It looks like jsbeautifier open sourced their tools and packaged them as Python and JS libs, and as CLI tools. It doesn't look like they call out to a web service, but I didn't check too closely. See the github repo with install instructions.

From their docs for Python CLI and library usage:

To beautify using python:

$ pip install jsbeautifier
$ js-beautify file.js

Beautified output goes to stdout.

To use jsbeautifier as a library is simple:

import jsbeautifier
res = jsbeautifier.beautify('your javascript string')
res = jsbeautifier.beautify_file('some_file.js')

...or, to specify some options:

opts = jsbeautifier.default_options()
opts.indent_size = 2
res = jsbeautifier.beautify('some javascript', opts)

If you want to pass a string instead of a filename, and you are using bash, then you can use process substitution like so:

$ js-beautify <(echo '{"some": "json"}')

As far as I know, using blocks instead of in-language control structures is more idiomatic.

given that you're a newbie, I'd say don't try to do this yet. it's definitely possible, but will needlessly complicate your Makefile. stick to the simple ways until you're more comfortable with make.

that said, one way to build in a directory different from the source directory is VPATH; i prefer pattern rules

selection opertion is used to select a subset of tuple from the relation that satisfied selection condition It filter out those tuple that satisfied the condition .Selection opertion can be visualized as horizontal partition into two set of tuple - those tuple satisfied the condition are selected and those tuple do not select the condition are discarded sigma (R) projection opertion is used to select a attribute from the relation that satisfied selection condition . It filter out only those tuple that satisfied the condition . The projection opertion can be visualized as a vertically partition into two part -are those satisfied the condition are selected other discarded ?(R) attribute list is a num of attribute

you must be using update in your hbm2ddl property. make the changes and update it to Create so that it can create the table.

<property name="hbm2ddl.auto">create</property>

It worked for me.

1. The currently preferred (Exchange 2013 and 2016) API is EWS. It is purely HTTP based and can be accessed from any language, but there are .Net and Java specific libraries.

   You can use EWSEditor to play with the API.

2. Extended MAPI. This is the native API used by Outlook. It ends up using the MSEMS Exchange MAPI provider, which can talk to Exchange using RPC (Exchange 2013 no longer supports it) or RPC-over-HTTP (Exchange 2007 or newer) or MAPI-over-HTTP (Exchange 2013 and newer).

   The API itself can only be accessed from unmanaged C++ or Delphi. You can also use Redemption (any language) - its RDO family of objects is an Extended MAPI wrapper. To use Extended MAPI, you need to install either Outlook or the standalone (Exchange) version of MAPI (on extended support, and it does not support Unicode PST and MSG files and cannot access Exchange 2016). Extended MAPI can be used in a service.

   You can play with the API using OutlookSpy or MFCMAPI.

3. Outlook Object Model - not Exchange specific, but it allows access to all data available in Outlook on the machine where the code runs. Cannot be used in a service.

4. Exchange Active Sync. Microsoft no longer invests any significant resources into this protocol.

5. Outlook used to install CDO 1.21 library (it wraps Extended MAPI), but it had been deprecated by Microsoft and no longer receives any updates.

6. There used to be a third-party .Net MAPI wrapper called MAPI33, but it is no longer being developed or supported.

7. WebDAV - deprecated.

8. Collaborative Data Objects for Exchange (CDOEX) - deprecated.

9. Exchange OLE DB Provider (EXOLEDB) - deprecated.

To work with the base Date class you can look at MDN for its methods (instead of W3Schools due to this reason). There you can find a good description about every method useful to access each single date/time component and informations relative to whether a method is deprecated or not.

Otherwise you can look at Moment.js that is a good library to use for date and time processing. You can use it to manipulate date and time (such as parsing, formatting, i18n, etc.).

You cannot have a class that extends two base classes. You could not have.

// this is NOT allowed (for all you google speeders)
Matron extends Nurse, HumanEntity

You could however have a hierarchy as follows...

Matron extends Nurse    
Consultant extends Doctor

Nurse extends HumanEntity
Doctor extends HumanEntity

HumanEntity extends DatabaseTable
DatabaseTable extends AbstractTable

and so on.

from __future__ import with_statement

try:
    with open( "a.txt" ) as f :
        print f.readlines()
except EnvironmentError: # parent of IOError, OSError *and* WindowsError where available
    print 'oops'

If you want different handling for errors from the open call vs the working code you could do:

try:
    f = open('foo.txt')
except IOError:
    print('error')
else:
    with f:
        print f.readlines()

I've created an eclipse plugin for this, because I had the same problem. Feel free to download it and contribute to it.

It's still in early development, but it does its job already for me.

Set the GroupName property of both radio buttons to the same value. You could also try using a RadioButtonGroup, which does this for you automatically.

Change your directive definition from app.module to app.directive. Apart from that everything looks fine. Btw, very rarely do you have to inject a service into a directive. If you are injecting a service ( which usually is a data source or model ) into your directive ( which is kind of part of a view ), you are creating a direct coupling between your view and model. You need to separate them out by wiring them together using a controller.

It does work fine. I am not sure what you are doing which is wrong. Here is a plunk of it working.

http://plnkr.co/edit/M8omDEjvPvBtrBHM84Am

--save-dev saves semver spec into "devDependencies" array in your package descriptor file, --save saves it into "dependencies" instead.

A dict is a hash table, so it is really fast to find the keys. So between dict and list, dict would be faster. But if you don't have a value to associate, it is even better to use a set. It is a hash table, without the "table" part.

EDIT: for your new question, YES, a set would be better. Just create 2 sets, one for sequences ended in 1 and other for the sequences ended in 89. I have sucessfully solved this problem using sets.

Make sure (django 1.5 and beyond) that you put the url name in quotes, and if your url takes parameters they should be outside of the quotes (I spent hours figuring out this mistake!).

{% url 'namespace:view_name' arg1=value1 arg2=value2 as the_url %}
<a href="{{ the_url }}"> link_name </a>

Since AngularJS does not have directive DOM manipulations as jQuery does, a proper way to modify attributes of one element will be using directive. Through link function of a directive, you have access to both element and its attributes.

Wrapping you whole input inside one directive, you can still introduce ng-model's methods through controller property.

This method will help to decouple the logic of ngmodel with placeholder from controller. If there is no logic between them, you can definitely go as Wagner Francisco said.

You will have to do this via AJAX. I HEAVILY reccommend you use jQuery to make this easier for you....

$("#idOfElement").on('click', function(){

    $.ajax({
       url: 'pathToPhpFile.php',
       dataType: 'json',
       success: function(data){
            //data returned from php
       }
    });
)};

In recent versions of Git you can add multiple pushurls for a given remote. Use the following to add two pushurls to your origin:

git remote set-url --add --push origin git://original/repo.git
git remote set-url --add --push origin git://another/repo.git

So when you push to origin, it will push to both repositories.

UPDATE 1: Git 1.8.0.1 and 1.8.1 (and possibly other versions) seem to have a bug that causes --add to replace the original URL the first time you use it, so you need to re-add the original URL using the same command. Doing git remote -v should reveal the current URLs for each remote.

UPDATE 2: Junio C. Hamano, the Git maintainer, explained it's how it was designed. Doing git remote set-url --add --push <remote_name> <url> adds a pushurl for a given remote, which overrides the default URL for pushes. However, you may add multiple pushurls for a given remote, which then allows you to push to multiple remotes using a single git push. You can verify this behavior below:

$ git clone git://original/repo.git
$ git remote -v
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.'
remote.origin.url=git://original/repo.git
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*

Now, if you want to push to two or more repositories using a single command, you may create a new remote named all (as suggested by @Adam Nelson in comments), or keep using the origin, though the latter name is less descriptive for this purpose. If you still want to use origin, skip the following step, and use origin instead of all in all other steps.

So let's add a new remote called all that we'll reference later when pushing to multiple repositories:

$ git remote add all git://original/repo.git
$ git remote -v
all git://original/repo.git (fetch)               <-- ADDED
all git://original/repo.git (push)                <-- ADDED
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.all'
remote.all.url=git://original/repo.git            <-- ADDED
remote.all.fetch=+refs/heads/*:refs/remotes/all/* <-- ADDED

Then let's add a pushurl to the all remote, pointing to another repository:

$ git remote set-url --add --push all git://another/repo.git
$ git remote -v
all git://original/repo.git (fetch)
all git://another/repo.git (push)                 <-- CHANGED
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.all'
remote.all.url=git://original/repo.git
remote.all.fetch=+refs/heads/*:refs/remotes/all/*
remote.all.pushurl=git://another/repo.git         <-- ADDED

Here git remote -v shows the new pushurl for push, so if you do git push all master, it will push the master branch to git://another/repo.git only. This shows how pushurl overrides the default url (remote.all.url).

Now let's add another pushurl pointing to the original repository:

$ git remote set-url --add --push all git://original/repo.git
$ git remote -v
all git://original/repo.git (fetch)
all git://another/repo.git (push)
all git://original/repo.git (push)                <-- ADDED
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.all'
remote.all.url=git://original/repo.git
remote.all.fetch=+refs/heads/*:refs/remotes/all/*
remote.all.pushurl=git://another/repo.git
remote.all.pushurl=git://original/repo.git        <-- ADDED

You see both pushurls we added are kept. Now a single git push all master will push the master branch to both git://another/repo.git and git://original/repo.git.

There is the easiest method, using File::Slurp module:

use File::Slurp;
my @lines = read_file("filename", chomp => 1); # will chomp() each line

If you need some validation for each line you can use grep in front of read_file.

For example, filter lines which contain only integers:

my @lines = grep { /^\d+$/ } read_file("filename", chomp => 1);

Calendar start = Calendar.getInstance();
Calendar end = Calendar.getInstance();
start.set(2010, 7, 23);
end.set(2010, 8, 26);
Date startDate = start.getTime();
Date endDate = end.getTime();
long startTime = startDate.getTime();
long endTime = endDate.getTime();
long diffTime = endTime - startTime;
long diffDays = diffTime / (1000 * 60 * 60 * 24);
DateFormat dateFormat = DateFormat.getDateInstance();
System.out.println("The difference between "+
  dateFormat.format(startDate)+" and "+
  dateFormat.format(endDate)+" is "+
  diffDays+" days.");

This will not work when crossing daylight savings time (or leap seconds) as orange80 pointed out and might as well not give the expected results when using different times of day. Using JodaTime might be easier for correct results, as the only correct way with plain Java before 8 I know is to use Calendar's add and before/after methods to check and adjust the calculation:

start.add(Calendar.DAY_OF_MONTH, (int)diffDays);
while (start.before(end)) {
    start.add(Calendar.DAY_OF_MONTH, 1);
    diffDays++;
}
while (start.after(end)) {
    start.add(Calendar.DAY_OF_MONTH, -1);
    diffDays--;
}

No, Bootstrap doesn't have a class for that, but this kind of class is considered a "utility" class, similar to the ".pull-right" class that @anton mentioned.

If you look at utilities.less you will see very few utility classes in Bootstrap, the reason being that this kind of class is generally frowned upon, and is recommended to be used for either: a) prototyping and development - so you can quickly build out your pages, then remove the pull-right and pull-left classes in favor of applying floats to more semantic classes or to the elements themselves, or b) when it's clearly more practical than a more semantic solution.

In your case, by your question it looks like you wish to have certain text align on the right in your table, but not all of it. Semantically, it would be better to do something like (I'm just going to make up a few classes here, except for the default bootstrap class, .table):

  <table class="table price-table">
    <thead>
      <th class="price-label">Total</th>
    </thead>
    <tbody>
      <tr>
        <td class="price-value">$1,000,000.00</td>
      </tr>
    </tbody>
  </table>

And just apply the text-align: left or text-align: right declarations to the price-value and price-label classes (or whatever classes work for you).

The problem with applying align-right as a class, is that if you want to refactor your tables you will have to redo the markup and the styles. If you use semantic classes you might be able to get away with refactoring only the CSS content. Plus, if are taking the time to apply a class to an element, it's best practice to try to assign semantic value to that class so that the markup is easier to navigate for other programmers (or you three months later).

One way to think of it is this: when you pose the question "What is this td for?", you will not get clarification from the answer "align-right".

You can negate a time.Duration:

then := now.Add(- dur)

You can even compare a time.Duration against 0:

if dur > 0 {
    dur = - dur
}

then := now.Add(dur)

You can see a working example at http://play.golang.org/p/ml7svlL4eW

In your case you can use __FILE__ variable !
It should help.
It is one of predefined.

