This is happening because there is an unhandled exception in your Web service, and the .NET runtime is spitting out its HTML yellow screen of death server error/exception dump page, instead of XML.

Since the consumer of your Web service was expecting a text/xml header and instead got text/html, it throws that error.

You should address the cause of your timeouts (perhaps a lengthy SQL query?).

Also, checkout this blog post on Jeff Atwood's blog that explains implementing a global unhandled exception handler and using SOAP exceptions.

Not really. This is normally done using javascript.

there is a good discussion of ways of doing this here...

Autosizing textarea using Prototype

That would work depending on what client.get does when passed undefined as its first parameter.

Something like this would be safer:

app.get('/:key?', function(req, res, next) {
    var key = req.params.key;
    if (!key) {
        next();
        return;
    }
    client.get(key, function(err, reply) {
        if(client.get(reply)) {
            res.redirect(reply);
        }
        else {
            res.render('index', {
                link: null
            });
        }
    });
});

There's no problem in calling next() inside the callback.

According to this, handlers are invoked in the order that they are added, so as long as your next route is app.get('/', ...) it will be called if there is no key.

As everything is inside a string, external string variables being substituted in will need to be escaped and quoted twice. Using dollar quoting instead will not give full protection against SQL injection.

Most probably it has to do with caching on the device. Catching the exception and ignoring is not nice but my problem was fixed and it seems to work.

Implicit and Explicit Waits

Implicit Wait

An implicit wait is to tell WebDriver to poll the DOM for a certain amount of time when trying to find an element or elements if they are not immediately available. The default setting is 0. Once set, the implicit wait is set for the life of the WebDriver object instance.

driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);

Explicit Wait + Expected Conditions

An explicit waits is code you define to wait for a certain condition to occur before proceeding further in the code. The worst case of this is Thread.sleep(), which sets the condition to an exact time period to wait. There are some convenience methods provided that help you write code that will wait only as long as required. WebDriverWait in combination with ExpectedCondition is one way this can be accomplished.

WebDriverWait wait = new WebDriverWait(driver, 10);
WebElement element = wait.until(
        ExpectedConditions.visibilityOfElementLocated(By.id("someid")));

mplcursors worked for me. mplcursors provides clickable annotation for matplotlib. It is heavily inspired from mpldatacursor (https://github.com/joferkington/mpldatacursor), with a much simplified API

import matplotlib.pyplot as plt
import numpy as np
import mplcursors

data = np.outer(range(10), range(1, 5))

fig, ax = plt.subplots()
lines = ax.plot(data)
ax.set_title("Click somewhere on a line.\nRight-click to deselect.\n"
             "Annotations can be dragged.")

mplcursors.cursor(lines) # or just mplcursors.cursor()

plt.show()

An Example Using Your Own Data

You can avoid having your filename embedded in the NUMOFLINES variable by using redirection from JAVA_TAGS_FILE, rather than passing the filename as an argument to wc. For example:

NUMOFLINES=$(wc -l < "$JAVA_TAGS_FILE")

Explanation: Use Pipes or Redirection to Avoid Filenames in Output

The wc utility will not print the name of the file in its output if input is taken from a pipe or redirection operator. Consider these various examples:

# wc shows filename when the file is an argument
$ wc -l /etc/passwd
41 /etc/passwd

# filename is ignored when piped in on standard input
$ cat /etc/passwd | wc -l
41

# unusual redirection, but wc still ignores the filename
$ < /etc/passwd wc -l
41

# typical redirection, taking standard input from a file
$ wc -l < /etc/passwd
41

As you can see, the only time wc will print the filename is when its passed as an argument, rather than as data on standard input. In some cases, you may want the filename to be printed, so it's useful to understand when it will be displayed.

Here is an option for people who use DataBinding for RecyclerView. I have var recyclerViewState: Parcelable? in my adapter. And I use a BindingAdapter with a variation of @DawnYu's answer to set and update data in the RecyclerView:

@BindingAdapter("items")
fun setRecyclerViewItems(
    recyclerView: RecyclerView,
    items: List<RecyclerViewItem>?
) {
    var adapter = (recyclerView.adapter as? RecyclerViewAdapter)
    if (adapter == null) {
        adapter = RecyclerViewAdapter()
        recyclerView.adapter = adapter
    }

    adapter.recyclerViewState = recyclerView.layoutManager?.onSaveInstanceState()
    // the main idea is in this call with a lambda. It allows to avoid blinking on data update
    adapter.submitList(items.orEmpty()) {
        adapter.recyclerViewState?.let {
            recyclerView.layoutManager?.onRestoreInstanceState(it)
        }
    }
}

Finally, the XML part looks like:

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/possible_trips_rv"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    app:items="@{viewState.yourItems}"
    app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"/>

Node.JS to install a new version.

Step 1 : NVM Install

npm i -g nvm

Step 2 : NODE Newest version install

Finish

Once you understand full process running machinery in *unix, you will easily find simplier solution:

Consider this simple example how to make timeoutable communicate() meth using select.select() (available alsmost everythere on *nix nowadays). This also can be written with epoll/poll/kqueue, but select.select() variant could be a good example for you. And major limitations of select.select() (speed and 1024 max fds) are not applicapable for your task.

This works under *nix, does not create threads, does not uses signals, can be lauched from any thread (not only main), and fast enought to read 250mb/s of data from stdout on my machine (i5 2.3ghz).

There is a problem in join'ing stdout/stderr at the end of communicate. If you have huge program output this could lead to big memory usage. But you can call communicate() several times with smaller timeouts.

class Popen(subprocess.Popen):
    def communicate(self, input=None, timeout=None):
        if timeout is None:
            return subprocess.Popen.communicate(self, input)

        if self.stdin:
            # Flush stdio buffer, this might block if user
            # has been writing to .stdin in an uncontrolled
            # fashion.
            self.stdin.flush()
            if not input:
                self.stdin.close()

        read_set, write_set = [], []
        stdout = stderr = None

        if self.stdin and input:
            write_set.append(self.stdin)
        if self.stdout:
            read_set.append(self.stdout)
            stdout = []
        if self.stderr:
            read_set.append(self.stderr)
            stderr = []

        input_offset = 0
        deadline = time.time() + timeout

        while read_set or write_set:
            try:
                rlist, wlist, xlist = select.select(read_set, write_set, [], max(0, deadline - time.time()))
            except select.error as ex:
                if ex.args[0] == errno.EINTR:
                    continue
                raise

            if not (rlist or wlist):
                # Just break if timeout
                # Since we do not close stdout/stderr/stdin, we can call
                # communicate() several times reading data by smaller pieces.
                break

            if self.stdin in wlist:
                chunk = input[input_offset:input_offset + subprocess._PIPE_BUF]
                try:
                    bytes_written = os.write(self.stdin.fileno(), chunk)
                except OSError as ex:
                    if ex.errno == errno.EPIPE:
                        self.stdin.close()
                        write_set.remove(self.stdin)
                    else:
                        raise
                else:
                    input_offset += bytes_written
                    if input_offset >= len(input):
                        self.stdin.close()
                        write_set.remove(self.stdin)

            # Read stdout / stderr by 1024 bytes
            for fn, tgt in (
                (self.stdout, stdout),
                (self.stderr, stderr),
            ):
                if fn in rlist:
                    data = os.read(fn.fileno(), 1024)
                    if data == '':
                        fn.close()
                        read_set.remove(fn)
                    tgt.append(data)

        if stdout is not None:
            stdout = ''.join(stdout)
        if stderr is not None:
            stderr = ''.join(stderr)

        return (stdout, stderr)

CASE - 1

Run this command in your project..

php artisan --version  

You will get version of laravel installed in your system like this..

CASE - 2

Also you can check laravel version in the composer.json file in root directory.

I would avoid using SELECT *. Specify columns you actually want even though it may be all of them.

Yes, in my perspective there is no reason why you should write your own. Most of the Open Source BPM/Workflow frameworks are extremely flexible, you just need to learn the basics. If you choose jBPM you will get much more than a simple workflow engine, so it depends what are you trying to build.

I just ran a page of side by sides comparisons and unless something has changed recently, I could see no better downsizing (scaling) using canvas vs. simple css. I tested in FF6 Mac OSX 10.7. Still slightly soft vs. the original.

I did however stumble upon something that did make a huge difference and that was using image filters in browsers that support canvas. You can actually manipulate images much like you can in Photoshop with blur, sharpen, saturation, ripple, grayscale, etc.

I then found an awesome jQuery plug-in which makes application of these filters a snap: http://codecanyon.net/item/jsmanipulate-jquery-image-manipulation-plugin/428234

I simply apply the sharpen filter right after resizing the image which should give you the desired effect. I didn't even have to use a canvas element.

The main reason ++ comes in handy in C-like languages is for keeping track of indices. In Python, you deal with data in an abstract way and seldom increment through indices and such. The closest-in-spirit thing to ++ is the next method of iterators.

If your /tmp mount on a linux filesystem is mounted as overflow (often sized at 1MB), this is likely due to you not specifying /tmp as its own partition and your root filesystem filled up and /tmp was remounted as a fallback.

To fix this after you’ve cleared space, just unmount the fallback and it should remount at its original point:

sudo umount overflow

Pointers are similar to normal variables in that you don't need to delete them. They are removed from memory at the end of a functions execution and/or the end of the program.

You can however use pointers to allocate a 'block' of memory, for example like this:

int *some_integers = new int[20000]

This will allocate memory space for 20000 integers. Useful, because the Stack has a limited size and you might want to mess about with a big load of 'ints' without a stack overflow error.

Whenever you call new, you should then 'delete' at the end of your program, because otherwise you will get a memory leak, and some allocated memory space will never be returned for other programs to use. To do this:

delete [] some_integers;

Hope that helps.

It is the simplest one I could come up with, so wanted to share here,

#include<iostream.h>
#include<conio.h>
void main()
{
//clear the screen.
clrscr();
//declare variable type float
float cel, fah;
//Input the Temperature in given unit save them in ‘cel’
cout<<”Enter the Temperature in Celsius”<<endl;
cin>>cel;
//convert and save it in ‘fah’
fah=1.8*cel+32.0;
//show the output ‘fah’
cout<<”Temperature in Fahrenheit is “<<fah;
//get character
getch();
}

Source: Celsius to Fahrenheit

You can do it with something like this, so if no arguments are specified it will continue anyway:

public static void main(String[] args) {
    try {
        String one = args[0];
        String two = args[1];
    }
    catch (ArrayIndexOutOfBoundsException e){
        System.out.println("ArrayIndexOutOfBoundsException caught");
    }
    finally {

    }
}

And then launch the application:

java -jar myapp.jar arg1 arg2

public class MainActivity extends Activity {

private WebView webView1;
Button google; 


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    google = (Button) findViewById(R.id.google);
    google.setOnClickListener(new OnClickListener() {

        public void onClick(View arg0) {
            webView1 = (WebView) findViewById(R.id.webView);
            webView1.getSettings().setJavaScriptEnabled(true);
            webView1.loadUrl("http://www.google.co.in/");

      }
});        
    }

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

Is this something you are going to be doing a lot? If so, you may want to consider a different data structure. Grep is going to search the entire array every time and for a large array could be quite costly. If speed is an issue then you may want to consider using a Hash instead.

In your example, the key would be the number and the value would be the count of elements of that number.

