Please import Quartzcore framework then you have to set setMaskToBounds to TRUE this the very important line.

Then: [[yourView layer] setCornerRadius:5.0f];

\sf function_name in psql yields editable source code of a single function.

From https://www.postgresql.org/docs/9.6/static/app-psql.html:

\sf[+] function_description This command fetches and shows the definition of the named function, in the form of a CREATE OR REPLACE FUNCTION command.

If + is appended to the command name, then the output lines are numbered, with the first line of the function body being line 1.

I also got this exact error log on my AWS EC2 instance.

There were no connection leaks since I was just deploying the alpha application (no real users), and I confirmed with Activity Monitor and sp_who that there are in fact no connections to the database.

My issue was AWS related - more specifically, with the Security Groups. See, only certain security groups had access to the RDS server where I hosted the database. I added an ingress rule with authorize-security-group-ingress command to allow access to the correct EC2 instance to the RDS server by using --source-group-name parameter. The ingress rule was added, I could see that on the AWS UI - but I got this error.

When I removed and then added the ingress rule manually on AWS UI - suddenly the exception was no more and the app was working.

Try reinterpret_cast

unsigned char *foo();
std::string str;
str.append(reinterpret_cast<const char*>(foo()));

Easy:

print mystring[:100]

Use alter session set current_schema = <username>, in your case as an execute immediate.

See Oracle's documentation for further information.

In your case, that would probably boil down to (untested)

DECLARE

   CURSOR client_cur IS
     SELECT  distinct username 
       from all_users 
      where length(username) = 3;

   -- client cursor 
   CURSOR emails_cur IS
   SELECT id, name 
     FROM org;

BEGIN

   FOR client IN client_cur LOOP

   -- ****
      execute immediate 
     'alter session set current_schema = ' || client.username;
   -- ****

      FOR email_rec in client_cur LOOP

         dbms_output.put_line(
             'Org id is ' || email_rec.id || 
             ' org nam '  || email_rec.name);

      END LOOP;

  END LOOP;
END;

USE LIMIT 1 - so It will return only 1 row. Example

customerId- (select id from enumeration where enumerations.name = 'Ready To Invoice' limit 1)

django-admin --version
python manage.py --version
pip freeze | grep django

I encountered a similar problem only with a nested img in my anchor:

<a href="some/link">
   <img src="some/src">
</a>

When I applied

@media print {
   a[href]:after {
      content: none !important;
   }
}

I lost my img and the entire anchor width for some reason, so instead I used:

@media print {
   a[href]:after {
      visibility: hidden;
   }
}

which worked perfectly.

Bonus tip: inspect print preview

This is not a PowerShell-specific answer, but you could authenticate against the share using "NET USE" first:

net use \\server\share /user:<domain\username> <password>

And then do whatever you need to do in PowerShell...

A Data Warehouse is a type of Data Structure usually housed on a Database. The Data Warehouse refers the the data model and what type of data is stored there - data that is modeled (data model) to server an analytical purpose.

A Database can be classified as any structure that houses data. Traditionally that would be an RDBMS like Oracle, SQL Server, or MySQL. However a Database can also be a NoSQL Database like Apache Cassandra, or an columnar MPP like AWS RedShift.

You see a database is simply a place to store data; a data warehouse is a specific way to store data and serves a specific purpose, which is to serve analytical queries.

OLTP vs OLAP does not tell you the difference between a DW and a Database, both OLTP and OLAP reside on databases. They just store data in a different fashion (different data model methodologies) and serve different purposes (OLTP - record transactions, optimized for updates; OLAP - analyze information, optimized for reads).

My answer is inspired on my own working experience, and mostly in the book Two Scoops of Django which I highly recommend, and where you can find a more detailed explanation of everything. I just will answer some of the points, and any improvement or correction will be welcomed. But there also can be more correct manners to achieve the same purpose.

Projects
I have a main folder in my personal directory where I maintain all the projects where I am working on.

Source Files
I personally use the django project root as repository root of my projects. But in the book is recommended to separate both things. I think that this is a better approach, so I hope to start making the change progressively on my projects.

project_repository_folder/
    .gitignore
    Makefile
    LICENSE.rst
    docs/
    README.rst
    requirements.txt
    project_folder/
        manage.py
        media/
        app-1/
        app-2/
        ...
        app-n/
        static/
        templates/
        project/
            __init__.py
            settings/
                __init__.py
                base.py
                dev.py
                local.py
                test.py
                production.py
            ulrs.py
            wsgi.py

Repository
Git or Mercurial seem to be the most popular version control systems among Django developers. And the most popular hosting services for backups GitHub and Bitbucket.

Virtual Environment
I use virtualenv and virtualenvwrapper. After installing the second one, you need to set up your working directory. Mine is on my /home/envs directory, as it is recommended on virtualenvwrapper installation guide. But I don't think the most important thing is where is it placed. The most important thing when working with virtual environments is keeping requirements.txt file up to date.

IntelliJ IDEA 2018.3.6

Using macOS Mojave Version 10.14.4 and pressing ?F12(Alt+F12) will open Sound preferences.

A solution without changing the current keymap is to use the command above with the key fn.

fn ? F12(fn+Alt+F12) will open the Terminal. And you can use ShiftEsc to close it.

Here's a more concrete example of how to access GET parameters. The Request object has a method that parses them out for you called Query:

Assuming a request URL like http://host:port/something?param1=b

func newHandler(w http.ResponseWriter, r *http.Request) {
  fmt.Println("GET params were:", r.URL.Query())

  // if only one expected
  param1 := r.URL.Query().Get("param1")
  if param1 != "" {
    // ... process it, will be the first (only) if multiple were given
    // note: if they pass in like ?param1=&param2= param1 will also be "" :|
  }

  // if multiples possible, or to process empty values like param1 in
  // ?param1=&param2=something
  param1s := r.URL.Query()["param1"]
  if len(param1s) > 0 {
    // ... process them ... or you could just iterate over them without a check
    // this way you can also tell if they passed in the parameter as the empty string
    // it will be an element of the array that is the empty string
  }    
}

Also note "the keys in a Values map [i.e. Query() return value] are case-sensitive."

The shortcut to comment out or uncomment the selected text or current line:

It was in a slightly different location for me than those listed above

Using an apostrophe ’ (Unicode: \u2019) instead of a single quote ' fixed the issue without doubling the \'.

java.time.Instant

Just use Instant of java.time.

    System.out.println(Instant.now());

This just printed:

2018-01-27T09:35:23.179612Z

Instant.toString always gives UTC time.

The output is usually sortable, but there are unfortunate exceptions. toString gives you enough groups of three decimals to render the precision it holds. On the Java 9 on my Mac the precision of Instant.now() seems to be microseconds, but we should expect that in approximately one case out of a thousand it will hit a whole number of milliseconds and print only three decimals. Strings with unequal numbers of decimals will be sorted in the wrong order (unless you write a custom comparator to take this into account).

Instant is one of the classes in java.time, the modern Java date and time API, which I warmly recommend that you use instead of the outdated Date class. java.time is built into Java 8 and later and has also been backported to Java 6 and 7.

You can try using open-cv to save the file since it helps with image type conversions internally. The sample code:

import cv2
import numpy as np

def save(encoded_data, filename):
    nparr = np.fromstring(encoded_data.decode('base64'), np.uint8)
    img = cv2.imdecode(nparr, cv2.IMREAD_ANYCOLOR)
    return cv2.imwrite(filename, img)

Then somewhere in your code you can use it like this:

save(base_64_string, 'testfile.png');
save(base_64_string, 'testfile.jpg');
save(base_64_string, 'testfile.bmp');

While there is no functional difference between os.environ.get and os.getenv, there is a massive difference between os.putenv and setting entries on os.environ. os.putenv is broken, so you should default to os.environ.get simply to avoid the way os.getenv encourages you to use os.putenv for symmetry.

os.putenv changes the actual OS-level environment variables, but in a way that doesn't show up through os.getenv, os.environ, or any other stdlib way of inspecting environment variables:

>>> import os
>>> os.environ['asdf'] = 'fdsa'
>>> os.environ['asdf']
'fdsa'
>>> os.putenv('aaaa', 'bbbb')
>>> os.getenv('aaaa')
>>> os.environ.get('aaaa')

You'd probably have to make a ctypes call to the C-level getenv to see the real environment variables after calling os.putenv. (Launching a shell subprocess and asking it for its environment variables might work too, if you're very careful about escaping and --norc/--noprofile/anything else you need to do to avoid startup configuration, but it seems a lot harder to get right.)

If you use the "position:fixed; bottom:0;" your footer will always show at the bottom and will hide your content if the page is longer than the browser window.

Is 'clean' not good enough? Note that you can call msbuild with /t:clean from the command-line.

Just invoke ruby XXXXX.rb in terminal, if the interpreter is in your $PATH variable.

( this can hardly be a rails thing, until you have it running. )

This is a charset issue. As such, it can have gone wrong on many different levels, but most likely, the strings in your database are utf-8 encoded, and you are presenting them as iso-8859-1. Or the other way around.

The proper way to fix this problem, is to get your character-sets straight. The simplest strategy, since you're using PHP, is to use iso-8859-1 throughout your application. To do this, you must ensure that:

• All PHP source-files are saved as iso-8859-1 (Not to be confused with cp-1252).
• Your web-server is configured to serve files with charset=iso-8859-1
• Alternatively, you can override the webservers settings from within the PHP-document, using header.
• In addition, you may insert a meta-tag in you HTML, that specifies the same thing, but this isn't strictly needed.
• You may also specify the accept-charset attribute on your <form> elements.
• Database tables are defined with encoding as latin1
• The database connection between PHP to and database is set to latin1

If you already have data in your database, you should be aware that they are probably messed up already. If you are not already in production phase, just wipe it all and start over. Otherwise you'll have to do some data cleanup.

A note on meta-tags, since everybody misunderstands what they are:

When a web-server serves a file (A HTML-document), it sends some information, that isn't presented directly in the browser. This is known as HTTP-headers. One such header, is the Content-Type header, which specifies the mimetype of the file (Eg. text/html) as well as the encoding (aka charset). While most webservers will send a Content-Type header with charset info, it's optional. If it isn't present, the browser will instead interpret any meta-tags with http-equiv="Content-Type". It's important to realise that the meta-tag is only interpreted if the webserver doesn't send the header. In practice this means that it's only used if the page is saved to disk and then opened from there.

This page has a very good explanation of these things.

You can simply prevent the default behavior of the click event directly in your template.

<a href="#" ng-click="$event.preventDefault();logout()" />

Per the angular documentation,

Directives like ngClick and ngFocus expose a $event object within the scope of that expression.

TCP / HTTP Listening On Ports: How Can Many Users Share the Same Port

So, what happens when a server listen for incoming connections on a TCP port? For example, let's say you have a web-server on port 80. Let's assume that your computer has the public IP address of 24.14.181.229 and the person that tries to connect to you has IP address 10.1.2.3. This person can connect to you by opening a TCP socket to 24.14.181.229:80. Simple enough.

Intuitively (and wrongly), most people assume that it looks something like this:

    Local Computer    | Remote Computer
    --------------------------------
    <local_ip>:80     | <foreign_ip>:80

    ^^ not actually what happens, but this is the conceptual model a lot of people have in mind.

This is intuitive, because from the standpoint of the client, he has an IP address, and connects to a server at IP:PORT. Since the client connects to port 80, then his port must be 80 too? This is a sensible thing to think, but actually not what happens. If that were to be correct, we could only serve one user per foreign IP address. Once a remote computer connects, then he would hog the port 80 to port 80 connection, and no one else could connect.

Three things must be understood:

1.) On a server, a process is listening on a port. Once it gets a connection, it hands it off to another thread. The communication never hogs the listening port.