Yes, you can configure the Spring servlet context xml file to define your beans (i.e., classes), so that it can do the automatic injection for you. However, do note, that you have to do other configurations to have Spring up and running and the best way to do that, is to follow a tutorial ground up.

Once you have your Spring configured probably, you can do the following in your Spring servlet context xml file for Example 1 above to work (please replace the package name of com.movies to what the true package name is and if this is a 3rd party class, then be sure that the appropriate jar file is on the classpath) :

<beans:bean id="movieFinder" class="com.movies.MovieFinder" />

or if the MovieFinder class has a constructor with a primitive value, then you could something like this,

<beans:bean id="movieFinder" class="com.movies.MovieFinder" >
    <beans:constructor-arg value="100" />
</beans:bean>

or if the MovieFinder class has a constructor expecting another class, then you could do something like this,

<beans:bean id="movieFinder" class="com.movies.MovieFinder" >
    <beans:constructor-arg ref="otherBeanRef" />
</beans:bean>

...where 'otherBeanRef' is another bean that has a reference to the expected class.

This answer will fail if value = 1.005.

As a better solution, the rounding problem can be avoided by using numbers represented in exponential notation:

Number(Math.round(1.005+'e2')+'e-2'); // 1.01

Cleaner code as suggested by @Kon, and the original author:

Number(Math.round(parseFloat(value + 'e' + decimalPlaces)) + 'e-' + decimalPlaces)

You may add toFixed() at the end to retain the decimal point e.g: 1.00 but note that it will return as string.

Number(Math.round(parseFloat(value + 'e' + decimalPlaces)) + 'e-' + decimalPlaces).toFixed(decimalPlaces)

You may write a recursive algorithm in Batch that gives you exact control of what you do in every nested subdirectory:

@echo off
call :treeProcess
goto :eof

:treeProcess
rem Do whatever you want here over the files of this subdir, for example:
copy *.* C:\dest\dir
for /D %%d in (*) do (
    cd %%d
    call :treeProcess
    cd ..
)
exit /b

Windows Batch File Looping Through Directories to Process Files?

After Ctrl+F'ing after Scanner, I think that the Scanner solution should be listed too. In the easiest to read fashion it goes like this:

public String fileToString(File file, Charset charset) {
  Scanner fileReader = new Scanner(file, charset);
  fileReader.useDelimiter("\\Z"); // \Z means EOF.
  String out = fileReader.next();
  fileReader.close();
  return out;
}

If you use Java 7 or newer (and you really should) consider using try-with-resources to make the code easier to read. No more dot-close stuff littering everything. But that's mostly a stylistic choice methinks.

I'm posting this mostly for completionism, since if you need to do this a lot, there should be things in java.nio.file.Files that should do the job better.

My suggestion would be to use Files#readAllBytes(Path) to grab all the bytes, and feed it to new String(byte[] Charset) to get a String out of it that you can trust. Charsets will be mean to you during your lifetime, so beware of this stuff now.

Others have given code and stuff, and I don't want to steal their glory. ;)

We can easily add multiple images using CSS3. we can read in detail here http://www.w3schools.com/css/css3_backgrounds.asp

I would suggest checking the drivers and updating them if required.

For the OP's command:

select compid,2, convert(datetime, '01/01/' + CONVERT(char(4),cal_yr) ,101) ,0,  Update_dt, th1, th2, th3_pc , Update_id, Update_dt,1
from  #tmp_CTF** 

I get this error:

Msg 102, Level 15, State 1, Line 2
Incorrect syntax near '*'.

when debugging something like this split the long line up so you'll get a better row number:

select compid
,2
, convert(datetime
, '01/01/' 
+ CONVERT(char(4)
,cal_yr) 
,101) 
,0
,  Update_dt
, th1
, th2
, th3_pc 
, Update_id
, Update_dt
,1
from  #tmp_CTF** 

this now results in:

Msg 102, Level 15, State 1, Line 16
Incorrect syntax near '*'.

which is probably just from the OP not putting the entire command in the question, or use [ ] braces to signify the table name:

from [#tmp_CTF**]

if that is the table name.

I wanted to put cursor at the end of a "div" element where contenteditable = true, and I got a solution with Xeoncross code:

<input type="button" value="Paste HTML" onclick="document.getElementById('test').focus(); pasteHtmlAtCaret('<b>INSERTED</b>'); ">

<div id="test" contenteditable="true">
    Here is some nice text
</div>

And this function do magic:

 function pasteHtmlAtCaret(html) {
    var sel, range;
    if (window.getSelection) {
        // IE9 and non-IE
        sel = window.getSelection();
        if (sel.getRangeAt && sel.rangeCount) {
            range = sel.getRangeAt(0);
            range.deleteContents();

            // Range.createContextualFragment() would be useful here but is
            // non-standard and not supported in all browsers (IE9, for one)
            var el = document.createElement("div");
            el.innerHTML = html;
            var frag = document.createDocumentFragment(), node, lastNode;
            while ( (node = el.firstChild) ) {
                lastNode = frag.appendChild(node);
            }
            range.insertNode(frag);

            // Preserve the selection
            if (lastNode) {
                range = range.cloneRange();
                range.setStartAfter(lastNode);
                range.collapse(true);
                sel.removeAllRanges();
                sel.addRange(range);
            }
        }
    } else if (document.selection && document.selection.type != "Control") {
        // IE < 9
        document.selection.createRange().pasteHTML(html);
    }
}

Works fine for most browsers, please check it, this code puts text and put focus at the end of the text in div element (not input element)

Thanks, Xeoncross

I use a generic class that inherit from ArrayList and implement a constructor with a parameter with variable number or arguments :

public class MyArrayList<T> extends ArrayList<T> {
    public MyArrayList(T...items){
        for (T item : items) {
            this.add(item);
        }
    }
}

Example:

MyArrayList<String>myArrayList=new MyArrayList<String>("s1","s2","s2");

ref is in and out.

You should use out in preference wherever it suffices for your requirements.

Tell the interviewer that it depends entirely on the implementation of the OS.

Take Windows x86 for example. There are only 2 segments [1], Code and Data. And they're both mapped to the whole 2GB (linear, user) address space. Base=0, Limit=2GB. They would've made one but x86 doesn't allow a segment to be both Read/Write and Execute. So they made two, and set CS to point to the code descriptor, and the rest (DS, ES, SS, etc) to point to the other [2]. But both point to the same stuff!

The person interviewing you had made a hidden assumption that he/she did not state, and that is a stupid trick to pull.

So regarding

Q. So tell me which segment thread share?

The segments are irrelevant to the question, at least on Windows. Threads share the whole address space. There is only 1 stack segment, SS, and it points to the exact same stuff that DS, ES, and CS do [2]. I.e. the whole bloody user space. 0-2GB. Of course, that doesn't mean threads only have 1 stack. Naturally each has its own stack, but x86 segments are not used for this purpose.

Maybe *nix does something different. Who knows. The premise the question was based on was broken.

1. At least for user space.
2. From ntsd notepad: cs=001b ss=0023 ds=0023 es=0023

git log origin/master..master

or, more generally:

git log <since>..<until>

You can use this with grep to check for a specific, known commit:

git log <since>..<until> | grep <commit-hash>

Or you can also use git-rev-list to search for a specific commit:

git rev-list origin/master | grep <commit-hash>

In my case, I got this while overloading

ostream & operator << (ostream &out, const MyClass &obj)

and forgot to return out. In other systems this just generates a warning, but on macos it also generated an error (although it seems to print correctly).

The error was resolved by adding the correct return value. In my case, adding the -mmacosx-version-min flag had no effect.

If you add the extension .SH to the environment variable PATHEXT, you will be able to run shell scripts from PowerShell by only using the script name with arguments:

PS> .\script.sh args

If you store your scripts in a directory that is included in your PATH environment variable, you can run it from anywhere, and omit the extension and path:

PS> script args

Note: sh.exe or another *nix shell must be associated with the .sh extension.

Create a stateful color for your button, just like you did for background, for example:

    <item android:state_focused="true" 
          android:state_pressed="false" 
          android:color="#ffffff" />

    <!-- Focused and pressed -->
    <item android:state_focused="true" 
          android:state_pressed="true" 
          android:color="#000000" />

    <!-- Unfocused and pressed -->
    <item android:state_focused="false" 
          android:state_pressed="true" 
          android:color="#000000" />

    <!-- Default color -->
    <item android:color="#ffffff" />

</selector>

Place the xml in a file at res/drawable folder i.e. res/drawable/button_text_color.xml. Then just set the drawable as text color:

android:textColor="@drawable/button_text_color"

Not answering the question directly, but it might help someone else.

I have a column called Volume, having both - (invalid/NaN) and numbers formatted with ,

df['Volume'] = df['Volume'].astype('str')
df['Volume'] = df['Volume'].str.replace(',', '')
df['Volume'] = pd.to_numeric(df['Volume'], errors='coerce')

Casting to string is required for it to apply to str.replace

pandas.Series.str.replace
pandas.to_numeric

enum Enum{ Banana, Orange, Apple } ;
static const char * EnumStrings[] = { "bananas & monkeys", "Round and orange", "APPLE" };

const char * getTextForEnum( int enumVal )
{
  return EnumStrings[enumVal];
}

You can remove the blue outline by using outline: none.

However, I would highly recommend styling your focus states too. This is to help users who are visually impaired.

After trying all of this solutions, I still had different problems. So what I found the simplest way was to create a python file: config.py, with a dictionary containing the file's absolute path and import it into the script. something like

import config as cfg 
import pandas as pd 
pd.read_csv(cfg.paths['myfilepath'])

where config.py has inside:

paths = {'myfilepath': 'home/docs/...'}

It is not automatic but it is a good solution when you have to work in different directory or different machines.

There is one more way without triggering an custom event

A jQuery Plug-in to monitor Html Element CSS Changes by Rick Strahl

Quoting from above

The watch plug-in works by hooking up to DOMAttrModified in FireFox, to onPropertyChanged in Internet Explorer, or by using a timer with setInterval to handle the detection of changes for other browsers. Unfortunately WebKit doesn’t support DOMAttrModified consistently at the moment so Safari and Chrome currently have to use the slower setInterval mechanism.

If you have opened a file in preview mode and want to open new file in another tab: For Mac: use cmd + p -> find the file and alt + enter.

Best option is to use the '?' argument for the method. This way DBMS_MVIEW will choose the best way to refresh, so it'll do the fastest refresh it can for you. , and won't fail if you try something like method=>'f' when you actually need a complete refresh. :-)

from the SQL*Plus prompt:

EXEC DBMS_MVIEW.REFRESH('my_schema.my_mview', method => '?');

This post got me to my answer even though the answer is missing from this post. I felt I should give back.

The challenge here is in the inconsistent behavior of BeautifulSoup.find when searching with and without text.

