The best solution is

1. set mysql's charset to 'utf-8'

2. do like this comment(add use_unicode=True and charset="utf8")

   db = MySQLdb.connect(host="localhost", user = "root", passwd = "", db = "testdb", use_unicode=True, charset="utf8") – KyungHoon Kim Mar 13 '14 at 17:04

        Create a connection to the database. It is strongly recommended
        that you only use keyword parameters. Consult the MySQL C API
        documentation for more information.

        host
          string, host to connect

        user
          string, user to connect as

        passwd
          string, password to use

        db
          string, database to use

        port
          integer, TCP/IP port to connect to

        unix_socket
          string, location of unix_socket to use

        conv
          conversion dictionary, see MySQLdb.converters

        connect_timeout
          number of seconds to wait before the connection attempt
          fails.

        compress
          if set, compression is enabled

        named_pipe
          if set, a named pipe is used to connect (Windows only)

        init_command
          command which is run once the connection is created

        read_default_file
          file from which default client values are read

        read_default_group
          configuration group to use from the default file

        cursorclass
          class object, used to create cursors (keyword only)

        use_unicode
          If True, text-like columns are returned as unicode objects
          using the connection's character set.  Otherwise, text-like
          columns are returned as strings.  columns are returned as
          normal strings. Unicode objects will always be encoded to
          the connection's character set regardless of this setting.

        charset
          If supplied, the connection character set will be changed
          to this character set (MySQL-4.1 and newer). This implies
          use_unicode=True.

        sql_mode
          If supplied, the session SQL mode will be changed to this
          setting (MySQL-4.1 and newer). For more details and legal
          values, see the MySQL documentation.

        client_flag
          integer, flags to use or 0
          (see MySQL docs or constants/CLIENTS.py)

        ssl
          dictionary or mapping, contains SSL connection parameters;
          see the MySQL documentation for more details
          (mysql_ssl_set()).  If this is set, and the client does not
          support SSL, NotSupportedError will be raised.

        local_infile
          integer, non-zero enables LOAD LOCAL INFILE; zero disables

        autocommit
          If False (default), autocommit is disabled.
          If True, autocommit is enabled.
          If None, autocommit isn't set and server default is used.

        There are a number of undocumented, non-standard methods. See the
        documentation for the MySQL C API for some hints on what they do.

I use the following snippet to view all the rows in a table. Use a query to find all the rows. The returned objects are the class instances. They can be used to view/edit the values as required:

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import create_engine, Sequence
from sqlalchemy import String, Integer, Float, Boolean, Column
from sqlalchemy.orm import sessionmaker

Base = declarative_base()

class MyTable(Base):
    __tablename__ = 'MyTable'
    id = Column(Integer, Sequence('user_id_seq'), primary_key=True)
    some_col = Column(String(500))

    def __init__(self, some_col):
        self.some_col = some_col

engine = create_engine('sqlite:///sqllight.db', echo=True)
Session = sessionmaker(bind=engine)
session = Session()

for class_instance in session.query(MyTable).all():
    print(vars(class_instance))

session.close()

\d is a digit, + is 1 or more, so a sequence of 1 or more digits

The following should work fine:

git diff -z --name-only commit1 commit2 | xargs -0 -IREPLACE rsync -aR REPLACE /home/changes/protected/

To explain further:

• The -z to with git diff --name-only means to output the list of files separated with NUL bytes instead of newlines, just in case your filenames have unusual characters in them.

• The -0 to xargs says to interpret standard input as a NUL-separated list of parameters.

• The -IREPLACE is needed since by default xargs would append the parameters to the end of the rsync command. Instead, that says to put them where the later REPLACE is. (That's a nice tip from this Server Fault answer.)

• The -a parameter to rsync means to preserve permissions, ownership, etc. if possible. The -R means to use the full relative path when creating the files in the destination.

Update: if you have an old version of xargs, you'll need to use the -i option instead of -I. (The former is deprecated in later versions of findutils.)

Standard C++ won't do much for you in this regard, since path names are platform-specific. You can manually parse the string (as in glowcoder's answer), use operating system facilities (e.g. http://msdn.microsoft.com/en-us/library/aa364232(v=VS.85).aspx ), or probably the best approach, you can use a third-party filesystem library like boost::filesystem.

You can edit your readme.md with instructions to install your laravel app in other environment like this:

## Create folders

```
#!terminal

cp .env.example .env && mkdir bootstrap/cache storage storage/framework && cd storage/framework && mkdir sessions views cache

```

## Folder permissions

```
#!terminal

sudo chown :www-data app storage bootstrap -R
sudo chmod 775 app storage bootstrap -R

```

## Install dependencies

```
#!terminal

composer install

```

It's possible with a lot of work.

Basically, you have to post likes action via the Open Graph API. Then, you can add a custom design to your like button.

But then, you''ll need to keep track yourself of the likes so a returning user will be able to unlike content he liked previously.

Plus, you'll need to ask user to log into your app and ask them the publish_action permission.

All in all, if you're doing this for an application, it may worth it. For a website where you basically want user to like articles, then this is really to much.

Also, consider that you increase your drop-off rate each time you ask user a permission via a Facebook login.

If you want to see an example, I've recently made an app using the open graph like button, just hover on some photos in the mosaique to see it

Change the onclick from

onclick="javascript:SubmitFrm()"

to

onclick="SubmitFrm()"

I don't see why you are grouping here.

Try this:

var maxValue = table.Max(x => x.Status)
var result = table.First(x => x.Status == maxValue);

An alternate approach that would iterate table only once would be this:

var result = table.OrderByDescending(x => x.Status).First();

This is helpful if table is an IEnumerable<T> that is not present in memory or that is calculated on the fly.

Swift 5 with Closure:

class ViewController: UIViewController {
    
var secondsRemaining = 30
    
@IBAction func startTimer(_ sender: UIButton) {
        
    Timer.scheduledTimer(withTimeInterval: 1.0, repeats: true) { (Timer) in
        if self.secondsRemaining > 0 {
            print ("\(self.secondsRemaining) seconds")
            self.secondsRemaining -= 1
        } else {
            Timer.invalidate()
        }
    }
            
}

This can be achieved by using constructor function instead of literal

var o = new function() {
  this.foo = "it";
  this.bar = this.foo + " works"
}

alert(o.bar)

Rob Heiser suggested checking out your java version by using 'java -version'.

That will identify the Java version that will be commonly found and used. Doing dev work, you can often have more than one version installed (I currently have 2 JREs - 6 and 7 - and may soon have 8).

http://www.coderanch.com/t/453224/java/java/java-version-work-setting-path

java -version will look for java.exe in the System32 directory in Windows. That's where a JRE will install it.

I'm assuming that IE either simply looks for java and that automatically starts checking in System32 or it'll use the path and hit whichever java.exe comes first in your path (if you tamper with the path to point to another JRE).

Also from what SLaks said, I would disagree with one thing. There is likely slightly better performance out of 64-it IE in 64-bit environments. So there is some reason for using it.

I was unable to use this answer because my linter won't allow unchecked casts.

Here is an alternative you can use. I feel it is actually a cleaner solution.

public <T> List<T> parseJsonArray(String json, Class<T> clazz) throws JsonProcessingException {
  var tree = objectMapper.readTree(json);
  var list = new ArrayList<T>();
  for (JsonNode jsonNode : tree) {
    list.add(objectMapper.treeToValue(jsonNode, clazz));
  }
  return list;
}

Like this:

for pet in pets :
  print(pet)

Add this at the start of main

ApplicationContext context = new ClassPathXmlApplicationContext("path/to/applicationContext.xml");

JobLauncher launcher=(JobLauncher)context.getBean("launcher");
Job job=(Job)context.getBean("job");

//Get as many beans you want
//Now do the thing you were doing inside test method
StopWatch sw = new StopWatch();
sw.start();
launcher.run(job, jobParameters);
sw.stop();
//initialize the log same way inside main
logger.info(">>> TIME ELAPSED:" + sw.prettyPrint());

If key isn't an int or float but a string, you need to convert it to an int first by doing

key = int(key)

or to a float by doing

key = float(key)

Otherwise, what you have in your question should work, but

if (key < 1) or (key > 34):

or

if not (1 <= key <= 34):

would be a bit clearer.

Create an intent to a ViewPerson activity and pass the PersonID (for a database lookup, for example).

Intent i = new Intent(getBaseContext(), ViewPerson.class);                      
i.putExtra("PersonID", personID);
startActivity(i);

Then in ViewPerson Activity, you can get the bundle of extra data, make sure it isn't null (in case if you sometimes don't pass data), then get the data.

Bundle extras = getIntent().getExtras();
if(extras !=null)
{
     personID = extras.getString("PersonID");
}

Now if you need to share data between two Activities, you can also have a Global Singleton.

public class YourApplication extends Application 
{     
     public SomeDataClass data = new SomeDataClass();
}

Then call it in any activity by:

YourApplication appState = ((YourApplication)this.getApplication());
appState.data.CallSomeFunctionHere(); // Do whatever you need to with data here.  Could be setter/getter or some other type of logic

Was just facing the same problem, java 8 on ubuntu

This usually happens when you edit the Homestead.yaml file.

If like me you tried homestead up --provision and didn't worked! then try this (it works for me):

• homestead destroy
• homestead up

.MERGE_MSG.swp is open in your git, you just need to delete this .swp file. In my case I used following command and it worked fine.

rm .MERGE_MSG.swp

This doesn't answer your question directly, but you can solve your problem with a one-liner:

find /tmp \( -name "*.pdf" -o -name "*.doc" \) -type f -exec rm {} +

Some versions of find (GNU, BSD) have a -delete action which you can use instead of calling rm:

find /tmp \( -name "*.pdf" -o -name "*.doc" \) -type f -delete

Adding comment for anyone using Plesk having issues with any of the above as it was driving me crazy, setting session.gc_maxlifetime from your PHP script wont work as Plesk has it's own garbage collection script run from cron.

I used the solution posted on the link below of moving the cron job from hourly to daily to avoid this issue, then the top answer above should work:

mv /etc/cron.hourly/plesk-php-cleanuper /etc/cron.daily/

Well, std::string is a class, const char * is a pointer. Those are two different things. It's easy to get from string to a pointer (since it typically contains one that it can just return), but for the other way, you need to create an object of type std::string.

My recommendation: Functions that take constant strings and don't modify them should always take const char * as an argument. That way, they will always work - with string literals as well as with std::string (via an implicit c_str()).

First you need to define the format of date column.

df['Date'] = pd.to_datetime(df.Date, format='%Y-%m-%d %H:%M:%S')

For your case base format can be set to;

df['Date'] = pd.to_datetime(df.Date, format='%Y-%m-%d')

After that you can set/change your desired output as follows;

df['Date'] = df['Date'].dt.strftime('%Y-%m-%d')

Use these properties in ImageView to keep aspect ratio:

android:adjustViewBounds="true"
android:scaleType="fitXY"

That directory is part of your user data and you can delete any user data without affecting Xcode seriously. You can delete the whole CoreSimulator/ directory. Xcode will recreate fresh instances there for you when you do your next simulator run. If you can afford losing any previous simulator data of your apps this is the easy way to get space.

Update: A related useful app is "DevCleaner for Xcode" https://apps.apple.com/app/devcleaner-for-xcode/id1388020431

Maybe I don't completely understand the accepted answer so it didn't work for me.

What i did was simply to check if the variable is null, assign it to a known value from my database. Which seems to be similar to the accepted answer whereby you first declare an known value and set it to selected

<select name="department">
    <c:forEach var="item" items="${dept}">
        <option value="${item.key}">${item.value}</option>
    </c:forEach>
</select>

because none of the options are selected, thus item = null

<%
    if(item == null){
        item = "selectedDept"; //known value from your database
    }
%>

This way if the user then selects another option, my IF clause will not catch it and assign to the fixed value that was declared at the start. My concept could be wrong here but it works for me

As Gary's Student mentioned, you would need to remove the dot before Cells to make the code work as you originally wrote it. I can't be sure, since you only included the one line of code, but the error you got when you deleted the dots might have something to do with how you defined your variables.

I ran your line of code with the variables defined as integers and it worked:

Sub TestClearLastColumn()

    Dim LastColData As Long
        Set LastColData = Range("A1").End(xlToRight).Column

    Dim LastRowData As Long
        Set LastRowData = Range("A1").End(xlDown).Row

    Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData)).ClearContents

End Sub

I don't think a With statement is appropriate to the line of code you shared, but if you were to use one, the With would be at the start of the line that defines the object you are manipulating. Here is your code rewritten using an unnecessary With statement:

With Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData))
    .ClearContents
End With

With statements are designed to save you from retyping code and to make your coding easier to read. It becomes useful and appropriate if you do more than one thing with an object. For example, if you wanted to also turn the column red and add a thick black border, you might use a With statement like this:

With Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData))
    .ClearContents
    .Interior.Color = vbRed
    .BorderAround Color:=vbBlack, Weight:=xlThick
End With

Otherwise you would have to declare the range for each action or property, like this:

    Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData)).ClearContents
    Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData)).Interior.Color = vbRed
    Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData)).BorderAround Color:=vbBlack, Weight:=xlThick

I hope this gives you a sense for why Gary's Student believed the compiler might be expecting a With (even though it was inappropriate) and how and when a With can be useful in your code.

