Programs & Examples On #Propertyconfigurator

Try executing your command with sudo(Super User), this worked for me :)
Run : $ sudo your_command
After than enter the super user password. Thats All..

Modify your log4j.properties file accordingly:

log4j.rootLogger=TRACE,stdout
...
log4j.logger.debugLog=TRACE,debugLog
log4j.logger.reportsLog=DEBUG,reportsLog

Change the log levels for each logger depending to your needs.

I believe that the configure method expects an absolute path. Anyhow, you may also try to load a Properties object first:

Properties props = new Properties();
props.load(new FileInputStream("log4j.properties"));
PropertyConfigurator.configure(props);

If the properties file is in the jar, then you could do something like this:

Properties props = new Properties();
props.load(getClass().getResourceAsStream("/log4j.properties"));
PropertyConfigurator.configure(props);

The above assumes that the log4j.properties is in the root folder of the jar file.

Put log4j.properties in classpath. Here is the 2 cases that will help you to identify the proper location- 1. For web application the classpath is /WEB-INF/classes.

\WEB-INF      
    classes\
        log4j.properties

2. To test from main / unit test the classpath is source directory

   \Project\
      src\
         log4j.properties
   

But what if I don't know the indices of the items I want to remove?

I do not exactly understand why you do not like .remove but to get the first index corresponding to a value use .index(value):

ind=item_list.index('item')

then remove the corresponding value:

del item_list.pop[ind]

.index(value) gets the first occurrence of value, and .remove(value) removes the first occurrence of value

You could try this:

Simply place the code in a style tag in the head of the html file

<style>_x000D_
        .jumbotron {_x000D_
            background: url("http://www.californiafootgolfclub.com/static/img/footgolf-1.jpg") center center / cover no-repeat;_x000D_
        }_x000D_
</style>

or put it in a separate css file as shown below

        .jumbotron {_x000D_
            background: url("http://www.californiafootgolfclub.com/static/img/footgolf-1.jpg") center center / cover no-repeat;_x000D_
        }

use center center to center the image horizontally and vertically. use cover to make the image fill out the jumbotron space and finally no-repeat so that the image is not repeated.

I wanted to provide with a solution inspired by physics.

Imagine a force applied along the line and you are measuring the torque of the force about the point. If the torque is positive (counterclockwise) then the point is to the "left" of the line, but if the torque is negative the point is the "right" of the line.

So if the force vector equals the span of the two points defining the line

fx = x_2 - x_1
fy = y_2 - y_1

you test for the side of a point (px,py) based on the sign of the following test

var torque = fx*(py-y_1)-fy*(px-x_1)
if  torque>0  then
     "point on left side"
else if torque <0 then
     "point on right side"  
else
     "point on line"
end if

One of the best well-documented example I found.

In my case, the problem was fixed by going into my build.gradle and changing

dependencies {
    testImplementation 'junit:junit:4.12'
}

to

dependencies {
    testCompile 'junit:junit:4.12'
}

You can specify an array in your HTML this way:

<input type="hidden" name="id[]" value="1"/>
<input type="hidden" name="id[]" value="2"/>
<input type="hidden" name="id[]" value="3"/>

This will result in this $_GET array in PHP:

array(
  'id' => array(
    0 => 1,
    1 => 2,
    2 => 3
  )
)

Of course, you can use any sort of HTML input, here. The important thing is that all inputs whose values you want in the 'id' array have the name id[].

My Jenkins version: 1.5.39

Execute steps:

Step 1. Go to folder /Library/Application Support/Jenkins

Step 2. Run Uninstall.command jenkins-runner.sh file.

Step 3. Check result.

It work for me.

Are you familiar with the DataSet class?

The DataSet can also load XML documents and you may find it easier to iterate.

http://msdn.microsoft.com/en-us/library/system.data.dataset.readxml.aspx

DataSet dt = new DataSet();
dt.ReadXml(@"c:\test.xml");

You can paste the following code to the console to scroll up/down using the a/z keyboard keys. If you want to set your own keys you can visit this page to get the keycodes

function KeyPress(e) {
  var evtobj = window.event? event : e
  if (evtobj.keyCode == 90) {
    window.scrollBy(0, 100) 
  }
  if (evtobj.keyCode == 65) {
    window.scrollBy(0, -100) 
  }
}

document.onkeydown = KeyPress;

Post uses the message body to send the information back to the server, as opposed to Get, which uses the query string (everything after the question mark). It is possible to send both a Get query string and a Post message body in the same request, but that can get a bit confusing so is best avoided.

Generally, best practice dictates that you use Get when you want to retrieve data, and Post when you want to alter it. (These rules aren't set in stone, the specs don't forbid altering data with Get, but it's generally avoided on the grounds that you don't want people making changes just by clicking a link or typing a URL)

Conversely, you can use Post to retrieve data without changing it, but using Get means you can bookmark the page, or share the URL with other people, things you couldn't do if you'd used Post.

• http://en.wikipedia.org/wiki/GET_%28HTTP%29
• http://en.wikipedia.org/wiki/POST_%28HTTP%29

As for the actual format of the data sent in the message body, that's entirely up to the sender and is specified with the Content-Type header. If not specified, the default content-type for HTML forms is application/x-www-form-urlencoded, which means the server will expect the post body to be a string encoded in a similar manner to a GET query string. However this can't be depended on in all cases. RFC2616 says the following on the Content-Type header:

Any HTTP/1.1 message containing an entity-body SHOULD include a
Content-Type header field defining the media type of that body. If
and only if the media type is not given by a Content-Type field, the
recipient MAY attempt to guess the media type via inspection of its
content and/or the name extension(s) of the URI used to identify the
resource. If the media type remains unknown, the recipient SHOULD
treat it as type "application/octet-stream".

Your code is fine. What you are seeing is a linker issue.

If you put your code in a single file like this:

#include <iostream>
#include <string>

using namespace std;

string trim(const string& str)
{
    size_t first = str.find_first_not_of(' ');
    if (string::npos == first)
    {
        return str;
    }
    size_t last = str.find_last_not_of(' ');
    return str.substr(first, (last - first + 1));
}

int main() {
    string s = "abc ";
    cout << trim(s);

}

then do g++ test.cc and run a.out, you will see it works.

You should check if the file that contains the trim function is included in the link stage of your compilation process.

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

EXEC sp_addrolemember N'db_owner', N'USerNAme'

StringBuilder will perform replace more efficiently, since its character array buffer can be specified to a required length.StringBuilder is designed for more than appending!

Of course the real question is whether this is an optimisation too far ? The JVM is very good at handling creation of multiple objects and the subsequent garbage collection, and like all optimisation questions, my first question is whether you've measured this and determined that it's a problem.

I have built on the answer provided by fearside

This connects to an Oracle database to retrieve the progress of an RMAN restore.

Converting Simple strings

The easiest way is to use the strconv.Atoi() function.

Note that there are many other ways. For example fmt.Sscan() and strconv.ParseInt() which give greater flexibility as you can specify the base and bitsize for example. Also as noted in the documentation of strconv.Atoi():

Atoi is equivalent to ParseInt(s, 10, 0), converted to type int.

Here's an example using the mentioned functions (try it on the Go Playground):

flag.Parse()
s := flag.Arg(0)

if i, err := strconv.Atoi(s); err == nil {
    fmt.Printf("i=%d, type: %T\n", i, i)
}

if i, err := strconv.ParseInt(s, 10, 64); err == nil {
    fmt.Printf("i=%d, type: %T\n", i, i)
}

var i int
if _, err := fmt.Sscan(s, &i); err == nil {
    fmt.Printf("i=%d, type: %T\n", i, i)
}

Output (if called with argument "123"):

i=123, type: int
i=123, type: int64
i=123, type: int

Parsing Custom strings

There is also a handy fmt.Sscanf() which gives even greater flexibility as with the format string you can specify the number format (like width, base etc.) along with additional extra characters in the input string.

This is great for parsing custom strings holding a number. For example if your input is provided in a form of "id:00123" where you have a prefix "id:" and the number is fixed 5 digits, padded with zeros if shorter, this is very easily parsable like this:

s := "id:00123"

var i int
if _, err := fmt.Sscanf(s, "id:%5d", &i); err == nil {
    fmt.Println(i) // Outputs 123
}

I use

            chartRange = xlWorkSheet.Rows[1];
            chartRange.Font.Bold = true;

to turn the first-row-cells-font into bold. And it works, and I am using also Excel 2007.

You can call in VBA directly

            ActiveCell.Font.Bold = True

With this code I create a timestamp in the active cell, with bold font and yellow background

           Private Sub Worksheet_SelectionChange(ByVal Target As Range)
               ActiveCell.Value = Now()
               ActiveCell.Font.Bold = True
               ActiveCell.Interior.ColorIndex = 6
           End Sub

I dislike "Don't" answers, but... don't.

make's variables are global and are supposed to be evaluated during makefile's "parsing" stage, not during execution stage.

In this case, as long as the variable local to a single target, follow @nobar's answer and make it a shell variable.

Target-specific variables, too, are considered harmful by other make implementations: kati, Mozilla pymake. Because of them, a target can be built differently depending on if it's built standalone, or as a dependency of a parent target with a target-specific variable. And you won't know which way it was, because you don't know what is already built.

Type in command line

netstat -aon | findstr :80

You'll see PID of process which uses port 80. Then try to configure this app to use another port, or just kill it

UPDATE: I'll write my comment here to be more clear: according to this link, in Windows 10, it is the MsDepSvc service which occupies port 80. It's for IIS or Web Matrix 2. If you will not use IIS or Web Matrix 2 for any web development, you can try shutting down the service

And for the second part of your question, you can tell Apache to use another port by editing [Apache folder]/conf/httpd.conf. It has "Listen 80" string. Change 80 to whatever free port you want and reload Apache

Please check http://jsfiddle.net/GEBrW/ for live test.

You can use similar method for dynamic arrays creation.

var i = 0;
var a = new Array();

a[i++] = i;
a[i++] = i;
a[i++] = i;
a[i++] = i;
a[i++] = i;
a[i++] = i;
a[i++] = i;
a[i++] = i;

The result:

a[0] = 1
a[1] = 2
a[2] = 3
a[3] = 4
a[4] = 5
a[5] = 6
a[6] = 7
a[7] = 8

Try this , if you are using PHP 5.3+, in php

$query_date = '2010-02-04';
$date = new DateTime($query_date);
//First day of month
$date->modify('first day of this month');
$firstday= $date->format('Y-m-d');
//Last day of month
$date->modify('last day of this month');
$lastday= $date->format('Y-m-d');

For finding next month last date, modify as follows,

 $date->modify('last day of 1 month');
 echo $date->format('Y-m-d');

and so on..

if your config.properties is not in src/main/resource directory and it is in root directory of the project then you need to do somethinglike below :-

Properties prop = new Properties();          
File configFile = new File(myProp.properties);
InputStream stream = new FileInputStream(configFile);
prop.load(stream);

Memory management in Linux is a bit tricky to understand, and I can't say I fully understand it yet, but I'll try to share a little bit of my experience and knowledge.

Short answer to your question: Yes there are other stuff included than whats in the list.

What's being shown in your list is applications run in userspace. The kernel uses memory for itself and modules, on top of that it also has a lower limit of free memory that you can't go under. When you've reached that level it will try to free up resources, and when it can't do that anymore, you end up with an OOM problem.

From the last line of your list you can read that the kernel reports a total-vm usage of: 1498536kB (1,5GB), where the total-vm includes both your physical RAM and swap space. You stated you don't have any swap but the kernel seems to think otherwise since your swap space is reported to be full (Total swap = 524284kB, Free swap = 0kB) and it reports a total vmem size of 1,5GB.

Another thing that can complicate things further is memory fragmentation. You can hit the OOM killer when the kernel tries to allocate lets say 4096kB of continous memory, but there are no free ones availible.

Now that alone probably won't help you solve the actual problem. I don't know if it's normal for your program to require that amount of memory, but I would recommend to try a static code analyzer like cppcheck to check for memory leaks or file descriptor leaks. You could also try to run it through Valgrind to get a bit more information out about memory usage.

I wrote a tool to capture images from a webcam entirely in Python, based on DirectShow. You can find it here: https://github.com/andreaschiavinato/python_grabber.

You can use the whole application or just the class FilterGraph in dshow_graph.py in the following way:

from pygrabber.dshow_graph import FilterGraph
import numpy as np
from matplotlib.image import imsave

graph = FilterGraph()
print(graph.get_input_devices())
device_index = input("Enter device number: ")
graph.add_input_device(int(device_index))
graph.display_format_dialog()
filename = r"c:\temp\imm.png"
# np.flip(image, axis=2) required to convert image from BGR to RGB
graph.add_sample_grabber(lambda image : imsave(filename, np.flip(image, axis=2)))
graph.add_null_render()
graph.prepare()
graph.run()
x = input("Press key to grab photo")
graph.grab_frame()
x = input(f"File {filename} saved. Press key to end")
graph.stop()

The Problem

When an element is floated, its parent no longer contains it because the float is removed from the flow. The floated element is out of the natural flow, so all block elements will render as if the floated element is not even there, so a parent container will not fully expand to hold the floated child element.