Note: If you have BeautifulSoup, you can test this locally via:

curl https://gist.githubusercontent.com/RichardBronosky/4060082/raw/test.py | python

Code: https://gist.github.com/4060082

# Taken from https://gist.github.com/4060082
from BeautifulSoup import BeautifulSoup
from urllib2 import urlopen
from pprint import pprint
import re

soup = BeautifulSoup(urlopen('https://gist.githubusercontent.com/RichardBronosky/4060082/raw/test.html').read())
# I'm going to assume that Peter knew that re.compile is meant to cache a computation result for a performance benefit. However, I'm going to do that explicitly here to be very clear.
pattern = re.compile('Fixed text')

# Peter's suggestion here returns a list of what appear to be strings
columns = soup.findAll('td', text=pattern, attrs={'class' : 'pos'})
# ...but it is actually a BeautifulSoup.NavigableString
print type(columns[0])
#>> <class 'BeautifulSoup.NavigableString'>

# you can reach the tag using one of the convenience attributes seen here
pprint(columns[0].__dict__)
#>> {'next': <br />,
#>>  'nextSibling': <br />,
#>>  'parent': <td class="pos">\n
#>>       "Fixed text:"\n
#>>       <br />\n
#>>       <strong>text I am looking for</strong>\n
#>>   </td>,
#>>  'previous': <td class="pos">\n
#>>       "Fixed text:"\n
#>>       <br />\n
#>>       <strong>text I am looking for</strong>\n
#>>   </td>,
#>>  'previousSibling': None}

# I feel that 'parent' is safer to use than 'previous' based on http://www.crummy.com/software/BeautifulSoup/bs4/doc/#method-names
# So, if you want to find the 'text' in the 'strong' element...
pprint([t.parent.find('strong').text for t in soup.findAll('td', text=pattern, attrs={'class' : 'pos'})])
#>> [u'text I am looking for']

# Here is what we have learned:
print soup.find('strong')
#>> <strong>some value</strong>
print soup.find('strong', text='some value')
#>> u'some value'
print soup.find('strong', text='some value').parent
#>> <strong>some value</strong>
print soup.find('strong', text='some value') == soup.find('strong')
#>> False
print soup.find('strong', text='some value') == soup.find('strong').text
#>> True
print soup.find('strong', text='some value').parent == soup.find('strong')
#>> True

Though it is most certainly too late to help the OP, I hope they will make this as the answer since it does satisfy all quandaries around finding by text.

data.reindex(index=data.index[::-1])

or simply:

data.iloc[::-1]

will reverse your data frame, if you want to have a for loop which goes from down to up you may do:

for idx in reversed(data.index):
    print(idx, data.loc[idx, 'Even'], data.loc[idx, 'Odd'])

or

for idx in reversed(data.index):
    print(idx, data.Even[idx], data.Odd[idx])

You are getting an error because reversed first calls data.__len__() which returns 6. Then it tries to call data[j - 1] for j in range(6, 0, -1), and the first call would be data[5]; but in pandas dataframe data[5] means column 5, and there is no column 5 so it will throw an exception. ( see docs )

The operators <- and = assign into the environment in which they are evaluated. The operator <- can be used anywhere, whereas the operator = is only allowed at the top level (e.g., in the complete expression typed at the command prompt) or as one of the subexpressions in a braced list of expressions.

If you use Eclipse as your IDE I would recommend the excellent eclipse plugin memory analyzer

Another option is to use JVisualVM, it can read (and create) heap dumps as well, and is shipped with every JDK. You can find it in the bin directory of your JDK.

Here is a generic working solution based on @Beta's

I'm using GNU Make 4.1 with SHELL=/bin/bash atop my Makefile, so YMMV!

This allows us to accept extra arguments (by doing nothing when we get a job that doesn't match, rather than throwing an error).

%:
    @:

And this is a macro which gets the args for us:

args = `arg="$(filter-out $@,$(MAKECMDGOALS))" && echo $${arg:-${1}}`

Here is a job which might call this one:

test:
    @echo $(call args,defaultstring)

The result would be:

$ make test
defaultstring
$ make test hi
hi

Note! You might be better off using a "Taskfile", which is a bash pattern that works similarly to make, only without the nuances of Maketools. See https://github.com/adriancooney/Taskfile

Raystorm had a good answer. I'm not a big fan of Rules either. I do something similar, except that I create the following utility class to help readability and usability, which is one of the big plus'es of annotations in the first place.

Add this utility class:

import org.junit.Assert;

public abstract class ExpectedRuntimeExceptionAsserter {

    private String expectedExceptionMessage;

    public ExpectedRuntimeExceptionAsserter(String expectedExceptionMessage) {
        this.expectedExceptionMessage = expectedExceptionMessage;
    }

    public final void run(){
        try{
            expectException();
            Assert.fail(String.format("Expected a RuntimeException '%s'", expectedExceptionMessage));
        } catch (RuntimeException e){
            Assert.assertEquals("RuntimeException caught, but unexpected message", expectedExceptionMessage, e.getMessage());
        }
    }

    protected abstract void expectException();

}

Then for my unit test, all I need is this code:

@Test
public void verifyAnonymousUserCantAccessPrivilegedResourceTest(){
    new ExpectedRuntimeExceptionAsserter("anonymous user can't access privileged resource"){
        @Override
        protected void expectException() {
            throw new RuntimeException("anonymous user can't access privileged resource");
        }
    }.run(); //passes test; expected exception is caught, and this @Test returns normally as "Passed"
}

Try to use this a very simple way and call it like your own func

public static String convertnumtocharmonths(int m){
         String charname=null;
         if(m==1){
             charname="Jan";
         }
         if(m==2){
             charname="Fev";
         }
         if(m==3){
             charname="Mar";
         }
         if(m==4){
             charname="Avr";
         }
         if(m==5){
             charname="Mai";
         }
         if(m==6){
             charname="Jun";
         }
         if(m==7){
             charname="Jul";
         }
         if(m==8){
             charname="Aou";
         }
         if(m==9){
             charname="Sep";
         }
         if(m==10){
             charname="Oct";
         }
         if(m==11){
             charname="Nov";
         }
         if(m==12){
             charname="Dec";
         }
         return charname;
     }

If you're going with jdk6 update 14, I'd suggest using using the G1 garbage collector which seems to help performance.

To do so, remove these settings:

-XX:+UseConcMarkSweepGC
-XX:+CMSIncrementalMode
-XX:+CMSIncrementalPacing

and replace them with these:

-XX:+UnlockExperimentalVMOptions
-XX:+UseG1GC

Downgrading the JRE from 7 to 6 fixed this issue for me.

Here's an alternate approach to the 'round up' part. Not the most brilliantly coded solution but it gets the job done, and this type of syntax is a bit easier to remember (plus would work for alignment values that aren't a power of 2). The uintptr_t cast was necessary to appease the compiler; pointer arithmetic isn't very fond of division or multiplication.

void *mem = malloc(1024 + 15);
void *ptr = (void*) ((uintptr_t) mem + 15) / 16 * 16;
memset_16aligned(ptr, 0, 1024);
free(mem);

This seems a far easier method than those suggested elsewhere in this thread.

split rows in pandas dataframe

An enum type is a special type of class.

Your enum will actually be compiled to something like

public final class MySingleton {
    public final static MySingleton INSTANCE = new MySingleton();
    private MySingleton(){} 
}

When your code first accesses INSTANCE, the class MySingleton will be loaded and initialized by the JVM. This process initializes the static field above once (lazily).

This is because Code signing no longer allows any file in an app bundle to have an extended attribute containing a resource fork or Finder info.

To see which files are causing this error, go to .app folder, normally is like: /Users/XXXX/Library/Developer/Xcode/DerivedData/MyProject-ckbzynxqjmstxigbdwwkcsozlego/Build/Products/Debug-maccatalyst/ (mine is Catalyst project) In Terminal,

cd <above path>
xattr -lr .

You will see some files has extended attribute:

./MyProject.app/Contents/Resources/shopping_cart.png: com.apple.lastuseddate#PS: 00000000 BE 31 D5 5E 00 00 00 00 D0 40 FE 39 00 00 00 00 |.1.^[email protected]....|

Then go to your project folder or referenced folder for those files, remove extended attribute:

cd /Users/XXXX/Work/MyProject
xattr -cr .

After clean all referenced folders, go to Xcode and rebuild.

If you got Destination path XXX already exists means the name of the project repository which you are trying to clone is already there in that current directory. So please cross-check and delete any existing one and try to clone it again

This worked for me:

Select
    dateadd(S, [unixtime], '1970-01-01')
From [Table]

In case any one wonders why 1970-01-01, This is called Epoch time.

Below is a quote from Wikipedia:

The number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970,[1][note 1] not counting leap seconds.

Use this, and you will find all informations at http://www.w3schools.com/html/html5_geolocation.asp

<script>
var x = document.getElementById("demo");
function getLocation() {
    if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(showPosition);
    } else {
        x.innerHTML = "Geolocation is not supported by this browser.";
    }
}
function showPosition(position) {
    x.innerHTML = "Latitude: " + position.coords.latitude + 
    "<br>Longitude: " + position.coords.longitude; 
}
</script>

If you don't want conditional compilation you can just write endian independent code. Here is an example (taken from Rob Pike):

Reading an integer stored in little-endian on disk, in an endian independent manner:

i = (data[0]<<0) | (data[1]<<8) | (data[2]<<16) | (data[3]<<24);

The same code, trying to take into account the machine endianness:

i = *((int*)data);
#ifdef BIG_ENDIAN
/* swap the bytes */
i = ((i&0xFF)<<24) | (((i>>8)&0xFF)<<16) | (((i>>16)&0xFF)<<8) | (((i>>24)&0xFF)<<0);
#endif

The usual way is to use zip():

for x, y in zip(a, b):
    # x is from a, y is from b

This will stop when the shorter of the two iterables a and b is exhausted. Also worth noting: itertools.izip() (Python 2 only) and itertools.izip_longest() (itertools.zip_longest() in Python 3).

As stated in other answers this can be achieved with:

• A copy of the blurred image as the background.
• A pseudo element that can be filtered then positioned behind the content.

You can also use backdrop-filter

There is a supported property called backdrop-filter, and it is currently supported in Chrome 76, Edge, Safari, and iOS Safari (see caniuse.com for statistics).

From Mozilla devdocs:

The backdrop-filter property provides for effects like blurring or color shifting the area behind an element, which can then be seen through that element by adjusting the element's transparency/opacity.

See caniuse.com for usage statistics.

You would use it like so. If you do not want content inside to be blurred use the utility class .u-non-blurred

.background-filter::after {
  -webkit-backdrop-filter: blur(5px); /* Use for Safari 9+, Edge 17+ (not a mistake) and iOS Safari 9.2+ */
  backdrop-filter: blur(5px); /* Supported in Chrome 76 */

  content: "";
  display: block;
  position: absolute;
  width: 100%; height: 100%;
  top: 0;
}

.background-filter {
  position: relative;
}

.background {
  background-image: url('https://upload.wikimedia.org/wikipedia/en/6/62/Kermit_the_Frog.jpg');
  width: 200px;
  height: 200px;
}

/* Use for content that should not be blurred */
.u-non-blurred {
  position: relative;
  z-index: 1;
}

<div class="background background-filter"></div>
<div class="background background-filter">
  <h1 class="u-non-blurred">Kermit D. Frog</h1>
</div>

Update (12/06/2019): Chromium will ship with backdrop-filter enabled by default in version 76 which is due out 30/07/2019.

Update (01/06/2019): The Mozzilla Firefox team has announced it will start working on implementing this soon.

Update (21/05/2019): Chromium just announced backdrop-filter is available in chrome canary without enabling "Enable Experimental Web Platform Features" flag. This means backdrop-filter is very close to being implemented on all chrome platforms.

adding HTTP headers using urllib2:

from the docs:

import urllib2
req = urllib2.Request('http://www.example.com/')
req.add_header('Referer', 'http://www.python.org/')
resp = urllib2.urlopen(req)
content = resp.read()

The simplest thing you can do is use reset.css. It normalizes the default stylesheet across browsers, and coincidentally allows button { vertical-align: middle; } to work just fine. Give it a shot - I use it in virtually all of my projects just to kill little bugs like this.

I have tried different kinds of maps and the Conversion Box worked. I have used your map and have pasted an example below with some inner maps. Hope it is helpful to you ....

import java.util.HashMap;
import java.util.Map;

import cjm.component.cb.map.ToMap;
import cjm.component.cb.xml.ToXML;

public class Testing
{
public static void main(String[] args)
{
    try
    {
        Map<String, Object> map = new HashMap<String, Object>(); // ORIGINAL MAP

        map.put("name", "chris");
        map.put("island", "faranga");

        Map<String, String> mapInner = new HashMap<String, String>(); // SAMPLE INNER MAP

        mapInner.put("a", "A");
        mapInner.put("b", "B");
        mapInner.put("c", "C");

        map.put("innerMap", mapInner);

        Map<String, Object> mapRoot = new HashMap<String, Object>(); // ROOT MAP

        mapRoot.put("ROOT", map);

        System.out.println("Map: " + mapRoot);

        System.out.println();

        ToXML toXML = new ToXML();

        String convertedXML = String.valueOf(toXML.convertToXML(mapRoot, true)); // CONVERTING ROOT MAP TO XML

        System.out.println("Converted XML: " + convertedXML);

        System.out.println();

        ToMap toMap = new ToMap();

        Map<String, Object> convertedMap = toMap.convertToMap(convertedXML); // CONVERTING CONVERTED XML BACK TO MAP

        System.out.println("Converted Map: " + convertedMap);
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
}
}

Output:

What I did (Windows 10) for a new installation:

1. Start cmd in admin mode (run as administrator by hitting windows key, typing cmd, right clicking on it and selecting "Run as Administrator"

2. Change into "MySQL Server X.Y" directory (for me the full path is C:\Program Files\MySQL\MySQL Server 5.7")

3. using notepad create a my.ini with a mysqld section that points at your data directory

   [mysqld]
   datadir="X:\Your Directory Path and Name"
   

4. created the directory identified in my.ini above.