You can do something like using join function of String class.

import java.util.Arrays;
import java.util.List;

public class Demo {

    public static void main(String[] args) {
        List<String> items = Arrays.asList("Java", "Ruby", "Python", "C++");
        String output = String.join(",", items);
        System.out.println(output);
    }

}

Use strlen to get the length of a null-terminated string.

sizeof returns the length of the array not the string. If it's a pointer (char *s), not an array (char s[]), it won't work, since it will return the size of the pointer (usually 4 bytes on 32-bit systems). I believe an array will be passed or returned as a pointer, so you'd lose the ability to use sizeof to check the size of the array.

So, only if the string spans the entire array (e.g. char s[] = "stuff"), would using sizeof for a statically defined array return what you want (and be faster as it wouldn't need to loop through to find the null-terminator) (if the last character is a null-terminator, you will need to subtract 1). If it doesn't span the entire array, it won't return what you want.

An alternative to all this is actually storing the size of the string.

This will return TRUE for #VALUE! errors (ERROR.TYPE = 3) and FALSE for anything else.

=IF(ISERROR(A1),ERROR.TYPE(A1)=3)

Basically the same solution as provided by Rutger Kassies, but using a more pythonic syntax:

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

data = np.arange(250, 260)

for ax, d in zip(axs.ravel(), data):
    ax.contourf(np.random.rand(10,10), 5, cmap=plt.cm.Oranges)
    ax.set_title(str(d))

.a files are static libraries typically generated by the archive tool. You usually include the header files associated with that static library and then link to the library when you are compiling.

Try this .... I got it... onClientClick="var b=validateView();if(b) var b=ShowDiv1();return b;"

The problem is that the execution policy is set on a per user basis. You'll need to run the following command in your application every time you run it to enable it to work:

Set-ExecutionPolicy -Scope Process -ExecutionPolicy RemoteSigned

There probably is a way to set this for the ASP.NET user as well, but this way means that you're not opening up your whole system, just your application.

Simple binary threshold method is sufficient.

include

#include <string>
#include "opencv/highgui.h"
#include "opencv2/imgproc/imgproc.hpp"

using namespace std;
using namespace cv;

int main()
{
    Mat img = imread("./img.jpg",0);//loading gray scale image
    threshold(img, img, 128, 255, CV_THRESH_BINARY);//threshold binary, you can change threshold 128 to your convenient threshold
    imwrite("./black-white.jpg",img);
    return 0;
}

You can use GaussianBlur to get a smooth black and white image.

protected void Page_Load(object sender, EventArgs e)
{
    myLabel.Text = "My text";
}

this is the base of ASP.Net, thinking in controls, not html flow.

Consider following a course, or reading a beginner book... and first, forget what you did in php :)

If you would like to replace but still keeping the style of previous str. It is possible.

For example: highlight the string "test asdasd TEST asd tEst asdasd".

sentence = "test asdasd TEST asd tEst asdasd"
result = re.sub(
  '(test)', 
  r'<b>\1</b>',  # \1 here indicates first matching group.
  sentence, 
  flags=re.IGNORECASE)

test asdasd TEST asd tEst asdasd

Using Android Studio newest version and update Android Plugin to 'newest alpha version`, I can disable Instant Run:

Try to update Android Studio.

>>> import math
>>> import numpy as np
>>> import scipy
>>> math.pi == np.pi == scipy.pi
True

So it doesn't matter, they are all the same value.

The only reason all three modules provide a pi value is so if you are using just one of the three modules, you can conveniently have access to pi without having to import another module. They're not providing different values for pi.

in Content script , i add script tag to the head which binds a 'onmessage' handler, inside the handler i use , eval to execute code. In booth content script i use onmessage handler as well , so i get two way communication. Chrome Docs

//Content Script

var pmsgUrl = chrome.extension.getURL('pmListener.js');
$("head").first().append("<script src='"+pmsgUrl+"' type='text/javascript'></script>");


//Listening to messages from DOM
window.addEventListener("message", function(event) {
  console.log('CS :: message in from DOM', event);
  if(event.data.hasOwnProperty('cmdClient')) {
    var obj = JSON.parse(event.data.cmdClient);
    DoSomthingInContentScript(obj);
 }
});

pmListener.js is a post message url listener

//pmListener.js

//Listen to messages from Content Script and Execute Them
window.addEventListener("message", function (msg) {
  console.log("im in REAL DOM");
  if (msg.data.cmnd) {
    eval(msg.data.cmnd);
  }
});

console.log("injected To Real Dom");

This way , I can have 2 way communication between CS to Real Dom. Its very usefull for example if you need to listen webscoket events , or to any in memory variables or events.

Expanding on Abdul's answer, you can obtain a KeyedTuple instead of a discrete collection of rows by joining the columns:

q = Session.query(*User.__table__.columns + Document.__table__.columns).\
        select_from(User).\
        join(Document, User.email == Document.author).\
        filter(User.email == 'someemail').all()

If you need to update the value in a particular table:

UPDATE TABLE-NAME SET COLUMN-NAME = REPLACE(TABLE-NAME.COLUMN-NAME, 'STRING-TO-REPLACE', 'REPLACEMENT-STRING');

where

  TABLE-NAME         - The name of the table being updated
  COLUMN-NAME        - The name of the column being updated
  STRING-TO-REPLACE  - The value to replace
  REPLACEMENT-STRING - The replacement

The limitation of execl is that when executing a shell command or any other script that is not in the current working directory, then we have to pass the full path of the command or the script. Example:

execl("/bin/ls", "ls", "-la", NULL);

The workaround to passing the full path of the executable is to use the function execlp, that searches for the file (1st argument of execlp) in those directories pointed by PATH:

execlp("ls", "ls", "-la", NULL);

When MySQL driver is used you have to set connection param rewriteBatchedStatements to true ( jdbc:mysql://localhost:3306/TestDB?**rewriteBatchedStatements=true**).

With this param the statement is rewritten to bulk insert when table is locked only once and indexes are updated only once. So it is much faster.

Without this param only advantage is cleaner source code.

Use worksheet.find (worksheet is your worksheet) and use the row-range for its range-object. You can get the rangeobject like: worksheet.rows(rowIndex) as example

Then give find the required parameters it should find it for you fine. If I recall correctly, find returns the first match per default. I have no Excel at hand, so you have to look up find for yourself, sorry

I would advise against using a for-loop it is more fragile and ages slower than find.

strINvalues = "1,1,2,2,3,3,4,4";
strINvalues = string.Join(",", strINvalues .Split(',').Distinct().ToArray());

Kkk Not sure if this is witchcraft or just beautiful code

1 strINvalues .Split(',').Distinct().ToArray()

2 string.Join(",", XXX);

1 Splitting the array and using Distinct [LINQ] to remove duplicates 2 Joining it back without the duplicates.

Sorry I never read the text on StackOverFlow just the code. it make more sense than the text ;)

Not sure the key combination that gets you there to the > prompt but it is not a bash prompt that I know. I usually get it by accident. Ctrl+C (or D) gets me back to the $ prompt.

I get this one all the time. It means that the user started to download a file, and then it either failed, or they cancelled it.

To reproduce the exception try do this yourself - however I'm unaware of any ways to prevent it (except for handling this specific exception only).

You need to decide what the best way forward is depending on your app.

Here is an answer based on that by Anubis (which is a better approach as it doesn't modify the headers for every request) but which is more equivalent to the code in the original question:

using Newtonsoft.Json;
...

var client = new HttpClient();
var httpRequestMessage = new HttpRequestMessage
    {
        Method = HttpMethod.Post,
        RequestUri = new Uri("https://api.clickatell.com/rest/message"),
        Headers = { 
            { HttpRequestHeader.Authorization.ToString(), "Bearer xxxxxxxxxxxxxxxxxxx" },
            { HttpRequestHeader.Accept.ToString(), "application/json" },
            { "X-Version", "1" }
        },
        Content = new StringContent(JsonConvert.SerializeObject(svm))
    };

var response = client.SendAsync(httpRequestMessage).Result;

Use this method:

Process.Start(String, String)

First argument is an application (explorer.exe), second method argument are arguments of the application you run.

For example:

in CMD:

explorer.exe -p

in C#:

Process.Start("explorer.exe", "-p")

A nice clean way to do this is to use View.SynchronizeClassView.

Additionally you can:

• pin your Class view window
• collapse the top pane (listing all the classes)

And now it feels just like the Visual Assist's feature "List Methods in Current File" (which also list members btw).

My two cents for this problem--I was having a similar issue with a chart on an Access 2010 report. I was dynamically building a querydef, setting that as the rowsource on my report and then trying to loop through each series and set the properties of each series. What I eventually had to do was to break out the querydef creation and the property setting into separate subs. Additionally, I put a

SendKeys ("{DOWN}")
SendKeys ("{UP}")

at the bottom of each of the two subs.

I used this below if this is what you are thinking. It it worked well for me.

<?php
    include $_SERVER['DOCUMENT_ROOT']."/head_lib.php";
?>

What I was trying to do was pulla file called /head_lib.php from the root folder. It would not pull anything to build the webpage. The header, footer and other key features in sub directories would never show up. Until I did above it worked like a champ.

Here's a one-liner (imports don't count :) that can easily be generalized to concatenate N dictionaries:

Python 3

from itertools import chain
dict(chain.from_iterable(d.items() for d in (d1, d2, d3)))

and:

from itertools import chain
def dict_union(*args):
    return dict(chain.from_iterable(d.items() for d in args))

Python 2.6 & 2.7

from itertools import chain
dict(chain.from_iterable(d.iteritems() for d in (d1, d2, d3))

Output:

>>> from itertools import chain
>>> d1={1:2,3:4}
>>> d2={5:6,7:9}
>>> d3={10:8,13:22}
>>> dict(chain.from_iterable(d.iteritems() for d in (d1, d2, d3)))
{1: 2, 3: 4, 5: 6, 7: 9, 10: 8, 13: 22}

Generalized to concatenate N dicts:

from itertools import chain
def dict_union(*args):
    return dict(chain.from_iterable(d.iteritems() for d in args))

I'm a little late to this party, I know, but I hope this helps someone.

Just click on form and go to JFrame properties, then Code tab and check Generate Center.

Sometimes, you really don't care about the collection itself. For instance, creating a simple model fit line to compare an "approximation" with the raw data:

fib_raw = [1, 1, 2, 3, 5, 8, 13, 21] # Fibonacci numbers

phi = (1 + sqrt(5)) / 2
phi2 = (1 - sqrt(5)) / 2

def fib_approx(n): return (phi**n - phi2**n) / sqrt(5)

x = range(len(data))
y = [fib_approx(n) for n in x]

# Now plot to compare fib_raw and y
# Compare error, etc

In this case, the values of the Fibonacci sequence itself were irrelevant. All we needed here was the size of the input sequence we were comparing with.

If you are using XAMPP as your server, you'll find a logs directory as a child of the XAMPP directory. If you have not tried XAMPP, which runs on any system (Windows, Mac OS & Linux) find more here: http://www.apachefriends.org/en/xampp.html

This error comes because compile does not know where to find the class..so it occurs mainly when u copy or import item ..to solve this .. 1.change the namespace in the formname.cs and formname.designer.cs to the name of your project .

I had the same problem of "Unable to ping server at localhost:1099" while I was using intellij 2016 version.

However, as soon as I upgraded it to 2017 version(Ultimate 2017.1) which is installed using "ideaIU-2017.1.exe" the problem disappeared.

Python's standard library has json and urllib2 modules.

Here's a nicely commented Image Manipulation helper class that you can look at and use. I wrote it as an example of how to perform certain image manipulation tasks in C#. You'll be interested in the ResizeImage function that takes a System.Drawing.Image, the width and the height as the arguments.

Update

A few people have been asking in the comments for samples of how to consume the ImageUtilities class, so here you go.

//resize the image to the specified height and width
using (var resized = ImageUtilities.ResizeImage(image, 50, 100))
{
    //save the resized image as a jpeg with a quality of 90
    ImageUtilities.SaveJpeg(@"C:\myimage.jpeg", resized, 90);
}

Note

Remember that images are disposable, so you need to assign the result of your resize to a using declaration (or you could use a try finally and make sure you call dispose in your finally).

