Since I landed here when looking for a solution to my own problem, I'll share my solution here, in case others land here as well.

I was connecting fine to SQL Server until my machine was moved to another office on another domain. Then, after the switch, I was getting this error regarding the target principal name. What fixed it was connecting using a fully qualified name such as: server.domain.com. And actually, once I connected to the first server that way, I could connect to other servers using just the server name (without the full qualification), but your mileage may vary.

I recently set up a script that does this.

As David Brabant pointed out, you can use the System.Net.WebRequest class to do an HTTP request.

To check whether it is operational, you should use the following example code:

# First we create the request.
$HTTP_Request = [System.Net.WebRequest]::Create('http://google.com')

# We then get a response from the site.
$HTTP_Response = $HTTP_Request.GetResponse()

# We then get the HTTP code as an integer.
$HTTP_Status = [int]$HTTP_Response.StatusCode

If ($HTTP_Status -eq 200) {
    Write-Host "Site is OK!"
}
Else {
    Write-Host "The Site may be down, please check!"
}

# Finally, we clean up the http request by closing it.
If ($HTTP_Response -eq $null) { } 
Else { $HTTP_Response.Close() }

Running the command prompt or Powershell ISE as an administrator fixed this for me.

Just access the Priority property of the object returned from the pipeline:

$var = (Get-WSManInstance -enumerate wmicimv2/win32_process).Priority

(This won't work if Get-WSManInstance returns multiple objects.²)

For the second question: to get two properties there are several options, problably the simplest is to have have one variable* containing an object with two separate properties:

$var = (Get-WSManInstance -enumerate wmicimv2/win32_process | select -first 1 Priority, ProcessID)

and then use, assuming only one process:

$var.Priority

and

$var.ProcessID

If there are multiple processes $var will be an array which you can index, so to get the properties of the first process (using the array literal syntax @(...) so it is always a collection¹):

$var = @(Get-WSManInstance -enumerate wmicimv2/win32_process | select -first 1 Priority, ProcessID)

and then use:

$var[0].Priority
$var[0].ProcessID

¹ PowerShell helpfully for the command line, but not so helpfully in scripts has some extra logic when assigning the result of a pipeline to a variable: if no objects are returned then set $null, if one is returned then that object is assigned, otherwise an array is assigned. Forcing an array returns an array with zero, one or more (respectively) elements.

² This changes in PowerShell V3 (at the time of writing in Release Candidate), using a member property on an array of objects will return an array of the value of those properties.

The guys have given the simple solution, which will do be you should have a look at the help - it's good, looks like a lot in one go but it's actually quick to read:

Everyone explained the topic very well. There is one more point i would like add about .load() method.

As per Load document if you add suffixed selector in data url then it will not execute scripts in loading content.

Working Plunker

            $(document).ready(function(){
                $("#secondPage").load("mySecondHtmlPage.html #content");
            })

On the other hand, after removing selector in url, scripts in new content will run. Try this example

after removing #content in url in index.html file

            $(document).ready(function(){
                $("#secondPage").load("mySecondHtmlPage.html");
            })

There is no such in-built feature provided by other methods in discussion.

Please note that adding the get_author function would slow the list_display in the admin, because showing each person would make a SQL query.

To avoid this, you need to modify get_queryset method in PersonAdmin, for example:

def get_queryset(self, request):
    return super(PersonAdmin,self).get_queryset(request).select_related('book')

Before: 73 queries in 36.02ms (67 duplicated queries in admin)

After: 6 queries in 10.81ms

With RxJS 5.5+, the catch operator is now deprecated. You should now use the catchError operator in conjunction with pipe.

RxJS v5.5.2 is the default dependency version for Angular 5.

For each RxJS Operator you import, including catchError you should now import from 'rxjs/operators' and use the pipe operator.

Example of catching error for an Http request Observable

import { Observable } from 'rxjs';
import { catchError } from 'rxjs/operators';
...

export class ExampleClass {
  constructor(private http: HttpClient) {
    this.http.request(method, url, options).pipe(
      catchError((err: HttpErrorResponse) => {
        ...
      }
    )
  }
  ...
}

Notice here that catch is replaced with catchError and the pipe operator is used to compose the operators in similar manner to what you're used to with dot-chaining.

See the rxjs documentation on pipable (previously known as lettable) operators for more info.

Here's another one:

Note that in general, IDE's like Visual Studio will markup a comment in the context of the current language, by selecting the text you wish to turn into a comment, and then using the Ctrl+K Ctrl+C shortcut, or if you are using Resharper / Intelli-J style shortcuts, then Ctrl+/.

Server side Comments:

Razor .cshtml

Like so:

@* Comment goes here *@

.aspx
For those looking for the older .aspx view (and Asp.Net WebForms) server side comment syntax:

<%-- Comment goes here --%>

Client Side Comments

HTML Comment

<!-- Comment goes here -->

Javascript Comment

// One line Comment goes Here
/* Multiline comment
   goes here */

As OP mentions, although not displayed on the browser, client side comments will still be generated for the page / script file on the server and downloaded by the page over HTTP, which unless removed (e.g. minification), will waste I/O, and, since the comment can be viewed by the user by viewing the page source or intercepting the traffic with the browser's Dev Tools or a tool like Fiddler or Wireshark, can also pose a security risk, hence the preference to use server side comments on server generated code (like MVC views or .aspx pages).

The fulfillment value of a promise parallels the return value of a function and the rejection reason of a promise parallels the thrown exception of a function. Functions cannot return multiple values so promises must not have more than 1 fulfillment value.

Is "Module1" part of the same workbook that contains "moduleController"?
If not, you could call public method of "Module1" using Application.Run someWorkbook.xlsm!methodOfModule.

Change

$data[$parts[0]] = $parts[1];

to

if ( ! isset($parts[1])) {
   $parts[1] = null;
}

$data[$parts[0]] = $parts[1];

or simply:

$data[$parts[0]] = isset($parts[1]) ? $parts[1] : null;

Not every line of your file has a colon in it and therefore explode on it returns an array of size 1.

According to php.net possible return values from explode:

Returns an array of strings created by splitting the string parameter on boundaries formed by the delimiter.

If delimiter is an empty string (""), explode() will return FALSE. If delimiter contains a value that is not contained in string and a negative limit is used, then an empty array will be returned, otherwise an array containing string will be returned.

This is not possible directly, because chronologically, WHERE happens before SELECT, which always is the last step in the execution chain.

You can do a sub-select and filter on it:

SELECT * FROM
(
  SELECT A.identifier
    , A.name
    , TO_NUMBER(DECODE( A.month_no
      , 1, 200803 
      , 2, 200804 
      , 3, 200805 
      , 4, 200806 
      , 5, 200807 
      , 6, 200808 
      , 7, 200809 
      , 8, 200810 
      , 9, 200811 
      , 10, 200812 
      , 11, 200701 
      , 12, 200702
      , NULL)) as MONTH_NO
    , TO_NUMBER(TO_CHAR(B.last_update_date, 'YYYYMM')) as UPD_DATE
  FROM table_a A
    , table_b B
  WHERE A.identifier = B.identifier
) AS inner_table
WHERE 
  MONTH_NO > UPD_DATE

Interesting bit of info moved up from the comments:

There should be no performance hit. Oracle does not need to materialize inner queries before applying outer conditions -- Oracle will consider transforming this query internally and push the predicate down into the inner query and will do so if it is cost effective. – Justin Cave

It works for me on Vista. Some things to try:

1. Replace find with the fully-qualified path of the find command. find is a common tool name. There's a unix find that is very differet from the Windows built-in find. like this:
   FOR /f %%a in ('dir ^|%windir%\system32\find.exe /i "myfile.txt"') DO SET fileDate=%%a

2. examine the output of the command in a cmd.exe window. To do that, You need to replace the %% with %.
   FOR /f %a in ('dir ^|c:\windows\system32\find.exe /i "myfile.txt"') DO SET fileDate=%a
   That may give you some ideas.

3. If that shows up as blank, then again, at a command prompt, try this:

   dir | c:\windows\system32\find.exe /i "myfile.txt"

This should show you what you need to see.

If you still can't figure it out from that, edit your post to include what you see from these commands and someone will help you.

In short, both have pros and cons.

On one hand, it has advantages to use ==, as described in the other answers.

On the other hand, if you for any reason replace the enums with a different approach (normal class instances), having used == bites you. (BTDT.)

I fixed this by restarting VS.

I had opened a config file in another instance of VS and apparently sth went nuts...

I have a solution of this problem

Install this package:

npm install rxjs@6 rxjs-compat@6 --save

then import this library

import 'rxjs/add/operator/map'

finally restart your ionic project then

ionic serve -l

Maybe try ".=" indead of "="?

$xml="l";
$xml.="vv";

will give you "lvv";

I answer to myself. As suggested by Vadzim, I must consider the jboss-logging.xml file and insert these lines:

<logger category="org.hibernate">
     <level name="TRACE"/>
</logger>

Instead of DEBUG level I wrote TRACE. Now don't look only the console but open the server.log file (debug messages aren't sent to the console but you can configure this mode!).

Based on the answers provided, I decided to make a quick plugin to do this:

(function($){
    $.fn.moveTo = function(selector){
        return this.each(function(){
            var cl = $(this).clone();
            $(cl).appendTo(selector);
            $(this).remove();
        });
    };
})(jQuery);

Usage:

$('#nodeToMove').moveTo('#newParent');

This will do what you want. It reads the fourth field into a local variable, and then sets the actual field value to NULL, if the local variable ends up containing an empty string:

LOAD DATA INFILE '/tmp/testdata.txt'
INTO TABLE moo
FIELDS TERMINATED BY ","
LINES TERMINATED BY "\n"
(one, two, three, @vfour, five)
SET four = NULLIF(@vfour,'')
;

If they're all possibly empty, then you'd read them all into variables and have multiple SET statements, like this:

LOAD DATA INFILE '/tmp/testdata.txt'
INTO TABLE moo
FIELDS TERMINATED BY ","
LINES TERMINATED BY "\n"
(@vone, @vtwo, @vthree, @vfour, @vfive)
SET
one = NULLIF(@vone,''),
two = NULLIF(@vtwo,''),
three = NULLIF(@vthree,''),
four = NULLIF(@vfour,'')
;

With a small change of the markup, here's my approach (I've just inserted a span inside the paragraph):

.marquee {
  width: 450px;
  margin: 0 auto;
  overflow: hidden;
  box-sizing: border-box;
}

.marquee span {
  display: inline-block;
  width: max-content;

  padding-left: 100%;
  /* show the marquee just outside the paragraph */
  will-change: transform;
  animation: marquee 15s linear infinite;
}

.marquee span:hover {
  animation-play-state: paused
}


@keyframes marquee {
  0% { transform: translate(0, 0); }
  100% { transform: translate(-100%, 0); }
}


/* Respect user preferences about animations */

@media (prefers-reduced-motion: reduce) {
  .marquee span {
    animation-iteration-count: 1;
    animation-duration: 0.01; 
    /* instead of animation: none, so an animationend event is 
     * still available, if previously attached.
     */
    width: auto;
    padding-left: 0;
  }
}

<p class="marquee">
   <span>
       When I had journeyed half of our life's way, I found myself
       within a shadowed forest, for I had lost the path that 
       does not stray. – (Dante Alighieri, <i>Divine Comedy</i>. 
       1265-1321)
   </span>
   </p>

No hardcoded values — dependent on paragraph width — have been inserted.

The animation applies the CSS3 transform property (use prefixes where needed) so it performs well.

If you need to insert a delay just once at the beginning then also set an animation-delay. If you need instead to insert a small delay at every loop then try to play with an higher padding-left (e.g. 150%)

I had the same problem. It was because my JSON response contains some special characters and the server file was not encoded with UTF-8, so the Ajax call considered that this was not a valid JSON response.

