Suppose you want to give attributes to an instance which was previously not written in code. The setattr() does just that. It takes the instance of the class self and key and value to set.

class Example:
    def __init__(self, **kwargs):
        for key, value in kwargs.items():
            setattr(self, key, value)

To add the privileges needed to the files add and grant right to the following local user: SQLServerMSSQLUser$COMPUTERNAME$INSTANCENAME, where COMPUTERNAME and INSTANCENAME has to be replaced with name of computer and MSSQL instance respectively.

you can achieve this by adding "::before" Pseudo-element

Pure CSS Trick ;)

For await/async aiounittest there is a slightly different pattern:

https://aiounittest.readthedocs.io/en/latest/asynctestcase.html#aiounittest.AsyncTestCase

async def test_await_async_fail(self):
    with self.assertRaises(Exception) as e:
        await async_one()

Based on what I read from different sources:

An await expression does not block the thread on which it is executing. Instead, it causes the compiler to sign up the rest of the async method as a continuation on the awaited task. Control then returns to the caller of the async method. When the task completes, it invokes its continuation, and execution of the async method resumes where it left off.

To wait for a single task to complete, you can call its Task.Wait method. A call to the Wait method blocks the calling thread until the single class instance has completed execution. The parameterless Wait() method is used to wait unconditionally until a task completes. The task simulates work by calling the Thread.Sleep method to sleep for two seconds.

This article is also a good read.

As Paul Turner answered Socket.Connected cannot be used in this situation. You need to poll connection every time to see if connection is still active. This is code I used:

bool SocketConnected(Socket s)
{
    bool part1 = s.Poll(1000, SelectMode.SelectRead);
    bool part2 = (s.Available == 0);
    if (part1 && part2)
        return false;
    else
        return true;
}

It works like this:

• s.Poll returns true if
  • connection is closed, reset, terminated or pending (meaning no active connection)
  • connection is active and there is data available for reading
• s.Available returns number of bytes available for reading
• if both are true:
  • there is no data available to read so connection is not active

 * The first line of any docblock is the summary.  Make them one short

     * The @param tag contains the data type, then the parameter's

     * description aids readability.
     *
     * When writing a phrase, do not capitalize and do not end with a
     * period:
     *   + the string to be tested
     *
     * When writing a phrase followed by a sentence, do not capitalize the
     * phrase, but end it with a period to distinguish it from the start
     * of the next sentence:
     *   + the string to be tested. Must use UTF-8 encoding.
     *
     * Return tags should contain the data type then a description of
     * the data returned.  The data type can be any of PHP's data types
     * (int, float, bool, string, array, object, resource, mixed)
     * and should contain the type primarily returned.  For example, if
     * a method returns an object when things work correctly but false
     * when an error happens, say 'object' rather than 'mixed.'  Use
     * 'void' if nothing is returned.
     *

Or, as an alternate, parse the resource ID with the following code:

  mComponentName.setBackgroundColor(getResources().getColor(android.R.color.transparent));

A web application's context path is the directory that contains the web application's WEB-INF directory. It can be thought of as the 'home' of the web app. Often, when writing web applications, it can be important to get the actual location of this directory in the file system, since this allows you to do things such as read from files or write to files.

This location can be obtained via the ServletContext object's getRealPath() method. This method can be passed a String parameter set to File.separator to get the path using the operating system's file separator ("/" for UNIX, "\" for Windows).

window.location.href = 'file://///fileserver/upload/Old_Upload/05_06_2019/THRESHOLD/BBH/Look/chrs/Delia';

Nothing Worked for me.

I personally use Underscore.js or Lodash for object and array manipulation:

myObject = _.omit(myObject, 'regex');

If what you want is the total number of records in the table appended to each row you can do something like

SELECT *
  FROM my_table
  CROSS JOIN (SELECT COUNT(*) AS COUNT_OF_RECS_IN_MY_TABLE
                FROM MY_TABLE)

In most of the cases, if you are unable to export the certificate as a PFX (including the private key) is because MMC/IIS cannot find/don't have access to the private key (used to generate the CSR). These are the steps I followed to fix this issue:

• Run MMC as Admin
  • Generate the CSR using MMC. Follow this instructions to make the certificate exportable.
• Once you get the certificate from the CA (crt + p7b), import them (Personal\Certificates, and Intermediate Certification Authority\Certificates)
• IMPORTANT: Right-click your new certificate (Personal\Certificates) All Tasks..Manage Private Key, and assign permissions to your account or Everyone (risky!). You can go back to previous permissions once you have finished.
• Now, right-click the certificate and select All Tasks..Export, and you should be able to export the certificate including the private key as a PFX file, and you can upload it to Azure!

Hope this helps!

Just send xml bytes directly:

#!/usr/bin/env python2
# -*- coding: utf-8 -*-
import requests

xml = """<?xml version='1.0' encoding='utf-8'?>
<a>?</a>"""
headers = {'Content-Type': 'application/xml'} # set what your server accepts
print requests.post('http://httpbin.org/post', data=xml, headers=headers).text

Output

{
  "origin": "x.x.x.x",
  "files": {},
  "form": {},
  "url": "http://httpbin.org/post",
  "args": {},

Here is a little code. It works (for me) at any subsequent html code change of the WebBrowser control. You may adapt it to your specific needs.

    static public void SetWebBrowserHtml(WebBrowser Browser, string HtmlText)
    {
        if (Browser != null)
        {
            if (string.IsNullOrWhiteSpace(HtmlText))
            {
                // Putting a div inside body forces control to use div instead of P (paragraph)
                // when the user presses the enter button
                HtmlText = 
                        @"<html>

                Browser.Navigate("about:blank");

                //Wait for document to finish loading

Well maybe a little late after 4 years haha... but I was looking for solution to do OBJECT to CSV, however most solutions here is actually for ARRAY to CSV...

After some tinkering, here is my solution to convert object into CSV, I think is pretty neat. Hope this would help someone else.

$resp = array();
foreach ($entries as $entry) {
    $row = array();
    foreach ($entry as $key => $value) {
        array_push($row, $value);
    }
    array_push($resp, implode(',', $row));
}
echo implode(PHP_EOL, $resp);

Note that for the $key => $value to work, your object's attributes must be public, the private ones will not get fetched.

The end result is that you get something like this:

blah,blah,blah
blah,blah,blah

When you use a blade echo {{ $data }} it will automatically escape the output. It can only escape strings. In your data $data->ac is an array and $data is an object, neither of which can be echoed as is. You need to be more specific of how the data should be outputted. What exactly that looks like entirely depends on what you're trying to accomplish. For example to display the link you would need to do {{ $data->ac[0][0]['url'] }} (not sure why you have two nested arrays but I'm just following your data structure).

@foreach($data->ac['0'] as $link)
    <a href="{{ $link['url'] }}">This is a link</a>
@endforeach

for (Map.Entry<String, ArrayList<String>> entry : test1.entrySet()) {
    String key = entry.getKey();
    ArrayList<String> value = entry.getValue();
    // now work with key and value...
}

By the way, you should really declare your variables as the interface type instead, such as Map<String, List<String>>.

There is no forumula, as street names and cities are essentially handed out randomly. The address needs to be looked up in a database. Alternatively, you can look up a zip code in a database for the region that the zip code is for.

You didn't mention a country, so I'm going to assume you just want addresses in the USA. There are numerous databases you can use, some free, some not.

You can also use the Google Maps API to have them look up an address in their database for you. That is probably the easiest solution, but requires your application to have a working internet connection at all times.

selecting Signature Version v1 and v2 both solved the problem for me....try it

Use some external app like sed:

<exec executable="sed" inputstring="${wersja}" outputproperty="wersjaDot">
  <arg value="s/_/./g"/>
</exec>
<echo>${wersjaDot}</echo>

If you run Windows get it googling for "gnuwin32 sed".

The command s/_/./g replaces every _ with . This script goes well under windows. Under linux arg may need quoting.

Just add the column names, yes you can use Null instead but is is a very bad idea to not use column names in any insert, ever.

RewriteEngine on
RewriteRule ^(.*)\.html$ $1.php%{QUERY_STRING} [L]

Put these two lines at the top of your .htaccess file. It will show .html in the URL for your .php pages.

RewriteEngine on
RewriteRule ^(.*)\.php$ $1.html%{QUERY_STRING} [L]

Use this for showing .php in URL for your .html pages.

There are two options here.

1. a hidden field within the form, or
2. Add it to the route values parameter in the begin form method.

Edit

@Html.Hidden("clubid", ViewBag.Club.id)

or

 @using(Html.BeginForm("action", "controller",
                       new { clubid = @Viewbag.Club.id }, FormMethod.Post, null)

XAML ListBox Scroller - Windows 10(UWP)

<Style TargetType="ListBox">
    <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Visible"/>
    <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Visible"/>
</Style>

There are no vertical lines in html that you can use but you can fake one by absolutely positioning a div outside of your container with a top:0; and bottom:0; style.

Try this:

CSS

.vr {
    width:10px;
    background-color:#000;
    position:absolute;
    top:0;
    bottom:0;
    left:150px;
}

HTML

<div class="vr">&nbsp;</div>

One of my SQL jobs had the same issue. It involved uploadaing data from one server to another. The error occurred because I was using sql Server Agent Service Account. I created a Credential using a UserId (that uses Window authentication) common to all servers. Then created a Proxy using this credential. Used the proxy in sql server job and it is running fine.

The difference relies in how the symbol is converted into its respective column type in query language.

with MySQL :string is mapped to VARCHAR(255)

• https://edgeguides.rubyonrails.org/active_record_migrations.html

:string |                   VARCHAR                | :limit => 1 to 255 (default = 255)  
:text   | TINYTEXT, TEXT, MEDIUMTEXT, or LONGTEXT2 | :limit => 1 to 4294967296 (default = 65536)

When should each be used?

As a general rule of thumb, use :string for short text input (username, email, password, titles, etc.) and use :text for longer expected input such as descriptions, comment content, etc.

        } else {
            $("#timeLeft").html(eval(timeLeft)- eval(1));
        }
    }, 1000);
});

Linux

In Linux, this information is available in the /proc file system. I'm not a big fan of the text file format used, as each Linux distribution seems to customize at least one important file. A quick look as the source to 'ps' reveals the mess.

But here is where to find the information you seek:

/proc/meminfo contains the majority of the system-wide information you seek. Here it looks like on my system; I think you are interested in MemTotal, MemFree, SwapTotal, and SwapFree:

For CPU utilization, you have to do a little work. Linux makes available overall CPU utilization since system start; this probably isn't what you are interested in. If you want to know what the CPU utilization was for the last second, or 10 seconds, then you need to query the information and calculate it yourself.

The information is available in /proc/stat, which is documented pretty well at http://www.linuxhowtos.org/System/procstat.htm; here is what it looks like on my 4-core box:

Anderson cxc #  more /proc/stat
cpu  2329889 0 2364567 1063530460 9034 9463 96111 0

First, you need to determine how many CPUs (or processors, or processing cores) are available in the system. To do this, count the number of 'cpuN' entries, where N starts at 0 and increments. Don't count the 'cpu' line, which is a combination of the cpuN lines. In my example, you can see cpu0 through cpu3, for a total of 4 processors. From now on, you can ignore cpu0..cpu3, and focus only on the 'cpu' line.

Next, you need to know that the fourth number in these lines is a measure of idle time, and thus the fourth number on the 'cpu' line is the total idle time for all processors since boot time. This time is measured in Linux "jiffies", which are 1/100 of a second each.

But you don't care about the total idle time; you care about the idle time in a given period, e.g., the last second. Do calculate that, you need to read this file twice, 1 second apart.Then you can do a diff of the fourth value of the line. For example, if you take a sample and get:

cpu  2330047 0 2365006 1063853632 9035 9463 96114 0

Then one second later you get this sample:

cpu  2330047 0 2365007 1063854028 9035 9463 96114 0

Subtract the two numbers, and you get a diff of 396, which means that your CPU had been idle for 3.96 seconds out of the last 1.00 second. The trick, of course, is that you need to divide by the number of processors. 3.96 / 4 = 0.99, and there is your idle percentage; 99% idle, and 1% busy.

