Programs & Examples On #Tomcat5.5

just put all apache comons jar and file upload jar in lib folder of tomcat

There are several good answers on here but I wanted to add one since it may be helpful for users like me who have Tomcat installed as a service on a Windows machine.

Option 3 here: http://www.codejava.net/servers/tomcat/4-ways-to-change-jre-for-tomcat

Basically, open tomcatw.exe and point Tomcat to the version of the JVM you need to use then restart the service. Ensure your deployed applications still work as well.

Try to set the property when starting JVM, for example, add -Djava.net.preferIPv4Stack=true.

You can't set it when code running, as the java.net just read it when jvm starting.

And about the root cause, this article give some hint: Why do I need java.net.preferIPv4Stack=true only on some windows 7 systems?.

Before making any changes in Tomcat Server Location, you need to remove project(s) deployed on server.

To remove project: expand tomcat server in "Servers" view
right click and select remove

"saving" is something wholly different from changing paragraph content with jquery.

If you need to save changes you will have to write them to your server somehow (likely form submission along with all the security and input sanitizing that entails). If you have information that is saved on the server then you are no longer changing the content of a paragraph, you are drawing a paragraph with dynamic content (either from a database or a file which your server altered when you did the "saving").

Judging by your question, this is a topic on which you will have to do MUCH more research.

Input page (input.html):

<form action="/saveMyParagraph.php">
    <input name="pContent" type="text"></input>
</form>

Saving page (saveMyParagraph.php) and Ouput page (output.php):

Inserting Data Into a MySQL Database using PHP

here is my try to import database from cmd in xampp server the correct command for me is this you can change it with your requirements.and i also attached Errors that i face first time importing db from command line.you can see last command that i use and i paste it here also its working fro me.

mysql -h localhost -u root ovxsolut_windhs < C:\Users\eee\Downloads\ovxsolut_windhs.sql

for MySQL all (and 5.7)

SELECT LOWER(TRIM(BOTH 0x22 FROM TRIM(BOTH 0x20 FROM SUBSTRING(SUBSTRING(json_filed,LOCATE('\"ArrayItem\"',json_filed)+LENGTH('\"ArrayItem\"'),LOCATE(0x2C,SUBSTRING(json_filed,LOCATE('\"ArrayItem\"',json_filed)+LENGTH('\"ArrayItem\"')+1,LENGTH(json_filed)))),LOCATE(0x22,SUBSTRING(json_filed,LOCATE('\"ArrayItem\"',json_filed)+LENGTH('\"ArrayItem\"'),LOCATE(0x2C,SUBSTRING(json_filed,LOCATE('\"ArrayItem\"',json_filed)+LENGTH('\"ArrayItem\"')+1,LENGTH(json_filed))))),LENGTH(json_filed))))) AS result FROM `table`;

Use the abs function:

int sum=0;
for(Integer i : container)
  sum+=Math.abs(i);

Copy should be used for NSString. If it's Mutable, then it gets copied. If it's not, then it just gets retained. Exactly the semantics that you want in an app (let the type do what's best).

confirmed only that method work now:

newVersion = Jsoup.connect("https://play.google.com/store/apps/details?id=" + AcMainPage.this.getPackageName() + "&hl=it")
                        .timeout(30000)
                        .userAgent("Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-US; rv1.8.1.6) Gecko/20070725 Firefox/2.0.0.6")
                        .referrer("http://www.google.com")
                        .get()
                        .select(".hAyfc .htlgb")
                        .get(5)
                        .ownText();

Use "This is' it".replace("'", "\\'")

You can try the regex here to filter out the columns starting with "foo"

df.filter(regex='^foo*')

If you need to have the string foo in your column then

df.filter(regex='foo*')

would be appropriate.

For the next step, you can use

df[df.filter(regex='^foo*').values==1]

to filter out the rows where one of the values of 'foo*' column is 1.

A pure solution without jQuery:

Javascript (Head)

function chbg(color) {
    document.getElementById('b').style.backgroundColor = color;
}   

HTML (Body)

<div id="a" onmouseover="chbg('red')" onmouseout="chbg('white')">This is element a</div>
<div id="b">This is element b</div>

JSFiddle: http://jsfiddle.net/YShs2/

How about \A[a-z]*Id\z? [This makes characters before Id optional. Use \A[a-z]+Id\z if there needs to be one or more characters preceding Id.]

I have success with using the Chrome addon "Sharelatex". This online editor has great compability with most latex files, but it somewhat lacks configuration possibilities. www.sharelatex.com

To add to answer given by Anil, In symfony3, you can use $this->getUser() to determine if the user is logged in, a simple condition like if(!$this->getUser()) {} will do.

If you look at the source code which is available in base controller, it does the exact same thing defined by Anil.

I suggest to use sticky js it's have best option ever i have seen. nothing to do just ad this js on you

 https://raw.githubusercontent.com/garand/sticky/master/jquery.sticky.js

and use below code :

<script>
  $(document).ready(function(){
    $("#sticker").sticky({topSpacing:0});
  });
</script>

Its git repo: https://github.com/garand/sticky

Use powershell inside your bat file

PowerShell Remove-Item c:\scripts\* -include *.txt -exclude *test* -force -recurse

You can also exclude from removing some specific folder or file:

PowerShell Remove-Item C:/*  -Exclude WINDOWS,autoexec.bat -force -recurse

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):

letsago = "ID" + str(self.dirDesc.values())

However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:

>>>str({'a':1}.values())
'dict_values([1])'

If you REALLY needed to find the variable this way, you could use the eval function:

>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'

or the globals function:

class Foo(object):
    def __init__(self):
        super(Foo, self).__init__()
    def test(self, name):
        print(globals()[name])

foo = Foo()
bar = 'Hello World!'
foo.text('bar')

However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.

Your query should work for synonyms as well as the tables. However, you seem to expect indexes on views where there are not. Maybe is it materialized views ?

It looks to me, like you're working in windows in which case a new line character in not simply \n but rather \r\n

You can always get the correct new line character through System.getProperty("line.separator") for example.

Old fashioned way..

private static Date getDateWithMidnight(){
    long dateInMillis = new Date().getTime();
    return new Date(dateInMillis - dateInMillis%(1000*60*60*24) - TimeZone.getDefault().getOffset(dateInMillis));
}

$(document).ready(function () {



    $("#cust_zip").keypress(function (e) {
        //var z = document.createUserForm.cust_mobile1.value;
        //alert(z);
        if (e.which != 8 && e.which != 0 && (e.which < 48 || e.which > 57)) {

            $("#errmsgzip").html("Digits Only.").show().fadeOut(3000);
            return false;
        }
    });
});

fwrite($handle, "<br>"."\r\n");

Add this under

$password = $_POST['password'].PHP_EOL;

this. .

It's slow. It's platform dependent. It's insecure.

First: What it does. Calling "system" is literally like typing a command into the windows command prompt. There is a ton of setup and teardown for your application to make such a call - and the overhead is simply ridiculous.

What if a program called "pause" was placed into the user's PATH? Just calling system("pause") only guarantees that a program called "pause" is executed (hope that you don't have your executable named "pause"!)

Simply write your own "Pause()" function that uses _getch. OK, sure, _getch is platform dependent as well (note: it's defined in "conio.h") - but it's much nicer than system() if you are developing on Windows and it has the same effect (though it is your responsibility to provide the text with cout or so).

Basically: why introduce so many potential problems when you can simply add two lines of code and one include and get a much more flexible mechanism?

You can simply use the HTML onwheel attribute.

This option have no effects on scrolling over other elements of the page.

And add a listener for all inputs don't work in inputs dynamically created posteriorly.

Aditionaly, you can remove the input arrows with CSS.

input[type="number"]::-webkit-outer-spin-button, _x000D_
input[type="number"]::-webkit-inner-spin-button {_x000D_
    -webkit-appearance: none;_x000D_
    margin: 0;_x000D_
}_x000D_
input[type="number"] {_x000D_
    -moz-appearance: textfield;_x000D_
}

<input type="number" onwheel="this.blur()" />

You can call this method using the resultSet and the column name having Number type. It will either return the Integer value, or null. There will be no zeros returned for empty value in the database

private Integer getIntWithNullCheck(ResultSet rset, String columnName) {
    try {
        Integer value = rset.getInt(columnName);
        return rset.wasNull() ? null : value;
    } catch (Exception e) {
        return null;
    }
}

I know this is a little late, but I was also having this issue a while ago. This is what worked for me:

REALLY_GEM_UPDATE_SYSTEM=1 
sudo gem update --system
sudo gem install rails

Hope this helps anyone else having this issue :)

And for yet another option, I'd go with awk!

echo "foo bar <foo> bla 1 2 3.4" | awk '{ print $(NF-1), $NF; }'

This will split the input (I'm using STDIN here, but your input could easily be a file) on spaces, and then print out the last-but-one field, and then the last field. The $NF variables hold the number of fields found after exploding on spaces.

The benefit of this is that it doesn't matter if what precedes the last two fields changes, as long as you only ever want the last two it'll continue to work.

Branching off of Mohommad's answer:

str_years = [x for x in range(24)]
#[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23]

#Or, if you're starting with ints:
int_years = [int(x) for x in str_years]

#Formatted here
form_years = ["%02d" % x for x in int_years]

print(form_years)
#['00', '01', '02', '03', '04', '05', '06', '07', '08', '09', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20', '21', '22', '23']

webRTC or websockets? Why not use both.

When building a video/audio/text chat, webRTC is definitely a good choice since it uses peer to peer technology and once the connection is up and running, you do not need to pass the communication via a server (unless using TURN).

When setting up the webRTC communication you have to involve some sort of signaling mechanism. Websockets could be a good choice here, but webRTC is the way to go for the video/audio/text info. Chat rooms is accomplished in the signaling.

But, as you mention, not every browser supports webRTC, so websockets can sometimes be a good fallback for those browsers.

I had the same problem in my grails project. The Bug was, that i overwrite the getter method of a collection field. This returned always a new version of the collection in other thread.

class Entity {
    List collection

    List getCollection() {
        return collection.unique()
    }
}

The solution was to rename the getter method:

class Entity {
    List collection

    List getUniqueCollection() {
        return collection.unique()
    }
}

Why not try FROM_UNIXTIME(unix_timestamp, format)?

Try using FIND_IN_SET() function of MySql e.g.

SET @c = 'xxx,yyy,zzz';

SELECT * from countries 
WHERE FIND_IN_SET(countryname,@c);

Note: You don't have to SET variable in StoredProcedure if you are passing parameter with CSV values.

Even after adding @Autowire if your class is not a RestController or Configuration Class, the applicationContext object was coming as null. Tried Creating new class with below and it is working fine:

@Component
public class SpringContext implements ApplicationContextAware{

   private static ApplicationContext applicationContext;

   @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws 
     BeansException {
    this.applicationContext=applicationContext;
   }
 }

you can then implement a getter method in the same class as per your need to get the bean. Like:

    applicationContext.getBean(String serviceName,Interface.Class)

You can use GCD (in the example with a 10 second delay):

Swift 2

let triggerTime = (Int64(NSEC_PER_SEC) * 10)
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, triggerTime), dispatch_get_main_queue(), { () -> Void in
    self.functionToCall()
})

Swift 3 and Swift 4

DispatchQueue.main.asyncAfter(deadline: .now() + 10.0, execute: {
    self.functionToCall()
})

Swift 5 or Later

 DispatchQueue.main.asyncAfter(deadline: .now() + 10.0) {
        //call any function
    }

This will work i have tested myself.
It gives difference between sysdate and date fetched from column admitdate

  TABLE SCHEMA:
    CREATE TABLE "ADMIN"."DUESTESTING" 
    (   
  "TOTAL" NUMBER(*,0), 
"DUES" NUMBER(*,0), 
"ADMITDATE" TIMESTAMP (6), 
"DISCHARGEDATE" TIMESTAMP (6)
    )

EXAMPLE:
select TO_NUMBER(trunc(sysdate) - to_date(to_char(admitdate, 'yyyy-mm-dd'),'yyyy-mm-dd')) from admin.duestesting where total=300

If your question about <input type="date"> field, here is script for getting filed value="" attribute:

(new Date()).toISOString().split('T')[0]

You can use the Intl object (ecma-402) to get data-date-pattern="":

(new Intl.DateTimeFormat()).resolved.pattern // "M/d/y" for "en-US" in Google Chrome

And finnaly, to format date in current l10n, data-date="":

(new Intl.DateTimeFormat()).format(new Date());

Polyfill: https://github.com/andyearnshaw/Intl.js/issues/129

in visual studio 2012 or above, you can do like this

struct Foo { Foo(int x) { /* ... */  } };

struct Baz { 
     Foo foo[3];

     Baz() : foo() { }
};

Export (or datapump if you have 10g/11g) is the way to do it. Why not ask how to fix your problems with that rather than trying to find another way to do it?

