In Java 8 you could use streams and Files.lines:

List<String> list = null;
try (Stream<String> lines = Files.lines(myPathToTheFile))) {
    list = lines.collect(Collectors.toList());
} catch (IOException e) {
    LOGGER.error("Failed to load file.", e);
}

Or as a function including loading the file from the file system:

private List<String> loadFile() {
    List<String> list = null;
    URI uri = null;

    try {
        uri = ClassLoader.getSystemResource("example.txt").toURI();
    } catch (URISyntaxException e) {
        LOGGER.error("Failed to load file.", e);
    }

    try (Stream<String> lines = Files.lines(Paths.get(uri))) {
        list = lines.collect(Collectors.toList());
    } catch (IOException e) {
        LOGGER.error("Failed to load file.", e);
    }
    return list;
}

I try with this, no modifications on the css.

Yes, the new limit is approximately 1 million rows.

You can use this extension method.

public static class StreamExtensions
{
    public static byte[] ToByteArray(this Stream stream)
    {
        var bytes = new List<byte>();

        int b;
        while ((b = stream.ReadByte()) != -1)
            bytes.Add((byte)b);

        return bytes.ToArray();
    }
}

SELECT CAST(12.0910239123 AS DECIMAL(15, 2))

I tried Ninh Pham's solution but it didn't work for me until I tweaked it - see below. Remove contentType and don't encode your json data

$.fn.postJSON = function(url, data) {
    return $.ajax({
            type: 'POST',
            url: url,
            data: data,
            dataType: 'json'
        });

To avoid undesired effects while pasting, there is an option that needs to be set:

set paste

A useful command to have in your .vimrc is set pastetoggle=<F10> or some other button, to easily toggle between paste and nopaste.

The syntax for REPLACE:

REPLACE (string_expression,string_pattern,string_replacement)

So that the SQL you need should be:

UPDATE [DataTable] SET [ColumnValue] = REPLACE([ColumnValue], 'domain2', 'domain1')

The XPath spec. defines the string value of an element as the concatenation (in document order) of all of its text-node descendents.

This explains the "strange results".

"Better" results can be obtained using the expressions below:

//*[text() = 'qwerty']

The above selects every element in the document that has at least one text-node child with value 'qwerty'.

//*[text() = 'qwerty' and not(text()[2])]

The above selects every element in the document that has only one text-node child and its value is: 'qwerty'.

I had a similar problem. I wished to colour a complex drawable background for a view based on a color (int) value. I succeeded by using the code:

ColorStateList csl = new ColorStateList(new int[][]{{}}, new int[]{color});
textView.setBackgroundTintList(csl);

Where color is an int value representing the colour required. This represents the simple xml ColorStateList:

<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:color="color here"/>
</selector>

Hope this helps.

Make the value a list, e.g.

a["abc"] = [1, 2, "bob"]

UPDATE:

There are a couple of ways to add values to key, and to create a list if one isn't already there. I'll show one such method in little steps.

key = "somekey"
a.setdefault(key, [])
a[key].append(1)

Results:

>>> a
{'somekey': [1]}

Next, try:

key = "somekey"
a.setdefault(key, [])
a[key].append(2)

Results:

>>> a
{'somekey': [1, 2]}

The magic of setdefault is that it initializes the value for that key if that key is not defined, otherwise it does nothing. Now, noting that setdefault returns the key you can combine these into a single line:

a.setdefault("somekey",[]).append("bob")

Results:

>>> a
{'somekey': [1, 2, 'bob']}

You should look at the dict methods, in particular the get() method, and do some experiments to get comfortable with this.

ensure_ascii=False really only defers the issue to the decoding stage:

>>> dict2 = {'LeafTemps': '\xff\xff\xff\xff',}
>>> json1 = json.dumps(dict2, ensure_ascii=False)
>>> print(json1)
{"LeafTemps": "????"}
>>> json.loads(json1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/json/__init__.py", line 328, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python2.7/json/decoder.py", line 365, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python2.7/json/decoder.py", line 381, in raw_decode
    obj, end = self.scan_once(s, idx)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xff in position 0: invalid start byte

Ultimately you can't store raw bytes in a JSON document, so you'll want to use some means of unambiguously encoding a sequence of arbitrary bytes as an ASCII string - such as base64.

>>> import json
>>> from base64 import b64encode, b64decode
>>> my_dict = {'LeafTemps': '\xff\xff\xff\xff',} 
>>> my_dict['LeafTemps'] = b64encode(my_dict['LeafTemps'])
>>> json.dumps(my_dict)
'{"LeafTemps": "/////w=="}'
>>> json.loads(json.dumps(my_dict))
{u'LeafTemps': u'/////w=='}
>>> new_dict = json.loads(json.dumps(my_dict))
>>> new_dict['LeafTemps'] = b64decode(new_dict['LeafTemps'])
>>> print new_dict
{u'LeafTemps': '\xff\xff\xff\xff'}

If you want to see a more detailed discussion of differences for the commands, see the Details about Differences section, below.

From the LeMoDa.net website¹ (archived), specifically the Windows and Unix command line equivalents page (archived), I found the following². There's a better/more complete table in the next edit.

Windows command     Unix command
rmdir               rmdir
rmdir /s            rm -r
move                mv

I'm interested to hear from @Dave and @javadba to hear how equivalent the commands are - how the "behavior and capabilities" compare, whether quite similar or "woefully NOT equivalent".

All I found out was that when I used it to try and recursively remove a directory and its constituent files and subdirectories, e.g.

(Windows cmd)>rmdir /s C:\my\dirwithsubdirs\

gave me a standard Windows-knows-better-than-you-do-are-you-sure message and prompt

dirwithsubdirs, Are you sure (Y/N)?

and that when I typed Y, the result was that my top directory and its constituent files and subdirectories went away.

Edit

I'm looking back at this after finding this answer. I retried each of the commands, and I'd change the table a little bit.

Windows command     Unix command
rmdir               rmdir
rmdir /s /q         rm -r
rmdir /s /q         rm -rf
rmdir /s            rm -ri
move                mv
del <file>          rm <file>

If you want the equivalent for

rm -rf

you can use

rmdir /s /q

or, as the author of the answer I sourced described,

But there is another "old school" way to do it that was used back in the day when commands did not have options to suppress confirmation messages. Simply ECHO the needed response and pipe the value into the command.

echo y | rmdir /s

Details about Differences

I tested each of the commands using Windows CMD and Cygwin (with its bash).

Before each test, I made the following setup.

Windows CMD

>mkdir this_directory
>echo some text stuff > this_directory/some.txt
>mkdir this_empty_directory

Cygwin bash

$ mkdir this_directory
$ echo "some text stuff" > this_directory/some.txt
$ mkdir this_empty_directory

That resulted in the following file structure for both.

base
|-- this_directory
|   `-- some.txt
`-- this_empty_directory

Here are the results. Note that I'll not mark each as CMD or bash; the CMD will have a > in front, and the bash will have a $ in front.

RMDIR

>rmdir this_directory
The directory is not empty.

>tree /a /f .
Folder PATH listing for volume Windows
Volume serial number is ¦¦¦¦¦¦¦¦ ¦¦¦¦:¦¦¦¦
base
+---this_directory
|       some.txt
|
\---this_empty_directory

> rmdir this_empty_directory

>tree /a /f .
base
\---this_directory
        some.txt

$ rmdir this_directory
rmdir: failed to remove 'this_directory': Directory not empty

$ tree --charset=ascii
base
|-- this_directory
|   `-- some.txt
`-- this_empty_directory

2 directories, 1 file

$ rmdir this_empty_directory

$ tree --charset=ascii
base
`-- this_directory
    `-- some.txt

RMDIR /S /Q and RM -R ; RM -RF

>rmdir /s /q this_directory

>tree /a /f
base
\---this_empty_directory

>rmdir /s /q this_empty_directory

>tree /a /f
base
No subfolders exist

$ rm -r this_directory

$ tree --charset=ascii
base
`-- this_empty_directory

$ rm -r this_empty_directory

$ tree --charset=ascii
base
0 directories, 0 files

$ rm -rf this_directory

$ tree --charset=ascii
base
`-- this_empty_directory

$ rm -rf this_empty_directory

$ tree --charset=ascii
base
0 directories, 0 files

RMDIR /S AND RM -RI Here, we have a bit of a difference, but they're pretty close.

>rmdir /s this_directory
this_directory, Are you sure (Y/N)? y

>tree /a /f
base
\---this_empty_directory

>rmdir /s this_empty_directory
this_empty_directory, Are you sure (Y/N)? y

>tree /a /f
base
No subfolders exist

$ rm -ri this_directory
rm: descend into directory 'this_directory'? y
rm: remove regular file 'this_directory/some.txt'? y
rm: remove directory 'this_directory'? y

$ tree --charset=ascii
base
`-- this_empty_directory

$ rm -ri this_empty_directory
rm: remove directory 'this_empty_directory'? y

$ tree --charset=ascii
base
0 directories, 0 files

I'M HOPING TO GET A MORE THOROUGH MOVE AND MV TEST

Notes

1. I know almost nothing about the LeMoDa website, other than the fact that the info is

and that there seem to be a bunch of useful programming tips along with some humour (yes, the British spelling) and information on how to fix Japanese toilets. I also found some stuff talking about the "Ibaraki Report", but I don't know if that is the website.

I think I shall go there more often; it's quite useful. Props to Ben Bullock, whose email is on his page. If he wants me to remove this info, I will.

2. Actually, I found the information with a Google search for "cmd equivalent of rm"

https://www.google.com/search?q=cmd+equivalent+of+rm

The information I'm sharing came up first.

I believe Python is the only widely used language that doesn't support \z in this way (yet). There are Python bindings for Russ Cox / Google's super fast re2 C++ library that can be "dropped in" as a replacement for the bundled re.

There's an excellent discussion (with workarounds) for this at Perl Compatible Regular Expression (PCRE) in Python, here on SO.

python
Python 2.7.11 (default, Jan 16 2016, 01:14:05) 
[GCC 4.2.1 Compatible FreeBSD Clang 3.4.1 on freebsd10
Type "help", "copyright", "credits" or "license" for more information.
>>> import re2 as re
>>> 
>>> re.match(r'\A\z', "")
<re2.Match object at 0x805d97170>

@tchrist's answer is worth the read.

