With my pymongo version: 3.2.2 I had do the following

from bson.objectid import ObjectId
import pymongo

client = pymongo.MongoClient("localhost", 27017)
db = client.mydbname

db.ProductData.update_one({
  '_id': ObjectId(p['_id']['$oid'])
},{
  '$set': {
    'd.a': existing + 1
  }
}, upsert=False)

Building off some of the good answers already given, here is a purely Storyboard / Interface Builder-based solution that works in iOS 7.0+

Set the UITextView's User Defined Runtime Attributes for the following keys:

textContainer.lineFragmentPadding
textContainerInset

public static void main(String[] args) {
          Scanner input =new Scanner(System.in);
          System.out.print("enter how many:");
         int num =input.nextInt();
    int[] arr= new int [num];
    for(int b=0;b<arr.length;b++){
   System.out.print("enter no." + (b+1) +"=");
   arr[b]=input.nextInt();
    }

    for (int i=0; i<arr.length;i++) {
        for (int k=i;k<arr.length;k++) {

        if(arr[i] > arr[k]) {

        int temp=arr[k];
        arr[k]=arr[i];
        arr[i]=temp;
        }
            }

    }
    System.out.println("******************\n output\t accending order");


    for (int i : arr){
        System.out.println(i);
    }
}
}

The most easy to build, easy to use implementation I have found is made by theguardianproject team: https://github.com/guardianproject/android-ffmpeg

I use date.js. It handles this easily and takes care of all the leap-year nastiness.

I also had the same issue when I tried to install a Windows service, in my case I managed to resolved the issue by removing blank spaces in the folder path to the service .exe, below is the command worked for me in a command prompt

cd C:\Windows\Microsoft.NET\Framework\v4.0.30319

Press ENTER to change working directory

InstallUtil.exe C:\MyService\Release\ReminderService.exe

Press ENTER

I think is because you have try to persist an object that have a reference to another object that is not persist yet, and so it try in the "DB side" to put a reference to a row that not exists

it is not possible to pragmatically get the permission... but ill suggest you to put that line of code in try{} catch{} which make your app unfortunately stop... and in catch body make a dialog box which will navigate the user to small tutorial to enable the draw over other apps permission... then on yes button click put this code...

 Intent callSettingIntent= new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION);
            startActivity(callSettingIntent);

this intent is to directly open the list of draw over other apps to manage permissions and then from here it is one click to the draw over other apps Permissions ... i know this is Not the answer you're looking for... but Im doing this in my apps...

1.) Inside the database, head to the migrations table and delete the entry of the migration related to the table you want to drop.

Migration table image example

2.) Next, delete the table related to the migration you just deleted from instruction 1.

Delete table image example

3.) Finally, do the changes you want to the migration file of the table you deleted from instruction no. 2 then run php artisan migrate to migrate the table again.

I created a code to jump to the desired back stack index, it worked fine to my purpose.

ie. I have Fragment1, Fragment2 and Fragment3, I want to jump from Fragment3 to Fragment1

I created a method called onBackPressed in Fragment3 that jumps to Fragment1

Fragment3:

public void onBackPressed() {
    FragmentManager fragmentManager = getFragmentManager();
    fragmentManager.popBackStack(fragmentManager.getBackStackEntryAt(fragmentManager.getBackStackEntryCount()-2).getId(), FragmentManager.POP_BACK_STACK_INCLUSIVE);
}

In the activity, I need to know if my current fragment is the Fragment3, so I call the onBackPressed of my fragment instead calling super

FragmentActivity:

@Override
public void onBackPressed() {
    Fragment f = getSupportFragmentManager().findFragmentById(R.id.my_fragment_container);
    if (f instanceof Fragment3)
    {
        ((Fragment3)f).onBackPressed();
    } else {
        super.onBackPressed();
    }
}

Your data.frame mat is rectangular (n_rows!= n_cols).

Therefore, you cannot make a data.frame out of the column- and rownames, because each column in a data.frame must be the same length.

Maybe this suffices your needs:

require(reshape2)
mat$id <- rownames(mat) 
melt(mat)

Use $key => $val to get the keys:

<?php

$arr = array(
    1 => "Value1",
    2 => "Value2",
    10 => "Value10",
);

foreach ($arr as $key => $val) {
   print "$key\n";
}

?>

It's not firing because the value hasn't "changed". It's the same value. Unfortunately, you can't achieve the desired behaviour using the change event.

You can handle the blur event and do whatever processing you need when the user leaves the select box. That way you can run the code you need even if the user selects the same value.

I'm using this one-liner in linux to convert files (usually H265) into something I can play on Kodi without issues:

for f in *.mkv; do ffmpeg -i "$f" -c:v libx264 -crf 28 -c:a aac -b:a 128k output.mkv; mv -f output.mkv "$f"; done

This converts to a temporary file and then replaces the original so the names remain the same after conversion.

WebClient is a higher-level abstraction built on top of HttpWebRequest to simplify the most common tasks. For instance, if you want to get the content out of an HttpWebResponse, you have to read from the response stream:

var http = (HttpWebRequest)WebRequest.Create("http://example.com");
var response = http.GetResponse();

var stream = response.GetResponseStream();
var sr = new StreamReader(stream);
var content = sr.ReadToEnd();

With WebClient, you just do DownloadString:

var client = new WebClient();
var content = client.DownloadString("http://example.com");

Note: I left out the using statements from both examples for brevity. You should definitely take care to dispose your web request objects properly.

In general, WebClient is good for quick and dirty simple requests and HttpWebRequest is good for when you need more control over the entire request.

As was told at MySQL Using a string column with date text as a date field, you can do

SELECT  STR_TO_DATE(yourdatefield, '%m/%d/%Y')
FROM    yourtable

You can also handle these date strings in WHERE clauses. For example

SELECT whatever
  FROM yourtable
 WHERE STR_TO_DATE(yourdatefield, '%m/%d/%Y') > CURDATE() - INTERVAL 7 DAY

You can handle all kinds of date/time layouts this way. Please refer to the format specifiers for the DATE_FORMAT() function to see what you can put into the second parameter of STR_TO_DATE().

You can use this piece of code:

  <iframe src="http://example.com" frameborder="0" style="overflow:hidden;overflow-x:hidden;overflow-y:hidden;height:100%;width:100%;position:absolute;top:0%;left:0px;right:0px;bottom:0px" height="100%" width="100%"></iframe>

To save file into directory

  public static Uri saveImageToInternalStorage(Context mContext, Bitmap bitmap){

    String mTimeStamp = new SimpleDateFormat("ddMMyyyy_HHmm").format(new Date());

    String mImageName = "snap_"+mTimeStamp+".jpg";

    ContextWrapper wrapper = new ContextWrapper(mContext);

    File file = wrapper.getDir("Images",MODE_PRIVATE);

    file = new File(file, "snap_"+ mImageName+".jpg");

    try{

        OutputStream stream = null;

        stream = new FileOutputStream(file);

        bitmap.compress(Bitmap.CompressFormat.JPEG,100,stream);

        stream.flush();

        stream.close();

    }catch (IOException e) 
    {
        e.printStackTrace();
    }

    Uri mImageUri = Uri.parse(file.getAbsolutePath());

    return mImageUri;
}

required permission

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

2019 answer, as most of the above is depracated.

tf undo /workspace:"hostname;username" "$/path/*" /s:https://yourhostname/tfs in an elevated command prompt, from a path such as C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE>

echo '<script language="javascript">';
echo 'alert("message successfully sent")';
echo '</script>';

The answer is: you can't only through sms, i have tried that approach before.

You could fetch the base station IDs, but this won't help you a lot without the location of the base station itself and this informations are really hard to retrieve from the providers.

I have looked through the 3 apps you have listed in your question:

1. The App uses WiFi and GPRS location service, quite the same approach as Google uses on the phone. phonesavvy maybe has a base station location database or uses a database retrieved e.g. from OpenStreetMap or some similar crowd-based project.
2. The app analyzes just the number for country code and city code. No location there.
3. Dito.

One major difference that is important to know is that ActiveX controls show up as objects that you can use in your code- try inserting an ActiveX control into a worksheet, bring up the VBA editor (ALT + F11) and you will be able to access the control programatically. You can't do this with form controls (macros must instead be explicitly assigned to each control), but form controls are a little easier to use. If you are just doing something simple, it doesn't matter which you use but for more advanced scripts ActiveX has better possibilities.

ActiveX is also more customizable.

The solution is very simple if we consider the type of the constant value, which should be "unsigned int" instead of "int".

Instead of:

setval(0)

Use:

setval(0u)

The suffix "u" tell the compiler this is a unsigned integer. Then, no conversion would be needed, and the call will be unambiguous.

I had this same problem, do this

if [ 'xyz' = 'abc' ]; then
  echo "match"
fi

Notice the whitespace. It is important that you use a whitespace in this case after and before the = sign.

Check out "Other Comparison Operators".

Just:

/path/to/file/my_script.sh

In addition to what has been said, prior to returning your error code, fire off an assert or similar diagnostic when an error is returned, as it will make tracing a lot easier. The way I do this is to have a customised assert that still gets compiled in at release but only gets fired when the software is in diagnostics mode, with an option to silently report to a log file or pause on screen.

I personally return error codes as negative integers with no_error as zero , but it does leave you with the possible following bug

if (MyFunc())
 DoSomething();

An alternative is have a failure always returned as zero, and use a LastError() function to provide details of the actual error.

I found this way to expand a DNS RR hostname that expands into a list of IPs, into the list of member hostnames:

#!/usr/bin/python

def expand_dnsname(dnsname):
    from socket import getaddrinfo
    from dns import reversename, resolver
    namelist = [ ]
    # expand hostname into dict of ip addresses
    iplist = dict()
    for answer in getaddrinfo(dnsname, 80):
        ipa = str(answer[4][0])
        iplist[ipa] = 0
    # run through the list of IP addresses to get hostnames
    for ipaddr in sorted(iplist):
        rev_name = reversename.from_address(ipaddr)
        # run through all the hostnames returned, ignoring the dnsname
        for answer in resolver.query(rev_name, "PTR"):
            name = str(answer)
            if name != dnsname:
                # add it to the list of answers
                namelist.append(name)
                break
    # if no other choice, return the dnsname
    if len(namelist) == 0:
        namelist.append(dnsname)
    # return the sorted namelist
    namelist = sorted(namelist)
    return namelist

namelist = expand_dnsname('google.com.')
for name in namelist:
    print name

Which, when I run it, lists a few 1e100.net hostnames:

public static void printMatrix(double[][] matrix) {
    for (double[] row : matrix) {
        for (double element : row) {
            System.out.printf("%5.1f", element);
        }
        System.out.println();
    }
}

Function Call

printMatrix(new double[][]{2,0,0},{0,2,0},{0,0,3}});

Output:

  2.0  0.0  0.0
  0.0  2.0  0.0
  0.0  0.0  3.0

In console:

I agree with the points dnmckee mentions, plus:

• Statically linked applications might be easier to deploy, since there are fewer or no additional file dependencies (.dll / .so) that might cause problems when they're missing or installed in the wrong place.

why would you override the toString() method?