Tips:

You can try to use

ctx.getSystemService("phone_msim")

instead of

ctx.getSystemService(Context.TELEPHONY_SERVICE)

If you have already tried Vaibhav's answer and telephony.getClass().getMethod() fails, above is what works for my Qualcomm mobile.

The solution for PyCharm would be to install a Makefile support plugin:

1. Open Preferences (cmd + ,)
2. Go to Plugins -> Marketplace
3. Search for Makefile support, install and restart the IDE.

This should fix the problem and provide a syntax for a makefile.

Why not use an object¹?

var dict = { "a": 1, "b": 2, "c": 3 };

Then you can update it like so

dict.a = 23;

or

dict["a"] = 23;

If you wan't to delete² a particular key, it's as simple as:

delete dict.a;

_{¹ See Objects vs arrays in Javascript for key/value pairs.
² See the delete operator.}

Your URL probably has ampersands in it. I had this problem, too, and I realized that my URL was full of ampersands (from CGI variables being passed) and so everything was getting sent to background in a weird way and thus not redirecting properly. If you put quotes around the URL it will fix it.

You have a scope problem indeed, because statement is a local method variable defined here:

protected void createContents() {
    ...
    Statement statement = null; // local variable
    ...
     btnInsert.addMouseListener(new MouseAdapter() { // anonymous inner class
        @Override
        public void mouseDown(MouseEvent e) {
            ...
            try {
                statement.executeUpdate(query); // local variable out of scope here
            } catch (SQLException e1) {
                e1.printStackTrace();
            }
            ...
    });
}

When you try to access this variable inside mouseDown() method you are trying to access a local variable from within an anonymous inner class and the scope is not enough. So it definitely must be final (which given your code is not possible) or declared as a class member so the inner class can access this statement variable.

Sources:

• Anonymous Classes
• How are Anonymous (inner) classes used in Java?

How to solve it?

You could...

Make statement a class member instead of a local variable:

public class A1 { // Note Java Code Convention, also class name should be meaningful   
    private Statement statement;
    ...
}

You could...

Define another final variable and use this one instead, as suggested by @HotLicks:

protected void createContents() {
    ...
    Statement statement = null;
    try {
        statement = connect.createStatement();
        final Statement innerStatement = statement;
    } catch (SQLException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    ...
}

But you should...

Reconsider your approach. If statement variable won't be used until btnInsert button is pressed then it doesn't make sense to create a connection before this actually happens. You could use all local variables like this:

btnInsert.addMouseListener(new MouseAdapter() {
   @Override
   public void mouseDown(MouseEvent e) {
       try {
           Class.forName("com.mysql.jdbc.Driver");
           try (Connection connect = DriverManager.getConnection(...);
                Statement statement = connect.createStatement()) {

                // execute the statement here

           } catch (SQLException ex) {
               ex.printStackTrace();
           }

       } catch (ClassNotFoundException ex) {
           e.printStackTrace();
       }
});

If, like me, you don't have access to the puppet master and need to print debug logs to inspect variables on your puppet client machine, you can try writing to a file from your puppet code itself:

file { '/tmp/puppet_debug.log':
  content => inline_template('<%= @variable_x.to_s %>'),
}

Maybe you should try using react-native-hr something like this:

<Hr lineColor='#b3b3b3'/>

documentation: https://www.npmjs.com/package/react-native-hr

What about the css opacity attribute? 0 to 1 values.

But then you probably need to use a more explicit dom element than "font". For instance:

<html><body><span style=\"opacity: 0.5;\"><font color=\"black\" face=\"arial\" size=\"4\">THIS IS MY TEXT</font></span></body></html>

As an additional information I would of course suggest you use CSS declarations outside of your html elements, but as well try to use the font css style instead of the font html tag.

For cross browser css3 styles generator, have a look at http://css3please.com/

You need to make sure that the first numeral to the right of the decimal point is always displayed. In custom format strings, # means display the number if it exists, and 0 means always display something, with 0 as the placeholder.

So in your case you will need something like:

=Format(Fields!CUL1.Value, "#,##0.##")

This saying: display 2 DP if they exist, for the non-zero part always display the lowest part, and use , as the grouping separator.

This is how it looks on your data (I've added a large value as well for reference):

If you're not interested in separating thousands, millions, etc, just use #0.## as Paul-Jan suggested.

The standard docs for Custom Numeric Format Strings are your best reference here.

I had the same error in Chrome. The Chrome console told me that the error was in the 1st line of the HTML file.

It was actually in the .js file. So watch out for setValidNou(1060, $(this).val(), 0') error types.

The following is a simplification/one liner from the accepted answer:

a = [2,3,4,5,6,7,8,9,0]
xyz = [0,12,4,6,242,7,9]

for x in (x for x in xyz if x not in a):
    print(x)

12
242

Notice that the generator was kept inline. This was tested on python2.7 and python3.6 (notice the parens in the print ;) )

For anyone going through this error and you've tried updating versions and making sure effects core is present etc and still scratching your head. Check the documentation for animate() and other syntax.

All I did was write "Linear" instead of "linear" and got the [this.easing] is not a function

$("#main").animate({ scrollLeft: '187px'}, 'slow', 'Linear'); //bad

$("#main").animate({ scrollLeft: '187px'}, 'slow', 'linear'); //good

If you use windows authentication, and you don't know a password to login as a user via username and password, you can do this: on the login-screen on SSMS click options at the bottom right, then go to the connection properties tab. Then you can type in manually the name of another database you have access to, over where it says , which will let you connect. Then follow the other advice for changing your default database

https://gyazo.com/c3d04c600311c08cb685bb668b569a67

This will do:

▢

It is ?
(known as a "WHITE SQUARE WITH ROUNDED CORNERS" on fileformat.info)

Or

◻

as ?
(known as a "WHITE MEDIUM SQUARE" on the same website)

Two with shadow:

❏
❑

as ? and ? . The difference between them is the shadows' shape. You can see it if you zoom in or if you print it out. (They are known as "LOWER RIGHT DROP-SHADOWED WHITE SQUARE" and "LOWER RIGHT SHADOWED WHITE SQUARE", respectively).

You can also use

☐

which is ?
(known as a "BALLOT BOX").

A sample is at http://jsfiddle.net/S2QCt/267/

(a note: on the Mac, ▢ is quite nice, because it is bigger and somewhat more elegant than ☐ On Windows, ☐ looks more standard, while ▢ is somewhat small.)

I accomplished it this way, as an example from my Redux reducer:

 const clone = { ...state };
 delete clone[action.id];
 return clone;

In other words:

const clone = { ...originalObject } // note: original object is not altered
delete clone[unwantedKey]           // or use clone.unwantedKey or any other applicable syntax
return clone                        // the original object without the unwanted key

Even though du usually prints disk usage and not actual data size, GNU coreutils du can print file's "apparent size" in bytes:

du -b FILE

But it won't work under BSD, Solaris, macOS, ...

Anaconda does not use the PYTHONPATH. One should however note that if the PYTHONPATH is set it could be used to load a library that is not in the anaconda environment. That is why before activating an environment it might be good to do a

unset PYTHONPATH

For instance this PYTHONPATH points to an incorrect pandas lib:

export PYTHONPATH=/home/john/share/usr/anaconda/lib/python
source activate anaconda-2.7
python
>>>> import pandas as pd
/home/john/share/usr/lib/python/pandas-0.12.0-py2.7-linux-x86_64.egg/pandas/hashtable.so: undefined symbol: PyUnicodeUCS2_DecodeUTF8
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/john/share/usr/lib/python/pandas-0.12.0-py2.7-linux-x86_64.egg/pandas/__init__.py", line 6, in <module>
    from . import hashtable, tslib, lib
ImportError: /home/john/share/usr/lib/python/pandas-0.12.0-py2.7-linux-x86_64.egg/pandas/hashtable.so: undefined symbol: PyUnicodeUCS2_DecodeUTF8

unsetting the PYTHONPATH prevents the wrong pandas lib from being loaded:

unset PYTHONPATH
source activate anaconda-2.7
python
>>>> import pandas as pd
>>>>

When you want to direct download any image or pdf file from browser instead on opening it in new tab then in javascript you should set value to download attribute of create dynamic link

    var path= "your file path will be here"; 
    var save = document.createElement('a');  
    save.href = filePath; 
    save.download = "Your file name here"; 
    save.target = '_blank'; 
    var event = document.createEvent('Event');
    event.initEvent('click', true, true); 
    save.dispatchEvent(event);
   (window.URL || window.webkitURL).revokeObjectURL(save.href);

For new Chrome update some time event is not working. for that following code will be use

  var path= "your file path will be here"; 
    var save = document.createElement('a');  
    save.href = filePath; 
    save.download = "Your file name here"; 
    save.target = '_blank'; 
    document.body.appendChild(save);
    save.click();
    document.body.removeChild(save);

Appending child and removing child is useful for Firefox, Internet explorer browser only. On chrome it will work without appending and removing child

we can use update for both insert and update/delte

Thanks for @bkurzius's answer and this update is for Charles 3.10+. (The reason is here)

1. Open Charles
2. Go to Proxy > SSL Proxy Settings...
3. Check “Enable SSL Proxying”
4. Select “Add location” and enter the host name and port (if needed)
5. Click ok and make sure the option is checked
6. Go to Help > SSL Proxying > Install Charles Root Certificate on a Mobile Device or Remote Browser..., and just follow the instruction. (use the Android's browser to download and install the certificate.)
7. In “Name the certificate” enter whatever you want
8. Click OK and you should get a message that the certificate was installed

DECLARE @i AS FLOAT = 2 SELECT @i / 3 SELECT cast(@i / cast(3 AS DECIMAL(18,2))as decimal (18,2))

Both factor and result requires casting to be considered as decimals.

This worked for me: Open task manager (of your OS) and kill adb.exe process. Now start adb again, now adb should start normally.

There is a Swift 3 solution from the checked solution :

self.perform(#selector(self.targetMethod), with: self, afterDelay: 1.0)

And there is the method

@objc fileprivate func targetMethod(){

}

A note of personal experience in addition to both Stefan Gehrig's answer and Dave None's answer (and mmmshuddup's reply):

I was having validation problems using both \n and PHP_EOL when I used the ICS validator at http://severinghaus.org/projects/icv/

I learned I had to use \r\n in order to get it to validate properly, so this was my solution:

function dateToCal($timestamp) {
  return date('Ymd\Tgis\Z', $timestamp);
}

function escapeString($string) {
  return preg_replace('/([\,;])/','\\\$1', $string);
}    

    $eol = "\r\n";
    $load = "BEGIN:VCALENDAR" . $eol .
    "VERSION:2.0" . $eol .
    "PRODID:-//project/author//NONSGML v1.0//EN" . $eol .
    "CALSCALE:GREGORIAN" . $eol .
    "BEGIN:VEVENT" . $eol .
    "DTEND:" . dateToCal($end) . $eol .
    "UID:" . $id . $eol .
    "DTSTAMP:" . dateToCal(time()) . $eol .
    "DESCRIPTION:" . htmlspecialchars($title) . $eol .
    "URL;VALUE=URI:" . htmlspecialchars($url) . $eol .
    "SUMMARY:" . htmlspecialchars($description) . $eol .
    "DTSTART:" . dateToCal($start) . $eol .
    "END:VEVENT" . $eol .
    "END:VCALENDAR";

    $filename="Event-".$id;

    // Set the headers
    header('Content-type: text/calendar; charset=utf-8');
    header('Content-Disposition: attachment; filename=' . $filename);

    // Dump load
    echo $load;

That stopped my parse errors and made my ICS files validate properly.

