Programs & Examples On #Boundcolumn

Use listboxControl.Column(intColumn,intRow). Both Column and Row are zero-based.

You can use sum() with a generator expression here. The generator expression will be [1, 1, ...] up to the length of the file. Then we call sum() to add them all together, to get the total count.

with open('text.txt') as myfile:
    count = sum(1 for line in myfile)

It seems by what you have tried that you don't want to include empty lines. You can then do:

with open('text.txt') as myfile:
    count = sum(1 for line in myfile if line.rstrip('\n'))

I assume you are using TCP sockets for the client-server interaction? One way to send different types of data to the server and have it be able to differentiate between the two is to dedicate the first byte (or more if you have more than 256 types of messages) as some kind of identifier. If the first byte is one, then it is message A, if its 2, then its message B. One easy way to send this over the socket is to use DataOutputStream/DataInputStream:

Client:

Socket socket = ...; // Create and connect the socket
DataOutputStream dOut = new DataOutputStream(socket.getOutputStream());

// Send first message
dOut.writeByte(1);
dOut.writeUTF("This is the first type of message.");
dOut.flush(); // Send off the data

// Send the second message
dOut.writeByte(2);
dOut.writeUTF("This is the second type of message.");
dOut.flush(); // Send off the data

// Send the third message
dOut.writeByte(3);
dOut.writeUTF("This is the third type of message (Part 1).");
dOut.writeUTF("This is the third type of message (Part 2).");
dOut.flush(); // Send off the data

// Send the exit message
dOut.writeByte(-1);
dOut.flush();

dOut.close();

Server:

Socket socket = ... // Set up receive socket
DataInputStream dIn = new DataInputStream(socket.getInputStream());

boolean done = false;
while(!done) {
  byte messageType = dIn.readByte();

  switch(messageType)
  {
  case 1: // Type A
    System.out.println("Message A: " + dIn.readUTF());
    break;
  case 2: // Type B
    System.out.println("Message B: " + dIn.readUTF());
    break;
  case 3: // Type C
    System.out.println("Message C [1]: " + dIn.readUTF());
    System.out.println("Message C [2]: " + dIn.readUTF());
    break;
  default:
    done = true;
  }
}

dIn.close();

Obviously, you can send all kinds of data, not just bytes and strings (UTF).

Note that writeUTF writes a modified UTF-8 format, preceded by a length indicator of an unsigned two byte encoded integer giving you 2^16 - 1 = 65535 bytes to send. This makes it possible for readUTF to find the end of the encoded string. If you decide on your own record structure then you should make sure that the end and type of the record is either known or detectable.

Field.CurrentPage only works for Filter fields (also called page fields).
If you want to filter a row/column field, you have to cycle through the individual items, like so:

Sub FilterPivotField(Field As PivotField, Value)
    Application.ScreenUpdating = False
    With Field
        If .Orientation = xlPageField Then
            .CurrentPage = Value
        ElseIf .Orientation = xlRowField Or .Orientation = xlColumnField Then
            Dim i As Long
            On Error Resume Next ' Needed to avoid getting errors when manipulating PivotItems that were deleted from the data source.
            ' Set first item to Visible to avoid getting no visible items while working
            .PivotItems(1).Visible = True
            For i = 2 To Field.PivotItems.Count
                If .PivotItems(i).Name = Value Then _
                    .PivotItems(i).Visible = True Else _
                    .PivotItems(i).Visible = False
            Next i
            If .PivotItems(1).Name = Value Then _
                .PivotItems(1).Visible = True Else _
                .PivotItems(1).Visible = False
        End If
    End With
    Application.ScreenUpdating = True
End Sub

Then, you would just call:

FilterPivotField ActiveSheet.PivotTables("PivotTable2").PivotFields("SavedFamilyCode"), "K123223"

Naturally, this gets slower the more there are individual different items in the field. You can also use SourceName instead of Name if that suits your needs better.

This will work in Python 3

It's an interesting question, because it shows that there are a lot of different approaches to achieve the same result. Below I show three different implementations.

Default methods in Collection Framework: Java 8 added some methods to the collections classes, that are not directly related to the Stream API. Using these methods, you can significantly simplify the implementation of the non-stream implementation:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    Map<String, DataSet> result = new HashMap<>();
    multiDataPoints.forEach(pt ->
        pt.keyToData.forEach((key, value) ->
            result.computeIfAbsent(
                key, k -> new DataSet(k, new ArrayList<>()))
            .dataPoints.add(new DataPoint(pt.timestamp, value))));
    return result.values();
}

Stream API with flatten and intermediate data structure: The following implementation is almost identical to the solution provided by Stuart Marks. In contrast to his solution, the following implementation uses an anonymous inner class as intermediate data structure.

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.keyToData.entrySet().stream().map(e ->
            new Object() {
                String key = e.getKey();
                DataPoint dataPoint = new DataPoint(mdp.timestamp, e.getValue());
            }))
        .collect(
            collectingAndThen(
                groupingBy(t -> t.key, mapping(t -> t.dataPoint, toList())),
                m -> m.entrySet().stream().map(e -> new DataSet(e.getKey(), e.getValue())).collect(toList())));
}

Stream API with map merging: Instead of flattening the original data structures, you can also create a Map for each MultiDataPoint, and then merge all maps into a single map with a reduce operation. The code is a bit simpler than the above solution:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .map(mdp -> mdp.keyToData.entrySet().stream()
            .collect(toMap(e -> e.getKey(), e -> asList(new DataPoint(mdp.timestamp, e.getValue())))))
        .reduce(new HashMap<>(), mapMerger())
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

You can find an implementation of the map merger within the Collectors class. Unfortunately, it is a bit tricky to access it from the outside. Following is an alternative implementation of the map merger:

<K, V> BinaryOperator<Map<K, List<V>>> mapMerger() {
    return (lhs, rhs) -> {
        Map<K, List<V>> result = new HashMap<>();
        lhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        rhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        return result;
    };
}

$http is a promise too, you can make it simpler:

return $q.all(tasks.map(function(d){
        return $http.post('upload/tasks',d).then(someProcessCallback, onErrorCallback);
    }));

If you're using MacBook.

1. Set up node.js in your system and open up the terminal
2. Navigate to the directory, where the js file is saved.
3. To execute run node <filename.js>

example, if filename is script.js run node script.js

In 5.5 links() is replaced with render() which appears to work similarly. [Official DOC]

replace

{{ $replies->links() }}

with

{{ $replies->render("pagination::default") }}

Following commands will generate Pagination template in resources/views/vendor/pagination

artisan vendor:publish --tag=laravel-pagination
artisan vendor:publish

In any view file (blade files) you can use those template like following ex:

• {{ $replies->render("pagination::default") }}
• {{ $replies->render("pagination::bootstrap-4") }}
• {{ $replies->render("pagination::simple-bootstrap-4") }}
• {{ $replies->render("pagination::semantic-ui") }}

try this... it works for me.

double vdouble = 0;
string sparam = "2,1";

if ( !Double.TryParse( sparam, NumberStyles.Float, CultureInfo.InvariantCulture, out vdouble ) )
{
    if ( sparam.IndexOf( '.' ) != -1 )
    {
        sparam = sparam.Replace( '.', ',' );
    }
    else
    {
        sparam = sparam.Replace( ',', '.' );
    }

    if ( !Double.TryParse( sparam, NumberStyles.Float, CultureInfo.InvariantCulture, out vdouble ) )
    {
        vdouble = 0;
    }
}

There are a several ways of declaring variables in SQL*Plus scripts.

The first is to use VAR, to declare a bind variable. The mechanism for assigning values to a VAR is with an EXEC call:

SQL> var name varchar2(20)
SQL> exec :name := 'SALES'

PL/SQL procedure successfully completed.

SQL> select * from dept
  2  where dname = :name
  3  /

    DEPTNO DNAME          LOC
---------- -------------- -------------
        30 SALES          CHICAGO

SQL>

A VAR is particularly useful when we want to call a stored procedure which has OUT parameters or a function.

Alternatively we can use substitution variables. These are good for interactive mode:

SQL> accept p_dno prompt "Please enter Department number: " default 10
Please enter Department number: 20
SQL> select ename, sal
  2  from emp
  3  where deptno = &p_dno
  4  /
old   3: where deptno = &p_dno
new   3: where deptno = 20

ENAME             SAL
---------- ----------
CLARKE            800
ROBERTSON        2975
RIGBY            3000
KULASH           1100
GASPAROTTO       3000

SQL>

When we're writing a script which calls other scripts it can be useful to DEFine the variables upfront. This snippet runs without prompting me to enter a value:

SQL> def p_dno = 40
SQL> select ename, sal
  2  from emp
  3  where deptno = &p_dno
  4  /
old   3: where deptno = &p_dno
new   3: where deptno = 40

no rows selected

SQL>

Finally there's the anonymous PL/SQL block. As you see, we can still assign values to declared variables interactively:

SQL> set serveroutput on size unlimited
SQL> declare
  2      n pls_integer;
  3      l_sal number := 3500;
  4      l_dno number := &dno;
  5  begin
  6      select count(*)
  7      into n
  8      from emp
  9      where sal > l_sal
 10      and deptno = l_dno;
 11      dbms_output.put_line('top earners = '||to_char(n));
 12  end;
 13  /
Enter value for dno: 10
old   4:     l_dno number := &dno;
new   4:     l_dno number := 10;
top earners = 1

PL/SQL procedure successfully completed.

SQL>

Just do

onclick="SubmitFrm"

The javascript: prefix is only required for link URLs.

Your code (or some code called by you) is making a call to a COM method which is returning an unknown value. If you can find that then you're half way there.

You could try breaking when the exception is thrown. Go to Debug > Exceptions... and use the Find... option to locate System.Runtime.InteropServices.COMException. Tick the option to break when it's thrown and then debug your application.

Hopefully it will break somewhere meaningful and you'll be able to trace back and find the source of the error.

These Lines must be in OnCreate:

mmAdapter = new Adapter(msgList);
mrecyclerView.setAdapter(mmAdapter);

By writing below code you will get the location:

/storage/663D-554E/Android/data/app_package_name/files/

which stores your app data at /android/data location inside the sd_card.

File[] list = ContextCompat.getExternalFilesDirs(MainActivity.this, null);

list[1]+"/fol" 

for getting location pass 0 for internal and 1 for sdcard to file array.

I have tested this code on a moto g4 plus and Samsung device (all works fine).

hope this might helpful.

All other answers are useful but they may not help you in case nginx is not on PATH so you're getting command not found when trying to run nginx:

I have nginx 1.2.1 on Debian 7 Wheezy, the nginx executable is not on PATH, so I needed to locate it first. It was already running, so using ps aux | grep nginx I have found out that it's located on /usr/sbin/nginx, therefore I needed to run /usr/sbin/nginx -t.

If you want to use a non-default configuration file (i.e. not /etc/nginx/nginx.conf), run it with the -c parameter: /usr/sbin/nginx -c <path-to-configuration> -t.

You may also need to run it as root, otherwise nginx may not have permissions to open for example logs, so the command would fail.

def test():
    r1 = 1
    r2 = 2
    r3 = 3
    return r1, r2, r3

print z

Since this is a fatal error and also quite difficult to debug, maybe the fix could be put somewhere (in the provided command line?):

export GPG_TTY=$(tty)

From: https://github.com/keybase/keybase-issues/issues/2798

$( "#btn1" ).click(function() {
 $('#btn2').css('display','none');
});

You should check it against null.