The first is a constant pointer to a char and the second is a pointer to a constant char. You didn't touch all the cases in your code:

char * const pc1 = &a; /* You can't make pc1 point to anything else */
const char * pc2 = &a; /* You can't dereference pc2 to write. */

*pc1 = 'c' /* Legal. */
*pc2 = 'c' /* Illegal. */

pc1 = &b; /* Illegal, pc1 is a constant pointer. */
pc2 = &b; /* Legal, pc2 itself is not constant. */

var address = IPAddress.Parse("10.0.11.174").GetAddressBytes();
long m_Address = ((address[3] << 24 | address[2] << 16 | address[1] << 8 | address[0]) & 0x0FFFFFFFF);

Doing some sort of ser/deser or encode/decode trick seems ugly and requires you to remember what exactly you did when you are trying to use the constant. I think the class private static variable with accessor is a decent solution, but I'll do you one better. Just have a public static getter method that returns the definition of the constant array. This requires a minimum of extra code and the array definition cannot be accidentally modified.

class UserRoles {
    public static function getDefaultRoles() {
        return array('guy', 'development team');
    }
}

initMyRoles( UserRoles::getDefaultRoles() );

If you want to really make it look like a defined constant you could give it an all caps name, but then it would be confusing to remember to add the '()' parentheses after the name.

class UserRoles {
    public static function DEFAULT_ROLES() { return array('guy', 'development team'); }
}

//but, then the extra () looks weird...
initMyRoles( UserRoles::DEFAULT_ROLES() );

I suppose you could make the method global to be closer to the define() functionality you were asking for, but you really should scope the constant name anyhow and avoid globals.

HTML does not support a dropdown list with checkboxes. You can have a dropdown list, or a checkbox list. You could possibly fake a dropdowncheckbox list using javascript and hiding divs, but that would be less reliable than just a standard checkbox list.

There are of course 3rd party controls that look like a dropdown checkboxlist, but they are using the div tricks.

you could also use a double listbox, which handles multi select by moving items back and forth between two lists. This has the added benefit of being easily to see all the selected items at once, even though the list of total items is long

(Imagine a list of every city in the world, with only the first and last selected)

This code should work:

>>> iter = (i for i in range(50))
>>> sum(1 for _ in iter)
50

Although it does iterate through each item and count them, it is the fastest way to do so.

It also works for when the iterator has no item:

>>> sum(1 for _ in range(0))
0

Of course, it runs forever for an infinite input, so remember that iterators can be infinite:

>>> sum(1 for _ in itertools.count())
[nothing happens, forever]

Also, be aware that the iterator will be exhausted by doing this, and further attempts to use it will see no elements. That's an unavoidable consequence of the Python iterator design. If you want to keep the elements, you'll have to store them in a list or something.

You need to put the change the input type to hidden, all the functions of it work but it is not visible on the page

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

as long as the input type is set to that you can change the rest. Good Luck!!

Try to specify an 8-bit charset in both conversions. ISO-8859-1 for instance.

You are using the wrong iteration counter, replace inp.charAt(i) with inp.charAt(j).

If you're attempting to start a SERVICE rather than activity, this worked for me:

Intent intent = new Intent();
intent.setClassName("com.example.otherapplication", "com.example.otherapplication.ServiceName");
context.startService(intent);

If you use the intent.setComponent(...) method as mentioned in other answers, you may get an "Implicit intents with startService are not safe" warning.

I think you may be getting tripped up on the sheet protection. I streamlined your code a little and am explicitly setting references to the workbook and worksheet objects. In your example, you explicitly refer to the workbook and sheet when you're setting the TxtRng object, but not when you unprotect the sheet.

Try this:

Sub varchanger()

    Dim wb As Workbook
    Dim ws As Worksheet
    Dim TxtRng  As Range

    Set wb = ActiveWorkbook
    Set ws = wb.Sheets("Sheet1")
    'or ws.Unprotect Password:="yourpass"
    ws.Unprotect

    Set TxtRng = ws.Range("A1")
    TxtRng.Value = "SubTotal"
    'http://stackoverflow.com/questions/8253776/worksheet-protection-set-using-ws-protect-but-doesnt-unprotect-using-the-menu
    ' or ws.Protect Password:="yourpass"
    ws.Protect

End Sub

If I run the sub with ws.Unprotect commented out, I get a run-time error 1004. (Assuming I've protected the sheet and have the range locked.) Uncommenting the line allows the code to run fine.

NOTES:

1. I'm re-setting sheet protection after writing to the range. I'm assuming you want to do this if you had the sheet protected in the first place. If you are re-setting protection later after further processing, you'll need to remove that line.
2. I removed the error handler. The Excel error message gives you a lot more detail than Err.number. You can put it back in once you get your code working and display whatever you want. Obviously you can use Err.Description as well.
3. The Cells(1, 1) notation can cause a huge amount of grief. Be careful using it. Range("A1") is a lot easier for humans to parse and tends to prevent forehead-slapping mistakes.

I think the correct access method is using the index:

df_2.loc[:,'D'] = df_2['B']

if ($name )
{
    #since undef and '' both evaluate to false 
    #this should work only when string is defined and non-empty...
    #unless you're expecting someting like $name="0" which is false.
    #notice though that $name="00" is not false
}

Android ("vanilla" android without custom launchers and touch interfaces) does not allow changing of the application icon, because it is sealed in the .apk tightly once the program is compiled. There is no way to change it to a 'drawable' programmatically using standard APIs. You may achieve your goal by using a widget instead of an icon. Widgets are customisable. Please read this :http://www.cnet.com/8301-19736_1-10278814-251.html and this http://developer.android.com/guide/topics/appwidgets/index.html. Also look here: https://github.com/jgilfelt/android-viewbadger. It can help you.

As for badge numbers. As I said before - there is no standard way for doing this. But we all know that Android is an open operating system and we can do everything we want with it, so the only way to add a badge number - is either to use some 3-rd party apps or custom launchers, or front-end touch interfaces: Samsung TouchWiz or Sony Xperia's interface. Other answers use this capabilities and you can search for this on stackoverflow, e.g. here. But I will repeat one more time: there is no standard API for this and I want to say it is a bad practice. App's icon notification badge is an iOS pattern and it should not be used in Android apps anyway. In Andrioid there is a status bar notifications for these purposes:http://developer.android.com/guide/topics/ui/notifiers/notifications.html So, if Facebook or someone other use this - it is not a common pattern or trend we should consider. But if you insist anyway and don't want to use home screen widgets then look here, please:

How does Facebook add badge numbers on app icon in Android?

As you see this is not an actual Facebook app it's TouchWiz. In vanilla android this can be achieved with Nova Launcher http://forums.androidcentral.com/android-applications/199709-how-guide-global-badge-notifications.html So if you will see icon badges somewhere, be sure it is either a 3-rd party launcher or touch interface (frontend wrapper). May be sometime Google will add this capability to the standard Android API.

Using cv2

import cv2
image = cv2.imread(tiff_file.tif)
cv2.imshow('tif image',image)

Setting android:background and android:button of the RadioButton like the accepted answer didn't work for me. The drawable image was being displayed as a background(eventhough android:button was being set to transparent ) to the radio button text as

android:background="@drawable/radiobuttonstyle"
    android:button="@android:color/transparent"

so gave radiobutton as the custom drawable radiobuttonstyle.xml

<RadioButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="true"
    android:text="Maintenance"
    android:id="@+id/radioButton1"
    android:button="@drawable/radiobuttonstyle"
      />

and radiobuttonstyle.xml is as follows

<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_checked="true" android:drawable="@drawable/ic_radio_checked"></item>
  <item android:state_checked="false" android:drawable="@drawable/ic_radio_unchecked"></item>
</selector>

and after this radiobutton with custom button style worked.

A bit late to the party, but Krux has created a script for this, called Postscribe. We were able to use this to get past this issue.

You can make use of the beforeunload event in JavaScript.

Using vanilla JavaScript you could do something like:

window.onbeforeunload = function() {
  localStorage.removeItem(key);
  return '';
};

That will delete the key before the browser window/tab is closed and prompts you to confirm the close window/tab action. I hope that solves your problem.

NOTE: The onbeforeunload method should return a string.

TL;DR

>>> import pandas as pd
>>> df = pd.DataFrame({'Position':[1,2,3,4,5], 'Letter':['a', 'b', 'c', 'd', 'e']})
>>> dict(sorted(df.values.tolist())) # Sort of sorted... 
{'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5}
>>> from collections import OrderedDict
>>> OrderedDict(df.values.tolist())
OrderedDict([('a', 1), ('b', 2), ('c', 3), ('d', 4), ('e', 5)])

In Long

Explaining solution: dict(sorted(df.values.tolist()))

Given:

df = pd.DataFrame({'Position':[1,2,3,4,5], 'Letter':['a', 'b', 'c', 'd', 'e']})

[out]:

 Letter Position
0   a   1
1   b   2
2   c   3
3   d   4
4   e   5

Try:

# Get the values out to a 2-D numpy array, 
df.values

[out]:

array([['a', 1],
       ['b', 2],
       ['c', 3],
       ['d', 4],
       ['e', 5]], dtype=object)

Then optionally:

# Dump it into a list so that you can sort it using `sorted()`
sorted(df.values.tolist()) # Sort by key

Or:

# Sort by value:
from operator import itemgetter
sorted(df.values.tolist(), key=itemgetter(1))

[out]:

[['a', 1], ['b', 2], ['c', 3], ['d', 4], ['e', 5]]

Lastly, cast the list of list of 2 elements into a dict.

dict(sorted(df.values.tolist())) 

[out]:

{'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5}

Answering @sbradbio comment:

If there are multiple values for a specific key and you would like to keep all of them, it's the not the most efficient but the most intuitive way is:

from collections import defaultdict
import pandas as pd

multivalue_dict = defaultdict(list)

df = pd.DataFrame({'Position':[1,2,4,4,4], 'Letter':['a', 'b', 'd', 'e', 'f']})

for idx,row in df.iterrows():
    multivalue_dict[row['Position']].append(row['Letter'])

[out]:

>>> print(multivalue_dict)
defaultdict(list, {1: ['a'], 2: ['b'], 4: ['d', 'e', 'f']})

Objects don't have a .length property.

A simple solution if you know you don't have to worry about hasOwnProperty checks, would be to do this:

Object.keys(data).length;

If you have to support IE 8 or lower, you'll have to use a loop, instead:

var length= 0;
for(var key in data) {
    if(data.hasOwnProperty(key)){
        length++;
    }
}

Stacked by this issue and have resolved it in 2020, in Windows 10. I'm using Java 8 RE and 14.1 JDK and it worked well until Eclipse upgrade to version 2020-09. After that I can't run Eclipse because it needed to use Java 11 or newer and it found only 8 version. It was because of order of environment variables of "Path":

I suppose C:\Program Files (x86)\Common Files\Oracle\Java\javapath is path to link to installed JRE exe files (in my case Java 8) and the issue was resolved by move down this link after %JAVA_HOME%, what leads to Java 14.1/bin folder.

It seems that order of environment variables affects order of searched folders while executable file is requested. Thanks for your comment or better explanation.

There is a significant problem with some of the answers posted so far: unicode() decodes from the default encoding, which is often ASCII; in fact, unicode() tries to make "sense" of the bytes it is given by converting them into characters. Thus, the following code, which is essentially what is recommended by previous answers, fails on my machine:

# -*- coding: utf-8 -*-
author = 'éric'
print '{0}'.format(unicode(author))

gives:

Traceback (most recent call last):
  File "test.py", line 3, in <module>
    print '{0}'.format(unicode(author))
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128)

The failure comes from the fact that author does not contain only ASCII bytes (i.e. with values in [0; 127]), and unicode() decodes from ASCII by default (on many machines).

A robust solution is to explicitly give the encoding used in your fields; taking UTF-8 as an example:

u'{0} in {1}'.format(unicode(self.author, 'utf-8'), unicode(self.publication, 'utf-8'))

(or without the initial u, depending on whether you want a Unicode result or a byte string).

At this point, one might want to consider having the author and publication fields be Unicode strings, instead of decoding them during formatting.