You dont need any external command if you have bash v4+

< file.txt mapfile -n1 && echo ${MAPFILE[0]}

or if you really want cat

cat file.txt | mapfile -n1 && echo ${MAPFILE[0]}

:)

from collections import Counter
a=["E","D","C","G","B","A","B","F","D","D","C","A","G","A","C","B","F","C","B"]

counter=Counter(a)

kk=[list(counter.keys()),list(counter.values())]

pd.DataFrame(np.array(kk).T, columns=['Letter','Count'])

Magic commands such as

%matplotlib qt  

work in the iPython console and Notebook, but do not work within a script.

In that case, after importing:

from IPython import get_ipython

use:

get_ipython().run_line_magic('matplotlib', 'inline')

for inline plotting of the following code, and

get_ipython().run_line_magic('matplotlib', 'qt')

for plotting in an external window.

Edit: solution above does not always work, depending on your OS/Spyder version Anaconda issue on GitHub. Setting the Graphics Backend to Automatic (as indicated in another answer: Tools >> Preferences >> IPython console >> Graphics --> Automatic) solves the problem for me.

Then, after a Console restart, one can switch between Inline and External plot windows using the get_ipython() command, without having to restart the console.

Updated for Apache 2.4, for non-systemd (e.g., CentOS 6.x, Amazon Linux AMI) and for systemd (e.g., CentOS 7.x):

There are two ways of having the apache process reload the configuration, depending on what you want done with its current threads, either advise to exit when idle, or killing them directly.

Note that Apache recommends using apachectl -k as the command, and for systemd, the command is replaced by httpd -k

apachectl -k graceful or httpd -k graceful

Apache will advise its threads to exit when idle, and then apache reloads the configuration (it doesn't exit itself), this means statistics are not reset.

apachectl -k restart or httpd -k restart

This is similar to stop, in that the process kills off its threads, but then the process reloads the configuration file, rather than killing itself.

Use git log to find the revision you want to rollback to, and take note of the commit hash. After that, you have 2 options:

1. If you plan to commit anything after that revision, I recommend you to checkout to a new branch: git checkout -b <new_branch_name> <hash>

2. If you don't plan to commit anything after that revision, you can simply checkout without a branch: git checkout <hash> - NOTE: This will put your repository in a 'detached HEAD' state, which means its currently not attached to any branch - then you'll have some extra work to merge new commits to an actual branch.

Example:

$ git log
commit 89915b4cc0810a9c9e67b3706a2850c58120cf75
Author: Jardel Weyrich <suppressed>
Date:   Wed Aug 18 20:15:01 2010 -0300

    Added a custom extension.

commit 4553c1466c437bdd0b4e7bb35ed238cb5b39d7e7
Author: Jardel Weyrich <suppressed>
Date:   Wed Aug 18 20:13:48 2010 -0300

    Missing constness.

$ git checkout 4553c1466c437bdd0b4e7bb35ed238cb5b39d7e7
Note: moving to '4553c1466c437bdd0b4e7bb35ed238cb5b39d7e7'
which isn't a local branch
If you want to create a new branch from this checkout, you may do so
(now or later) by using -b with the checkout command again. Example:
  git checkout -b <new_branch_name>
HEAD is now at 4553c14... Missing constness.

That way you don't lose any informations, thus you can move to a newer revision when it becomes stable.

Check this answer. Here your number start with "91**********".

Intent sendIntent = new Intent("android.intent.action.MAIN");

1. Right click on Drawable
2. Select New ---> Directory
3. Enter the directory name. Eg: logo.png(the location will already show the drawable folder by default)
4. Copy and paste the images directly into the drawable folder. While pasting you get an option to choose mdpi/xhdpi/xxhdpi etc for each of the images from a list. Select the appropriate option and enter the name of the image. Make sure to keep the same name as the directory name i.e logo.png
5. Do the same for the remaining images. All of them will be placed under the logo.png main folder.

I came across this issue as well. What I did was force kill the app on my device, then I opened up another console and ran

react-native start

and then I opened the app again from my device and it started working again.

EDIT: If you are using an android device via USB and have unplugged it or your computer went to sleep, you may have to first run

adb reverse tcp:8081 tcp:8081

Don't forget about <element class="ahover"><span>Text</span></a> if you use a text element.

.ahover {
    display: block;
    /** text-indent: -999em; ** if u use only only img **/
    position: relative;
}
.ahover:after {
    content: "";
    height: 100%;
    left: 0;
    opacity: 0;
    position: absolute;
    top: 0;
    transition: all 0.5s ease 0s;
    width: 100%;
    z-index: 1;
}
.ahover:hover:after {
    opacity: 1;
}
.ahover span {
    display: block;
    position: relative;
    z-index: 2;
}

You can define some default values and it prevents the fields from being serialized.

    [XmlElement, DefaultValue("")]
    string data;

    [XmlArray, DefaultValue(null)]
    List<string> data;

Android Studio 1.2.2 has moved the setting into the General subfolder of Editor settings.

The best solution I've found is to leave Eclipse in normal bright mode, and use an OS level screen inverter.

On OS X you can do Command + Option + Ctrl + 8, inverts the whole screen.

On Linux with Compiz, it's even better, you can do Windows + N to darken windows selectively (or Windows + M to do the whole screen).

On Windows, the only decent solution I've found is powerstrip, but it's only free for one year... then it's like $30 or something...

Then you can invert the screen, adjust the syntax-level colours to your liking, and you're off to the races, with cool shades on.

Unfortunately all classes hidden-*-up and hidden-*-down were removed from Bootstrap (as of Bootstrap Version 4 Beta, in Version 4 Alpha and Version 3 these classes still existed).

Instead, new classes d-* should be used, as mentioned here: https://getbootstrap.com/docs/4.0/migration/#utilities

I found out that the new approach is less useful under some circumstances. The old approach was to HIDE elements while the new approach is to SHOW elements. Showing elements is not that easy with CSS since you need to know if the element is displayed as block, inline, inline-block, table etc.

You might want to restore the former "hidden-*" styles known from Bootstrap 3 with this CSS:

/*\
 * Restore Bootstrap 3 "hidden" utility classes.
\*/

/* Breakpoint XS */
@media (max-width: 575px)
{
    .hidden-xs-down, .hidden-sm-down, .hidden-md-down, .hidden-lg-down, .hidden-xl-down, 
    .hidden-xs-up, 
    .hidden-unless-sm, .hidden-unless-md, .hidden-unless-lg, .hidden-unless-xl
    {
        display: none !important;
    }

}

/* Breakpoint SM */
@media (min-width: 576px) and (max-width: 767px)
{
    .hidden-sm-down, .hidden-md-down, .hidden-lg-down, .hidden-xl-down, 
    .hidden-xs-up, .hidden-sm-up, 
    .hidden-unless-xs, .hidden-unless-md, .hidden-unless-lg, .hidden-unless-xl
    {
        display: none !important;
    } 
}

/* Breakpoint MD */
@media (min-width: 768px) and (max-width: 991px)
{
    .hidden-md-down, .hidden-lg-down, .hidden-xl-down, 
    .hidden-xs-up, .hidden-sm-up, .hidden-md-up, 
    .hidden-unless-xs, .hidden-unless-sm, .hidden-unless-lg, .hidden-unless-xl
    {
        display: none !important;
    } 
}

/* Breakpoint LG */
@media (min-width: 992px) and (max-width: 1199px)
{
    .hidden-lg-down, .hidden-xl-down, 
    .hidden-xs-up, .hidden-sm-up, .hidden-md-up, .hidden-lg-up, 
    .hidden-unless-xs, .hidden-unless-sm, .hidden-unless-md, .hidden-unless-xl
    {
        display: none !important;
    } 
}

/* Breakpoint XL */
@media (min-width: 1200px)
{
    .hidden-xl-down, 
    .hidden-xs-up, .hidden-sm-up, .hidden-md-up, .hidden-lg-up, .hidden-xl-up, 
    .hidden-unless-xs, .hidden-unless-sm, .hidden-unless-md, .hidden-unless-lg
    {
        display: none !important;
    }

The classes hidden-unless-* were not included in Bootstrap 3, but they are useful as well and should be self-explanatory.

Try this style instead, it modifies the template itself. In there you can change everything you need to transparent:

<Style TargetType="{x:Type TabItem}">
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type TabItem}">
        <Grid>
          <Border Name="Border" Margin="0,0,0,0" Background="Transparent"
                  BorderBrush="Black" BorderThickness="1,1,1,1" CornerRadius="5">
            <ContentPresenter x:Name="ContentSite" VerticalAlignment="Center"
                              HorizontalAlignment="Center"
                              ContentSource="Header" Margin="12,2,12,2"
                              RecognizesAccessKey="True">
              <ContentPresenter.LayoutTransform>
            <RotateTransform Angle="270" />
          </ContentPresenter.LayoutTransform>
        </ContentPresenter>
          </Border>
        </Grid>
        <ControlTemplate.Triggers>
          <Trigger Property="IsSelected" Value="True">
            <Setter Property="Panel.ZIndex" Value="100" />
            <Setter TargetName="Border" Property="Background" Value="Red" />
            <Setter TargetName="Border" Property="BorderThickness" Value="1,1,1,0" />
          </Trigger>
          <Trigger Property="IsEnabled" Value="False">
            <Setter TargetName="Border" Property="Background" Value="DarkRed" />
            <Setter TargetName="Border" Property="BorderBrush" Value="Black" />
            <Setter Property="Foreground" Value="DarkGray" />
          </Trigger>

That would just be:

 Console.WriteLine(Variables.name);

and it needs to be public also:

public class Variables
{
   public static string name = "";
}

    });]

Since this operator reduces comparisons to an integer expression, it provides the most general purpose way to sort ascending or descending based on multiple columns/attributes.

For example, if I have an array of objects I can do things like this:

# `sort!` modifies array in place, avoids duplicating if it's large...

# Sort by zip code, ascending
my_objects.sort! { |a, b| a.zip <=> b.zip }

# Sort by zip code, descending
my_objects.sort! { |a, b| b.zip <=> a.zip }
# ...same as...
my_objects.sort! { |a, b| -1 * (a.zip <=> b.zip) }

# Sort by last name, then first
my_objects.sort! { |a, b| 2 * (a.last <=> b.last) + (a.first <=> b.first) }

# Sort by zip, then age descending, then last name, then first
# [Notice powers of 2 make it work for > 2 columns.]
my_objects.sort! do |a, b|
      8 * (a.zip   <=> b.zip) +
     -4 * (a.age   <=> b.age) +
      2 * (a.last  <=> b.last) +
          (a.first <=> b.first)
end

This basic pattern can be generalized to sort by any number of columns, in any permutation of ascending/descending on each.

add this

owl.trigger('owl.play',6000);

First, I would check what i gets initialized to, to see if the elements returned by getElementsByName are what you think they are. Maybe split the problem by trying it with a hard-coded name like timetemp0, without the concatenation. You can also run the code through a browser debugger (FireBug, Chrome Dev Tools, IE Dev Tools).

Also, for your if-condition, this should suffice:

if (!timetemp[0].value) {
    // The value is empty.
}
else {
    // The value is not empty.
}

The empty string in Javascript is a falsey value, so the logical negation of that will get you into the if-block.

new SimpleDateFormat("EEE MMM dd kk:mm:ss ZZZ yyyy");

and

new SimpleDateFormat("EEE MMM dd kk:mm:ss Z yyyy");

still runs. However, if your code throws an exception it is because your tool or jdk or any other reason. Because I got same error in my IDE but please check these http://ideone.com/Y2cRr (online ide) with ZZZ and with Z

RemoteSigned: all scripts you created yourself will be run, and all scripts downloaded from the Internet will need to be signed by a trusted publisher.

