I'm sure there must be a standard library function for this, but it was fun to try to write it myself using recursion so here's what I came up with:

def intToStringWithCommas(x):
    if type(x) is not int and type(x) is not long:
        raise TypeError("Not an integer!")
    if x < 0:
        return '-' + intToStringWithCommas(-x)
    elif x < 1000:
        return str(x)
    else:
        return intToStringWithCommas(x / 1000) + ',' + '%03d' % (x % 1000)

Having said that, if someone else does find a standard way to do it, you should use that instead.

Open a new connection when the Node.js application starts, and reuse the existing db connection object:

/server.js

import express from 'express';
import Promise from 'bluebird';
import logger from 'winston';
import { MongoClient } from 'mongodb';
import config from './config';
import usersRestApi from './api/users';

const app = express();

app.use('/api/users', usersRestApi);

app.get('/', (req, res) => {
  res.send('Hello World');
});

// Create a MongoDB connection pool and start the application
// after the database connection is ready
MongoClient.connect(config.database.url, { promiseLibrary: Promise }, (err, db) => {
  if (err) {
    logger.warn(`Failed to connect to the database. ${err.stack}`);
  }
  app.locals.db = db;
  app.listen(config.port, () => {
    logger.info(`Node.js app is listening at http://localhost:${config.port}`);
  });
});

/api/users.js

import { Router } from 'express';
import { ObjectID } from 'mongodb';

const router = new Router();

router.get('/:id', async (req, res, next) => {
  try {
    const db = req.app.locals.db;
    const id = new ObjectID(req.params.id);
    const user = await db.collection('user').findOne({ _id: id }, {
      email: 1,
      firstName: 1,
      lastName: 1
    });

    if (user) {
      user.id = req.params.id;
      res.send(user);
    } else {
      res.sendStatus(404);
    }
  } catch (err) {
    next(err);
  }
});

export default router;

Add android:layout_centerInParent="true" to element which you want to center in the RelativeLayout

Change position:absolute to position:fixed;.

Example can be found in this jsFiddle.

Put this on an event

$(function(){
    $('.package').click(function(){
       var content = $('.container').html();
       $(this).html(content);
    });
});

I have used a method to test if any specific key is pressed by storing the currently pressed key codes in an array:

var keysPressed = [],
    shiftCode = 16;

$(document).on("keyup keydown", function(e) {
    switch(e.type) {
        case "keydown" :
            keysPressed.push(e.keyCode);
            break;
        case "keyup" :
            var idx = keysPressed.indexOf(e.keyCode);
            if (idx >= 0)
                keysPressed.splice(idx, 1);
            break;
    }
});

$("a.shifty").on("click", function(e) {
    e.preventDefault();
    console.log("Shift Pressed: " + (isKeyPressed(shiftCode) ? "true" : "false"));
});

function isKeyPressed(code) {
    return keysPressed.indexOf(code) >= 0;
}

Here is the jsfiddle

Yes Go does accept first-class functions.

See the article "First Class Functions in Go" for useful links.

Try this:

$NameRegex = "chalmw-dm"  
$NameR = "$($NameRegex)*"
Get-ADComputer -Filter {name -like $NameR -and Enabled -eq $True}

Add your php folder path to the System PATH and everything should work fine. It will also fix some other extensions that are broken.

You can try like this:

SELECT PARSENAME('$'+ Convert(varchar,Convert(money,@MoneyValue),1),2)

Define myurl command:

\def\myurl{\hfil\penalty 100 \hfilneg \hbox}

I don't want to cause line overflows, 
I'd just rather LaTeX insert linebreaks before 
\myurl{\tt http://stackoverflow.com/questions/1012799/} 
regions rather than inside them.

I know this is a old question but i think i must provide my answer to it because my problem was not solved by others.

first of all : i was dynamically adding fragments using fragmentTransactions. Second: my fragments were modified using AsyncTasks (DB queries on a server). Third: my fragment was not instantiated at activity start Fourth: i used a custom fragment instantiation "create or load it" in order to get the fragment variable. Fourth: activity was recreated because of orientation change

The problem was that i wanted to "remove" the fragment because of the query answer, but the fragment was incorrectly created just before. I don't know why, probably because of the "commit" be done later, the fragment was not added yet when it was time to remove it. Therefore getActivity() was returning null.

Solution : 1)I had to check that i was correctly trying to find the first instance of the fragment before creating a new one 2)I had to put serRetainInstance(true) on that fragment in order to keep it through orientation change (no backstack needed therefore no problem) 3)Instead of "recreating or getting old fragment" just before "remove it", I directly put the fragment at activity start. Instantiating it at activity start instead of "loading" (or instantiating) the fragment variable before removing it prevented getActivity problems.

Why was the problem: As someone already specified: If you start with a byte[] and it does not in fact contain text data, there is no "proper conversion". Strings are for text, byte[] is for binary data, and the only really sensible thing to do is to avoid converting between them unless you absolutely have to.

I was observing this problem when I was trying to create byte[] from a pdf file and then converting it to String and then taking the String as input and converting back to file.

So make sure your encoding and decoding logic is same as I did. I explicitly encoded the byte[] to Base64 and decoded it to create the file again.

Use-case: Due to some limitation I was trying to sent byte[] in request(POST) and the process was as follows:

PDF File >> Base64.encodeBase64(byte[]) >> String >> Send in request(POST) >> receive String >> Base64.decodeBase64(byte[]) >> create binary

Try this and this worked for me..

File file = new File("filePath");

        byte[] byteArray = new byte[(int) file.length()];

        try {
            FileInputStream fileInputStream = new FileInputStream(file);
            fileInputStream.read(byteArray);

            String byteArrayStr= new String(Base64.encodeBase64(byteArray));

            FileOutputStream fos = new FileOutputStream("newFilePath");
            fos.write(Base64.decodeBase64(byteArrayStr.getBytes()));
            fos.close();
        } 
        catch (FileNotFoundException e) {
            System.out.println("File Not Found.");
            e.printStackTrace();
        }
        catch (IOException e1) {
            System.out.println("Error Reading The File.");
            e1.printStackTrace();
        }

Extending your requirements a bit and assuming you do not care about the order of lines and want to get them grouped under categories, the following solution may work for you:

>>> fname = "lines.txt"
>>> from collections import defaultdict
>>> dct = defaultdict(list)
>>> with open(fname) as f:
...     for line in f:
...         text, cat = line.rstrip("\n").split(",", 1)
...         dct[cat].append(text)
...
>>> dct
defaultdict(<type 'list'>, {' CatA': ['This is the first line', 'This is the another line'], ' CatC': ['This is the third line'], ' CatB': ['This is the second line', 'This is the last line']})

This way you get all relevant lines available in the dictionary under key being the category.

I had to use same modal for different link clicks. I just replaced the html content with empty "" of the modal in hidden callback.

This should work

SELECT EXTRACTVALUE(column_name, '/DCResponse/ContextData/Decision') FROM traptabclob;

I have assumed the ** were just for highlighting?

E:>move "blogger code.txt" d:/"blogger code.txt"

    1 file(s) moved.

"blogger code.txt" is a file name

The file move from E: drive to D: drive

Set the GET query parameters as managed properties in faces-config.xml so that you don't need to gather them manually:

<managed-bean>
    <managed-bean-name>forward</managed-bean-name>
    <managed-bean-class>com.example.ForwardBean</managed-bean-class>
    <managed-bean-scope>request</managed-bean-scope>
    <managed-property>
        <property-name>action</property-name>
        <value>#{param.action}</value>
    </managed-property>
    <managed-property>
        <property-name>actionParam</property-name>
        <value>#{param.actionParam}</value>
    </managed-property>
</managed-bean>

This way the request forward.jsf?action=outcome1&actionParam=123 will let JSF set the action and actionParam parameters as action and actionParam properties of the ForwardBean.

Create a small view forward.xhtml (so small that it fits in default response buffer (often 2KB) so that it can be resetted by the navigationhandler, otherwise you've to increase the response buffer in the servletcontainer's configuration), which invokes a bean method on beforePhase of the f:view:

<!DOCTYPE html>
<html xmlns:f="http://java.sun.com/jsf/core">
    <f:view beforePhase="#{forward.navigate}" />
</html>

The ForwardBean can look like this:

public class ForwardBean {
    private String action;
    private String actionParam;

    public void navigate(PhaseEvent event) {
        FacesContext facesContext = FacesContext.getCurrentInstance();
        String outcome = action; // Do your thing?
        facesContext.getApplication().getNavigationHandler().handleNavigation(facesContext, null, outcome);
    }

    // Add/generate the usual boilerplate.
}

The navigation-rule speaks for itself (note the <redirect /> entries which would do ExternalContext#redirect() instead of ExternalContext#dispatch() under the covers):

<navigation-rule>
    <navigation-case>
        <from-outcome>outcome1</from-outcome>
        <to-view-id>/outcome1.xhtml</to-view-id>
        <redirect />
    </navigation-case>
    <navigation-case>
        <from-outcome>outcome2</from-outcome>
        <to-view-id>/outcome2.xhtml</to-view-id>
        <redirect />
    </navigation-case>
</navigation-rule>

An alternative is to use forward.xhtml as

<!DOCTYPE html>
<html>#{forward}</html>

and update the navigate() method to be invoked on @PostConstruct (which will be invoked after bean's construction and all managed property setting):

@PostConstruct
public void navigate() {
    // ...
}    

It has the same effect, however the view side is not really self-documenting. All it basically does is printing ForwardBean#toString() (and hereby implicitly constructing the bean if not present yet).

Note for the JSF2 users, there is a cleaner way of passing parameters with <f:viewParam> and more robust way of handling the redirect/navigation by <f:event type="preRenderView">. See also among others:

• Hit a bean method and redirect on a GET request
• Is there any easy way to preprocess and redirect GET requests?

I don't think this is possible in Python, since what you're actually trying to do probably gets expanded to something like this:

num1 = 20 if someBoolValue else num1

If you exclude else num1, you'll receive a syntax error since I'm quite sure that the assignment must actually return something.

As others have already mentioned, you could do this, but it's bad because you'll probably just end up confusing yourself when reading that piece of code the next time:

if someBoolValue: num1=20

I'm not a big fan of the num1 = someBoolValue and 20 or num1 for the exact same reason. I have to actually think twice on what that line is doing.

The best way to actually achieve what you want to do is the original version:

if someBoolValue:
    num1 = 20

The reason that's the best verison is because it's very obvious what you want to do, and you won't confuse yourself, or whoever else is going to come in contact with that code later.

Also, as a side note, num1 = 20 if someBoolValue is valid Ruby code, because Ruby works a bit differently.

If using scala, try priv + tab

Deleting and Recreating a project with same name is tricky. If you try to follow above suggested steps and try to create a project with same name as the one you just deleted, you will run into error like

'C:/xxxxxx/pom.xml' already exists in VFS

Here is what I found would work.

1. Remove module
2. File -> Invalidate Cache (at this point the Intelli IDEA wants to restart)
3. Close project
4. Delete the folder form system explorer.
5. Now you can create a project with same name as before.

well check out the eclipse distro easyeclipse at EasyEclipse. it has Visual editor project already added as a plugin, so no hassles of eclipse version compatibility.Plus the eclipse help section has a tutorial on VE.

