I was facing a time offset of -1hour and 4min

Restarting Docker itself fixed the issue for me.

To set the timezone in general:

1. ssh into your container: docker exec -it my_website_name bash

2. run dpkg-reconfigure tzdata

3. run date

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setStyle(DialogFragment.STYLE_NORMAL,
             android.R.style.Theme_Black_NoTitleBar_Fullscreen);
}

You don't want to take care of normalizing your data in a view - what if the user changes the data that gets submitted? Instead you could take care of it in the model using the before_save (or the before_validation) callback. Here's an example of the relevant code for a model like yours:

class Place < ActiveRecord::Base   before_save do |place|     place.city = place.city.downcase.titleize     place.country = place.country.downcase.titleize   end end 

You can also check out the Ruby on Rails guide for more info.

To answer you question more directly, something like this would work:

<%= f.text_field :city, :value => (f.object.city ? f.object.city.titlecase : '') %>   

This just means if f.object.city exists, display the titlecase version of it, and if it doesn't display a blank string.

Why reinvent the wheel? RandomStringUtils from Apache Commons has functions to which you can specify the character set from which characters are generated. You can take what you need to your app:

http://kickjava.com/src/org/apache/commons/lang/RandomStringUtils.java.htm

This way doesn't work now:

 btn.titleLabel?.font = UIFont(name: "Helvetica", size:12)

This works:

 btn.titleLabel?.font = UIFont.init(name: "Helvetica", size:12)

I accomplished the above using relative positioning and floating to the right.

HTML code:

<div class="clearfix">                          
    <div class="outer-div">
        <div class="inner-div">
            <div class="floating-div">Float 1</div>
            <div class="floating-div">Float 2</div>
            <div class="floating-div">Float 3</div>
        </div>
    </div>
</div>

CSS:

.outer-div { position: relative; float: right; right: 50%; }
.inner-div { position: relative; float: right; right: -50%; }
.floating-div { float: left; border: 1px solid red; margin: 0 1.5em; }

.clearfix:before,
.clearfix:after { content: " "; display: table; }
.clearfix:after { clear: both; }
.clearfix { *zoom: 1; }

This will work in IE8 and up, but not earlier (surprise, surprise!)

I do not recall the source of this method unfortunately, so I cannot give credit to the original author. If anybody else knows, please post the link!

You are importing the module datetime, which doesn't have a strptime function.

That module does have a datetime object with that method though:

import datetime
dtDate = datetime.datetime.strptime(sDate, "%m/%d/%Y")

Alternatively you can import the datetime object from the module:

from datetime import datetime
dtDate = datetime.strptime(sDate, "%m/%d/%Y")

Note that the strptime method was added in python 2.5; if you are using an older version use the following code instead:

import datetime, time
dtDate = datetime.datetime(*time.strptime(sDate, "%m/%d/%Y")[:6])

ColumnNames is a property of type List<String> so when you are setting up you need to pass a List<String> in the Returns call as an argument (or a func which return a List<String>)

But with this line you are trying to return just a string

input.SetupGet(x => x.ColumnNames).Returns(temp[0]);

which is causing the exception.

Change it to return whole list:

input.SetupGet(x => x.ColumnNames).Returns(temp);

I have been searching for this same answer all morning and have pretty much found out that it's probably impossible to verify if every email address you ever need to check actually exists at the time you need to verify it. So as a work around, I kind of created a simple PHP script to verify that the email address is formatted correct and it also verifies that the domain name used is correct as well.

GitHub here https://github.com/DukeOfMarshall/PHP---JSON-Email-Verification/tree/master

Try to make your javascript unobtrusive :

• you should use a real link in href attribute
• and add a listener on click event to handle ajax

You can run Rake tasks from your shell by running:

rake task_name

To run from from Ruby (e.g., in the Rails console or another Rake task):

Rake::Task['task_name'].invoke

To run multiple tasks in the same namespace with a single task, create the following new task in your namespace:

task :runall => [:iqmedier, :euroads, :mikkelsen, :orville] do
  # This will run after all those tasks have run
end

I've just noticed that the answer that I upvoted and commented on is ambiguous. So the following is exactly what worked for me. I'm currently on Moment 2.26.0 and TS 3.8.3:

In code:

import moment from 'moment';

In TS config:

{
  "compilerOptions": {
    "esModuleInterop": true,
    ...
  }
}

I am building for both CommonJS and EMS so this config is imported into other config files.

The insight comes from this answer which relates to using Express. I figured it was worth adding here though, to help anyone who searches in relation to Moment.js, rather than something more general.

Here is the link for installation details: http://php.net/manual/en/mysqli.installation.php

If you are using Windows or Linux:
- The MySQLi extension is automatically installed in most cases, when PHP & MySQL package is installed.

Do a readline at the end (it's the "forma cochina", like we say in Colombia, but it works):

static void Main(string[] args)
{
    .
    .
    .
    String temp = Console.ReadLine();
}

function saveAs(uri, filename) {
    var link = document.createElement('a');
    if (typeof link.download === 'string') {
        document.body.appendChild(link); // Firefox requires the link to be in the body
        link.download = filename;
        link.href = uri;
        link.click();
        document.body.removeChild(link); // remove the link when done
    } else {
        location.replace(uri);
    }
}

I often use something similar to this:

import os
DATA_DIR = os.path.abspath(os.path.join(os.path.dirname(__file__), 'datadir'))

# if you have more paths to set, you might want to shorten this as
here = lambda x: os.path.abspath(os.path.join(os.path.dirname(__file__), x))
DATA_DIR = here('datadir') 

pathjoin = os.path.join
# ...
# later in script
for fn in os.listdir(DATA_DIR):
    f = open(pathjoin(DATA_DIR, fn))
    # ...

The variable

__file__

holds the file name of the script you write that code in, so you can make paths relative to script, but still written with absolute paths. It works quite well for several reasons:

• path is absolute, but still relative
• the project can still be deployed in a relative container

But you need to watch for platform compatibility - Windows' os.pathsep is different than UNIX.

After wrestling with this problem today my opinion is this: BEGIN...END brackets code just like {....} does in C languages, e.g. code blocks for if...else and loops

GO is (must be) used when succeeding statements rely on an object defined by a previous statement. USE database is a good example above, but the following will also bite you:

alter table foo add bar varchar(8);
-- if you don't put GO here then the following line will error as it doesn't know what bar is.
update foo set bar = 'bacon';
-- need a GO here to tell the interpreter to execute this statement, otherwise the Parser will lump it together with all successive statements.

It seems to me the problem is this: the SQL Server SQL Parser, unlike the Oracle one, is unable to realise that you're defining a new symbol on the first line and that it's ok to reference in the following lines. It doesn't "see" the symbol until it encounters a GO token which tells it to execute the preceding SQL since the last GO, at which point the symbol is applied to the database and becomes visible to the parser.

Why it doesn't just treat the semi-colon as a semantic break and apply statements individually I don't know and wish it would. Only bonus I can see is that you can put a print() statement just before the GO and if any of the statements fail the print won't execute. Lot of trouble for a minor gain though.

I know I'm a little late to the party, but I did want to throw some interjections. (I would have commented but not enough reputation points yet, so, here's a full answer).

This requires the latest version of VS Code, Azure Repo Extention, and Git to be installed.

Anyone looking to use the new VS Code (or using the preview like myself), when you go to the Settings (Still File -> Preferences -> Settings or CTRL+, ) you'll be looking under User Settings -> Extensions -> Azure Repos.

Then under Tfvc: Location you can paste the location of the executable.

For 2017 it'll be

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\TF.exe

Or for 2019 (Preview)

C:\Program Files (x86)\Microsoft Visual Studio\2019\Preview\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\TF.exe

After adding the location, I closed my VS Code (not sure if this was needed) and went my git repo to copy the git URL.

After that, went back into VS Code went to the Command Palette (View -> Command Palette or CTRL+Shift+P) typed Git: Clone pasted my repo:

Selected the location for the repo to be stored. Next was an error that popped up. I proceeded to follow this video which walked me through clicking on the Team button with the exclamation mark on the bottom of your VS Code Screen

Then chose the new method of authentication

Copy by using CTRL+C and then press enter. Your browser will launch a page where you'll enter the code you copied (CTRL+V).

Click Continue

Log in with your Microsoft Credentials and you should see a change on the bottom bar of VS Code.

Cheers!

One liner:

diff = lambda l1,l2: [x for x in l1 if x not in l2]
diff(A,B)
diff(B,A)

Or:

diff = lambda l1,l2: filter(lambda x: x not in l2, l1)
diff(A,B)
diff(B,A)

From my limited experience, I would say that the following two scenario could cause response status code: 0, keep in mind; their could be more, but I know of those two:

• your connection maybe responding slowly.
• or maybe the the back-end server is not available.

the thing is, status: 0 is slightly generic, and their could be more use cases that trigger an empty response body.

If its calling spring boot service. you can handle it using below code.

@Bean
public WebMvcConfigurer corsConfigurer() {
    return new WebMvcConfigurerAdapter() {
        @Override
        public void addCorsMappings(CorsRegistry registry) {
            registry.addMapping("/**")
                    .allowedOrigins("*")
                    .allowedMethods("GET", "POST", "PUT", "DELETE", "HEAD", "OPTIONS")
                    .allowedHeaders("*", "Access-Control-Allow-Headers", "origin", "Content-type", "accept", "x-requested-with", "x-requested-by") //What is this for?
                    .allowCredentials(true);
        }
    };
}

It generally comes to mind that you have set up two-factor authentication, after a few password trials and maybe a password reset. So, how can we git clone a private repository using two-factor authentication? It is simple, using access tokens.

How to Authenticate Git using Access Tokens

1. Go to https://github.com/settings/tokens
2. Click Generate New Token button on top right.
3. Give your token a descriptive name.
4. Set all required permissions for the token.
5. Click Generate token button at the bottom.
6. Copy the generated token to a safe place.
7. Use this token instead of password when you use git clone.

Wow, it works!

For a unique column, use this:

INSERT OR REPLACE INTO table () values();

For more information, see: sqlite.org/lang_insert

This is a highly inefficient way of doing it. You can use the merge statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.

MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
  UPDATE SET l.studName = s.studName
   WHERE l.studName != s.studName
WHEN NOT MATCHED THEN 
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)

Make sure you commit, once completed, in order to be able to see this in the database.

To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.

It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.