OK, change the policy by simply typing:

Set-ExecutionPolicy RemoteSigned

The (un)safe way to do this - if you are ok with not using option explicit - is...

Not TypeName(myObj) = "Empty"

This also handles the case if the object has not been declared. This is useful if you want to just comment out a declaration to switch off some behaviour...

Dim myObj as Object
Not TypeName(myObj) = "Empty"  '/ true, the object exists - TypeName is Object

'Dim myObj as Object
Not TypeName(myObj) = "Empty"  '/ false, the object has not been declared

This works because VBA will auto-instantiate an undeclared variable as an Empty Variant type. It eliminates the need for an auxiliary Boolean to manage the behaviour.

The easiest way in my experiences is to just use Dumpvalue.

use Dumpvalue;
...
my %hash = { key => "value", foo => "bar" };
my $dumper = new DumpValue();
$dumper->dumpValue(\%hash);

Works like a charm and you don't have to worry about formatting the hash, as it outputs it like the Perl debugger does (great for debugging). Plus, Dumpvalue is included with the stock set of Perl modules, so you don't have to mess with CPAN if you're behind some kind of draconian proxy (like I am at work).

Just to add to Alex Poole's answer, here is how you do the date and time:

    TO_DATE('31/DEC/2017 12:59:59', 'dd/mm/yyyy hh24:mi:ss')

Someone might find this useful, I had a problem flattening array at some dimension, I would call it last dimension so for example, if I have array like:

array (
  'germany' => 
  array (
    'cars' => 
    array (
      'bmw' => 
      array (
        0 => 'm4',
        1 => 'x3',
        2 => 'x8',
      ),
    ),
  ),
  'france' => 
  array (
    'cars' => 
    array (
      'peugeot' => 
      array (
        0 => '206',
        1 => '3008',
        2 => '5008',
      ),
    ),
  ),
)

Or:

array (
  'earth' => 
  array (
    'germany' => 
    array (
      'cars' => 
      array (
        'bmw' => 
        array (
          0 => 'm4',
          1 => 'x3',
          2 => 'x8',
        ),
      ),
    ),
  ),
  'mars' => 
  array (
    'france' => 
    array (
      'cars' => 
      array (
        'peugeot' => 
        array (
          0 => '206',
          1 => '3008',
          2 => '5008',
        ),
      ),
    ),
  ),
)

For both of these arrays when I call method below I get result:

array (
  0 => 
  array (
    0 => 'm4',
    1 => 'x3',
    2 => 'x8',
  ),
  1 => 
  array (
    0 => '206',
    1 => '3008',
    2 => '5008',
  ),
)

So I am flattening to last array dimension which should stay the same, method below could be refactored to actually stop at any kind of level:

function flattenAggregatedArray($aggregatedArray) {
    $final = $lvls = [];
    $counter = 1;
    $lvls[$counter] = $aggregatedArray;


    $elem = current($aggregatedArray);

    while ($elem){
        while(is_array($elem)){
            $counter++;
            $lvls[$counter] = $elem;
            $elem =  current($elem);
        }

        $final[] = $lvls[$counter];
        $elem = next($lvls[--$counter]);
        while ( $elem  == null){
            if (isset($lvls[$counter-1])){
                $elem = next($lvls[--$counter]);
            }
            else{
                return $final;
            }
        }
    }
}

Why the loop?

You could simply do this:

{% if 'priority' in data %}
    <p>Priority: {{ data['priority'] }}</p>
{% endif %}

When you were originally doing your string comparison, you should have used == instead.

Working in swift 3.0 For changing the title color you need to add titleTextAttributes like this

        let textAttributes = [NSForegroundColorAttributeName:UIColor.white]
        self.navigationController.navigationBar.titleTextAttributes = textAttributes

For changing navigationBar background color you can use this
        self.navigationController.navigationBar.barTintColor = UIColor.white

For changing navigationBar back title and back arrow color you can use this
       self.navigationController.navigationBar.tintColor = UIColor.white

I would choose this simple solution.

Summarizing it:

• Client "I want to login"
• Server generates a random number #S and sends it to the Client
• Client
  • reads username and password typed by the user
  • calculates the hash of the password, getting h(pw) (which is what is stored in the DB)
  • generates another random number #C
  • concatenates h(pw) + #S + #C and calculates its hash, call it h(all)
  • sends to the server username, #C and h(all)
• Server
  • retrieves h(pw)' for the specified username, from the DB
  • now it has all the elements to calculate h(all'), like Client did
  • if h(all) = h(all') then h(pw) = h(pw)', almost certainly

No one can repeat the request to log in as the specified user. #S adds a variable component to the hash, each time (it's fundamental). #C adds additional noise in it.

Follow the tutorial you listed above for setting up your key preferences in iterm2.

1. Create a new shorcut key
2. Choose "Send escape sequence" as the action
3. Then, to set cmd-left, in the text below that:
   • Enter [H for line start
     OR
   • Enter [F for line end

    ArrayTest obj=new ArrayTest(1);
    test.add(obj);
    ArrayTest obj1=new ArrayTest(2);
    test.add(obj1);
    ArrayTest obj2=new ArrayTest(3);
    test.add(obj2);

    test.remove(object of ArrayTest);

you can specify how you control each object.

Go figure?.....

Python has two kinds of sorts: a sort method (or "member function") and a sort function. The sort method operates on the contents of the object named -- think of it as an action that the object is taking to re-order itself. The sort function is an operation over the data represented by an object and returns a new object with the same contents in a sorted order.

Given a list of integers named l the list itself will be reordered if we call l.sort():

>>> l = [1, 5, 2341, 467, 213, 123]
>>> l.sort()
>>> l
[1, 5, 123, 213, 467, 2341]

This method has no return value. But what if we try to assign the result of l.sort()?

>>> l = [1, 5, 2341, 467, 213, 123]
>>> r = l.sort()
>>> print(r)
None

r now equals actually nothing. This is one of those weird, somewhat annoying details that a programmer is likely to forget about after a period of absence from Python (which is why I am writing this, so I don't forget again).

The function sorted(), on the other hand, will not do anything to the contents of l, but will return a new, sorted list with the same contents as l:

>>> l = [1, 5, 2341, 467, 213, 123]
>>> r = sorted(l)
>>> l
[1, 5, 2341, 467, 213, 123]
>>> r
[1, 5, 123, 213, 467, 2341]

Be aware that the returned value is not a deep copy, so be cautious about side-effecty operations over elements contained within the list as usual:

>>> spam = [8, 2, 4, 7]
>>> eggs = [3, 1, 4, 5]
>>> l = [spam, eggs]
>>> r = sorted(l)
>>> l
[[8, 2, 4, 7], [3, 1, 4, 5]]
>>> r
[[3, 1, 4, 5], [8, 2, 4, 7]]
>>> spam.sort()
>>> eggs.sort()
>>> l
[[2, 4, 7, 8], [1, 3, 4, 5]]
>>> r
[[1, 3, 4, 5], [2, 4, 7, 8]]

If both your client and service is installed on the same machine, and you are facing this problem with the correct (read: tried and tested elsewhere) client and service configurations, then this might be worth checking.

Check host entries in your host file

%windir%/system32/drivers/etc/hosts

Check to see if you are accessing your web service with a hostname, and that same hostname has been associated with an IP address in the hosts file mentioned above. If yes, NTLM/Windows credentials will NOT be passed from the client to the service as any request for that hostname will be routed again at the machine level.

Try either of the following

• Remove the host entry of that hostname from the hosts file
OR
• If removing host entry is not possible, then try accessing your service with another hostname. You might also try with IP address instead of hostname

Edit: Somehow the above situation is relevant on a load-balanced scenario. However, if removing the host entries is not possible, then disabling loop back check on the machine will help. Refer method 2 in the article https://support.microsoft.com/en-us/kb/896861

SUMMARY:

I provide here a no-jQuery cross-browser desktop-and-mobile ability to consistently respond to range/slider interactions, something not possible in current browsers. It essentially forces all browsers to emulate IE11's on("change"... event for either their on("change"... or on("input"... events. The new function is...

function onRangeChange(r,f) {
  var n,c,m;
  r.addEventListener("input",function(e){n=1;c=e.target.value;if(c!=m)f(e);m=c;});
  r.addEventListener("change",function(e){if(!n)f(e);});
}

...where r is your range input element and f is your listener. The listener will be called after any interaction that changes the range/slider value but not after interactions that do not change that value, including initial mouse or touch interactions at the current slider position or upon moving off either end of the slider.

Problem:

As of early June 2016, different browsers differ in terms of how they respond to range/slider usage. Five scenarios are relevant:

1. initial mouse-down (or touch-start) at the current slider position
2. initial mouse-down (or touch-start) at a new slider position
3. any subsequent mouse (or touch) movement after 1 or 2 along the slider
4. any subsequent mouse (or touch) movement after 1 or 2 past either end of the slider
5. final mouse-up (or touch-end)

The following table shows how at least three different desktop browsers differ in their behaviour with respect to which of the above scenarios they respond to:

Solution:

The onRangeChange function provides a consistent and predictable cross-browser response to range/slider interactions. It forces all browsers to behave according to the following table:

In IE11, the code essentially allows everything to operate as per the status quo, i.e. it allows the "change" event to function in its standard way and the "input" event is irrelevant as it never fires anyway. In other browsers, the "change" event is effectively silenced (to prevent extra and sometimes not-readily-apparent events from firing). In addition, the "input" event fires its listener only when the range/slider's value changes. For some browsers (e.g. Firefox) this occurs because the listener is effectively silenced in scenarios 1, 4 and 5 from the above list.

(If you truly require a listener to be activated in either scenario 1, 4 and/or 5 you could try incorporating "mousedown"/"touchstart", "mousemove"/"touchmove" and/or "mouseup"/"touchend" events. Such a solution is beyond the scope of this answer.)

Functionality in Mobile Browsers:

I have tested this code in desktop browsers but not in any mobile browsers. However, in another answer on this page MBourne has shown that my solution here "...appears to work in every browser I could find (Win desktop: IE, Chrome, Opera, FF; Android Chrome, Opera and FF, iOS Safari)". (Thanks MBourne.)

Usage:

To use this solution, include the onRangeChange function from the summary above (simplified/minified) or the demo code snippet below (functionally identical but more self-explanatory) in your own code. Invoke it as follows:

onRangeChange(myRangeInputElmt, myListener);

where myRangeInputElmt is your desired <input type="range"> DOM element and myListener is the listener/handler function you want invoked upon "change"-like events.

Your listener may be parameter-less if desired or may use the event parameter, i.e. either of the following would work, depending on your needs:

var myListener = function() {...

or

var myListener = function(evt) {...

(Removing the event listener from the input element (e.g. using removeEventListener) is not addressed in this answer.)

Demo Description:

In the code snippet below, the function onRangeChange provides the universal solution. The rest of the code is simply an example to demonstrate its use. Any variable that begins with my... is irrelevant to the universal solution and is only present for the sake of the demo.

The demo shows the range/slider value as well as the number of times the standard "change", "input" and custom "onRangeChange" events have fired (rows A, B and C respectively). When running this snippet in different browsers, note the following as you interact with the range/slider:

• In IE11, the values in rows A and C both change in scenarios 2 and 3 above while row B never changes.
• In Chrome and Safari, the values in rows B and C both change in scenarios 2 and 3 while row A changes only for scenario 5.
• In Firefox, the value in row A changes only for scenario 5, row B changes for all five scenarios, and row C changes only for scenarios 2 and 3.
• In all of the above browsers, the changes in row C (the proposed solution) are identical, i.e. only for scenarios 2 and 3.

Credit:

While the implementation here is largely my own, it was inspired by MBourne's answer. That other answer suggested that the "input" and "change" events could be merged and that the resulting code would work in both desktop and mobile browsers. However, the code in that answer results in hidden "extra" events being fired, which in and of itself is problematic, and the events fired differ between browsers, a further problem. My implementation here solves those problems.