If you want to check if object x is null or not, you can do:

    if(x != null)

But if it is not null, it can have properties which are null or empty. You will check those explicitly:

    if(x.getProperty() != null)

For "empty" check, it depends on what type is involved. For a Java String, you usually do:

    if(str != null && !str.isEmpty())

As you haven't mentioned about any specific problem with this, difficult to tell.

The steps in order to make a full check are:

Prepare the captor :

ArgumentCaptor<SomeArgumentClass> someArgumentCaptor = ArgumentCaptor.forClass(SomeArgumentClass.class);

verify the call to dependent on component (collaborator of subject under test). times(1) is the default value, so ne need to add it.

verify(dependentOnComponent, times(1)).send(someArgumentCaptor.capture());

Get the argument passed to collaborator

SomeArgumentClass someArgument = messageCaptor.getValue();

someArgument can be used for assertions

What if your lists contain duplicates like this:

v1 = ['s', 'h', 'e', 'e', 'p']
v2 = ['s', 's', 'h']

Sets do not contain duplicates. So, the following line returns True.

set(v2).issubset(v1)

To count for duplicates, you can use the code:

v1 = sorted(v1)
v2 = sorted(v2)


def is_subseq(v2, v1):
    """Check whether v2 is a subsequence of v1."""
    it = iter(v1)
    return all(c in it for c in v2) 

So, the following line returns False.

is_subseq(v2, v1)

Your http is being blocked by a firewall from F5 Networks called Application Security Manager (ASM). It produces messages like:

Please consult with your administrator.
Your support ID is: xxxxxxxxxxxx

So your application is passing some data that for some reason ASM detects as a threat. Give the support id to you network engineer to learn the specific reason.

My approach:

UINavigationBar.appearance().setBackgroundImage(
            UIImage(),
            forBarPosition: .Any,
            barMetrics: .Default)
    var _width:CGFloat! = self.navigationController?.navigationBar.layer.frame.width
            var _height:CGFloat! = self.navigationController?.navigationBar.layer.frame.height
            var navBarBg = UIView(frame:CGRectMake(0, 0, _width, _height))
            //solid color for bg
            navBarBg.backgroundColor = UIColor.orangeColor()
            view.addSubview(navBarBg)

Sounds like you're approaching your problem the wrong way to me.

Rewrite your code to use a tuple or write a class to store all of the data.

Sounds like you're looking to simulate the IE6 box model. You could use the CSS 3 property box-sizing: border-box to achieve this. This is supported by IE8, but for Firefox you would need to use -moz-box-sizing and for Safari/Chrome, use -webkit-box-sizing.

IE6 already computes the height wrong, so you're good in that browser, but I'm not sure about IE7, I think it will compute the height the same in quirks mode.

instead of the cookie variable you would just use document.cookie.split...

var cookie = 'cookie1=s; cookie1=; cookie2=test';_x000D_
var cookies = cookie.split('; ');_x000D_
cookies.forEach(function(c){_x000D_
  if(c.match(/cookie1=.+/))_x000D_
   console.log(true);_x000D_
});

In the HKEY_USERS\oneyouwanttoknow\ you can look at \Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders and it will reveal their profile paths. c:\users\whothisis\Desktop, etc.

You can specify become_method to override the default method set in ansible.cfg (if any), and which can be set to one of sudo, su, pbrun, pfexec, doas, dzdo, ksu.

- name: I am confused
  command: 'whoami'
  become: true
  become_method: su
  become_user: some_user
  register: myidentity

- name: my secret identity
  debug:
    msg: '{{ myidentity.stdout }}'

Should display

TASK [my-task : my secret identity] ************************************************************
ok: [my_ansible_server] => {
    "msg": "some_user"
}

In order to set CATALINA_HOME:

1. First, unzip and paste the apache-tomcat-7.1.100 folder in your C:// drive folder.

NOTE: Do not place your apache tomcat folder within any other folder or drive, place it directly in C:// drive folder only. (I did this mistake and none of the above-mentioned solutions were working).

2. Open environment variable dialog box (windows key+ pause-break key --> advanced setting).

3. Add a new variable name as "CATALINA_HOME" and add the variable path as "C://apache-tomcat-7.1.100"(as in my case), in System Variables.

4. Edit PATH variable name add "%CATALINA_HOME%\bin" and press OK.

5. Close the window and it will be saved.

6. Open Command Prompt window and type command- "%CATALINA_HOME%\bin\startup.bat" to run and start the Tomcat server.

7. END!

This will give a stack trace (as array of strings) for modern Chrome, Opera, Firefox and IE10+

function getStackTrace () {

  var stack;

  try {
    throw new Error('');
  }
  catch (error) {
    stack = error.stack || '';
  }

  stack = stack.split('\n').map(function (line) { return line.trim(); });
  return stack.splice(stack[0] == 'Error' ? 2 : 1);
}

Usage:

console.log(getStackTrace().join('\n'));

It excludes from the stack its own call as well as title "Error" that is used by Chrome and Firefox (but not IE).

It shouldn't crash on older browsers but just return empty array. If you need more universal solution look at stacktrace.js. Its list of supported browsers is really impressive but to my mind it is very big for that small task it is intended for: 37Kb of minified text including all dependencies.

JavaScript inserted as DOM text will not execute. However, you can use the dynamic script pattern to accomplish your goal. The basic idea is to move the script that you want to execute into an external file and create a script tag when you get your Ajax response. You then set the src attribute of your script tag and voila, it loads and executes the external script.

This other StackOverflow post may also be helpful to you: Can scripts be inserted with innerHTML?.

Now with Ruby 2.3 you can use &. operator ('lonely operator') to check for nil at the same time as accessing a value.

@person&.spouse&.name

https://en.wikibooks.org/wiki/Ruby_Programming/Syntax/Operators#Other_operators

Use #try instead so you don't have to keep checking for nil.

http://api.rubyonrails.org/classes/Object.html#method-i-try

@person.try(:spouse).try(:name)

instead of

@person.spouse.name if @person && @person.spouse

jQuery UI has a :data() selector which can also be used. It has been around since Version 1.7.0 it seems.

You can use it like this:

Get all elements with a data-company attribute

var companyElements = $("ul:data(group) li:data(company)");

Get all elements where data-company equals Microsoft

var microsoft = $("ul:data(group) li:data(company)")
                    .filter(function () {
                        return $(this).data("company") == "Microsoft";
                    });

Get all elements where data-company does not equal Microsoft

var notMicrosoft = $("ul:data(group) li:data(company)")
                       .filter(function () {
                           return $(this).data("company") != "Microsoft";
                       });

etc...

One caveat of the new :data() selector is that you must set the data value by code for it to be selected. This means that for the above to work, defining the data in HTML is not enough. You must first do this:

$("li").first().data("company", "Microsoft");

This is fine for single page applications where you are likely to use $(...).data("datakey", "value") in this or similar ways.

2017 Update - since WooCommerce 3:

global $product;
$id = $product->get_id();

Woocommerce doesn't like you accessing those variables directly. This will get rid of any warnings from woocommerce if your wp_debug is true.

Well, technically any such object will wind up being built over a C-style thread library because C++ only just specified a stock std::thread model in c++0x, which was just nailed down and hasn't yet been implemented. The problem is somewhat systemic, technically the existing c++ memory model isn't strict enough to allow for well defined semantics for all of the 'happens before' cases. Hans Boehm wrote an paper on the topic a while back and was instrumental in hammering out the c++0x standard on the topic.

http://www.hpl.hp.com/techreports/2004/HPL-2004-209.html

That said there are several cross-platform thread C++ libraries that work just fine in practice. Intel thread building blocks contains a tbb::thread object that closely approximates the c++0x standard and Boost has a boost::thread library that does the same.

http://www.threadingbuildingblocks.org/

http://www.boost.org/doc/libs/1_37_0/doc/html/thread.html

Using boost::thread you'd get something like:

#include <boost/thread.hpp>

void task1() { 
    // do stuff
}

void task2() { 
    // do stuff
}

I have an (ugly but effective) solution for this problem, which I used recently:

import java.lang.reflect.TypeVariable;


public static <T> Class<T> getGenericClass()
{
    __<T> ins = new __<T>();
    TypeVariable<?>[] cls = ins.getClass().getTypeParameters(); 

    return (Class<T>)cls[0].getClass();
}

private final class __<T> // generic helper class which does only provide type information
{
    private __()
    {
    }
}

You go into your router configuration and forward port 80 to the LAN IP of the computer running the web server.

Then anyone outside your network (but not you inside the network) can access your site using your WAN IP address (whatismyipcom).

I would rather use the Date valueOf method instead of === or !==

Seems like === is comparing internal Object's references and nothing concerning date.

Restart Netbeans & it solved my problem.

Global variables are not extern nor static by default on C and C++. When you declare a variable as static, you are restricting it to the current source file. If you declare it as extern, you are saying that the variable exists, but are defined somewhere else, and if you don't have it defined elsewhere (without the extern keyword) you will get a link error (symbol not found).

Your code will break when you have more source files including that header, on link time you will have multiple references to varGlobal. If you declare it as static, then it will work with multiple sources (I mean, it will compile and link), but each source will have its own varGlobal.

What you can do in C++, that you can't in C, is to declare the variable as const on the header, like this:

const int varGlobal = 7;

And include in multiple sources, without breaking things at link time. The idea is to replace the old C style #define for constants.

If you need a global variable visible on multiple sources and not const, declare it as extern on the header, and then define it, this time without the extern keyword, on a source file:

Header included by multiple files:

extern int varGlobal;

In one of your source files:

int varGlobal = 7;

If your working directory points to the trunk, then you should be able to merge your branch with:

svn merge https://HOST/repository/branches/branch_1

be sure to be to issue this command in the root directory of your trunk

Try this methode to redirect all to homepage new domain, Its works for me:

RewriteCond %{HTTP_HOST} ^olddomain\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.olddomain\.com$
RewriteRule ^(.*)$ "https\:\/\/newdomain\.com\/" [R=301,L]

You can simply compare it with System.DBNull.Value

Yes you can. You can even test it:

var i = 0;_x000D_
var timer = setInterval(function() {_x000D_
  console.log(++i);_x000D_
  if (i === 5) clearInterval(timer);_x000D_
  console.log('post-interval'); //this will still run after clearing_x000D_
}, 200);

In this example, this timer clears when i reaches 5.

Use sql from sql:

spool output of this to a file:

select 'alter index '||owner||'.'||index_name||' rebuild tablespace TO_TABLESPACE_NAME;' from all_indexes where owner='OWNERNAME';

spoolfile will have something like this:

alter index OWNER.PK_INDEX rebuild tablespace CORRECT_TS_NAME;

This question is old, but I'm surprised why no one mentioned boost::format:

cout << (boost::format("%x") % 1234).str();  // output is: 4d2

In IE you have to use attachEvent rather than the standard addEventListener.

A common practice is to check if the addEventListener method is available and use it, otherwise use attachEvent:

if (el.addEventListener){
  el.addEventListener('click', modifyText, false); 
} else if (el.attachEvent){
  el.attachEvent('onclick', modifyText);
}

You can make a function to do it:

function bindEvent(el, eventName, eventHandler) {
  if (el.addEventListener){
    el.addEventListener(eventName, eventHandler, false); 
  } else if (el.attachEvent){
    el.attachEvent('on'+eventName, eventHandler);
  }
}
// ...
bindEvent(document.getElementById('myElement'), 'click', function () {
  alert('element clicked');
});

You can run an example of the above code here.