However, as I say this will not be as efficient as merge.

declare

   cursor c_data is
    select b.rowid as rid, a.studId, a.studName
      from student a
      left outer join studLoad b
        on a.studId = b.studId
       and a.studName <> b.studName
           ;

   type t__data is table of c_data%rowtype index by binary_integer;
   t_data t__data;

begin

   open c_data;
   loop
      fetch c_data bulk collect into t_data limit 10000;

      exit when t_data.count = 0;

      for idx in t_data.first .. t_data.last loop
         if t_data(idx).rid is null then
            insert into studLoad (studId, studName)
            values (t_data(idx).studId, t_data(idx).studName);
         else
            update studLoad
               set studName = t_data(idx).studName
             where rowid = t_data(idx).rid
                   ;
         end if;
      end loop;

   end loop;
   close c_data;

end;

You don't need --header "Content-Length: $LENGTH".

curl --request POST --data-binary "@template_entry.xml" $URL

Note that GET request does not support content body widely.

Also remember that POST request have 2 different coding schema. This is first form:

  $ nc -l -p 6666 &
  $ curl  --request POST --data-binary "@README" http://localhost:6666

POST / HTTP/1.1
User-Agent: curl/7.21.0 (x86_64-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6

You probably request this:

-F/--form name=content
           (HTTP) This lets curl emulate a filled-in form in
              which a user has pressed the submit button. This
              causes curl to POST data using the Content- Type
              multipart/form-data according to RFC2388. This
              enables uploading of binary files etc. To force the
              'content' part to be a file, prefix the file name
              with an @ sign. To just get the content part from a
              file, prefix the file name with the symbol <. The
              difference between @ and < is then that @ makes a
              file get attached in the post as a file upload,
              while the < makes a text field and just get the
              contents for that text field from a file.

I've found version 0.7.1 Alpha of PuTTY Connection Manager to be the most stable (it was previously hidden on the forums). It's available from PuTTY Connection Manager – Website Down.

Easiest workaround is Just change the table name and all column names to lowercase and your issue will be resolved.

For example:

• Change Table_Name to table_name and
• Change ColumnName to columnname

I have tried xlrd, pandas, openpyxl and other such libraries and all of them seem to take exponential time as the file size increase as it reads the entire file. The other solutions mentioned above where they used 'on_demand' did not work for me. If you just want to get the sheet names initially, the following function works for xlsx files.

def get_sheet_details(file_path):
    sheets = []
    file_name = os.path.splitext(os.path.split(file_path)[-1])[0]
    # Make a temporary directory with the file name
    directory_to_extract_to = os.path.join(settings.MEDIA_ROOT, file_name)
    os.mkdir(directory_to_extract_to)

    # Extract the xlsx file as it is just a zip file
    zip_ref = zipfile.ZipFile(file_path, 'r')
    zip_ref.extractall(directory_to_extract_to)
    zip_ref.close()

    # Open the workbook.xml which is very light and only has meta data, get sheets from it
    path_to_workbook = os.path.join(directory_to_extract_to, 'xl', 'workbook.xml')
    with open(path_to_workbook, 'r') as f:
        xml = f.read()
        dictionary = xmltodict.parse(xml)
        for sheet in dictionary['workbook']['sheets']['sheet']:
            sheet_details = {
                'id': sheet['@sheetId'],
                'name': sheet['@name']
            }
            sheets.append(sheet_details)

    # Delete the extracted files directory
    shutil.rmtree(directory_to_extract_to)
    return sheets

Since all xlsx are basically zipped files, we extract the underlying xml data and read sheet names from the workbook directly which takes a fraction of a second as compared to the library functions.

Benchmarking: (On a 6mb xlsx file with 4 sheets)
Pandas, xlrd: 12 seconds
openpyxl: 24 seconds
Proposed method: 0.4 seconds

Since my requirement was just reading the sheet names, the unnecessary overhead of reading the entire time was bugging me so I took this route instead.

To load a .docx file:

    if let htmlFile = Bundle.main.path(forResource: "fileName", ofType: "docx") {
        let url = URL(fileURLWithPath: htmlFile)
        do{
            let data = try Data(contentsOf: url)
            self.webView.load(data, mimeType: "application/vnd.openxmlformats-officedocument.wordprocessingml.document", textEncodingName: "UTF-8", baseURL: url)
        }catch{
            print("errrr")
        }
    }

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Test {
    public static void main(String[] args) {
        Pattern pattern = Pattern.compile(".*'([^']*)'.*");
        String mydata = "some string with 'the data i want' inside";

        Matcher matcher = pattern.matcher(mydata);
        if(matcher.matches()) {
            System.out.println(matcher.group(1));
        }

    }
}

Actually, to me it happened in opposite way to another answers.

I did install the latest .NET Core SDK before the issue appeared (3.0.0-preview2 in my case) having not the latest version of Visual Studio (not sure if that would make any difference).

So, the solution was just to uninstall that latest .NET Core SDK. (This is not perfect if you need it, so you might consider Visual Studio upgrade to the latest one, but at least that solved ongoing issue).

If you can discount transient outages on the remote server you are trying to connect to, then that just leaves the local network config as a problem.

Using the IP address instead of the hostname is only going to work for the default domain on the remote host.

What happens when you try using www.google.com (or its IP address)? If you stil can't connect, then its something to do with the network between your server and the outside world.

I have seen JMS used in different commercial and academic projects. JMS can easily come into your picture, whenever you want to have a totally decoupled distributed systems. Generally speaking, when you need to send your request from one node, and someone in your network takes care of it without/with giving the sender any information about the receiver.

In my case, I have used JMS in developing a message-oriented middleware (MOM) in my thesis, where specific types of object-oriented objects are generated in one side as your request, and compiled and executed on the other side as your response.

There are some already defined data types which allows us to iterate over them easily e.g Array, Map, String Objects

Normal for in iterates over the iterator and in response provides us with the keys that are in the order of insertion as shown in below example.

  const numbers = [1,2,3,4,5];
   for(let number in number) {
     console.log(number);
   }

   // result: 0, 1, 2, 3, 4

Now if we try same with for of, then in response it provides us with the values not the keys. e.g

  const numbers = [1,2,3,4,5];
   for(let numbers of numbers) {
    console.log(number);
  }

  // result: 1, 2, 3, 4, 5

So looking at both of the iterators we can easily differentiate the difference between both of them.

Note:- For of only works with the Symbol.iterator

So if we try to iterate over normal object, then it will give us an error e.g-

const Room = {
   area: 1000,
   height: 7,
   floor: 2
 }

for(let prop in Room) {
 console.log(prop);
 } 

// Result area, height, floor

for(let prop of Room) {
  console.log(prop);
 } 

Room is not iterable

Now for iterating over we need to define an ES6 Symbol.iterator e.g

  const Room= {
    area: 1000, height: 7, floor: 2,
   [Symbol.iterator]: function* (){
    yield this.area;
    yield this.height;
    yield this.floors;
  }
}


for(let prop of Room) {
  console.log(prop);
 } 

//Result 1000, 7, 2

This is the difference between For in and For of. Hope that it might clear the difference.

Sometimes this happens because symlinks are not allowed in template settings: Advanced > Developer > Template Settings > Allow Symlinks

Use win APIs in your main function:

1. RegisterClassEx() note: you have to provide a pointer to a function (usually called WndProc) which handles windows messages such as WM_CREATE, WM_COMMAND etc
2. CreateWindowEx()
3. ShowWindow()
4. UpdateWindow()

Then write another function which handles win's messages (mentioned in #1). When you receive the message WM_CREATE you have to call CreateWindow(). The class is what control is that window, for example "edit" is a text box and "button" is a.. button :). You have to specify an ID for each control (of your choice but unique among all). CreateWindow() returns a handle to that control, which needs to be memorized. When the user clicks on a control you receive the WM_COMMAND message with the ID of that control. Here you can handle that event. You might find useful SetWindowText() and GetWindowText() which allows you to set/get the text of any control.
You will need only the win32 SDK. You can get it here.

DELETE t.* FROM test t WHERE t.name = 'foo' LIMIT 1

@Andre If I understood what you are asking, I think the only thing missing is the t.* before FROM.

Caller-saved registers (AKA volatile registers, or call-clobbered) are used to hold temporary quantities that need not be preserved across calls.

For that reason, it is the caller's responsibility to push these registers onto the stack or copy them somewhere else if it wants to restore this value after a procedure call.

It's normal to let a call destroy temporary values in these registers, though.

Callee-saved registers (AKA non-volatile registers, or call-preserved) are used to hold long-lived values that should be preserved across calls.

When the caller makes a procedure call, it can expect that those registers will hold the same value after the callee returns, making it the responsibility of the callee to save them and restore them before returning to the caller. Or to not touch them.

I have the same question but cannot ask it because it would be a duplicate.

The accepted answer, using exit, does not work when the script is a bit more complicated. If you use a background process to check for the condition, exit only exits that process, as it runs in a sub-shell. To kill the script, you have to explicitly kill it (at least that is the only way I know).

Here is a little script on how to do it:

#!/bin/bash

boom() {
    while true; do sleep 1.2; echo boom; done
}

f() {
    echo Hello
    N=0
    while
        ((N++ <10))
    do
        sleep 1
        echo $N
        #        ((N > 5)) && exit 4 # does not work
        ((N > 5)) && { kill -9 $$; exit 5; } # works 
    done
}

boom &
f &

while true; do sleep 0.5; echo beep; done

This is a better answer but still incomplete a I really don't know how to get rid of the boom part.

I was searching for a solution that worked with recordclass.RecordClass, supports nested objects and works for both json serialization and json deserialization.

Expanding on DS's answer, and expanding on solution from BeneStr, I came up with the following that seems to work:

Code:

import json
import recordclass

class NestedRec(recordclass.RecordClass):
    a : int = 0
    b : int = 0

class ExampleRec(recordclass.RecordClass):
    x : int       = None
    y : int       = None
    nested : NestedRec = NestedRec()

class JsonSerializer:
    @staticmethod
    def dumps(obj, ensure_ascii=True, indent=None, sort_keys=False):
        return json.dumps(obj, default=JsonSerializer.__obj_to_dict, ensure_ascii=ensure_ascii, indent=indent, sort_keys=sort_keys)

    @staticmethod
    def loads(s, klass):
        return JsonSerializer.__dict_to_obj(klass, json.loads(s))

    @staticmethod
    def __obj_to_dict(obj):
        if hasattr(obj, "_asdict"):
            return obj._asdict()
        else:
            return json.JSONEncoder().default(obj)

    @staticmethod
    def __dict_to_obj(klass, s_dict):
        kwargs = {
            key : JsonSerializer.__dict_to_obj(cls, s_dict[key]) if hasattr(cls,'_asdict') else s_dict[key] \
                for key,cls in klass.__annotations__.items() \
                    if s_dict is not None and key in s_dict
        }
        return klass(**kwargs)

Usage:

example_0 = ExampleRec(x = 10, y = 20, nested = NestedRec( a = 30, b = 40 ) )

#Serialize to JSON

json_str = JsonSerializer.dumps(example_0)
print(json_str)
#{
#  "x": 10,
#  "y": 20,
#  "nested": {
#    "a": 30,
#    "b": 40
#  }
#}

# Deserialize from JSON
example_1 = JsonSerializer.loads(json_str, ExampleRec)
example_1.x += 1
example_1.y += 1
example_1.nested.a += 1
example_1.nested.b += 1

json_str = JsonSerializer.dumps(example_1)
print(json_str)
#{
#  "x": 11,
#  "y": 21,
#  "nested": {
#    "a": 31,
#    "b": 41
#  }
#}

The table normally contains multiple rows. Use a loop and use row.Field<string>(0) to access the value of each row.

