Hmm, I would suggest that you use Flyweight to implement the states. Purpose: Avoid the memory overhead of a large number of small objects. State machines can get very, very big.

http://en.wikipedia.org/wiki/Flyweight_pattern

I'm not sure that I see the need to use design pattern State to implement the nodes. The nodes in a state machine are stateless. They just match the current input symbol to the available transitions from the current state. That is, unless I have entirely forgotten how they work (which is a definite possiblilty).

If I were coding it, I would do something like this:

interface FsmNode {
  public boolean canConsume(Symbol sym);
  public FsmNode consume(Symbol sym);
  // Other methods here to identify the state we are in
}

  List<Symbol> input = getSymbols();
  FsmNode current = getStartState();
  for (final Symbol sym : input) {
    if (!current.canConsume(sym)) {
      throw new RuntimeException("FSM node " + current + " can't consume symbol " + sym);
    }
    current = current.consume(sym);
  }
  System.out.println("FSM consumed all input, end state is " + current);

What would Flyweight do in this case? Well, underneath the FsmNode there would probably be something like this:

Map<Integer, Map<Symbol, Integer>> fsm; // A state is an Integer, the transitions are from symbol to state number
FsmState makeState(int stateNum) {
  return new FsmState() {
    public FsmState consume(final Symbol sym) {
      final Map<Symbol, Integer> transitions = fsm.get(stateNum);
      if (transisions == null) {
        throw new RuntimeException("Illegal state number " + stateNum);
      }
      final Integer nextState = transitions.get(sym);  // May be null if no transition
      return nextState;
    }
    public boolean canConsume(final Symbol sym) {
      return consume(sym) != null;
    }
  }
}

This creates the State objects on a need-to-use basis, It allows you to use a much more efficient underlying mechanism to store the actual state machine. The one I use here (Map(Integer, Map(Symbol, Integer))) is not particulary efficient.

Note that the Wikipedia page focuses on the cases where many somewhat similar objects share the similar data, as is the case in the String implementation in Java. In my opinion, Flyweight is a tad more general, and covers any on-demand creation of objects with a short life span (use more CPU to save on a more efficient underlying data structure).

I used the copy command with the /z switch for copying over network drives. Also works for copying between local drives. Tested on XP Home edition.

also happens when you use jinja templates (which have different syntax for calling object methods) and you forget to set it in settings.py

To answer your question about getting the URL to use for urllib, just execute this JavaScript code:

url = browser.execute_script("return window.location;")

The JUnit way is to do this at run-time is org.junit.Assume.

 @Before
 public void beforeMethod() {
     org.junit.Assume.assumeTrue(someCondition());
     // rest of setup.
 }

You can do it in a @Before method or in the test itself, but not in an @After method. If you do it in the test itself, your @Before method will get run. You can also do it within @BeforeClass to prevent class initialization.

An assumption failure causes the test to be ignored.

Edit: To compare with the @RunIf annotation from junit-ext, their sample code would look like this:

@Test
public void calculateTotalSalary() {
    assumeThat(Database.connect(), is(notNull()));
    //test code below.
}

Not to mention that it is much easier to capture and use the connection from the Database.connect() method this way.

You can do this a couple of ways.

Via the "Solution Explorer"

1. Simply right-click the "References" folder and select "Manage NuGet Packages..."
2. Once that window comes up click on the option labeled "Online" in the left most part of the dialog.
3. Then in the search bar in the upper right type "json.net"
4. Click "Install" and you're done.

Via the "Package Manager Console"

1. Open the console. "View" > "Other Windows" > "Package Manager Console"
2. Then type the following:

   Install-Package Newtonsoft.Json

For more info on how to use the "Package Manager Console" check out the nuget docs.

Given the right programmer, Assembler programs can always be made faster than their C counterparts (at least marginally). It would be difficult to create a C program where you couldn't take out at least one instruction of the Assembler.

For all solutions instead of ".keyup" ".change" should be used or else the submit button wont be disabled when someone just selects data stored in cookies for any of the text fields.

Based on Lance Larsen answer - here's an extension method with the recommended string.Compare instead of string.Equals

It is highly recommended that you use an overload of String.Compare that takes a StringComparison parameter. Not only do these overloads allow you to define the exact comparison behavior you intended, using them will also make your code more readable for other developers. [Josh Free @ BCL Team Blog]

public static bool Contains(this List<string> source, string toCheck, StringComparison comp)
{
    return
       source != null &&
       !string.IsNullOrEmpty(toCheck) &&
       source.Any(x => string.Compare(x, toCheck, comp) == 0);
}

Add

<item name="android:windowNoTitle">true</item>

inside AppTheme (styles.xml)

It's somewhat cleaner as the other solutions because it doesn't use any hacks nor depends on Browser JS functions, e.g. works also in other JS environments.

A view uses a query to pull data from the underlying tables.

A materialized view is a table on disk that contains the result set of a query.

Materialized views are primarily used to increase application performance when it isn't feasible or desirable to use a standard view with indexes applied to it. Materialized views can be updated on a regular basis either through triggers or by using the ON COMMIT REFRESH option. This does require a few extra permissions, but it's nothing complex. ON COMMIT REFRESH has been in place since at least Oracle 10.

The above steps

conda install -c conda-forge tensorflow

will work for Windows 10 as well but the Python version should be 3.5 or above. I have used it with Anaconda Python version 3.6 as the protocol buffer format it refers to available on 3.5 or above. Thanks, Sandip

Note: Since someone claimed that the external link is dead in Sushant Butta's answer I've posted the content here as a separate answer.

Beware of NULLS.

Today I came across a very strange behaviour of query while using IN and NOT IN operators. Actually I wanted to compare two tables and find out whether a value from table b existed in table a or not and find out its behavior if the column containsnull values. So I just created an environment to test this behavior.

We will create table table_a.

SQL> create table table_a ( a number);
Table created.

We will create table table_b.

SQL> create table table_b ( b number);
Table created.

Insert some values into table_a.

SQL> insert into table_a values (1);
1 row created.

SQL> insert into table_a values (2);
1 row created.

SQL> insert into table_a values (3);
1 row created.

Insert some values into table_b.

SQL> insert into table_b values(4);
1 row created.

SQL> insert into table_b values(3);
1 row created.

Now we will execute a query to check the existence of a value in table_a by checking its value from table_b using IN operator.

SQL> select * from table_a where a in (select * from table_b);
         A
----------
         3

Execute below query to check the non existence.

SQL> select * from table_a where a not in (select * from table_b);
         A
----------
         1
         2

The output came as expected. Now we will insert a null value in the table table_b and see how the above two queries behave.

SQL> insert into table_b values(null);
1 row created.

SQL> select * from table_a where a in (select * from table_b);
         A
----------
         3

SQL> select * from table_a where a not in (select * from table_b);

no rows selected

The first query behaved as expected but what happened to the second query? Why didn't we get any output, what should have happened? Is there any difference in the query? No.

The change is in the data of table table_b. We have introduced a null value in the table. But how come it's behaving like this? Let's split the two queries into "AND" and "OR" operator.