5. change into bin Directory under server directory and execute: mysqld --initialize

6. Once complete, started the service and it came up fine.

@majinboo's answer is revised for performance and memory management. Any more than one font need related Activity can use this Font class by giving the constructor itself as a parameter.

@Override
public void onCreate(Bundle savedInstanceState)
{
    Font font = new Font(this);
}

Revised Fonts class is as below:

public class Fonts

    private HashMap<AssetTypefaces, Typeface> hashMapFonts;

    private enum AssetTypefaces
    {
        RobotoLight,
        RobotoThin,

            {
                ((TextView) v).setTypeface(getTypeface(v.getTag().toString()));
            }
        }
        catch (Exception e)
        {
            e.printStackTrace();
            // ignore
        }
    }
}

First, let's clear up some terminology: "asynchronous" (async) means that it may yield control back to the calling thread before it starts. In an async method, those "yield" points are await expressions.

This is very different than the term "asynchronous", as (mis)used by the MSDN documentation for years to mean "executes on a background thread".

To futher confuse the issue, async is very different than "awaitable"; there are some async methods whose return types are not awaitable, and many methods returning awaitable types that are not async.

Enough about what they aren't; here's what they are:

• The async keyword allows an asynchronous method (that is, it allows await expressions). async methods may return Task, Task<T>, or (if you must) void.
• Any type that follows a certain pattern can be awaitable. The most common awaitable types are Task and Task<T>.

So, if we reformulate your question to "how can I run an operation on a background thread in a way that it's awaitable", the answer is to use Task.Run:

private Task<int> DoWorkAsync() // No async because the method does not need await
{
  return Task.Run(() =>
  {
    return 1 + 2;
  });
}

(But this pattern is a poor approach; see below).

But if your question is "how do I create an async method that can yield back to its caller instead of blocking", the answer is to declare the method async and use await for its "yielding" points:

private async Task<int> GetWebPageHtmlSizeAsync()
{
  var client = new HttpClient();
  var html = await client.GetAsync("http://www.example.com/");
  return html.Length;
}

So, the basic pattern of things is to have async code depend on "awaitables" in its await expressions. These "awaitables" can be other async methods or just regular methods returning awaitables. Regular methods returning Task/Task<T> can use Task.Run to execute code on a background thread, or (more commonly) they can use TaskCompletionSource<T> or one of its shortcuts (TaskFactory.FromAsync, Task.FromResult, etc). I don't recommend wrapping an entire method in Task.Run; synchronous methods should have synchronous signatures, and it should be left up to the consumer whether it should be wrapped in a Task.Run:

private int DoWork()
{
  return 1 + 2;
}

private void MoreSynchronousProcessing()
{
  // Execute it directly (synchronously), since we are also a synchronous method.
  var result = DoWork();
  ...
}

private async Task DoVariousThingsFromTheUIThreadAsync()
{
  // I have a bunch of async work to do, and I am executed on the UI thread.
  var result = await Task.Run(() => DoWork());
  ...
}

I have an async/await intro on my blog; at the end are some good followup resources. The MSDN docs for async are unusually good, too.

This is simple if you only use Selenium WebDriver, and forget the usage of Selenium-RC. I'd go like this.

WebDriver driver = new FirefoxDriver();
WebElement email = driver.findElement(By.id("email"));
email.sendKeys("[email protected]");

The reason for NullPointerException however is that your variable driver has never been started, you start FirefoxDriver in a variable wb thas is never being used.

What about to use replaceAll java.lang.String method:

    String str = "qwerty-1qwerty-2 455 f0gfg 4";      
    str = str.replaceAll("[^-?0-9]+", " "); 
    System.out.println(Arrays.asList(str.trim().split(" ")));

Output:

[-1, -2, 455, 0, 4]

Description

[^-?0-9]+

• [ and ] delimites a set of characters to be single matched, i.e., only one time in any order
• ^ Special identifier used in the beginning of the set, used to indicate to match all characters not present in the delimited set, instead of all characters present in the set.
• + Between one and unlimited times, as many times as possible, giving back as needed
• -? One of the characters “-” and “?”
• 0-9 A character in the range between “0” and “9”

You're not actually going out after the values. You would need to gather them like this:

var title   = document.getElementById("title").value;
var name    = document.getElementById("name").value;
var tickets = document.getElementById("tickets").value;

You could put all of these in one array:

var myArray = [ title, name, tickets ];

Or many arrays:

var titleArr   = [ title ];
var nameArr    = [ name ];
var ticketsArr = [ tickets ];

Or, if the arrays already exist, you can use their .push() method to push new values onto it:

var titleArr = [];

function addTitle ( title ) {
  titleArr.push( title );
  console.log( "Titles: " + titleArr.join(", ") );
}

Your save button doesn't work because you refer to this.form, however you don't have a form on the page. In order for this to work you would need to have <form> tags wrapping your fields:

I've made several corrections, and placed the changes on jsbin: http://jsbin.com/ufanep/2/edit

The new form follows:

<form>
  <h1>Please enter data</h1>
  <input id="title" type="text" />
  <input id="name" type="text" />
  <input id="tickets" type="text" />
  <input type="button" value="Save" onclick="insert()" />
  <input type="button" value="Show data" onclick="show()" />
</form>
<div id="display"></div>

There is still some room for improvement, such as removing the onclick attributes (those bindings should be done via JavaScript, but that's beyond the scope of this question).

I've also made some changes to your JavaScript. I start by creating three empty arrays:

var titles  = [];
var names   = [];
var tickets = [];

Now that we have these, we'll need references to our input fields.

var titleInput  = document.getElementById("title");
var nameInput   = document.getElementById("name");
var ticketInput = document.getElementById("tickets");

I'm also getting a reference to our message display box.

var messageBox  = document.getElementById("display");

The insert() function uses the references to each input field to get their value. It then uses the push() method on the respective arrays to put the current value into the array.

Once it's done, it cals the clearAndShow() function which is responsible for clearing these fields (making them ready for the next round of input), and showing the combined results of the three arrays.

function insert ( ) {
 titles.push( titleInput.value );
 names.push( nameInput.value );
 tickets.push( ticketInput.value );

 clearAndShow();
}

This function, as previously stated, starts by setting the .value property of each input to an empty string. It then clears out the .innerHTML of our message box. Lastly, it calls the join() method on all of our arrays to convert their values into a comma-separated list of values. This resulting string is then passed into the message box.

function clearAndShow () {
  titleInput.value = "";
  nameInput.value = "";
  ticketInput.value = "";

  messageBox.innerHTML = "";

  messageBox.innerHTML += "Titles: " + titles.join(", ") + "<br/>";
  messageBox.innerHTML += "Names: " + names.join(", ") + "<br/>";
  messageBox.innerHTML += "Tickets: " + tickets.join(", ");
}

The final result can be used online at http://jsbin.com/ufanep/2/edit

It could be not supported file encoding. Change it to UTF-8 for example.

I've done this using Sublime

You should map your virtual network drive in Windows.

1. Open command prompt in Windows (VirtualBox)
2. Execute: net use x: \\vboxsvr\<your_shared_folder_name>
3. You should see new drive X: in My Computer

In your case execute net use x: \\vboxsvr\win7

Go to the Sql tab run one of the below query:

delete from tableName;

Delete: will delete all rows from your table. Next insert will take next auto increment id.

or

truncate tableName;

Truncate: will also delete the rows from your table but it will start from new row with 1.

A detailed blog with example: http://sforsuresh.in/phpmyadmin-deleting-rows-mysql-table/

Basically you have two options

scale_x_continuous(limits = c(-5000, 5000))

or

coord_cartesian(xlim = c(-5000, 5000)) 

Where the first removes all data points outside the given range and the second only adjusts the visible area. In most cases you would not see the difference, but if you fit anything to the data it would probably change the fitted values.

You can also use the shorthand function xlim (or ylim), which like the first option removes data points outside of the given range:

+ xlim(-5000, 5000)

For more information check the description of coord_cartesian.

The RStudio cheatsheet for ggplot2 makes this quite clear visually. Here is a small section of that cheatsheet:

@RequestMapping(value = "/testonly", method = { RequestMethod.GET, RequestMethod.POST })
public ModelAndView listBooksPOST(@ModelAttribute("booksFilter") BooksFilter filter,
        @RequestParam(required = false) String parameter1,
        @RequestParam(required = false) String parameter2, 
        BindingResult result, HttpServletRequest request) 
        throws ParseException {

    LONG CODE and SAME LONG CODE with a minor difference
}

if @RequestParam(required = true) then you must pass parameter1,parameter2

Use BindingResult and request them based on your conditions.

The Other way

@RequestMapping(value = "/books", method = RequestMethod.GET)
public ModelAndView listBooks(@ModelAttribute("booksFilter") BooksFilter filter,  
    two @RequestParam parameters, HttpServletRequest request) throws ParseException {

    myMethod();

}


@RequestMapping(value = "/books", method = RequestMethod.POST)
public ModelAndView listBooksPOST(@ModelAttribute("booksFilter") BooksFilter filter, 
        BindingResult result) throws ParseException {

    myMethod();

    do here your minor difference
}

private returntype myMethod(){
    LONG CODE
}

Nothing. It was added to the C99 standard.

To simplify Kirubaharan's answer a bit:

df['Datetime'] = pd.to_datetime(df['date'] + ' ' + df['time'])
df = df.set_index('Datetime')

And to get rid of unwanted columns (as OP did but did not specify per se in the question):

df = df.drop(['date','time'], axis=1)

How can I check if I have listed all the dependencies correctly?

The pbuilder is an excellent tool for checking both build dependencies and dependencies by setting up a clean base system within a chroot environment. By compiling the package within pbuilder, you can easily check the build dependencies, and by testing it within a pbuilder environment, you can check the dependencies.

No, don't spoil it with a break. This is the last remaining stronghold for the use of goto.

Mark, this is already answered in your previous topic. But OK, here it is again:

Suppose ${list} points to a List<Object>, then the following

<c:forEach items="${list}" var="item">
    ${item}<br>
</c:forEach>

does basically the same as as following in "normal Java":

for (Object item : list) {
    System.out.println(item);
}

If you have a List<Map<K, V>> instead, then the following

<c:forEach items="${list}" var="map">
    <c:forEach items="${map}" var="entry">
        ${entry.key}<br>
        ${entry.value}<br>
    </c:forEach>
</c:forEach>

does basically the same as as following in "normal Java":

for (Map<K, V> map : list) {
    for (Entry<K, V> entry : map.entrySet()) {
        System.out.println(entry.getKey());
        System.out.println(entry.getValue());
    }
}

The key and value are here not special methods or so. They are actually getter methods of Map.Entry object (click at the blue Map.Entry link to see the API doc). In EL (Expression Language) you can use the . dot operator to access getter methods using "property name" (the getter method name without the get prefix), all just according the Javabean specification.

That said, you really need to cleanup the "answers" in your previous topic as they adds noise to the question. Also read the comments I posted in your "answers".

The R in REST stands for resource

(Which isn't true, because it stands for Representational, but it's a good trick to remember the importance of Resources in REST).

About PUT /groups/api/v1/groups/{group id}/status/activate: you are not updating an "activate". An "activate" is not a thing, it's a verb. Verbs are never good resources. A rule of thumb: if the action, a verb, is in the URL, it probably is not RESTful.

What are you doing instead? Either you are "adding", "removing" or "updating" an activation on a Group, or if you prefer: manipulating a "status"-resource on a Group. Personally, I'd use "activations" because they are less ambiguous than the concept "status": creating a status is ambiguous, creating an activation is not.

• POST /groups/{group id}/activation Creates (or requests the creation of) an activation.
• PATCH /groups/{group id}/activation Updates some details of an existing activation. Since a group has only one activation, we know what activation-resource we are referring to.
• PUT /groups/{group id}/activation Inserts-or-replaces the old activation. Since a group has only one activation, we know what activation-resource we are referring to.
• DELETE /groups/{group id}/activation Will cancel, or remove the activation.

This pattern is useful when the "activation" of a Group has side-effects, such as payments being made, mails being sent and so on. Only POST and PATCH may have such side-effects. When e.g. a deletion of an activation needs to, say, notify users over mail, DELETE is not the right choice; in that case you probably want to create a deactivation resource: POST /groups/{group_id}/deactivation.