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>("File");
}

You can also access it via index:

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>(0);
}

If you expect only one row, you can also use the indexer of DataRowCollection:

string file = dt.Rows[0].Field<string>(0); 

Since this fails if the table is empty, use dt.Rows.Count to check if there is a row:

if(dt.Rows.Count > 0)
    file = dt.Rows[0].Field<string>(0);

Under Linux, in case you would like to call an external command that will execute independently (will keep running after the python script terminates), you can use a simple queue as task spooler or the at command

An example with task spooler:

import os
os.system('ts <your-command>')

Notes about task spooler (ts):

1. You could set the number of concurrent processes to be run ("slots") with:

   ts -S <number-of-slots>

2. Installing ts doesn't requires admin privileges. You can download and compile it from source with a simple make, add it to your path and you're done.

net stop <your service> && net start <your service>

No net restart, unfortunately.

You can explicitly have a join like this:

$qb->innerJoin('c.phones', 'p', Join::ON, 'c.id = p.customerId');

But you need to use the namespace of the class Join from doctrine:

use Doctrine\ORM\Query\Expr\Join;

Or if you prefere like that:

$qb->innerJoin('c.phones', 'p', Doctrine\ORM\Query\Expr\Join::ON, 'c.id = p.customerId');

Otherwise, Join class won't be detected and your script will crash...

Here the constructor of the innerJoin method:

public function innerJoin($join, $alias, $conditionType = null, $condition = null);

You can find other possibilities (not just join "ON", but also "WITH", etc...) here: http://docs.doctrine-project.org/en/2.0.x/reference/query-builder.html#the-expr-class

EDIT

Think it should be:

$qb->select('c')
    ->innerJoin('c.phones', 'p', Join::ON, 'c.id = p.customerId')
    ->where('c.username = :username')
    ->andWhere('p.phone = :phone');

    $qb->setParameters(array(
        'username' => $username,
        'phone' => $phone->getPhone(),
    ));

Otherwise I think you are performing a mix of ON and WITH, perhaps the problem.

I know this post is very old. I was actually looking for a solution to this myself. Some of the solutions posted work but they're pretty long so I decided to write my own version.

Directory.GetParent("./../..")

Basically what it does is:

1. . = will leave you in the same directory you are currently in.
2. / = in this context, the directory seperator.
3. .. = will move you one directory back (2x).
4. GetParent() = get the parent folder of ./../..

Combining all this together will leave you with: C:\Users\Oushima\Desktop\Homework\OoP\Assignment 1\part 1, (\part 1 being my project folder).

This is what worked for me. It's very similar to .Parent.Parent but shorter. I hope this will help someone else out.

If you want it to 100% return a string datatype then you can put .FullName behind it. Oh, and, don't forget the using System.IO; C# reference.

update: please check the answer of Jeff Gilliland below for updated solution

Seems like as this thread says a breaking change was issued:

Components can no longer be imported through "@angular/material". Use the individual secondary entry-points, such as @angular/material/button.

Update: can confirm, this was the issue. After downgrading @angular/[email protected]... to @angular/[email protected] we could solve this temporarily. Guess we need to update the project for a long term solution.

Update:

Short answer - You should almost always be using the utf8mb4 charset and utf8mb4_unicode_ci collation.

To alter database:

ALTER DATABASE dbname CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

See:

• Aaron's comment on this answer How to make MySQL handle UTF-8 properly

• What's the difference between utf8_general_ci and utf8_unicode_ci

• Conversion guide: https://dev.mysql.com/doc/refman/5.5/en/charset-unicode-conversion.html

Original Answer:

MySQL 4.1 and above has a default character set of UTF-8. You can verify this in your my.cnf file, remember to set both client and server (default-character-set and character-set-server).

If you have existing data that you wish to convert to UTF-8, dump your database, and import it back as UTF-8 making sure:

• use SET NAMES utf8 before you query/insert into the database
• use DEFAULT CHARSET=utf8 when creating new tables
• at this point your MySQL client and server should be in UTF-8 (see my.cnf). remember any languages you use (such as PHP) must be UTF-8 as well. Some versions of PHP will use their own MySQL client library, which may not be UTF-8 aware.

If you do want to migrate existing data remember to backup first! Lots of weird choping of data can happen when things don't go as planned!

Some resources:

• complete UTF-8 migration (cdbaby.com)
• article on UTF-8 readiness of php functions (note some of this information is outdated)

This is a classic self-join, try the following:

SELECT e.ename, e.empno, m.ename as manager, e.mgr
FROM
    emp e, emp m
WHERE e.mgr = m.empno

And if you want to include the president which has no manager then instead of an inner join use an outer join in Oracle syntax:

SELECT e.ename, e.empno, m.ename as manager, e.mgr
FROM
    emp e, emp m
WHERE e.mgr = m.empno(+)

Or in ANSI SQL syntax:

SELECT e.ename, e.empno, m.ename as manager, e.mgr
FROM
    emp e
    LEFT OUTER JOIN emp m
        ON e.mgr = m.empno

In case someone is trying to run a script in a RAILS environment, rails provide a runner to execute scripts in rails context via

rails runner my_script.rb

More details here: https://guides.rubyonrails.org/command_line.html#rails-runner

grep -F -r '0.49' * treats 0.49 as a "fixed" string instead of a regular expression. This makes . lose its special meaning.

Step 1 - check the current java version by "echo $JAVA_HOME"

Step 2 - vim /etc/profile

Step 3 - At the end of file you will find export JAVA_HOME, we need to provide the new path here, make sure that it is not relative.

Step 4 - Save and exit :wq

Step 5 - "source /etc/profile/", this would execute the change

Step 6 - Again do a echo $JAVA_HOME - change would have been reflected.

The steps described above do work, however I've encountered this problem on IntelliJ IDEA and have found that I'm having these problems with existing projects and the only solution is to remove the 'appcompat' module (not the library) and re-import it.

In order to create a cronjob, follow these steps:

1. run this command : SET GLOBAL event_scheduler = ON;

2. If ERROR 1229 (HY000): Variable 'event_scheduler' is a GLOBAL variable and should be set with SET GLOBAL: mportant

It is possible to set the Event Scheduler to DISABLED only at server startup. If event_scheduler is ON or OFF, you cannot set it to DISABLED at runtime. Also, if the Event Scheduler is set to DISABLED at startup, you cannot change the value of event_scheduler at runtime.

To disable the event scheduler, use one of the following two methods:

1. As a command-line option when starting the server:

   --event-scheduler=DISABLED
   

2. In the server configuration file (my.cnf, or my.ini on Windows systems): include the line where it will be read by the server (for example, in a [mysqld] section):

   event_scheduler=DISABLED
   

   Read MySQL documentation for more information.

    DROP EVENT IF EXISTS EVENT_NAME;
     CREATE EVENT EVENT_NAME
    ON SCHEDULE EVERY 10 SECOND/minute/hour
    DO
    CALL PROCEDURE_NAME();
   

robocopy:

Robocopy, or "Robust File Copy", is a command-line directory and/or file replication command. Robocopy functionally replaces Xcopy, with more options. It has been available as part of the Windows Resource Kit starting with Windows NT 4.0, and was first introduced as a standard feature in Windows Vista and Windows Server 2008. The command is robocopy...

As an update to Joe's answer, in that you can script the creation of the repository using the API, only the API call I needed was different. This may be because we are using bitbucket server, and not bitbucket cloud.

To create a new repo within a project on our server, I used:

curl -X POST -v -u USER:PASSWORD -H "Content-Type: application/json" \
http://SERVER/rest/api/1.0/projects/PROJECTNAME/repos/ \
-d '{"scmid":"git", "name":"REPONAME"}'

where USER, PASSWORD, SERVER, PROJECTNAME and REPONAME were of course the desired/required values.

The call is documented in the API reference.

/rest/api/1.0/projects/{projectKey}/repos

Create a new repository. Requires an existing project in which this repository will be created. The only parameters which will be used are name and scmId.

The authenticated user must have PROJECT_ADMIN permission for the context project to call this resource.

Here's an example (sorry for any typos)

var itemsToRemove = new ArrayList();  // should use generic List if you can

foreach (var item in originalArrayList) {
  if (...) {
    itemsToRemove.Add(item);
  }
}

foreach (var item in itemsToRemove) {
  originalArrayList.Remove(item);
}

OR if you're using 3.5, Linq makes the first bit easier:

itemsToRemove = originalArrayList
  .Where(item => ...)
  .ToArray();

foreach (var item in itemsToRemove) {
  originalArrayList.Remove(item);
}

Replace "..." with your condition that determines if item should be removed.

Add the below code in app.gradle this will solve all the library dependency errors

I've created this function to clean up a string that contained non numeric characters in a time field. The time contained question marks when they did not added the minutes, something like this 20:??. Function loops through each character and replaces the ? with a 0 :

 CREATE FUNCTION [dbo].[CleanTime]
(
    -- Add the parameters for the function here
    @intime nvarchar(10) 
)
RETURNS nvarchar(5)
AS
BEGIN
    -- Declare the return variable here
    DECLARE @ResultVar nvarchar(5)
    DECLARE @char char(1)
    -- Add the T-SQL statements to compute the return value here
    DECLARE @i int = 1
    WHILE @i <= LEN(@intime)
    BEGIN
    SELECT @char =  CASE WHEN substring(@intime,@i,1) like '%[0-9:]%' THEN substring(@intime,@i,1) ELSE '0' END
    SELECT @ResultVar = concat(@ResultVar,@char)   
    set @i  = @i + 1       
    END;
    -- Return the result of the function
    RETURN @ResultVar

END

Just remove the .val(). Like:

if ( $('html').attr('lang') == 'fr-FR' ) {
    // do this
} else {
    // do that
}

This is perhaps more succinct:

function toggle(element, klass) {
  var classes = element.className.match(/\S+/g) || [],
      index = classes.indexOf(klass);

  index >= 0 ? classes.splice(index, 1) : classes.push(klass);
  element.className = classes.join(' ');
}

Alternatively,

1) Without touching System.Reflection namespace,

GETNAME(new { myInput });

public static string GETNAME<T>(T myInput) where T : class
{
    if (myInput == null)
        return string.Empty;

    return myInput.ToString().TrimStart('{').TrimEnd('}').Split('=')[0].Trim();
}

2) The below one can be faster though (from my tests)

GETNAME(new { variable });
public static string GETNAME<T>(T myInput) where T : class
{
    if (myInput == null)
        return string.Empty;

    return typeof(T).GetProperties()[0].Name;
}

You can also extend this for properties of objects (may be with extension methods):

new { myClass.MyProperty1 }.GETNAME();

You can cache property values to improve performance further as property names don't change during runtime.