A nice solution that I've found is to do on UI something like:

<div *ngIf="isDataLoaded">
 ...Your page...
</div

Only when: isDataLoaded is true the page is rendered.

import imp
imp.reload(script4)

Using the latest versions of Subclipse, you can actually view them without using the cmd prompt. On the file, simply right-click => Team => Switch to another branch/tag/revision. Besides the revision field, you click select, and you'll see all the versions of that file.

Avoid using Xcode to rename files in a folder reference. If you rename a file using Xcode, it will be marked for commit. If you later delete it before the commit, you will end up with this error.

Upgrade the pip via command prompt ( Python Directory )

D:\Python 3.7.2>python -m pip install --upgrade pip

Now you can install the required Module

D:\Python 3.7.2>python -m pip install <<yourModuleName>>

This helped in my case:

options: {
    responsive: true,
    scales: {
        yAxes: [{
            display: true,
            ticks: {
                min:0,
                max:100
            }
        }]
    }
}

//auth required or redirect
app.use('/account', function(req, res, next) {
  console.log(req.path);
  if ( !req.session.user ) {
    res.redirect('/login?ref='+req.path);
  } else {
    next();
  }
});

req.path is / when it should be /account ??

The reason for this is that Express subtracts the path your handler function is mounted on, which is '/account' in this case.

Why do they do this?

Because it makes it easier to reuse the handler function. You can make a handler function that does different things for req.path === '/' and req.path === '/goodbye' for example:

function sendGreeting(req, res, next) {
  res.send(req.path == '/goodbye' ? 'Farewell!' : 'Hello there!')
}

Then you can mount it to multiple endpoints:

app.use('/world', sendGreeting)
app.use('/aliens', sendGreeting)

Giving:

/world           ==>  Hello there!
/world/goodbye   ==>  Farewell!
/aliens          ==>  Hello there!
/aliens/goodbye  ==>  Farewell!

If you've opened a table and you want to clear an existing value to NULL, click on the value, and press Ctrl+0.

You don't need to use anything but plain React and ES6 to achieve what you want. As per Jim's answer, just define the constant in the right place. I like the idea of keeping the constant local to the component if not needed externally. The below is an example of possible usage.

import React from "react";

const sizeToLetterMap = {
  small_square: 's',
  large_square: 'q',
  thumbnail: 't',
  small_240: 'm',
  small_320: 'n',
  medium_640: 'z',
  medium_800: 'c',
  large_1024: 'b',
  large_1600: 'h',
  large_2048: 'k',
  original: 'o'
};

class PhotoComponent extends React.Component {
  constructor(args) {
    super(args);
  }

  photoUrl(image, size_text) {
    return (<span>
      Image: {image}, Size Letter: {sizeToLetterMap[size_text]}
    </span>);
  }

  render() {
    return (
      <div className="photo-wrapper">
        The url is: {this.photoUrl(this.props.image, this.props.size_text)}
      </div>
    )
  }
}

export default PhotoComponent;

// Call this with <PhotoComponent image="abc.png" size_text="thumbnail" />
// Of course the component must first be imported where used, example:
// import PhotoComponent from "./photo_component.jsx";

Use:

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

The option you should use is iDisplayLength:

$('#adminProducts').dataTable({
  'iDisplayLength': 100
});

$('#table').DataTable({
   "lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});

It will Load by default all entries.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

If you want to load by default 25 not all do this.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
});

Try or:

WHERE id = 3 or id = 4

Or the equivalent in:

WHERE id in (3,4)

If you want to refresh the page if there is no activity then you need to figure out how to define activity. Let's say we refresh the page every minute unless someone presses a key or moves the mouse. This uses jQuery for event binding:

<script>
     var time = new Date().getTime();
     $(document.body).bind("mousemove keypress", function(e) {
         time = new Date().getTime();
     });

     function refresh() {
         if(new Date().getTime() - time >= 60000) 
             window.location.reload(true);
         else

Here http://www.alteridem.net/2007/08/22/the-yield-statement-in-c/ is very good example:

public static IEnumerable<int> Range( int min, int max )
{
   while ( true )
   {
      if ( min >= max )
      {
         yield break;
      }
      yield return min++;
   }
}

and explanation, that if a yield break statement is hit within a method, execution of that method stops with no return. There are some time situations, when you don't want to give any result, then you can use yield break.

DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
formatter.setLenient(false);
try {
    Date date= formatter.parse("02/03/2010");
} catch (ParseException e) {
    //If input date is in different format or invalid.
}

formatter.setLenient(false) will enforce strict matching.

If you are using Joda-Time -

private boolean isValidDate(String dateOfBirth) {
        boolean valid = true;
        try {
            DateTimeFormatter formatter = DateTimeFormat.forPattern("dd/MM/yyyy");
            DateTime dob = formatter.parseDateTime(dateOfBirth);
        } catch (Exception e) {
            valid = false;
        }
        return valid;
    }

re install your java. First check your OS version.

If your Local branch and remote branch is the same name then you can just do it:

git push origin branchName

When your local and remote branch name is different then you can just do it:

git push origin localBranchName:remoteBranchName

If you want to delete all your local branches, here is the simple command:

git branch -D `git branch`

Note: This will delete all the branches except the current checked out branch

combining 3 answers together: (because a select statement does not execute the DDL)

set pagesize 0

alter session set skip_unusable_indexes = true;
spool c:\temp\disable_indexes.sql
select 'alter index ' || u.index_name || ' unusable;' from user_indexes u;
spool off
@c:\temp\disable_indexes.sql

Do import...

select 'alter index ' || u.index_name || 
' rebuild online;' from user_indexes u;

Note this assumes that the import is going to happen in the same (sqlplus) session.
If you are calling "imp" it will run in a separate session so you would need to use "ALTER SYSTEM" instead of "ALTER SESSION" (and remember to put the parameter back the way you found it.

An alternative would be to use Font-Awesome for icons:

Including Font-Awesome

Open Font-Awesome on CDNJS and copy the CSS url of the latest version:

<link rel="stylesheet" href="<url>">

Or in CSS

@import url("<url>");

For example (note, the version will change):

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.css">

Usage:

<i class="fa fa-bed"></i>

It contains a lot of icons!

\d{10}

I believe that should do it

ALTER TABLE Protocols
ADD ProtocolTypeID int NOT NULL DEFAULT(1)
GO

The inclusion of the DEFAULT fills the column in existing rows with the default value, so the NOT NULL constraint is not violated.

Basically, you check if an object is an instance of a specific class. You normally use it, when you have a reference or parameter to an object that is of a super class or interface type and need to know whether the actual object has some other type (normally more concrete).

Example:

public void doSomething(Number param) {
  if( param instanceof Double) {
    System.out.println("param is a Double");
  }
  else if( param instanceof Integer) {
    System.out.println("param is an Integer");
  }

  if( param instanceof Comparable) {
    //subclasses of Number like Double etc. implement Comparable
    //other subclasses might not -> you could pass Number instances that don't implement that interface
    System.out.println("param is comparable"); 
  }
}

Note that if you have to use that operator very often it is generally a hint that your design has some flaws. So in a well designed application you should have to use that operator as little as possible (of course there are exceptions to that general rule).

To the radio buttons works correctly, you must to have grouped by his name. (Ex. name="type")

 <fieldset>
    <legend>Please select one of the following</legend>
    <input type="radio" name="type" id="track" value="track" /><label for="track">Track Submission</label><br />
    <input type="radio" name="type" id="event" value="event"  /><label for="event">Events and Artist booking</label><br />
    <input type="radio" name="type" id="message" value="message" /><label for="message">Message us</label><br />

It will returns the value of the radio button checked (Ex. track | event | message)

It's simple. Just change the port. Use 3268 instead of 389. If your domain name DOMAIN.LOCAL, in search put DC=DOMAIN,DC=LOCAL

Port 3268: This port is used for queries that are specifically targeted for the global catalog. LDAP requests sent to port 3268 can be used to search objects in the entire forest. However, only the attributes marked for replication to the global catalog can be returned.

Port 389: This port is used for requesting information from the Domain Controller. LDAP requests sent to port 389 can be used to search objects only within the global catalog’s home domain. However, the application can possible to obtain all of the attributes searched objects.

As a result of this discussion https://github.com/CocoaPods/CocoaPods/issues/4989

Briefly: CocoaPods repository experiences a huge volume of fetches from GitHub and it was the problem. Changes have been available since version 1.0.0.beta.6.

Tips from this document:

If for whatever reason you cannot upgrade to version 1.0.0 just yet, you can perform the following steps to convert your clone of the Master spec-repo from a shallow to a full clone:

$ cd ~/.cocoapods/repos/master
$ git fetch --unshallow

My hack to first installation:

1. pod setup
2. Ctrl+C
After that I could find ~/.cocoapods/repos/ empty directory 
3. Download  https://github.com/CocoaPods/Specs/archive/master.zip
4. unpack it to ~/.cocoapods/repos/
5. Move to project folder
6. pod install --no-repo-update

    def reset_parameters(self):
        init.kaiming_uniform_(self.weight, a=math.sqrt(3))
        if self.bias is not None:
            fan_in, _ = init._calculate_fan_in_and_fan_out(self.weight)
            bound = 1 / math.sqrt(fan_in)
            init.uniform_(self.bias, -bound, bound)

But I wanna point out that actually we know some assumptions in the paper of Kaiming He, Delving Deep into Rectifiers: Surpassing Human-Level Performance on ImageNet Classification, are not appropriate, though it looks like the deliberately designed initialization method makes a hit in practice.

E.g., within the subsection of Backward Propagation Case, they assume that $w_l$ and $\delta y_l$ are independent of each other. But as we all known, take the score map $\delta y^L_i$ as an instance, it often is $y_i-softmax(y^L_i)=y_i-softmax(w^L_ix^L_i)$ if we use a typical cross entropy loss function objective.

So I think the true underlying reason why He's Initialization works well remains to unravel. Cuz everyone has witnessed its power on boosting deep learning training.

The snippet you're showing doesn't seem to be directly responsible for the error.

This is how you can CAUSE the error:

namespace MyNameSpace
{
   int i; <-- THIS NEEDS TO BE INSIDE THE CLASS

   class MyClass
   {
      ...
   }
}

If you don't immediately see what is "outside" the class, this may be due to misplaced or extra closing bracket(s) }.

The first argument is the file you wish to execute, and the second argument is an array of null-terminated strings that represent the appropriate arguments to the file as specified in the man page.