For my application i made a helper function:

function message( $message , $status = 'success', $redirectPath = null )
{
     $redirectPath = $redirectPath == null ? back() : redirect( $redirectPath );

     return $redirectPath->with([
         'message'   =>  $message,
         'status'    =>  $status,
    ]);
}

message layout, main.layouts.message:

@if($status)
   <div class="center-block affix alert alert-{{$status}}">
     <i class="fa fa-{{ $status == 'success' ? 'check' : $status}}"></i>
     <span>
        {{ $message }}
     </span>
   </div>
@endif

and import every where to show message:

@include('main.layouts.message', [
    'status'    =>  session('status'),
    'message'   =>  session('message'),
])

For the TL;DR, here are 2 cents and a simpler version for your questions:

1. WebSockets provides these benefits over HTTP:

   • Persistent stateful connection for the duration of the connection
   • Low latency: near-real-time communication between server/client due to no overhead of reestablishing connections for each request as HTTP requires.
   • Full duplex: both server and client can send/receive simultaneously

2. WebSocket and HTTP protocol have been designed to solve different problems, I.E. WebSocket was designed to improve bi-directional communication whereas HTTP was designed to be stateless, distributed using a request/response model. Other than sharing the ports for legacy reasons (firewall/proxy penetration), there isn't much common ground to combine them into one protocol.

Sub GetUniqueAndCount()

    Dim d As Object, c As Range, k, tmp As String

    Set d = CreateObject("scripting.dictionary")
    For Each c In Selection
        tmp = Trim(c.Value)
        If Len(tmp) > 0 Then d(tmp) = d(tmp) + 1
    Next c

    For Each k In d.keys
        Debug.Print k, d(k)
    Next k

This is exactly what ajax is for. See here:

http://api.jquery.com/load/

Basically, you ajax/test.php and put the returned HTML code to the element which has the result id.

$('#result').load('ajax/test.php');

Of course, you will need to put the functionality which takes time to a new php file (or call the old one with a GET parameter which will activate that functionality only).

We are using DBS of 50 GB+ on our platform. no complains works great. Make sure you are doing everything right! Are you using predefined statements ? *SQLITE 3.7.3

1. Transactions
2. Pre made statements

3. Apply these settings (right after you create the DB)

   PRAGMA main.page_size = 4096;
   PRAGMA main.cache_size=10000;
   PRAGMA main.locking_mode=EXCLUSIVE;
   PRAGMA main.synchronous=NORMAL;
   PRAGMA main.journal_mode=WAL;
   PRAGMA main.cache_size=5000;
   

Hope this will help others, works great here

If you want to change recent workspace manually in a configurationfile org.eclipse.ui.ide.prefs exists in

eclipse > configuration > .settings > org.eclipse.ui.ide.prefs

open this file in an editor find RECENT_WORKSPACES in line #2 and in this line you can see recent workspaces and can change or even remove them.

If you have a SharedPreferenceActivity by which you have saved your values

SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
String imgSett = prefs.getString(keyChannel, "");

if the value is saved in a SharedPreference in an Activity then this is the correct way to saving it.

SharedPreferences shared = getSharedPreferences(PREF_NAME, MODE_PRIVATE);
SharedPreferences.Editor editor = shared.edit();
editor.putString(keyChannel, email);
editor.commit();// commit is important here.

and this is how you can retrieve the values.

SharedPreferences shared = getSharedPreferences(PREF_NAME, MODE_PRIVATE);
String channel = (shared.getString(keyChannel, ""));

Also be aware that you can do so in a non-Activity class too but the only condition is that you need to pass the context of the Activity. use this context in to get the SharedPreferences.

mContext.getSharedPreferences(PREF_NAME, MODE_PRIVATE);

Every Ansible task when run can save its results into a variable. To do this, you have to specify which variable to save the results into. Do this with the register parameter, independently of the module used.

Once you save the results to a variable you can use it later in any of the subsequent tasks. So for example if you want to get the standard output of a specific task you can write the following:

---
- hosts: localhost
  tasks:
    - shell: ls
      register: shell_result

    - debug:
        var: shell_result.stdout_lines

Here register tells ansible to save the response of the module into the shell_result variable, and then we use the debug module to print the variable out.

An example run would look like the this:

PLAY [localhost] ***************************************************************

TASK [command] *****************************************************************
changed: [localhost]

TASK [debug] *******************************************************************
ok: [localhost] => {
    "shell_result.stdout_lines": [
        "play.yml"
    ]
}

Responses can contain multiple fields. stdout_lines is one of the default fields you can expect from a module's response.

Not all fields are available from all modules, for example for a module which doesn't return anything to the standard out you wouldn't expect anything in the stdout or stdout_lines values, however the msg field might be filled in this case. Also there are some modules where you might find something in a non-standard variable, for these you can try to consult the module's documentation for these non-standard return values.

Alternatively you can increase the verbosity level of ansible-playbook. You can choose between different verbosity levels: -v, -vvv and -vvvv. For example when running the playbook with verbosity (-vvv) you get this:

PLAY [localhost] ***************************************************************

TASK [command] *****************************************************************
(...)
changed: [localhost] => {
    "changed": true,
    "cmd": "ls",
    "delta": "0:00:00.007621",
    "end": "2017-02-17 23:04:41.912570",
    "invocation": {
        "module_args": {
            "_raw_params": "ls",
            "_uses_shell": true,
            "chdir": null,
            "creates": null,
            "executable": null,
            "removes": null,
            "warn": true
        },
        "module_name": "command"
    },
    "rc": 0,
    "start": "2017-02-17 23:04:41.904949",
    "stderr": "",
    "stdout": "play.retry\nplay.yml",
    "stdout_lines": [
        "play.retry",
        "play.yml"
    ],
    "warnings": []
}

As you can see this will print out the response of each of the modules, and all of the fields available. You can see that the stdout_lines is available, and its contents are what we expect.

To answer your main question about the jenkins_script module, if you check its documentation, you can see that it returns the output in the output field, so you might want to try the following:

tasks:
  - jenkins_script:
      script: (...)
    register: jenkins_result

  - debug:
      var: jenkins_result.output

long n = long.Parse(date.ToString("yyyyMMddHHmmss"));

I think this is a simple code in java which will show the string value in CSV after compile this code.

public class CsvWriter {

    public static void main(String args[]) {
        // File input path
        System.out.println("Starting....");
        File file = new File("/home/Desktop/test/output.csv");
        try {
            FileWriter output = new FileWriter(file);
            CSVWriter write = new CSVWriter(output);

            // Header column value
            String[] header = { "ID", "Name", "Address", "Phone Number" };
            write.writeNext(header);
            // Value
            String[] data1 = { "1", "First Name", "Address1", "12345" };
            write.writeNext(data1);
            String[] data2 = { "2", "Second Name", "Address2", "123456" };
            write.writeNext(data2);
            String[] data3 = { "3", "Third Name", "Address3", "1234567" };
            write.writeNext(data3);
            write.close();
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();

        }

        System.out.println("End.");

    }
}

1. Use post when you don't know how the new resource URI would look like (you create new user, application would assign the new user it's id), PUT for updating or creating resources that you know how are they going to be represented (example: PUT /myfiles/thisismynewfile.txt)
2. return the error description in message body
3. You can use HTTP authentication (if it's enough) Web services should be stateles

Use Google CDN for fast loading:

Simple, comfortable and understandable with Validator

class CustomerController extends Controller
{
    public function register(Request $request)
    {

        $validator = Validator::make($request->all(), [
            'name' => 'required|string|max:255',
            'email' => 'required|string|email|max:255|unique:customers',
            'phone' => 'required|string|max:255|unique:customers',
            'password' => 'required|string|min:6|confirmed',
        ]);

        if ($validator->fails()) {
            return response(['errors' => $validator->errors()->all()], 422);
        }

You can use include=FALSE to exclude everything in a chunk.

```{r include=FALSE}
source("C:/Rscripts/source.R")
```

If you only want to suppress messages, use message=FALSE instead:

```{r message=FALSE}
source("C:/Rscripts/source.R")
```

As with the previous solutions cookies are a good method, be aware that they identify browsers though. If I visited a website in Firefox and then in Internet Explorer cookies would be stored for both attempts seperately. Some users also disable cookies (but more people disable JavaScript).

Another method to consider would be I.P. and hostname identification (be aware these can vary for dial-up/non-static IP users, AOL also uses blanket IPs). However since this only identifies networks this might not work as well as cookies.

Definitely this gives good solution,

ResultSet rs = stmt.execute("SQL QUERY");
// With the above statement you will not have a null ResultSet 'rs'.
// In case, if any exception occurs then next line of code won't execute.
// So, no problem if I won't check rs as null.

if (rs.next()) {
    do {
      // Logic to retrieve the data from the resultset.
      // eg: rs.getString("abc");
    } while(rs.next());
} else {
    // No data
}

You can react to new file activity with FileSystemWatcher.

Not really an answer to your question but I had a requirement to sort a List of maps by its values' properties, this will work in your case too:

List<Map<String, Object>> sortedListOfMaps = someListOfMaps.sorted(Comparator.comparing(map -> ((String) map.get("someKey")))).collect(Collectors.toList()))

In C/C++ sizeof. always gives the number of bytes in the entire object, and arrays are treated as one object. Note: sizeof a pointer--to the first element of an array or to a single object--gives the size of the pointer, not the object(s) pointed to. Either way, sizeof does not give the number of elements in the array (its length). To get the length, you need to divide by the size of each element. eg.,

for( unsigned int a = 0; a < sizeof(texts)/sizeof(texts[0]); a = a + 1 )

As for doing it the C++11 way, the best way to do it is probably

for(const string &text : texts)
    cout << "value of text: " << text << endl;

This lets the compiler figure out how many iterations you need.

EDIT: as others have pointed out, std::array is preferred in C++11 over raw arrays; however, none of the other answers addressed why sizeof is failing the way it is, so I still think this is the better answer.

Using sup on the letter "o" and a capital "C"

<sup>o</sup>C

Should work in all browsers and IE6+

You can use either of these functions:

// This should work in node.js and other ES5 compliant implementations.
function isEmptyObject(obj) {
  return !Object.keys(obj).length;
}

// This should work both there and elsewhere.
function isEmptyObject(obj) {
  for (var key in obj) {
    if (Object.prototype.hasOwnProperty.call(obj, key)) {
      return false;
    }
  }
  return true;
}

Example usage:

if (isEmptyObject(query)) {
  // There are no queries.
} else {
  // There is at least one query,
  // or at least the query object is not empty.
}

B+Trees are much easier and higher performing to do a full scan, as in look at every piece of data that the tree indexes, since the terminal nodes form a linked list. To do a full scan with a B-Tree you need to do a full tree traversal to find all the data.

B-Trees on the other hand can be faster when you do a seek (looking for a specific piece of data by key) especially when the tree resides in RAM or other non-block storage. Since you can elevate commonly used nodes in the tree there are less comparisons required to get to the data.