(Update: August 2011)

As geofflane mentions in his answer, Java 7 now support named groups.
tchrist points out in the comment that the support is limited.
He details the limitations in his great answer "Java Regex Helper"

Java 7 regex named group support was presented back in September 2010 in Oracle's blog.

In the official release of Java 7, the constructs to support the named capturing group are:

• (?<name>capturing text) to define a named group "name"
• \k<name> to backreference a named group "name"
• ${name} to reference to captured group in Matcher's replacement string
• Matcher.group(String name) to return the captured input subsequence by the given "named group".

Other alternatives for pre-Java 7 were:

• Google named-regex (see John Hardy's answer)
  Gábor Lipták mentions (November 2012) that this project might not be active (with several outstanding bugs), and its GitHub fork could be considered instead.
• jregex (See Brian Clozel's answer)

(Original answer: Jan 2009, with the next two links now broken)

You can not refer to named group, unless you code your own version of Regex...

That is precisely what Gorbush2 did in this thread.

Regex2

(limited implementation, as pointed out again by tchrist, as it looks only for ASCII identifiers. tchrist details the limitation as:

only being able to have one named group per same name (which you don’t always have control over!) and not being able to use them for in-regex recursion.

Note: You can find true regex recursion examples in Perl and PCRE regexes, as mentioned in Regexp Power, PCRE specs and Matching Strings with Balanced Parentheses slide)

Example:

String:

"TEST 123"

RegExp:

"(?<login>\\w+) (?<id>\\d+)"

Access

matcher.group(1) ==> TEST
matcher.group("login") ==> TEST
matcher.name(1) ==> login

Replace

matcher.replaceAll("aaaaa_$1_sssss_$2____") ==> aaaaa_TEST_sssss_123____
matcher.replaceAll("aaaaa_${login}_sssss_${id}____") ==> aaaaa_TEST_sssss_123____ 

(extract from the implementation)

<span>You have {{products|length}} products</span>

You can also use this syntax in expressions like

{% if products|length > 1 %}

jinja2's builtin filters are documented here; and specifically, as you've already found, length (and its synonym count) is documented to:

Return the number of items of a sequence or mapping.

So, again as you've found, {{products|count}} (or equivalently {{products|length}}) in your template will give the "number of products" ("length of list")

with open('filename.csv') as f:
   print(f)

after executing this code you will find encoding of 'filename.csv' then execute code as following

data=pd.read_csv('filename.csv', encoding="encoding as you found earlier"

there you go

You can do it the old fashioned way... with an SQL statement that looks something like this

ALTER TABLE table_name
    ADD CONSTRAINT fk_foreign_key_name
    FOREIGN KEY (foreign_key_name)
    REFERENCES target_table(target_key_name);

This assumes the keys already exist in the relevant table

Try mpstat from the sysstat package

> sudo apt-get install sysstat

Then some cutor grepto parse the info you need:

mpstat | grep -A 5 "%idle" | tail -n 1 | awk -F " " '{print 100 -  $ 12}'a

[Updated to adapt to modern pandas, which has isnull as a method of DataFrames..]

You can use isnull and any to build a boolean Series and use that to index into your frame:

>>> df = pd.DataFrame([range(3), [0, np.NaN, 0], [0, 0, np.NaN], range(3), range(3)])
>>> df.isnull()
       0      1      2
0  False  False  False
1  False   True  False
2  False  False   True
3  False  False  False
4  False  False  False
>>> df.isnull().any(axis=1)
0    False
1     True
2     True
3    False
4    False
dtype: bool
>>> df[df.isnull().any(axis=1)]
   0   1   2
1  0 NaN   0
2  0   0 NaN

[For older pandas:]

You could use the function isnull instead of the method:

In [56]: df = pd.DataFrame([range(3), [0, np.NaN, 0], [0, 0, np.NaN], range(3), range(3)])

In [57]: df
Out[57]: 
   0   1   2
0  0   1   2
1  0 NaN   0
2  0   0 NaN
3  0   1   2
4  0   1   2

In [58]: pd.isnull(df)
Out[58]: 
       0      1      2
0  False  False  False
1  False   True  False
2  False  False   True
3  False  False  False
4  False  False  False

In [59]: pd.isnull(df).any(axis=1)
Out[59]: 
0    False
1     True
2     True
3    False
4    False

leading to the rather compact:

In [60]: df[pd.isnull(df).any(axis=1)]
Out[60]: 
   0   1   2
1  0 NaN   0
2  0   0 NaN

You can create a putty session, and auto load the script on the server, when starting the session:

putty -load "sessionName" 

At remote command, point to the remote script.

Change it to the following:

$ci = get_instance();
$ci->load->library('email');
$config['protocol'] = "smtp";
$config['smtp_host'] = "ssl://smtp.gmail.com";
$config['smtp_port'] = "465";
$config['smtp_user'] = "[email protected]"; 
$config['smtp_pass'] = "yourpassword";
$config['charset'] = "utf-8";
$config['mailtype'] = "html";
$config['newline'] = "\r\n";

$ci->email->initialize($config);

$ci->email->from('[email protected]', 'Blabla');
$list = array('[email protected]');
$ci->email->to($list);
$this->email->reply_to('[email protected]', 'Explendid Videos');
$ci->email->subject('This is an email test');
$ci->email->message('It is working. Great!');
$ci->email->send();

You can add a column to your data using various techniques. The quotes below come from the "Details" section of the relevant help text, [[.data.frame.

Data frames can be indexed in several modes. When [ and [[ are used with a single vector index (x[i] or x[[i]]), they index the data frame as if it were a list.

my.dataframe["new.col"] <- a.vector
my.dataframe[["new.col"]] <- a.vector

The data.frame method for $, treats x as a list

my.dataframe$new.col <- a.vector

When [ and [[ are used with two indices (x[i, j] and x[[i, j]]) they act like indexing a matrix

my.dataframe[ , "new.col"] <- a.vector

Since the method for data.frame assumes that if you don't specify if you're working with columns or rows, it will assume you mean columns.

For your example, this should work:

# make some fake data
your.df <- data.frame(no = c(1:4, 1:7, 1:5), h_freq = runif(16), h_freqsq = runif(16))

# find where one appears and 
from <- which(your.df$no == 1)
to <- c((from-1)[-1], nrow(your.df)) # up to which point the sequence runs

# generate a sequence (len) and based on its length, repeat a consecutive number len times
get.seq <- mapply(from, to, 1:length(from), FUN = function(x, y, z) {
            len <- length(seq(from = x[1], to = y[1]))
            return(rep(z, times = len))
         })

# when we unlist, we get a vector
your.df$group <- unlist(get.seq)
# and append it to your original data.frame. since this is
# designating a group, it makes sense to make it a factor
your.df$group <- as.factor(your.df$group)

The datasource is by default .\SQLEXPRESS (its the instance where databases are placed by default) or if u changed the name of the instance during installation of sql server so i advise you to do this :

connectionString="Data Source=.\\yourInstance(defaulT Data source is SQLEXPRESS);
       Initial Catalog=databaseName;
       User ID=theuser if u use it;
       Password=thepassword if u use it;
       integrated security=true(if u don t use user and pass; else change it false)"

Without to knowing your instance, I could help with this one. Hope it helped

What about this regex: \\[^\\]+$

$date = strtotime(date("Y-m-d", strtotime($date)) . " +1 day");

Or, simplier:

date("Y-m-d H:i:s", time()+((60*60)*24));

I faced the same problem once. In my case it was because of overridden equals method. One values was coming null.

just call the finish() in the method you would like to end the activity in, for example when you use the onCreate() method, in the end of the method, just add finish() and you will see the activity ends as soon as it is created!

To hide your status bar in iOS7:

Open Your plist-file, then add a add a row called "View controller-based status bar appearance" and set its value to NO.

I would store the timespan.TotalSeconds in a float and then retrieve it using Timespan.FromSeconds(totalSeconds).

Depending on the resolution you need you could use TotalMilliseconds, TotalMinutes, TotalDays.

You could also adjust the precision of your float in the database.

It's not an exact value... but the nice thing about this is that it's easy to read and calculate in simple queries.

Here is something I think will work for what you want, using a decorator.

class LogWrappedFunction(object):
    def __init__(self, function):
        self.function = function

    def logAndCall(self, *arguments, **namedArguments):
        print "Calling %s with arguments %s and named arguments %s" %\
                      (self.function.func_name, arguments, namedArguments)
        self.function.__call__(*arguments, **namedArguments)

def logwrap(function):
    return LogWrappedFunction(function).logAndCall

@logwrap
def doSomething(spam, eggs, foo, bar):
    print "Doing something totally awesome with %s and %s." % (spam, eggs)


doSomething("beans","rice", foo="wiggity", bar="wack")

Run it, it will yield the following output:

C:\scripts>python decoratorExample.py
Calling doSomething with arguments ('beans', 'rice') and named arguments {'foo':
 'wiggity', 'bar': 'wack'}
Doing something totally awesome with beans and rice.

You can use Apache Commons CollectionUtils:

if(CollectionUtils.containsAny(list1,list2)) {  
    // do whatever you want
} else { 
    // do other thing 
}  

This assumes that you have properly overloaded the equals functionality for your custom objects.

You can set the row height by code

dataGridView.RowTemplate.Height = 35;

or by property panel

You're using the declarative style of specifying your pipeline, so you must not use try/catch blocks (which are for Scripted Pipelines), but the post section. See: https://jenkins.io/doc/book/pipeline/syntax/#post-conditions

For Windows, you can use winsound. It's built in

import winsound

winsound.PlaySound('sound.wav', winsound.SND_FILENAME)

You should be able to use ossaudiodev for linux:

from wave import open as waveOpen
from ossaudiodev import open as ossOpen
s = waveOpen('tada.wav','rb')
(nc,sw,fr,nf,comptype, compname) = s.getparams( )
dsp = ossOpen('/dev/dsp','w')
try:
  from ossaudiodev import AFMT_S16_NE
except ImportError:
  from sys import byteorder
  if byteorder == "little":
    AFMT_S16_NE = ossaudiodev.AFMT_S16_LE
  else:
    AFMT_S16_NE = ossaudiodev.AFMT_S16_BE
dsp.setparameters(AFMT_S16_NE, nc, fr)
data = s.readframes(nf)
s.close()
dsp.write(data)
dsp.close()

Textbox.Focus() "Tries" to set focus on the textbox element. In case of the element visibility is hidden for example, Focus() will not work. So make sure that your element is visible before calling Focus().