First Query:

The first query will be handled internally something like this. So a null will not create a problem here as my first two operands will either evaluate to true or false. But my third operand a = null will neither evaluate to true nor false. It will evaluate to null only.

select * from table_a whara a = 3 or a = 4 or a = null;

a = 3  is either true or false
a = 4  is either true or false
a = null is null

Second Query:

The second query will be handled as below. Since we are using an "AND" operator and anything other than true in any of the operand will not give me any output.

select * from table_a whara a <> 3 and a <> 4 and a <> null;

a <> 3 is either true or false
a <> 4 is either true or false
a <> null is null

So how do we handle this? We will pick all the not null values from table table_b while using NOT IN operator.

SQL> select * from table_a where a not in (select * from table_b where b is not null);

         A
----------
         1
         2

So always be careful about NULL values in the column while using NOT IN operator.

Beware of NULL!!

I've used regex a number of times, but I always have to relearn it each time, which is frustrating :-)

So Here's a non-regex solution:

function csvRowToArray(row, delimiter = ',', quoteChar = '"'){
    let nStart = 0, nEnd = 0, a=[], nRowLen=row.length, bQuotedValue;
    while (nStart <= nRowLen) {
        bQuotedValue = (row.charAt(nStart) === quoteChar);
        if (bQuotedValue) {
            nStart++;
            nEnd = row.indexOf(quoteChar + delimiter, nStart)
        } else {
            nEnd = row.indexOf(delimiter, nStart)
        }
        if (nEnd < 0) nEnd = nRowLen;
        a.push(row.substring(nStart,nEnd));
        nStart = nEnd + delimiter.length + (bQuotedValue ? 1 : 0)
    }
    return a;
}

How it works:

1. Pass in the csv string in row.
2. While the start position of the next value is within the row, do the following:
   • If this value has been quoted, set nEnd to the closing quote.
   • Else if value has NOT been quoted, set nEnd to the next delimiter.
   • Add the value to an array.
   • Set nStart to nEnd plus the length of the delimeter.

Sometimes it's good to write your own small function, rather than use a library. Your own code is going to perform well and use only a small footprint. In addition, you can easily tweak it to suit your own needs.

The actual problem is with your

showList function.

There is an extra ')' after 'visible'.

Remove that and it will work fine.

function showList()
{
  if (document.getElementById("favSports").style.visibility == "hidden") 
    {
       // document.getElementById("favSports").style.visibility = "visible");  
       // your code
       document.getElementById("favSports").style.visibility = "visible";
       // corrected code
    }
}

Make an /login url, than accept "user" and "password" parameters via GET and don't require basic auth. Here, use php, node, java, whatever and parse your passwd file and match parameters (user/pass) against it. If there is a match then redirect to http://user:[email protected]/ (this will set credential on your browser) if not, send 401 response (without WWW-Authenticate header).

easy as py:

class Downloder():
    def download_manager(self, url, destination='Files/DownloderApp/', try_number="10", time_out="60"):
        #threading.Thread(target=self._wget_dl, args=(url, destination, try_number, time_out, log_file)).start()
        if self._wget_dl(url, destination, try_number, time_out, log_file) == 0:
            return True
        else:
            return False


    def _wget_dl(self,url, destination, try_number, time_out):
        import subprocess
        command=["wget", "-c", "-P", destination, "-t", try_number, "-T", time_out , url]
        try:
            download_state=subprocess.call(command)
        except Exception as e:
            print(e)
        #if download_state==0 => successfull download
        return download_state

I had the same issue when migrating from Visual Studio 2017 to 2019. I had to reinstall Microsoft.NET.Test.Sdk in all my test projects.

I just ran into this same problem but had a different fix. Essentially I had both SQL Server and SQL Server Express installed on my computer. This wouldn't work when I attempted to restore to SQL Express, but worked correctly when I restored it to SQL Server.

The shell function.

You can use shell function: current_dir = $(shell pwd). Or shell in combination with notdir, if you need not absolute path: current_dir = $(notdir $(shell pwd)).

Update.

Given solution only works when you are running make from the Makefile's current directory.
As @Flimm noted:

Note that this returns the current working directory, not the parent directory of the Makefile.
For example, if you run cd /; make -f /home/username/project/Makefile, the current_dir variable will be /, not /home/username/project/.

Code below will work for Makefiles invoked from any directory:

mkfile_path := $(abspath $(lastword $(MAKEFILE_LIST)))
current_dir := $(notdir $(patsubst %/,%,$(dir $(mkfile_path))))

You can also drop the column and its constraint(s) in a single statement rather than individually.

CREATE TABLE #T
  (
     Col1 INT CONSTRAINT UQ UNIQUE CONSTRAINT CK CHECK (Col1 > 5),
     Col2 INT
  )

ALTER TABLE #T DROP CONSTRAINT UQ , 
                    CONSTRAINT CK, 
                    COLUMN Col1


DROP TABLE #T 

Some dynamic SQL that will look up the names of dependent check constraints and default constraints and drop them along with the column is below

(but not other possible column dependencies such as foreign keys, unique and primary key constraints, computed columns, indexes)

CREATE TABLE [dbo].[TestTable]
(
A INT DEFAULT '1' CHECK (A=1),
B INT,
CHECK (A > B)
)

GO

DECLARE @TwoPartTableNameQuoted nvarchar(500) = '[dbo].[TestTable]',
        @ColumnNameUnQuoted sysname = 'A',
        @DynSQL NVARCHAR(MAX);

SELECT @DynSQL =
     'ALTER TABLE ' + @TwoPartTableNameQuoted + ' DROP' + 
      ISNULL(' CONSTRAINT ' + QUOTENAME(OBJECT_NAME(c.default_object_id)) + ',','') + 
      ISNULL(check_constraints,'') + 
      '  COLUMN ' + QUOTENAME(@ColumnNameUnQuoted)
FROM   sys.columns c
       CROSS APPLY (SELECT ' CONSTRAINT ' + QUOTENAME(OBJECT_NAME(referencing_id)) + ','
                    FROM   sys.sql_expression_dependencies
                    WHERE  referenced_id = c.object_id
                           AND referenced_minor_id = c.column_id
                           AND OBJECTPROPERTYEX(referencing_id, 'BaseType') = 'C'
                    FOR XML PATH('')) ck(check_constraints)
WHERE  c.object_id = object_id(@TwoPartTableNameQuoted)
       AND c.name = @ColumnNameUnQuoted;

PRINT @DynSQL;
EXEC (@DynSQL); 

I know this has been answered, but TypeScript introduced type guards: https://www.typescriptlang.org/docs/handbook/advanced-types.html#typeof-type-guards

If you have a type like: Object[] | string[] and what to do something conditionally based on what type it is - you can use this type guarding:

function isStringArray(value: any): value is string[] {
  if (value instanceof Array) {
    value.forEach(function(item) { // maybe only check first value?
      if (typeof item !== 'string') {
        return false
      }
    })
    return true
  }
  return false
}

function join<T>(value: string[] | T[]) {
  if (isStringArray(value)) {
    return value.join(',') // value is string[] here
  } else {
    return value.map((x) => x.toString()).join(',') // value is T[] here
  }
}

There is an issue with an empty array being typed as string[], but that might be okay

One of the differences is in short

UDP : Send message and dont look back if it reached destination, Connectionless protocol
TCP : Send message and guarantee to reach destination, Connection-oriented protocol

You can use the os/signal package to handle incoming signals. Ctrl+C is SIGINT, so you can use this to trap os.Interrupt.

c := make(chan os.Signal, 1)
signal.Notify(c, os.Interrupt)
go func(){
    for sig := range c {
        // sig is a ^C, handle it
    }
}()

The manner in which you cause your program to terminate and print information is entirely up to you.