Had a similar issue while installing "Lua" in OS X using homebrew. I guess it could be useful for other users facing similar issue in homebrew.

On running the command:

$ brew install lua

The command returned an error:

Error: /usr/local/opt/lua is not a valid keg
(in general the error can be of /usr/local/opt/ is not a valid keg

FIXED it by deleting the file/directory it is referring to, i.e., deleting the "/usr/local/opt/lua" file.

root-user # rm -rf /usr/local/opt/lua

And then running the brew install command returned success.

I thought I could add a method I use in many projects.

- (NSInteger)randomValueBetween:(NSInteger)min and:(NSInteger)max {
    return (NSInteger)(min + arc4random_uniform(max - min + 1));
}

If I end up using it in many files I usually declare a macro as

#define RAND_FROM_TO(min, max) (min + arc4random_uniform(max - min + 1))

E.g.

NSInteger myInteger = RAND_FROM_TO(0, 74) // 0, 1, 2,..., 73, 74

Note: Only for iOS 4.3/OS X v10.7 (Lion) and later

tl;dr

ZonedDateTime.now(                    // Capture current moment as seen in the wall-clock time used by the people of a particular region (a time zone).
    ZoneId.of( "America/Montreal" )   // Specify desired/expected time zone. Or pass `ZoneId.systemDefault` for the JVM’s current default time zone.
)                                     // Returns a `ZonedDateTime` object.
.getMinute()                          // Extract the minute of the hour of the time-of-day from the `ZonedDateTime` object.

ZonedDateTime

To capture the current moment as seen in the wall-clock time used by the people of a particular region (a time zone), use ZonedDateTime.

A time zone is crucial in determining a date. For any given moment, the date varies around the globe by zone. For example, a few minutes after midnight in Paris France is a new day while still “yesterday” in Montréal Québec.

If no time zone is specified, the JVM implicitly applies its current default time zone. That default may change at any moment during runtime(!), so your results may vary. Better to specify your desired/expected time zone explicitly as an argument.

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = ZonedDateTime.now( z ) ;

Call any of the many getters to pull out pieces of the date-time.

int    year        = zdt.getYear() ;
int    monthNumber = zdt.getMonthValue() ;
String monthName   = zdt.getMonth().getDisplayName( TextStyle.FULL , Locale.JAPAN ) ;  // Locale determines human language and cultural norms used in localizing. Note that `Locale` has *nothing* to do with time zone.
int    dayOfMonth  = zdt.getDayOfMonth() ;
String dayOfWeek   = zdt.getDayOfWeek().getDisplayName( TextStyle.FULL , Locale.CANADA_FRENCH ) ; 
int    hour        = zdt.getHour() ;  // Extract the hour from the time-of-day.
int    minute      = zdt.getMinute() ;
int    second      = zdt.getSecond() ;
int    nano        = zdt.getNano() ;

The java.time classes resolve to nanoseconds. Your Question asked for the fraction of a second in milliseconds. Obviously, you can divide by a million to truncate nanoseconds to milliseconds, at the cost of possible data loss. Or use the TimeUnit enum for such conversion.

long millis = TimeUnit.NANOSECONDS.toMillis( zdt.getNano() ) ;

DateTimeFormatter

To produce a String to combine pieces of text, use DateTimeFormatter class. Search Stack Overflow for more info on this.

Instant

Usually best to track moments in UTC. To adjust from a zoned date-time to UTC, extract a Instant.

Instant instant = zdt.toInstant() ;

And go back again.

ZonedDateTime zdt = instant.atZone( ZoneId.of( "Africa/Tunis" ) ) ;

LocalDateTime

A couple of other Answers use the LocalDateTime class. That class in not appropriate to the purpose of tracking actual moments, specific moments on the timeline, as it intentionally lacks any concept of time zone or offset-from-UTC.

So what is LocalDateTime good for? Use LocalDateTime when you intend to apply a date & time to any locality or all localities, rather than one specific locality.

For example, Christmas this year starts at the LocalDateTime.parse( "2018-12-25T00:00:00" ). That value has no meaning until you apply a time zone (a ZoneId) to get a ZonedDateTime. Christmas happens first in Kiribati, then later in New Zealand and far east Asia. Hours later Christmas starts in India. More hour later in Africa & Europe. And still not Xmas in the Americas until several hours later. Christmas starting in any one place should be represented with ZonedDateTime. Christmas everywhere is represented with a LocalDateTime.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The getRequestURL() omits the port when it is 80 while the scheme is http, or when it is 443 while the scheme is https.

So, just use getRequestURL() if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:

StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
    requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();

This one worked for me.

<td style="border-top: none;">;

The key is you need to add border-top to the <td>

In the C language as it was documented in 1974, all structure members shared a common namespace, and the meaning of "ptr->member" was defined as adding the member's displacement to "ptr" and accessing the resulting address using the member's type. This design made it possible to use the same ptr with member names taken from different structure definitions but with the same offset; programmers used that ability for a variety of purposes.

When structure members were assigned their own namespaces, it became impossible to declare two structure members with the same displacement. Adding unions to the language made it possible to achieve the same semantics that had been available in earlier versions of the language (though the inability to have names exported to an enclosing context may have still necessitated using a find/replace to replace foo->member into foo->type1.member). What was important was not so much that the people who added unions have any particular target usage in mind, but rather that they provide a means by which programmers who had relied upon the earlier semantics, for whatever purpose, should still be able to achieve the same semantics even if they had to use a different syntax to do it.

I am using Visual Studio 2013 and Win 8.1. It was Shift + 0 (0 is my insert key) on the number pad of my laptop.

You can use java.util.Arrays:

String res = Arrays.toString(array);
System.out.println(res);

Output:

[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

The following is not a 100% guaranteed method, and should not at all be attempted for scripting. But some times it is good enough for quick interactive shell usage. A file file glob like

[abc]*

(which will match all files with names starting with a, b or c) can be negated by inserting a "^" character first, i.e.

[^abc]*

I sometimes use this for not matching the "lost+found" directory, like for instance:

mv /mnt/usbdisk/[^l]* /home/user/stuff/.

Of course if there are other files starting with l I have to process those afterwards.

    }
    var dot = count(txt, /\./, pos)

    function count(str, c, e) {
        e = e || str.length

        return n
    }
}

try this:

     Header set Access-Control-Allow-Credentials true
     Header set Access-Control-Allow-Origin "your domain"
     Header set Access-Control-Allow-Headers "X-Requested-With"
</IfModule>

It's preferable to allow a list of know trusted host.

I would like to propose this solution which is based on the first part of Dom's answer.

We first define two variables, "action" and "controller" and use them to determine the active link:

{ string controller = ViewContext.RouteData.Values["Controller"].ToString();
string action = ViewContext.RouteData.Values["Action"].ToString();}

And then:

<ul class="nav navbar-nav">
    <li class="@((controller == "Home" && action == "Index") ? "active" : "")">@Html.ActionLink("Home", "Index", "Home")</li>
    <li class="@((controller == "Home" && action == "About") ? "active" : "")">@Html.ActionLink("About", "About", "Home")</li>
    <li class="@((controller == "Home" && action == "Contact") ? "active" : "")">@Html.ActionLink("Contact", "Contact", "Home")</li>
</ul>

Now it looks nicer and no need for more complex solutions.

If you only want the filenames and also want any files that have been added (A).

svn st | grep ^[AM] | cut -c9-

Note: The first 7 columns are each one character wide followed by a space then the filename.

you can use regular expressions to identify the last comma (,) and replace it with " " as follow:

if(fieldName.endsWith(","))
{                           
fieldName = fieldName.replace(/,([^,]*)$/," ");
}

A generic answer on how to handle click events with KnockoutJS...

Not a straight up answer to the question as asked, but probably an answer to the question most Googlers landing here have: use the click binding from KnockoutJS instead of onclick. Like this:

function Item(parent, txt) {_x000D_
  var self = this;_x000D_
  _x000D_
  self.doStuff = function(data, event) {_x000D_
    console.log(data, event);_x000D_
    parent.log(parent.log() + "\n  data = " + ko.toJSON(data));_x000D_
  };_x000D_
  _x000D_
  self.doOtherStuff = function(customParam, data, event) {_x000D_
    console.log(data, event);_x000D_
    parent.log(parent.log() + "\n  data = " + ko.toJSON(data) + ", customParam = " + customParam);_x000D_
  };_x000D_
  _x000D_
  self.txt = ko.observable(txt);_x000D_
}_x000D_
_x000D_
function RootVm(items) {_x000D_
  var self = this;_x000D_
  _x000D_
  self.doParentStuff = function(data, event) {_x000D_
    console.log(data, event);_x000D_
    self.log(self.log() + "\n  data = " + ko.toJSON(data));_x000D_
  };_x000D_
  _x000D_
  self.items = ko.observableArray([_x000D_
    new Item(self, "John Doe"),_x000D_
    new Item(self, "Marcus Aurelius")_x000D_
  ]);_x000D_
  self.log = ko.observable("Started logging...");_x000D_
}_x000D_
_x000D_
ko.applyBindings(new RootVm());

.parent { background: rgba(150, 150, 200, 0.5); padding: 2px; margin: 5px; }_x000D_

**A note about the actual question...*

The actual question has one interesting bit:

// Uh oh! Modifying the DOM....
place.innerHTML = "somthing"

Don't do that! Don't modify the DOM like that when using an MVVM framework like KnockoutJS, especially not the piece of the DOM that is your own parent. If you would do this the button would disappear (if you replace your parent's innerHTML you yourself will be gone forever ever!).

Instead, modify the View Model in your handler instead, and have the View respond. For example:

function RootVm() {_x000D_
  var self = this;_x000D_
  self.buttonWasClickedOnce = ko.observable(false);_x000D_
  self.toggle = function(data, event) {_x000D_
    self.buttonWasClickedOnce(!self.buttonWasClickedOnce());_x000D_
  };_x000D_
}_x000D_
_x000D_
ko.applyBindings(new RootVm());

Put them into a list and use merge with Reduce

Reduce(function(x, y) merge(x, y, all=TRUE), list(df1, df2, df3))
#    id v1 v2 v3
# 1   1  1 NA NA
# 2  10  4 NA NA
# 3   2  3  4 NA
# 4  43  5 NA NA
# 5  73  2 NA NA
# 6  23 NA  2  1
# 7  57 NA  3 NA
# 8  62 NA  5  2
# 9   7 NA  1 NA
# 10 96 NA  6 NA

You can also use this more concise version:

Reduce(function(...) merge(..., all=TRUE), list(df1, df2, df3))

With regard to Brent.Longborough's answer (appering only on page 2 onward), perhaps you need to set the \thispagestyle{} after \begin{document}. I wonder if the letter class is setting the first page style to empty.

Actually it's quite different. DOUBLE causes rounding issues. And if you do something like 0.1 + 0.2 it gives you something like 0.30000000000000004. I personally would not trust financial data that uses floating point math. The impact may be small, but who knows. I would rather have what I know is reliable data than data that were approximated, especially when you are dealing with money values.

A couple of things:

1. Your regexes need to be anchored by separators* or you'll match partial words, as is the case now
2. You're not using the proper syntax for a non-capturing group. It's (?: not (:?

If you address the first problem, you won't need groups at all.

*That is, a blank or beginning/end of string.

As long and your input and label elements are associated by their id and for attributes, you should be able to do something like this:

$('.input').each(function() { 
   $this = $(this);
   $label = $('label[for="'+ $this.attr('id') +'"]');
   if ($label.length > 0 ) {
       //this input has a label associated with it, lets do something!
   }
});

If for is not set then the elements have no semantic relation to each other anyway, and there is no benefit to using the label tag in that instance, so hopefully you will always have that relationship defined.

You should be able to use the Clear() method.

200,300, 400, 500 are all very generic. If you want generic, 400 is OK.

422 is used by an increasing number of APIs, and is even used by Rails out of the box.