I also prefer CSS over HTML; HTML is about content, CSS about presentation.

With CSS you have three options.

1. Inline CSS (like in Trevor's and Diodeus' solutions). Hard to maintain, and doesn't guarantee consistency: you'll have to check yourself that every image has the same border-width and border-color.
2. Internal stylesheet. Solves the consistency issue for all images on the page having class="hasBorder", but you'll have to include a stylesheet for each page, and again make sure "hasBorder" is defined the same each time.
3. External stylesheet. If you include a link to the external CSS file on each page all images with class="hasBorder" on all pages will have the same border.

Example using internal stylesheet:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
              "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Image with border</title>

  img.hasBorder { border:15px solid #66CC33; }
</style>

</head>

<body>
  <img class="hasBorder" src="peggy.jpg" alt="" />
</body>
</html>

If you want an external stylesheet, replace the <style>...</style> block with

<link rel="stylesheet" type="text/css" href="somestylesheet.css" />

For me following worked:

in directive declare it like this:

.directive('myDirective', function() {
    return {
        restrict: 'E',
        replace: true,
        scope: {
            myFunction: '=',
        },
        templateUrl: 'myDirective.html'
    };
})  

In directive template use it in following way:

<select ng-change="myFunction(selectedAmount)">

And then when you use the directive, pass the function like this:

<data-my-directive
    data-my-function="setSelectedAmount">
</data-my-directive>

You pass the function by its declaration and it is called from directive and parameters are populated.

selectedIndex is a JavaScript Select Property. For jQuery you can use this code:

jQuery(document).ready(function($) {
  $("#dropDownMenuKategorie").change(function() {
    // I personally prefer using console.log(), but if you want you can still go with the alert().
    console.log($(this).children('option:selected').index());
  });
});

It turns it into a bytes literal (or str in 2.x), and is valid for 2.6+.

The r prefix causes backslashes to be "uninterpreted" (not ignored, and the difference does matter).

Working with dates in javascript is always a bit of a hassle. I always end up using a library. Moment.js and XDate are both great:

http://momentjs.com/

http://arshaw.com/xdate/

Fiddle:

http://jsfiddle.net/39fWa/

var $output = $('#output'),
    tomorrow = moment().add('days', 1);

$('<pre />').appendTo($output).text(tomorrow);

tomorrow = new XDate().addDays(-1);

$('<pre />').appendTo($output).text(tomorrow);

?

To build on pinusnegra's answer, and in response to Gumbo's comment on that answer:

function has_leading_underscore($string) {

    return $string[0] === '_';

}

Running on PHP 5.3.0, the following works and returns the expected value, even without checking if the string is at least 1 character in length:

echo has_leading_underscore('_somestring').', ';
echo has_leading_underscore('somestring').', ';
echo has_leading_underscore('').', ';
echo has_leading_underscore(null).', ';
echo has_leading_underscore(false).', ';
echo has_leading_underscore(0).', ';
echo has_leading_underscore(array('_foo', 'bar'));

/*
 * output: true, false, false, false, false, false, false
 */

I don't know how other versions of PHP will react, but if they all work, then this method is probably more efficient than the substr route.

If you get an exception for : Invalid column type

Please use getNamedParameterJdbcTemplate() instead of getJdbcTemplate()

 List<Foo> foo = getNamedParameterJdbcTemplate().query("SELECT * FROM foo WHERE a IN (:ids)",parameters,
 getRowMapper());

Note that the second two arguments are swapped around.

Note: the answer below was written a long time prior to C# 6, which is planning to introduce the ability to declare parameterless constructors in structs - but they still won't be called in all situations (e.g. for array creation) (in the end this feature was not added to C# 6).

EDIT: I've edited the answer below due to Grauenwolf's insight into the CLR.

The CLR allows value types to have parameterless constructors, but C# doesn't. I believe this is because it would introduce an expectation that the constructor would be called when it wouldn't. For instance, consider this:

MyStruct[] foo = new MyStruct[1000];

The CLR is able to do this very efficiently just by allocating the appropriate memory and zeroing it all out. If it had to run the MyStruct constructor 1000 times, that would be a lot less efficient. (In fact, it doesn't - if you do have a parameterless constructor, it doesn't get run when you create an array, or when you have an uninitialized instance variable.)

The basic rule in C# is "the default value for any type can't rely on any initialization". Now they could have allowed parameterless constructors to be defined, but then not required that constructor to be executed in all cases - but that would have led to more confusion. (Or at least, so I believe the argument goes.)

EDIT: To use your example, what would you want to happen when someone did:

Rational[] fractions = new Rational[1000];

Should it run through your constructor 1000 times?

• If not, we end up with 1000 invalid rationals
• If it does, then we've potentially wasted a load of work if we're about to fill in the array with real values.

EDIT: (Answering a bit more of the question) The parameterless constructor isn't created by the compiler. Value types don't have to have constructors as far as the CLR is concerned - although it turns out it can if you write it in IL. When you write "new Guid()" in C# that emits different IL to what you get if you call a normal constructor. See this SO question for a bit more on that aspect.

I suspect that there aren't any value types in the framework with parameterless constructors. No doubt NDepend could tell me if I asked it nicely enough... The fact that C# prohibits it is a big enough hint for me to think it's probably a bad idea.

There is an another mature and actively developed "player" on the javascript linting front - ESLint:

ESLint is a tool for identifying and reporting on patterns found in ECMAScript/JavaScript code. In many ways, it is similar to JSLint and JSHint with a few exceptions:

• ESLint uses Esprima for JavaScript parsing.
• ESLint uses an AST to evaluate patterns in code.
• ESLint is completely pluggable, every single rule is a plugin and you can add more at runtime.

What really matters here is that it is extendable via custom plugins/rules. There are already multiple plugins written for different purposes. Among others, there are:

• eslint-plugin-angular (enforces some of the guidelines from John Papa's Angular Style Guide)
• eslint-plugin-jasmine
• eslint-plugin-backbone

And, of course, you can use your build tool of choice to run ESLint:

• grunt-eslint
• gulp-eslint

I had the exact same problem and figured out that by default the Mail Shield from Avast antivirus had the "Scan SSL connection" activated. Make sure to turn that off.

From my knowledge, Avast will "open" the mail, scan it for any viruses and then sign it using it's own certificate so the mail won't be signed by the gmail's certificate anymore which produces that error.

Solution 1:

• Turn off the SSL scans from your antivirus (or the entire mail shield).

Solution 2 (Should be the best security speaking):

• Get somehow the certificate used by the antivirus (Avast has an option to export it)
• Import it in your imap/pop/smtp client before connecting to gmail server.

From Wikipedia's Virtual function ...

In object-oriented programming, in languages such as C++, and Object Pascal, a virtual function or virtual method is an inheritable and overridable function or method for which dynamic dispatch is facilitated. This concept is an important part of the (runtime) polymorphism portion of object-oriented programming (OOP). In short, a virtual function defines a target function to be executed, but the target might not be known at compile time.

Unlike a non-virtual function, when a virtual function is overridden the most-derived version is used at all levels of the class hierarchy, rather than just the level at which it was created. Therefore if one method of the base class calls a virtual method, the version defined in the derived class will be used instead of the version defined in the base class.

This is in contrast to non-virtual functions, which can still be overridden in a derived class, but the "new" version will only be used by the derived class and below, but will not change the functionality of the base class at all.

whereas..

A pure virtual function or pure virtual method is a virtual function that is required to be implemented by a derived class if the derived class is not abstract.

When a pure virtual method exists, the class is "abstract" and can not be instantiated on its own. Instead, a derived class that implements the pure-virtual method(s) must be used. A pure-virtual isn't defined in the base-class at all, so a derived class must define it, or that derived class is also abstract, and can not be instantiated. Only a class that has no abstract methods can be instantiated.

A virtual provides a way to override the functionality of the base class, and a pure-virtual requires it.

You can simply do this in one line solution!

string s = "welcome to  london";
s.Replace(" ", "()").Replace(")(", "").Replace("()", " ");

You can choose other brackets (or even other characters) if you like.

To my knowledge the file has to be right in the folder where the 'this' class resides, i.e. not in WEB-INF/classes but nested even deeper (unless you write in a default package):

net/domain/pkg1/MyClass.java  
net/domain/pkg1/abc.txt

Putting the file in to your java sources should work, compiler copies that file together with class files.

Maybe you want str.istitle

>>> help(str.istitle)
Help on method_descriptor:

istitle(...)
    S.istitle() -> bool

    Return True if S is a titlecased string and there is at least one
    character in S, i.e. uppercase characters may only follow uncased
    characters and lowercase characters only cased ones. Return False
    otherwise.

>>> "Alpha_beta_Gamma".istitle()
False
>>> "Alpha_Beta_Gamma".istitle()
True
>>> "Alpha_Beta_GAmma".istitle()
False

Just remove/comment the following line from your httpd.conf file (etc/httpd/conf)

Require all granted

This is needed till Apache Version 2.2 and is not required from thereon.

I had a similar problem. Looked over the html several times and was sure it was correct. Then I started playing around with the order of jquery and bootstrap javascript.

Originally I had bootstrap.min.js loading BEFORE jquery.min.js. In this state, the menu would not expand when clicking on the menu icon.

Then I changed the order so that bootstrap.min.js came after jquery.min.js, and this solved the problem. I don't know enough about javascript to explain why this caused the problem (or fixed it), but that is what worked for me.

Additional info:

Both scripts are located at the bottom of the page, just before the tag. Both scripts are hosted on CDNs, not locally hosted.

If you're pretty sure your code is correct, give this a try.

+1 simple and cross-browser way: You can also put transparent picture over the video with css z-index and opacity. So users will see "save picture as" instead of "save video" in context menu.

unicodestring = '\xa0'

decoded_str = unicodestring.decode("windows-1252")
encoded_str = decoded_str.encode('ascii', 'ignore')

Works for me

JSON.stringify takes more optional arguments.

Try:

 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, 4); // Indented 4 spaces
 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, "\t"); // Indented with tab

From:

How can I beautify JSON programmatically?

Should work in modern browsers, and it is included in json2.js if you need a fallback for browsers that don't support the JSON helper functions. For display purposes, put the output in a <pre> tag to get newlines to show.

Use:

$filelist = @("11", "1", "2")
$filelist | sort @{expression={[int]$_}} | % {$newName = [string]([int]$_ + 1)}
New-Item $newName -ItemType Directory

In Eclipse, Goto Window-> Show View -> Other -> Android-> Logcat.

Logcat is nothing but a console of your Emulator or Device.

System.out.println does not work in Android. So you have to handle every thing in Logcat. More Info Look out this Documentation.

Edit 1: System.out.println is working on Logcat. If you use that the Tag will be like System.out and Message will be your message.

I have expanded the solution and combined it with another that I found to replace/update/remove the querystring parameters based on the users input and taking the urls anchor into consideration.

Not supplying a value will remove the parameter, supplying one will add/update the parameter. If no URL is supplied, it will be grabbed from window.location

function UpdateQueryString(key, value, url) {
    if (!url) url = window.location.href;
    var re = new RegExp("([?&])" + key + "=.*?(&|#|$)(.*)", "gi"),
        hash;

    if (re.test(url)) {
        if (typeof value !== 'undefined' && value !== null) {
            return url.replace(re, '$1' + key + "=" + value + '$2$3');
        } 
        else {
            hash = url.split('#');
            url = hash[0].replace(re, '$1$3').replace(/(&|\?)$/, '');
            if (typeof hash[1] !== 'undefined' && hash[1] !== null) {
                url += '#' + hash[1];
            }
            return url;
        }
    }
    else {
        if (typeof value !== 'undefined' && value !== null) {
            var separator = url.indexOf('?') !== -1 ? '&' : '?';
            hash = url.split('#');
            url = hash[0] + separator + key + '=' + value;
            if (typeof hash[1] !== 'undefined' && hash[1] !== null) {
                url += '#' + hash[1];
            }
            return url;
        }
        else {
            return url;
        }
    }
}

Update

There was a bug when removing the first parameter in the querystring, I have reworked the regex and test to include a fix.