To fix this problem, you have to install OpenSSL development package, which is available in standard repositories of all modern Linux distributions.

To install OpenSSL development package on Debian, Ubuntu or their derivatives:

$ sudo apt-get install libssl-dev

To install OpenSSL development package on Fedora, CentOS or RHEL:

$ sudo yum install openssl-devel 

Edit : As @isapir has pointed out, for Fedora version>=22 use the DNF package manager :

dnf install openssl-devel

An SMS Push is a message to tell the terminal to initiate the session. This happens because you can't initiate an IP session simply because you don't know the IP Adress of the mobile terminal. Mostly used to send a few lines of data to end recipient, to the effect of sending information, or reminding of events.

WAP Push is an SMS within the header of which is included a link to a WAP address. On receiving a WAP Push, the compatible mobile handset automatically gives the user the option to access the WAP content on his handset. The WAP Push directs the end-user to a WAP address where content is stored ready for viewing or downloading onto the handset. This wap address may be a page or a WAP site.

The user may “take action” by using a developer-defined soft-key to immediately activate an application to accomplish a specific task, such as downloading a picture, making a purchase, or responding to a marketing offer.

I was very frustrated trying to achieve a fitty-like tight text wrapping so I ended up using a canvas-based method which I arrived at by unsuccessfully trying other methods. What I was aiming for looks like the attached which turns out to be surprisingly difficult (for me). Hopefully one day we will have a simple CSS-only way of doing this. Downsides of this approach is the text is treated more like an image, but for some use cases this is fine.

https://codesandbox.io/s/create-a-canvas-tightly-holding-a-word-st2h1?file=/index.html

This image is a screenshot of a CSS Grid layout of four full-bleed canvases.

Works the best. If you want to use it sitewide, without having to add this syntax to every class or ID, add the following CSS to your css body:

body { 
    -webkit-font-smoothing: antialiased;
    text-shadow: 1px 1px 1px rgba(0,0,0,0.004);
    background: url('./images/background.png');
    text-align: left;
    margin: auto;

}

The easiest way is to JSON-encode your object and then decode it back to an array:

$array = json_decode(json_encode($object), true);

Or if you prefer, you can traverse the object manually, too:

foreach ($object as $value) 
    $array[] = $value->post_id;

For macOS catalina try this : open Xcode. if not existing. download from App store (about 11GB) then open Xcode>open developer tool>more developer tool and used my apple id to download a compatible command line tool. Then, after downloading, I opened Xcode>Preferences>Locations>Command Line Tool and selected the newly downloaded command line tool from downloads.

I found this to be a lot easier

from dateutil import relativedelta
relativedelta.relativedelta(end_time,start_time).seconds

You could find the difference between dates in columns in a data frame by using the function difftime as follows:

df$diff_in_days<- difftime(df$datevar1 ,df$datevar2 , units = c("days"))

The way that Magento themes handle actual url's is as such (in view partials - phtml files):

echo $this->getSkinUrl('images/logo.png');

If you need the actual base path on disk to the image directory use:

echo Mage::getBaseDir('skin');

Some more base directory types are available in this great blog post:

http://alanstorm.com/magento_base_directories

I want to make clear that new Date().getTime() does in fact return a UTC value, so it is a really helpful way to store and manage dates in a way that is agnostic to localized times.

In other words, don't bother with all the UTC javascript functions. Instead, just use Date.getTime().

More info on the explanation is here: If javascript "(new Date()).getTime()" is run from 2 different Timezones.

You cannot store arrays in vectors (or in any other standard library container). The things that standard library containers store must be copyable and assignable, and arrays are neither of these.

If you really need to put an array in a vector (and you probably don't - using a vector of vectors or a vector of strings is more likely what you need), then you can wrap the array in a struct:

struct S {
  char a[10];
};

and then create a vector of structs:

vector <S> v;
S s;
s.a[0] = 'x';
v.push_back( s );

// Timestamp after converting to milliseconds.

NSString * timeInMS = [NSString stringWithFormat:@"%lld", [@(floor([date timeIntervalSince1970] * 1000)) longLongValue]];

try using

@record.assign_attributes({ ... })
@record.save(validate: false)

works for me

You can assign an id to the specific link and add CSS. See the steps below:

1.Add an id of your choice (must be a unique name; can only start with text, not a number):

<a href="/abc/xyz" id="smallLinkButton">def</a>

2. Then add the necessary CSS as follows:

   #smallLinkButton:hover,active,visited{
   
         text-decoration: none;
         }
   

Below is just a little variant of the script provided by @"Juuso Ohtonen".

I have add a password variable and counter so you can can check the progression of your backup. Also I replaced simple brackets [] by double brackets [[]] to prevent an error I had on macos.

1. Get the total number of keys

$ sudo redis-cli
INFO keyspace
AUTH yourpassword
INFO keyspace

2. Edit the script

#!/bin/bash

# Default to '*' key pattern, meaning all redis keys in the namespace
REDIS_KEY_PATTERN="${REDIS_KEY_PATTERN:-*}"
PASS="yourpassword"
i=1
for key in $(redis-cli -a "$PASS" --scan --pattern "$REDIS_KEY_PATTERN")
do
    echo $i.
    ((i=i+1))
    type=$(redis-cli -a "$PASS" type $key)
    if [[ $type = "list" ]]
    then
        printf "$key => \n$(redis-cli -a "$PASS" lrange $key 0 -1 | sed 's/^/  /')\n"
    elif [[ $type = "hash" ]]
    then
        printf "$key => \n$(redis-cli -a "$PASS" hgetall $key | sed 's/^/  /')\n"
    else
        printf "$key => $(redis-cli -a "$PASS" get $key)\n"
    fi
    echo
done

3. Execute the script

bash redis_print.sh > redis.bak

4. Check progression

tail redis.bak

you should android sdk manager install 4.2 api 17 -> ARM EABI v7a System Image

if not installed ARM EABI v7a System Image, you should install all.

Works even if the default value is a boolean value:

var setVariable = ( (b = 0) => b )( localStorage.getItem('value') );

Just go to php.ini then find short_open_tag= Off set to short_open_tag= On

IF you want to handle 'standard' JSON representation of the Date then better to use this pattern: "yyyy-MM-dd'T'HH:mm:ssX".

Notice the X on the end. It will handle timezones in ISO 8601 standard, and ISO 8601 is exactly what produces this statement in Javascript new Date().toJSON()

Comparing to other answers it has some benefits:

1. You don't need to require your clients to send date in GMT
2. You don't need to explicitly convert your Date object to GMT using this: sdf.setTimeZone(TimeZone.getTimeZone("GMT"));

I had the same issue. I was using the "Power save mode", which prevents from compiling incrementally and showing compilation errors.

Changing the value here doesn't make sense, because it's active field. It means value will be synchronized with the model value.

