You can use the SOUNDEX and related DIFFERENCE function in SQL Server to find similar names. The reference on MSDN is here.

You are printing the enum object. Use the .value attribute if you wanted just to print that:

print(D.x.value)

See the Programmatic access to enumeration members and their attributes section:

If you have an enum member and need its name or value:

>>>
>>> member = Color.red
>>> member.name
'red'
>>> member.value
1

You could add a __str__ method to your enum, if all you wanted was to provide a custom string representation:

class D(Enum):
    def __str__(self):
        return str(self.value)

    x = 1
    y = 2

Demo:

>>> from enum import Enum
>>> class D(Enum):
...     def __str__(self):
...         return str(self.value)
...     x = 1
...     y = 2
... 
>>> D.x
<D.x: 1>
>>> print(D.x)
1

well, I actually just saved and closed the project and restarted VS Express 2013 in windows 8 and that sorted my problem.

From the python command prompt:

import scipy
print scipy.__version__

In python 3 you'll need to change it to:

print (scipy.__version__)

It is possible to rename all tables within a database to be under another database without having to do a full dump and restore.

DROP PROCEDURE IF EXISTS mysql.rename_db;
DELIMITER ||
CREATE PROCEDURE mysql.rename_db(IN old_db VARCHAR(100), IN new_db VARCHAR(100))
BEGIN
SELECT CONCAT('CREATE DATABASE ', new_db, ';') `# create new database`;
SELECT CONCAT('RENAME TABLE `', old_db, '`.`', table_name, '` TO `', new_db, '`.`', table_name, '`;') `# alter table` FROM information_schema.tables WHERE table_schema = old_db;
SELECT CONCAT('DROP DATABASE `', old_db, '`;') `# drop old database`;
END||
DELIMITER ;

$ time mysql -uroot -e "call mysql.rename_db('db1', 'db2');" | mysql -uroot

However any triggers in the target db will not be happy. You'll need to drop them first then recreate them after the rename.

mysql -uroot -e "call mysql.rename_db('test', 'blah2');" | mysql -uroot
ERROR 1435 (HY000) at line 4: Trigger in wrong schema

Change all "es6" and "es7" to "es" in your polyfills.ts and polyfills.ts

As mentioned here, there are possibilities to get the size of primitive types through their wrappers.

e.g. for a long this could be Long.SIZE / Byte.SIZE from java 1.5 (as mentioned by zeodtr already) or Long.BYTES as from java 8

#include<boost/range/numeric.hpp>
int sum = boost::accumulate(vector, 0);

Right click in Project / Clean

That always works for me

We can do it with another approach too, Like first of all get the hash value from js and call the ajax using that parameter and can do whatever we want

Borrowed from @Deena above, that function modification for labels is more versatile than you might have thought. For example, I had a ggplot where the denominator of counted variables was 140. I used her example thus:

scale_y_continuous(labels = function(x) paste0(round(x/140*100,1), "%"), breaks = seq(0, 140, 35))

This allowed me to get my percentages on the 140 denominator, and then break the scale at 25% increments rather than the weird numbers it defaulted to. The key here is that the scale breaks are still set by the original count, not by your percentages. Therefore the breaks must be from zero to the denominator value, with the third argument in "breaks" being the denominator divided by however many label breaks you want (e.g. 140 * 0.25 = 35).

You could use the basic HTML player or you can make your own custom one. Just saying. If you want you can refer to ... https://codepen.io/search/pens?q=video+player and have a scroll through or not. It is to to you.

I don't think it is possible, because function definitions do not match in your example.

Your lambda expression is evaluated exactly as

void action() { }

whereas your declaration looks like

Void action(Void v) {
    //must return Void type.
}

as an example, if you have following interface

public interface VoidInterface {
    public Void action(Void v);
}

the only kind of function (while instantiating) that will be compatibile looks like

new VoidInterface() {
    public Void action(Void v) {
        //do something
        return v;
    }
}

and either lack of return statement or argument will give you a compiler error.

Therefore, if you declare a function which takes an argument and returns one, I think it is impossible to convert it to function which does neither of mentioned above.

I had a similar issue and ended up with this:

For me this has the advantage that data and annotation are not overlapping.

from matplotlib import pyplot as plt
import numpy as np

fig = plt.figure()
ax = fig.add_subplot(111)

A = -0.75, -0.25, 0, 0.25, 0.5, 0.75, 1.0
B = 0.73, 0.97, 1.0, 0.97, 0.88, 0.73, 0.54

plt.plot(A,B)

# annotations at the side (ordered by B values)
x0,x1=ax.get_xlim()
y0,y1=ax.get_ylim()
for ii, ind in enumerate(np.argsort(B)):
    x = A[ind]
    y = B[ind]
    xPos = x1 + .02 * (x1 - x0)
    yPos = y0 + ii * (y1 - y0)/(len(B) - 1)
    ax.annotate('',#label,
          xy=(x, y), xycoords='data',
          xytext=(xPos, yPos), textcoords='data',
          arrowprops=dict(
                          connectionstyle="arc3,rad=0.",
                          shrinkA=0, shrinkB=10,
                          arrowstyle= '-|>', ls= '-', linewidth=2
                          ),
          va='bottom', ha='left', zorder=19
          )
    ax.text(xPos + .01 * (x1 - x0), yPos,
            '({:.2f}, {:.2f})'.format(x,y),
            transform=ax.transData, va='center')

plt.grid()
plt.show()

Using the text argument in .annotate ended up with unfavorable text positions. Drawing lines between a legend and the data points is a mess, as the location of the legend is hard to address.

The exponential function is e^x where e is a mathematical constant called Euler's number, approximately 2.718281. This value has a close mathematical relationship with pi and the slope of the curve e^x is equal to its value at every point. np.exp() calculates e^x for each value of x in your input array.

I think you are trying to do as done in this DEMO

As above the question was originally about MySQL

Use REGEXP, not LIKE:

SELECT * FROM `table` WHERE ([url] NOT REGEXP '^[-A-Za-z0-9/.]+$')

If column A contains the amounts to be reimbursed, and column B contains the "yes/no" indicating whether the reimbursement has been made, then either of the following will work, though the first option is recommended:

=SUMIF(B:B,"No",A:A)

or

=SUMIFS(A:A,B:B,"No")

Here is an example that will display the amounts paid and outstanding for a small set of sample data.

 A         B            C                   D
 Amount    Reimbursed?  Total Paid:         =SUMIF(B:B,"Yes",A:A)
 $100      Yes          Total Outstanding:  =SUMIF(B:B,"No",A:A)
 $200      No           
 $300      No
 $400      Yes
 $500      No

[self dismissModalViewControllerAnimated:NO]; has been deprecated.

Use [self dismissViewControllerAnimated:NO completion:nil]; instead.

For example, you can invoke a private constructor inside a friend class or a friend function.

Singleton pattern usually uses it to make sure that nobody creates more instances of the intended type.

You can use:

f.Controls[name];

Where f is your form variable. That gives you the control with name name.

<script type="text/javascript">
$('a').click(function(){
   return false;
});
<script>

make a SELECT of it,

like if you got

UPDATE users SET id=0 WHERE name='jan'

convert it to

SELECT * FROM users WHERE name='jan'

You can use the $$ variable.

What's in my .vimrc?

ngn@macavity:~$ cat .vimrc
" This file intentionally left blank

The real config files lie under ~/.vim/ :)

And most of the stuff there is parasiting on other people's efforts, blatantly adapted from vim.org to my editing advantage.

Here's a modern solution that doesn't have the pitfalls of Object.assign() (does not copy by reference):

const cloneObj = (obj) => {
    return Object.keys(obj).reduce((dolly, key) => {
        dolly[key] = (obj[key].constructor === Object) ?
            cloneObj(obj[key]) :
            obj[key];
        return dolly;
    }, {});
};

It allows servlets to have multiple servlet mappings:

<servlet>
    <servlet-name>Servlet1</servlet-name>
    <servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/bill</url-pattern>
</servlet-mapping>

It allows filters to be mapped on the particular servlet:

<filter-mapping>
    <filter-name>Filter1</filter-name>
    <servlet-name>Servlet1</servlet-name>
</filter-mapping>

Your proposal would support neither of them. Note that the web.xml is read and parsed only once during application's startup, not on every HTTP request as you seem to think.

Since Servlet 3.0, there's the @WebServlet annotation which minimizes this boilerplate:

@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {

See also:

• How do servlets work? Instantiation, sessions, shared variables and multithreading

another solution is to override the join operator of the str class.

Let us define a new class my_string as follows

class my_string(str):
    def join(self, l):
        l_tmp = [str(x) for x in l]
        return super(my_string, self).join(l_tmp)

Then you can do

class Obj:
    def __str__(self):
        return 'name'

list = [Obj(), Obj(), Obj()]
comma = my_string(',')

print comma.join(list)

and you get

name,name,name

BTW, by using list as variable name you are redefining the list class (keyword) ! Preferably use another identifier name.

Hope you'll find my answer useful.

A thorough explanation of the Singleton macro code is on the blog Cocoa With Love

For all who came here from google and are using an anchor element for firing the event, please make sure to void the click likewise:

<a

onclick='javascript:whatever causing the page to scroll to the top'  
></a>

In a new upcoming php7 among many other features, they added a support for strings bigger than 2^31 bytes:

Support for strings with length >= 2^31 bytes in 64 bit builds.

Sadly they did not specify how much bigger can it be.

This did it for me:

USE [master];
GO
ALTER DATABASE [OldDataBaseName] SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
GO
EXEC sp_renamedb N'OldDataBaseName', N'NewDataBaseName';


-- Add users again
ALTER DATABASE [NewDataBaseName] SET MULTI_USER
GO

You could use the old ways. And use a table. In the table you define 3 columns. You set the width of your whole table and define the width of every colum. that way you can horizantaly space 2 objects. You put object one inside cell1 (colum1, row1) and object2 in cell3 (colum 3, row 1) and you leave cell 2 empty. Given it has a width, you will see empty spaces. example

<table width="500">
    <tr>
        <td width="40%">
            Object 1
        </td>
        <td width="20%">

        </td>
        <td width="40%">
            Object 2
        </td>
    </tr>
</table>

Or you could go the better way with div's. Just put your objects inside divs. Add a middle div and put these 3 divs inside another div. At the css style to the upper div: overflow: auto and define a width. Add css style to the 3 divs to define their width and add float: left example

<div style="overflow: auto;width: 100%;">
    <div style="width:200px;float: left;">
        Object  1
    </div>
    <div style="width:200px;float: left;">

    </div>
    <div style="width:200px;float: left;">
        Object  2
    </div>
</div>

Which version of Firefox on which platform is your client using?

The are people having the same problem as documented here in the Support Forum for Firefox. I hope you can find a solution there. Good luck!

Update:

Let your client check the settings in Firefox: On "Advanced" - "Encryption" there is a button "View Certificates". Look for "Comodo CA Limited" in the list. I saw that Comodo is the issuer of the certificate of that domain name/server. On two of my machines (FF 3.0.3 on Vista and Mac) the entry is in the list (by default/Mozilla).

Some others from:

http://www.ruby-lang.org/en/documentation/ruby-from-other-languages/to-ruby-from-python/

(If I have misintrepreted anything or any of these have changed on the Ruby side since that page was updated, someone feel free to edit...)

Strings are mutable in Ruby, not in Python (where new strings are created by "changes").

Ruby has some enforced case conventions, Python does not.

Python has both lists and tuples (immutable lists). Ruby has arrays corresponding to Python lists, but no immutable variant of them.

In Python, you can directly access object attributes. In Ruby, it's always via methods.

In Ruby, parentheses for method calls are usually optional, but not in Python.

Ruby has public, private, and protected to enforce access, instead of Python’s convention of using underscores and name mangling.

Python has multiple inheritance. Ruby has "mixins."

And another very relevant link:

http://c2.com/cgi/wiki?PythonVsRuby

Which, in particular, links to another good one by Alex Martelli, who's been also posting a lot of great stuff here on SO:

http://groups.google.com/group/comp.lang.python/msg/028422d707512283

You could also use the store library which performs it for you with crossbrowser ability.

example :

// Store current user
store.set('user', { name:'Marcus' })

// Get current user
store.get('user')

// Remove current user
store.remove('user')

// Clear all keys
store.clearAll()

// Loop over all stored values
store.each(function(value, key) {
    console.log(key, '==', value)
})

You can actually disable all database constraints in a single SQL command and the re-enable them calling another single command. See:

• Can foreign key constraints be temporarily disabled using TSQL?

I am currently working with SQL Server 2005 but I am almost sure that this approach worked with SQL 2000 as well

Use Calendar.add(int field,int amount) method.

}]


checkCurrentLession(current){

 this.classes.forEach((obj)=>{
    if(obj.currentLession == current){
      return true;
    }

  });
  return false;
}

             [disabled]="checkCurrentLession(1)" class="primair">
               Start lesson</button>
        </li>
        <li>
          <p>Lesson 2</p>
          <button [routerLink]="['/lesson2']" 
             [disabled]="!checkCurrentLession(2)" class="primair">
               Start lesson</button>
        </li>
     </ul>

Some syntax sugar

1 in [1,2,3]

just

$(window).resize();

is what I use... unless I misunderstand what you're asking for.