2.) Connections are uniquely identified by the OS by the following 5-tuple: (local-IP, local-port, remote-IP, remote-port, protocol). If any element in the tuple is different, then this is a completely independent connection.

3.) When a client connects to a server, it picks a random, unused high-order source port. This way, a single client can have up to ~64k connections to the server for the same destination port.

So, this is really what gets created when a client connects to a server:

    Local Computer   | Remote Computer           | Role
    -----------------------------------------------------------
    0.0.0.0:80       | <none>                    | LISTENING
    127.0.0.1:80     | 10.1.2.3:<random_port>    | ESTABLISHED

Looking at What Actually Happens

First, let's use netstat to see what is happening on this computer. We will use port 500 instead of 80 (because a whole bunch of stuff is happening on port 80 as it is a common port, but functionally it does not make a difference).

    netstat -atnp | grep -i ":500 "

As expected, the output is blank. Now let's start a web server:

    sudo python3 -m http.server 500

Now, here is the output of running netstat again:

    Proto Recv-Q Send-Q Local Address           Foreign Address         State  
    tcp        0      0 0.0.0.0:500             0.0.0.0:*               LISTEN      - 

So now there is one process that is actively listening (State: LISTEN) on port 500. The local address is 0.0.0.0, which is code for "listening for all ip addresses". An easy mistake to make is to only listen on port 127.0.0.1, which will only accept connections from the current computer. So this is not a connection, this just means that a process requested to bind() to port IP, and that process is responsible for handling all connections to that port. This hints to the limitation that there can only be one process per computer listening on a port (there are ways to get around that using multiplexing, but this is a much more complicated topic). If a web-server is listening on port 80, it cannot share that port with other web-servers.

So now, let's connect a user to our machine:

    quicknet -m tcp -t localhost:500 -p Test payload.

This is a simple script (https://github.com/grokit/quickweb) that opens a TCP socket, sends the payload ("Test payload." in this case), waits a few seconds and disconnects. Doing netstat again while this is happening displays the following:

    Proto Recv-Q Send-Q Local Address           Foreign Address         State  
    tcp        0      0 0.0.0.0:500             0.0.0.0:*               LISTEN      -
    tcp        0      0 192.168.1.10:500        192.168.1.13:54240      ESTABLISHED -

If you connect with another client and do netstat again, you will see the following:

    Proto Recv-Q Send-Q Local Address           Foreign Address         State  
    tcp        0      0 0.0.0.0:500             0.0.0.0:*               LISTEN      -
    tcp        0      0 192.168.1.10:500        192.168.1.13:26813      ESTABLISHED -

... that is, the client used another random port for the connection. So there is never confusion between the IP addresses.

Sorry, but it might even be more complicated, involving pbkdf2, or even a variation of it. Listen to the WWDC 2010 session #209, which mainly talks about the security measures in iOS 4, but also mentions briefly the separate encryption of backups and how they're related.

You can be pretty sure that without knowing the password, there's no way you can decrypt it, even by brute force.

Let's just assume you want to try to enable people who KNOW the password to get to the data of their backups.

I fear there's no way around looking at the actual code in iTunes in order to figure out which algos are employed.

Back in the Newton days, I had to decrypt data from a program and was able to call its decryption function directly (knowing the password, of course) without the need to even undersand its algorithm. It's not that easy anymore, unfortunately.

I'm sure there are skilled people around who could reverse engineer that iTunes code - you just have to get them interested.

In theory, Apple's algos should be designed in a way that makes the data still safe (i.e. practically unbreakable by brute force methods) to any attacker knowing the exact encryption method. And in WWDC session 209 they went pretty deep into details about what they do to accomplish this. Maybe you can actually get answers directly from Apple's security team if you tell them your good intentions. After all, even they should know that security by obfuscation is not really efficient. Try their security mailing list. Even if they do not repond, maybe someone else silently on the list will respond with some help.

Good luck!

This works like magic, use it in the CSS file on the div you want to have on the new line:

.div_class {
    clear: left;
}

Or declare it in the html:

<div style="clear: left">
     <!-- Content... -->
</div>

I get a better result setting this class:

.modal-dialog {
  position: absolute;
  top: 50px;
  right: 100px;
  bottom: 0;
  left: 0;
  z-index: 10040;
  overflow: auto;
  overflow-y: auto;
}

According to DOM Level 2 Events, the load event is supposed to fire on document, not on window. However, load is implemented on window in all browsers for backwards compatibility.

There is an excellent book about the topic:

http://www.amazon.com/Texturing-Modeling-Third-Procedural-Approach/dp/1558608486

It is biased toward non-real-time visual effects and animation generation, but the theory and ideas are usable outside of these fields, I suppose.

It may also worth to mention that there is a professional software package that implements a complete procedural workflow called SideFX's Houdini. You can use it to invent and prototype procedural solutions to problems, that you can later translate to code.

While it's a rather expensive package, it has a free evaluation licence, which can be used as a very nice educational and/or engineering tool.

The easy way to install scipy on Windows 10 100% is this: Just pip this ====> pip install scipy==1.0.0rc2

Thank me later :)

Untested, but illustrating my idea:

boolean IsNegative<T>(T v) {
  return (v & ((T)-1));
}

I had the same issue. And in my case the fix was pretty simple. The trick is to simply add the ".exe" to your compilers path. So, instead of :

SET(CMAKE_C_COMPILER C:/MinGW/bin/gcc)

It should be

SET(CMAKE_C_COMPILER C:/MinGW/bin/gcc.exe)

The same applies for g++.

class Program
{
    Variable va = new Variable();
    static void Main(string[] args)
    {
        va.name = "Stackoverflow";
    }
}

I use to throw an exception in the base class.

protected abstractMethod() {
    throw new Error("abstractMethod not implemented");
}

Then you have to implement in the sub-class. The cons is that there is no build error, but run-time. The pros is that you can call this method from the super class, assuming that it will work :)

HTH!

On 5.1 I could only get this to work.

<a href="{{ URL::previous() }}" class="btn btn-default">Back</a>

If you installed from the DMG on a mac, it created a mysql client but did not put it in your user path.

Add this to your .bash_profile:

export PATH="/usr/local/mysql/bin:$PATH

This will let you run mysql from anywhere as you.

I have been in stuck with similar problem. Finally figured out the what was the root cause in my particular case. If you read the data from multiple XML files that lie in same folder you will parse also .DS_Store file. Before parsing add this condition

for file in files:
    if file.endswith('.xml'):
       run_your_code...

This trick helped me as well

(?<![^d])\d+(?:\.\d+)?(?![^d])

clean and simple.

This uses Suffix and Prefix, RegEx features.

It directly returns true - false for IsMatch condition

This will return what you asked, but I wouldnt recommend using css like this. Use external CSS instead of inline css.

$("tr[id='pDetails']").attr("style").split(':')[1];

To convert a string into a date, the easiest way AFAIK is the dateutil module:

import dateutil.parser
datetime_object = dateutil.parser.parse("2013-05-07")

It can also handle time zones:

print(dateutil.parser.parse("2013-05-07"))
>>> datetime.datetime(2013, 5, 7, 1, 12, 12, tzinfo=tzutc())

If you have a datetime object, say:

import pytz
import datetime
now = datetime.datetime.now(pytz.UTC)

and you want chop off the time part, then I think it is easier to construct a new object instead of "substracting the time part". It is shorter and more bullet proof:

date_part datetime.datetime(now.year, now.month, now.day, tzinfo=now.tzinfo)

It also keeps the time zone information, it is easier to read and understand than a timedelta substraction, and you also have the option to give a different time zone in the same step (which makes sense, since you will have zero time part anyway).

If you have multiple checkboxes on the same form

The controller code

vm.doYouHaveCheckBox = ['aaa', 'ccc', 'bbb'];
vm.desiredRoutesCheckBox = ['ddd', 'ccc', 'Default'];
vm.doYouHaveCBSelection = [];
vm.desiredRoutesCBSelection = [];

View code

<div ng-repeat="doYouHaveOption in vm.doYouHaveCheckBox">
    <div class="action-checkbox">
        <input id="{{doYouHaveOption}}" type="checkbox" value="{{doYouHaveOption}}" ng-checked="vm.doYouHaveCBSelection.indexOf(doYouHaveOption) > -1" ng-click="vm.toggleSelection(doYouHaveOption,vm.doYouHaveCBSelection)" />
        <label for="{{doYouHaveOption}}"></label>
        {{doYouHaveOption}}
    </div>

So my answer ended up being a solution that allows me to use the _this variable pointing to the original object. I create a new instance of a "Square" however I hated the way the "Square" generated it's size. I thought it should follow my specific needs. However in order to do so I needed the square to have an updated "GetSize" function with the internals of that function calling other functions already existing in the square such as this.height, this.GetVolume(). But in order to do so I needed to do this without any crazy hacks. So here is my solution.

Some other Object initializer or helper function.

this.viewer = new Autodesk.Viewing.Private.GuiViewer3D(
  this.viewerContainer)
var viewer = this.viewer;
viewer.updateToolbarButtons =  this.updateToolbarButtons(viewer);

Function in the other object.

updateToolbarButtons = function(viewer) {
  var _viewer = viewer;
  return function(width, height){ 
blah blah black sheep I can refer to this.anything();
}
};

(Assuming you are not required to input the string from directly within Python code)

to get around the Issue Andrew Dalke pointed out, simply type the literal string into a text file and then use this;

input_ = '/directory_of_text_file/your_text_file.txt' 
input_open   = open(input_,'r+')
input_string = input_open.read()

print input_string

This will print the literal text of whatever is in the text file, even if it is;

 '   ''' """  “ \

Not fun or optimal, but can be useful, especially if you have 3 pages of code that would’ve needed character escaping.

An incredibly powerful alternative to other answers here:

ng-class="[  { key: resulting-class-expression }[ key-matching-expression ], ..  ]"

Some examples:

1. Simply adds 'class1 class2 class3' to the div:

<div ng-class="[{true: 'class1'}[true], {true: 'class2 class3'}[true]]"></div>

2. Adds 'odd' or 'even' classes to div, depending on the $index:

<div ng-class="[{0:'even', 1:'odd'}[ $index % 2]]"></div>

3. Dynamically creates a class for each div based on $index

<div ng-class="[{true:'index'+$index}[true]]"></div>

If $index=5 this will result in:

<div class="index5"></div>

Here's a code sample you can run:

var app = angular.module('app', []); _x000D_
app.controller('MyCtrl', function($scope){_x000D_
  $scope.items = 'abcdefg'.split('');_x000D_
}); 

.odd  { background-color: #eee; }_x000D_
.even { background-color: #fff; }_x000D_
.index5 {background-color: #0095ff; color: white; font-weight: bold; }_x000D_
* { font-family: "Courier New", Courier, monospace; }

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.1/angular.min.js"></script>_x000D_
_x000D_
<div ng-app="app" ng-controller="MyCtrl">_x000D_
  <div ng-repeat="item in items"_x000D_
    ng-class="[{true:'index'+$index}[true], {0:'even', 1:'odd'}[ $index % 2 ]]">_x000D_
    index {{$index}} = "{{item}}" ng-class="{{[{true:'index'+$index}[true], {0:'even', 1:'odd'}[ $index % 2 ]].join(' ')}}"_x000D_
  </div>_x000D_
</div>

class MyParent:

    def sayHi():
        print('Mamma says hi')

from path.to.MyParent import MyParent

class ChildClass(MyParent):
    pass

An instance of ChildClass will then inherit the sayHi() method.

select * into mytable_backup from mytable

Makes a copy of table mytable, and every row in it, called mytable_backup.

So after running brew install mcrypt php, I had to install php-mcrypt via pecl:

pecl install mcrypt-1.0.1

At the time of writing, mcrypt does not have a stable pecl release, 1.0.1 being the current release for php 7.2 and 7.3, and brew install php will install php 7.2.

if (file_exists('http://www.mydomain.com/images/'.$filename)) {}

This didn't work for me. The way I did it was using getimagesize.