If, at some point, you only need to export a single result set, just right click "on the data" (any column of any row) there you will find an export option. The wizard exports the complete result set regardless of what you selected

You can get around this limit with the deprecated syntax: ORDER BY 1 DESC

This syntax is not deprecated at all, it's E121-03 from SQL99.

public static boolean isDirectory(String path) {
    return path !=null && new File(path).isDirectory();
}

To answer the question directly.

I wrote a mixin for some syntactic sugar ;)
Maybe someone likes this way of writing if-then-else better than using guards

depends on Less 1.7.0

https://github.com/pixelass/more-or-less/blob/master/less/fn/_if.less

Usage:

.if(isnumber(2), {
    .-then(){
        log {
            isnumber: true;
        }
    }
    .-else(){
        log {
            isnumber: false;
        }
    }
});

.if(lightness(#fff) gt (20% * 2), {
    .-then(){
        log {
            is-light: true;
        }
    }
});

using on example from above

.if(@debug, {
    .-then(){
        header {
            background-color: yellow;
            #title {
                background-color: orange;
            }
        }
        article {
            background-color: red;
        }
    }
});

Simply :

   <label>@Html.RadioButton("ABC", True)Yes</label>
   <label>@Html.RadioButton("ABC", False)No</label>

But you should always use strongly typed model as suggested by cacho.

Can also invoke oShell.Exec in order to be able to read STDIN/STDOUT/STDERR responses. Perfect for error checking which it seems you're doing with your sanity .BAT.

Here are quite a few ways to add dictionaries.

You can use Python3's dictionary unpacking feature.

ndic = {**dic0, **dic1}

Or create a new dict by adding both items.

ndic = dict(dic0.items() + dic1.items())

If your ok to modify dic0

dic0.update(dic1)

If your NOT ok to modify dic0

ndic = dic0.copy()
ndic.update(dic1)

If all the keys in one dict are ensured to be strings (dic1 in this case, of course args can be swapped)

ndic = dict(dic0, **dic1)

In some cases it may be handy to use dict comprehensions (Python 2.7 or newer),
Especially if you want to filter out or transform some keys/values at the same time.

ndic = {k: v for d in (dic0, dic1) for k, v in d.items()}

The following code will split a string with an arbitrary number of substrings:

@echo off
setlocal ENABLEDELAYEDEXPANSION

REM Set a string with an arbitrary number of substrings separated by semi colons
set teststring=The;rain;in;spain

REM Do something with each substring
:stringLOOP
    REM Stop when the string is empty
    if "!teststring!" EQU "" goto END

    for /f "delims=;" %%a in ("!teststring!") do set substring=%%a

        REM Do something with the substring - 
        REM we just echo it for the purposes of demo
        echo !substring!

REM Now strip off the leading substring
:striploop
    set stripchar=!teststring:~0,1!
    set teststring=!teststring:~1!

    if "!teststring!" EQU "" goto stringloop

    if "!stripchar!" NEQ ";" goto striploop

    goto stringloop
)

:END
endlocal

This should do the trick:

public static int[] addPos(int[] a, int pos, int num) {
    int[] result = new int[a.length];
    for(int i = 0; i < pos; i++)
        result[i] = a[i];
    result[pos] = num;
    for(int i = pos + 1; i < a.length; i++)
        result[i] = a[i - 1];
    return result;
}

Where a is the original array, pos is the position of insertion, and num is the number to be inserted.

shape is a tuple that gives you an indication of the number of dimensions in the array. So in your case, since the index value of Y.shape[0] is 0, your are working along the first dimension of your array.

From http://www.scipy.org/Tentative_NumPy_Tutorial#head-62ef2d3c0a5b4b7d6fdc48e4a60fe48b1ffe5006

 An array has a shape given by the number of elements along each axis:
 >>> a = floor(10*random.random((3,4)))

 >>> a
 array([[ 7.,  5.,  9.,  3.],
        [ 7.,  2.,  7.,  8.],
        [ 6.,  8.,  3.,  2.]])

 >>> a.shape
 (3, 4)

and http://www.scipy.org/Numpy_Example_List#shape has some more examples.

Tumblr has a public API that provides JSON. You can get a dump of posts using a simple url like http://puppygifs.tumblr.com/api/read/json.

For me, it said Module did not found and not worked. Finally, I found this solution and worked.

<img v-bind:src="require('@' + baseUrl + 'path/path' + obj.key +'.png')"/>

Needed to add '@' at the beginning of the local path.

Use os.path.join to combine the path to the Documents directory with the completeName (filename?) supplied by the user.

import os
with open(os.path.join('/path/to/Documents',completeName), "w") as file1:
    toFile = raw_input("Write what you want into the field")
    file1.write(toFile)

If you want the Documents directory to be relative to the user's home directory, you could use something like:

os.path.join(os.path.expanduser('~'),'Documents',completeName)

Others have proposed using os.path.abspath. Note that os.path.abspath does not resolve '~' to the user's home directory:

In [10]: cd /tmp
/tmp

In [11]: os.path.abspath("~")
Out[11]: '/tmp/~'

I found it. Perl has multi-line comments:

#!/usr/bin/perl

use strict;

use warnings;

=for comment

Karan Bhandari's answer is good, but the AccountController added in a project is very likely a Mvc.Controller. To convert his answer for use in an ApiController change HttpContext.Current.GetOwinContext() to Request.GetOwinContext() and make sure you have added the following 2 using statements:

using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.Owin;

You could keep it simple and use the native color translator:

Color red = ColorTranslator.FromHtml("#FF0000");
string redHex = ColorTranslator.ToHtml(red);

Then break the three color pairs into integer form:

int value = int.Parse(hexValue, System.Globalization.NumberStyles.HexNumber);

My implementation, works great in older ES versions:

sortObject = function(data) {
    var keys = Object.keys(data);
    var result = {};

    keys.sort();

    for(var i = 0; i < keys.length; i++) {
        var key = keys[i];

        result[key] = data[key];
    }

    return result;
};

Use jQuery's IsNumeric method.

http://api.jquery.com/jQuery.isNumeric/

if ($.isNumeric(id)) {
   //it's numeric
}

CORRECTION: that would not ensure an integer. This would:

if ( (id+"").match(/^\d+$/) ) {
   //it's all digits
}

That, of course, doesn't use jQuery, but I assume jQuery isn't actually mandatory as long as the solution works

VSCode will never refresh the file if you have changes in that file that are not saved to disk. However, if the file is open and does not have changes, it will replace with the changes on disk, that is true.

There is currently no way to disable this behaviour.

Use etree.indent and etree.tostring

import lxml.etree as etree

root = etree.fromstring('<html><head></head><body><h1>Welcome</h1></body></html>')
etree.indent(root, space="  ")
xml_string = etree.tostring(root, pretty_print=True).decode()
print(xml_string)

output

<html>
  <head/>
  <body>
    <h1>Welcome</h1>
  </body>
</html>

Removing namespaces and prefixes

import lxml.etree as etree


def dump_xml(element):
    for item in element.getiterator():
        item.tag = etree.QName(item).localname

    etree.cleanup_namespaces(element)
    etree.indent(element, space="  ")
    result = etree.tostring(element, pretty_print=True).decode()
    return result


root = etree.fromstring('<cs:document xmlns:cs="http://blabla.com"><name>hello world</name></cs:document>')
xml_string = dump_xml(root)
print(xml_string)

output

<document>
  <name>hello world</name>
</document>

 $.ajax({
            type: "POST",
            data: {data:the_id},
            url: "http://localhost/test/index.php/data/count_votes",
            success: function(data){
               //data will contain the vote count echoed by the controller i.e.  
                 "yourVoteCount"
              //then append the result where ever you want like
              $("span#votes_number").html(data); //data will be containing the vote count which you have echoed from the controller

                }
            });

in the controller

$data = $_POST['data'];  //$data will contain the_id
//do some processing
echo "yourVoteCount";

Clarification

i think you are confusing

{data:the_id}

with

success:function(data){

both the data are different for your own clarity sake you can modify it as

success:function(vote_count){
$(span#someId).html(vote_count);

Try:

echo "`date` User `whoami` started the script."$'\n' >> output.log

or just:

echo $'\n' >> output.log

Maybe you could do

SELECT * FROM table LIMIT 10000 OFFSET FLOOR(RAND() * 190000)

Eg: Add data:-

   Bundle bundle = new Bundle();
   bundle.putString("latitude", latitude);
   bundle.putString("longitude", longitude);
   bundle.putString("board_id", board_id);
   MapFragment mapFragment = new MapFragment();
   mapFragment.setArguments(bundle);

Eg: Get data :-

String latitude =  getArguments().getString("latitude")

What you're looking at is an expression-bodied member not a lambda expression.

When the compiler encounters an expression-bodied property member, it essentially converts it to a getter like this:

public int MaxHealth
{
    get
    {
        return Memory[Address].IsValid ? Memory[Address].Read<int>(Offs.Life.MaxHp) : 0;
    }
}

(You can verify this for yourself by pumping the code into a tool called TryRoslyn.)

Expression-bodied members - like most C# 6 features - are just syntactic sugar. This means that they don’t provide functionality that couldn't otherwise be achieved through existing features. Instead, these new features allow a more expressive and succinct syntax to be used

As you can see, expression-bodied members have a handful of shortcuts that make property members more compact:

• There is no need to use a return statement because the compiler can infer that you want to return the result of the expression
• There is no need to create a statement block because the body is only one expression
• There is no need to use the get keyword because it is implied by the use of the expression-bodied member syntax.

I have made the final point bold because it is relevant to your actual question, which I will answer now.

The difference between...

// expression-bodied member property
public int MaxHealth => x ? y:z;

And...

// field with field initializer
public int MaxHealth = x ? y:z;

Is the same as the difference between...

public int MaxHealth
{
    get
    {
        return x ? y:z;
    }
}

And...

public int MaxHealth = x ? y:z;

Which - if you understand properties - should be obvious.

Just to be clear, though: the first listing is a property with a getter under the hood that will be called each time you access it. The second listing is is a field with a field initializer, whose expression is only evaluated once, when the type is instantiated.

This difference in syntax is actually quite subtle and can lead to a "gotcha" which is described by Bill Wagner in a post entitled "A C# 6 gotcha: Initialization vs. Expression Bodied Members".

While expression-bodied members are lambda expression-like, they are not lambda expressions. The fundamental difference is that a lambda expression results in either a delegate instance or an expression tree. Expression-bodied members are just a directive to the compiler to generate a property behind the scenes. The similarity (more or less) starts and end with the arrow (=>).

I'll also add that expression-bodied members are not limited to property members. They work on all these members:

• Properties
• Indexers
• Methods
• Operators

Added in C# 7.0

• Constructors
• Finalizers

However, they do not work on these members:

• Nested Types
• Events
• Fields

Max. capacity is 2 gigabytes of space - so you're looking at just over 1 billion 2-byte characters that will fit into a NVARCHAR(MAX) field.

Using the other answer's more detailed numbers, you should be able to store

(2 ^ 31 - 1 - 2) / 2 = 1'073'741'822 double-byte characters

1 billion, 73 million, 741 thousand and 822 characters to be precise

in your NVARCHAR(MAX) column (unfortunately, that last half character is wasted...)

Update: as @MartinMulder pointed out: any variable length character column also has a 2 byte overhead for storing the actual length - so I needed to subtract two more bytes from the 2 ^ 31 - 1 length I had previously stipulated - thus you can store 1 Unicode character less than I had claimed before.