No matter which status code you pick for your API, someone will disagree. But I prefer 422 because I think of '400 + text status' as too generic. Also, you aren't taking advantage of a JSON-ready parser; in contrast, a 422 with a JSON response is very explicit, and a great deal of error information can be conveyed.

Speaking of JSON response, I tend to standardize on the Rails error response for this case, which is:

{
    "errors" :
    { 
        "arg1" : ["error msg 1", "error msg 2", ...]
        "arg2" : ["error msg 1", "error msg 2", ...]
    }
}

This format is perfect for form validation, which I consider the most complex case to support in terms of 'error reporting richness'. If your error structure is this, it will likely handle all your error reporting needs.

Here is a solution I made using the above ideas that can be used for TextBoxFor and PasswordFor:

public static class HtmlHelperEx
{
    public static MvcHtmlString TextBoxWithPlaceholderFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper,
        Expression<Func<TModel, TProperty>> expression, object htmlAttributes)
    {
        var metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
        return htmlHelper.TextBoxFor(expression, htmlAttributes.AddAttribute("placeholder", metadata.Watermark));

    }

    public static MvcHtmlString PasswordWithPlaceholderFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper,
        Expression<Func<TModel, TProperty>> expression, object htmlAttributes)
    {
        var metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
        return htmlHelper.PasswordFor(expression, htmlAttributes.AddAttribute("placeholder", metadata.Watermark));

    }
}

public static class HtmlAttributesHelper
{
    public static IDictionary<string, object> AddAttribute(this object htmlAttributes, string name, object value)
    {
        var dictionary = htmlAttributes == null ? new Dictionary<string, object>() : htmlAttributes.ToDictionary();
        if (!String.IsNullOrWhiteSpace(name) && value != null && !String.IsNullOrWhiteSpace(value.ToString()))
            dictionary.Add(name, value);
        return dictionary;
    }

    public static IDictionary<string, object> ToDictionary(this object obj)
    {
        return TypeDescriptor.GetProperties(obj)
            .Cast<PropertyDescriptor>()
            .ToDictionary(property => property.Name, property => property.GetValue(obj));
    }
}

In addition to kiran's post, there's the update helper (formerly a react addon). This can be installed with npm using npm install immutability-helper

import update from 'immutability-helper';

var abc = update(this.state.abc, {
   xyz: {$set: 'foo'}
});

this.setState({abc: abc});

This creates a new object with the updated value, and other properties stay the same. This is more useful when you need to do things like push onto an array, and set some other value at the same time. Some people use it everywhere because it provides immutability.

If you do this, you can have the following to make up for the performance of

shouldComponentUpdate: function(nextProps, nextState){
   return this.state.abc !== nextState.abc; 
   // and compare any props that might cause an update
}

All these input keyevent combinations are SO android/hardware dependent, it's a pain.

However, I finally found the combination for my old android 4.1 device :

adb shell am start -a android.intent.action.MAIN -n com.android.settings/.wifi.WifiSettings
adb shell "input keyevent KEYCODE_DPAD_LEFT;input keyevent KEYCODE_DPAD_RIGHT;input keyevent KEYCODE_DPAD_CENTER"

is_uploaded_file() is great to use, specially for checking whether it is an uploaded file or a local file (for security purposes).

However, if you want to check whether the user uploaded a file, use $_FILES['file']['error'] == UPLOAD_ERR_OK.

See the PHP manual on file upload error messages. If you just want to check for no file, use UPLOAD_ERR_NO_FILE.

Use bash builtin redirection (tldp):

cat file2 >> file1

Use javascript's execCommand('SaveAs', false, filename); functionality

Edit: No longer works. This Javascript function used to work across all browsers, but now only on IE, due to browser security considerations. It presented a "Save As" Dialog to the user who runs this function through their browser, the user presses OK and the file is saved by javascript on the server side.

Now this code is an rare antique zero day collectible.

// content is the data (a string) you'll write to file.
// filename is a string filename to write to on server side.
// This function uses iFrame as a buffer, it fills it up with your content
// and prompts the user to save it out.
function save_content_to_file(content, filename){
    var dlg = false;
    with(document){
     ir=createElement('iframe');
     ir.id='ifr';
     ir.location='about.blank';
     ir.style.display='none';
     body.appendChild(ir);
      with(getElementById('ifr').contentWindow.document){
           open("text/plain", "replace");
           charset = "utf-8";
           write(content);
           close();
           document.charset = "utf-8";
           dlg = execCommand('SaveAs', false, filename);
       }
       body.removeChild(ir);
     }
    return dlg;
}

Invoke the function like this:

msg =  "I am the president of tautology club.";
save_content_to_file(msg, "C:\\test");

Thou the above answer is widely accepted and well documented, I found some of the reason to post my answer here :-

    doNothing().when(InternalUtils.class); //This is the preferred way
                                           //to mock static void methods.
    InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());

Here, I dont understand why we are calling InternalUtils.sendEmail ourself. I will explain in my code why we don't need to do that.

mockStatic(Internalutils.class);

So, we have mocked the class which is fine. Now, lets have a look how we need to verify the sendEmail(/..../) method.

@PrepareForTest({InternalService.InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest {

    @Mock
    private InternalService.Order order;

    private InternalService internalService;

    @Before
    public void setup() {
        MockitoAnnotations.initMocks(this);
        internalService = new InternalService();
    }

    @Test
    public void processOrder() throws Exception {

        Mockito.when(order.isSuccessful()).thenReturn(true);
        PowerMockito.mockStatic(InternalService.InternalUtils.class);

        internalService.processOrder(order);

        PowerMockito.verifyStatic(times(1));
        InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());
    }

}

These two lines is where the magic is, First line tells the PowerMockito framework that it needs to verify the class it statically mocked. But which method it need to verify ?? Second line tells which method it needs to verify.

PowerMockito.verifyStatic(times(1));
InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());

This is code of my class, sendEmail api twice.

public class InternalService {

    public void processOrder(Order order) {
        if (order.isSuccessful()) {
            InternalUtils.sendEmail("", new String[1], "", "");
            InternalUtils.sendEmail("", new String[1], "", "");
        }
    }

    public static class InternalUtils{

        public static void sendEmail(String from, String[]  to, String msg, String body){

        }

    }

    public class Order{

        public boolean isSuccessful(){
            return true;
        }

    }

}

As it is calling twice you just need to change the verify(times(2))... that's all.

Using KeyGenerator would be the preferred method. As Duncan indicated, I would certainly give the key size during initialization. KeyFactory is a method that should be used for pre-existing keys.

OK, so lets get to the nitty-gritty of this. In principle AES keys can have any value. There are no "weak keys" as in (3)DES. Nor are there any bits that have a specific meaning as in (3)DES parity bits. So generating a key can be as simple as generating a byte array with random values, and creating a SecretKeySpec around it.

But there are still advantages to the method you are using: the KeyGenerator is specifically created to generate keys. This means that the code may be optimized for this generation. This could have efficiency and security benefits. It might be programmed to avoid a timing side channel attacks that would expose the key, for instance. Note that it may already be a good idea to clear any byte[] that hold key information as they may be leaked into a swap file (this may be the case anyway though).

Furthermore, as said, not all algorithms are using fully random keys. So using KeyGenerator would make it easier to switch to other algorithms. More modern ciphers will only accept fully random keys though; this is seen as a major benefit over e.g. DES.

Finally, and in my case the most important reason, it that the KeyGenerator method is the only valid way of handling AES keys within a secure token (smart card, TPM, USB token or HSM). If you create the byte[] with the SecretKeySpec then the key must come from memory. That means that the key may be put in the secure token, but that the key is exposed in memory regardless. Normally, secure tokens only work with keys that are either generated in the secure token or are injected by e.g. a smart card or a key ceremony. A KeyGenerator can be supplied with a provider so that the key is directly generated within the secure token.

As indicated in Duncan's answer: always specify the key size (and any other parameters) explicitly. Do not rely on provider defaults as this will make it unclear what your application is doing, and each provider may have its own defaults.

In rxjs 6 map operator usage has been changed now you need to Use it like this.

The $@ and $< are special macros.

Where:

$@ is the file name of the target.

$< is the name of the first dependency.

In order to make ngModel work when using AppModules (NgModule ), you have to import FormsModule in your AppModule .

Like this:

import { NgModule } from '@angular/core';
import { BrowserModule  } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';

import { AppComponent }   from './app.component';


@NgModule({
    declarations: [AppComponent],
    imports: [BrowserModule, FormsModule],
    bootstrap: [AppComponent]
})
export class AppModule {}

I think there is some confusion about the difference between MVC and Web Api. In short, for MVC you can use a login form and create a session using cookies. For Web Api there is no session. That's why you want to use the token.

You do not need a login form. The Token endpoint is all you need. Like Win described you'll send the credentials to the token endpoint where it is handled.

Here's some client side C# code to get a token:

    //using System;
    //using System.Collections.Generic;
    //using System.Net;
    //using System.Net.Http;
    //string token = GetToken("https://localhost:<port>/", userName, password);

    static string GetToken(string url, string userName, string password) {
        var pairs = new List<KeyValuePair<string, string>>
                    {
                        new KeyValuePair<string, string>( "grant_type", "password" ), 
                        new KeyValuePair<string, string>( "username", userName ), 
                        new KeyValuePair<string, string> ( "Password", password )
                    };
        var content = new FormUrlEncodedContent(pairs);
        ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
        using (var client = new HttpClient()) {
            var response = client.PostAsync(url + "Token", content).Result;
            return response.Content.ReadAsStringAsync().Result;
        }
    }

In order to use the token add it to the header of the request:

    //using System;
    //using System.Collections.Generic;
    //using System.Net;
    //using System.Net.Http;
    //var result = CallApi("https://localhost:<port>/something", token);

    static string CallApi(string url, string token) {
        ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;
        using (var client = new HttpClient()) {
            if (!string.IsNullOrWhiteSpace(token)) {
                var t = JsonConvert.DeserializeObject<Token>(token);

                client.DefaultRequestHeaders.Clear();
                client.DefaultRequestHeaders.Add("Authorization", "Bearer " + t.access_token);
            }
            var response = client.GetAsync(url).Result;
            return response.Content.ReadAsStringAsync().Result;
        }
    }

Where Token is:

//using Newtonsoft.Json;

class Token
{
    public string access_token { get; set; }
    public string token_type { get; set; }
    public int expires_in { get; set; }
    public string userName { get; set; }
    [JsonProperty(".issued")]
    public string issued { get; set; }
    [JsonProperty(".expires")]
    public string expires { get; set; }
}

Now for the server side:

In Startup.Auth.cs

        var oAuthOptions = new OAuthAuthorizationServerOptions
        {
            TokenEndpointPath = new PathString("/Token"),
            Provider = new ApplicationOAuthProvider("self"),
            AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
            // https
            AllowInsecureHttp = false
        };
        // Enable the application to use bearer tokens to authenticate users
        app.UseOAuthBearerTokens(oAuthOptions);

And in ApplicationOAuthProvider.cs the code that actually grants or denies access:

//using Microsoft.AspNet.Identity.Owin;
//using Microsoft.Owin.Security;
//using Microsoft.Owin.Security.OAuth;
//using System;
//using System.Collections.Generic;
//using System.Security.Claims;
//using System.Threading.Tasks;

public class ApplicationOAuthProvider : OAuthAuthorizationServerProvider
{
    private readonly string _publicClientId;

    public ApplicationOAuthProvider(string publicClientId)
    {
        if (publicClientId == null)
            throw new ArgumentNullException("publicClientId");

        _publicClientId = publicClientId;
    }

    public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
    {
        var userManager = context.OwinContext.GetUserManager<ApplicationUserManager>();

        var user = await userManager.FindAsync(context.UserName, context.Password);
        if (user == null)
        {
            context.SetError("invalid_grant", "The user name or password is incorrect.");
            return;
        }

        ClaimsIdentity oAuthIdentity = await user.GenerateUserIdentityAsync(userManager);
        var propertyDictionary = new Dictionary<string, string> { { "userName", user.UserName } };
        var properties = new AuthenticationProperties(propertyDictionary);

        AuthenticationTicket ticket = new AuthenticationTicket(oAuthIdentity, properties);
        // Token is validated.
        context.Validated(ticket);
    }

    public override Task TokenEndpoint(OAuthTokenEndpointContext context)
    {
        foreach (KeyValuePair<string, string> property in context.Properties.Dictionary)
        {
            context.AdditionalResponseParameters.Add(property.Key, property.Value);
        }
        return Task.FromResult<object>(null);
    }

    public override Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
    {
        // Resource owner password credentials does not provide a client ID.
        if (context.ClientId == null)
            context.Validated();

        return Task.FromResult<object>(null);
    }

    public override Task ValidateClientRedirectUri(OAuthValidateClientRedirectUriContext context)
    {
        if (context.ClientId == _publicClientId)
        {
            var expectedRootUri = new Uri(context.Request.Uri, "/");

            if (expectedRootUri.AbsoluteUri == context.RedirectUri)
                context.Validated();
        }
        return Task.FromResult<object>(null);
    }

}

As you can see there is no controller involved in retrieving the token. In fact, you can remove all MVC references if you want a Web Api only. I have simplified the server side code to make it more readable. You can add code to upgrade the security.