One of my favorite uses of reflection is the below Java dump method. It takes any object as a parameter and uses the Java reflection API to print out every field name and value.

    callCount++;

    if (oClass.isArray()) {

        buffer.append(tabs.toString());
        buffer.append("[");
        for (int i = 0; i < Array.getLength(o); i++) {
            if (i < 0)
                buffer.append(",");
            Object value = Array.get(o, i);

        }
        buffer.append(tabs.toString());
        buffer.append("]\n");
    } else {
        buffer.append("\n");
        buffer.append(tabs.toString());

        while (oClass != null) {

                        }
                    }
                } catch (IllegalAccessException e) {

What about forking the parseInt method?

It's easy, just copy-paste the contents to a new utility that returns Integer or Optional<Integer> and replace throws with returns. It seems there are no exceptions in the underlying code, but better check.

By skipping the whole exception handling stuff, you can save some time on invalid inputs. And the method is there since JDK 1.0, so it is not likely you will have to do much to keep it up-to-date.

There are a lot of answers here that don't really address the basic fact that there's really NO WAY to do this predictably, and in a way that doesn't result you shooting yourself in the foot at some point in the future.

FragmentStatePagerAdapter is the only class that knows how to reliably access the fragments that are tracked by the FragmentManager - any attempt to try and guess the fragment's id or tag is not reliable, long-term. And attempts to track the instances manually will likely not work well when state is saved/restored, because FragmentStatePagerAdapter may well not call the callbacks when it restores the state.

About the only thing that I've been able to make work is copying the code for FragmentStatePagerAdapter and adding a method that returns the fragment, given a position (mFragments.get(pos)). Note that this method assumes that the fragment is actually available (i.e. it was visible at some point).

If you're particularly adventurous, you can use reflection to access the elements of the private mFragments list, but then we're back to square one (the name of the list is not guaranteed to stay the same).

If you are getting 'Enter Encryption Key' dialog box error:

I am using Swift 2.1 with Realm 0.96.2 and was getting this error when trying to open the database file:

'default' could not be opened. It may be encrypted, or it isn't in a compatible file format. If you know the file is encrypted, you can manually enter its encryption key to open it.

Found that using the pre-release version of the Realm Browser 0.96 fixed the issue:

https://github.com/realm/realm-browser-osx/releases/tag/0.96-prerelease

The OP says, for unknown reasons, "I prefer it without an arraylist or list."

If the type you are referring to is a primitive (you mention integers, but you don't say if you mean int or Integer), then you can use one of the NIO Buffer classes like java.nio.IntBuffer. These act a lot like StringBuffer does - they act as buffers for a list of the primitive type (buffers exist for all the primitives but not for Objects), and you can wrap a buffer around an array and/or extract an array from a buffer.

Note that the javadocs say, "The capacity of a buffer is never negative and never changes." It's still just a wrapper around an array, but one that's nicer to work with. The only way to effectively expand a buffer is to allocate() a larger one and use put() to dump the old buffer into the new one.

If it's not a primitive, you should probably just use List, or come up with a compelling reason why you can't or won't, and maybe somebody will help you work around it.

You may try Easy Python Decompiler. It's based on Decompyle++ and Uncompyle2. It's supports decompiling python versions 1.0-3.3

Note: I am the author of the above tool.

Use genfromtxt instead. It's a much more general method than loadtxt:

import numpy as np
print np.genfromtxt('col.txt',dtype='str')

Using the file col.txt:

foo bar
cat dog
man wine

This gives:

[['foo' 'bar']
 ['cat' 'dog']
 ['man' 'wine']]

If you expect that each row has the same number of columns, read the first row and set the attribute filling_values to fix any missing rows.

Since I do troubleshooting everyday as a part of my job, here is what I would like to do:

1. Since it's SQL Server 2008 R2, you can run SQLDiag which comes as a part of the product. You can refer books online for more details. In brief, capture Server Side trace and blocker script.

2. Once trace is captured, look for "Attention" event. That would be the spid which has received the error. If you filter by SPID, you would see RPC:Completed event before "Attention". Check the time over there. Is that time 30 seconds? If yes, then client waited for 30 second to get response from SQL and got "timed out" [This is client setting as SQL would never stop and connection]

3. Now, check if the query which was running really should take 30 seconds?

4. If yes then tune the query or increase the timeout setting from the client.

5. If no then this query must be waiting for some resources (blocked)

6. At this point go back to Blocker Script and check the time frame when "Attention" came

Above is assuming that issue is with SQL Server not network related!

You can use Runtime.getRuntime().addShutdownHook(...), but you cannot be guaranteed that it will be called in any case.

The problem seems that your python version and the library yoiu want to install is not matching versionally. Ex: If Django is Django3 and your python version is 2.7, you may get this error.

"After installing is running 'python' still ran Python 2.6 and PATH was not updated."

1- Install latest version of Python 2- Change your PATH manually as python38 and compare them. 3- Try to reinstall.

I solved this problem as replacing PATH manually with the latest version of Python. As for Windows: ;C:\python38\Scripts

I ended up adding a method setCurrentTimeout(int timeout) to the RetryPolicy and it's implementation in DefaultRetryPolicy.

Then I added a setCurrentTimeout(int timeout) in the Request class and called it .

This seems to do the job.

Sorry for my laziness by the way and hooray for open source.

You can use the -quit option of find:

find <dir> -maxdepth 1 -type d -name '*foo*' -print -quit

Open angular.json file and find budgets keyword.

It should look like:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "2mb",
          "maximumError": "5mb"
       }
    ]

As you’ve probably guessed you can increase the maximumWarning value to prevent this warning, i.e.:

    "budgets": [
       {
          "type": "initial",
          "maximumWarning": "4mb", <===
          "maximumError": "5mb"
       }
    ]

What does budgets mean?

A performance budget is a group of limits to certain values that affect site performance, that may not be exceeded in the design and development of any web project.

In our case budget is the limit for bundle sizes.

The HttpParams interface isn't there for specifying query string parameters, it's for specifying runtime behaviour of the HttpClient object.

If you want to pass query string parameters, you need to assemble them on the URL yourself, e.g.

new HttpGet(url + "key1=" + value1 + ...);

Remember to encode the values first (using URLEncoder).

You can use Series.isin:

df = df[~df.datecolumn.isin(a)]

While the error message suggests that all() or any() can be used, they are useful only when you want to reduce the result into a single Boolean value. That is however not what you are trying to do now, which is to test the membership of every values in the Series against the external list, and keep the results intact (i.e., a Boolean Series which will then be used to slice the original DataFrame).

You can read more about this in the Gotchas.

Declarations of public functions go in header files, yes, but definitions are absolutely valid in headers as well! You may declare the definition as static (only 1 copy allowed for the entire program) if you are defining things in a header for utility functions that you don't want to have to define again in each c file. I.E. defining an enum and a static function to translate the enum to a string. Then you won't have to rewrite the enum to string translator for each .c file that includes the header. :)

const countryResolver = (data = [{}]) => {
    const countrySelecter = document.createElement('select');
    countrySelecter.className = `custom-select`;
    countrySelecter.id = `countrySelect`;
    countrySelecter.setAttribute("aria-label", "Example select with button addon");

    let opt = document.createElement("option");
    opt.text = "Select language";
    opt.disabled = true;
    countrySelecter.add(opt, null);
    let i = 0;
    for (let item of data) {
        let opt = document.createElement("option");
        opt.value = item.Id;
        opt.text = `${i++}. ${item.Id} - ${item.Value}(${item.Comment})`;
        countrySelecter.add(opt, null);
    }
    return countrySelecter;
};

You can use names directly in the read_csv

names : array-like, default None List of column names to use. If file contains no header row, then you should explicitly pass header=None

Cov = pd.read_csv("path/to/file.txt", 
                  sep='\t',

I like this "real world" code example of pointer to pointer usage, in Git 2.0, commit 7b1004b:

Linus once said:

I actually wish more people understood the really core low-level kind of coding. Not big, complex stuff like the lockless name lookup, but simply good use of pointers-to-pointers etc.
For example, I've seen too many people who delete a singly-linked list entry by keeping track of the "prev" entry, and then to delete the entry, doing something like:

   if (prev)
     prev->next = entry->next;
   else
     list_head = entry->next;

and whenever I see code like that, I just go "This person doesn't understand pointers". And it's sadly quite common.

People who understand pointers just use a "pointer to the entry pointer", and initialize that with the address of the list_head. And then as they traverse the list, they can remove the entry without using any conditionals, by just doing a

*pp =  entry->next

Applying that simplification lets us lose 7 lines from this function even while adding 2 lines of comment.

- struct combine_diff_path *p, *pprev, *ptmp;
+ struct combine_diff_path *p, **tail = &curr;

Chris points out in the comments to the 2016 video "Linus Torvalds's Double Pointer Problem".

kumar points out in the comments the blog post "Linus on Understanding Pointers", where Grisha Trubetskoy explains:

Imagine you have a linked list defined as:

   typedef struct list_entry {
       int val;
       struct list_entry *next;
   } list_entry;

You need to iterate over it from the beginning to end and remove a specific element whose value equals the value of to_remove.
The more obvious way to do this would be:

   list_entry *entry = head; /* assuming head exists and is the first entry of the list */
   list_entry *prev = NULL;
   
   while (entry) { /* line 4 */
       if (entry->val == to_remove)     /* this is the one to remove ; line 5 */
           if (prev)
              prev->next = entry->next; /* remove the entry ; line 7 */
           else
               head = entry->next;      /* special case - first entry ; line 9 */
   
       /* move on to the next entry */
       prev = entry;
       entry = entry->next;
   }

What we are doing above is:

• iterating over the list until entry is NULL, which means we’ve reached the end of the list (line 4).
• When we come across an entry we want removed (line 5),
• we assign the value of current next pointer to the previous one,
• thus eliminating the current element (line 7).

There is a special case above - at the beginning of the iteration there is no previous entry (prev is NULL), and so to remove the first entry in the list you have to modify head itself (line 9).

What Linus was saying is that the above code could be simplified by making the previous element a pointer to a pointer rather than just a pointer.
The code then looks like this:

   list_entry **pp = &head; /* pointer to a pointer */
   list_entry *entry = head;

   while (entry) {
       if (entry->val == to_remove)
           *pp = entry->next;
       else
            pp = &entry->next;
       entry = entry->next;
   }

The above code is very similar to the previous variant, but notice how we no longer need to watch for the special case of the first element of the list, since pp is not NULL at the beginning. Simple and clever.

Also, someone in that thread commented that the reason this is better is because *pp = entry->next is atomic. It is most certainly NOT atomic.
The above expression contains two dereference operators (* and ->) and one assignment, and neither of those three things is atomic.
This is a common misconception, but alas pretty much nothing in C should ever be assumed to be atomic (including the ++ and -- operators)!

The unresponsive script dialog box shows when some javascript thread takes too long too complete. Editing the registry could work, but you would have to do it on all client machines. You could use a "recursive closure" as follows to alleviate the problem. It's just a coding structure in which allows you to take a long running for loop and change it into something that does some work, and keeps track where it left off, yielding to the browser, then continuing where it left off until we are done.

Figure 1, Add this Utility Class RepeatingOperation to your javascript file. You will not need to change this code:

RepeatingOperation = function(op, yieldEveryIteration) {

  //keeps count of how many times we have run heavytask() 
  //before we need to temporally check back with the browser.
  var count = 0;   

  this.step = function() {

    //Each time we run heavytask(), increment the count. When count
    //is bigger than the yieldEveryIteration limit, pass control back 
    //to browser and instruct the browser to immediately call op() so
    //we can pick up where we left off.  Repeat until we are done.
    if (++count >= yieldEveryIteration) {
      count = 0;

      //pass control back to the browser, and in 1 millisecond, 
      //have the browser call the op() function.  
      setTimeout(function() { op(); }, 1, [])

      //The following return statement halts this thread, it gives 
      //the browser a sigh of relief, your long-running javascript
      //loop has ended (even though technically we havn't yet).
      //The browser decides there is no need to alarm the user of
      //an unresponsive javascript process.
      return;
      }
    op();
  };
};

Figure 2, The following code represents your code that is causing the 'stop running this script' dialog because it takes so long to complete:

process10000HeavyTasks = function() {
  var len = 10000;  
  for (var i = len - 1; i >= 0; i--) {
    heavytask();   //heavytask() can be run about 20  times before
                   //an 'unresponsive script' dialog appears.
                   //If heavytask() is run more than 20 times in one
                   //javascript thread, the browser informs the user that
                   //an unresponsive script needs to be dealt with.  