Just change the value of $model->hidden1 to change it. Or it will be changed after receiving data from user after submitting form.

With using non-active hidden input it will be like that:

use yii\helpers\Html;

...

echo Html::hiddenInput('name', $value);

But the latter is more suitable for using outside of model.

If you are really about to work on multi-gigabyte text files then do not use PowerShell. Even if you find a way to read it faster processing of huge amount of lines will be slow in PowerShell anyway and you cannot avoid this. Even simple loops are expensive, say for 10 million iterations (quite real in your case) we have:

# "empty" loop: takes 10 seconds
measure-command { for($i=0; $i -lt 10000000; ++$i) {} }

# "simple" job, just output: takes 20 seconds
measure-command { for($i=0; $i -lt 10000000; ++$i) { $i } }

# "more real job": 107 seconds
measure-command { for($i=0; $i -lt 10000000; ++$i) { $i.ToString() -match '1' } }

UPDATE: If you are still not scared then try to use the .NET reader:

$reader = [System.IO.File]::OpenText("my.log")
try {
    for() {
        $line = $reader.ReadLine()
        if ($line -eq $null) { break }
        # process the line
        $line
    }
}
finally {
    $reader.Close()
}

UPDATE 2

There are comments about possibly better / shorter code. There is nothing wrong with the original code with for and it is not pseudo-code. But the shorter (shortest?) variant of the reading loop is

$reader = [System.IO.File]::OpenText("my.log")
while($null -ne ($line = $reader.ReadLine())) {
    $line
}

In Python 2.7.3:

import urllib2
import socket

class MyException(Exception):
    pass

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError as e:
    print type(e)    #not catch
except socket.timeout as e:
    print type(e)    #catched
    raise MyException("There was an error: %r" % e)

Try to set date.timezone in php.ini file. Or you can manually set it using ini_set() or date_default_timezone_set().

I found that the following worked for me - instead on using on click, use on change e.g.:

 jQuery('#element select').on('change',  (function() {

       //your code here

}));

You can use the OpenSSL Command line tool. The following commands should do the trick

openssl pkcs12 -in client_ssl.pfx -out client_ssl.pem -clcerts

openssl pkcs12 -in client_ssl.pfx -out root.pem -cacerts

If you want your file to be password protected etc, then there are additional options.

You can read the entire documentation here.

$(document).on('click','[action=register]',function(){
    registerSocket(registerJSON(),registerDone,second($(this)));
});

function registerSocket(dataFn,doneFn,second){
                 $.ajax({
                       type:'POST',
                       url: "http://localhost:8080/store/public/register",
                       contentType: "application/json; charset=utf-8",
                       dataType: "json",
                       data:dataFn
                 }).done ([doneFn,second])
                   .fail(function(err){
                            console.log("AJAX failed: " + JSON.stringify(err, null, 2));
                        });
}

function registerDone(data){
    console.log(JSON.stringify(data));
}
function second(element){
    console.log(element);
}

Secondary way :

function socketWithParam(url,dataFn,doneFn,param){
  $.ajax({
    type:'POST',
    url:url,
    contentType: "application/json; charset=utf-8",
    headers: { 'Authorization': 'Bearer '+localStorage.getItem('jwt')},
    data:dataFn
    }).done(function(data){
      doneFn(data,param);
    })
    .fail(function(err,status,xhr){
    console.log("AJAX failed: " + JSON.stringify(err, null, 2));
    });
}

$(document).on('click','[order-btn]',function(){
  socketWithParam(url,fakeDataFn(),orderDetailDone,secondParam);
});

function orderDetailDone(data,param){
  -- to do something --
}

Just an update for Laravel 5:

In Laravel 4.2:

use Illuminate\Database\Eloquent\SoftDeletingTrait;    
class Post extends Eloquent {

    use SoftDeletingTrait;

    protected $dates = ['deleted_at'];

}

becomes in Laravel 5:

use Illuminate\Database\Eloquent\SoftDeletes;

class User extends Model {

    use SoftDeletes;
    protected $dates = ['deleted_at'];

for Visual Studio 2012, 2013, 2015, 2017 follow the link and download the extension

https://marketplace.visualstudio.com/items?itemName=ctlajoie.DuplicateSelection

Now go into Tools > Options > Keyboard, and type "Duplicate" in the search box (the full command string is "Edit.DuplicateSelection"). Here you can bind it to any shortcut in the same way you would for any other command.

As an alternative, one can rely on the cartesian product provided by itertools: itertools.product, which avoids creating a temporary key or modifying the index:

import numpy as np 
import pandas as pd 
import itertools

def cartesian(df1, df2):
    rows = itertools.product(df1.iterrows(), df2.iterrows())

    df = pd.DataFrame(left.append(right) for (_, left), (_, right) in rows)
    return df.reset_index(drop=True)

Quick test:

In [46]: a = pd.DataFrame(np.random.rand(5, 3), columns=["a", "b", "c"])

In [47]: b = pd.DataFrame(np.random.rand(5, 3), columns=["d", "e", "f"])    

In [48]: cartesian(a,b)
Out[48]:
           a         b         c         d         e         f

or use the AdjustToUniversal DateTimeStyle in a call to

DateTime.ParseExact(String, String[], IFormatProvider, DateTimeStyles)

I had this problem on Android L developer preview, and, at least for this version, I solved it by creating an sdcard with a size that had square 2 size (e.g 128M, 256M etc)

Your call_python_file.php should look like this:

<?php
    $item='Everything is awesome!!';
    $tmp = exec("py.py $item");
    echo $tmp;
?>

This executes the python script and outputs the result to the browser. While in your python script the (sys.argv[1:]) variable will bring in all your arguments. To display the argv as a string for wherever your php is pulling from so if you want to do a text area:

import sys

list1 = ' '.join(sys.argv[1:])

def main():
  print list1

if __name__ == '__main__':
    main()

Safest way :

static_cast<int>(reinterpret_cast<long>(void * your_variable));

long guarantees a pointer size on Linux on any machine. Windows has 32 bit long only on 64 bit as well. Therefore, you need to change it to long long instead of long in windows for 64 bits. So reinterpret_cast has casted it to long type and then static_cast safely casts long to int, if you are ready do truncte the data.

I think that in this case using polar coordinates is a way of complicate the problem, it would be much easier if you pick random points into a square with sides of length 2R and then select the points (x,y) such that x^2+y^2<=R^2.

if there are multiple java processes and you wish to kill them with one command try the below command

kill -9 $(ps -ef | pgrep -f "java")

replace "java" with any process string identifier , to kill anything else.

Use .val() not attr('value').

You need to precede the lines starting with gcc and rm with a hard tab. Commands in make rules are required to start with a tab (unless they follow a semicolon on the same line). The result should look like this:

PROG = semsearch
all: $(PROG)
%: %.c
        gcc -o $@ $< -lpthread

clean:
        rm $(PROG)

Note that some editors may be configured to insert a sequence of spaces instead of a hard tab. If there are spaces at the start of these lines you'll also see the "missing separator" error. If you do have problems inserting hard tabs, use the semicolon way:

PROG = semsearch
all: $(PROG)
%: %.c ; gcc -o $@ $< -lpthread

clean: ; rm $(PROG)

In Netbeans 8.2

1. Dowload the binaries from the web source. The Apache Commos are in: [http://commons.apache.org/components.html][1] In this case, you must select the "Logging" in the Components menu and follow the link to downloads in the Releases part. Direct URL: [http://commons.apache.org/proper/commons-logging/download_logging.cgi][2] For me, the correct download was the file: commons-logging-1.2-bin.zip from the Binaries.