It is a good idea to follow these guidelines, because this standard contract makes it very clear for your clients, and all the proxies and layers between the client and you, know when it is safe to retry, and when not. Let's say the client is somewhere with flaky wifi, and its user clicks on "deactivate", which triggers a DELETE: If that fails, the client can simply retry, until it gets a 404, 200 or anything else it can handle. But if it triggers a POST to deactivation it knows not to retry: the POST implies this.
Any client now has a contract, which, when followed, will protect against sending out 42 emails "your group has been deactivated", simply because its HTTP-library kept retrying the call to the backend.

Updating a single attribute: use PATCH

PATCH /groups/{group id}

In case you wish to update an attribute. E.g. the "status" could be an attribute on Groups that can be set. An attribute such as "status" is often a good candidate to limit to a whitelist of values. Examples use some undefined JSON-scheme:

PATCH /groups/{group id} { "attributes": { "status": "active" } }
response: 200 OK

PATCH /groups/{group id} { "attributes": { "status": "deleted" } }
response: 406 Not Acceptable

Replacing the resource, without side-effects use PUT.

PUT /groups/{group id}

In case you wish to replace an entire Group. This does not necessarily mean that the server actually creates a new group and throws the old one out, e.g. the ids might remain the same. But for the clients, this is what PUT can mean: the client should assume he gets an entirely new item, based on the server's response.

The client should, in case of a PUT request, always send the entire resource, having all the data that is needed to create a new item: usually the same data as a POST-create would require.

PUT /groups/{group id} { "attributes": { "status": "active" } }
response: 406 Not Acceptable

PUT /groups/{group id} { "attributes": { "name": .... etc. "status": "active" } }
response: 201 Created or 200 OK, depending on whether we made a new one.

A very important requirement is that PUT is idempotent: if you require side-effects when updating a Group (or changing an activation), you should use PATCH. So, when the update results in e.g. sending out a mail, don't use PUT.

It's because you've removed the id which is how you're finding the element. This line of code is trying to add id="page_navigation1" to an element with the id named page_navigation1, but it doesn't exist (because you deleted the attribute):

$("#page_navigation1").attr("id","page_navigation1");

Demo:

If you want to add and remove a class that makes your <div> red use:

$( '#page_navigation1' ).addClass( 'red-class' );

And:

$( '#page_navigation1' ).removeClass( 'red-class' );

Where red-class is:

.red-class {
    background-color: red;
}

select * from (select name, ID from Empoyee) Visits
    pivot(sum(ID) for name
    in ([Emp1],
    [Emp2],
    [Emp3]
    ) ) as pivottable;

It is returning the array, but all returning something (including an Array) does is just what it sounds like: returns the value. In your case, you are getting the value of numbers(), which happens to be an array (it could be anything and you would still have this issue), and just letting it sit there.

When a function returns anything, it is essentially replacing the line in which it is called (in your case: numbers();) with the return value. So, what your main method is really executing is essentially the following:

public static void main(String[] args) {
    {1,2,3};
}

Which, of course, will appear to do nothing. If you wanted to do something with the return value, you could do something like this:

public static void main(String[] args){
    int[] result = numbers();
    for (int i=0; i<result.length; i++) {
        System.out.print(result[i]+" ");
    }
}

Why don't you simply move the code you have in the ApiController calls - DocumentsController to a class that you can call from both your HomeController and DocumentController. Pull this out into a class you call from both controllers. This stuff in your question:

// All code to find the files are here and is working perfectly...

It doesn't make sense to call a API Controller from another controller on the same website.

This will also simplify the code when you come back to it in the future you will have one common class for finding the files and doing that logic there...

Layout or view to bitmap:

 private Bitmap createBitmapFromLayout(View tv) {      
    int spec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
    tv.measure(spec, spec);
    tv.layout(0, 0, tv.getMeasuredWidth(), tv.getMeasuredHeight());
    Bitmap b = Bitmap.createBitmap(tv.getMeasuredWidth(), tv.getMeasuredWidth(),
            Bitmap.Config.ARGB_8888);
    Canvas c = new Canvas(b);
    c.translate((-tv.getScrollX()), (-tv.getScrollY()));
    tv.draw(c);
    return b;
}

Calling Method:

Bitmap src = createBitmapFromLayout(View.inflate(this, R.layout.sample, null)/* or pass your view object*/);

I find it more convenient to make a connection using a procedural programming language (like Python) and do these types of queries.

import psycopg2
connection_psql = psycopg2.connect( user="admin_user"
                                  , password="***"
                                  , port="5432"
                                  , database="myDB"
                                  , host="[ENDPOINT]")
cursor_psql = connection_psql.cursor()

myList = [...]
for item in myList:
  cursor_psql.execute('''
    -- The query goes here
  ''')

connection_psql.commit()
cursor_psql.close()

If you need to focus some textbox and your only problem is that the entire text gets highlighted whereas you want the caret to be at the end, then in that specific case, you can use this trick of setting the textbox value to itself after focus:

$("#myinputfield").focus().val($("#myinputfield").val());

To sort a dictionary and keep it functioning as a dictionary afterwards, you could use OrderedDict from the standard library.

If that's not what you need, then I encourage you to reconsider the sort functions that leave you with a list of tuples. What output did you want, if not an ordered list of key-value pairs (tuples)?

Also, the apt-show-versions package (installed separately) parses dpkg information about what is installed and tells you if packages are up to date.

A slightly prettier function based on Ansgar Wiechers's answer. Whether it's actually more useful is a matter of debate.

function Read-Choice(
   [Parameter(Mandatory)][string]$Message,
   [Parameter(Mandatory)][string[]]$Choices,
   [Parameter(Mandatory)][string]$DefaultChoice,
   [Parameter()][string]$Question='Are you sure you want to proceed?'
) {
    $defaultIndex = $Choices.IndexOf($DefaultChoice)
    if ($defaultIndex -lt 0) {
        throw "$DefaultChoice not found in choices"
    }

    $choiceObj = New-Object Collections.ObjectModel.Collection[Management.Automation.Host.ChoiceDescription]

    foreach($c in $Choices) {
        $choiceObj.Add((New-Object Management.Automation.Host.ChoiceDescription -ArgumentList $c))
    }

    $decision = $Host.UI.PromptForChoice($Message, $Question, $choiceObj, $defaultIndex)
    return $Choices[$decision]
}

Example usage:

PS> $r = Read-Choice 'DANGER!!!!!!' '&apple','&blah','&car' '&blah'

DANGER!!!!!!
Are you sure you want to proceed?
[A] apple  [B] blah  [C] car  [?] Help (default is "B"): c
PS> switch($r) { '&car' { Write-host 'caaaaars!!!!' } '&blah' { Write-Host "It's a blah day" } '&apple' { Write-Host "I'd like to eat some apples!" } }
caaaaars!!!!

Ignore this answer for now. The other answers, particularly that of aix, are mostly correct. Over the long term they're the way to bet. And if you have enough data (on one benchmark on one machine, it seemed to be about one million entries) ArrayList and LinkedList do currently work as advertized. However, there are some fine points that apply in the early 21st century.

Modern computer technology seems, by my testing, to give an enormous edge to arrays. Elements of an array can be shifted and copied at insane speeds. As a result arrays and ArrayList will, in most practical situations, outperform LinkedList on inserts and deletes, often dramatically. In other words, ArrayList will beat LinkedList at its own game.

The downside of ArrayList is it tends to hang onto memory space after deletions, where LinkedList gives up space as it gives up entries.

The bigger downside of arrays and ArrayList is they fragment free memory and overwork the garbage collector. As an ArrayList expands, it creates new, bigger arrays, copies the old array to the new one, and frees the old one. Memory fills with big contiguous chunks of free memory that are not big enough for the next allocation. Eventually there's no suitable space for that allocation. Even though 90% of memory is free, no individual piece is big enough to do the job. The GC will work frantically to move things around, but if it takes too long to rearrange the space, it will throw an OutOfMemoryException. If it doesn't give up, it can still slow your program way down.

The worst of it is this problem can be hard to predict. Your program will run fine one time. Then, with a bit less memory available, with no warning, it slows or stops.

LinkedList uses small, dainty bits of memory and GC's love it. It still runs fine when you're using 99% of your available memory.

So in general, use ArrayList for smaller sets of data that are not likely to have most of their contents deleted, or when you have tight control over creation and growth. (For instance, creating one ArrayList that uses 90% of memory and using it without filling it for the duration of the program is fine. Continually creating and freeing ArrayList instances that use 10% of memory will kill you.) Otherwise, go with LinkedList (or a Map of some sort if you need random access). If you have very large collections (say over 100,000 elements), no concerns about the GC, and plan lots of inserts and deletes and no random access, run a few benchmarks to see what's fastest.

Extracting a specific folder (directory) within war file:

# unzip <war file> '<folder to extract/*>' -d <destination path> 
unzip app##123.war 'some-dir/*' -d extracted/

You get ./extracted/some-dir/ as a result.

You can use this code if you have a bunch of hosts in text file

$a = get-content "C:\Users\host.txt"(file path) 

foreach ($i in $a )
    {
$i + "`n" + "==========================";[System.Net.Dns]::GetHostAddresses($i) 

}

Here's another solution: http://jsfiddle.net/6WvUY/7/.

HTML:

<div class="container">
    <div class="row">
        <div class="col-sm-6">
            <img src="//placehold.it/600x300" alt="Logo" class="img-responsive"/>
        </div>
        <div class="col-sm-6">

        </div>
    </div>
</div>

CSS:

.row {
    display: table;
}

.row > div {
    float: none;
    display: table-cell;
}

1. check the @viewchild in your .ts

   @ViewChild('ngOtpInput') ngOtpInput:any;
   

2. set the below code in your method were you want the fields to be clear.

   yourMethod(){
       this.ngOtpInput.setValue(yourValue);
   }
   

The problem lays here:

--This result set has 3 columns
select LOC_id,LOC_locatie,LOC_deelVan_LOC_id from tblLocatie t
where t.LOC_id = 1 -- 1 represents an example

union all

--This result set has 1 columns   
select t.LOC_locatie + '>' from tblLocatie t
inner join q parent on parent.LOC_id = t.LOC_deelVan_LOC_id

In order to use union or union all number of columns and their types should be identical cross all result sets.

I guess you should just add the column LOC_deelVan_LOC_id to your second result set

Note that $(element).offset() tells you the position of an element relative to the document. This works great in most circumstances, but in the case of position:fixed you can get unexpected results.

If your document is longer than the viewport and you have scrolled vertically toward the bottom of the document, then your position:fixed element's offset() value will be greater than the expected value by the amount you have scrolled.

If you are looking for a value relative to the viewport (window), rather than the document on a position:fixed element, you can subtract the document's scrollTop() value from the fixed element's offset().top value. Example: $("#el").offset().top - $(document).scrollTop()

If the position:fixed element's offset parent is the document, you want to read parseInt($.css('top')) instead.

In order for the client to be able to read cookies from cross-origin requests, you need to have:

1. All responses from the server need to have the following in their header:

   Access-Control-Allow-Credentials: true

2. The client needs to send all requests with withCredentials: true option

In my implementation with Angular 7 and Spring Boot, I achieved that with the following:

@CrossOrigin(origins = "http://my-cross-origin-url.com", allowCredentials = "true")
@Controller
@RequestMapping(path = "/something")
public class SomethingController {
  ...
}

The origins = "http://my-cross-origin-url.com" part will add Access-Control-Allow-Origin: http://my-cross-origin-url.com to every server's response header

The allowCredentials = "true" part will add Access-Control-Allow-Credentials: true to every server's response header, which is what we need in order for the client to read the cookies

Client-side:

import { HttpInterceptor, HttpXsrfTokenExtractor, HttpRequest, HttpHandler, HttpEvent } from "@angular/common/http";
import { Injectable } from "@angular/core";
import { Observable } from 'rxjs';

@Injectable()
export class CustomHttpInterceptor implements HttpInterceptor {

    constructor(private tokenExtractor: HttpXsrfTokenExtractor) {
    }

    intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
        // send request with credential options in order to be able to read cross-origin cookies
        req = req.clone({ withCredentials: true });

        // return XSRF-TOKEN in each request's header (anti-CSRF security)
        const headerName = 'X-XSRF-TOKEN';
        let token = this.tokenExtractor.getToken() as string;
        if (token !== null && !req.headers.has(headerName)) {
            req = req.clone({ headers: req.headers.set(headerName, token) });
        }
        return next.handle(req);
    }
}

With this class you actually inject additional stuff to all your request.