                   //This is where we need to terminate this long running
                   //thread, instruct the browser not to panic on an unresponsive
                   //script, and tell it to call us right back to pick up
                   //where we left off.
  }
}

Figure 3. The following code is the fix for the problematic code in Figure 2. Notice the for loop is replaced with a recursive closure which passes control back to the browser every 10 iterations of heavytask()

process10000HeavyTasks = function() {

  var global_i = 10000; //initialize your 'for loop stepper' (i) here.

  var repeater = new this.RepeatingOperation(function() {

    heavytask();

    if (--global_i >= 0){     //Your for loop conditional goes here.
      repeater.step();        //while we still have items to process,
                              //run the next iteration of the loop.
    }
    else {
       alert("we are done");  //when this line runs, the for loop is complete.
    }
  }, 10);                   //10 means process 10 heavytask(), then
                            //yield back to the browser, and have the
                            //browser call us right back.

  repeater.step();          //this command kicks off the recursive closure.

};

In webforms you could also render almost whole html by hand, except few tags like viewstate, eventvalidation and similar, which can be removed with PageAdapters. Nobody force you to use GridView or some other server side control that has bad html rendering output.

I would say that biggest advantage of MVC is SPEED!

Next is forced separation of concern. But it doesn't forbid you to put whole BL and DAL logic inside Controller/Action! It's just separation of view, which can be done also in webforms (MVP pattern for example). A lot of things that people mentions for mvc can be done in webforms, but with some additional effort.
Main difference is that request comes to controller, not view, and those two layers are separated, not connected via partial class like in webforms (aspx + code behind)

An undirected graph is acyclic (i.e., a forest) if a DFS yields no back edges. Since back edges are those edges (u, v) connecting a vertex u to an ancestor v in a depth-first tree, so no back edges means there are only tree edges, so there is no cycle. So we can simply run DFS. If find a back edge, there is a cycle. The complexity is O(V) instead of O(E + V). Since if there is a back edge, it must be found before seeing |V| distinct edges. This is because in a acyclic (undirected) forest, |E| = |V| + 1.

I have a feeling that the username and password that you are sending should be part of the Authorization Header. So the code below shows you how to create the Base64 string of the username and password. I also included an example of sending the POST data. In my case it was a phone_number parameter.

string credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(_username + ":" + _password));

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(Request);
webRequest.Headers.Add("Authorization", string.Format("Basic {0}", credentials));
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = WebRequestMethods.Http.Post;
webRequest.AllowAutoRedirect = true;
webRequest.Proxy = null;

string data = "phone_number=19735559042"; 
byte[] dataStream = Encoding.UTF8.GetBytes(data);

request.ContentLength = dataStream.Length;
Stream newStream = webRequest.GetRequestStream();
newStream.Write(dataStream, 0, dataStream.Length);
newStream.Close();

HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse();
Stream stream = response.GetResponseStream();
StreamReader streamreader = new StreamReader(stream);
string s = streamreader.ReadToEnd();

Here is a class I use when writing services. I usually have an interactive screen that comes up when the service is not called. From there I use the class as needed. It allows for multiple named instances on the same machine -hence the InstanceID field

Sample Call

  IntegratedServiceInstaller Inst = new IntegratedServiceInstaller();
  Inst.Install("MySvc", "My Sample Service", "Service that executes something",
                    _InstanceID,
// System.ServiceProcess.ServiceAccount.LocalService,      // this is more secure, but only available in XP and above and WS-2003 and above
  System.ServiceProcess.ServiceAccount.LocalSystem,       // this is required for WS-2000
  System.ServiceProcess.ServiceStartMode.Automatic);
  if (controller == null)
  {
    controller = new System.ServiceProcess.ServiceController(String.Format("MySvc_{0}", _InstanceID), ".");
                }
                if (controller.Status == System.ServiceProcess.ServiceControllerStatus.Running)
                {
                    Start_Stop.Text = "Stop Service";
                    Start_Stop_Debugging.Enabled = false;
                }
                else
                {
                    Start_Stop.Text = "Start Service";
                    Start_Stop_Debugging.Enabled = true;
                }

From Browser/Client perspective

JSP and JSF both looks same, As Per Application Requirements goes, JSP is more suited for request - response based applications.

JSF is targetted for richer event based Web applications. I see event as much more granular than request/response.

From Server Perspective

JSP page is converted to servlet, and it has only minimal behaviour.

JSF page is converted to components tree(by specialized FacesServlet) and it follows component lifecycle defined by spec.

This should work fine.

    Workbook wb = new XSSFWorkbook("myWorkbook.xlsx");
    Row row=sheet.getRow(0);
    CellStyle style=null;

    XSSFFont defaultFont= wb.createFont();
    defaultFont.setFontHeightInPoints((short)10);
    defaultFont.setFontName("Arial");
    defaultFont.setColor(IndexedColors.BLACK.getIndex());
    defaultFont.setBold(false);
    defaultFont.setItalic(false);

    XSSFFont font= wb.createFont();
    font.setFontHeightInPoints((short)10);
    font.setFontName("Arial");
    font.setColor(IndexedColors.WHITE.getIndex());
    font.setBold(true);
    font.setItalic(false);

    style=row.getRowStyle();
    style.setFillBackgroundColor(IndexedColors.DARK_BLUE.getIndex());
    style.setFillPattern(CellStyle.SOLID_FOREGROUND);
    style.setAlignment(CellStyle.ALIGN_CENTER);
    style.setFont(font);

If you do not create defaultFont all your workbook will be using the other one as default.

                await client.SendAsync(email).ConfigureAwait(false);
                await client.DisconnectAsync(true).ConfigureAwait(false);
            }
        }
    }
}

The fundamental difference between include and import is that you must use import to refer to declarations or definitions that are in a different target namespace and you must use include to refer to declarations or definitions that are (or will be) in the same target namespace.

Is this what you need?

DataTable myDataTable = new DataTable();
List<int> myList = new List<int>();
foreach (DataRow row in myDataTable.Rows)
{
    myList.Add((int)row[0]);
}

Using display: flex you can control the vertical alignment of HTML elements.

.box {_x000D_
  height: 100px;_x000D_
  display: flex;_x000D_
  align-items: center; /* Vertical */_x000D_
  justify-content: center; /* Horizontal */_x000D_
  border:2px solid black;_x000D_
}_x000D_
_x000D_
.box div {_x000D_
  width: 100px;_x000D_
  height: 20px;_x000D_
  border:1px solid;_x000D_
}

<div class="box">_x000D_
  <div>Hello</div>_x000D_
  <p>World</p>_x000D_
</div>

There are two ways to add references via VBA to your projects

1) Using GUID

2) Directly referencing the dll.

Let me cover both.

But first these are 3 things you need to take care of

a) Macros should be enabled

b) In Security settings, ensure that "Trust Access To Visual Basic Project" is checked

c) You have manually set a reference to `Microsoft Visual Basic for Applications Extensibility" object

Way 1 (Using GUID)

I usually avoid this way as I have to search for the GUID in the registry... which I hate LOL. More on GUID here.

Topic: Add a VBA Reference Library via code

Link: http://www.vbaexpress.com/kb/getarticle.php?kb_id=267

'Credits: Ken Puls
Sub AddReference()
     'Macro purpose:  To add a reference to the project using the GUID for the
     'reference library

    Dim strGUID As String, theRef As Variant, i As Long

     'Update the GUID you need below.
    strGUID = "{00020905-0000-0000-C000-000000000046}"

     'Set to continue in case of error
    On Error Resume Next

     'Remove any missing references
    For i = ThisWorkbook.VBProject.References.Count To 1 Step -1
        Set theRef = ThisWorkbook.VBProject.References.Item(i)
        If theRef.isbroken = True Then
            ThisWorkbook.VBProject.References.Remove theRef
        End If
    Next i

     'Clear any errors so that error trapping for GUID additions can be evaluated
    Err.Clear

     'Add the reference
    ThisWorkbook.VBProject.References.AddFromGuid _
    GUID:=strGUID, Major:=1, Minor:=0

     'If an error was encountered, inform the user
    Select Case Err.Number
    Case Is = 32813
         'Reference already in use.  No action necessary
    Case Is = vbNullString
         'Reference added without issue
    Case Else
         'An unknown error was encountered, so alert the user
        MsgBox "A problem was encountered trying to" & vbNewLine _
        & "add or remove a reference in this file" & vbNewLine & "Please check the " _
        & "references in your VBA project!", vbCritical + vbOKOnly, "Error!"
    End Select
    On Error GoTo 0
End Sub

Way 2 (Directly referencing the dll)

This code adds a reference to Microsoft VBScript Regular Expressions 5.5

Option Explicit

Sub AddReference()
    Dim VBAEditor As VBIDE.VBE
    Dim vbProj As VBIDE.VBProject
    Dim chkRef As VBIDE.Reference
    Dim BoolExists As Boolean

    Set VBAEditor = Application.VBE
    Set vbProj = ActiveWorkbook.VBProject

    '~~> Check if "Microsoft VBScript Regular Expressions 5.5" is already added
    For Each chkRef In vbProj.References
        If chkRef.Name = "VBScript_RegExp_55" Then
            BoolExists = True
            GoTo CleanUp
        End If
    Next

    vbProj.References.AddFromFile "C:\WINDOWS\system32\vbscript.dll\3"

CleanUp:
    If BoolExists = True Then
        MsgBox "Reference already exists"
    Else
        MsgBox "Reference Added Successfully"
    End If

    Set vbProj = Nothing
    Set VBAEditor = Nothing
End Sub

Note: I have not added Error Handling. It is recommended that in your actual code, do use it :)

EDIT Beaten by mischab1 :)

$ git checkout stash@{0} -- <filename>

Notes:

1. Make sure you put space after the "--" and the file name parameter

2. Replace zero(0) with your specific stash number. To get stash list, use:

   git stash list
   

Based on Jakub Narebski's answer -- Shorter version

You first have to tell Gnuplot to use a style that uses points, e.g. with points or with linespoints. Try for example:

plot sin(x) with points

Output:

Now try:

plot sin(x) with points pointtype 5

Output:

You may also want to look at the output from the test command which shows you the capabilities of the current terminal. Here are the capabilities for my pngairo terminal:

TLDR: Aggregation pipeline is faster as compared to conventional .find().sort().

Now moving to the real explanation. There are two ways to perform sorting operations in MongoDB:

1. Using .find() and .sort().
2. Or using the aggregation pipeline.

As suggested by many .find().sort() is the simplest way to perform the sorting.

.sort([("field1",pymongo.ASCENDING), ("field2",pymongo.DESCENDING)])

However, this is a slow process compared to the aggregation pipeline.

Coming to the aggregation pipeline method. The steps to implement simple aggregation pipeline intended for sorting are:

1. $match (optional step)
2. $sort

NOTE: In my experience, the aggregation pipeline works a bit faster than the .find().sort() method.

Here's an example of the aggregation pipeline.

db.collection_name.aggregate([{
    "$match": {
        # your query - optional step
    }
},
{
    "$sort": {
        "field_1": pymongo.ASCENDING,
        "field_2": pymongo.DESCENDING,
        ....
    }
}])

Try this method yourself, compare the speed and let me know about this in the comments.

Edit: Do not forget to use allowDiskUse=True while sorting on multiple fields otherwise it will throw an error.

You got the return values the wrong way round:

• As soon as you find two values that are equal, you can conclude that the array is not unique and return false.

• At the very end, after you've checked all the pairs, you can return true.

If you do this a lot, and the arrays are large, you might want to investigate the possibility of sorting the array and then only comparing adjacent elements. This will have better asymptotic complexity than your current method.

Insert this code in your .htaccess file. And it should work

RewriteCond %{HTTP_HOST} yourDomainName\.com [NC]
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://yourDomainName.com/$1 [R,L]

I know its very late to answer this but hope this may help anyone.

you can create button like radio button using IBOutletCollection. create one IBOutletCollection property in our .h file.

@property (nonatomic, strong) IBOutletCollection(UIButton) NSArray *ButtonArray;

connect all button with this IBOutletCollection and make one IBAction method for all three button.

- (IBAction)btnTapped:(id)sender {
       for ( int i=0; i < [self.ButtonArray count]; i++) {
           [[self.ButtonArray objectAtIndex:i] setImage:[UIImage                         
            imageNamed:@"radio-off.png"]                 
            forState:UIControlStateNormal];
       }
     [sender setImage:[UIImage imageNamed:@"radio-on.png"]
      forState:UIControlStateNormal];
}

this worked for me for c#

if (enableEndDateCheckBox.Checked == true)
{
    endDateDateTimePicker.Enabled = true;
    endDateDateTimePicker.Format = DateTimePickerFormat.Short;                
}
else
{
    endDateDateTimePicker.Enabled = false;
    endDateDateTimePicker.Format = DateTimePickerFormat.Custom;
    endDateDateTimePicker.CustomFormat = " ";
}

nice one guys!