I ran into this having 2 Doctrine DBAL connections, one of those as non-transactional (for important logs), they are intended to run parallel not depending on each other.

CodeExecution(
    TransactionConnectionQuery()
    TransactionlessConnectionQuery()
)

My integration tests were wrapped into transactions for data rollback after very test.

beginTransaction()
CodeExecution(
    TransactionConnectionQuery()
    TransactionlessConnectionQuery() // CONFLICT
)
rollBack()

My solution was to disable the wrapping transaction in those tests and reset the db data in another way.

You can also use this syntax: (in column D to concatenate A, B, and C)

=A2 & " """ & B2 & """ " & C2

I'm not sure if you want to find duplicate files or just compare two single files. If the latter, the above approach (filecmp) is better, if the former, the following approach is better.

There are lots of duplicate files detection questions here. Assuming they are not very small and that performance is important, you can

• Compare file sizes first, discarding all which doesn't match
• If file sizes match, compare using the biggest hash you can handle, hashing chunks of files to avoid reading the whole big file

Here's is an answer with Python implementations (I prefer the one by nosklo, BTW)

I recently worked on a project to read the RFID tags. The project used the Devices from manufacturers like Zebra (we were using RFD8500 ) & TSL.

More devices are from Motorola & other vendors as well!

We have to use the native SDK api's provided by the manufacturer, how it works is by pairing the device by the Bluetooth of the phones and so the data transfer between both devices take place! The programming is based on subscribe pattern where the scan should be read by the device trigger(hardware trigger) or soft trigger (from the application).

The Tag read gives us the tagId & the RSSI which is the distance factor from the RFID tags!

This is the sample app:

We get all the device paired to our Android/iOS phones :

Update 2019 - Bootstrap 4.3.1

There's no need for extra CSS. What's already included in Bootstrap will work. Make sure the container(s) of the form are full height. Bootstrap 4 now has a h-100 class for 100% height...

Vertical center:

<div class="container h-100">
  <div class="row h-100 justify-content-center align-items-center">
    <form class="col-12">
      <div class="form-group">
        <label for="formGroupExampleInput">Example label</label>
        <input type="text" class="form-control" id="formGroupExampleInput" placeholder="Example input">
      </div>
      <div class="form-group">
        <label for="formGroupExampleInput2">Another label</label>
        <input type="text" class="form-control" id="formGroupExampleInput2" placeholder="Another input">
      </div>
    </form>   
  </div>
</div>

https://codeply.com/go/raCutAGHre

the height of the container with the item(s) to center should be 100% (or whatever the desired height is relative to the centered item)

Note: When using height:100% (percentage height) on any element, the element takes in the height of it's container. In modern browsers vh units height:100vh; can be used instead of % to get the desired height.

Therefore, you can set html, body {height: 100%}, or use the new min-vh-100 class on container instead of h-100.

Horizontal center:

• text-center to center display:inline elements & column content
• mx-auto for centering inside flex elements
• offset-* or mx-auto can be used to center columns (.col-)
• justify-content-center to center columns (col-*) inside row

Vertical Align Center in Bootstrap 4
Bootstrap 4 full-screen centered form
Bootstrap 4 center input group
Bootstrap 4 horizontal + vertical center full screen

data$anim <- sapply(0, paste0,data$anim)

You absolutely need to know where the files to be read can be located. However, this information can be relative of course so it may be well adapted to other systems.

So it could relate to the current directory (get it from Directory.GetCurrentDirectory()) or to the application executable path (eg. Application.ExecutablePath comes to mind if using Windows Forms or via Assembly.GetEntryAssembly().Location) or to some special Windows directory like "Documents and Settings" (you should use Environment.GetFolderPath() with one element of the Environment.SpecialFolder enumeration).

Note that the "current directory" and the path of the executable are not necessarily identical. You need to know where to look!

In either case, if you need to manipulate a path use the Path class to split or combine parts of the path.

for a series: used describe functions

suppose you have df with following columns sales and id. you want to calculate percentiles for sales then it works like this,

df['sales'].describe(percentiles = [0.0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1])

0.0: .0: minimum
1: maximum 
0.1 : 10th percentile and so on

I believe you're looking for the @filename syntax, e.g.:

strip new lines

curl --data "@/path/to/filename" http://...

keep new lines

curl --data-binary "@/path/to/filename" http://...

curl will strip all newlines from the file. If you want to send the file with newlines intact, use --data-binary in place of --data

var form = $("<form/>", 
                 { action:'/myaction' }
            );
form.append( 
    $("<input>", 
         { type:'text', 
           placeholder:'Keywords', 
           name:'keyword', 
           style:'width:65%' }
     )
);

form.append( 
     $("<input>", 
          { type:'submit', 
            value:'Search', 
            style:'width:30%' }
       )
);

$("#someDivId").append(form);

If you are using MySql Wamp. This code work.

string con="SERVER=localhost; user id=root; password=; database=dbname";
public void delete()
{
try
{
MySqlConnection connect = new MySqlConnection(con);
MySqlDataAdapter da = new MySqlDataAdapter();
connect.Open();
da.DeleteCommand = new MySqlCommand("DELETE FROM table WHERE ID='" + ID.Text + "'", connect);
da.DeleteCommand.ExecuteNonQuery();

MessageBox.Show("Successfully Deleted");
}
catch(Exception e)
{
MessageBox.Show(e.Message);
}
}

First of all you missed ScriptService attribute to add in webservice.

[ScriptService]

After then try following method to call webservice via JSON.

        var webAddr = "http://Domain/VBRService.asmx/callJson";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        httpWebRequest.ContentType = "application/json; charset=utf-8";
        httpWebRequest.Method = "POST";            

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = "{\"x\":\"true\"}";

            streamWriter.Write(json);
            streamWriter.Flush();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            return result;
        }

You should use Node.contains, since it's now standard and available in all browsers.

One more solution, version for the 'years' difference:

SELECT count(*) - 1 FROM (SELECT distinct(date_trunc('year', generate_series('2010-04-01'::timestamp, '2012-03-05', '1 week')))) x

    2

(1 row)

And the same trick for the months:

SELECT count(*) - 1 FROM (SELECT distinct(date_trunc('month', generate_series('2010-04-01'::timestamp, '2012-03-05', '1 week')))) x

   23

(1 row)

In real life query there can be some timestamp sequences grouped by hour/day/week/etc instead of generate_series.

This 'count(distinct(date_trunc('month', ts)))' can be used right in the 'left' side of the select:

SELECT sum(a - b)/count(distinct(date_trunc('month', c))) FROM d

I used generate_series() here just for the brevity.

i've mandained some similar page (classic asp...)

my approach was to use Q promise directly on the popup.

For example my problem was that the popup i wanted to print close itself too fast ... and the print previw was empty, i solved this way :

Caller :

var popup = window.open("index.asp","popupwindow","width=800,height=500,left=200,top=5,scrollbars,toolbar=0,resizable");

Popup (at the end of the page):

<script src="/Scripts/jquery-1.9.1.min.js"></script>
<script src="/Scripts/q.min.js"></script>
<script type="text/javascript">
    Q(window.print()).then(function () {window.close();});
</script>

I think that your "parent lock" could be solved in a similar way

i would try :

var w = whatever;
Q(
  // fill your popup
).then(function () {
 w.print();
}).then(function () {
 w.close();
}); 

that makes "the print" and "the close" async... so the parent will be immediately "unlocked"

Just as a tidbit:

Even (((A)null)instanceof A) will return false.

(If typecasting null seems surprising, sometimes you have to do it, for example in situations like this:

public class Test
{
  public static void test(A a)
  {
    System.out.println("a instanceof A: " + (a instanceof A));
  }

  public static void test(B b) {
    // Overloaded version. Would cause reference ambiguity (compile error)
    // if Test.test(null) was called without casting.
    // So you need to call Test.test((A)null) or Test.test((B)null).
  }
}

So Test.test((A)null) will print a instanceof A: false.)

P.S.: If you are hiring, please don't use this as a job interview question. :D

Dynamic PDF Viewer from ceTe software might do what you're looking for. I've used their generator software and was pretty happy with it.

http://www.dynamicpdf.com/

You do not need to select the columns separately in order to use them in your CONCAT. Simply remove them, and your query will become:

SELECT FirstName AS First_Name
     , LastName AS Last_Name
     , CONCAT(ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
  FROM TABLE1

New Date(number) returns a date that's number milliseconds after 1 Jan 1970. Odds are you date format isn't showing hours, minutes, and seconds for you to see that it's just a little bit after 1 Jan 1970.

You need to parse the date according to the correct parsing routing. I don't know what a 1220227200 is, but if it's seconds after 1 JAN 1970, then multiply it to yield milliseconds. If it is not, then convert it in some manner to milliseconds after 1970 (if you want to continue to use java.util.Date).

Change the order you're including your scripts (jQuery first):

<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript" src="./javascript.js"></script>
<script
    src="http://maps.googleapis.com/maps/api/js?key=YOUR_APIKEY&sensor=false">
</script>

If you're like me and tried a few of these methods and are stuck at the point that you have the control in the toolbox and can draw it on the form but it disappears from the form and puts it down in the components, then simply edit the designer and add the following in the appropriate area of InitializeComponent() to make it visible:

this.Controls.Add(this.reportViewer1);

or

[ContainerControl].Controls.Add(this.reportViewer1);

You'll also need to make adjustments to the location and size manually after you've added the control.

Not a great answer for sure, but if you're stuck and just need to get work done for now until you have more time to figure it out, it should help.

Lots of answers above! here is my take:

Sub kl()

    Dim wb As Workbook
    Dim ws As Worksheet

    Set ws = Sheets("name")
    Set wb = ThisWorkbook

With ws
    .Select
End With

End Sub

your first (perhaps accidental) mistake as we have all mentioned is "Sheet"... should be "Sheets"

The with block is useful because if you set wb to anything other than the current workbook, it will ececute properly

Aergistal's answer works, but I found that converting to mp4 can make some m3u8 videos broken. If you are stuck with this problem, try to convert them to mkv, and convert them to mp4 later.

Yet another option is to cast the XML as nvarchar, and then search for the given string as if the XML vas a nvarchar field.

SELECT * 
FROM Table
WHERE CAST(Column as nvarchar(max)) LIKE '%TEST%'

I love this solution as it is clean, easy to remember, hard to mess up, and can be used as a part of a where clause.

EDIT: As Cliff mentions it, you could use:

...nvarchar if there's characters that don't convert to varchar

Because the bootstrap-select is a bootstrap component and therefore you need to include it in your code as you did for your V3

NOTE: this component only works in boostrap-4 since version 1.13.0

$('select').selectpicker();

The following debug_msg procedure can be called to simply output a debug message to the console:

DELIMITER $$

DROP PROCEDURE IF EXISTS `debug_msg`$$
DROP PROCEDURE IF EXISTS `test_procedure`$$

CREATE PROCEDURE debug_msg(enabled INTEGER, msg VARCHAR(255))
BEGIN
  IF enabled THEN
    select concat('** ', msg) AS '** DEBUG:';
  END IF;
END $$

CREATE PROCEDURE test_procedure(arg1 INTEGER, arg2 INTEGER)
BEGIN
  SET @enabled = TRUE;

  call debug_msg(@enabled, 'my first debug message');
  call debug_msg(@enabled, (select concat_ws('','arg1:', arg1)));
  call debug_msg(TRUE, 'This message always shows up');
  call debug_msg(FALSE, 'This message will never show up');
END $$

DELIMITER ;

Then run the test like this:

CALL test_procedure(1,2)

It will result in the following output:

** DEBUG:
** my first debug message
** DEBUG:
** arg1:1
** DEBUG:
** This message always shows up

You can also try:

create table new_table as
select * from table1
union
select * from table2

There are several snippets here. However, this one is compact, efficient, and C++11 friendly:

static std::string base64_encode(const std::string &in) {

    std::string out;

    int val = 0, valb = -6;
    for (uchar c : in) {
        val = (val << 8) + c;
        valb += 8;
        while (valb >= 0) {
            out.push_back("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"[(val>>valb)&0x3F]);
            valb -= 6;
        }
    }
    if (valb>-6) out.push_back("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"[((val<<8)>>(valb+8))&0x3F]);
    while (out.size()%4) out.push_back('=');
    return out;
}

static std::string base64_decode(const std::string &in) {

    std::string out;

    std::vector<int> T(256,-1);
    for (int i=0; i<64; i++) T["ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"[i]] = i;

    int val=0, valb=-8;
    for (uchar c : in) {
        if (T[c] == -1) break;
        val = (val << 6) + T[c];
        valb += 6;
        if (valb >= 0) {
            out.push_back(char((val>>valb)&0xFF));
            valb -= 8;
        }
    }
    return out;
}

This is also useful if you only want to temporarily suppress the warning:

import matplotlib.pyplot as plt
       
with plt.rc_context(rc={'figure.max_open_warning': 0}):
    lots_of_plots()

I found the problem that was causing the HTTP error.