WMI queries are slow, so try to Select only the desired members instead of using Select *.

The following query takes 3.4s:

foreach (var item in new System.Management.ManagementObjectSearcher("Select * from Win32_Processor").Get())

While this one takes 0.122s:

foreach (var item in new System.Management.ManagementObjectSearcher("Select NumberOfCores from Win32_Processor").Get())

Why not use the built in events?

$('#checkbox').click(function(e){
    if(e.target.checked) {
     // code to run if checked
        console.log('Checked');

     } else {

     //code to run if unchecked
        console.log('Unchecked');
     }
});

Beware float: left…

…there are many ways to align elements side-by-side.

Below are the most common ways to achieve two elements side-by-side…

Demo: View/edit all the below examples on Codepen

Basic styles for all examples below…

Some basic css styles for parent and child elements in these examples:

.parent {
  background: mediumpurple;
  padding: 1rem;
}
.child {
  border: 1px solid indigo;
  padding: 1rem;
}

Using the float solution my have unintended affect on other elements. (Hint: You may need to use a clearfix.)

html

<div class='parent'>
  <div class='child float-left-child'>A</div>
  <div class='child float-left-child'>B</div>
</div>

css

.float-left-child {
  float: left;
}

html

<div class='parent'>
  <div class='child inline-block-child'>A</div>
  <div class='child inline-block-child'>B</div>
</div>

css

.inline-block-child {
  display: inline-block;
}

Note: the space between these two child elements can be removed, by removing the space between the div tags:

html

<div class='parent'>
  <div class='child inline-block-child'>A</div><div class='child inline-block-child'>B</div>
</div>

css

.inline-block-child {
  display: inline-block;
}

html

<div class='parent flex-parent'>
  <div class='child flex-child'>A</div>
  <div class='child flex-child'>B</div>
</div>

css

.flex-parent {
  display: flex;
}
.flex-child {
  flex: 1;
}

html

<div class='parent inline-flex-parent'>
  <div class='child'>A</div>
  <div class='child'>B</div>
</div>

css

.inline-flex-parent {
  display: inline-flex;
}

html

<div class='parent grid-parent'>
  <div class='child'>A</div>
  <div class='child'>B</div>
</div>

css

.grid-parent {
  display: grid;
  grid-template-columns: 1fr 1fr
}

The best option is to use jax-ws-catalog.xml

When you compile the local WSDL file , override the WSDL location and set it to something like

http://localhost/wsdl/SOAService.wsdl

Don't worry this is only a URI and not a URL , meaning you don't have to have the WSDL available at that address.
You can do this by passing the wsdllocation option to the wsdl to java compiler.

Doing so will change your proxy code from

static {
    URL url = null;
    try {
        URL baseUrl;
        baseUrl = com.ibm.eci.soaservice.SOAService.class.getResource(".");
        url = new URL(baseUrl, "file:/C:/local/path/to/wsdl/SOAService.wsdl");
    } catch (MalformedURLException e) {
        logger.warning("Failed to create URL for the wsdl Location: 'file:/C:/local/path/to/wsdl/SOAService.wsdl', retrying as a local file");
        logger.warning(e.getMessage());
    }
    SOASERVICE_WSDL_LOCATION = url;
}

to

static {
    URL url = null;
    try {
        URL baseUrl;
        baseUrl = com.ibm.eci.soaservice.SOAService.class.getResource(".");
        url = new URL(baseUrl, "http://localhost/wsdl/SOAService.wsdl");
    } catch (MalformedURLException e) {
        logger.warning("Failed to create URL for the wsdl Location: 'http://localhost/wsdl/SOAService.wsdl', retrying as a local file");
        logger.warning(e.getMessage());
    }
    SOASERVICE_WSDL_LOCATION = url;
}

Notice file:// changed to http:// in the URL constructor.

Now comes in jax-ws-catalog.xml. Without jax-ws-catalog.xml jax-ws will indeed try to load the WSDL from the location

http://localhost/wsdl/SOAService.wsdl

But with jax-ws-catalog.xml you can redirect jax-ws to a locally packaged WSDL whenever it tries to access the WSDL @

http://localhost/wsdl/SOAService.wsdl

Here's jax-ws-catalog.xml

<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog" prefer="system">
        <system systemId="http://localhost/wsdl/SOAService.wsdl"
                uri="wsdl/SOAService.wsdl"/>
    </catalog>

What you are doing is telling jax-ws that when ever it needs to load WSDL from

http://localhost/wsdl/SOAService.wsdl

Now where should you put wsdl/SOAService.wsdl and jax-ws-catalog.xml ? That's the million dollar question isn't it ?
It should be in the META-INF directory of your application jar.

so something like this

ABCD.jar  
|__ META-INF    
    |__ jax-ws-catalog.xml  
    |__ wsdl  
        |__ SOAService.wsdl  

This way you don't even have to override the URL in your client that access the proxy. The WSDL is picked up from within your JAR, and you avoid having to have hard-coded filesystem paths in your code.

More info on jax-ws-catalog.xml http://jax-ws.java.net/nonav/2.1.2m1/docs/catalog-support.html

      <input type="button" onclick="retrieve_other()" value="Try Form" />
    </p>
  </form>

Output: Klaus or Andrew depending on what the selectedIndex is. If you are after the value just replace .text with value. However if it is just the value you are after (not the text in the option) then use document.getElementById('SMS_recipient').value

Not only white space, but my solution also solves the invisible characters as well.

str = "Hello I'm your String";
String[] splited = str.split("\p{Z}");

Following are few libraries to create PDF with Java:

1. iText
2. Apache PDFBox
3. BFO

I have used iText for genarating PDF's with a little bit of pain in the past.

Or you can try using FOP: FOP is an XSL formatter written in Java. It is used in conjunction with an XSLT transformation engine to format XML documents into PDF.

For an automatic letterbox/pillarbox in a fixed-size rectangle, use the object-fit CSS property. That is usually what I want, and it avoids using code to figure out which is the dominant dimension or — what I used to do — embedding an <SVG> element with an <image> child to wrap the content with its nice preserveAspectRatio options.

Use this html code it will surely help you

<input type="button" value="NEXT"  onclick="document.write('<?php //call a function here ex- 'fun();' ?>');" />

one limitation is that it is taking more time to run so wait for few seconds it will work

You can get MinGW (as others have suggested) but I would recommend getting a simple IDE (not VS Express). You can try Dev C++ http://www.bloodshed.net/devcpp.html Its a simple IDE for C/C++ and uses MinGW internally. In this you can write and compile single C files without creating a full-blown "project".

There are some already defined data types which allows us to iterate over them easily e.g Array, Map, String Objects

Normal for in iterates over the iterator and in response provides us with the keys that are in the order of insertion as shown in below example.

  const numbers = [1,2,3,4,5];
   for(let number in number) {
     console.log(number);
   }

   // result: 0, 1, 2, 3, 4

Now if we try same with for of, then in response it provides us with the values not the keys. e.g

  const numbers = [1,2,3,4,5];
   for(let numbers of numbers) {
    console.log(number);
  }

  // result: 1, 2, 3, 4, 5

So looking at both of the iterators we can easily differentiate the difference between both of them.

Note:- For of only works with the Symbol.iterator

So if we try to iterate over normal object, then it will give us an error e.g-

const Room = {
   area: 1000,
   height: 7,
   floor: 2
 }

for(let prop in Room) {
 console.log(prop);
 } 

// Result area, height, floor

for(let prop of Room) {
  console.log(prop);
 } 

Room is not iterable

Now for iterating over we need to define an ES6 Symbol.iterator e.g

  const Room= {
    area: 1000, height: 7, floor: 2,
   [Symbol.iterator]: function* (){
    yield this.area;
    yield this.height;
    yield this.floors;
  }
}


for(let prop of Room) {
  console.log(prop);
 } 

//Result 1000, 7, 2

This is the difference between For in and For of. Hope that it might clear the difference.

As mentioned in Alain Beauvois's answer, and now (Q4 2013) better explained in

• Eclipse for GitHub
• EGit 3.x manual (section "Starting from existing Git Repositories")
• Eclipse with GitHub
• EGit tutorial

Copy the URL from GitHub and select in Eclipse from the menu the

File ? Import ? Git ? Projects from Git

If the Git repo isn't cloned yet:

In> order to checkout a remote project, you will have to clone its repository first.
Open the Eclipse Import wizard (e.g. File => Import), select Git => Projects from Git and click Next.
Select “URI” and click Next.
Now you will have to enter the repository’s location and connection data. Entering the URI will automatically fill some fields. Complete any other required fields and hit Next. If you use GitHub, you can copy the URI from the web page.

Select all branches you wish to clone and hit Next again.

Hit the Clone… button to open another wizard for cloning Git repositories.

Original answer (July 2011)

First, if your "Working Directory" is C:\Users, that is odd, since it would mean you have cloned the GitHub repo directly within C:\Users (i.e. you have a .git directory in C:\Users)

Usually, you would clone a GitHub repo in "any directory of your choice\theGitHubRepoName".

As described in the EGit user Manual page:

In any case (unless you create a "bare" Repository, but that's not discussed here), the new Repository is essentially a folder on the local hard disk which contains the "working directory" and the metadata folder.
The metadata folder is a dedicated child folder named ".git" and often referred to as ".git-folder". It contains the actual repository (i.e. the Commits, the References, the logs and such).

The metadata folder is totally transparent to the Git client, while the working directory is used to expose the currently checked out Repository content as files for tools and editors.

Typically, if these files are to be used in Eclipse, they must be imported into the Eclipse workspace in one way or another. In order to do so, the easiest way would be to check in .project files from which the "Import Existing Projects" wizard can create the projects easily. Thus in most cases, the structure of a Repository containing Eclipse projects would look similar to something like this:

See also the Using EGit with Github section.

My working directory is now c:\users\projectname\.git

You should have the content of that repo checked out in c:\users\projectname (in other words, you should have more than just the .git).

So then I try to import the project using the eclipse "import" option.
When I try to import selecting the option "Use the new projects wizard", the source code is not imported.

That is normal.

If I import selecting the option "Import as general project" the source code is imported but the created project created by Eclipse is not a java project.

Again normal.

When selecting the option "Use the new projects wizard" and creating a new java project using the wizard should'nt the code be automatically imported ?

No, that would only create an empty project.
If that project is created in c:\users\projectname, you can then declare the eisting source directory in that project.
Since it is defined in the same working directory than the Git repo, that project should then appear as "versioned".

You could also use the "Import existing project" option, if your GitHub repo had versioned the .project and .classpath file, but that may not be the case here.