In my code, I have a ring buffer of 360 entries, and I read this file every second. That lets me quickly calculate the CPU utilization for 1 second, 10 seconds, etc., all the way up to 1 hour.

For the process-specific information, you have to look in /proc/pid; if you don't care abut your pid, you can look in /proc/self.

CPU used by your process is available in /proc/self/stat. This is an odd-looking file consisting of a single line; for example:

19340 (whatever) S 19115 19115 3084 34816 19115 4202752 118200 607 0 0 770 384 2
 7 20 0 77 0 266764385 692477952 105074 4294967295 134512640 146462952 321468364
8 3214683328 4294960144 0 2147221247 268439552 1276 4294967295 0 0 17 0 0 0 0

The important data here are the 13th and 14th tokens (0 and 770 here). The 13th token is the number of jiffies that the process has executed in user mode, and the 14th is the number of jiffies that the process has executed in kernel mode. Add the two together, and you have its total CPU utilization.

Again, you will have to sample this file periodically, and calculate the diff, in order to determine the process's CPU usage over time.

Edit: remember that when you calculate your process's CPU utilization, you have to take into account 1) the number of threads in your process, and 2) the number of processors in the system. For example, if your single-threaded process is using only 25% of the CPU, that could be good or bad. Good on a single-processor system, but bad on a 4-processor system; this means that your process is running constantly, and using 100% of the CPU cycles available to it.

For the process-specific memory information, you ahve to look at /proc/self/status, which looks like this:

Name:   whatever
State:  S (sleeping)
Tgid:   19340

The entries that start with 'Vm' are the interesting ones:

• VmPeak is the maximum virtual memory space used by the process, in kB (1024 bytes).
• VmSize is the current virtual memory space used by the process, in kB. In my example, it's pretty large: 651,352 kB, or about 636 megabytes.
• VmRss is the amount of memory that have been mapped into the process' address space, or its resident set size. This is substantially smaller (420,296 kB, or about 410 megabytes). The difference: my program has mapped 636 MB via mmap(), but has only accessed 410 MB of it, and thus only 410 MB of pages have been assigned to it.

The only item I'm not sure about is Swapspace currently used by my process. I don't know if this is available.

You should use List<Person> or a HashSet<Person>.

Cache-Control: no-cache, no-store

These two header values can be combined to get the required effect on both IE and Firefox

@JulienD Best way is to break above process into two steps.

Step 1 : Lets say 'rawList' as your list that you want to add as parameters in prepared statement.

Create another list :

ArrayList<String> listWithQuotes = new ArrayList<String>();

for(String element : rawList){
    listWithQuotes.add("'"+element+"'");
}

Step 2 : Make 'listWithQuotes' comma separated.

String finalString = StringUtils.join(listWithQuotes.iterator(),",");

'finalString' will be string parameters with each element as single quoted and comma separated.

To elaborate slightly on @erikkallen's excellent answer, here is a function that allows all keyboard-based input types, including those introduced in HTML5:

$(document).unbind('keydown').bind('keydown', function (event) {
    var doPrevent = false;
    var INPUTTYPES = [
        "text", "password", "file", "date", "datetime", "datetime-local",
        "month", "week", "time", "email", "number", "range", "search", "tel",
        "url"];
    var TEXTRE = new RegExp("^" + INPUTTYPES.join("|") + "$", "i");
    if (event.keyCode === 8) {
        var d = event.srcElement || event.target;
        if ((d.tagName.toUpperCase() === 'INPUT' && d.type.match(TEXTRE)) ||
             d.tagName.toUpperCase() === 'TEXTAREA') {
            doPrevent = d.readOnly || d.disabled;
        } else {
            doPrevent = true;
        }
    }
    if (doPrevent) {
        event.preventDefault();
    }
});

You can't use transparency on background-images directly, but you can achieve this effect with something like this:

http://jsfiddle.net/m4TgL/

HTML:

<div class="container">
    <div class="content">//my blog post</div>
</div>?

CSS:

.container {  position: relative; }

.container:before {
    content: "";
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    z-index: 1;
    background-image: url('image.jpg');
   opacity: 0.5;
}

.content {
    position: relative; 
    z-index: 2;
}?

The easiest way is to populate your bean would be from a Reader object, this can be done in a single call:

BufferedReader reader = request.getReader();
Gson gson = new Gson();

MyBean myBean = gson.fromJson(reader, MyBean.class);

suppose you want to write a url to fetch some order, you can say

www.mydomain.com/order/123

where 123 is orderId.

So now the url you will use in spring mvc controller would look like

/order/{orderId}

Now order id can be declared a path variable

@RequestMapping(value = " /order/{orderId}", method=RequestMethod.GET)
public String getOrder(@PathVariable String orderId){
//fetch order
}

if you use url www.mydomain.com/order/123, then orderId variable will be populated by value 123 by spring

Also note that PathVariable differs from requestParam as pathVariable is part of URL. The same url using request param would look like www.mydomain.com/order?orderId=123

In addition to given answer, it's worth noting that compiler is not required to initialize constexpr variable at compile time, knowing that the difference between constexpr and static constexpr is that to use static constexpr you ensure the variable is initialized only once.

Following code demonstrates how constexpr variable is initialized multiple times (with same value though), while static constexpr is surely initialized only once.

In addition the code compares the advantage of constexpr against const in combination with static.

#include <iostream>
#include <string>
#include <cassert>
#include <sstream>

const short const_short = 0;
constexpr short constexpr_short = 0;

// print only last 3 address value numbers
const short addr_offset = 3;

// This function will print name, value and address for given parameter
void print_properties(std::string ref_name, const short* param, short offset)
{
    // determine initial size of strings
    std::string title = "value \\ address of ";
    const size_t ref_size = ref_name.size();
    const size_t title_size = title.size();
    assert(title_size > ref_size);

    // create title (resize)
    title.append(ref_name);
    title.append(" is ");
    title.append(title_size - ref_size, ' ');

    // extract last 'offset' values from address
    std::stringstream addr;
    addr << param;
    const std::string addr_str = addr.str();
    const size_t addr_size = addr_str.size();
    assert(addr_size - offset > 0);

    // print title / ref value / address at offset
    std::cout << title << *param << " " << addr_str.substr(addr_size - offset) << std::endl;
}

// here we test initialization of const variable (runtime)
void const_value(const short counter)
{
    static short temp = const_short;
    const short const_var = ++temp;
    print_properties("const", &const_var, addr_offset);

    if (counter)
        const_value(counter - 1);
}

// here we test initialization of static variable (runtime)
void static_value(const short counter)
{
    static short temp = const_short;
    static short static_var = ++temp;
    print_properties("static", &static_var, addr_offset);

    if (counter)
        static_value(counter - 1);
}

// here we test initialization of static const variable (runtime)
void static_const_value(const short counter)
{
    static short temp = const_short;
    static const short static_var = ++temp;
    print_properties("static const", &static_var, addr_offset);

    if (counter)
        static_const_value(counter - 1);
}

// here we test initialization of constexpr variable (compile time)
void constexpr_value(const short counter)
{
    constexpr short constexpr_var = constexpr_short;
    print_properties("constexpr", &constexpr_var, addr_offset);

    if (counter)
        constexpr_value(counter - 1);
}

// here we test initialization of static constexpr variable (compile time)
void static_constexpr_value(const short counter)
{
    static constexpr short static_constexpr_var = constexpr_short;
    print_properties("static constexpr", &static_constexpr_var, addr_offset);

    if (counter)
        static_constexpr_value(counter - 1);
}

// final test call this method from main()
void test_static_const()
{
    constexpr short counter = 2;

    const_value(counter);
    std::cout << std::endl;

    static_value(counter);
    std::cout << std::endl;

    static_const_value(counter);
    std::cout << std::endl;

    constexpr_value(counter);
    std::cout << std::endl;

    static_constexpr_value(counter);
    std::cout << std::endl;
}

Possible program output:

value \ address of const is               1 564
value \ address of const is               2 3D4
value \ address of const is               3 244

value \ address of static is              1 C58
value \ address of static is              1 C58
value \ address of static is              1 C58

value \ address of static const is        1 C64
value \ address of static const is        1 C64
value \ address of static const is        1 C64

value \ address of constexpr is           0 564
value \ address of constexpr is           0 3D4
value \ address of constexpr is           0 244

value \ address of static constexpr is    0 EA0
value \ address of static constexpr is    0 EA0
value \ address of static constexpr is    0 EA0

As you can see yourself constexpr is initilized multiple times (address is not the same) while static keyword ensures that initialization is performed only once.

Using the -u command-line switch works, but it is a little bit clumsy. It would mean that the program would potentially behave incorrectly if the user invoked the script without the -u option. I usually use a custom stdout, like this:

class flushfile:
  def __init__(self, f):
    self.f = f

  def write(self, x):
    self.f.write(x)
    self.f.flush()

import sys
sys.stdout = flushfile(sys.stdout)

... Now all your print calls (which use sys.stdout implicitly), will be automatically flushed.

A word of caution: “the w in bw does not stand for write but for wipeout!”

More from manuals:

:bd

Unload buffer [N] (default: current buffer) and delete it from the buffer list. If the buffer was changed, this fails, unless when [!] is specified, in which case changes are lost. The file remains unaffected.

If you know what you’re doing, you can also use :bw

:bw

Like |:bdelete|, but really delete the buffer.

If you must load the gif image from URL, you can always embed the gif in an image tag in a UIWebView.

Use PHP Document Object Model:

<?php
   $str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
   $DOM = new DOMDocument;
   $DOM->loadHTML($str);

   //get all H1
   $items = $DOM->getElementsByTagName('h1');

   //display all H1 text
   for ($i = 0; $i < $items->length; $i++)
        echo $items->item($i)->nodeValue . "<br/>";
?>

This outputs as:

 T1
 T2
 T3

[EDIT]: After OP Clarification:

If you want the content like Lorem ipsum. etc, you can directly use this regex:

<?php
   $str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
   echo preg_replace("#<h1.*?>.*?</h1>#", "", $str);
?>

this outputs:

Lorem ipsum.The quick red fox...... jumps over the lazy brown FROG

In my case I was developing an ASP.Net MVC5 web app and the certificate errors on my local dev machine (IISExpress certificate) started becoming a practical concern once I started working with service workers. Chrome simply wouldn't register my service worker because of the certificate error.

I did, however, notice that during my automated Selenium browser tests, Chrome seem to just "ignore" all these kinds of problems (e.g. the warning page about an insecure site), so I asked myself the question: How is Selenium starting Chrome for running its tests, and might it also solve the service worker problem?

Using Process Explorer on Windows, I was able to find out the command-line arguments with which Selenium is starting Chrome:

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-background-networking --disable-client-side-phishing-detection --disable-default-apps --disable-hang-monitor --disable-popup-blocking --disable-prompt-on-repost --disable-sync --disable-web-resources --enable-automation --enable-logging --force-fieldtrials=SiteIsolationExtensions/Control --ignore-certificate-errors --log-level=0 --metrics-recording-only --no-first-run --password-store=basic --remote-debugging-port=12207 --safebrowsing-disable-auto-update --test-type=webdriver --use-mock-keychain --user-data-dir="C:\Users\Sam\AppData\Local\Temp\some-non-existent-directory" data:,

There are a bunch of parameters here that I didn't end up doing necessity-testing for, but if I run Chrome this way, my service worker registers and works as expected.

The only one that does seem to make a difference is the --user-data-dir parameter, which to make things work can be set to a non-existent directory (things won't work if you don't provide the parameter).

Hope that helps someone else with a similar problem. I'm using Chrome 60.0.3112.90.

As you set application/x-www-form-urlencoded as content type so data sent must be like this format.