Take a look at the following article to get a better idea of how the CSS Float property works:

The Mystery Of The CSS Float Property

A Potential Solution

Now, I think the following article resembles what you're trying to do. Take a look at it and see if you can solve your problem.

Equal Height Columns with Cross-Browser CSS

I hope this helps.

$('#form').keydown(function(e){
    if (e.keyCode === 13) { // If Enter key pressed
        $(this).trigger('submit');
    }
});

You can consider shapely:

from shapely.geometry import Point
from shapely.geometry.polygon import Polygon

point = Point(0.5, 0.5)
polygon = Polygon([(0, 0), (0, 1), (1, 1), (1, 0)])
print(polygon.contains(point))

From the methods you've mentioned I've only used the second, path.contains_points, and it works fine. In any case depending on the precision you need for your test I would suggest creating a numpy bool grid with all nodes inside the polygon to be True (False if not). If you are going to make a test for a lot of points this might be faster (although notice this relies you are making a test within a "pixel" tolerance):

from matplotlib import path
import matplotlib.pyplot as plt
import numpy as np

first = -3
size  = (3-first)/100
xv,yv = np.meshgrid(np.linspace(-3,3,100),np.linspace(-3,3,100))
p = path.Path([(0,0), (0, 1), (1, 1), (1, 0)])  # square with legs length 1 and bottom left corner at the origin
flags = p.contains_points(np.hstack((xv.flatten()[:,np.newaxis],yv.flatten()[:,np.newaxis])))
grid = np.zeros((101,101),dtype='bool')
grid[((xv.flatten()-first)/size).astype('int'),((yv.flatten()-first)/size).astype('int')] = flags

xi,yi = np.random.randint(-300,300,100)/100,np.random.randint(-300,300,100)/100
vflag = grid[((xi-first)/size).astype('int'),((yi-first)/size).astype('int')]
plt.imshow(grid.T,origin='lower',interpolation='nearest',cmap='binary')
plt.scatter(((xi-first)/size).astype('int'),((yi-first)/size).astype('int'),c=vflag,cmap='Greens',s=90)
plt.show()

, the results is this:

PHP uses Content-Type "text/html" as default - which is pretty similar to "text/plain" - and this explains why you don't see any differences. text/plain is necessary if you want to output text as is (including <>-symbols). Examples:

header("Content-Type: text/plain");
echo "<b>hello world</b>";
// Output: <b>hello world</b>

header("Content-Type: text/html");
echo "<b>hello world</b>";
// Output: hello world

I can't believe none of the answers pointed to the function dirname() (available since PHP 4).

Basically, it returns the full path for the referenced object. If you use a file as a reference, the function returns the full path of the file. If the referenced object is a folder, the function will return the parent folder of that folder.

https://www.php.net/manual/en/function.dirname.php

For the current folder of the current file, use $current = dirname(__FILE__);.

For a parent folder of the current folder, simply use $parent = dirname(__DIR__);.

For me the solution worked as by changing the url format to: con=DriverManager.getConnection("jdbc:mysql://localhost/w3schools?user=###&password=###"); make sure to add proper jar to class path and use the driver Class.forName("com.mysql.jdbc.Driver");

I just finished my weekend project cached-webpgr.js which uses the localStorage / web storage to cache JavaScript files. This approach is very fast. My small test showed

• Loading jQuery from CDN: Chrome 268ms, FireFox: 200ms
• Loading jQuery from localStorage: Chrome 47ms, FireFox 14ms

The code to achieve that is tiny, you can check it out at my Github project https://github.com/webpgr/cached-webpgr.js

Here is a full example how to use it.

The complete library:

function _cacheScript(c,d,e){var a=new XMLHttpRequest;a.onreadystatechange=function(){4==a.readyState&&(200==a.status?localStorage.setItem(c,JSON.stringify({content:a.responseText,version:d})):console.warn("error loading "+e))};a.open("GET",e,!0);a.send()}function _loadScript(c,d,e,a){var b=document.createElement("script");b.readyState?b.onreadystatechange=function(){if("loaded"==b.readyState||"complete"==b.readyState)b.onreadystatechange=null,_cacheScript(d,e,c),a&&a()}:b.onload=function(){_cacheScript(d,e,c);a&&a()};b.setAttribute("src",c);document.getElementsByTagName("head")[0].appendChild(b)}function _injectScript(c,d,e,a){var b=document.createElement("script");b.type="text/javascript";c=JSON.parse(c);var f=document.createTextNode(c.content);b.appendChild(f);document.getElementsByTagName("head")[0].appendChild(b);c.version!=e&&localStorage.removeItem(d);a&&a()}function requireScript(c,d,e,a){var b=localStorage.getItem(c);null==b?_loadScript(e,c,d,a):_injectScript(b,c,d,a)};

Calling the library

requireScript('jquery', '1.11.2', 'http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js', function(){
    requireScript('examplejs', '0.0.3', 'example.js');
});

Starting with the following sample data :

df <- data.frame(v1=letters[1:5],v2=1:5,v3=letters[10:14],stringsAsFactors=FALSE)

  v1 v2 v3
1  a  1  j
2  b  2  k
3  c  3  l
4  d  4  m
5  e  5  n

You can use :

data.frame(lapply(df, function(v) {
  if (is.character(v)) return(toupper(v))
  else return(v)
}))

Which gives :

  v1 v2 v3
1  A  1  J
2  B  2  K
3  C  3  L
4  D  4  M
5  E  5  N

I needed to convert a timeval struct (seconds, microseconds) containing UNIX time to DateTime without losing precision and haven't found an answer here so I thought I just might add mine:

DateTime _epochTime = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
private DateTime UnixTimeToDateTime(Timeval unixTime)
{
    return _epochTime.AddTicks(
        unixTime.Seconds * TimeSpan.TicksPerSecond +
        unixTime.Microseconds * TimeSpan.TicksPerMillisecond/1000);
}

To view localhost website from mobile device you have to follow thoses steps :

• In your computer, you have to retrieve your IP address (Run > cmd > ipconfig)
• If your localhost use a specific port (like localhost:12345 ), you have to open the port on your computer (Control Panel > System and Security > Firewall > Advanced settings and add Inbound rule)
• Finally, you can access to your website from mobile device by navigate to : http://192.168.X.X:12345/

Hope it helps

There is no 'DROP TABLE IF EXISTS' in oracle, you would have to do the select statement.

try this (i'm not up on oracle syntax, so if my variables are ify, please forgive me):

declare @count int
select @count=count(*) from all_tables where table_name='Table_name';
if @count>0
BEGIN
    DROP TABLE tableName;
END

from pyspark.sql.types import IntegerType
data_df = data_df.withColumn("Plays", data_df["Plays"].cast(IntegerType()))
data_df = data_df.withColumn("drafts", data_df["drafts"].cast(IntegerType()))

You can run loop for each column but this is the simplest way to convert string column into integer.

List<T>.ForEach doesn't play particularly well with async (neither does LINQ-to-objects, for the same reasons).

In this case, I recommend projecting each element into an asynchronous operation, and you can then (asynchronously) wait for them all to complete.

using (DataContext db = new DataLayer.DataContext())
{
    var tasks = db.Groups.ToList().Select(i => GetAdminsFromGroupAsync(i.Gid));
    var results = await Task.WhenAll(tasks);
}

The benefits of this approach over giving an async delegate to ForEach are:

1. Error handling is more proper. Exceptions from async void cannot be caught with catch; this approach will propagate exceptions at the await Task.WhenAll line, allowing natural exception handling.
2. You know that the tasks are complete at the end of this method, since it does an await Task.WhenAll. If you use async void, you cannot easily tell when the operations have completed.
3. This approach has a natural syntax for retrieving the results. GetAdminsFromGroupAsync sounds like it's an operation that produces a result (the admins), and such code is more natural if such operations can return their results rather than setting a value as a side effect.

var startDate = new Date($('#startDate').val());
var endDate = new Date($('#endDate').val());

if (startDate < endDate){
// Do something
}

That should do it I think

I would normally go for .loc/.iloc as suggested by Ted, but one may also select a row by tranposing the DataFrame. To stay in the example above, df.T[2] gives you row 2 of df.

Try using No Wrap - In Head or No wrap - in body in your fiddle:

Working fiddle: http://jsfiddle.net/Q5hd6/

Explanation:

Angular begins compiling the DOM when the DOM is fully loaded. You register your code to run onLoad (onload option in fiddle) => it's too late to register your myApp module because angular begins compiling the DOM and angular sees that there is no module named myApp and throws an exception.

By using No Wrap - In Head, your code looks like this:

<head>

    <script type='text/javascript' src='//cdnjs.cloudflare.com/ajax/libs/angular.js/1.2.1/angular.js'></script>

    <script type='text/javascript'>
      //Your script.
    </script>

</head>

Your script has a chance to run before angular begins compiling the DOM and myApp module is already created when angular starts compiling the DOM.

Just Additional Info which took me long time to find.what if you were using the field name and not id for identifying the form field. You do it like this:

For radio button:

var inp= $('input:radio[name=PatientPreviouslyReceivedDrug]:checked').val();

For textbox:

var txt=$('input:text[name=DrugDurationLength]').val();

In Javascript :

document.getElementById('searchField').value = '';

In jQuery :

$('#searchField').val('');

That should do it

Additional info: By default, get and set accessors are as accessible as the property itself. You can control/restrict accessor accessibility individually (for get and set) by applying more restrictive access modifiers on them.

Example:

public string Name
{
    get
    {
        return name;
    }
    protected set
    {
        name = value;
    }
}

Here get is still publicly accessed (as the property is public), but set is protected (a more restricted access specifier).

let's do try and checkout For Swift 3...

UIView.transition(with: mysuperview, duration: 0.75, options:UIViewAnimationOptions.transitionFlipFromRight , animations: {
    myview.removeFromSuperview()
}, completion: nil)

.navbar-nav {
   float: left;
   margin: 0;
   margin-left: 40%;
}

.navbar-nav.navbar-right:last-child {
   margin-right: -15px;
   margin-left: 0;
}

Updated Fiddle

Since You Have used the float property we don't have many options except to adjust it manually.

If you're using T-SQL, the only thing wrong with your code is that you used braces {} instead of parentheses ().

PS: Both IDENTITY and PRIMARY KEY imply NOT NULL, so you can omit that if you wish.

<p>
  <img style="float: right; margin: 0px 15px 15px 0px;" src="files/styles/large_hero_desktop_1x/public/headers/Kids%20on%20iPad%20 %202400x880.jpg?itok=PFa-MXyQ" width="100" />
  Nunc pulvinar lacus id purus ultrices id sagittis neque convallis. Nunc vel libero orci. 
  <br style="clear: both;" />
</p>

Append a semicolon to the following line to fix the issue.

font-family:    Arial, Helvetica, sans-serif;

deactivate is the command you are looking for. Like what has already been said, there is no command for deleting your virtual environment. Simply deactivate it!

To get all attributes of a property in a dictionary use this:

typeof(Book)
  .GetProperty("Name")
  .GetCustomAttributes(false) 
  .ToDictionary(a => a.GetType().Name, a => a);

remember to change from false to true if you want to include inheritted attributes as well.

If this helps anybody, I encountered this while using purr::map() with a function I wrote which was something like this:

find_nearby_shops <- function(base_account) {
   states_table %>% 
        filter(state == base_account$state) %>% 
        left_join(target_locations, by = c('border_states' = 'state')) %>% 
        mutate(x_latitude = base_account$latitude,
               x_longitude = base_account$longitude) %>% 
        mutate(dist_miles = geosphere::distHaversine(p1 = cbind(longitude, latitude), 
                                                     p2 = cbind(x_longitude, x_latitude))/1609.344)
}

nearby_shop_numbers <- base_locations %>% 
    split(f = base_locations$id) %>% 
    purrr::map_df(find_nearby_shops) 

I would get this error sometimes with samples, but most times I wouldn't. The root of the problem is that some of the states in the base_locations table (PR) did not exist in the states_table, so essentially I had filtered out everything, and passed an empty table on to mutate. The moral of the story is that you may have a data issue and not (just) a code problem (so you may need to clean your data.)

Thanks for agstudy and zx8754's answers above for helping with the debug.

If you're on OpenWrt or using some old version of wget which doesn't gives you -i option:

#!/bin/bash
input="text_file.txt"
while IFS= read -r line
do
  wget $line
done < "$input"

Furthermore, if you don't have wget, you can use curl or whatever you use for downloading individual files.