$src = 'http://www.mydomain.com/images/'.$filename;

if (@getimagesize($src)) {

Note that the '@' will mean that if the image does not exist (in which case the function would usually throw an error: getimagesize(http://www.mydomain.com/images/filename.png) [function.getimagesize]: failed) it will return false.

dups = collections.defaultdict(list)
for i, e in enumerate(L):
  dups[e].append(i)
for k, v in sorted(dups.iteritems()):
  if len(v) >= 2:
    print '%s: %r' % (k, v)

And extrapolate from there.

You appear to have a heredoc containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF

or if BUILDING is $2 in your script:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF

If your file.sql had an exit at the end then it would be even simpler as you wouldn't need the heredoc:

sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2

In your SQL you can then refer to the position parameters using substitution variables:

...
}',SEM_Models('&1'),NULL,
...

The &1 will be replaced with the first value passed to the SQL script, BUILDING; because that is a string it still needs to be enclosed in quotes. You might want to set verify off to stop if showing you the substitutions in the output.

You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1, the second is &2, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF

or:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF

If total_count is being passed to your shell script then just use its positional parameter, $4 or whatever. And your SQL would then be:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:

define MY_ALIAS = &1
define MY_MODEL = &2

SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

From your separate question, maybe you just wanted:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

... so the alias will be the same value you're querying on (the value in $2, or BUILDING in the original part of the answer). You can refer to a substitution variable as many times as you want.

That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:

select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT

If you set pages 0 and set heading off, your repeated calls might appear in a neat list. You might also need to set tab off and possibly use rpad('&1', 20) or similar to make that column always the same width. Or get the results as CSV with:

select '&1' ||','|| COUNT(*)

Depends what you're using the results for...

The easiest way is to use the modulus division operator.

if ($counter % 3 == 0) {
   echo 'image file';
}

How this works: Modulus division returns the remainder. The remainder is always equal to 0 when you are at an even multiple.

There is one catch: 0 % 3 is equal to 0. This could result in unexpected results if your counter starts at 0.

If you still want to use View controller-based status bar appearance in info.plist set to YES, meaning that you can change the statusbar for each view-controller, use the following for white text in the status-bar in ViewDidLoad:

[[[self navigationController] navigationBar] setBarStyle:UIBarStyleBlackTranslucent];

Another approach is to use @ExceptionHandler with @ControllerAdvice to centralize all your handlers in the same class, if not you must put the handler methods in every controller you want to manage an exception.

Your handler class:

@ControllerAdvice
public class MyExceptionHandler extends ResponseEntityExceptionHandler {

  @ExceptionHandler(MyBadRequestException.class)
  public ResponseEntity<MyError> handleException(MyBadRequestException e) {
    return ResponseEntity
        .badRequest()
        .body(new MyError(HttpStatus.BAD_REQUEST, e.getDescription()));
  }
}

Your custom exception:

public class MyBadRequestException extends RuntimeException {

  private String description;

  public MyBadRequestException(String description) {
    this.description = description;
  }

  public String getDescription() {
    return this.description;
  }
}

Now you can throw exceptions from any of your controllers, and you can define other handlers inside you advice class.

I do realize that the author asks question in relation to a class-based component, however I think it's worth mentioning that as of React 16.8.0 (February 6, 2019) you can take advantage of hooks in function-based components.

Example code:

import { useRef } from 'react'

function Component() {
  const inputRef = useRef()

  return (
    <input ref={inputRef} />
    <div
      onScroll={() => {
        const { offsetTop } = inputRef.current
        ...
      }}
    >
  )
}

  yearList = arrayListOf()
    for (year in 1950 until 2021) {
        yearList.add(year)
    }

   yearList.reverse()
    val list: ArrayList<String> = arrayListOf()

    for (year in yearList) {
        list.add(year.toString())
    }

\App::call('App\Http\Controllers\MyController@getFoo')

on android devices using chrome we can't detect a backspace. You can use workaround for it:

var oldInput = '',
    newInput = '';

 $("#ID").keyup(function () {
  newInput = $('#ID').val();
   if(newInput.length < oldInput.length){
      //backspace pressed
   }
   oldInput = newInput;
 })

As explained @Yaroslav Stavnichiy if a service is marked as transactional spring tries to handle transaction itself. If any exception occurs then a rollback operation performed. If in your scenario ServiceUser.method() is not performing any transactional operation you can use @Transactional.TxType annotation. 'NEVER' option is used to manage that method outside transactional context.

Transactional.TxType reference doc is here.

You just need to use the Gradle Application plugin:

apply plugin:'application'
mainClassName = "org.gradle.sample.Main"

And then simply gradle run.

As Teresa points out, you can also configure mainClassName as a system property and run with a command line argument.

I have solved similar problems by writing a Generic Extension Property Attribute Helper:

using System;
using System.Linq;
using System.Linq.Expressions;
using System.Reflection;

public static class AttributeHelper
{
    public static TValue GetPropertyAttributeValue<T, TOut, TAttribute, TValue>(
        Expression<Func<T, TOut>> propertyExpression, 
        Func<TAttribute, TValue> valueSelector) 
        where TAttribute : Attribute
    {
        var expression = (MemberExpression) propertyExpression.Body;
        var propertyInfo = (PropertyInfo) expression.Member;
        var attr = propertyInfo.GetCustomAttributes(typeof(TAttribute), true).FirstOrDefault() as TAttribute;
        return attr != null ? valueSelector(attr) : default(TValue);
    }
}

Usage:

var author = AttributeHelper.GetPropertyAttributeValue<Book, string, AuthorAttribute, string>(prop => prop.Name, attr => attr.Author);
// author = "AuthorName"

Try this:

window.open(url, '_blank');

This will open in new tab (if your code is synchronous and in this case it is. in other case it would open a window)

import sys, os

try:
    raise NotImplementedError("No error")
except Exception as e:
    exc_type, exc_obj, exc_tb = sys.exc_info()
    fname = os.path.split(exc_tb.tb_frame.f_code.co_filename)[1]
    print(exc_type, fname, exc_tb.tb_lineno)

Consider using Joda Time. I love this library and wish it would replace the current horrible mess that are the existing Java Date and Calendar classes. It's date handling done right.

EDIT: It's not 2009 any more, and Java 8's been out for ages. Use Java 8's built in java.time classes which are based on Joda Time, as Basil Bourque mentions above. In this case you'll want the Period class, and here's Oracle's tutorial on how to use it.

I solved this, without having to completely reinstall Visual Studio 2013.

For those who may come across this in the future, the following steps worked for me:

1. Run the ISO (or vs_professional.exe).

2. If you get the error below, you need to update the Windows Registry to trick the installer into thinking you still have the base version. If you don't get this error, skip to step 3

   • Click the link for 'examine the log file' and look near the bottom of the log, for this line:

   • open regedit.exe and do an Edit > Find... for that GUID. In my case it was {6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}. This was found in:

     HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall{6dff50d0-3bc3-4a92-b724-bf6d6a99de4f}

   • Edit the BundleVersion value and change it to a lower version. I changed mine from 12.0.21005.13 to 12.0.21000.13:

   • Exit the registry

3. Run the ISO (or vs_professional.exe) again. If it has a repair button like the image below, you can skip to step 4.

   

   • Otherwise you have to let the installer fix the registry. I did this by "installing" at least one feature, even though I think I already had all features (they were not detected). This took about 20 minutes.

4. Run the ISO (or vs_professional.exe) again. This time repair should be visible.

5. Click Repair and let it update your installation and apply its embedded license key. This took about 20 minutes.

Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help > Register Product:

Hope this helps somebody in the future!

Changing

RestResponse response = client.Execute(request);

to

IRestResponse response = client.Execute(request);

worked for me.

I have come to this post looking for help while using Spring Webflux with Mongo Repository.

My error was similar to owner

Field usersRepository in foobar.UsersService required
a bean of type 'foobar.UsersRepository' that could not be found.

As I was working before with Spring MVC I was surprised by this error.

Because finding help was not so obvious I'm putting answer to this question as it is somehow related and this question is high in search results.

First thing is you must remember about what was mentioned in answer marked as accepted - package hierarchy.

Second important thing is that if you use Webflux you need to use some different package while when using Spring MVC e.g. for MongoDB you need to add

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb-reactive</artifactId>
</dependency>

with -reactive at the end.

You can use find with a Predicate as follows:

list.Find(x => x.Id == IdToFind);

This will return the first object in the list which meets the conditions defined by the predicate (ie in my example I am looking for an object with an ID).

Xform to double (and back) for a simple ceil?

list.Count()/10 + (list.Count()%10 >0?1:0) - this bad, div + mod

edit 1st: on a 2n thought that's probably faster (depends on the optimization): div * mul (mul is faster than div and mod)

int c=list.Count()/10;
if (c*10<list.Count()) c++;

edit2 scarpe all. forgot the most natural (adding 9 ensures rounding up for integers)

(list.Count()+9)/10

Book.where.any_of(Book.where(:author => 'Poe'), Book.where(:author => 'Hemingway')

I had this issue with cap = cv2.VideoCapture(0). I changed this to cap = cv2.VideoCapture(1) and then it worked. Since it wasn't linked to the right webcam it was returning nothing. Maybe this will help good luck.

It seems that you can't do all this in a trigger. According to the documentation:

Within a stored function or trigger, it is not permitted to modify a table that is already being used (for reading or writing) by the statement that invoked the function or trigger.

According to this answer, it seems that you should:

create a stored procedure, that inserts into/Updates the target table, then updates the other row(s), all in a transaction.

With a stored proc you'll manually commit the changes (insert and update). I haven't done this in MySQL, but this post looks like a good example.

I've ended up with the solution below, which can work with either an attribute, <a href="..." disabled="disabled">, or a class <a href="..." class="disabled">:

CSS Styles:

a[disabled=disabled], a.disabled {
    color: gray;
    cursor: default;
}

a[disabled=disabled]:hover, a.disabled:hover {
    text-decoration: none;
}

Javascript (in jQuery ready):

$("a[disabled], a.disabled").on("click", function(e){

    var $this = $(this);
    if ($this.is("[disabled=disabled]") || $this.hasClass("disabled"))
        e.preventDefault();
})

In XML use:

android:editable="false"

As an example:

<EditText
    android:id="@+id/EditText1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:editable="false" />

in Bash, to source some command's output, instead of a file:

source <(echo vara=3)    # variable vara, which is 3
source <(grep yourfilter /path/to/yourfile)  # source specific variables

reference

You can use this method.

    public static File getRobotCacheFile(Context context) throws IOException {
        File cacheFile = new File(context.getCacheDir(), "robot.png");
        try {
            InputStream inputStream = context.getAssets().open("robot.png");
            try {
                FileOutputStream outputStream = new FileOutputStream(cacheFile);
                try {
                    byte[] buf = new byte[1024];
                    int len;
                    while ((len = inputStream.read(buf)) > 0) {
                        outputStream.write(buf, 0, len);
                    }
                } finally {
                    outputStream.close();
                }
            } finally {
                inputStream.close();
            }
        } catch (IOException e) {
            throw new IOException("Could not open robot png", e);
        }
        return cacheFile;
    }

You should never use InputStream.available() in such cases. It returns only bytes that are buffered. Method with .available() will never work with bigger files and will not work on some devices at all.