String urlParameters  = "param1=data1&param2=data2&param3=data3";

Sending part now is quite straightforward.

byte[] postData = urlParameters.getBytes( StandardCharsets.UTF_8 );
int postDataLength = postData.length;
String request = "<Url here>";
URL url = new URL( request );
HttpURLConnection conn= (HttpURLConnection) url.openConnection();           
conn.setDoOutput(true);
conn.setInstanceFollowRedirects(false);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
conn.setRequestProperty("charset", "utf-8");
conn.setRequestProperty("Content-Length", Integer.toString(postDataLength ));
conn.setUseCaches(false);
try(DataOutputStream wr = new DataOutputStream(conn.getOutputStream())) {
   wr.write( postData );
}

Or you can create a generic method to build key value pattern which is required for application/x-www-form-urlencoded.

private String getDataString(HashMap<String, String> params) throws UnsupportedEncodingException{
    StringBuilder result = new StringBuilder();
    boolean first = true;
    for(Map.Entry<String, String> entry : params.entrySet()){
        if (first)
            first = false;
        else
            result.append("&");    
        result.append(URLEncoder.encode(entry.getKey(), "UTF-8"));
        result.append("=");
        result.append(URLEncoder.encode(entry.getValue(), "UTF-8"));
    }    
    return result.toString();
}

hope this helps

select DeptName from DEPARTMENT inner join EMPLOYEE using (DeptId) where Salary>1000 group by DeptName having count(*)>2

You can use regular expressions like this:

SELECT * FROM pet WHERE name REGEXP 'Bob|Smith'; 

Use explicit injection. No other approach will allow you for instance to run tests in parallel in the same JVM.

Patterns that use anything classloader wide like static log binder or messing with environmental thinks like logback.XML are bust when it comes to testing.

Consider the parallelized tests I mention , or consider the case where you want to intercept logging of component A whose construction is hidden behind api B. This latter case is easy to deal with if you are using a dependency injected loggerfactory from the top, but not if you inject Logger as there no seam in this assembly at ILoggerFactory.getLogger.

And its not all about unit testing either. Sometimes we want integration tests to emit logging. Sometimes we don't. Someone's we want some of the integration testing logging to be selectively suppressed, eg for expected errors that would otherwise clutter the CI console and confuse. All easy if you inject ILoggerFactory from the top of your mainline (or whatever di framework you might use)

So...

Either inject a reporter as suggested or adopt a pattern of injecting the ILoggerFactory. By explicit ILoggerFactory injection rather than Logger you can support many access/intercept patterns and parallelization.

Is it possible to select an element if it contains a specific child element?

Unfortunately not yet.

The CSS2 and CSS3 selector specifications do not allow for any sort of parent selection.

A Note About Specification Changes

This is a disclaimer about the accuracy of this post from this point onward. Parent selectors in CSS have been discussed for many years. As no consensus has been found, changes keep happening. I will attempt to keep this answer up-to-date, however be aware that there may be inaccuracies due to changes in the specifications.

An older "Selectors Level 4 Working Draft" described a feature which was the ability to specify the "subject" of a selector. This feature has been dropped and will not be available for CSS implementations.

The subject was going to be the element in the selector chain that would have styles applied to it.

<p><span>lorem</span> ipsum dolor sit amet</p>
<p>consecteture edipsing elit</p>

This selector would style the span element

p span {
    color: red;
}

This selector would style the p element

!p span {
    color: red;
}

A more recent "Selectors Level 4 Editor’s Draft" includes "The Relational Pseudo-class: :has()"

:has() would allow an author to select an element based on its contents. My understanding is it was chosen to provide compatibility with jQuery's custom :has() pseudo-selector*.

In any event, continuing the example from above, to select the p element that contains a span one could use:

p:has(span) {
    color: red;
}

_{* This makes me wonder if jQuery had implemented selector subjects whether subjects would have remained in the specification.}

You don't need to run any docker commands as sudo when you're using boot2docker as every command passed into the boot2docker VM runs as root by default.

You're seeing the error when you're running as sudo because sudo doesn't have the DOCKER_HOST env set, only your user does.

You can confirm this by doing a:

$ env

Then a

$ sudo env

And looking for DOCKER_HOST in each output.

As for having a docker file that runs your script, something like this might work for you:

Dockerfile

FROM busybox

# Copy your script into the docker image
ADD /path/to/your/script.sh /usr/local/bin/script.sh

# Run your script
CMD /usr/local/bin/script.sh

Then you can run:

docker build -t your-image-name:your-tag .

This will build your docker image, which you can see by doing a:

docker images

Then, to run your container, you can do a:

docker run your-image-name:your-tag

This run command will start a container from the image you created with your Dockerfile and your build command and then it will finish once your script.sh has finished executing.

@ImportanceOfBeingErnest 's answer is good if you only want to change the linewidth inside the legend box. But I think it is a bit more complex since you have to copy the handles before changing legend linewidth. Besides, it can not change the legend label fontsize. The following two methods can not only change the linewidth but also the legend label text font size in a more concise way.

Method 1

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the individual lines inside legend and set line width
for line in leg.get_lines():
    line.set_linewidth(4)
# get label texts inside legend and set font size
for text in leg.get_texts():
    text.set_fontsize('x-large')

plt.savefig('leg_example')
plt.show()

Method 2

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the lines and texts inside legend box
leg_lines = leg.get_lines()
leg_texts = leg.get_texts()
# bulk-set the properties of all lines and texts
plt.setp(leg_lines, linewidth=4)
plt.setp(leg_texts, fontsize='x-large')
plt.savefig('leg_example')
plt.show()

The above two methods produce the same output image:

If is very simple, just kill the process..

A common problem is that node-gyp requires Python 2.x and if your system's python points to 3.x, it will fail to compile bson, without warning. You can fix this by setting a python global key in your npm config that points to the 2.x executable on your system. For example, on Arch Linux:

npm config -g set python "/usr/bin/python2"

I just hit this after doing a fresh install of DOCKER from the main docs. The problem for me was that immediately after the install, the service is not running.

These commands will help you to make sure docker is up and running for your run command to find it:

$ sudo service --status-all 
$ sudo service docker start
$ sudo service docker start

An improved version of @Thomas K's answer:

• Defining an assistant function is_any_thread_alive() according to this gist, which can terminates the main() automatically.

Example codes:

import threading

def job1():
    ...

def job2():
    ...

def is_any_thread_alive(threads):
    return True in [t.is_alive() for t in threads]

if __name__ == "__main__":
    ...
    t1 = threading.Thread(target=job1,daemon=True)
    t2 = threading.Thread(target=job2,daemon=True)
    t1.start()
    t2.start()

    while is_any_thread_alive([t1,t2]):
        time.sleep(0)

I use the lattice package for almost everything I plot in R and it has a corresponing plot to persp called wireframe. Let data be the way Sven defined it.

wireframe(z ~ x * y, data=data)

Or how about this (modification of fig 6.3 in Deepanyan Sarkar's book):

p <- wireframe(z ~ x * y, data=data)
npanel <- c(4, 2)
rotx <- c(-50, -80)
rotz <- seq(30, 300, length = npanel[1]+1)
update(p[rep(1, prod(npanel))], layout = npanel,
    panel = function(..., screen) {
        panel.wireframe(..., screen = list(z = rotz[current.column()],
                                           x = rotx[current.row()]))
    })

Update: Plotting surfaces with OpenGL

Since this post continues to draw attention I want to add the OpenGL way to make 3-d plots too (as suggested by @tucson below). First we need to reformat the dataset from xyz-tripplets to axis vectors x and y and a matrix z.

x <- 1:5/10
y <- 1:5
z <- x %o% y
z <- z + .2*z*runif(25) - .1*z

library(rgl)
persp3d(x, y, z, col="skyblue")

This image can be freely rotated and scaled using the mouse, or modified with additional commands, and when you are happy with it you save it using rgl.snapshot.

rgl.snapshot("myplot.png")

Another helpful but simple solution might be restarting your computer after doing the download if Python is in the PATH variable. This has been a mistake I usually make when downloading Python onto a new machine.

After restarting my machine then Windows will often recognize Python in the PATH variable.

updatepanel issue.

My issue was due to the updatepanel placement. I had the entire modal in the updatepanel. If you declare the modal outside the updatepanel and just have say, the modal body, in the update panel, then the $('#myModalID').modal('hide'); worked.

A slight variation...

new File('/path/to/file').eachLine { line ->
  println line
}

value = value.setScale(2, RoundingMode.CEILING)

start "Chrome" "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Profile 2"

start "webpage name" "http://someurl.com/"

start "Chrome" "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Profile 3"

start "webpage name" "http://someurl.com/"

Approach 1

While converting a gray scale image to a binary image, we usually use cv2.threshold() and set a threshold value manually. Sometimes to get a decent result we opt for Otsu's binarization.

I have a small hack I came across while reading some blog posts.

1. Convert your color (RGB) image to gray scale.
2. Obtain the median of the gray scale image.
3. Choose a threshold value either 33% above the median

Why 33%?

This is because 33% works for most of the images/data-set.

You can also work out the same approach by replacing median with the mean.

Approach 2

Another approach would be to take an x number of standard deviations (std) from the mean, either on the positive or negative side; and set a threshold. So it could be one of the following:

• th1 = mean - (x * std)
• th2 = mean + (x * std)

Note: Before applying threshold it is advisable to enhance the contrast of the gray scale image locally (See CLAHE).

short answer, partial gives default values to the parameters of a function that would otherwise not have default values.

from functools import partial

def foo(a,b):
    return a+b

bar = partial(foo, a=1) # equivalent to: foo(a=1, b)
bar(b=10)
#11 = 1+10
bar(a=101, b=10)
#111=101+10

You can also try using apply with get method of dictionary, seems to be little faster than replace:

data['sex'] = data['sex'].apply({1:'Male', 0:'Female'}.get)

Testing with timeit:

%%timeit
data['sex'].replace([0,1],['Female','Male'],inplace=True)

Result:

The slowest run took 5.83 times longer than the fastest. This could mean that an intermediate result is being cached.
1000 loops, best of 3: 510 µs per loop

Using apply:

%%timeit
data['sex'] = data['sex'].apply({1:'Male', 0:'Female'}.get)

Result:

The slowest run took 5.92 times longer than the fastest. This could mean that an intermediate result is being cached.
1000 loops, best of 3: 331 µs per loop

Note: apply with dictionary should be used if all the possible values of the columns in the dataframe are defined in the dictionary else, it will have empty for those not defined in dictionary.

This is a possible generic implementation using a bit of reflection (pseudo-code, don't have VS now):

public class DtoMapper<DtoType>
{
    Dictionary<string,PropertyInfo> properties;

    public DtoMapper()
    {
        // Cache property infos
        var t = typeof(DtoType);
        properties = t.GetProperties().ToDictionary(p => p.Name, p => p);
     }

    public DtoType Map(Dto dto)
    {
        var instance = Activator.CreateInstance(typeOf(DtoType));

        foreach(var p in properties)
        {
            p.SetProperty(
                instance, 
                Convert.Type(
                    p.PropertyType, 
                    dto.Items[Array.IndexOf(dto.ItemsNames, p.Name)]);

            return instance;
        }
    }

Usage:

var mapper = new DtoMapper<Model>();
var modelInstance = mapper.Map(dto);

This will be slow when you create the mapper instance but much faster later.

vim /etc/default/locale

add to it:

LC_ALL="en_US.UTF-8"

I had to merge some of those good answers here! This works for me:

git remote set-url origin 'https://bitbucket.org/teamName/repo.git'

In the end, it will always prompt anyone who wants to pull from it

Static array :Efficiency. No dynamic allocation or deallocation is required.

Arrays declared in C, C++ in function including static modifier are static. Example: static int foo[5];

SSH doesn't use the : syntax when specifying a port. The easiest way to do this is to edit your ~/.ssh/config file and add:

Host git.host.de
  Port 4019

Then specify just git.host.de without a port number.

I got the same error because I had accidentally used <div> instead of <canvas> as the element on which I attempt to call getContext.