The third argument of addEventListener is useCapture; if true, it indicates that the user wishes to initiate event capturing.

I had the same problem and wanted to change the product key to another. Unfortunate it's not as easy as it was on VS2010.

The following steps work:

• Remove the registry key containing the license information: HKEY_CLASSES_ROOT\Licenses\77550D6B-6352-4E77-9DA3-537419DF564B

• If you can't find the key, use sysinternals ProcessMonitor to check the registry access of VS2012 to locate the correct key which is always in HKEY_CLASSES_ROOT\Licenses

• After you remove this key, VS2012 will tell you that it's license information is incorrect. Go to "Programs and features" and repair VS2012.

• After the repair, VS2012 is reverted to a 30 day trial and you can enter a new product key. This could also be used to stay in a trial version loop and never enter a producy key.

The automatic install of peer dependencies was explicitly removed with npm 3, as it cause more problems than it tried to solve. You can read about it here for example:

• https://blog.npmjs.org/post/110924823920/npm-weekly-5
• https://github.com/npm/npm/releases/tag/v3.0.0

So no, for the reasons given, you cannot install them automatically with npm 3 upwards.

NPM V7

NPM v7 has reintroduced the automatic peerDependencies installation. They had made some changes to fix old problems as version compatibility across multiple dependants. You can see the discussion here and the announcement here

Now in V7, as in versions before V3, you only need to do an npm i and all peerDependences should be automatically installed.

Looks like the Google USB drivers have been updated to support Glass out of the box, so as long as you use the latest drivers, you should be able to access Glass via ADB. In my particular situation, I had connected Glass to my machine sometime mid-2014 but did nothing with it. Now when I was trying to connect it, I would not see it show up in ADB despite showing up in Device Manager. After much trial and error, I found out that I had to:

1. Go into Device Manager
2. Right click "Android ADB Interface" under "SAMSUNG Android Phone"
3. Click "Uninstall". BE SURE "Delete the driver software for this device" is checked.
4. Disconnect and reconnect Google Glass.

I was then able to reinstall the driver via regular Windows update. This forced it to look for the newest driver. Not sure why it was not getting updated before, but I hope this will help someone out there still struggling with this.

Just add \ at the end of line. For example

one\
two

Will become

one
two

It's also better than two spaces because it's visible.

I solved that problem.

I was implementing an OSI Layer (slider window, Level 2) for a network simulation in C++ (Eclipse Juno). I had frames (template <class T>) and its states (state pattern, forward declaration).

The solution is as follows:

In the *.cpp file, you must include the Header file that you forward, i.e.

ifndef STATE_H_
#define STATE_H_
#include <stdlib.h>
#include "Frame.h"

template <class T>
class LinkFrame;

using namespace std;

template <class T>
class State {

  protected:
    LinkFrame<int> *myFrame;

}

Its cpp:

#include "State.h"
#include "Frame.h"
#include  "LinkFrame.h"

template <class T>
bool State<T>::replace(Frame<T> *f){

And... another class.

Try not to use JDK versions higher than the ones supported. I've actually ran into a very ambiguous problem a few months ago.

I had a jar library of my own that I compiled with JDK 8, and I was using it in my assignment. It was giving me some kind of preDexDebug error every time I tried running it. Eventually after hours of trying to decipher the error logs I finally had an idea of what was wrong. I checked the system requirements, changed compilers from 8 to 7, and it worked. Looks like putting my jar into a library cost me a few hours rather than save it...

Here an example of how I do that, I don't know if it is the best solution, but works perfectly.

First, code in HTML. Look at ng-class, it's calling hasError function. Look also to the input's name declaration. I use the $index to create different input names.

<div data-ng-repeat="tipo in currentObject.Tipo"
    ng-class="{'has-error': hasError(planForm, 'TipoM', 'required', $index) || hasError(planForm, 'TipoM', 'maxlength', $index)}">
    <input ng-model="tipo.Nombre" maxlength="100" required
        name="{{'TipoM' + $index}}"/>

And now, here is the hasError function:

$scope.hasError = function (form, elementName, errorType, index) {
           if (form == undefined
               || elementName == undefined
               || errorType == undefined
               || index == undefined)
               return false;

           var element = form[elementName + index];
           return (element != null && element.$error[errorType] && element.$touched);
       };

I use the header(name, value) method and give the return to webResource var:

Client client = Client.create();
WebResource webResource = client.resource("uri");

MultivaluedMap<String, String> queryParams = new MultivaluedMapImpl();
queryParams.add("json", js); //set parametes for request

appKey = "Bearer " + appKey; // appKey is unique number

//Get response from RESTful Server get(ClientResponse.class);
ClientResponse response = webResource.queryParams(queryParams)
    .header("Content-Type", "application/json;charset=UTF-8")
    .header("Authorization", appKey)
    .get(ClientResponse.class);

String jsonStr = response.getEntity(String.class);

exit(0); // at the end of main function before closing curly braces

Yup, there's the convert_tz function.

For python version 3.7.3 in vscode with gitbash as the default terminal I was dealing with this for a while and then followed @Vitaliy Terziev advice of adding the alias to .bashrc but with the following specification:

alias python=’“/c/Users/my user name/AppData/Local/Programs/Python/Python37/python.exe”’

Notice the combination of single and double quotes because of “my user name” spaces.

For me, "winpty" couldn't resolve python path in vscode.

To center align an unordered list, you need to use the CSS text align property. In addition to this, you also need to put the unordered list inside the div element.

Now, add the style to the div class and use the text-align property with center as its value.

See the below example.

<style>
.myDivElement{
    text-align:center;
}
.myDivElement ul li{
   display:inline;

 }
</style>
<div class="myDivElement">
<ul>
    <li>Home</li>
    <li>About</li>
    <li>Gallery</li>
    <li>Contact</li>
</ul>
</div>

Here is the reference website Center Align Unordered List

Unless things have changed, you're better off with

public static ByteBuffer str_to_bb(String msg, Charset charset){
    return ByteBuffer.wrap(msg.getBytes(charset));
}

public static String bb_to_str(ByteBuffer buffer, Charset charset){
    byte[] bytes;
    if(buffer.hasArray()) {
        bytes = buffer.array();
    } else {
        bytes = new byte[buffer.remaining()];
        buffer.get(bytes);
    }
    return new String(bytes, charset);
}

Usually buffer.hasArray() will be either always true or always false depending on your use case. In practice, unless you really want it to work under any circumstances, it's safe to optimize away the branch you don't need.

Consider using the decorator pattern http://en.wikipedia.org/wiki/Decorator_pattern

You can change the decorator at runtime with one that has different properties when an event occurs.

You can use CustomMultiChildLayout to draw this kind of layouts. Here you can find a tutorial: How to Create Custom Layout Widgets in Flutter.

For me, in Python 3, it's working simply in this way:

keep = keep.union((0,1,2,3,4,5,6,7,8,9,10))

I don't know if it may be correct...

This for-loop will list all files in a directory.

pushd somedir
for /f "delims=" %%f in ('dir /b /a-d-h-s') do echo %%f
popd

"delims=" is useful to show long filenames with spaces in it....

'/b" show only names, not size dates etc..

Some things to know about dir's /a argument.

• Any use of "/a" would list everything, including hidden and system attributes.
• "/ad" would only show subdirectories, including hidden and system ones.
• "/a-d" argument eliminates content with 'D'irectory attribute.
• "/a-d-h-s" will show everything, but entries with 'D'irectory, 'H'idden 'S'ystem attribute.

If you use this on the commandline, remove a "%".

Hope this helps.

A rect can't contain a text element. Instead transform a g element with the location of text and rectangle, then append both the rectangle and the text to it:

var bar = chart.selectAll("g")
    .data(data)
  .enter().append("g")
    .attr("transform", function(d, i) { return "translate(0," + i * barHeight + ")"; });

bar.append("rect")
    .attr("width", x)
    .attr("height", barHeight - 1);

bar.append("text")
    .attr("x", function(d) { return x(d) - 3; })
    .attr("y", barHeight / 2)
    .attr("dy", ".35em")
    .text(function(d) { return d; });

Multi-line labels are also a little tricky, you might want to check out this wrap function.

I've been searching through all the examples and answers of how to pass any array to sql server without the hassle of creating new Table type,till i found this linK, below is how I applied it to my project:

--The following code is going to get an Array as Parameter and insert the values of that --array into another table

Create Procedure Proc1 


@UserId int, //just an Id param
@s nvarchar(max)  //this is the array your going to pass from C# code to your Sproc

AS

    declare @xml xml

    set @xml = N'<root><r>' + replace(@s,',','</r><r>') + '</r></root>'

    Insert into UserRole (UserID,RoleID)
    select 
       @UserId [UserId], t.value('.','varchar(max)') as [RoleId]


    from @xml.nodes('//root/r') as a(t)
END 

Hope you enjoy it

I had run a project clean, and installed or reinstalled everything and was still getting lots of Intellisense errors, even though my site was compiling and running fine. Intellisense finally worked for me when I changed the version numbers in my web.config file in the Views folder.

Here is a sample showing an easy way to do it. The script is:

$(function() {
  var _t = $("#container").scrollTop();
  $("#container").scroll(function() {
    var _n = $("#container").scrollTop();
    if (_n > _t) {
      $("#target").text("Down");
    } else {
      $("#target").text("Up");
    }
    _t = _n;
  });
});

The #container is your div id. The #target is just to see it working. Change to what you want when up or when down.

EDIT

The OP didn't say before, but since he's using a div with overflow: hidden, scrolling doesn't occur, then the script to detect the scroll is the least of it. Well, how to detect something that does not happen?!

So, the OP himself posted the link with what he wants, so why not use that library? http://cdn.jquerytools.org/1.2.5/full/jquery.tools.min.js.

The call is just:

$(function() {
    $(".scrollable").scrollable({ vertical: true, mousewheel: true });
});

I like for all objects that I'm binding to be defined in my ViewModel, so I try to avoid using <ObjectDataProvider> in the xaml when possible.

My solution uses no data defined in the View and no code-behind. Only a DataBinding, a reusable ValueConverter, a method to get a collection of descriptions for any Enum type, and a single property in the ViewModel to bind to.

When I want to bind an Enum to a ComboBox the text I want to display never matches the values of the Enum, so I use the [Description()] attribute to give it the text that I actually want to see in the ComboBox. If I had an enum of days of the week, it would look something like this:

public enum DayOfWeek
{
  // add an optional blank value for default/no selection
  [Description("")]
  NOT_SET = 0,
  [Description("Sunday")]
  SUNDAY,
  [Description("Monday")]
  MONDAY,
  ...
}

First I created helper class with a couple methods to deal with enums. One method gets a description for a specific value, the other method gets all values and their descriptions for a type.

public static class EnumHelper
{
  public static string Description(this Enum value)
  {
    var attributes = value.GetType().GetField(value.ToString()).GetCustomAttributes(typeof(DescriptionAttribute), false);
    if (attributes.Any())
      return (attributes.First() as DescriptionAttribute).Description;

    // If no description is found, the least we can do is replace underscores with spaces
    // You can add your own custom default formatting logic here
    TextInfo ti = CultureInfo.CurrentCulture.TextInfo;
    return ti.ToTitleCase(ti.ToLower(value.ToString().Replace("_", " ")));
  }

  public static IEnumerable<ValueDescription> GetAllValuesAndDescriptions(Type t)
  {
    if (!t.IsEnum)
      throw new ArgumentException($"{nameof(t)} must be an enum type");

    return Enum.GetValues(t).Cast<Enum>().Select((e) => new ValueDescription() { Value = e, Description = e.Description() }).ToList();
  }
}

Next, we create a ValueConverter. Inheriting from MarkupExtension makes it easier to use in XAML so we don't have to declare it as a resource.

