supported).

There's no need to run GROUP BY on the contents when you're using UNION - UNION ensures that duplicates are removed; UNION ALL is faster because it doesn't - and in that case you would need the GROUP BY...

Your query only needs to be:

SELECT a.id,
       a.time
  FROM dbo.TABLE_A a
UNION
SELECT b.id,
       b.time
  FROM dbo.TABLE_B b

Possible reason: The reason can be that this image is currently used by a running container. In such case, you can list running containers, stop the relevant container and then remove the image:

docker ps
docker stop <containerid>
docker rm <containerid>
docker rmi <imageid>

If you cannnot find container by docker ps, you can use this to list all already exited containers and remove them.

docker ps -a | grep 60afe4036d97
docker rm <containerid>

Note: Be careful of deleting all exited containers at once in case you use Volume-Only containers. These stay in Exit state, but contains useful data.

Monkey is right, according to the link given by monkey

Basically it's a way to map a combined/minified file back to an unbuilt state. When you build for production, along with minifying and combining your JavaScript files, you generate a source map which holds information about your original files. When you query a certain line and column number in your generated JavaScript you can do a lookup in the source map which returns the original location.

I am not sure if it is angular's fault that no map files were generated. But you can turn off source map files by unchecking this option in chrome console setting

In the code you have posted there would be no advantages, as you are misusing the StringBuilder. You build the same String in both cases. Using StringBuilder you can avoid the + operation on Strings using the append method. You should use it this way:

return new StringBuilder("select id1, ").append(" id2 ").append(" from ").append(" table").toString();

In Java, the String type is an inmutable sequence of characters, so when you add two Strings the VM creates a new String value with both operands concatenated.

StringBuilder provides a mutable sequence of characters, which you can use to concat different values or variables without creating new String objects, and so it can sometimes be more efficient than working with strings

This provides some useful features, as changing the content of a char sequence passed as parameter inside another method, which you can't do with Strings.

private void addWhereClause(StringBuilder sql, String column, String value) {
   //WARNING: only as an example, never append directly a value to a SQL String, or you'll be exposed to SQL Injection
   sql.append(" where ").append(column).append(" = ").append(value);
}

I was having a situation in ASP.NET 4.0 where my session would be reset on every page request (and my SESSION_START code would run on each page request). This didn't happen to every user for every session, but it usually happened, and when it did, it would happen on each page request.

My web.config sessionState tag had the same setting as the one mentioned above.

cookieless="false"

When I changed it to the following...

cookieless="UseCookies"

... the problem seemed to go away. Apparently true|false were old choices from ASP.NET 1. Starting in ASP.Net 2.0, the enumerated choices started being available. I guess these options were deprecated. The "false" value has never presented a problem in the past - I've only noticed in on ASP.NET 4.0. I don't know if something has changed in 4.0 that no longer supports it correctly.

Also, I just found this out not long ago. Since the problem was intermittent before, I suppose I could still encounter it, but so far it's working with this new setting.

I've had this same dependency problem and I also know that you can include the VS 8.0 DLLs (release only! not debug!---and your program has to be release, too) in a folder of the appropriate name, in the parent folder with your .exe:

How to: Deploy using XCopy (MSDN)

Also note that things are guaranteed to go awry if you need to have C++ and C code in the same statically linked .exe because you will get linker conflicts that can only be resolved by ignoring the correct libXXX.lib and then linking dynamically (DLLs).

Lastly, with a different toolset (VC++ 6.0) things "just work", since Windows 2000 and above have the correct DLLs installed.

with this code, the id will not appear on the link

    document.querySelectorAll('a[href^="#"]').forEach(anchor => {
        anchor.addEventListener('click', function (e) {

            document.querySelector(this.getAttribute('href')).scrollIntoView({
                behavior: 'smooth'
            });
        });
    });

Like docs say:

When the command line does not specify where to push with the <repository> argument, branch.*.remote configuration for the current branch is consulted to determine where to push. If the configuration is missing, it defaults to origin.

Activity is the base class of all other activities, I don't think it will be deprecated. The relationship among them is:

Activity <- FragmentActivity <- AppCompatActivity <- ActionBarActivity

'<-' means inheritance here. The reference said ActionBarActivity is deprecated, use AppCompatActivity instead.