This could be useful. Like another answer it is just CSS.

td {
    word-wrap: break-word;
}

For copy any text in Android:

            TextView text = findViewById(R.id.text_id);
            ImageView icons = findViewById(R.id.copy_icon);

            icons.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    ClipboardManager clipboardManager = (ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE);
                    ClipData clipData = ClipData.newPlainText("text whatever you want", text.getText().toString());
                    clipboardManager.setPrimaryClip(clipData);

                    Toast.makeText(context, "Text Copied", Toast.LENGTH_SHORT).show();
                }
            });

Here is how I did it. You can see how I convert the requestedURI to a filesystem path (what this SO question is about). Bonus: and also how to respond with the file.

@RequestMapping(value = "/file/{userId}/**", method = RequestMethod.GET)
public void serveFile(@PathVariable("userId") long userId, HttpServletRequest request, HttpServletResponse response) {
    assert request != null;
    assert response != null;

    // requestURL:  http://192.168.1.3:8080/file/54/documents/tutorial.pdf
    // requestURI:  /file/54/documents/tutorial.pdf
    // servletPath: /file/54/documents/tutorial.pdf
    // logger.debug("requestURL: " + request.getRequestURL());
    // logger.debug("requestURI: " + request.getRequestURI());
    // logger.debug("servletPath: " + request.getServletPath());

    String requestURI = request.getRequestURI();
    String relativePath = requestURI.replaceFirst("^/file/", "");

    Path path = Paths.get("/user_files").resolve(relativePath);
    try {
        InputStream is = new FileInputStream(path.toFile());  
        org.apache.commons.io.IOUtils.copy(is, response.getOutputStream());
        response.flushBuffer();
    } catch (IOException ex) {
        logger.error("Error writing file to output stream. Path: '" + path + "', requestURI: '" + requestURI + "'");
        throw new RuntimeException("IOError writing file to output stream");
    }
}

Sharing working and relevant code from our project:

//documentsArray is the list of sampleCollection objects
sampleCollection.insertMany(documentsArray)  
    .then((res) => {
        console.log("insert sampleCollection result ", res);
    })
    .catch(err => {
        console.log("bulk insert sampleCollection error ", err);
    });

<script>
function SetBack(dir) {
    document.getElementById('body').style.backgroundImage=dir;
}
SetBack('url(myniftybg.gif)');
</script>

You can do this, I am using

DataTable 1.10.5

using this code:

var versionNo = $.fn.dataTable.version;
alert(versionNo);

This is how I insert new record on my DataTable using row.add (My table has 10 columns), which can also includes HTML tag elements:

function fncInsertNew() {
            var table = $('#tblRecord').DataTable();

            table.row.add([
                    "Tiger Nixon",
                    "System Architect",
                    "$3,120",
                    "2011/04/25",
                    "Edinburgh",
                    "5421",
                    "Tiger Nixon",
                    "System Architect",
                    "$3,120",
                    "<p>Hello</p>"
            ]).draw();
        }

For multiple inserts at the same time, use rows.add instead:

var table = $('#tblRecord').DataTable();

table.rows.add( [ {
        "Tiger Nixon",
        "System Architect",
        "$3,120",
        "2011/04/25",
        "Edinburgh",
        "5421"
    }, {
        "Garrett Winters",
        "Director",
        "$5,300",
        "2011/07/25",
        "Edinburgh",
        "8422"
    }]).draw();

As a variation of Bridge's answer (I don't yet have enough rep to comment, and didn't feel right about editing that answer), here is a version that works better for me.

SELECT column_name AS [Name],
   IS_NULLABLE AS [Null?],
   DATA_TYPE + CASE
                 WHEN CHARACTER_MAXIMUM_LENGTH IS NULL THEN ''
                 WHEN CHARACTER_MAXIMUM_LENGTH > 99999 THEN ''
                 ELSE '(' + Cast(CHARACTER_MAXIMUM_LENGTH AS VARCHAR(5)) + ')' 
               END AS [Type]
FROM   INFORMATION_SCHEMA.Columns
WHERE  table_name = 'table_name'

Notable changes:

• Works for types without length. For an int column, I was seeing NULL for the type because the length was null and it wiped out the whole Type column. So don't print any length component (or parens).
• Change the check for CAST length of -1 to check actual length. I was getting a syntax error because the case resulted in '*' rather than -1. Seems to make more sense to perform an arithmetic check rather than an overflow from the CAST.
• Don't print length when very long (arbitrarily > 5 digits).

1. Add a key in your info.plist file UIViewControllerBasedStatusBarAppearance and set it to YES.

2. In viewDidLoad method of your ViewController add a method call:

   [self setNeedsStatusBarAppearanceUpdate];
   

3. Then paste the following method in viewController file:

   - (UIStatusBarStyle)preferredStatusBarStyle
   { 
       return UIStatusBarStyleLightContent; 
   }
   

Another way to go

const data: {[key: string]: any} = require('./data.json');

This was you still can define json type is you want and don't have to use wildcard.

For example, custom type json.

interface User {
  firstName: string;
  lastName: string;
  birthday: Date;
}
const user: User = require('./user.json');

If you are using TypeScript and don't want to account for "values those are false" then this is the solution for you:

First: import { isNullOrUndefined } from 'util';

Then: isNullOrUndefined(this.yourVariableName)

Please Note: As mentioned below this is now deprecated, use value === undefined || value === null instead. ref.

Here is a good tutorial with code. Let me know if it works for you! This is also a good tutorial.

EDIT

In This example, all you need to do is add this line:

gallery.setSelection(1);

after setting the adapter to gallery object, that is this line:

gallery.setAdapter(new ImageAdapter(this));

UPDATE1

Alright, I got your problem. This open source library is your solution. I also have used it for one of my projects. Hope this will solve your problem finally.

UPDATE2:

I would suggest you to go through this tutorial. You might get idea. I think I got your problem, you want the horizontal scrollview with snap. Try to search with that keyword on google or out here, you might get your solution.

For me the solution was to go into (on Windows 8.1):

System > Advanced system setting > Environment Variables 

Under 'System variables' in the 'Path' variable there was the following first:

C:\ProgramData\Oracle\Java\javapath;

I removed this and Eclipse worked again!

I like to keep the original array and return a copy. This is a generic version:

public static <T> T[] reverse(T[] array) {
    T[] copy = array.clone();
    Collections.reverse(Arrays.asList(copy));
    return copy;
}

without keeping the original array:

public static <T> void reverse(T[] array) {
    Collections.reverse(Arrays.asList(array));
}

You can do this easily manually for each column like this:

df['A_perc'] = df['A']/df['sum']

If you want to do this in one step for all columns, you can use the div method (http://pandas.pydata.org/pandas-docs/stable/basics.html#matching-broadcasting-behavior):

ds.div(ds['sum'], axis=0)

And if you want this in one step added to the same dataframe:

>>> ds.join(ds.div(ds['sum'], axis=0), rsuffix='_perc')
          A         B         C         D       sum    A_perc    B_perc  \
1  0.151722  0.935917  1.033526  0.941962  3.063127  0.049532  0.305543

What worked for me was to create DialogFragment an set it to not be cancelable:

dialog.setCancelable(false);

Clearing Cache solved the issue for me or you can open it in another browser

index.js

function myFun() {

It`s worked!

Alt + Shift + F10 will show the menu associated with the smart tag.

If you have tried all of this and still no luck, try the detach/attach again.

You can have many java versions in your system.

I think you should add the java 8 in yours JREs installed or edit.

Take a look my screen:

If you click in edit (check your java 8 path):

Take a look at "Literal String Interpolation" https://www.python.org/dev/peps/pep-0498/

I found it through the http://www.malemburg.com/

You can also Navigate to HTML id from inside controller

$location.hash('id_in_html');

Well i have the same problem, my way to fix it was to stop and disable the "application experience" service in Windows.

Well:

• It's not clear why you've got two methods with the same signature. What are they meant to accomplish?
• In the first method, why are you testing for testing for a single space or any single character?
• You might want to consider generalizing your termination condition to "if the length is less than two"
• Consider how you want to recurse. One option:
  • Check that the first letter is equal to the last letter. If not, return false
  • Now take a substring to effectively remove the first and last letters, and recurse
• Is this meant to be an exercise in recursion? That's certainly one way of doing it, but it's far from the only way.

I'm not going to spell it out any more clearly than that for the moment, because I suspect this is homework - indeed some may consider the help above as too much (I'm certainly slightly hesitant myself). If you have any problems with the above hints, update your question to show how far you've got.

yes it's possible to print a string to the console.

#include "stdafx.h"
#include <string>
#include <iostream>

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
    string strMytestString("hello world");
    cout << strMytestString;
    return 0;
}

stdafx.h isn't pertinent to the solution, everything else is.

It seems your makefile's name is not 'Makefile' or 'makefile'. In case it is different say 'abc' try running 'make -f abc clean'

You can stash (save the changes in temporary box) then, back to master branch HEAD.

$ git add .
$ git stash
$ git checkout master

Jump Over Commits Back and Forth:

• Go to a specific commit-sha.

    $ git checkout <commit-sha>
  

• If you have uncommitted changes here then, you can checkout to a new branch | Add | Commit | Push the current branch to the remote.

    # checkout a new branch, add, commit, push
    $ git checkout -b <branch-name>
    $ git add .
    $ git commit -m 'Commit message'
    $ git push origin HEAD          # push the current branch to remote 
  
    $ git checkout master           # back to master branch now
  

• If you have changes in the specific commit and don't want to keep the changes, you can do stash or reset then checkout to master (or, any other branch).

    # stash
    $ git add -A
    $ git stash
    $ git checkout master
  
    # reset
    $ git reset --hard HEAD
    $ git checkout master
  

• After checking out a specific commit if you have no uncommitted change(s) then, just back to master or other branch.

    $ git status          # see the changes
    $ git checkout master
  
    # or, shortcut
    $ git checkout -      # back to the previous state
  

Reasons of this error could be multiples but in my case i updated branch with root then when i tried to update it with normal user it gives me error .

try both solutions one should work for you

1- sudo chmod g+w .git -R

if it doesn't work please try next solution hope it will solve your problem

2 - rm -f .git/FETCH_HEAD

You can use one-line heredoc

cat <<< "This is coming from the stdin"

the above is the same as

cat <<EOF
This is coming from the stdin
EOF

or you can redirect output from a command, like

diff <(ls /bin) <(ls /usr/bin)

or you can read as

while read line
do
   echo =$line=
done < some_file

or simply

echo something | read param

Following the instructions from this page,

1. Open the XAMPP control panel (cmd-space, then enter manager-osx.app).
2. Select Manage Servers tab -> select Apache Web Server -> click Configure.
3. Click Open Conf File. Provide credentials if asked.

4. Change

   <IfModule unixd_module>
   #
   # If you wish httpd to run as a different user or group, you must run
   # httpd as root initially and it will switch.  
   #
   # User/Group: The name (or #number) of the user/group to run httpd as.
   # It is usually good practice to create a dedicated user and group for
   # running httpd, as with most system services.
   #
   User daemon
   Group daemon
   </IfModule>
   

   to

   <IfModule unixd_module>
   #
   # If you wish httpd to run as a different user or group, you must run
   # httpd as root initially and it will switch.  
   #
   # User/Group: The name (or #number) of the user/group to run httpd as.
   # It is usually good practice to create a dedicated user and group for
   # running httpd, as with most system services.
   #
   User your_username
   Group staff
   </IfModule>
   

5. Save and close.

6. Using the XAMPP control panel, restart Apache.

7. Navigate to the document root of your server and make yourself the owner. The default is /Applications/XAMPP/xamppfiles/htdocs.