[ValueConversion(typeof(Enum), typeof(IEnumerable<ValueDescription>))]
public class EnumToCollectionConverter : MarkupExtension, IValueConverter
{
  public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
  {
    return EnumHelper.GetAllValuesAndDescriptions(value.GetType());
  }
  public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
  {
    return null;
  }
  public override object ProvideValue(IServiceProvider serviceProvider)
  {
    return this;
  }
}

My ViewModel only needs 1 property that my View can bind to for both the SelectedValue and ItemsSource of the combobox:

private DayOfWeek dayOfWeek;

public DayOfWeek SelectedDay
{
  get { return dayOfWeek; }
  set
  {
    if (dayOfWeek != value)
    {
      dayOfWeek = value;
      OnPropertyChanged(nameof(SelectedDay));
    }
  }
}

And finally to bind the ComboBox view (using the ValueConverter in the ItemsSource binding)...

<ComboBox ItemsSource="{Binding Path=SelectedDay, Converter={x:EnumToCollectionConverter}, Mode=OneTime}"
          SelectedValuePath="Value"
          DisplayMemberPath="Description"
          SelectedValue="{Binding Path=SelectedDay}" />

To implement this solution you only need to copy my EnumHelper class and EnumToCollectionConverter class. They will work with any enums. Also, I didn't include it here, but the ValueDescription class is just a simple class with 2 public object properties, one called Value, one called Description. You can create that yourself or you can change the code to use a Tuple<object, object> or KeyValuePair<object, object>

The need is the possible desire for reproducible results, which may for example come from trying to debug your program, or of course from trying to redo what it does:

These two results we will "never" reproduce as I just asked for something "random":

R> sample(LETTERS, 5)
[1] "K" "N" "R" "Z" "G"
R> sample(LETTERS, 5)
[1] "L" "P" "J" "E" "D"

These two, however, are identical because I set the seed:

R> set.seed(42); sample(LETTERS, 5)
[1] "X" "Z" "G" "T" "O"
R> set.seed(42); sample(LETTERS, 5)
[1] "X" "Z" "G" "T" "O"
R> 

There is vast literature on all that; Wikipedia is a good start. In essence, these RNGs are called Pseudo Random Number Generators because they are in fact fully algorithmic: given the same seed, you get the same sequence. And that is a feature and not a bug.

Unused "private http: Http" argument in the constructor of app.component.ts had caused me the same error and it resolved upon removing the unused argument of the constructor

I know when you said "contents" you didn't mean this, but if you want to find all the values of all the attributes of a webelement this is a pretty nifty way to do that with javascript in python:

everything = b.execute_script(
    'var element = arguments[0];'
    'var attributes = {};'
    'for (index = 0; index < element.attributes.length; ++index) {'
    '    attributes[element.attributes[index].name] = element.attributes[index].value };'
    'var properties = [];'
    'properties[0] = attributes;'
    'var element_text = element.textContent;'
    'properties[1] = element_text;'
    'var styles = getComputedStyle(element);'
    'var computed_styles = {};'
    'for (index = 0; index < styles.length; ++index) {'
    '    var value_ = styles.getPropertyValue(styles[index]);'
    '    computed_styles[styles[index]] = value_ };'
    'properties[2] = computed_styles;'
    'return properties;', element)

you can also get some extra data with element.__dict__.

I think this is about all the data you'd ever want to get from a webelement.

Just use .text-center class if you're using Bootstrap 3.

<div class="text-center">
    <img src="..." alt="..."/>
</div>

Note: This doesn't work with img-responsive

This is Pythons way do show you unicode encoded strings. But i think you should be able to print the string on the screen or write it into a new file without any problems.

>>> test = u"I don\u2018t like this"
>>> test
u'I don\u2018t like this'
>>> print test
I don‘t like this

Assuming you use VS Express and C#. The icon is set in the project properties page. To open it right click on the project name in the solution explorer. in the page that opens, there is an Application tab, in this tab you can set the icon.

As of jQuery 1.6, you could (and some would say should) use .prop instead of .attr

$('.test').click(function(){
    alert($(this).prop('id'));
});

It is discussed further in this post: .prop() vs .attr()

Investigating this error on my new Win 7 laptop, I found my ADT plugin to be missing. By adding this I solved the problem: Downloading the ADT Plugin

Use the Update Manager feature of your Eclipse installation to install the latest revision of ADT on your development computer.

Assuming that you have a compatible version of the Eclipse IDE installed, as described in Preparing for Installation, above, follow these steps to download the ADT plugin and install it in your Eclipse environment.

Start Eclipse, then select Help > Install New Software.... Click Add, in the top-right corner. In the Add Repository dialog that appears, enter "ADT Plugin" for the Name and the following URL for the Location: https://dl-ssl.google.com/android/eclipse/ Click OK

Note: If you have trouble acquiring the plugin, try using "http" in the Location URL, instead of "https" (https is preferred for security reasons). In the Available Software dialog, select the checkbox next to Developer Tools and click Next. In the next window, you'll see a list of the tools to be downloaded. Click Next. Read and accept the license agreements, then click Finish.

Note: If you get a security warning saying that the authenticity or validity of the software can't be established, click OK. When the installation completes, restart Eclipse.

For Xampp version on Windows

Add this line to xampp\phpmyadmin\config.inc.php

$cfg['ExecTimeLimit'] = 6000;

And Change xampp\php\php.ini to

post_max_size = 750M 
upload_max_filesize = 750M   
max_execution_time = 5000
max_input_time = 5000
memory_limit = 1000M

And change xampp\mysql\bin\my.ini

max_allowed_packet = 200M

I had a similar problem (and VBScript or PowerShell was not an option) and the code I found in this article did not work for me. I had problems with OS versions and language versions. After some experiments I've come to this solution:

for /f "usebackq tokens=2,3*" %%A in (`REG QUERY "HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders" /v "Desktop"`) do if %%A==REG_EXPAND_SZ call :reparse set desktopdir=%%B
echo %desktopdir%
goto :EOF

:reparse
%*
goto :EOF

This code works for me in English and Polish versions of Windows 7 and Windows XP.

The :reparse subroutine allows for delayed expansion of environment variables.

The toggle tells Bootstrap what to do and the target tells Bootstrap which element is going to open. So whenever a link like that is clicked, a modal with an id of “basicModal” will appear.

Jon Skeet has written a library called morelinq which has a DistinctBy() operator. See here for the implementation. Your code would look like

IEnumerable<Note> distinctNotes = Notes.DistinctBy(note => note.Author);

Update: After re-reading your question, Kirk has the correct answer if you're just looking for a distinct set of Authors.

Added sample, several fields in DistinctBy:

res = res.DistinctBy(i => i.Name).DistinctBy(i => i.ProductId).ToList();

I arrived at this question looking for a way to stream an open ended list of objects onto a System.IO.Stream and read them off the other end, without buffering the entire list before sending. (Specifically I'm streaming persisted objects from MongoDB over Web API.)

@Paul Tyng and @Rivers did an excellent job answering the original question, and I used their answers to build a proof of concept for my problem. I decided to post my test console app here in case anyone else is facing the same issue.

Note that you may receive an exception when the AnonymousPipeServerStream is disposed, I ignored this as it isn't relevant to the problem at hand.

Try this. It's the easiest & most efficient way

<style name="datepicker" parent="Theme.AppCompat.Light.Dialog">

For what it's worth, it appears your intent is to use the incoming HTTP request to form another HTTP request. Sort of like a gateway. There is an excellent module django-revproxy that accomplishes exactly this.

The source is a pretty good reference on how to accomplish what you are trying to do.

If I start with a 3x4 array, and concatenate a 3x1 array, with axis 1, I get a 3x5 array:

In [911]: x = np.arange(12).reshape(3,4)
In [912]: np.concatenate([x,x[:,-1:]], axis=1)
Out[912]: 
array([[ 0,  1,  2,  3,  3],
       [ 4,  5,  6,  7,  7],
       [ 8,  9, 10, 11, 11]])
In [913]: x.shape,x[:,-1:].shape
Out[913]: ((3, 4), (3, 1))

Note that both inputs to concatenate have 2 dimensions.

Omit the :, and x[:,-1] is (3,) shape - it is 1d, and hence the error:

In [914]: np.concatenate([x,x[:,-1]], axis=1)
...
ValueError: all the input arrays must have same number of dimensions

The code for np.append is (in this case where axis is specified)

return concatenate((arr, values), axis=axis)

So with a slight change of syntax append works. Instead of a list it takes 2 arguments. It imitates the list append is syntax, but should not be confused with that list method.

In [916]: np.append(x, x[:,-1:], axis=1)
Out[916]: 
array([[ 0,  1,  2,  3,  3],
       [ 4,  5,  6,  7,  7],
       [ 8,  9, 10, 11, 11]])

np.hstack first makes sure all inputs are atleast_1d, and then does concatenate:

return np.concatenate([np.atleast_1d(a) for a in arrs], 1)

So it requires the same x[:,-1:] input. Essentially the same action.

np.column_stack also does a concatenate on axis 1. But first it passes 1d inputs through

array(arr, copy=False, subok=True, ndmin=2).T

This is a general way of turning that (3,) array into a (3,1) array.

In [922]: np.array(x[:,-1], copy=False, subok=True, ndmin=2).T
Out[922]: 
array([[ 3],
       [ 7],
       [11]])
In [923]: np.column_stack([x,x[:,-1]])
Out[923]: 
array([[ 0,  1,  2,  3,  3],
       [ 4,  5,  6,  7,  7],
       [ 8,  9, 10, 11, 11]])

All these 'stacks' can be convenient, but in the long run, it's important to understand dimensions and the base np.concatenate. Also know how to look up the code for functions like this. I use the ipython ?? magic a lot.

And in time tests, the np.concatenate is noticeably faster - with a small array like this the extra layers of function calls makes a big time difference.

If you want to change the backgorund image or color of the button when it is pressed, then just copy this code and paste in your project at exact location described below.

      <!-- Create new xml file like mybtn_layout.xml file in drawable -->
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="@drawable/pressed" /> <!--pressed --> 
<item android:drawable="@drawable/normal" /> <!-- Normal -->
</selector>
  <!-- Now this file should be in a drawable folder and use this 
  single line code in    button code to get all the properties of this xml file -->

    <Button
      android:id="@+id/street_btn"
      android:layout_width="wrap_content"
      android:background="@drawable/layout_a" > <!-- your required code -->
    </Button>

I don't think you can tell with the std::string class. However, if you really need this information, you could always derive a class from std::string and give the derived class the ability to tell if it had been changed since construction (or some other arbitrary time). Or better yet, just write a new class that wraps std::string since deriving from std::string may not be a good idea given the lack of a base class virtual destructor. That's probably more work, but more work tends to be needed for an optimal solution.