2. Unzip downloaded content. Now, you can see several jar files inside the directory created from the zip file.

3. Add the library to the project. Right click in the project, select Properties and click in Libraries (in the left side). Click the button "Add Jar/Folder". Go to the previously unzipped contents and select the properly jar file. Clic in "Open" and click in"Ok". The library has been loaded!

Had the same error, with a much newer version of Android Studio (version 4.1) . A fresh install of Android Studio + a fresh "basic Activity" template would run into error type 3 for hours. I am on win 10 - my problem was how to kill the gradle cache. A good answer above showed a screen snapshot from gradle, but i didn't find it in Android Studio 4.1. Also the env vars for gradle had not been set , and the commandline for gradle didn't work. So .. here is how it worked finally. I went to C:\Users\myusername\ .gradle. This has subdir "caches". I deleted everything inside. Worked ! I did close Android Studio before, restarted and then it worked nicely. Ah forgot one thing- i run the device emulator (defauöt device), i.e. no physical device yet.

Do not use @@fetch_status - this will return status from the last cursor in the current connection. Use the example below:

declare @sqCur cursor;
declare @data varchar(1000);
declare @i int = 0, @lastNum int, @rowNum int;
set @sqCur = cursor local static read_only for 
    select
         row_number() over (order by(select null)) as RowNum
        ,Data -- you fields
    from YourIntTable
open @cur
begin try
    fetch last from @cur into @lastNum, @data
    fetch absolute 1 from @cur into @rowNum, @data --start from the beginning and get first value 
    while @i < @lastNum
    begin
        set @i += 1

        --Do your job here
        print @data

        fetch next from @cur into @rowNum, @data
    end
end try
begin catch
    close @cur      --|
    deallocate @cur --|-remove this 3 lines if you do not throw
    ;throw          --|
end catch
close @cur
deallocate @cur

Do you mean the first N items, or the N largest items?

If you want the first:

top5 = sequence[:5]

This also works for the largest N items, assuming that your sequence is sorted in descending order. (Your LINQ example seems to assume this as well.)

If you want the largest, and it isn't sorted, the most obvious solution is to sort it first:

l = list(sequence)
l.sort(reverse=True)
top5 = l[:5]

For a more performant solution, use a min-heap (thanks Thijs):

import heapq
top5 = heapq.nlargest(5, sequence)

1. Right click your project folder.
2. Select Properties.
3. Expand Build option.
4. Select Packaging.
5. Now Clean and Build your project (Shift +F11).
6. jar file will be created at your_project_folder\dist folder.

The easiest way that I know of to get the number of entries in a table is with '#'. #tableName gets the number of entries as long as they are numbered:

tbl={
    [1]
    [2]
    [3]
    [4]
    [5]
}
print(#tbl)--prints the highest number in the table: 5

Sadly, if they are not numbered, it won't work.

 WebConfigurationManager.ConnectionStrings["YourConnectionString"].ProviderName;

In a translation unit within the same namespace, usually at the top:

// foo.h
struct foo
{
    static const std::string s;
};

// foo.cpp
const std::string foo::s = "thingadongdong"; // this is where it lives

// bar.h
namespace baz
{
    struct bar
    {
        static const float f;
    };
}

// bar.cpp
namespace baz
{
    const float bar::f = 3.1415926535;
}

Are you meaning?

data2 <- data1[good,]

With

data1[good]

you're selecting columns in a wrong way (using a logical vector of complete rows).

Consider that parameter pollutant is not used; is it a column name that you want to extract? if so it should be something like

data2 <- data1[good, pollutant]

Furthermore consider that you have to rbind the data.frames inside the for loop, otherwise you get only the last data.frame (its completed.cases)

And last but not least, i'd prefer generating filenames eg with

id <- 1:322
paste0( directory, "/", gsub(" ", "0", sprintf("%3d",id)), ".csv")

A little modified chunk of ?sprintf

The string fmt (in our case "%3d") contains normal characters, which are passed through to the output string, and also conversion specifications which operate on the arguments provided through .... The allowed conversion specifications start with a % and end with one of the letters in the set aAdifeEgGosxX%. These letters denote the following types:

• d: integer

Eg a more general example

    sprintf("I am %10d years old", 25)
[1] "I am         25 years old"
          ^^^^^^^^^^
          |        |
          1       10

The Dim keyword is optional, when we are using it with modifiers- Public, Protected, Friend, Protected Friend,Private,Shared,Shadows,Static,ReadOnly etc. e.g. - Static nTotal As Integer

For reference type, we have to use new keyword to create the new instance of the class or structure. e.g. Dim lblTop As New System.Windows.Forms.Label.

Dim statement can be used with out a datatype when you set Option Infer to On. In that case the compiler infers the data type of a variable from the type of its initialization expression. Example :

Option Infer On

Module SampleMod

Sub Main()

 Dim nExpVar = 5

The above statement is equivalent to- Dim nExpVar As Integer

Just in normal mode press:

• u - undo,
• Ctrl + r - redo changes which were undone (undo the undos).

Undo and Redo

You need to change the sshd_config file in the remote server (probably in /etc/ssh/sshd_config).

Change

PasswordAuthentication no

to

PasswordAuthentication yes

And then restart the sshd daemon.

Short story: ­­­­­­­­­­­­­­­­­­­no.

Introduction

The newest version of the Microsoft Visual J++ development environment supports a language construct called delegates or bound method references. This construct, and the new keywords delegate and multicast introduced to support it, are not a part of the Java^TM programming language, which is specified by the Java Language Specification and amended by the Inner Classes Specification included in the documentation for the JDKTM 1.1 software.

It is unlikely that the Java programming language will ever include this construct. Sun already carefully considered adopting it in 1996, to the extent of building and discarding working prototypes. Our conclusion was that bound method references are unnecessary and detrimental to the language. This decision was made in consultation with Borland International, who had previous experience with bound method references in Delphi Object Pascal.

We believe bound method references are unnecessary because another design alternative, inner classes, provides equal or superior functionality. In particular, inner classes fully support the requirements of user-interface event handling, and have been used to implement a user-interface API at least as comprehensive as the Windows Foundation Classes.