   $ cd your_document_root
   $ sudo chown -R your_username:staff .
   

8. Navigate to the xamppfiles directory and change the permission for logs and temp directory.

   $ cd /Applications/XAMPP/xamppfiles
   $ sudo chown -R your_username:staff logs
   $ sudo chown -R your_username:staff temp
   

9. To be able to use phpmyadmin you have to change the permissions for config.inc.php.

   $ cd /Applications/XAMPP/xamppfiles/phpmyadmin
   $ sudo chown your_username:staff config.inc.php
   

If your OS is Unix base use this code:

import os
def check_process(name):
    output = []
    cmd = "ps -aef | grep -i '%s' | grep -v 'grep' | awk '{ print $2 }' > /tmp/out"
    os.system(cmd % name)
    with open('/tmp/out', 'r') as f:
        line = f.readline()
        while line:
            output.append(line.strip())
            line = f.readline()
            if line.strip():
                output.append(line.strip())

    return output

Then call it and pass it a process name to get all PIDs.

>>> check_process('firefox')
['499', '621', '623', '630', '11733']

Instead of overriding the library search path at runtime with LD_LIBRARY_PATH, you could instead bake it into the binary itself with rpath. If you link with GCC adding -Wl,-rpath,<libdir> should do the trick, if you link with ld it's just -rpath <libdir>.

In perl:

if($testString =~ /\d/) 
{
    print "This string contains at least one digit"
}

where \d matches to a digit.

Add maven directory /bin to System variables under the name Path.

To check this, you can echo %PATH%

Here's the config for ISAPI_Rewrite 3:

RewriteBase /

RewriteCond %{HTTP_HOST} ^mysite.org.uk$ [NC]

RewriteRule ^stuff/(.+)$ http://stuff.mysite.org.uk/$1 [NC,R=301,L]

I had the same problem, all you need to do is define classpath environment variable for tomcat, you can do it by adding a file, in my case C:\apache-tomcat-7.0.30\bin\setenv.bat, containing:

set "CLASSPATH=%CLASSPATH%;%CATALINA_HOME%\lib\mysql-connector-java-5.1.14-bin.jar"

then code, in my case:

Class.forName("com.mysql.jdbc.Driver").newInstance(); 
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/database_name", "root", "");

works fine.

You can add the SVG as background-image of an empty :after or :before.

Here you go:

.anchor:before {
  display: block;
  content: ' ';
  background-image: url('../images/anchor.svg');
  background-size: 28px 28px;
  height: 28px;
  width: 28px;
}

function getAge(birthday) {
    var today = new Date();
    var thisYear = 0;
    if (today.getMonth() < birthday.getMonth()) {
        thisYear = 1;
    } else if ((today.getMonth() == birthday.getMonth()) && today.getDate() < birthday.getDate()) {
        thisYear = 1;
    }
    var age = today.getFullYear() - birthday.getFullYear() - thisYear;
    return age;
}

Typically, iterators are used to access elements of a container in linear fashion; however, with "random access iterators", it is possible to access any element in the same fashion as operator[].

To access arbitrary elements in a vector vec, you can use the following:

vec.begin()                  // 1st
vec.begin()+1                // 2nd
// ...
vec.begin()+(i-1)            // ith
// ...
vec.begin()+(vec.size()-1)   // last

The following is an example of a typical access pattern (earlier versions of C++):

int sum = 0;
using Iter = std::vector<int>::const_iterator;
for (Iter it = vec.begin(); it!=vec.end(); ++it) {
    sum += *it;
}

The advantage of using iterator is that you can apply the same pattern with other containers:

sum = 0;
for (Iter it = lst.begin(); it!=lst.end(); ++it) {
    sum += *it;
}

For this reason, it is really easy to create template code that will work the same regardless of the container type. Another advantage of iterators is that it doesn't assume the data is resident in memory; for example, one could create a forward iterator that can read data from an input stream, or that simply generates data on the fly (e.g. a range or random number generator).

Another option using std::for_each and lambdas:

sum = 0;
std::for_each(vec.begin(), vec.end(), [&sum](int i) { sum += i; });

Since C++11 you can use auto to avoid specifying a very long, complicated type name of the iterator as seen before (or even more complex):

sum = 0;
for (auto it = vec.begin(); it!=vec.end(); ++it) {
    sum += *it;
}

And, in addition, there is a simpler for-each variant:

sum = 0;
for (auto value : vec) {
    sum += value;
}

And finally there is also std::accumulate where you have to be careful whether you are adding integer or floating point numbers.

See jsocket. Haven't used it myself. Been more than 3 years since last update (as of 26/6/2014).

* Uses flash :(

From the documentation:

<script type='text/javascript'>
    // Host we are connecting to
    var host = 'localhost'; 
    // Port we are connecting on
    var port = 3000;

    var socket = new jSocket();

    // When the socket is added the to document 
    socket.onReady = function(){
            socket.connect(host, port);             
    }

    // Connection attempt finished
    socket.onConnect = function(success, msg){
            if(success){
                    // Send something to the socket
                    socket.write('Hello world');            
            }else{
                    alert('Connection to the server could not be estabilished: ' + msg);            
            }       
    }
    socket.onData = function(data){
            alert('Received from socket: '+data);   
    }

    // Setup our socket in the div with the id="socket"
    socket.setup('mySocket');       
</script>

I wrote a working CodePen example to demonstrate a great way of filtering numeric user input. The directive currently only allows positive integers, but the regex can easily be updated to support any desired numeric format.

My directive is easy to use:

<input type="text" ng-model="employee.age" valid-number />

The directive is very easy to understand:

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

app.controller('MainCtrl', function($scope) {
});

app.directive('validNumber', function() {
  return {
    require: '?ngModel',
    link: function(scope, element, attrs, ngModelCtrl) {
      if(!ngModelCtrl) {
        return; 
      }

      ngModelCtrl.$parsers.push(function(val) {
        if (angular.isUndefined(val)) {
            var val = '';
        }
        var clean = val.replace( /[^0-9]+/g, '');
        if (val !== clean) {
          ngModelCtrl.$setViewValue(clean);
          ngModelCtrl.$render();
        }
        return clean;
      });

      element.bind('keypress', function(event) {
        if(event.keyCode === 32) {
          event.preventDefault();
        }
      });
    }
  };
});

I want to emphasize that keeping model references out of the directive is important.

I hope you find this helpful.

Big thanks to Sean Christe and Chris Grimes for introducing me to the ngModelController

I came up with this:

import re

regex = re.compile("[A-Za-z]") # find a alpha
str = "1st str"
s = regex.search(str).group() # find the first alpha
str = str.replace(s, s.upper(), 1) # replace only 1 instance
print str

just run your xammp as an administrator, it works

For me it works like this:

    options : {
      scales: {
        yAxes: [{
          scaleLabel: {
            display: true,
            labelString: 'probability'
          }
        }]
      }
    }

An old thread, but...Answer of Konerak works, but why would you even set size of a container by default. What I prefer is to use code wherever no matter of hog big page size is. So this my code:

<style>
   #container {
    position: relative;
    height: 100%;
 }
 #footer {
    position: absolute;
    bottom: 0;
 }
</style>

</HEAD>

<BODY>

 <div id="container">

    <h1>Some heading</h1>

<p>Some text you have</p> 

<br>
<br>

<div id="footer"><p>Rights reserved</p></div>

</div>

</BODY>
</HTML>

The trick is in <br> where you break new line. So, when page is small you'll see footer at bottom of page, as you want.

BUT, when a page is big SO THAT YOU MUST SCROLL IT DOWN, then your footer is going to be 2 new lines under the whole content above. And If you will then make page bigger, your footer is allways going to go DOWN. I hope somebody will find this useful.

I was also getting same error because of using & character directly in layout xml. So, please be careful about using html entities in your project.

Here is a working connection string for someone who needs reference.

  <connectionStrings>
    <add name="IdentityConnection" connectionString="Data Source=(LocalDb)\v11.0;AttachDbFilename=|DataDirectory|\IdentityDb.mdf;Integrated Security=True;MultipleActiveResultSets=true;" providerName="System.Data.SqlClient" />
  </connectionStrings>

I realize this was long ago answered but want to suggest an additional approach that avoids the nested try-with-resources double block.

public List<User> getUser(int userId) {
    try (Connection con = DriverManager.getConnection(myConnectionURL);
         PreparedStatement ps = createPreparedStatement(con, userId); 
         ResultSet rs = ps.executeQuery()) {

         // process the resultset here, all resources will be cleaned up

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

private PreparedStatement createPreparedStatement(Connection con, int userId) throws SQLException {
    String sql = "SELECT id, username FROM users WHERE id = ?";
    PreparedStatement ps = con.prepareStatement(sql);
    ps.setInt(1, userId);
    return ps;
}

Swift 4

Conform to UITextFieldDelegate.

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
    // figure out what the new string will be after the pending edit
    let updatedString = (textField.text as NSString?)?.replacingCharacters(in: range, with: string)

    // Do whatever you want here


    // Return true so that the change happens
    return true
}

word-break: normal seems better to use than word-break: break-word because break-word breaks initials such as EN

word-break: normal

You need to re-factor the code into pieces. This doesn't stop execution, it just puts a delay in between the parts.

function partA() {
  ...
  window.setTimeout(partB,1000);
}

function partB() {
   ...
}

In Swift 4, just as simple as Swift 3:

self.view.backgroundColor = UIColor.brown

You can update a metadata annotation that is not relevant for your deployment. it will trigger a rolling-update

for example:

    spec:
      template:
        metadata:
          annotations:
            configmap-version: 1

It looks like you are trying to connect using TLSv1.2, which isn't widely implemented on servers. Does your destination support tls1.2?

int means interrupt, and the number 0x80 is the interrupt number. An interrupt transfers the program flow to whomever is handling that interrupt, which is interrupt 0x80 in this case. In Linux, 0x80 interrupt handler is the kernel, and is used to make system calls to the kernel by other programs.

The kernel is notified about which system call the program wants to make, by examining the value in the register %eax (AT&T syntax, and EAX in Intel syntax). Each system call have different requirements about the use of the other registers. For example, a value of 1 in %eax means a system call of exit(), and the value in %ebx holds the value of the status code for exit().

Just to complete the answer above that use .Net.

In this code the path is stored in the %1 argument (which is written in the registry under quote that are escaped: \"%1\" ). To retrieve it, we need the $arg (inbuilt arg). Don't forget the quote around $FilePath.

# Get the File path:  
$FilePath = $args
Write-Host "FilePath: " $FilePath

# Get the complete file name:
$file_name_complete = [System.IO.Path]::GetFileName("$FilePath")
Write-Host "fileNameFull :" $file_name_complete

# Get File Name Without Extension:
$fileNameOnly = [System.IO.Path]::GetFileNameWithoutExtension("$FilePath")
Write-Host "fileNameOnly :" $fileNameOnly

# Get the Extension:
$fileExtensionOnly = [System.IO.Path]::GetExtension("$FilePath")
Write-Host "fileExtensionOnly :" $fileExtensionOnly

Use the built-in time keyword:

$ help time

time: time [-p] PIPELINE
    Execute PIPELINE and print a summary of the real time, user CPU time,
    and system CPU time spent executing PIPELINE when it terminates.
    The return status is the return status of PIPELINE.  The `-p' option
    prints the timing summary in a slightly different format.  This uses
    the value of the TIMEFORMAT variable as the output format.