For example:

char *cmd = "ls";
char *argv[3];
argv[0] = "ls";
argv[1] = "-la";
argv[2] = NULL;

execvp(cmd, argv); //This will run "ls -la" as if it were a command

For that particular case you can use:

.detail_container > ul + h1{ 
    color: blue; 
}

But if you need that same selector on many cases, you should have a class for those, like BoltClock said.

This worked well for me, additionally using BASIC authentication:

curl -v --proxy '' --basic -u Administrator:password -X POST -H "Content-Type: application/json"
        --data-binary '{"value":"30","type":"Tip 3","targetModule":"Target 3","configurationGroup":null,"name":"Configuration Deneme 3","description":null,"identity":"Configuration Deneme 3","version":0,"systemId":3,"active":true}'
        http://httpbin.org/post

Of course, you should never use BASIC authentication without SSL and a checked certificate.

I ran into this again today, using Cygwin's cURL 7.49.1 for Windows... And when using --data or --data-binary with a JSON argument, cURL got confused and would interpret the {} in the JSON as a URL template. Adding a -g argument to turn off cURL globbing fixed that.

See also Passing a URL with brackets to curl.

If you are set on using EXISTS you can use the below in SQL Server:

SELECT * FROM TableB as b
WHERE NOT EXISTS
(
   SELECT * FROM TableA as a
   WHERE b.id = a.id
)

You can write the php code in another file and include it in the proper place where you want it.

AJAX is also used to display HTML content that is formed by PHP into a specified HTML tag.

Using jQuery:

$.ajax({url: "test.php"}).done(function( html ) {
    $("#results").append(html);
});

Above code will execute test.php and result will be displayed in the element with id results.

I would suggest using --limit <hostname or ip>

You have to run 'bibtex':

You may need to set up a root account for your MySQL database:

In the terminal type:

mysqladmin -u root password 'root password goes here'

And then to invoke the MySQL client:

mysql -h localhost -u root -p

Simplified way of doing this based on the accepted answer.

In my case I needed to check if current date (Today) is pithing the range of two other dates so used newDate() instead of hardcoded values but you can get the point how you can use hardcoded dates.

var currentDate = new Date().toJSON().slice(0,10);
var from = new Date('2020/01/01');
var to   = new Date('2020/01/31');
var check = new Date(currentDate);

console.log(check > from && check < to);

Normalizing your operational tables as suggested by Transact Charlie, is a good idea, and will save many headaches and problems over time - but there are such things as interface tables, which support integration with external systems, and reporting tables, which support things like analytical processing; and those types of tables should not necessarily be normalized - in fact, very often it is much, much more convenient and performant for them to not be.

In this case, I think Transact Charlie's proposal for your operational tables is a good one.

But I would add an index (not necessarily unique) to CompetitorName in the Competitors table to support efficient joins on CompetitorName for the purposes of integration (loading of data from external sources), and I would put an interface table into the mix: CompetitionResults.

CompetitionResults should contain whatever data your competition results have in it. The point of an interface table like this one is to make it as quick and easy as possible to truncate and reload it from an Excel sheet or a CSV file, or whatever form you have that data in.

That interface table should not be considered part of the normalized set of operational tables. Then you can join with CompetitionResults as suggested by Richard, to insert records into Competitors that don't already exist, and update the ones that do (for example if you actually have more information about competitors, like their phone number or email address).

One thing I would note - in reality, Competitor Name, it seems to me, is very unlikely to be unique in your data. In 200,000 competitors, you may very well have 2 or more David Smiths, for example. So I would recommend that you collect more information from competitors, such as their phone number or an email address, or something which is more likely to be unique.

Your operational table, Competitors, should just have one column for each data item that contributes to a composite natural key; for example it should have one column for a primary email address. But the interface table should have a slot for old and new values for a primary email address, so that the old value can be use to look up the record in Competitors and update that part of it to the new value.

So CompetitionResults should have some "old" and "new" fields - oldEmail, newEmail, oldPhone, newPhone, etc. That way you can form a composite key, in Competitors, from CompetitorName, Email, and Phone.

Then when you have some competition results, you can truncate and reload your CompetitionResults table from your excel sheet or whatever you have, and run a single, efficient insert to insert all the new competitors into the Competitors table, and single, efficient update to update all the information about the existing competitors from the CompetitionResults. And you can do a single insert to insert new rows into the CompetitionCompetitors table. These things can be done in a ProcessCompetitionResults stored procedure, which could be executed after loading the CompetitionResults table.

That's a sort of rudimentary description of what I've seen done over and over in the real world with Oracle Applications, SAP, PeopleSoft, and a laundry list of other enterprise software suites.

One last comment I'd make is one I've made before on SO: If you create a foreign key that insures that a Competitor exists in the Competitors table before you can add a row with that Competitor in it to CompetitionCompetitors, make sure that foreign key is set to cascade updates and deletes. That way if you need to delete a competitor, you can do it and all the rows associated with that competitor will get automatically deleted. Otherwise, by default, the foreign key will require you to delete all the related rows out of CompetitionCompetitors before it will let you delete a Competitor.

(Some people think non-cascading foreign keys are a good safety precaution, but my experience is that they're just a freaking pain in the butt that are more often than not simply a result of an oversight and they create a bunch of make work for DBA's. Dealing with people accidentally deleting stuff is why you have things like "are you sure" dialogs and various types of regular backups and redundant data sources. It's far, far more common to actually want to delete a competitor, whose data is all messed up for example, than it is to accidentally delete one and then go "Oh no! I didn't mean to do that! And now I don't have their competition results! Aaaahh!" The latter is certainly common enough, so, you do need to be prepared for it, but the former is far more common, so the easiest and best way to prepare for the former, imo, is to just make foreign keys cascade updates and deletes.)

In case, it is a django backend application, you can do something like this.

docker exec -it container_id python manage.py dbshell

You need to install the Chrome driver. You can install this package using NuGet as shown below:

Here is an enhancement to vc-74's post that handles commas the same way Excel does. Excel puts quotes around data if the data has a comma but doesn't quote if the data doesn't have a comma.

    public static string ToCsv(this DataTable inDataTable, bool inIncludeHeaders = true)
    {
        var builder = new StringBuilder();
        var columnNames = inDataTable.Columns.Cast<DataColumn>().Select(column => column.ColumnName);
        if (inIncludeHeaders)
            builder.AppendLine(string.Join(",", columnNames));
        foreach (DataRow row in inDataTable.Rows)
        {
            var fields = row.ItemArray.Select(field => field.ToString().WrapInQuotesIfContains(","));
            builder.AppendLine(string.Join(",", fields));
        }

        return builder.ToString();
    }

    public static string WrapInQuotesIfContains(this string inString, string inSearchString)
    {
        if (inString.Contains(inSearchString))
            return "\"" + inString+ "\"";
        return inString;
    }

you can get filename by uri with simple way

Retrieving file information

fun get_filename_by_uri(uri : Uri) : String{
    contentResolver.query(uri, null, null, null, null).use { cursor ->
        cursor?.let {
            val nameIndex = it.getColumnIndex(OpenableColumns.DISPLAY_NAME)
            it.moveToFirst()
            return it.getString(nameIndex)
        }
    }
    return ""
}

and easy to read it by using

contentResolver.openInputStream(uri)

Yes, SERIAL is the equivalent function.

CREATE TABLE foo (
id SERIAL,
bar varchar);

INSERT INTO foo (bar) values ('blah');
INSERT INTO foo (bar) values ('blah');

SELECT * FROM foo;

1,blah
2,blah

SERIAL is just a create table time macro around sequences. You can not alter SERIAL onto an existing column.

There is a blog post with brief source code sample about how misuse of IEnumerable<T> can dramatically impact LINQ query performance: Entity Framework: IQueryable vs. IEnumerable.

If we dig deeper and look into the sources, we can see that there are obviously different extension methods are perfomed for IEnumerable<T>:

// Type: System.Linq.Enumerable
// Assembly: System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
// Assembly location: C:\Windows\Microsoft.NET\Framework\v4.0.30319\System.Core.dll
public static class Enumerable
{
    public static IEnumerable<TSource> Where<TSource>(
        this IEnumerable<TSource> source, 
        Func<TSource, bool> predicate)
    {
        return (IEnumerable<TSource>) 
            new Enumerable.WhereEnumerableIterator<TSource>(source, predicate);
    }
}

and IQueryable<T>:

// Type: System.Linq.Queryable
// Assembly: System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
// Assembly location: C:\Windows\Microsoft.NET\Framework\v4.0.30319\System.Core.dll
public static class Queryable
{
    public static IQueryable<TSource> Where<TSource>(
        this IQueryable<TSource> source, 
        Expression<Func<TSource, bool>> predicate)
    {
        return source.Provider.CreateQuery<TSource>(
            Expression.Call(
                null, 
                ((MethodInfo) MethodBase.GetCurrentMethod()).MakeGenericMethod(
                    new Type[] { typeof(TSource) }), 
                    new Expression[] 
                        { source.Expression, Expression.Quote(predicate) }));
    }
}

The first one returns enumerable iterator, and the second one creates query through the query provider, specified in IQueryable source.

SELECT * 
FROM tbl 
WHERE myDate BETWEEN #date one# AND #date two#;

You need to use brackets when using the fileExists step in an if condition or assign the returned value to a variable

Using variable:

def exists = fileExists 'file'

if (exists) {
    echo 'Yes'
} else {
    echo 'No'
}

Using brackets:

if (fileExists('file')) {
    echo 'Yes'
} else {
    echo 'No'
}

This one works fine for me with apis

import requests

data={'Id':id ,'name': name}
r = requests.post( url = 'https://apiurllink', data = data)

Use Admin :
    use admin

    pwd: "test@123",
    roles: [ 
    { 
    role: "readWriteAnyDatabase", 
    db: "admin" 
    }, 
    {
    "role" : "dbAdminAnyDatabase",
    "db" : "admin"
    },
    {
    "role" : "clusterAdmin",
    "db" : "admin"
    },
    "userAdminAnyDatabase" 
    ]
    }
    )

Yup.

Measure-Command { .\do_something.ps1 }

Note that one minor downside of Measure-Command is that you see no stdout output.