We believe bound method references are harmful because they detract from the simplicity of the Java programming language and the pervasively object-oriented character of the APIs. Bound method references also introduce irregularity into the language syntax and scoping rules. Finally, they dilute the investment in VM technologies because VMs are required to handle additional and disparate types of references and method linkage efficiently.

use loop

  for (int i = 0; i < dt1.Rows.Count; i++)
        {      
           dt2.Rows.Add(dt1.Rows[i][0], dt1.Rows[i][1], ...);//you have to insert all Columns...
        }

send an output parameter like

@newId int output

at the end use

    select @newId = Scope_Identity() 

     return @newId 

There are references to the official docs (DialogFragment Reference) in other answers, but no mention of the example given there:

void showDialog() {
    mStackLevel++;

    // DialogFragment.show() will take care of adding the fragment
    // in a transaction.  We also want to remove any currently showing
    // dialog, so make our own transaction and take care of that here.
    FragmentTransaction ft = getFragmentManager().beginTransaction();
    Fragment prev = getFragmentManager().findFragmentByTag("dialog");
    if (prev != null) {
        ft.remove(prev);
    }
    ft.addToBackStack(null);

    // Create and show the dialog.
    DialogFragment newFragment = MyDialogFragment.newInstance(mStackLevel);
    newFragment.show(ft, "dialog");
}

This removes any currently shown dialog, creates a new DialogFragment with an argument, and shows it as a new state on the back stack. When the transaction is popped, the current DialogFragment and its Dialog will be destroyed, and the previous one (if any) re-shown. Note that in this case DialogFragment will take care of popping the transaction of the Dialog is dismissed separately from it.

For my needs I changed it to:

FragmentManager manager = getSupportFragmentManager();
Fragment prev = manager.findFragmentByTag(TAG);
if (prev != null) {
    manager.beginTransaction().remove(prev).commit();
}

MyDialogFragment fragment = new MyDialogFragment();
fragment.show(manager, TAG);

Kindly delele all folders under the in /.graddle/version/

This is how i solved mine. good luck

This one really sucked.

I tried all of the solutions suggested here but the only thing that worked was to

• create a new database
• run ALTER TABLE old_db.{table_name} RENAME new_db.{table_name} on all of the functioning tables
• run DROP old_db
• create old_db again
• run ALTER TABLE new_db.{table_name} RENAME old_db.{table_name} on all the tables in new_db

Once you have done that you can finally just create the table again that you previously had.

Simple answer: You should use RecyclerView in a situation where you want to show a lot of items, and the number of them is dynamic. ListView should only be used when the number of items is always the same and is limited to the screen size.

You find it harder because you are thinking just with the Android library in mind.

Today there exists a lot of options that help you build your own adapters, making it easy to build lists and grids of dynamic items that you can pick, reorder, use animation, dividers, add footers, headers, etc, etc.

Don't get scared and give a try to RecyclerView, you can starting to love it making a list of 100 items downloaded from the web (like facebook news) in a ListView and a RecyclerView, you will see the difference in the UX (user experience) when you try to scroll, probably the test app will stop before you can even do it.

I recommend you to check this two libraries for making easy adapters:

FastAdapter by mikepenz

FlexibleAdapter by davideas

Since security.disable option is banned from usage there is still a way to achieve it from pure config without touching any class flies (for me it creates convenience with environments manipulation and possibility to activate it with ENV variable) if you use Boot

spring.autoconfigure.exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration

Try creating another full backup after you backup the log w/ truncate_only (IIRC you should do this anyway to maintain the log chain). In simple recovery mode, your log shouldn't grow much anyway since it's effectively truncated after every transaction. Then try specifying the size you want the logfile to be, e.g.

-- shrink log file to c. 1 GB
DBCC SHRINKFILE (Wxlog0, 1000);

The TRUNCATEONLY option doesn't rearrange the pages inside the log file, so you might have an active page at the "end" of your file, which could prevent it from being shrunk.

You can also use DBCC SQLPERF(LOGSPACE) to make sure that there really is space in the log file to be freed.

You can access the MySQL command line with XAMPP for Windows

1. click XAMPP icon to launch its cPanel

2. click on Shell button

3. Type this mysql -h localhost -u root and click enter

C:\WINDOWS\my.ini C:\WINDOWS\my.cnf C:\my.ini C:\my.cnf C:\xampp\mysql\my.ini C:\xampp\mysql\my.cnf C:\xampp\mysql\bin\my.ini C:\xampp\mysql\bin\my.cnf
The following groups are read: mysql client client-server client-mariadb
The following options may be given as the first argument:
--print-defaults        Print the program argument list and exit.
--no-defaults           Don't read default options from any option file.
--defaults-file=#       Only read default options from the given file #.
--defaults-extra-file=# Read this file after the global files are read.

  -?, --help          Display this help and exit.
  -I, --help          Synonym for -?
  --abort-source-on-error
Abort 'source filename' operations in case of errors
  --auto-rehash       Enable automatic rehashing. One doesn't need to use
                      'rehash' to get table and field completion, but startup
                      and reconnecting may take a longer time. Disable with
                      --disable-auto-rehash.
                      (Defaults to on; use --skip-auto-rehash to disable.)
  -A, --no-auto-rehash
                      No automatic rehashing. One has to use 'rehash' to get
                      table and field completion. This gives a quicker start of
                      mysql and disables rehashing on reconnect.
  --auto-vertical-output
                      Automatically switch to vertical output mode if the
                      result is wider than the terminal width.
  -B, --batch         Don't use history file. Disable interactive behavior.
                      (Enables --silent.)
  --character-sets-dir=name
                      Directory for character set files.
  --column-type-info  Display column type information.
  -c, --comments      Preserve comments. Send comments to the server. The
                      default is --skip-comments (discard comments), enable
                      with --comments.
  -C, --compress      Use compression in server/client protocol.
  -#, --debug[=#]     This is a non-debug version. Catch this and exit.
  --debug-check       Check memory and open file usage at exit.
  -T, --debug-info    Print some debug info at exit.
  -D, --database=name Database to use.
  --default-character-set=name
                      Set the default character set.
  --delimiter=name    Delimiter to be used.
  -e, --execute=name  Execute command and quit. (Disables --force and history
                      file.)
  -E, --vertical      Print the output of a query (rows) vertically.
  -f, --force         Continue even if we get an SQL error. Sets
                      abort-source-on-error to 0
  -G, --named-commands
                      Enable named commands. Named commands mean this program's
                      internal commands; see mysql> help . When enabled, the
                      named commands can be used from any line of the query,
                      otherwise only from the first line, before an enter.
                      Disable with --disable-named-commands. This option is
                      disabled by default.
  -i, --ignore-spaces Ignore space after function names.
  --init-command=name SQL Command to execute when connecting to MySQL server.
                      Will automatically be re-executed when reconnecting.
  --local-infile      Enable/disable LOAD DATA LOCAL INFILE.
  -b, --no-beep       Turn off beep on error.
  -h, --host=name     Connect to host.
  -H, --html          Produce HTML output.
  -X, --xml           Produce XML output.
  --line-numbers      Write line numbers for errors.
                      (Defaults to on; use --skip-line-numbers to disable.)
  -L, --skip-line-numbers
                      Don't write line number for errors.
  -n, --unbuffered    Flush buffer after each query.
  --column-names      Write column names in results.
                      (Defaults to on; use --skip-column-names to disable.)
  -N, --skip-column-names
                      Don't write column names in results.
  --sigint-ignore     Ignore SIGINT (CTRL-C).
  -o, --one-database  Ignore statements except those that occur while the
                      default database is the one named at the command line.
  -p, --password[=name]
                      Password to use when connecting to server. If password is
                      not given it's asked from the tty.
  -W, --pipe          Use named pipes to connect to server.
  -P, --port=#        Port number to use for connection or 0 for default to, in
                      order of preference, my.cnf, $MYSQL_TCP_PORT,
                      /etc/services, built-in default (3306).
  --progress-reports  Get progress reports for long running commands (like
                      ALTER TABLE)
                      (Defaults to on; use --skip-progress-reports to disable.)
  --prompt=name       Set the mysql prompt to this value.
  --protocol=name     The protocol to use for connection (tcp, socket, pipe,
                      memory).
  -q, --quick         Don't cache result, print it row by row. This may slow
                      down the server if the output is suspended. Doesn't use
                      history file.
  -r, --raw           Write fields without conversion. Used with --batch.
  --reconnect         Reconnect if the connection is lost. Disable with
                      --disable-reconnect. This option is enabled by default.
                      (Defaults to on; use --skip-reconnect to disable.)
  -s, --silent        Be more silent. Print results with a tab as separator,
                      each row on new line.
  --shared-memory-base-name=name
                      Base name of shared memory.
  -S, --socket=name   The socket file to use for connection.
  --ssl               Enable SSL for connection (automatically enabled with
                      other flags).
  --ssl-ca=name       CA file in PEM format (check OpenSSL docs, implies
                      --ssl).
  --ssl-capath=name   CA directory (check OpenSSL docs, implies --ssl).
  --ssl-cert=name     X509 cert in PEM format (implies --ssl).
  --ssl-cipher=name   SSL cipher to use (implies --ssl).
  --ssl-key=name      X509 key in PEM format (implies --ssl).
  --ssl-crl=name      Certificate revocation list (implies --ssl).
  --ssl-crlpath=name  Certificate revocation list path (implies --ssl).
  --ssl-verify-server-cert
                      Verify server's "Common Name" in its cert against
                      hostname used when connecting. This option is disabled by
                      default.