Make sure you use SSL only. Implement the RequireHttpsAttribute to force this.

You can use the Authorize / AllowAnonymous attributes to secure your Web Api. Additionally you can add filters (like RequireHttpsAttribute) to make your Web Api more secure. I hope this helps.

In many case you will need to add the bodyParser module in your express node app. Then in your app.use part below app.use(express.static('www')); add these 2 lines app.use(bodyParser.urlencoded({ extended: true })); app.use(bodyParser.json());

This is subjective... I find it to be a good tool.

It depends what kind of development you're doing - for EJB stuff, many folk would favour Netbeans. It also depends how much you want to spend - I assume you're talking about free IDEs?

IF both POS_History_bim_data_*.zip and POS_History_bim_data_*.zip.trg exists in  Y:\ExternalData\RSIDest\ Folder then Delete File Y:\ExternalData\RSIDest\Target_slpos_unzip_done.dat

Please check in logs if you have http.HttpWagon$__sisu1:Cannot find 'basicAuthScope' this error or warning also, if so you need to use maven 3.2.5 version, which will resolve error.

We were getting the same error - so this may be useful to some.

For us the cause was super simple. An interface change confused an end user and they were pressing the back button in the browser at a 'bad' time after a form submission (sure we should probably have used a PRG pattern, but we didn't).

We fixed the issue and the user is no longer pressing the back button. Problem solved.

You just want to set the field separator as . using the -F option and print the first field:

$ echo aaa0.bbb.ccc | awk -F'.' '{print $1}'
aaa0

Same thing but using cut:

$ echo aaa0.bbb.ccc | cut -d'.' -f1
aaa0

Or with sed:

$ echo aaa0.bbb.ccc | sed 's/[.].*//'
aaa0

Even grep:

$ echo aaa0.bbb.ccc | grep -o '^[^.]*'
aaa0

There is a subtle difference in terms of conflict management. In case of conflicts, a pull request in Github will result in a merge commit on the destination branch. In Gitlab, when a conflict is found, the modifications made will be on a merge commit on the source branch.

See https://docs.gitlab.com/ee/user/project/merge_requests/resolve_conflicts.html

"GitLab resolves conflicts by creating a merge commit in the source branch that is not automatically merged into the target branch. This allows the merge commit to be reviewed and tested before the changes are merged, preventing unintended changes entering the target branch without review or breaking the build."

Try the following

function sortCopy(arr) { 
  return arr.slice(0).sort();
}

The slice(0) expression creates a copy of the array starting at element 0.

1. sudo vim /etc/apache2/httpd.conf
2. Insert the following line at the httpd.conf: ServerName localhost
3. Just restart the Apache: sudo /etc/init.d/apache2 restart

I had to add one more line to REVOKE...

After running:

REVOKE ALL PRIVILEGES ON ALL TABLES IN SCHEMA public FROM username;
REVOKE ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public FROM username;
REVOKE ALL PRIVILEGES ON ALL FUNCTIONS IN SCHEMA public FROM username;

I was still receiving the error: username cannot be dropped because some objects depend on it DETAIL: privileges for schema public

I was missing this:

REVOKE USAGE ON SCHEMA public FROM username;

Then I was able to drop the role.

DROP USER username;

If you have indexed ID and OrderNo You can use IN: (I hate trading simplicity for obscurity, just to save some cycles):

select * from myTab where ID in(select max(ID) from myTab group by OrderNo);

If the POM missing warning is of project's self module, the reason is that you are trying to mistakenly build from a sub-module directory. You need to run the build and install command from root directory of the project.

$(document).ready(function(){ contsize();});
$(window).bind("resize",function(){contsize();});

function contsize()

var calculatecontsize = h - 70;/*if header and footer heights= 35 then total 70px*/ 
$('#content').css({"height":calculatecontsize + "px"} );
}

From the Android Developer Site link

"adjustResize"

The activity's main window is always resized to make room for the soft keyboard on screen.

"adjustPan"

The activity's main window is not resized to make room for the soft keyboard. Rather, the contents of the window are automatically panned so that the current focus is never obscured by the keyboard and users can always see what they are typing. This is generally less desirable than resizing, because the user may need to close the soft keyboard to get at and interact with obscured parts of the window.

according to your comment, use following in your activity manifest

<activity android:windowSoftInputMode="adjustResize"> </activity>

The .htaccess is either in the root-directory of your webpage or in the directory you want to protect.

Make sure to make them visible in your filesystem, because AFAIK (I'm no unix expert either) files starting with a period are invisible by default on unix-systems.

You can use the following class. Just change zero to any default value you like. The solution was tested in Python 2.7.

class cDefaultDict(dict):
    # dictionary that returns zero for missing keys
    # keys with zero values are not stored

    def __missing__(self,key):
        return 0

    def __setitem__(self, key, value):
        if value==0:
            if key in self:  # returns zero anyway, so no need to store it
                del self[key]
        else:
            dict.__setitem__(self, key, value)

I'm using

Sheet1.Range("E2", "E3000").NumberFormat = "dd/mm/yyyy hh:mm:ss"

to format a column

So I guess

Sheet1.Range("E2", "E3000").NumberFormat = "MMM dd yyyy"

would do the trick for you.

More: NumberFormat function.

I would think , in a large file scenario using a stream would be far more efficient, because memory consumption would be very small.

But your algorithm could alternate between using a stream and loading the entire thing in memory based on the file size. I wouldn't be surprised if one is only better than the other under certain criteria.

If they're all local to you, then here's the offset:

SELECT GETDATE() AS CurrentTime, GETUTCDATE() AS UTCTime

and you should be able to update all the data using:

UPDATE SomeTable
   SET DateTimeStamp = DATEADD(hh, DATEDIFF(hh, GETDATE(), GETUTCDATE()), DateTimeStamp)

Would that work, or am I missing another angle of this problem?

For anyone looking at this now, on systemd systems (in my case, specifically Ubuntu 16.04) there is another limit enforced by the cgroup pids.max parameter.

This is set to 12,288 by default, and can be overriden in /etc/systemd/logind.conf

Other advice still applies including pids_max, threads-max, max_maps_count, ulimits, etc.

In the Windows Powershell console, type

[System.IO.Directory]::GetFiles("\\.\\pipe\\")

get-childitem \\.\pipe\

This returns a list of objects. If you want the name only:

(get-childitem \\.\pipe\).FullName

(The second example \\.\pipe\ does not work in Powershell 7, but the first example does)

You can also do like this
// put value in intent

    Intent in = new Intent(MainActivity.this, Booked.class);
    in.putExtra("filter", "Booked");
    startActivity(in);

// get value from intent

    Intent intent = getIntent();
    Bundle bundle = intent.getExtras();
    String filter = bundle.getString("filter");

matrix.size according to the numpy docs returns the Number of elements in the array. Hope that helps.

Convert it back to datetime after converting to date in order to keep same datatime if needed

Change the Compile SDK version,Target SDK version to Build Tools version to 24.0.0 in build.gradle if u face issue in request Feature

>>> dict(zip(keys, values))

pattern="foo"
for _dir in *"${pattern}"*; do
    [ -d "${_dir}" ] && dir="${_dir}" && break
done
echo "${dir}"

This is better than the other shell solution provided because

• it will be faster for huge directories as the pattern is part of the glob and not checked inside the loop
• actually works as expected when there is no directory matching your pattern (then ${dir} will be empty)
• it will work in any POSIX-compliant shell since it does not rely on the =~ operator (if you need this depends on your pattern)
• it will work for directories containing newlines in their name (vs. find)

like this: put intro outside your document ready, Good discussion here: http://forum.jquery.com/topic/how-do-i-declare-a-global-variable-in-jquery @thecodeparadox is awesomely fast :P anyways!

I just talked to some Xcode engineers at WWDC and the auto discovery of iDevices is still a little buggy. Also sometimes your phone is not correctly broadcasting. Switching your device on and off can help.

There are a few workarounds/fallbacks:

You can check if your phone is broadcasting with Bonjour Browser (www.tildesoft.com). Look if your wifi address is listed under the service called '_apple-mobdev2._tcp. - 215' (you can find your wifi address here: settings > general > about > wifi address.

As a fallback you can connect to your device by manually entering the IP address (right click on your devices in the Devices window). However this IP address will be persisted, so if you change networks you'll need to reset this. That option is not available in Xcode yet, but you can do it via the terminal with the following command:

defaults read com.apple.dt.Xcode | grep IDEIDS

This will print an identifier which you need to use in the next command:

defaults delete com.apple.dt.Xcode <identifier>

Now the ip address is cleared and you can enter a new one.

The last option is to create a computer-to-computer network. This works fine, but logically you won't have internet access then.

You have to give a valid username. For example, to run query with user root you have to type the following command and then enter password when prompted:

mysql -u root -p

Once you are connected, prompt will be something like:

mysql>

Here you can write your query, after database selection, for example:

mysql> USE your_database;
mysql> SELECT * FROM your_table;

You Can do by Two ways,

1. Cloning the Remote Repo to your Local host

example: git clone https://github.com/user-name/repository.git

2. Pulling the Remote Repo to your Local host

First you have to create a git local repo by,

example: git init or git init repo-name then, git pull https://github.com/user-name/repository.git

That's all, All commits and branch in the remote repo now available in the local repository of your computer.

Happy Coding, cheers -:)

As wizzard pointed out, the correct method is,

new Date().getTime();

or under Javascript 1.5, just

Date.now();

From the documentation,

The value returned by the getTime method is the number of milliseconds since 1 January 1970 00:00:00 UTC.

If you wanted to make a time stamp without milliseconds you can use,

Math.floor(Date.now() / 1000);

I wanted to make this an answer so the correct method is more visible.

You can compare ExpExc's and Narendra Yadala's results to the method above at http://jsfiddle.net/JamesFM/bxEJd/, and verify with http://www.unixtimestamp.com/ or by running date +%s on a Unix terminal.

One more way to understand would be to think in terms of communication between processes and threads. Processes communicate with the help of coarse grained communication mechanisms like sockets, signal handlers, shared memory, semaphores and files. Threads, on the other hand, have access to shared memory space that belongs to a process, which allows them to apply finer grain communication mechanisms.

From the documentation

class typing.Union

Union type; Union[X, Y] means either X or Y.

Hence the proper way to represent more than one return data type is

from typing import Union


def foo(client_id: str) -> Union[list,bool]

But do note that typing is not enforced. Python continues to remain a dynamically-typed language. The annotation syntax has been developed to help during the development of the code prior to being released into production. As PEP 484 states, "no type checking happens at runtime."

>>> def foo(a:str) -> list:
...     return("Works")
... 
>>> foo(1)
'Works'

As you can see I am passing a int value and returning a str. However the __annotations__ will be set to the respective values.