The Expression approach is going to be slower for my taste. To get parameter name and value together in one go see this answer of mine

Semicolon in the interpreter

Having read the answers, I still miss one important aspect of using semicolons, possibly the only one where it really makes a difference...

When you're working in an interpreter REPL (the Python interactive shell, IDLE, ipython) the value of the last expression is printed to the screen and usually this is the intended behavior.

Using an expression for side effects

But in some cases you want to evaluate an expression for its side effects only, e.g., to see the results of your simulation plotted by matplotlib.

In this cases you (probably) don't want to see the screenful of reprs of matplotlib objects that are sometimes returned by a call to a matplotlib function and, in IPython at least, one of the possibilities you have is to append a semicolon to the overly verbose statement, now IPython sees the input line as composed by two expressions, the matplotlib invocation and a null statement, so that the value of the compound expression is None and nothing is printed to the screen by the interpreter (the other possibility being assignment, as in _ = plot(...) but I find that a bit more intrusive).

Personal remark

IMHO, the use of the semicolon to suppress not desired output in the interpreter has become more relevant following the introduction of the IPyton notebook, that permits to save the input and the output, including graphical output, of an interpreter session for documentation and eventual reuse.

Simple Solution:

df['date_only'] = df['date_time_column'].dt.date

The tibble package now has a dedicated function that converts row names to an explicit variable.

library(tibble)
rownames_to_column(mtcars, var="das_Auto") %>% head

Gives:

           das_Auto  mpg cyl disp  hp drat    wt  qsec vs am gear carb

Those errors :

"CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage

CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage"

means you haven't installed mingw32-base.

Go to http://sourceforge.net/projects/mingw/files/latest/download?source=files

and then make sure you select "mingw32-base"

Make sure you set up environment variables correctly in PATH section. "C:\MinGW\bin"

After that open CMake and Select Installation --> Delete Cache.

And click configure button again. I solved the problem this way, hope you solve the problem.

You just need 775 for /var/www/html as long as you are logging in as myuser. The 7 octal in the middle (which is for "group" acl) ensures that the group has permission to read/write/execute. As long as you belong to the group that owns the files, "myuser" should be able to write to them. You may need to give group permissions to all the files in the docuemnt root, though:

chmod -R g+w /var/www/html

In general, to make sure something happens no matter what, you use

from exceptions import NameError

try:
    f = open(x)
except ErrorType as e:
    pass # handle the error
finally:
    try:
        f.close()
    except NameError: pass

finally blocks will be run whether or not there is an error in the try block, and whether or not there is an error in any error handling that takes place in except blocks. If you don't handle an exception that is raised, it will still be raised after the finally block is excecuted.

The general way to make sure a file is closed is to use a "context manager".

http://docs.python.org/reference/datamodel.html#context-managers

with open(x) as f:
    # do stuff

This will automatically close f.

For your question #2, bar gets closed on immediately when it's reference count reaches zero, so on del foo if there are no other references.

Objects are NOT created by __init__, they're created by __new__.

http://docs.python.org/reference/datamodel.html#object.new

When you do foo = Foo() two things are actually happening, first a new object is being created, __new__, then it is being initialized, __init__. So there is no way you could possibly call del foo before both those steps have taken place. However, if there is an error in __init__, __del__ will still be called because the object was actually already created in __new__.

Edit: Corrected when deletion happens if a reference count decreases to zero.

I modified Bootstrap SASS (v3.3.5) based on Rukshan's answer

Add this in the end of the calc-grid-column mixin in mixins/_grid-framework.scss, right below the $type == offset if condition.

@if ($type == offset-right) {
      .col-#{$class}-offset-right-#{$index} {
          margin-right: percentage(($index / $grid-columns));
      }
  }

Modify the make-grid mixin in mixins/_grid-framework.scss to generate the offset-right classes.

// Create grid for specific class
@mixin make-grid($class) {
  @include float-grid-columns($class);
  @include loop-grid-columns($grid-columns, $class, width);
  @include loop-grid-columns($grid-columns, $class, pull);
  @include loop-grid-columns($grid-columns, $class, push);
  @include loop-grid-columns($grid-columns, $class, offset);
  @include loop-grid-columns($grid-columns, $class, offset-right);
}

You can then use the classes like col-sm-offset-right-2 and col-md-offset-right-1

...and for your right click notification menu add a context menu to the form and edit it and set mouseclick events for each of contextmenuitems by double clicking them and then attach it to the notifyicon1 by selecting the ContextMenuStrip in notifyicon property.

Simply:

Integer i = 7;
Long l = new Long(i);

In my case the files were appeared as modified after changing the files permissions.

To make git ignore permission changes, do the following :

# For the current repository
git config core.filemode false   

# Globally
git config --global core.filemode false

Curl does that by default without any parameters or flags, I would use it for your purposes:

curl $url > /dev/null 2>&1

Curl is more about streams and wget is more about copying sites based on this comparison.

According to catalina.sh customizations should always go into your own setenv.sh (or setenv.bat respectively) eg:

CATALINA_OPTS='-Xms512m -Xmx1024m'

My guess is that setenv.bat will also be called when starting a service.I might be wrong, though, since I'm not a windows user.

Here is a working pandas subplot example, where modes is the column names of the dataframe.

    dpi=200
    figure_size=(20, 10)
    fig, ax = plt.subplots(len(modes), 1, sharex="all", sharey="all", dpi=dpi)
    for i in range(len(modes)):
        ax[i] = pivot_df.loc[:, modes[i]].plot.bar(figsize=(figure_size[0], figure_size[1]*len(modes)),
                                                   ax=ax[i], title=modes[i], color=my_colors[i])
        ax[i].legend()
    fig.suptitle(name)

If you're using Qt Jambi, this should work:

QApplication.closeAllWindows();

Though this is an old post, I am posting how I resolved in case it helps others. Since I used sudo to do the install of the boto3 library the permissions on the boto3 directory was set to 700. Either change the permissions to be readable by others or run the python command as sudo.

for email and password validation try

  if (isValidEmail(et_regemail.getText().toString())&&etpass1.getText().toString().length()>7){
      if (validatePassword(etpass1.getText().toString())) {
      Toast.makeText(getApplicationContext(),"Go Ahead".....
      }
      else{

       Toast.makeText(getApplicationContext(),"InvalidPassword".....
       }

}else{

 Toast.makeText(getApplicationContext(),"Invalid Email".....
}


public boolean validatePassword(final String password){
    Pattern pattern;
    Matcher matcher;
    final String PASSWORD_PATTERN = "^(?=.*[0-9])(?=.*[A-Z])(?=.* 
    [@#$%^&+=!])(?=\\S+$).{4,}$";
    pattern = Pattern.compile(PASSWORD_PATTERN);
    matcher = pattern.matcher(password);

    return matcher.matches();
}

public final static boolean isValidEmail(CharSequence target) {
    if (target == null)
        return false;

    return android.util.Patterns.EMAIL_ADDRESS.matcher(target).matches();
}

You are trying to assign to literal integer values. 1, 2, etc. are not valid names; they are only valid integers:

>>> 1
1
>>> 1 = 'something'
  File "<stdin>", line 1
SyntaxError: can't assign to literal

You probably want to use a list or dictionary instead:

names = []
for i in range(1, 6):
    name = input("Please enter name {}:".format(i))
    names.append(name)

Using a list makes it much easier to pick a random value too:

winner = random.choice(names)
print('Well done {}. You are the winner!'.format(winner))

Hard to find a clear answer from the Oracle site. The following is from javax.ws.rs.core.HttpHeaders.java:

/**
 * See {@link <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.1">HTTP/1.1 documentation</a>}.
 */
public static final String ACCEPT = "Accept";

/**
 * See {@link <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.2">HTTP/1.1 documentation</a>}.
 */
public static final String ACCEPT_CHARSET = "Accept-Charset";

Not with CSS directly, you could set CSS properties via JavaScript based on the internal contents but in the end you would still need to be operating in the definitions of CSS.

    int x=550;
    string s=" ";
    string y=" ";

    while (x>0)
    {

        s += x%2;
        x=x/2;
    }


    Console.WriteLine(Reverse(s));
}

public static string Reverse( string s )
{
    char[] charArray = s.ToCharArray();
    Array.Reverse( charArray );
    return new string( charArray );
}

• Removing the Run Configuration

  Sometimes I have a similar problems in some pre-release versions of eclipse. For fix the error, I delete the Run Configuration. You can find that in menu Run, Run Configurations...

  Then I launch the app with Alt+Shift+X, then J. If this don't work, Ctrl+F11.

• Deleting the .metadata directory

  In another way, the configuration settings for your current workspace may are corrupted. Those settings are in the .metadata directory in your current workspace ¹. In that case, there is no other choice than delete the directory:

  1. Close eclipse.
  2. Delete the .metadata directory.
  3. Start eclipse.
  4. Import the projects.
  5. Run the project again.

Notes

1. You will see that directory with File > Switch Workspace > Other...

This code will print a pyramid of dollars.

public static void main(String[] args) {

     for(int i=0;i<5;i++) {
         for(int j=0;j<5-i;j++) {
             System.out.print(" ");
         }
        for(int k=0;k<=i;k++) {
            System.out.print("$ ");
        }
        System.out.println();  
    }

}

OUPUT :

     $ 
    $ $ 
   $ $ $ 
  $ $ $ $ 
 $ $ $ $ $

You can add the script tags like how we use in the asp.net while doing client side validations like below.

@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>
<script type="text/javascript" src="~/Scripts/jquery-3.1.1.min.js"></script>
<script type="text/javascript">
    $(function () {
       //Your code
    });
</script>

This worked great for me

$this->db->where('sell_date BETWEEN "'. date('Y-m-d', strtotime($start_date)). '" and "'. date('Y-m-d', strtotime($end_date)).'"');

Looks like your file.next() line in the while loop is throwing the NoSuchElementException since the scanner reached the end of file. Read the next() java API here

Also you should not call next() in the loop and also in the while condition. In the while condition you should check if next token is available and inside the while loop check if its equal to treasure.