[Update, thanks to @JasonMArcher] You can fix that by piping the command output to some commandlet that writes to the host, e.g. Out-Default so it becomes:

Measure-Command { .\do_something.ps1 | Out-Default }

Another way to see the output would be to use the .NET Stopwatch class like this:

$sw = [Diagnostics.Stopwatch]::StartNew()
.\do_something.ps1
$sw.Stop()
$sw.Elapsed

All these results in null:

document.getElementById('volume');
document.getElementById('bytesLoaded');
document.getElementById('startBytes');
document.getElementById('bytesTotal');

You need to do a null check in updateHTML like this:

function updateHTML(elmId, value) {
  var elem = document.getElementById(elmId);
  if(typeof elem !== 'undefined' && elem !== null) {
    elem.innerHTML = value;
  }
}

class Base
{
    struct FooSecurity{};
};

template<class Type>
class Foo
{
    typename Type::FooSecurity If_You_Are_Reading_This_You_Tried_To_Create_An_Instance_Of_Foo_For_An_Invalid_Type;
};

Make sure derived classes inherit the FooSecurity structure and the compiler will get upset in all the right places.

Perhaps the question is getting old, but I hope my code will help someone.

I have had to unpack a .ab-file, too and found this post while looking for an answer. My suggested solution is Android Backup Extractor, a free Java tool for Windows, Linux and Mac OS.

Make sure to take a look at the README, if you encounter a problem. You might have to download further files, if your .ab-file is password-protected.

Usage:

java -jar abe.jar [-debug] [-useenv=yourenv] unpack <backup.ab> <backup.tar> [password]

Example:

Let's say, you've got a file test.ab, which is not password-protected, you're using Windows and want the resulting .tar-Archive to be called test.tar. Then your command should be:

java.exe -jar abe.jar unpack test.ab test.tar ""

OK I did it finally:

Sub CountUniqueRecords()
Dim Array() as variant, UniqueArray() as variant, UniqueNo as Integer,      
Dim i as integer, j as integer, k as integer

Redim UnquiArray(1)

k= Upbound(array)

For i = 1 To k
For j = 1 To UniqueNo + 1
  If Array(i) = UniqueArray(j) Then GoTo Nx
Next j
  UniqueNo = UniqueNo + 1
  ReDim Preserve UniqueArray(UniqueNo + 1)
  UniqueArray(UniqueNo) = Array(i)
Nx:
Next i

MsgBox UniqueNo

End Sub

Addition to BeNdErR's answer:
The "other TEXT" element should have float:none, like:

    <div style="width:100%;">_x000D_
        <div style="float:left;width:30%; background:red;">...something something something  random text</div>_x000D_
        <div style="float:none; background:yellow;"> text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text  </div>_x000D_
    </div>

This saved my life--->

1. set this line

   ListView.setDescendantFocusability(ViewGroup.FOCUS_AFTER_DESCENDANTS);

2. Then in your manifest in activity tag type this-->

   <activity android:windowSoftInputMode="adjustPan">

Your usual intent

This is a way that also able you to replace default separator with any characters:

val myNumber = NumberFormat.getNumberInstance(Locale.US)
   .format(123456789)
   .replace(",", "?")

No. PDO queries are not prepared on the client side. PDO simply sends the SQL query and the parameters to the database server. The database is what does the substitution (of the ?'s). You have two options:

• Use your DB's logging function (but even then it's normally shown as two separate statements (ie, "not final") at least with Postgres)
• Output the SQL query and the paramaters and piece it together yourself

pgpdump (https://www.lirnberger.com/tools/pgpdump/) is a tool that you can use to inspect pgp blocks.

It is not user friendly, and fairly technical, however,

• it parses public or private keys (without warning)
• it does not modify any keyring (sometimes it is not so clear what gpg does behind the hood, in my experience)
• it prints all packets, specifically userid's packets which shows the various text data about the keys.

unfortunately it does not read stdin : /

You don't have to do a replace, you can get the length of the children text and subtract that from the overall length, and slice into the original text. That should be substantially faster.

function getValue(obj)
{  
   // it will return the selected text
   // obj variable will contain the object of check box
   var text = obj.options[obj.selectedIndex].innerHTML ; 

}

HTML Snippet

 <asp:DropDownList ID="ddl" runat="server" CssClass="ComboXXX" 
  onchange="getValue(this)">
</asp:DropDownList>

The Solution i found is not for ASPX but for Razor, but quite comperable issue.

I resolved it by adding the AntiForgery to the request. The HTML Helper does not create a HTML id with the call

@Html.AntiForgeryToken()

In order to add the token to the postrequest i just added the AntiForgery id to the hidden field with jquery:

$("input[name*='__RequestVerificationToken']").attr('id', '__AjaxAntiForgeryForm');

This caused the controller to accept the request with the [ValidateAntiForgeryToken] attribute

When you do from socket import * python is loading a socket module to the current namespace. Thus you can use module's members as if they are defined within your current python module.

When you do import socket, a module is loaded in a separate namespace. When you are accessing its members, you should prefix them with a module name. For example, if you want to refer to a socket class, you will need to write client_socket = socket.socket(socket.AF_INET,socket.SOCK_DGRAM).

As for the problem with timeout - all you need to do is to change except socket.Timeouterror: to except timeout:, since timeout class is defined inside socket module and you have imported all its members to your namespace.

You can use .attr() as a part of however you plan to toggle it:

$("button").attr("aria-expanded","true");

Even array2.extend(array1) will work.

Inside a Fragment subclass you have to use getFragmentManager in place of getSupportFragmentManager. You will get the support one if the import are from the support library.

I would apply this rule to all input fields of type text, so it doesn't need to be duplicated later:

input[type=text]::-ms-clear { display: none; }

One can even get less specific by using just:

::-ms-clear { display: none; }

I have used the later even before adding this answer, but thought that most people would prefer to be more specific than that. Both solutions work fine.

Try this:

$(":focus").each(function() {
    alert("Focused Elem_id = "+ this.id );
});

To do this job in storyboard (Interface Builder Inspector)

With help of IBDesignable, we can add more options to Interface Builder Inspector for UINavigationController and tweak them on storyboard. First, add the following code to your project.

@IBDesignable extension UINavigationController {
    @IBInspectable var barTintColor: UIColor? {
        set {
            navigationBar.barTintColor = newValue
        }
        get {
            guard  let color = navigationBar.barTintColor else { return nil }
            return color
        }
    }

    @IBInspectable var tintColor: UIColor? {
        set {
            navigationBar.tintColor = newValue
        }
        get {
            guard  let color = navigationBar.tintColor else { return nil }
            return color
        }
    }

    @IBInspectable var titleColor: UIColor? {
        set {
            guard let color = newValue else { return }
            navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: color]
        }
        get {
            return navigationBar.titleTextAttributes?["NSForegroundColorAttributeName"] as? UIColor
        }
    }
}

Then simply set the attributes for UINavigationController on storyboard.

Since the question is so popular, it may be useful to add on what to do if you want to control the type property name and its value.

The long way is to write custom JsonConverters to handle (de)serialization by manually checking and setting the type property.

A simpler way is to use JsonSubTypes, which handles all the boilerplate via attributes:

[JsonConverter(typeof(JsonSubtypes), "Sound")]
[JsonSubtypes.KnownSubType(typeof(Dog), "Bark")]
[JsonSubtypes.KnownSubType(typeof(Cat), "Meow")]
public class Animal
{
    public virtual string Sound { get; }
    public string Color { get; set; }
}

public class Dog : Animal
{
    public override string Sound { get; } = "Bark";
    public string Breed { get; set; }
}

public class Cat : Animal
{
    public override string Sound { get; } = "Meow";
    public bool Declawed { get; set; }
}

Currently there is no way to precreate an SQLite database to ship with your apk. The best you can do is save the appropriate SQL as a resource and run them from your application. Yes, this leads to duplication of data (same information exists as a resrouce and as a database) but there is no other way right now. The only mitigating factor is the apk file is compressed. My experience is 908KB compresses to less than 268KB.

The thread below has the best discussion/solution I have found with good sample code.

http://groups.google.com/group/android-developers/msg/9f455ae93a1cf152

I stored my CREATE statement as a string resource to be read with Context.getString() and ran it with SQLiteDatabse.execSQL().

I stored the data for my inserts in res/raw/inserts.sql (I created the sql file, 7000+ lines). Using the technique from the link above I entered a loop, read the file line by line and concactenated the data onto "INSERT INTO tbl VALUE " and did another SQLiteDatabase.execSQL(). No sense in saving 7000 "INSERT INTO tbl VALUE "s when they can just be concactenated on.

It takes about twenty seconds on the emulator, I do not know how long this would take on a real phone, but it only happens once, when the user first starts the application.

Well I think you just need to add a quantifier to each pattern. Also the carriage-return thing is a little funny:

text.replace(/[^a-z0-9]+|\s+/gmi, " ");

edit The \s thing matches \r and \n too.

To create sets you can use a varargs factory method instead of double-brace initialisation:

public static Set<T> setOf(T ... elements) {
    return new HashSet<T>(Arrays.asList(elements));
}

The Google Collections library has lots of convenience methods like this, as well as loads of other useful functionality.

As for the idiom's obscurity, I encounter it and use it in production code all the time. I'd be more concerned about programmers who get confused by the idiom being allowed to write production code.

To get the row numbers where at least one item is larger than 15:

>>> np.where(np.any(e>15, axis=1))
(array([1, 2], dtype=int64),)

The HTML2PDF and HTML2PS that was originally mentioned in opening post was talking about a 2009 package with this link

But there is a better HTML2PDF

It is based on TCPDF though it is partly in French.

You can have table headers or footers that repeat on the pages and have page numbers and total pages. See its examples. I have been using it for over three years and recommend it.

The difference is not just for Chrome but for most of the web browsers.

F5 refreshes the web page and often reloads the same page from the cached contents of the web browser. However, reloading from cache every time is not guaranteed and it also depends upon the cache expiry.

Shift + F5 forces the web browser to ignore its cached contents and retrieve a fresh copy of the web page into the browser.

Shift + F5 guarantees loading of latest contents of the web page.
However, depending upon the size of page, it is usually slower than F5.