If you are in an activity you can use

getResources().getString(R.string.whatever_string_youWant);

If you are not in an Activity use this :

getApplicationContext.getResource().getString(R.String.Whatever_String_you_want)

1. Install Style Loader and CSS Loader:

   npm install --save-dev style-loader
   npm install --save-dev css-loader
   

2. Configure webpack

   module: {
           loaders: [
               {
                   test: /\.css$/,
                   loader: 'style-loader'
               }, {
                   test: /\.css$/,
                   loader: 'css-loader',
                   query: {
                       modules: true,
                       localIdentName: '[name]__[local]___[hash:base64:5]'
                   }
               }
           ]
       }
   

I have a this code and it will run perfectly for my site

  public function forgotpassword($pass,$name,$to)
    {
        $body ="<table  width=100% border=0><tr><td>";
        $body .= "<img width=200 src='";
        $body .= $this->imageUrl();
        $body .="'></img></td><td style=position:absolute;left:350;top:60;><h2><font color = #346699>PMS Pvt Ltd.</font><h2></td></tr>";
        $body .='<tr><td colspan=2><br/><br/><br/><strong>Dear '.$name.',</strong></td></tr>';
        $body .= '<tr><td colspan=2><br/><font size=3>As per Your request we send Your Password.</font><br/><br/>Password is : <b>'.$pass.'</b></td></tr>';
        $body .= '<tr><td colspan=2><br/>If you have any questions, please feel free to contact us at:<br/><a href="mailto:[email protected]" target="_blank">[email protected]</a></td></tr>';
        $body .= '<tr><td colspan=2><br/><br/>Best regards,<br>The PMS Team.</td></tr></table>';
        $subject = "Forgot Password";
        $this->sendmail($body,$to,$subject);
    }

mail function

   function sendmail($body,$to,$subject)
        {
            //require_once 'init.php';


            $from='[email protected]';      
            $headersfrom='';
            $headersfrom .= 'MIME-Version: 1.0' . "\r\n";
            $headersfrom .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
            $headersfrom .= 'From: '.$from.' '. "\r\n";
            mail($to,$subject,$body,$headersfrom);
        }

image url function is use for if you want to change the image you have change in only one function i have many mail function like forgot password create user there for i am use image url function you can directly set path.

function imageUrl()
    {
        return "http://".$_SERVER['SERVER_NAME'].substr($_SERVER['SCRIPT_NAME'], 0, strrpos($_SERVER['SCRIPT_NAME'], "/")+1)."images/capacity.jpg";
    }

keep.update(yoursequenceofvalues)

e.g, keep.update(xrange(11)) for your specific example. Or, if you have to produce the values in a loop for some other reason,

for ...whatever...:
  onemorevalue = ...whatever...
  keep.add(onemorevalue)

But, of course, doing it in bulk with a single .update call is faster and handier, when otherwise feasible.

function function_one() {
  function_two(); 
}

function function_two() {
//enter code here
}

//I think its simple like

#include<stdio.h>
int main()

{
int a1[100],a2[100],i,t,l1,l2,n;
printf("Enter the number of elements:\n");
scanf("%d",&n);
printf("Enter the elements:\n");
for(i=0;i<n;i++)
{
    scanf("%d",&a1[i]);
}
l1=a1[0];
for(i=0;i<n;i++)
{
    if(a1[i]>=l1)
    {
        l1=a1[i];
        t=i;
    }
}
for(i=0;i<(n-1);i++)
{
    if(i==t)
    {
        continue;
    }
    else
    {
        a2[i]=a1[i];
    }
}
l2=a2[0];
for(i=1;i<(n-1);i++)
{
    if(a2[i]>=l2 && a2[i]<l1)
    {
        l2=a2[i];
    }
}
printf("Second highest number is %d",l2);
return 0;
}

1. save this 9.png. (change name it to 9.png)

2.save it in your drawable.

3.set it to your layout.

4.set padding.

For example :

<LinearLayout  
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:background="@drawable/shadow"
  android:paddingBottom="6dp"
  android:paddingLeft="5dp"
  android:paddingRight="5dp"
  android:paddingTop="6dp"
>

.
.
.
</LinearLayout>

Use the command dir to list all the directories and files in a directory; ls is a unix command.

I Created this function:

onAddListItem: function () {
    var Modal = ReactBootstrap.Modal;
    React.render((
        <Modal title='Modal title' onRequestHide={this.hideListItem}>
            <ul class="list-group">
                <li class="list-group-item">Cras justo odio</li>
                <li class="list-group-item">Dapibus ac facilisis in</li>
                <li class="list-group-item">Morbi leo risus</li>
                <li class="list-group-item">Porta ac consectetur ac</li>
                <li class="list-group-item">Vestibulum at eros</li>
            </ul>
        </Modal>
    ), document.querySelector('#modal-wrapper'));
}

And then used it on my Button trigger.

To 'hide' the Modal:

hideListItem: function () {
    React.unmountComponentAtNode(document.querySelector('#modal-wrapper'));
},

Just type whoami in command prompt and you'll get the current username.

For your information you could use grid but with side effects :)

.parent {
  display: grid
}

I tried all the answers and nothing really worked for me.

So I've created my own method that compares simple java objects without going deep into nested structures...

Method returns null if all fields match or string containing mismatch details.

Only properties that have a getter method are compared.

How to use

        assertNull(TestUtils.diff(obj1,obj2,ignore_field1, ignore_field2));

Sample output if there is a mismatch

Output shows property names and respective values of compared objects

alert_id(1:2), city(Moscow:London)

Code (Java 8 and above):

 public static String diff(Object x1, Object x2, String ... ignored) throws Exception{
        final StringBuilder response = new StringBuilder();
        for (Method m:Arrays.stream(x1.getClass().getMethods()).filter(m->m.getName().startsWith("get")
        && m.getParameterCount()==0).collect(toList())){

            final String field = m.getName().substring(3).toLowerCase();
            if (Arrays.stream(ignored).map(x->x.toLowerCase()).noneMatch(ignoredField->ignoredField.equals(field))){
                Object v1 = m.invoke(x1);
                Object v2 = m.invoke(x2);
                if ( (v1!=null && !v1.equals(v2)) || (v2!=null && !v2.equals(v1))){
                    response.append(field).append("(").append(v1).append(":").append(v2).append(")").append(", ");
                }
            }
        }
        return response.length()==0?null:response.substring(0,response.length()-2);
    }

How about the H2 console application?

def p1( ):
    print("in p1")

def p2():
    print("in p2")

myDict={
    "P1": p1,
    "P2": p2

}

name=input("enter P1 or P2")

myDictname

This may not be a popular solution for everyone, but I like the Application Framework in Visual Basic, even when using C#.

Add a reference to Microsoft.VisualBasic

Create a class called WindowsFormsApplication

public class WindowsFormsApplication : WindowsFormsApplicationBase
{

    /// <summary>
    /// Runs the specified mainForm in this application context.
    /// </summary>
    /// <param name="mainForm">Form that is run.</param>
    public virtual void Run(Form mainForm)
    {
        // set up the main form.
        this.MainForm = mainForm;

        // Example code
        ((Form1)mainForm).FileName = this.CommandLineArgs[0];

        // then, run the the main form.
        this.Run(this.CommandLineArgs);
    }

    /// <summary>
    /// Runs this.MainForm in this application context. Converts the command
    /// line arguments correctly for the base this.Run method.
    /// </summary>
    /// <param name="commandLineArgs">Command line collection.</param>
    private void Run(ReadOnlyCollection<string> commandLineArgs)
    {
        // convert the Collection<string> to string[], so that it can be used
        // in the Run method.
        ArrayList list = new ArrayList(commandLineArgs);
        string[] commandLine = (string[])list.ToArray(typeof(string));
        this.Run(commandLine);
    }

}

Modify your Main() routine to look like this

static class Program
{

    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        var application = new WindowsFormsApplication();
        application.Run(new Form1());
    }
}

This method offers some additional usefull features (like SplashScreen support and some usefull events)

public event NetworkAvailableEventHandler NetworkAvailabilityChanged;d.
public event ShutdownEventHandler Shutdown;
public event StartupEventHandler Startup;
public event StartupNextInstanceEventHandler StartupNextInstance;
public event UnhandledExceptionEventHandler UnhandledException;

there is a quite near solution (do not fix all Paste ways) but most of them:

It works for inputs as well as for textareas:

<input type="text" ... >
<textarea ... >...</textarea>

Do like this:

<input type="text" ... onkeyup="JavaScript: ControlChanges()" onmouseup="JavaScript: ControlChanges()" >
<textarea ... onkeyup="JavaScript: ControlChanges()" onmouseup="JavaScript: ControlChanges()" >...</textarea>

As i said, not all ways to Paste fire an event on all browsers... worst some do not fire any event at all, but Timers are horrible to be used for such.

But most of Paste ways are done with keyboard and/or mouse, so normally an onkeyup or onmouseup are fired after a paste, also onkeyup is fired when typing on keyboard.

Ensure yor check code does not take much time... otherwise user get a poor impresion.

Yes, the trick is to fire on key and on mouse... but beware both can be fired, so take in mind such!!!

Main logic you have to first find how many digits are there after the decimal point.
This code works for any number upto 16 digits. If you use BigDecimal you can run it just for upto 18 digits. put the input value (your number) to the variable "num", here as an example i have hard coded it.

double num, temp=0;
double frac,j=1;

num=1034.235;
// FOR THE FRACTION PART
do{
j=j*10;
temp= num*j;
}while((temp%10)!=0);       

j=j/10;
temp=(int)num;
frac=(num*j)-(temp*j);

System.out.println("Double number= "+num);      
System.out.println("Whole part= "+(int)num+" fraction part= "+(int)frac);

Using Angular 2 (RC5) and hash-based routes, I do this:

const appRoutes: Routes = [
  ...
  {path: '_', redirectTo: '/facebookLoginSuccess'},
  ...
]

and

export const routing = RouterModule.forRoot(appRoutes, { useHash: true });

As far as I understand, the = character in the route is interpreted as part of optional route parameters definition (see https://angular.io/docs/ts/latest/guide/router.html#!#optional-route-parameters), so not involved in the route matching.

As Umesh Patil answer have comment say that there is problem. I try to edit answer and get reject. And get suggest to post new answer. This code should solve problem they have (Shashi Roy, Gaven, John Higgins).

<html> 
<head>  
<script type="text/javascript">
function CheckColors(val){
 var element=document.getElementById('othercolor');
 if(val=='others')
   element.style.display='block';
 else  
   element.style.display='none';
}

</script> 
</head>
<body>
  <select name="color" onchange='CheckColors(this.value);'> 
    <option>pick a color</option>  
    <option value="red">RED</option>
    <option value="blue">BLUE</option>
    <option value="others">others</option>
  </select>
<input type="text" name="othercolor" id="othercolor" style='display:none;'/>
</body>
</html>

For me, I forgot to add the default serial id.

private static final long serialVersionUID = 1L;

This will add an image to another.

using (Graphics grfx = Graphics.FromImage(image))
{
    grfx.DrawImage(newImage, x, y)
}

Graphics is in the namespace System.Drawing

You are correct in that static files are copied to the application at link-time, and that shared files are just verified at link time and loaded at runtime.

The dlopen call is not only for shared objects, if the application wishes to do so at runtime on its behalf, otherwise the shared objects are loaded automatically when the application starts. DLLS and .so are the same thing. the dlopen exists to add even more fine-grained dynamic loading abilities for processes. You dont have to use dlopen yourself to open/use the DLLs, that happens too at application startup.