You can try this:

<?php
    echo (($var=='abc' || $var=='def' || $var=='hij' || $var=='klm' || $var=='nop') ? "true" : "false");
?>

Because on the second loop, $v is still a reference to the last array item, so it's overwritten each time.

You can see it like that:

$a = array ('zero','one','two', 'three');

foreach ($a as &$v) {

}

foreach ($a as $v) {
  echo $v.'-'.$a[3].PHP_EOL;
}

As you can see, the last array item takes the current loop value: 'zero', 'one', 'two', and then it's just 'two'... : )

It looks like you are using a custom Kubernetes Cluster (using minikube, kubeadm or the like). In this case, there is no LoadBalancer integrated (unlike AWS or Google Cloud). With this default setup, you can only use NodePort or an Ingress Controller.

With the Ingress Controller you can setup a domain name which maps to your pod; you don't need to give your Service the LoadBalancer type if you use an Ingress Controller.

I managed this without adding markup, but instead using li:before. This obviously has all the limitations of :before (no old IE support), but it seems to work with IE8, Firefox and Chrome after some very limited testing. The bullet style is also limited by what's in unicode.

li {_x000D_
  list-style: none;_x000D_
}_x000D_
li:before {_x000D_
  /* For a round bullet */_x000D_
  content: '\2022';_x000D_
  /* For a square bullet */_x000D_
  /*content:'\25A0';*/_x000D_
  display: block;_x000D_
  position: relative;_x000D_
  max-width: 0;_x000D_
  max-height: 0;_x000D_
  left: -10px;_x000D_
  top: 0;_x000D_
  color: green;_x000D_
  font-size: 20px;_x000D_
}

<ul>_x000D_
  <li>foo</li>_x000D_
  <li>bar</li>_x000D_
</ul>

You can calculate the checksum of a file by reading the binary data and using hashlib.md5().hexdigest(). A function to do this would look like the following:

def File_Checksum_Dis(dirname):
    
    if not os.path.exists(dirname):
        print(dirname+" directory is not existing");
    
    for fname in os.listdir(dirname):
        if not fname.endswith('~'):
            fnaav = os.path.join(dirname, fname);
            fd = open(fnaav, 'rb');
            data = fd.read();
            fd.close();
        
            print("-"*70);
            print("File Name is: ",fname);          
            print(hashlib.md5(data).hexdigest())
            print("-"*70);
                

You can use find with Perl. Command will be like this:

find file | perl -lne '$t = "/path/to/copy/file/to/is/very/deep/there/"; /^(.+)\/.+$/; `mkdir -p $t$1` unless(-d "$t$1"); `cp $_ $t$_` unless(-f "$t$_");'

This command will create directory $t if it doesn't exist. And than copy file into $t only unless file exists inside $t.

Try something like this one!

Instead of getting the context like:(this works for getting array index's)

$result['context']

try (this work for getting objects)

$result->context

Other Example is: (if $result has multiple data values)

Array
(
    [0] => stdClass Object
        (
            [id] => 15
            [name] => 1 Pc Meal
            [context] => 5
            [restaurant_id] => 2
            [items] => 
            [details] => 1 Thigh (or 2 Drums) along with Taters
            [nutrition_fact] => {"":""}
            [servings] => menu
            [availability] => 1
            [has_discount] => {"menu":0}
            [price] => {"menu":"8.03"}
            [discounted_price] => {"menu":""}
            [thumbnail] => YPenWSkFZm2BrJT4637o.jpg
            [slug] => 1-pc-meal
            [created_at] => 1612290600
            [updated_at] => 1612463400
        )

)

Then try this:

foreach($result as $results)
{
      $results->context;
}

You can use the semver package to determine if a version satisfies a semantic version requirement. This is not the same as comparing two actual versions, but is a type of comparison.

For example, version 3.6.0+1234 should be the same as 3.6.0.

import semver
semver.match('3.6.0+1234', '==3.6.0')
# True

from packaging import version
version.parse('3.6.0+1234') == version.parse('3.6.0')
# False

from distutils.version import LooseVersion
LooseVersion('3.6.0+1234') == LooseVersion('3.6.0')
# False

I was successful in doing this using file://, but with one additional slash to denote an absolute path.

git clone file:///cygdrive/c/path/to/repository/

In my case I'm using Git on Cygwin for Windows, which you can see because of the /cygdrive/c part in my paths. With some tweaking to the path it should work with any git installation.

Adding a remote works the same way

git remote add remotename file:///cygdrive/c/path/to/repository/

You could use sparse(a), which would return

(1,2) 1

(1,4) 3

This allows you to keep the information about where your non-zero entries used to be.

As Brian points out the GC can collect anything that is unreachable including objects that are still in scope and even while instance methods of those objects are still executing. consider the following code:

class foo
{
    static int liveFooInstances;

    public foo()
    {
        Interlocked.Increment(ref foo.liveFooInstances);
    }

    public void TestMethod()
    {
        Console.WriteLine("entering method");
        while (Interlocked.CompareExchange(ref foo.liveFooInstances, 1, 1) == 1)
        {
            Console.WriteLine("running GC.Collect");
            GC.Collect();
            GC.WaitForPendingFinalizers();
        }
        Console.WriteLine("exiting method");
    }

    ~foo()
    {
        Console.WriteLine("in ~foo");
        Interlocked.Decrement(ref foo.liveFooInstances);
    }

}

class Program
{

    static void Main(string[] args)
    {
        foo aFoo = new foo();
        aFoo.TestMethod();
        //Console.WriteLine(aFoo.ToString()); // if this line is uncommented TestMethod will never return
    }
}

if run with a debug build, with the debugger attached, or with the specified line uncommented TestMethod will never return. But running without a debugger attached TestMethod will return.

Just use:

overflow: hidden;
white-space: nowrap;

In your item's divs

Simple example: Form with textbox and Search button.

If you write "name" into the textbox and submit form, it will brings you patients with "name" in table.

View:

@using (Ajax.BeginForm("GetPatients", "Patient", new AjaxOptions {//GetPatients is name of method in PatientController
    InsertionMode = InsertionMode.Replace, //target element(#patientList) will be replaced
    UpdateTargetId = "patientList",
    LoadingElementId = "loader" // div with .gif loader - that is shown when data are loading   
}))
{
    string patient_Name = "";
    @Html.EditorFor(x=>patient_Name) //text box with name and id, that it will pass to controller
    <input  type="submit" value="Search" />
}

@* ... *@
<div id="loader" class=" aletr" style="display:none">
    Loading...<img src="~/Images/ajax-loader.gif" />
</div>
@Html.Partial("_patientList") @* this is view with patient table. Same view you will return from controller *@

_patientList.cshtml:

@model IEnumerable<YourApp.Models.Patient>

<table id="patientList" >
<tr>
    <th>
        @Html.DisplayNameFor(model => model.Name)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.Number)
    </th>       
</tr>
@foreach (var patient in Model) {
<tr>
    <td>
        @Html.DisplayFor(modelItem => patient.Name)
    </td>
    <td>
        @Html.DisplayFor(modelItem => patient.Number)
    </td>
</tr>
}
</table>

Patient.cs

public class Patient
{
   public string Name { get; set; }
   public int Number{ get; set; }
}

PatientController.cs

public PartialViewResult GetPatients(string patient_Name="")
{
   var patients = yourDBcontext.Patients.Where(x=>x.Name.Contains(patient_Name))
   return PartialView("_patientList", patients);
}

And also as TSmith said in comments, don´t forget to install jQuery Unobtrusive Ajax library through NuGet.

route -f causes damage. So we need to either disconnect the correct parts of the routing table or find out how to rebuild it.

You can also try dism /online /Enable-Feature /FeatureName:TelnetClient

Run this command with "Run as an administrator"

Reference

Add following rule to tr and it should work

float: left

Sample (Open it in IE9 offcourse :) ): http://jsfiddle.net/zshmN/

EDIT: This isn't a legal or correct solution as pointed out by many, but if you are left with no option and need something this will work in IE9.

So all those who are giving down votes, please let us know correct solution as well

You can try something like this

IFNULL(NULLIF(X, '' ), 0)

Attribute X is assumed to be empty if it is an empty String, so after that you can declare as a zero instead of last value. In another case, it would remain its original value.

Anyway, just to give another way to do that.

infile = open('filename.txt', 'r')
firstLine = infile.readline()

Angus Croll recently wrote an interesting blog post about this -

http://javascriptweblog.wordpress.com/2011/08/08/fixing-the-javascript-typeof-operator/

He goes through the pros and cons of the various methods then defines a new method 'toType' -

var toType = function(obj) {
  return ({}).toString.call(obj).match(/\s([a-zA-Z]+)/)[1].toLowerCase()
}

Here is a work-around:

1. Create a js directory in the same directory as your index.html
2. Download popper.min.js from the following site into said js directory https://github.com/FezVrasta/popper.js#installation

e.g.: https://unpkg.com/popper.js/dist/umd/popper.min.js

2. Change your the src of your script include to look like this:

   src="js/popper.min.js"

Note that you've removed Popper from npm version control, so you'll have to manually download updates.

That's the easiest way to delete all rows from the table in dbms via DataAdapter. But if you want to do it in one batch, you can set the DataAdapter's UpdateBatchSize to 0(unlimited).

Another way would be to use a simple SqlCommand with CommandText DELETE FROM Table:

using(var con = new SqlConnection(ConfigurationSettings.AppSettings["con"]))
using(var cmd = new SqlCommand())
{
    cmd.CommandText = "DELETE FROM Table";
    cmd.Connection = con;
    con.Open();
    int numberDeleted = cmd.ExecuteNonQuery();  // all rows deleted
}

But if you instead only want to remove the DataRows from the DataTable, you just have to call DataTable.Clear. That would prevent any rows from being deleted in dbms.

It would be great if you use :hover pseudo class over the onmouseover event

td:hover
{
   background-color:white
}

and for the default styling just use

td
{
  background-color:black
}

As you want to use these styling not over all the td elements then you need to specify the class to those elements and add styling to that class like this

.customTD
{
   background-color:black
}
.customTD:hover
{
  background-color:white;
}

You can also use :nth-child selector to select the td elements

I faced the similar issue on new server that I built through automated scripts via vcenter api. Looks like the "Remote Procedure Call (RPC)" service may not be running on the remote machine. you need to wait for the service to come up to use the Get-WmiObject command. Hence I simply put the script into sleep for sometime and it worked.

like other said, clear and fill worked for me:

    var elem = $('#input_field');

Your browser first resolves the servername via DNS to an IP. Then it opens a TCP connection to the webserver and tries to communicate via HTTP. Usually that is on TCP-port 80 but you can specify a different one (http://server:portnumber).