This might be old but somebody might get help through this. I too faced the same problem and received a mail on my gmail account stating that someone is trying to hack your account through an email client or a different site. THen I searched and found that doing below would resolve this issue.

Go to https://accounts.google.com/UnlockCaptcha? and unlock your account for access through other media/sites.

UPDATE : 2015

Also, you can try this, Go to https://myaccount.google.com/security#connectedapps At the bottom, towards right there is an option "Allow less secure apps". If it is "OFF", turn it on by sliding the button.

android only use linux kernel, that means the GNU tool chain like gcc as are not implemented in android, so if you want run a linux app in android, you need recompile it with google's tool chain( NDK ).

Normally this error occurs when you invoke java by supplying the wrong arguments/options. In this case it should be the version option.

java -version

So to double check you can always do java -help, and see if the option exists. In this case, there is no option such as v.

It's also possible to select attributes regardless of their content, in modern browsers

with:

[data-my-attribute] {
   /* Styles */
}

[anything] {
   /* Styles */
}

For example: http://codepen.io/jasonm23/pen/fADnu

Works on a very significant percentage of browsers.

Note this can also be used in a JQuery selector, or using document.querySelector

Question still relevant as of Android Studio 3.5.2 for Windows.

In my specific use case, I was trying to add Gander (https://github.com/Ashok-Varma/Gander) to my list of dependencies when I keep getting this particular headache.

It turns out that I have yet to get JCenter Certificate approved in my cacerts file. I'm going through a company firewall and i had to do this with dependencies that I attempt to import. Thus, to do so:

1. Ensure that your Android Studio does not need to go through any proxy.

2. Export the certificate where you get your dependency (usually just JCenter)

3. Add the certificate to your cacerts file:

   keytool -import -alias [your-certificate-name] -keystore 'C:\Program Files\Java\jdk[version]\jre\lib\security\cacerts' -file [absolute\path\to\your\certificate].cer

4. Restart Android Studio

5. Try syncing again.

Answer is based on this one: https://stackoverflow.com/a/26183328/4972380

It’s because you tried to update a table without a WHERE that uses a KEY column.

The quick fix is to add SET SQL_SAFE_UPDATES=0; before your query :

SET SQL_SAFE_UPDATES=0; 

Or

close the safe update mode. Edit -> Preferences -> SQL Editor -> SQL Editor remove Forbid UPDATE and DELETE statements without a WHERE clause (safe updates) .

BTW you can use TRUNCATE TABLE tablename; to delete all the records .

here is a simple solution. the problem is because you are using latest version for one library and lower version for the other library. try to balance it. the best solution is to use latest version for all of your libraries. To solve your problem simply click here and see the latest version of libraries and include it in you project and then synchronize it.
in my case the following is working for me:

dependencies{
    implementation 'com.google.firebase:firebase-core:16.0.7'
    implementation 'com.google.firebase:firebase-database:16.1.0'
}
apply plugin: 'com.google.gms.google-services'

In over simplified terms a web service is something that provides data as a service over the http protocol. Granted that isn't alway the case....but it is close.

Standard Web Services use The SOAP protocol which defines the communication and structure of messages, and XML is the data format.

Web services are designed to allow applications built using different technologies to communicate with each other without issues.

Examples of web services are things like Weather.com providing weather information for that you can use on your site, or UPS providing a method to request shipping quotes or tracking of packages.

Edit

Changed wording in reference to SOAP, as it is not always SOAP as I mentioned, but wanted to make it more clear. The key is providing data as a service, not a UI element.

The exception message says you're trying to connect to the same host (127.0.0.1), while you're stating that your server is running on a different host. Besides the obvious bugs like having "localhost" in the url, or maybe some you might want to check your DNS settings.

https://docs.oracle.com/javase/tutorial/reflect/class/classMembers.html also has charts for locating methods and constructors.

You've got an array of objects, so you'll need to use ng-repeat twice, like:

<ul ng-repeat="item in items">
  <li ng-repeat="(key, val) in item">
    {{key}}: {{val}}
  </li>
</ul>

Example: http://jsfiddle.net/Vwsej/

Edit:

Note that properties order in objects are not guaranteed.

<table>
    <tr>
        <th ng-repeat="(key, val) in items[0]">{{key}}</th>
    </tr>
    <tr ng-repeat="item in items">
        <td ng-repeat="(key, val) in item">{{val}}</td>
    </tr>
</table>

Example: http://jsfiddle.net/Vwsej/2/

I would always use sp_executesql these days, all it really is is a wrapper for EXEC which handles parameters & variables.

However do not forget about OPTION RECOMPILE when tuning queries on very large databases, especially where you have data spanned over more than one database and are using a CONSTRAINT to limit index scans.

Unless you use OPTION RECOMPILE, SQL server will attempt to create a "one size fits all" execution plan for your query, and will run a full index scan each time it is run.

This is much less efficient than a seek, and means it is potentially scanning entire indexes which are constrained to ranges which you are not even querying :@

If this JSON file won't become too big over time, you should try:

1. Create a JavaScript object with the table array in it

   var obj = {
      table: []
   };
   

2. Add some data to it, for example:

   obj.table.push({id: 1, square:2});
   

3. Convert it from an object to a string with JSON.stringify

   var json = JSON.stringify(obj);
   

4. Use fs to write the file to disk

   var fs = require('fs');
   fs.writeFile('myjsonfile.json', json, 'utf8', callback);
   

5. If you want to append it, read the JSON file and convert it back to an object

   fs.readFile('myjsonfile.json', 'utf8', function readFileCallback(err, data){
       if (err){
           console.log(err);
       } else {
       obj = JSON.parse(data); //now it an object
       obj.table.push({id: 2, square:3}); //add some data
       json = JSON.stringify(obj); //convert it back to json
       fs.writeFile('myjsonfile.json', json, 'utf8', callback); // write it back 
   }});
   

This will work for data that is up to 100 MB effectively. Over this limit, you should use a database engine.

UPDATE:

Create a function which returns the current date (year+month+day) as a string. Create the file named this string + .json. the fs module has a function which can check for file existence named fs.stat(path, callback). With this, you can check if the file exists. If it exists, use the read function if it's not, use the create function. Use the date string as the path cuz the file will be named as the today date + .json. the callback will contain a stats object which will be null if the file does not exist.

Assuming you're on Windows (if so you should tag your question as such!), on this MSDN page you can find the source for a simple, useful HRTimer C++ class that wraps the needed system calls to do something very close to what you require (it would be easy to add a GetTicks() method to it, in particular, to do exactly what you require).

On non-Windows platforms, there's no QueryPerformanceCounter function, so the solution won't be directly portable. However, if you do wrap it in a class such as the above-mentioned HRTimer, it will be easier to change the class's implementation to use what the current platform is indeed able to offer (maybe via Boost or whatever!).

To set it programmatically in Activity.java:

public void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  setTheme(R.style.MyTheme); // (for Custom theme)
  setTheme(android.R.style.Theme_Holo); // (for Android Built In Theme)

  this.setContentView(R.layout.myactivity);

To set in Application scope in Manifest.xml (all activities):

 <application
    android:theme="@android:style/Theme.Holo"
    android:theme="@style/MyTheme">

To set in Activity scope in Manifest.xml (single activity):

  <activity
    android:theme="@android:style/Theme.Holo"
    android:theme="@style/MyTheme">

To build a custom theme, you will have to declare theme in themes.xml file, and set styles in styles.xml file.

All answers describe specific cases, but there is a general answer:

You call the dtor explicitly every time you need to just destroy the object (in C++ sense) without releasing the memory the object resides in.

This typically happens in all the situation where memory allocation / deallocation is managed independently from object construction / destruction. In those cases construction happens via placement new upon an existent chunk of memory, and destruction happens via explicit dtor call.

Here is the raw example:

{
  char buffer[sizeof(MyClass)];

  {
     MyClass* p = new(buffer)MyClass;
     p->dosomething();
     p->~MyClass();
  }
  {
     MyClass* p = new(buffer)MyClass;
     p->dosomething();
     p->~MyClass();
  }

}

Another notable example is the default std::allocator when used by std::vector: elements are constructed in vector during push_back, but the memory is allocated in chunks, so it pre-exist the element contruction. And hence, vector::erase must destroy the elements, but not necessarily it deallocates the memory (especially if new push_back have to happen soon...).

It is "bad design" in strict OOP sense (you should manage objects, not memory: the fact objects require memory is an "incident"), it is "good design" in "low level programming", or in cases where memory is not taken from the "free store" the default operator new buys in.

It is bad design if it happens randomly around the code, it is good design if it happens locally to classes specifically designed for that purpose.

man wget: -O file --output-document=file

wget "url" -O /tmp/cron_test/<file>

To resolve I did the following:

1. Copied sqljdbc_auth.dll into dir: C:\Windows\System32
2. Restarted my application

In newer versions of CMake you can set compiler and linker flags for a single target with target_compile_options and target_link_libraries respectively (yes, the latter sets linker options too):

target_compile_options(first-test PRIVATE -fexceptions)

The advantage of this method is that you can control propagation of options to other targets that depend on this one via PUBLIC and PRIVATE.

As of CMake 3.13 you can also use target_link_options to add linker options which makes the intent more clear.

This is one solution. If you want to make it more generic, you can use the StringUtils library.

String value = "{first_name = naresh,last_name = kumar,gender = male}";
value = value.substring(1, value.length()-1);           //remove curly brackets
String[] keyValuePairs = value.split(",");              //split the string to creat key-value pairs
Map<String,String> map = new HashMap<>();               

for(String pair : keyValuePairs)                        //iterate over the pairs
{
    String[] entry = pair.split("=");                   //split the pairs to get key and value 
    map.put(entry[0].trim(), entry[1].trim());          //add them to the hashmap and trim whitespaces
}

For example you can switch

 value = value.substring(1, value.length()-1);

to

 value = StringUtils.substringBetween(value, "{", "}");

if you are using StringUtils which is contained in apache.commons.lang package.

You need a gutter between two div gutter can be made as following

margin(gutter) = width - gutter size E.g margin = calc(70% - 2em)

<body bgcolor="gray">
<section id="main">
        <div id="left">
            Something here     
        </div>
        <div id="right">
                Someone there
        </div>
</section>
</body>
<style>
body{
    font-size: 10px;
}

#main div{
    float: left;
    background-color:#ffffff;
    width: calc(50% - 1.5em);
    margin-left: 1.5em;
}
</style>

This was my solution after a lot of struggling to reduce the rating bar in small size without even ugly padding

 <RatingBar
        android:id="@+id/listitemrating"
        style="@android:attr/ratingBarStyleSmall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:scaleX=".5"
        android:scaleY=".5"
        android:transformPivotX="0dp"
        android:transformPivotY="0dp"
        android:isIndicator="true"
        android:max="5" />

Create a branch on the local system with that name. e.g. say you want to get the branch named branch-05142011

git branch branch-05142011 origin/branch-05142011

It'll give you a message:

$ git checkout --track origin/branch-05142011
Branch branch-05142011 set up to track remote branch refs/remotes/origin/branch-05142011.
Switched to a new branch "branch-05142011"

Now just checkout the branch like below and you have the code

git checkout branch-05142011

Just add this class in your css

.column p{
   text-align:center;
}

I know I'm late to the game... but the solution you're looking for might be the combination of the above, and using an interface to define your objects publicly accessible aspects.

Then, if all of your classes that would be generated this way implement that interface, you can just cast as the interface type and work with the resulting object.

Option 1 is to use display:table-cell. You need to unfloat the Bootstrap col-* using float:none..

.center {
    display:table-cell;
    vertical-align:middle;
    float:none;
}

http://bootply.com/94394

Option 2 is display:flex to vertical align the row with flexbox:

.row.center {
   display: flex;
   align-items: center;
}

http://www.bootply.com/7rAuLpMCwr

Vertical centering is very different in Bootstrap 4. See this answer for Bootstrap 4 https://stackoverflow.com/a/41464397/171456

For multiple elements, you should give it a class rather than id eg:

<input type="text" class="task" name="task[]" />

Now you can get those using jquery something like this:

$('.task').each(function(){
   alert($(this).val());
});

Right. So I've finally got to the bottom of the problem: it was a botched in-place OTA upgrade.

My suspicions intensified after my Garmin Fenix 2 wasn't able to connect via bluetooth and after googling "Marshmallow upgrade issues". Anyway, a "Factory reset" fixed the issue.

Surprisingly, the reset did not return the phone to the original Kitkat; instead, the wipe process picked up the OTA downloaded 6.0 upgrade package and ran with it, resulting (I guess) in a "cleaner" upgrade.