So basically, using AppCompatActivity is always the right choice. The differences between them are:

• Activity is the basic one.
• Based on Activity, FragmentActivity provides the ability to use Fragment.
• Based on FragmentActivity, AppCompatActivity provides features to ActionBar.

This should do the trick in a cross-platform way (so long as you're not using the interpreter or something):

import os, sys
non_symbolic=os.path.realpath(sys.argv[0])
program_filepath=os.path.join(sys.path[0], os.path.basename(non_symbolic))

sys.path[0] is the directory that your calling script is in (the first place it looks for modules to be used by that script). We can take the name of the file itself off the end of sys.argv[0] (which is what I did with os.path.basename). os.path.join just sticks them together in a cross-platform way. os.path.realpath just makes sure if we get any symbolic links with different names than the script itself that we still get the real name of the script.

I don't have a Mac; so, I haven't tested this on one. Please let me know if it works, as it seems it should. I tested this in Linux (Xubuntu) with Python 3.4. Note that many solutions for this problem don't work on Macs (since I've heard that __file__ is not present on Macs).

Note that if your script is a symbolic link, it will give you the path of the file it links to (and not the path of the symbolic link).

.click events only work when element gets rendered and are only attached to elements loaded when the DOM is ready.

.on events are dynamically attached to DOM elements, which is helpful when you want to attach an event to DOM elements that are rendered on ajax request or something else (after the DOM is ready).

must means: The clause (query) must appear in matching documents. These clauses must match, like logical AND.

should means: At least one of these clauses must match, like logical OR.

Basically they are used like logical operators AND and OR. See this.

Now in a bool query:

must means: Clauses that must match for the document to be included.

should means: If these clauses match, they increase the _score; otherwise, they have no effect. They are simply used to refine the relevance score for each document.

Yes you can use multiple filters inside must.

The solution consists in a regex pattern matching open and closing parenthesis

String str = "Your(String)";
// parameter inside split method is the pattern that matches opened and closed parenthesis, 
// that means all characters inside "[ ]" escaping parenthesis with "\\" -> "[\\(\\)]"
String[] parts = str.split("[\\(\\)]");
for (String part : parts) {
   // I print first "Your", in the second round trip "String"
   System.out.println(part);
}

Writing in Java 8's style, this can be solved in this way:

Arrays.asList("Your(String)".split("[\\(\\)]"))
    .forEach(System.out::println);

I hope it is clear.

This will set the execution policy for the current user (stored in HKEY_CURRENT_USER) rather than the local machine (HKEY_LOCAL_MACHINE). This is useful if you don't have administrative control over the computer.

1. As per https://msdn.microsoft.com/en-us/library/ms180065.aspx, "DBCC USEROPTIONS reports an isolation level of 'read committed snapshot' when the database option READ_COMMITTED_SNAPSHOT is set to ON and the transaction isolation level is set to 'read committed'. The actual isolation level is read committed."

2. Also in SQL Server Management Studio, in database properties under Options->Miscellaneous there is "Is Read Committed Snapshot On" option status

You can read a CSV file with headers into a NumPy structured array with np.genfromtxt. For example:

import numpy as np

csv_fname = 'file.csv'
with open(csv_fname, 'w') as fp:
    fp.write("""\
"A","B","C","D","E","F","timestamp"
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291111964948E12
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291113113366E12
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291120650486E12
""")

# Read the CSV file into a Numpy record array
r = np.genfromtxt(csv_fname, delimiter=',', names=True, case_sensitive=True)
print(repr(r))

which looks like this:

array([(611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29111196e+12),
       (611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29111311e+12),
       (611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29112065e+12)],
      dtype=[('A', '<f8'), ('B', '<f8'), ('C', '<f8'), ('D', '<f8'), ('E', '<f8'), ('F', '<f8'), ('timestamp', '<f8')])

You can access a named column like this r['E']:

array([1715.37476, 1715.37476, 1715.37476])

Note: this answer previously used np.recfromcsv to read the data into a NumPy record array. While there was nothing wrong with that method, structured arrays are generally better than record arrays for speed and compatibility.

I'm a begin fan of js array's reduce function.

const myArray =[1, 2, 3, 5, 2, 8, 9, 2];
const count = myArray.reduce((count, num) => num === 2 ? count + 1 : count, 0)

In fact if you really want to get fancy you can create a count function on the Array prototype. Then you can reuse it.