HTTP looks like this:

Once it is connected, it sends the request, which looks like:

GET /site HTTP/1.0
Header1: bla
Header2: blub
{emptyline}

E.g., a header might be Authorization or Range. See here for more.

Then the server responds like this:

200 OK
Header3: foo
Header4: bar

content following here...

E.g., a header might be Date or Content-Type. See here for more.

Look at Wikipedia for HTTP for some more information about this protocol.

Synchronized Method

Pros:

• Your IDE can indicate the synchronized methods.
• The syntax is more compact.
• Forces to split the synchronized blocks to separate methods.

Cons:

• Synchronizes to this and so makes it possible to outsiders to synchronize to it too.
• It is harder to move code outside the synchronized block.

Synchronized block

Pros:

• Allows using a private variable for the lock and so forcing the lock to stay inside the class.
• Synchronized blocks can be found by searching references to the variable.

Cons:

• The syntax is more complicated and so makes the code harder to read.

Personally I prefer using synchronized methods with classes focused only to the thing needing synchronization. Such class should be as small as possible and so it should be easy to review the synchronization. Others shouldn't need to care about synchronization.

Use substr($path, strrpos($path,'.')+1);. It is the fastest method of all compares.

@Kurt Zhong already answered.

Let's check the comparative result here: https://eval.in/661574

• Changing Values:
  • array_map cannot change the values inside input array(s) while array_walk can; in particular, array_map never changes its arguments.
• Array Keys Access:
  • array_map cannot operate with the array keys, array_walk can.
• Return Value:
  • array_map returns a new array, array_walk only returns true. Hence, if you don't want to create an array as a result of traversing one array, you should use array_walk.
• Iterating Multiple Arrays:
  • array_map also can receive an arbitrary number of arrays and it can iterate over them in parallel, while array_walk operates only on one.
• Passing Arbitrary Data to Callback:
  • array_walk can receive an extra arbitrary parameter to pass to the callback. This mostly irrelevant since PHP 5.3 (when anonymous functions were introduced).
• Length of Returned Array:
  • The resulting array of array_map has the same length as that of the largest input array; array_walk does not return an array but at the same time it cannot alter the number of elements of original array; array_filter picks only a subset of the elements of the array according to a filtering function. It does preserve the keys.

Example:

<pre>
<?php

$origarray1 = array(2.4, 2.6, 3.5);
$origarray2 = array(2.4, 2.6, 3.5);

print_r(array_map('floor', $origarray1)); // $origarray1 stays the same

// changes $origarray2
array_walk($origarray2, function (&$v, $k) { $v = floor($v); }); 
print_r($origarray2);

// this is a more proper use of array_walk
array_walk($origarray1, function ($v, $k) { echo "$k => $v", "\n"; });

// array_map accepts several arrays
print_r(
    array_map(function ($a, $b) { return $a * $b; }, $origarray1, $origarray2)
);

// select only elements that are > 2.5
print_r(
    array_filter($origarray1, function ($a) { return $a > 2.5; })
);

?>
</pre>

Result:

Array
(
    [0] => 2
    [1] => 2
    [2] => 3
)
Array
(
    [0] => 2
    [1] => 2
    [2] => 3
)
0 => 2.4
1 => 2.6
2 => 3.5
Array
(
    [0] => 4.8
    [1] => 5.2
    [2] => 10.5
)
Array
(
    [1] => 2.6
    [2] => 3.5
)

You can use sort.Slice() plus sort.Search()

type Person struct {
    Name string
}

func main() {
    crowd := []Person{{"Zoey"}, {"Anna"}, {"Benni"}, {"Chris"}}

    sort.Slice(crowd, func(i, j int) bool {
        return crowd[i].Name <= crowd[j].Name
    })

    needle := "Benni"
    idx := sort.Search(len(crowd), func(i int) bool {
        return string(crowd[i].Name) >= needle
    })

    if crowd[idx].Name == needle {
        fmt.Println("Found:", idx, crowd[idx])
    } else {
        fmt.Println("Found noting: ", idx)
    }
}

The accepted answer fails when trying to repeat deleting words, try this solution instead:

" delete current word, insert and normal modes
inoremap <C-BS> <C-O>b<C-O>dw
noremap <C-BS> bdw

It maps CTRL-BackSpace, also working in normal mode.

You need to write() the read() data into the new file:

ssize_t nrd;
int fd;
int fd1;

fd = open(aa[1], O_RDONLY);
fd1 = open(aa[2], O_CREAT | O_WRONLY, S_IRUSR | S_IWUSR);
while (nrd = read(fd,buffer,50)) {
    write(fd1,buffer,nrd);
}

close(fd);
close(fd1);

Update: added the proper opens...

Btw, the O_CREAT can be OR'd (O_CREAT | O_WRONLY). You are actually opening too many file handles. Just do the open once.

I am a bit late in to the game, but here is one solution which works fine:

    void Main()
    {
        var dateResult = GetRandomDates(new DateTime(1995, 1, 1), DateTime.UtcNow, 100);
        foreach (var r in dateResult)
            Console.WriteLine(r);
    }

    public static IList<DateTime> GetRandomDates(DateTime startDate, DateTime maxDate, int range)
    {
        var randomResult = GetRandomNumbers(range).ToArray();

        var calculationValue = maxDate.Subtract(startDate).TotalMinutes / int.MaxValue;
        var dateResults = randomResult.Select(s => startDate.AddMinutes(s * calculationValue)).ToList();
        return dateResults;
    }

    public static IEnumerable<int> GetRandomNumbers(int size)
    {
        var data = new byte[4];
        using (var rng = new System.Security.Cryptography.RNGCryptoServiceProvider(data))
        {
            for (int i = 0; i < size; i++)
            {
                rng.GetBytes(data);

                var value = BitConverter.ToInt32(data, 0);
                yield return value < 0 ? value * -1 : value;
            }
        }
    }

JavaScript is fired on client side and JSP is on server-side. So I can say that it is impossible.

Depending on your application, you'll probably want to use that Font assignment either on text change or focus/unfocus of the textbox in question.

Here's a quick sample of what it could look like (empty form, with just a textbox. Font turns bold when the text reads 'bold', case-insensitive):

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        RegisterEvents();
    }

    private void RegisterEvents()
    {
        _tboTest.TextChanged += new EventHandler(TboTest_TextChanged);
    }

    private void TboTest_TextChanged(object sender, EventArgs e)
    {
        // Change the text to bold on specified condition
        if (_tboTest.Text.Equals("Bold", StringComparison.OrdinalIgnoreCase))
        {
            _tboTest.Font = new Font(_tboTest.Font, FontStyle.Bold);
        }
        else
        {
            _tboTest.Font = new Font(_tboTest.Font, FontStyle.Regular);
        }
    }
}

DECLARE @iMonth INT=12

Here is directive from the official examples angular docs v1.5 that shows how to compile html:

.directive('compileHtml', function ($compile) {
  return function (scope, element, attrs) {
    scope.$watch(
      function(scope) {
        return scope.$eval(attrs.compileHtml);
      },
      function(value) {
        element.html(value);
        $compile(element.contents())(scope);
      }
    );
  };
});

Usage:

<div compile-html="item.htmlString"></div>

It will insert item.htmlString property as html any place, like

<li ng-repeat="item in itemList">
    <div compile-html="item.htmlString"></div>

Take a look at http://start.spring.io/ it basically gives you a kick starter with either maven or gradle build.

Just for fun I took Siddharth's suggestion of separate textboxes and did comboboxes. If anybody's interested, add a userform with three comboboxes named cboDay, cboMonth and cboYear and arrange them left to right. Then paste the code below into the UserForm's code module. The required combobox properties are set in UserFormInitialization, so no additional prep should be required.

The tricky part is changing the day when it becomes invalid because of a change in year or month. This code just resets it to 01 when that happens and highlights cboDay.

I haven't coded anything like this in a while. Hopefully it will be of interest to somebody, someday. If not it was fun!

This may be a sideways answer, but if you download Virtuemart (A Joomla component), it has a countries table and all the related states all set up for you included in the installation SQL. They're called jos_virtuemart_countries and jos_virtuemart_states. It also includes the 2 and 3 character country codes. I'd attach it to my answer, but don't see a way of doing it.

You don't need to add '.' in your class name. This will do

document.getElementsByClassName('col1')

Additionally, since you haven't define the background color via javascript, you won't able to call it directly. You have to use window.getComputedStyle() or jquery to achieve what you are trying to do above.

Here is a working example

http://jsfiddle.net/J9LU8/

macOS default termianl

macOS 10.15.7

1. open Terminal
2. click Prefrences...
3. select Window tab
4. just change Scrollback to Limit number of rows to: what your wanted.

my screenshots

 $table  = 'your table name';
 $column = 'q6'
 $add = mysql_query("ALTER TABLE $table ADD $column VARCHAR( 255 ) NOT NULL");

you can change VARCHAR( 255 ) NOT NULL into what ever datatype you want.

Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.

You've got:

//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]

Which translates into:

Get me all the elements that have an ID that contains ctl00_btnAircraftMapCell. Out of these elements, get any child elements that have a title that contains Select Seat.

What you actually want is:

//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]

Which translates into:

Get me all the anchor elements that have both: an id that contains ctl00_btnAircraftMapCell and a title that contains Select Seat.

You can also do this with linq if you'd like

var names = new List<string>() { "John", "Anna", "Monica" };
var joinedNames = names.Aggregate((a, b) => a + ", " + b);

Although I prefer the non-linq syntax in Quartermeister's answer and I think Aggregate might perform slower (probably more string concatenation operations).

I have tried both the options suggested by Michael Munsey and works for me.

I wanted to provide another option to view the filtered tables. Mouse Right Click your table trees node and Select "Apply Filter" and check "Include Synonyms" check box and click Okay. That's it, you should be able to view the tables right there. It works for me.

Using query comprehension syntax you could achieve the orderby as follows:

var uniqueColors = (from dbo in database.MainTable
                    where dbo.Property
                    orderby dbo.Color.Name ascending
                    select dbo.Color.Name).Distinct();

You can find the default Android menu icons here - link is broken now.

Update: You can find Material Design icons here.

textView2.setText(String.format("%.2f", result));

and

DecimalFormat form = new DecimalFormat("0.00");
         textView2.setText(form.format(result) );

...cause "NumberFormatException" error in locale for Europe because it sets result as comma instead of point decimal - error occurs when textView is added to number in editText. Both solutions are working excellent in locale US and UK.

An alternative solution is to introduce a method to the file instance that would do the explicit conversion.

import types

def _write_str(self, ascii_str):
    self.write(ascii_str.encode('ascii'))

source_file = open("myfile.bin", "wb")
source_file.write_str = types.MethodType(_write_str, source_file)

And then you can use it as source_file.write_str("Hello World").