Of course, you can always just assume if it contains something other than "" then it has been "set", this won't detect it manually getting set to "" though.

if you need the batch file to schedule the backup, the SQL management tools have scheduled tasks built in...

With Visual Studio 2019, running a .net core 3.1 project, you will need to install the latest test framework to resolve the error.

Easiest way to accomplish this is by hovering the browser over a [Test] annotation (underlined in red) and select suggested fixes. The one needed is to "search for and install the latest test framework."

You are looking for a simple code, like this:

    List<string> tagList = new List<string>(new[]
    {
         "A"
        ,"B"
        ,"C"
        ,"D"
        ,"E"
    });

This is always fascinating. I am not a cloud developer, but based on my research there is nothing significantly different than what many of us have been doing off and on for decades. The server is platform specific. If you want to write platform agnostic code for your server that is fine, but unnecessary based on whoever your cloud server provider is. I think the biggest difference I've seen so far is the concept of providing a large set of services for the front end client to process. the front end, I'm assuming is predominantly web or web app development. As most browsers can handle LAMP vs Microsoft stack well enough, then you are still back to whatever your flavor of the month is. The only difference I truly am seeing from what I did 20 years ago in a highly distributed network environment are higher level protocol (HTTP vs. TCP/UDP). Maybe I am wrong and would welcome the education, but then again I've been doing this a long time and still have not seen anything I would consider revolutionary or significantly different, though languages like Java, C#, Python, Ruby, etc are significantly simpler to program in which is a mixed bag as the bar is lowered for those are are not familiar with writing optimized code. PAAS and SAAS to me seem to be some of the keys in the new technology, but been doing some of this to off and on for 20 years :)

PowerShell features a Restart-Service cmdlet, which either starts or restarts the service as appropriate.

The Restart-Service cmdlet sends a stop message and then a start message to the Windows Service Controller for a specified service. If a service was already stopped, it is started without notifying you of an error.

You can specify the services by their service names or display names, or you can use the InputObject parameter to pass an object that represents each service that you want to restart.

It is a little more foolproof than running two separate commands.

The easiest way to use it just pass either the service name or the display name directly:

Restart-Service 'Service Name'

It can be used directly from the standard cmd prompt with a command like:

powershell -command "Restart-Service 'Service Name'"

var example = "I am too long string";
var result;

// Slice is JS function
result = example.slice(0, 10)+'...'; //if you need dots after the string you can add

Result variable contains "I am too l..."

$("#closeLink").click(closeIt);

Let's say you want to call your function passing some args to it i.e., closeIt(1, false). Then, you should build an anonymous function and call closeIt from it.

$("#closeLink").click(function() {
    closeIt(1, false);
});

In case you're using a UITabBarController:

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    self.tabBarController?.navigationItem.hidesBackButton = true
}

Yes, this is a classpath issue. You need to tell the compiler and runtime that the directory where your .class files live is part of the CLASSPATH. The directory that you need to add is the parent of the "com" directory at the start of your package structure.

You do this using the -classpath argument for both javac.exe and java.exe.

Should also ask how the 3rd party classes you're using are packaged. If they're in a JAR, and I'd recommend that you have them in one, you add the .jar file to the classpath:

java -classpath .;company.jar foo.bar.baz.YourClass

Google for "Java classpath". It'll find links like this.

One more thing: "import" isn't loading classes. All it does it save you typing. When you include an import statement, you don't have to use the fully-resolved class name in your code - you can type "Foo" instead of "com.company.thing.Foo". That's all it's doing.

 private void CopyDataTable(DataTable table){
     // Create an object variable for the copy.
     DataTable copyDataTable;
     copyDataTable = table.Copy();
     // Insert code to work with the copy.
 }

On my machine:

C:\Program Files\PostgreSQL\8.4\data\postgresql.conf

Inspired by Nathanael Smith's answer and Eric Freese's comment, it could be as simple as:

var exec = require('child_process').exec;
exec('coffee -cw my_file.coffee').stdout.pipe(process.stdout);

You may want to use async/await, since node v10.0.0 it's possible with the built-in fs Promises API.

Example:

const fs = require('fs')

const copyFile = async (src, dest) => {
  await fs.promises.copyFile(src, dest)
}

Note:

As of node v11.14.0, v10.17.0 the API is no longer experimental.

The array module is kind of one of those things that you probably don't have a need for if you don't know why you would use it (and take note that I'm not trying to say that in a condescending manner!). Most of the time, the array module is used to interface with C code. To give you a more direct answer to your question about performance:

Arrays are more efficient than lists for some uses. If you need to allocate an array that you KNOW will not change, then arrays can be faster and use less memory. GvR has an optimization anecdote in which the array module comes out to be the winner (long read, but worth it).

On the other hand, part of the reason why lists eat up more memory than arrays is because python will allocate a few extra elements when all allocated elements get used. This means that appending items to lists is faster. So if you plan on adding items, a list is the way to go.

TL;DR I'd only use an array if you had an exceptional optimization need or you need to interface with C code (and can't use pyrex).

Don't get confused with too many explanations. DAO: From the name itself it means Accessing Data using Object. DAO is separated from other Business Logic.

Following code block shows how to calculate the difference in number of days between two dates using MomentJS.

var now = moment(new Date()); //todays date
var end = moment("2015-12-1"); // another date
var duration = moment.duration(now.diff(end));
var days = duration.asDays();
console.log(days)

you can use basename property

PS II> ls *.ps1 | select basename

Long count = (Long) session.createQuery("select count(*) from  Book").uniqueResult();

You can try something like this, if you use jQuery.

$("form").bind("keydown", function(e) {
   if (e.keyCode === 13) return false;
 });

That will wait for a keydown, if it is Enter, it will do nothing.

For me neither the @Rule nor the @RunWith(MockitoJUnitRunner.Silent.class) suggestions worked. It was a legacy project where we upgraded to mockito-core 2.23.0.

We could get rid of the UnnecessaryStubbingException by using:

Mockito.lenient().when(mockedService.getUserById(any())).thenReturn(new User());

instead of:

when(mockedService.getUserById(any())).thenReturn(new User());

Needless to say that you should rather look at the test code, but we needed to get the stuff compiled and the tests running first of all ;)

Try doing this :

awk '{print substr($0, 1, length($0)-1)}' file.txt

This is more generic than just removing the final comma but any last character

If you'd want to only remove the last comma with awk :

awk '{gsub(/,$/,""); print}' file.txt

I just found the solution, kind of answering to my own question in case anyone else stumbles upon it.

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,            "http://url/url/url" );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($ch, CURLOPT_POST,           1 );
curl_setopt($ch, CURLOPT_POSTFIELDS,     "body goes here" ); 
curl_setopt($ch, CURLOPT_HTTPHEADER,     array('Content-Type: text/plain')); 

$result=curl_exec ($ch);

I created this method to let use it not only on constructors but in methods:

My constructor:

function __construct() {
    $paramsNumber=func_num_args();
    if($paramsNumber==0){
        //do something
    }else{
        $this->overload('__construct',func_get_args());
    }
}

My doSomething method:

public function doSomething() {
    $paramsNumber=func_num_args();
    if($paramsNumber==0){
        //do something
    }else{
        $this->overload('doSomething',func_get_args());
    }
}

Both works with this simple method:

public function overloadMethod($methodName,$params){
    $paramsNumber=sizeof($params);
    //methodName1(), methodName2()...
    $methodNameNumber =$methodName.$paramsNumber;
    if (method_exists($this,$methodNameNumber)) {
        call_user_func_array(array($this,$methodNameNumber),$params);
    }
}

So you can declare

__construct1($arg1), __construct2($arg1,$arg2)...

or

methodName1($arg1), methodName2($arg1,$arg2)...

and so on :)

And when using:

$myObject =  new MyClass($arg1, $arg2,..., $argN);

it will call __constructN, where you defined N args

then $myObject -> doSomething($arg1, $arg2,..., $argM)

it will call doSomethingM, , where you defined M args;

You can also specify context location relatively to current classpath, which may be preferable

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:applicationContext*.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

Here's a updated version of ntoskrnl answer. It additionally contains a function to remove the final modifier like Arjan mentioned in the comments.

For starters:

<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.

This would be the optimal solution:

<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Best guess is you are on windows and your line ending settings are set for windows. See this topic: How to change line-ending settings

or use:

tr '\r\n' ' '

The order of execution of ng-click and ng-model is different with angular 1.2 vs 1.6

You must test, with 1.2 and 1.6,

for example, with angular 1.2, ng-click get execute before ng-model, with angular 1.6, ng-model maybe get excute before ng-click.

so you get 'true checked' / 'false uncheck' value maybe not you expect

java_home environment variable should point to the location of the proper version of java installation directory, so that tomcat starts with the right version. for example it you built the project with java 1.7 , then make sure that JAVA_HOME environment variable points to the jdk 1.7 installation directory in your machine.

I had same problem , when i deploy the war in tomcat and run, the link throws the error. But pointing the variable - JAVA_HOME to jdk 1.7 resolved the issue, as my war file was built in java 1.7 environment.

Let me throw out some example code that I got from http://www3.ntu.edu.sg/home/ehchua/programming/java/DateTimeCalendar.html Then you can play around with different options until you understand it.

import java.text.SimpleDateFormat;
import java.util.Date;

public class DateTest {
   public static void main(String[] args) {
       Date now = new Date();

       //This is just Date's toString method and doesn't involve SimpleDateFormat
       System.out.println("toString(): " + now);  // dow mon dd hh:mm:ss zzz yyyy
       //Shows  "Mon Oct 08 08:17:06 EDT 2012"

       SimpleDateFormat dateFormatter = new SimpleDateFormat("E, y-M-d 'at' h:m:s a z");
       System.out.println("Format 1:   " + dateFormatter.format(now));
       // Shows  "Mon, 2012-10-8 at 8:17:6 AM EDT"

       dateFormatter = new SimpleDateFormat("E yyyy.MM.dd 'at' hh:mm:ss a zzz");
       System.out.println("Format 2:   " + dateFormatter.format(now));
       // Shows  "Mon 2012.10.08 at 08:17:06 AM EDT"

       dateFormatter = new SimpleDateFormat("EEEE, MMMM d, yyyy");
       System.out.println("Format 3:   " + dateFormatter.format(now));
       // Shows  "Monday, October 8, 2012"

       // SimpleDateFormat can be used to control the date/time display format:
       //   E (day of week): 3E or fewer (in text xxx), >3E (in full text)
       //   M (month): M (in number), MM (in number with leading zero)
       //              3M: (in text xxx), >3M: (in full text full)
       //   h (hour): h, hh (with leading zero)
       //   m (minute)
       //   s (second)
       //   a (AM/PM)
       //   H (hour in 0 to 23)
       //   z (time zone)
       //  (there may be more listed under the API - I didn't check)

   }

}

Good luck!

This is what saved me. Apparently the depackager tries to put things in the wrong tmp folder.

The math.log function is to the base e, i.e. natural logarithm. If you want to the base 10 use math.log10.