In Kotlin (;D):

@Throws(IOException::class)
fun getRobotCacheFile(context: Context): File = File(context.cacheDir, "robot.png")
    .also {
        it.outputStream().use { cache -> context.assets.open("robot.png").use { it.copyTo(cache) } }
    }

Expanding on Jeff Paulsen answer. I wanted to make sure it didn't matter how many number or char groups were in the strings:

public class SemiNumericComparer : IComparer<string>
{
    public int Compare(string s1, string s2)
    {
        if (int.TryParse(s1, out var i1) && int.TryParse(s2, out var i2))
        {
            if (i1 > i2)
            {
                return 1;
            }

            if (i1 < i2)
            {
                return -1;
            }

            if (i1 == i2)
            {
                return 0;
            }
        }

        var text1 = SplitCharsAndNums(s1);
        var text2 = SplitCharsAndNums(s2);

        if (text1.Length > 1 && text2.Length > 1)
        {

            for (var i = 0; i < Math.Max(text1.Length, text2.Length); i++)
            {

                if (text1[i] != null && text2[i] != null)
                {
                    var pos = Compare(text1[i], text2[i]);
                    if (pos != 0)
                    {
                        return pos;
                    }
                }
                else
                {
                    //text1[i] is null there for the string is shorter and comes before a longer string.
                    if (text1[i] == null)
                    {
                        return -1;
                    }
                    if (text2[i] == null)
                    {
                        return 1;
                    }
                }
            }
        }

        return string.Compare(s1, s2, true);
    }

    private string[] SplitCharsAndNums(string text)
    {
        var sb = new StringBuilder();
        for (var i = 0; i < text.Length - 1; i++)
        {
            if ((!char.IsDigit(text[i]) && char.IsDigit(text[i + 1])) ||
                (char.IsDigit(text[i]) && !char.IsDigit(text[i + 1])))
            {
                sb.Append(text[i]);
                sb.Append(" ");
            }
            else
            {
                sb.Append(text[i]);
            }
        }

        sb.Append(text[text.Length - 1]);

        return sb.ToString().Split(' ');
    }
}

I also took SplitCharsAndNums from an SO Page after amending it to deal with file names.

Serialisation in java is not meant as long term persistence or transport format - it is too fragile for this. With the slightest difference in class bytecode and JVM, your data is not readable anymore. Use XML or JSON data-binding for your task (XStream is fast and easy to use, and there are a ton of alternatives)

Why not try with what angular docs mention https://docs.angularjs.org/api/ng/function/angular.element.

angular.element(callback)

I've used this inside my $onInit(){...} function.

 var self = this;

 angular.element(function () {
        var target = document.getElementsByClassName('unitSortingModule');
        target[0].addEventListener("touchstart", self.touchHandler, false);
        ...
    });

This worked for me.

If you are a windows 10 + TortoiseGit 2.7 user:

1. for the first time login, simply follow the prompts to enter your credentials and save password.
2. If you ever need to update your credentials, don't waste your time at the TortoiseGit settings. Instead, windows search>Credential Manager> Windows Credentials > find your git entry > Edit.

Efficient and short.

        return builder.toString();
    }
}

For those wanting a simple solution without jQuery, here's a way.

textarea and message container to put in your form:

<textarea onKeyUp="count_it()" id="text" name="text"></textarea>
Length <span id="counter"></span>

JavaScript:

<script>
function count_it() {
    document.getElementById('counter').innerHTML = document.getElementById('text').value.length;
}
count_it();
</script>

The script counts the characters initially and then for every keystroke and puts the number in the counter span.

Native Node.js solution is:

const {execSync} = require('child_process');

const result = execSync('node -v'); //  this do the trick 

Just be aware that some commands returns Buffer instead of string. And if you need string just add encoding to execSync options:

const result = execSync('git rev-parse HEAD', {encoding: 'utf8'});

... and it is also good to have timeout on sync exec:

const result = execSync('git rev-parse HEAD', {encoding: 'utf8', timeout: 10000});

With bash

a="The cat sat on the mat"
b=cat
strindex() { 
  x="${1%%$2*}"
  [[ "$x" = "$1" ]] && echo -1 || echo "${#x}"
}
strindex "$a" "$b"   # prints 4
strindex "$a" foo    # prints -1

You can create a character array that does this via a loop:

>> for i=1:10
Names(i,:)='Sample Text';
end
>> Names

Names =

Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text

However, this would be better implemented using REPMAT:

>> Names = repmat('Sample Text', 10, 1)

Names =

Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text

This will correctly handle the issues with the birthday and rounding:

DECLARE @dob  datetime
SET @dob='1992-01-09 00:00:00'

SELECT DATEDIFF(YEAR, '0:0', getdate()-@dob)

Another reason you can get this error is that Eclipse can't find the correct file.

Check out where Eclipse is looking for your SDK files. You can do this on the command line. Below is an example for the windows command prompt for an avd I created and named 'SonyTabletS':

c:\Program Files (x86)\Android\android-sdk\tools> emulator @SonyTabletS -verbose

The first line returned shows where eclipse is looking for the SDK files and will look something like:

emulator: found ANDROID_SDK_ROOT: C:\Program Files (x86)\Android\android-sdk

Make sure that location is correct.

In my case, ANDROID_SDK_ROOT was initially set incorrectly to my home directory. This is because I set it that way by blindly following the Sony Tablet S SDK install instructions and adding an ANDROID_SDK_ROOT environment variable with the incorrect path.

find supports wildcard matches, just add a *:

find / -type d -name "ora10*"

You are doing mistake in "configuration_page.jsp" file. here in this file , function loadXMLDoc() 's line number 2 should be like this:

var config=document.getElementsByName('configselect').value;

because you have declared only the name attribute in your <select> tag. So you should get this element by name.

After correcting this, it will run without any JavaScript error

Setting project's SDK in IntelliJ (File > Project Structure > Project:Project SDK) worked for me

This is basically Marco Antônio's answer for a React custom hook, but modified to set the dimensions initially and not only after a resize.

export const useContainerDimensions = myRef => {
  const getDimensions = () => ({
    width: myRef.current.offsetWidth,
    height: myRef.current.offsetHeight
  })

  const [dimensions, setDimensions] = useState({ width: 0, height: 0 })

  useEffect(() => {
    const handleResize = () => {
      setDimensions(getDimensions())
    }

    if (myRef.current) {
      setDimensions(getDimensions())
    }

    window.addEventListener("resize", handleResize)

    return () => {
      window.removeEventListener("resize", handleResize)
    }
  }, [myRef])

  return dimensions;
};

Used in the same way:

const MyComponent = () => {
  const componentRef = useRef()
  const { width, height } = useContainerDimensions(componentRef)

  return (
    <div ref={componentRef}>
      <p>width: {width}px</p>
      <p>height: {height}px</p>
    <div/>
  )
}

For Sticky Footer we use two DIV's in the HTML for basic sticky footer effect. Write like this:

HTML

<div class="container"></div>

<div class="footer"></div>

CSS

body,html {
    height:100%;
}
.container {
    min-height:100%;
}
.footer {
    height:40px;
    margin-top:-40px;
}

For simple cases like this, TimeUnit should be used. TimeUnit usage is a bit more explicit about what is being represented and is also much easier to read and write when compared to doing all of the arithmetic calculations explicitly. For example, to calculate the number days from milliseconds, the following statement would work:

    long days = TimeUnit.MILLISECONDS.toDays(milliseconds);

For cases more advanced, where more finely grained durations need to be represented in the context of working with time, an all encompassing and modern date/time API should be used. For JDK8+, java.time is now included (here are the tutorials and javadocs). For earlier versions of Java joda-time is a solid alternative.

my two cents about logic:

syntax is "old date" - :"new date", so:

SELECT TIMESTAMPDIFF(SECOND, '2018-11-15 15:00:00', '2018-11-15 15:00:30')

gives 30,

SELECT TIMESTAMPDIFF(SECOND, '2018-11-15 15:00:55', '2018-11-15 15:00:15')

gives: -40

host

var url = window.location.host;

returns localhost:2679

hostname

var url = window.location.hostname;

returns localhost

This solution is very close to what @domi has, but is designed to shorten the name by fetching first 4 letters and last number.

library(ggplot2)

# simulate some data
xy <- data.frame(hospital = rep(paste("Hospital #", 1:3, sep = ""), each = 30),
                 value = rnorm(90))

shortener <- function(string) {
  abb <- substr(string, start = 1, stop = 4) # fetch only first 4 strings
  num <- gsub("^.*(\\d{1})$", "\\1", string) # using regular expression, fetch last number
  out <- paste(abb, num) # put everything together
  out
}

ggplot(xy, aes(x = value)) +
  theme_bw() +
  geom_histogram() +
  facet_grid(hospital ~ ., labeller = labeller(hospital = shortener))

I realize this is on older question but just wanted to add that

Environment.NewLine

also works if doing this through code.

function setGetParameter(paramName, paramValue)
{
    var url = window.location.href;
    var hash = location.hash;
    url = url.replace(hash, '');
    if (url.indexOf(paramName + "=") >= 0)
    {
        var prefix = url.substring(0, url.indexOf(paramName + "=")); 
        var suffix = url.substring(url.indexOf(paramName + "="));
        suffix = suffix.substring(suffix.indexOf("=") + 1);
        suffix = (suffix.indexOf("&") >= 0) ? suffix.substring(suffix.indexOf("&")) : "";
        url = prefix + paramName + "=" + paramValue + suffix;
    }
    else
    {
    if (url.indexOf("?") < 0)
        url += "?" + paramName + "=" + paramValue;
    else
        url += "&" + paramName + "=" + paramValue;
    }
    window.location.href = url + hash;
}

Call the function above in your onclick event.

Try this:

Calendar calendar = Calendar.getInstance();
calendar.setTime(yourdate);
int hours = calendar.get(Calendar.HOUR_OF_DAY);
int minutes = calendar.get(Calendar.MINUTE);
int seconds = calendar.get(Calendar.SECOND);

Edit:

hours, minutes, seconds

above will be the hours, minutes and seconds after converting yourdate to System Timezone!

Since the question is how to replace ALL whitespaces

UPDATE `table` 
SET `col_name` = REPLACE
(REPLACE(REPLACE(`col_name`, ' ', ''), '\t', ''), '\n', '');

Because you seem to be unfamiliar with scripts, here is an example.

#!/bin/sh
# usage: svn st | x 2 | xargs rm
col=$1
shift
awk -v col="$col" '{print $col}' "${@--}"

If you save this in ~/bin/x and make sure ~/bin is in your PATH (now that is something you can and should put in your .bashrc) you have the shortest possible command for generally extracting column n; x n.

The script should do proper error checking and bail if invoked with a non-numeric argument or the incorrect number of arguments, etc; but expanding on this bare-bones essential version will be in unit 102.

Maybe you will want to extend the script to allow a different column delimiter. Awk by default parses input into fields on whitespace; to use a different delimiter, use -F ':' where : is the new delimiter. Implementing this as an option to the script makes it slightly longer, so I'm leaving that as an exercise for the reader.

Usage

Given a file file:

1 2 3
4 5 6

You can either pass it via stdin (using a useless cat merely as a placeholder for something more useful);

$ cat file | sh script.sh 2
2
5

Or provide it as an argument to the script:

$ sh script.sh 2 file
2
5

Here, sh script.sh is assuming that the script is saved as script.sh in the current directory; if you save it with a more useful name somewhere in your PATH and mark it executable, as in the instructions above, obviously use the useful name instead (and no sh).

You get the error because if can only evaluate a logical vector of length 1.

Maybe you miss the difference between & (|) and && (||). The shorter version works element-wise and the longer version uses only the first element of each vector, e.g.:

c(TRUE, TRUE) & c(TRUE, FALSE)
# [1] TRUE FALSE

# c(TRUE, TRUE) && c(TRUE, FALSE)
[1] TRUE

You don't need the if statement at all:

mut1 <- trip$Ref.y=='G' & trip$Variant.y=='T'|trip$Ref.y=='C' & trip$Variant.y=='A'
trip[mut1, "mutType"] <- "G:C to T:A"

mysql_query function is used for executing mysql query in php. mysql_query returns false if query execution fails.Alternatively you can try using mysql_error() function For e.g

$result=mysql_query($sql)

or

die(mysql_error());

In above code snippet if query execution fails then it will terminate the execution and display mysql error while execution of sql query.