FYI, I combined Keremk's answer with my original outline, cleaned-up the typos, generalized it to return an array of colors and got the whole thing to compile. Here is the result:

+ (NSArray*)getRGBAsFromImage:(UIImage*)image atX:(int)x andY:(int)y count:(int)count
{
    NSMutableArray *result = [NSMutableArray arrayWithCapacity:count];

    // First get the image into your data buffer
    CGImageRef imageRef = [image CGImage];
    NSUInteger width = CGImageGetWidth(imageRef);
    NSUInteger height = CGImageGetHeight(imageRef);
    CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
    unsigned char *rawData = (unsigned char*) calloc(height * width * 4, sizeof(unsigned char));
    NSUInteger bytesPerPixel = 4;
    NSUInteger bytesPerRow = bytesPerPixel * width;
    NSUInteger bitsPerComponent = 8;
    CGContextRef context = CGBitmapContextCreate(rawData, width, height,
                    bitsPerComponent, bytesPerRow, colorSpace,
                    kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big);
    CGColorSpaceRelease(colorSpace);

    CGContextDrawImage(context, CGRectMake(0, 0, width, height), imageRef);
    CGContextRelease(context);

    // Now your rawData contains the image data in the RGBA8888 pixel format.
    NSUInteger byteIndex = (bytesPerRow * y) + x * bytesPerPixel;
    for (int i = 0 ; i < count ; ++i)
    {
        CGFloat alpha = ((CGFloat) rawData[byteIndex + 3] ) / 255.0f;
        CGFloat red   = ((CGFloat) rawData[byteIndex]     ) / alpha;
        CGFloat green = ((CGFloat) rawData[byteIndex + 1] ) / alpha;
        CGFloat blue  = ((CGFloat) rawData[byteIndex + 2] ) / alpha;
        byteIndex += bytesPerPixel;

        UIColor *acolor = [UIColor colorWithRed:red green:green blue:blue alpha:alpha];
        [result addObject:acolor];
    }

  free(rawData);

  return result;
}

It's easy to detect the image orientation and replace the bitmap using:

 /**
 * Rotate an image if required.
 * @param img
 * @param selectedImage
 * @return
 */
private static Bitmap rotateImageIfRequired(Context context,Bitmap img, Uri selectedImage) {

    // Detect rotation
    int rotation = getRotation(context, selectedImage);
    if (rotation != 0) {
        Matrix matrix = new Matrix();
        matrix.postRotate(rotation);
        Bitmap rotatedImg = Bitmap.createBitmap(img, 0, 0, img.getWidth(), img.getHeight(), matrix, true);
        img.recycle();
        return rotatedImg;
    }
    else{
        return img;
    }
}

/**
 * Get the rotation of the last image added.
 * @param context
 * @param selectedImage
 * @return
 */
private static int getRotation(Context context,Uri selectedImage) {

    int rotation = 0;
    ContentResolver content = context.getContentResolver();

    Cursor mediaCursor = content.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                                       new String[] { "orientation", "date_added" },
                                       null, null, "date_added desc");

    if (mediaCursor != null && mediaCursor.getCount() != 0) {
        while(mediaCursor.moveToNext()){
            rotation = mediaCursor.getInt(0);
            break;
        }
    }
    mediaCursor.close();
    return rotation;
}

To avoid Out of memories with big images, I'd recommend you to rescale the image using:

private static final int MAX_HEIGHT = 1024;
private static final int MAX_WIDTH = 1024;
public static Bitmap decodeSampledBitmap(Context context, Uri selectedImage)
    throws IOException {

    // First decode with inJustDecodeBounds=true to check dimensions
    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;
    InputStream imageStream = context.getContentResolver().openInputStream(selectedImage);
    BitmapFactory.decodeStream(imageStream, null, options);
    imageStream.close();

Try this

UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController *vc = [mainStoryboard instantiateViewControllerWithIdentifier:@"Login"];

[[UIApplication sharedApplication].keyWindow setRootViewController:vc];

If the first segment doesn't start with / it is a relative route. router.navigate needs a relativeTo parameter for relative navigation

Either you make the route absolute:

this.router.navigate(['/foo-content', 'bar-contents', 'baz-content', 'page'], this.params.queryParams)

or you pass relativeTo

this.router.navigate(['../foo-content', 'bar-contents', 'baz-content', 'page'], {queryParams: this.params.queryParams, relativeTo: this.currentActivatedRoute})

I am using Android Studio 3.0 and was facing the same problem. I add this to my gradle:

multiDexEnabled true

And it worked!

Example

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.1'
    defaultConfig {
        applicationId "com.xx.xxx"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        multiDexEnabled true //Add this
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

And clean the project.

You sure can.

The easiest way to see how you might do this is to browse to the aspx page you want to post to. Then save the source of that page as HTML. Change the action of the form on your new html page to point back to the aspx page you originally copied it from.

Add value tags to your form fields and put the data you want in there, then open the page and hit the submit button.

Try like this

var results = db.costumers.Where(X=>X.FullName.Contains(FirstName)&&(X=>X.FullName.EndsWith(LastName))
                          .Select(X=>X);

type C:\temp\test.bat>C:\temp\test.log

Am I missing something in the question or why else nobody mentioned reviver parameter of JSON.parse since 2011?

Here is simplistic code for solution that works: https://jsfiddle.net/Ldr2utrr/

function Foo()
{
   this.a = 3;
   this.b = 2;
   this.test = function() {return this.a*this.b;};
}


var fooObj = new Foo();
alert(fooObj.test() ); //Prints 6
var fooJSON = JSON.parse(`{"a":4, "b": 3}`, function(key,value){
if(key!=="") return value; //logic of course should be more complex for handling nested objects etc.
  let res = new Foo();
  res.a = value.a;
  res.b = value.b;
  return res;
});
// Here you already get Foo object back
alert(fooJSON.test() ); //Prints 12

PS: Your question is confusing: >>That's great, but how can I take that JavaScript Object and turn it into a particular JavaScript Object (i.e. with a certain prototype)? contradicts to the title, where you ask about JSON parsing, but the quoted paragraph asks about JS runtime object prototype replacement.

Another thing you could try is to upload the html to a webpage and then open the webpage in word to test Outlook.

To update NPM, this worked for me:

• Navigate in your shell to your node installation directory, eg C:\Program Files (x86)\nodejs
• run npm install npm (no -g option)

I only needed the environment variables locally to invoke my test command, here's an example setting multiple environment vars in a bash shell, and escaping the dollar sign in make.

SHELL := /bin/bash

.PHONY: test tests
test tests:
    PATH=./node_modules/.bin/:$$PATH \
    JSCOVERAGE=1 \
    nodeunit tests/

Using Guidelines you can change the positioning to be percentage based

<android.support.constraint.Guideline
android:id="@+id/guideline"
android:layout_width="1dp"
android:layout_height="wrap_content"
android:orientation="vertical"
app:layout_constraintGuide_percent="0.5"/>

You can also use this way

android:layout_width="0dp"
app:layout_constraintWidth_default="percent"
app:layout_constraintWidth_percent="0.4"

You have at least two issues in your code:

• ng-change="getScoreData(Score)

  Angular doesn't see getScoreData method that refers to defined service

• getScoreData: function (Score, callback)

  We don't need to use callback since GET returns promise. Use then instead.

Here is a working example (I used random address only for simulation):

HTML

<select ng-model="score"
        ng-change="getScoreData(score)" 
        ng-options="score as score.name for score in  scores"></select>
    <pre>{{ScoreData|json}}</pre> 

JS

var fessmodule = angular.module('myModule', ['ngResource']);

fessmodule.controller('fessCntrl', function($scope, ScoreDataService) {

    $scope.scores = [{
        name: 'Bukit Batok Street 1',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, 153 Bukit Batok Street 1&sensor=true'
    }, {
        name: 'London 8',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, London 8&sensor=true'
    }];

    $scope.getScoreData = function(score) {
        ScoreDataService.getScoreData(score).then(function(result) {
            $scope.ScoreData = result;
        }, function(result) {
            alert("Error: No data returned");
        });
    };

});

fessmodule.$inject = ['$scope', 'ScoreDataService'];

fessmodule.factory('ScoreDataService', ['$http', '$q', function($http) {

    var factory = {
        getScoreData: function(score) {
            console.log(score);
            var data = $http({
                method: 'GET',
                url: score.URL
            });


            return data;
        }
    }
    return factory;
}]);

For fun, instead of using a loop to create the extra zeros:

function zeroPad(n,length){
  var s=n+"",needed=length-s.length;
  if (needed>0) s=(Math.pow(10,needed)+"").slice(1)+s;
  return s;
}

I am mostly posting this in case someone comes along and is not aware that VB2005 and VB2008 have update utilities that convert older VB versions to it's format. Especially since no one bothered to point that fact out.

Points taken, but maintenance of this VB6 product is unavoidable. It would also be costly in man-hours to replace the Sheridan controls with native ones. Simply developing on a 32-bit machine would be a better alternative than doing that. I would like to install everything on Win7 64-bit ideally. – CJ7

Have you tried utilizing the code upgrade functionality of VB Express 2005+?

If not, 1. Make a copy of your code - folder and all. 2. Import the project into VB express 2005. This will activate the update wizard. 3. Debug and get the app running. 4. Create a new installer utilizing MS free tool. 5. You now have a 32 bit application with a 32 bit installer.

Until you do this, you will never know how difficult or hard it will be to update and modernize the program. It is quite possible that the wizard will update the Sheridan controls to the VB 2005 controls. Again, you will not know if it does and how well it does it until you try it.

Alternatively, stick with the 32 Bit versions of Windows 7 and 8. I have Windows 7 x64 and a program that will not run. However, the program will run in Windows 7 32 bit as well as Windows 8 RC 32 bit. Under Windows 8 RC 32, I was prompted to enable 16 bit emulation which I did and the program rand quite fine afterwords.

Andrey Tarasevich provides the following explanation:

2. On bytes.com

[Minor changes to formatting made. Parenthetical annotations added in square brackets []].

The whole idea of using 'do/while' version is to make a macro which will expand into a regular statement, not into a compound statement. This is done in order to make the use of function-style macros uniform with the use of ordinary functions in all contexts.

Consider the following code sketch:

if (<condition>)
  foo(a);
else
  bar(a);

where foo and bar are ordinary functions. Now imagine that you'd like to replace function foo with a macro of the above nature [named CALL_FUNCS]:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

Now, if your macro is defined in accordance with the second approach (just { and }) the code will no longer compile, because the 'true' branch of if is now represented by a compound statement. And when you put a ; after this compound statement, you finished the whole if statement, thus orphaning the else branch (hence the compilation error).

One way to correct this problem is to remember not to put ; after macro "invocations":

if (<condition>)
  CALL_FUNCS(a)
else
  bar(a);

This will compile and work as expected, but this is not uniform. The more elegant solution is to make sure that macro expand into a regular statement, not into a compound one. One way to achieve that is to define the macro as follows:

#define CALL_FUNCS(x) \
do { \
  func1(x); \
  func2(x); \
  func3(x); \
} while (0)

Now this code:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

will compile without any problems.

However, note the small but important difference between my definition of CALL_FUNCS and the first version in your message. I didn't put a ; after } while (0). Putting a ; at the end of that definition would immediately defeat the entire point of using 'do/while' and make that macro pretty much equivalent to the compound-statement version.

I don't know why the author of the code you quoted in your original message put this ; after while (0). In this form both variants are equivalent. The whole idea behind using 'do/while' version is not to include this final ; into the macro (for the reasons that I explained above).

You CAN add on click to dynamically created elements. Example below. Using a When to make sure its done. In my example, i'm grabbing a div with the class expand, adding a "click to see more" span, then using that span to hide/show the original div.

$.when($(".expand").before("<span class='clickActivate'>Click to see more</span>")).then(function(){
    $(".clickActivate").click(function(){
        $(this).next().toggle();
    })
});

You should be pointing it towards the Developer directory, not the Xcode application bundle. Run this:

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

With recent versions of Xcode, you can go to Xcode ? Preferences… ? Locations and pick one of the options for Command Line Tools to set the location.

Yes. unless, there is an ambiguity.

just

' '.join(a)

and write this output to a file.

Ranges from -9,223,372,036,854,775,808 to +9,223,372,036,854,775,807.

It will start from -9,223,372,036,854,775,808

Long.MIN_VALUE.

The simple solution is to avoid creating an array before piping to Out-File. Rule #1 of PowerShell is that the comma is a special delimiter, and the default behavior is to create an array. Concatenation is done like this.

$computer + "," + $Speed + "," + $Regcheck | out-file -filepath C:\temp\scripts\pshell\dump.txt -append -width 200

This creates an array of three items.

$computer,$Speed,$Regcheck
FYKJ
100
YES

vs. concatenation of three items separated by commas.

$computer + "," + $Speed + "," + $Regcheck
FYKJ,100,YES

I like to keep it in a single line, you can use a self calling function for this eg:

If you want to get the timestamp of +1 year in a single line

console.log(_x000D_
  (d => d.setFullYear(d.getFullYear() + 1))(new Date)_x000D_
)

If you want to get Date object with single line

console.log(_x000D_
  (d => new Date(d.getFullYear() + 1, d.getMonth(), d.getDate()))(new Date)_x000D_
)

I presume that all you are wanting is simple string concatenation:

def storescores():

   hs = open("hst.txt","a")
   hs.write(name + " ")
   hs.close() 

Alternatively, change the " " to "\n" for a newline.

0 and 7 both stand for Sunday, you can use the one you want, so writing 0-6 or 1-7 has the same result.

Also, as suggested by @Henrik, it is possible to replace numbers by shortened name of days, such as MON, THU, etc:

0 - Sun      Sunday
1 - Mon      Monday
2 - Tue      Tuesday
3 - Wed      Wednesday
4 - Thu      Thursday
5 - Fri      Friday
6 - Sat      Saturday
7 - Sun      Sunday

Graphically:

 +---------- minute (0 - 59)
 ¦ +-------- hour (0 - 23)
 ¦ ¦ +------ day of month (1 - 31)
 ¦ ¦ ¦ +---- month (1 - 12)
 ¦ ¦ ¦ ¦ +-- day of week (0 - 6 => Sunday - Saturday, or
 ¦ ¦ ¦ ¦ ¦                1 - 7 => Monday - Sunday)
 ? ? ? ? ?
 * * * * * command to be executed

Finally, if you want to specify day by day, you can separate days with commas, for example SUN,MON,THU will exectute the command only on sundays, mondays on thursdays.