In the setFalse() function that is triggered by the Save button my code was trying to submit the form that contained the button.

        function setFalse(){
            document.getElementById("hasId").value ="false";
            document.deliveryForm.submit();
            document.submitForm.submit();

when I remove the document.submitForm.submit(); it works:

        function setFalse(){
            document.getElementById("hasId").value ="false";
            document.deliveryForm.submit()

@Roger Lindsjö Thank you for spotting my error where I wasn't passing on the right parameter!

Please add this option:

//Boolean - Whether the scale should start at zero, or an order of magnitude down from the lowest value
scaleBeginAtZero : true,

You should be able to install m2e (maven project for eclipse) using the Help -> Install New Software dialog. On that dialog open the Juno site (http://download.eclipse.org/releases/juno) and expand the Collaboration group (or type m2e into the filter). Select the two m2e options and follow the installation dialog

Try this

<xs:element name="description" type="xs:string" minOccurs="0" maxOccurs="1" />

if you want 0 or 1 "description" elements, Or

<xs:element name="description" type="xs:string" minOccurs="0" maxOccurs="unbounded" />

if you want 0 to infinity number of "description" elements.

From my knowledge, this is not possible.

Your browser has to have access to JS files to be able to execute them. If the browser has access, then browser's user also has access.

If you password protect your JS files, then the browser won't be able to access them, defeating the purpose of having JS in the first place.

The static keyword, when applied to a class, tells the compiler to create a single instance of that class. It is not then possible to 'new' one or more instance of the class. All methods in a static class must themselves be declared static.

It is possible, And often desirable, to have static methods of a non-static class. For example a factory method when creates an instance of another class is often declared static as this means that a particular instance of the class containing the factor method is not required.

For a good explanation of how, when and where see MSDN

I came to this situation when I installed node js from the latest stable release.

curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -

It seems this version already comes with a prepackaged NPM. So when I tried to install NPM again, I got this error. If anyone is installing Nodejs in this manner then, it's not needed to install NPM separately.

Lots of options here, but one of the easiest to follow is subset. Consider:

> set.seed(43)
> df <- data.frame(name = sample(letters, 100, TRUE), date = sample(1:500, 100, TRUE))
> 
> subset(df, date > 5 & date < 15)
   name date
11    k   10
67    y   12
86    e    8

You can also insert logic directly into the index for your data.frame. The comma separates the rows from columns. We just have to remember that R indexes rows first, then columns. So here we are saying rows with date > 5 & < 15 and then all columns:

df[df$date > 5 & df$date < 15 ,]

I'd also recommend checking out the help pages for subset, ?subset and the logical operators ?"&"

To add button you may use either jQuery libraries or simple Javascript script as shown below:

HTML link or button:

<a href="#" onClick="goclear()" id="button">click event</a>

Javascript:

<script type="text/javascript">
var btn = document.getElementById('button');
function goclear() { 
alert("Handler called. Page will redirect to clear.php");
document.location.href = "clear.php";
};
</script>

Use PHP to clear a file content. For instance you can use the fseek($fp, 0); or ftruncate ( resource $file , int $size ) as below:

<?php
//open file to write
$fp = fopen("/tmp/file.txt", "r+");
// clear content to 0 bits
ftruncate($fp, 0);
//close file
fclose($fp);
?>

Redirect PHP - you can use header ( string $string [, bool $replace = true [, int $http_response_code ]] )

<?php
header('Location: getbacktoindex.html');
?>

I hope it's help.

Using find / replace, try pasting a selection starting at the end of the line above the blank line and ends at the beginning of the line after the blank. This works for a single blank line. You can repeat the process for multiple blank lines as well. CTRL-H, put your selection in the find box and put a single newline in the replace box via copy/paste or other method.

I'm doing something like the following code. It works for USB-devices and also the stupid serial8250-devuices that we all have 30 of - but only a couple of them realy works.

Basically I use concept from previous answers. First enumerate all tty-devices in /sys/class/tty/. Devices that does not contain a /device subdir is filtered away. /sys/class/tty/console is such a device. Then the devices actually containing a devices in then accepted as valid serial-port depending on the target of the driver-symlink fx.

$ ls -al /sys/class/tty/ttyUSB0//device/driver
lrwxrwxrwx 1 root root 0 sep  6 21:28 /sys/class/tty/ttyUSB0//device/driver -> ../../../bus/platform/drivers/usbserial

and for ttyS0

$ ls -al /sys/class/tty/ttyS0//device/driver
lrwxrwxrwx 1 root root 0 sep  6 21:28 /sys/class/tty/ttyS0//device/driver -> ../../../bus/platform/drivers/serial8250

All drivers driven by serial8250 must be probes using the previously mentioned ioctl.

        if (ioctl(fd, TIOCGSERIAL, &serinfo)==0) {
            // If device type is no PORT_UNKNOWN we accept the port
            if (serinfo.type != PORT_UNKNOWN)
                the_port_is_valid

Only port reporting a valid device-type is valid.

I could not compile QT5 with any of the (fairly outdated) toolchains from git://github.com/raspberrypi/tools.git. The configure script kept failing with an "could not determine architecture" error and with massive path problems for include directories. What worked for me was using the Linaro toolchain

http://releases.linaro.org/components/toolchain/binaries/4.9-2016.02/arm-linux-gnueabihf/runtime-linaro-gcc4.9-2016.02-arm-linux-gnueabihf.tar.xz

in combination with

https://raw.githubusercontent.com/riscv/riscv-poky/master/scripts/sysroot-relativelinks.py

Failing to fix the symlinks of the sysroot leads to undefined symbol errors as described here: An error building Qt libraries for the raspberry pi This happened to me when I tried the fixQualifiedLibraryPaths script from tools.git. Everthing else is described in detail in http://wiki.qt.io/RaspberryPi2EGLFS . My configure settings were:

./configure -opengl es2 -device linux-rpi3-g++ -device-option CROSS_COMPILE=/usr/local/rasp/gcc-linaro-4.9-2016.02-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /usr/local/rasp/sysroot -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi

with /usr/local/rasp/sysroot being the path of my local Raspberry Pi 3 Raspbian (Jessie) system copy and /usr/local/qt5pi being the path of the cross compiled QT that also has to be copied to the device. Be aware that Jessie comes with GCC 4.9.2 when you choose your toolchain.

do it simply

public class Test{
    public Test(){
        design();
    }//end Test()

public void design(){
    JFame f = new JFrame();
    f.setSize(int w, int h);
    f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
    f.setVisible(true);
    JPanel p = new JPanel(); 
    f.getContentPane().add(p);
}

public static void main(String[] args){
     EventQueue.invokeLater(new Runnable(){
     public void run(){
         try{
             new Test();
         }catch(Exception e){
             e.printStackTrace();
         }

 }
         );
}

}

I feel like there should be a no javascript solution, but how is this?

http://jsfiddle.net/NfmX3/2/

$(window).resize(function() {
    $('#content').height($(window).height() - 46);
});

$(window).trigger('resize');

First, use Array.from to convert the HTMLCollection object to an array.

let selectElement = document.getElementById('categorySelect')
let selectedValues = Array.from(selectElement.selectedOptions)
        .map(option => option.value) // make sure you know what '.map' does

// you could also do: selectElement.options

I think you could use the following HTML and CSS combo instead:

<li>
  <a href="#">Backback</a>
</li>

Then use CSS background for the basket visibility on hover:

.listblock ul li a {
    padding: 5px 30px 5px 10px;
    display: block;
}

.listblock ul li a:hover {
    background: transparent url('../img/basket.png') no-repeat 3px 170px;
}

Simples!

According to this code golfing solution by Gaffi, the following works:

a = Split(StrConv(s, 64), Chr(0))

I use a slightly more concise version:

expect(() => {
  // Code block that should throw error
}).toThrow(TypeError) // Or .toThrow('expectedErrorMessage')

Difference b/w scp and rsync on different parameter

1. Performance over latency

• scp : scp is relatively less optimise and speed

• rsync : rsync is comparatively more optimise and speed

https://www.disk91.com/2014/technology/networks/compare-performance-of-different-file-transfer-protocol-over-latency/

2. Interruption handling

• scp : scp command line tool cannot resume aborted downloads from lost network connections

• rsync : If the above rsync session itself gets interrupted, you can resume it as many time as you want by typing the same command. rsync will automatically restart the transfer where it left off.

http://ask.xmodulo.com/resume-large-scp-file-transfer-linux.html

3. Command Example

scp

$ scp source_file_path destination_file_path

rsync

$ cd /path/to/directory/of/partially_downloaded_file
$ rsync -P --rsh=ssh [email protected]:bigdata.tgz ./bigdata.tgz 

The -P option is the same as --partial --progress, allowing rsync to work with partially downloaded files. The --rsh=ssh option tells rsync to use ssh as a remote shell.

4. Security :

scp is more secure. You have to use rsync --rsh=ssh to make it as secure as scp.

• scp : http://www.manpagez.com/man/1/scp/
• rsync : http://www.manpagez.com/man/1/rsync/

VSCode comes with in-built color themes which can be used to change the colors of the editor and the terminal.

• For changing the color theme press ctrl+k+t in windows/ubuntu or cmd+k+t on mac.
• Alternatively you can open command palette by pressing ctrl+shift+p in windows/ubuntu or cmd+shift+p on mac and type color. Select preferences: color theme from the options, to select your favourite color.
• You can also install more themes from the extensions menu on the left bar. just search category:themes to install your favourite themes. (If you need to sort the themes by installs search category:themes @sort:installs)

Edit - for manually editing colors in terminal

VSCode team have removed customizing colors from user settings page. Currently using the themes is the only way to customize terminal colors in VSCode. For more information check out issue #6766

One way to handle this is to create a new BufferedImage, and tell it's graphics object to draw your scaled image into the new BufferedImage:

final float FACTOR  = 4f;
BufferedImage img = ImageIO.read(new File("graphic.png"));
int scaleX = (int) (img.getWidth() * FACTOR);
int scaleY = (int) (img.getHeight() * FACTOR);
Image image = img.getScaledInstance(scaleX, scaleY, Image.SCALE_SMOOTH);
BufferedImage buffered = new BufferedImage(scaleX, scaleY, TYPE);
buffered.getGraphics().drawImage(image, 0, 0 , null);

That should do the trick without casting.

For Oracle, John's solution using instr() function works. Here's slightly different solution that worked - SELECT id FROM table1 WHERE id IN (1, 20, 45, 60) ORDER BY instr('1, 20, 45, 60', id)

TL;DR: git branch --set-upstream-to origin/solaris

The answer to the question you asked—which I'll rephrase a bit as "do I have to set an upstream"—is: no, you don't have to set an upstream at all.

If you do not have upstream for the current branch, however, Git changes its behavior on git push, and on other commands as well.

The complete push story here is long and boring and goes back in history to before Git version 1.5. To shorten it a whole lot, git push was implemented poorly.¹ As of Git version 2.0, Git now has a configuration knob spelled push.default which now defaults to simple. For several versions of Git before and after 2.0, every time you ran git push, Git would spew lots of noise trying to convince you to set push.default just to get git push to shut up.

You do not mention which version of Git you are running, nor whether you have configured push.default, so we must guess. My guess is that you are using Git version 2-point-something, and that you have set push.default to simple to get it to shut up. Precisely which version of Git you have, and what if anything you have push.default set to, does matter, due to that long and boring history, but in the end, the fact that you're getting yet another complaint from Git indicates that your Git is configured to avoid one of the mistakes from the past.

What is an upstream?

An upstream is simply another branch name, usually a remote-tracking branch, associated with a (regular, local) branch.

Every branch has the option of having one (1) upstream set. That is, every branch either has an upstream, or does not have an upstream. No branch can have more than one upstream.

The upstream should, but does not have to be, a valid branch (whether remote-tracking like origin/B or local like master). That is, if the current branch B has upstream U, git rev-parse U should work. If it does not work—if it complains that U does not exist—then most of Git acts as though the upstream is not set at all. A few commands, like git branch -vv, will show the upstream setting but mark it as "gone".

What good is an upstream?

If your push.default is set to simple or upstream, the upstream setting will make git push, used with no additional arguments, just work.

That's it—that's all it does for git push. But that's fairly significant, since git push is one of the places where a simple typo causes major headaches.

If your push.default is set to nothing, matching, or current, setting an upstream does nothing at all for git push.

(All of this assumes your Git version is at least 2.0.)

The upstream affects git fetch

If you run git fetch with no additional arguments, Git figures out which remote to fetch from by consulting the current branch's upstream. If the upstream is a remote-tracking branch, Git fetches from that remote. (If the upstream is not set or is a local branch, Git tries fetching origin.)

The upstream affects git merge and git rebase too

If you run git merge or git rebase with no additional arguments, Git uses the current branch's upstream. So it shortens the use of these two commands.

The upstream affects git pull

You should never² use git pull anyway, but if you do, git pull uses the upstream setting to figure out which remote to fetch from, and then which branch to merge or rebase with. That is, git pull does the same thing as git fetch—because it actually runs git fetch—and then does the same thing as git merge or git rebase, because it actually runs git merge or git rebase.