Try setting 'clientCredentialType' to 'Windows' instead of 'Ntlm'.

I think that this is what the server is expecting - i.e. when it says the server expects "Negotiate,NTLM", that actually means Windows Auth, where it will try to use Kerberos if available, or fall back to NTLM if not (hence the 'negotiate')

I'm basing this on somewhat reading between the lines of: Selecting a Credential Type

Inspired by the previous posters I wanted to share my solution. It works with a scale factor which is applied to the previous font size to make it fit the available space. In addition to prevent unexpected behaviour of TextViews onDraw method, it simply draws the text on its own.

public class FontFitTextView extends TextView {

    // How much of the available space should be used in percent.
    private static final float MARGINHEIGHT = 0.8f;
    private static final float MARGINWIDTH = 0.8f;

    private Paint paint;
    private int viewWidth;
    private int viewHeight;
    private float textHeight;
    private float textWidth;

    public FontFitTextView(Context c) {
        this(c, null);
    }

    public FontFitTextView(Context c, AttributeSet attrs) {
        super(c, attrs);
        initComponent();
    }

    // Default constructor override
    public FontFitTextView(Context c, AttributeSet attrs, int defStyle) {
        super(c, attrs, defStyle);
        initComponent();
    }

    private void initComponent() {
        paint = new Paint();
        paint.setTextSize(30);
        paint.setTextAlign(Align.CENTER);
        paint.setAntiAlias(true);
    }

    public void setFontColor(int c) {
        paint.setColor(c);
    }

    private void calcTextSize(String s, Canvas c) {

        float availableHeight = viewHeight;
        float availableWidth = viewWidth;

        // This value scales the old font up or down to match the available
        // space.
        float scale = 1.0f;

        // Rectangle for measuring the text dimensions
        Rect rect = new Rect();
        float oldFontSize = paint.getTextSize();

        // Calculate the space used with old font size
        paint.getTextBounds(s, 0, s.length(), rect);
        textWidth = rect.width();
        textHeight = rect.height();

        // find scale-value to fit the text horizontally
        float scaleWidth = 1f;
        if (textWidth > 0.0f) {
            scaleWidth = (availableWidth) / textWidth * MARGINWIDTH;
        }

        // find scale-value to fit the text vertically
        float scaleHeight = 1f;
        if (textHeight > 0.0f) {
            scaleHeight = (availableHeight) / textHeight * MARGINHEIGHT;
        }

        // We are always limited by the smaller one
        if (scaleWidth < scaleHeight) {
            scale = scaleWidth;
        } else {
            scale = scaleHeight;
        }

        // We apply the scale to the old font size to make it bigger or smaller
        float newFontSize = (oldFontSize * scale);
        paint.setTextSize(newFontSize);
    }

    /**
     * Calculates the origin on the Y-Axis (width) for the text in this view.
     * 
     * @return
     */
    private float calcStartDrawingPosX() {
        float left = getMeasuredWidth();
        float centerY = left - (viewWidth / 2);
        return centerY;
    }

    /**
     * Calculates the origin on the Y-Axis (height) for the text in this view.
     * 
     * @return
     */
    private float calcStartDrawingPosY() {
        float bottom = getMeasuredHeight();
        // The paint only centers horizontally, origin on the Y-Axis stays at
        // the bottom, thus we have to lift the origin additionally by the
        // height of the font.
        float centerX = bottom - (viewHeight / 2) + (textHeight / 2);
        return centerX;
    }

    @Override
    protected void onDraw(Canvas canvas) {
        String text = getText().toString();
        if (text.length() > 0) {
            calcTextSize(text, canvas);
            canvas.drawText(text, calcStartDrawingPosX(),
                    calcStartDrawingPosY(), paint);
        }
    };

    @Override
    protected void onSizeChanged(int w, int h, int oldw, int oldh) {
        viewWidth = w;
        viewHeight = h;
        super.onSizeChanged(w, h, oldw, oldh);
    }
}

There are two ways to set this up. If you have an SID, use this (older) format:

jdbc:oracle:thin:@[HOST][:PORT]:SID

If you have an Oracle service name, use this (newer) format:

jdbc:oracle:thin:@//[HOST][:PORT]/SERVICE

The call to getConnection() is correct.

Also, as duffymo said, make sure the actual driver code is present by including ojdbc6.jar in the classpath, where the number corresponds to the Java version you're using.

select * from left table where key field not in (select key field from right table)

While size(A,2) is correct, I find it's much more readable to first define

rows = @(x) size(x,1); 
cols = @(x) size(x,2);

and then use, for example, like this:

howManyColumns_in_A = cols(A)
howManyRows_in_A    = rows(A)

It might appear as a small saving, but size(.., 1) and size(.., 2) must be some of the most commonly used functions, and they are not optimally readable as-is.

Add Validate Connection=true to your connection string.

Look at this blog to find more about.

DETAILS: After OracleConnection.Close() the real database connection does not terminate. The connection object is put back in connection pool. The use of connection pool is implicit by ODP.NET. If you create a new connection you get one of the pool. If this connection is "yet open" the OracleConnection.Open() method does not really creates a new connection. If the real connection is broken (for any reason) you get a failure on first select, update, insert or delete.

With Validate Connection the real connection is validated in Open() method.

I solved this issue by accessing my fragments directly through the FragmentManager instead of via the FragmentPagerAdapter like so. First I need to figure out the tag of the fragment auto generated by the FragmentPagerAdapter...

private String getFragmentTag(int pos){
    return "android:switcher:"+R.id.viewpager+":"+pos;
}

Then I simply get a reference to that fragment and do what I need like so...

Fragment f = this.getSupportFragmentManager().findFragmentByTag(getFragmentTag(1));
((MyFragmentInterface) f).update(id, name);
viewPager.setCurrentItem(1, true);

Inside my fragments I set the setRetainInstance(false); so that I can manually add values to the savedInstanceState bundle.

@Override
public void onSaveInstanceState(Bundle outState) {
    if(this.my !=null)
        outState.putInt("myId", this.my.getId());

    super.onSaveInstanceState(outState);
}

and then in the OnCreate i grab that key and restore the state of the fragment as necessary. An easy solution which was hard (for me at least) to figure out.

You're using S_ISREG() and S_ISDIR() correctly, you're just using them on the wrong thing.

In your while((dit = readdir(dip)) != NULL) loop in main, you're calling stat on currentPath over and over again without changing currentPath:

if(stat(currentPath, &statbuf) == -1) {
    perror("stat");
    return errno;
}

Shouldn't you be appending a slash and dit->d_name to currentPath to get the full path to the file that you want to stat? Methinks that similar changes to your other stat calls are also needed.

I installed Postgresql92 using the RedHat / CentOS repository on PG's downloads site http://www.postgresql.org/download/linux/redhat/

To get pg_config, I had to add /usr/pgsql-9.2/bin to PATH.

How about

map(list, zip(*l))
--> [[1, 4, 7], [2, 5, 8], [3, 6, 9]]

For python 3.x users can use

list(map(list, zip(*l))) # short circuits at shortest nested list if table is jagged
list(map(list, itertools.zip_longest(*l, fillvalue=None))) # discards no data if jagged and fills short nested lists with None

Explanation:

There are two things we need to know to understand what's going on:

1. The signature of zip: zip(*iterables) This means zip expects an arbitrary number of arguments each of which must be iterable. E.g. zip([1, 2], [3, 4], [5, 6]).
2. Unpacked argument lists: Given a sequence of arguments args, f(*args) will call f such that each element in args is a separate positional argument of f.
3. itertools.zip_longest does not discard any data if the number of elements of the nested lists are not the same (homogenous), and instead fills in the shorter nested lists then zips them up.

Coming back to the input from the question l = [[1, 2, 3], [4, 5, 6], [7, 8, 9]], zip(*l) would be equivalent to zip([1, 2, 3], [4, 5, 6], [7, 8, 9]). The rest is just making sure the result is a list of lists instead of a list of tuples.

What about detached or unrelated shells and code [args] support?

While other answers talk about how to configure and use the VScode integrated WSL bash terminal support, they don't solve the problem of "detached shells": shells which were not launched from within VScode, or which somehow get "disconnected" from the VScode server instance associated with the IDE.

Such shells can give errors like:

Command is only available in WSL or inside a Visual Studio Code terminal.

or...

Unable to connect to VS Code server. Error in request

Here's a script which makes it easy to solve this problem.

I use this daily to connect shells in a tmux session with a specific VScode server instance, or to fix an integrated shell that's become detached from its hosting IDE.

#!/bin/bash
# codesrv-connect
#
#  Purpose:
#     Copies the vscode connection environment from one shell to another, so that you can use the
#     vscode integrated terminal's "code [args]" command to communicate with that instance of vscode
#     from an unrelated shell.
#
#  Usage:
#    1.  Open an integrated terminal in vscode, and run codesrv-connect
#    2.  In the target shell, cd to the same directory and run
#       ". .codesrv-connect", or follow the instruction printed by codesrv-connect.
#
#  Setup:
#    Put "codesrv-connect somewhere on your PATH (e.g. ~/bin)"
#
#  Cleanup:
#    - Delete abandoned .codesrv-connect files when their vscode sessions die.
#    - Do not add .codesrv-connect files to git repositories.
#
#  Notes:
#     The VSCODE_IPC_HOOK_CLI environment variable points to a socket which is rather volatile, while the long path for the 'code' alias is more stable: vscode doesn't change the latter even across a "code -r ." reload.  But the former is easily detached and so you need a fresh value if that happens.  This is what codesrv-connect does: it captures the value of these two and writes them to .codesrv-connect in the current dir.

The answer is in the documentation for bindParam:

Unlike PDOStatement::bindValue(), the variable is bound as a reference and will only be evaluated at the time that PDOStatement::execute() is called.

And execute

call PDOStatement::bindParam() to bind PHP variables to the parameter markers: bound variables pass their value as input and receive the output value, if any, of their associated parameter markers

Example:

$value = 'foo';
$s = $dbh->prepare('SELECT name FROM bar WHERE baz = :baz');
$s->bindParam(':baz', $value); // use bindParam to bind the variable
$value = 'foobarbaz';
$s->execute(); // executed with WHERE baz = 'foobarbaz'

or

$value = 'foo';
$s = $dbh->prepare('SELECT name FROM bar WHERE baz = :baz');
$s->bindValue(':baz', $value); // use bindValue to bind the variable's value
$value = 'foobarbaz';
$s->execute(); // executed with WHERE baz = 'foo'

If you want to make it controller specific, you can use:

res.setHeader('X-Frame-Options', 'ALLOWALL');
res.setHeader('Access-Control-Allow-Origin', '*');
res.setHeader('Access-Control-Allow-Methods', 'POST, GET');
res.setHeader('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept');

Please note that this will also allow iframes.

Just replace and with , and you're done:

try:
    with open('a', 'w') as a, open('b', 'w') as b:
        do_something()
except IOError as e:
    print 'Operation failed: %s' % e.strerror

If you have your dates in DateTime variables, they don't have a format.

You can use the Date property to return a DateTime value with the time portion set to midnight. So, if you have:

DateTime dt1 = DateTime.Parse("07/12/2011");
DateTime dt2 = DateTime.Now;

if(dt1.Date > dt2.Date)
{
     //It's a later date
}
else
{
     //It's an earlier or equal date
}

And what about:

if ($('#dataTable[data-timer]').length > 0) {
    // logic here
}

Or a nested List (okay, the OP was for a single column and this is for multiple columns..):

        //Base list is a list of fields, ie a data record
        //Enclosing list is then a list of those records, ie the Result set
        List<List<String>> ResultSet = new List<List<String>>();

        using (SqlConnection connection =
            new SqlConnection(connectionString))
        {
            // Create the Command and Parameter objects.
            SqlCommand command = new SqlCommand(qString, connection);

            // Create and execute the DataReader..
            connection.Open();
            SqlDataReader reader = command.ExecuteReader();
            while (reader.Read())
            {
                var rec = new List<string>();
                for (int i = 0; i <= reader.FieldCount-1; i++) //The mathematical formula for reading the next fields must be <=
                {                      
                    rec.Add(reader.GetString(i));
                }
                ResultSet.Add(rec);

            }
        }

You don't want to stretch the span in height?
You have the possiblity to affect one or more flex-items to don't stretch the full height of the container.