I"m not sure if this will have a huge impact on performance but this has done the trick for me in the past:

var mobileHover = function () {
    $('*').on('touchstart', function () {
        $(this).trigger('hover');
    }).on('touchend', function () {
        $(this).trigger('hover');
    });
};

mobileHover();

Easy ASP.NET Core 3.0 and TagHelpers

[HtmlTargetElement("li", Attributes = "active-when")]
public class LiTagHelper : TagHelper
{
    public string ActiveWhen { get; set; }

    [ViewContext]
    [HtmlAttributeNotBound]
    public ViewContext ViewContextData { get; set; }

    public override void Process(TagHelperContext context, TagHelperOutput output)
    {
        if (ActiveWhen == null)
            return;

        var targetController = ActiveWhen.Split("/")[1];
        var targetAction = ActiveWhen.Split("/")[2];

        var currentController = ViewContextData.RouteData.Values["controller"].ToString();
        var currentAction = ViewContextData.RouteData.Values["action"].ToString();

        if (currentController.Equals(targetController) && currentAction.Equals(targetAction))

Include into your _ViewImports.cs:

@addTagHelper *, YourAssemblyName

Usage:

 <li active-when="/Home/Index">

For me, I used margin-left: auto; which is more responsive with horizontal resizing.

I think you are looking for this: RowHeaderMouseDoubleClick event

private void DgwModificar_RowHeaderMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e) {
...
}

to get the row index:

int indice = e.RowIndex

Use the java.util.concurrent.TimeUnit class:

String.format("%d min, %d sec", 
    TimeUnit.MILLISECONDS.toMinutes(millis),
    TimeUnit.MILLISECONDS.toSeconds(millis) - 
    TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis))
);

Note: TimeUnit is part of the Java 1.5 specification, but toMinutes was added as of Java 1.6.

To add a leading zero for values 0-9, just do:

String.format("%02d min, %02d sec", 
    TimeUnit.MILLISECONDS.toMinutes(millis),
    TimeUnit.MILLISECONDS.toSeconds(millis) - 
    TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis))
);

If TimeUnit or toMinutes are unsupported (such as on Android before API version 9), use the following equations:

int seconds = (int) (milliseconds / 1000) % 60 ;
int minutes = (int) ((milliseconds / (1000*60)) % 60);
int hours   = (int) ((milliseconds / (1000*60*60)) % 24);
//etc...

Some DateTime StringFormat samples I found useful. Lifted from C# Examples

DateTime dt = new DateTime(2008, 3, 9, 16, 5, 7, 123);

String.Format("{0:y yy yyy yyyy}", dt);  // "8 08 008 2008"   year
String.Format("{0:M MM MMM MMMM}", dt);  // "3 03 Mar March"  month
String.Format("{0:d dd ddd dddd}", dt);  // "9 09 Sun Sunday" day
String.Format("{0:h hh H HH}",     dt);  // "4 04 16 16"      hour 12/24
String.Format("{0:m mm}",          dt);  // "5 05"            minute
String.Format("{0:s ss}",          dt);  // "7 07"            second
String.Format("{0:f ff fff ffff}", dt);  // "1 12 123 1230"   sec.fraction
String.Format("{0:F FF FFF FFFF}", dt);  // "1 12 123 123"    without zeroes
String.Format("{0:t tt}",          dt);  // "P PM"            A.M. or P.M.
String.Format("{0:z zz zzz}",      dt);  // "-6 -06 -06:00"   time zone

It is true that there aren't "before triggers" in MSSQL. However, you could still track the changes that were made on the table, by using the "inserted" and "deleted" tables together. When an update causes the trigger to fire, the "inserted" table stores the new values and the "deleted" table stores the old values. Once having this info, you could relatively easy simulate the "before trigger" behaviour.

Looks like recently google changed it's security policy. The top rated answer no longer works, until you change your account settings as described here: https://support.google.com/accounts/answer/6010255?hl=en-GB

When you have a conflict during rebase you have three options:

• You can run git rebase --abort to completely undo the rebase. Git will return you to your branch's state as it was before git rebase was called.

• You can run git rebase --skip to completely skip the commit. That means that none of the changes introduced by the problematic commit will be included. It is very rare that you would choose this option.

• You can fix the conflict as iltempo said. When you're finished, you'll need to call git rebase --continue. My mergetool is kdiff3 but there are many more which you can use to solve conflicts. You only need to set your merge tool in git's settings so it can be invoked when you call git mergetool https://git-scm.com/docs/git-mergetool

If none of the above works for you, then go for a walk and try again :)

Here is a sample code

strFileName = "c:\test.xls"

Set objExcel = CreateObject("Excel.Application")
objExcel.Visible = True

Set objWorkbook = objExcel.Workbooks.Add()
objWorkbook.SaveAs(strFileName)

objExcel.Quit

There is a very simple solution using dense_rank()

dense_rank() over (partition by [Mth] order by [UserAccountKey]) 
+ dense_rank() over (partition by [Mth] order by [UserAccountKey] desc) 
- 1

This will give you exactly what you were asking for: The number of distinct UserAccountKeys within each month.

more.exe exists on Windows, ports of less are easily found (and the PowerShell Community Extensions, PSCX, includes one).

PowerShell doesn't really provide any alternative to separate programs for either, but for structured data Out-Grid can be helpful.

Head and Tail can both be emulated with Select-Object using the -First and -Last parameters respectively.

Sed functions are all available but structured rather differently. The filtering options are available in Where-Object (or via Foreach-Object and some state for ranges). Other, transforming, operations can be done with Select-Object and Foreach-Object.

However as PowerShell passes (.NET) objects – with all their typed structure, eg. dates remain DateTime instances – rather than just strings, which each command needs to parse itself, much of sed and other such programs are redundant.

First of all, read the warning! It says do not run composer as root! Secondly, you're probably using Xammp on your local which has the required php libraries as default.

But in your server you're missing ext-dom. php-xml has all the related packages you need. So, you can simply install it by running:

sudo apt-get update
sudo apt install php-xml

Most likely you are missing mbstring too. If you get the error, install this package as well with:

sudo apt-get install php-mbstring

Then run:

composer update
composer require cviebrock/eloquent-sluggable

I liked the solution in the earlier post.

I made a mini-class, called it class AlphabeticalHash. It also has a method called ap, which accepts one argument, a Hash, as input: ap variable. Akin to pp (pp variable)

But it will (try and) print in alphabetical list (its keys). Dunno if anyone else wants to use this, it's available as a gem, you can install it as such: gem install alphabetical_hash

For me, this is simple enough. If others need more functionality, let me know, I'll include it into the gem.

EDIT: Credit goes to Peter, who gave me the idea. :)

But that doesn't seem like the proper way to do it..

That is indeed the proper way to do it (or at least a proper way to do it). This is a key aspect of promises, they're a pipeline, and the data can be massaged by the various handlers in the pipeline.

Example:

const promises = [_x000D_
  new Promise(resolve => setTimeout(resolve, 0, 1)),_x000D_
  new Promise(resolve => setTimeout(resolve, 0, 2))_x000D_
];_x000D_
Promise.all(promises)_x000D_
  .then(data => {_x000D_
    console.log("First handler", data);_x000D_
    return data.map(entry => entry * 10);_x000D_
  })_x000D_
  .then(data => {_x000D_
    console.log("Second handler", data);_x000D_
  });

(catch handler omitted for brevity. In production code, always either propagate the promise, or handle rejection.)

The output we see from that is:

First handler [1,2]
Second handler [10,20]

...because the first handler gets the resolution of the two promises (1 and 2) as an array, and then creates a new array with each of those multiplied by 10 and returns it. The second handler gets what the first handler returned.

If the additional work you're doing is synchronous, you can also put it in the first handler:

Example:

const promises = [_x000D_
  new Promise(resolve => setTimeout(resolve, 0, 1)),_x000D_
  new Promise(resolve => setTimeout(resolve, 0, 2))_x000D_
];_x000D_
Promise.all(promises)_x000D_
  .then(data => {_x000D_
    console.log("Initial data", data);_x000D_
    data = data.map(entry => entry * 10);_x000D_
    console.log("Updated data", data);_x000D_
    return data;_x000D_
  });

...but if it's asynchronous you won't want to do that as it ends up getting nested, and the nesting can quickly get out of hand.

I added a ticket to add an option of some sort here:

https://github.com/pydata/pandas/issues/1450

In the meantime, result.fillna('') should do what you want

EDIT: in the development version (to be 0.8.0 final) if you specify an empty list of na_values, empty strings will stay empty strings in the result

Try

string reversed(temp.rbegin(), temp.rend());

EDIT: Elaborating as requested.

string::rbegin() and string::rend(), which stand for "reverse begin" and "reverse end" respectively, return reverse iterators into the string. These are objects supporting the standard iterator interface (operator* to dereference to an element, i.e. a character of the string, and operator++ to advance to the "next" element), such that rbegin() points to the last character of the string, rend() points to the first one, and advancing the iterator moves it to the previous character (this is what makes it a reverse iterator).

Finally, the constructor we are passing these iterators into is a string constructor of the form:

template <typename Iterator>
string(Iterator first, Iterator last);

which accepts a pair of iterators of any type denoting a range of characters, and initializes the string to that range of characters.

The solution that worked for me was to edit the registry key to enable long path behaviour, setting the value to 1. This is a new opt-in feature for Windows 10

HKLM\SYSTEM\CurrentControlSet\Control\FileSystem LongPathsEnabled (Type: REG_DWORD)

I got this solution from a named section of the article that @james-hill posted.

https://docs.microsoft.com/windows/desktop/FileIO/naming-a-file#maximum-path-length-limitation

Public Oracle Java 6 releases do not support TLSv1.2. Paid-for releases of Java 6 (post-EOL) might. (UPDATE - TLSv1.1 is available for Java 1.6 from update 111 onwards; source)

Contact Oracle sales.

Other alternatives are:

• Use an alternative JCE implementation such as Bouncy Castle. See this answer for details on how to do it. It changes the default SSLSocketFactory implementation, so that your application will use BC transparently. (Other answers show how to use the BC SSLSocketFactory implementation explicitly, but that approach will entail modifying application or library code that that is opening sockets.)

• Use an IBM Java 6 ... if available for your platform. According to "IBM SDK, Java Technology Edition fixes to mitigate against the POODLE security vulnerability (CVE-2014-3566)":

  "TLSv1.1 and TLSv1.2 are available only for Java 6 service refresh 10, Java 6.0.1 service refresh 1 (J9 VM2.6), and later releases."

However, I'd advise upgrading to a Java 11 (now). Java 6 was EOL'd in Feb 2013, and continuing to use it is potentially risky. Free Oracle Java 8 is EOL for many use-cases. (Tell or remind the boss / the client. They need to know.)

We should create a property with DbQuery not DbSet in the model for the db context like below...

public class MyContextContext : DbContext
{
    public virtual DbQuery<CheckoutInvoiceModel> CheckoutInvoice { get; set; } 
}

After than a method that can be used to return result

public async Task<IEnumerable<CheckoutInvoiceModel>> GetLabReceiptByReceiptNo(string labReceiptNo)
{
    var listing = new List<CheckoutInvoiceModel>();
    try
    {
        var sqlCommand = $@"[dbo].[Checkout_GetLabReceiptByReceiptNo] {labReceiptNo}";
        
        listing = await db.Set<CheckoutInvoiceModel>().FromSqlRaw(sqlCommand).ToListAsync();                       
                        
    }
    catch (Exception ex)
    {
        return null;
    }
    return listing;
}

From above example, we can use any one option you like.

Hope this helpful for you!

Just as an FYI, there is a library called breakpoints which detects the max-width as set in CSS and allows you to use it in JS if-else conditions using <=, <, >, >= and == signs. I found it quite useful. The payload size is under 3 KB.