You may want to refer to: What requests do browsers' "F5" and "Ctrl + F5" refreshes generate?

this works on android (at least on stock gingerbread browser):

<body onload="document.body.style.height=(2*window.innerHeight-window.outerHeight)+'px';"></body>

further if you want to disable scrolling you can use

setInterval(function(){window.scrollTo(1,0)},50);

You Can Wrap your widget with Flexible Widget and than you can set property of Text using overflow property of Text Widget. you have to set TextOverflow.clip for example:-

Flexible
(child: new Text("This is Dummy Long Text",
 style: TextStyle(
 fontFamily: "Roboto",
 color: Colors.black,
 fontSize: 10.0,
 fontWeight: FontWeight.bold),
 overflow: TextOverflow.clip,),)

hope this help someone :)

The key is calling the parent's method using super.methodName();

class A {
    // A protected method
    protected doStuff()
    {
        alert("Called from A");
    }

    // Expose the protected method as a public function
    public callDoStuff()
    {
        this.doStuff();
    }
}

class B extends A {

    // Override the protected method
    protected doStuff()
    {
        // If we want we can still explicitly call the initial method
        super.doStuff();
        alert("Called from B");
    }
}

var a = new A();
a.callDoStuff(); // Will only alert "Called from A"

var b = new B()
b.callDoStuff(); // Will alert "Called from A" then "Called from B"

Try it here

This should solve your problem:

select replace(to_char(a, '90D90'),'.00','')
from
(
select 50 a from dual
union
select 50.57 from dual
union
select 5.57 from dual
union
select 0.35 from dual
union
select 0.4 from dual
);

Give a look also as this SQL Fiddle for test.

If the message is "n commits behind master."

You need to rebase your dev branch with master. You got the above message because after checking out dev branch from master, the master branch got new commit and has moved ahead. You need to get those new commits to your dev branch.

Steps:

git checkout master
git pull        #this will update your local master
git checkout yourDevBranch
git rebase master

there can be some merge conflicts which you have to resolve.

In your example there is no big difference between str -> str and Function.identity() since internally it is simply t->t.

But sometimes we can't use Function.identity because we can't use a Function. Take a look here:

List<Integer> list = new ArrayList<>();
list.add(1);
list.add(2);

this will compile fine

int[] arrayOK = list.stream().mapToInt(i -> i).toArray();

but if you try to compile

int[] arrayProblem = list.stream().mapToInt(Function.identity()).toArray();

you will get compilation error since mapToInt expects ToIntFunction, which is not related to Function. Also ToIntFunction doesn't have identity() method.

Boosting your maven-compiler-plugin to 3.8.0 seems to be necessary but not sufficient. If you're still having problems, you should also make sure your JAVA_HOME environment variable is set to Java 10 (or 11) if you're running from the command line. (The error message you get won't tell you this.) Or if you're running from an IDE, you need to make sure it is set to run maven with your current JDK.

This is what I did to integrate Identity with an existing database.

1. Create a sample MVC project with MVC template. This has all the code needed for Identity implementation - Startup.Auth.cs, IdentityConfig.cs, Account Controller code, Manage Controller, Models and related views.

2. Install the necessary nuget packages for Identity and OWIN. You will get an idea by seeing the references in the sample Project and the answer by @Sam

3. Copy all these code to your existing project. Please note don't forget to add the "DefaultConnection" connection string for Identity to map to your database. Please check the ApplicationDBContext class in IdentityModel.cs where you will find the reference to "DefaultConnection" connection string.

4. This is the SQL script I ran on my existing database to create necessary tables:

5. Check and solve any remaining errors and you are done. Identity will handle the rest :)

none of the above answers worked for me. This one did:

=QUERY(Copy!A1:AP, "select AP, E, F, AO where AP="&E1&" ",1)

Assume you have one table with name 'table1'. It contain one column 'col1' with varchar type. Query to crate table is give below

CREATE TABLE `table1` (
    `col1` VARCHAR(50) NULL DEFAULT NULL
)

Now if you want to insert number from 1 to 50 in that table then use following stored procedure

DELIMITER $$  
CREATE PROCEDURE ABC()

   BEGIN
      DECLARE a INT Default 1 ;
      simple_loop: LOOP         
         insert into table1 values(a);
         SET a=a+1;
         IF a=51 THEN
            LEAVE simple_loop;
         END IF;
   END LOOP simple_loop;
END $$

To call that stored procedure use

CALL `ABC`()

Of course you can sample each row:

sapply (1:4, function (row) df1[row,]<<-sample(df1[row,]))

will shuffle the rows itself, so the number of 1's in each row doesn't change. Small changes and it also works great with columns, but this is a exercise for the reader :-P

to solve the error like this one: "list object is not callable in python" even you are changing the variable name then please restart the kernel in Python Jutyter Notebook if you are using it or simply restart the IDE.

I hope this will work. Thank you!!!

I wrote this ES6 Class which does the Job.

class SvgToPngConverter {
  constructor() {
    this._init = this._init.bind(this);
    this._cleanUp = this._cleanUp.bind(this);
    this.convertFromInput = this.convertFromInput.bind(this);
  }

  _init() {
    this.canvas = document.createElement("canvas");
    this.imgPreview = document.createElement("img");
    this.imgPreview.style = "position: absolute; top: -9999px";

    document.body.appendChild(this.imgPreview);
    this.canvasCtx = this.canvas.getContext("2d");
  }

  _cleanUp() {
    document.body.removeChild(this.imgPreview);
  }

  convertFromInput(input, callback) {
    this._init();
    let _this = this;
    this.imgPreview.onload = function() {
      const img = new Image();
      _this.canvas.width = _this.imgPreview.clientWidth;
      _this.canvas.height = _this.imgPreview.clientHeight;
      img.crossOrigin = "anonymous";
      img.src = _this.imgPreview.src;
      img.onload = function() {
        _this.canvasCtx.drawImage(img, 0, 0);
        let imgData = _this.canvas.toDataURL("image/png");
        if(typeof callback == "function"){
            callback(imgData)
        }
        _this._cleanUp();
      };
    };

    this.imgPreview.src = input;
  }
}

Here is how you use it

let input = "https://restcountries.eu/data/afg.svg"
new SvgToPngConverter().convertFromInput(input, function(imgData){
    // You now have your png data in base64 (imgData). 
    // Do what ever you wish with it here.
});

If you want a vanilla JavaScript version, you could head over to Babel website and transpile the code there.

Another possibility would be to set the Working Directory under the debugging options to be the directory that has that DLL.

Edit: I was going to mention using a batch file to start Visual Studio (and set the PATH variable in the batch file). So then did a bit of searching and see that this exact same question was asked not long ago in this post. The answer suggests the batch file option as well as project settings that apparently may do the job (I did not test it).

PHP is a dynamic language, so you can't overload methods. You have to check the types of your argument like this:

class Student 
{
   protected $id;
   protected $name;
   // etc.

   public function __construct($idOrRow){
    if(is_int($idOrRow))
    {
        $this->id = $idOrRow;
        // other members are still uninitialized
    }
    else if(is_array($idOrRow))
    {
       $this->id = $idOrRow->id;
       $this->name = $idOrRow->name;
       // etc.  
    }
}

To remote server

mysqldump mydbname | ssh host2 "mysql mydbcopy"

To local server

mysqldump mydbname | mysql mydbcopy

A more modern approach would be to use the grid property.

  display: grid;_x000D_

Yes, the constant CI_VERSION will give you the current CodeIgniter version number. It's defined in: /system/codeigniter/CodeIgniter.php As of CodeIgniter 2, it's defined in /system/core/CodeIgniter.php

For example,

echo CI_VERSION; // echoes something like 1.7.1

Try this one -

CREATE PROC [dbo].[getVoucherNo]
AS BEGIN

     DECLARE 
            @Prefix VARCHAR(10) = 'J'
          , @startFrom INT = 1
          , @maxCode VARCHAR(100)
          , @sCode INT

     IF EXISTS(
          SELECT 1 
          FROM dbo.Journal_Entry
     ) BEGIN

          SELECT @maxCode = CAST(MAX(CAST(SUBSTRING(Voucher_No,LEN(@startFrom)+1,ABS(LEN(Voucher_No)- LEN(@Prefix))) AS INT)) AS varchar(100)) 
          FROM dbo.Journal_Entry;

          SELECT @Prefix + 
               CAST(LEN(LEFT(@maxCode, 10) + 1) AS VARCHAR(10)) + -- !!! possible problem here
               CAST(@maxCode AS VARCHAR(100))

     END
     ELSE BEGIN

          SELECT (@Prefix + CAST(@startFrom AS VARCHAR)) 

     END

END

When you want to create a new user:

Here is a very quick and simple solution:

self.navigationController.hidesBarsOnTap = YES;

This will work on single tap instead of double tap. Also it will change the behavior for the navigation controller even after pushing or popping the current view controller.

You can always modify this behavior in your controller within the viewWillAppear: and viewWillDisappear: actions if you would like to set the behavior only for a single view controller.

Here is the documentation:

I imagine this like that:

<html>
<head>
<script>
var frame_loaded = 0;
function setFrameLoaded()
{
   frame_loaded = 1;
   alert("Iframe is loaded");
}
$('#click').click(function(){
   if(frame_loaded == 1)
    console.log('iframe loaded')
   } else {
    console.log('iframe not loaded')
   }
})
</script>
</head>
<button id='click'>click me</button>

<iframe id='MainPopupIframe' onload='setFrameLoaded();' src='http://...' />...</iframe>

Common Lisp

For a good reference of CL check out Common Lisp the Language, 2nd Edition

One-liner solution here:

var1 = locals().get("var1", "default value")

Instead of having NameError, this solution will set var1 to default value if var1 hasn't been defined yet.

Here's how it looks like in Python interactive shell:

>>> var1
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'var1' is not defined
>>> var1 = locals().get("var1", "default value 1")
>>> var1
'default value 1'
>>> var1 = locals().get("var1", "default value 2")
>>> var1
'default value 1'
>>>

For reference, cursor.rowcount will only return on CREATE, UPDATE and DELETE statements:

 |  rowcount
 |      This read-only attribute specifies the number of rows the last DML statement
 |      (INSERT, UPDATE, DELETE) affected.  This is set to -1 for SELECT statements.

There are a few routes. One, the most simple, would involve making that into a form; when it submits you react to POST data and delete the image using unlink

DISCLAIMER: This is not secure. An attacker could use this code to delete any file on your server. You must expand on this demonstration code to add some measure of security, otherwise you can expect bad things.

Each image's display markup would contain a form something like this:

echo '<form method="post">';
  echo '<input type="hidden" value="'.$file.'" name="delete_file" />';
  echo '<input type="submit" value="Delete image" />';
echo '</form>';

...and at at the top of that same PHP file:

if (array_key_exists('delete_file', $_POST)) {
  $filename = $_POST['delete_file'];
  if (file_exists($filename)) {
    unlink($filename);
    echo 'File '.$filename.' has been deleted';
  } else {
    echo 'Could not delete '.$filename.', file does not exist';
  }
}
// existing code continues below...