Update:

These articles in my blog describe the differences between the methods in more detail:

• NOT IN vs. NOT EXISTS vs. LEFT JOIN / IS NULL: SQL Server
• NOT IN vs. NOT EXISTS vs. LEFT JOIN / IS NULL: PostgreSQL
• NOT IN vs. NOT EXISTS vs. LEFT JOIN / IS NULL: Oracle
• NOT IN vs. NOT EXISTS vs. LEFT JOIN / IS NULL: MySQL

There are three ways to do such a query:

• LEFT JOIN / IS NULL:

  SELECT  *
  FROM    common
  LEFT JOIN
          table1 t1
  ON      t1.common_id = common.common_id
  WHERE   t1.common_id IS NULL
  

• NOT EXISTS:

  SELECT  *
  FROM    common
  WHERE   NOT EXISTS
          (
          SELECT  NULL
          FROM    table1 t1
          WHERE   t1.common_id = common.common_id
          )
  

• NOT IN:

  SELECT  *
  FROM    common
  WHERE   common_id NOT IN
          (
          SELECT  common_id
          FROM    table1 t1
          )
  

When table1.common_id is not nullable, all these queries are semantically the same.

When it is nullable, NOT IN is different, since IN (and, therefore, NOT IN) return NULL when a value does not match anything in a list containing a NULL.

This may be confusing but may become more obvious if we recall the alternate syntax for this:

common_id = ANY
(
SELECT  common_id
FROM    table1 t1
)

The result of this condition is a boolean product of all comparisons within the list. Of course, a single NULL value yields the NULL result which renders the whole result NULL too.

We never cannot say definitely that common_id is not equal to anything from this list, since at least one of the values is NULL.

Suppose we have these data:

common

--
1
3

table1

--
NULL
1
2

LEFT JOIN / IS NULL and NOT EXISTS will return 3, NOT IN will return nothing (since it will always evaluate to either FALSE or NULL).

In MySQL, in case on non-nullable column, LEFT JOIN / IS NULL and NOT IN are a little bit (several percent) more efficient than NOT EXISTS. If the column is nullable, NOT EXISTS is the most efficient (again, not much).

In Oracle, all three queries yield same plans (an ANTI JOIN).

In SQL Server, NOT IN / NOT EXISTS are more efficient, since LEFT JOIN / IS NULL cannot be optimized to an ANTI JOIN by its optimizer.

In PostgreSQL, LEFT JOIN / IS NULL and NOT EXISTS are more efficient than NOT IN, sine they are optimized to an Anti Join, while NOT IN uses hashed subplan (or even a plain subplan if the subquery is too large to hash)

If you'd like to use Code Behind, may I suggest the following solution for an asp:button -

ASPX Page

<asp:Button ID="btnRecover" runat="server" Text="Recover" OnClick="btnRecover_Click" />

Code Behind

    protected void btnRecover_Click(object sender, EventArgs e)
    {
        var recoveryId = Guid.Parse(lbRecovery.SelectedValue);
        var url = string.Format("{0}?RecoveryId={1}", @"../Recovery.aspx", vehicleId);

        // Response.Redirect(url); // Old way

        Response.Write("<script> window.open( '" + url + "','_blank' ); </script>");
        Response.End();
    }

More generic way - use file structure to determine bitness and image type:

public static CompilationMode GetCompilationMode(this FileInfo info)
{
    if (!info.Exists) throw new ArgumentException($"{info.FullName} does not exist");

    var intPtr = IntPtr.Zero;
    try
    {
        uint unmanagedBufferSize = 4096;
        intPtr = Marshal.AllocHGlobal((int)unmanagedBufferSize);

        using (var stream = File.Open(info.FullName, FileMode.Open, FileAccess.Read))
        {
            var bytes = new byte[unmanagedBufferSize];
            stream.Read(bytes, 0, bytes.Length);
            Marshal.Copy(bytes, 0, intPtr, bytes.Length);
        }

        //Check DOS header magic number
        if (Marshal.ReadInt16(intPtr) != 0x5a4d) return CompilationMode.Invalid;

        // This will get the address for the WinNT header  
        var ntHeaderAddressOffset = Marshal.ReadInt32(intPtr + 60);

        // Check WinNT header signature
        var signature = Marshal.ReadInt32(intPtr + ntHeaderAddressOffset);
        if (signature != 0x4550) return CompilationMode.Invalid;

        //Determine file bitness by reading magic from IMAGE_OPTIONAL_HEADER
        var magic = Marshal.ReadInt16(intPtr + ntHeaderAddressOffset + 24);

        var result = CompilationMode.Invalid;
        uint clrHeaderSize;
        if (magic == 0x10b)
        {
            clrHeaderSize = (uint)Marshal.ReadInt32(intPtr + ntHeaderAddressOffset + 24 + 208 + 4);
            result |= CompilationMode.Bit32;
        }
        else if (magic == 0x20b)
        {
            clrHeaderSize = (uint)Marshal.ReadInt32(intPtr + ntHeaderAddressOffset + 24 + 224 + 4);
            result |= CompilationMode.Bit64;
        }
        else return CompilationMode.Invalid;

        result |= clrHeaderSize != 0
            ? CompilationMode.CLR
            : CompilationMode.Native;

        return result;
    }
    finally
    {
        if (intPtr != IntPtr.Zero) Marshal.FreeHGlobal(intPtr);
    }
}

Compilation mode enumeration

[Flags]
public enum CompilationMode
{
    Invalid = 0,
    Native = 0x1,
    CLR = Native << 1,
    Bit32 = CLR << 1,
    Bit64 = Bit32 << 1
}

If anyone looking for Intialization error

Can't connect to database "/var/run/mysql/mysql.sock"

When running civicrm & drupal just make below changes in

settings.php and civicrm.settings.php

only in places where you try to establish db connection

localhost to 127.0.0.1 #local installation

You have set the upstream of that branch

(see:

• "How do you make an existing git branch track a remote branch?" and
• "Git: Why do I need to do --set-upstream-to all the time?"
  )

git branch -f --track my_local_branch origin/my_remote_branch
# OR (if my_local_branch is currently checked out):
$ git branch --set-upstream-to my_local_branch origin/my_remote_branch

(git branch -f --track won't work if the branch is checked out: use the second command git branch --set-upstream-to instead, or you would get "fatal: Cannot force update the current branch.")

That means your branch is already configured with:

branch.my_local_branch.remote origin
branch.my_local_branch.merge my_remote_branch

Git already has all the necessary information.
In that case:

# if you weren't already on my_local_branch branch:
git checkout my_local_branch 
# then:
git pull

is enough.

If you hadn't establish that upstream branch relationship when it came to push your 'my_local_branch', then a simple git push -u origin my_local_branch:my_remote_branch would have been enough to push and set the upstream branch.
After that, for the subsequent pulls/pushes, git pull or git push would, again, have been enough.

Simplified example (with counter):

With Me.lstbox
    .ColumnCount = 2
    .ColumnWidths = "60;60"
    .AddItem
    .List(i, 0) = Company_ID
    .List(i, 1) = Company_name 
    i = i + 1

end with

Make sure to start the counter with 0, not 1 to fill up a listbox.

var word = document.getElementById("word").value;//by id
or
var word = document.forms[0].elements[0].value;//by index
//word = a word from form input
var kodlandi = escape(word);//apply url encoding

alert(escape(word));
or
alert(kodlandi);

the problem you are not using encoding for input values from form so not browser adds ones to ...

ontop has some problems as unicode encoding/decoding operations so use this function encoding strings/arrays

function urlencode( str ) 
{
// http://kevin.vanzonneveld.net3.    
// +   original by: Philip Peterson4.    
// +   improved by: Kevin van Zonneveld (http://kevin.vanzonneveld.net)5.    
// *     example 1: urlencode('Kevin van Zonneveld!');
// *     returns 1: 'Kevin+van+Zonneveld%21'7. 
   var ret = str; 
   ret = ret.toString();
   ret = encodeURIComponent(ret);
   ret = ret.replace(/%20/g, '+');
   return ret;
}


ex.
var word = "some word";
word = urlencode(word);

Inspired from it, an approach can be made by creating a temporary table and inserting the constraints in that table, and then dropping the constraints and then reapplying them from that temporary table. Enough said here is what i am talking about

 SET NOCOUNT ON

    DECLARE @temptable TABLE(
       Id INT PRIMARY KEY IDENTITY(1, 1),
       FKConstraintName VARCHAR(255),

       FKConstraintColumnName VARCHAR(255),
       PKConstraintName VARCHAR(255),
       PKConstraintTableSchema VARCHAR(255),
       PKConstraintTableName VARCHAR(255),
       PKConstraintColumnName VARCHAR(255)    
    )

    INSERT INTO @temptable(FKConstraintName, FKConstraintTableSchema, FKConstraintTableName, FKConstraintColumnName)
    SELECT 
       KeyColumnUsage.CONSTRAINT_NAME, 
       KeyColumnUsage.TABLE_SCHEMA,

It's not working because console.log() it's not in a "executable area" of the class "App".

A class is a structure composed by attributes and methods.

The only way to have your code executed is to place it inside a method that is going to be executed. For instance: constructor()

console.log('It works here')_x000D_
_x000D_
@Component({..)_x000D_
export class App {_x000D_
 s: string = "Hello2";_x000D_
            _x000D_
  constructor() {_x000D_
    console.log(this.s)            _x000D_
  }            _x000D_
}

Think of class like a plain javascript object.

Would it make sense to expect this to work?

class:  {_x000D_
  s: string,_x000D_
  console.log(s)_x000D_
 }

If you still unsure, try the typescript playground where you can see your typescript code generated into plain javascript.

Well, of course, this doesn't apply to all projects. Still, QCoreApplication::applicationFilePath() never failed me in 6 years of C++/Qt development.

Of course, one should read documentation thoroughly before attempting to use it:

Warning: On Linux, this function will try to get the path from the /proc file system. If that fails, it assumes that argv[0] contains the absolute file name of the executable. The function also assumes that the current directory has not been changed by the application.

To be honest, I think that #ifdef and other solutions like that shouldn't be used in modern code at all.

I'm sure that smaller cross-platform libraries also exist. Let them encapsulate all that platform-specific stuff inside.

If you move from iframes, you may get lost in your page, best way to execute some jquery without issue (with selenimum/python/gecko):

# 1) Get back to the main body page
driver.switch_to.default_content()

# 2) Download jquery lib file to your current folder manually & set path here
with open('./_lib/jquery-3.3.1.min.js', 'r') as jquery_js: 
    # 3) Read the jquery from a file
    jquery = jquery_js.read() 
    # 4) Load jquery lib
    driver.execute_script(jquery)
    # 5) Execute your command 
    driver.execute_script('$("#myId").click()')

Simple Solution from ascending to descending and vice versa is:

STRINGS

str = ['ravi', 'aravind', 'joker', 'poker']
asc_string = str.sort # => ["aravind", "joker", "poker", "ravi"]
asc_string.reverse # => ["ravi", "poker", "joker", "aravind"]

DIGITS

digit = [234,45,1,5,78,45,34,9]
asc_digit = digit.sort # => [1, 5, 9, 34, 45, 45, 78, 234]
asc_digit.reverse # => [234, 78, 45, 45, 34, 9, 5, 1]

This feature is available in the standard build now. To make the collapse/expand controls appears, you need to mouse over the area just to the right of the line numbers as shown in this screenshot:

With the new and popular f-strings in Python 3.6, here is how we left-align say a string with 16 padding length:

string = "Stack Overflow"
print(f"{string:<16}..")
Stack Overflow  ..

If you have variable padding length:

k = 20
print(f"{string:<{k}}..")
Stack Overflow      .. 

f-strings are more compact.