(You should usually just do these two steps manually, at least until you know Git well enough that when either step fails, which they will eventually, you recognize what went wrong and know what to do about it.)

The upstream affects git status

This may actually be the most important. Once you have an upstream set, git status can report the difference between your current branch and its upstream, in terms of commits.

If, as is the normal case, you are on branch B with its upstream set to origin/B, and you run git status, you will immediately see whether you have commits you can push, and/or commits you can merge or rebase onto.

This is because git status runs:

• git rev-list --count @{u}..HEAD: how many commits do you have on B that are not on origin/B?
• git rev-list --count HEAD..@{u}: how many commits do you have on origin/B that are not on B?

Setting an upstream gives you all of these things.

How come master already has an upstream set?

When you first clone from some remote, using:

$ git clone git://some.host/path/to/repo.git

or similar, the last step Git does is, essentially, git checkout master. This checks out your local branch master—only you don't have a local branch master.

On the other hand, you do have a remote-tracking branch named origin/master, because you just cloned it.

Git guesses that you must have meant: "make me a new local master that points to the same commit as remote-tracking origin/master, and, while you're at it, set the upstream for master to origin/master."

This happens for every branch you git checkout that you do not already have. Git creates the branch and makes it "track" (have as an upstream) the corresponding remote-tracking branch.

But this doesn't work for new branches, i.e., branches with no remote-tracking branch yet.

If you create a new branch:

$ git checkout -b solaris

there is, as yet, no origin/solaris. Your local solaris cannot track remote-tracking branch origin/solaris because it does not exist.

When you first push the new branch:

$ git push origin solaris

that creates solaris on origin, and hence also creates origin/solaris in your own Git repository. But it's too late: you already have a local solaris that has no upstream.³

Shouldn't Git just set that, now, as the upstream automatically?

Probably. See "implemented poorly" and footnote 1. It's hard to change now: There are millions⁴ of scripts that use Git and some may well depend on its current behavior. Changing the behavior requires a new major release, nag-ware to force you to set some configuration field, and so on. In short, Git is a victim of its own success: whatever mistakes it has in it, today, can only be fixed if the change is either mostly invisible, clearly-much-better, or done slowly over time.

The fact is, it doesn't today, unless you use --set-upstream or -u during the git push. That's what the message is telling you.

You don't have to do it like that. Well, as we noted above, you don't have to do it at all, but let's say you want an upstream. You have already created branch solaris on origin, through an earlier push, and as your git branch output shows, you already have origin/solaris in your local repository.

You just don't have it set as the upstream for solaris.

To set it now, rather than during the first push, use git branch --set-upstream-to. The --set-upstream-to sub-command takes the name of any existing branch, such as origin/solaris, and sets the current branch's upstream to that other branch.

That's it—that's all it does—but it has all those implications noted above. It means you can just run git fetch, then look around, then run git merge or git rebase as appropriate, then make new commits and run git push, without a bunch of additional fussing-around.

¹To be fair, it was not clear back then that the initial implementation was error-prone. That only became clear when every new user made the same mistakes every time. It's now "less poor", which is not to say "great".

²"Never" is a bit strong, but I find that Git newbies understand things a lot better when I separate out the steps, especially when I can show them what git fetch actually did, and they can then see what git merge or git rebase will do next.

³If you run your first git push as git push -u origin solaris—i.e., if you add the -u flag—Git will set origin/solaris as the upstream for your current branch if (and only if) the push succeeds. So you should supply -u on the first push. In fact, you can supply it on any later push, and it will set or change the upstream at that point. But I think git branch --set-upstream-to is easier, if you forgot.

javax.servlet is a package that's part of Java EE (Java Enterprise Edition). You've got the JDK for Java SE (Java Standard Edition).

You could use the Java EE SDK for example.

Alternatively simple servlet containers such as Apache Tomcat also come with this API (look for servlet-api.jar).

If you don't want to register a listener on every component,
you could add your own KeyEventDispatcher to the KeyboardFocusManager:

public class MyFrame extends JFrame {    
    private class MyDispatcher implements KeyEventDispatcher {
        @Override
        public boolean dispatchKeyEvent(KeyEvent e) {
            if (e.getID() == KeyEvent.KEY_PRESSED) {
                System.out.println("tester");
            } else if (e.getID() == KeyEvent.KEY_RELEASED) {
                System.out.println("2test2");
            } else if (e.getID() == KeyEvent.KEY_TYPED) {
                System.out.println("3test3");
            }
            return false;
        }
    }
    public MyFrame() {
        add(new JTextField());
        System.out.println("test");
        KeyboardFocusManager manager = KeyboardFocusManager.getCurrentKeyboardFocusManager();
        manager.addKeyEventDispatcher(new MyDispatcher());
    }

    public static void main(String[] args) {
        MyFrame f = new MyFrame();
        f.pack();
        f.setVisible(true);
    }
}

List_of_list =[([z for z in range(x-2,x+1) if z >= 0],y) for y in range(10) for x in range(10)]

This should do the trick. And the output is this:

[([0], 0), ([0, 1], 0), ([0, 1, 2], 0), ([1, 2, 3], 0), ([2, 3, 4], 0),  ([3, 4, 5], 0), ([4, 5, 6], 0), ([5, 6, 7], 0), ([6, 7, 8], 0), ([7, 8, 9], 0), ([0], 1), ([0, 1], 1), ([0, 1, 2], 1), ([1, 2, 3], 1), ([2, 3, 4], 1), ([3, 4, 5], 1), ([4, 5, 6], 1), ([5, 6, 7], 1), ([6, 7, 8], 1), ([7, 8, 9], 1), ([0], 2), ([0, 1], 2), ([0, 1, 2], 2), ([1, 2, 3], 2), ([2, 3, 4], 2), ([3, 4, 5], 2), ([4, 5, 6], 2), ([5, 6, 7], 2), ([6, 7, 8], 2), ([7, 8, 9], 2), ([0], 3), ([0, 1], 3), ([0, 1, 2], 3), ([1, 2, 3], 3), ([2, 3, 4], 3), ([3, 4, 5], 3), ([4, 5, 6], 3), ([5, 6, 7], 3), ([6, 7, 8], 3), ([7, 8, 9], 3), ([0], 4), ([0, 1], 4), ([0, 1, 2], 4), ([1, 2, 3], 4), ([2, 3, 4], 4), ([3, 4, 5], 4), ([4, 5, 6], 4), ([5, 6, 7], 4), ([6, 7, 8], 4), ([7, 8, 9], 4), ([0], 5), ([0, 1], 5), ([0, 1, 2], 5), ([1, 2, 3], 5), ([2, 3, 4], 5), ([3, 4, 5], 5), ([4, 5, 6], 5), ([5, 6, 7], 5), ([6, 7, 8], 5), ([7, 8, 9], 5), ([0], 6), ([0, 1], 6), ([0, 1, 2], 6), ([1, 2, 3], 6), ([2, 3, 4], 6), ([3, 4, 5], 6), ([4, 5, 6], 6), ([5, 6, 7], 6), ([6, 7, 8], 6), ([7, 8, 9], 6), ([0], 7), ([0, 1], 7), ([0, 1, 2], 7), ([1, 2, 3], 7), ([2, 3, 4], 7), ([3, 4, 5], 7), ([4, 5, 6], 7), ([5, 6, 7], 7), ([6, 7, 8], 7), ([7, 8, 9], 7), ([0], 8), ([0, 1], 8), ([0, 1, 2], 8), ([1, 2, 3], 8), ([2, 3, 4], 8), ([3, 4, 5], 8), ([4, 5, 6], 8), ([5, 6, 7], 8), ([6, 7, 8], 8), ([7, 8, 9], 8), ([0], 9), ([0, 1], 9), ([0, 1, 2], 9), ([1, 2, 3], 9), ([2, 3, 4], 9), ([3, 4, 5], 9), ([4, 5, 6], 9), ([5, 6, 7], 9), ([6, 7, 8], 9), ([7, 8, 9], 9)]    

This is done by list comprehension(which makes looping elements in a list via one line code possible). The logic behind this one-line code is the following:

(1) for x in range(10) and for y in range(10) are employed for two independent loops inside a list

(2) (a list, y) is the general term of the loop, which is why it is placed before two for's in (1)

(3) the length of the list in (2) cannot exceed 3, and the list depends on x, so

[z for z in range(x-2,x+1)] 

is used

(4) because z starts from zero but range(x-2,x+1) starts from -2 which isn't what we want, so a conditional statement if z >= 0 is placed at the end of the list in (2)

[z for z in range(x-2,x+1) if z >= 0] 

I supose the "opposite" would be to simulate an event. You could use .createEvent()

Following Mozilla's example:

function simulateClick() {
  var evt = document.createEvent("MouseEvents");
  evt.initMouseEvent("click", true, true, window,
    0, 0, 0, 0, 0, false, false, false, false, 0, null);
  var cb = document.getElementById("checkbox"); 
  var cancelled = !cb.dispatchEvent(evt);
  if(cancelled) {
    // A handler called preventDefault
    alert("cancelled");
  } else {
    // None of the handlers called preventDefault
    alert("not cancelled");
  }
}

Ref: document.createEvent

jQuery has .trigger() so you can trigger events on elements -- sometimes useful.

$('#foo').bind('click', function() {
      alert($(this).text());
});

$('#foo').trigger('click');

Actually it might be too late for this answer but you can now do this:

class Box {
    public x: number;
    public y: number;
    public height: number;
    public width: number;

    constructor();
    constructor(obj: IBox);
    constructor(obj?: IBox) {    
        this.x = !obj ? 0 : obj.x;
        this.y = !obj ? 0 : obj.y;
        this.height = !obj ? 0 : obj.height;
        this.width = !obj ? 0 : obj.width;
    }
}

so instead of static methods you can do the above. I hope it will help you!!!

You can use the str.isspace() method.

A rect can't contain a text element. Instead transform a g element with the location of text and rectangle, then append both the rectangle and the text to it:

var bar = chart.selectAll("g")
    .data(data)
  .enter().append("g")
    .attr("transform", function(d, i) { return "translate(0," + i * barHeight + ")"; });

bar.append("rect")
    .attr("width", x)
    .attr("height", barHeight - 1);

bar.append("text")
    .attr("x", function(d) { return x(d) - 3; })
    .attr("y", barHeight / 2)
    .attr("dy", ".35em")
    .text(function(d) { return d; });

Showing gifs need two things

1- Use this syntax as in these examples

![Alt Text](https://media.giphy.com/media/vFKqnCdLPNOKc/giphy.gif)

Yields:

2- The image url must end with gif

3- For posterity: if the .gif link above ever goes bad, you will not see the image and instead see the alt-text and URL, like this:

4- for resizing the gif you can use this syntax as in this Github tutorial link

<img src="https://media.giphy.com/media/vFKqnCdLPNOKc/giphy.gif" width="40" height="40" />

Yields:

This is intended behavior.

When you make an HTTP request, the server normally returns code 200 OK. If you set If-Modified-Since, the server may return 304 Not modified (and the response will not have the content). This is supposed to be your cue that the page has not been modified.

The authors of the class have foolishly decided that 304 should be treated as an error and throw an exception. Now you have to clean up after them by catching the exception every time you try to use If-Modified-Since.

This is one of those things that can be difficult to search for if you don't already know where to look.

[ is actually a command, not part of the bash shell syntax as you might expect. It happens to be a Bash built-in command, so it's documented in the Bash manual.

There's also an external command that does the same thing; on many systems, it's provided by the GNU Coreutils package.

[ is equivalent to the test command, except that [ requires ] as its last argument, and test does not.

Assuming the bash documentation is installed on your system, if you type info bash and search for 'test' or '[' (the apostrophes are part of the search), you'll find the documentation for the [ command, also known as the test command. If you use man bash instead of info bash, search for ^ *test (the word test at the beginning of a line, following some number of spaces).

Following the reference to "Bash Conditional Expressions" will lead you to the description of -ne, which is the numeric inequality operator ("ne" stands for "not equal). By contrast, != is the string inequality operator.

You can also find bash documentation on the web.