You can see a complete example using java 8, recursion and streams -> Dijkstra algorithm with java

The suggested method str.title() does not work in all cases. For example:

string = "a b 3c"
string.title()
> "A B 3C"

instead of "A B 3c".

I think, it is better to do something like this:

def capitalize_words(string):
    words = string.split(" ") # just change the split(" ") method
    return ' '.join([word.capitalize() for word in words])

capitalize_words(string)
>'A B 3c'

You need to pass in a sequence, but you forgot the comma to make your parameters a tuple:

cursor.execute('INSERT INTO images VALUES(?)', (img,))

Without the comma, (img) is just a grouped expression, not a tuple, and thus the img string is treated as the input sequence. If that string is 74 characters long, then Python sees that as 74 separate bind values, each one character long.

>>> len(img)
74
>>> len((img,))
1

If you find it easier to read, you can also use a list literal:

cursor.execute('INSERT INTO images VALUES(?)', [img])

There is more than one way to do it.

1). A long statement:

>>> def print_something():
         print 'This is a really long line,', \
               'but we can make it across multiple lines.'

2). Using parenthesis:

>>> def print_something():
        print ('Wow, this also works?',
               'I never knew!')

3). Using \ again:

>>> x = 10
>>> if x == 10 or x > 0 or \
       x < 100:
       print 'True'

Quoting PEP8:

The preferred way of wrapping long lines is by using Python's implied line continuation inside parentheses, brackets and braces. If necessary, you can add an extra pair of parentheses around an expression, but sometimes using a backslash looks better. Make sure to indent the continued line appropriately. The preferred place to break around a binary operator is after the operator, not before it.

You're obviously looking for the Nullable Monad:

string result = new A().PropertyB.PropertyC.Value;

becomes

string result = from a in new A()
                from b in a.PropertyB
                from c in b.PropertyC
                select c.Value;

This returns null, if any of the nullable properties are null; otherwise, the value of Value.

class A { public B PropertyB { get; set; } }
class B { public C PropertyC { get; set; } }
class C { public string Value { get; set; } }

LINQ extension methods:

public static class NullableExtensions
{
    public static TResult SelectMany<TOuter, TInner, TResult>(
        this TOuter source,
        Func<TOuter, TInner> innerSelector,
        Func<TOuter, TInner, TResult> resultSelector)
        where TOuter : class
        where TInner : class
        where TResult : class
    {
        if (source == null) return null;
        TInner inner = innerSelector(source);
        if (inner == null) return null;
        return resultSelector(source, inner);
    }
}

You want a pointer to the first element, so;

static uint8_t l_matrix[10][20];

void test(){
   uint8_t *matrix_ptr = l_matrix[0]; //wrong idea 
}

As per the latest bootstrap v3.3.7 xs-offseting is allowed. See the documentation here bootstrap offseting. So you can use

<div class="col-xs-2 col-xs-offset-1">.col-xs-2 .col-xs-offset-1</div>

#include <iostream>
#include <type_traits>

using namespace std;

enum class A {
  a = 1,
  b = 69,
  c= 666
};

std::ostream& operator << (std::ostream& os, const A& obj)
{
   os << static_cast<std::underlying_type<A>::type>(obj);
   return os;
}

int main () {
  A a = A::c;
  cout << a << endl;
}

Variables have a type and a value.

• $var = "test" is a string that contain "test"
• $var2 = 24 is an integer vhose value is 24.

When you use these variables (in PHP), sometimes you don't have the good type. For example, if you do

if ($var == 1) {... do something ...}

PHP have to convert ("to cast") $var to integer. In this case, "$var == 1" is true because any non-empty string is casted to 1.

When using ===, you check that the value AND THE TYPE are equal, so "$var === 1" is false.

This is useful, for example, when you have a function that can return false (on error) and 0 (result) :

if(myFunction() == false) { ... error on myFunction ... }

This code is wrong as if myFunction() returns 0, it is casted to false and you seem to have an error. The correct code is :

if(myFunction() === false) { ... error on myFunction ... }

because the test is that the return value "is a boolean and is false" and not "can be casted to false".

Another Solution For Windows Users:

This uses Github as a bridge to get to Bitbucket, caused to the lack of publishing directly from the windows Sourcetree app.

1. Load your local repo into the Github desktop app.
2. Publish the repo as a private (for privacy - if desired) repo from the Github desktop app into your Github account.
3. Open your personal / team account in Bitbucket's website
4. Create a new Bitbucket repo by importing from Github.
5. Delete the repo in Github.

Once this is done, everything will be loaded into Bitbucket. Your local remotes will probably need to be configured to point to Bitbucket now.

Another solution is to use the query method:

import pandas as pd

from random import randint
df = pd.DataFrame({'A': [randint(1, 9) for x in xrange(10)],
                   'B': [randint(1, 9) * 10 for x in xrange(10)],
                   'C': [randint(1, 9) * 100 for x in xrange(10)]})
print df

   A   B    C
0  7  20  300
1  7  80  700
2  4  90  100
3  4  30  900
4  7  80  200
5  7  60  800
6  3  80  900
7  9  40  100
8  6  40  100
9  3  10  600

print df.query('B > 50 and C != 900')

   A   B    C
1  7  80  700
2  4  90  100
4  7  80  200
5  7  60  800

Now if you want to change the returned values in column A you can save their index:

my_query_index = df.query('B > 50 & C != 900').index

....and use .iloc to change them i.e:

df.iloc[my_query_index, 0] = 5000

print df

      A   B    C
0     7  20  300
1  5000  80  700
2  5000  90  100
3     4  30  900
4  5000  80  200
5  5000  60  800
6     3  80  900
7     9  40  100
8     6  40  100
9     3  10  600

Another option is to convert the YAML to JSON, then use jq to interact with the JSON representation either to extract information from it or edit it.

I wrote a simple bash script that contains this glue - see Y2J project on GitHub

Use Application.ActiveWorkbook.Path for just the path itself (without the workbook name) or Application.ActiveWorkbook.FullName for the path with the workbook name.

Executing a click via JavaScript has some behaviors of which you should be aware. If for example, the code bound to the onclick event of your element invokes window.alert(), you may find your Selenium code hanging, depending on the implementation of the browser driver. That said, you can use the JavascriptExecutor class to do this. My solution differs from others proposed, however, in that you can still use the WebDriver methods for locating the elements.

// Assume driver is a valid WebDriver instance that
// has been properly instantiated elsewhere.
WebElement element = driver.findElement(By.id("gbqfd"));
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();", element);

You should also note that you might be better off using the click() method of the WebElement interface, but disabling native events before instantiating your driver. This would accomplish the same goal (with the same potential limitations), but not force you to write and maintain your own JavaScript.

In SQL Server if you need only the hh:mi, you can use:

DECLARE @datetime datetime

SELECT @datetime = GETDATE()

SELECT RIGHT('0'+CAST(DATEPART(hour, @datetime) as varchar(2)),2) + ':' +
       RIGHT('0'+CAST(DATEPART(minute, @datetime)as varchar(2)),2)

You have to use Javascript Filereader for this. (Introduction into filereader-api: http://www.html5rocks.com/en/tutorials/file/dndfiles/)

Once the user have choose a image you can read the file-path of the chosen image and place it into your html.

Example:

<form id="form1" runat="server">
    <input type='file' id="imgInp" />
    <img id="blah" src="#" alt="your image" />
</form>

Javascript:

function readURL(input) {
    if (input.files && input.files[0]) {
        var reader = new FileReader();

        reader.onload = function (e) {
            $('#blah').attr('src', e.target.result);
        }

        reader.readAsDataURL(input.files[0]);
    }
}

$("#imgInp").change(function(){
    readURL(this);
});

Use

    import java.io.BufferedReader;
    import java.io.File;
    import java.io.FileInputStream;
    import java.io.IOException;
    import java.io.InputStreamReader;
    import java.io.UnsupportedEncodingException;     
    public class test {
    public static void main(String[] args){

    try {
        File fileDir = new File("PATH_TO_FILE");

        BufferedReader in = new BufferedReader(
           new InputStreamReader(new FileInputStream(fileDir), "UTF-8"));

        String str;

        while ((str = in.readLine()) != null) {
            System.out.println(str);
        }

                in.close();
        } 
        catch (UnsupportedEncodingException e) 
        {
            System.out.println(e.getMessage());
        } 
        catch (IOException e) 
        {
            System.out.println(e.getMessage());
        }
        catch (Exception e)
        {
            System.out.println(e.getMessage());
        }
    }
}

You need to put UTF-8 in quotes

If you want to change whether it highlights the best fitting possibility, use:

Ctrl + Alt + Space

Query to achieve your requirment

SELECT id,GROUP_CONCAT(text SEPARATOR ' ') AS text FROM table_name group by id;

I was looking for the same and this may also work

p.Wages.all.A_MEAN <- Wages.all %>%
                  group_by(`Career Cluster`, Year)%>%
                  summarize(ANNUAL.MEAN.WAGE = mean(A_MEAN))

names(p.Wages.all.A_MEAN) [1] "Career Cluster" "Year" "ANNUAL.MEAN.WAGE"

p.Wages.all.a.mean <- ggplot(p.Wages.all.A_MEAN, aes(Year, ANNUAL.MEAN.WAGE , color= `Career Cluster`))+
                  geom_point(aes(col=`Career Cluster` ), pch=15, size=2.75, alpha=1.5/4)+
                  theme(axis.text.x = element_text(color="#993333",  size=10, angle=0)) #face="italic",
p.Wages.all.a.mean

You can always do

('0' + deg).slice(-2)

See slice():

You can also use negative numbers to select from the end of an array

Hence

('0' + 11).slice(-2) // '11'
('0' + 4).slice(-2)  // '04'

For ease of access, you could of course extract it to a function, or even extend Number with it:

Number.prototype.pad = function(n) {
    return new Array(n).join('0').slice((n || 2) * -1) + this;
}

Which will allow you to write:

c += deg.pad() + '° '; // "04° "

The above function pad accepts an argument specifying the length of the desired string. If no such argument is used, it defaults to 2. You could write:

deg.pad(4) // "0045"

Note the obvious drawback that the value of n cannot be higher than 11, as the string of 0's is currently just 10 characters long. This could of course be given a technical solution, but I did not want to introduce complexity in such a simple function. (Should you elect to, see alex's answer for an excellent approach to that).

Note also that you would not be able to write 2.pad(). It only works with variables. But then, if it's not a variable, you'll always know beforehand how many digits the number consists of.

figure;
plot(something);

or

figure(2);
plot(something);
...
figure(3);
plot(something else);
...

etc.

Unless you resize up, you cannot do this with raster graphics.

What you can do with good filtering and smoothing is to resize without losing any noticable quality.

You can also alter the DPI metadata of the image (assuming it has some) which will keep exactly the same pixel count, but will alter how image editors think of it in 'real-world' measurements.

And just to cover all bases, if you really meant just the file size of the image and not the actual image dimensions, I suggest you look at a lossless encoding of the image data. My suggestion for this would be to resave the image as a .png file (I tend to use paint as a free transcoder for images in windows. Load image in paint, save as in the new format)

Single statement that works with trailing slash. If you are using IE11 you'll have to polyfill the filter function.

var name = window.location.pathname
        .split("/")
        .filter(function (c) { return c.length;})
        .pop();

In Ubuntu for install imap use

sudo apt-get install php-imap

Ubuntu 14.04 and above use

sudo apt-get install php5-imap

And imap by default not enabled by PHP so use this command to enable imap extension

sudo php5enmod imap

Then restart your Apache

sudo service apache2 restart

I had issues getting the above code to work within cookie.js. The following code managed to create the correct timestamp for the cookie expiration in my instance.

var inFifteenMinutes = new Date(new Date().getTime() + 15 * 60 * 1000);

This was from the FAQs for Cookie.js

Works for WebView but seems to fail on URL.openStream(). So you need to distinguish file:// protocols and handle them via AssetManager as suggested.