Example:

$ time sleep 2

real    0m2.009s
user    0m0.000s
sys     0m0.004s

I struggled with the same issue when trying to feed floats to the classifiers. I wanted to keep floats and not integers for accuracy. Try using regressor algorithms. For example:

import numpy as np
from sklearn import linear_model
from sklearn import svm

classifiers = [
    svm.SVR(),
    linear_model.SGDRegressor(),
    linear_model.BayesianRidge(),
    linear_model.LassoLars(),
    linear_model.ARDRegression(),
    linear_model.PassiveAggressiveRegressor(),
    linear_model.TheilSenRegressor(),
    linear_model.LinearRegression()]

trainingData    = np.array([ [2.3, 4.3, 2.5],  [1.3, 5.2, 5.2],  [3.3, 2.9, 0.8],  [3.1, 4.3, 4.0]  ])
trainingScores  = np.array( [3.4, 7.5, 4.5, 1.6] )
predictionData  = np.array([ [2.5, 2.4, 2.7],  [2.7, 3.2, 1.2] ])

for item in classifiers:
    print(item)
    clf = item
    clf.fit(trainingData, trainingScores)
    print(clf.predict(predictionData),'\n')

It sounds like you want an image button:

<input type="image" src="logg.png" name="saveForm" class="btTxt submit" id="saveForm" />

Alternatively, you can use CSS to make the existing submit button use your image as its background.

In any case, you don't want a separate <img /> element on the page.

For quick steps just check summary. If interested to know details, go on to read below.

adb is a daemon. Doing ps adb we can see its process.

shell@grouper:/ $ ps adb
USER     PID   PPID  VSIZE  RSS     WCHAN    PC        NAME
shell     133   1     4636   212   ffffffff 00000000 S /sbin/adbd

I just checked what additional property variables it is using when adb is running as root and user.

adb user mode :

shell@grouper:/ $ getprop | grep adb                                         
[init.svc.adbd]: [running]
[persist.sys.usb.config]: [mtp,adb]
[ro.adb.secure]: [1]
[sys.usb.config]: [mtp,adb]
[sys.usb.state]: [mtp,adb]

adb root mode :

shell@grouper:/ # getprop | grep adb                                         
[init.svc.adbd]: [running]
[persist.sys.usb.config]: [mtp,adb]
[ro.adb.secure]: [1]
[service.adb.root]: [1]
[sys.usb.config]: [mtp,adb]
[sys.usb.state]: [mtp,adb]

We can see that service.adb.root is a new prop variable that came up when we did adb root.

So, to change back adb to user from root, I went ahead and made this 0

setprop service.adb.root 0

But this did not change anything.

Then I went ahead and killed the process (with an intention to restart the process). The pid of adbd process in my device is 133

kill -9 133

I exited from shell automatically after I had killed the process.

I did adb shell again it was in user mode.

SUMMARY :

So, we have 3 very simple steps.

1. Enter adb shell as a root.
2. setprop service.adb.root 0
3. kill -9 (pid of adbd)

After these steps just re-enter the shell with adb shell and you are back on your device as a user.

If you just happen to have a Map with Integer keys you cannot change, you could write a custom EL function to convert a Long to Integer. This would allow you to do something like:

<c:out value="${map[myLib:longToInteger(1)]}"/>

Try one of these two methods:

string get_file_string(){
    std::ifstream ifs("path_to_file");
    return string((std::istreambuf_iterator<char>(ifs)),
                  (std::istreambuf_iterator<char>()));
}

string get_file_string2(){
    ifstream inFile;
    inFile.open("path_to_file");//open the input file

    stringstream strStream;
    strStream << inFile.rdbuf();//read the file
    return strStream.str();//str holds the content of the file
}

Off hand, setting the http.agent system property to "" might do the trick (I don't have the code in front of me).

You might get away with:

 System.setProperty("http.agent", "");

but that might require a race between you and initialisation of the URL protocol handler, if it caches the value at startup (actually, I don't think it does).

The property can also be set through JNLP files (available to applets from 6u10) and on the command line:

-Dhttp.agent=

Or for wrapper commands:

-J-Dhttp.agent=

Box shadows can use commas to have multiple effects, just like with background images (in CSS3).

You can use Gson() (com.google.gson) library if you find any difficulty using Jackson.

HashMap<String, Object> yourHashMap = new Gson().fromJson(yourJsonObject.toString(), HashMap.class);

Setting height to 101% is my solution to the problem. You pages will no longer 'flick' when switching between ones that exceed the viewport height and ones that do not.

In your main styles.css file change height/auto to whatever settings you desire. For example, 500px:

#myCarousel {
  height: auto;
  width: auto;
  overflow: hidden;
}

userType = (user.Type == 0) ? "Admin" : (user.type == 1) ? "User" : "Admin";

should do the trick.

Similar to manojlds but includes the optional negative/positive numbers:

var regex = /^[-+]?\d+$/;

EDIT

If you don't want to allow zeros in the front (023 becomes invalid), you could write it this way:

var regex = /^[-+]?[1-9]\d*$/;

EDIT 2

As @DmitriyLezhnev pointed out, if you want to allow the number 0 to be valid by itself but still invalid when in front of other numbers (example: 0 is valid, but 023 is invalid). Then you could use

var regex = /^([+-]?[1-9]\d*|0)$/

Add These two lines in your text

As in my personal experience I found that very similar thing to Vikas Dwivedi answer will work just fine.

Step 1 (php.ini file)

In php.ini file located in xampp\php\php.ini. Change settings to the following:

 extension=php_openssl.dll
 [mail function]
 sendmail_path =":\xampp7\sendmail\sendmail.exe -t"
 mail.add_x_header=On

Turn off other variables under mail funciton by putting ; before them. e.g ;smtp_port=25

Step 2 (sendmail.ini file)

In sendmail.ini located in xampp\sendmail\semdmail.ini change to the following:

 smtp_server=smtp.gmail.com
 smtp_port=465
 smtp_ssl=auto
 [email protected]
 auth_password=YourPassword

Step 3 (code)

Create a php file and use the following:

 <?php
    mail($to, "subject", "body", "From: ".$from);
 ?>

Notice

• You need to restart apache in order for php.ini to reload.
• you need to activate Google Less secure app access in https://myaccount.google.com/u/1/security
• It might help to run Xampp with Admin permission.

Here is one trick:

public static int getItself(int itself, int dummy)
{
    return itself;
}

public static void main(String[] args)
{
    int a = 10;
    int b = 20;

    a = getItself(b, b = a);
}

If it can help someone, we have struggled a lot with Assetic, and we are now doing the following in development mode:

• Set up like in Dumping Asset Files in the dev Environmen so in config_dev.yml, we have commented:

  #assetic:
  #    use_controller: true
  

  And in routing_dev.yml

  #_assetic:
  #    resource: .
  #    type:     assetic
  

• Specify the URL as absolute from the web root. For example, background-image: url("/bundles/core/dynatree/skins/skin/vline.gif"); Note: our vhost web root is pointing on web/.

• No usage of cssrewrite filter

Following @JanKlimo example, on terminal all you have to do is:

to see all the Index: $ curl -XGET 'http://127.0.0.1:9200/_cat/indices?v'

to see content of Index products_development_20160517164519304: $ curl -XGET 'http://127.0.0.1:9200/products_development_20160517164519304/_search?pretty=1'

I had the same error here MacOSX 10.11 - it seems ruby checks to see if any directory (including the parents) in the path are world writable. In my case there wasn't a /usr/local/bin present as nothing had created it.

Run this command in your terminal.Try this sudo chmod 775 /usr/local After this if you have any password on your mac , then you have to enter the password . Now this issue will be fix.

I got the error message in the title from o.s.b.d.LoggingFailureAnalysisReporter along with the message "APPLICATION FAILED TO START". It turned out that I hadn't added -Dspring.profiles.active=dev to my Eclipse debug configuration so I had no active profile.

[ngStyle]="{'opacity': is_mail_sent ? '0.5' : '1' }"

@Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)

Given annotation worked for me. Can have a try

For Example :-

     public class Parent{
            @Id
            @GeneratedValue(strategy=GenerationType.AUTO)
            @Column(name="cct_id")
            private Integer cct_id;
            @OneToMany(cascade=CascadeType.REMOVE, fetch=FetchType.EAGER,mappedBy="clinicalCareTeam", orphanRemoval=true)
            @Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
            private List<Child> childs;
        }
            public class Child{
            @ManyToOne(fetch=FetchType.EAGER)
            @JoinColumn(name="cct_id")
            private Parent parent;
    }

Without a loop, just for the kicks of it...

You can either convert the array to a non-associative one, by doing:

$page = array_values($page);

And then acessing each element by it's zero-based index:

echo $page[0]; // 'index.html'
echo $page[1]; // 'services.html'

Or you can use a slightly more complicated version:

$value = array_slice($page, 0, 1);

echo key($value); // Home
echo current($value); // index.html

$value = array_slice($page, 1, 1);

echo key($value); // Service
echo current($value); // services.html

If you know the number of elements per "row" and the width of the container you can use a selector to add a margin to the elements you need to cause a justified look.

I had rows of three divs I wanted justified so used the:

.tile:nth-child(3n+2) { margin: 0 10px }

this allows the center div in each row to have a margin that forces the 1st and 3rd div to the outside edges of the container

Also great for other things like borders background colors etc

Use .map without return in simple way. Also start using let and const instead of var because let and const is more recommended

const rockets = [_x000D_
    { country:'Russia', launches:32 },_x000D_
    { country:'US', launches:23 },_x000D_
    { country:'China', launches:16 },_x000D_
    { country:'Europe(ESA)', launches:7 },_x000D_
    { country:'India', launches:4 },_x000D_
    { country:'Japan', launches:3 }_x000D_
];_x000D_
_x000D_
const launchOptimistic = rockets.map(elem => (_x000D_
  {_x000D_
    country: elem.country,_x000D_
    launches: elem.launches+10_x000D_
  } _x000D_
));_x000D_
_x000D_
console.log(launchOptimistic);

If I understand your question right:

To add a .net 2.0 Web Service Reference instead of a WCF Service Reference, right-click on your project and click 'Add Service Reference.'

Then click "Advanced.." at the bottom left of the dialog.

Then click "Add Web Reference.." on the bottom left of the next dialog.

Now you can add a regular SOAP web reference like you are looking for.

Another alternative is to use the ufunc.at. This method applies in-place a desired operation at specified indices. We can get the bin position for each datapoint using the searchsorted method. Then we can use at to increment by 1 the position of histogram at the index given by bin_indexes, every time we encounter an index at bin_indexes.

np.random.seed(1)
data = np.random.random(100) * 100
bins = np.linspace(0, 100, 10)

histogram = np.zeros_like(bins)

bin_indexes = np.searchsorted(bins, data)
np.add.at(histogram, bin_indexes, 1)

Have you tried the classic, waiting for the load to complete using jQuery's builtin ready function?

$(document).ready(function() {
    $('some selector', frames['nameOfMyIframe'].document).doStuff()
} );

Even if I know my compiler is smart enough, I won't like to rely on it, and will use the a) variant.

The b) variant makes sense to me only if you desperately need to make the intermediateResult unavailable after the loop body. But I can't imagine such desperate situation, anyway....

EDIT: Jon Skeet made a very good point, showing that variable declaration inside a loop can make an actual semantic difference.