Change it to:

  std::string s;
  std::string* pS = &s;
  myfunc(pS);

EDIT:

This is called ref-to-pointer and you cannot pass temporary address as a reference to function. ( unless it is const reference).

Though, I have shown std::string* pS = &s; (pointer to a local variable), its typical usage would be : when you want the callee to change the pointer itself, not the object to which it points. For example, a function that allocates memory and assigns the address of the memory block it allocated to its argument must take a reference to a pointer, or a pointer to pointer:

void myfunc(string*& val)
{
//val is valid even after function call
   val = new std::string("Test");

}

I was facing the same problem. I used e.getCause().getCause() then I found that it was because of wrong parameters I was passing. There was nullPointerException in fetching the value of one of the parameters. Hope this will help you.

You can try this:

sales['time_hour'] = pd.to_datetime(sales['timestamp']).dt.hour

In my case, the svn relocate command (as well as svn switch --relocate) failed for some reason (maybe the repo was not moved correctly, or something else). I faced this error:

$ svn relocate NEW_SERVER
svn: E195009: The repository at 'NEW_SERVER' has uuid 'e7500204-160a-403c-b4b6-6bc4f25883ea', but the WC has '3a8c444c-5998-40fb-8cb3-409b74712e46'

I did not want to redownload the whole repository, so I found a workaround. It worked in my case, but generally I can imagine a lot of things can get broken (so either backup your working copy, or be ready to re-checkout the whole repo if something goes wrong).

The repo address and its UUID are saved in the .svn/wc.db SQLite database file in your working copy. Just open the database (e.g. in SQLite Browser), browse table REPOSITORY, and change the root and uuid column values to the new ones. You can find the UUID of the new repo by issuing svn info NEW_SERVER.

Again, treat this as a last resort method.

Right click on your project -> Android Tool -> Add support library

This is here:

 <button onClick="window.location='page_name.php';" value="click here" />

In order to avoid having to fully specify the git push command you could alternatively modify your git config file:

[remote "gerrit"]
    url = https://your.gerrit.repo:44444/repo
    fetch = +refs/heads/master:refs/remotes/origin/master
    push = refs/heads/master:refs/for/master

Now you can simply:

git fetch gerrit
git push gerrit

This is according to Gerrit

Postgresql historically doesn't support procedural code at the command level - only within functions. However, in Postgresql 9, support has been added to execute an inline code block that effectively supports something like this, although the syntax is perhaps a bit odd, and there are many restrictions compared to what you can do with SQL Server. Notably, the inline code block can't return a result set, so can't be used for what you outline above.

In general, if you want to write some procedural code and have it return a result, you need to put it inside a function. For example:

CREATE OR REPLACE FUNCTION somefuncname() RETURNS int LANGUAGE plpgsql AS $$
DECLARE
  one int;
  two int;
BEGIN
  one := 1;
  two := 2;
  RETURN one + two;
END
$$;
SELECT somefuncname();

The PostgreSQL wire protocol doesn't, as far as I know, allow for things like a command returning multiple result sets. So you can't simply map T-SQL batches or stored procedures to PostgreSQL functions.

even shorter if you can lose the yearStart value:

var yearStart = 2000;
var yearEnd = 2040;

var arr = [];

while(yearStart < yearEnd+1){
  arr.push(yearStart++);
}

UPDATE: If you can use the ES6 syntax you can do it the way proposed here:

let yearStart = 2000;
let yearEnd = 2040;
let years = Array(yearEnd-yearStart+1)
    .fill()
    .map(() => yearStart++);

The ALL_DIRECTORIES data dictionary view will have information about all the directories that you have access to. That includes the operating system path

SELECT owner, directory_name, directory_path
  FROM all_directories

Use it like this to allow for single space.

$newtag = preg_replace("/[^a-zA-Z0-9\s]/", "", $tag)

Place the link location in the action="" of a wrapping form tag.

Your first link would be:

<form action="1.html">
    <input type="submit" class="button_active" value="1">
</form>

For ones who got permission denied for saving operation, here is the command that worked for me:

$ curl https://www.python.org/static/apple-touch-icon-144x144-precomposed.png --output py.png

You can just replace like this,

 var someString = "23/03/2012";
 someString.replace(/\//g, "-");

It works for me..

 public static string RandomString(int length)
    {
        const string chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
        var random = new Random();
        return new string(Enumerable.Repeat(chars, length).Select(s => s[random.Next(s.Length)]).ToArray());
    }

Is this what you are looking for?

converting from String to byte

byte b = (byte)(int)Integer.valueOf("10000010", 2);
System.out.println(b);// output -> -126

converting from byte to String

System.out.println(Integer.toBinaryString((b+256)%256));// output -> "10000010"

Or as João Silva said in his comment to add leading 0 we can format string to length 8 and replace resulting leading spaces with zero, so in case of string like " 1010" we will get "00001010"

System.out.println(String.format("%8s", Integer.toBinaryString((b + 256) % 256))
                         .replace(' ', '0'));

The number of itemIds in your list will be the same as the number of elements in your list:

int itemCount = list.size();

However, if you're looking to count the number of unique itemIds (per @pst) then you should use a set to keep track of them.

Set<String> itemIds = new HashSet<String>();

//...
itemId = p.getItemId();
itemIds.add(itemId);

//... later ...
int uniqueItemIdCount = itemIds.size();

I think you can use REGEXP instead of LIKE

SELECT trecord FROM `tbl` WHERE (trecord REGEXP '^ALA[0-9]')

No need for regex. This will also remove tabs, newlines etc

var newstr = String.Join("",str.Where(c=>!char.IsWhiteSpace(c)));

WhiteSpace chars : 0009 , 000a , 000b , 000c , 000d , 0020 , 0085 , 00a0 , 1680 , 180e , 2000 , 2001 , 2002 , 2003 , 2004 , 2005 , 2006 , 2007 , 2008 , 2009 , 200a , 2028 , 2029 , 202f , 205f , 3000.

When you click on the image you'll get the alert:

<img src="logo1.jpg" onClick='alert("Hello World!")'/>

if this is what you want.

It's very simple. You need just two lines of code with just using the built-in function and also it takes the input and runs forever until you stop it. Also that 'cmd' in quotes, leave it and don't change it. Here is the code:

import os
os.system('cmd')

Now just run this code and see the whole windows command prompt in your python project!

Take a look at this answer: ImportError: no module named win32api

You can use

pip install pypiwin32

-l (that's a lower-case L).

According to MSDN, e.AddedItems:

Gets a list that contains the items that were selected.

So you could use:

private void OnMyComboBoxChanged(object sender, SelectionChangedEventArgs e)
{
    string text = (e.AddedItems[0] as ComboBoxItem).Content as string;
}

You could also use SelectedItem if you use string values for the Items from the sender:

private void OnMyComboBoxChanged(object sender, SelectionChangedEventArgs e)
{
    string text = (sender as ComboBox).SelectedItem as string;
}

or

private void OnMyComboBoxChanged(object sender, SelectionChangedEventArgs e)
{
    string text = ((sender as ComboBox).SelectedItem as ComboBoxItem).Content as string;
}

Since both Content and SelectedItem are objects, a safer approach would be to use .ToString() instead of as string

To understand it you have to declare the method in the simplest way possible and martynas nailed it on May 6th post:

int fact(int n) {
    if(n==0) return 1;
    else return n * fact(n-1);
}

read the above implementation and you will understand.

What you are trying to do is not possible. The reason for this is that in a POSIX system (Linux, OSX, etc), a child process cannot modify the environment of a parent process. This includes modifying the parent process's working directory and environment variables.

When you are on the commandline and you go to execute your Node script, your current process (bash, zsh, whatever) spawns a new process which has it's own environment, typically a copy of your current environment (it is possible to change this via system calls; but that's beyond the scope of this reply), allowing that process to do whatever it needs to do in complete isolation. When the subprocess exits, control is handed back to your shell's process, where the environment hasn't been affected.

There are a lot of reasons for this, but for one, imagine that you executed a script in the background (via ./foo.js &) and as it ran, it started changing your working directory or overriding your PATH. That would be a nightmare.

If you need to perform some actions that require changing your working directory of your shell, you'll need to write a function in your shell. For example, if you're running Bash, you could put this in your ~/.bash_profile:

do_cool_thing() {
  cd "/Users"
  echo "Hey, I'm in $PWD"
}

and then this cool thing is doable:

$ pwd
/Users/spike
$ do_cool_thing
Hey, I'm in /Users
$ pwd
/Users

If you need to do more complex things in addition, you could always call out to your nodejs script from that function.

This is the only way you can accomplish what you're trying to do.

In the .gitconfig file you can add the below given value to make the self signed cert acceptable

sslCAInfo = /home/XXXX/abc.crt

A very portable version (even to legacy bourne shell):

if [ "$varA" = 1 -a \( "$varB" = "t1" -o "$varB" = "t2" \) ]
then    do-something
fi

This has the additional quality of running only one subprocess at most (which is the process [), whatever the shell flavor.

Replace = with -eq if variables contain numeric values, e.g.

• 3 -eq 03 is true, but
• 3 = 03 is false. (string comparison)

The suggestion from @Dawood is good if that works for you.

If you need more fine-tuning than that, one option is to use padding on the text elements, here's an example: http://jsfiddle.net/panchroma/FtBwe/

CSS

p, h2 {
    padding-left:10px;
}

With CSS Shapes you can go one step further than just float text around a rectangular image.

You can actually wrap text such that it takes the shape of the edge of the image or polygon that you are wrapping it around.

try this way:

var difList = list1.Where(a => !list2.Any(a1 => a1.id == a.id))
            .Union(list2.Where(a => !list1.Any(a1 => a1.id == a.id)));

unset is the command you're looking for.

In JavaScript, null is an object. There's another value for things that don't exist, undefined. The DOM returns null for almost all cases where it fails to find some structure in the document, but in JavaScript itself undefined is the value used.

Second, no, there is not a direct equivalent. If you really want to check for specifically for null, do:

if (yourvar === null) // Does not execute if yourvar is `undefined`

If you want to check if a variable exists, that can only be done with try/catch, since typeof will treat an undeclared variable and a variable declared with the value of undefined as equivalent.

But, to check if a variable is declared and is not undefined:

if (yourvar !== undefined) // Any scope

Previously, it was necessary to use the typeof operator to check for undefined safely, because it was possible to reassign undefined just like a variable. The old way looked like this:

if (typeof yourvar !== 'undefined') // Any scope

The issue of undefined being re-assignable was fixed in ECMAScript 5, which was released in 2009. You can now safely use === and !== to test for undefined without using typeof as undefined has been read-only for some time.

If you want to know if a member exists independent but don't care what its value is:

if ('membername' in object) // With inheritance
if (object.hasOwnProperty('membername')) // Without inheritance

If you want to to know whether a variable is truthy:

if (yourvar)

A good way to force your CSS to reload is to:

<link href='styles.css?version=1' rel='stylesheet'></link>

And then just increment the version number as you change your CSS. The browser will then obey. I believe StackOverflow uses this technique.

$("#expires1").click(function(){
     if (this.checked)
        alert("testing....");
});

To just find the number of days: timedelta has a 'days' attribute. You can simply query that.