Like the following. It will make the user database owner.

EXEC sp_addrolemember N'db_owner', N'USerNAme'

Also, if you had multiple event handlers attached to the same selector executing the same function, you could use

$('table.planning_grid').on('mouseenter mouseleave', function() {
    //JS Code
});

To complete Sunit's answer, you can use a selector, not to the text string but to the textColorHint. You must add this attribute on your editText:

android:textColorHint="@color/text_hint_selector"

And your text_hint_selector should be:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:color="@android:color/transparent" />
    <item android:color="@color/hint_color" />
</selector>

Note: This question is related to the jQuery form plugin. If you are searching for a pure jQuery solution, start here. There is no overall jQuery solution for all browser. So you have to use a plugin. I am using dropzone.js, which have an easy fallback for older browsers. Which plugin you prefer depends on your needs. There are a lot of good comparing post out there.

From the examples:

jQuery:

$(function() {

    var bar = $('.bar');
    var percent = $('.percent');
    var status = $('#status');

    $('form').ajaxForm({
        beforeSend: function() {
            status.empty();
            var percentVal = '0%';
            bar.width(percentVal);
            percent.html(percentVal);
        },
        uploadProgress: function(event, position, total, percentComplete) {
            var percentVal = percentComplete + '%';
            bar.width(percentVal);
            percent.html(percentVal);
        },
        complete: function(xhr) {
            status.html(xhr.responseText);
        }
    });
}); 

html:

<form action="file-echo2.php" method="post" enctype="multipart/form-data">
    <input type="file" name="myfile"><br>
    <input type="submit" value="Upload File to Server">
</form>

<div class="progress">
    <div class="bar"></div >
    <div class="percent">0%</div >
</div>

<div id="status"></div>

you have to style the progressbar with css...

I'm not sure whether ZohoGorganzola's solution is correct; however, you may want to try getting at the element directly rather than trying to invoke a method on the jQuery collection, so instead of

$("#videoContainer").pause();

try

$("#videoContainer")[0].pause();

class MyApp2 extends StatelessWidget {

  @override
  Widget build(BuildContext context) { 
    return MaterialApp( 
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        appBarTheme: AppBarTheme(
          elevation: 0,
          color: Colors.blueAccent,
        )
      ),
      title: 'Welcome to flutter ',
      home: HomePage()
    );
  }
}

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {

  int number = 0;
  void _increment(){
   setState(() {
      number ++;
   });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        backgroundColor: Colors.blueAccent,
        appBar: AppBar(
          title: Text('MyApp2'), 
          leading: Icon(Icons.menu),
          // backgroundColor: Colors.blueAccent,

          ),
        body: Container(
          decoration: BoxDecoration(
            borderRadius: BorderRadius.only(
              topLeft: Radius.circular(200.0),
              topRight: Radius.circular(200)
            ), 
            color: Colors.white,
          ),
        )
      );
  }
}

Ok, the way I see it you have 3 options.

1: If you simply wish to check whether the number is an integer, and don't care about converting it, but simply wish to keep it as a string and don't care about potential overflows, checking whether it matches a regex for an integer would be ideal here.

2: You can use boost::lexical_cast and then catch a potential boost::bad_lexical_cast exception to see if the conversion failed. This would work well if you can use boost and if failing the conversion is an exceptional condition.

3: Roll your own function similar to lexical_cast that checks the conversion and returns true/false depending on whether it's successful or not. This would work in case 1 & 2 doesn't fit your requirements.

Encoding.ASCII.GetString(buf);

The timeout command is available from Windows Vista onwards:

c:\> timeout /?

TIMEOUT [/T] timeout [/NOBREAK]

Description:
    This utility accepts a timeout parameter to wait for the specified
    time period (in seconds) or until any key is pressed. It also
    accepts a parameter to ignore the key press.

Parameter List:
    /T        timeout       Specifies the number of seconds to wait.
                            Valid range is -1 to 99999 seconds.

    /NOBREAK                Ignore key presses and wait specified time.

    /?                      Displays this help message.

NOTE: A timeout value of -1 means to wait indefinitely for a key press.

Examples:
    TIMEOUT /?
    TIMEOUT /T 10
    TIMEOUT /T 300 /NOBREAK
    TIMEOUT /T -1

Note: It does not work with input redirection - trivial example:

C:\>echo 1 | timeout /t 1 /nobreak
ERROR: Input redirection is not supported, exiting the process immediately.

I encountered this error when I use Mysql Cluster, I do not know this question is from a cluster usage or not. As the error is exactly the same, so give my solution here. Getting this error because the data nodes suddenly crash. But when the nodes crash, you can still get the correct result using cmd:

ndb_mgm -e 'ALL REPORT MEMORYUSAGE'

And the mysqld also works correctly.So at first, I can not understand what is wrong. And about 5 mins later, ndb_mgm result shows no data node working. Then I realize the problem. So, try to restart all the data nodes, then the mysql server is back and everything is OK.

But one thing is weird to me, after I lost mysql server for some queries, when I use cmd like show tables, I can still get the return info like 33 rows in set (5.57 sec), but no table info is displayed.

If you are using Python 2, the following will be the solution:

import io
for line in io.open("u.item", encoding="ISO-8859-1"):
    # Do something

Because the encoding parameter doesn't work with open(), you will be getting the following error:

TypeError: 'encoding' is an invalid keyword argument for this function

There is no such functionality in jQuery. Use JSON.stringify or alternatively any jQuery plugin with similar functionality (e.g jquery-json).

I had the same problem before and i fixed it by creating the same table in a new sheet and deleting all the name ranges associated to the table, i believe whene you're using listobjects you're not alowed to have name ranges contained within your table hope that helps thanks

Here goes what O'reilly Enterprise JavaBeans, 3.0 says

JDBC has special types for these very large objects. The java.sql.Blob type represents binary data, and java.sql.Clob represents character data.

Here goes PostgreSQLDialect source code

public PostgreSQLDialect() {
    super();
    ...
    registerColumnType(Types.VARBINARY, "bytea");
    /**
      * Notice it maps java.sql.Types.BLOB as oid
      */
    registerColumnType(Types.BLOB, "oid");
}

So what you can do

Override PostgreSQLDialect as follows

public class CustomPostgreSQLDialect extends PostgreSQLDialect {

    public CustomPostgreSQLDialect() {
        super();

        registerColumnType(Types.BLOB, "bytea");
    }
}

Now just define your custom dialect

<property name="hibernate.dialect" value="br.com.ar.dialect.CustomPostgreSQLDialect"/>

And use your portable JPA @Lob annotation

@Lob
public byte[] getValueBuffer() {

UPDATE

Here has been extracted here

I have an application running in hibernate 3.3.2 and the applications works fine, with all blob fields using oid (byte[] in java)

...

Migrating to hibernate 3.5 all blob fields not work anymore, and the server log shows: ERROR org.hibernate.util.JDBCExceptionReporter - ERROR: column is of type oid but expression is of type bytea

which can be explained here

This generaly is not bug in PG JDBC, but change of default implementation of Hibernate in 3.5 version. In my situation setting compatible property on connection did not helped.

...

Much more this what I saw in 3.5 - beta 2, and i do not know if this was fixed is Hibernate - without @Type annotation - will auto-create column of type oid, but will try to read this as bytea

Interesting is because when he maps Types.BOLB as bytea (See CustomPostgreSQLDialect) He get

Could not execute JDBC batch update

You can start containers by using:

$ docker-compose up -d client

This will run containers in the background and output will be avaiable from

$ docker-compose logs

and it will consist of all your started containers

Use the following methods on HttpServletRequest object

java.lang.String getRequestURI() -Returns the part of this request's URL from the protocol name up to the query string in the first line of the HTTP request.

java.lang.StringBuffer getRequestURL() -Reconstructs the URL the client used to make the request.

java.lang.String getQueryString() -Returns the query string that is contained in the request URL after the path.

You can download manually by parsing the XMLs that you see in Android SDK Manager log.
Currently the XMLs are addon_list and repository. These xmls can change over a course of time.

It has the location of the SDKs, you can browse to the link and download directly via browser. These files has to be placed under proper folder, example the files of google APIs has to be placed under add-ons, if you don't know where the files has to go.

Here is something to help you.
The blogpost from my blog to Install Android SDKs offline --> Offline Installation of Android SDK's

I might argue that the answer here generally is "don't". Unless you absolutely need all the data at once, consider using a Stream-based API (or some variant of reader / iterator). That is especially important when you have multiple parallel operations (as suggested by the question) to minimise system load and maximise throughput.

For example, if you are streaming data to a caller:

Stream dest = ...
using(Stream source = File.OpenRead(path)) {
    byte[] buffer = new byte[2048];
    int bytesRead;
    while((bytesRead = source.Read(buffer, 0, buffer.Length)) > 0) {
        dest.Write(buffer, 0, bytesRead);
    }
}

We copy the JRE's truststore and add our custom certificates to that truststore, then tell the application to use the custom truststore with a system property. This way we leave the default JRE truststore alone.

The downside is that when you update the JRE you don't get its new truststore automatically merged with your custom one.

You could maybe handle this scenario by having an installer or startup routine that verifies the truststore/jdk and checks for a mismatch or automatically updates the truststore. I don't know what happens if you update the truststore while the application is running.

This solution isn't 100% elegant or foolproof but it's simple, works, and requires no code.

The question on itself is very much invalid. Forcing (by doing enable_seqscan=off for example) is very bad idea. It might be useful to check if it will be faster, but production code should never use such tricks.

Instead - do explain analyze of your query, read it, and find out why PostgreSQL chooses bad (in your opinion) plan.

There are tools on the web that help with reading explain analyze output - one of them is explain.depesz.com - written by me.

Another option is to join #postgresql channel on freenode irc network, and talking to guys there to help you out - as optimizing query is not a matter of "ask a question, get answer be happy". it's more like a conversation, with many things to check, many things to be learned.

ONE COLOR CASE - CSS only

Just to register my experience, where I wanted to set only the color of the selected option to a specific one.

I first tried to set by css only the color of the selected option with no success.