>>> foo.__annotations__ 
{'return': <class 'list'>, 'a': <class 'str'>}

Please Go through PEP 483 for more about Type hints. Also see What are Type hints in Python 3.5?

Kindly note that this is available only for Python 3.5 and upwards. This is mentioned clearly in PEP 484.

Easy:

1. Create interface class, where String output is optional, or can be whatever variables you want to return.

   public interface AsyncResponse {
       void processFinish(String output);
   }
   

2. Go to your AsyncTask class, and declare interface AsyncResponse as a field :

   public class MyAsyncTask extends AsyncTask<Void, Void, String> {
     public AsyncResponse delegate = null;
   
       @Override
       protected void onPostExecute(String result) {
         delegate.processFinish(result);
       }
    }
   

3. In your main Activity you need to implements interface AsyncResponse.

   public class MainActivity implements AsyncResponse{
     MyAsyncTask asyncTask =new MyAsyncTask();
   
     @Override
     public void onCreate(Bundle savedInstanceState) {
   
        //this to set delegate/listener back to this class
        asyncTask.delegate = this;
   
        //execute the async task 
        asyncTask.execute();
     }
   
     //this override the implemented method from asyncTask
     @Override
     void processFinish(String output){
        //Here you will receive the result fired from async class 
        //of onPostExecute(result) method.
      }
    }
   

UPDATE

I didn't know this is such a favourite to many of you. So here's the simple and convenience way to use interface.

still using same interface. FYI, you may combine this into AsyncTask class.

in AsyncTask class :

public class MyAsyncTask extends AsyncTask<Void, Void, String> {

  // you may separate this or combined to caller class.
  public interface AsyncResponse {
        void processFinish(String output);
  }

  public AsyncResponse delegate = null;

    public MyAsyncTask(AsyncResponse delegate){
        this.delegate = delegate;
    }

    @Override
    protected void onPostExecute(String result) {
      delegate.processFinish(result);
    }
}

do this in your Activity class

public class MainActivity extends Activity {

   MyAsyncTask asyncTask = new MyAsyncTask(new AsyncResponse(){

     @Override
     void processFinish(String output){
     //Here you will receive the result fired from async class 
     //of onPostExecute(result) method.
     }
  }).execute();

 }

Or, implementing the interface on the Activity again

public class MainActivity extends Activity 
    implements AsyncResponse{

    @Override
    public void onCreate(Bundle savedInstanceState) {

        //execute the async task 
        new MyAsyncTask(this).execute();
    }

    //this override the implemented method from AsyncResponse
    @Override
    void processFinish(String output){
        //Here you will receive the result fired from async class 
        //of onPostExecute(result) method.
    }
}

As you can see 2 solutions above, the first and third one, it needs to create method processFinish, the other one, the method is inside the caller parameter. The third is more neat because there is no nested anonymous class. Hope this helps

Tip: Change String output, String response, and String result to different matching types in order to get different objects.

Put it in .gitignore. But from the gitignore(5) man page:

  ·   If the pattern does not contain a slash /, git treats it as a shell
       glob pattern and checks for a match against the pathname relative
       to the location of the .gitignore file (relative to the toplevel of
       the work tree if not from a .gitignore file).

  ·   Otherwise, git treats the pattern as a shell glob suitable for
       consumption by fnmatch(3) with the FNM_PATHNAME flag: wildcards in
       the pattern will not match a / in the pathname. For example,
       "Documentation/*.html" matches "Documentation/git.html" but not
       "Documentation/ppc/ppc.html" or
       "tools/perf/Documentation/perf.html".

So, either specify the full path to the appropriate *.pyc entry, or put it in a .gitignore file in any of the directories leading from the repository root (inclusive).

Yes you can do so and I have created a library for the same.
This allows you to connect up-to four devices to the main server device creating different channels for each client and running interactions on different threads.
To use this library simple add compile com.mdg.androble:library:0.1.2 in dependency section of your build.gradle .

I've found this script example useful (from http://www.mrexcel.com/forum/excel-questions/898899-json-api-excel.html#post4332075 ):

Sub getData()

    Dim Movie As Object
    Dim scriptControl As Object

    Set scriptControl = CreateObject("MSScriptControl.ScriptControl")
    scriptControl.Language = "JScript"

    With CreateObject("MSXML2.XMLHTTP")
        .Open "GET", "http://www.omdbapi.com/?t=frozen&y=&plot=short&r=json", False
        .send
        Set Movie = scriptControl.Eval("(" + .responsetext + ")")
        .abort
        With Sheets(2)
            .Cells(1, 1).Value = Movie.Title
            .Cells(1, 2).Value = Movie.Year
            .Cells(1, 3).Value = Movie.Rated
            .Cells(1, 4).Value = Movie.Released
            .Cells(1, 5).Value = Movie.Runtime
            .Cells(1, 6).Value = Movie.Director
            .Cells(1, 7).Value = Movie.Writer
            .Cells(1, 8).Value = Movie.Actors
            .Cells(1, 9).Value = Movie.Plot
            .Cells(1, 10).Value = Movie.Language
            .Cells(1, 11).Value = Movie.Country
            .Cells(1, 12).Value = Movie.imdbRating
        End With
    End With

End Sub

Try either

• sudo apt-get install php-zip or
• sudo apt-get install php5.6-zip

Then, you might have to restart your web server.

• sudo service apache2 restart or
• sudo service nginx restart

If you are installing on centos or fedora OS then use yum in place of apt-get. example:-

sudo yum install php-zip or sudo yum install php5.6-zip and sudo service httpd restart

You have two span6 divs within your row so that will take up the whole 12 spans that a row is made up of.

Adding pull-right to the second span6 div isn't going to do anything to it as it's already sitting to the right.

If you mean you want to have the text in the second span6 div aligned to the right then simple add a new class to that div and give it the text-align: right value e.g.

.myclass {
    text-align: right;
}

UPDATE:

EricFreese pointed out that in the 2.3 release of Bootstrap (last week) they've added text-align utility classes that you can use:

• .text-left
• .text-center
• .text-right

Actually there are tons of IoC frameworks. It seems like every programmer tries to write one at some point of their career. Maybe not to publish it, but to learn the inner workings.

I personally prefer autofac since it's quite flexible and have syntax that suits me (although I really hate that all register methods are extension methods).

Some other frameworks:

• https://simpleinjector.org/
• http://microioc.codeplex.com/
• http://munq.codeplex.com/
• http://funq.codeplex.com/

I don't know if it is help. Create an AVD for a tablet-type device: Set the target to "Android 3.0" and the skin to "WXGA" (the default skin). You can check this site. http://developer.android.com/guide/practices/optimizing-for-3.0.html

The process handle will be signaled if it exits.

So the following will work (error handling removed for brevity):

BOOL IsProcessRunning(DWORD pid)
{
    HANDLE process = OpenProcess(SYNCHRONIZE, FALSE, pid);
    DWORD ret = WaitForSingleObject(process, 0);
    CloseHandle(process);
    return ret == WAIT_TIMEOUT;
}

Note that process ID's can be recycled - it's better to cache the handle that is returned from the CreateProcess call.

You can also use the threadpool API's (SetThreadpoolWait on Vista+, RegisterWaitForSingleObject on older platforms) to receive a callback when the process exits.

EDIT: I missed the "want to do something to the process" part of the original question. You can use this technique if it is ok to have potentially stale data for some small window or if you want to fail an operation without even attempting it. You will still have to handle the case where the action fails because the process has exited.

I had this error coming up between 2 Linux boxes. Easily solved by installing RSYNC on the remote box as well as the local one.

I'm going to put this in here more for completeness than direct relevance to the OP. I spent nearly a day debugging an HttpClient request, wondering why I was never getting back a response.

Finally found that I had forgotten to await the async call further down the call stack.

Feels about as good as missing a semicolon.

Give this a try...

I use such method to do this

        "HTTP_FORWARDED_FOR",
        "HTTP_FORWARDED",
        "HTTP_VIA",
        "REMOTE_ADDR"
    };

    public static String getClientIpAddressIfServletRequestExist() {

        if (RequestContextHolder.getRequestAttributes() == null) {
            return "0.0.0.0";
        }

        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
        for (String header: IP_HEADER_CANDIDATES) {
            String ipList = request.getHeader(header);
            if (ipList != null && ipList.length() != 0 && !"unknown".equalsIgnoreCase(ipList)) {
                String ip = ipList.split(",")[0];
                return ip;
            }
        }

        return request.getRemoteAddr();
    }
}

you can use wc to count the number of characters in the file wc -m filename.txt. Hope that help.

The insert or replace query would insert a new record if id=1 does not already exist.

The update query would only oudate id=1 if it aready exist, it would not create a new record if it didn't exist.

To do (@Vladimir)'s answer is Swift:

var buttonPosition = sender.convertPoint(CGPointZero, toView: self.tableView)
var indexPath = self.tableView.indexPathForRowAtPoint(buttonPosition)!

Although checking for indexPath != nil gives me the finger..."NSIndexPath is not a subtype of NSString"

Quite simple:

$input = array(
  array(
    'tag_name' => 'google'
  ),
  array(
    'tag_name' => 'technology'
  )
);

echo implode(', ', array_map(function ($entry) {
  return $entry['tag_name'];
}, $input));

http://3v4l.org/ltBZ0

and new in php v5.5.0, array_column:

echo implode(', ', array_column($input, 'tag_name'));

public String decodeString(String URL)
    {

    String urlString="";
    try {
        urlString = URLDecoder.decode(URL,"UTF-8");
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block

        }

        return urlString;

    }

Try mylist[0][0]. This should return the first character.

q  = [1, 2, 3, 4, 1, 2, 5, 1, 2, 3, 4, 5]
vm = [-1, -1, -1, -1,1,2,3,1]

p = []
for v in vm:
    if v in q:
        p.append(q.index(v))
    else:
        p.append(99999)

print p
p = [q.index(v) if v in q else 99999 for v in vm]
print p

Output:

[99999, 99999, 99999, 99999, 0, 1, 2, 0]
[99999, 99999, 99999, 99999, 0, 1, 2, 0]

Instead of using append() in the list comprehension you can reference the p as direct output, and use q.index(v) and 99999 in the LC.

Not sure if this is intentional but note that q.index(v) will find just the first occurrence of v, even tho you have several in q. If you want to get the index of all v in q, consider using a enumerator and a list of already visited indexes

Something in those lines(pseudo-code):

visited = []
for i, v in enumerator(vm):
   if i not in visited:
       p.append(q.index(v))
   else:
       p.append(q.index(v,max(visited))) # this line should only check for v in q after the index of max(visited)
   visited.append(i)

This works like a charm, fast and accurate:

function replace_string_in_file($filename, $string_to_replace, $replace_with){
    $content=file_get_contents($filename);
    $content_chunks=explode($string_to_replace, $content);
    $content=implode($replace_with, $content_chunks);
    file_put_contents($filename, $content);
}

Usage:

$filename="users/data/letter.txt";
$string_to_replace="US$";
$replace_with="Yuan";
replace_string_in_file($filename, $string_to_replace, $replace_with);

// never forget about EXPLODE when it comes about string parsing // it's a powerful and fast tool

Before 5.0.0-beta.6

let httpParams = new HttpParams();
Object.keys(data).forEach(function (key) {
     httpParams = httpParams.append(key, data[key]);
});

Since 5.0.0-beta.6

Since 5.0.0-beta.6 (2017-09-03) they added new feature (accept object map for HttpClient headers & params)

Going forward the object can be passed directly instead of HttpParams.

getCountries(data: any) {
    // We don't need any more these lines
    // let httpParams = new HttpParams();
    // Object.keys(data).forEach(function (key) {
    //     httpParams = httpParams.append(key, data[key]);
    // });

    return this.httpClient.get("/api/countries", {params: data})
}

I think that the fastest way to do it by hand is following code. You can compare it's speed to memset function, but it shouldn't be slower.