>>>from datetime import datetime, timedelta
>>>d1 = datetime(2015, 9, 12, 13, 9, 45)
>>>d2 = datetime(2015, 8, 29, 21, 10, 12)
>>>d3 = d1- d2
>>>print d3
13 days, 15:59:33
>>>print d3.days
13

I'm not sure what you're doing, but this will go from JSON to CSV using JavaScript. This is using the open source JSON library, so just download JSON.js into the same folder you saved the code below into, and it will parse the static JSON value in json3 into CSV and prompt you to download/open in Excel.

    function DownloadJSON2CSV(objArray)

        var array = typeof objArray != 'object' ? JSON.parse(objArray) : objArray;

        var str = '';

        for (var i = 0; i < array.length; i++) {
            var line = '';

            for (var index in array[i]) {
                line += array[i][index] + ',';

Most Easy way typecast string number to integer

You can use CSS3 transitions or maybe CSS3 animations to slide in an element.

For browser support: http://caniuse.com/

I made two quick examples just to show you how I mean.

CSS transition (on hover)

Demo One

Relevant Code

.wrapper:hover #slide {
    transition: 1s;
    left: 0;
}

In this case, Im just transitioning the position from left: -100px; to 0; with a 1s. duration. It's also possible to move the element using transform: translate();

CSS animation

Demo Two

#slide {
    position: absolute;
    left: -100px;
    width: 100px;
    height: 100px;
    background: blue;
    -webkit-animation: slide 0.5s forwards;
    -webkit-animation-delay: 2s;
    animation: slide 0.5s forwards;
    animation-delay: 2s;
}

@-webkit-keyframes slide {
    100% { left: 0; }
}

@keyframes slide {
    100% { left: 0; }
}

Same principle as above (Demo One), but the animation starts automatically after 2s, and in this case I've set animation-fill-mode to forwards, which will persist the end state, keeping the div visible when the animation ends.

Like I said, two quick example to show you how it could be done.

EDIT: For details regarding CSS Animations and Transitions see:

Transitions

Hope this helped.

In my case, to use Pageable and Sorting at the same time I used like below. In this case I took all elements using pagination and sorting by id by descending order:

modelRepository.findAll(PageRequest.of(page, 10, Sort.by("id").descending()))

Like above based on your requirements you can sort data with 2 columns as well.

If you want exactly 40 spaces before the string then you should just do:

printf("                                        %s\n", myStr );

If that is too dirty, you can do (but it will be slower than manually typing the 40 spaces): printf("%40s%s", "", myStr );

If you want the string to be lined up at column 40 (that is, have up to 39 spaces proceeding it such that the right most character is in column 40) then do this: printf("%40s", myStr);

You can also put "up to" 40 spaces AfTER the string by doing: printf("%-40s", myStr);

I had the same requirement for a project I am doing. But none of the answers came elegant to my requirement. Here is something which finally helped me, and might be useful for this case:

from bokeh.io import export_png, export_svgs
from bokeh.models import ColumnDataSource, DataTable, TableColumn

def save_df_as_image(df, path):
    source = ColumnDataSource(df)
    df_columns = [df.index.name]
    df_columns.extend(df.columns.values)
    columns_for_table=[]
    for column in df_columns:
        columns_for_table.append(TableColumn(field=column, title=column))

    data_table = DataTable(source=source, columns=columns_for_table,height_policy="auto",width_policy="auto",index_position=None)
    export_png(data_table, filename = path)

I had the same problem. I wrote my own function using replace on innerHTML, but it would screw up anchor links and such.

To make it work correctly I used a library to get this done.

The library has an awesome API. After including the script I called it like this:

findAndReplaceDOMText(document.body, {
  find: 'texttofind',
  replace: 'texttoreplace'
  }
);

check this Twig Reference.

You can do it that simple:

{% if (a or b) %}
    ...
{% endif %}

You can download the required files from the Microsoft website or online or reinstall the Visual studio 2012 to fix this.

Theory

Why it is hard

Popular font formats like TrueType and OpenType are vector outline formats: they use Bezier curves to define the boundary of the letter.

Image source.

Transforming those formats into arrays of pixels (rasterization) is too specific and out of OpenGL's scope, specially because OpenGl does not have non-straight primitives (e.g. see Why is there no circle or ellipse primitive in OpenGL?)

The easiest approach is to first raster fonts ourselves on the CPU, and then give the array of pixels to OpenGL as a texture.

OpenGL then knows how to deal with arrays of pixels through textures very well.

Texture atlas

We could raster characters for every frame and re-create the textures, but that is not very efficient, specially if characters have a fixed size.

The more efficient approach is to raster all characters you plan on using and cram them on a single texture.

And then transfer that to the GPU once, and use it texture with custom uv coordinates to choose the right character.

This approach is called a texture atlas and it can be used not only for textures but also other repeatedly used textures, like tiles in a 2D game or web UI icons.

The Wikipedia picture of the full texture, which is itself taken from freetype-gl, illustrates this well:

I suspect that optimizing character placement to the smallest texture problem is an NP-hard problem, see: What algorithm can be used for packing rectangles of different sizes into the smallest rectangle possible in a fairly optimal way?

The same technique is used in web development to transmit several small images (like icons) at once, but there it is called "CSS Sprites": https://css-tricks.com/css-sprites/ and are used to hide the latency of the network instead of that of the CPU / GPU communication.

Non-CPU raster methods

There also exist methods which don't use the CPU raster to textures.

CPU rastering is simple because it uses the GPU as little as possible, but we also start thinking if it would be possible to use the GPU efficiency further.

This FOSDEM 2014 video explains other existing techniques:

• tesselation: convert the font to tiny triangles. The GPU is then really good at drawing triangles. Downsides:
  • generates a bunch of triangles
  • O(n log n) CPU calculation of the triangles
• calculate curves on shaders. A 2005 paper by Blinn-Loop put this method on the map. Downside: complex. See: Resolution independent cubic bezier drawing on GPU (Blinn/Loop)
• direct hardware implementations like OpenVG. Downside: not very widely implemented for some reason. See:
  • OpenGL, OpenVG. Draw text?
  • OpenVG implementation?

Fonts inside of the 3D geometry with perspective

Rendering fonts inside of the 3D geometry with perspective (compared to an orthogonal HUD) is much more complicated, because perspective could make one part of the character much closer to the screen and larger than the other, making an uniform CPU discretization (e.g. raster, tesselation) look bad on the close part. This is actually an active research topic:

• What is state-of-the-art for text rendering in OpenGL as of version 4.1?
• http://www.valvesoftware.com/publications/2007/SIGGRAPH2007_AlphaTestedMagnification.pdf

Distance fields are one of the popular techniques now.

Implementations

The examples that follow were all tested on Ubuntu 15.10.

Because this is a complex problem as discussed previously, most examples are large, and would blow up the 30k char limit of this answer, so just clone the respective Git repositories to compile.

They are all fully open source however, so you can just RTFS.

FreeType solutions

FreeType looks like the dominant open source font rasterization library, so it would allow us to use TrueType and OpenType fonts, making it the most elegant solution.

• https://github.com/rougier/freetype-gl

  Was a set of examples OpenGL and freetype, but is more or less evolving into a library that does it and exposes a decent API.

  In any case, it should already be possible to integrate it on your project by copy pasting some source code.

  It provides both texture atlas and distance field techniques out of the box.

  Demos under: https://github.com/rougier/freetype-gl/tree/master/demos

  Does not have a Debian package, and it a pain to compile on Ubuntu 15.10: https://github.com/rougier/freetype-gl/issues/82#issuecomment-216025527 (packaging issues, some upstream), but it got better as of 16.10.

  Does not have a nice installation method: https://github.com/rougier/freetype-gl/issues/115

  Generates beautiful outputs like this demo:

  

• libdgx https://github.com/libgdx/libgdx/tree/1.9.2/extensions/gdx-freetype

Examples / tutorials:

• a NEHE tutorial: http://nehe.gamedev.net/tutorial/freetype_fonts_in_opengl/24001/
• http://learnopengl.com/#!In-Practice/Text-Rendering mentions it, but I could not find runnable source code
• SO questions:
  • OpenGL font rendering using Freetype2
  • Text not rendering correctly - OpenGL using FreeType2

Other font rasterizers

Those seem less good than FreeType, but may be more lightweight:

Lives in a separate tree to SDL, and integrates easily.

Does not provide a texture atlas implementation however, so performance will be limited: How to render fonts and text with SDL2 efficiently?

I'm not sure it's a standard construct, but I think you should have a look on "negative lookahead" (which writes : "?!", without the quotes). It's far easier than all answers in this thread, including the accepted one.

Example : Regex : "^(?!123)[0-9]*\w" Captures any string beginning by digits followed by letters, UNLESS if "these digits" are 123.

http://msdn.microsoft.com/en-us/library/az24scfc%28v=vs.110%29.aspx#grouping_constructs (microsoft page, but quite comprehensive) for lookahead / lookbehind

PS : it works well for me (.Net). But if I'm wrong on something, please let us know. I find this construct very simple and effective, so I'm surprised of the accepted answer.

There is a boolean contains(Object obj) method within the List interface.

You should be able to say:

if (list.contains("a")) {
    System.out.println("It's there");
}

According to the javadoc:

boolean contains(Object o)

Returns true if this list contains the specified element.
More formally, returns true if and only if this list contains at
least one element e such that (o==null ? e==null : o.equals(e)).

OK. We have official document now. It talked all I have mentioned, in a better way.

Read more detailed here.

Yes, the main difference is surfaceView can be updated on the background thread. However, there are more you might care.

• surfaceView has dedicate surface buffer while all the view shares one surface buffer that is allocated by ViewRoot. In another word, surfaceView cost more resources.

• surfaceView cannot be hardware accelerated (as of JB4.2) while 95% operations on normal View are HW accelerated using openGL ES.

• More work should be done to create your customized surfaceView. You need to listener to the surfaceCreated/Destroy Event, create an render thread, more importantly, synchronized the render thread and main thread. However, to customize the View, all you need to do is override onDraw method.

• The timing to update is different. Normal view update mechanism is constraint or controlled by the framework:You call view.invalidate in the UI thread or view.postInvalid in other thread to indicate to the framework that the view should be updated. However, the view won't be updated immediately but wait until next VSYNC event arrived. The easy approach to understand VSYNC is to consider it is as a timer that fire up every 16ms for a 60fps screen. In Android, all the normal view update (and display actually but I won't talk it today), is synchronized with VSYNC to achieve better smoothness. Now,back to the surfaceView, you can render it anytime as you wish. However, I can hardly tell if it is an advantage, since the display is also synchronized with VSYNC, as stated previously.

Give the below

@ContextConfiguration(locations =  {"classpath*:/spring/test-context.xml"})

And in pom.xml give the following plugin:

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-surefire-plugin</artifactId>
   <version>2.20.1</version>
<configuration>
    <additionalClasspathElements>
       <additionalClasspathElement>${basedir}/src/test/resources</additionalClasspathElement>
    </additionalClasspathElements>

We have used SharpZipLib successfully on many projects. I know it's a third party tool, but source code is included and could provide some insight if you chose to reinvent the wheel here.

I came across this error while making a segue from a table view controller to a view controller because I had forgotten to specify the custom class name for the view controller in the main storyboard.