To affect all flex-items of the container, choose this:
You have to set align-items: flex-start; to div and all flex-items of this container get the height of their content.

div {_x000D_
  align-items: flex-start;_x000D_
  background: tan;_x000D_
  display: flex;_x000D_
  height: 200px;_x000D_
}_x000D_
span {_x000D_
  background: red;_x000D_
}

<div>_x000D_
  <span>This is some text.</span>_x000D_
</div>

To affect only a single flex-item, choose this:
If you want to unstretch a single flex-item on the container, you have to set align-self: flex-start; to this flex-item. All other flex-items of the container aren't affected.

div {_x000D_
  display: flex;_x000D_
  height: 200px;_x000D_
  background: tan;_x000D_
}_x000D_
span.only {_x000D_
  background: red;_x000D_
  align-self:flex-start;_x000D_
}_x000D_
span {_x000D_
    background:green;_x000D_
}

<div>_x000D_
  <span class="only">This is some text.</span>_x000D_
  <span>This is more text.</span>_x000D_
</div>

Why is this happening to the span?
The default value of the property align-items is stretch. This is the reason why the span fill the height of the div.

Difference between baseline and flex-start?
If you have some text on the flex-items, with different font-sizes, you can use the baseline of the first line to place the flex-item vertically. A flex-item with a smaller font-size have some space between the container and itself at top. With flex-start the flex-item will be set to the top of the container (without space).

div {_x000D_
  align-items: baseline;_x000D_
  background: tan;_x000D_
  display: flex;_x000D_
  height: 200px;_x000D_
}_x000D_
span {_x000D_
  background: red;_x000D_
}_x000D_
span.fontsize {_x000D_
  font-size:2em;_x000D_
}

<div>_x000D_
  <span class="fontsize">This is some text.</span>_x000D_
  <span>This is more text.</span>_x000D_
</div>

You can find more information about the difference between baseline and flex-start here:
What's the difference between flex-start and baseline?

The correct answer is, that, because the '%'-sign is part of your search expression, it should be part of your VALUE, so whereever you SET @LastName (be it from a programming language or from TSQL) you should set it to '%' + [userinput] + '%'

or, in your example:

DECLARE @LastName varchar(max)
SET @LastName = 'ning'
SELECT Employee WHERE LastName LIKE '%' + @LastName + '%'

... And here is the rounding way which doesn't truncate. Hurried to look it up in the Java API Manual:

double d = 1234.56;
long x = Math.round(d); //1235

Maybe a little late, but using different drivers altogether is overkill for a case of user error:

db.dbConnect("jdbc:sqlserver://localhost:1433/muff", "user", "pw" );

should be either one of these:

db.dbConnect("jdbc:sqlserver://localhost\muff", "user", "pw" );

(using named pipe) or:

db.dbConnect("jdbc:sqlserver://localhost:1433", "user", "pw" );

using port number directly; you can leave out 1433 because it's the default port, leaving:

db.dbConnect("jdbc:sqlserver://localhost", "user", "pw" );

Seems you are using outdated version of django.. Simply update django and try again.. Following command will update your django version..

pip install --upgrade django

BLOB stores binary data which are more than 2 GB. Max size for BLOB is 4 GB. Binary data means unstructured data i.e images audio files vedio files digital signature

Text is used to store large string.

Array.from({length:5}, i => 1) // [1, 1, 1, 1, 1]

or create array with increasing value

Array.from({length:5}, (e, i)=>i) // [0, 1, 2, 3, 4]

I suspect that the problem is that the path is incorrect. Try this:

UserInput.prompt("Enter name of file to delete");
String name = UserInput.readString();
File file = new File("\\Files\\" + name + ".txt");
if (file.exists()) {
    file.delete();
} else {
    System.err.println(
        "I cannot find '" + file + "' ('" + file.getAbsolutePath() + "')");
}

This code will open and read lines of complete text file That variable "ReadedData" Holds the text line in memory

Open "C:\satheesh\myfile\Hello.txt" For Input As #1

do until EOF(1)   

       Input #1, ReadedData
loop**

static byte[] SliceMe(byte[] source, int length)
{
    byte[] destfoo = new byte[length];
    Array.Copy(source, 0, destfoo, 0, length);
    return destfoo;
}

//

var myslice = SliceMe(sourcearray,41);

Using CSS Grid

HTML

<div class="container">
    <i class="fab fa-5x fa-file"></i>
    <span>text</span>
</div>

CSS

.container {
  display: grid;
  grid-template-columns: 1fr auto;
  align-items: center;
}

Working example

actually @bazzlebrush 's answer and @filoxo 's comment helped me a lot.

I needed to find the elements where the class could be "zA yO" OR "zA zE"

Using jquery I first select the parent of the desired elements:

(a div with class starting with 'abc' and style != 'display:none')

var tom = $('div[class^="abc"][style!="display: none;"]')[0];                   

then the desired children of that element:

var ax = tom.querySelectorAll('.zA.yO, .zA.zE');

works perfectly! note you don't have to do document.querySelector you can as above pass in a pre-selected object.

What is the difference?

From the documentation:

- (Boolean) instance_of?(class)

Returns true if obj is an instance of the given class.

and:

- (Boolean) is_a?(class)
- (Boolean) kind_of?(class)

Returns true if class is the class of obj, or if class is one of the superclasses of obj or modules included in obj.

If that is unclear, it would be nice to know what exactly is unclear, so that the documentation can be improved.

When should I use which?

Never. Use polymorphism instead.

Why are there so many of them?

I wouldn't call two "many". There are two of them, because they do two different things.

The declarative and simpler solution would be :

yourMutableMap.replaceAll((key, val) -> return_value_of_bi_your_function); Nb. be aware your modifying your map state. So this may not be what you want.

Cheers to : http://www.deadcoderising.com/2017-02-14-java-8-declarative-ways-of-modifying-a-map-using-compute-merge-and-replace/

mm stands for "minutes". Use MM instead:

SimpleDateFormat sdf1 = new SimpleDateFormat("dd-MM-yyyy");

You might want to use Scanner to parse through and find the specific sections you want to modify. There's also Split and StringTokenizer that may work, but at the level you're working at Scanner might be what's needed.

Here's some additional info on what the difference is between them: Scanner vs. StringTokenizer vs. String.Split

Just another viewpoint. Performing an "or" in Prolog can also be done with the "disjunct" operator or semi-colon:

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

For a fuller explanation:

Predicate control in Prolog

I have found the above answer to be the best solution, but I don't like the leading space before the percent sign. I have seen somewhat complicated solutions, but I just use this Replace addition to the answer above instead of using other rounding solutions.

String.Format("Value: {0:P2}.", 0.8526).Replace(" %","%") // formats as 85.26% (varies by culture)

They're simply different schemes for representing Unicode characters.

Both are variable-length - UTF-16 uses 2 bytes for all characters in the basic multilingual plane (BMP) which contains most characters in common use.

UTF-8 uses between 1 and 3 bytes for characters in the BMP, up to 4 for characters in the current Unicode range of U+0000 to U+1FFFFF, and is extensible up to U+7FFFFFFF if that ever becomes necessary... but notably all ASCII characters are represented in a single byte each.

For the purposes of a message digest it won't matter which of these you pick, so long as everyone who tries to recreate the digest uses the same option.

See this page for more about UTF-8 and Unicode.

(Note that all Java characters are UTF-16 code points within the BMP; to represent characters above U+FFFF you need to use surrogate pairs in Java.)

You can use the JSON stringify method.

JSON.stringify({x: 5, y: 6}); // '{"x":5,"y":6}' or '{"y":6,"x":5}'

There is pretty good support for this across the board when it comes to browsers, as shown on http://caniuse.com/#search=JSON. You will note, however, that versions of IE earlier than 8 do not support this functionality natively.

If you wish to cater to those users as well you will need a shim. Douglas Crockford has provided his own JSON Parser on github.

Here is a suggestion, using TimeUnit, to obtain each time part and format them.

private static String formatDuration(long duration) {
    long hours = TimeUnit.MILLISECONDS.toHours(duration);
    long minutes = TimeUnit.MILLISECONDS.toMinutes(duration) % 60;
    long seconds = TimeUnit.MILLISECONDS.toSeconds(duration) % 60;
    long milliseconds = duration % 1000;
    return String.format("%02d:%02d:%02d,%03d", hours, minutes, seconds, milliseconds);
}

SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss,SSS");
Date startTime = sdf.parse("01:00:22,427");
Date now = sdf.parse("02:06:38,355");
long duration = now.getTime() - startTime.getTime();
System.out.println(formatDuration(duration));

The result is: 01:06:15,928

An MSI is a Windows Installer database. Windows Installer (a service installed with Windows) uses this to install software on your system (i.e. copy files, set registry values, etc...).

A setup.exe may either be a bootstrapper or a non-msi installer. A non-msi installer will extract the installation resources from itself and manage their installation directly. A bootstrapper will contain an MSI instead of individual files. In this case, the setup.exe will call Windows Installer to install the MSI.

Some reasons you might want to use a setup.exe:

• Windows Installer only allows one MSI to be installing at a time. This means that it is difficult to have an MSI install other MSIs (e.g. dependencies like the .NET framework or C++ runtime). Since a setup.exe is not an MSI, it can be used to install several MSIs in sequence.
• You might want more precise control over how the installation is managed. An MSI has very specific rules about how it manages the installations, including installing, upgrading, and uninstalling. A setup.exe gives complete control over the software configuration process. This should only be done if you really need the extra control since it is a lot of work, and it can be tricky to get it right.

This article suggests the following properties of the browser's navigator object:

• navigator.language (Netscape - Browser Localization)
• navigator.browserLanguage (IE-Specific - Browser Localized Language)
• navigator.systemLanguage (IE-Specific - Windows OS - Localized Language)
• navigator.userLanguage

Roll these into a javascript function and you should be able to guess the right language, in most circumstances. Be sure to degrade gracefully, so have a div containing your language choice links, so that if there is no javascript or the method doesn't work, the user can still decide. If it does work, just hide the div.

The only problem with doing this on the client side is that either you serve up all the languages to the client, or you have to wait until the script has run and detected the language before requesting the right version. Perhaps serving up the most popular language version as a default would irritate the fewest people.

Edit: I'd second Ivan's cookie suggestion, but make sure the user can always change the language later; not everyone prefers the language their browser defaults to.

I'll jump in with the notorious "Do you really want to do that" answer.

It seems like your focus is on playing with Java and seeing what it can do. However, if you want to actually develop a web app, you should be aware that, although Java is used in web applications (and in serious ones), there are other technology options which might be more adequate.

Personally, I like (and use) Java for powerful, portable backend services on a server. I've never tried building websites with it, because it never seemed the most obvious ting to do. After growing tired of PHP (which I have been using for years), I lately fell in love with Django, a Python-based web framework.

The Ruby on Rails people have a number of very funny videos on youtube comparing different web technologies to RoR. Of course, these are obviously exaggerated and maybe slightly biased, but I'd say there's more than one grain of truth in each of them. The one about Java is here. ;-)

You also need to annotate the method with @JavascriptInterface if your targetSdkVersion is >= 17 - because there is new security requirements in SDK 17, i.e. all javascript methods must be annotated with @JavascriptInterface. Otherwise you will see error like: Uncaught TypeError: Object [object Object] has no method 'processHTML' at null:1

Based in the answer of @G M and paying attention to the @John La Rooy's warning, I was able to append a new row opening the file in 'a'mode.

Even in windows, in order to avoid the newline problem, you must declare it as newline=''.