Of course, this meant that the phone lost all the apps that I'd installed. But, freshly installed apps, including mine, work without any changes (i.e. there is backward compatibility). Whew!

The following works fine for me in Excel 2007. It is simple, and performs a full copy (retains all formatting, etc.):

Sheets("Sheet1").Columns(1).Copy Destination:=Sheets("Sheet2").Columns(2)

"Columns" returns a Range object, and so this is utilizing the "Range.Copy" method. "Destination" is an option to this method - if not provided the default is to copy to the paste buffer. But when provided, it is an easy way to copy.

As when manually copying items in Excel, the size and geometry of the destination must support the range being copied.

You can initialize a Dictionary (and other collections) inline. Each member is contained with braces:

Dictionary<int, StudentName> students = new Dictionary<int, StudentName>
{
    { 111, new StudentName { FirstName = "Sachin", LastName = "Karnik", ID = 211 } },
    { 112, new StudentName { FirstName = "Dina", LastName = "Salimzianova", ID = 317 } },
    { 113, new StudentName { FirstName = "Andy", LastName = "Ruth", ID = 198 } }
};

See Microsoft Docs for details.

If you have a toggle switch that toggles between list to grid, don't forget to call recyclerView.removeItemDecoration() before setting any new Item decoration. If not then the new calculations for the spacing would be incorrect.

Something like this.

        recyclerView.removeItemDecoration(gridItemDecorator)
        recyclerView.removeItemDecoration(listItemDecorator)
        if (showAsList){
            recyclerView.layoutManager = LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false)
            recyclerView.addItemDecoration(listItemDecorator)
        }
        else{
            recyclerView.layoutManager = GridLayoutManager(this, spanCount)
            recyclerView.addItemDecoration(gridItemDecorator)
        }

With regards to @CrazyJugglerDrummer second method it would be:

elementsToChange.style.cursor = "http://wiki-devel.sugarlabs.org/images/e/e2/Arrow.cur";

def valid = pointAddress.findAll { a ->
    validPointTypes.any { a.contains(it) }
}

Should do it

I wrote this pattern:

Pattern SPECIAL_REGEX_CHARS = Pattern.compile("[{}()\\[\\].+*?^$\\\\|]");

And use it in this method:

String escapeSpecialRegexChars(String str) {

    return SPECIAL_REGEX_CHARS.matcher(str).replaceAll("\\\\$0");
}

Then you can use it like this, for example:

Pattern toSafePattern(String text)
{
    return Pattern.compile(".*" + escapeSpecialRegexChars(text) + ".*");
}

We needed to do that because, after escaping, we add some regex expressions. If not, you can simply use \Q and \E:

Pattern toSafePattern(String text)
{
    return Pattern.compile(".*\\Q" + text + "\\E.*")
}

So you didn't say you wanted the application to quit or exit abruptly, so as another option, perhaps just have the response loop end out elegantly. (I am assuming you have a while loop waiting for user instructions. This is some code from a project I just wrote today.

        Console.WriteLine("College File Processor");
        Console.WriteLine("*************************************");
        Console.WriteLine("(H)elp");
        Console.WriteLine("Process (W)orkouts");
        Console.WriteLine("Process (I)nterviews");
        Console.WriteLine("Process (P)ro Days");
        Console.WriteLine("(S)tart Processing");
        Console.WriteLine("E(x)it");
        Console.WriteLine("*************************************");

        string response = "";
        string videotype = "";
        bool starting = false;
        bool exiting = false;

        response = Console.ReadLine();

        while ( response != "" )
        {
            switch ( response  )
            {
                case "H":
                case "h":
                    DisplayHelp();
                    break;

                case "W":
                case "w":
                    Console.WriteLine("Video Type set to Workout");
                    videotype = "W";
                    break;

                case "I":
                case "i":
                    Console.WriteLine("Video Type set to Interview");
                    videotype = "I";
                    break;

                case "P":
                case "p":
                    Console.WriteLine("Video Type set to Pro Day");
                    videotype = "P";
                    break;

                case "S":
                case "s":
                    if ( videotype == "" )
                    {
                        Console.WriteLine("Please Select Video Type Before Starting");
                    }
                    else
                    {
                        Console.WriteLine("Starting...");
                        starting = true;
                    }
                    break;

                case "E":
                case "e":
                    Console.WriteLine("Good Bye!");
                    System.Threading.Thread.Sleep(100);
                    exiting = true;
                    break;
            }

            if ( starting || exiting)
            {
                break;
            }
            else
            {
                response = Console.ReadLine();
            }
        }

        if ( starting )
        {
            ProcessFiles();
        }

Window.postMessage()

This method safely enables cross-origin communication.

And if you have access to parent page code then any parent method can be called as well as any data can be passed directly from Iframe. Here is a small example:

Parent page:

if (window.addEventListener) {
    window.addEventListener("message", onMessage, false);        
} 
else if (window.attachEvent) {
    window.attachEvent("onmessage", onMessage, false);
}

function onMessage(event) {
    // Check sender origin to be trusted
    if (event.origin !== "http://example.com") return;

    var data = event.data;

    if (typeof(window[data.func]) == "function") {
        window[data.func].call(null, data.message);
    }
}

// Function to be called from iframe
function parentFunc(message) {
    alert(message);
}

Iframe code:

window.parent.postMessage({
    'func': 'parentFunc',
    'message': 'Message text from iframe.'
}, "*");
// Use target origin instead of *

UPDATES:

Security note:

Always provide a specific targetOrigin, NOT *, if you know where the other window's document should be located. Failing to provide a specific target discloses the data you send to any interested malicious site (comment by ZalemCitizen).

It's 2012, the post-PC era is here, and we still have to struggle with something as basic as this. This ought to be very simple.

Until such time as that dream is fulfilled, here's the best way to do this, cross-browser: use a combination of the input and onpropertychange events, like so:

var area = container.querySelector('textarea');
if (area.addEventListener) {
  area.addEventListener('input', function() {
    // event handling code for sane browsers
  }, false);
} else if (area.attachEvent) {
  area.attachEvent('onpropertychange', function() {
    // IE-specific event handling code
  });
}

The input event takes care of IE9+, FF, Chrome, Opera and Safari, and onpropertychange takes care of IE8 (it also works with IE6 and 7, but there are some bugs).

The advantage of using input and onpropertychange is that they don't fire unnecessarily (like when pressing the Ctrl or Shift keys); so if you wish to run a relatively expensive operation when the textarea contents change, this is the way to go.

Now IE, as always, does a half-assed job of supporting this: neither input nor onpropertychange fires in IE when characters are deleted from the textarea. So if you need to handle deletion of characters in IE, use keypress (as opposed to using keyup / keydown, because they fire only once even if the user presses and holds a key down).

Source: http://www.alistapart.com/articles/expanding-text-areas-made-elegant/

EDIT: It seems even the above solution is not perfect, as rightly pointed out in the comments: the presence of the addEventListener property on the textarea does not imply you're working with a sane browser; similarly the presence of the attachEvent property does not imply IE. If you want your code to be really air-tight, you should consider changing that. See Tim Down's comment for pointers.

window.location = url;

'url' is the web url you want to redirect.

This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....

To cover the identities listed:

IIS_IUSRS:

This is analogous to the old IIS6 IIS_WPG group. It's a built-in group with it's security configured such that any member of this group can act as an application pool identity.

IUSR:

This account is analogous to the old IUSR_<MACHINE_NAME> local account that was the default anonymous user for IIS5 and IIS6 websites (i.e. the one configured via the Directory Security tab of a site's properties).

For more information about IIS_IUSRS and IUSR see:

Understanding Built-In User and Group Accounts in IIS 7

DefaultAppPool:

If an application pool is configured to run using the Application Pool Identity feature then a "synthesised" account called IIS AppPool\<pool name> will be created on the fly to used as the pool identity. In this case there will be a synthesised account called IIS AppPool\DefaultAppPool created for the life time of the pool. If you delete the pool then this account will no longer exist. When applying permissions to files and folders these must be added using IIS AppPool\<pool name>. You also won't see these pool accounts in your computers User Manager. See the following for more information:

Application Pool Identities

ASP.NET v4.0: -

This will be the Application Pool Identity for the ASP.NET v4.0 Application Pool. See DefaultAppPool above.

NETWORK SERVICE: -

The NETWORK SERVICE account is a built-in identity introduced on Windows 2003. NETWORK SERVICE is a low privileged account under which you can run your application pools and websites. A website running in a Windows 2003 pool can still impersonate the site's anonymous account (IUSR_ or whatever you configured as the anonymous identity).

In ASP.NET prior to Windows 2008 you could have ASP.NET execute requests under the Application Pool account (usually NETWORK SERVICE). Alternatively you could configure ASP.NET to impersonate the site's anonymous account via the <identity impersonate="true" /> setting in web.config file locally (if that setting is locked then it would need to be done by an admin in the machine.config file).

Setting <identity impersonate="true"> is common in shared hosting environments where shared application pools are used (in conjunction with partial trust settings to prevent unwinding of the impersonated account).

In IIS7.x/ASP.NET impersonation control is now configured via the Authentication configuration feature of a site. So you can configure to run as the pool identity, IUSR or a specific custom anonymous account.

LOCAL SERVICE:

The LOCAL SERVICE account is a built-in account used by the service control manager. It has a minimum set of privileges on the local computer. It has a fairly limited scope of use:

LocalService Account

LOCAL SYSTEM:

You didn't ask about this one but I'm adding for completeness. This is a local built-in account. It has fairly extensive privileges and trust. You should never configure a website or application pool to run under this identity.

LocalSystem Account

In Practice:

In practice the preferred approach to securing a website (if the site gets its own application pool - which is the default for a new site in IIS7's MMC) is to run under Application Pool Identity. This means setting the site's Identity in its Application Pool's Advanced Settings to Application Pool Identity:

In the website you should then configure the Authentication feature:

Right click and edit the Anonymous Authentication entry:

Ensure that "Application pool identity" is selected:

When you come to apply file and folder permissions you grant the Application Pool identity whatever rights are required. For example if you are granting the application pool identity for the ASP.NET v4.0 pool permissions then you can either do this via Explorer:

Click the "Check Names" button:

Or you can do this using the ICACLS.EXE utility:

icacls c:\wwwroot\mysite /grant "IIS AppPool\ASP.NET v4.0":(CI)(OI)(M)

...or...if you site's application pool is called BobsCatPicBlogthen:

icacls c:\wwwroot\mysite /grant "IIS AppPool\BobsCatPicBlog":(CI)(OI)(M)

I hope this helps clear things up.

Update:

I just bumped into this excellent answer from 2009 which contains a bunch of useful information, well worth a read:

The difference between the 'Local System' account and the 'Network Service' account?

Simple solution by Underscore.js

For example: Get all links text who's parents have class someClass

_.pluck($('.someClass').find('a'), 'text');

Working fiddle

I'm surprised no one has proposed a solution using std::regex yet:

#include <string>
#include <algorithm>
#include <vector>
#include <regex>

void parse_csint( const std::string& str, std::vector<int>& result ) {

    typedef std::regex_iterator<std::string::const_iterator> re_iterator;
    typedef re_iterator::value_type re_iterated;

    std::regex re("(\\d+)");

    re_iterator rit( str.begin(), str.end(), re );
    re_iterator rend;

    std::transform( rit, rend, std::back_inserter(result), 
        []( const re_iterated& it ){ return std::stoi(it[1]); } );

}

This function inserts all integers at the back of the input vector. You can tweak the regular expression to include negative integers, or floating point numbers, etc.

To create a self signed certificate on Windows 7 with IIS 6...

1. Open IIS

2. Select your server (top level item or your computer's name)

3. Under the IIS section, open "Server Certificates"

4. Click "Create Self-Signed Certificate"

5. Name it "localhost" (or something like that that is not specific)

6. Click "OK"

You can then bind that certificate to your website...

1. Right click on your website and choose "Edit bindings..."

2. Click "Add"

   • Type: https
   • IP address: "All Unassigned"
   • Port: 443
   • SSL certificate: "localhost"

3. Click "OK"

4. Click "Close"

You can solve it very simple way just invoking the input. However, if you press Enter then the console will disapper again. Simply use this Console.ReadLine(); or Console.Read();

If you have access to JavaScript, you can create an element and read its computed style.

function defaultValueOfCssPropertyForElement(cssPropertyName, elementTagName, opt_pseudoElement) {
    var pseudoElement = opt_pseudoElement || null;
    var element = document.createElement(elementTagName);
    document.body.appendChild(element);
    var computedStyle = getComputedStyle(element, pseudoElement)[cssPropertyName];
    element.remove();
    return computedStyle;
}

// Usage:
defaultValueOfCssPropertyForElement('display', 'div'); // Output: 'block'
defaultValueOfCssPropertyForElement('content', 'div', ':after'); // Output: 'none'

Building on the previous answer by @BadPirate, I experimented a bit further and came up with some clarifications/corrections. I found that layoutSubviews: will be called on a view if and only if:

• Its own bounds (not frame) changed.
• The bounds of one of its direct subviews changed.
• A subview is added to the view or removed from the view.