Something simple that is worth checking if all else looks ok

Use the return keyword.

return; //exit this event

Your PFX file should contain the private key within it. Export the private key and certificate directly from your PFX file (e.g. using OpenSSL) and import them into your Java keystore.

Edit

Further information:

• Download OpenSSL for Windows here.
• Export private key: openssl pkcs12 -in filename.pfx -nocerts -out key.pem
• Export certificate: openssl pkcs12 -in filename.pfx -clcerts -nokeys -out cert.pem
• Import private key and certificate into Java keystore using keytool.

Yes, you could also use COALESCE(@value,'')='' which is based on the ANSI SQL standard:

SELECT CASE WHEN COALESCE(@value,'')='' 
    THEN 'Yes, it is null or empty' ELSE 'No, not null or empty' 
    END AS IsNullOrEmpty

NOTE: You should use an HTML Parser like DOMDocument and NOT a regex.

You would need to create a generic class named MyProp. Then, you will need to add implicit or explicit cast operators so you can get and set the value as if it were the type specified in the generic type parameter. These cast operators can do the extra work that you need.

Yes, div can take as many classes as you need. Use space to separate one from another.

 <div class="active dropdown-toggle custom-class">Example of multiple classses</div>

I had the same problem, reason was I defined schema an model in a JS function, they should be defined globally in a node module, not in a function.

i think sometimes stop the redis-server and delete rdb,aof files? make sure there’s no data can be reloading. then start the redis-server,now it's new and empty.

Or try this ;)

try {
  this.setContentPane(
    new JLabel(new ImageIcon(ImageIO.read(new File("your_file.jpeg")))));
} catch (IOException e) {};

I created three dropdowns for Date of Birth selection and number of days changes dynamically based on the year and month selection. http://jsfiddle.net/ravitejagunda/FH4VB/10/

I used the following solution:

1. Convert .svg image to JSX with https://svg2jsx.herokuapp.com/
2. Convert the JSX to react-native-svg component with https://svgr.now.sh/ (check the "React Native checkbox)

Use strlen() instead. I ran onto the same issue using 1/0 as possible values for some variables. I am using if (strlen($_POST['myValue']) == 0) to test if there is a character or not in my variable.

Here's a nice hack for windows

process.on('exit', async () => {
    require('fs').writeFileSync('./tmp.js', 'crash', 'utf-8')
});

On my PC, xcopy and robocopy need also the path to them, i.e. C:\Windows\System32\xcopy.exe

That's why I use simply "copy": copy /y ....\Folder1\File.txt ....\Folder2\

The others did not work in my case (Bootstrap 4). Here is the solution I used.

html .form-control::-webkit-input-placeholder { color:white; }
html .form-control:-moz-placeholder { color:white; }
html .form-control::-moz-placeholder { color:white; }
html .form-control:-ms-input-placeholder { color:white; }

If we use a stronger selector (html first), we don't need to use the hacky value !important.

This overrides bootstraps CSS as we use a higher level of specificity to target .form-control elements (html first instead of .form-control first).

A regular for loop is pretty concise:

var total = 0;

for (var property in object) {
    total += object[property];
}

You might have to add in object.hasOwnProperty if you modified the prototype.

import matplotlib.pyplot as plt  
plt.rcParams.update({'figure.max_open_warning': 0})

If you use this, you won’t get that error, and it is the simplest way to do that.

awk

awk '{gsub(/two.*/,"")}1' file

Ruby

ruby -ne 'print $_.gsub(/two.*/,"")' file

I have seen this before when people are trying to build a calendar. You want the cell linked but do not want to mess with anything else inside of it, try this and it might solve your problem.

<tr>
<td onClick="location.href='http://www.stackoverflow.com';">
Cell content goes here
</td>
</tr>

To do it in place, you can use the RemoveAll method of the "List<>" class along with a custom "Predicate" class...but all that does is clean up the code... under the hood it's doing the same thing you are...but yes, it does it in place, so you do same the temp list.

change the MaxClients directive. it is now on 256.

how to convert JTextField to string and string to JTextField in java

If you mean how to get and set String from jTextField then you can use following methods:

String str = jTextField.getText() // get string from jtextfield

and

jTextField.setText(str)  // set string to jtextfield
//or
new JTextField(str)     // set string to jtextfield

You should check JavaDoc for JTextField

It will already work, as David pointed out!

...         machine_epsilon = func(machine_epsilon) / func(2)
...     return machine_epsilon_last
...

You need to specify the std:: namespace:

std::cout << .... << std::endl;;

Alternatively, you can use a using directive:

using std::cout;
using std::endl;

cout << .... << endl;

I should add that you should avoid these using directives in headers, since code including these will also have the symbols brought into the global namespace. Restrict using directives to small scopes, for example

#include <iostream>

inline void foo()
{
  using std::cout;
  using std::endl;
  cout << "Hello world" << endl;
}

Here, the using directive only applies to the scope of foo().

Similar answer, but I just wanted to make it available for an easy/quick test.

var input = $("<input>")_x000D_
               .attr("name", "mydata").val("go Rafa!");_x000D_
_x000D_
$('#easy_test').append(input);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.3/jquery.min.js"></script>_x000D_
_x000D_
_x000D_
_x000D_
<form id="easy_test">_x000D_
  _x000D_
</form>

You can simply use json_encode function of php and save file with file handling functions such as fopen and fwrite.

The CASE statement is the closest to an IF statement in SQL, and is supported on all versions of SQL Server:

SELECT CASE <variable> 
           WHEN <value>      THEN <returnvalue> 
           WHEN <othervalue> THEN <returnthis> 
           ELSE <returndefaultcase> 
       END 
  FROM <table> 

If you are using eclipse and if you want force eclipse to re load dependencies you could try below command

gradlew clean cleaneclipse build eclipse --refresh-dependencies

DATE_FORMAT returns a string, so you're using two strings in your BETWEEN clause, which isn't going to work as you expect.

Instead, convert the date to your format in the SELECT and do the BETWEEN for the actual dates. For example,

SELECT DATE_FORMAT(create_date, '%m/%d/%y') as create_date_formatted
FROM table
WHERE create_date BETWEEN (CURDATE() - INTERVAL 30 DAY) AND CURDATE()

My recommendation is to use top location 33% or 25% from remaining space,
and not 50% as other examples posted here,
mainly because of the window header,
which look better and more comfort to the user,

complete code:

    <script language="javascript" type="text/javascript">
        function OpenPopupCenter(pageURL, title, w, h) {
            var left = (screen.width - w) / 2;
            var top = (screen.height - h) / 4;  // for 25% - devide by 4  |  for 33% - devide by 3
            var targetWin = window.open(pageURL, title, 'toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no, width=' + w + ', height=' + h + ', top=' + top + ', left=' + left);
        } 
    </script>
</head>
<body>
    <button onclick="OpenPopupCenter('http://www.google.com', 'TEST!?', 800, 600);">click on me</button>
</body>
</html>

check out this line:
var top = (screen.height - h) / 4; // for 25% - devide by 4 | for 33% - devide by 3

Compare value of phone2 with empty string:

select phone, phone2 
from jewishyellow.users 
where phone like '813%' and phone2<>''

Note that NULL value is interpreted as false.

You didn't bind all your bindings here

$sql = "SELECT SQL_CALC_FOUND_ROWS *, UNIX_TIMESTAMP(publicationDate) AS publicationDate     FROM comments WHERE articleid = :art 
ORDER BY " . mysqli_escape_string($order) . " LIMIT :numRows";

$st = $conn->prepare( $sql );
$st->bindValue( ":art", $art, PDO::PARAM_INT );

You've declared a binding called :numRows but you never actually bind anything to it.

UPDATE 2019: I keep getting upvotes on this and that reminded me of another suggestion

Double quotes are string interpolation in PHP, so if you're going to use variables in a double quotes string, it's pointless to use the concat operator. On the flip side, single quotes are not string interpolation, so if you've only got like one variable at the end of a string it can make sense, or just use it for the whole string.

In fact, there's a micro op available here since the interpreter doesn't care about parsing the string for variables. The boost is nearly unnoticable and totally ignorable on a small scale. However, in a very large application, especially good old legacy monoliths, there can be a noticeable performance increase if strings are used like this. (and IMO, it's easier to read anyway)

Put this bean in your configuration class.

 @Bean
  public Validator localValidatorFactoryBean() {
    return new LocalValidatorFactoryBean();
  }

and then You can use

 <T> BindingResult validate(T t) {
    DataBinder binder = new DataBinder(t);
    binder.setValidator(validator);
    binder.validate();
    return binder.getBindingResult();
}

for validating a bean manually. Then You will get all result in BindingResult and you can retrieve from there.

A couple of wires are crossed here. The various autoplay settings that you're working with only affect whether the SWF's root timeline starts out paused or not. So if your SWF had a timeline animation, or if it had an embedded video on the root timeline, then these settings would do what you're after.

However, the SWF you're working with almost certainly has only one frame on its timeline, so these settings won't affect playback at all. That one frame contains some flavor of video playback component, which contains ActionScript that controls how the video behaves. To get that player component to start of paused, you'll have to change the settings of the component itself.

Without knowing more about where the content came from it's hard to say more, but when one publishes from Flash, video player components normally include a parameter for whether to autoplay. If your SWF is being published by an application other than Flash (Captivate, I suppose, but I'm not up on that) then your best bet would be to check the settings for that app. Anyway it's not something you can control from the level of the HTML page. (Unless you were talking to the SWF from JavaScript, and for that to work the video component would have to be designed to allow it.)

TLS 1.2 is only supported since OpenSSL 1.0.1 (see the Major version releases section), you have to update your OpenSSL.

It is not necessary to set the CURLOPT_SSLVERSION option. The request involves a handshake which will apply the newest TLS version both server and client support. The server you request is using TLS 1.2, so your php_curl will use TLS 1.2 (by default) as well if your OpenSSL version is (or newer than) 1.0.1.

Im also suffered from this problem & simply, by adding port number after the ip address saved me.

$dsn = 'mysql:dbname=sms_messenger;host=127.0.0.1:8889';
$user = 'root';
$password = 'root';

This works for Mac OS

If you don't know your mysql port number, then
You can easily find the port number on MAMP home page

OR

Type following command while running the MAMP server to switch the terminal into mysql

OMBP:mamp Omal$ /Applications/MAMP/Library/bin/mysql --host=localhost -uroot -proot

Then type

mysql> SHOW GLOBAL VARIABLES LIKE 'PORT';

The last suggestion is the correct solution. Just to repeat, first set android:focusable="true" in the layout xml file, then requestFocus() on the view in your code.

I don't think a message box is the best way to go with this as you would need the VB code running in a loop to check the cell contents, or unless you plan to run the macro manually. In this case I think it would be better to add conditional formatting to the cell to change the background to red (for example) if the value exceeds the upper limit.

LPCWSTR stands for "Long Pointer to Constant Wide String". The W stands for Wide and means that the string is stored in a 2 byte character vs. the normal char. Common for any C/C++ code that has to deal with non-ASCII only strings.=

To get a normal C literal string to assign to a LPCWSTR, you need to prefix it with L

LPCWSTR a = L"TestWindow";