The first part req = req.clone({ withCredentials: true });, is what you need in order to send each request with withCredentials: true option. This practically means that an OPTION request will be send first, so that you get your cookies and the authorization token among them, before sending the actual POST/PUT/DELETE requests, which need this token attached to them (in the header), in order for the server to verify and execute the request.

The second part is the one that specifically handles an anti-CSRF token for all requests. Reads it from the cookie when needed and writes it in the header of every request.

The desired result is something like this:

For sending mails using php mail function is used. But mail function requires SMTP server for sending emails. we need to mention SMTP host and SMTP port in php.ini file. Upon successful configuration of SMTP server mails will be sent successfully sent through php scripts.

I got the same issue and this solved it for me. Perhaps this might be a fix for your problem too.

Here is the fix. Follow this link http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/

Go to "Fixed curl extensions" and download the extension that matches your PHP version.

Extract and copy "php_curl.dll" to the extension directory of your wamp installation. (i.e. C:\wamp\bin\php\php5.3.13\ext)

Restart Apache

Done!

Refer to: http://blog.nterms.com/2012/07/php-curl-issues-with-wamp-server-on.html

As soon as you're displaying content from another domain, you're basically trusting that domain not to serve-up malware.

There's nothing wrong with iframes per se. If you control the content of the iframe, they're perfectly safe.

Depending on the Tkinter activity, and especially when using Tkinter.after, stopping this activity with destroy() -- even by using protocol(), a button, etc. -- will disturb this activity ("while executing" error) rather than just terminate it. The best solution in almost every case is to use a flag. Here is a simple, silly example of how to use it (although I am certain that most of you don't need it! :)

from Tkinter import *

def close_window():
  global running
  running = False  # turn off while loop
  print( "Window closed")

root = Tk()
root.protocol("WM_DELETE_WINDOW", close_window)
cv = Canvas(root, width=200, height=200)
cv.pack()

running = True;
# This is an endless loop stopped only by setting 'running' to 'False'
while running: 
  for i in range(200): 
    if not running: 
        break
    cv.create_oval(i, i, i+1, i+1)
    root.update() 

This terminates graphics activity nicely. You only need to check running at the right place(s).

Java 8 is in the market after almost 2 decades, following is the way to iterate org.json.JSONArray with java8 Stream API.

import org.json.JSONArray;
import org.json.JSONObject;

@Test
public void access_org_JsonArray() {
    //Given: array
    JSONArray jsonArray = new JSONArray(Arrays.asList(new JSONObject(
                    new HashMap() {{
                        put("a", 100);
                        put("b", 200);
                    }}
            ),
            new JSONObject(
                    new HashMap() {{
                        put("a", 300);
                        put("b", 400);
                    }}
            )));

    //Then: convert to List<JSONObject>
    List<JSONObject> jsonItems = IntStream.range(0, jsonArray.length())
            .mapToObj(index -> (JSONObject) jsonArray.get(index))
            .collect(Collectors.toList());

    // you can access the array elements now
    jsonItems.forEach(arrayElement -> System.out.println(arrayElement.get("a")));
    // prints 100, 300
}

If the iteration is only one time, (no need to .collect)

    IntStream.range(0, jsonArray.length())
            .mapToObj(index -> (JSONObject) jsonArray.get(index))
            .forEach(item -> {
               System.out.println(item);
            });

I had the exact same issue and it boiled down to an unmet dependency, however, I tried the accepted answer's solution and it did not work.

What finally worked for me was installing all of the following (this is RedHat):

sudo yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel

Afterwards, I ran the other commands as specified and it worked:

./configure
make
sudo make prefix=/usr/local install

I pulled the list of dependencies directly from Git's website. Apparently I should have started there :/

You need to add:

 #include <cstdlib>

in order for the compiler to see the prototype for system().

The var_dump function displays structured information about variables/expressions including its type and value. Arrays are explored recursively with values indented to show structure. It also shows which array values and object properties are references.

The print_r() displays information about a variable in a way that's readable by humans. array values will be presented in a format that shows keys and elements. Similar notation is used for objects.

Example:

$obj = (object) array('qualitypoint', 'technologies', 'India');

var_dump($obj) will display below output in the screen.

object(stdClass)#1 (3) {
 [0]=> string(12) "qualitypoint"
 [1]=> string(12) "technologies"
 [2]=> string(5) "India"
}

And, print_r($obj) will display below output in the screen.

stdClass Object ( 
 [0] => qualitypoint
 [1] => technologies
 [2] => India
)

More Info

• var_dump
• print_r

Yes, but not with that version of the constructor. You can do this:

>>> dict([(1, 2), (3, 4)])
{1: 2, 3: 4}

There are several different ways to make a dict. As documented, "providing keyword arguments [...] only works for keys that are valid Python identifiers."

You just need to make the siprimo and volteado methods static.

private static bool siprimo(long a)

and

private static long volteado(long a)

What if you have your data in CSV format and convert it to HTML for display on the web page? You may use the http://code.google.com/p/js-tables/ plugin. Check this example http://code.google.com/p/js-tables/wiki/Table As you are already using jQuery library I have assumed you are able to add other javascript toolkit libraries.

If the data is in CSV format, you should be able to use the generic 'application/octetstream' mime type. All the 3 mime types you have tried are dependent on the software installed on the clients computer.

Since you already seem to have solved the basic pointer address display, here's how you would check the address of a double pointer:

char **a;
char *b;
char c = 'H';

b = &c;
a = &b;

You would be able to access the address of the double pointer a by doing:

printf("a points at this memory location: %p", a);
printf("which points at this other memory location: %p", *a);

It's really simple,just add image to background of you button and give text to titlelabel of button for uicontrolstatenormal. That's it.

[btn setBackgroundImage:[UIImage imageNamed:@"img.png"] forState:UIControlStateNormal];
[btn setContentVerticalAlignment:UIControlContentVerticalAlignmentBottom];
[btn setTitle:@"Click Me" forState:UIControlStateNormal];

UPDATE 2: This information is no more given by facebook. There is an official announcement for the behavior change (https://developers.facebook.com/blog/post/2018/04/19/facebook-login-changes-address-abuse/) but none for its alternative.

Yes, Just use this link and append your ID to the id parameter:

https://facebook.com/profile.php?id=<UID>

So for example:

https://facebook.com/profile.php?id=4

Will redirect you automatically to https://www.facebook.com/zuck Which is Mark Zuckerberg's profile.

If you want to do this for all your ids, then you can do it using a loop.

If you'd like, I can provide you with a snippet.

UPDATE: Alternatively, You can also do this:

https://facebook.com/<UID>

So that would be: https://facebook.com/4 which would automatically redirect to Zuck!

use the following

select sum(transaction_amount) from TransactionMaste
where Card_No = '123' and transaction_date = CONVERT(VARCHAR(10),GETDATE(),111)

or the following

select sum(transaction_amount) from TransactionMaste
where Card_No = '123' and transaction_date = CONVERT(VARCHAR(10), GETDATE(), 120)

As already stated this is not something that browsers support.

If you aren't coming up with the styles dynamically (i.e. pulling them out of a database or something) you should be able to work around this by adding a class to the body of the page.

The css would look something like:

a:hover { background: red; }
.theme1 a:hover { background: blue; }

And the javascript to change this would be something like:

// Look up some good add/remove className code if you want to do this
// This is really simplified

document.body.className += " theme1";  

import socket
from threading import *

serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host = "192.168.1.3"
port = 8000
print (host)
print (port)
serversocket.bind((host, port))

class client(Thread):
    def __init__(self, socket, address):
        Thread.__init__(self)
        self.sock = socket
        self.addr = address
        self.start()

    def run(self):
        while 1:
            print('Client sent:', self.sock.recv(1024).decode())
            self.sock.send(b'Oi you sent something to me')

serversocket.listen(5)
print ('server started and listening')
while 1:
    clientsocket, address = serversocket.accept()
    client(clientsocket, address)

This is a very VERY simple design for how you could solve it. First of all, you need to either accept the client (server side) before going into your while 1 loop because in every loop you accept a new client, or you do as i describe, you toss the client into a separate thread which you handle on his own from now on.

Add .+? in <[^>]*> and try this regex (base on this):

yes block are the most used functionality , so in order to avoid the retain cycle we should avoid using the strong variable,including self inside the block, inspite use the _weak or weakself.

That number indicates Date and Time Styles

You need to look at CAST and CONVERT (Transact-SQL). Here you can find the meaning of all these Date and Time Styles.

Styles with century (e.g. 100, 101 etc) means year will come in yyyy format. While styles without century (e.g. 1,7,10) means year will come in yy format.

You can also refer to SQL Server Date Formats. Here you can find all date formats with examples.

It's possible to debug JavaScript by setting breakpoints in Eclipse using the AJAX Tools Framework.

I just came across the same problem, and the simplest solution I found was to use SSH URL instead of HTTPS one:

ssh://[email protected]/username/repo.git

And not this:

https://github.com/username/repo.git

You can now validate with just the SSH key instead of the username and password.

Setting expect 100 continue to false and reducing the socket idle time to two seconds resolved the problem for me

ServicePointManager.Expect100Continue = false; 
ServicePointManager. MaxServicePointIdleTime = 2000; 

JSON only allows key names to be strings. Those strings can consist of numerical values.

You aren't using JSON though. You have a JavaScript object literal. You can use identifiers for keys, but an identifier can't start with a number. You can still use strings though.

var Game={
    "status": [
        {
            "0": "val",
            "1": "val",
            "2": "val"
        },
        {
            "0": "val",
            "1": "val",
            "2": "val"
        }
    ]
}

If you access the properties with dot-notation, then you have to use identifiers. Use square bracket notation instead: Game.status[0][0].

But given that data, an array would seem to make more sense.

var Game={
    "status": [
        [
            "val",
            "val",
            "val"
        ],
        [
            "val",
            "val",
            "val"
        ]
    ]
}

the problem's actually caused by dependency. I spent whole the day to solve this prblm. Firstly, right click on project > Maven > add dependency

In "EnterGroupId, ArtifactId, or sha1...." box, type "org.springframework".

Then, from droped down list, expand "spring-web" list > Choose the newest version of jar file > Click OK.
Done!!!

if its numerically indexed:

foreach ($foo as $key=>$var){

    if($var==$foo[$key+1]){
        echo 'current and next var are the same';
    }
}

You can do it with a LIMIT, just not with a LIMIT and an OFFSET.

hope this help you or Ctrl + Alt + Shift + S => select Dependencies tab and find what you need ( see my image)

<context:component-scan base-package="x.y.z"/>

will work since the rest of the packages are sub packages of "x.y.z". Thus, you dont need to mention each package individually.

Use the number_format() function to change how a number is displayed. It will return a string, the type of the original variable is unaffected.

Check your id. Is it Identity? If it is then make sure it is declared as ID not null Identity(1,1)

And before creating your table , Drop table and then create table.

To augment T.J.'s answer, exceeding the min/max values generates an Invalid Date.

let maxDate = new Date(8640000000000000);_x000D_
let minDate = new Date(-8640000000000000);_x000D_
_x000D_
console.log(new Date(maxDate.getTime()).toString());_x000D_
console.log(new Date(maxDate.getTime() - 1).toString());_x000D_
console.log(new Date(maxDate.getTime() + 1).toString()); // Invalid Date_x000D_
_x000D_
console.log(new Date(minDate.getTime()).toString());_x000D_
console.log(new Date(minDate.getTime() + 1).toString());_x000D_
console.log(new Date(minDate.getTime() - 1).toString()); // Invalid Date

you can declare a Numpy array dynamically for 1 dimension as shown below:

import numpy as np

n = 2
new_table = np.empty(shape=[n,1])

new_table[0,0] = 2
new_table[1,0] = 3
print(new_table)

The above example assumes we know we need to have 1 column but we want to allocate the number of rows dynamically (in this case the number or rows required is equal to 2)

output is shown below:

[[2.] [3.]]

if location == a2:
    img = Image.open("picture.jpg")
    Img.show

Make sure the name of the image is in parantheses this should work

In general, in C++ functions have to be declared before you call them. So sometime before the definition of getSkewNormal(), the compiler needs to see the declaration:

double integrate (double start, double stop, int numSteps, Evaluatable evalObj);

Mostly what people do is put all the declarations (only) in the header file, and put the actual code -- the definitions of the functions and methods -- into a separate source (*.cc or *.cpp) file. This neatly solves the problem of needing all the functions to be declared.