You can.

package test;

public class Test {
    public static void main(String[] args) {
        B b = new B();
    }
}

class B {
  // Essentially package-private - cannot be accessed anywhere else but inside the `test` package
}

As @Didier said, you can change your delimiter to something other than /:

grep -rl $oldstring /path/to/folder | xargs sed -i s@$oldstring@$newstring@g

Paul Dixon's answer worked brilliantly for me. To add to this, here are some things I observed for those interested in using REGEXP:

To Accomplish multiple LIKE filters with Wildcards:

 SELECT * FROM fiberbox WHERE field LIKE '%1740 %'
                           OR field LIKE '%1938 %'
                           OR field LIKE '%1940 %';  

Use REGEXP Alternative:

 SELECT * FROM fiberbox WHERE field REGEXP '1740 |1938 |1940 ';

Values within REGEXP quotes and between the | (OR) operator are treated as wildcards. Typically, REGEXP will require wildcard expressions such as (.*)1740 (.*) to work as %1740 %.

If you need more control over placement of the wildcard, use some of these variants:

To Accomplish LIKE with Controlled Wildcard Placement:

SELECT * FROM fiberbox WHERE field LIKE '1740 %'
                          OR field LIKE '%1938 '
                          OR field LIKE '%1940 % test';  

Use:

SELECT * FROM fiberbox WHERE field REGEXP '^1740 |1938 $|1940 (.*) test';

• Placing ^ in front of the value indicates start of the line.

• Placing $ after the value indicates end of line.

• Placing (.*) behaves much like the % wildcard.

• The . indicates any single character, except line breaks. Placing . inside () with * (.*) adds a repeating pattern indicating any number of characters till end of line.

There are more efficient ways to narrow down specific matches, but that requires more review of Regular Expressions. NOTE: Not all regex patterns appear to work in MySQL statements. You'll need to test your patterns and see what works.

Finally, To Accomplish Multiple LIKE and NOT LIKE filters:

SELECT * FROM fiberbox WHERE field LIKE '%1740 %'
                          OR field LIKE '%1938 %'
                          OR field NOT LIKE '%1940 %'
                          OR field NOT LIKE 'test %'
                          OR field = '9999';

Use REGEXP Alternative:

SELECT * FROM fiberbox WHERE field REGEXP '1740 |1938 |^9999$'
                          OR field NOT REGEXP '1940 |^test ';

OR Mixed Alternative:

SELECT * FROM fiberbox WHERE field REGEXP '1740 |1938 '
                          OR field NOT REGEXP '1940 |^test '
                          OR field NOT LIKE 'test %'
                          OR field = '9999';

Notice I separated the NOT set in a separate WHERE filter. I experimented with using negating patterns, forward looking patterns, and so on. However, these expressions did not appear to yield the desired results. In the first example above, I use ^9999$ to indicate exact match. This allows you to add specific matches with wildcard matches in the same expression. However, you can also mix these types of statements as you can see in the second example listed.

Regarding performance, I ran some minor tests against an existing table and found no differences between my variations. However, I imagine performance could be an issue with bigger databases, larger fields, greater record counts, and more complex filters.

As always, use logic above as it makes sense.

If you want to learn more about regular expressions, I recommend www.regular-expressions.info as a good reference site.

Request.Redirect(url,false);

false indicates whether execution of current page should terminate.

This should work:

txtfarmersize = Convert.ToInt32(reader["farmsize"]);

You missed out omniORB. This is a pretty full CORBA implementation, so you can also use it to talk to other languages that have CORBA support.

I believe you can use this one:

new Date().toLocaleDateString();

Which can accept parameters for the locale:

new Date().toLocaleDateString("en-us");
new Date().toLocaleDateString("he-il");

I see it is supported by chrome, IE, edge, although results may vary it does a pretty good job for me.

I might get beat up for my answer but here goes anyway:

I would simply write

string s = ""
if (myObj != null) {
   x = myObj.toString();
}

Is there a payoff in terms of performance for using the ternary operator? I don't know off the top of my head.

And clearly, as someone above mentioned, you can put this behavior into a method such as safeString(myObj) that allows for reuse.

select to_char(tran_datetime,'HH24') from test;

TO_CHAR(tran_datetime,'HH24')

To do this you can come up with a width you feel is ok for both buttons and then create a custom class with the width and add it to your buttons like so:

CSS

.custom {
    width: 78px !important;
}

I can then use this class and add it to the buttons like so:

<p><button href="#" class="btn btn-primary custom">Save</button></p>
<p><button href="#" class="btn btn-success custom">Download</button></p>

Demo: http://jsfiddle.net/yNsxU/

You can take that custom class you create and place it inside your own stylesheet, which you load after the bootstrap stylesheet. We do this because any changes you place inside the bootstrap stylesheet might get accidentally lost when you update the framework, we also want your changes to take precedence over the default values.

I had the same problem, and didn´t want to rewrite the code, so I wrote a function to modify the code and create the inline declarated events:

function compile(qSel){
    var matches = [];
    var match = null;
    var c = 0;

    var html = $(qSel).html();
    var pattern = /(<(.*?)on([a-zA-Z]+)\s*=\s*('|")(.*)('|")(.*?))(>)/mg;

    while (match = pattern.exec(html)) {
        var arr = [];
        for (i in match) {
            if (!isNaN(i)) {
                arr.push(match[i]);
            }
        }
        matches.push(arr);
    }
    var items_with_events = [];
    var compiledHtml = html;

    for ( var i in matches ){
        var item_with_event = {
            custom_id : "my_app_identifier_"+i,
            code : matches[i][5],
            on : matches[i][3],
        };
        items_with_events.push(item_with_event);
        compiledHtml = compiledHtml.replace(/(<(.*?)on([a-zA-Z]+)\s*=\s*('|")(.*)('|")(.*?))(>)/m, "<$2 custom_id='"+item_with_event.custom_id+"' $7 $8");
    }

    $(qSel).html(compiledHtml);

    for ( var i in items_with_events ){
        $("[custom_id='"+items_with_events[i].custom_id+"']").bind(items_with_events[i].on, function(){
            eval(items_with_events[i].code);
        });
    }
}

$(document).ready(function(){
    compile('#content');
})

This should remove all inline events from the selected node, and recreate them with jquery instead.

There are workarounds but no clean/short/sweet way to do it with streams and to be honest, you would probably be better off with:

int idx = 0;
for (Param p : params) query.bind(idx++, p);

Or the older style:

for (int idx = 0; idx < params.size(); idx++) query.bind(idx, params.get(idx));

It's because your enum is not the standard library enum module. You probably have the package enum34 installed.

One way check if this is the case is to inspect the property enum.__file__

import enum
print(enum.__file__)  
# standard library location should be something like 
# /usr/local/lib/python3.6/enum.py

Since python 3.6 the enum34 library is no longer compatible with the standard library. The library is also unnecessary, so you can simply uninstall it.

pip uninstall -y enum34

If you need the code to run on python versions both <=3.4 and >3.4, you can try having enum-compat as a requirement. It only installs enum34 for older versions of python without the standard library enum.

Here is a CSV action result I wrote that takes a DataTable and converts it into CSV. You can return this from your view and it will prompt the user to download the file. You should be able to convert this easily into a List compatible form or even just put your list into a DataTable.

        protected string CleanCSVString(string input)
        {
            string output = "\"" + input.Replace("\"", "\"\"").Replace("\r\n", " ").Replace("\r", " ").Replace("\n", "") + "\"";
            return output;
        }
    }
}

This works without needing jQuery:

var textArea = document.getElementById("my-text-area");
var arrayOfLines = textArea.value.split("\n"); // arrayOfLines is array where every element is string of one line

For me a simple

exit

works. This is from within the screen session.

Since it is really a formatting issue when displaying the date (e.g. displays in local time), I like to use the new(ish) Intl.DateTimeFormat object to perform the formatting as it is more explicit and provides more output options:

const dateOptions = { timeZone: 'UTC', month: 'long', day: 'numeric', year: 'numeric' };

const dateFormatter = new Intl.DateTimeFormat('en-US', dateOptions);
const dateAsFormattedString = dateFormatter.format(new Date('2019-06-01T00:00:00.000+00:00'));

console.log(dateAsFormattedString) // "June 1, 2019"

As shown, by setting the timeZone to 'UTC' it will not perform local conversions. As a bonus, it also allows you to create more polished outputs. You can read more about the Intl.DateTimeFormat object from Mozilla - Intl.DateTimeFormat.

Edit:

The same functionality can be achieved without creating a new Intl.DateTimeFormat object. Simply pass the locale and date options directly into the toLocaleDateString() function.

const dateOptions = { timeZone: 'UTC', month: 'long', day: 'numeric', year: 'numeric' };
const myDate = new Date('2019-06-01T00:00:00.000+00:00');
today.toLocaleDateString('en-US', dateOptions); // "June 1, 2019"

After learning what it is all about, I thought to write a hopefully simpler explanation via analogy:

Summary: What is a hashcode?

• It's a fingerprint. We can use this finger print to identify people of interest.

Read below for more details:

Think of a Hashcode as us trying to To Uniquely Identify Someone

I am a detective, on the look out for a criminal. Let us call him Mr Cruel. (He was a notorious murderer when I was a kid -- he broke into a house kidnapped and murdered a poor girl, dumped her body and he's still out on the loose - but that's a separate matter). Mr Cruel has certain peculiar characteristics that I can use to uniquely identify him amongst a sea of people. We have 25 million people in Australia. One of them is Mr Cruel. How can we find him?

Bad ways of Identifying Mr Cruel

Apparently Mr Cruel has blue eyes. That's not much help because almost half the population in Australia also has blue eyes.

Good ways of Identifying Mr Cruel

What else can i use? I know: I will use a fingerprint!

Advantages:

• It is really really hard for two people to have the same finger print (not impossible, but extremely unlikely).
• Mr Cruel's fingerprint will never change.
• Every single part of Mr Cruel's entire being: his looks, hair colour, personality, eating habits etc must (ideally) be reflected in his fingerprint, such that if he has a brother (who is very similar but not the same) - then both should have different finger prints. I say "should" because we cannot guarantee 100% that two people in this world will have different fingerprints.
• But we can always guarantee that Mr Cruel will always have the same finger print - and that his fingerprint will NEVER change.

The above characteristics generally make for good hash functions.

So what's the deal with 'Collisions'?

So imagine if I get a lead and I find someone matching Mr Cruel's fingerprints. Does this mean I have found Mr Cruel?

........perhaps! I must take a closer look. If i am using SHA256 (a hashing function) and I am looking in a small town with only 5 people - then there is a very good chance I found him! But if I am using MD5 (another famous hashing function) and checking for fingerprints in a town with +2^1000 people, then it is a fairly good possibility that two entirely different people might have the same fingerprint.

So what is the benefit of all this anyways?

The only real benefit of hashcodes is if you want to put something in a hash table - and with hash tables you'd want to find objects quickly - and that's where the hash code comes in. They allow you to find things in hash tables really quickly. It's a hack that massively improves performance, but at a small expense of accuracy.

So let's imagine we have a hash table filled with people - 25 million suspects in Australia. Mr Cruel is somewhere in there..... How can we find him really quickly? We need to sort through them all: to find a potential match, or to otherwise acquit potential suspects. You don't want to consider each person's unique characteristics because that would take too much time. What would you use instead? You'd use a hashcode! A hashcode can tell you if two people are different. Whether Joe Bloggs is NOT Mr Cruel. If the prints don't match then you know it's definitely NOT Mr Cruel. But, if the finger prints do match then depending on the hash function you used, chances are already fairly good you found your man. But it's not 100%. The only way you can be certain is to investigate further: (i) did he/she have an opportunity/motive, (ii) witnesses etc etc.