Then, after trying some combinations, this has worked for me with SCSS:

select {
      color: white; // color of the selected option

      option {
        color: black; // color of all the other options
      }
 }

Take a look at a working example with only CSS:

select {_x000D_
  color: yellow; // color of the selected option_x000D_
 }_x000D_
_x000D_
select option {_x000D_
  color: black; // color of all the other options_x000D_
}

<select id="mySelect">_x000D_
    <option value="apple" >Apple</option>_x000D_
    <option value="banana" >Banana</option>_x000D_
    <option value="grape" >Grape</option>_x000D_
</select>

For different colors, depending on the selected option, you'll have to deal with js.

Since each test is executed independently, with a fresh instance of the object, there's not much point to the Test object having any internal state except that shared between setUp() and an individual test and tearDown(). This is one reason (in addition to the reasons others gave) that it's good to use the setUp() method.

Note: It's a bad idea for a JUnit test object to maintain static state! If you make use of static variable in your tests for anything other than tracking or diagnostic purposes, you are invalidating part of the purpose of JUnit, which is that the tests can (an may) be run in any order, each test running with a fresh, clean state.

The advantages to using setUp() is that you don't have to cut-and-paste initialization code in every test method and that you don't have test setup code in the constructor. In your case, there is little difference. Just creating an empty list can be done safely as you show it or in the constructor as it's a trivial initialization. However, as you and others have pointed out, anything that can possibly throw an Exception should be done in setUp() so you get the diagnostic stack dump if it fails.

In your case, where you are just creating an empty list, I would do the same way you are suggesting: Assign the new list at the point of declaration. Especially because this way you have the option of marking it final if this makes sense for your test class.

Using System.Text.Json set JsonSerializerOptions.WriteIndented = true:

JsonSerializerOptions options = new JsonSerializerOptions { WriteIndented = true };
string json = JsonSerializer.Serialize<Type>(object, options);

You can use the "-r" option to set the sender address:

mail -r [email protected] -s ...

In case you also want to include your real name in the from-field, you can use the following format

mail -r "[email protected] (My Name)" -s "My Subject" ...

There is solution for you :)

You must run your script after window loaded

if you use jQuery, you can use simple way:

<div id="fb-root"></div>
<script>
    window.fbAsyncInit = function() {
        FB.init({
            appId      : 'your-app-id',
            xfbml      : true,
            status     : true,
            version    : 'v2.5'
        });
    };

    (function(d, s, id){
        var js, fjs = d.getElementsByTagName(s)[0];
        if (d.getElementById(id)) {return;}
        js = d.createElement(s); js.id = id;
        js.src = "//connect.facebook.net/en_US/sdk.js";
        fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));
</script>

<script>
$(window).load(function() {
    var comment_callback = function(response) {
        console.log("comment_callback");
        console.log(response);
    }
    FB.Event.subscribe('comment.create', comment_callback);
    FB.Event.subscribe('comment.remove', comment_callback);
});
</script>

Below are steps to update cocoapods :

1. Open terminal (Shortcut : Press cmd + space tab to open Spotlight then text in terminal)
2. Use command sudo gem install cocoapods. This will ask for system password due to security concern thereafter it installs gems

3. Now, set up pod using pod setup command. This will setup cocoapods master repo.

4. You can check the version of cocoapods using pod --version command.

All the other answers in here are also valid, but if none of them solve the issue it is also worth checking that the actual headers are being passed to the server.

i have used unset() to clear the array but i have come to realize that unset() will render the array null hence the need to re-declare the array like for example

<?php 
    $arr = array();
    array_push($arr , "foo");
    unset($arr); // this will set the array to null hence you need the line below or redeclaring it.
    $arr  = array();

    // do what ever you want here
?>

How to add single item. This is not very effective but follows what you are asking for:

x = p.Series()
N = 4
for i in xrange(N):
   x = x.set_value(i, i**2)

produces x:

0    0
1    1
2    4
3    9

Obviously there are better ways to generate this series in only one shot.

For your second question check answer and references of SO question add one row in a pandas.DataFrame.

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

In my case Handle.exe did not help. Simple program from official Microsoft called Process Explorer was useful. Just open as administrator and press Ctrl+f, type part of file name it will show process using file.

You can get the selected option this way:

$('#mySelectBox option:selected')...

LIVE DEMO

But if you want to iterate all the options, do it with this.selected instead of this.isChecked which doesn't exist:

$('#mySelectBox option').each(function() {
    if (this.selected)
       alert('this option is selected');
     else
       alert('this is not');
});

LIVE DEMO

Update:

You got plenty of answers suggesting you to use this:

$(this).is(':selected') well, it can be done a lot faster and easier with this.selected so why should you use it and not the native DOM element method?!

For DSA keys, use

 openssl dsa -pubin -in dsa.pub -modulus -noout

to print the public keys, then

 openssl dsa -in dsa.key -modulus -noout

to display the public keys corresponding to a private key, then compare them.

The way Blame moves around a bunch of software engineers working on different modules in a project.

First, the GUI guy gets blamed for the product not working. He checks his code and sees it's not his fault: the API is screwing up. The API guy checks his code: not his fault, it's a problem with the logger module. Logger module guy now blames database guy, who blames installer guy, who blames...

Now Microsoft is migrating to open-source - see CoreFX (GitHub).

I know you said you didn't want to read the file in by hand, but this is pretty easy

public class FooTest
{
    private BufferedReader in = null;

    @Before
    public void setup()
        throws IOException
    {
        in = new BufferedReader(
            new InputStreamReader(getClass().getResourceAsStream("/data.txt")));
    }

    @After
    public void teardown()
        throws IOException
    {
        if (in != null)
        {
            in.close();
        }

        in = null;
    }

    @Test
    public void testFoo()
        throws IOException
    {
        String line = in.readLine();

        assertThat(line, notNullValue());
    }
}

All you have to do is ensure the file in question is in the classpath. If you're using Maven, just put the file in src/test/resources and Maven will include it in the classpath when running your tests. If you need to do this sort of thing a lot, you could put the code that opens the file in a superclass and have your tests inherit from that.

DecimalFormat doesn't allow arbitrary text within the number to be formatted, just as a prefix or a suffix. So it won't be able to help you there.

In my opinion, storing a phone number as a numeric value is wrong, entirely. What if I want to store an international number? Many countries use + to indicate a country code (e.g. +1 for USA/Canda), others use 00 (e.g. 001).

Both of those can't really be represented in a numeric data type ("Is that number 1555123 or 001555123?")

Using attr() pointing to an external domain may trigger an error like this in Chrome: "Refused to display document because display forbidden by X-Frame-Options". The workaround to this can be to move the whole iframe HTML code into the script (eg. using .html() in jQuery).

Example:

var divMapLoaded = false;
$("#container").scroll(function() {
    if ((!divMapLoaded) && ($("#map").position().left <= $("#map").width())) {
    $("#map-iframe").html("<iframe id=\"map-iframe\" " +
        "width=\"100%\" height=\"100%\" frameborder=\"0\" scrolling=\"no\" " +
        "marginheight=\"0\" marginwidth=\"0\" " +
        "src=\"http://www.google.it/maps?t=m&amp;cid=0x3e589d98063177ab&amp;ie=UTF8&amp;iwloc=A&amp;brcurrent=5,0,1&amp;ll=41.123115,16.853177&amp;spn=0.005617,0.009943&amp;output=embed\"" +
        "></iframe>");
    divMapLoaded = true;
}

VonC's answer is best, but the part that worked for me was super simple and is kind of buried among a lot of other possible answers. If you are like me, you ran into this issue while running a "getting started with rails" tutorial and you had NOT setup your public/private SSH keys.

If so, try this:

1. $>cd ~/.ssh

2. $>ls

3. If the output of ls is known_hosts and nothing else, visit: http://help.github.com/mac-key-setup/ and start following the instructions from the "Generating a key" section and down.

After running those instructions, my "git push origin master" command worked.

Supposing the form is the direct parent you can do:

<a href='#' onclick='this.parentNode.submit(); return false;'>submit</a>

If not you can access through the forms name attribute like this:

<a href='#' onclick='document.forms["myform"].submit(); return false;'>submit</a>

See both examples here: http://jsfiddle.net/WEZDC/1/

The default port 1433 is used when there is only one SQL Server named instance running on the computer.

When multiple SQL Server named instances are running, they run by default under a dynamic port (49152–65535). In this scenario, an application will connect to the SQL Server Browser service port (UDP 1434) to get the dynamic port and then connect to the dynamic port directly.

You can download the sample file. Just place the html you want to convert in the files folder and run. It will automatically generate the pdf file and place it in the same folder. But in your case, you can specify your html path in the htmlFileName variable.

A variant using Bat/Powershell (need .net framework):

replace.bat :

@echo off

call:DoReplace "Findstr" "replacestr" test.txt test1.txt
exit /b

:DoReplace
echo ^(Get-Content "%3"^) ^| ForEach-Object { $_ -replace %1, %2 } ^| Set-Content %4>Rep.ps1
Powershell.exe -executionpolicy ByPass -File Rep.ps1
if exist Rep.ps1 del Rep.ps1
echo Done
pause

Add

<form target="_blank" ...></form>

or

form.setAttribute("target", "_blank");

to your form's definition.

My aurdino mega 2560 returned same error. It seems the problem exists in unofficial clones. The issue solved by pressing reset button just before uploading starts, as advertised in following video.

https://www.youtube.com/watch?v=tAzjO4v7oF4&list=LLDn5ewJDzz53IiwWmZTgQnQ&index=1

You can do one of two things:

1. Call getResources() and iterate through the returned collection of URLs, reading them as manifests until you find yours:

   Enumeration<URL> resources = getClass().getClassLoader()
     .getResources("META-INF/MANIFEST.MF");
   while (resources.hasMoreElements()) {
       try {
         Manifest manifest = new Manifest(resources.nextElement().openStream());
         // check that this is your manifest and do what you need or get the next one
         ...
       } catch (IOException E) {
         // handle
       }
   }
   

2. You can try checking whether getClass().getClassLoader() is an instance of java.net.URLClassLoader. Majority of Sun classloaders are, including AppletClassLoader. You can then cast it and call findResource() which has been known - for applets, at least - to return the needed manifest directly:

   URLClassLoader cl = (URLClassLoader) getClass().getClassLoader();
   try {
     URL url = cl.findResource("META-INF/MANIFEST.MF");
     Manifest manifest = new Manifest(url.openStream());
     // do stuff with it
     ...
   } catch (IOException E) {
     // handle
   }
   

Use:

AND oh.tran_date BETWEEN TRUNC(SYSDATE - 1) AND TRUNC(SYSDATE) - 1/86400

Reference: TRUNC

Calling a function on the tran_date means the optimizer won't be able to use an index (assuming one exists) associated with it. Some databases, such as Oracle, support function based indexes which allow for performing functions on the data to minimize impact in such situations, but IME DBAs won't allow these. And I agree - they aren't really necessary in this instance.