You can elaborate on this by using javascript: instead of submitting the form, you could send an AJAX request. The server-side code would look rather similar to this.

The hexadecimal value you are looking for is %2B

To get it automatically in PHP run your string through urlencode($stringVal). And then run it rhough urldecode($stringVal) to get it back.

If you want the JavaScript to handle it, use escape( str )

Edit

After @bobince's comment I did more reading and he is correct. Use encodeURIComponent(str) and decodeURIComponent(str). Escape will not convert the characters, only escape them with \'s

Open vscode.

Press ctrl,.

The setting is "editor.fontFamily".

On Linux to get a list of fonts (and their names which you have to use) run this in another shell:

fc-list | awk '{$1=""}1' | cut -d: -f1 | sort| uniq

You can specify a list of fonts, to have fallback values in case a font is missing.

Case Sensitivity will cause this problem, too.

@MyVariable and @myvariable are the same variables in SQL Server Man. Studio and will work. However, these variables will result in a "Must declare the scalar variable "@MyVariable" in Visual Studio (C#) due to case-sensitivity differences.

Change the database.php file from

just use onkeydown="return false" to the control tag like shown below, it will not accept values from user.

    <asp:TextBox ID="txtDate" runat="server" AutoPostBack="True"

To conditionally check the length of the string, use CASE.

My experience with MATMUL and DOT

I was constantly getting "ValueError: Shape of passed values is (200, 1), indices imply (200, 3)" when trying to use MATMUL. I wanted a quick workaround and found DOT to deliver the same functionality. I don't get any error using DOT. I get the correct answer

with MATMUL

X.shape
>>>(200, 3)

type(X)

>>>pandas.core.frame.DataFrame

w

>>>array([0.37454012, 0.95071431, 0.73199394])

YY = np.matmul(X,w)

>>>  ValueError: Shape of passed values is (200, 1), indices imply (200, 3)"

with DOT

YY = np.dot(X,w)
# no error message
YY
>>>array([ 2.59206877,  1.06842193,  2.18533396,  2.11366346,  0.28505879, …

YY.shape

Check your real my.ini file location and set --defaults-file="location" with this command

mysql --defaults-file="C:\MYSQL\my.ini" -u root -p

This solution is permanently for your cmd Screen.

I have got the solution for my query:

i have done something like this:

cell.innerHTML="<img height=40 width=40 alt='' src='<%=request.getContextPath()%>/writeImage.htm?' onerror='onImgError(this);' onLoad='setDefaultImage(this);'>"

function setDefaultImage(source){
        var badImg = new Image();
        badImg.src = "video.png";
        var cpyImg = new Image();
        cpyImg.src = source.src;

        if(!cpyImg.width)
        {
            source.src = badImg.src;
        }

    }


    function onImgError(source){
        source.src = "video.png";
        source.onerror = ""; 
        return true; 
    } 

This way it's working in all browsers.

Click the database symbol with the plus sign (shown in the below picture). Enter a name and click Apply.

This worked in MySQL Workbench 6.0

What if you hooked the window resize event:

$(window).resize(function() 
{    
    chart.setSize(
       $(document).width(), 
       $(document).height()/2,
       false
    );   
});

See example fiddle here.

Highcharts API Reference : setSize().

JavaScript 1.0

window.location.href = window.location.pathname + window.location.search + window.location.hash;
// creates a history entry

JavaScript 1.1

window.location.replace(window.location.pathname + window.location.search + window.location.hash);
// does not create a history entry

JavaScript 1.2

window.location.reload(false); 
// If we needed to pull the document from
//  the web-server again (such as where the document contents
//  change dynamically) we would pass the argument as 'true'.

Reason of comments:

1. Comment out elements temporarily rather than removing them, especially if they've been left unfinished.
2. Write notes or reminders to yourself inside your actual HTML documents.
3. Create notes for other scripting languages like JavaScript which requires them

HTML Comments

<!-- Everything is invisible  -->

You don't need to explicitly use qualifiers like item.photo == '' or item.photo != ''. Like in JavaScript, an empty string will be evaluated as false.

Your views will be much cleaner and readable as well.

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.0/angular.min.js"></script>_x000D_
<div ng-app init="item = {photo: ''}">_x000D_
   <div ng-if="item.photo"> show if photo is not empty</div>_x000D_
   <div ng-if="!item.photo"> show if photo is empty</div>_x000D_
  _x000D_
   <input type=text ng-model="item.photo" placeholder="photo" />_x000D_
</div

Updated to remove bug in Angular

I would generally recommend using element.attachEvent (IE) or element.addEventListener (other browsers) over setting the onclick event directly as the latter will replace any existing event handlers for that element.

attachEvent / addEventListening allow multiple event handlers to be created.

Using Console.WriteLine( "Test" ); is able to write log messages to the Output Window (View Menu --> Output) in Visual Studio for a Windows Forms/WPF project.

However, I encountered a case where it was not working and only System.Diagnostics.Debug.WriteLine( "Test" ); was working. I restarted Visual Studio and Console.WriteLine() started working again. Seems to be a Visual Studio bug.

You could also try listing the css in the style sheet as !important

Note that Math.hypot is part of the ES2015 standard. There's also a good polyfill on the MDN doc for this feature.

So getting the distance becomes as easy as Math.hypot(x2-x1, y2-y1).

Not sure if this is against private APIs/properties but using KVC works for me on ios8

UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:@"Dont care what goes here, since we're about to change below" message:@"" preferredStyle:UIAlertControllerStyleActionSheet];
NSMutableAttributedString *hogan = [[NSMutableAttributedString alloc] initWithString:@"Presenting the great... Hulk Hogan!"];
[hogan addAttribute:NSFontAttributeName
              value:[UIFont systemFontOfSize:50.0]
              range:NSMakeRange(24, 11)];
[alertVC setValue:hogan forKey:@"attributedTitle"];



UIAlertAction *button = [UIAlertAction actionWithTitle:@"Label text" 
                                        style:UIAlertActionStyleDefault
                                        handler:^(UIAlertAction *action){
                                                    //add code to make something happen once tapped
}];
UIImage *accessoryImage = [UIImage imageNamed:@"someImage"];
[button setValue:accessoryImage forKey:@"image"];

For the record, it is possible to change alert action's font as well, using those private APIs. Again, it may get you app rejected, I have not yet tried to submit such code.

let alert = UIAlertController(title: nil, message: nil, preferredStyle: .ActionSheet)

let action = UIAlertAction(title: "Some title", style: .Default, handler: nil)
let attributedText = NSMutableAttributedString(string: "Some title")

let range = NSRange(location: 0, length: attributedText.length)
attributedText.addAttribute(NSKernAttributeName, value: 1.5, range: range)
attributedText.addAttribute(NSFontAttributeName, value: UIFont(name: "ProximaNova-Semibold", size: 20.0)!, range: range)

alert.addAction(action)

presentViewController(alert, animated: true, completion: nil)

// this has to be set after presenting the alert, otherwise the internal property __representer is nil
guard let label = action.valueForKey("__representer")?.valueForKey("label") as? UILabel else { return }
label.attributedText = attributedText

For Swift 4.2 in XCode 10 and up the last 2 lines are now:

guard let label = (action!.value(forKey: "__representer")as? NSObject)?.value(forKey: "label") as? UILabel else { return }
        label.attributedText = attributedText

I'd wrap the dictionary in another class:

public class MyListDictionary
{

    private Dictionary<string, List<string>> internalDictionary = new Dictionary<string,List<string>>();

    public void Add(string key, string value)
    {
        if (this.internalDictionary.ContainsKey(key))
        {
            List<string> list = this.internalDictionary[key];
            if (list.Contains(value) == false)
            {
                list.Add(value);
            }
        }
        else
        {
            List<string> list = new List<string>();
            list.Add(value);
            this.internalDictionary.Add(key, list);
        }
    }

}

If the list is fixed in the script, I like the following the best:

validate() {
    grep -F -q -x "$1" <<EOF
item 1
item 2
item 3
EOF
}

Then use validate "$x" to test if $x is allowed.

If you want a one-liner, and don't care about whitespace in item names, you can use this (notice -w instead of -x):

validate() { echo "11 22 33" | grep -F -q -w "$1"; }

Notes:

• This is POSIX sh compliant.
• validate does not accept substrings (remove the -x option to grep if you want that).
• validate interprets its argument as a fixed string, not a regular expression (remove the -F option to grep if you want that).

Sample code to exercise the function:

for x in "item 1" "item2" "item 3" "3" "*"; do
    echo -n "'$x' is "
    validate "$x" && echo "valid" || echo "invalid"
done

You can use JPGraph and Graphpite

enclose your modal body inside a form with an id="myform"

and then

 $("#activatesimModal").on("hidden.bs.modal",function(){
        myform.reset();
});

should do the trick

{
  "number" : ["1","2","3"],
  "alphabet" : ["a", "b", "c"]
}

There are two answers above up-to-now and they are both long (and tl;dr too short IMHO), so I write summary from my experience starting to use new java.time library (applicable as noted in other answers to Java version 8+). ISO 8601 sets standard way to write dates: YYYY-MM-DD so the format of date-time is only as below (could be 0, 3, 6 or 9 digits for milliseconds) and no formatting string necessary:

import java.time.Instant;
public static void main(String[] args) {
    String date="2010-10-02T12:23:23Z";
    try {
        Instant myDate = Instant.parse(date);
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

I did not need it, but as getting year is in code from the question, then:
it is trickier, cannot be done from Instant directly, can be done via Calendar in way of questions Get integer value of the current year in Java and Converting java.time to Calendar but IMHO as format is fixed substring is more simple to use:

myDate.toString().substring(0,4);

getting username in MAC terminal is easy...

I generally use whoami in terminal...

For example, in this case, I needed that to install Tomcat Server...

old thread, but here's an updated possibility for ie8 and ff3.5 users:

function isHTMLElement(o) {
    return (o.constructor.toString().search(/\object HTML.+Element/) > -1);
}

Yes, in your formula, you can cbind the numeric variables to be aggregated:

aggregate(cbind(x1, x2) ~ year + month, data = df1, sum, na.rm = TRUE)
   year month         x1          x2
1  2000     1   7.862002   -7.469298
2  2001     1 276.758209  474.384252
3  2000     2  13.122369 -128.122613
...
23 2000    12  63.436507  449.794454
24 2001    12 999.472226  922.726589

See ?aggregate, the formula argument and the examples.