I see examples with both DOM and SimpleXML, but none with the XMLWriter.

Please keep in mind that from the tests I've done, both DOM and SimpleXML are almost twice slower then the XMLWriter and for larger files you should consider using the later one.

Here's a full working example, clear and simple that meets the requirements, written with XMLWriter (I'm sure it will help other users):

// array with the key / value pairs of the information to be added (can be an array with the data fetched from db as well)
$songs = [
    'song1.mp3' => 'Track 1 - Track Title',
    'song2.mp3' => 'Track 2 - Track Title',
    'song3.mp3' => 'Track 3 - Track Title',
    'song4.mp3' => 'Track 4 - Track Title',
    'song5.mp3' => 'Track 5 - Track Title',
    'song6.mp3' => 'Track 6 - Track Title',
    'song7.mp3' => 'Track 7 - Track Title',
    'song8.mp3' => 'Track 8 - Track Title',
];

$xml = new XMLWriter();
$xml->openURI('songs.xml');
$xml->setIndent(true);
$xml->setIndentString('    ');
$xml->startDocument('1.0', 'UTF-8');
    $xml->startElement('xml');
            foreach($songs as $song => $track){
                $xml->startElement('track');
                    $xml->writeElement('path', $song);
                    $xml->writeElement('title', $track);
                $xml->endElement();
            }
    $xml->endElement();
$xml->endDocument();
$xml->flush();
unset($xml);

Pretty Diff tool was created with XML in mind. Just ensure you click the option for "markup".

Personally, I think the concatenation is the better solution. The generic implementation would be

entity shifter is
    generic (
        REGSIZE  : integer := 8);
    port(
        clk      : in  str_logic;
        Data_in  : in  std_logic;
        Data_out : out std_logic(REGSIZE-1 downto 0);
end shifter ;

architecture bhv of shifter is
    signal shift_reg : std_logic_vector(REGSIZE-1 downto 0) := (others<='0');
begin
    process (clk) begin
        if rising_edge(clk) then
            shift_reg <= shift_reg(REGSIZE-2 downto 0) & Data_in;
        end if;
    end process;
end bhv;
Data_out <= shift_reg;

Both will implement as shift registers. If you find yourself in need of more shift registers than you are willing to spend resources on (EG dividing 1000 numbers by 4) you might consider using a BRAM to store the values and a single shift register to contain "indices" that result in the correct shift of all the numbers.

hash_items = {:item => 1}
puts hash_items 
#hash_items will give you {:item => 1}

hash_items.merge!({:item => 2})
puts hash_items 
#hash_items will give you {:item => 1, :item => 2}

hash_items.merge({:item => 2})
puts hash_items 
#hash_items will give you {:item => 1, :item => 2}, but the original variable will be the same old one. 

It is possible on your restart some shards were not recovered, causing the cluster to stay red.
If you hit:
http://<yourhost>:9200/_cluster/health/?level=shards you can look for red shards.

I have had issues on restart where shards end up in a non recoverable state. My solution was to simply delete that index completely. That is not an ideal solution for everyone.

It is also nice to visualize issues like this with a plugin like:
Elasticsearch Head

Checkboxes are a control type designed for one purpose: to ensure valid entry of Boolean values.

In Access, there are two types:

1. 2-state -- can be checked or unchecked, but not Null. Values are True (checked) or False (unchecked). In Access and VBA, the value of True is -1 and the value of False is 0. For portability with environments that use 1 for True, you can always test for False or Not False, since False is the value 0 for all environments I know of.

2. 3-state -- like the 2-state, but can be Null. Clicking it cycles through True/False/Null. This is for binding to an integer field that allows Nulls. It is of no use with a Boolean field, since it can never be Null.

Minor quibble with the answers:

There is almost never a need to use the .Value property of an Access control, as it's the default property. These two are equivalent:

  ?Me!MyCheckBox.Value
  ?Me!MyCheckBox

The only gotcha here is that it's important to be careful that you don't create implicit references when testing the value of a checkbox. Instead of this:

  If Me!MyCheckBox Then

...write one of these options:

  If (Me!MyCheckBox) Then  ' forces evaluation of the control

  If Me!MyCheckBox = True Then

  If (Me!MyCheckBox = True) Then

  If (Me!MyCheckBox = Not False) Then

Likewise, when writing subroutines or functions that get values from a Boolean control, always declare your Boolean parameters as ByVal unless you actually want to manipulate the control. In that case, your parameter's data type should be an Access control and not a Boolean value. Anything else runs the risk of implicit references.

Last of all, if you set the value of a checkbox in code, you can actually set it to any number, not just 0 and -1, but any number other than 0 is treated as True (because it's Not False). While you might use that kind of thing in an HTML form, it's not proper UI design for an Access app, as there's no way for the user to be able to see what value is actually be stored in the control, which defeats the purpose of choosing it for editing your data.

Wade73's answer for decimals doesn't quite work. I've modified it to allow only a single decimal point.

declare @MyTable table(MyVar nvarchar(10));
insert into @MyTable (MyVar) 
values 
    (N'1234')
    , (N'000005')
    , (N'1,000')
    , (N'293.8457')
    , (N'x')
    , (N'+')
    , (N'293.8457.')
    , (N'......');

-- This shows that Wade73's answer allows some non-numeric values to slip through.
select * from (
    select 
        MyVar
        , case when MyVar not like N'%[^0-9.]%' then 1 else 0 end as IsNumber 
    from 
        @MyTable
) t order by IsNumber;

-- Notice the addition of "and MyVar not like N'%.%.%'".
select * from (
    select 
        MyVar
        , case when MyVar not like N'%[^0-9.]%' and MyVar not like N'%.%.%' then 1 else 0 end as IsNumber 
    from 
        @MyTable
) t 
order by IsNumber;

Take a look at itertools.chain for a fast way to treat many small lists as a single big list (or at least as a single big iterable) without copying the smaller lists:

>>> import itertools
>>> p = ['a', 'b', 'c']
>>> q = ['d', 'e', 'f']
>>> r = ['g', 'h', 'i']
>>> for x in itertools.chain(p, q, r):
        print x.upper()

For me, this is the best way.

var arrayOfNums = [1,4,5,68,9,10]

for i in 0..<arrayOfNums.count {
    print(arrayOfNums[arrayOfNums.count - i - 1])
}

What browser are you using? I entered your example and tried in both IE8 and Chrome and it validated fine when I typed in the value Sam's

    public string Name { get; set; }
 }

When I inspect the DOM using IE Developer toolbar and Chrome Developer mode it does not show any special characters.

Just from reading that i would have never understood that "$@" expands into a list of separate parameters. Whereas, "$*" is one parameter consisting of all the parameters added together.

If it still makes no sense do this.

So, the concept of a "wildcard" in Regular Expressions works a bit differently. In order to match "any character" you would use "." The "*" modifier means, match any number of times.

you could also use the builtin "join" filter (http://jinja.pocoo.org/docs/templates/#join like this:

{{ users|join(', ') }}

I know it's "a bit late" but just in case if anybody needs to do this in LINQ Method syntax (which is why I found this post initially), this would be how to do that:

var results = context.Periods
    .GroupJoin(
        context.Facts,
        period => period.id,
        fk => fk.periodid,
        (period, fact) => fact.Where(f => f.otherid == 17)
                              .Select(fact.Value)
                              .DefaultIfEmpty()
    )
    .Where(period.companyid==100)
    .SelectMany(fact=>fact).ToList();

fit() method mentioned by @Saullo Castro provides maximum likelihood estimates (MLE). The best distribution for your data is the one give you the highest can be determined by several different ways: such as

1, the one that gives you the highest log likelihood.

2, the one that gives you the smallest AIC, BIC or BICc values (see wiki: http://en.wikipedia.org/wiki/Akaike_information_criterion, basically can be viewed as log likelihood adjusted for number of parameters, as distribution with more parameters are expected to fit better)

3, the one that maximize the Bayesian posterior probability. (see wiki: http://en.wikipedia.org/wiki/Posterior_probability)

Of course, if you already have a distribution that should describe you data (based on the theories in your particular field) and want to stick to that, you will skip the step of identifying the best fit distribution.

scipy does not come with a function to calculate log likelihood (although MLE method is provided), but hard code one is easy: see Is the build-in probability density functions of `scipy.stat.distributions` slower than a user provided one?

More clarified version of above answers:

IEnumerable<IGrouping<int, ClassA>> groups = list.GroupBy(x => x.PropertyIntOfClassA);

foreach (var groupingByClassA in groups)
{
    int propertyIntOfClassA = groupingByClassA.Key;

    //iterating through values
    foreach (var classA in groupingByClassA)

I used this, seems working and is just simple JS, no framework:

Your file should start downloading in a few seconds. 
If downloading doesn't start automatically
<a id="downloadLink" href="[link to your file]">click here to get your file</a>.

<script> 
    var downloadTimeout = setTimeout(function () {
        window.location = document.getElementById('downloadLink').href;
    }, 2000);
</script>

NOTE: this starts the timeout in the moment the page is loaded.

The easier is add [0] - select first value of list with one element:

dfb = df[df['A']==5].index.values.astype(int)[0]
dfbb = df[df['A']==8].index.values.astype(int)[0]

dfb = int(df[df['A']==5].index[0])
dfbb = int(df[df['A']==8].index[0])

But if possible some values not match, error is raised, because first value not exist.

Solution is use next with iter for get default parameetr if values not matched:

dfb = next(iter(df[df['A']==5].index), 'no match')
print (dfb)
4

dfb = next(iter(df[df['A']==50].index), 'no match')
print (dfb)
no match

Then it seems need substract 1:

print (df.loc[dfb:dfbb-1,'B'])
4    0.894525
5    0.978174
6    0.859449
Name: B, dtype: float64

Another solution with boolean indexing or query:

print (df[(df['A'] >= 5) & (df['A'] < 8)])
   A         B
4  5  0.894525
5  6  0.978174
6  7  0.859449

print (df.loc[(df['A'] >= 5) & (df['A'] < 8), 'B'])
4    0.894525
5    0.978174
6    0.859449
Name: B, dtype: float64

print (df.query('A >= 5 and A < 8'))
   A         B
4  5  0.894525
5  6  0.978174
6  7  0.859449

Using java.io.File:

File f = new File(filePathString);
if(f.exists() && !f.isDirectory()) { 
    // do something
}

df.aree <- as.data.frame(t(df.aree))
colnames(df.aree) <- df.aree[1, ]
df.aree <- df.aree[-1, ]
df.aree$myfactor <- factor(row.names(df.aree))

If you're building a class library, then perhaps the users of your library would like to use your library asynchronously. I think that's the biggest reason right there.

You also don't know how your library is going to be used. Perhaps the users will be processing lots and lots of requests, and doing so asynchronously will help it perform faster and more efficient.

If you can do so simply, try not to put the burden on the users of your library trying to make the flow asynchronous when you can take care of it for them.

The only reason I wouldn't use the async version is if I were trying to support an older version of .NET that does not already have built in async support.

In Oracle 12.1 and below: 30 char (bytes, really, as has been stated).

But do not trust me; try this for yourself:

Table created.



SQL> create table I234567890123456789012345678901(my_id number);


ERROR at line 1:

Updated: as stated above, in Oracle 12.2 and later, the maximum object name length is now 128 bytes.

Here is a the list of ajax libraries comparison based on the features and support. I prefer to use fetch for only client side development or isomorphic-fetch for using in both client side and server side development.

Double click your button and use the following code :-

    //sure                
  //you have a label

Choose Database | Set Datasource Location... Select the database node (yellow-ish cylinder) of the current connection, then select the database node of the desired connection (you may need to authenticate), then click Update.

You will need to do this for the 'Subreports' nodes as well.

FYI, you can also do individual tables by selecting each individually, then choosing Update.

You could define a name for the VLOOKUP part of the formula.

1. Highlight the cell that contains this formula
2. On the Insert menu, go Name, and click Define
3. Enter a name for your variable (e.g. 'Value')
4. In the Refers To box, enter your VLOOKUP formula: =VLOOKUP(A1,B:B, 1, 0)
5. Click Add, and close the dialog
6. In your original formula, replace the VLOOKUP parts with the name you just defined: =IF( Value > 10, Value - 10, Value )

Step (1) is important here: I guess on the second row, you want Excel to use VLOOKUP(A2,B:B, 1, 0), the third row VLOOKUP(A3,B:B, 1, 0), etc. Step (4) achieves this by using relative references (A1 and B:B), not absolute references ($A$1 and $B:$B).