• Bash reference
• Bourne shell builtins (including test and [)
• Bash Conditional Expressions -- (Scroll to the bottom; -ne is under "arg1 OP arg2")
• POSIX documentation for test

The official definition of the test command is the POSIX standard (to which the bash implementation should conform reasonably well, perhaps with some extensions).

        case "iPhone5,1", "iPhone5,2", "iPhone5,3", "iPhone5,4", "iPhone6,1", "iPhone6,2", "iPhone8,4":
            return "iPhone 5"

        case "iPhone7,2", "iPhone8,1", "iPhone9,1", "iPhone9,3", "iPhone10,1", "iPhone10,4":
            return "iPhone 6,7,8"

        case "iPhone7,1", "iPhone8,2", "iPhone9,2", "iPhone9,4", "iPhone10,2", "iPhone10,5":
            return "iPhone Plus"

        case "iPhone10,3", "iPhone10,6":
            return "iPhone X"

        case "i386", "x86_64":
            return "Simulator"
        default:
            return identifier
        }
    }
}

And use:

switch UIDevice.current.modelName {
  case "iPhone 4":
  case "iPhone 5":
  case "iPhone 6,7,8":
  case "iPhone Plus":
  case "iPhone X":
  case "Simulator":
  default:
}

This method worked in my case.

video=getElementsByTagName('video');
function removeControls(video){
  video.removeAttribute('controls');
}
window.onload=removeControls(video);

This is my version of check ping function. May be if well be usefull for someone:

def check_ping(host):
if platform.system().lower() == "windows":
response = os.system("ping -n 1 -w 500 " + host + " > nul")
if response == 0:
return "alive"
else:
return "not alive"
else:
response = os.system("ping -c 1 -W 0.5" + host + "> /dev/null")
if response == 1:
return "alive"
else:
return "not alive"

Just use the Class method using this foobar->foobarfunc();

by default, NHibernate uses first level caching which is Session Object based. but if you are running in a multi-server environment, then the first level cache may not very scalable along with some performance issues. it is happens because of the fact that it has to make very frequent trips to the database as the data is distributed over multiple servers. in other words NHibernate provides a basic, not-so-sophisticated in-process L1 cache out of box. However, it doesn’t provide features that a caching solution must have to have a notable impact on the application performance.

so the questions of all these problem is the use of a L2 cache which is associated with the session factory objects. it reduces the time consuming trips to the database so ultimately increases the app response time.

This will only give you marginal protection. If the attacker can run arbitrary code in your application they can get at the passwords in exactly the same way your application can. You could still get some protection from some SQL injection attacks and misplaced db backups if you store a secret key in a file and use that to encrypt on the way to the db and decrypt on the way out. But you should use bindparams to completely avoid the issue of SQL injection.

If decide to encrypt, you should use some high level crypto library for this, or you will get it wrong. You'll have to get the key-setup, message padding and integrity checks correct, or all your encryption effort is of little use. GPGME is a good choice for one example. Mcrypt is too low level and you will probably get it wrong.

I always make a call from the end of the JavaScript files for registering its loading and it used to work perfect for me for all the browsers.

Ex: I have an index.htm, Js1.js and Js2.js. I add the function IAmReady(Id) in index.htm header and call it with parameters 1 and 2 from the end of the files, Js1 and Js2 respectively. The IAmReady function will have a logic to run the boot code once it gets two calls (storing the the number of calls in a static/global variable) from the two js files.

I had the same problem with a custom signature permission on Android-21 and solved it by making sure I was doing a complete uninstall.

This is an edge case that occurs when:

1. An application defines a custom permission using signature level security
2. You attempt to update the installed app with a version signed with a different key
3. The test device is running Android 21 or newer with support for multiple users

Command line example

Here is a command-line transcript that demonstrates the issue and how to solve it. At this point a debug version is installed and I am trying to install a production version signed with the release key:

# This fails because the debug version defines the custom permission signed with a different key:

[root@localhost svn-android-apps]# . androidbuildscripts/my-adb-install Example release
920 KB/s (2211982 bytes in 2.347s)
        pkg: /data/local/tmp/Example-release.apk
Failure [INSTALL_FAILED_DUPLICATE_PERMISSION perm=com.example.android.example.PERMISSION_EXAMPLE_PLUGIN pkg=com.example.android.example]

# I use uninstall -k because apparently that is similar to uninstalling as a user
# by dragging the app out of the app tray:

[root@localhost svn-android-apps]# /android-sdk-linux/platform-tools/adb uninstall -k com.example.android.example
The -k option uninstalls the application while retaining the data/cache.
At the moment, there is no way to remove the remaining data.
You will have to reinstall the application with the same signature, and fully uninstall it.
If you truly wish to continue, execute 'adb shell pm uninstall -k com.example.android.example'

# Let's go ahead and do that:

[root@localhost svn-android-apps]# /android-sdk-linux/platform-tools/adb shell pm uninstall -k com.example.android.example
Success

# This fails again because the custom permission apparently is part of the data/cache
# that was not uninstalled:

[root@localhost svn-android-apps]# . androidbuildscripts/my-adb-install Example release
912 KB/s (2211982 bytes in 2.367s)
        pkg: /data/local/tmp/Example-release.apk
Failure [INSTALL_FAILED_DUPLICATE_PERMISSION perm=com.example.android.example.PERMISSION_EXAMPLE_PLUGIN pkg=com.example.android.example]

# In spite of the warning above, simply doing a full uninstall at this point turned out to 
# work (for me):

[root@localhost svn-android-apps]# /android-sdk-linux/platform-tools/adb uninstall com.example.android.example
Success

# Release version now successfully installs:

[root@localhost svn-android-apps]# . androidbuildscripts/my-adb-install Example release
898 KB/s (2211982 bytes in 2.405s)
        pkg: /data/local/tmp/Example-release.apk
Success

[root@localhost svn-android-apps]# 

Eclipse example

Going in the opposite direction (trying to install a debug build from Eclipse when a release build is already installed), I get the following dialog:

If you just answer yes at this point the install will succeed.

Device example

As pointed out in another answer, you can also go to an app info page in the device settings, click the overflow menu, and select "Uninstall for all users" to prevent this error.

Try this to check

$('#captureImage').attr("checked",true).checkboxradio("refresh");

and uncheck

$('#captureImage').attr("checked",false).checkboxradio("refresh");  

You said that versioning local.properties creates problems for you. I've hacked together a script which uses android command line tool to refresh the local.properties file across the machines that are involved in the production. The android update project command, besides the local.properties produces a lot of unwanted trash (at least for me) which is the reason for all those rm commands at the end of the script.

#!/bin/bash
scname="$0"
echo "${scname}: updating local properties..."
ln -fs src/main/AndroidManifest.xml
android update project -t 24 -p "$(pwd)"
echo "${scname}: ...done"
echo "${scname}: removing android update project junk ..."
rm -v project.properties
rm -v build.xml
rm -v proguard-project.txt
rm -v AndroidManifest.xml
echo "${scname}: ...done"

This script is the first thing we run on any new machine where we code. It has to be run in the root project directory. Of course, android studio may have a GUI way of dealing with this, but I wouldn't know as I use a different editor. I also can't claim that the solution is general, but it "Works For Me" (tm).

INSERT INTO DB1.dbo.TempTable
SELECT * FROM DB2.dbo.TempTable

If we use this query it will return Primary key error.... So better to choose which columns need to be moved, like

INSERT INTO db1.dbo.TempTable // (List of columns here)
SELECT (Same list of columns here)
FROM db2.dbo.TempTable

What about this simple snippet, based on a standard script command (echo):

# set mac osx's terminal title to "My Title"
echo -n -e "\033]0;My Title\007"

Yes, use HashMap ... but in a specialised way: the trap I foresee in trying to use a HashMap as a pseudo-Set is the possible confusion between "actual" elements of the Map/Set, and "candidate" elements, i.e. elements used to test whether an equal element is already present. This is far from foolproof, but nudges you away from the trap:

class SelfMappingHashMap<V> extends HashMap<V, V>{
    @Override
    public String toString(){
        // otherwise you get lots of "... object1=object1, object2=object2..." stuff
        return keySet().toString();
    }

    @Override
    public V get( Object key ){
        throw new UnsupportedOperationException( "use tryToGetRealFromCandidate()");
    }

    @Override
    public V put( V key, V value ){
       // thorny issue here: if you were indavertently to `put`
       // a "candidate instance" with the element already in the `Map/Set`: 
       // these will obviously be considered equivalent 
       assert key.equals( value );
       return super.put( key, value );
    }

    public V tryToGetRealFromCandidate( V key ){
        return super.get(key);
    }
}

Then do this:

SelfMappingHashMap<SomeClass> selfMap = new SelfMappingHashMap<SomeClass>();
...
SomeClass candidate = new SomeClass();
if( selfMap.contains( candidate ) ){
    SomeClass realThing = selfMap.tryToGetRealFromCandidate( candidate );
    ...
    realThing.useInSomeWay()...
}

But... you now want the candidate to self-destruct in some way unless the programmer actually immediately puts it in the Map/Set... you'd want contains to "taint" the candidate so that any use of it unless it joins the Map makes it "anathema". Perhaps you could make SomeClass implement a new Taintable interface.

A more satisfactory solution is a GettableSet, as below. However, for this to work you have either to be in charge of the design of SomeClass in order to make all constructors non-visible (or... able and willing to design and use a wrapper class for it):

public interface NoVisibleConstructor {
    // again, this is a "nudge" technique, in the sense that there is no known method of 
    // making an interface enforce "no visible constructor" in its implementing classes 
    // - of course when Java finally implements full multiple inheritance some reflection 
    // technique might be used...
    NoVisibleConstructor addOrGetExisting( GettableSet<? extends NoVisibleConstructor> gettableSet );
};

public interface GettableSet<V extends NoVisibleConstructor> extends Set<V> {
    V getGenuineFromImpostor( V impostor ); // see below for naming
}

Implementation:

public class GettableHashSet<V extends NoVisibleConstructor> implements GettableSet<V> {
    private Map<V, V> map = new HashMap<V, V>();

    @Override
    public V getGenuineFromImpostor(V impostor ) {
        return map.get( impostor );
    }

    @Override
    public int size() {
        return map.size();
    }

    @Override
    public boolean contains(Object o) {
        return map.containsKey( o );
    }

    @Override
    public boolean add(V e) {
        assert e != null;
        V result = map.put( e,  e );
        return result != null;
    }

    @Override
    public boolean remove(Object o) {
        V result = map.remove( o );
        return result != null;
    }

    @Override
    public boolean addAll(Collection<? extends V> c) {
        // for example:
        throw new UnsupportedOperationException();
    }

    @Override
    public void clear() {
        map.clear();
    }

    // implement the other methods from Set ...
}

Your NoVisibleConstructor classes then look like this:

class SomeClass implements NoVisibleConstructor {

    private SomeClass( Object param1, Object param2 ){
        // ...
    }

    static SomeClass getOrCreate( GettableSet<SomeClass> gettableSet, Object param1, Object param2 ) {
        SomeClass candidate = new SomeClass( param1, param2 );
        if (gettableSet.contains(candidate)) {
            // obviously this then means that the candidate "fails" (or is revealed
            // to be an "impostor" if you will).  Return the existing element:
            return gettableSet.getGenuineFromImpostor(candidate);
        }
        gettableSet.add( candidate );
        return candidate;
    }

    @Override
    public NoVisibleConstructor addOrGetExisting( GettableSet<? extends NoVisibleConstructor> gettableSet ){
       // more elegant implementation-hiding: see below
    }
}

PS one technical issue with such a NoVisibleConstructor class: it may be objected that such a class is inherently final, which may be undesirable. Actually you could always add a dummy parameterless protected constructor:

protected SomeClass(){
    throw new UnsupportedOperationException();
}

... which would at least let a subclass compile. You'd then have to think about whether you need to include another getOrCreate() factory method in the subclass.

Final step is an abstract base class (NB "element" for a list, "member" for a set) like this for your set members (when possible - again, scope for using a wrapper class where the class is not under your control, or already has a base class, etc.), for maximum implementation-hiding:

public abstract class AbstractSetMember implements NoVisibleConstructor {
    @Override
    public NoVisibleConstructor
            addOrGetExisting(GettableSet<? extends NoVisibleConstructor> gettableSet) {
        AbstractSetMember member = this;
        @SuppressWarnings("unchecked") // unavoidable!
        GettableSet<AbstractSetMembers> set = (GettableSet<AbstractSetMember>) gettableSet;
        if (gettableSet.contains( member )) {
            member = set.getGenuineFromImpostor( member );
            cleanUpAfterFindingGenuine( set );
        } else {
            addNewToSet( set );
        }
        return member;
    }

    abstract public void addNewToSet(GettableSet<? extends AbstractSetMember> gettableSet );
    abstract public void cleanUpAfterFindingGenuine(GettableSet<? extends AbstractSetMember> gettableSet );
}

... usage is fairly obvious (inside your SomeClass's static factory method):

SomeClass setMember = new SomeClass( param1, param2 ).addOrGetExisting( set );

I'm guessing that when you enter a value into the totals field that value expression somehow gets overwritten.

However, you can take an alternative approach: Create a field for the total value and when either one or two changes update that field.

<li>Total <input type="text" ng-model="total">{{total}}</li>

And change the javascript:

function TodoCtrl($scope) {
    $scope.$watch('one * two', function (value) {
        $scope.total = value;
    });
}

Example fiddle here.

command = "ps -A | grep 'process_name'"
output = subprocess.check_output(["bash", "-c", command])

Then, paste the below code at the end. Full disclosure: This is just a direct copy & paste of the relevant bits of the above mentioned file taken from Centos 7.

Tested on MacOS and Ubuntu 18.04.

I make a static function. Its more efficient i think.

public static String file2Base64(String filePath) {
        FileInputStream fis = null;
        String base64String = "";
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        try {
            fis = new FileInputStream(filePath);
            byte[] buffer = new byte[1024 * 100];
            int count = 0;
            while ((count = fis.read(buffer)) != -1) {
                bos.write(buffer, 0, count);
            }
            fis.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
        base64String = Base64.encodeToString(bos.toByteArray(), Base64.DEFAULT);
        return base64String;

    }

Simple and easier!