Some relevant details:

• The bounds are considered changed only if the new value is different, including a different origin. Note specifically that is why layoutSubviews: is called whenever a UIScrollView scrolls, as it performs the scrolling by changing its bounds' origin.
• Changing the frame will only change the bounds if the size has changed, as this is the only thing propagated to the bounds property.
• A change in bounds of a view that is not yet in a view hierarchy will result in a call to layoutSubviews: when the view is eventually added to a view hierarchy.
• And just for completeness: these triggers do not directly call layoutSubviews, but rather call setNeedsLayout, which sets/raises a flag. Each iteration of the run loop, for all views in the view hierarchy, this flag is checked. For each view where the flag is found raised, layoutSubviews: is called on it and the flag is reset. Views higher up the hierarchy will be checked/called first.

You just did, as long as your table contains two columns and is called something like 'tblPeople'.

You can always write your own SQL wrappers. I actually prefer to do it that way, I HATE generated code, in any fashion.

Maybe create a DAL class, and have a method called GetPerson(int id), that queries the database for that person, and then creates your Person object from the result set.

With jQuery:

jQuery('#myDivID').css("background-color");

With prototype:

$('myDivID').getStyle('backgroundColor'); 

With pure JS:

document.getElementById("myDivID").style.backgroundColor

As of React v15, support for SVG in React is (close to?) 100% parity with current browser support for SVG (source). You just need to apply some syntax transformations to make it JSX compatible, like you already have to do for HTML (class ? className, style="color: purple" ? style={{color: 'purple'}}). For any namespaced (colon-separated) attribute, e.g. xlink:href, remove the : and capitalize the second part of the attribute, e.g. xlinkHref. Here’s an example of an svg with <defs>, <use>, and inline styles:

function SvgWithXlink (props) {
    return (
        <svg
            width="100%"
            height="100%"
            xmlns="http://www.w3.org/2000/svg"
            xmlnsXlink="http://www.w3.org/1999/xlink"
        >
            <style>
                { `.classA { fill:${props.fill} }` }
            </style>
            <defs>
                <g id="Port">
                    <circle style={{fill:'inherit'}} r="10"/>
                </g>
            </defs>

            <text y="15">black</text>
            <use x="70" y="10" xlinkHref="#Port" />
            <text y="35">{ props.fill }</text>
            <use x="70" y="30" xlinkHref="#Port" className="classA"/>
            <text y="55">blue</text>
            <use x="0" y="50" xlinkHref="#Port" style={{fill:'blue'}}/>
        </svg>
    );
}

Working codepen demo

For more details on specific support, check the docs’ list of supported SVG attributes. And here’s the (now closed) GitHub issue that tracked support for namespaced SVG attributes.

Previous answer

You can do a simple SVG embed without having to use dangerouslySetInnerHTML by just stripping the namespace attributes. For example, this works:

        render: function() {
            return (
                <svg viewBox="0 0 120 120">
                    <circle cx="60" cy="60" r="50"/>
                </svg>
            );
        }

At which point you can think about adding props like fill, or whatever else might be useful to configure.

you can convert a string to array with str_split and use foreach

$chars = str_split($str);
foreach($chars as $char){

It tells the browser to read the css file as UTF-8. This is handy if your CSS contains unicode characters and not only ASCII.

Using it in the meta tag is fine, but only for pages that include that meta tag.

Read about the rules for character set resolution of CSS files at the w3c spec for CSS 2.

When I do this, I get a very small square screen instead of a maxed screen. Yet, when I only use the FormWindowState.Maximized, it does give me a full screen. Why is that?

        public partial class Testscherm : Form
    {
            public Testscherm()

            {

                    this.WindowState = FormWindowState.Maximized;
                    this.MaximizeBox = false;
                    this.MinimizeBox = false;
                    this.MinimumSize = this.Size;
                    this.MaximumSize = this.Size;
                    this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedSingle;
                    InitializeComponent();

Plotly's R API might be useful for you. The graph below is here.

library(plotly)
#add username and key
p <- plotly(username="Username", key="API_KEY")
#generate data
x0 = rnorm(500)
x1 = rnorm(500)+1
#arrange your graph
data0 = list(x=x0,
         name = "Carrots",
         type='histogramx',
         opacity = 0.8)

data1 = list(x=x1,
         name = "Cukes",
         type='histogramx',
         opacity = 0.8)
#specify type as 'overlay'
layout <- list(barmode='overlay',
               plot_bgcolor = 'rgba(249,249,251,.85)')  
#format response, and use 'browseURL' to open graph tab in your browser.
response = p$plotly(data0, data1, kwargs=list(layout=layout))

url = response$url
filename = response$filename

browseURL(response$url)

Just wanted to add that GIF "transparency" is more like missing pixels. If you use GIF then you will see jagged edges where the background and the rest of the image meet. Using PNG, you can smoothly "composite" images together, which is what you really want. Plus PNG supports highly quality images.

Don't use "Paint". There are many high quality art applications for doing art work. I think even the cell phone apps (Pixlr is pretty good and free!) and web-based image editting apps are better. I use Gimp - free for all platforms.

While a JPEG can't be made transparent in and of itself, if your goal is to reduce the size of very large image areas for the web that need to contain transparent image areas, then there is a solution. It's a bit too complicated to post details, but Google it. Basically, you create your image with transparency and then split out the alpha channel (Gimp can do this easily) as a simple 8-bit greyscale PNG. Then you export the color data as a JPG. Now your web page uses a CANVAS tag to load the JPG as image data and applies the 8-bit greyscale PNG as the Canvas's alpha channel. The browser's Canvas does the work of making the image transparent. The JPEG stores the color info (better compressed than PNG) and the PNG is reduced to 8-bit alpha so its considerably smaller. I've saved a few hundred K per image using this technique. A few people have proposed file formats that embed PNG transparency info into a JPEG's extended information fields, but these proposal's don't have wide support as of yet.

from datetime import timedelta
try:
    next = (x.replace(day=1) + timedelta(days=31)).replace(day=x.day)
except ValueError:  # January 31 will return last day of February.
    next = (x + timedelta(days=31)).replace(day=1) - timedelta(days=1)

If you simply want the first day of the next month:

next = (x.replace(day=1) + timedelta(days=31)).replace(day=1)

Best way for me is:

1. create new branch, checkout to it
2. create or modify files, git add, git commit
3. back to master branch and do pull from remote (to get latest master changes)
4. merge newly created branch with master
5. remove newly created branch
6. push master to remote

Or you can push newly created branch on remote and merge there (if you do it this way, at the end you need to pull from remote master)

You are looking for a bit. It stores 1 or 0 (or NULL).

Alternatively, you could use the strings 'true' and 'false' in place of 1 or 0, like so-

declare @b1 bit = 'false'
print @b1                    --prints 0

declare @b2 bit = 'true'
print @b2                    --prints 1

Also, any non 0 value (either positive or negative) evaluates to (or converts to in some cases) a 1.

declare @i int = -42
print cast(@i as bit)    --will print 1, because @i is not 0

Note that SQL Server uses three valued logic (true, false, and NULL), since NULL is a possible value of the bit data type. Here are the relevant truth tables -

There are 3 ways to allow cross domain origin (excluding jsonp):

1) Set the header in the page directly using a templating language like PHP. Keep in mind there can be no HTML before your header or it will fail.

 <?php header("Access-Control-Allow-Origin: http://example.com"); ?>

2) Modify the server configuration file (apache.conf) and add this line. Note that "*" represents allow all. Some systems might also need the credential set. In general allow all access is a security risk and should be avoided:

Header set Access-Control-Allow-Origin "*"
Header set Access-Control-Allow-Credentials true

3) To allow multiple domains on Apache web servers add the following to your config file

<IfModule mod_headers.c>
    SetEnvIf Origin "http(s)?://(www\.)?(example.org|example.com)$" AccessControlAllowOrigin=$0$1
    Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
    Header set Access-Control-Allow-Credentials true
</IfModule>

4) For development use only hack your browser and allow unlimited CORS using the Chrome Allow-Control-Allow-Origin extension

5) Disable CORS in Chrome: Quit Chrome completely. Open a terminal and execute the following. Just be cautious you are disabling web security:

open -a Google\ Chrome --args --disable-web-security --user-data-dir

It may be a problem with the Google Play Services dependencies rather than an actual app version issue.

Sometimes, it is NOT the case that:

a) there is an existing version of the app installed, newer or not b) there is an existing version of the app installed on another user account on the device

So the error message is just bogus.

In my case, I had:

implementation 'com.google.android.gms:play-services-maps:16.0.0'
implementation 'com.google.android.gms:play-services-location:16.0.0'
implementation 'com.google.android.gms:play-services-gcm:16.0.0'

But when I tried

implementation 'com.google.android.gms:play-services-maps:17.0.0'
implementation 'com.google.android.gms:play-services-location:17.0.0'
implementation 'com.google.android.gms:play-services-gcm:17.0.0'

I got androidX related errors, as I had not yet upgraded to androidX and was not ready to do so. I found that using the latest 16.x.y versions work and I don't get the error message any more. Furthermore, I could wait till later when I am ready, to upgrade to androidX.

implementation 'com.google.android.gms:play-services-maps:16.+'
implementation 'com.google.android.gms:play-services-location:16.+'
implementation 'com.google.android.gms:play-services-gcm:16.+'

All you need is the following:

\makeatletter
\def\sec#1{\def\tempa{#1}\futurelet\next\sec@i}% Save first argument
\def\sec@i{\ifx\next\bgroup\expandafter\sec@ii\else\expandafter\sec@end\fi}%Check brace

Let's un-complicate Bootstrap!

Notice how the col-sm occupies the 100% width (in other terms breaks into new line) below 576px but col doesn't. You can notice the current width at the top center in gif.

Here comes the code:

<div class="container">
    <div class="row">
        <div class="col">col</div>
        <div class="col">col</div>
        <div class="col">col</div>
    </div>
    <div class="row">
        <div class="col-sm">col-sm</div>
        <div class="col-sm">col-sm</div>
        <div class="col-sm">col-sm</div>
    </div>
</div>

Bootstrap by default aligns all the columns(col) in a single row with equal width. In this case three col will occupy 100%/3 width each, whatever the screen size. You can notice that in gif.

Now what if we want to render only one column per line i.e give 100% width to each column but for smaller screens only? Now comes the col-xx classes!

I used col-sm because I wanted to break the columns into separate lines below 576px. These 4 col-xx classes are provided by Bootstrap for different display devices like mobiles, tablets, laptops, large monitors etc.

So,col-sm would break below 576px, col-md would break below 768px, col-lg would break below 992px and col-xl would break below 1200px

Note that there's no col-xs class in bootstrap 4.

This pretty much sums-up. You can go back to work.

But there's bit more to it. Now comes the col-* and col-xx-* for customizing width.

Remember in the above example I mentioned that col or col-xx takes the equal width in a row. So if we want to give more width to a specific col we can do this.

Bootstrap row is divided into 12 parts, so in above example there were 3 col so each one takes 12/3 = 4 part. You can consider these parts as a way to measure width.

We could also write that in format col-* i.e. col-4 like this :

<div class="row">
  <div class="col-4">col</div>
  <div class="col-4">col</div>
  <div class="col-4">col</div>
</div>

And it would've made no difference because by default bootstrap gives equal width to col (4 + 4 + 4 = 12).

But, what if we want to give 7 parts to 1st col, 3 parts to 2nd col and rest 2 parts (12-7-3 = 2) to 3rd col (7+3+2 so total is 12), we can simply do this:

<div class="row">
  <div class="col-7">col-7</div>
  <div class="col-3">col-3</div>
  <div class="col-2">col-2</div>
</div>

and you can customize the width of col-xx-* classes also.

<div class="row">
    <div class="col-sm-7">col-sm-7</div>
    <div class="col-sm-3">col-sm-3</div>
    <div class="col-sm-2">col-sm-2</div>
</div>

How does it look in the action?

What if sum of col is more than 12? Then the col will shift/adjust to below line. Yes, there can be any number of columns for a row!

<div class="row">
        <div class="col-12">col-12</div>
        <div class="col-9">col-9</div>
        <div class="col-6">col-6</div>
        <div class="col-6">col-6</div>
    </div>

What if we want 3 columns in a row for large screens but split these columns into 2 rows for small screens?