Now you can open the file in 'a'mode (without the b).

import csv

with open(r'names.csv', 'a', newline='') as csvfile:
    fieldnames = ['This','aNew']
    writer = csv.DictWriter(csvfile, fieldnames=fieldnames)

    writer.writerow({'This':'is', 'aNew':'Row'})

I didn't try with the regular writer (without the Dict), but I think that it'll be ok too.

The syntax is

pid_t waitpid(pid_t pid, int *statusPtr, int options);

1.where pid is the process of the child it should wait.

2.statusPtr is a pointer to the location where status information for the terminating process is to be stored.

3.specifies optional actions for the waitpid function. Either of the following option flags may be specified, or they can be combined with a bitwise inclusive OR operator:

WNOHANG WUNTRACED WCONTINUED

If successful, waitpid returns the process ID of the terminated process whose status was reported. If unsuccessful, a -1 is returned.

benifits over wait

1.Waitpid can used when you have more than one child for the process and you want to wait for particular child to get its execution done before parent resumes

2.waitpid supports job control

3.it supports non blocking of the parent process

// using exec

function rCopy($directory, $destination)
{

    $command = sprintf('cp -r %s/* %s', $directory, $destination);

    exec($command);

}

Generally, this keyword is used inside a class, generally with in the member functions to access non-static members of a class(variables or functions) for the current object.

1. this keyword should be preceded with a $ symbol.
2. In case of this operator, we use the -> symbol.
3. Whereas, $this will refer the member variables and function for a particular instance.

Let's take an example to understand the usage of $this.

<?php
class Hero {
    // first name of hero
    private $name;
    
    // public function to set value for name (setter method)
    public function setName($name) {
        $this->name = $name;
    }
    
    // public function to get value of name (getter method)
    public function getName() {
        return $this->name;
    }
}

// creating class object
$stark = new Hero();

// calling the public function to set fname
$stark->setName("IRON MAN");

// getting the value of the name variable
echo "I Am " . $stark->getName();
?>

OUTPUT: I am IRON MAN

NOTE: A static variable acts as a global variable and is shared among all the objects of the class. A non-static variables are specific to instance object in which they are created.

If you want to add magic comments on all the source files of a project easily, you can use the magic_encoding gem

sudo gem install magic_encoding

then just call magic_encoding in the terminal from the root of your app.

Use the put method: https://developer.android.com/reference/org/json/JSONObject.html

JSONObject person =  jsonArray.getJSONObject(0).getJSONObject("person");
person.put("name", "Sammie");

#Edit (add explanation :) ) say you have an array you want to update your existing firestore document field with. You can use set(yourData, {merge: true} ) passing setOptions(second param in set function) with {merge: true} is must in order to merge the changes instead of overwriting. here is what the official documentation says about it

An options object that configures the behavior of set() calls in DocumentReference, WriteBatch, and Transaction. These calls can be configured to perform granular merges instead of overwriting the target documents in their entirety by providing a SetOptions with merge: true.

you can use this

const yourNewArray = [{who: "[email protected]", when:timestamp}
{who: "[email protected]", when:timestamp}]    


collectionRef.doc(docId).set(
  {
    proprietary: "jhon",
    sharedWith: firebase.firestore.FieldValue.arrayUnion(...yourNewArray),
  },
  { merge: true },
);

hope this helps :)

In my case, it was something else. One day earlier I tried to install wordpress using bitnam of xampp, but I was not successfull. When I saw the error log, there was an error :

httpd.exe: Syntax error on line 560 of C:/xampp/apache/conf/httpd.conf: Could not open configuration file C:/xampp/apps/wordpress/conf/httpd-prefix.conf: The system cannot find the path specified.

I opened the httpd.conf and found this line:

Include "C:/xampp/apps/wordpress/conf/httpd-prefix.conf"

I just commented it with #,

Now it's running fine. :)

You can achieve this by adding border class of bootstrap

like for border left ,you can use border-left

Pass by const reference unless there is a reason you wish to change/keep the contents you are passing in.

This will be the most efficient method in most cases.

Make sure you use const on each parameter you do not wish to change, as this not only protects you from doing something stupid in the function, it gives a good indication to other users what the function does to the passed in values. This includes making a pointer const when you only want to change whats pointed to...

For CDT users / C/C++ build, also adjust the setting

in Window > Preferences

under C/C++ > Build > Console (!)

(This time in number of lines.)

This also affects the "CDT Global Build Console".

You do not need to use the while True: loop in this case. There is a much simpler way to use the time condition directly:

import time

# timeout variable can be omitted, if you use specific value in the while condition
timeout = 300   # [seconds]

timeout_start = time.time()

while time.time() < timeout_start + timeout:
    test = 0
    if test == 5:
        break
    test -= 1

SELECT DISTINCT C.valueC 
FROM C 
  LEFT JOIN B ON C.id = B.lookupC
  LEFT JOIN A ON B.id = A.lookupB
WHERE C.id IS NOT NULL

I don't see a good reason why you want to limit the result sets of A and B because what you want to have is a list of all C's that are referenced by A. I did a distinct on C.valueC because i guessed you wanted a unique list of C's.

EDIT: I agree with your argument. Even if your solution looks a bit nested it seems to be the best and fastest way to use your knowledge of the data and reduce the result sets.

There is no distinct join construct you could use so just stay with what you already have :)

FOR the best performance, use specific column name instead of * - for example:

SELECT TOP 1 <columnName> 
FROM <tableName> 

This is optimal because, instead of returning the whole list of columns, it is returning just one. That can save some time.

Also, returning just first row if there are any values, makes it even faster. Actually you got just one value as the result - if there are any rows, or no value if there is no rows.

If you use the table in distributed manner, which is most probably the case, than transporting just one value from the server to the client is much faster.

You also should choose wisely among all the columns to get data from a column which can take as less resource as possible.

This seemed to have worked for me!

Mat a_image = imread(argv[1]);

cvtColor(a_image, a_image, CV_BGR2GRAY);
GaussianBlur(a_image, a_image, Size(7,7), 1.5, 1.5);
threshold(a_image, a_image, 100, 255, CV_THRESH_BINARY);

another method to find Instance name- Right clck on Database name and select Properties, in this part you can see view connection properties in left down corner, click that then you can see the Instance name.

Not sure why, but you can wrap DateTime.ToUniversalTime in a try / catch and achieve the same result in more code.

Good luck.

Let me introduce you to my friend "dotglob". It turns on and off whether or not "*" includes hidden files.

$ mkdir test
$ cd test
$ touch a b c .hidden .hi .den
$ ls -a
. ..  .den  .hi .hidden a b c

$ shopt -u dotglob
$ ls *
a b c
$ for i in * ; do echo I found: $i ; done
I found: a
I found: b
I found: c

$ shopt -s dotglob
$ ls *
.den  .hi .hidden a b c
$ for i in * ; do echo I found: $i ; done
I found: .den
I found: .hi
I found: .hidden
I found: a
I found: b
I found: c

It defaults to "off".

$ shopt dotglob
dotglob         off

It is best to turn it back on when you are done otherwise you will confuse things that assume it will be off.

check

System.getProperty("sun.jnu.encoding")

it seems to be the same encoding as the one used in your system's command line.

Here is a simple one liner

var segment = (arr, n) => arr.reduce((r,e,i) => i%n ? (r[r.length-1].push(e), r)_x000D_
                                                    : (r.push([e]), r), []),_x000D_
        arr = Array.from({length: 31}).map((_,i) => i+1);_x000D_
console.log(segment(arr,7));

To actually do it in HTML with inline CSS (not with an external CSS style sheet)

<input type="text" style="font-size: 44pt">

A lot of people would consider putting the style right into the html like this to be poor form. However, I frequently make extreeemly simple web pages for my own use that don't even have a <html> or <body> tag, and such is appropriate there.

If you deal with .xlsm file instead of .xls you can use the old method. I was trying to modify vbaProject.bin in .xlsm several times using DBP->DBx method by it didn't work, also changing value of DBP didn't. So I was very suprised that following worked :
1. Save .xlsm as .xls.
2. Use DBP->DBx method on .xls.
3. Unfortunately some erros may occur when using modified .xls file, I had to save .xls as .xlsx and add modules, then save as .xlsm.

Seems like last_accessed_on, is a date time, and you are converting '23-07-2014 09:37:00' to a varchar. This would not work, and give you conversion errors. Try

last_accessed_on= convert(datetime,'23-07-2014 09:37:00', 103)  

I think you can avoid the cast though, and update with '23-07-2014 09:37:00'. It should work given that the format is correct.

Your query is not going to work because in last_accessed_on (which is DateTime2 type), you are trying to pass a Varchar value.

You query would be

UPDATE  student_queues SET  Deleted=0 ,  last_accessed_by='raja', last_accessed_on=convert(datetime,'23-07-2014 09:37:00', 103)  
 WHERE std_id IN ('2144-384-11564') AND reject_details='REJECT'

That's really an informational message.

Likely, you're doing OPTIMIZE on an InnoDB table (table using the InnoDB storage engine, rather than the MyISAM storage engine).

InnoDB doesn't support the OPTIMIZE the way MyISAM does. It does something different. It creates an empty table, and copies all of the rows from the existing table into it, and essentially deletes the old table and renames the new table, and then runs an ANALYZE to gather statistics. That's the closest that InnoDB can get to doing an OPTIMIZE.

The message you are getting is basically MySQL server repeating what the InnoDB storage engine told MySQL server:

Table does not support optimize is the InnoDB storage engine saying...

"I (the InnoDB storage engine) don't do an OPTIMIZE operation like my friend (the MyISAM storage engine) does."

"doing recreate + analyze instead" is the InnoDB storage engine saying...

"I have decided to perform a different set of operations which will achieve an equivalent result."

Yes,u can overload main method but the interpreter will always search for the correct main method syntax to begin the execution.. And yes u have to call the overloaded main method with the help of object.

class Sample{
public void main(int a,int b){
System.out.println("The value of a is "  +a);
}
public static void main(String args[]){
System.out.println("We r in main method");
Sample obj=new Sample();
obj.main(5,4);
main(3);
}
public static void main(int c){
System.out.println("The value of c  is"  +c);
}
}

The output of the program is:
We r in main method
The value of a is 5
The value of c is 3

As others have pointed out one could just delete all the files in the repo and then check them out. I prefer this method and it can be done with the code below

git ls-files -z | xargs -0 rm
git checkout -- .

or one line

git ls-files -z | xargs -0 rm ; git checkout -- .

I use it all the time and haven't found any down sides yet!

For some further explanation, the -z appends a null character onto the end of each entry output by ls-files, and the -0 tells xargs to delimit the output it was receiving by those null characters.

for VS2008 with feature pack update, shared_ptr can be found under namespace std::tr1.

std::tr1::shared_ptr<int> MyIntSmartPtr = new int;

of

if you had boost installation path (for example @ C:\Program Files\Boost\boost_1_40_0) added to your IDE settings:

#include <boost/shared_ptr.hpp>

If you are passing user credential from client (As per below code block), then it should match with the username/password on server. otherwise you will get this error.

FYI, in my case I am using "basicHTTPAuthentication" with "TransportWithMessageCredential" security mode. And the WCF service is hosted in IIS on https.

var service = new TestService();

service.ClientCredentials.UserName.UserName = "InvalidUser";
service.ClientCredentials.UserName.Password = "InvalidPass";

Hope this will help to someone... :)

private static void printStar(int x) {
    int i, j;
    for (int y = 0; y < x; y++) { // number of row of '*'

        for (i = y; i < x - 1; i++)
            // number of space each row
            System.out.print(' ');

        for (j = 0; j < y * 2 + 1; j++)
            // number of '*' each row
            System.out.print('*');

        System.out.println();
    }
}

untested: wouldn't this work?