This tutorial is very useful. To give a quick summary:

1. Use the CORS package available on Nuget: Install-Package Microsoft.AspNet.WebApi.Cors

2. In your WebApiConfig.cs file, add config.EnableCors() to the Register() method.

3. Add an attribute to the controllers you need to handle cors:

[EnableCors(origins: "<origin address in here>", headers: "*", methods: "*")]

You can save some homemade factorial functions on a separate module, utils.py, and then import them and compare the performance with the predefinite one, in scipy, numpy and math using timeit. In this case I used as external method the last proposed by Stefan Gruenwald:

import numpy as np


def factorial(n):
    return reduce((lambda x,y: x*y),range(1,n+1))

Main code (I used a framework proposed by JoshAdel in another post, look for how-can-i-get-an-array-of-alternating-values-in-python):

from timeit import Timer
from utils import factorial
import scipy

    n = 100

    # test the time for the factorial function obtained in different ways:

    if __name__ == '__main__':

        setupstr="""
    import scipy, numpy, math
    from utils import factorial
    n = 100
    """

        method1="""
    factorial(n)
    """

        method2="""
    scipy.math.factorial(n)  # same algo as numpy.math.factorial, math.factorial
    """

        nl = 1000
        t1 = Timer(method1, setupstr).timeit(nl)
        t2 = Timer(method2, setupstr).timeit(nl)

        print 'method1', t1
        print 'method2', t2

        print factorial(n)
        print scipy.math.factorial(n)

Which provides:

method1 0.0195569992065
method2 0.00638914108276

.offset() will return the offset position of an element as a simple object, eg:

var position = $(element).offset(); // position = { left: 42, top: 567 }

You can use this return value to position other elements at the same spot:

$(anotherElement).css(position)

Check to see if the key-value pair is actually showing up in the request:

In Chrome, found somewhere like: F12: Developer Tools > Network Tab > Whatever request you have sent > "view source" under Response Headers

Depending on your testing workflow, if whatever pair you added isn't there, you may just need to clear your browser cache. To verify that your browser is using your most up-to-date code, you can check the page's sources, in Chrome this is found somewhere like: F12: Developer Tools > Sources Tab > YourJavascriptSrc.js and check your code.

But as other answers have said:

xhttp.setRequestHeader(key, value);

should add a key-value pair to your request header, just make sure to place it after your open() and before your send()

I would explain that way:

OneToOne - OneToOne relationship

@OneToOne
Person person;

@OneToOne
Nose nose;

OneToMany - ManyToOne relationship

@OneToMany
Shepherd> shepherd;

@ManyToOne
List<Sheep> sheeps;

ManyToMany - ManyToMany relationship

@ManyToMany
List<Traveler> travelers;

@ManyToMany
List<Destination> destinations;

I ran into the exact same problem under identical circumstances. I don't have the tnsnames.ora file, and I wanted to use SQL*Plus with Easy Connection Identifier format in command line. I solved this problem as follows.

The SQL*Plus® User's Guide and Reference gives an example:

sqlplus hr@\"sales-server:1521/sales.us.acme.com\"

Pay attention to two important points:

1. The connection identifier is quoted. You have two options:
   1. You can use SQL*Plus CONNECT command and simply pass quoted string.
   2. If you want to specify connection parameters on the command line then you must add backslashes as shields before quotes. It instructs the bash to pass quotes into SQL*Plus.
2. The service name must be specified in FQDN-form as it configured by your DBA.

I found these good questions to detect service name via existing connection: 1, 2. Try this query for example:

SELECT value FROM V$SYSTEM_PARAMETER WHERE UPPER(name) = 'SERVICE_NAMES'

The best way to work around this is to specify the Dockerfile independently of the build context, using -f.

For instance, this command will give the ADD command access to anything in your current directory.

docker build -f docker-files/Dockerfile .

Update: Docker now allows having the Dockerfile outside the build context (fixed in 18.03.0-ce, https://github.com/docker/cli/pull/886). So you can also do something like

docker build -f ../Dockerfile .

A simple solution to this console.log problem is to define the following at the beginning of your JS code:

if (!window.console) window.console = {};
if (!window.console.log) window.console.log = function () { };

This works for me in all browsers. This creates a dummy function for console.log when the debugger is not active. When the debugger is active, the method console.log is defined and executes normally.

When working with bootsrap usually face three main problems:

1. How to place the content of the column to the bottom?
2. How to create a multi-row gallery of columns of equal height in one .row?
3. How to center columns horizontally if their total width is less than 12 and the remaining width is odd?

To solve first two problems download this small plugin https://github.com/codekipple/conformity

The third problem is solved here http://www.minimit.com/articles/solutions-tutorials/bootstrap-3-responsive-centered-columns

Common code

<style>
    [class*=col-] {position: relative}
    .row-conformity .to-bottom {position:absolute; bottom:0; left:0; right:0}
    .row-centered {text-align:center}   
    .row-centered [class*=col-] {display:inline-block; float:none; text-align:left; margin-right:-4px; vertical-align:top} 
</style>

<script src="assets/conformity/conformity.js"></script>
<script>
    $(document).ready(function () {
        $('.row-conformity > [class*=col-]').conformity();
        $(window).on('resize', function() {
            $('.row-conformity > [class*=col-]').conformity();
        });
    });
</script>

1. Aligning content of the column to the bottom

<div class="row row-conformity">
    <div class="col-sm-3">
        I<br>create<br>highest<br>column
    </div>
    <div class="col-sm-3">
        <div class="to-bottom">
            I am on the bottom
        </div>
    </div>
</div>

2. Gallery of columns of equal height

<div class="row row-conformity">
    <div class="col-sm-4">We all have equal height</div>
    <div class="col-sm-4">...</div>
    <div class="col-sm-4">...</div>
    <div class="col-sm-4">...</div>
    <div class="col-sm-4">...</div>
    <div class="col-sm-4">...</div>
</div>

3. Horizontal alignment of columns to the center (less than 12 col units)

<div class="row row-centered">
    <div class="col-sm-3">...</div>
    <div class="col-sm-4">...</div>
</div>

All classes can work together

<div class="row row-conformity row-centered">
    ...
</div>

In kotlin, we can solve this by creating a custom widget inheriting the ViewPager class and adding a flag value for controlling swipe behavior.

NoSwipePager.kt

class NoSwipePager(context: Context, attrs: AttributeSet) : ViewPager(context, attrs) {

    var pagingEnabled: Boolean = false

    override fun onTouchEvent(event: MotionEvent): Boolean {
        return if (this.pagingEnabled) {
            super.onTouchEvent(event)
        } else false
    }

    override fun onInterceptTouchEvent(event: MotionEvent): Boolean {
        return if (this.pagingEnabled) {
            super.onInterceptTouchEvent(event)
        } else false
    }
}

In xml

<your.package.NoSwipePager
    android:id="@+id/view_pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@id/tab_layout" />

Disable swiping programmatically. If kotlin-android-extensions plugin is applied in build.gradle, swiping can be disabled by writing below code.

view_pager.pagingEnabled = false

Otherwise we can disable swiping using code below:

val viewPager : ViewPager = findViewById(R.id.view_pager)
viewPager.pagingEnabled = false

It is important to clearly differentiate the idea behind using factory or factory method. Both are meant to address mutually exclusive different kind of object creation problems.

Let's be specific about "factory method":

First thing is that, when you are developing library or APIs which in turn will be used for further application development, then factory method is one of the best selections for creation pattern. Reason behind; We know that when to create an object of required functionality(s) but type of object will remain undecided or it will be decided ob dynamic parameters being passed.

Now the point is, approximately same can be achieved by using factory pattern itself but one huge drawback will introduce into the system if factory pattern will be used for above highlighted problem, it is that your logic of crating different objects(sub classes objects) will be specific to some business condition so in future when you need to extend your library's functionality for other platforms(In more technically, you need to add more sub classes of basic interface or abstract class so factory will return those objects also in addition to existing one based on some dynamic parameters) then every time you need to change(extend) the logic of factory class which will be costly operation and not good from design perspective. On the other side, if "factory method" pattern will be used to perform the same thing then you just need to create additional functionality(sub classes) and get it registered dynamically by injection which doesn't require changes in your base code.

interface Deliverable 
{
    /*********/
}

abstract class DefaultProducer 
{

    public void taskToBeDone() 
    {   
        Deliverable deliverable = factoryMethodPattern();
    }
    protected abstract Deliverable factoryMethodPattern();
}

class SpecificDeliverable implements Deliverable 
{
 /***SPECIFIC TASK CAN BE WRITTEN HERE***/
}

class SpecificProducer extends DefaultProducer 
{
    protected Deliverable factoryMethodPattern() 
    {
        return new SpecificDeliverable();
    }
}

public class MasterApplicationProgram 
{
    public static void main(String arg[]) 
    {
        DefaultProducer defaultProducer = new SpecificProducer();
        defaultProducer.taskToBeDone();
    }
}

Or you could use the known solution to this problem and use SSL. Self-signed certs are free and its a personal project right?

For files in a directory, you can use things like:

if exist *.csv echo "csv file found"

or

if not exist *.csv goto nofile

I faced the very same error when I was trying to connect to my SQL Server 2014 instance using sa user using SQL Server Management Studio (SSMS). I was facing this error even when security settings for sa user was all good and SQL authentication mode was enabled on the SQL Server instance.

Finally, the issue turned out to be that Named Pipes protocol was disabled. Here is how you can enable it:

Open SQL Server Configuration Manager application from start menu. Now, enable Named Pipes protocol for both Client Protocols and Protocols for <SQL Server Instance Name> nodes as shown in the snapshot below:

Note: Make sure you restart the SQL Server instance after making changes.

P.S. I'm not very sure but there is a possibility that the Named Pipes enabling was required under only one of the two nodes that I've advised. So you can try it one after the other to reach to a more precise solution.

First of all, IQueryable<T> extends the IEnumerable<T> interface, so anything you can do with a "plain" IEnumerable<T>, you can also do with an IQueryable<T>.

IEnumerable<T> just has a GetEnumerator() method that returns an Enumerator<T> for which you can call its MoveNext() method to iterate through a sequence of T.

What IQueryable<T> has that IEnumerable<T> doesn't are two properties in particular—one that points to a query provider (e.g., a LINQ to SQL provider) and another one pointing to a query expression representing the IQueryable<T> object as a runtime-traversable abstract syntax tree that can be understood by the given query provider (for the most part, you can't give a LINQ to SQL expression to a LINQ to Entities provider without an exception being thrown).

The expression can simply be a constant expression of the object itself or a more complex tree of a composed set of query operators and operands. The query provider's IQueryProvider.Execute() or IQueryProvider.CreateQuery() methods are called with an Expression passed to it, and then either a query result or another IQueryable is returned, respectively.

You can limit the scope of a playbook by changing the hosts header in its plays without relying on your special host label ‘local’ in your inventory. Localhost does not need a special line in inventories.

- name: run on all except local
  hosts: all:!local

You can multiply numpy arrays by scalars and it just works.

>>> import numpy as np
>>> np.array([1, 2, 3]) * 2
array([2, 4, 6])
>>> np.array([[1, 2, 3], [4, 5, 6]]) * 2
array([[ 2,  4,  6],
       [ 8, 10, 12]])

This is also a very fast and efficient operation. With your example:

>>> a_1 = np.array([1.0, 2.0, 3.0])
>>> a_2 = np.array([[1., 2.], [3., 4.]])
>>> b = 2.0
>>> a_1 * b
array([2., 4., 6.])
>>> a_2 * b
array([[2., 4.],
       [6., 8.]])

To test without copy elision and see you copy/move constructors/operators in action add "-fno-elide-constructors".