I encountered a similar problem, with a syntax error that I knew should not be a syntax error. In my case it turned out that a Python 2 interpreter was trying to run Python 3 code, or vice versa; I think that my shell had a PYTHONPATH with a mixture of Python 2 and Python 3.

Online index rebuilds are less intrusive when it comes to locking tables. Offline rebuilds cause heavy locking of tables which can cause significant blocking issues for things that are trying to access the database while the rebuild takes place.

"Table locks are applied for the duration of the index operation [during an offline rebuild]. An offline index operation that creates, rebuilds, or drops a clustered, spatial, or XML index, or rebuilds or drops a nonclustered index, acquires a Schema modification (Sch-M) lock on the table. This prevents all user access to the underlying table for the duration of the operation. An offline index operation that creates a nonclustered index acquires a Shared (S) lock on the table. This prevents updates to the underlying table but allows read operations, such as SELECT statements."

http://msdn.microsoft.com/en-us/library/ms188388(v=sql.110).aspx

Additionally online index rebuilds are a enterprise (or developer) version only feature.

Here's the mysql reference for cursors. So I'm guessing it's something like this:

  DECLARE done INT DEFAULT 0;
  DECLARE products_id INT;
  DECLARE result varchar(4000);
  DECLARE cur1 CURSOR FOR SELECT products_id FROM sets_products WHERE set_id = 1;
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;

  OPEN cur1;

  REPEAT
    FETCH cur1 INTO products_id;
    IF NOT done THEN
      CALL generate_parameter_list(@product_id, @result);
      SET param = param + "," + result; -- not sure on this syntax
    END IF;
  UNTIL done END REPEAT;

  CLOSE cur1;

  -- now trim off the trailing , if desired

-- Procedure output can be collected from variables x and y (ans1:= x and ans2:=y) will be: 150 and 20 respectively.

-- Answer borrowed from: https://stackoverflow.com/a/9484228/1661078

you can 'invoke' alternative bindings on Y this way:

...registered(X, Y), (Y=ct101; Y=ct102; Y=ct103).

Note the parenthesis are required to keep the correct execution control flow. The ;/2 it's the general or operator. For your restricted use you could as well choice the more idiomatic

...registered(X, Y), member(Y, [ct101,ct102,ct103]).

that on backtracking binds Y to each member of the list.

edit I understood with a delay your last requirement. If you want that Y match all 3 values the or is inappropriate, use instead

...registered(X, ct101), registered(X, ct102), registered(X, ct103).

or the more compact

...findall(Y, registered(X, Y), L), sort(L, [ct101,ct102,ct103]).

findall/3 build the list in the very same order that registered/2 succeeds. Then I use sort to ensure the matching.

...setof(Y, registered(X, Y), [ct101,ct102,ct103]).

setof/3 also sorts the result list

Identifiers (including column names) that are not double-quoted are folded to lower case in PostgreSQL. Column names that were created with double-quotes and thereby retained upper-case letters (and/or other syntax violations) have to be double-quoted for the rest of their life:

"first_Name"

Values (string literals / constants) are enclosed in single quotes:

'xyz'

So, yes, PostgreSQL column names are case-sensitive (when double-quoted):

SELECT * FROM persons WHERE "first_Name" = 'xyz';

Read the manual on identifiers here.

My standing advice is to use legal, lower-case names exclusively so double-quoting is not needed.

Thanks for the responses. I think I've solved the problem just now.

Since LD_PRELOAD is for setting some library proloaded, I check the library that ld preloads with LD_PRELOAD, one of which is "liblunar-calendar-preload.so", that is not existing in the path "/usr/lib/liblunar-calendar-preload.so", but I find a similar library "liblunar-calendar-preload-2.0.so", which is a difference version of the former one.

Then I guess maybe liblunar-calendar-preload.so was updated to a 2.0 version when the system updated, leaving LD_PRELOAD remain to be "/usr/lib/liblunar-calendar-preload.so". Thus the preload library name was not updated to the newest version.

To avoid changing environment variable, I create a symbolic link under the path "/usr/lib"

sudo ln -s liblunar-calendar-preload-2.0.so liblunar-calendar-preload.so

Then I restart bash, the error is gone.

Reuses cells while scrolling up/down - this is possible with implementing View Holder in the listView adapter, but it was an optional thing, while in the RecycleView it's the default way of writing adapter.

Decouples list from its container - so you can put list items easily at run time in the different containers (linearLayout, gridLayout) with setting LayoutManager.

Example:

mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
//or
mRecyclerView.setLayoutManager(new GridLayoutManager(this, 2));
mRecyclerView.setLayoutManager(new GridLayoutManager(this, 3));

• Animates common list actions.

• Animations are decoupled and delegated to ItemAnimator.

There is more about RecyclerView, but I think these points are the main ones.

LayoutManager

i) LinearLayoutManager - which supports both vertical and horizontal lists,

ii) StaggeredLayoutManager - which supports Pinterest like staggered lists,

iii) GridLayoutManager - which supports displaying grids as seen in Gallery apps.

And the best thing is that we can do all these dynamically as we want.

Add include_directories("/your/path/here").

This will be similar to calling gcc with -I/your/path/here/ option.

Make sure you put double quotes around the path. Other people didn't mention that and it made me stuck for 2 days. So this answer is for people who are very new to CMake and very confused.

Simply add an attribute to your popover! See my JSFiddle if you're in a hurry.

We want to add an ID or a class to a particular popover so that we may customize it the way we want via CSS.

Please note that we don't want to customize all popovers! This is terrible idea.

Here is a simple example - display the popover like this:

// We add the id 'my-popover'_x000D_
$("#my-button").popover({_x000D_
    html : true,_x000D_
    placement: 'bottom'_x000D_
}).data('bs.popover').tip().attr('id', 'my-popover');

#my-popover {_x000D_
    left: -169px!important;_x000D_
}_x000D_
#my-popover .arrow {_x000D_
    left: 90%_x000D_

Don't have enough cred to comment on the top voted answer, but at least in my rails environment (running 4), rails s is at http://localhost:3000, not http://www.localhost:3000. When I changed it to http://localhost:3000, it worked just fine. No need to edit any hosts file.

2. New and improved solution coming in Bootstrap 3.0 - they're adding a separate print.less file. See separate print.less

i supposed you uploaded your photo in your drive all what you need to do is while you are opening your google drive just open your dev tools in chrome and head to your img tag and copy the link beside the src attribute and use it

$mail->IsSMTP();
$mail->Host = "smtp.gmail.com";
$mail->SMTPAuth = true;
$mail->SMTPSecure = "ssl";
$mail->Username = "[email protected]";
$mail->Password = "**********";
$mail->Port = "465";

That is a working configuration.

try to replace what you have

Can't you just make a copy constructor? By the way Java always passes references by value, so you keep pointing to the same object.

Try this

void Function()
{
    while (condition) 
    {
        await Task.Delay(1);
    }
}

This will make the program wait until the condition is not true. You can just invert it by adding a "!" infront of the condition so that it will wait until the condition is true.

if the .bash_profile does not exist you can try run the following command:

. ~/.bashrc 

or

 source ~/.bashrc

instead of .bash_profile. You can find more information about bashrc

You can use below instead:

DateTime.Now.Ticks

First make sure that you have a SSH key or generate one at: https://help.github.com/articles/generating-ssh-keys/

Once you have your key, you have to add it to your github account at: https://github.com/settings/ssh

For Windows users it's useful to run git bash as an administrator.

Now the cloning should work for private repositories (repo), without having to put your username and password.

The image you're using is Alpine based, so you can't use apt-get because it's Ubuntu's package manager.

To fix this just use:

apk update and apk add

"D:\Program Files\Py\Scripts\pip.exe" install numpy -U

YOUR PATH to pip.exe in Python folder + install + YOUR LIB + -U

Hi, you can do something like that. This function deletes all spaces.

string delSpaces(string &str) 
{
   str.erase(std::remove(str.begin(), str.end(), ' '), str.end());
   return str;
}

I made another function, that deletes all unnecessary spaces.

string delUnnecessary(string &str)
{
    int size = str.length();
    for(int j = 0; j<=size; j++)
    {
        for(int i = 0; i <=j; i++)
        {
            if(str[i] == ' ' && str[i+1] == ' ')
            {
                str.erase(str.begin() + i);
            }
            else if(str[0]== ' ')
            {
                str.erase(str.begin());
            }
            else if(str[i] == '\0' && str[i-1]== ' ')
            {
                str.erase(str.end() - 1);
            }
        }
    }
    return str;
}

File file = new File(dir, "App.apk");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");
startActivity(intent);

I had the same problem and after several attempts, it worked out for me this way. I don't know why, but setting data and type separately screwed up my intent.

HTML

<div id="replaceMe">i need to be replaced</div>
<div id="iamReplacement">i am replacement</div>

JavaScript

jQuery('#replaceMe').replaceWith(jQuery('#iamReplacement'));

All the 'use UDP' answers assume an open network and 'stuff it as much as you can' approach. Good for old-style closed-garden dedicated audio/video networks, which are a vanishing sort.

In the actual world, your transmission will go through firewalls (that will drop multicast and sometimes udp), the network is shared with others more important ($$$) apps, so you want to punish abusers with window scaling.

In Oracle the solution would be:

UPDATE
    MasterTbl
SET
    (TotalX,TotalY,TotalZ) =
      (SELECT SUM(X),SUM(Y),SUM(Z)
         from DetailTbl where DetailTbl.MasterID = MasterTbl.ID)

Don't know if your system allows the same.

IRIs do not replace URIs, because only URIs (effectively, ASCII) are permissible in some contexts -- including HTTP.

Instead, you specify an IRI and it gets transformed into a URI when going out on the wire.

#import <TargetName-Swift.h>

you will see when you enter from keyboard #import < and after automaticly Xcode will advice to you.

This is the default working setup https://www.youtube.com/watch?v=XiD7JTCBdpI

Use Connection Method: standard TCP/IP over ssh

Then ssh hostname: 127.0.0.1:2222

SSH Username: vagrant password vagrant

MySQL Hostname: localhost

Username: homestead password:secret

I was looking at the same statistics problems. The approach you are thinking it is good and it will work. (Answer to the sorting has been given)

But in case you are interested in algorithm performance, I think there are a couple of algorithms that have better performance than just sorting the array, one (QuickSelect) is indicated by @bruce-feist's answer and is very well explained.