Two solutions: 1- if the type of the target column is [nvarchar] it should be change to [varchar]

2- Add a "Derived Column" component to the SSIS package and add a new column with the following expression:
(DT_WSTR, «length») [ColumnName]

Length is the length of the column in the target table and ColumnName is the name of the column in the target table. finally at the mapping part you should use this new added column instead of the original column.

i had this problem when running the magento indexer in osx. and yes its related to php problem when connecting to mysql through pdo

in mac osx xampp, to fix this you have create symbolic link to directory /var/mysql, here is how

cd /var/mysql && sudo ln -s /Applications/XAMPP/xamppfiles/var/mysql/mysql.sock

if the directory /var/mysql doesnt exist, we must create it with

sudo mkdir /var/mysql

I combined two answers (@bviktor and @jocassid). It was tested on Windows 10 and Windows Server 2012.

function New-SymLink ($link, $target)
{
    if ($PSVersionTable.PSVersion.Major -ge 5)
    {
        New-Item -Path $link -ItemType SymbolicLink -Value $target
    }
    else
    {
        $command = "cmd /c mklink /d"
        invoke-expression "$command ""$link"" ""$target"""
    }
}

If you have arrived here via google, please make sure to check that you have given self as the first parameter to a class function. Especially if you try to reference values for that object instance inside the class function.

The accepted answer of using npm-install-peers did not work, nor removing node_modules and rebuilding. The answer to run

npm install --save-dev @xxxxx/xxxxx@latest

for each one, with the xxxxx referring to the exact text in the peer warning, worked. I only had four warnings, if I had a dozen or more as in the question, it might be a good idea to script the commands.

For beginners, I wanted to add to the accepted answer, because a couple of subtleties were unclear to me:

To find and modify text (not completely replace),

1. In the "Find" step, you can use regex with "capturing groups," e.g. your search could be la la la (group1) blah blah (group2), using parentheses.

2. And then in the "Replace" step, you can refer to the capturing groups via $1, $2 etc.

So, for example, in this case we could find the relevant text with just <h1>.+?<\/h1> (no parentheses), but putting in the parentheses <h1>(.+?)<\/h1> allows us to refer to the sub-match in between them as $1 in the replace step. Cool!

Notes

• To turn on Regex in the Find Widget, click the .* icon, or press Cmd/Ctrl Alt R

• $0 refers to the whole match

• Finally, the original question states that the replace should happen "within a document," so you can use the "Find Widget" (Cmd or Ctrl + F), which is local to the open document, instead of "Search", which opens a bigger UI and looks across all files in the project.

Yes, you can access it through GET and POST (trying this simple task would have made you aware of that).

Yes, there are other ways, one of the other "preferred" ways is using sessions. When you would want to use hidden over session is kind of touchy, but any GET / POST data is easily manipulated by the end user. A session is a bit more secure given it is saved to a file on the server and it is much harder for the end user to manipulate without access through the program.

FWIW I had this same issue. Turned out my xsi:schemaLocation entries were incorrect, so I went to the official docs and pasted theirs into mine:

http://docs.spring.io/spring/docs/current/spring-framework-reference/html/transaction.html section 16.5.6

I had to add a couple more but that was ok. Next up is to find out why this fixed the problem...

If you guys are generating your stylesheets with LESS/SASS and are importing Bootstrap there, I've found that overriding the @navbar-height variable lets your set the height of the navbar, which is originally defined in the variables.less file.

you can change firstItem to id and it will work

you can change the routing on global.asax (i do not recommed that)

and, can't believe no one mentioned this, you can call :

http://localhost:2316/Inventory/ViewStockNext?firstItem=11

In a @Url.Action would be :

@Url.Action("ViewStockNext", "Inventory", new {firstItem=11});

depending on the type of what you are doing, the last will be more suitable. Also you should consider not doing ViewStockNext action and instead a ViewStock action with index. (my 2cents)

I face the same problem and changing

 $cfg['Servers'][$i]['host'] = 'localhost';

to

 $cfg['Servers'][$i]['host'] = '127.0.0.1';

Solved this issue.

Here's Jeanne's lovely answer, but wrapped in a tidy function for muppets like me:

private static String getUrl(String aUrl) throws MalformedURLException, IOException
{
    String urlData = "";
    URL urlObj = new URL(aUrl);
    URLConnection conn = urlObj.openConnection();
    try (BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream(), StandardCharsets.UTF_8))) 
    {
        urlData = reader.lines().collect(Collectors.joining("\n"));
    }
    return urlData;
}

bool isFirst = compareString.Contains(firstString);
bool isSecond = compareString.Contains(secondString );

In a hacky way it can be done for channels which one attempts to write to by recovering the raised panic. But you cannot check if a read channel is closed without reading from it.

Either you will

• eventually read the "true" value from it (v <- c)
• read the "true" value and 'not closed' indicator (v, ok <- c)
• read a zero value and the 'closed' indicator (v, ok <- c)
• will block in the channel read forever (v <- c)

Only the last one technically doesn't read from the channel, but that's of little use.

eloone did it file by file with

git checkout <commit-hash> <filename>

but you could checkout all files more easily by doing

git checkout <commit-hash> .

Two ways to do that..

Option 1:

1.  Go to "Start" -> "Run".

2.  Write "CMD" and press on "Enter" key.

3.  Write the command "net statistics server" and press on "Enter" key.

4.  The line that start with "Statistics since …" provides the time that the server was up from.


  The command "net stats srv" can be use instead.

Option 2:

A sed script that will only replace the first occurrence of "Apple" by "Banana"

Example

     Input:      Output:

     Apple       Banana
     Apple       Apple
     Orange      Orange
     Apple       Apple

This is the simple script: ^{Editor's note: works with GNU sed only.}

sed '0,/Apple/{s/Apple/Banana/}' input_filename

The first two parameters 0 and /Apple/ are the range specifier. The s/Apple/Banana/ is what is executed within that range. So in this case "within the range of the beginning (0) up to the first instance of Apple, replace Apple with Banana. Only the first Apple will be replaced.

Background: In traditional sed the range specifier is also "begin here" and "end here" (inclusive). However the lowest "begin" is the first line (line 1), and if the "end here" is a regex, then it is only attempted to match against on the next line after "begin", so the earliest possible end is line 2. So since range is inclusive, smallest possible range is "2 lines" and smallest starting range is both lines 1 and 2 (i.e. if there's an occurrence on line 1, occurrences on line 2 will also be changed, not desired in this case). GNU sed adds its own extension of allowing specifying start as the "pseudo" line 0 so that the end of the range can be line 1, allowing it a range of "only the first line" if the regex matches the first line.

Or a simplified version (an empty RE like // means to re-use the one specified before it, so this is equivalent):

sed '0,/Apple/{s//Banana/}' input_filename

And the curly braces are optional for the s command, so this is also equivalent:

sed '0,/Apple/s//Banana/' input_filename

All of these work on GNU sed only.

You can also install GNU sed on OS X using homebrew brew install gnu-sed.

Starting with Oracle 12c there is support for Identity columns in one of two ways:

1. Sequence + Table - In this solution you still create a sequence as you normally would, then you use the following DDL:

   CREATE TABLE MyTable (ID NUMBER DEFAULT MyTable_Seq.NEXTVAL, ...)

2. Table Only - In this solution no sequence is explicitly specified. You would use the following DDL:

   CREATE TABLE MyTable (ID NUMBER GENERATED AS IDENTITY, ...)

If you use the first way it is backward compatible with the existing way of doing things. The second is a little more straightforward and is more inline with the rest of the RDMS systems out there.

In your router.php file, you should use the model class like this

 use App\Post;

and use the model class like this.

Route::get('/posts', function() {

        $results = Post::all();
        return $results; });

In a node.js server console.log outputs to the terminal window, not to the browser's console window.

How are you running your server? You should see the output directly after you start it.

I found two solutions at the jQuery's documentation:

First: Use delegate on Body or Document

E.g:

 $("body").delegate('.test', 'click', function(){
 ...
  alert('test');
 });

Why?

Answer: Attach a handler to one or more events for all elements that match the selector, now or in the future, based on a specific set of root elements. link: http://api.jquery.com/delegate/

Second: Put the your function at the "$( document )", using "on" and attach it to the element that you want to trigger this. The first parameter is the "event handler", the second: the element and the third: the function. E.g:

 $( document ).on( 'click', '.test', function () {
 ...
  alert('test');
 });

Why?

Answer: Event handlers are bound only to the currently selected elements; they must exist on the page at the time your code makes the call to .on(). To ensure the elements are present and can be selected, perform event binding inside a document ready handler for elements that are in the HTML markup on the page. If new HTML is being injected into the page, select the elements and attach event handlers after the new HTML is placed into the page. Or, use delegated events to attach an event handler, as described next ... link: https://api.jquery.com/on/

I had a similar problem, I tried to clear all the caches possible (tried almost all the solutions above) and the only thing that worked for me was to kill the expo app and to restart it.

You do not need to use docker run.

You can do it with docker create.

From the docs:

The docker create command creates a writeable container layer over the specified image and prepares it for running the specified command. The container ID is then printed to STDOUT. This is similar to docker run -d except the container is never started.

So, you can do:

docker create -ti --name dummy IMAGE_NAME bash
docker cp dummy:/path/to/file /dest/to/file
docker rm -f dummy

Here, you never start the container. That looked beneficial to me.

The following example for complex numbers should be self explanatory including the error message at the end

>>> x=complex(1,2)
>>> print x
(1+2j)
>>> y=complex(3,4)
>>> print y
(3+4j)
>>> z=x+y
>>> print x
(1+2j)
>>> print z
(4+6j)
>>> z=x*y
>>> print z
(-5+10j)
>>> z=x/y
>>> print z
(0.44+0.08j)
>>> print x.conjugate()
(1-2j)
>>> print x.imag
2.0
>>> print x.real
1.0
>>> print x>y

Traceback (most recent call last):
  File "<pyshell#149>", line 1, in <module>

TypeError: no ordering relation is defined for complex numbers
>>> print x==y

Sure, you can use JS's foreach.

for (var k in result) {
  something(result[k])
}

On Windows you can try these steps:

1. Download a root CA certificate from the website.
2. Find a file jssecacerts in the directory /lib/security with JRE (you can use a comand System.out.println(System.getProperty("java.home"); to find the folder with the current JRE). Make a backup of the file.
3. Download a program portecle.
4. Open the jssecacerts file in portecle.
5. Enter the password: changeit.
6. Import the downloaded certificate with porticle (Tools > Import Trusted Certificate).
7. Click Save.
8. Replace the original file jssecacerts.

When you build your assembly, you can call AssemblyBuilder.SetEntryPoint, and then get it back from the Assembly.EntryPoint property to invoke it.

Keep in mind you'll want to use this signature, and note that it doesn't have to be named Main:

static void Run(string[] args)

For large dataframes of numeric data, you may see a significant performance improvement via numpy.lexsort, which performs an indirect sort using a sequence of keys:

import pandas as pd
import numpy as np

np.random.seed(0)

df1 = pd.DataFrame(np.random.randint(1, 5, (10,2)), columns=['a','b'])
df1 = pd.concat([df1]*100000)

def pdsort(df1):
    return df1.sort_values(['a', 'b'], ascending=[True, False])

def lex(df1):
    arr = df1.values
    return pd.DataFrame(arr[np.lexsort((-arr[:, 1], arr[:, 0]))])

assert (pdsort(df1).values == lex(df1).values).all()

%timeit pdsort(df1)  # 193 ms per loop
%timeit lex(df1)     # 143 ms per loop

One peculiarity is that the defined sorting order with numpy.lexsort is reversed: (-'b', 'a') sorts by series a first. We negate series b to reflect we want this series in descending order.

Be aware that np.lexsort only sorts with numeric values, while pd.DataFrame.sort_values works with either string or numeric values. Using np.lexsort with strings will give: TypeError: bad operand type for unary -: 'str'.