Even with no optimizations (-O0 ), GCC and Clang will still do copy elision, which has the effect of skipping copy/move constructors in some cases. See this question for the details about copy elision.

However, in Clang 3.4 it does trigger a bug (an invalid temporary object without calling constructor), which is fixed in 3.5.

I sometimes use NULLIF like so...

IF NULLIF(@PreviousStartDate, '') IS NULL

There's probably no reason it's better than the way suggested by @Oded and @bluefeet, just stylistic preference.

@danihp's method is really cool but my tired old brain wouldn't go to COALESCE when I'm thinking is null or empty :-)

You could use a Common Table Expression to create the SUM first, join it to the table, and then use the WHEN to to get the value from the CTE or the original table as necessary.

WITH PercentageOfTotal (Id, Percentage) 
AS 
(
    SELECT Id, (cnt / SUM(AreaId)) FROM dbo.MyTable GROUP BY Id
)
SELECT 
    CASE
        WHEN o.TotalType = 'Average' THEN r.avgscore
        WHEN o.TotalType = 'PercentOfTot' THEN pt.Percentage
        ELSE o.cnt
    END AS [displayscore]
FROM PercentageOfTotal pt
    JOIN dbo.MyTable t ON pt.Id = t.Id

Simple solution for cast pointer to object

Your System is not able to detect the path node js binary.

1.which node

2.Then soft link node to nodejs

ln -s [the path of nodejs] /usr/bin/node 

I am assuming /usr/bin is in your execution path. Then you can test by typing node or npm into your command line, and everything should work now.

Actually is quite easy with this option at the end:

c:\start BATCH.bat -WindowStyle Hidden

This is very easy step to import any 3rd party lib or jar file into your project

1. Copy android-support-v4.jar file from your_drive\android-sdks\extras\android\support\v4\android-support-v4.jar
   or copy from your existing project's bin folder.
   or any third party .jar file

2. paste copied jar file into lib folder

3. right click on this jar file and then click on build Path->Add to Build Path

4. even still you are getting error in your project then Clean the Project and Build it.

I would make a new image of the dog's silhouette (black) and the rest the same as the original image. In the html, add a wrapper div with this silhouette as as background. Now, make the original image semi-transparent. The dog will become darker and the background of the dog will stay the same. You can do :hover tricks by setting the opacity of the original image to 100% on hover. Then the dog pops out when you mouse over him!

style

.wrapper{background-image:url(silhouette.png);} 
.original{opacity:0.7:}
.original:hover{opacity:1}

<div class="wrapper">
  <div class="img">
    <img src="original.png">
  </div>
</div>

I agree with somebody's recently deleted post that the differences in performance are so small that, with very very few exceptions, (he got dinged for saying never) you should not make your design decision based upon that.

In your example, where the elements are Objects, the performance difference should be minimal.

If you are dealing with a large number of primitives, an array will offer significantly better performance, both in memory and time.

[matrix[i][column] for i in range(len(matrix))]

Use this to set Marque:

    final TextView tx = (TextView) findViewById(R.id.textView1);
    tx.setEllipsize(TruncateAt.MARQUEE);
    tx.setSelected(true);
    tx.setSingleLine(true);
    tx.setText("Marquee needs only three things to make it run and these three things are mentioned above.");

You do not need to use "android:marqueeRepeatLimit="marquee_forever" into xml file. Marquee will work even without this.

You could also use custom events:

function Typer() {
    // Some stuff

    $(anyDomElement).trigger("myCustomEvent");
}


$(anyDomElement).on("myCustomEvent", function() {
    // Some other stuff
});

If you just want to round the number for output purposes, then the "%.2f" format string is indeed the correct answer. However, if you actually want to round the floating point value for further computation, something like the following works:

#include <math.h>

float val = 37.777779;

float rounded_down = floorf(val * 100) / 100;   /* Result: 37.77 */
float nearest = roundf(val * 100) / 100;  /* Result: 37.78 */
float rounded_up = ceilf(val * 100) / 100;      /* Result: 37.78 */

Notice that there are three different rounding rules you might want to choose: round down (ie, truncate after two decimal places), rounded to nearest, and round up. Usually, you want round to nearest.

As several others have pointed out, due to the quirks of floating point representation, these rounded values may not be exactly the "obvious" decimal values, but they will be very very close.

For much (much!) more information on rounding, and especially on tie-breaking rules for rounding to nearest, see the Wikipedia article on Rounding.

You have to give the second argument of class type. You can also have it a little bit more tidy like below.

startActivity(Intent(this, Page2::class.java).apply {
    putExtra("extra_1", value1)
    putExtra("extra_2", value2)
    putExtra("extra_3", value3)
})

At the bottom, I have a general solution to replace lines in a file. But first, here is the answer to the specific question at hand. Helper function:

public static void replaceSelected(String replaceWith, String type) {
    try {
        // input the file content to the StringBuffer "input"
        BufferedReader file = new BufferedReader(new FileReader("notes.txt"));
        StringBuffer inputBuffer = new StringBuffer();
        String line;

        while ((line = file.readLine()) != null) {
            inputBuffer.append(line);
            inputBuffer.append('\n');
        }
        file.close();
        String inputStr = inputBuffer.toString();

        System.out.println(inputStr); // display the original file for debugging

        // logic to replace lines in the string (could use regex here to be generic)
        if (type.equals("0")) {
            inputStr = inputStr.replace(replaceWith + "1", replaceWith + "0"); 
        } else if (type.equals("1")) {
            inputStr = inputStr.replace(replaceWith + "0", replaceWith + "1");
        }

        // display the new file for debugging
        System.out.println("----------------------------------\n" + inputStr);

        // write the new string with the replaced line OVER the same file
        FileOutputStream fileOut = new FileOutputStream("notes.txt");
        fileOut.write(inputStr.getBytes());
        fileOut.close();

    } catch (Exception e) {
        System.out.println("Problem reading file.");
    }
}

Then call it:

public static void main(String[] args) {
    replaceSelected("Do the dishes", "1");   
}

Original Text File Content:

Do the dishes0
Feed the dog0
Cleaned my room1

Output:

Do the dishes0
Feed the dog0
Cleaned my room1
----------------------------------
Do the dishes1
Feed the dog0
Cleaned my room1

New text file content:

Do the dishes1
Feed the dog0
Cleaned my room1

And as a note, if the text file was:

Do the dishes1
Feed the dog0
Cleaned my room1

and you used the method replaceSelected("Do the dishes", "1");, it would just not change the file.

Since this question is pretty specific, I'll add a more general solution here for future readers (based on the title).

// read file one line at a time
// replace line as you read the file and store updated lines in StringBuffer
// overwrite the file with the new lines
public static void replaceLines() {
    try {
        // input the (modified) file content to the StringBuffer "input"
        BufferedReader file = new BufferedReader(new FileReader("notes.txt"));
        StringBuffer inputBuffer = new StringBuffer();
        String line;

        while ((line = file.readLine()) != null) {
            line = ... // replace the line here
            inputBuffer.append(line);
            inputBuffer.append('\n');
        }
        file.close();

        // write the new string with the replaced line OVER the same file
        FileOutputStream fileOut = new FileOutputStream("notes.txt");

Yes, MySQL has a REPLACE() function:

mysql> SELECT REPLACE('www.mysql.com', 'w', 'Ww');
    -> 'WwWwWw.mysql.com'

http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_replace

Note that it's easier if you make that an alias when using SELECT

SELECT REPLACE(string_column, 'search', 'replace') as url....

What solves my problem: I am using 64 bit Windows 7, so I thought I could install 64 bit Wamp. After I Installed the 32-bit version the error does not appear. So something in the developing process at Wamp went wrong...

[class*="test"],[class="second"] {
background: #ffff00;
}

public static final long SECOND_IN_MILLIS = 1000;
public static final long MINUTE_IN_MILLIS = SECOND_IN_MILLIS * 60;
public static final long HOUR_IN_MILLIS = MINUTE_IN_MILLIS * 60;
public static final long DAY_IN_MILLIS = HOUR_IN_MILLIS * 24;
public static final long WEEK_IN_MILLIS = DAY_IN_MILLIS * 7;

You could cast int but I would recommend using long.

I had similar problem. My file with sql script was over 150MB of size (with almost 900k of very simple INSERTs). I used solution advised by Takuro (as the answer in this question) but I still got error with message saying that there was not enough memory ("There is insufficient system memory in resource pool 'internal' to run this query").

What helped me was that I put GO command after every 50k INSERTs.

(It's not directly addressing the question (file size) but I believe it resolves problem that is indirectly connected with large size of sql script itself. In my case many insert commands)

str.replace(/[[\]]/g,'')

In onCreate with activity or in onCreateView with fragment.

 if (view != null) {
    ViewGroup parent = (ViewGroup) view.getParent();
    if (parent != null) {
        parent.removeView(view);
    }
}
try {
    view = inflater.inflate(R.layout.fragment_main, container, false);
} catch (InflateException e) {

}

$result = mysql_query("INSERT INTO PEOPLE (NAME ) VALUES ('COLE')"));
if($result)
{
echo "Success";

}
else
{
echo "Error";

}

The reason why your current approach doesn't work is because Jackson is used by default to serialize and to deserialize objects. However, it doesn't know how to serialize the JSONObject. If you want to create a dynamic JSON structure, you can use a Map, for example:

@GetMapping
public Map<String, String> sayHello() {
    HashMap<String, String> map = new HashMap<>();
    map.put("key", "value");
    map.put("foo", "bar");
    map.put("aa", "bb");
    return map;
}

This will lead to the following JSON response:

{ "key": "value", "foo": "bar", "aa": "bb" }

This is a bit limited, since it may become a bit more difficult to add child objects. Jackson has its own mechanism though, using ObjectNode and ArrayNode. To use it, you have to autowire ObjectMapper in your service/controller. Then you can use:

@GetMapping
public ObjectNode sayHello() {
    ObjectNode objectNode = mapper.createObjectNode();
    objectNode.put("key", "value");
    objectNode.put("foo", "bar");
    objectNode.put("number", 42);
    return objectNode;
}

This approach allows you to add child objects, arrays, and use all various types.

MacOS High Sierra is very crazy to update openssl command suddenly.

Possible in last month:

$ openssl pkcs12 -in cert.p12 -out cert.pem -nodes -clcerts
MAC verified OK

But now:

$ openssl pkcs12 -in cert.p12 -out cert.pem -nodes -clcerts -password pass:
MAC verified OK

Follow this, it can be like what you are looking:

var obj = {_x000D_
    Objone: 'one',_x000D_
    Objtwo: 'two'_x000D_
};_x000D_
_x000D_
var key = "Objone";_x000D_
delete obj[key];_x000D_
console.log(obj); // prints { "objtwo": two}

The following two cases relate to loading a properties file from an example class named TestLoadProperties.

Case 1: Loading the properties file using ClassLoader

InputStream inputStream = TestLoadProperties.class.getClassLoader()
                          .getResourceAsStream("A.config");
properties.load(inputStream);

In this case the properties file must be in the root/src directory for successful loading.

Case 2: Loading the properties file without using ClassLoader

InputStream inputStream = getClass().getResourceAsStream("A.config");
properties.load(inputStream);

In this case the properties file must be in the same directory as the TestLoadProperties.class file for successful loading.

Note: TestLoadProperties.java and TestLoadProperties.class are two different files. The former, .java file, is usually found in a project's src/ directory, while the latter, .class file, is usually found in its bin/ directory.