Second Update

As suggested by @JarónBarends - Tweak value check to check against undefined and null to allow setting 0 values

Third Update

There was a bug where removing a querystring variable directly before a hashtag would lose the hashtag symbol which has been fixed

Fourth Update

Thanks @rooby for pointing out a regex optimization in the first RegExp object. Set initial regex to ([?&]) due to issue with using (\?|&) found by @YonatanKarni

Fifth Update

Removing declaring hash var in if/else statement

extends is for extending a class.

implements is for implementing an interface

The difference between an interface and a regular class is that in an interface you can not implement any of the declared methods. Only the class that "implements" the interface can implement the methods. The C++ equivalent of an interface would be an abstract class (not EXACTLY the same but pretty much).

Also java doesn't support multiple inheritance for classes. This is solved by using multiple interfaces.

 public interface ExampleInterface {
    public void doAction();
    public String doThis(int number);
 }

 public class sub implements ExampleInterface {
     public void doAction() {
       //specify what must happen
     }

     public String doThis(int number) {
       //specfiy what must happen
     }
 }

now extending a class

 public class SuperClass {
    public int getNb() {
         //specify what must happen
        return 1;
     }

     public int getNb2() {
         //specify what must happen
        return 2;
     }
 }

 public class SubClass extends SuperClass {
      //you can override the implementation
      @Override
      public int getNb2() {
        return 3;
     }
 }

in this case

  Subclass s = new SubClass();
  s.getNb(); //returns 1
  s.getNb2(); //returns 3

  SuperClass sup = new SuperClass();
  sup.getNb(); //returns 1
  sup.getNb2(); //returns 2

Also, note that an @Override tag is not required for implementing an interface, as there is nothing in the original interface methods to be overridden

I suggest you do some more research on dynamic binding, polymorphism and in general inheritance in Object-oriented programming

Using Proxies:

var a = new Proxy({ i: 0 }, {
    get: (target, name) => name === Symbol.toPrimitive ? () => ++target.i : target[name],
});
console.log(a == 1 && a == 2 && a == 3);

Proxies basically pretend to be a target object (the first parameter), but intercept operations on the target object (in this case the "get property" operation) so that there is an opportunity to do something other than the default object behavior. In this case the "get property" action is called on a when == coerces its type in order to compare it to each number. This happens:

1. We create a target object, { i: 0 }, where the i property is our counter
2. We create a Proxy for the target object and assign it to a
3. For each a == comparison, a's type is coerced to a primitive value
4. This type coercion results in calling a[Symbol.toPrimitive]() internally
5. The Proxy intercepts getting the a[Symbol.toPrimitive] function using the "get handler"
6. The Proxy's "get handler" checks that the property being gotten is Symbol.toPrimitive, in which case it increments and then returns the counter from the target object: ++target.i. If a different property is being retrieved, we just fall back to returning the default property value, target[name]

So:

var a = ...; // a.valueOf == target.i == 0
a == 1 && // a == ++target.i == 1
a == 2 && // a == ++target.i == 2
a == 3    // a == ++target.i == 3

As with most of the other answers, this only works with a loose equality check (==), because strict equality checks (===) do not do type coercion that the Proxy can intercept.

You could use Visual Studio Immediate Window

Just paste this (change actual to your object name obviously):

Newtonsoft.Json.JsonConvert.SerializeObject(actual);

It should print object in JSON

You should be able to copy it over textmechanic text tool or notepad++ and replace escaped quotes (\") with " and newlines (\r\n) with empty space, then remove double quotes (") from beginning and end and paste it to jsbeautifier to make it more readable.

UPDATE to OP's comment

public static class Dumper
{
    public static void Dump(this object obj)
    {
        Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(obj)); // your logger
    }
}

this should allow you to dump any object.

Hope this saves you some time.

It appears that you are using the default route which is defined as this:

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

The key part of that route is the {id} piece. If you look at your action method, your parameter is k instead of id. You need to change your action method to this so that it matches the route parameter:

// change int k to int id
public ActionResult DetailsData(int id)

If you wanted to leave your parameter as k, then you would change the URL to be:

http://localhost:7317/Employee/DetailsData?k=4

You also appear to have a problem with your connection string. In your web.config, you need to change your connection string to this (provided by haim770 in another answer that he deleted):

<connectionStrings>
  <add name="EmployeeContext"
       connectionString="Server=.;Database=mytry;integrated security=True;"
       providerName="System.Data.SqlClient" />
</connectionStrings>

There is another better reusable way as well:

Create a class:

class setDate implements OnFocusChangeListener, OnDateSetListener {   

       private EditText editText;
       private Calendar myCalendar;

       public setDate(EditText editText, Context ctx){
           this.editText = editText;
           this.editText.setOnFocusChangeListener(this);
           myCalendar = Calendar.getInstance();
       }

       @Override
       public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth)     {
           // this.editText.setText();

            String myFormat = "MMM dd, yyyy"; //In which you need put here
            SimpleDateFormat sdformat = new SimpleDateFormat(myFormat, Locale.US);
            myCalendar.set(Calendar.YEAR, year);
            myCalendar.set(Calendar.MONTH, monthOfYear);
            myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);

            editText.setText(sdformat.format(myCalendar.getTime()));

       }

        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            // TODO Auto-generated method stub
            if(hasFocus){
             new DatePickerDialog(ctx, this, myCalendar
                       .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                       myCalendar.get(Calendar.DAY_OF_MONTH)).show();
            }
        }

    }

Then call this class under onCreate function:

    EditText editTextFromDate = (EditText) findViewById(R.id.editTextFromDate);
    setDate fromDate = new setDate(editTextFromDate, this);

The easiest way is to not store the count, relying on the COUNT aggregate function to reflect the value as it is in the database:

   SELECT c.category_name,
          COUNT(p.post_id) AS num_posts
     FROM CATEGORY c
LEFT JOIN POSTS p ON p.category_id = c.category_id

You can create a view to house the query mentioned above, so you can query the view just like you would a table...

But if you're set on storing the number, use:

UPDATE CATEGORY
   SET count = count + 1
 WHERE category_id = ?

..replacing "?" with the appropriate value.

Using Math.Round():

int percentComplete = (int)Math.Round((double)(100 * complete) / total);

or manually rounding:

int percentComplete = (int)(0.5f + ((100f * complete) / total));

This is a bit confusing, but follow these steps to save the session.

1. Category -> Session -> enter public IP in Host and 22 in port.
2. Connection -> SSH -> Auth -> select the .ppk file
3. Category -> Session -> enter a name in Saved Session -> Click Save

To open the session, double click on particular saved session.

.NET Core is an open source and cross platform version of .NET. Microsoft products, besides the great abilities that they have, were always expensive for usual users, especially end users of products that has been made by .NET technologies.

Most of the low-level customers prefer to use Linux as their OS and before .NET Core they would not like to use Microsoft technologies, despite the great abilities of them. But after .NET Core production, this problem is solved completely and we can satisfy our customers without considering their OS, etc.

you should change cr_date(str) to datetime object then you 'll change the date to the specific format:

cr_date = '2013-10-31 18:23:29.000227'
cr_date = datetime.datetime.strptime(cr_date, '%Y-%m-%d %H:%M:%S.%f')
cr_date = cr_date.strftime("%m/%d/%Y")

Usage

Outside forms

<app-checkbox [label]="'Example'" [isChecked]="true"></app-checkbox>

Inside forms

<app-checkbox [label]="'Type 0'" formControlName="Type1"></app-checkbox>

This is exactly what you need. See it in action here 8FydL/445

One way you do this is set a counter and if number exceeds the certain number return false. easy as this.

var mybutton_counter=0;
$("#mybutton").on('click', function(e){
    if (mybutton_counter>0){return false;} //you can set the number to any
    //your call
     mybutton_counter++; //incremental
});

make sure, if statement is on top of your call.

Python string parsing walkthrough

Split a string on space, get a list, show its type, print it out:

el@apollo:~/foo$ python
>>> mystring = "What does the fox say?"

>>> mylist = mystring.split(" ")

>>> print type(mylist)
<type 'list'>

>>> print mylist
['What', 'does', 'the', 'fox', 'say?']

If you have two delimiters next to each other, empty string is assumed:

el@apollo:~/foo$ python
>>> mystring = "its  so   fluffy   im gonna    DIE!!!"

>>> print mystring.split(" ")
['its', '', 'so', '', '', 'fluffy', '', '', 'im', 'gonna', '', '', '', 'DIE!!!']

Split a string on underscore and grab the 5th item in the list:

el@apollo:~/foo$ python
>>> mystring = "Time_to_fire_up_Kowalski's_Nuclear_reactor."

>>> mystring.split("_")[4]
"Kowalski's"

Collapse multiple spaces into one

el@apollo:~/foo$ python
>>> mystring = 'collapse    these       spaces'

>>> mycollapsedstring = ' '.join(mystring.split())

>>> print mycollapsedstring.split(' ')
['collapse', 'these', 'spaces']

When you pass no parameter to Python's split method, the documentation states: "runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace".

Hold onto your hats boys, parse on a regular expression:

el@apollo:~/foo$ python
>>> mystring = 'zzzzzzabczzzzzzdefzzzzzzzzzghizzzzzzzzzzzz'
>>> import re
>>> mylist = re.split("[a-m]+", mystring)
>>> print mylist
['zzzzzz', 'zzzzzz', 'zzzzzzzzz', 'zzzzzzzzzzzz']

The regular expression "[a-m]+" means the lowercase letters a through m that occur one or more times are matched as a delimiter. re is a library to be imported.

Or if you want to chomp the items one at a time:

el@apollo:~/foo$ python
>>> mystring = "theres coffee in that nebula"

>>> mytuple = mystring.partition(" ")

>>> print type(mytuple)
<type 'tuple'>

>>> print mytuple
('theres', ' ', 'coffee in that nebula')

>>> print mytuple[0]
theres

>>> print mytuple[2]
coffee in that nebula

An easy way to pull of the p-values is to use statsmodels regression:

import statsmodels.api as sm
mod = sm.OLS(Y,X)
fii = mod.fit()
p_values = fii.summary2().tables[1]['P>|t|']

You get a series of p-values that you can manipulate (for example choose the order you want to keep by evaluating each p-value):

This

var verificaHorario = $("#tbIntervalos").find("#" + horaInicial);

will find you the td that needs to be blocked.

Actually this will also do:

var verificaHorario = $("#" + horaInicial);

Testing for the size() of the wrapped set will answer your question regarding the existence of the id.

You want the non-locale-aware floatval function:

float floatval ( mixed $var ) - Gets the float value of a string.

Example:

$string = '122.34343The';
$float  = floatval($string);
echo $float; // 122.34343

As explained in Nawaz's answer, you cannot sort your map by itself as you need it, because std::map sorts its elements based on the keys only. So, you need a different container, but if you have to stick to your map, then you can still copy its content (temporarily) into another data structure.

I think, the best solution is to use a std::set storing flipped key-value pairs as presented in ks1322's answer. The std::set is sorted by default and the order of the pairs is exactly as you need it:

3) If lhs.first<rhs.first, returns true. Otherwise, if rhs.first<lhs.first, returns false. Otherwise, if lhs.second<rhs.second, returns true. Otherwise, returns false.

This way you don't need an additional sorting step and the resulting code is quite short:

std::map<std::string, int> m;  // Your original map.
m["realistically"] = 1;
m["really"]        = 8;
m["reason"]        = 4;
m["reasonable"]    = 3;
m["reasonably"]    = 1;
m["reassemble"]    = 1;
m["reassembled"]   = 1;
m["recognize"]     = 2;
m["record"]        = 92;
m["records"]       = 48;
m["recs"]          = 7;

std::set<std::pair<int, std::string>> s;  // The new (temporary) container.

for (auto const &kv : m)
    s.emplace(kv.second, kv.first);  // Flip the pairs.

for (auto const &vk : s)
    std::cout << std::setw(3) << vk.first << std::setw(15) << vk.second << std::endl;

Output:

  1  realistically
  1     reasonably
  1     reassemble
  1    reassembled
  2      recognize
  3     reasonable
  4         reason
  7           recs
  8         really
 48        records
 92         record

Code on Ideone

Note: Since C++17 you can use range-based for loops together with structured bindings for iterating over a map. As a result, the code for copying your map becomes even shorter and more readable:

for (auto const &[k, v] : m)
    s.emplace(v, k);  // Flip the pairs.