You can access the index attribute of a df using .index:

In [277]:

df = pd.DataFrame({'a':np.arange(10), 'b':np.random.randn(10)})
df
Out[277]:
   a         b
0  0  0.293422

The following C++ implementation includes also some code that builds the actual longest increasing subsequence using an array called prev.

std::vector<int> longest_increasing_subsequence (const std::vector<int>& s)
{
    int best_end = 0;
    int sz = s.size();

    if (!sz)
        return std::vector<int>();

    std::vector<int> prev(sz,-1);
    std::vector<int> memo(sz, 0);

    int max_length = std::numeric_limits<int>::min();

    memo[0] = 1;

    for ( auto i = 1; i < sz; ++i)
    {
        for ( auto j = 0; j < i; ++j)
        {
            if ( s[j] < s[i] && memo[i] < memo[j] + 1 )
            {
                memo[i] =  memo[j] + 1;
                prev[i] =  j;
            }
        }

        if ( memo[i] > max_length ) 
        {
            best_end = i;
            max_length = memo[i];
        }
    }

    // Code that builds the longest increasing subsequence using "prev"
    std::vector<int> results;
    results.reserve(sz);

    std::stack<int> stk;
    int current = best_end;

    while (current != -1)
    {
        stk.push(s[current]);
        current = prev[current];
    }

    while (!stk.empty())
    {
        results.push_back(stk.top());
        stk.pop();
    }

    return results;
}

Implementation with no stack just reverse the vector

#include <iostream>
#include <vector>
#include <limits>
std::vector<int> LIS( const std::vector<int> &v ) {
  auto sz = v.size();
  if(!sz)
    return v;
  std::vector<int> memo(sz, 0);
  std::vector<int> prev(sz, -1);
  memo[0] = 1;
  int best_end = 0;
  int max_length = std::numeric_limits<int>::min();
  for (auto i = 1; i < sz; ++i) {
    for ( auto j = 0; j < i ; ++j) {
      if (s[j] < s[i] && memo[i] < memo[j] + 1) {
        memo[i] = memo[j] + 1;
        prev[i] = j;
      }
    }
    if(memo[i] > max_length) {
      best_end = i;
      max_length = memo[i];
    }
  }

  // create results
  std::vector<int> results;
  results.reserve(v.size());
  auto current = best_end;
  while (current != -1) {
    results.push_back(s[current]);
    current = prev[current];
  }
  std::reverse(results.begin(), results.end());
  return results;
}

I've a problem with H2 version 1.4.190 remote connection to inMemory (as well as in file) with Connection is broken: "unexpected status 16843008" until do not downgrade to 1.3.176. See Grails accessing H2 TCP server hangs

It looks like it only works in Internet Explorer, but a quick Google search for "html embed fonts" yields http://www.spoono.com/html/tutorials/tutorial.php?id=19

If you want to stay platform-agnostic (and you should!) you'll have to use images, or else just use a standard font.

Yes, you need the full path.

log = open(os.path.join(root, f), 'r')

Is the quick fix. As the comment pointed out, os.walk decends into subdirs so you do need to use the current directory root rather than indir as the base for the path join.

I've had a hard time with ssh2 in php mostly because the output stream sometimes works and sometimes it doesn't. I'm just gonna paste my lib here which works for me very well.

To much code, you can use it like this:

#include<array>
#include<functional>

int main()
{
    std::array<int, 10> vec = { 1,2,3,4,5,6,7,8,9 };

    std::sort(std::begin(vec), 
              std::end(vec), 
              [](int a, int b) {return a > b; });

    for (auto item : vec)
      std::cout << item << " ";

    return 0;
}

Replace "vec" with your class and that's it.

Well, this is my final solution for a simple db, for Linux:

# Read this before!
#
# * roles in postgres are users, and can be used also as group of users
# * $ROLE_LOCAL will be the user that access the db for maintenance and
#   administration. $ROLE_REMOTE will be the user that access the db from the webapp
# * you have to change '$ROLE_LOCAL', '$ROLE_REMOTE' and '$DB'
#   strings with your desired names
# * it's preferable that $ROLE_LOCAL == $DB

Introduction

You can get everything through ExternalContext. In JSF 1.x, you can get the raw HttpServletResponse object by ExternalContext#getResponse(). In JSF 2.x, you can use the bunch of new delegate methods like ExternalContext#getResponseOutputStream() without the need to grab the HttpServletResponse from under the JSF hoods.

On the response, you should set the Content-Type header so that the client knows which application to associate with the provided file. And, you should set the Content-Length header so that the client can calculate the download progress, otherwise it will be unknown. And, you should set the Content-Disposition header to attachment if you want a Save As dialog, otherwise the client will attempt to display it inline. Finally just write the file content to the response output stream.

Most important part is to call FacesContext#responseComplete() to inform JSF that it should not perform navigation and rendering after you've written the file to the response, otherwise the end of the response will be polluted with the HTML content of the page, or in older JSF versions, you will get an IllegalStateException with a message like getoutputstream() has already been called for this response when the JSF implementation calls getWriter() to render HTML.

Turn off ajax / don't use remote command!

You only need to make sure that the action method is not called by an ajax request, but that it is called by a normal request as you fire with <h:commandLink> and <h:commandButton>. Ajax requests and remote commands are handled by JavaScript which in turn has, due to security reasons, no facilities to force a Save As dialogue with the content of the ajax response.

In case you're using e.g. PrimeFaces <p:commandXxx>, then you need to make sure that you explicitly turn off ajax via ajax="false" attribute. In case you're using ICEfaces, then you need to nest a <f:ajax disabled="true" /> in the command component.

Generic JSF 2.x example

public void download() throws IOException {
    FacesContext fc = FacesContext.getCurrentInstance();
    ExternalContext ec = fc.getExternalContext();

    ec.responseReset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
    ec.setResponseContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ExternalContext#getMimeType() for auto-detection based on filename.
    ec.setResponseContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
    ec.setResponseHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.

    OutputStream output = ec.getResponseOutputStream();
    // Now you can write the InputStream of the file to the above OutputStream the usual way.
    // ...

    fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}

Generic JSF 1.x example

public void download() throws IOException {
    FacesContext fc = FacesContext.getCurrentInstance();
    HttpServletResponse response = (HttpServletResponse) fc.getExternalContext().getResponse();

    response.reset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
    response.setContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ServletContext#getMimeType() for auto-detection based on filename.
    response.setContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
    response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.

    OutputStream output = response.getOutputStream();
    // Now you can write the InputStream of the file to the above OutputStream the usual way.
    // ...

    fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}

Common static file example

In case you need to stream a static file from the local disk file system, substitute the code as below:

File file = new File("/path/to/file.ext");
String fileName = file.getName();
String contentType = ec.getMimeType(fileName); // JSF 1.x: ((ServletContext) ec.getContext()).getMimeType(fileName);
int contentLength = (int) file.length();

// ...

Files.copy(file.toPath(), output);

Common dynamic file example

In case you need to stream a dynamically generated file, such as PDF or XLS, then simply provide output there where the API being used expects an OutputStream.

E.g. iText PDF:

String fileName = "dynamic.pdf";
String contentType = "application/pdf";

// ...

Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, output);
document.open();
// Build PDF content here.
document.close();

E.g. Apache POI HSSF:

String fileName = "dynamic.xls";
String contentType = "application/vnd.ms-excel";

// ...

HSSFWorkbook workbook = new HSSFWorkbook();
// Build XLS content here.
workbook.write(output);
workbook.close();

Note that you cannot set the content length here. So you need to remove the line to set response content length. This is technically no problem, the only disadvantage is that the enduser will be presented an unknown download progress. In case this is important, then you really need to write to a local (temporary) file first and then provide it as shown in previous chapter.

Utility method

If you're using JSF utility library OmniFaces, then you can use one of the three convenient Faces#sendFile() methods taking either a File, or an InputStream, or a byte[], and specifying whether the file should be downloaded as an attachment (true) or inline (false).

public void download() throws IOException {
    Faces.sendFile(file, true);
}

Yes, this code is complete as-is. You don't need to invoke responseComplete() and so on yourself. This method also properly deals with IE-specific headers and UTF-8 filenames. You can find source code here.

You can use request-ip, to retrieve a user's ip address. It handles quite a few of the different edge cases, some of which are mentioned in the other answers.

Disclosure: I created this module

Install:

npm install request-ip

In your app:

var requestIp = require('request-ip');

// inside middleware handler
var ipMiddleware = function(req, res, next) {
    var clientIp = requestIp.getClientIp(req); // on localhost > 127.0.0.1
    next();
};

Hope this helps

if you want to populate contents of your partial view inside your view you can use

@Html.Partial("PartialViewName")

or

{@Html.RenderPartial("PartialViewName");}

if you want to make server request and process the data and then return partial view to you main view filled with that data you can use

...
    @Html.Action("Load", "Home")
...

public PartialViewResult Load()
{
    return PartialView("_LoadView");
}

if you want user to click on the link and then populate the data of partial view you can use:

@Ajax.ActionLink(
    "Click Here to Load the Partial View", 
    "ActionName", 
    "ControlerName",
    null, 
    new AjaxOptions { UpdateTargetId = "toUpdate" }
)

find -name "*Robert*" \( -name "*.pdf" -o -name "*.jpg" \)

The -o repreents an OR condition and you can add as many as you wish within the braces. So this says to find all files containing the word "Robert" anywhere in their names and whose names end in either "pdf" or "jpg".

You would normally use -stringWithFormat here.

NSString *myString = [NSString stringWithFormat:@"%@%@%@", @"some text", stringVariable, @"some more text"];

The escape code " can also be used instead of ".

Depends a lot on your definition of what a "character" is. If "rune equals a character " is OK for your task (generally it isn't) then the answer by VonC is perfect for you. Otherwise, it should be probably noted, that there are few situations where the number of runes in a Unicode string is an interesting value. And even in those situations it's better, if possible, to infer the count while "traversing" the string as the runes are processed to avoid doubling the UTF-8 decode effort.

Had the same issue with Ionic routing.

Simple solution is to use the name of the state - basically state.go(state name)

.state('tab.search', {
    url: '/search',
    views: {
      'tab-search': {
        templateUrl: 'templates/search.html',
        controller: 'SearchCtrl'
      }
    }
  })

And in controller you can use $state.go('tab.search');

Try This:

import os,shutil

def copydir(src, dst):
  h = os.getcwd()
  src = r"{}".format(src)
  if not os.path.isdir(dst):
     print("\n[!] No Such directory: ["+dst+"] !!!")
     exit(1)

  if not os.path.isdir(src):
     print("\n[!] No Such directory: ["+src+"] !!!")
     exit(1)
  if "\\" in src:
     c = "\\"
     tsrc = src.split("\\")[-1:][0]
  else:
    c = "/"
    tsrc = src.split("/")[-1:][0]

  os.chdir(dst)
  if os.path.isdir(tsrc):
    print("\n[!] The Directory Is already exists !!!")
    exit(1)
  try:
    os.mkdir(tsrc)
  except WindowsError:
    print("\n[!] Error: In[ {} ]\nPlease Check Your Dirctory Path !!!".format(src))
    exit(1)
  os.chdir(h)
  files = []
  for i in os.listdir(src):
    files.append(src+c+i)
  if len(files) > 0:
    for i in files:
        if not os.path.isdir(i):
            shutil.copy2(i, dst+c+tsrc)

  print("\n[*] Done ! :)")

copydir("c:\folder1", "c:\folder2")

You can just wrap the expression in a call to list:

>>> list(x for x in string.letters if x in (y for y in "BigMan on campus"))
['a', 'c', 'g', 'i', 'm', 'n', 'o', 'p', 's', 'u', 'B', 'M']

You declare

int countlines(char *filename)

to take a char * argument.

You call it like this

countlines(fp)

passing in a FILE *.

That is why you get that compile error.

You probably should change that second line to

countlines("Test.txt")

since you open the file in countlines

Your current code is attempting to open the file in two different places.

My answer

/**
 * Display form to reply comment
 */
function displayReplyForm(commentId) {
    var replyForm = $('#reply-form-' + commentId);
    if (replyForm.css('display') == 'block') { // Current display
        replyForm.css('display', 'none');
    } else { // Hide reply form
        replyForm.css('display', 'block');
    }
}

The fix is to ignore loop references and not to serialize them. This behaviour is specified in JsonSerializerSettings.

Single JsonConvert with an overload:

JsonConvert.SerializeObject((from a in db.Events where a.Active select a).ToList(), Formatting.Indented,
    new JsonSerializerSettings() {
        ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore
    }
);

If you'd like to make this the default behaviour, add a Global Setting with code in Application_Start() in Global.asax.cs:

JsonConvert.DefaultSettings = () => new JsonSerializerSettings {
     Formatting = Newtonsoft.Json.Formatting.Indented,
     ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore
};