In my case, i made separate method for local files, in this file: src/Illuminate/Filesystem/FilesystemAdapter.php

    /**
 * Get the local path for the given filename.
 * @param $path
 * @return string
 */
public function localPath($path)
{
    $adapter = $this->driver->getAdapter();
    if ($adapter instanceof LocalAdapter) {
        return $adapter->getPathPrefix().$path;
    } else {
        throw new RuntimeException('This driver does not support retrieving local path');
    }
}

then, i create pull request to framework, but it still not merged into main core yet: https://github.com/laravel/framework/pull/13605 May be someone merge this one))

As of June 2019 this setting can be found through searching 'Panel' - if you want to change the default there is an option for it as shown in the screenshot:

You can use methodsolver to find Ruby functions.

Here is a small script,

require 'methodsolver'

solve { a = [1,2,3]; a.____(0) == [0,1,2,3] }

Running this prints

You can install methodsolver using

gem install methodsolver

Notepad++ changed in the past couple of years, and it requires a few extra steps to set up a dark theme.

The answer by Amit-IO is good, but the example theme that is needed has stopped being maintained. The DraculaTheme is active. Just download the XML and put it in a themes folder. You may need Admin access in Windows.

@Jk1's answer is fine, but Mockito also allows for more succinct injection using annotations:

@InjectMocks MyClass myClass; //@InjectMocks automatically instantiates too
@Mock MyInterface myInterface

But regardless of which method you use, the annotations are not being processed (not even your @Mock) unless you somehow call the static MockitoAnnotation.initMocks() or annotate the class with @RunWith(MockitoJUnitRunner.class).

If you are using NumPy (as in ludaavic's answer), for large arrays you'll probably want to use NumPy's sum function rather than Python's builtin sum for a significant speedup -- e.g., a >1000x speedup for 10 million element arrays on my laptop:

>>> import numpy as np
>>> ten_million = 10 * 1000 * 1000
>>> x, y = (np.random.randn(ten_million) for _ in range(2))
>>> %timeit sum(x > y)  # time Python builtin sum function
1 loops, best of 3: 24.3 s per loop
>>> %timeit (x > y).sum()  # wow, that was really slow! time NumPy sum method
10 loops, best of 3: 18.7 ms per loop
>>> %timeit np.sum(x > y)  # time NumPy sum function
10 loops, best of 3: 18.8 ms per loop

(above uses IPython's %timeit "magic" for timing)

This worked for me :

select option {
   color: black;
}
select:not(:checked) {
   color: gray;
}

In ST2 there's a package you can install called Default FileType which does just that.

More info here.

If you are trying to keep a list of lists (similar to python's list.append()) then this might work:

a <- list(1,2,3)
b <- list(4,5,6)
c <- append(list(a), list(b))

> c
[[1]]
[[1]][[1]]
[1] 1

[[1]][[2]]
[1] 2

[[1]][[3]]
[1] 3


[[2]]
[[2]][[1]]
[1] 4

[[2]][[2]]
[1] 5

[[2]][[3]]
[1] 6

Changing the first letter to uppercase on the file's name and class name works.

file: controllers/Login.php

class: class Login extends CI_Controller { ... }

The file name, as the class name, should starts with capital letter. This rule applys to models too.

Edit your script locally, then pipe it into ssh, e.g.

cat commands-to-execute-remotely.sh | ssh blah_server

where commands-to-execute-remotely.sh looks like your list above:

ls some_folder
./someaction.sh
pwd;

You might also try an elseif.

x <- 1
if (x ==1){
    print('same')
} else if (x > 1){
    print('bigger')
} else {
    print('smaller')
}

Here is another, in my opinion even simpler solution using a flex wrapper:

HTML:

<div class="wrapper">
  <p>Text</p>
  <div class="line"></div>
</div>

CSS:

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

.line {
  border-top: 1px solid grey;
  flex-grow: 1;
  margin: 0 10px;
}

JSFiddle

If you have jQuery loaded on the page, you can execute the following javascript command:

"$('#" + element_id + "').click()"

Example using python executor:

driver.execute_script("$('#%s').click()" % element_id)

Pandas magic at work. All logic is out.

The error message "ValueError: If using all scalar values, you must pass an index" Says you must pass an index.

This does not necessarily mean passing an index makes pandas do what you want it to do

When you pass an index, pandas will treat your dictionary keys as column names and the values as what the column should contain for each of the values in the index.

a = 2
b = 3
df2 = pd.DataFrame({'A':a,'B':b}, index=[1])

    A   B
1   2   3

Passing a larger index:

df2 = pd.DataFrame({'A':a,'B':b}, index=[1, 2, 3, 4])

    A   B
1   2   3
2   2   3
3   2   3
4   2   3

An index is usually automatically generated by a dataframe when none is given. However, pandas does not know how many rows of 2 and 3 you want. You can however be more explicit about it

df2 = pd.DataFrame({'A':[a]*4,'B':[b]*4})
df2

    A   B
0   2   3
1   2   3
2   2   3
3   2   3

The default index is 0 based though.

I would recommend always passing a dictionary of lists to the dataframe constructor when creating dataframes. It's easier to read for other developers. Pandas has a lot of caveats, don't make other developers have to experts in all of them in order to read your code.

Look at this https://dev.to/risafj/beginner-s-guide-to-oauth-understanding-access-tokens-and-authorization-codes-2988

$clientid = "xxxxxxx.apps.googleusercontent.com";
$clientsecret = "xxxxxxxxxxxxxxxxxxxxx";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.googleapis.com/oauth2/v4/token");

curl_setopt($ch, CURLOPT_URL, "https://www.googleapis.com/oauth2/v4/token");
curl_setopt($ch, CURLOPT_POST, 1);

Bear in Mind to add the redirect_uri Domain to your Domains in your Google Console: https://console.cloud.google.com/apis/credentials in the Tab "OAuth 2.0-Client-IDs". There you find also your Client-ID and Client-Secret.

It's true, they are both - or more precisely, they are "inline block" elements. This means that they flow inline like text, but also have a width and height like block elements.

To accomodate both data scenarios you have, you will want to use this:

datevalue(text(a2,"mm/dd/yyyy"))

That will give you the date number representation for a cell that Excel has in date, or in text datatype.

Here's a modified version of Hors answer, works slightly better for my case, as it strips out the base directory that is passed as it goes, and has a recursive switch that can be set to false which is also handy. Plus to make the output more readable, I've separated the file and subdirectory files, so the files are added first then the subdirectory files (see result for what I mean.)

I tried a few other methods and suggestions around and this is what I ended up with. I had another working method already that was very similar, but seemed to fail where there was a subdirectory with no files but that subdirectory had a subsubdirectory with files, it didn't scan the subsubdirectory for files - so some answers may need to be tested for that case.)... anyways thought I'd post my version here too in case someone is looking...

function get_filelist_as_array($dir, $recursive = true, $basedir = '', $include_dirs = false) {
    if ($dir == '') {return array();} else {$results = array(); $subresults = array();}
    if (!is_dir($dir)) {$dir = dirname($dir);} // so a files path can be sent
    if ($basedir == '') {$basedir = realpath($dir).DIRECTORY_SEPARATOR;}

    $files = scandir($dir);
    foreach ($files as $key => $value){
        if ( ($value != '.') && ($value != '..') ) {
            $path = realpath($dir.DIRECTORY_SEPARATOR.$value);
            if (is_dir($path)) {
                // optionally include directories in file list
                if ($include_dirs) {$subresults[] = str_replace($basedir, '', $path);}
                // optionally get file list for all subdirectories
                if ($recursive) {
                    $subdirresults = get_filelist_as_array($path, $recursive, $basedir, $include_dirs);
                    $results = array_merge($results, $subdirresults);
                }
            } else {
                // strip basedir and add to subarray to separate file list
                $subresults[] = str_replace($basedir, '', $path);
            }
        }
    }
    // merge the subarray to give the list of files then subdirectory files
    if (count($subresults) > 0) {$results = array_merge($subresults, $results);}
    return $results;
}

I suppose one thing to be careful of it not to pass a $basedir value to this function when calling it... mostly just pass the $dir (or passing a filepath will work now too) and optionally $recursive as false if and as needed. The result:

[0] => demo-image.png
[1] => filelist.php
[2] => tile.png
[3] => 2015\header.png
[4] => 2015\08\background.jpg

Enjoy! Okay, back to the program I'm actually using this in...

UPDATE Added extra argument for including directories in the file list or not (remembering other arguments will need to be passed to use this.) eg.

$results = get_filelist_as_array($dir, true, '', true);

VB6 Installs just fine on Windows 7 (and Windows 8 / Windows 10) with a few caveats.

Here is how to install it:

• Before proceeding with the installation process below, create a zero-byte file in C:\Windows called MSJAVA.DLL. The setup process will look for this file, and if it doesn't find it, will force an installation of old, old Java, and require a reboot. By creating the zero-byte file, the installation of moldy Java is bypassed, and no reboot will be required.
• Turn off UAC.
• Insert Visual Studio 6 CD.
• Exit from the Autorun setup.
• Browse to the root folder of the VS6 CD.
• Right-click SETUP.EXE, select Run As Administrator.
• On this and other Program Compatibility Assistant warnings, click Run Program.
• Click Next.
• Click "I accept agreement", then Next.
• Enter name and company information, click Next.
• Select Custom Setup, click Next.
• Click Continue, then Ok.
• Setup will "think to itself" for about 2 minutes. Processing can be verified by starting Task Manager, and checking the CPU usage of ACMSETUP.EXE.
• On the options list, select the following:
  • Microsoft Visual Basic 6.0
  • ActiveX
  • Data Access
  • Graphics
  • All other options should be unchecked.
• Click Continue, setup will continue.
• Finally, a successful completion dialog will appear, at which click Ok. At this point, Visual Basic 6 is installed.
• If you do not have the MSDN CD, clear the checkbox on the next dialog, and click next. You'll be warned of the lack of MSDN, but just click Yes to accept.
• Click Next to skip the installation of Installshield. This is a really old version you don't want anyway.
• Click Next again to skip the installation of BackOffice, VSS, and SNA Server. Not needed!
• On the next dialog, clear the checkbox for "Register Now", and click Finish.
• The wizard will exit, and you're done. You can find VB6 under Start, All Programs, Microsoft Visual Studio 6. Enjoy!
• Turn On UAC again

• You might notice after successfully installing VB6 on Windows 7 that working in the IDE is a bit, well, sluggish. For example, resizing objects on a form is a real pain.
• After installing VB6, you'll want to change the compatibility settings for the IDE executable.
• Using Windows Explorer, browse the location where you installed VB6. By default, the path is C:\Program Files\Microsoft Visual Studio\VB98\
• Right click the VB6.exe program file, and select properties from the context menu.
• Click on the Compatibility tab.
• Place a check in each of these checkboxes:
• Run this program in compatibility mode for Windows XP (Service Pack 3)
  • Disable Visual Themes
  • Disable Desktop Composition
  • Disable display scaling on high DPI settings
  • If you have UAC turned on, it is probably advisable to check the 'Run this program as an Administrator' box

After changing these settings, fire up the IDE, and things should be back to normal, and the IDE is no longer sluggish.

Edit: Updated dead link to point to a different page with the same instructions

Edit: Updated the answer with the actual instructions in the post as the link kept dying

While the example works, its not the correct way to handle the streams...

You need to ensure the closing of the files/streams with the using clause.. Also, add try/catch to handle IO errors...

       public void DownloadAll()
    {
        string host = @"sftp.domain.com";
        string username = "myusername";
        string password = "mypassword";

        string remoteDirectory = "/RemotePath/";
        string localDirectory = @"C:\LocalDriveFolder\Downloaded\";

        using (var sftp = new SftpClient(host, username, password))
        {
            sftp.Connect();
            var files = sftp.ListDirectory(remoteDirectory);

            foreach (var file in files)
            {
                string remoteFileName = file.Name;
                if ((!file.Name.StartsWith(".")) && ((file.LastWriteTime.Date == DateTime.Today))

                    using (Stream file1 = File.OpenWrite(localDirectory + remoteFileName))
                    { 
                        sftp.DownloadFile(remoteDirectory + remoteFileName, file1);
                    }
            }

        }
    }

similar to R0byn's experience, i was experimenting with a Powerpoint slide presentation and dumped out the main body of text on the slide, finding that all the places where one would typically find carriage return (ASCII 13/0x0d/^M) or line feed/new line (ASCII 10/0x0a/^J) characters, it uses vertical tab (ASCII 11/0x0b/^K) instead, presumably for the exact reason that dan04 described above for Word: to serve as a "newline" while staying within the same paragraph. good question though as i totally thought this character would be as useless as a teletype terminal today.

The answer is yes.