I think you are looking for the Dictionary object, found in the Microsoft Scripting Runtime library. (Add a reference to your project from the Tools...References menu in the VBE.)

It pretty much works with any simple value that can fit in a variant (Keys can't be arrays, and trying to make them objects doesn't make much sense. See comment from @Nile below.):

Dim d As dictionary
Set d = New dictionary

d("x") = 42
d(42) = "forty-two"
d(CVErr(xlErrValue)) = "Excel #VALUE!"
Set d(101) = New Collection

You can also use the VBA Collection object if your needs are simpler and you just want string keys.

I don't know if either actually hashes on anything, so you might want to dig further if you need hashtable-like performance. (EDIT: Scripting.Dictionary does use a hash table internally.)

My answer is not to update the Google play service but work around. Get the play service version of the emulator by using the following code

getPackageManager().getPackageInfo("com.google.android.gms", 0 ).versionName);

For example if the value is "9.8.79" then use the nearest lesser version available com.google.android.gms:play-services:9.8.0'

This will resolve your problem. Get the release history from https://developers.google.com/android/guides/releases#november_2016_-_v100

Or try this:

apt-get install python-mysqldb

You can declare like one of the below options:

char data[] = "Testing String";

or

const char* data = "Testing String";

or

char* data = (char*) "Testing String";

my solution is :

static string GetPolyndrom(string str)
{
    string Longest = "";

    for (int i = 0; i < str.Length; i++)
    {
        if ((str.Length - 1 - i) < Longest.Length)
        {
            break;
        }
        for (int j = str.Length - 1; j > i; j--)
        {
            string str2 = str.Substring(i, j - i + 1);
            if (str2.Length > Longest.Length)
            {
                if (str2 == str2.Reverse())
                {
                    Longest = str2;
                }
            }
            else
            {
                break;
            }
        }

    }
    return Longest;
}

In Swift 2.0, the minElement and maxElement become methods of SequenceType protocol, you should call them like:

let a = [1, 2, 3]
print(a.maxElement()) //3
print(a.minElement()) //1

Using maxElement as a function like maxElement(a) is unavailable now.

The syntax of Swift is in flux, so I can just confirm this in Xcode version7 beta6.

It may be modified in the future, so I suggest that you'd better check the doc before you use these methods.

You can also use sponge from the moreutils package and not need to redirect the output (i.e., no tee noise to hide):

echo 'Add this line' | sudo sponge -a privfile

You need to subscribe to a SMS gateway. There are thousands of those (try searching with google) and they are usually not free. For example this one has support for PHP.

JSON.stringify(err, Object.getOwnPropertyNames(err))

seems to work

[from a comment by /u/ub3rgeek on /r/javascript] and felixfbecker's comment below

Like in other answers, start your span attributes with this:

display:inline-block;  

Now you can use padding more than width:

padding-left:6%;
padding-right:6%;

When you use padding, your color expands to both side (right and left), not just right (like in widht).

let's suppose the new and untracked file is called: "views.json". if you want to change branch by stashing the state of your app, I generally type:

And it would be stashed. Then I can just change branch with

git checkout other-nice-branch

• nesting SUBSTITUTE() in a string can be nasty, however, it's always possible to arrange it:

You can use FileChannel in Java.

FileChannel has the size() method to determine the size of the file.

    String fileName = "D://words.txt";

    Path filePath = Paths.get(fileName);

    FileChannel fileChannel = FileChannel.open(filePath);
    long fileSize = fileChannel.size();

    System.out.format("The size of the file: %d bytes", fileSize);

Or you can determine the file size using Apache Commons' FileUtils' sizeOf() method. If you are using maven, add this to pom.xml file.

<dependency>
    <groupId>commons-io</groupId>
    <artifactId>commons-io</artifactId>
    <version>2.6</version>
</dependency>

Try the following coding,

    String fileName = "D://words.txt";
    File f = new File(fileName);

    long fileSize = FileUtils.sizeOf(f);        

    System.out.format("The size of the file: %d bytes", fileSize);

These methods will output the size in Bytes. So to get the MB size, you need to divide the file size from (1024*1024).

Now you can simply use the if-else conditions since the size is captured in MB.

In Jackson 2.4, you can convert as follows:

MyClass newJsonNode = jsonObjectMapper.treeToValue(someJsonNode, MyClass.class);

where jsonObjectMapper is a Jackson ObjectMapper.

In older versions of Jackson, it would be

MyClass newJsonNode = jsonObjectMapper.readValue(someJsonNode, MyClass.class);

You can just compare the boolean array. For example

X = [True, False, True]

then

Y = X == False

would give you

Y = [False, True, False]

A flexible way to do it :
(Not made for current date but good enough for durations)

/**
convert duration to a ms/sec/min/hour/day/week array
@param {int}        msTime              : time in milliseconds 
@param {bool}       fillEmpty(optional) : fill array values even when they are 0.
@param {string[]}   suffixes(optional)  : add suffixes to returned values.
                                        values are filled with missings '0'
@return {int[]/string[]} : time values from higher to lower(ms) range.
*/
var msToTimeList=function(msTime,fillEmpty,suffixes){
    suffixes=(suffixes instanceof Array)?suffixes:[];   //suffixes is optional
    var timeSteps=[1000,60,60,24,7];    // time ranges : ms/sec/min/hour/day/week
    timeSteps.push(1000000);    //add very big time at the end to stop cutting
    var result=[];
    for(var i=0;(msTime>0||i<1||fillEmpty)&&i<timeSteps.length;i++){
        var timerange = msTime%timeSteps[i];
        if(typeof(suffixes[i])=="string"){
            timerange+=suffixes[i]; // add suffix (converting )
            // and fill zeros :
            while(  i<timeSteps.length-1 &&
                    timerange.length<((timeSteps[i]-1)+suffixes[i]).length  )
                timerange="0"+timerange;
        }
        result.unshift(timerange);  // stack time range from higher to lower
        msTime = Math.floor(msTime/timeSteps[i]);
    }
    return result;
};

NB : you could also set timeSteps as parameter if you want to control the time ranges.

how to use (copy an test):

var elsapsed = Math.floor(Math.random()*3000000000);

console.log(    "elsapsed (labels) = "+
        msToTimeList(elsapsed,false,["ms","sec","min","h","days","weeks"]).join("/")    );

console.log(    "half hour : "+msToTimeList(elsapsed,true)[3]<30?"first":"second"   );

console.log(    "elsapsed (classic) = "+
        msToTimeList(elsapsed,false,["","","","","",""]).join(" : ")    );

I changed the Office365 password and then tried to send a test email and it worked like a charm for me.

I used the front end (database mail option) and settings as smtp.office365.com port number 587 and checked the secure connection option. use basic authentication and store the credentials. Hope this turns out useful for someone.

Using a for loop, how do I access the loop index, from 1 to 5 in this case?

Use enumerate to get the index with the element as you iterate:

for index, item in enumerate(items):
    print(index, item)

And note that Python's indexes start at zero, so you would get 0 to 4 with the above. If you want the count, 1 to 5, do this:

for count, item in enumerate(items, start=1):
    print(count, item)

Unidiomatic control flow

What you are asking for is the Pythonic equivalent of the following, which is the algorithm most programmers of lower-level languages would use:

index = 0            # Python's indexing starts at zero
for item in items:   # Python's for loops are a "for each" loop 
    print(index, item)
    index += 1

Or in languages that do not have a for-each loop:

index = 0
while index < len(items):
    print(index, items[index])
    index += 1

or sometimes more commonly (but unidiomatically) found in Python:

for index in range(len(items)):
    print(index, items[index])

Use the Enumerate Function

Python's enumerate function reduces the visual clutter by hiding the accounting for the indexes, and encapsulating the iterable into another iterable (an enumerate object) that yields a two-item tuple of the index and the item that the original iterable would provide. That looks like this:

for index, item in enumerate(items, start=0):   # default is zero
    print(index, item)

This code sample is fairly well the canonical example of the difference between code that is idiomatic of Python and code that is not. Idiomatic code is sophisticated (but not complicated) Python, written in the way that it was intended to be used. Idiomatic code is expected by the designers of the language, which means that usually this code is not just more readable, but also more efficient.

Getting a count

Even if you don't need indexes as you go, but you need a count of the iterations (sometimes desirable) you can start with 1 and the final number will be your count.

for count, item in enumerate(items, start=1):   # default is zero
    print(item)

print('there were {0} items printed'.format(count))

The count seems to be more what you intend to ask for (as opposed to index) when you said you wanted from 1 to 5.

Breaking it down - a step by step explanation

To break these examples down, say we have a list of items that we want to iterate over with an index:

items = ['a', 'b', 'c', 'd', 'e']

Now we pass this iterable to enumerate, creating an enumerate object:

enumerate_object = enumerate(items) # the enumerate object

We can pull the first item out of this iterable that we would get in a loop with the next function:

iteration = next(enumerate_object) # first iteration from enumerate
print(iteration)

And we see we get a tuple of 0, the first index, and 'a', the first item:

(0, 'a')

we can use what is referred to as "sequence unpacking" to extract the elements from this two-tuple:

index, item = iteration
#   0,  'a' = (0, 'a') # essentially this.

and when we inspect index, we find it refers to the first index, 0, and item refers to the first item, 'a'.

>>> print(index)
0
>>> print(item)
a

Conclusion

• Python indexes start at zero
• To get these indexes from an iterable as you iterate over it, use the enumerate function
• Using enumerate in the idiomatic way (along with tuple unpacking) creates code that is more readable and maintainable:

So do this:

for index, item in enumerate(items, start=0):   # Python indexes start at zero
    print(index, item)

I know this is super old but after not finding the (pure CSS) answer I was looking for I came up with this solution (partially abstracted from medium.com) and thought it might help others looking to do the same thing.

If you combine @DuckMaestro's answers you can position an element fixed relative to a parent (actually grandparent). Use position: absolute; to position an element inside a parent with position: relative; and then position: fixed; on an element inside the absolute positioned element like so:

HTML

<div class="relative">
  <div class="absolute">
    <a class="fixed-feedback">This element will be fixed</a>
  </div>
</div>

CSS

.relative {
  margin: 0 auto;
  position: relative;
  width: 300px;
}

.absolute {
  position: absolute;
  right: 0;
  top: 0;
  width: 50px;
}

.fixed-feedback {
  position: fixed;
  top: 120px;
  width: 50px;
}

EXAMPLE

Like @JonAdams said, the definition of position: fixed requires the element to be positioned relative to the viewport but you can get around the horizontal aspect of that using this solution.

Note: This is different than just setting a right or left value on the fixed element because that would cause it to move horizontally when a window is resized.

Have a look on: http://www.cplusplus.com/reference/random/normal_distribution/. It's the simplest way to produce normal distributions.

This is my 2 cents based on Grax's answer, but with two parameters required for a generic method.

Assume your method is defined as follows in an Helpers class:

public class Helpers
{
    public static U ConvertCsvDataToCollection<U, T>(string csvData)
    where U : ObservableCollection<T>
    {
      //transform code here
    }
}

In my case, U type is always an observable collection storing object of type T.

As I have my types predefined, I first create the "dummy" objects that represent the observable collection (U) and the object stored in it (T) and that will be used below to get their type when calling the Make

object myCollection = Activator.CreateInstance(collectionType);
object myoObject = Activator.CreateInstance(objectType);

Then call the GetMethod to find your Generic function:

MethodInfo method = typeof(Helpers).
GetMethod("ConvertCsvDataToCollection");

So far, the above call is pretty much identical as to what was explained above but with a small difference when you need have to pass multiple parameters to it.