Note:

1. For newer Excel versions with the ribbon, go to Formulas ribbon -> Define Name. It's the same after that. Also, to use your name, you can do "Use in Formula", right under Define Name, while editing the formula, or else start typing it, and Excel will suggest the name (credits: Michael Rusch)

2. Shortened steps: 1. Right click a cell and click Define name... 2. Enter a name and the formula which you want to associate with that name/local variable 3. Use variable (credits: Jens Bodal)

originalArrayList.addAll(copyArrayList);

Please Note: When using the addAll() method to copy, the contents of both the array lists (originalArrayList and copyArrayList) refer to the same objects or contents. So if you modify any one of them the other will also reflect the same change.

If you don't wan't this then you need to copy each element from the originalArrayList to the copyArrayList, like using a for or while loop.

In my case setting typescript.disableAutomaticTypeAcquisition in Visual Studio Code to true seemed to help.

Try this:

.circle {
    height: 20px;
    width: 20px;
    padding: 5px;
    text-align: center; 
    border-radius: 50%;
    display: inline-block;
    color:#fff;
    font-size:1.1em;
    font-weight:600;
    background-color: rgba(0,0,0,0.1);
    border: 1px solid rgba(0,0,0,0.2);
}

The grid system in Bootstrap 3 requires a bit of a lateral shift in your thinking from Bootstrap 2. A column in BS2 (col-*) is NOT synonymous with a column in BS3 (col-sm-*, etc), but there is a way to achieve the same result.

Check out this update to your fiddle: http://jsfiddle.net/pjBzY/22/ (code copied below).

First of all, you don't need to specify a col for each screen size if you want 50/50 columns at all sizes. col-sm-6 applies not only to small screens, but also medium and large, meaning class="col-sm-6 col-md-6" is redundant (the benefit comes in if you want to change the column widths at different size screens, such as col-sm-6 col-md-8).

As for the margins issue, the negative margins provide a way to align blocks of text in a more flexible way than was possible in BS2. You'll notice in the jsfiddle, the text in the first column aligns visually with the text in the paragraph outside the row -- except at "xs" window sizes, where the columns aren't applied.

If you need behavior closer to what you had in BS2, where there is padding between each column and there are no visual negative margins, you will need to add an inner-div to each column. See the inner-content in my jsfiddle. Put something like this in each column, and they will behave the way old col-* elements did in BS2.

jsfiddle HTML

<div class="container">
    <p class="other-content">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse aliquam sed sem nec viverra. Phasellus fringilla metus vitae libero posuere mattis. Integer sit amet tincidunt felis. Maecenas et pharetra leo. Etiam venenatis purus et nibh laoreet blandit.</p>
    <div class="row">
        <div class="col-sm-6 my-column">
            Col 1
            <p class="inner-content">Inner content - THIS element is more synonymous with a Bootstrap 2 col-*.</p>
        </div>
        <div class="col-sm-6 my-column">
            Col 2
        </div>
    </div>
</div>

and the CSS

.row {
    border: blue 1px solid;
}
.my-column {
    background-color: green;
    padding-top: 10px;
    padding-bottom: 10px;
}
.my-column:first-child {
    background-color: red;
}

.inner-content {
    background: #eee;
    border: #999;
    border-radius: 5px;
    padding: 15px;
}

Swift 4+

NotificationCenter.default.addObserver(forName: UIApplication.userDidTakeScreenshotNotification, object: nil, queue: OperationQueue.main) { notification in
           //you can do anything you want here. 
        }

by using this observer you can find out when user takes a screenshot, but you can not prevent him.

Not free, but with the latest Office there's a very nice automation .Net API. (there has been an API for a long while but was nasty COM) You can do everything you want / need in code all while the Office app remains a hidden background process.

You need to use a group by clause.

SELECT  site_id, MAX(ts) as TIME, count(*) group by site_id

In my case I received this exception even when all parameter values were correctly supplied but the type of command was not specified :

cmd.CommandType = System.Data.CommandType.StoredProcedure;

This is obviously not the case in the question above, but exception description is not very clear in this case, so I decided to specify that.

Check possible reasons here: http://msdn.microsoft.com/en-us/library/z6c2z492(v=VS.100).aspx

EDIT:

You need to put the protocol prefix in front the address, i.e. in your case "ftp://"

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

You've got:

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

Which translates into:

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

What you actually want is:

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

Which translates into:

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

Although this is very old question i found something easier to handle this task. It is jquery plugin developed by jquery UI team called simulate. you can include it after jquery and then you can do something like

<a href="http://stackoverflow.com/"></a>
$('a').simulate('click');

works fine in chrome, firefox, opera and IE10.you can download it from https://github.com/eduardolundgren/jquery-simulate/blob/master/jquery.simulate.js

Notably, the mentioned Jackson JSON parser prefers bean_naming.

I assume that with interface you mean a C++ class with only pure virtual methods (i.e. without any code), instead with abstract class you mean a C++ class with virtual methods that can be overridden, and some code, but at least one pure virtual method that makes the class not instantiable. e.g.:

class MyInterface
{
public:
  // Empty virtual destructor for proper cleanup
  virtual ~MyInterface() {}

  virtual void Method1() = 0;
  virtual void Method2() = 0;
};


class MyAbstractClass
{
public:
  virtual ~MyAbstractClass();

  virtual void Method1();
  virtual void Method2();
  void Method3();

  virtual void Method4() = 0; // make MyAbstractClass not instantiable
};

In Windows programming, interfaces are fundamental in COM. In fact, a COM component exports only interfaces (i.e. pointers to v-tables, i.e. pointers to set of function pointers). This helps defining an ABI (Application Binary Interface) that makes it possible to e.g. build a COM component in C++ and use it in Visual Basic, or build a COM component in C and use it in C++, or build a COM component with Visual C++ version X and use it with Visual C++ version Y. In other words, with interfaces you have high decoupling between client code and server code.

Moreover, when you want to build DLL's with a C++ object-oriented interface (instead of pure C DLL's), as described in this article, it's better to export interfaces (the "mature approach") instead of C++ classes (this is basically what COM does, but without the burden of COM infrastructure).

I'd use an interface if I want to define a set of rules using which a component can be programmed, without specifying a concrete particular behavior. Classes that implement this interface will provide some concrete behavior themselves.

Instead, I'd use an abstract class when I want to provide some default infrastructure code and behavior, and make it possible to client code to derive from this abstract class, overriding the pure virtual methods with some custom code, and complete this behavior with custom code. Think for example of an infrastructure for an OpenGL application. You can define an abstract class that initializes OpenGL, sets up the window environment, etc. and then you can derive from this class and implement custom code for e.g. the rendering process and handling user input:

// Abstract class for an OpenGL app.
// Creates rendering window, initializes OpenGL; 
// client code must derive from it 
// and implement rendering and user input.
class OpenGLApp
{
public:
  OpenGLApp();
  virtual ~OpenGLApp();
  ...

  // Run the app    
  void Run();


  // <---- This behavior must be implemented by the client ---->

  // Rendering
  virtual void Render() = 0;

  // Handle user input
  // (returns false to quit, true to continue looping)
  virtual bool HandleInput() = 0;

  // <--------------------------------------------------------->


private:
  //
  // Some infrastructure code
  //
  ... 
  void CreateRenderingWindow();
  void CreateOpenGLContext();
  void SwapBuffers();
};


class MyOpenGLDemo : public OpenGLApp
{
public:
  MyOpenGLDemo();
  virtual ~MyOpenGLDemo();

  // Rendering
  virtual void Render();  // implements rendering code

  // Handle user input
  virtual bool HandleInput(); // implements user input handling


  //  ... some other stuff
};

Use Windows Job Objects. Jobs are like process groups and can limit memory usage and process priority.

To sum it all up, the correct answer is :

select * from db where Date >= '20100401'  (Format of date yyyymmdd)

This will avoid any problem with other language systems and will use the index.

simple synchronous way with node:

let fs = require('fs')

let filename = "your-file.something"

let content = fs.readFileSync(process.cwd() + "/" + filename).toString()

console.log(content)

Assuming a as double and we need a rounded number with no decimal place . Use Math.round() function.
This goes as my solution .

double a = 0.99999;
int rounded_a = (int)Math.round(a);
System.out.println("a:"+rounded_a );

Output : 
a:1

My approach is to store the PID to a file in /tmp, and to find the right process using the -S option for ssh. That might be a misuse but works for me.

#!/bin/bash

TARGET_REDIS=${1:-redis.someserver.com}
PROXY="proxy.somewhere.com"

LOCAL_PORT=${2:-6379}

if [ "$1" == "stop" ] ; then
    kill `cat /tmp/sshTunel${LOCAL_PORT}-pid`
    exit
fi

set -x

ssh -f -i ~/.ssh/aws.pem centos@$PROXY -L $LOCAL_PORT:$TARGET_REDIS:6379 -N -S /tmp/sshTunel$LOCAL_PORT  ## AWS DocService dev, DNS alias
# SSH_PID=$! ## Only works with &
SSH_PID=`ps aux | grep sshTunel${LOCAL_PORT} | grep -v grep | awk '{print $2}'`
echo $SSH_PID > /tmp/sshTunel${LOCAL_PORT}-pid

Better approach might be to query for the SSH_PID right before killing it, since the file might be stale and it would kill a wrong process.

The simplest way is to make String conform to Error:

extension String: Error {}

Then you can just throw a string:

throw "Some Error"

To make the string itself be the localizedString of the error you can instead extend LocalizedError:

extension String: LocalizedError {
    public var errorDescription: String? { return self }
}

select 
{
    -webkit-appearance: none;
}

If you need to you can also add an image that contains the arrow as part of the background.

You have several options

integer(3)
numeric(3)
rep(0, 3)
rep(0L, 3)

it depends what sort of t-test you want to do (one sided or two sided dependent or independent) but it should be as simple as:

from scipy.stats import ttest_ind

cat1 = my_data[my_data['Category']=='cat1']
cat2 = my_data[my_data['Category']=='cat2']

ttest_ind(cat1['values'], cat2['values'])
>>> (1.4927289925706944, 0.16970867501294376)

it returns a tuple with the t-statistic & the p-value

see here for other t-tests http://docs.scipy.org/doc/scipy/reference/stats.html

To get all divs under 'container', use the following:

$(".container>div")  //or
$(".container").children("div");

You can stipulate a specific #id instead of div to get a particular one.

You say you want a div with an 'undefined' id. if I understand you right, the following would achieve this:

$(".container>div[id=]")

Note also that "key" does not necessarily mean primary key. Something like this will work:

CREATE TABLE book (
    isbn             BIGINT NOT NULL PRIMARY KEY,
    id               INT    NOT NULL AUTO_INCREMENT,
    accepted_terms   BIT(1) NOT NULL,
    accepted_privacy BIT(1) NOT NULL,
    INDEX(id)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

This is a contrived example and probably not the best idea, but it can be very useful in certain cases.

Decimal is for exact values. Double is for approximate values.

^{Why another answer? I attempted to expand my previous answer by adding details on how to support JSR-250 annotations. However the original answer became the way too long and exceeded the maximum length of 30,000 characters. So I moved the whole authorization details to this answer, keeping the other answer focused on performing authentication and issuing tokens.}

Supporting role-based authorization with the @Secured annotation

Besides authentication flow shown in the other answer, role-based authorization can be supported in the REST endpoints.

Create an enumeration and define the roles according to your needs:

public enum Role {
    ROLE_1,
    ROLE_2,
    ROLE_3
}

Change the @Secured name binding annotation created before to support roles:

@NameBinding
@Retention(RUNTIME)
@Target({TYPE, METHOD})
public @interface Secured {
    Role[] value() default {};
}

And then annotate the resource classes and methods with @Secured to perform the authorization. The method annotations will override the class annotations:

@Path("/example")
@Secured({Role.ROLE_1})
public class ExampleResource {

    @GET
    @Path("{id}")
    @Produces(MediaType.APPLICATION_JSON)
    public Response myMethod(@PathParam("id") Long id) {
        // This method is not annotated with @Secured
        // But it's declared within a class annotated with @Secured({Role.ROLE_1})
        // So it only can be executed by the users who have the ROLE_1 role
        ...
    }

    @DELETE
    @Path("{id}")    
    @Produces(MediaType.APPLICATION_JSON)
    @Secured({Role.ROLE_1, Role.ROLE_2})
    public Response myOtherMethod(@PathParam("id") Long id) {
        // This method is annotated with @Secured({Role.ROLE_1, Role.ROLE_2})
        // The method annotation overrides the class annotation
        // So it only can be executed by the users who have the ROLE_1 or ROLE_2 roles
        ...
    }
}

Create a filter with the AUTHORIZATION priority, which is executed after the AUTHENTICATION priority filter defined previously.