                      also. Does not work in batch mode. Disable with
                      --disable-tee. This option is disabled by default.
  -u, --user=name     User for login if not current user.
  -U, --safe-updates  Only allow UPDATE and DELETE that uses keys.
  -U, --i-am-a-dummy  Synonym for option --safe-updates, -U.
  -v, --verbose       Write more. (-v -v -v gives the table output format).
  -V, --version       Output version information and exit.
  -w, --wait          Wait and retry if connection is down.
  --connect-timeout=# Number of seconds before connection timeout.
  --max-allowed-packet=#
                      The maximum packet length to send to or receive from
                      server.
  --net-buffer-length=#
                      The buffer size for TCP/IP and socket communication.
  --select-limit=#    Automatic limit for SELECT when using --safe-updates.

  --binary-mode       By default, ASCII '\0' is disallowed and '\r\n' is
                      translated to '\n'. This switch turns off both features,
                      and also turns off parsing of all clientcommands except
                      \C and DELIMITER, in non-interactive mode (for input
                      piped to mysql or loaded using the 'source' command).
                      This is necessary when processing output from mysqlbinlog
                      that may contain blobs.

I started to get the 500 for debug=False in the form of

django.urls.exceptions.NoReverseMatch: Reverse for 'home' not found.
or...
django.urls.exceptions.NoReverseMatch: Reverse for 'about' not found.

when raising django.core.exceptions.ValidationError instead of raising rest_framework.serializers.ValidationError

To be fair, it was already raising a 500 before, but as a ValidationError, with debug=False, this changed into the NoReverseMatch.

There looks to be an issue with the latest version of the pip module pytesseract=0.3.7. I have downgraded it to pytesseract=0.3.6 and don't see the error.

This is the simplest way we can add an element after another one using vanilla javascript

var d1 = document.getElementById('one');
d1.insertAdjacentHTML('afterend', '<div id="two">two</div>');

Reference: https://developer.mozilla.org/en-US/docs/Web/API/Element/insertAdjacentHTML

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.

There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.

I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException and Application.ThreadException, as appropriate.

For reference, it's 2018 and I'm using BS4.1

Try adding data-boundary="viewport" to the button that toggles the dropdown (the one with the class dropdown-toggle). See https://getbootstrap.com/docs/4.1/components/dropdowns/#options

I would also try it this way

1) Create the Java Beans from the JSON schema

2) Use JSON parser libraries to avoid any sort of exception

3) Cast the parse result to the Java object that was created from the initial JSON schema.

Below is an example JSON Schema"

Hope this helps.

A given ID can be only used once in a page. It's invalid HTML to have multiple objects with the same ID, even if they are in different parts of the page.

You could change your HTML to this:

<div id="div1" >
    <input type="text" class="edit1" />
    <input type="text" class="edit2" />
</div>
<div id="div2" >
    <input type="text" class="edit1" />
    <input type="text" class="edit2" />
</div>

Then, you could get the first item in div1 with a CSS selector like this:

#div1 .edit1

On in jQuery:

$("#div1 .edit1")

Or, if you want to iterate the items in one of your divs, you can do it like this:

$("#div1 input").each(function(index) {
    // do something with one of the input objects
});

If I couldn't use a framework like jQuery or YUI, I'd go get Sizzle and include that for it's selector logic (it's the same selector engine as is inside of jQuery) because DOM manipulation is massively easier with a good selector library.

If I couldn't use even Sizzle (which would be a massive drop in developer productivity), you could use plain DOM functions to traverse the children of a given element.

You would use DOM functions like childNodes or firstChild and nextSibling and you'd have to check the nodeType to make sure you only got the kind of elements you wanted. I never write code that way because it's so much less productive than using a selector library.

One approach is to resize the UIImage in code like the following. Note: this code only scales by height, but you can easily adjust the function to scale by width as well.

let targetHeight = CGFloat(28)
let newImage = resizeImage(image: UIImage(named: "Image.png")!, targetHeight: targetHeight)
button.setImage(newImage, for: .normal)

fileprivate func resizeImage(image: UIImage, targetHeight: CGFloat) -> UIImage {
    // Get current image size
    let size = image.size

    // Compute scaled, new size
    let heightRatio = targetHeight / size.height
    let newSize = CGSize(width: size.width * heightRatio, height: size.height * heightRatio)
    let rect = CGRect(x: 0, y: 0, width: newSize.width, height: newSize.height)

    // Create new image
    UIGraphicsBeginImageContextWithOptions(newSize, false, 0)
    image.draw(in: rect)
    let newImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()

    // Return new image
    return newImage!
}

var obj = {
 webSiteName: 'StackOverFlow',
 find: 'anything',
 onDays: ['sun'     // Object "obj" contains array "onDays" 
            ,'mon',
            'tue',
            'wed',
            'thu',
            'fri',
            'sat',
             {name : "jack", age : 34},
              // array "onDays"contains array object "manyNames"
             {manyNames : ["Narayan", "Payal", "Suraj"]}, //                 
           ]
};

Try 'Update Project'. Once I did this, The Run as Java Application option appeared.

You repository is bare, i.e. it does not have a working tree attached to it. You can clone it locally to create a working tree for it, or you could use one of several other options to tell Git where the working tree is, e.g. the --work-tree option for single commands, or the GIT_WORK_TREE environment variable. There is also the core.worktree configuration option but it will not work in a bare repository (check the man page for what it does).