The only real clean way to uninstall VS (Visual Studio, whatever version it is) is to completely reinstall the whole OS. If you don't, more compatibility problems might surface.

Permanent solution

Starting from scratch (clean install, VS never installed on the OS), the best way to avoid all those problems is to install and run VS from a VM (virtual machine) as stated by Default in the comments above. This way, and as long as Microsoft doesn't do anything to improve its whole platform to be more user-friendly, switching from a version to another will be quick and easy and the main partition of the HDD (or SSD in my case) won't be filed with all the garbage that VS leaves behind.

Of course, the disadvantage is speed. The program will be slower in pretty much every way. But honestly, who uses VS for its speed? Even on the latest enthusiast-platforms, it takes ages to install. Even if VS might start up faster on a high-end SSD, it's just slow.

-w is the GCC-wide option to disable warning messages.

This worked for me.

You can write directly to an event log. Check the following links:
http://support.microsoft.com/kb/307024
http://msdn.microsoft.com/en-us/library/system.diagnostics.eventlog.aspx

And here's the sample from MSDN:

using System;
using System.Diagnostics;
using System.Threading;

class MySample{

    public static void Main(){

        // Create the source, if it does not already exist.
        if(!EventLog.SourceExists("MySource"))
        {
             //An event log source should not be created and immediately used.
             //There is a latency time to enable the source, it should be created
             //prior to executing the application that uses the source.
             //Execute this sample a second time to use the new source.
            EventLog.CreateEventSource("MySource", "MyNewLog");
            Console.WriteLine("CreatedEventSource");
            Console.WriteLine("Exiting, execute the application a second time to use the source.");
            // The source is created.  Exit the application to allow it to be registered.
            return;
        }

        // Create an EventLog instance and assign its source.
        EventLog myLog = new EventLog();
        myLog.Source = "MySource";

        // Write an informational entry to the event log.    
        myLog.WriteEntry("Writing to event log.");

    }
}

In my case it was the distinction between –(En dash) and -(Hyphen) as in:

Add-Type –Path "C:\Program Files\Common Files\microsoft shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"

and:

Add-Type -Path "C:\Program Files\Common Files\microsoft shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"

Dashes, Hyphens, and Minus signs oh my!

With Git 2.23 (August 2019), that would be, using git switch -f:

git switch -f master

That avoids the confusion with git checkout (which deals with files or branches).

And that will proceeds, even if the index or the working tree differs from HEAD.
Both the index and working tree are restored to match the switching target.
If --recurse-submodules is specified, submodule content is also restored to match the switching target.
This is used to throw away local changes.

ASP.Net 4.0 added the boolean ShowHeaderWhenEmpty property.

http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.showheaderwhenempty.aspx

<asp:GridView runat="server" ID="GridView1" ShowHeaderWhenEmpty="true" AutoGenerateColumns="false">

        <asp:BoundField HeaderText="Last Name" DataField="LastName" />
    </Columns>
</asp:GridView>

Note: the headers will not appear unless DataBind() is called with something other than null.

GridView1.DataSource = New List(Of String)
GridView1.DataBind()

I think the task scheduler would be overkill (imho). There is a startup folder for win7.

C:\Users\miliu\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

Just create a shortcut for your autostart Applicaton, edit the properties of the shortcut and have it always run as administrator.

Your kids could close it of course, but if they are tech-savvy they always find a way to keep you out. I know i did when i was younger.

Good luck!

If x is just a single scalar value, you could try something like this to ensure the correct shape of the array that is being appended/concatenated to the rightmost column of a:

import numpy as np
a = np.array([[1,3,4],[1,2,3],[1,2,1]])
x = 10
b = np.hstack((a,x*np.ones((a.shape[0],1))))

returns b as:

array([[  1.,   3.,   4.,  10.],
       [  1.,   2.,   3.,  10.],
       [  1.,   2.,   1.,  10.]])

Either use a real fully qualified domain name (like dev.yourdomain.com) that pointing to 127.0.0.1 or try editing the proper hosts file (usually /etc/hosts in *nix environments).

No, this is not working. And it's not just for you, in case you spent the last hour trying to find an answer for having your embeded videos open in HD.

Question: Oh, but how do you know this is not working anymore and there is no other alternative to make embeded videos open in a different quality?

Answer: Just went to Google's official documentation regarding Youtube's player parameters and there is not a single parameter that allows you to change its quality.

Also, hd=1 doesn't work either. More info here.

Apparently Youtube analyses the width and height of the user's window (or iframe) and automatically sets the quality based on this.

UPDATE:

As of 10 of April of 2018 it still doesn't work (see my comment on the accepted answer for more details).

What I can see from comments is that it MAY work sometimes, but some others it doesn't. The accepted answer states that "it measures the network speed and the screen and player sizes". So, by that, we can understand that I CANNOT force HD as YouTube will still do whatever it wants in case of low network speed/screen resolution. From my perspective everyone saying it works just have false positives on their hands and on the occasion they tested it worked for some random reason not related to the vq parameter. If it was a valid parameter, Google would document it somewhere, and vq isn't documented anywhere.

When you use re.split and the split pattern contains capturing groups, the groups are retained in the output. If you don't want this, use a non-capturing group instead.

There seems to be a lot of misinformation about how to use this event going around (even in upvoted answers on this page).

The onbeforeunload event API is supplied by the browser for a specific purpose: The only thing you can do that's worth doing in this method is to return a string which the browser will then prompt to the user to indicate to them that action should be taken before they navigate away from the page. You CANNOT prevent them from navigating away from a page (imagine what a nightmare that would be for the end user).

Because browsers use a confirm prompt to show the user the string you returned from your event listener, you can't do anything else in the method either (like perform an ajax request).

In an application I wrote, I want to prompt the user to let them know they have unsaved changes before they leave the page. The browser prompts them with the message and, after that, it's out of my hands, the user can choose to stay or leave, but you no longer have control of the application at that point.

An example of how I use it (pseudo code):

onbeforeunload = function() {

  if(Application.hasUnsavedChanges()) {
    return 'You have unsaved changes. Please save them before leaving this page';
  }


};

If (and only if) the application has unsaved changes, then the browser prompts the user to either ignore my message (and leave the page anyway) or to not leave the page. If they choose to leave the page anyway, too bad, there's nothing you can do (nor should be able to do) about it.

Create rectangle.xml using Shape Drawable Like this put in to your Drawable Folder...

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
   <solid android:color="@android:color/transparent"/>
   <corners android:radius="12px"/> 
   <stroke  android:width="2dip" android:color="#000000"/>  
</shape>

put it in to an ImageView

<ImageView 
android:id="@+id/rectimage" 
android:layout_height="150dp" 
android:layout_width="150dp" 
android:src="@drawable/rectangle">
</ImageView>

Hope this will help you.

I have created a heap wrapper that inverts the values to create a max-heap, as well as a wrapper class for a min-heap to make the library more OOP-like. Here is the gist. There are three classes; Heap (abstract class), HeapMin, and HeapMax.

Methods:

isempty() -> bool; obvious
getroot() -> int; returns min/max
push() -> None; equivalent to heapq.heappush
pop() -> int; equivalent to heapq.heappop
view_min()/view_max() -> int; alias for getroot()
pushpop() -> int; equivalent to heapq.pushpop

I'm not sure there's a way to hide that information. No matter what you do to obfuscate or hide whatever you're doing in JavaScript, it still comes down to the fact that your browser needs to load it in order to use it. Modern browsers have web debugging/analysis tools out of the box that make extracting and viewing scripts trivial (just hit F12 in Chrome, for example).

If you're worried about exposing some kind of trade secret or algorithm, then your only recourse is to encapsulate that logic in a web service call and have your page invoke that functionality via AJAX.

• TortoiseMerge (part of ToroiseSVN) is much better than kdiff3 (I use both and can compare);
• p4merge (from Perforce) works also very well;
• Diffuse isn't so bad;
• Diffmerge from SourceGear has only one flaw in handling UTF8-files without BOM, making in unusable for this case.

var url = "https://yourURL.com";
var win = window.open(url, '_blank');
    win.opener = null;
    win.focus();

This will resolve the issue, here you don't need to use DomSanitizer. Its work for me

In a POST method, you can put an array. However, in a PUT method, you should use http_build_query to build the params like this:

curl_setopt( $ch, CURLOPT_POSTFIELDS, http_build_query( $postArr ) );

Never ever use a "background color" for your listview rows...

this will block every selector action (was my problem!)

good luck!

Long story short, EOF marker(but a different literal can be used as well) is a heredoc format that allows you to provide your input as multiline. A lot of confusion comes from how cat actually works it seems. You can use cat with >> or > as follows:

$ cat >> temp.txt
line 1
line 2

While cat can be used this way when writing manually into console, it's not convenient if I want to provide the input in a more declarative way so that it can be reused by tools and also to keep indentations, whitespaces, etc.
Heredoc allows to define your entire input as if you are not working with stdin but typing in a separate text editor. This is what Wikipedia article means by:

it is a section of a source code file that is treated as if it were a separate file.

If you need only make and friends. Try installing the command-line-tools provided by Apple. (Assuming you are not doing any iOS development.)

$query="SELECT * FROM contacts";
$result=mysql_query($query);

OK, I don't think the official snippet mentioned by galuszkak should be used everywhere, we should concern the case that some bug may be triggered during the handler such as hello_world function. Whether the response is correct or uncorrect, the Access-Control-Allow-Origin header is what we should concern. So, thing is very simple, just like bellow:

@blueprint.after_request # blueprint can also be app~~
def after_request(response):
    header = response.headers
    header['Access-Control-Allow-Origin'] = '*'
    return response

That is all~~

You can refer to following link for which features are supported in particular version of compiler. It has an exhaustive list of feature support in compiler. Looks GCC follows standard closely and implements before any other compiler.

Regarding your question you can compile using

1. g++ -std=c++11 for C++11
2. g++ -std=c++14 for C++14
3. g++ -std=c++17 for C++17
4. g++ -std=c++2a for C++20, although all features of C++20 are not yet supported refer this link for feature support list in GCC.

The list changes pretty fast, keep an eye on the list, if you are waiting for particular feature to be supported.