<div class="row">
    <div class="col-12 col-sm">col-12 col-sm TOP</div>
    <div class="col col-sm">col col-sm</div>
    <div class="col col-sm">col col-sm</div>
</div>

dplyr now has a function case_when that offers a vectorised if. The syntax is a little strange compared to mosaic:::derivedFactor as you cannot access variables in the standard dplyr way, and need to declare the mode of NA, but it is considerably faster than mosaic:::derivedFactor.

df %>%
mutate(g = case_when(a %in% c(2,5,7) | (a==1 & b==4) ~ 2L, 
                     a %in% c(0,1,3,4) | c == 4 ~ 3L, 
                     TRUE~as.integer(NA)))

EDIT: If you're using dplyr::case_when() from before version 0.7.0 of the package, then you need to precede variable names with '.$' (e.g. write .$a == 1 inside case_when).

Benchmark: For the benchmark (reusing functions from Arun 's post) and reducing sample size:

require(data.table) 
require(mosaic) 
require(dplyr)
require(microbenchmark)

set.seed(42) # To recreate the dataframe
DT <- setDT(lapply(1:6, function(x) sample(7, 10000, TRUE)))
setnames(DT, letters[1:6])
DF <- as.data.frame(DT)

DPLYR_case_when <- function(DF) {
  DF %>%
  mutate(g = case_when(a %in% c(2,5,7) | (a==1 & b==4) ~ 2L, 
                       a %in% c(0,1,3,4) | c==4 ~ 3L, 
                       TRUE~as.integer(NA)))
}

DT_fun <- function(DT) {
  DT[(a %in% c(0,1,3,4) | c == 4), g := 3L]
  DT[a %in% c(2,5,7) | (a==1 & b==4), g := 2L]
}

DPLYR_fun <- function(DF) {
  mutate(DF, g = ifelse(a %in% c(2,5,7) | (a==1 & b==4), 2L, 
                    ifelse(a %in% c(0,1,3,4) | c==4, 3L, NA_integer_)))
}

mosa_fun <- function(DF) {
  mutate(DF, g = derivedFactor(
    "2" = (a == 2 | a == 5 | a == 7 | (a == 1 & b == 4)),
    "3" = (a == 0 | a == 1 | a == 4 | a == 3 |  c == 4),
    .method = "first",
    .default = NA
  ))
}

perf_results <- microbenchmark(
  dt_fun <- DT_fun(copy(DT)),
  dplyr_ifelse <- DPLYR_fun(copy(DF)),
  dplyr_case_when <- DPLYR_case_when(copy(DF)),
  mosa <- mosa_fun(copy(DF)),
  times = 100L
)

This gives:

The $http legacy promise methods success and error have been deprecated. Use the standard then method instead. Have a look at the docs https://docs.angularjs.org/api/ng/service/$http

Now the right way to use is:

// Simple GET request example:
$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    // this callback will be called asynchronously
    // when the response is available
  }, function errorCallback(response) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
});

The response object has these properties:

• data – {string|Object} – The response body transformed with the transform functions.
• status – {number} – HTTP status code of the response.
• headers – {function([headerName])} – Header getter function.
• config – {Object} – The configuration object that was used to generate the request.
• statusText – {string} – HTTP status text of the response.

A response status code between 200 and 299 is considered a success status and will result in the success callback being called.

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

If you want to know the list of procedures you can run the following command -

show procedure status;

It will give you the list of procedures and their definers Then you can run the show create procedure <procedurename>;

You can use display: table-cell property as in the following code:

div {
     height: 100%;
     display: table-cell; 
     vertical-align: middle;
    }

You could even get, for example of a huge integer value, fib(4000000).

But still it does not (for now) supports an arbitrarily large float !!

If you need one big, large, float then check up on the decimal Module. There are examples of use on these foruns: OverflowError: (34, 'Result too large')

Another reference: http://docs.python.org/2/library/decimal.html

You can even using the gmpy module if you need a speed-up (which is likely to be of your interest): Handling big numbers in code

&something gives you the address of the std::vector object, not the address of the data it holds. &something.begin() gives you the address of the iterator returned by begin() (as the compiler warns, this is not technically allowed because something.begin() is an rvalue expression, so its address cannot be taken).

Assuming the container has at least one element in it, you need to get the address of the initial element of the container, which you can get via

• &something[0] or &something.front() (the address of the element at index 0), or

• &*something.begin() (the address of the element pointed to by the iterator returned by begin()).

In C++11, a new member function was added to std::vector: data(). This member function returns the address of the initial element in the container, just like &something.front(). The advantage of this member function is that it is okay to call it even if the container is empty.

For those who are still having hard time understanding this strtok() function, take a look at this pythontutor example, it is a great tool to visualize your C (or C++, Python ...) code.

In case the link got broken, paste in:

#include <stdio.h>
#include <string.h>

int main()
{
    char s[] = "Hello, my name is? Matthew! Hey.";
    char* p;
    for (char *p = strtok(s," ,?!."); p != NULL; p = strtok(NULL, " ,?!.")) {
      puts(p);
    }
    return 0;
}

Combine the SUBSTRING(), LEFT(), and CHARINDEX() functions.

SELECT LEFT(SUBSTRING(YOUR_FIELD,
                      CHARINDEX(';', YOUR_FIELD) + 1, 100),
                      CHARINDEX('[', YOUR_FIELD) - 1)
FROM YOUR_TABLE;

This assumes your field length will never exceed 100, but you can make it smarter to account for that if necessary by employing the LEN() function. I didn't bother since there's enough going on in there already, and I don't have an instance to test against, so I'm just eyeballing my parentheses, etc.

Here's a jquery plugin to do the same: http://s.technabled.com/jquery-foggle

There are several ways to do this:

$collection = Mage::getModel('...')
            ->getCollection()
            ->setPageSize(20)
            ->setCurPage(1);

Will get first 20 records.

Here is the alternative and maybe more readable way:

$collection = Mage::getModel('...')->getCollection();
$collection->getSelect()->limit(20);

This will call Zend Db limit. You can set offset as second parameter.

This is a template for a function decorator that does not require () if no parameters are to be given:

import functools


def decorator(x_or_func=None, *decorator_args, **decorator_kws):
    def _decorator(func):
        @functools.wraps(func)
        def wrapper(*args, **kws):
            if 'x_or_func' not in locals() \
                    or callable(x_or_func) \
                    or x_or_func is None:
                x = ...  # <-- default `x` value
            else:
                x = x_or_func
            return func(*args, **kws)

        return wrapper

    return _decorator(x_or_func) if callable(x_or_func) else _decorator

an example of this is given below:

def multiplying(factor_or_func=None):
    def _decorator(func):
        @functools.wraps(func)
        def wrapper(*args, **kwargs):
            if 'factor_or_func' not in locals() \
                    or callable(factor_or_func) \
                    or factor_or_func is None:
                factor = 1
            else:
                factor = factor_or_func
            return factor * func(*args, **kwargs)
        return wrapper
    return _decorator(factor_or_func) if callable(factor_or_func) else _decorator

Basically in java, continue is a statement. So continue statement is normally used with the loops to skip the current iteration.

For how and when it is used in java, refer link below. It has got explanation with example.

Hope it helps !!

Using a single Awk:

... | awk -F '[/:]' '{print $5}'

That is, using as field separator either / or :, the username is always in field 5.

To store it in a variable:

username=$(... | awk -F '[/:]' '{print $5}')

A more flexible implementation with sed that doesn't require username to be field 5:

... | sed -e s/:.*// -e s?.*/??

That is, delete everything from : and beyond, and then delete everything up until the last /. sed is probably faster too than awk, so this alternative is definitely better.

Upon trying all the answers above, I found that using "RequestsCookieJar" instead of the regular CookieJar for subsequent requests fixed my problem.

import requests
import json

# The Login URL
authUrl = 'https://whatever.com/login'

# The subsequent URL
testUrl = 'https://whatever.com/someEndpoint'

# Logout URL
testlogoutUrl = 'https://whatever.com/logout'

# Whatever you are posting
login_data =  {'formPosted':'1', 
               'login_email':'[email protected]', 
               'password':'pw'
               }

# The Authentication token or any other data that we will receive from the Authentication Request. 
token = ''

# Post the login Request
loginRequest = requests.post(authUrl, login_data)
print("{}".format(loginRequest.text))

# Save the request content to your variable. In this case I needed a field called token. 
token = str(json.loads(loginRequest.content)['token'])  # or ['access_token']
print("{}".format(token))

# Verify Successful login
print("{}".format(loginRequest.status_code))

# Create your Requests Cookie Jar for your subsequent requests and add the cookie
jar = requests.cookies.RequestsCookieJar()
jar.set('LWSSO_COOKIE_KEY', token)

# Execute your next request(s) with the Request Cookie Jar set
r = requests.get(testUrl, cookies=jar)
print("R.TEXT: {}".format(r.text))
print("R.STCD: {}".format(r.status_code))

# Execute your logout request(s) with the Request Cookie Jar set
r = requests.delete(testlogoutUrl, cookies=jar)
print("R.TEXT: {}".format(r.text))  # should show "Request Not Authorized"
print("R.STCD: {}".format(r.status_code))  # should show 401

Implementing Comparable means "I can compare myself with another object." This is typically useful when there's a single natural default comparison.

Implementing Comparator means "I can compare two other objects." This is typically useful when there are multiple ways of comparing two instances of a type - e.g. you could compare people by age, name etc.

You have an ID for each photo so my suggestion is you rename the photo. For example you rename it by the date

<?php
 $date = getdate();
 $name .= $date[hours];
 $name .= $date[minutes];
 $name .= $date[seconds];
 $name .= $date[year];
 $name .= $date[mon];
 $name .= $date[mday];
?>

note: don't forget the file extension of your file or you can generate random string for the photo, but I would not recommend that. I would also recommend you to check the file extension before you upload it to your directory.

<?php 
if ((($_FILES["photo"]["type"] == "image/jpeg")
            || ($_FILES["photo"]["type"] == "image/pjpg"))
            && ($_FILES["photo"]["size"] < 100000000))
            {
                move_uploaded_file($_FILES["photo"]["tmp_name"], $target.$name);

                if(mysql_query("your query"))
                {
                    //success handling
                }
                else 
                {
                    //failed handling
                }
            }
            else
            {
                //error handling
            }
?>

Hope this might help.

how to set center of the textboxes

If it is debian based.

aptitude show postgresql | grep State

But I guess you can just try to launch it with some flag like --version, that simply prints some info and exits.

Updated using "service postgres status". Try:

service postgres status
if [ "$?" -gt "0" ]; then
  echo "Not installed".
else
  echo "Intalled"
fi

For completeness, you can also use:

mystring = mystring.strip()  # the while loop will leave a trailing space, 
                  # so the trailing whitespace must be dealt with
                  # before or after the while loop
while '  ' in mystring:
    mystring = mystring.replace('  ', ' ')

which will work quickly on strings with relatively few spaces (faster than re in these situations).

In any scenario, Alex Martelli's split/join solution performs at least as quickly (usually significantly more so).

In your example, using the default values of timeit.Timer.repeat(), I get the following times:

str.replace: [1.4317800167340238, 1.4174888149192384, 1.4163512401715934]
re.sub:      [3.741931446594549,  3.8389395858970374, 3.973777672860706]
split/join:  [0.6530919432498195, 0.6252146571700905, 0.6346594329726258]

EDIT:

Just came across this post which provides a rather long comparison of the speeds of these methods.

The $ solution didn't work for me. However, By actually putting the tab character itself in the command did: sort -t'' -k2

sqlcmd works, System.Data.SqlClient not working - Server not found in Kerberos database. You should add RestrictedKrbHost SPN

https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-kile/445e4499-7e49-4f2a-8d82-aaf2d1ee3c47

5.1.2 SPNs with Serviceclass Equal to "RestrictedKrbHost"

Supporting the "RestrictedKrbHost" service class allows client applications to use Kerberos authentication when they do not have the identity of the service but have the server name. This does not provide client-to-service mutual authentication, but rather client-to-server computer authentication. Services of different privilege levels have the same session key and could decrypt each other's data if the underlying service does not ensure that data cannot be accessed by higher services.

JAVA_HOME and JRE_HOME are not used by Java itself. Some third-party programs (for example Apache Tomcat) expect one of these environment variables to be set to the installation directory of the JDK or JRE. If you are not using software that requires them, you do not need to set JAVA_HOME and JRE_HOME. PATH is an environment variable used by the operating system (Windows, Mac OS X, Linux) where it will look for native executable programs to run. You should add the bin subdirectory of your JDK installation directory to the PATH, so that you can use the javac and java commands and other JDK tools in a command prompt window.

       Start-Sleep 10