Interfaces cannot require instance variables to be defined -- only methods.

(Variables can be defined in interfaces, but they do not behave as might be expected: they are treated as final static.)

Happy coding.

Matthias' answer is mostly right but it's still not filling the entire screen as it has a small padding on each side (pointed out by @Holmes). In addition to his code, we could fix this by extending Theme.Dialog style and add some attributes like this.

<style name="MyDialog" parent="@android:style/Theme.Dialog">
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowNoTitle">true</item>
</style>

Then we simply declare Activity with theme set to MyDialog:

<activity
    android:name=".FooActivity"
    android:theme="@style/MyDialog" />

Adding to @romanb brilliant answer.

This adds a little overhead in migration, because you obviously cannot create a field with not null constraint and with no default value.

// this up() migration is autogenerated, please modify it to your needs
$this->abortIf($this->connection->getDatabasePlatform()->getName() != "postgresql");

//lets add property without not null contraint        
$this->addSql("ALTER TABLE tablename ADD property BOOLEAN");

//get the default value for property       
$object = new Object();
$defaultValue = $menuItem->getProperty() ? "true":"false";

$this->addSql("UPDATE tablename SET property = {$defaultValue}");

//not you can add constraint
$this->addSql("ALTER TABLE tablename ALTER property SET NOT NULL");

With this answer, I encourage you to think why do you need the default value in the database in the first place? And usually it is to allow creating objects with not null constraint.

To complement the two previous answers, Angular2 supports both query parameters and path variables within routing. In @RouteConfig definition, if you define parameters within a path, Angular2 handles them as path variables and as query parameters if not.

Let's take a sample:

@RouteConfig([
  { path: '/:id', component: DetailsComponent, name: 'Details'}
])

If you call the navigate method of the router like this:

this.router.navigate( [
  'Details', { id: 'companyId', param1: 'value1'
}]);

You will have the following address: /companyId?param1=value1. The way to get parameters is the same for both, query parameters and path variables. The difference between them is that path variables can be seen as mandatory parameters and query parameters as optional ones.

Hope it helps you, Thierry

UPDATE: After changes in router alpha.31 http query params no longer work (Matrix params #2774). Instead angular router uses so called Matrix URL notation.

Reference https://angular.io/docs/ts/latest/guide/router.html#!#optional-route-parameters:

The optional route parameters are not separated by "?" and "&" as they would be in the URL query string. They are separated by semicolons ";" This is matrix URL notation — something you may not have seen before.

Think of "BeforeClass" as a static initializer for your test case - use it for initializing static data - things that do not change across your test cases. You definitely want to be careful about static resources that are not thread safe.

Finally, use the "AfterClass" annotated method to clean up any setup you did in the "BeforeClass" annotated method (unless their self destruction is good enough).

"Before" & "After" are for unit test specific initialization. I typically use these methods to initialize / re-initialize the mocks of my dependencies. Obviously, this initialization is not specific to a unit test, but general to all unit tests.

I don’t think that’s a good idea. Even if you find an appropriate regular expression (maybe using Unicode character properties), this wouldn’t prevent users from entering pseudo-names like John Doe, Max Mustermann (there even is a person with that name), Abcde Fghijk or Ababa Bebebe.

In my experience, the fastest method is

UPDATE table_name SET field = REPLACE(field, 'foo', 'bar') WHERE field LIKE '%foo%';

The INSTR() way is the second-fastest and omitting the WHERE clause altogether is slowest, even if the column is not indexed.

In addition to your CORS issue, the server you are trying to access has HTTP basic authentication enabled. You can include credentials in your cross-domain request by specifying the credentials in the URL you pass to the XHR:

url = 'http://username:[email protected]/testpage'

In case someone is feverishly googling to solve the bouncing images carousel thing, this helped me:

.fusion-carousel .fusion-carousel-item img {
    width: auto;
    height: 146px;
    max-height: 146px;
    object-fit: contain;
}

There is a pretty good example on https://developers.google.com/maps/documentation/javascript/examples/geocoding-simple

To shorten it up a little:

geocoder = new google.maps.Geocoder();

function codeAddress() {

    //In this case it gets the address from an element on the page, but obviously you  could just pass it to the method instead
    var address = document.getElementById( 'address' ).value;

    geocoder.geocode( { 'address' : address }, function( results, status ) {
        if( status == google.maps.GeocoderStatus.OK ) {

            //In this case it creates a marker, but you can get the lat and lng from the location.LatLng
            map.setCenter( results[0].geometry.location );
            var marker = new google.maps.Marker( {
                map     : map,
                position: results[0].geometry.location
            } );
        } else {
            alert( 'Geocode was not successful for the following reason: ' + status );
        }
    } );
}

if you are using emulator to run your app for local server. mention the local ipas 10.0.2.2 and have to give Internet permission into your app :

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

How about this;

myImageView.image=UIImage(named: "image_1")

where image_1 is within the assets folder as image_1.png.

This worked for me since i'm using a switch case to display an image slide.

A very simple way:

import * as myFunctionContainer from 'whatever-lib';

const fooSpy = spyOn(myFunctionContainer, 'myFunc');

select purpose.pname,company.cname
from purpose
Inner Join company
on purpose.id=company.id
where pname='Fever' and cname='ABC' in (
  select mname
  from medication
  where mname like 'A%'
  order by mname
); 

table.setDefaultEditor(Object.class, null);

it is saved in your Documents and Settings\%user%\Local Settings\Application Data......etc search for a file called user.config there

the location may change however.

Use set_index with stack for MultiIndex Series, then for DataFrame add reset_index with rename:

df1 = (df.set_index(["location", "name"])
         .stack()
         .reset_index(name='Value')
         .rename(columns={'level_2':'Date'}))
print (df1)
  location  name        Date  Value
0        A  test    Jan-2010     12
1        A  test    Feb-2010     20
2        A  test  March-2010     30
3        B   foo    Jan-2010     18
4        B   foo    Feb-2010     20
5        B   foo  March-2010     25

You need to find the selected option:

$(this).find(':selected').data('id')

or

$(this).find(':selected').attr('data-id')

although the first method is preferred.

What I normally do, similar to answer one:

var response = await httpClient.GetAsync(completeURL); // http://192.168.0.1:915/api/Controller/Object

if (response.IsSuccessStatusCode == true)
    {
        string res = await response.Content.ReadAsStringAsync();
        var content = Json.Deserialize<Model>(res);

// do whatever you need with the JSON which is in 'content'
// ex: int id = content.Id;

        Navigate();
        return true;
    }
    else
    {
        await JSRuntime.Current.InvokeAsync<string>("alert", "Warning, the credentials you have entered are incorrect.");
        return false;
    }

Where 'model' is your C# model class.

The HTML5 spec says that the type attribute is purely advisory and explains in detail how browsers should act if it's omitted (too much to quote here). It doesn't explicitly say that an omitted type attribute is either valid or invalid, but you can safely omit it knowing that browsers will still react as you expect.

1. Bill Burke has written a (nice article about class scanning] and then he wrote Scannotation.

2. Hibernate has this already written:

   • org.hibernate.ejb.packaging.Scanner
   • org.hibernate.ejb.packaging.NativeScanner

3. CDI might solve this, but don't know - haven't investigated fully yet

.

@Inject Instance< MyClass> x;
...
x.iterator() 

Also for annotations:

abstract class MyAnnotationQualifier
extends AnnotationLiteral<Entity> implements Entity {}

Assume that you've defined do_something as a function, and you'd like to perform it N times. Maybe you can try the following:

todos = [do_something] * N  
for doit in todos:  
    doit()

In windows, specified protocol for application can be registered in Registry. In this msdn doc shows Registering an Application to a URI Scheme.

For example, an executable files 'alert.exe' is to be started. The following item can be registered.

HKEY_CLASSES_ROOT
   alert
      (Default) = "URL:Alert Protocol"
      URL Protocol = ""
      DefaultIcon
         (Default) = "alert.exe,1"
      shell
         open
            command
               (Default) = "C:\Program Files\Alert\alert.exe"

Then you can write a html to test

<head>
    <title>alter</title>
</head>

<body>
    <a href="alert:" >alert</a>
<body>

When you declare:

new Vue({
    el: '#app',
    data () {
      return {}
    }
)}

That is typically your root Vue instance that the rest of the application descends from. This hangs off the root element declared in an html document, for example:

<html>
  ...
  <body>
    <div id="app"></div>
  </body>
</html>

The other syntax is declaring a component which can be registered and reused later. For example, if you create a single file component like:

// my-component.js
export default {
    name: 'my-component',
    data () {
      return {}
    }
}

You can later import this and use it like:

// another-component.js
<template>
  <my-component></my-component>
</template>
<script>
  import myComponent from 'my-component'
  export default {
    components: {
      myComponent
    }
    data () {
      return {}
    }
    ...
  }
</script>

Also, be sure to declare your data properties as functions, otherwise they are not going to be reactive.

You have to add click event to an exist element. You can not add event to dom elements dynamic created. I you want to add event to them, you should bind event to an existed element using ".on".

$('p').on('click','selector_you_dynamic_created',function(){...});

.delegate should work,too.

Add this code to the beginning:

    Application.ScreenUpdating = False
     With ThisWorkbook
      Dim ws As Worksheet
       For Each ws In Worksheets: ws.Visible = True: Next ws
     End With

Add this code to the end:

    With ThisWorkbook
     Dim ws As Worksheet
      For Each ws In Worksheets: ws.Visible = False: Next ws
    End With
     Application.ScreenUpdating = True

Adjust Code at the end if you want more than the first sheet to be active and visible. Such as the following:

     Dim ws As Worksheet
      For Each ws In Worksheets
       If ws.Name = "_DataRecords" Then

         Else: ws.Visible = False
       End If
      Next ws

To ensure the new sheet is the one renamed, adjust your code similar to the following:

     Sheets(Me.cmbxSheetCopy.value).Copy After:=Sheets(Sheets.Count)
     Sheets(Me.cmbxSheetCopy.value & " (2)").Select
     Sheets(Me.cmbxSheetCopy.value & " (2)").Name = txtbxNewSheetName.value

This code is from my user form that allows me to copy a particular sheet (chosen from a dropdown box) with the formatting and formula's that I want to a new sheet and then rename new sheet with the user Input. Note that every time a sheet is copied it is automatically given the old sheet name with the designation of " (2)". Example "OldSheet" becomes "OldSheet (2)" after the copy and before the renaming. So you must select the Copied sheet with the programs naming before renaming.

Try

sed 'NUMq;d'  /etc/*release | awk {'print $1}'

where NUM is line number

ex. sed '1q;d'  /etc/*release | awk {'print $1}'

Ranking by stars or forks is not working. Each promoted or created by a famous company repository is popular at the beginning. Also it is possible to have a number of them which are in trend right now (publications, marketing, events). It doesn't mean that those repositories are useful/popular.

The gitmostwanted.com project (repo at github) analyses GH Archive data in order to highlight the most interesting repositories and exclude others. Just compare the results with mentioned resources.

You can simply use String.Join function, and as separator use string.Empty because it uses StringBuilder internally.

string result = string.Join(string.Empty, new []{0,1,2,3,0,1});

E.g.: If you use semicolon as separator, the result would be 0;1;2;3;0;1.

It actually works with null separator, and second parameter can be enumerable of any objects, like:

string result = string.Join(null, new object[]{0,1,2,3,0,"A",DateTime.Now});

This works for me on OSX.