Let's say we need to use the class Classname that is contained in the jar file org.example.jar

And your source is in the file mysource.java Like this:

import org.example.Classname;

public class mysource {
    public static void main(String[] argv) {
    ......
   }
}

First, as you see, in your code you have to import the classes. To do that you need import org.example.Classname;

Second, when you compile the source, you have to reference the jar file.

Please note the difference in using : and ; while compiling

• If you are under a unix like operating system:

  javac -cp '.:org.example.jar' mysource.java
  

• If you are under windows:

  javac -cp .;org.example.jar mysource.java
  

After this, you obtain the bytecode file mysource.class

Now you can run this :

• If you are under a unix like operating system:

  java -cp '.:org.example.jar' mysource
  

• If you are under windows:

  java -cp .;org.example.jar mysource
  

This code worked for me (ios 7 & ios 8 for sure).

_label.numberOfLines=2;
_label.textColor=[UIColor whiteColor];

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.lineHeightMultiple=0.5;
paragraphStyle.alignment = NSTextAlignmentCenter;
paragraphStyle.lineSpacing = 1.0;

NSDictionary *nameAttributes=@{
                               NSParagraphStyleAttributeName : paragraphStyle,
                               NSBaselineOffsetAttributeName:@2.0
                               };


NSAttributedString *string=[[NSAttributedString alloc] initWithString:@"22m\nago" attributes:nameAttributes];
_label.attributedText=string;

You have to use execute immediate (dynamic sql).

DECLARE 
v_owner varchar2(40); 
v_table_name varchar2(40); 
cursor get_tables is 
select distinct table_name,user 
from user_tables 
where lower(user) = 'schema_name'; 
begin 
open get_tables; 
loop
    fetch get_tables into v_table_name,v_owner; 
    EXIT WHEN get_tables%NOTFOUND;
    execute immediate 'INSERT INTO STATS_TABLE(TABLE_NAME,SCHEMA_NAME,RECORD_COUNT,CREATED) 
    SELECT ''' || v_table_name || ''' , ''' || v_owner ||''',COUNT(*),TO_DATE(SYSDATE,''DD-MON-YY'')     FROM ' || v_table_name; 
end loop;
CLOSE get_tables; 
END; 

You can use closures to pass parameters:

iframe.document.addEventListener('click', function(event) {clic(this.id);}, false);

However, I recommend that you use a better approach to access your frame (I can only assume that you are using the DOM0 way of accessing frame windows by their name - something that is only kept around for backwards compatibility):

document.getElementById("myFrame").contentDocument.addEventListener(...);

Just to add to what Cade said, this is usually a front-end display thing and should therefore be handled there. I know that sometimes it's easier to write something 100% in SQL for things like file export or other "SQL only" solutions, but most of the times this concatenation should be handled in your display layer.

EDITED ANSWER PER DAVID'S RESPONSE:

Here's a kind of hackish way. I'm guessing there's an easier way. But you could suppress the bar labels and the plot text of the labels by saving the bar positions from barplot and do a little tweaking up and down. Here's an example with the mtcars data set:

x <- barplot(table(mtcars$cyl), xaxt="n")
labs <- paste(names(table(mtcars$cyl)), "cylinders")
text(cex=1, x=x-.25, y=-1.25, labs, xpd=TRUE, srt=45)

double m[][] declares an array of arrays, so called multidimensional array.

m[0] points to an array in the size of four, containing 0*0,1*0,2*0,3*0. Simple math shows the values are actually 0,0,0,0.

Second line is also array in the size of four, containing 0,1,2,3.

And so on...

I guess this mutiple format in you book was to show that 0*0 is row 0 column 0, 0*1 is row 0 column 1, and so on.

You can use the Linux based syntax in one of your startup scripts. Just tested this on an OS X Mountain Lion box.

eg. in your ~/.bash_profile

export TERM="xterm-color" 
export PS1='\[\e[0;33m\]\u\[\e[0m\]@\[\e[0;32m\]\h\[\e[0m\]:\[\e[0;34m\]\w\[\e[0m\]\$ '

This gives you a nice colored prompt. To add the colored ls output, you can add alias ls="ls -G".

To test, just run a source ~/.bash_profile to update your current terminal.

Side note about the colors: The colors are preceded by an escape sequence \e and defined by a color value, composed of [style;color+m] and wrapped in an escaped [] sequence. eg.

• red = \[\e[0;31m\]
• bold red (style 1) = \[\e[1;31m\]
• clear coloring = \[\e[0m\]

I always add a slightly modified color-scheme in the root's .bash_profile to make the username red, so I always see clearly if I'm logged in as root (handy to avoid mistakes if I have many terminal windows open).

In /root/.bash_profile:

PS1='\[\e[0;31m\]\u\[\e[0m\]@\[\e[0;32m\]\h\[\e[0m\]:\[\e[0;34m\]\w\[\e[0m\]\$ '

For all my SSH accounts online I make sure to put the hostname in red, to distinguish if I'm in a local or remote terminal. Just edit the .bash_profile file in your home dir on the server.. If there is no .bash_profile file on the server, you can create it and it should be sourced upon login.

If this is not working as expected for you, please read some of the comments below since I'm not using MacOS very often..

If you want to do this on a remote server, check if the ~/.bash_profile file exists. If not, simply create it and it should be automatically sourced upon your next login.

FirstOrDefault or SingleOrDefault might be useful, depending on your scenario, and whether you want to handle there being zero or more than one matches:

FirstOrDefault: Returns the first element of a sequence, or a default value if no element is found.

SingleOrDefault: Returns the only element of a sequence, or a default value if the sequence is empty; this method throws an exception if there is more than one element in the sequence

I don't know how this works in a linq 'from' query but in lambda syntax it looks like this:

var item1 = Items.FirstOrDefault(x => x.Id == 123);
var item2 = Items.SingleOrDefault(x => x.Id == 123);

If you want 'Like' search in mongo then you should go with $regex by using this query will be

db.product.find({name:{$regex:/m/i}})

for more you can read the documentation as well. https://docs.mongodb.com/manual/reference/operator/query/regex/

Good technical & logical question my dear friend. No in robots.txt file you can't go with relative URL of the sitemap; you need to go with the complete URL of the sitemap.

It's better to go with "sitemap: https://www.example.com/sitemap_index.xml"

In the above URL after the colon gives space. I also like to support Deepak.

Facebook does not allow you to change the "What's on your mind?" text box, unless of course you're developing an application for use on Facebook.

For anyone struggling with this problem in the now (Feb 2020), the following Medium post was crucial to overcoming it for us.

https://medium.com/@ttulka/spring-http-message-converters-customizing-770814eb2b55

In our case, the app uses @EnableWebMvc and would break if removed so, the section on 'The Life without Spring Boot' was critical. Here's what ended up solving this for us. It allows us to still consume and produce JSON and XML as well as format our datetime during serialization to suit the app's needs.

@Configuration
@ComponentScan("com.company.branch")
@EnableWebMvc
public class WebMvcConfig implements WebMvcConfigurer {

@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
    converters.add(0, new MappingJackson2XmlHttpMessageConverter(
                new Jackson2ObjectMapperBuilder()
                        .defaultUseWrapper(false)
                        .createXmlMapper(true)
                        .simpleDateFormat("yyyy-mm-dd'T'HH:mm:ss'Z'")
                        .build()
        ));
    converters.add(1, new MappingJackson2HttpMessageConverter(
                new Jackson2ObjectMapperBuilder()
                        .build()
        ));
    }
}

Somehow all examples, while work well, are overcomplicated:

• They use new Array(), which is an overkill (and an overhead) for a simple associative array (AKA dictionary).
• The better ones use new Object(). It works fine, but why all this extra typing?

This question is tagged "beginner", so let's make it simple.

The über-simple way to use a dictionary in JavaScript or "Why doesn't JavaScript have a special dictionary object?":

// Create an empty associative array (in JavaScript it is called ... Object)
var dict = {};   // Huh? {} is a shortcut for "new Object()"

// Add a key named fred with value 42
dict.fred = 42;  // We can do that because "fred" is a constant
                 // and conforms to id rules

// Add a key named 2bob2 with value "twins!"
dict["2bob2"] = "twins!";  // We use the subscript notation because
                           // the key is arbitrary (not id)

// Add an arbitrary dynamic key with a dynamic value
var key = ..., // Insanely complex calculations for the key
    val = ...; // Insanely complex calculations for the value
dict[key] = val;

// Read value of "fred"
val = dict.fred;

// Read value of 2bob2
val = dict["2bob2"];

// Read value of our cool secret key
val = dict[key];

Now let's change values:

// Change the value of fred
dict.fred = "astra";
// The assignment creates and/or replaces key-value pairs

// Change the value of 2bob2
dict["2bob2"] = [1, 2, 3];  // Any legal value can be used

// Change value of our secret key
dict[key] = undefined;
// Contrary to popular beliefs, assigning "undefined" does not remove the key

// Go over all keys and values in our dictionary
for (key in dict) {
  // A for-in loop goes over all properties, including inherited properties
  // Let's use only our own properties
  if (dict.hasOwnProperty(key)) {
    console.log("key = " + key + ", value = " + dict[key]);
  }
}

Deleting values is easy too:

// Let's delete fred
delete dict.fred;
// fred is removed, but the rest is still intact

// Let's delete 2bob2
delete dict["2bob2"];

// Let's delete our secret key
delete dict[key];

// Now dict is empty

// Let's replace it, recreating all original data
dict = {
  fred:    42,
  "2bob2": "twins!"
  // We can't add the original secret key because it was dynamic, but
  // we can only add static keys
  // ...
  // oh well
  temp1:   val
};
// Let's rename temp1 into our secret key:
if (key != "temp1") {
  dict[key] = dict.temp1; // Copy the value
  delete dict.temp1;      // Kill the old key
} else {
  // Do nothing; we are good ;-)
}

When a script is loaded, any parameters that are passed are automatically loaded into a special variables $args. You can reference that in your script without first declaring it.

As an example, create a file called test.ps1 and simply have the variable $args on a line by itself. Invoking the script like this, generates the following output:

PowerShell.exe -File test.ps1 a b c "Easy as one, two, three"
a
b
c
Easy as one, two, three

As a general recommendation, when invoking a script by calling PowerShell directly I would suggest using the -File option rather than implicitly invoking it with the & - it can make the command line a bit cleaner, particularly if you need to deal with nested quotes.