You have to validate the connection.

If you use Oracle it is likely that you use Oracle´s Universal Connection Pool. The following assumes that you do so.

The easiest way to validate the connection is to tell Oracle that the connection must be validated while borrowing it. This can be done with

pool.setValidateConnectionOnBorrow(true);

But it works only if you hold the connection for a short period. If you borrow the connection for a longer time, it is likely that the connection gets broken while you hold it. In that case you have to validate the connection explicitly with

if (connection == null || !((ValidConnection) connection).isValid())

See the Oracle documentation for further details.

Adding the lines below in the .typingsrc file helped me.

{
    "rejectUnauthorized": false,
    "registryURL" :"http://api.typings.org/"
 }

Just becuase your class object has no variables does not mean that it is nothing. Declaring and object and creating an object are two different things. Look and see if you are setting/creating the object.

Take for instance the dictionary object - just because it contains no variables does not mean it has not been created.

Sub test()

Dim dict As Object
Set dict = CreateObject("scripting.dictionary")

If Not dict Is Nothing Then
    MsgBox "Dict is something!"  '<--- This shows
Else
    MsgBox "Dict is nothing!"
End If

End Sub

However if you declare an object but never create it, it's nothing.

Sub test()

Dim temp As Object

If Not temp Is Nothing Then
    MsgBox "Temp is something!"
Else
    MsgBox "Temp is nothing!" '<---- This shows
End If

End Sub

Use ?? instead or {{ $usersType ?? '' }}

Code posted by you is correct and should have worked. But check exactly what you have in the char*. If the correct value is to big to be represented, functions will return a positive or negative HUGE_VAL. Check what you have in the char* against maximum values that float and double can represent on your computer.

Check this page for strtod reference and this page for atof reference.

I have tried the example you provided in both Windows and Linux and it worked fine.

When working with local packages, the only way I found to reliably regenerate the package-lock.json file is to delete it, as well as in the linked modules and all corresponding node_modules folders and let it be regenerated with npm i

If migrating constantly between two databases, then insert into an already existing table structure is a possibility. If so, then:

Use the following syntax:

insert into DESTINATION_DB.dbo.destination_table
select *
  from SOURCE_DB.dbo.source_table
[where x ...]

If migrating a LOT of tables (or tables with foreign keys constraints) I'd recommend:

• Generating Scripts with the Advanced option / Types of data to script : Data only OR
• Resort using a third party tool.

Hope it helps!

You can do it calling the DataTable.Copy() method, for example:

   DataSet ds = new DataSet();
   System.Data.DataTable dt = new System.Data.DataTable();
   dt = _BOSearchView.DS.Tables[BusLib.TPV.TableName.SearchView].Copy();
   ds.Tables.Add(dt);
   UltGrdSaleExcel.SetDataBinding(ds, dt.TableName, true);

I would recommend to use sftp, use this command sftp -oPort=7777 user@host where -oPort is custom port number of ssh , in case if u changed it to 7777, then u can use -oPort, else if use only port 22 then plain sftp user@host which asks for the password , then u can log in, and u can navigate to required location using cd /home/user then a simple command get table u can download it, If u want to download a directory/folder get -r someDirectory will do it. If u want the file permissions also to exist then get -Pr someDirectory. For uploading on to remote change get to put in above commands.

To avoid caching, one option is to give different URL for the same resource or data. To generate different URL, you can add a random query string to the end of the URL. This technique works for JQuery, Angular or other type ajax requests.

myURL = myURL +"?random="+new Date().getTime();

It's a generics literal. It means that you don't know the type of class this Class instance is representing, but you are still using the generic version.

• if you knew the class, you'd use Class<Foo>. That way you can create a new instance, for example, without casting: Foo foo = clazz.newInstance();
• if you don't use generics at all, you'll get a warning at least (and not using generics is generally discouraged as it may lead to hard-to-detect side effects)

A much simpler way to do this is to use vCenter Converter Standalone Client and do a P2V but in this case a V2V. It is much faster than copying the entire VM files onto some storage somewhere and copy it onto your new vCenter. It takes a long time to copy or exporting it to an OVF template and then import it. You can set your vCenter Converter Standalone Client to V2V in one step and synchronize and then have it power up the VM on the new Vcenter and shut off on the old vCenter. Simple.

For me using this method I was able to move a VM from one vCenter to another vCenter in about 30 minutes as compared to copying or exporting which took over 2hrs. Your results may vary.

This process below, from another responder, would work even better if you can present that datastore to ESXi servers on the vCenter and then follow step 2. Eliminating having to copy all the VMs then follow rest of the process.

1. Copy all of the cloned VM's files from its directory, and place it on its destination datastore.
2. In the VI client connected to the destination vCenter, go to the Inventory->Datastores view.
3. Open the datastore browser for the datastore where you placed the VM's files.
4. Find the .vmx file that you copied over and right-click it.
5. Choose 'Register Virtual Machine', and follow whatever prompts ensue. (Depending on your version of vCenter, this may be 'Add to Inventory' or some other variant)

I would ALWAYS go with both the alt and the title attributes. Many developers have been using this pattern now for over 20 years to deal with IE and other issues. So this is not new knowledge. Its just been rediscovered by new developers that didn't bother to learn from the past.

In addition, in HTML5 you should start using the new HTML5 picture element wrapped in figure with full WPA-ARIA attributes for greater accessibility, as well as support of assistive technologies, screen readers, and the like. Because this element is not supported in many older browsers...BUT degrades gracefully...I recommend the following HTML design pattern now for images in HTML:

<figure aria-labelledby="picturecaption2">
    <picture id="picture2">
        <source srcset="image.webp" type="image/webp" media="(min-width: 800px)" />
        <source srcset="image.gif" type="image/gif" />
        <img id="image2" style="height:auto;max-width: 100%;" src="image.jpg" width="255" height="200" alt="image:The World Wide Web" title="The World Wide Web" loading="lazy" no-referrer="no-referrer" onerror="this.onerror=null;" />
    </picture>
    <figcaption id="picturecaption2"><small>"My Cool Picture" [<a href="http://creativecommons.org/licenses/" target="_blank">A License</a>] , via <a href="https://commons.wikimedia.org/wiki/" target="_blank">Wikimedia Commons</a></small></figcaption>
</figure>

The code above has many extra "goodies" beside alt and title, including ARIA attributes, support for WebP, a media query supporting higher resolution imagery, and a nice fallback pattern supporting older image formats. It shows a fully decorated image example that uses new technologies while still supporting old ones with progressive design patterns.

REMEMBER...ALWAYS SUPPORT THE OLD BROWSERS!

I lost somehow my temporary notepad++ files, they weren't showing in tabs. So I did some search in appdata folder, and I found all my temporary files there. It seems that they are stored there for a long time.

C:\Users\USER\AppData\Roaming\Notepad++\backup

or

%AppData%\Notepad++\backup

//Component. home.ts :

  contacts:IContacts[];


ionViewDidLoad() {
this.rest.getContacts()
.subscribe( res=> this.contacts= res as IContacts[]) ;

// reorderArray. accepts only Arrays

    Reorder(indexes){
  reorderArray(this.contacts, indexes)
}

// Service . res.ts

getContacts(): Observable<IContacts[]> {
return this.http.get<IContacts[]>(this.apiUrl+"?results=5")

And it works fine

This is actually on the main page of nltk.org:

>>> import nltk
>>> sentence = """At eight o'clock on Thursday morning
... Arthur didn't feel very good."""
>>> tokens = nltk.word_tokenize(sentence)
>>> tokens
['At', 'eight', "o'clock", 'on', 'Thursday', 'morning',
'Arthur', 'did', "n't", 'feel', 'very', 'good', '.']

There is another approach with the MQ extension and the debug commands. This is a general way to modify history without losing data. Let me assume the same situation as Antonio.

// set current tip to rev 497
hg debugsetparents 497
hg debugrebuildstate
// hg add/remove if needed
hg commit
hg strip [-n] 498

Also remember that it must be:

#include "stdafx.h"
#include <iostream>

and not the other way around

#include <iostream>
#include "stdafx.h"

But if your Android App is only for personal purpose or created by you alone, you can use:

me.app_name.app

Nobody mentions the similar but even simpler solution than above with no need to deal with the package of the class. Assuming myfile.properties is in the classpath.

        Properties properties = new Properties();
        InputStream in = ClassLoader.getSystemResourceAsStream("myfile.properties");
        properties.load(in);
        in.close();

1) If you haven't installed mongodb, install it.

2) open a new terminal, type "mongo". This is going to connect you to a MongoDB instance running on your localhost with default port 27017:

I think the best solution I have come across is on this stackoverflow. This short jQuery code allows all your hover effects to show on click or touch..
No need to add anything within the function.

$('body').on('touchstart', function() {});

Hope this helps.

private void buttonRemove_Click(object sender, EventArgs e)
{
    foreach (DataGridViewCell oneCell in dataGridView1.SelectedCells)
    {
        if (oneCell.Selected)
            dataGridView1.Rows.RemoveAt(oneCell.RowIndex);
    }
}

Removes rows which indexes are in selected cells. So, select any cells, and their corresponding rows will be removed.

Another way to get the density loaded by the device:

Create values folders for each density

• values (default mdpi)
• values-hdpi
• values-xhdpi
• values-xxhdpi
• values-xxxhdpi

Add a string resource in their respective strings.xml:

<string name="screen_density">MDPI</string>    <!-- ..\res\values\strings.xml -->
<string name="screen_density">HDPI</string>    <!-- ..\res\values-hdpi\strings.xml -->
<string name="screen_density">XHDPI</string>   <!-- ..\res\values-xhdpi\strings.xml -->
<string name="screen_density">XXHDPI</string>  <!-- ..\res\values-xxhdpi\strings.xml -->
<string name="screen_density">XXXHDPI</string> <!-- ..\res\values-xxxhdpi\strings.xml -->

Then simply get the string resource, and you have your density:

String screenDensity = getResources().getString(R.string.screen_density);

If the density is larger than XXXHDPI, it will default to XXXHDPI or if it is lower than HDPI it will default to MDPI

I left out LDPI, because for my use case it isn't necessary.