<?php
$last_element=end(array_values($array));
?>

Since the array returned by array_values is fleeting, no-one cares if it's pointer is reset.

and if you need the key to go with it I guess you'd do:

<?php
$last_key=end(array_keys($array));
?>

Here is a test I created on jsperf: https://jsperf.com/vanillajs-loop-through-elements-of-class

The most perfomant version in Chrome and Firefox is the good old for loop in combination with document.getElementsByClassName:

var elements = document.getElementsByClassName('testClass'), elLength = elements.length;
for (var i = 0; i < elLength; i++) {
    elements.item(i).textContent = 'Tested';
};

In Safari this variant is the winner:

var elements = document.querySelectorAll('.testClass');
elements.forEach((element) => {
    element.textContent = 'Tested';
});

If you want the most perfomant variant for all browsers it might be this one:

var elements = document.getElementsByClassName('testClass');
Array.from(elements).map(
    (element) => {
        return element.textContent = 'Tested';
    }
);

I don't understand the need of having private setters which started with C# 2.

Use case example:

I have an instance of an application object 'UserInfo' that contains a property SessionTokenIDV1 that I don't wish to expose to consumers of my class.

I also need the ability to set that value from my class.

My solution was to encapsulate the property as shown and make the setter private so that I can set the value of the session token without allowing instantiating code to also set it (or even see it in my case)

public class UserInfo
{
   public String SessionTokenIDV1 { get; set; }

}


public class Example
{
  // Private vars
  private UserInfo _userInfo = new UserInfo();

  public string SessionValidV1
  {
    get { return ((_userInfo.SessionTokenIDV1 != null) && (_userInfo.SessionTokenIDV1.Length > 0)) ? "set" : "unset"; }
    private set { _userInfo.SessionTokenIDV1 = value; }
  }
}

Edit: Fixed Code Tag Edit: Example had errors which have been corrected

For background images, make sure to use url()

node.backgroundImage = 'url(' + e.target.result + ')';

While the DateTime.Kind property does not have a setter, the static method DateTime.SpecifyKind creates a DateTime instance with a specified value for Kind.

Altenatively there are several DateTime constructor overloads that take a DateTimeKind parameter

Warning: Google Play violation

Google has threatened to remove apps from the Play Store if they use accessibility services for non-accessibility purposes. However, this is reportedly being reconsidered.

Use an AccessibilityService

• You can detect the currently active window by using an AccessibilityService.
• In the onAccessibilityEvent callback, check for the TYPE_WINDOW_STATE_CHANGED event type to determine when the current window changes.
• Check if the window is an activity by calling PackageManager.getActivityInfo().

Benefits

• Tested and working in Android 2.2 (API 8) through Android 7.1 (API 25).
• Doesn't require polling.
• Doesn't require the GET_TASKS permission.

Disadvantages

• Each user must enable the service in Android's accessibility settings.
• This isn't 100% reliable. Occasionally the events come in out-of-order.
• The service is always running.
• When a user tries to enable the AccessibilityService, they can't press the OK button if an app has placed an overlay on the screen. Some apps that do this are Velis Auto Brightness and Lux. This can be confusing because the user might not know why they can't press the button or how to work around it.
• The AccessibilityService won't know the current activity until the first change of activity.

Example

Service

public class WindowChangeDetectingService extends AccessibilityService {

    @Override
    protected void onServiceConnected() {
        super.onServiceConnected();

        //Configure these here for compatibility with API 13 and below.
        AccessibilityServiceInfo config = new AccessibilityServiceInfo();
        config.eventTypes = AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED;
        config.feedbackType = AccessibilityServiceInfo.FEEDBACK_GENERIC;

        if (Build.VERSION.SDK_INT >= 16)
            //Just in case this helps
            config.flags = AccessibilityServiceInfo.FLAG_INCLUDE_NOT_IMPORTANT_VIEWS;

        setServiceInfo(config);
    }

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {
        if (event.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED) {
            if (event.getPackageName() != null && event.getClassName() != null) {
                ComponentName componentName = new ComponentName(
                    event.getPackageName().toString(),
                    event.getClassName().toString()
                );

                ActivityInfo activityInfo = tryGetActivity(componentName);
                boolean isActivity = activityInfo != null;
                if (isActivity)
                    Log.i("CurrentActivity", componentName.flattenToShortString());
            }
        }
    }

    private ActivityInfo tryGetActivity(ComponentName componentName) {
        try {
            return getPackageManager().getActivityInfo(componentName, 0);
        } catch (PackageManager.NameNotFoundException e) {
            return null;
        }
    }

    @Override
    public void onInterrupt() {}
}

AndroidManifest.xml

Merge this into your manifest:

<application>
    <service
        android:label="@string/accessibility_service_name"
        android:name=".WindowChangeDetectingService"
        android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE">
        <intent-filter>
            <action android:name="android.accessibilityservice.AccessibilityService"/>
        </intent-filter>
        <meta-data
            android:name="android.accessibilityservice"
            android:resource="@xml/accessibilityservice"/>
    </service>
</application>

Service Info

Put this in res/xml/accessibilityservice.xml:

<?xml version="1.0" encoding="utf-8"?>
<!-- These options MUST be specified here in order for the events to be received on first
 start in Android 4.1.1 -->
<accessibility-service
    xmlns:tools="http://schemas.android.com/tools"
    android:accessibilityEventTypes="typeWindowStateChanged"
    android:accessibilityFeedbackType="feedbackGeneric"
    android:accessibilityFlags="flagIncludeNotImportantViews"
    android:description="@string/accessibility_service_description"
    xmlns:android="http://schemas.android.com/apk/res/android"
    tools:ignore="UnusedAttribute"/>

Enabling the Service

Each user of the app will need to explicitly enable the AccessibilityService in order for it to be used. See this StackOverflow answer for how to do this.

Note that the user won't be able to press the OK button when trying to enable the accessibility service if an app has placed an overlay on the screen, such as Velis Auto Brightness or Lux.

For a more aesthetic appearance :) can be:

left:-9999em; 
top:-9999em; 

position for .sNv2 .nav UL can be replaced by z-index:-1 and z-index:1 for .sNv2 .nav LI:Hover UL

1. Open your SQL command line and type the following:

   SQL> connect / as sysdba
   

2. Once connected,you can enter the following query to get details of username and password:

   SQL> select username,password from dba_users;
   

3. This will list down the usernames,but passwords would not be visible.But you can identify the particular username and then change the password for that user. For changing the password,use the below query:

   SQL> alter user username identified by password;
   

4. Here username is the name of user whose password you want to change and password is the new password.

You should use npm run-script build or npm build <project_folder>. More info here: https://docs.npmjs.com/cli/build.

here is one line code

name = (city.getName() != null) ? city.getName() : "N/A";

here is example how it work, run below code in js file and understand the result. This ("Data" != null) is condition as we do in normal if() and "Data" is statement when this condition became true. this " : " act as else and "N/A" is statement for else condition. Hope this help you to understand the logic.

name = ("Data" != null) ? "Data" : "N/A";_x000D_
_x000D_
console.log(name);

If your label is long and goes on multiple rows setting the width and display:inline-block will help.

.form-field * {
  vertical-align: middle;
}
.form-field input {
  clear:left;
}
.form-field label { 
  width:200px;
  display:inline-block;
}

<div class="form-field">
    <input id="option1" type="radio" name="opt" value="1"/>
    <label for="option1">Option 1 is very long and is likely to go on two lines.</label>
    <input id="option2" type="radio" name="opt" value="2"/>
    <label for="option2">Option 2 might fit into one line.</label>
</div>

When dealing with mocking lists and iterating them, I always use something like:

@Spy
private List<Object> parts = new ArrayList<>();

First We Need To Write into our Memory Stream and then with the help of Memory Stream method "WriteTo" we can write to the Response of the Page as shown in the below code.

   MemoryStream filecontent = null;
   filecontent =//CommonUtility.ExportToPdf(inputXMLtoXSLT);(This will be your MemeoryStream Content)
   Response.ContentType = "image/pdf";
   string headerValue = string.Format("attachment; filename={0}", formName.ToUpper() + ".pdf");
   Response.AppendHeader("Content-Disposition", headerValue);

   filecontent.WriteTo(Response.OutputStream);

   Response.End();

FormName is the fileName given,This code will make the generated PDF file downloadable by invoking a PopUp.

Did you add firefox to your path after you have started the selenium server? If that is the case selenium will still use old path. The solution is to tear down & restart selenium so that it will use the updated Path environment variable.

To check if firefox is added in your path correctly you can just launch a command line terminal "cmd" and type "firefox" + ENTER there. If firefox starts then everything is alright and restarting selenium server should fix the problem.

You can cast your timestamp to a date by suffixing it with ::date. Here, in psql, is a timestamp:

# select '2010-01-01 12:00:00'::timestamp;
      timestamp      
---------------------
 2010-01-01 12:00:00

Now we'll cast it to a date:

wconrad=# select '2010-01-01 12:00:00'::timestamp::date;
    date    
------------
 2010-01-01

On the other hand you can use date_trunc function. The difference between them is that the latter returns the same data type like timestamptz keeping your time zone intact (if you need it).

=> select date_trunc('day', now());
       date_trunc
------------------------
 2015-12-15 00:00:00+02
(1 row)

Basically you need following things to make location detector android app

• Location Listener, which detect current location
• Marker to add and animate when person moves
• Polyline to add path on person's movement
• Services for sending and receiving location
• Rest API / Firebase Realtime Database to store and fetch locations

Now if you write each of these module yourself then it needs much time and efforts. So it would be better to use ready resources that are being maintained already.

Using all these resources, you will be able to create an flawless android location detection app.

1. Location Listening

You will first need to listen for current location of user. You can use any of below libraries to quick start.

Google Play Location Samples

This library provide last known location, location updates

Location Manager

With this library you just need to provide a Configuration object with your requirements, and you will receive a location or a fail reason with all the stuff are described above handled.

Live Location Sharing

Use this open source repo of the Hypertrack Live app to build live location sharing experience within your app within a few hours. HyperTrack Live app helps you share your Live Location with friends and family through your favorite messaging app when you are on the way to meet up. HyperTrack Live uses HyperTrack APIs and SDKs.

2. Markers Library

Google Maps Android API utility library

• Marker clustering — handles the display of a large number of points
• Heat maps — display a large number of points as a heat map
• IconGenerator — display text on your Markers
• Poly decoding and encoding — compact encoding for paths, interoperability with Maps API web services
• Spherical geometry — for example: computeDistance, computeHeading, computeArea
• KML — displays KML data
• GeoJSON — displays and styles GeoJSON data

3. Polyline Libraries

DrawRouteMaps

If you want to add route maps feature in your apps you can use DrawRouteMaps to make you work more easier. This is lib will help you to draw route maps between two point LatLng.

trail-android

Simple, smooth animation for route / polylines on google maps using projections. (WIP)

Google-Directions-Android

This project allows you to calculate the direction between two locations and display the route on a Google Map using the Google Directions API.

A map demo app for quick start with maps

Pivot table Excel2007- average to exclude zeros

=sum(XX:XX)/count if(XX:XX, ">0")

Invoice USD

Qty Rate(count) Value (sum) 300 0.000 000.000 1000 0.385 385.000

Average Rate Count should Exclude 0.000 rate

There is another library with much cleaner API and type-safe data. https://github.com/kodart/Httpzoid

Here is a simple usage example

Http http = HttpFactory.create(context);
http.post("http://example.com/users")
    .data(new User("John"))
    .execute();

Or more complex with callbacks

Http http = HttpFactory.create(context);
http.post("http://example.com/users")
    .data(new User("John"))
    .handler(new ResponseHandler<Void>() {
        @Override
        public void success(Void ignore, HttpResponse response) {
        }

        @Override
        public void error(String message, HttpResponse response) {
        }

        @Override
        public void failure(NetworkError error) {
        }

        @Override
        public void complete() {
        }
    }).execute();

It is fresh new, but looks very promising.

You can also do

 Pushd "%~dp0"

Which also takes running from a unc path into consideration.

Actually, the best way is the way Google recommends. Double quotes: https://google.github.io/styleguide/htmlcssguide.xml?showone=HTML_Quotation_Marks#HTML_Quotation_Marks

See https://google.github.io/styleguide/htmlcssguide.xml?showone=HTML_Validity#HTML_Validity Quoted Advice from Google: "Using valid HTML is a measurable baseline quality attribute that contributes to learning about technical requirements and constraints, and that ensures proper HTML usage."