The file /Applications/MAMP/bin/mamp/mamp.conf.json holds the MAMP configuration, look for the section:

{
  "name": "PHP",
  "version": "5.6.28, 7.0.20"
}

which lists the the php versions which will be displayed in the GUI, obviously you need to have downloaded the PHP version from the MAMP site first and placed it in /Applications/MAMP/bin/php for this to work.

It depends, if you are referring to unsigned long the formatting character is "%lu". If you're referring to signed long the formatting character is "%ld".

I ran into this challenge when building an app where I wanted a table hidden for certain users but not for others.

Initially I set it up as display:none but then display:inline-block for those users who I wanted to see it but I experienced the formatting issues you might expect (columns consolidating or generally messy).

The way I worked around it was to show the table first and then do "display:none" for those users who I didn't want to see it. This way, it formatted normally but then disappeared as needed.

Bit of a lateral solution but might help someone!

A small note about the efficiency of abovementioned methods:

 library(microbenchmark)

  microbenchmark(
    which("Feb" == month.abb)[[1]],
    which(month.abb %in% "Feb"))

  Unit: nanoseconds
   min     lq    mean median     uq  max neval
   891  979.0 1098.00   1031 1135.5 3693   100
   1052 1175.5 1339.74   1235 1390.0 7399  100

So, the best one is

    which("Feb" == month.abb)[[1]]

SELECT 
  column1,
  column2 
FROM
  table_name 
WHERE id IN 
  (SELECT 
    MAX(id) 
  FROM
    table_name 
  GROUP BY column1) 
ORDER BY column1 ;

Follow as in picture for removing that lint error and adding automatic fix by addin g--fix in package.json

After implementing the accepted answer I did run across an issue that when navigating views with Prism the TextBox would still not get focus. A minor change to the PropertyChanged handler resolved it

    private static void OnIsFocusedPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var uie = (UIElement)d;
        if ((bool)e.NewValue)
        {
            uie.Dispatcher.BeginInvoke(DispatcherPriority.Input, new Action(() =>
            {
                uie.Focus();
            }));
        }
    }

You can add new function to your jQuery library by adding these line on your own script file and you can easily use fadeSlideRight() and fadeSlideLeft().

Note: you can change width of animation as you like instance of 750px.

$.fn.fadeSlideRight = function(speed,fn) {
    return $(this).animate({
        'opacity' : 1,
        'width' : '750px'
    },speed || 400, function() {
        $.isFunction(fn) && fn.call(this);
    });
}

$.fn.fadeSlideLeft = function(speed,fn) {
    return $(this).animate({
        'opacity' : 0,
        'width' : '0px'
    },speed || 400,function() {
        $.isFunction(fn) && fn.call(this);
    });
}

Don't use SSL on port 465, it's been deprecated since 1998 and is only used by Microsoft products that didn't get the memo; use TLS on port 587 instead: So, the code below should work very well for you.

mail->IsSMTP(); // telling the class to use SMTP
$mail->Host       = "smtp.gmail.com"; // SMTP server

$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->SMTPSecure = "tls";                 // sets the prefix to the servier
$mail->Host       = "smtp.gmail.com";      // sets GMAIL as the SMTP server
$mail->Port       = 587;                   // set the SMTP port for the 

Like this:

str_replace(array(':', '\\', '/', '*'), ' ', $string);

Or, in modern PHP (anything from 5.4 onwards), the slighty less wordy:

str_replace([':', '\\', '/', '*'], ' ', $string);

When your network team does ssl-inspection by rewriting certificates, then using a http url instead of a https one, combined with setting this var worked for me.

git config --global http.proxy http://proxy:8081

There is part of the spec that sure sounds like this... right in the "flex layout algorithm" and "main sizing" sections:

Otherwise, starting from the first uncollected item, collect consecutive items one by one until the first time that the next collected item would not fit into the flex container’s inner main size, or until a forced break is encountered. If the very first uncollected item wouldn’t fit, collect just it into the line. A break is forced wherever the CSS2.1 page-break-before/page-break-after [CSS21] or the CSS3 break-before/break-after [CSS3-BREAK] properties specify a fragmentation break.

From http://www.w3.org/TR/css-flexbox-1/#main-sizing

It sure sounds like (aside from the fact that page-breaks ought to be for printing), when laying out a potentially multi-line flex layout (which I take from another portion of the spec is one without flex-wrap: nowrap) a page-break-after: always or break-after: always should cause a break, or wrap to the next line.

.flex-container {
  display: flex;
  flex-flow: row wrap;
}

.child {
  flex-grow: 1;
}

.child.break-here {
  page-break-after: always;
  break-after: always;
}

However, I have tried this and it hasn't been implemented that way in...

• Safari (up to 7)
• Chrome (up to 43 dev)
• Opera (up to 28 dev & 12.16)
• IE (up to 11)

It does work the way it sounds (to me, at least) like in:

• Firefox (28+)

Sample at http://codepen.io/morewry/pen/JoVmVj.

I didn't find any other requests in the bug tracker, so I reported it at https://code.google.com/p/chromium/issues/detail?id=473481.

But the topic took to the mailing list and, regardless of how it sounds, that's not what apparently they meant to imply, except I guess for pagination. So there's no way to wrap before or after a particular box in flex layout without nesting successive flex layouts inside flex children or fiddling with specific widths (e.g. flex-basis: 100%).

This is deeply annoying, of course, since working with the Firefox implementation confirms my suspicion that the functionality is incredibly useful. Aside from the improved vertical alignment, the lack obviates a good deal of the utility of flex layout in numerous scenarios. Having to add additional wrapping tags with nested flex layouts to control the point at which a row wraps increases the complexity of both the HTML and CSS and, sadly, frequently renders order useless. Similarly, forcing the width of an item to 100% reduces the "responsive" potential of the flex layout or requires a lot of highly specific queries or count selectors (e.g. the techniques that may accomplish the general result you need that are mentioned in the other answers).

At least floats had clear. Something may get added at some point or another for this, one hopes.

FileZilla does not have any command line arguments (nor any other way) that allow an automatic transfer.

Some references:

• FileZilla Client command-line arguments
• https://trac.filezilla-project.org/ticket/2317
• How do I send a file with FileZilla from the command line?

Though you can use any other client that allows automation.

You have not specified, what protocol you are using. FTP or SFTP? You will definitely be able to use WinSCP, as it supports all protocols that FileZilla does (and more).

Combine WinSCP scripting capabilities with Windows Scheduler:

• Automate file transfers to FTP server or SFTP server;
• Schedule file transfers to FTP/SFTP server

A typical WinSCP script for upload (with SFTP) looks like:

open sftp://user:[email protected]/ -hostkey="ssh-rsa 2048 xxxxxxxxxxx...="
put c:\mypdfs\*.pdf /home/user/
close

With FTP, just replace the sftp:// with the ftp:// and remove the -hostkey="..." switch.

Similarly for download: How to schedule an automatic FTP download on Windows?

WinSCP can even generate a script from an imported FileZilla session.

For details, see the guide to FileZilla automation.

(I'm the author of WinSCP)

Another option, if you are using SFTP, is the psftp.exe client from PuTTY suite.

I find that psql.exe is quite picky with the slash direction, at least on windows (which the above looks like).

Here's an example. In a cmd window:

C:\Program Files\PostgreSQL\9.2\bin>psql.exe -U postgres
psql (9.2.4)
Type "help" for help.

postgres=# \i c:\temp\try1.sql    
c:: Permission denied
postgres=# \i c:/temp/try1.sql
CREATE TABLE
postgres=#

You can see it fails when I use "normal" windows slashes in a \i call. However both slash styles work if you pass them as input params to psql.exe, for example:

C:\Program Files\PostgreSQL\9.2\bin>psql.exe -U postgres -f c:\TEMP\try1.sql
CREATE TABLE

C:\Program Files\PostgreSQL\9.2\bin>psql.exe -U postgres -f c:/TEMP/try1.sql
CREATE TABLE

C:\Program Files\PostgreSQL\9.2\bin>

Add this in /etc/nginx/conf.d/default.conf:

fastcgi_param PATH_TRANSLATED $document_root$fastcgi_script_name;

You can use fetch module to copy files from remote hosts to local, and lookup module to read the content of fetched files.

You haven't actually asked a question, but assuming you have one, this could be your answer...

Assuming all characters, except the "Special Characters" are allowed you can write

String regex = "^[^<>'\"/;`%]*$";

In general the best way is to Change the table collation. However I have an old application and are not really able to estimate the outcome whether this has side effects. Therefore I tried somehow to convert the string into some other format that solved the collation problem. What I found working is to do the string compare by converting the strings into a hexadecimal representation of it's characters. On the database this is done with HEX(column). For PHP you may use this function:

public static function strToHex($string)
{
    $hex = '';
    for ($i=0; $i<strlen($string); $i++){
        $ord = ord($string[$i]);
        $hexCode = dechex($ord);
        $hex .= substr('0'.$hexCode, -2);
    }
    return strToUpper($hex);
}

When doing the database query, your original UTF8 string must be converted first into an iso string (e.g. using utf8_decode() in PHP) before using it in the DB. Because of the collation type the database cannot have UTF8 characters inside so the comparism should work event though this changes the original string (converting UTF8 characters that are not existend in the ISO charset result in a ? or these are removed entirely). Just make sure that when you write data into the database, that you use the same UTF8 to ISO conversion.

When you initialize unsigned int a to -1; it means that you are storing the 2's complement of -1 into the memory of a.
Which is nothing but 0xffffffff or 4294967295.

Hence when you print it using %x or %u format specifier you get that output.

By specifying signedness of a variable to decide on the minimum and maximum limit of value that can be stored.

Like with unsigned int: the range is from 0 to 4,294,967,295 and int: the range is from -2,147,483,648 to 2,147,483,647

For more info on signedness refer this

Had the same problem tried above solutions but none worked. I had to go through my java code only to find that the main function could not be recognised since there was no space btw it and (String) ie initial code:

public static void main(String[]args){

working code.

public static void main (String[]args){

Hope I helped someone.

I just found in my case Kaspersky Internet Security 2019 Firewall was blocking net access for python. Disabling firewall working smoothly. Or adding a exception rules for python app and all file extension with *.py will also work.

An alternative solution is to disable the AOT compiler:

ng build --prod --aot false

Add the param declation at the top of ps1 file

test.ps1

param(
  # Our preferred encoding
  [parameter(Mandatory=$false)]
  [ValidateSet("UTF8","Unicode","UTF7","ASCII","UTF32","BigEndianUnicode")]
  [string]$Encoding = "UTF8"
)

write ("Encoding : {0}" -f $Encoding)

result

C:\temp> .\test.ps1 -Encoding ASCII
Encoding : ASCII

2, 4, 5, 6, 7, 8, 9, 10, 11 (TypeScript) with Angular CLI

OneTime Setup

• npm install -g @angular/cli
• ng new projectFolder creates a new application

Bundling Step

• ng build --prod (run in command line when directory is projectFolder)

  flag prod bundle for production (see the Angular documentation for the list of option included with the production flag).

• Compress using Brotli compression the resources using the following command

  for i in dist/*; do brotli $i; done

bundles are generated by default to projectFolder/dist(/$projectFolder for v6+)**

Output

Sizes with Angular 11.0.5 with CLI 11.0.5and option CSS without Angular routing

• dist/main-[es-version].[hash].js Your application bundled [ ES5 size: 136 KB for new Angular CLI application empty, 38 KB compressed].
• dist/polyfill-[es-version].[hash].bundle.js the polyfill dependencies (@angular, RxJS...) bundled [ ES5 size: 36 KB for new Angular CLI application empty, 11 KB compressed].
• dist/index.html entry point of your application.
• dist/runtime-[es-version].[hash].bundle.js webpack loader
• dist/style.[hash].bundle.css the style definitions
• dist/assets resources copied from the Angular CLI assets configuration

Deployment

You can get a preview of your application using the ng serve --prod command that starts a local HTTP server such that the application with production files is accessible using http://localhost:4200.

For a production usage, you have to deploy all the files from the dist folder in the HTTP server of your choice.