The ResourceInfo can be used to get the resource Method and resource Class that will handle the request and then extract the @Secured annotations from them:

@Secured
@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {

    @Context
    private ResourceInfo resourceInfo;

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {

        // Get the resource class which matches with the requested URL
        // Extract the roles declared by it
        Class<?> resourceClass = resourceInfo.getResourceClass();
        List<Role> classRoles = extractRoles(resourceClass);

        // Get the resource method which matches with the requested URL
        // Extract the roles declared by it
        Method resourceMethod = resourceInfo.getResourceMethod();
        List<Role> methodRoles = extractRoles(resourceMethod);

        try {

            // Check if the user is allowed to execute the method
            // The method annotations override the class annotations
            if (methodRoles.isEmpty()) {
                checkPermissions(classRoles);
            } else {
                checkPermissions(methodRoles);
            }

        } catch (Exception e) {
            requestContext.abortWith(
                Response.status(Response.Status.FORBIDDEN).build());
        }
    }

    // Extract the roles from the annotated element
    private List<Role> extractRoles(AnnotatedElement annotatedElement) {
        if (annotatedElement == null) {
            return new ArrayList<Role>();
        } else {
            Secured secured = annotatedElement.getAnnotation(Secured.class);
            if (secured == null) {
                return new ArrayList<Role>();
            } else {
                Role[] allowedRoles = secured.value();
                return Arrays.asList(allowedRoles);
            }
        }
    }

    private void checkPermissions(List<Role> allowedRoles) throws Exception {
        // Check if the user contains one of the allowed roles
        // Throw an Exception if the user has not permission to execute the method
    }
}

If the user has no permission to execute the operation, the request is aborted with a 403 (Forbidden).

To know the user who is performing the request, see my previous answer. You can get it from the SecurityContext (which should be already set in the ContainerRequestContext) or inject it using CDI, depending on the approach you go for.

If a @Secured annotation has no roles declared, you can assume all authenticated users can access that endpoint, disregarding the roles the users have.

Supporting role-based authorization with JSR-250 annotations

Alternatively to defining the roles in the @Secured annotation as shown above, you could consider JSR-250 annotations such as @RolesAllowed, @PermitAll and @DenyAll.

JAX-RS doesn't support such annotations out-of-the-box, but it could be achieved with a filter. Here are a few considerations to keep in mind if you want to support all of them:

• @DenyAll on the method takes precedence over @RolesAllowed and @PermitAll on the class.
• @RolesAllowed on the method takes precedence over @PermitAll on the class.
• @PermitAll on the method takes precedence over @RolesAllowed on the class.
• @DenyAll can't be attached to classes.
• @RolesAllowed on the class takes precedence over @PermitAll on the class.

So an authorization filter that checks JSR-250 annotations could be like:

@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {

    @Context
    private ResourceInfo resourceInfo;

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {

        Method method = resourceInfo.getResourceMethod();

        // @DenyAll on the method takes precedence over @RolesAllowed and @PermitAll
        if (method.isAnnotationPresent(DenyAll.class)) {
            refuseRequest();
        }

        // @RolesAllowed on the method takes precedence over @PermitAll
        RolesAllowed rolesAllowed = method.getAnnotation(RolesAllowed.class);
        if (rolesAllowed != null) {
            performAuthorization(rolesAllowed.value(), requestContext);
            return;
        }

        // @PermitAll on the method takes precedence over @RolesAllowed on the class
        if (method.isAnnotationPresent(PermitAll.class)) {
            // Do nothing
            return;
        }

        // @DenyAll can't be attached to classes

        // @RolesAllowed on the class takes precedence over @PermitAll on the class
        rolesAllowed = 
            resourceInfo.getResourceClass().getAnnotation(RolesAllowed.class);
        if (rolesAllowed != null) {
            performAuthorization(rolesAllowed.value(), requestContext);
        }

        // @PermitAll on the class
        if (resourceInfo.getResourceClass().isAnnotationPresent(PermitAll.class)) {
            // Do nothing
            return;
        }

        // Authentication is required for non-annotated methods
        if (!isAuthenticated(requestContext)) {
            refuseRequest();
        }
    }

    /**
     * Perform authorization based on roles.
     *
     * @param rolesAllowed
     * @param requestContext
     */
    private void performAuthorization(String[] rolesAllowed, 
                                      ContainerRequestContext requestContext) {

        if (rolesAllowed.length > 0 && !isAuthenticated(requestContext)) {
            refuseRequest();
        }

        for (final String role : rolesAllowed) {
            if (requestContext.getSecurityContext().isUserInRole(role)) {
                return;
            }
        }

        refuseRequest();
    }

    /**
     * Check if the user is authenticated.
     *
     * @param requestContext
     * @return
     */
    private boolean isAuthenticated(final ContainerRequestContext requestContext) {
        // Return true if the user is authenticated or false otherwise
        // An implementation could be like:
        // return requestContext.getSecurityContext().getUserPrincipal() != null;
    }

    /**
     * Refuse the request.
     */
    private void refuseRequest() {
        throw new AccessDeniedException(
            "You don't have permissions to perform this action.");
    }
}

^{Note: The above implementation is based on the Jersey RolesAllowedDynamicFeature. If you use Jersey, you don't need to write your own filter, just use the existing implementation.}

try this

var configuration = WebConfigurationManager.OpenWebConfiguration("~");
var section = (ConnectionStringsSection)configuration.GetSection("connectionStrings");
section.ConnectionStrings["MyConnectionString"].ConnectionString = "Data Source=...";
configuration.Save();

I'm quite ashamed that there are so many incorrect or undisclosed partial applicability.

The easiest way to do this is through Chrome or Opera (my examples will use Chrome) using the Console. Enter the following code into the console (generally in 1 line):

var l = document.getElementById('testLink');
for(var i=0; i<5; i++){
  l.click();
}

This will generate the required result

Do you need the pipe?

echo -ne "$MENU"
read NUMBER

So for us it was we were trying to send too large of an object through our AIDL interface to a remote service. The transaction size cannot exceed 1MB. The request is broken down into separate chunks of 512KB and sent one at a time through the interface. A brutal solution I know but hey - its Android :(

If you want to avoid inline script, you can simply listen for a click event on the radio. This can be achieved with plain Javascript by listening to a click event on

for (var radioCounter = 0 ; radioCounter < document.getElementsByName('myRadios').length; radioCounter++) {
      document.getElementsByName('myRadios')[radioCounter].onclick = function() {
        //VALUE OF THE CLICKED RADIO ELEMENT
        console.log('this : ',this.value);
      }
}

I totally agree, the restrictions are too strong. Using a static helper method (as Tom Hawtin - tackline suggested) or shoving all "pre-super() computations" into a single expression in the parameter is not always possible, e.g.:

class Sup {
    public Sup(final int x_) { 
        //cheap constructor 
    }
    public Sup(final Sup sup_) { 
        //expensive copy constructor 
    }
}

class Sub extends Sup {
    private int x;
    public Sub(final Sub aSub) {
        /* for aSub with aSub.x == 0, 
         * the expensive copy constructor is unnecessary:
         */

         /* if (aSub.x == 0) { 
          *    super(0);
          * } else {
          *    super(aSub);
          * } 
          * above gives error since if-construct before super() is not allowed.
          */

        /* super((aSub.x == 0) ? 0 : aSub); 
         * above gives error since the ?-operator's type is Object
         */

        super(aSub); // much slower :(  

        // further initialization of aSub
    }
}

Using an "object not yet constructed" exception, as Carson Myers suggested, would help, but checking this during each object construction would slow down execution. I would favor a Java compiler that makes a better differentiation (instead of inconsequently forbidding an if-statement but allowing the ?-operator within the parameter), even if this complicates the language spec.

div {_x000D_
    display: table-cell;_x000D_
    vertical-align: middle;_x000D_
    height: 50px;_x000D_
    border: 1px solid red;_x000D_
}

<div>_x000D_
    <label for='name'>Name:</label>_x000D_
    <input type='text' id='name' />_x000D_
</div>

The advantages of this method is that you can change the height of the div, change the height of the text field and change the font size and everything will always stay in the middle.

The previous answers seem all to be a little confusing or incomplete, so here is a table of the differences...

+----------------+-----------------+----------------+----------------+
|    Command     | Displays Output | Can Get Output | Gets Exit Code |
+----------------+-----------------+----------------+----------------+
| system()       | Yes (as text)   | Last line only | Yes            |
| passthru()     | Yes (raw)       | No             | Yes            |
| exec()         | No              | Yes (array)    | Yes            |
| shell_exec()   | No              | Yes (string)   | No             |
| backticks (``) | No              | Yes (string)   | No             |
+----------------+-----------------+----------------+----------------+

• "Displays Output" means it streams the output to the browser (or command line output if running from a command line).
• "Can Get Output" means you can get the output of the command and assign it to a PHP variable.
• The "exit code" is a special value returned by the command (also called the "return status"). Zero usually means it was successful, other values are usually error codes.

Other misc things to be aware of:

• The shell_exec() and the backticks operator do the same thing.
• There are also proc_open() and popen() which allow you to interactively read/write streams with an executing command.
• Add "2>&1" to the command string if you also want to capture/display error messages.
• Use escapeshellcmd() to escape command arguments that may contain problem characters.
• If passing an $output variable to exec() to store the output, if $output isn't empty, it will append the new output to it. So you may need to unset($output) first.

If you're experimenting with Metal rendering & you're extracting the CGImage generated by imageByApplyingAlpha in the first reply, you may end up with a Metal rendering that's larger than you expect. While experimenting with Metal, you may want to change one line of code in imageByApplyingAlpha:

    UIGraphicsBeginImageContextWithOptions (self.size, NO, 1.0f);
//  UIGraphicsBeginImageContextWithOptions (self.size, NO, 0.0f);

If you're using a device with a scale factor of 3.0, like the iPhone 11 Pro Max, the 0.0 scale factor shown above will give you an CGImage that's three times larger than you're expecting. Changing the scale factor to 1.0 should avoid any scaling.

Hopefully, this reply will save beginners a lot of aggravation.

well, why don't you (get rid of sidebar and) squeeze the table so it is without show/hide effect? It looks odd to me now. The table is too robust.
Otherwise I think scunliffe's suggestion should do it. Or if you wish, you can just set the exact width of table and set either percentage or pixel width for table cells.

Use this,

var url = req.headers.host + '/' + req.url;

For all newbie guys searching for some hint about currency conversion, take a look at this link. Datavoila

It helped med a lot regarding my own project in C#. Just in case the site disappears, I'll add the code below. Just add the below steps to your own project. Sorry about the formatting.

const string fromCurrency = "USD";
const string toCurrency = "EUR";
const double amount = 49.95;
// For other currency symbols see http://finance.yahoo.com/currency-converter/
// Clear the output editor //optional use, AFAIK
Output.Clear();

// Construct URL to query the Yahoo! Finance API
const string urlPattern = "http://finance.yahoo.com/d/quotes.csv?s={0}{1}=X&f=l1";
string url = String.Format(urlPattern, fromCurrency, toCurrency);

// Get response as string
string response = new WebClient().DownloadString(url);

// Convert string to number
double exchangeRate =
    double.Parse(response, System.Globalization.CultureInfo.InvariantCulture);

// Output the result
Output.Text = String.Format("{0} {1} = {2} {3}",
                            amount, fromCurrency,
                            amount * exchangeRate, toCurrency);

I was also having this issue of "You have mail" coming up every time I started Terminal.

What I discovered is this.

Something I'd installed (not entirely sure what, but possibly a script or something associated with an Alfred Workflow [at a guess]) made a change to the OS X system to start presenting Terminal bash notifications. Prior to that, it appears Wordpress had attempted to use the Local Mail system to send a message. The message bounced, due to it having an invalid Recipient address. The bounced message then ended up in the local system mail inbox. So Terminal (bash) was then notifying me that "You have mail".

You can access the mail by simply using the command

mail

This launches you into Mail, and it will right away show you a list of messages that are stored there. If you want to see the content of the first message, use

t

This will show you the content of the first message, in full. You'll need to scroll down through the message to view it all, by hitting the down-arrow key.

If you want to jump to the end of the message, use the

spacebar

If you want to abort viewing the message, use

q 

To view the next message in the queue use

n

... assuming there's more than one message.

NOTE: You need to use these commands at the mail ? command prompt. They won't work whilst you are in the process of viewing a message. Hitting n whilst viewing a message will just cause an error message related to regular expressions. So, if in the midst of viewing a message, hit q to quit from that, or hit spacebar to jump to the end of the message, and then at the ? prompt, hit n.

Viewing the content of the messages in this way may help you identify what attempted to send the message(s).

You can also view a specific message by just inputting its number at the ? prompt. 3, for instance, will show you the content of the third message (if there are that many in there).