I had the same issue. I solved it by running the command in a different python version. I tried python3 filename.py. Earlier i was using Python 2.7.

Another possibility is that the file from which something is imported may contain BOM (Byte Order Mark). It can be solved by opening the file in some editor which supports multiple encoding like VSCode (Notepad++) and saving in a different encoding statndard like ANSI, UTF-8(without BOM).

Simplest is to use Match

If Not IsError(Application.Match(ValueToSearchFor, RangeToSearchIn, 0)) Then
    ' String is in range

GregorianCalendar c = new GregorianCalendar();
c.setTime(yourDate);
XMLGregorianCalendar date2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(c);

Easiest method: Alt+Enter on

private static final long serialVersionUID = ;

IntelliJ will underline the space after the =. put your cursor on it and hit alt+Enter (Option+Enter on Mac). You'll get a popover that says "Randomly Change serialVersionUID Initializer". Just hit enter, and it'll populate that space with a random long.

Have you noticed that you don't get the error if you run

python ./script.py

instead of

python script.py

This is because sys.argv[0] will read ./script.py in the former case, which gives os.path.dirname something to work with. When you don't specify a path, sys.argv[0] reads simply script.py, and os.path.dirname cannot determine a path.

I think this is only partially true. Changing the format seems to switch the date to a string object which then has no methods like AddDays to manipulate it. So to make this work, you have to switch it back to a date. For example:

Get-Date (Get-Date).AddDays(-1) -format D

Swift 5 Notification Observer

override func viewDidLoad() {
    super.viewDidLoad() 
    NotificationCenter.default.addObserver(self, selector: #selector(batteryLevelChanged), name: UIDevice.batteryLevelDidChangeNotification, object: nil)
}

@objc func batteryLevelChanged(notification : NSNotification){
    //do here code
}

override func viewWillDisappear(_ animated: Bool) {
    NotificationCenter.default.removeObserver(self, name: UIDevice.batteryLevelDidChangeNotification, object: nil)

}

Please check if your code doesnt consist of two module projects that have the same classes names and packages definition. For example this could happen if someone uses copy-paste to create new implementation of interface based on previous implementation.

Make outer <div> to position: relative and inner <div> to position: absolute. It should work for you.

you can add tag without any text but with link. and when you click the button like you have in code , just run the $("yourlinkclass").click() function.

The problem located on the following line

SELECT  @Prefix + LEN(CAST(@maxCode AS VARCHAR(10))+1) + CAST(@maxCode AS VARCHAR(100))

Use this instead

SELECT  @Prefix + CAST(LEN(CAST(@maxCode AS VARCHAR(10))+1) AS VARCHAR(100)) + CAST(@maxCode AS VARCHAR(100))

Full Code:

CREATE PROC [dbo].[getVoucherNo]

AS

BEGIN

    DECLARE @Prefix VARCHAR(10)='J'

    DECLARE @startFrom INT=1

    DECLARE @maxCode VARCHAR(100)

    DECLARE @sCode INT

    IF((SELECT COUNT(*) FROM dbo.Journal_Entry) > 0)
    BEGIN
        SELECT @maxCode = CAST(MAX(CAST(SUBSTRING(VoucharNo,LEN(@startFrom)+1,LEN(VoucharNo)- LEN(@Prefix)) AS INT))+1 AS varchar(100)) FROM dbo.Journal_Entry;
        SET @sCode=CAST(@maxCode AS INT)
        SELECT  @Prefix + CAST(LEN(CAST(@maxCode AS VARCHAR(10))+1) AS VARCHAR(100)) + CAST(@maxCode AS VARCHAR(100))
    END
    ELSE
    BEGIN
        SELECT(@Prefix + CAST(@startFrom AS VARCHAR)) 
    END
END

if you inistalled mysql Independently you can stop mysql service if running no one of these answers are worked for me this work for me

Although this is an old question, I had the same question when using the Standard console version. The answer can be found in the Debian Live manual under the section 10.1 Customizing the live user. It says:

It is also possible to change the default username "user" and the default password "live".

I tried the username user and password live and it did work. If you want to run commands as root you can preface each command with sudo

alternatively, you can try writing a specific element:

    //label[1] is the first element.
    el =  await driver.findElement(By.xpath("//div[@class=\"facetContainerDiv\"]/div/label[1]/input")));
    await el.click();

I'd really like to be able to specify database indexes in a standardized way but, sadly, this is not part of the JPA specification (maybe because DDL generation support is not required by the JPA specification, which is a kind of road block for such a feature).

So you'll have to rely on a provider specific extension for that. Hibernate, OpenJPA and EclipseLink clearly do offer such an extension. I can't confirm for DataNucleus but since indexes definition is part of JDO, I guess it does.

I really hope index support will get standardized in next versions of the specification and thus somehow disagree with other answers, I don't see any good reason to not include such a thing in JPA (especially since the database is not always under your control) for optimal DDL generation support.

By the way, I suggest downloading the JPA 2.0 spec.

Just make all users who log in subscribe to a specific topic, and then send a notification to that topic.

Windows 10 - when upgrading from AS 2.x to 3.01

None of the above solutions are going to work.

Try this:

function filter_html($value){
    $value = mb_convert_encoding($value, 'ISO-8859-1', 'UTF-8');
    return $value;
}

Note that there are other ways of achieving data consistency that #pragma pack offers (for instance some people use #pragma pack(1) for structures that should be sent across the network). For instance, see the following code and its subsequent output:

#include <stdio.h>

struct a {
    char one;
    char two[2];
    char eight[8];
    char four[4];
};

struct b { 
    char one;
    short two;
    long int eight;
    int four;
};

int main(int argc, char** argv) {
    struct a twoa[2] = {}; 
    struct b twob[2] = {}; 
    printf("sizeof(struct a): %i, sizeof(struct b): %i\n", sizeof(struct a), sizeof(struct b));
    printf("sizeof(twoa): %i, sizeof(twob): %i\n", sizeof(twoa), sizeof(twob));
}

The output is as follows: sizeof(struct a): 15, sizeof(struct b): 24 sizeof(twoa): 30, sizeof(twob): 48

Notice how the size of struct a is exactly what the byte count is, but struct b has padding added (see this for details on the padding). By doing this as opposed to the #pragma pack you can have control of converting the "wire format" into the appropriate types. For instance, "char two[2]" into a "short int" et cetera.

A bit late for this, but this thread comes up in Google as a top result when searching for an overlay method.

You could simply use a background-blend-mode

.foo {
    background-image: url(images/image1.png), url(images/image2.png);
    background-color: violet;
    background-blend-mode: screen multiply;
}

What this does is it takes the second image, and it blends it with the background colour by using the multiply blend mode, and then it blends the first image with the second image and the background colour by using the screen blend mode. There are 16 different blend modes that you could use to achieve any overlay.

multiply, screen, overlay, darken, lighten, color-dodge, color-burn, hard-light, soft-light, difference, exclusion, hue, saturation, color and luminosity.

Use the Find method if item_manuf_id is a primary key:

var result = dtPs.Rows.Find("some value");

If you only want to know if the value is in there then use the Contains method.

if (dtPs.Rows.Contains("some value"))
{
  ...
}

Primary key restriction applies to Contains aswell.

I have a nodeJs project and lost my folders after removing the /[project_name].iml file.

This restored the folders while preserving my other project settings:

• Project Settings > Modules
• + Add Content Root

Connecting a method call to the method body is known as Binding. As Maulik said "Static binding uses Type(Class in Java) information for binding while Dynamic binding uses Object to resolve binding." So this code :

public class Animal {
    void eat() {
        System.out.println("animal is eating...");
    }
}

class Dog extends Animal {

    public static void main(String args[]) {
        Animal a = new Dog();
        a.eat(); // prints >> dog is eating...
    }

    @Override
    void eat() {
        System.out.println("dog is eating...");
    }
}

Will produce the result: dog is eating... because it is using the object reference to find which method to use. If we change the above code to this:

class Animal {
    static void eat() {
        System.out.println("animal is eating...");
    }
}

class Dog extends Animal {

    public static void main(String args[]) {

        Animal a = new Dog();
        a.eat(); // prints >> animal is eating...

    }

    static void eat() {
        System.out.println("dog is eating...");
    }
}

It will produce : animal is eating... because it is a static method, so it is using Type (in this case Animal) to resolve which static method to call. Beside static methods private and final methods use the same approach.

The PHPUnit expectException method is very inconvenient because it allows to test only one exception per a test method.

I've made this helper function to assert that some function throws an exception:

/**
 * Asserts that the given callback throws the given exception.
 *
 * @param string $expectClass The name of the expected exception class
 * @param callable $callback A callback which should throw the exception
 */
protected function assertException(string $expectClass, callable $callback)
{
    try {
        $callback();
    } catch (\Throwable $exception) {
        $this->assertInstanceOf($expectClass, $exception, 'An invalid exception was thrown');
        return;
    }

    $this->fail('No exception was thrown');
}

Add it to your test class and call this way:

public function testSomething() {
    $this->assertException(\PDOException::class, function() {
        new \PDO('bad:param');
    });
    $this->assertException(\PDOException::class, function() {
        new \PDO('foo:bar');
    });
}

Unfortunately there is nothing like this in TypeScript (more details here: https://github.com/Microsoft/TypeScript/issues/467)

But to get around this you can change your params to be an interface:

export interface IErrorParams {
  message: string;
  title?: string;
  autoHideAfter?: number;
}

export interface INotificationService {
  error(params: IErrorParams);
}

//then to call it:
error({message: 'msg', autoHideAfter: 42});

[Note: edited to modernize ggplot syntax]

Your example is not reproducible since there is no ex1221new (there is an ex1221 in Sleuth2, so I guess that is what you meant). Also, you don't need (and shouldn't) pull columns out to send to ggplot. One advantage is that ggplot works with data.frames directly.

You can set the labels with xlab() and ylab(), or make it part of the scale_*.* call.

library("Sleuth2")
library("ggplot2")
ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area() + 
  xlab("My x label") +
  ylab("My y label") +
  ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area("Nitrogen") + 
  scale_x_continuous("My x label") +
  scale_y_continuous("My y label") +
  ggtitle("Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

An alternate way to specify just labels (handy if you are not changing any other aspects of the scales) is using the labs function

ggplot(ex1221, aes(Discharge, Area)) +
  geom_point(aes(size=NO3)) + 
  scale_size_area() + 
  labs(size= "Nitrogen",
       x = "My x label",
       y = "My y label",
       title = "Weighted Scatterplot of Watershed Area vs. Discharge and Nitrogen Levels (PPM)")

which gives an identical figure to the one above.

VMDK is a virtual disk file, what you need is a VMX file. Cruise on over to EasyVMX and have it create one for you, then just replace the VMDK file it gives you with the Cnrome OS one.

EasyVMX is good since VMWare Player has no VM creation stuff in it (at least in version 2, not sure about 3). You had to use one of VMWare's other products to do that.

try to find your log file with suffix ".err", there should be more info. It might be in:

/usr/local/var/mysql/your_computer_name.local.err

It's probably problem with permissions

1. check if any mysql instance is running

   ps -ef | grep mysql

   if yes, you should stop it, or kill the process

   kill -9 PID

   where PID is the number displayed next to username on output of previous command

2. check ownership of /usr/local/var/mysql/

   ls -laF /usr/local/var/mysql/

   if it is owner by root you should change it mysql or your_user

   sudo chown -R mysql /usr/local/var/mysql/

$.each(JSON.parse(result), function(i, item) {
    alert(item.number);
});

Maybe you could try this code:

import java.io.*;
public class Test
{
public static void main(String[] args)
{
try
  {
  BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
  String userInput = in.readLine();
  System.out.println("\n\nUser entered -> " + userInput);
  }
  catch(IOException e)
  {
  System.out.println("IOException has been caught");
  }
 }
}