You need to pass an Type[] array to the MakeGenericMethod function that contains the "dummy" objects' types that were create above:

MethodInfo generic = method.MakeGenericMethod(
new Type[] {
   myCollection.GetType(),
   myObject.GetType()
});

Once that's done, you need to call the Invoke method as mentioned above.

generic.Invoke(null, new object[] { csvData });

And you're done. Works a charm!

UPDATE:

As @Bevan highlighted, I do not need to create an array when calling the MakeGenericMethod function as it takes in params and I do not need to create an object in order to get the types as I can just pass the types directly to this function. In my case, since I have the types predefined in another class, I simply changed my code to:

object myCollection = null;

MethodInfo method = typeof(Helpers).
GetMethod("ConvertCsvDataToCollection");

MethodInfo generic = method.MakeGenericMethod(
   myClassInfo.CollectionType,
   myClassInfo.ObjectType
);

myCollection = generic.Invoke(null, new object[] { csvData });

myClassInfo contains 2 properties of type Type which I set at run time based on an enum value passed to the constructor and will provide me with the relevant types which I then use in the MakeGenericMethod.

Thanks again for highlighting this @Bevan.

Introduction

After over 5 years since this question was asked there is only one correct answer by generalhenry but even though that answer has no problems with the code, it seems to have some problems with reception. It was commented that it "doesn't explain much other than how to rely on someone else to get the job done" and the fact how many people have voted this comment up clearly shows that a lot of things need clarification.

First of all, a good answer to "How to serve images using Node.js" is not implementing a static file server from scratch and doing it badly. A good answer is using a module like Express that does the job correctly.

Answering comments that say that using Express "doesn't explain much other than how to rely on someone else to get the job done" it should be noted, that using the http module already relies on someone else to get the job done. If someone doesn't want to rely on anyone to get the job done then at least raw TCP sockets should be used instead - which I do in one of my examples below.

A more serious problem is that all of the answers here that use the http module are broken. They introduce race conditions, insecure path resolution that will lead to path traversal vulnerability, blocking I/O that will completely fail to serve any concurrent requests at all and other subtle problems - they are completely broken as examples of what the question asks about, and yet they already use the abstraction that is provided by the http module instead of using TCP sockets so they don't even do everything from scratch as they claim.

If the question was "How to implement static file server from scratch, as a learning exercise" then by all means answers how to do that should be posted - but even then we should expect them to at least be correct. Also, it is not unreasonable to assume that someone who wants to serve an image might want to serve more images in the future so one could argue that writing a specific custom static file server that can serve only one single file with hard-coded path is somewhat shortsighted. It seems hard to imagine that anyone who searches for an answer on how to serve an image would be content with a solution that serves just a single image instead of a general solution to serve any image.

In short, the question is how to serve an image and an answer to that is to use an appropriate module to do that in a secure, preformant and reliable way that is readable, maintainable and future-proof while using the best practice of professional Node development. But I agree that a great addition to such an answer would be showing a way to implement the same functionality manually but sadly every attempt to do that has failed so far. And that is why I wrote some new examples.

After this short introduction, here are my five examples doing the job on 5 different levels of abstraction.

Minimum functionality

Every example serves files from the public directory and supports the minumum functionality of:

• MIME types for most common files
• serves HTML, JS, CSS, plain text and images
• serves index.html as a default directory index
• responds with error codes for missing files
• no path traversal vulnerabilities
• no race conditions while reading files

I tested every version on Node versions 4, 5, 6 and 7.

express.static

This version uses the express.static built-in middleware of the express module.

This example has the most functionality and the least amount of code.

var path = require('path');
var express = require('express');
var app = express();

var dir = path.join(__dirname, 'public');

app.use(express.static(dir));

app.listen(3000, function () {
    console.log('Listening on http://localhost:3000/');
});

express

This version uses the express module but without the express.static middleware. Serving static files is implemented as a single route handler using streams.

This example has simple path traversal countermeasures and supports a limited set of most common MIME types.

var path = require('path');
var express = require('express');
var app = express();
var fs = require('fs');

var dir = path.join(__dirname, 'public');

var mime = {
    html: 'text/html',
    txt: 'text/plain',
    css: 'text/css',
    gif: 'image/gif',
    jpg: 'image/jpeg',
    png: 'image/png',
    svg: 'image/svg+xml',
    js: 'application/javascript'
};

app.get('*', function (req, res) {
    var file = path.join(dir, req.path.replace(/\/$/, '/index.html'));
    if (file.indexOf(dir + path.sep) !== 0) {
        return res.status(403).end('Forbidden');
    }
    var type = mime[path.extname(file).slice(1)] || 'text/plain';
    var s = fs.createReadStream(file);
    s.on('open', function () {
        res.set('Content-Type', type);
        s.pipe(res);
    });
    s.on('error', function () {
        res.set('Content-Type', 'text/plain');
        res.status(404).end('Not found');
    });
});

app.listen(3000, function () {
    console.log('Listening on http://localhost:3000/');
});

connect

This version uses the connect module which is a one level of abstraction lower than express.

This example has similar functionality to the express version but using slightly lower-lever APIs.

var path = require('path');
var connect = require('connect');
var app = connect();
var fs = require('fs');

var dir = path.join(__dirname, 'public');

var mime = {
    html: 'text/html',
    txt: 'text/plain',
    css: 'text/css',
    gif: 'image/gif',
    jpg: 'image/jpeg',
    png: 'image/png',
    svg: 'image/svg+xml',
    js: 'application/javascript'
};

app.use(function (req, res) {
    var reqpath = req.url.toString().split('?')[0];
    if (req.method !== 'GET') {
        res.statusCode = 501;
        res.setHeader('Content-Type', 'text/plain');
        return res.end('Method not implemented');
    }
    var file = path.join(dir, reqpath.replace(/\/$/, '/index.html'));
    if (file.indexOf(dir + path.sep) !== 0) {
        res.statusCode = 403;
        res.setHeader('Content-Type', 'text/plain');
        return res.end('Forbidden');
    }
    var type = mime[path.extname(file).slice(1)] || 'text/plain';
    var s = fs.createReadStream(file);
    s.on('open', function () {
        res.setHeader('Content-Type', type);
        s.pipe(res);
    });
    s.on('error', function () {
        res.setHeader('Content-Type', 'text/plain');
        res.statusCode = 404;
        res.end('Not found');
    });
});

app.listen(3000, function () {
    console.log('Listening on http://localhost:3000/');
});

http

This version uses the http module which is the lowest-level API for HTTP in Node.

This example has similar functionality to the connect version but using even more lower-level APIs.

var path = require('path');
var http = require('http');
var fs = require('fs');

var dir = path.join(__dirname, 'public');

var mime = {
    html: 'text/html',
    txt: 'text/plain',
    css: 'text/css',
    gif: 'image/gif',
    jpg: 'image/jpeg',
    png: 'image/png',
    svg: 'image/svg+xml',
    js: 'application/javascript'
};

var server = http.createServer(function (req, res) {
    var reqpath = req.url.toString().split('?')[0];
    if (req.method !== 'GET') {
        res.statusCode = 501;
        res.setHeader('Content-Type', 'text/plain');
        return res.end('Method not implemented');
    }
    var file = path.join(dir, reqpath.replace(/\/$/, '/index.html'));
    if (file.indexOf(dir + path.sep) !== 0) {
        res.statusCode = 403;
        res.setHeader('Content-Type', 'text/plain');
        return res.end('Forbidden');
    }
    var type = mime[path.extname(file).slice(1)] || 'text/plain';
    var s = fs.createReadStream(file);
    s.on('open', function () {
        res.setHeader('Content-Type', type);
        s.pipe(res);
    });
    s.on('error', function () {
        res.setHeader('Content-Type', 'text/plain');
        res.statusCode = 404;
        res.end('Not found');
    });
});

server.listen(3000, function () {
    console.log('Listening on http://localhost:3000/');
});

net

This version uses the net module which is the lowest-level API for TCP sockets in Node.

This example has some of the functionality of the http version but the minimal and incomplete HTTP protocol has been implemented from scratch. Since it doesn't support chunked encoding it loads the files into memory before serving them to know the size before sending a response because statting the files and then loading would introduce a race condition.

var path = require('path');
var net = require('net');
var fs = require('fs');

var dir = path.join(__dirname, 'public');

var mime = {
    html: 'text/html',
    txt: 'text/plain',
    css: 'text/css',
    gif: 'image/gif',
    jpg: 'image/jpeg',
    png: 'image/png',
    svg: 'image/svg+xml',
    js: 'application/javascript'
};

var server = net.createServer(function (con) {
    var input = '';
    con.on('data', function (data) {
        input += data;
        if (input.match(/\n\r?\n\r?/)) {
            var line = input.split(/\n/)[0].split(' ');
            var method = line[0], url = line[1], pro = line[2];
            var reqpath = url.toString().split('?')[0];
            if (method !== 'GET') {
                var body = 'Method not implemented';
                con.write('HTTP/1.1 501 Not Implemented\n');
                con.write('Content-Type: text/plain\n');
                con.write('Content-Length: '+body.length+'\n\n');
                con.write(body);
                con.destroy();
                return;
            }
            var file = path.join(dir, reqpath.replace(/\/$/, '/index.html'));
            if (file.indexOf(dir + path.sep) !== 0) {
                var body = 'Forbidden';
                con.write('HTTP/1.1 403 Forbidden\n');
                con.write('Content-Type: text/plain\n');
                con.write('Content-Length: '+body.length+'\n\n');
                con.write(body);
                con.destroy();
                return;
            }
            var type = mime[path.extname(file).slice(1)] || 'text/plain';
            var s = fs.readFile(file, function (err, data) {
                if (err) {
                    var body = 'Not Found';
                    con.write('HTTP/1.1 404 Not Found\n');
                    con.write('Content-Type: text/plain\n');
                    con.write('Content-Length: '+body.length+'\n\n');
                    con.write(body);
                    con.destroy();
                } else {
                    con.write('HTTP/1.1 200 OK\n');
                    con.write('Content-Type: '+type+'\n');
                    con.write('Content-Length: '+data.byteLength+'\n\n');
                    con.write(data);
                    con.destroy();
                }
            });
        }
    });
});

server.listen(3000, function () {
    console.log('Listening on http://localhost:3000/');

To note it in the languages you mentioned:

Java:

String str = new String("Hello");

Python:

str = "Hello"

Both Java and Python have the concept of a "string", C does not have the concept of a "string". C has character arrays which can come in "read only" or manipulatable.

C:

char * str = "Hello";  // the string "Hello\0" is pointed to by the character pointer
                       // str. This "string" can not be modified (read only)

or

char str[] = "Hello";  // the characters: 'H''e''l''l''o''\0' have been copied to the 
                       // array str. You can change them via: str[x] = 't'

A character array is a sequence of contiguous characters with a unique sentinel character at the end (normally a NULL terminator '\0'). Note that the sentinel character is auto-magically appended for you in the cases above.

You can use urllib.parse.urljoin:

>>> from urllib.parse import urljoin
>>> urljoin('/media/path/', 'js/foo.js')
'/media/path/js/foo.js'

But beware:

>>> urljoin('/media/path', 'js/foo.js')
'/media/js/foo.js'
>>> urljoin('/media/path', '/js/foo.js')
'/js/foo.js'

The reason you get different results from /js/foo.js and js/foo.js is because the former begins with a slash which signifies that it already begins at the website root.