[Java implementation: https://discuss.leetcode.com/topic/14611/java-quick-select ]

But there is a variation of this algorithm named median of medians, you can find a good explanation on this link: http://austinrochford.com/posts/2013-10-28-median-of-medians.html

Java implementation of this: - https://stackoverflow.com/a/27719796/957979

Here's a short means I used to reduce the size of Images that have a high byteCount (basically pixels)

fun resizeImage(image: Bitmap): Bitmap {

    val width = image.width
    val height = image.height

    val scaleWidth = width / 10
    val scaleHeight = height / 10

    if (image.byteCount <= 1000000)
        return image

    return Bitmap.createScaledBitmap(image, scaleWidth, scaleHeight, false)
}

This returns a scaled Bitmap that is over 10 times smaller than the Bitmap passed as a parameter. Might not be the most ideal solution but it works.

Use 3 backslashes to escape spaces in names of directories:

scp user@host:/path/to/directory\\\ with\\\ spaces/file ~/Downloads

should copy to your Downloads directory the file from the remote directory called directory with spaces.

Easier method is window.location.href = "http://example.com/new_url";

But what if you want to check if username and password whether empty or not using JavaScript and send it to the php to check whether user in the database. You can do this easily following this code.

html form -

<form name="myForm" onsubmit="return validateForm()" method="POST" action="login.php" >         
    <input type="text" name="username" id="username" />
    <input type="password" name="password" id="password" />
    <input type="submit" name="submitBt"value="LogIn" />
</form>

javascript validation-

function validateForm(){
    var uname = document.forms["myForm"]["username"].value;
    var pass = document.forms["myForm"]["password"].value;

    if((!isEmpty(uname, "Log In")) && (!isEmpty(pass, "Password"))){

        return true;
    }else{
        return false;
    }
}

function isEmpty(elemValue, field){
    if((elemValue == "") || (elemValue == null)){
        alert("you can not have "+field+" field empty");
        return true;
    }else{
        return false;
    }
}

check if user in the database using php

<?php
    $con = mysqli_connect("localhost","root","1234","users");

    if(mysqli_connect_errno()){
        echo "Couldn't connect ".mysqli_connect_error();
    }else{
        //echo "connection successful <br />";
    }

    $uname_tb = $_POST['username'];
    $pass_tb = $_POST['password'];

    $query ="SELECT * FROM user";
    $result = mysqli_query($con,$query);

    while($row = mysqli_fetch_array($result)){
        if(($row['username'] == $uname_tb) && ($row['password'] == $pass_tb)){
            echo "Login Successful";
            header('Location: dashbord.php');
            exit();
        }else{
            echo "You are not in our database".mysqli_connect_error();
        }
    }
    mysqli_close($con);
?>

It looks like the class.phpmailer.php file is corrupt. I would download the latest version and try again.

I've always used phpMailer's SMTP feature:

$mail->IsSMTP();
$mail->Host = "localhost";

And if you need debug info:

$mail->SMTPDebug  = 2; // enables SMTP debug information (for testing)
                       // 1 = errors and messages
                       // 2 = messages only

The top one is a "power" operator, so in this case it is the same as 2 * 2 equal to is 2 to the power of 2. If you put a 3 in the middle position, you will see a difference.

In case you're using SharePoint 2010, using the following line of code will avoid having to reference the whole System.Web library:

Microsoft.SharePoint.Utilities.SPHttpUtility.HtmlEncode(stringToEncode);

I've impoved Jared's answer in my own manner:

    Function.prototype.clone = function() {
        var that = this;
        function newThat() {
            return (new that(
                arguments[0],
                arguments[1],
                arguments[2],
                arguments[3],
                arguments[4],
                arguments[5],
                arguments[6],
                arguments[7],
                arguments[8],
                arguments[9]
            ));
        }
        function __clone__() {
            if (this instanceof __clone__) {
                return newThat.apply(null, arguments);
            }
            return that.apply(this, arguments);
        }
        for(var key in this ) {
            if (this.hasOwnProperty(key)) {
                __clone__[key] = this[key];
            }
        }
        return __clone__;
    };

1) now it supports cloning of constructors (can call with new); in that case takes only 10 arguments (you can vary it) - due to impossibility of passing all arguments in original constructor

2) everything is in correct closures

In addition to --date=(relative|local|default|iso|iso-strict|rfc|short|raw), as others have mentioned, you can also use a custom log date format with

--date=format:'%Y-%m-%d %H:%M:%S'

This outputs something like 2016-01-13 11:32:13.

NOTE: If you take a look at the commit linked to below, I believe you'll need at least Git v2.6.0-rc0 for this to work.

In a full command it would be something like:

git config --global alias.lg "log --graph --decorate 
-30 --all --date-order --date=format:'%Y-%m-%d %H:%M:%S' 
--pretty=format:'%C(cyan)%h%Creset %C(black bold)%ad%Creset%C(auto)%d %s'" 

I haven't been able to find this in documentation anywhere (if someone knows where to find it, please comment) so I originally found the placeholders by trial and error.

In my search for documentation on this I found a commit to Git itself that indicates the format is fed directly to strftime. Looking up strftime (here or here) the placeholders I found match the placeholders listed.

The placeholders include:

%a      Abbreviated weekday name
%A      Full weekday name
%b      Abbreviated month name
%B      Full month name
%c      Date and time representation appropriate for locale
%d      Day of month as decimal number (01 – 31)
%H      Hour in 24-hour format (00 – 23)
%I      Hour in 12-hour format (01 – 12)
%j      Day of year as decimal number (001 – 366)
%m      Month as decimal number (01 – 12)
%M      Minute as decimal number (00 – 59)
%p      Current locale's A.M./P.M. indicator for 12-hour clock
%S      Second as decimal number (00 – 59)
%U      Week of year as decimal number, with Sunday as first day of week (00 – 53)
%w      Weekday as decimal number (0 – 6; Sunday is 0)
%W      Week of year as decimal number, with Monday as first day of week (00 – 53)
%x      Date representation for current locale
%X      Time representation for current locale
%y      Year without century, as decimal number (00 – 99)
%Y      Year with century, as decimal number
%z, %Z  Either the time-zone name or time zone abbreviation, depending on registry settings
%%      Percent sign

In a full command it would be something like

git config --global alias.lg "log --graph --decorate -30 --all --date-order --date=format:'%Y-%m-%d %H:%M:%S' --pretty=format:'%C(cyan)%h%Creset %C(black bold)%ad%Creset%C(auto)%d %s'" 

For me this simple command solved the problem:

sudo apt-get install postgresql postgresql-contrib libpq-dev python-dev

Then I can do:

 pip install psycopg2

For me the solution is to change Enable 32-bit Applications to False

None of the answers worked for me. So I'd like to share what I found after hours of research..

Keep seeing this message from event logs: The Module DLL C:\Windows\system32\RpcProxy\RpcProxy.dll failed to load. The data is the error. Turns out that dll is 64bit and cannot be loaded into 32bit process.

Because one moderator deleted my detailed image-supported answer on this question, just because I copied and pasted from another question, I am forced to put a less detailed answer and I will link the original answer if you want a more visual way to see the solution.

For Visual Studio 2019 and Visual Studio 2017 Users
For People who are missing this old feature in VS2019 (or maybe VS2017) from the old versions of Visual Studio

This feature still available, but it is NOT available by default, you have to install it separately.

1. Open VS 2019 go to Tools -> Get Tools and Features
2. Select the Individual components tab and search for Class Designer
3. Select this Component and Install it, After finish installing this component (you may need to restart visual studio)
4. Right-click on the project and select Add -> Add New Item
5. Search for 'class' word and NOW you can see Class Diagram component

Update to create a class-diagram for the whole project
I received a downvote because I did not mention how to generate a diagram for the whole project, here is how to do it (after applying the previous steps)

1. Add class diagram to the project
2. if the option Preview Selected Items is enabled in the solution explorer, disabled it temporarily, you can re-enable it later

3. open the class diagram that you created in step 2 (by double-clicking on it)
4. drag-and-drop the project from the solution explorer to the class diagram

you could be shocked by the results to the point that you can change your mind and remove your downvote (please do NOT upvote, it is enough to remove your downvote)

Unfortunately, all answers so far do not take into account that "a" must not be considered equal to "A" when it comes to sorting.

String[] array = {"b", "A", "C", "B", "a"};

// Approach 1
Arrays.sort(array);
// array is [A, B, C, a, b]

// Approach 2
Arrays.sort(array, String.CASE_INSENSITIVE_ORDER);
// array is [A, a, b, B, C]

// Approach 3
Arrays.sort(array, java.text.Collator.getInstance());
// array is [a, A, b, B, C]

In approach 1 any lower case letters are considered greater than any upper case letters.

Approach 2 makes it worse, since CASE_INSENSITIVE_ORDER considers "a" and "A" equal (comparation result is 0). This makes sorting non-deterministic.

Approach 3 (using a java.text.Collator) is IMHO the only way of doing it correctly, since it considers "a"and "A" not equal, but puts them in the correct order according to the current (or any other desired) Locale.

best way is to create an accessor like this:

/**
* @var object $db : map to database connection.
*/
public static $db= null; 

/**
* db Function for initializing variable.   
* @return object
*/
public static function db(){
 if( !isset(static::$db) ){
  static::$db= new \Helpers\MySQL( array(
    "hostname"=> "localhost",
    "username"=> "root",
    "password"=> "password",
    "database"=> "db_name"
    )
  );
 }
 return static::$db;
}

then you can do static::db(); or self::db(); from anywhere.

To complement the version of Leo Dabus, I added support for projects written Swift and Objective-C, also added support for the optional milliseconds, probably isn't the best but you would get the point:

Xcode 8 and Swift 3

        static let iso8601: DateFormatter = {
            let formatter = DateFormatter()

            formatter.locale = Locale(identifier: "en_US_POSIX")
            formatter.timeZone = TimeZone(secondsFromGMT: 0)
            formatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSXXXXX"
            return formatter

windowSoftInputMode will either pan or resize your activity layout. One thing that you can do is to attach an onFocusChanged listener to your EditText and when the user selects/taps the EditText then you hide or move your navigation buttons out of the screen. When the EditText loses focus then you can put the navigation buttons back at the bottom of the activity.

An obvious, but slow, mathematical approach is:

int firstDigit = (int)(i / Math.Pow(10, (int)Math.Log10(i))));

sshpass is broken if you try to use it inside a Sublime Text build target, inside a Makefile. Instead of sshpass, you can use passh: https://github.com/clarkwang/passh

With sshpass you would do:

sshpass -p pa$$word ssh user@host

With passh you would do:

passh -p pa$$word ssh user@host

Note: Do not forget to use -o StrictHostKeyChecking=no. Otherwise, the connection will hang on the first time you use it. For example:

passh -p pa$$word ssh -o StrictHostKeyChecking=no user@host