(change type of ptr and ptr1 pointers if your array type is different then int)

#define SIZE_X 100
#define SIZE_Y 100

int *ptr, *ptr1;
ptr = &array[0][0];
ptr1 = ptr + SIZE_X*SIZE_Y*sizeof(array[0][0]);

while(ptr < ptr1)
{
    *ptr++ = 0;
}

I know I'm not answering exactly what you want, but I am wondering if you're asking the right question.

Why don't you use either:

1. windows service
2. create a new thread and run your process on that

Those sound like better options if all you want is to run a process.

Once you have a JArray you can treat it just like any other Enumerable object, and using linq you can access them, check them, verify them, and select them.

var str = @"[1, 2, 3]";
var jArray = JArray.Parse(str);
Console.WriteLine(String.Join("-", jArray.Where(i => (int)i > 1).Select(i => i.ToString())));

OneTouch deployment will do all the detection and installation of pre-requisites. It's probably best to go with a pre-made solution than trying to roll your own. Trying to roll your own may lead to problems because whatever thing you key on may change with a hotfix or service pack. Likely Microsoft has some heuristic for determining what version is running.

Use urllib2. For more specifics, check out this example from doc.python.org:

Here's a snippet from the tutorial that may help

import urllib2

req = urllib2.Request('ftp://example.com')
response = urllib2.urlopen(req)
the_page = response.read()

You could try this:

string input = "lala.bla";
output = input.Split('.').Last();

You say you have a database on PhpMyAdmin, so you are using MySQL. PHP provides functions for connecting to a MySQL database.

$connection = mysql_connect('localhost', 'root', ''); //The Blank string is the password
mysql_select_db('hrmwaitrose');

$query = "SELECT * FROM employee"; //You don't need a ; like you do in SQL
$result = mysql_query($query);

echo "<table>"; // start a table tag in the HTML

while($row = mysql_fetch_array($result)){   //Creates a loop to loop through results
echo "<tr><td>" . $row['name'] . "</td><td>" . $row['age'] . "</td></tr>";  //$row['index'] the index here is a field name
}

echo "</table>"; //Close the table in HTML

mysql_close(); //Make sure to close out the database connection

In the while loop (which runs every time we encounter a result row), we echo which creates a new table row. I also add a to contain the fields.

This is a very basic template. You see the other answers using mysqli_connect instead of mysql_connect. mysqli stands for mysql improved. It offers a better range of features. You notice it is also a little bit more complex. It depends on what you need.

Use a font-awesome icon as the default icon of your navbar.

<span class="navbar-toggler-icon">   
    <i class="fas fa-bars" style="color:#fff; font-size:28px;"></i>
</span>

Or try this on old font-awesome versions:

<span class="navbar-toggler-icon">   
    <i class="fa fa-navicon" style="color:#fff; font-size:28px;"></i>
</span>

If a DLL is written in one of the .NET languages and if you only want to view what functions, there is a reference to this DLL in the project.

Then doubleclick the DLL in the references folder and then you will see what functions it has in the OBJECT EXPLORER window

If you would like to view the source code of that DLL file you can use a decompiler application such as .NET reflector. hope this helps you.

Having effects on append won't work because the content the browser displays is updated as soon as the div is appended. So, to combine Mark B's and Steerpike's answers:

Style the div you're appending as hidden before you actually append it. You can do it with inline or external CSS script, or just create the div as

<div id="new_div" style="display: none;"> ... </div>

Then you can chain effects to your append (demo):

$('#new_div').appendTo('#original_div').show('slow');

Or (demo):

var $new = $('#new_div');
$('#original_div').append($new);
$new.show('slow');

(Expanding upon ????'s answer)

Style the canvas to fill the body. When rendering to the canvas take its size into account.

http://jsfiddle.net/mqFdk/356/

<!DOCTYPE html>
<html>
<head>
    <title>aj</title>
</head>
<body>

    <canvas id="c"></canvas>

</body>
</html>

CSS:

body { 
       margin: 0; 
       padding: 0
     }
#c { 
     position: absolute; 
     width: 100%; 
     height: 100%; 
     overflow: hidden
   }

Javascript:

function redraw() {
    var cc = c.getContext("2d");
    c.width = c.clientWidth;
    c.height = c.clientHeight;
    cc.scale(c.width, c.height);

    // Draw a circle filling the canvas.
    cc.beginPath();
    cc.arc(0.5, 0.5, .5, 0, 2*Math.PI);
    cc.fill();
}

// update on any window size change.
window.addEventListener("resize", redraw);

// first draw
redraw();

Check box-sizing css property of your td elements. I had problem with css template which sets it to border-box value. You need set box-sizing: content-box.

Define an extension:

extension Ex on double {
  double toPrecision(int n) => double.parse(toStringAsFixed(n));
}

Usage:

void main() {
  double d = 2.3456789;
  double d1 = d.toPrecision(1); // 2.3
  double d2 = d.toPrecision(2); // 2.35
  double d3 = d.toPrecision(3); // 2.345
}

Your code is correct. Kindly mark small correction.

#rightcolumn {
     width: 750px;
     background-color: #777;
     display: block;
     **float: left;(wrong)**
     **float: right; (corrected)**
     border: 1px solid white;
}

Now there is special method - get_fields()

    >>> from django.contrib.auth.models import User
    >>> User._meta.get_fields()

It accepts two parameters that can be used to control which fields are returned:

• include_parents

  True by default. Recursively includes fields defined on parent classes. If set to False, get_fields() will only search for fields declared directly on the current model. Fields from models that directly inherit from abstract models or proxy classes are considered to be local, not on the parent.

• include_hidden

  False by default. If set to True, get_fields() will include fields that are used to back other field’s functionality. This will also include any fields that have a related_name (such as ManyToManyField, or ForeignKey) that start with a “+”

If the size of the string is fixed, you might find easier to use an array of chars. If you have to do this a lot, it will be a tiny bit faster too.

char[] chars = new char[3];
chars[0] = 'i';
chars[1] = 'c';
chars[2] = 'e';
return new String(chars);

Also, I noticed in your original question, you use the Char class. If your chars are not nullable, it is better to use the lowercase char type.

Per the iterated solutions via comments in the selected answer...

In Python 3:

max(stats.keys(), key=(lambda k: stats[k]))

In Python 2:

max(stats.iterkeys(), key=(lambda k: stats[k]))

As suggested by Rodja, prior to 4.0 there isn't a direct way to center the text with the drawable. And indeed setting a padding_left value does move the drawable away from the border. Therefore my suggestion is that on runtime you calculate exactly how many pixels from the left border your drawable needs to be and then pass it using setPadding Your calculation may be something like

int paddingLeft = (button.getWidth() - drawableWidth - textWidth) / 2;

The width of your drawable's is fixed and you can look it up and you can also calculate or guess the text width.

Finally, you would need to multiple the padding value by the screen density, which you can do using DisplayMetrics

The following worked for me:

Short answer

Run the following via command line (cmd):

TlbImp.exe cvextern.dll        //where cvextern.dll is your dll you want to fix.

And a valid dll will be created for you.

Longer answer

• Open cmd

• Find TlbImp.exe. Probably located in C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin. If you can't find it go to your root folder (C:\ or D:) and run:

  dir tlbimp.exe /s              //this will locate the file.
  

• Run tlbimp.exe and put your dll behind it. Example: If your dll is cvextern.dll. You can run:

  TlbImp.exe cvextern.dll
  

• A new dll has been created in the same folder of tlbimp.exe. You can use that as reference in your project.

I'm guessing you get the error on accessing audioSounds and minTime, right?

The problem is you can't access instance members from static methods. What this means is that, a static method is a method that exists only once and can be used by all other objects (if its access modifier permits it).

Instance members, on the other hand, are created for every instance of the object. So if you create ten instances, how would the runtime know out of all these instances, which audioSounds list it should access?

Like others said, make your audioSounds and minTime static, or you could make your method an instance method, if your design permits it.

Its absolutely possible only when you set layer.masksToBounds = true and do you rest stuff.

Found a solution that doesnt requires to remember and retype the custom datetime format yyyy-mm-dd hh:mm:ss.000

• On a new cell, write either =NOW() or any valid date+time like 5/30/2017 17:35: It will display correctly in your language, e.g. 5/30/2017 5:35:00 PM
• Select the cell, click on the Format Painter icon (the paint brush)
• Now click on the row header of the column that you want to apply the format.

This will copy a proper datetime format to the whole column, making it display correctly.

The new way to do with c++20 is using format.

#include <format>

auto var = std::format("sometext {} sometext {}", somevar, somevar);

starts with file:/// and ends with filename should work:

<img src="file:///C:/Users/91860/Desktop/snow.jpg" alt="Snow" style="width:100%;">

This is my first post on SO, so I don't have enough reputation to comment the accepted answer, but I had to modify the code to the following:

export function focusNextElement () {
  //add all elements we want to include in our selection
  const focussableElements = 
    'a:not([disabled]), button:not([disabled]), input[type=text]:not([disabled])'
  if (document.activeElement && document.activeElement.form) {
      var focussable = Array.prototype.filter.call(
        document.activeElement.form.querySelectorAll(focussableElements),
      function (element) {
          // if element has tabindex = -1, it is not focussable
          if ( element.hasAttribute('tabindex') && element.tabIndex === -1 ){
            return false
          }
          //check for visibility while always include the current activeElement 
          return (element.offsetWidth > 0 || element.offsetHeight > 0 || 
            element === document.activeElement)
      });
      console.log(focussable)
      var index = focussable.indexOf(document.activeElement);
      if(index > -1) {
         var nextElement = focussable[index + 1] || focussable[0];
         console.log(nextElement)
         nextElement.focus()
      }                    
  }
}

The changing of var to constant is non-critical. The main change is that we get rid of the selector that checks tabindex != "-1". Then later, if the element has the attribute tabindex AND it is set to "-1", we do NOT consider it focussable.

The reason I needed to change this was because when adding tabindex="-1" to an <input>, this element was still considered focussable because it matches the "input[type=text]:not([disabled])" selector. My change is equivalent to "if we are a non-disabled text input, and we have a tabIndex attribute, and the value of that attribute is -1, then we should not be considered focussable.

I believe that when the author of the accepted answer edited their answer to account for the tabIndex attribute, they did not do so correctly. Please let me know if this is not the case

Hope this makes sense, Check the CPU and Memory utilization and put some threshold value. If the threshold value is crossed,don't allow to create new thread else allow...

Quite a few applications seem to implement Steganography on JPEG, so it's feasible:

I liked qiao's first answer very much! The only thing missing here is to mark the vertexes as visited.

Why we need to do it?
Lets imagine that there is another node number 13 connected from node 11. Now our goal is to find node 13.
After a little bit of a run the queue will look like this:

[[1, 2, 6], [1, 3, 10], [1, 4, 7], [1, 4, 8], [1, 2, 5, 9], [1, 2, 5, 10]]

Note that there are TWO paths with node number 10 at the end.
Which means that the paths from node number 10 will be checked twice. In this case it doesn't look so bad because node number 10 doesn't have any children.. But it could be really bad (even here we will check that node twice for no reason..)
Node number 13 isn't in those paths so the program won't return before reaching to the second path with node number 10 at the end..And we will recheck it..

All we are missing is a set to mark the visited nodes and not to check them again..
This is qiao's code after the modification:

graph = {
    1: [2, 3, 4],
    2: [5, 6],
    3: [10],
    4: [7, 8],
    5: [9, 10],
    7: [11, 12],
    11: [13]
}


def bfs(graph_to_search, start, end):
    queue = [[start]]
    visited = set()

    while queue:
        # Gets the first path in the queue
        path = queue.pop(0)

        # Gets the last node in the path
        vertex = path[-1]

        # Checks if we got to the end
        if vertex == end:
            return path
        # We check if the current node is already in the visited nodes set in order not to recheck it
        elif vertex not in visited:
            # enumerate all adjacent nodes, construct a new path and push it into the queue
            for current_neighbour in graph_to_search.get(vertex, []):
                new_path = list(path)
                new_path.append(current_neighbour)
                queue.append(new_path)

            # Mark the vertex as visited
            visited.add(vertex)


print bfs(graph, 1, 13)

The output of the program will be:

[1, 4, 7, 11, 13]

Without the unneccecery rechecks..