On Python 2, you have to do

from urlparse import urljoin

Just export the environment variables you want above the check for a non-interactive shell in ~/.bashrc.

I saw in getwindowtext (user32) on pinvoke.net that you can place a MarshalAs statement to state that the StringBuffer is equivalent to LPSTR.

<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Ansi)> _
Public Function GetWindowText(hwnd As IntPtr, <MarshalAs(UnManagedType.LPStr)>lpString As System.Text.StringBuilder, cch As Integer) As Integer
End Function

My personal view on a statement made earlier in this thread:

And just for fun:

On Error Resume Next is the devil incarnate and to be avoided, as it silently hides errors.

I'm using the On Error Resume Next on procedures where I don't want an error to stop my work and where any statement does not depend on the result of the previous statements.

When I'm doing this I add a global variable debugModeOn and I set it to True. Then I use it this way:

If not debugModeOn Then On Error Resume Next

When I deliver my work, I set the variable to false, thus hiding the errors only to the user and showing them during testing.

Also using it when doing something that may fail like calling the DataBodyRange of a ListObject that may be empty:

On Error Resume Next
Sheet1.ListObjects(1).DataBodyRange.Delete
On Error Goto 0

Instead of:

If Sheet1.ListObjects(1).ListRows.Count > 0 Then 
    Sheet1.ListObjects(1).DataBodyRange.Delete
End If

Or checking existence of an item in a collection:

On Error Resume Next
Err.Clear
Set auxiliarVar = collection(key)

' Check existence (if you try to retrieve a nonexistant key you get error number 5)
exists = (Err.Number <> 5)

You can not give order by because order by does a "full scan" on a table.

The following query is better:

SELECT * FROM table WHERE id = (SELECT MAX(id) FROM table);

you can use the DBMS_SQL.DESCRIBE_COLUMNS2

    SET SERVEROUTPUT ON;
DECLARE
    STMT CLOB;
    CUR NUMBER;
    COLCNT NUMBER;
    IDX NUMBER;
    COLDESC DBMS_SQL.DESC_TAB2;
BEGIN
    CUR := DBMS_SQL.OPEN_CURSOR;
    STMT := 'SELECT  object_name , to_char(object_id), created FROM    DBA_OBJECTS where rownum<10';

    SYS.DBMS_SQL.PARSE(CUR, STMT, DBMS_SQL.NATIVE);
    DBMS_SQL.DESCRIBE_COLUMNS2(CUR, COLCNT, COLDESC);
    DBMS_OUTPUT.PUT_LINE('Statement: ' || STMT);
    FOR IDX IN 1 .. COLCNT
    LOOP
        CASE COLDESC(IDX).col_type
        WHEN 2 THEN
            DBMS_OUTPUT.PUT_LINE('#' || TO_CHAR(IDX) || ': NUMBER');
        WHEN 12 THEN
            DBMS_OUTPUT.PUT_LINE('#' || TO_CHAR(IDX) || ': DATE');
        WHEN 180 THEN
            DBMS_OUTPUT.PUT_LINE('#' || TO_CHAR(IDX) || ': TIMESTAMP');
        WHEN 1 THEN
            DBMS_OUTPUT.PUT_LINE('#' || TO_CHAR(IDX) || ': VARCHAR'||':'|| COLDESC(IDX).col_max_len);
        WHEN 9 THEN
            DBMS_OUTPUT.PUT_LINE('#' || TO_CHAR(IDX) || ': VARCHAR2');
        -- Insert more cases if you need them
        ELSE
            DBMS_OUTPUT.PUT_LINE('#' || TO_CHAR(IDX) || ': OTHERS (' || TO_CHAR(COLDESC(IDX).col_type) || ')');
        END CASE;
    END LOOP;
    SYS.DBMS_SQL.CLOSE_CURSOR(CUR);
EXCEPTION 
    WHEN OTHERS THEN
        DBMS_OUTPUT.PUT_LINE(SQLERRM(SQLCODE()) || ': ' || DBMS_UTILITY.FORMAT_ERROR_BACKTRACE);

The problem with the first version is that if you go back and add a second statement to the if or else clauses without remembering to add the curly braces, your code will break in unexpected and amusing ways.

Maintainability-wise, it's always smarter to use the second form.

EDIT: Ned points this out in the comments, but it's worth linking to here, too, I think. This is not just some ivory-tower hypothetical bullshit: https://www.imperialviolet.org/2014/02/22/applebug.html

You can try macro also.

#define NONE    0x00
#define DBG     0x1F
#define INFO    0x0F
#define ERR     0x07
#define EMR     0x03
#define CRIT    0x01

#define DEBUG_LEVEL ERR

#define WHERESTR "[FILE : %s, FUNC : %s, LINE : %d]: "
#define WHEREARG __FILE__,__func__,__LINE__
#define DEBUG(...)  fprintf(stderr, __VA_ARGS__)
#define DEBUG_PRINT(X, _fmt, ...)  if((DEBUG_LEVEL & X) == X) \
                                      DEBUG(WHERESTR _fmt, WHEREARG,__VA_ARGS__)

int main()
{
    int x=10;
    DEBUG_PRINT(DBG, "i am x %d\n", x);
    return 0;
}

There are many ways you can take back of table.

1. BCP (BULK COPY PROGRAM)
2. Generate Table Script with data
3. Make a copy of table using SELECT INTO, example here
4. SAVE Table Data Directly in a Flat file
5. Export Data using SSIS to any destination

It's actually a sensible question. Here's the answer from Excel 2010 help:

"The Workbook object is a member of the Workbooks collection. The Workbooks collection contains all the Workbook objects currently open in Microsoft Excel."

So, since that workbook isn't open - at least I assume it isn't - it can't be set as a workbook object. If it was open you'd just set it like:

Set wbk = workbooks("Master Benchmark Data Sheet.xlsx")

This should do the job:

const createQueryParams = params => 
      Object.keys(params)
            .map(k => `${k}=${encodeURI(params[k])}`)
            .join('&');

Example:

const params = { name : 'John', postcode: 'W1 2DL'}
const queryParams = createQueryParams(params)

Result:

name=John&postcode=W1%202DL

Try to connect to repositroy with url: http://github.com/<user>/<project>.git (http except https)

In your case you should clone like this:

git clone http://github.com/<user>/<project>.git

Note that cp A B; rm A is exactly mv A B. It'll be faster too, as you don't have to actually copy the bytes (assuming the destination is on the same filesystem), just rename the file. So you want cp A B; mv A C

If you have OS(64bit) and SSMS(64bit) and already install the AccessDatabaseEngine(64bit) and you still received an error, try this following solutions:

1: direct opening the sql server import and export wizard.

if you able to connect using direct sql server import and export wizard, then importing from SSMS is the issue, it's like activating 32bit if you import data from SSMS.

Instead of installing AccessDatabaseEngine(64bit) , try to use the AccessDatabaseEngine(32bit) , upon installation, windows will stop you for continuing the installation if you already have another app installed , if so , then use the following steps. This is from the MICROSOFT. The Quiet Installation.

If Office 365 is already installed, side by side detection will prevent the installation from proceeding. Instead perform a /quiet install of these components from command line. To do so, download the desired AccessDatabaseEngine.exe or AccessDatabaeEngine_x64.exe to your PC, open an administrative command prompt, and provide the installation path and switch Ex: C:\Files\AccessDatabaseEngine.exe /quiet

if you want only to update model if exist (without create it):

Model.objects.filter(id = 223).update(field1 = 2)

mysql query:

UPDATE `model` SET `field1` = 2 WHERE `model`.`id` = 223

In Java8

//will prints each element line by line
stack.forEach(System.out::println);

or

//to print with commas
stack.forEach(
    (ele) -> {
        System.out.print(ele + ",");
    }
);

Nobody mention for Windows world SubWCRev, which, properly used, can substitute needed data into the needed places automagically, if script call SubWCRev in form SubWCRev WC_PATH TPL-FILE READY-FILE

Sample of my post-commit hook (part of)

SubWCRev.exe CustomLocations Builder.tpl  z:\Builder.bat
...
call z:\Builder.bat

where my Builder.tpl is

svn.exe export trunk z:\trunk$WCDATE=%Y%m%d$-r$WCREV$

as result, I have every time bat-file with variable part - name of dir - which corresponds to the metadata of Working Copy

with open('Stud.txt','r') as f:
    newlines = []
    for line in f.readlines():
        newlines.append(line.replace('A', 'Orange'))
with open('Stud.txt', 'w') as f:
    for line in newlines:
        f.write(line)

Try this it will work --

if($('#EventStartTimeMin').val() === " ") {

    alert("Please enter start time!");

}

If your Manifest.xml has the default android:theme="@style/AppTheme"

Go to res/values/styles.xml and change

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

to

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

And the ActionBar is disappeared!

map returns RDD of equal number of elements while flatMap may not.

An example use case for flatMap Filter out missing or incorrect data.

An example use case for map Use in wide variety of cases where is the number of elements of input and output are the same.

number.csv

1
2
3
-
4
-
5

map.py adds all numbers in add.csv.

from operator import *

def f(row):
  try:
    return float(row)
  except Exception:
    return 0

rdd = sc.textFile('a.csv').map(f)

print(rdd.count())      # 7
print(rdd.reduce(add))  # 15.0

flatMap.py uses flatMap to filtered out missing data before addition. Less numbers are added compared to the previous version.

from operator import *

def f(row):
  try:
    return [float(row)]
  except Exception:
    return []

rdd = sc.textFile('a.csv').flatMap(f)

print(rdd.count())      # 5
print(rdd.reduce(add))  # 15.0

Other possible way is:

echo "text" | tee -a filename >/dev/null

The -a will append at the end of the file.

If needing sudo, use:

echo "text" | sudo tee -a filename >/dev/null

No need for cut or magic, in bash you can cut a string like so:

  ORGSTRING="123456"
  CUTSTRING=${ORGSTRING:0:-3}
  echo "The original string: $ORGSTRING"
  echo "The new, shorter and faster string: $CUTSTRING"

See http://tldp.org/LDP/abs/html/string-manipulation.html

To get sequence id use

SELECT pg_get_serial_sequence('tableName', 'ColumnName');

This will gives you sequesce id as tableName_ColumnName_seq

To Get Last seed number use

select currval(pg_get_serial_sequence('tableName', 'ColumnName'));

or if you know sequence id already use it directly.

select currval(tableName_ColumnName_seq);

It will gives you last seed number

To Reset seed number use

ALTER SEQUENCE tableName_ColumnName_seq RESTART WITH 45

System.String is immutable. When we modify the value of a string variable then a new memory is allocated to the new value and the previous memory allocation released. System.StringBuilder was designed to have concept of a mutable string where a variety of operations can be performed without allocation separate memory location for the modified string.

For those discovering this now and the above answers didn't work, the issue I had was the screen wasn't big enough. I added this when initializing my ChromeDriver, and it fixed the problem:

options.add_argument("window-size=1200x600")

Try replaceAll() method of the String class.

BTW here is the method, return type and parameters.

public String replaceAll(String regex,
                         String replacement)

Example:

String str = "Hello +-^ my + - friends ^ ^^-- ^^^ +!";
str = str.replaceAll("[-+^]*", "");

It should remove all the {'^', '+', '-'} chars that you wanted to remove!