Read the binary file content like this:

with open(fileName, mode='rb') as file: # b is important -> binary
    fileContent = file.read()

then "unpack" binary data using struct.unpack:

The start bytes: struct.unpack("iiiii", fileContent[:20])

The body: ignore the heading bytes and the trailing byte (= 24); The remaining part forms the body, to know the number of bytes in the body do an integer division by 4; The obtained quotient is multiplied by the string 'i' to create the correct format for the unpack method:

struct.unpack("i" * ((len(fileContent) -24) // 4), fileContent[20:-4])

The end byte: struct.unpack("i", fileContent[-4:])

MySQL has 4 levels of collation: server, database, table, column. If you change the collation of the server, database or table, you don't change the setting for each column, but you change the default collations.

E.g if you change the default collation of a database, each new table you create in that database will use that collation, and if you change the default collation of a table, each column you create in that table will get that collation.

var theName;

theName = $("input selector goes here").attr("name");

Try this:

dir /s /b /o:n /ad > f.txt

I think I know why you want to avoid that. But maybe try & catch !== try & catch. ;o) This came into my mind:

var json_verify = function(s){ try { JSON.parse(s); return true; } catch (e) { return false; }};

So you may also dirty clip to the JSON object, like:

JSON.verify = function(s){ try { JSON.parse(s); return true; } catch (e) { return false; }};

As this as encapsuled as possible, it may not break on error.

The uuid module provides immutable UUID objects (the UUID class) and the functions uuid1(), uuid3(), uuid4(), uuid5() for generating version 1, 3, 4, and 5 UUIDs as specified in RFC 4122.

If all you want is a unique ID, you should probably call uuid1() or uuid4(). Note that uuid1() may compromise privacy since it creates a UUID containing the computer’s network address. uuid4() creates a random UUID.

Docs:

• Python 2
• Python 3

Example (for both Python 2 and 3):

>>> import uuid
>>> uuid.uuid4()
UUID('bd65600d-8669-4903-8a14-af88203add38')
>>> str(uuid.uuid4())
'f50ec0b7-f960-400d-91f0-c42a6d44e3d0'
>>> uuid.uuid4().hex
'9fe2c4e93f654fdbb24c02b15259716c'

You can use

adb shell ps | grep apps | awk '{print $9}'

to produce an output like:

com.google.process.gapps
com.google.android.apps.uploader
com.google.android.apps.plus
com.google.android.apps.maps
com.google.android.apps.maps:GoogleLocationService
com.google.android.apps.maps:FriendService
com.google.android.apps.maps:LocationFriendService

adb shell ps returns a list of all running processes on the android device, grep apps searches for any row with contains "apps", as you can see above they are all com.google.android.APPS. or GAPPS, awk extracts the 9th column which in this case is the package name.

To search for a particular package use

adb shell ps | grep PACKAGE.NAME.HERE | awk '{print $9}'

i.e adb shell ps | grep com.we7.player | awk '{print $9}'

If it is running the name will appear, if not there will be no result returned.

For me, setting JAVA_HOME did the trick (instead of unsetting, as in another answer given here). Either in Windows:

set JAVA_HOME="C:\Program Files\Java\jre7\"

Or inside R:

Sys.setenv(JAVA_HOME="C:\\Program Files\\Java\\jre7\\")

But what's probably the best solution (since rJava 0.9-4) is overriding within R the Windows JAVA_HOME setting altogether:

options(java.home="C:\\Program Files\\Java\\jre7\\")
library(rJava)

<> will surely give you all values not equal to 5. If you have more than one record in table it will give you all except 5. If on the other hand you have only one, you will get surely one. Give the table schema so that one can help you properly

Some of the answers no longer work as explained.

Currently here is something that works for me in ansible 2.6.x

Have you tried using Project > Clean... from the menu? This will force a new build on the selected projects in Eclipse.

You have to refer to the documentation for ctime. time is a function that takes one parameter of type time_t * (a pointer to a time_t object) and assigns to it the current time. Instead of passing this pointer, you can also pass NULL and then use the returned time_t value instead.

Please use this command and try :

redis-cli --raw keys "$PATTERN" | xargs redis-cli del

Use the Microsoft Anti-XSS library which includes a JavaScript encode.

function isset(element) {
    return element.length > 0;
}

http://jsfiddle.net/8KYxe/1/

Or, as a jQuery extension:

$.fn.exists = function() { return this.length > 0; };

// later ...
if ( $("#id").exists() ) {
  // do something
}

That's correct, your response is an object with fields:

{
    "page": 1,
    "results": [ ... ]
}

So you in fact want to iterate the results field only:

this.data = res.json()['results'];

... or even easier:

this.data = res.json().results;

Set Current State first ...this.state

Its because when you are going to assign a new state it may be undefined. so it will be fixed by setting state extracting current state also

this.setState({...this.state, field})

If there is an object in your state, you should set state as follows, suppose you have to set username inside the user object.

this.setState({user:{...this.state.user, ['username']: username}})

This can also be achieved by Ctrl+WindowsBtn+Alt+L. This will be important to some people,because in some Virtual Machines, Ctrl+Alt+L can log you out.

declare class & nested struct probably in some header file

class C {
    // struct will be private without `public:` keyword
    struct S {
        // members will be public without `private:` keyword
        int sa;
        void func();
    };
    void func(S s);
};

if you want to separate the implementation/definition, maybe in some CPP file

void C::func(S s) {
    // implementation here
}
void C::S::func() { // <= note that you need the `full path` to the function
    // implementation here
}

if you want to inline the implementation, other answers will do fine.

Here's one with extend()

types = ('*.jpg', '*.png')
images_list = []
for files in types:
    images_list.extend(glob.glob(os.path.join(path, files)))

truncate tableName

That is what you are looking for.

Truncate will delete all records in the table, emptying it.

Setup a ts project as following steps:

• install typescript yarn global add typescript
• create a package.json: run yarn init or setting defaults yarn init -yp
• create a tsconfig.json: run tsc --init
• (*optional) add tslint.json

The project structure seems like:

¦  package.json
¦  tsconfig.json
¦  tslint.json
¦  yarn.lock
¦
+-dist
¦      index.js
¦
+-src
       index.ts

There's a very nice discussion of this specific problem over at MIT. On page 5, they make the point that, if you assume that an addition takes one computational unit, the time required to compute Fib(N) is very closely related to the result of Fib(N).

As a result, you can skip directly to the very close approximation of the Fibonacci series:

Fib(N) = (1/sqrt(5)) * 1.618^(N+1) (approximately)

and say, therefore, that the worst case performance of the naive algorithm is

O((1/sqrt(5)) * 1.618^(N+1)) = O(1.618^(N+1))

PS: There is a discussion of the closed form expression of the Nth Fibonacci number over at Wikipedia if you'd like more information.

This might help..!!!

Synchronized Vs Atomic Vs Volatile:

• Volatile and Atomic is apply only on variable , While Synchronized apply on method.
• Volatile ensure about visibility not atomicity/consistency of object , While other both ensure about visibility and atomicity.
• Volatile variable store in RAM and it’s faster in access but we can’t achive Thread safety or synchronization whitout synchronized keyword.
• Synchronized implemented as synchronized block or synchronized method while both not. We can thread safe multiple line of code with help of synchronized keyword while with both we can’t achieve the same.
• Synchronized can lock the same class object or different class object while both can’t.

Please correct me if anything i missed.

Inflate a custom layout. Use a view holder for smooth scrolling and performance.

http://developer.android.com/training/improving-layouts/smooth-scrolling.html

http://www.youtube.com/watch?v=wDBM6wVEO70. The talk is about listview performance by android developers.

Apart from the options suggested by other people:

show collections  // Output every collection
show tables
db.getCollectionNames() // Shows all collections as a list

There is also another way which can be really handy if you want to know how each of the collections was created (for example, it is a capped collection with a particular size):

db.system.namespaces.find()

sudo gem install cocoapods --pre -n /usr/local/bin

This works for me.

Maybe the condition you are using is incorrect:

$str1 == "taste" && $str2 == "waste"

The program will enter into THEN part only when both of the stated conditions are true.

You can try with $str1 == "taste" || $str2 == "waste". This will execute the THEN part if anyone of the above conditions are true.

Because I just went through this - I wanted to give my solution even though this is a bit old.

I have several computers on a home router and I have been working on some projects for myself. Well, I wanted to see what it looked like on my mobil devices. But WAMP was set so I could only get on from the development system. So I began looking around and found this article as well as some others. The problem is - none of them worked for me. So I was left to figure this out on my own.

My solution:

First, in the HTTPD.CONF file you need to add one line to the end of the list of what devices are allowed to access your WAMP server. So instead of:

#    Require all granted
#   onlineoffline tag - don't remove
     Order Deny,Allow
     Deny from all
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost

make it:

#    Require all granted
#   onlineoffline tag - don't remove
     Order Deny,Allow
     Deny from all
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost
     Allow from 192.168.78

The above says that any device that is on your router (the '78' is just an arbitrary number picked for this solution. It should be whatever your router is set up for. So it might be 192.168.1 or 192.168.0 or even 192.168.254 - you have to look it up on your router.) can now access your server.

The above did NOT do anything for me - at first. There is more you need to do. But first - what you do NOT need to do. You do NOT need to change the WAMP setting from Offline to Online. FOR ME - changing that setting doesn't do anything. Unknown why - it just doesn't. So change it if you want - but I don't think it needs to be changed.

So what else DOES need to be changed? You have to go all the way back to the beginning of the httpd.conf file for this next change and it is really simple. You have to add a new line after the

Listen Localhost:80

add

Listen 192.168.78.###:80

Where the "###" is what IP your server is on. So let's say your server is on IP number 234. Then the above command would become

Listen localhost:80
Listen 192.168.78.234:80

Again - the '78' is just an arbitrary number I picked. To get your real IP number you have to open a command window and type in

ipconfig/all

command. Look for what your TCP/IPv4 number is and set it to that number or TCP/IPv6 if that is all you have (although on internal router sets you usually have an IPv4 number).

Note: In case you do not know how to bring up a command window - you click on Start, select the "Run" option, and type "cmd.exe" in to the dialog box without the quotes. On newer systems (since they keep changing everything) it might be the white windows icon or the circle or Bill Gates jumping up and down. Whatever it is - click on it.

Once you have done the above - restart all services and everything should come up just fine.

Finally - why? Why do you have to change the Listen command? It has to do with localhost. 'localhost' is set to 127.0.0.1 and NOT your IP address by default. This can be found in your host file which is usually found in the system32 folder under Windows but probably has been moved by Microsoft to somewhere else. Look it up online for where it is and go look at it. If you see a lot of sex, porn, etc sites in your localhost host file - you need to get rid of them (unless that is your thing). I suggest RogueKiller (at AdLice.com) be used to take a look at your system because it can reset your host file for you.