I think you can adapt the function to substract the two timestamps:

return  EXTRACT(MINUTE FROM 
  TO_TIMESTAMP(to_char(p_date1,'DD-MON-YYYY HH:MI:SS'),'DD-MON-YYYY HH24:MI:SS')
-
  TO_TIMESTAMP(to_char(p_date2,'DD-MON-YYYY HH:MI:SS'),'DD-MON-YYYY HH24:MI:SS')
);

I think you could simplify it by just using CAST(p_date as TIMESTAMP).

return  EXTRACT(MINUTE FROM cast(p_date1 as TIMESTAMP) - cast(p_date2 as TIMESTAMP));

Remember dates and timestamps are big ugly numbers inside Oracle, not what we see in the screen; we don't need to tell him how to read them. Also remember timestamps can have a timezone defined; not in this case.

It is possible to enable/disable wifi on pre Android 10 devices using the following code:

WifiManager wifiManager = 
(WifiManager)this.context.getSystemService(Context.WIFI_SERVICE);

wifiManager.setWifiEnabled(status);

But note that it is not possible to do this anymore on Android 10 and probably going ahead as well.

Use the HAVING clause and GROUP By the fields that make the row unique

The below will find

all users that have more than one payment per day with the same account number

SELECT 
 user_id ,
 COUNT(*) count
FROM 
 PAYMENT
GROUP BY
 account,
 user_id ,
 date
HAVING
COUNT(*) > 1

Update If you want to only include those that have a distinct ZIP you can get a distinct set first and then perform you HAVING/GROUP BY

 SELECT 
    user_id,
    account_no , 
    date,
        COUNT(*)
 FROM
    (SELECT DISTINCT
            user_id,
            account_no , 
            zip, 
            date
         FROM
            payment 
    
        ) 
        payment
 GROUP BY
    
    user_id,
    account_no , 
    
    date
HAVING COUNT(*) > 1

Method can not return anonymous type. It has to be same as the type defined in method return type. Check the signature of GetProjectForCombo and see what return type you have specified.

Create a class ProjectInfo with required properties and then in new expression create object of ProjectInfo type.

class ProjectInfo
{
   public string Name {get; set; }
   public long Id {get; set; }
}

public List<ProjectInfo> GetProjectForCombo()
{
    using (MyDataContext db = new MyDataContext (DBHelper.GetConnectionString()))
    {
        var query = from pro in db.Projects
                    select new ProjectInfo(){ Name = pro.ProjectName, Id = pro.ProjectId };

        return query.ToList();
    }
}

Following Jordan's advice (which should work actually), try to set the UIImageView to be visible:

 [imageView setHidden: NO];

and also - don't forget to attach it to the main UIView:

[mainView addSubview: imageView];

and to bring to the front:

[mainView bringSubviewToFront: imageView];

Hope combining all these steps will help you solve the mystery.

If your DIV tag is immediately followed by the IMG tag, you can also use:

$(this).next();

This is my favorite solution for SQL 2008 , which puts the results into a "TEST" temp table that I can use to sort and get the results that I need :

SET NOCOUNT ON 
DBCC UPDATEUSAGE(0) 
DROP TABLE #t;
CREATE TABLE #t 
( 
[name] NVARCHAR(128),
[rows] CHAR(11),
reserved VARCHAR(18), 
data VARCHAR(18), 
index_size VARCHAR(18),
unused VARCHAR(18)
) ;
INSERT #t EXEC sp_msForEachTable 'EXEC sp_spaceused ''?''' 
SELECT * INTO TEST FROM #t;
DROP TABLE #t;
SELECT  name, [rows], reserved, data, index_size, unused FROM TEST \
WHERE ([rows] > 0) AND (name LIKE 'XXX%')

I can across this question because I was looking to implement a simple CloneObject method for arbitrary class (with a default constructor)

With generic method you can require that the type implements New().

Public Function CloneObject(Of T As New)(ByVal src As T) As T
    Dim result As T = Nothing
    Dim cloneable = TryCast(src, ICloneable)
    If cloneable IsNot Nothing Then
        result = cloneable.Clone()
    Else
        result = New T
        CopySimpleProperties(src, result, Nothing, "clone")
    End If
    Return result
End Function

With non-generic assume the type has a default constructor and catch an exception if it doesn't.

Public Function CloneObject(ByVal src As Object) As Object
    Dim result As Object = Nothing
    Dim cloneable As ICloneable
    Try
        cloneable = TryCast(src, ICloneable)
        If cloneable IsNot Nothing Then
            result = cloneable.Clone()
        Else
            result = Activator.CreateInstance(src.GetType())
            CopySimpleProperties(src, result, Nothing, "clone")
        End If
    Catch ex As Exception
        Trace.WriteLine("!!! CloneObject(): " & ex.Message)
    End Try
    Return result
End Function

I was trying to use aws-vault which uses pass and gnugp2 (gpg2). I'm on Ubuntu 20.04 running in WSL2.

I tried all the solutions above, and eventually, I had to do one more thing -

$ rm ~/.gnupg/S.*                    # remove cache
$ gpg-connect-agent reloadagent /bye # restart gpg agent
$ export GPG_TTY=$(tty)              # prompt for password
# ^ This last line should be added to your ~/.bashrc file

The source of this solution is from some blog-post in Japanese, luckily there's Google Translate :)

Twitter Bootstrap assigns the active class to the li element that represents the active tab:

$("ul#sampleTabs li.active")

An alternative is to bind the shown event of each tab, and save the active tab:

var activeTab = null;
$('a[data-toggle="tab"]').on('shown', function (e) {
  activeTab = e.target;
})

It's also interesting to note that you can use
EXPLAIN table_name which is synonymous with DESCRIBE table_name and SHOW COLUMNS FROM table_name although EXPLAIN is more commonly used to obtain information about the query execution plan.

This question has been asked before. Please see this question.

Using the accepted answer and adapting it to your problem you get:

SELECT tt.*
FROM myTable tt
INNER JOIN
    (SELECT ID, MAX(Date) AS MaxDateTime
    FROM myTable
    GROUP BY ID) groupedtt 
ON tt.ID = groupedtt.ID 
AND tt.Date = groupedtt.MaxDateTime

This worked for me on Chromium. The % for translate is in reference to the size of the bounding box of the element it is applied to so it perfectly gets the element to the lower right edge while not having to switch which property is used to specify it's location.

topleft {
  top: 0%;
  left: 0%;
}
bottomright {
  top: 100%;
  left: 100%;
  -webkit-transform: translate(-100%,-100%);
}

I got this error when I tried assigning a component property to a state property during instantiation

export default {
 props: ['value1'],
 data() {
  return {
   value2: this.value1 // throws the error
   }
  }, 
 created(){
  this.value2 = this.value1 // safe
 }
}

Assuming that the list of files is in the file 1.txt, then do:

xargs rm -r <1.txt

The -r option causes recursion into any directories named in 1.txt.

If any files are read-only, use the -f option to force the deletion:

xargs rm -rf <1.txt

Be cautious with input to any tool that does programmatic deletions. Make certain that the files named in the input file are really to be deleted. Be especially careful about seemingly simple typos. For example, if you enter a space between a file and its suffix, it will appear to be two separate file names:

file .txt

is actually two separate files: file and .txt.

This may not seem so dangerous, but if the typo is something like this:

myoldfiles *

Then instead of deleting all files that begin with myoldfiles, you'll end up deleting myoldfiles and all non-dot-files and directories in the current directory. Probably not what you wanted.

One difference observed (Python27):

os.environ raises an exception if the environmental variable does not exist. os.getenv does not raise an exception, but returns None

I have solved it by discarding my local amended commit and adding the new changes on top:

# Rewind to commit before conflicting
git reset --soft HEAD~1

# Pull the remote version
git pull

# Add the new commit on top
git add ...
git commit
git push

There's no need for bind(this) when you are using arrow functions:

  setTimeout( ()=> {
    // some code
   }, 500)

Hope it will help.

You need to scp something somewhere. You have scp ./styles/, so you're saying secure copy ./styles/, but not where to copy it to.

Generally, if you want to download, it will go:

# download: remote -> local
scp user@remote_host:remote_file local_file 

where local_file might actually be a directory to put the file you're copying in. To upload, it's the opposite:

# upload: local -> remote
scp local_file user@remote_host:remote_file

If you want to copy a whole directory, you will need -r. Think of scp as like cp, except you can specify a file with user@remote_host:file as well as just local files.

Edit: As noted in a comment, if the usernames on the local and remote hosts are the same, then the user can be omitted when specifying a remote file.

This is an old post but maybe this could help people to complete the CORS problem. To complete the basic authorization problem you should avoid authorization for OPTIONS requests in your server. This is an Apache configuration example. Just add something like this in your VirtualHost or Location.

<LimitExcept OPTIONS>
    AuthType Basic
    AuthName <AUTH_NAME>
    Require valid-user
    AuthUserFile <FILE_PATH>
</LimitExcept>

The best one that I found is http://www.favicomatic.com/ I say best because it gave me the crispest favicon, and required no editing after their transformation. It will generate favicons at 16x16 and 32x32 and to quote them "Every damn size, sir!" Also, their site looks cool and is easy to use.

They also generate the html that you need to use for the files they generate.

I looked at the first 20 or so google results, and this was by far the best.

Although this question has an accepted answer but I think this is a much cleaner way to achieve the desired output

<select required>
<option value="">Select</option>
<option>English</option>
<option>Spanish</option>
</select>

The required attribute in makes it mandatory to select an option from the list.

value="" inside the option tag combined with the required attribute in select tag makes selection of 'Select' option not permissible, thus achieving the required output

ehh, its not a bug as one person mentioned. that is the expected behavior as the number of days in a month is often different. The easiest way to get the previous month using strtotime would probably be to use -1 month from the first of this month.

$date_string = date('Y-m', strtotime('-1 month', strtotime(date('Y-m-01'))));

Well; this works as well:

home = "$System.env.HOME"

It's not clear what you're aiming for.

An enum is implictly final, with a private constructors, all its values are of the same type or a sub-type, you can obtain all its values using values(), gets its name() or ordinal() value or you can look up an enum by number or name.

You can also define subclasses (even though notionally final, something you can't do any other way)

I solved the same error, by adding "zizaco/entrust": "*" instead of the "zizaco/entrust": "~1.2".

I usually do this the following way:

def set_if_not_exists(obj,attr,value):
 if not hasattr(obj,attr): setattr(obj,attr,value)

You can also extract outside the return block:

render: function() {
    var rows = [];
    for (var i = 0; i < numrows; i++) {
        rows.push(<ObjectRow key={i}/>);
    } 

    return (<tbody>{rows}</tbody>);
}

So I ran into this today.

Was attempting to validate an uploaded CSV file's MIME type by looking at $_FILES['upload_file']['type'], but for certain users on various browsers (and not necessarily the same browsers between said users; for instance it worked fine for me in FF but for another user it didn't work on FF) the $_FILES['upload_file']['type'] was coming up as "application/vnd.ms-excel" instead of the expected "text/csv" or "text/plain".

So I resorted to using the (IMHO) much more reliable finfo_* functions something like this:

$acceptable_mime_types = array('text/plain', 'text/csv', 'text/comma-separated-values');

if (!empty($_FILES) && array_key_exists('upload_file', $_FILES) && $_FILES['upload_file']['error'] == UPLOAD_ERR_OK) {
    $tmpf = $_FILES['upload_file']['tmp_name'];

    // Make sure $tmpf is kosher, then:

    $finfo = finfo_open(FILEINFO_MIME_TYPE);
    $mime_type = finfo_file($finfo, $tmpf);

    if (!in_array($mime_type, $acceptable_mime_types)) {
        // Unacceptable mime type.
    }
}