Use the d command (at the ? command prompt )

d [message number]

To delete each message when you are done looking at them. For example, d 2 will delete message number 2. Or you can delete a list of messages, such as d 1 2 5 7. Or you can delete a range of messages with (for example), d 3-10. You can find the message numbers in the list of messages mail shows you.

To delete all the messages, from the mail prompt (?) use the command d *.

As per a comment on this post, you will need to use q to quit mail, which also saves any changes.

If you'd like to see the mail all in one output, use this command at the bash prompt (i.e. not from within mail, but from your regular command prompt):

cat /var/mail/<username>

And, if you wish to delete the emails all in one hit, use this command

sudo rm /var/mail/<username>

In my particular case, there were a number of messages. It looks like the one was a returned message that bounced. It was sent by a local Wordpress installation. It was a notification for when user "Admin" (me) changed its password. Two additional messages where there. Both seemed to be to the same incident.

What I don't know, and can't answer for you either, is WHY I only recently started seeing this mail notification each time I open Terminal. The mails were generated a couple of months ago, and yet I only noticed this "you have mail" appearing in the last few weeks. I suspect it's the result of something a workflow I installed in Alfred, and that workflow using Terminal bash to provide notifications... or something along those lines.

Simply deleting the messages

If you have no interest in determining the source of the messages, and just wish to get rid of them, it may be easier to do so without using the mail command (which can be somewhat fiddly). As pointed out by a few other people, you can use this command instead:

sudo rm /var/mail/YOURUSERNAME

There is a method of UIScrollViewDelegate which can be used to detect (or better to say 'predict') when scrolling has really finished:

func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>)

of UIScrollViewDelegate which can be used to detect (or better to say 'predict') when scrolling has really finished.

In my case I used it with horizontal scrolling as following (in Swift 3):

func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
    perform(#selector(self.actionOnFinishedScrolling), with: nil, afterDelay: Double(velocity.x))
}
func actionOnFinishedScrolling() {
    print("scrolling is finished")
    // do what you need
}

Use router.back() directly to go back/route-back programmatic on vue-router.

The best approach (IMO) is to use skip and limit BUT within a limited collections or documents.

To make the query within limited documents, we can use specific index like index on a DATE type field. See that below

let page = ctx.request.body.page || 1
let size = ctx.request.body.size || 10
let DATE_FROM = ctx.request.body.date_from
let DATE_TO = ctx.request.body.date_to

var start = (parseInt(page) - 1) * parseInt(size)

let result = await Model.find({ created_at: { $lte: DATE_FROM, $gte: DATE_TO } })
    .sort({ _id: -1 })
    .select('<fields>')
    .skip( start )
    .limit( size )        
    .exec(callback)

There is a mistake in your insert statement chage it to below and try : String sql = "insert into table_name values ('" + Col1 +"','" + Col2 + "','" + Col3 + "')";

For what it's worth, here's another version which supports odd length strings, without resorting to string concatenation.

public static byte[] hexStringToByteArray(String input) {
    int len = input.length();

    if (len == 0) {
        return new byte[] {};
    }

    byte[] data;
    int startIdx;
    if (len % 2 != 0) {
        data = new byte[(len / 2) + 1];
        data[0] = (byte) Character.digit(input.charAt(0), 16);
        startIdx = 1;
    } else {
        data = new byte[len / 2];
        startIdx = 0;
    }

    for (int i = startIdx; i < len; i += 2) {
        data[(i + 1) / 2] = (byte) ((Character.digit(input.charAt(i), 16) << 4)
                + Character.digit(input.charAt(i+1), 16));
    }
    return data;
}

I've tested this using the following powershell script and using (,) between the addresses. It worked for me!

$EmailFrom = "<[email protected]>";
$EmailPassword = "<password>";
$EmailTo = "<[email protected]>,<[email protected]>";
$SMTPServer = "<smtp.server.com>";
$SMTPPort = <port>;
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer,$SMTPPort);
$SMTPClient.EnableSsl = $true;
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($EmailFrom, $EmailPassword);
$Subject = "Notification from XYZ";
$Body = "this is a notification from XYZ Notifications..";
$SMTPClient.Send($EmailFrom, $EmailTo, $Subject, $Body);

<asp:FileUpload ID="FileUploadExcel" ClientIDMode="Static" runat="server" />
<asp:Button ID="btnUpload" ClientIDMode="Static" runat="server" Text="Upload Excel File" />

.

$('#btnUpload').click(function () {
    var uploadpath = $('#FileUploadExcel').val();
    var fileExtension = uploadpath.substring(uploadpath.lastIndexOf(".") + 1, uploadpath.length);

    if ($('#FileUploadExcel').val().length == 0) {
        // write error message
        return false;
    }

    if (fileExtension == "xls" || fileExtension == "xlsx") {
        //write code for success
    }
    else {
        //error code - select only excel files
        return false;
    }

});

From psql's help (\?):

\o [FILE] send all query results to file or |pipe

The sequence of commands will look like this:

[wist@scifres ~]$ psql db
Welcome to psql 8.3.6, the PostgreSQL interactive terminal

db=>\o out.txt
db=>\dt
db=>\q

Yes and no. Only one application can actively listen on a port. But that application can bequeath its connection to another process. So you could have multiple processes working on the same port.

I know this is a very old question and the problem is marked as fixed. However, if someone with a case like mine where the table have trigger for data logging on update events, this will cause problem. Both the columns will get the update and log will make useless entries. The way I did

IF (CONDITION) IS TRUE
BEGIN
    UPDATE table SET columnx = 25
END
ELSE
BEGIN
    UPDATE table SET columny = 25
END

Now this have another benefit that it does not have unnecessary writes on the table like the above solutions.

Your target triplet indicates that your compiler is configured for the hard-float ABI. This means that the libgcc library will also be hardfp. The error message indicates that at least part of your system is using soft-float ABI.

If the compiler has multilib enabled (you can tell with -print-multi-lib) then you can use -mfloat-abi=softfp, but if not then that option won't help you much: gcc will happily generate softfp code, but then there'll be no compatible libgcc to link against.

Basically, hardfp and softfp are just not compatible. You need to get your whole system configured one way or the other.

EDIT: some distros are, or will be, "multiarch". If you have one of those then it's possible to install both ABIs at once, but that's done by doubling everything up -- the compatibility issues still exist.

The problem was that you needed to add " ' ;" at the end.

See http://ruby-doc.org/core/classes/Range.html#M000695 for the full API.

Basically you use the step() method. For example:

(10..100).step(10) do |n|
    # n = 10
    # n = 20
    # n = 30
    # ...
end

preg_replace('/[^a-zA-Z0-9\s]/', '',$string) this is using for removing special character only rather than space between the strings.

work for me...

<android.support.v7.widget.Toolbar
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/toolBar"
        android:background="@color/colorGreen"
        app:title="Title"
        app:titleTextColor="@color/colorBlack"
        app:navigationIcon="@drawable/ic_action_back"/>

You could do something like this:

<body>

<textarea id="txtArea" onkeypress="onTestChange();"></textarea>

<script>
function onTestChange() {
    var key = window.event.keyCode;

    // If the user has pressed enter
    if (key === 13) {
        document.getElementById("txtArea").value = document.getElementById("txtArea").value + "\n*";
        return false;
    }
    else {
        return true;
    }
}
</script>

</body>

Although the new line character feed from pressing enter will still be there, but its a start to getting what you want.

Starting from this:

>>> lst = [1, 2, 3]
>>> print('\n'.join('{}: {}'.format(*k) for k in enumerate(lst)))
0: 1
1: 2
2: 3

You can get rid of the join by passing \n as a separator to print

>>> print(*('{}: {}'.format(*k) for k in enumerate(lst)), sep="\n")
0: 1
1: 2
2: 3

Now you see you could use map, but you'll need to change the format string (yuck!)

>>> print(*(map('{0[0]}: {0[1]}'.format, enumerate(lst))), sep="\n")
0: 1
1: 2
2: 3

or pass 2 sequences to map. A separate counter and no longer enumerate lst

>>> from itertools import count
>>> print(*(map('{}: {}'.format, count(), lst)), sep="\n")
0: 1
1: 2
2: 3

You have two ways to fix this. The preferred way is to use:

string answer;

(instead of char). The other possible way to fix it is:

if (answer == 'y') ...

(note single quotes instead of double, representing a char constant).

<?php
$first = reset($arr_nav); // Get the first element
$last  = end($arr_nav);   // Get the last element
// Ensure that we have a first element and that it's an array
if(is_array($first)) { 
   $first['class'] = 'first';
}
// Ensure we have a last element and that it differs from the first
if(is_array($last) && $last !== $first) {
   $last['class'] = 'last';
}

Now you could just echo the class inside you html-generator. Would probably need some kind of check to ensure that the class is set, or provide a default empty class to the array.

The map() function is there to apply the same procedure to every item in an iterable data structure, like lists, generators, strings, and other stuff.

Let's look at an example: map() can iterate over every item in a list and apply a function to each item, than it will return (give you back) the new list.

Imagine you have a function that takes a number, adds 1 to that number and returns it:

def add_one(num):
  new_num = num + 1
  return new_num

You also have a list of numbers:

my_list = [1, 3, 6, 7, 8, 10]

if you want to increment every number in the list, you can do the following:

>>> map(add_one, my_list)
[2, 4, 7, 8, 9, 11]

Note: At minimum map() needs two arguments. First a function name and second something like a list.

Let's see some other cool things map() can do. map() can take multiple iterables (lists, strings, etc.) and pass an element from each iterable to a function as an argument.

We have three lists:

list_one = [1, 2, 3, 4, 5]
list_two = [11, 12, 13, 14, 15]
list_three = [21, 22, 23, 24, 25]

map() can make you a new list that holds the addition of elements at a specific index.

Now remember map(), needs a function. This time we'll use the builtin sum() function. Running map() gives the following result:

>>> map(sum, list_one, list_two, list_three)
[33, 36, 39, 42, 45]

REMEMBER:
In Python 2 map(), will iterate (go through the elements of the lists) according to the longest list, and pass None to the function for the shorter lists, so your function should look for None and handle them, otherwise you will get errors. In Python 3 map() will stop after finishing with the shortest list. Also, in Python 3, map() returns an iterator, not a list.

write a button tag and on click function

var x = document.getElementById('codeRefer').innerHTML;
  document.getElementById('codeRefer').innerHTML = x;

write this all in onclick function

1. checkout this system variable local_infile is on

 SHOW VARIABLES LIKE 'local_infile';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| local_infile  | ON    |
+---------------+-------+

If not, restart mysqld with:

sudo ./mysqld_safe --local-infile

2. change you csv file to /tmp folder so that it mysqls can read it.

3. import to db

mysql> LOAD DATA INFILE '/tmp/a.csv'  INTO TABLE table_a  FIELDS TERMINATED BY ','  ENCLOSED BY '"' LINES TERMINATED BY '\n' IGNORE 1 ROWS;
Query OK, 18 rows affected (0.17 sec)
Records: 18  Deleted: 0  Skipped: 0  Warnings: 0

Here is the way I do that. I open multiple ZIP but also other kind of data (I export projet in PDF and at same time many ZIPs with document).

I just copy past part of my code. The call from a button in a list:

$url_pdf = "pdf.php?id=7";
$url_zip1 = "zip.php?id=8";
$url_zip2 = "zip.php?id=9";
$btn_pdf = "<a href=\"javascript:;\" onClick=\"return open_multiple('','".$url_pdf.",".$url_zip1.",".$url_zip2."');\">\n";
$btn_pdf .= "<img src=\"../../../images/icones/pdf.png\" alt=\"Ver\">\n";
$btn_pdf .= "</a>\n"

So a basic call to a JS routine (Vanilla rules!). here is the JS routine:

 function open_multiple(base,url_publication)
 {
     // URL of pages to open are coma separated
     tab_url = url_publication.split(",");
     var nb = tab_url.length;
     // Loop against URL    
     for (var x = 0; x < nb; x++)
     {
        window.open(tab_url[x]);
      }

     // Base is the dest of the caller page as
     // sometimes I need it to refresh
     if (base != "")
      {
        window.location.href  = base;
      }
   }

The trick is to NOT give the direct link of the ZIP file but to send it to the browser. Like this:

  $type_mime = "application/zip, application/x-compressed-zip";
 $the_mime = "Content-type: ".$type_mime;
 $tdoc_size = filesize ($the_zip_path);
 $the_length = "Content-Length: " . $tdoc_size;
 $tdoc_nom = "Pesquisa.zip";
 $the_content_disposition = "Content-Disposition: attachment; filename=\"".$tdoc_nom."\"";

  header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
  header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");   // Date in the past
  header($the_mime);
  header($the_length);
  header($the_content_disposition);

  // Clear the cache or some "sh..." will be added
  ob_clean();
  flush();
  readfile($the_zip_path);
  exit();