You can get your result by simply use substr():

Syntax substr(string,start,length)

Example

<?php
$myStr = "HelloWordl";
echo substr($myStr,0,5);
?>

Output :

 Hello

i=348842.
double i2=i/60000;
DecimalFormat dtime = new DecimalFormat("#.##"); 
i2= Double.valueOf(dtime.format(time));
v.setText(String.valueOf(i2));

It acts as curly bracket. We have to keep the number of white spaces consistent through out the program.

Example 1:

def main():
     print "we are in main function"
     print "print 2nd line"

main()

Result:

We are in main function
print 2nd line

Example 2:

def main():
    print "we are in main function"
print "print 2nd line"

main()

Result:

print 2nd line
We are in main function

Here, in the 1st program, both the statement comes under the main function since both have equal number of white spaces while in the 2nd program, the 1st line is printed later because the main function is called after the 2nd line Note - The 2nd line has no white space, so it is independent of the main function.

the core functions are getBytes(String charset) and new String(byte[] data). you can use these functions to do UTF-8 decoding.

UTF-8 decoding actually is a string to string conversion, the intermediate buffer is a byte array. since the target is an UTF-8 string, so the only parameter for new String() is the byte array, which calling is equal to new String(bytes, "UTF-8")

Then the key is the parameter for input encoded string to get internal byte array, which you should know beforehand. If you don't, guess the most possible one, "ISO-8859-1" is a good guess for English user.

The decoding sentence should be

String decoded = new String(encoded.getBytes("ISO-8859-1"));

Remove the quotes here:

is:

ORDER BY = 'post_datetime DESC' AND LIMIT = '3'

Should be:

ORDER BY post_datetime DESC LIMIT 3

Actually, even that didn't work for me. When I executed "select dbms_metadata.get_ddl('TABLESPACE','TABLESPACE_NAME') from dual;" I again got only the first three lines, but this time each line was padded out to 15,000 characters. I was able to work around this with:

select substr(dbms_metadata.get_ddl('TABLESPACE','LM_THIN_DATA'),80) from dual;
select substr(dbms_metadata.get_ddl('TABLESPACE','LM_THIN_DATA'),160) from dual;
select substr(dbms_metadata.get_ddl('TABLESPACE','LM_THIN_DATA'),240) from dual;

It sure seemed like there ought to be an easier way, but I couldn't seem to find it.

Some things to note:

You should always declare your enum inside a namespace as enums are not proper namespaces and you will be tempted to use them like one.

Always have a break at the end of each switch clause execution will continue downwards to the end otherwise.

Always include the default: case in your switch.

Use variables of enum type to hold enum values for clarity.

see here for a discussion of the correct use of enums in C++.

This is what you want to do.

namespace choices
{
    enum myChoice 
    { 
        EASY = 1 ,
        MEDIUM = 2, 
        HARD = 3  
    };
}

int main(int c, char** argv)
{
    choices::myChoice enumVar;
    cin >> enumVar;
    switch (enumVar)
    {
        case choices::EASY:
        {
            // do stuff
            break;
        }
        case choices::MEDIUM:
        {
            // do stuff
            break;
        }

        default:
        {
            // is likely to be an error
        }
    };

}

JavaScript actually does support encapsulation, through a method that involves hiding members in closures (Crockford). That said, it's sometimes cumbersome, and the underscore convention is a pretty good convention to use for things that are sort of private, but that you don't actually need to hide.

CSS style only for IE8:

.divLogRight{color:Blue; color:Red\9; *color:Blue;}

Only IE8 will be Red.

first Blue: for all browsers.

Red: IE6,7,8 Only

Second Blue: IE6,7 Only

So Red = for IE8 only.

For a very complete summary of browser hacks (including Internet Explorer (IE), Safari, Chrome, iPhone, and Opera) visit this link: http://paulirish.com/2009/browser-specific-css-hacks/

You can very easily iterate over dictionaries, too:

for team, scores in NL_East.iteritems():
    runs_scored = float(scores[0])
    runs_allowed = float(scores[1])
    win_percentage = round((runs_scored**2)/((runs_scored**2)+(runs_allowed**2))*1000)
    print '%s: %.1f%%' % (team, win_percentage)

You can use The Oracle Enterprise Manager to monitor the active sessions, with the query that is being executed, its execution plan, locks, some statistics and even a progress bar for the longer tasks.

See: http://download.oracle.com/docs/cd/B10501_01/em.920/a96674/db_admin.htm#1013955

Go to Instance -> sessions and watch the SQL Tab of each session.

There are other ways. Enterprise manager just puts with pretty colors what is already available in specials views like those documented here: http://www.oracle.com/pls/db92/db92.catalog_views?remark=homepage

And, of course you can also use Explain PLAN FOR, TRACE tool and tons of other ways of instrumentalization. There are some reports in the enterprise manager for the top most expensive SQL Queries. You can also search recent queries kept on the cache.

You can also have a look at the method findText(const QString & text) from QComboBox; it returns the index of the element which contains the given text, (-1 if not found). The advantage of using this method is that you don't need to set the second parameter when you add an item.

Here is a little example :

/* Create the comboBox */
QComboBox   *_comboBox = new QComboBox;

/* Create the ComboBox elements list (here we use QString) */
QList<QString> stringsList;
stringsList.append("Text1");
stringsList.append("Text3");
stringsList.append("Text4");
stringsList.append("Text2");
stringsList.append("Text5");

/* Populate the comboBox */
_comboBox->addItems(stringsList);

/* Create the label */
QLabel *label = new QLabel;

/* Search for "Text2" text */
int index = _comboBox->findText("Text2");
if( index == -1 )
    label->setText("Text2 not found !");
else
    label->setText(QString("Text2's index is ")
                   .append(QString::number(_comboBox->findText("Text2"))));

/* setup layout */
QVBoxLayout *layout = new QVBoxLayout(this);
layout->addWidget(_comboBox);
layout->addWidget(label);

You could use array.filter().

e.g.

        someArray = [{name:"Kristian", lines:"2,5,10"},
                     {name:"John", lines:"1,19,26,96"}];

        someArray = someArray.filter(function(returnableObjects){
               return returnableObjects.name !== 'Kristian';
        });

        //someArray will now be = [{name:"John", lines:"1,19,26,96"}];

Arrow functions:

someArray = someArray.filter(x => x.name !== 'Kristian')

This also works:

 getResources().getDisplayMetrics().density;

This will give you:

0.75 - ldpi

1.0 - mdpi

1.5 - hdpi

2.0 - xhdpi

3.0 - xxhdpi

4.0 - xxxhdpi

ref: density

Like Ianshark points out, a common reason for this error in Windows 7 is the Web Deployment Agent service.

The Web Deploy Tool enables administrators to use IIS Manager to deploy ASP.NET and PHP applications to an IIS server.

You can disable it from XAMPP Control Panel by clicking the "Services" button. If you have changed the port in the Apache config file, change it back to 80. Then uninstall Microsoft Web Deploy, if you prefer a more permanent solution.

Try to use the fleqn document class option.

\documentclass[fleqn]{article}

(See also http://en.wikibooks.org/wiki/LaTeX/Basics for a list of other options.)

strtotime(), as in date("F j, Y", strtotime("yesterday"));

Distinct and the aggregation framework are not inter-operable.

Instead you just want:

db.zips.aggregate([ 
    {$group:{_id:{city:'$city', state:'$state'}, numberOfzipcodes:{$sum:1}}}, 
    {$sort:{numberOfzipcodes:-1}},
    {$group:{_id:'$_id.state', city:{$first:'$_id.city'}, 
              numberOfzipcode:{$first:'$numberOfzipcodes'}}}
]);

Here is how you do in Eloquent

$users = User::whereIn('id', array(1, 2, 3))->get();

And if you are using Query builder then :

$users = DB::table('users')->whereIn('id', array(1, 2, 3))->get();

Full Outer join don't exist in mysql , you might need to use a combination of left and right join.

You can do one of the following:

<?php
    $data = 'My data';

    function menugen() {
        global $data;
        echo "[" . $data . "]";
    }

    menugen();

Or

<?php
    $data = 'My data';

    function menugen() {
        echo "[" . $GLOBALS['data'] . "]";
    }

    menugen();

That being said, overuse of globals can lead to some poor code. It is usually better to pass in what you need. For example, instead of referencing a global database object you should pass in a handle to the database and act upon that. This is called dependency injection. It makes your life a lot easier when you implement automated testing (which you should).

One trick I found was putting your setOnItemSelectedListeners in onWindowFocusChanged instead of onCreate. I haven't found any bad side-effects to doing it this way, yet. Basically, set up the listeners after the window gets drawn. I'm not sure how often onWindowFocusChanged runs, but it's easy enough to create yourself a lock variable if you are finding it running too often.

I think Android might be using a message-based processing system, and if you put it all in onCreate, you may run into situations where the spinner gets populated after it gets drawn. So, your listener will fire off after you set the item location. This is an educated guess, of course, but feel free to correct me on this.

You can use VBA - something like

Range("A1:A6").Interior.Color = RGB(127,187,199)

Just pass in the cell value.

You could try:

$(this).closest(".column").prev().find(".inputQty").val();

You have to import background component first to use backgroundimage on your code

Destructors provide an implicit way of freeing unmanaged resources encapsulated in your class, they get called when the GC gets around to it and they implicitly call the Finalize method of the base class. If you're using a lot of unmanaged resources it is better to provide an explicit way of freeing those resources via the IDisposable interface. See the C# programming guide: http://msdn.microsoft.com/en-us/library/66x5fx1b.aspx

preventDefault is what you're looking for. To just block the button from submitting

<Button onClick={this.onClickButton} ...

code

onClickButton (event) {
  event.preventDefault();
}

If you have a form which you want to handle in a custom way you can capture a higher level event onSubmit which will also stop that button from submitting.

<form onSubmit={this.onSubmit}>

and above in code

onSubmit (event) {
  event.preventDefault();

  // custom form handling here
}

In C, int, char, long, etc. are all integers.

They typically have different memory sizes and thus different ranges as in INT_MIN to INT_MAX. char and arrays of char are often used to store characters and strings. Integers are stored in many types: int being the most popular for a balance of speed, size and range.

ASCII is by far the most popular character encoding, but others exist. The ASCII code for an 'A' is 65, 'a' is 97, '\n' is 10, etc. ASCII data is most often stored in a char variable. If the C environment is using ASCII encoding, the following all store the same value into the integer variable.

int i1 = 'a';
int i2 = 97;
char c1 = 'a';
char c2 = 97;

To convert an int to a char, simple assign:

int i3 = 'b';
int i4 = i3;
char c3;
char c4;
c3 = i3;
// To avoid a potential compiler warning, use a cast `char`.
c4 = (char) i4; 

This warning comes up because int typically has a greater range than char and so some loss-of-information may occur. By using the cast (char), the potential loss of info is explicitly directed.

To print the value of an integer:

printf("<%c>\n", c3); // prints <b>

// Printing a `char` as an integer is less common but do-able
printf("<%d>\n", c3); // prints <98>

// Printing an `int` as a character is less common but do-able.
// The value is converted to an `unsigned char` and then printed.
printf("<%c>\n", i3); // prints <b>

printf("<%d>\n", i3); // prints <98>

There are additional issues about printing such as using %hhu or casting when printing an unsigned char, but leave that for later. There is a lot to printf().

What you want is to load the data again but not reload the div.

You need to make an Ajax query to get data from the server and fill the DIV.

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

you can use instead of click :

$('#whatever').on('touchstart click', function(){ /* do something... */ });