If your host file is normal though - it should contain just one entry and that entry is to set localhost to 127.0.0.1. That is why using localhost in the httpd.conf file makes it so you only can work on everything and see everything from your server computer.

So if you feel adventurous - change your host file and leave the Listen command alone OR just change the Listen command to listen to port 80 on your server.

NEW (I forgot to put in this part)

You MAY have to change your TCP/IP address. (Mine is already set up so I didn't need to do this.) You will need to look up for your OS how to get to where your TCP/IP address is defined. Under Windows XP this was Control Panel->Network Connections. This has changed in later OSs so you have to look up how to get there. Anyway, once there you will see your Wireless Network Connection or Local Area Connection (Windows). Basically WIFI or Ethernet cable. Select the one that is active and in use. Under Windows you then right-click and select Properties. A dialog should pop-up and you should see a list of checkboxes with what they are to the side. Look for the one that is for TCP/IP. There should be one that says TCP/IP v4. Select it. (If there isn't one - you should proceed with caution.) Click the Properties button and you should get another dialog box. This one shows either "Obtain an IP address automatically" or "Use the following IP address" selected. If it is the first one then you have to change it to the second one. BUT BEFORE YOU DO THAT - bring up a command window and type in the ipcongfig/all command so you have, right there in front of you, what your default gateway is. Then change it from "Obtain..." to "Use...". Where it says "IP address" put in the IP address you want to always use. This is the IP address you put in on the Listen command above. The second line (Subnet mask) usually is 255.255.255.0 meaning only the last number (ie: 0) changes. Then, looking back at the command window put in your default gateway. Last, but not least, when you changed from "Obtain..." to "Use..." the DNS settings may have changed. If the section which deals with DNS settings has changed to "Use..." and it is blank - the answer is simple. Just look at that ipconfig/all output, find the DNS setting(s) there and put them in to the fields provided. Once done click the OK button and then click the second OK button. Once the dialog closes you may have to reboot your system for the changes to take effect. Try it out by going to Google or Stack Overflow. If you can still go places - then no reboot is required. Otherwise, reboot. Remember! If you can't get on the internet afterwards all you do is go back and reset everything to the "Obtain..." option. The most likely reason, after making the changes, that you can no longer get on the internet is because the TCP/IP address you chose to use is already in use by the router. The saying "There can be only one" goes for TCP/IP addresses too. This is why I always pick a high one-hundreds number or a low two-hundreds number. Because most DHCP set ups use numbers less than fifty. So in this way you don't collide with someone else's TCP/IP number.

This is how I fixed my problem.

Using can also use Java 8 stream API and do the same thing in one line.

If you want to print any specific property then use this syntax:

ArrayList<Room> rooms = new ArrayList<>();
rooms.forEach(room -> System.out.println(room.getName()));

OR

ArrayList<Room> rooms = new ArrayList<>();
rooms.forEach(room -> {
    // here room is available
});

if you want to print all the properties of Java object then use this:

ArrayList<Room> rooms = new ArrayList<>();
rooms.forEach(System.out::println);

However many years late this response may be, anyone coming across this might just want to try

li {
    display: flex;
    flex-direction: row;
    align-items: center;
}

Browser support for flexbox is far better than it was when @scottjoudry posted his response above, but you may still want to consider prefixing or other options if you're trying to support much older browsers. caniuse: flex

Probably the mymobileNO.titleLabel.text value doesn't include the scheme tel://

Your code should look like this:

NSString *phoneNumber = [@"tel://" stringByAppendingString:mymobileNO.titleLabel.text];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:phoneNumber]];

Because they are two different kinds of controls...

You see, your web browser doesn't know about server side programming. it only knows about it's own DOM and the event models that it uses... And for click events of objects rendered to it. You should examine the final markup that is actually sent to the browser from ASP.Net to see the differences your self.

<asp:CheckBox runat="server" OnClick="alert(this.checked);" />

renders to

<input type="check" OnClick="alert(this.checked);" />

and

<asp:CheckBox runat="server" OnClientClick="alert(this.checked);" />

renders to

<input type="check" OnClientClick="alert(this.checked);" />

Now, as near as i can recall, there are no browsers anywhere that support the "OnClientClick" event in their DOM...

When in doubt, always view the source of the output as it is sent to the browser... there's a whole world of debug information that you can see.

It's recommended to put the image to the resources, than you can use it like this:

imageView = new ImageView("/gui.img/img.jpg");

If you can organize the values in the array in sorted order, then you can use Arrays.binarySearch(). Otherwise you'll have to write a loop and to a linear search. If you plan to have a large (more than a few dozen) strings in the array, consider using a Set instead.

Look at this awesome new library which is available via gradle :)

build.gradle: compile 'com.apptakk.http_request:http-request:0.1.2'

Usage:

new HttpRequestTask(
    new HttpRequest("http://httpbin.org/post", HttpRequest.POST, "{ \"some\": \"data\" }"),
    new HttpRequest.Handler() {
      @Override
      public void response(HttpResponse response) {
        if (response.code == 200) {
          Log.d(this.getClass().toString(), "Request successful!");
        } else {
          Log.e(this.getClass().toString(), "Request unsuccessful: " + response);
        }
      }
    }).execute();

Or did you want to just see if a column only has NULL values (and, thus, is probably unused)?

Further clarification of the question might help.

EDIT: Ok.. here's some really rough code to get you going...

SET NOCOUNT ON
DECLARE @TableName Varchar(100)
SET @TableName='YourTableName'
CREATE TABLE #NullColumns (ColumnName Varchar(100), OnlyNulls BIT)
INSERT INTO #NullColumns (ColumnName, OnlyNulls) SELECT c.name, 0 FROM syscolumns c INNER JOIN sysobjects o ON c.id = o.id AND o.name = @TableName AND o.xtype = 'U'
DECLARE @DynamicSQL AS Nvarchar(2000)
DECLARE @ColumnName Varchar(100)
DECLARE @RC INT
    SELECT TOP 1 @ColumnName = ColumnName FROM #NullColumns WHERE OnlyNulls=0
    WHILE @@ROWCOUNT > 0
    BEGIN
        SET @RC=0
        SET @DynamicSQL = 'SELECT TOP 1 1 As HasNonNulls FROM ' + @TableName + ' (nolock) WHERE ''' + @ColumnName + ''' IS NOT NULL'
        EXEC sp_executesql @DynamicSQL
        set @RC=@@rowcount
        IF @RC=1
        BEGIN
            SET @DynamicSQL = 'UPDATE #NullColumns SET OnlyNulls=1 WHERE ColumnName=''' + @ColumnName + ''''
            EXEC sp_executesql @DynamicSQL
        END
        ELSE
        BEGIN
            SET @DynamicSQL = 'DELETE FROM #NullColumns WHERE ColumnName=''' + @ColumnName+ ''''
            EXEC sp_executesql @DynamicSQL
        END
    SELECT TOP 1 @ColumnName = ColumnName FROM #NullColumns WHERE OnlyNulls=0
    END

SELECT * FROM #NullColumns

DROP TABLE #NullColumns
SET NOCOUNT OFF

Yes, there are easier ways, but I have a meeting to go to right now. Good luck!

You should watch this: Node Tuts episode 19 - Asynchronous Iteration Patterns

It should answers your questions.

You can resave the image and literally find the src file of your project and add it to that when you save. For me I had to go to netbeans and found my project and when that comes up it had 3 files src was the last. Don't click on any of them just save your pic there. That should work. Now resizing it may be a different issue and one I'm working on now lol

in fork(), either child or parent process will execute based on cpu selection.. But in vfork(), surely child will execute first. after child terminated, parent will execute.

In my case, the problem was that I had set my DataSource as an object, which is why it didn't get sorted. After changing from object to a DataTable it workd well without any code complement.

Update with psycopg2 2.7:

The classic executemany() is about 60 times slower than @ant32 's implementation (called "folded") as explained in this thread: https://www.postgresql.org/message-id/20170130215151.GA7081%40deb76.aryehleib.com

This implementation was added to psycopg2 in version 2.7 and is called execute_values():

from psycopg2.extras import execute_values
execute_values(cur,
    "INSERT INTO test (id, v1, v2) VALUES %s",
    [(1, 2, 3), (4, 5, 6), (7, 8, 9)])

Previous Answer:

To insert multiple rows, using the multirow VALUES syntax with execute() is about 10x faster than using psycopg2 executemany(). Indeed, executemany() just runs many individual INSERT statements.

@ant32 's code works perfectly in Python 2. But in Python 3, cursor.mogrify() returns bytes, cursor.execute() takes either bytes or strings, and ','.join() expects str instance.

So in Python 3 you may need to modify @ant32 's code, by adding .decode('utf-8'):

args_str = ','.join(cur.mogrify("(%s,%s,%s,%s,%s,%s,%s,%s,%s)", x).decode('utf-8') for x in tup)
cur.execute("INSERT INTO table VALUES " + args_str)

Or by using bytes (with b'' or b"") only:

args_bytes = b','.join(cur.mogrify("(%s,%s,%s,%s,%s,%s,%s,%s,%s)", x) for x in tup)
cur.execute(b"INSERT INTO table VALUES " + args_bytes) 

I looked around for an answer to this and the best way I found was to use Flex and inline styling on different components.

For example, to make two paper components divide my full screen in 2 vertical components (in ration of 1:4), the following code works fine.

const styles = {
  div:{
    display: 'flex',
    flexDirection: 'row wrap',
    padding: 20,
    width: '100%'
  },
  paperLeft:{
    flex: 1,
    height: '100%',
    margin: 10,
    textAlign: 'center',
    padding: 10
  },
  paperRight:{
    height: 600,
    flex: 4,
    margin: 10,
    textAlign: 'center',
  }
};

class ExampleComponent extends React.Component {
  render() {
    return (
      <div>
        <div style={styles.div}>
          <Paper zDepth={3} style={styles.paperLeft}>

Now, with some more calculations, you can easily divide your components on a page.

For me, I couldn't get this to return a hash.

results = ActiveRecord::Base.connection.execute(sql)

But using the exec_query method worked.

results = ActiveRecord::Base.connection.exec_query(sql)

Use $dec = $null

From the documentation:

$null is an automatic variable that contains a NULL or empty value. You can use this variable to represent an absent or undefined value in commands and scripts.

PowerShell treats $null as an object with a value, that is, as an explicit placeholder, so you can use $null to represent an empty value in a series of values.