If you are looking for a direct approach and using a local File in that case. Try

<div
style={{ background-image: 'url(' + Image + ')', background-size: 'auto' }}
/>

This is the case of JS with inline styling where Image is a local file that you must have imported with a path.

If you are talking about the current transaction nesting level, then you would use @@TRANCOUNT.

If you are talking about transaction isolation level, use DBCC USEROPTIONS and look for an option of isolation level. If it isn't set, it's read committed.

An utility method like the following can be used to solve this.

import (
  "os"
  "path/filepath"
  "log"
)

func ensureDir(fileName string) {
  dirName := filepath.Dir(fileName)
  if _, serr := os.Stat(dirName); serr != nil {
    merr := os.MkdirAll(dirName, os.ModePerm)
    if merr != nil {
        panic(merr)
    }
  }
}



func main() {
  _, cerr := os.Create("a/b/c/d.txt")
  if cerr != nil {
    log.Fatal("error creating a/b/c", cerr)
  }
  log.Println("created file in a sub-directory.")
}

In bash:

$ convert -version

or

$ /usr/local/bin/convert -version

No need to write any PHP file just to check.

Very late to the game, but this is a version of Chris Pratt's answer that protects against race conditions while sacrificing performance, by using a transaction block and select_for_update()

@receiver(pre_save, sender=MyModel)
@transaction.atomic
def do_something_if_changed(sender, instance, **kwargs):
    try:
        obj = sender.objects.select_for_update().get(pk=instance.pk)
    except sender.DoesNotExist:
        pass # Object is new, so field hasn't technically changed, but you may want to do something else here.
    else:
        if not obj.some_field == instance.some_field: # Field has changed
            # do something

Here's an alternative that doesn't require regex:

var str = 'a b c';
var replaced = str.split(' ').join('+');

Try this plugin JQuery UI Message box. He uses jQuery UI Dialog.

I rise to the challenge of providing the signed answer:

def f(x,y):
  import math
  return min(y-x, y-x+2*math.pi, y-x-2*math.pi, key=abs)

[[ $list =~ (^|[[:space:]])$x($|[[:space:]]) ]] && echo 'yes' || echo 'no'

or create a function:

contains() {
    [[ $1 =~ (^|[[:space:]])$2($|[[:space:]]) ]] && exit(0) || exit(1)
}

to use it:

contains aList anItem
echo $? # 0: match, 1: failed

If you're using SQL Server Management Studio, you don't have to type the column list yourself - just right-click the table in Object Explorer and choose Script Table as -> SELECT to -> New Query Editor Window.

If you aren't, then a query similar to this should help as a starting point:

SELECT SUBSTRING(
    (SELECT ', ' + QUOTENAME(COLUMN_NAME)
        FROM INFORMATION_SCHEMA.COLUMNS
        WHERE TABLE_NAME = 'tbl_A'
        ORDER BY ORDINAL_POSITION
        FOR XML path('')),
    3,
    200000);

The way I solved it is by setting the AVD memory limit and HAXM memory to be equal in size which is 1 GB = 1024 MB. The AVD cannot have higher memory limit than the HAXM.

1. Setting the HAXM memory to be 1024 M

The only way to change the HAXM memory is by installing it again. I did it using the terminal. Locate Hardware_Accelerated_Execution_Manager in your machine. Then change directory that folder to run the installation script.

cd ~/Library/Android/sdk/extras/intel/Hardware_Accelerated_Execution_Manager

-OR-

cd ~/Library/Developer/Xamarin/android-sdk-macosx/extras/intel/Hardware_Accelerated_Execution_Manager

May need to change permissions:

sudo chmod 755 "HAXM installation"

Then:

./HAXM\ installation -m 1024

-OR-

sudo ./"HAXM installation" -m 1024

2. Setting the virtual device the same size with HAXM memory limit

This works for me. Good luck!

How about this for instance :

var youtubeimgsrc = document.getElementById("youtubeimg").getAttribute('src');

Make sure that git is installed on your system. I'm explaining the process using windows OS

Here is how I did :

1.Open the cmd (you can do with git bash as well).

2.Go to your project directory(where your project is located).

3.Now type your_directory >git init this will initialize an empty repository if it is first time and enter. for eg :C:\Users>git init

4.Now type your_directory >git add <filename>(if specific files) or git add . (if you want to add all files) and enter.

5.Now type >git commit -m "commit message goes here" and enter.

(in case if you need to check the status you can do by typing >git status) and enter.

6.Now type >git remote add origin git_repository_url

(check>git remote -v) and enter.

7.Now turn to push it ...>git push origin master and enter

(if you get error you push it forcefully by typing ...>git push -f origin master and enter.

Now you're done with adding it to your repository. Refresh it and it will be there in your created repository.

Hopefully, this will work for you.

You could use a custom button which measures and draws itself to accomodate a left drawable. Please find example and usage here

public class DrawableAlignedButton extends Button {

    public DrawableAlignedButton(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public DrawableAlignedButton(Context context) {
    super(context);
}

public DrawableAlignedButton(Context context, AttributeSet attrs, int style) {
    super(context, attrs, style);
}

private Drawable mLeftDrawable;

@Override
    //Overriden to work only with a left drawable.
public void setCompoundDrawablesWithIntrinsicBounds(Drawable left,
        Drawable top, Drawable right, Drawable bottom) {
    if(left == null) return;
    left.setBounds(0, 0, left.getIntrinsicWidth(), left.getIntrinsicHeight());
    mLeftDrawable = left;
}

@Override
protected void onDraw(Canvas canvas) {
    //transform the canvas so we can draw both image and text at center.
    canvas.save();
    canvas.translate(2+mLeftDrawable.getIntrinsicWidth()/2, 0);
    super.onDraw(canvas);
    canvas.restore();
    canvas.save();
    int widthOfText = (int)getPaint().measureText(getText().toString());
    int left = (getWidth()+widthOfText)/2 - mLeftDrawable.getIntrinsicWidth() - 2;
    canvas.translate(left, (getHeight()-mLeftDrawable.getIntrinsicHeight())/2);
    mLeftDrawable.draw(canvas);
    canvas.restore();
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    int height = getMeasuredHeight();
    height = Math.max(height, mLeftDrawable.getIntrinsicHeight() + getPaddingTop() + getPaddingBottom());
    setMeasuredDimension(getMeasuredWidth(), height);
}
}

Usage

<com.mypackage.DrawableAlignedButton
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:drawableLeft="@drawable/my_drawable"
        android:gravity="center"

What you probably want is for...of, a relatively new construct built for the express purpose of enumerating the values of iterable objects:

let myArray = ["a","b","c","d"];_x000D_
for (let item of myArray) {_x000D_
  console.log(item);_x000D_
}

... as distinct from for...in, which enumerates property names (presumably¹ numeric indices in the case of arrays). Your loop displayed unexpected results because you didn't use the property names to get the corresponding values via bracket notation... but you could have:

let myArray = ["a","b","c","d"];_x000D_
for (let key in myArray) {_x000D_
  let value =  myArray[key]; // get the value by key_x000D_
  console.log("key: %o, value: %o", key, value);_x000D_
}

_{¹ Unfortunately, someone may have added enumerable properties to the array or its prototype chain which are not numeric indices... or they may have assigned an index leaving unassigned indices in the interim range. The issues are explained pretty well here. The main takeaway is that it's best to loop explicitly from 0 to array.length - 1 rather than using for...in.}

So, this is not (as I'd originally thought) an academic question, i.e.:

Without regard for practicality, is it possible to avoid length when iterating over an array?

According to your comment (emphasis mine):

[...] why do I need to calculate the size of an array whereas the interpreter can know it.

You have a misguided aversion to Array.length. It's not calculated on the fly; it's updated whenever the length of the array changes. You're not going to see performance gains by avoiding it (apart from caching the array length rather than accessing the property):

Now, even if you did get some marginal performance increase, I doubt it would be enough to justify the risk of dealing with the aforementioned issues.

Hello world

See:
http://docs.docker.com/userguide/dockerizing/

a full example with data and 2 groups follows:

Imports:

from StringIO import StringIO
import pandas as pd
#pandas config
pd.set_option('display.max_rows', 20)

Data example with 2 groups: G1:Group 1. G2: Group 2:

TESTDATA = StringIO("""G1;G2;Value
1;A;1.6
1;A;5.1
1;A;7.1
1;A;8.1

1;B;21.1
1;B;22.1
1;B;24.1
1;B;30.6

2;A;40.6
2;A;51.1
2;A;52.1
2;A;60.6

2;B;80.1
2;B;70.6
2;B;90.6
2;B;85.1
""")

Read text data to pandas dataframe:

df = pd.read_csv(TESTDATA, sep=";")

Define the outliers using standard deviations

stds = 1.0
outliers = df[['G1', 'G2', 'Value']].groupby(['G1','G2']).transform(
           lambda group: (group - group.mean()).abs().div(group.std())) > stds

Define filtered data values and the outliers:

dfv = df[outliers.Value == False]
dfo = df[outliers.Value == True]

Print the result:

print '\n'*5, 'All values with decimal 1 are non-outliers. In the other hand, all values with 6 in the decimal are.'
print '\nDef DATA:\n%s\n\nFiltred Values with %s stds:\n%s\n\nOutliers:\n%s' %(df, stds, dfv, dfo)

The sequence is CR (Carriage Return) - LF (Line Feed). Remember dot matrix printers? Exactly. So - the correct order is \r \n

I adopted a SQL 2012 database where I was not a sysadmin but was an administrator on the machine. I used SSMS with "Run as Administrator", added my NT account as a SQL login and set the server role to sysadmin. No problem.

For better display with printed document or a report, we need to remove the button as well, and the ability to show or hide certain code blocks. Here's what I use (simply copy-paste this to your first cell):

# This is a cell to hide code snippets from displaying
# This must be at first cell!

from IPython.display import HTML

hide_me = ''
HTML('''<script>
code_show=true; 
function code_toggle() {
  if (code_show) {
    $('div.input').each(function(id) {
      el = $(this).find('.cm-variable:first');
      if (id == 0 || el.text() == 'hide_me') {
        $(this).hide();
      }
    });
    $('div.output_prompt').css('opacity', 0);
  } else {
    $('div.input').each(function(id) {
      $(this).show();
    });
    $('div.output_prompt').css('opacity', 1);
  }
  code_show = !code_show
} 
$( document ).ready(code_toggle);
</script>
<form action="javascript:code_toggle()"><input style="opacity:0" type="submit" value="Click here to toggle on/off the raw code."></form>''')

Then in your next cells:

hide_me
print "this code will be hidden"

and

print "this code will be shown"

You need to set the return value of setInterval to a variable within the scope of the click handler, then use clearInterval() like this:

var interval = null;
$(document).on('ready',function(){
    interval = setInterval(updateDiv,3000);
});

function updateDiv(){
    $.ajax({
        url: 'getContent.php',
        success: function(data){
            $('.square').html(data);
        },
        error: function(){
            clearInterval(interval); // stop the interval
            $.playSound('oneday.wav');
            $('.square').html('<span style="color:red">Connection problems</span>');
        }
    });
}

Yes you can pass variable no. of arguments to a function. You can use apply to achieve this.

E.g.:

var arr = ["Hi","How","are","you"];

function applyTest(){
    var arg = arguments.length;
    console.log(arg);
}

applyTest.apply(null,arr);