Global Roboto light for TextView and Button classes:

<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:textViewStyle">@style/RobotoTextViewStyle</item>
    <item name="android:buttonStyle">@style/RobotoButtonStyle</item>
</style>

<style name="RobotoTextViewStyle" parent="android:Widget.TextView">
    <item name="android:fontFamily">sans-serif-light</item>
</style>

<style name="RobotoButtonStyle" parent="android:Widget.Holo.Button">
    <item name="android:fontFamily">sans-serif-light</item>
</style>

Just select the style you want from list themes.xml, then create your custom style based on the original one. At the end, apply the style as the theme of the application.

<application
    android:theme="@style/AppTheme" >
</application>

It will work only with built-in fonts like Roboto, but that was the question. For custom fonts (loaded from assets for example) this method will not work.

EDIT 08/13/15

If you're using AppCompat themes, remember to remove android: prefix. For example:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:textViewStyle">@style/RobotoTextViewStyle</item>
    <item name="buttonStyle">@style/RobotoButtonStyle</item>
</style>

Note the buttonStyle doesn't contain android: prefix, but textViewStyle must contain it.

We can never run out of alternatives of doing the same thing differently, right? I recently found this is pretty handy:

DECLARE
   BAR   VARCHAR2 (200) := '1,2,3';
BEGIN
   FOR FOO IN (    SELECT REGEXP_SUBSTR (BAR,
                                         '[^,]+',
                                         1,
                                         LEVEL)
                             TXT
                     FROM DUAL
               CONNECT BY REGEXP_SUBSTR (BAR,
                                         '[^,]+',
                                         1,
                                         LEVEL)
                             IS NOT NULL)
   LOOP
      DBMS_OUTPUT.PUT_LINE (FOO.TXT);
   END LOOP;
END;

Outputs:

1
2
3

The other solution is attaching the image as attachment and then referencing it html code using cid.

HTML Code:

<html>
    <head>
    </head>
    <body>
        <img width=100 height=100 id="1" src="cid:Logo.jpg">
    </body>
</html>

C# Code:

EmailMessage email = new EmailMessage(service);
email.Subject = "Email with Image";
email.Body = new MessageBody(BodyType.HTML, html);
email.ToRecipients.Add("[email protected]");
string file = @"C:\Users\acv\Pictures\Logo.jpg";
email.Attachments.AddFileAttachment("Logo.jpg", file);
email.Attachments[0].IsInline = true;
email.Attachments[0].ContentId = "Logo.jpg";
email.SendAndSaveCopy();

If you need path only this is the most straightforward way:

PathOnly = ThisWorkbook.Path

You can disable the background's click-to-close behavior and make this the default for all your modals by adding this JavaScript to your page (make sure it is executed after jQuery and Bootstrap JS are loaded):

$(function() {
    $.fn.modal.Constructor.DEFAULTS.backdrop = 'static';
});

Start from index.html remove all # from <a href="#/aboutus">About Us</a> so it must look like <a href="/aboutus">About Us</a>.Now in head tag of index.html write <base href="/"> just after last meta tag.

Now in your routing js inject $locationProvider and write $locatonProvider.html5Mode(true); Something Like This:-

app.config(function ($routeProvider, $locationProvider) {
    $routeProvider
        .when("/home", {
            templateUrl: "Templates/home.html",
            controller: "homeController"
        })
            .when("/aboutus",{templateUrl:"Templates/aboutus.html"})
            .when("/courses", {
                templateUrl: "Templates/courses.html",
                controller: "coursesController"
            })
            .when("/students", {
                templateUrl: "Templates/students.html",
                controller: "studentsController"
            })
        $locationProvider.html5Mode(true);
    });

• For those using pandas.DataFrame.plot(), matplotlib.axes.Axes is returned when creating a plot from a dataframe. As such, the dataframe plot can be assigned to a variable, ax, which enables the usage of the associated formatting methods.
• The default plotting backend for pandas, is matplotlib.

import pandas as pd

# test dataframe
data = {'a': range(20), 'date': pd.bdate_range('2021-01-09', freq='D', periods=20)}
df = pd.DataFrame(data)

# plot the dataframe and assign the returned axes
ax = df.plot(x='date', color='green', ylabel='values', xlabel='date', figsize=(8, 6))

# set various colors
ax.spines['bottom'].set_color('blue')
ax.spines['top'].set_color('red') 
ax.spines['right'].set_color('magenta')
ax.spines['left'].set_color('orange')
ax.xaxis.label.set_color('purple')
ax.yaxis.label.set_color('silver')
ax.tick_params(colors='red', which='both')  # 'both' refers to minor and major axes

Here is the full program

import java.util.concurrent.TimeUnit;

public class Milliseconds {

public static void main(String[] args) {
    long milliseconds = 1000000;

    // long minutes = (milliseconds / 1000) / 60;
    long minutes = TimeUnit.MILLISECONDS.toMinutes(milliseconds);

    // long seconds = (milliseconds / 1000);
    long seconds = TimeUnit.MILLISECONDS.toSeconds(milliseconds);

    System.out.format("%d Milliseconds = %d minutes\n", milliseconds, minutes );
    System.out.println("Or");
    System.out.format("%d Milliseconds = %d seconds", milliseconds, seconds );

}
}

I found this program here "Link" there it is explained in detail.

For those of us still working with older browsers, here's some extended backwards compatibility:

<div style="text-align: center;">
    <div style="display:-moz-inline-stack; display:inline-block; zoom:1; *display:inline; text-align: left;">
        Line 1: Testing<br>
        Line 2: More testing<br>
        Line 3: Even more testing<br>
    </div>
</div>

Simplest Kotlin solution using extension functions:

fun String.isEmailValid() =
            Pattern.compile(
                    "[a-zA-Z0-9\\+\\.\\_\\%\\-\\+]{1,256}" +
                            "\\@" +
                            "[a-zA-Z0-9][a-zA-Z0-9\\-]{0,64}" +
                            "(" +
                            "\\." +
                            "[a-zA-Z0-9][a-zA-Z0-9\\-]{0,25}" +
                            ")+"
            ).matcher(this).matches()

and then you can validate like this:

"[email protected]".isEmailValid()

If you are in kotlin-multiplatform without access to Pattern, this is the equivalent:

fun String.isValidEmail() = Regex(emailRegexStr).matches(this)

Simplest way is here:

1. Remove even lines and write it in some temp file 1.
2. Remove odd lines and write it in some temp file 2.
3. Combine two files in one by using paste command with -d (means delete space)

sed '0~2d' file > 1 && sed '1~2d' file > 2 && paste -d " " 1 2

You can also use the arrow library. This is a simple example:

from datetime import datetime
import arrow

start = datetime(2014, 1, 17)
end = datetime(2014, 6, 20)

for d in arrow.Arrow.range('month', start, end):
    print d.month, d.format('MMMM')

This will print:

1 January
2 February
3 March
4 April
5 May
6 June

Hope this helps!

In the second you can access the attributes of the exception object:

>>> def catch():
...     try:
...         asd()
...     except Exception as e:
...         print e.message, e.args
... 
>>> catch()
global name 'asd' is not defined ("global name 'asd' is not defined",)

But it doesn't catch BaseException or the system-exiting exceptions SystemExit, KeyboardInterrupt and GeneratorExit:

>>> def catch():
...     try:
...         raise BaseException()
...     except Exception as e:
...         print e.message, e.args
... 
>>> catch()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 3, in catch
BaseException

Which a bare except does:

>>> def catch():
...     try:
...         raise BaseException()
...     except:
...         pass
... 
>>> catch()
>>> 

See the Built-in Exceptions section of the docs and the Errors and Exceptions section of the tutorial for more info.

this bellow solution worked for me

$result_encr="##Sƒ";

iconv("cp1252", "utf-8//IGNORE", $result_encr);

Another good solution would be using Android's LiveData with MVVM architecture. You would define a LiveData object inside your ViewModel and observe it in your fragment, and when LiveData value is changed, it would notify your observer (fragment in this case) only if your fragment is in active state, so it would be guaranteed that you would make your UI works and access the activity only when your fragment is in active state. This is one advantage that comes with LiveData

Of course when this question was first asked, there was no LiveData. I am leaving this answer here because as I see, there is still this problem and it could be helpful to someone.

You can use a WScript object and call the Sleep method on it:

Set WScript = CreateObject("WScript.Shell")
WScript.Sleep 2000 'Sleeps for 2 seconds

Another option is to import and use the WinAPI function directly (only works in VBA, thanks @Helen):

Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Sleep 2000

use function "printPreview(binaryPDFData)" to get print preview dialog of binary pdf data.

printPreview = (data, type = 'application/pdf') => {
    let blob = null;
    blob = this.b64toBlob(data, type);
    const blobURL = URL.createObjectURL(blob);
    const theWindow = window.open(blobURL);
    const theDoc = theWindow.document;
    const theScript = document.createElement('script');
    function injectThis() {
        window.print();
    }
    theScript.innerHTML = `window.onload = ${injectThis.toString()};`;
    theDoc.body.appendChild(theScript);
};

b64toBlob = (content, contentType) => {
    contentType = contentType || '';
    const sliceSize = 512;
     // method which converts base64 to binary
    const byteCharacters = window.atob(content); 

    const byteArrays = [];
    for (let offset = 0; offset < byteCharacters.length; offset += sliceSize) {
        const slice = byteCharacters.slice(offset, offset + sliceSize);
        const byteNumbers = new Array(slice.length);
        for (let i = 0; i < slice.length; i++) {
            byteNumbers[i] = slice.charCodeAt(i);
        }
        const byteArray = new Uint8Array(byteNumbers);
        byteArrays.push(byteArray);
    }
    const blob = new Blob(byteArrays, {
        type: contentType
    }); // statement which creates the blob
    return blob;
};

Auto incrementing primary key in postgresql:

Step 1, create your table:

CREATE TABLE epictable
(
    mytable_key    serial primary key,
    moobars        VARCHAR(40) not null,
    foobars        DATE
);

Step 2, insert values into your table like this, notice that mytable_key is not specified in the first parameter list, this causes the default sequence to autoincrement.

insert into epictable(moobars,foobars) values('delicious moobars','2012-05-01')
insert into epictable(moobars,foobars) values('worldwide interblag','2012-05-02')

Step 3, select * from your table:

el@voyager$ psql -U pgadmin -d kurz_prod -c "select * from epictable"

Step 4, interpret the output:

mytable_key  |        moobars        |  foobars   
-------------+-----------------------+------------
           1 | delicious moobars     | 2012-05-01
           2 | world wide interblags | 2012-05-02
(2 rows)

Observe that mytable_key column has been auto incremented.

ProTip:

You should always be using a primary key on your table because postgresql internally uses hash table structures to increase the speed of inserts, deletes, updates and selects. If a primary key column (which is forced unique and non-null) is available, it can be depended on to provide a unique seed for the hash function. If no primary key column is available, the hash function becomes inefficient as it selects some other set of columns as a key.

Say you want to install Node 10,

Firstly, download and execute the Node.js 10.x installer:

curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -

This will add a source file for the official Node.js 10.x repo, grabs the signing key

Once the installer is done doing it’s thing, you will need to install (or upgrade) Node.js:

sudo apt install nodejs

Extending your code (assuming that the XML you want to send is in xmlString) :

String xmlString = "</xml>";
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpRequest = new HttpPost(this.url);
httpRequest.setHeader("Content-Type", "application/xml");
StringEntity xmlEntity = new StringEntity(xmlString);
httpRequest.setEntity(xmlEntity );
HttpResponse httpresponse = httpclient.execute(httppost);

To substantiate @deceze's claim that the default JSON encoding is UTF-8...

From IETF RFC4627:

JSON text SHALL be encoded in Unicode. The default encoding is UTF-8.

Since the first two characters of a JSON text will always be ASCII characters [RFC0020], it is possible to determine whether an octet stream is UTF-8, UTF-16 (BE or LE), or UTF-32 (BE or LE) by looking at the pattern of nulls in the first four octets.

      00 00 00 xx  UTF-32BE
      00 xx 00 xx  UTF-16BE
      xx 00 00 00  UTF-32LE
      xx 00 xx 00  UTF-16LE
      xx xx xx xx  UTF-8

Not sure if it's just me, but using .remove() doesn't seem to work if you are selecting by an id.

Ex: $("#my-element").remove();

I had to use the element's class instead, or nothing happened.

Ex: $(".my-element").remove();

Java has evolved since this issue was first brought up. You can match all manner of unicode space characters by using the \p{Zs} group.

Thus if you wanted to replace one or more exotic spaces with a plain space you could do this:

String txt = "whatever my string is";
txt.replaceAll("\\p{Zs}+", " ")

Also worth knowing, if you've used the trim() string function you should take a look at the (relatively new) strip(), stripLeading(), and stripTrailing() functions on strings. The can help you trim off all sorts of squirrely white space characters. For more information on what what space is included, see Java's Character.isWhitespace() function.

Null is not a 'problem'. It is an integral part of a complete modeling tool set. Software aims to model the complexity of the world and null bears its burden. Null indicates 'No data' or 'Unknown' in Java and the like. So it is appropriate to use nulls for these purposes. I don't prefer the 'Null object' pattern; I think it rise the 'who will guard the guardians' problem.
If you ask me what is the name of my girlfriend I'll tell you that I have no girlfriend. In the Java language I'll return null. An alternative would be to throw meaningful exception to indicate some problem that can't be (or don't want to be) solved right there and delegate it somewhere higher in the stack to retry or report data access error to the user.