Array.prototype.count = function(filterMethod) {
  return this.reduce((count, item) => filterMethod(item)? count + 1 : count, 0);
} 

Then do

const myArray =[1, 2, 3, 5, 2, 8, 9, 2]
const count = myArray.count(x => x==2)

If you are using a LinearLayout you should call myView.bringToFront() and after you should call parentView.requestLayout() and parentView.invalidate() to force the parent to redraw with the new child order.

You can go from String (hex) to byte array to String as UTF-8(?). Make sure your hex string does not have leading spaces and stuff.

public static byte[] hexStringToByteArray(String hex) {
    int l = hex.length();
    byte[] data = new byte[l / 2];
    for (int i = 0; i < l; i += 2) {
        data[i / 2] = (byte) ((Character.digit(hex.charAt(i), 16) << 4)
                + Character.digit(hex.charAt(i + 1), 16));
    }
    return data;
}

Usage:

String b = "0xfd00000aa8660b5b010006acdc0100000101000100010000";
byte[] bytes = hexStringToByteArray(b);
String st = new String(bytes, StandardCharsets.UTF_8);
System.out.println(st);

According to this posting by the lead Jenkins developer, Kohsuke Kawaguchi, in 2009, there is no group support for the built-in Jenkins user database. Group support is only usable when integrating Jenkins with LDAP or Active Directory. This appears to be the same in 2012.

However, as Vadim wrote in his answer, you don't need group support for the built-in Jenkins user database, thanks to the Role strategy plug-in.

If you propagate the exception by declaring the throws directive in the signature of the current method, then somewhere up the line or call stack a try/catch construct must be used to handle the exception.

Try this regular expression:

\w*Id\b

\w* allows word characters in front of Id and the \b ensures that Id is at the end of the word (\b is word boundary assertion).

Do this:

<ToggleButton 
        android:id="@+id/toggle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/check"   <!--check.xml-->
        android:layout_margin="10dp"
        android:textOn=""
        android:textOff=""
        android:focusable="false"
        android:focusableInTouchMode="false"
        android:layout_centerVertical="true"/>

create check.xml in drawable folder

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- When selected, use grey -->
    <item android:drawable="@drawable/selected_image"
          android:state_checked="true" />
    <!-- When not selected, use white-->
    <item android:drawable="@drawable/unselected_image"
        android:state_checked="false"/>

 </selector>

In your public View getView method change return null; to return convertView;.

I had a similar problem. I needed to get the last version of page content translation, in other words - to get that specific record which has highest number in version column. So I select all records ordered by version and then take the first row from result (by using LIMIT clause).

SELECT *
FROM `page_contents_translations`
ORDER BY version DESC
LIMIT 1

This worked for me: .\mongod --dbpath c:......

It really depends on the situation, for me its in fpm as I'm using PHP5-FPM. A solution to your problem could be a universal php.ini and then using a symbolic link created like:

ln -s /etc/php5/php.ini php.ini

Then any modifications you make will be in one general .ini file. This is probably not really the best solution though, you might want to look into modifying some configuration so that you literally use one file, on one location. Not multiple locations hacked together.

Goto xampp folder in local drive c, click on mysql folder, then click on bin and finally click on "mysqladmin" application. Then go back and refresh your browser and the problem is solved.

As mentioned above markdown itself leaves you hanging on this. However, depending on the implementation there are some workarounds:

At least one version of MD considers <div> to be a block level tag but <DIV> is just text. All broswers however are case insensitive. This allows you to keep the syntax simplicity of MD, at the cost of adding div container tags.

So the following is a workaround:

<DIV class=foo>

  Paragraphs here inherit class foo from above.

</div>

The downside of this is that the output code has <p> tags wrapping the <div> lines (both of them, the first because it's not and the second because it doesn't match. No browser fusses about this that I've found, but the code won't validate. MD tends to put in spare <p> tags anyway.

Several versions of markdown implement the convention <tag markdown="1"> in which case MD will do the normal processing inside the tag. The above example becomes:

<div markdown="1" class=foo>

  Paragraphs here inherit class foo from above.