POJO stands for Plain Old Java Object, and would be used to describe the same things as a "Normal Class" whereas a JavaBean follows a set of rules. Most commonly Beans use getters and setters to protect their member variables, which are typically set to private and have a no-argument public constructor. Wikipedia has a pretty good rundown of JavaBeans: http://en.wikipedia.org/wiki/JavaBeans

POJO is usually used to describe a class that doesn't need to be a subclass of anything, or implement specific interfaces, or follow a specific pattern.

As noted the Ajax and effects modules have been excluded from jQuery slim the size difference as of 3.3.1 for the minified version unzipped is 85k vs 69k (16k saving for slim) or 30vs24 for zipped, it is important to note that bootstrap 4 uses the slim jQuery so if someone wants the full version they need to call that instead

Let's say you have a url like this http://www.example.com/controller/action/arg1/arg2

If you want to know what are the arguments that are being passed in this url

$param_offset=0;
$params = array_slice($this->uri->rsegment_array(), $param_offset);
var_dump($params);

Output will be:

array (size=2)
  0 => string 'arg1'
  1 => string 'arg2'

This has been here quite a while but posting this. Might be useful for someone.

@RequestMapping( "/{id}/**" )
public void foo( @PathVariable String id, HttpServletRequest request ) {
    String urlTail = new AntPathMatcher()
            .extractPathWithinPattern( "/{id}/**", request.getRequestURI() );
}

I think most people want their placeholder text to be in grey and appear only once, so this is what I did:

1. Set your color in viewDidLoad() (not in IB)

   commentsTextView.textColor = UIColor.darkGray
   

2. Implement UITextViewDelegate to your controller

3. add function to your controller

   func textViewDidBeginEditing(_ textView: UITextView) {
       if (commentsTextView.textColor == UIColor.darkGray) {
          commentsTextView.text = ""
          commentsTextView.textColor = UIColor.black
       }
   }
   

This solution is simple.

If you are using react-router-dom and material-ui you can use ...

import { Link } from 'react-router-dom'
import Button from '@material-ui/core/Button';

<Button component={Link} to="/open-collective">
  Link
</Button>

I did it by putting

export JAVA_HOME=`/usr/libexec/java_home`

(backtics) in my .bashrc. See my comment on Adrian's answer.

client = new OkHttpClient();

        Request request = new Request.Builder().header("authorization", token).url(url).build();
        MyWebSocketListener wsListener = new MyWebSocketListener(LudoRoomActivity.this);
        client.newWebSocket(request, wsListener);
        client.dispatcher().executorService().shutdown();

Historically I always solved this by deleting the pending migrations, or if there was only 1 remaining and it was mostly desirable, by using -f to recreate it.

Recently, this has stopped working for me.

When this happened the first time, I restarted Visual Studio, and then it let me proceed.

The second time, it only worked after I ran a Clean on the project. It was almost as if the pending migrations were retained despite deleting all the files from explorer.

even I faced the same issue. I rectified it by going to the particular client under the realm respectively therein redirect URL add * after your complete URL.

THE PROBLEM WILL BE SOLVED

Example: redirect URI: http:localhost:3000/myapp/generator/*

There is a great checklist found on Github:

Authentication

• Don't reinvent the wheel in Authentication, token generation, password storage. Use the standards.

• Use Max Retry and jail features in Login.

• Use encryption on all sensitive data.

JWT (JSON Web Token)

• Use a random complicated key (JWT Secret) to make brute forcing the token very hard.

• Don't extract the algorithm from the payload. Force the algorithm in the backend (HS256 or RS256).

• Make token expiration (TTL, RTTL) as short as possible.

• Don't store sensitive data in the JWT payload, it can be decoded easily.

OAuth

• Always validate redirect_uri server-side to allow only whitelisted URLs.

• Always try to exchange for code and not tokens (don't allow response_type=token).

• Use state parameter with a random hash to prevent CSRF on the OAuth authentication process.

• Define the default scope, and validate scope parameters for each application.

Access

• Limit requests (Throttling) to avoid DDoS / brute-force attacks.

• Use HTTPS on server side to avoid MITM (Man In The Middle Attack)

• Use HSTS header with SSL to avoid SSL Strip attack.

Input

• Use the proper HTTP method according to the operation: GET (read), POST (create), PUT/PATCH (replace/update), and DELETE (to delete a record), and respond with 405 Method Not Allowed if the requested method isn't appropriate for the requested resource.

• Validate content-type on request Accept header (Content Negotiation) to allow only your supported format (e.g. application/xml, application/json, etc) and respond with 406 Not Acceptable response if not matched.

• Validate content-type of posted data as you accept (e.g. application/x-www-form-urlencoded, multipart/form-data, application/json, etc).

• Validate User input to avoid common vulnerabilities (e.g. XSS, SQL-Injection, Remote Code Execution, etc).

• Don't use any sensitive data (credentials, Passwords, security tokens, or API keys) in the URL, but use standard Authorization header.

• Use an API Gateway service to enable caching, Rate Limit policies (e.g. Quota, Spike Arrest, Concurrent Rate Limit) and deploy APIs resources dynamically.

Processing

• Check if all the endpoints are protected behind authentication to avoid broken authentication process.

• User own resource ID should be avoided. Use /me/orders instead of /user/654321/orders.

• Don't auto-increment IDs. Use UUID instead.

• If you are parsing XML files, make sure entity parsing is not enabled to avoid XXE (XML external entity attack).

• If you are parsing XML files, make sure entity expansion is not enabled to avoid Billion Laughs/XML bomb via exponential entity expansion attack.

• Use a CDN for file uploads.

• If you are dealing with huge amount of data, use Workers and Queues to process as much as possible in background and return response fast to avoid HTTP Blocking.

• Do not forget to turn the DEBUG mode OFF.

Output

• Send X-Content-Type-Options: nosniff header.

• Send X-Frame-Options: deny header.

• Send Content-Security-Policy: default-src 'none' header.

• Remove fingerprinting headers - X-Powered-By, Server, X-AspNet-Version etc.

• Force content-type for your response, if you return application/json then your response content-type is application/json.

• Don't return sensitive data like credentials, Passwords, security tokens.

• Return the proper status code according to the operation completed. (e.g. 200 OK, 400 Bad Request, 401 Unauthorized, 405 Method Not Allowed, etc).

Try setting:

android:indeterminateDrawable="@drawable/progress" 

It worked for me. Here is also the code for progress.xml:

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:pivotX="50%" android:pivotY="50%" android:fromDegrees="0"
    android:toDegrees="360">

    <shape android:shape="ring" android:innerRadiusRatio="3"
        android:thicknessRatio="8" android:useLevel="false">

        <size android:width="48dip" android:height="48dip" />

        <gradient android:type="sweep" android:useLevel="false"
            android:startColor="#4c737373" android:centerColor="#4c737373"
            android:centerY="0.50" android:endColor="#ffffd300" />

    </shape>

</rotate> 

The code is okay but you are in the wrong directory. You must run these commands inside your rails project-directory.

The normal way to get there from scratch is:

$ rails new PROJECT_NAME
$ cd PROJECT_NAME
$ rails generate model ad \
    name:string \ 
    description:text \
    price:decimal \
    seller_id:integer \
    email:string img_url:string

If the string is Unicode the easiest way is:

import base64                                                        

a = base64.b64encode(bytes(u'complex string: ñáéíóúÑ', "utf-8"))

# a: b'Y29tcGxleCBzdHJpbmc6IMOxw6HDqcOtw7PDusOR'

b = base64.b64decode(a).decode("utf-8", "ignore")                    

print(b)
# b :complex string: ñáéíóúÑ

Another solution using java.nio.file:

byte[] bytes = ...;
Path path = Paths.get("C:\\myfile.pdf");
Files.write(path, bytes);

<?php if ($my_name == 'aboutme') { ?>
    HTML_GOES_HERE
<?php } ?>

You use the lpMultiByteStr [out] parameter by creating a new char array. You then pass this char array in to get it filled. You only need to initialize the length of the string + 1 so that you can have a null terminated string after the conversion.

Here are a couple of useful helper functions for you, they show the usage of all parameters.

#include <string>

std::string wstrtostr(const std::wstring &wstr)
{
    // Convert a Unicode string to an ASCII string
    std::string strTo;
    char *szTo = new char[wstr.length() + 1];
    szTo[wstr.size()] = '\0';
    WideCharToMultiByte(CP_ACP, 0, wstr.c_str(), -1, szTo, (int)wstr.length(), NULL, NULL);
    strTo = szTo;
    delete[] szTo;
    return strTo;
}

std::wstring strtowstr(const std::string &str)
{
    // Convert an ASCII string to a Unicode String
    std::wstring wstrTo;
    wchar_t *wszTo = new wchar_t[str.length() + 1];
    wszTo[str.size()] = L'\0';
    MultiByteToWideChar(CP_ACP, 0, str.c_str(), -1, wszTo, (int)str.length());
    wstrTo = wszTo;
    delete[] wszTo;
    return wstrTo;
}

Anytime in documentation when you see that it has a parameter which is a pointer to a type, and they tell you it is an out variable, you will want to create that type, and then pass in a pointer to it. The function will use that pointer to fill your variable.

So you can understand this better:

//pX is an out parameter, it fills your variable with 10.
void fillXWith10(int *pX)
{
  *pX = 10;
}

int main(int argc, char ** argv)
{
  int X;
  fillXWith10(&X);
  return 0;
}

It depends on how you validate your XML. If you use XML Schema validation, the correct way of representing null values is with the xsi:nil attribute.

To set white colour of the image(arrow icon) on the button, we're using:

let imageOnButton = UIImage(named: "navForwardArrow")?.imageWithColor(color: UIColor.white)
button.setImage(imageOnButton, for: .normal)

Known issue: The icon looses its white colour while the button is pressed.

Screenshot:

If you need to update global property, a simple getter/setter wrapper class can be used as global variable. A typical example is shown below.

public class GlobalHolder {

    private static final GlobalHolder INSTANCE = new GlobalHolder();

    private volatile int globalProperty;

    public static GlobalHolder getInstance() {
        return INSTANCE;
    }

    public int getGlobalProperty() {
        return globalProperty;
    }

    public void setGlobalProperty(int globalProperty) {
        this.globalProperty = globalProperty;
    }

    public static void main(String[] args) {
        GlobalHolder.getInstance().setGlobalProperty(10);
        System.out.println(GlobalHolder.getInstance().getGlobalProperty());
    }
}

A bit old, but I was still getting the same SettingWithCopyWarning. Here was my solution:

df.loc[:, 'quantity'] = df['quantity'] * -1

select COUNT(*)
from Monitor as m
    inner join Monitor_Request as mr on mr.Company_ID=m.Company_id
    group by m.Company_id
    having COUNT(m.Monitor_id)>=5