1. For an 'unknown question' give 'unknown answer'. (Be null-safe where this is correct from business point of view) Checking arguments for null once inside a method before usage relieves multiple callers from checking them before a call.

   public Photo getPhotoOfThePerson(Person person) {
       if (person == null)
           return null;
       // Grabbing some resources or intensive calculation
       // using person object anyhow.
   }
   

   Previous leads to normal logic flow to get no photo of a non-existent girlfriend from my photo library.

   getPhotoOfThePerson(me.getGirlfriend())
   

   And it fits with new coming Java API (looking forward)

   getPhotoByName(me.getGirlfriend()?.getName())
   

   While it is rather 'normal business flow' not to find photo stored into the DB for some person, I used to use pairs like below for some other cases

   public static MyEnum parseMyEnum(String value); // throws IllegalArgumentException
   public static MyEnum parseMyEnumOrNull(String value);
   

   And don't loathe to type <alt> + <shift> + <j> (generate javadoc in Eclipse) and write three additional words for you public API. This will be more than enough for all but those who don't read documentation.

   /**
    * @return photo or null
    */
   

   or

   /**
    * @return photo, never null
    */
   

2. This is rather theoretical case and in most cases you should prefer java null safe API (in case it will be released in another 10 years), but NullPointerException is subclass of an Exception. Thus it is a form of Throwable that indicates conditions that a reasonable application might want to catch (javadoc)! To use the first most advantage of exceptions and separate error-handling code from 'regular' code (according to creators of Java) it is appropriate, as for me, to catch NullPointerException.

   public Photo getGirlfriendPhoto() {
       try {
           return appContext.getPhotoDataSource().getPhotoByName(me.getGirlfriend().getName());
       } catch (NullPointerException e) {
           return null;
       }
   }
   

   Questions could arise:

   Q. What if getPhotoDataSource() returns null?
   A. It is up to business logic. If I fail to find a photo album I'll show you no photos. What if appContext is not initialized? This method's business logic puts up with this. If the same logic should be more strict then throwing an exception it is part of the business logic and explicit check for null should be used (case 3). The new Java Null-safe API fits better here to specify selectively what implies and what does not imply to be initialized to be fail-fast in case of programmer errors.

   Q. Redundant code could be executed and unnecessary resources could be grabbed.
   A. It could take place if getPhotoByName() would try to open a database connection, create PreparedStatement and use the person name as an SQL parameter at last. The approach for an unknown question gives an unknown answer (case 1) works here. Before grabbing resources the method should check parameters and return 'unknown' result if needed.

   Q. This approach has a performance penalty due to the try closure opening.
   A. Software should be easy to understand and modify firstly. Only after this, one could think about performance, and only if needed! and where needed! (source), and many others).

   PS. This approach will be as reasonable to use as the separate error-handling code from "regular" code principle is reasonable to use in some place. Consider the next example:

   public SomeValue calculateSomeValueUsingSophisticatedLogic(Predicate predicate) {
       try {
           Result1 result1 = performSomeCalculation(predicate);
           Result2 result2 = performSomeOtherCalculation(result1.getSomeProperty());
           Result3 result3 = performThirdCalculation(result2.getSomeProperty());
           Result4 result4 = performLastCalculation(result3.getSomeProperty());
           return result4.getSomeProperty();
       } catch (NullPointerException e) {
           return null;
       }
   }
   
   public SomeValue calculateSomeValueUsingSophisticatedLogic(Predicate predicate) {
       SomeValue result = null;
       if (predicate != null) {
           Result1 result1 = performSomeCalculation(predicate);
           if (result1 != null && result1.getSomeProperty() != null) {
               Result2 result2 = performSomeOtherCalculation(result1.getSomeProperty());
               if (result2 != null && result2.getSomeProperty() != null) {
                   Result3 result3 = performThirdCalculation(result2.getSomeProperty());
                   if (result3 != null && result3.getSomeProperty() != null) {
                       Result4 result4 = performLastCalculation(result3.getSomeProperty());
                       if (result4 != null) {
                           result = result4.getSomeProperty();
                       }
                   }
               }
           }
       }
       return result;
   }
   

   PPS. For those fast to downvote (and not so fast to read documentation) I would like to say that I've never caught a null-pointer exception (NPE) in my life. But this possibility was intentionally designed by the Java creators because NPE is a subclass of Exception. We have a precedent in Java history when ThreadDeath is an Error not because it is actually an application error, but solely because it was not intended to be caught! How much NPE fits to be an Error than ThreadDeath! But it is not.

3. Check for 'No data' only if business logic implies it.

   public void updatePersonPhoneNumber(Long personId, String phoneNumber) {
       if (personId == null)
           return;
       DataSource dataSource = appContext.getStuffDataSource();
       Person person = dataSource.getPersonById(personId);
       if (person != null) {
           person.setPhoneNumber(phoneNumber);
           dataSource.updatePerson(person);
       } else {
           Person = new Person(personId);
           person.setPhoneNumber(phoneNumber);
           dataSource.insertPerson(person);
       }
   }
   

   and

   public void updatePersonPhoneNumber(Long personId, String phoneNumber) {
       if (personId == null)
           return;
       DataSource dataSource = appContext.getStuffDataSource();
       Person person = dataSource.getPersonById(personId);
       if (person == null)
           throw new SomeReasonableUserException("What are you thinking about ???");
       person.setPhoneNumber(phoneNumber);
       dataSource.updatePerson(person);
   }
   

   If appContext or dataSource is not initialized unhandled runtime NullPointerException will kill current thread and will be processed by Thread.defaultUncaughtExceptionHandler (for you to define and use your favorite logger or other notification mechanizm). If not set, ThreadGroup#uncaughtException will print stacktrace to system err. One should monitor application error log and open Jira issue for each unhandled exception which in fact is application error. Programmer should fix bug somewhere in initialization stuff.

I like to solve the lack of by reference in JavaScript like this example shows.

The essence of this is that you don't try to create a by reference. You instead use the return functionality and make it able to return multiple values. So there isn't any need to insert your values in arrays or objects.

var x = "First";
var y = "Second";
var z = "Third";

log('Before call:',x,y,z);
with (myFunc(x, y, z)) {x = a; y = b; z = c;} // <-- Way to call it
log('After call :',x,y,z);


function myFunc(a, b, c) {
  a = "Changed first parameter";
  b = "Changed second parameter";
  c = "Changed third parameter";
  return {a:a, b:b, c:c}; // <-- Return multiple values
}

function log(txt,p1,p2,p3) {
  document.getElementById('msg').innerHTML += txt + '<br>' + p1 + '<br>' + p2 + '<br>' + p3 + '<br><br>'
}

<div id='msg'></div>

strcat has the declaration:

char *strcat(char *dest, const char *src)

It expects 2 strings. While this compiles:

char str[1024] = "Hello World";
char tmp = '.';

strcat(str, tmp);

It will cause bad memory issues because strcat is looking for a null terminated cstring. You can do this:

char str[1024] = "Hello World";
char tmp[2] = ".";

strcat(str, tmp);

Live example.

If you really want to append a char you will need to make your own function. Something like this:

void append(char* s, char c) {
        int len = strlen(s);
        s[len] = c;
        s[len+1] = '\0';
}

append(str, tmp)

Of course you may also want to check your string size etc to make it memory safe.

This worked for me. Tested in FF, Chrome, IE11, IE10

.row {
    width:99.99%;
}

use

location.reload();

or

window.location.reload();

Update as of npm 5:

As of npm 5.0.0, installed modules are added as a dependency by default, so the --save option is no longer needed. The other save options still exist and are listed in the documentation for npm install.

Original answer:

It won't do anything if you don't have a package.json file. Start by running npm init to create one. Then calls to npm install --save or npm install --save-dev or npm install --save-optional will update the package.json to list your dependencies.

If not using C++14, then I find below the simplest solution.

#define METHOD(NAME, ...) auto NAME __VA_ARGS__ -> decltype(m_T.r##NAME) { return m_T.r##NAME; }
template<typename T>
struct Reverse
{
  T& m_T;

  METHOD(begin());
  METHOD(end());
  METHOD(begin(), const);
  METHOD(end(), const);
};
#undef METHOD

template<typename T>
Reverse<T> MakeReverse (T& t) { return Reverse<T>{t}; }

Demo.
It doesn't work for the containers/data-types (like array), which doesn't have begin/rbegin, end/rend functions.

java.time

I should like to contribute the modern answer. The SimpleDateFormat class is notoriously troublesome, and while it was reasonable to fight one’s way through with it when this question was asked six and a half years ago, today we have much better in java.time, the modern Java date and time API. SimpleDateFormat and its friend Date are now considered long outdated, so don’t use them anymore.

    DateTimeFormatter monthFormatter = DateTimeFormatter.ofPattern("MM/uuuu");
    String dateformat = "2012-11-17T00:00:00.000-05:00";
    OffsetDateTime dateTime = OffsetDateTime.parse(dateformat);
    String monthYear = dateTime.format(monthFormatter);
    System.out.println(monthYear);

Output:

11/2012

I am exploiting the fact that your string is in ISO 8601 format, the international standard, and that the classes of java.time parse this format as their default, that is, without any explicit formatter. It’s stil true what the other answers say, you need to parse the original string first, then format the resulting date-time object into a new string. Usually this requires two formatters, only in this case we’re lucky and can do with just one formatter.

What went wrong in your code

• As others have said, SimpleDateFormat.format cannot accept a String argument, also when the parameter type is declared to be Object.
• Because of the exception you didn’t get around to discovering: there is also a bug in your format pattern string, mm/yyyy. Lowercase mm os for minute of the hour. You need uppercase MM for month.
• Finally the Java naming conventions say to use a lowercase first letter in variable names, so use lowercase m in monthYear (also because java.time includes a MonthYear class with uppercase M, so to avoid confusion).

You asked for C#. Trivial example:

    private static readonly Singleton _singleton = new Singleton();

    public static Singleton GetSingleton()
    {
        return _singleton;

The error arises because gnuplot is trying to interpret the word "plot" as the filename to plot, but you haven't assigned any strings to a variable named "plot" (which is good – that would be super confusing).

Another simple way,

final Calendar today = Calendar.getInstance();
        today.setTime(new Date());
        today.clear(Calendar.HOUR_OF_DAY);
        today.clear(Calendar.HOUR);
        today.clear(Calendar.MINUTE);
        today.clear(Calendar.SECOND);
        today.clear(Calendar.MILLISECOND);

Not knowing exactly what you want to do... but still here's a possible solution.

Create a scope with a '&'-property in the local scope. It "provides a way to execute an expression in the context of the parent scope" (see the directive documentation for details).

I also noticed that you used a shorthand linking function and shoved in object attributes in there. You can't do that. It is more clear (imho) to just return the directive-definition object. See my code below.

Here's a code sample and a fiddle.

<div ng-app="myApp">
<div ng-controller="myController">
    <div my-method='theMethodToBeCalled'>Click me</div>
</div>
</div>

<script>

   var app = angular.module('myApp',[]);

   app.directive("myMethod",function($parse) {
       var directiveDefinitionObject = {
         restrict: 'A',
         scope: { method:'&myMethod' },
         link: function(scope,element,attrs) {
            var expressionHandler = scope.method();
            var id = "123";

            $(element).click(function( e, rowid ) {
               expressionHandler(id);
            });
         }
       };
       return directiveDefinitionObject;
   });

   app.controller("myController",function($scope) {
      $scope.theMethodToBeCalled = function(id) { 
          alert(id); 
      };
   });

</script>

To verify and list the fingerprint of the key (without importing it into the keyring first), type

gpg --with-fingerprint <filename>

Edit: on Ubuntu 18.04 (gpg 2.2.4) the fingerprint isn't show with the above command. Use the --with-subkey-fingerprint option instead

gpg --with-subkey-fingerprint <filename>

(function(undefined){
    var charsToReplace = {
        '&': '&',
        '<': '&lt;',
        '>': '&gt;'
    };

    var replaceReg = new RegExp("[" + Object.keys(charsToReplace).join("") + "]", "g");
    var replaceFn = function(tag){ return charsToReplace[tag] || tag; };

    var replaceRegF = function(replaceMap) {
        return (new RegExp("[" + Object.keys(charsToReplace).concat(Object.keys(replaceMap)).join("") + "]", "gi"));
    };
    var replaceFnF = function(replaceMap) {
        return function(tag){ return replaceMap[tag] || charsToReplace[tag] || tag; };
    };

    String.prototype.htmlEscape = function(replaceMap) {
        if (replaceMap === undefined) return this.replace(replaceReg, replaceFn);
        return this.replace(replaceRegF(replaceMap), replaceFnF(replaceMap));
    };
})();

No global variables, some memory optimization. Usage:

"some<tag>and&symbol©".htmlEscape({'©': '&copy;'})

result is:

"some<tag>and&symbol©"