When you are using computers if two objects have the same hash code value, then you again need to investigate further whether they are truly equal. e.g. You'd have to check whether the objects have e.g. the same height, same weight etc, if the integers are the same, or if the customer_id is a match, and then come to the conclusion whether they are the same. this is typically done perhaps by implementing an IComparer or IEquality interfaces.

Key Summary

So basically a hashcode is a finger print.

1. Two different people/objects can theoretically still have the same fingerprint. Or in other words. If you have two fingerprints that are the same.........then they need not both come from the same person/object.
2. Buuuuuut, the same person/object will always return the same fingerprint.
3. Which means that if two objects return different hash codes then you know for 100% certainty that those objects are different.

It takes a good 3 minutes to get your head around the above. Perhaps read it a few times till it makes sense. I hope this helps someone because it took a lot of grief for me to learn it all!

tried all proposed solutions, all seem to have issues of their own.

If you actually look into the Orchestrator source, particularly the .start() implementation you will see that if the last parameter is a function it will treat it as a callback.

I wrote this snippet for my own tasks:

  gulp.task( 'task1', () => console.log(a) )
  gulp.task( 'task2', () => console.log(a) )
  gulp.task( 'task3', () => console.log(a) )
  gulp.task( 'task4', () => console.log(a) )
  gulp.task( 'task5', () => console.log(a) )

  function runSequential( tasks ) {
    if( !tasks || tasks.length <= 0 ) return;

    const task = tasks[0];
    gulp.start( task, () => {
        console.log( `${task} finished` );
        runSequential( tasks.slice(1) );
    } );
  }
  gulp.task( "run-all", () => runSequential([ "task1", "task2", "task3", "task4", "task5" ));

There is no such functionality but you can use a temporary file by File.createTempFile().

File temp = File.createTempFile(prefix, suffix);
// tell system to delete it when vm terminates.
temp.deleteOnExit();

You can certainly extract that part of a string and that's a great way to parse out data. Regular expression syntax varies a lot so you need to reference the help file for the regex you're using. You might try a regular expression like:

[0-9]+ *[a-zA-Z]+,([0-9]+) *[a-zA-Z]+,[0-9]+ *[a-zA-Z]+

If your regex program can do string replacement then replace the entire string with the result you want and you can easily use that result.

You didn't mention if you're using bash or some other shell. That would help get better answers when asking for help.

Off the top of my head:

1. The element must be block-level, e.g. display: block or display: table
2. The element must not float
3. The element must not have a fixed or absolute position¹

Off the top of other people's heads:

4. The element must have a width that is not auto²

Note that all of these conditions must be true of the element being centered for it to work.

¹ _{There is one exception to this: if your fixed or absolutely positioned element has left: 0; right: 0, it will center with auto margins.}

² _{Technically, margin: 0 auto does work with an auto width, but the auto width takes precedence over the auto margins, and the auto margins are zeroed out as a result, making it seem as though they "don't work".}

This thread might be dead, but StyledMarker is available for API v3. Just bind the color change you want to the correct DOM event using the addDomListener() method. This example is pretty close to what you want to do. If you look at the page source, change:

google.maps.event.addDomListener(document.getElementById("changeButton"),"click",function() {
  styleIcon.set("color","#00ff00");
  styleIcon.set("text","Go");
});

to something like:

google.maps.event.addDomListener("mouseover",function() {
  styleIcon.set("color","#00ff00");
  styleIcon.set("text","Go");
});

That should be enough to get you moving along.

The Wikipedia page on DOM Events will also help you target the event that you want to capture on the client-side.

Good luck (if you still need it)

for i in range(100):
try:
  #Your code here
  break
except:
  continue

This one worked for me.

You can find some technical comparison on npmcompare

Comparing browserify vs. grunt vs. gulp vs. webpack

As you can see webpack is very well maintained with a new version coming out every 4 days on average. But Gulp seems to have the biggest community of them all (with over 20K stars on Github) Grunt seems a bit neglected (compared to the others)

So if need to choose one over the other i would go with Gulp

What is the current approach to make a custom AuthorizeAttribute

Easy: don't create your own AuthorizeAttribute.

For pure authorization scenarios (like restricting access to specific users only), the recommended approach is to use the new authorization block: https://github.com/aspnet/MusicStore/blob/1c0aeb08bb1ebd846726232226279bbe001782e1/samples/MusicStore/Startup.cs#L84-L92

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.Configure<AuthorizationOptions>(options =>
        {
            options.AddPolicy("ManageStore", policy => policy.RequireClaim("Action", "ManageStore"));
        });
    }
}

public class StoreController : Controller
{
    [Authorize(Policy = "ManageStore"), HttpGet]
    public async Task<IActionResult> Manage() { ... }
}

For authentication, it's best handled at the middleware level.

What are you trying to achieve exactly?

Use the REPLACE function.

eg: SELECT REPLACE ('t?es?t', '?', 'w');

In addition to Boaz's answer ....

@UniqueConstraint allows you to name the constraint, while @Column(unique = true) generates a random name (e.g. UK_3u5h7y36qqa13y3mauc5xxayq).

Sometimes it can be helpful to know what table a constraint is associated with. E.g.:

@Table(
   name = "product_serial_group_mask", 
   uniqueConstraints = {
      @UniqueConstraint(
          columnNames = {"mask", "group"},
          name="uk_product_serial_group_mask"
      )
   }
)

You have to declare your functions before main()

(or declare the function prototypes before main())

As it is, the compiler sees my_print (my_string); in main() as a function declaration.

Move your functions above main() in the file, or put:

void my_print (char *);
void my_print2 (char *);

Above main() in the file.

In the form closest to your original:

import datetime

def UtcNow():
    now = datetime.datetime.utcnow()
    return now

If you need to know the number of seconds from 1970-01-01 rather than a native Python datetime, use this instead:

return (now - datetime.datetime(1970, 1, 1)).total_seconds()

Python has naming conventions that are at odds with what you might be used to in Javascript, see PEP 8. Also, a function that simply returns the result of another function is rather silly; if it's just a matter of making it more accessible, you can create another name for a function by simply assigning it. The first example above could be replaced with:

utc_now = datetime.datetime.utcnow

let imageView: UIImageView = //this is your existing imageView

let imageViewHeight: CGFloat = imageView.frame.height

let imageViewWidth: CGFloat = imageView.frame.width

execl("/home/vlc", 
  "/home/vlc", "/home/my movies/the movie i want to see.mkv", 
  (char*) NULL);

You need to specify all arguments, included argv[0] which isn't taken from the executable.

Also make sure the final NULL gets cast to char*.

Details are here: http://pubs.opengroup.org/onlinepubs/9699919799/functions/exec.html

agf's bytearray solution is workable, but if you find yourself needing to build up more complicated packets using datatypes other than bytes, you can try struct.pack(). http://docs.python.org/release/3.1.3/library/struct.html

You can also use /dev/urandom:

grep -m1 -ao '[0-9]' /dev/urandom | sed s/0/10/ | head -n1

I tried all the proposals to fix the render performance problem in my phonegap app. But nothing realy worked.

Finally, after a whole day of searching, I made it. I set within the tag (not the tag) of my AndroidManifest

<application android:hardwareAccelerated="false" ...

Now the app behaves in the same fast way as my webbrowser. Seems like, if hardware acceleration is not always the best feature...

The detailed problem I had: https://stackoverflow.com/a/24467920/3595386

From: http://web.archive.org/web/20090221144611/http://faqts.com/knowledge_base/view.phtml/aid/1/fid/40

1. Speed. There is a difference between the two, but speed-wise it should be irrelevant which one you use. echo is marginally faster since it doesn't set a return value if you really want to get down to the nitty gritty.

2. Expression. print() behaves like a function in that you can do: $ret = print "Hello World"; And $ret will be 1. That means that print can be used as part of a more complex expression where echo cannot. An example from the PHP Manual:

$b ? print "true" : print "false";

print is also part of the precedence table which it needs to be if it is to be used within a complex expression. It is just about at the bottom of the precedence list though. Only , AND OR XOR are lower.

3. Parameter(s). The grammar is: echo expression [, expression[, expression] ... ] But echo ( expression, expression ) is not valid. This would be valid: echo ("howdy"),("partner"); the same as: echo "howdy","partner"; (Putting the brackets in that simple example serves no purpose since there is no operator precedence issue with a single term like that.)

So, echo without parentheses can take multiple parameters, which get concatenated:

   echo  "and a ", 1, 2, 3;   // comma-separated without parentheses
   echo ("and a 123");        // just one parameter with parentheses

print() can only take one parameter:

   print ("and a 123");
   print  "and a 123";

I notice you have some C++ questions in your profile. If you understand the concept of multiple-inheritance from C++ (referring to classes that inherit characteristics from more than one other class), Java does not allow this, but it does have keyword interface, which is sort of like a pure virtual class in C++. As mentioned by lots of people, you extend a class (and you can only extend from one), and you implement an interface -- but your class can implement as many interfaces as you like.

Ie, these keywords and the rules governing their use delineate the possibilities for multiple-inheritance in Java (you can only have one super class, but you can implement multiple interfaces).

I am using this code for my project

$(window).scroll ( function() {
    if ($(document).scrollTop() > 50) {
        document.getElementById('your-div').style.height = '100px'; //For eg
    } else {
        document.getElementById('your-div').style.height = '150px';
    }    
}
);

Probably this will help

Easiest way I find for multiple searches is to pipe them all (probably heavier CPU use) but for your example user:

Get-EventLog -LogName Security | where {$_.UserName -notlike "*user1"} |  where {$_.UserName -notlike "*user2"}

You can pass the parent´s stdio to the child process if that´s what you want:

require('child_process').execSync(
    'rsync -avAXz --info=progress2 "/src" "/dest"',
    {stdio: 'inherit'}
);

string tests = "abc][rfd][5][,][.";
string[] reslts = tests.Split(new char[] { ']', '[' }, StringSplitOptions.RemoveEmptyEntries);

First, get all the elements

const getAllFormElements = element => Array.from(element.elements).filter(tag => ["select", "textarea", "input"].includes(tag.tagName.toLowerCase()));

Second, do something with them

const pageFormElements = getAllFormElements(document.body);
console.log(pageFormElements);

If you want to use a form, rather than the entire body of the page, you can do it like this

const pageFormElements = getAllFormElements(document.getElementById("my-form"));
console.log(formElements);

You can use ElementRef as shown below,

DEMO : https://plnkr.co/edit/XZwXEh9PZEEVJpe0BlYq?p=preview check browser's console.

import { Directive,Input,Outpu,ElementRef,Renderer} from '@angular/core';

@Directive({
  selector:"[move]",
  host:{
    '(click)':"show()"
  }
})

export class GetEleDirective{

  constructor(private el:ElementRef){

  }
  show(){
    console.log(this.el.nativeElement);

    console.log('height---' + this.el.nativeElement.offsetHeight);  //<<<===here
    console.log('width---' + this.el.nativeElement.offsetWidth);    //<<<===here
  }
}

Same way you can use it within component itself wherever you need it.

When paging is turned on,you could use these code.

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
{
    self.lastPage = self.currentPage;
    CGFloat pageWidth = _mainScrollView.frame.size.width;
    self.currentPage = floor((_mainScrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1;
    if (self.lastPage < self.currentPage) {
        //go right
        NSLog(@"right");
    }else if(self.lastPage > self.currentPage){
        //go left
        NSLog(@"left");
    }else if (self.lastPage == self.currentPage){
        //same page
        NSLog(@"same page");
    }
}

For me the problem was I had to use /usr/bin/php-cgi command instead of just /usr/bin/php

php-cgi is the command run when accessed thru web browser.

php is the CLI command line command.

Not sure why php cli is not working, but running with php-cgi instead fixed the problem for me.