</div>

The current version of Fletcher's MultiMarkdown allows attributes to follow the link if using referenced links.

Try deleting the adbkey file from C/.android folder

and then run the commands as mentioned above i.e.

adb kill-server, adb start-server and adb devices

.

If you don't explicitly cast one of the two values to a float before doing the division then an integer division will be used (so that's why you get 0). You just need one of the two operands to be a floating point value, so that the normal division is used (and other integer value is automatically turned into a float).

Just try with

float completed = 50000.0f;

and it will be fine.

Actually, I did something like this:

    select case myconfigtable.valpar
       when 'WEEK' then to_char(next_day(datetime-7,'Monday'),'DD/MM/YYYY')|| ' - '|| to_char(next_day(datetime,'Sunday'),'DD/MM/YYYY')
       when 'MONTH' then to_char(to_date(yearweek,'yyyyMM'),'DD/MM/YYYY')  || ' - '|| to_char(last_day(to_date(yearweek,'yyyyMM')),'DD/MM/YYYY')
       else 'NA'
       end
from
(
select to_date(YEAR||'01','YYYYMM') + 7 * (WEEK - 1) datetime, yearweek
       from
       (
       select substr(yearweek,1,4) YEAR,
              to_number(substr(yearweek,5)) WEEK,
              yearweek
       from (select '201018' yearweek from dual
            )
       )
), myconfigtable myconfigtable
 where myconfigtable.codpar='TYPEOFPERIOD'

Build a list from the columns and remove the column you don't want to calculate the Z score for:

In [66]:
cols = list(df.columns)
cols.remove('ID')
df[cols]

Out[66]:
   Age  BMI  Risk  Factor
0    6   48  19.3       4
1    8   43  20.9     NaN
2    2   39  18.1       3
3    9   41  19.5     NaN
In [68]:
# now iterate over the remaining columns and create a new zscore column
for col in cols:
    col_zscore = col + '_zscore'
    df[col_zscore] = (df[col] - df[col].mean())/df[col].std(ddof=0)
df
Out[68]:
   ID  Age  BMI  Risk  Factor  Age_zscore  BMI_zscore  Risk_zscore  \
0  PT    6   48  19.3       4   -0.093250    1.569614    -0.150946

   Factor_zscore  
0              1  
1            NaN  
2             -1  
3            NaN  

use List<T>. Internally it uses arrays and arrays do use contiguous memory.

this is how I do it

function run_ajax(obj) {
    $.ajax({
        type:"POST",
        url: prefix,
        data: obj.pdata,
        dataType: 'json',
        error: function(data) {
            //do error stuff
        },
        success: function(data) {

            if(obj.func){
                obj.func(data); 
            }

        }
    });
}

alert_func(data){
    //do what you want with data
}

var obj= {};
obj.pdata = {sumbit:"somevalue"}; // post variable data
obj.func = alert_func;
run_ajax(obj);

Noting down my situation here may be useful to somebody,

I have to send a custom intent with multiple intent extras to a broadcast receiver in Android P,

The details are,

Receiver name: com.hardian.testservice.TestBroadcastReceiver

Intent action = "com.hardian.testservice.ADD_DATA"

intent extras are,

1. "text"="test msg",
2. "source"= 1,

Run the following in command line.

adb shell "am broadcast -a com.hardian.testservice.ADD_DATA --es text 'test msg' --es source 1 -n com.hardian.testservice/.TestBroadcastReceiver"

Hope this helps.

Compile the Release version as .exe file, then just copy onto a machine with a suitable version of .NET Framework installed and run it there. The .exe file is located in the bin\Release subfolder of the project folder.

Once I found an xsd link on the top of the wsdl. Like this wsdl example from the web, you can see a link xsd1. The server has to be running to see it.

<?xml version="1.0"?>
<definitions name="StockQuote"
             targetNamespace="http://example.com/stockquote.wsdl"
             xmlns:tns="http://example.com/stockquote.wsdl"
             xmlns:xsd1="http://example.com/stockquote.xsd"
             xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
             xmlns="http://schemas.xmlsoap.org/wsdl/">

I tried with a rest client.

it works fine. I retrieve 200 OK with a good body.

Why do you set a status code in your request? and multiple declaration "Accept" with Accept:application/json,application/json,application/jsonrequest. just a statement is enough.