# git --work-tree=/path/to/work/tree checkout master
# GIT_WORK_TREE=/path/to/work/tree git status

You can even use a version range with pip install command. Something like this:

pip install 'stevedore>=1.3.0,<1.4.0'

And if the package is already installed and you want to downgrade it add --force-reinstall like this:

pip install 'stevedore>=1.3.0,<1.4.0' --force-reinstall

When you install anaconda on windows now, it doesn't automatically add Python or Conda to your path so you have to add it yourself.

If you don’t know where your conda and/or python is, you type the following commands into your anaconda prompt

Next, you can add Python and Conda to your path by using the setx command in your command prompt.

Next close that command prompt and open a new one. Congrats you can now use conda and python

I think it's wise to use a textbox with no border and background as an easy and fast way to reach center aligned textblock

<TextBox
TextWrapping="Wrap"
HorizontalContentAlignment="Center"
VerticalContentAlignment="Center"
Background="{x:Null}"
BorderBrush="{x:Null}"
/>

I know this thread is old but I just want to add this here because it helped me alot trying to figure this all out and its clean. The nice thing about this is you could put it in a loop for a batch file that's always running. Server up-time log or something. That's what I use it for anyways. I hope this helps someone someday.

$sDecrypted and $sEncrypted were undefined in your code. See a solution that works (but is not secure!):

STOP!

This example is insecure! Do not use it!

$Pass = "Passwort";
$Clear = "Klartext";        

$crypted = fnEncrypt($Clear, $Pass);
echo "Encrypred: ".$crypted."</br>";

$newClear = fnDecrypt($crypted, $Pass);
echo "Decrypred: ".$newClear."</br>";        

function fnEncrypt($sValue, $sSecretKey)
{
    return rtrim(
        base64_encode(
            mcrypt_encrypt(
                MCRYPT_RIJNDAEL_256,
                $sSecretKey, $sValue, 
                MCRYPT_MODE_ECB, 
                mcrypt_create_iv(
                    mcrypt_get_iv_size(
                        MCRYPT_RIJNDAEL_256, 
                        MCRYPT_MODE_ECB
                    ), 
                    MCRYPT_RAND)
                )
            ), "\0"
        );
}

function fnDecrypt($sValue, $sSecretKey)
{
    return rtrim(
        mcrypt_decrypt(
            MCRYPT_RIJNDAEL_256, 
            $sSecretKey, 
            base64_decode($sValue), 
            MCRYPT_MODE_ECB,
            mcrypt_create_iv(
                mcrypt_get_iv_size(
                    MCRYPT_RIJNDAEL_256,
                    MCRYPT_MODE_ECB
                ), 
                MCRYPT_RAND
            )
        ), "\0"
    );
}

But there are other problems in this code which make it insecure, in particular the use of ECB (which is not an encryption mode, only a building block on top of which encryption modes can be defined). See Fab Sa's answer for a quick fix of the worst problems and Scott's answer for how to do this right.

I had this exact problem and this worked:

plt.savefig(output_dir + '/xyz.png', bbox_inches='tight')

Here is the documentation:

[https://matplotlib.org/3.1.1/api/_as_gen/matplotlib.pyplot.savefig.html][1]

preg_match_all('!\d+!', $some_string, $matches);
$string_of_numbers = implode(' ', $matches[0]);

The first argument in implode in this specific case says "separate each element in matches[0] with a single space." Implode will not put a space (or whatever your first argument is) before the first number or after the last number.

Something else to note is $matches[0] is where the array of matches (that match this regular expression) found are stored.

For further clarification on what the other indexes in the array are for see: http://php.net/manual/en/function.preg-match-all.php

HTML:

  <input id="search" size="10" />

jQuery:

$("#search").focus();

Here's my hacky workaround - generate a console application (.NET Framework) that reads its own name and arguments, and then calls dotnet [nameOfExe].dll [args].

Of course this assumes that .NET is installed on the target machine.

Here's the code. Feel free to copy!

using System;
using System.Diagnostics;
using System.Text;

namespace dotNetLauncher
{
    class Program
    {
        /*
            If you make .NET Core applications, they have to be launched like .NET blah.dll args here
            This is a convenience EXE file that launches .NET Core applications via name.exe
            Just rename the output exe to the name of the .NET Core DLL file you wish to launch
        */
        static void Main(string[] args)
        {
            var exePath = AppDomain.CurrentDomain.BaseDirectory;
            var exeName = AppDomain.CurrentDomain.FriendlyName;
            var assemblyName = exeName.Substring(0, exeName.Length - 4);
            StringBuilder passInArgs = new StringBuilder();
            foreach(var arg in args)
            {
                bool needsSurroundingQuotes = false;
                if (arg.Contains(" ") || arg.Contains("\""))
                {
                    passInArgs.Append("\"");
                    needsSurroundingQuotes = true;
                }
                passInArgs.Append(arg.Replace("\"","\"\""));
                if (needsSurroundingQuotes)
                {
                    passInArgs.Append("\"");
                }

                passInArgs.Append(" ");
            }
            string callingArgs = $"\"{exePath}{assemblyName}.dll\" {passInArgs.ToString().Trim()}";

            var p = new Process
            {
                StartInfo = new ProcessStartInfo("dotnet", callingArgs)
                {
                    UseShellExecute = false
                }
            };

            p.Start();
            p.WaitForExit();
        }
    }
}

for large data set and multiple value drop down it is better to use ng-options rather than ng-repeat.

ng-repeat is slow because it loops over all coming values but ng-options simply display to the select option.

ng-options='state.StateCode as state.StateName for state in States'>

much much faster than

<option ng-repeat="state in States" value="{{state.StateCode}}">
    {{state.StateName }}
</option>

grep matches, grep -v does the inverse. If you need to "match A but not B" you usually use pipes:

grep "${PATT}" file | grep -v "${NOTPATT}"

you can simply call this method in your application class

ProcessLifecycleOwner.get().getLifecycle().addObserver(new LifecycleEventObserver() {
            @Override
            public void onStateChanged(@NonNull LifecycleOwner source, @NonNull Lifecycle.Event event) {
                Log.e(TAG, "onStateChanged: " + event.toString());
            }
        });

Lifecycle.Event will simply return the state of the application

ON_CREATE
ON_START
ON_RESUME
ON_PAUSE
ON_STOP
ON_DESTROY
ON_ANY

it will return ON_PAUSE & ON_STOP when the app goes to background and will return ON_START & ON_RESUME when the app comes to the foreground

I add the following mapping to my ~/.vimrc

map e/ /sdfdskfxxxxy

And in ESC mode, I press e/

You could use .keypress().

For example, consider the HTML:

<form>
  <fieldset>
    <input id="target" type="text" value="Hello there" />
  </fieldset>
</form>
<div id="other">
  Trigger the handler
</div>

The event handler can be bound to the input field:

$("#target").keypress(function() {
  alert("Handler for .keypress() called.");
});

I totally agree with Andy; all depends on how you want it to work.

For anyone else who has a BaseActivity, and a child that extends from it, make sure the super.onCreate() is called first before you do anything. The old Activity would work if you called super.onCreate() afterwards.

Child extends Activity - could call super after you did stuff

@Override
protected void onCreate(Bundle savedInstanceState)
{
    getActionBar().setDisplayHomeAsUpEnabled(true);
    super.onCreate(savedInstanceState);

Child extends AppCompatActivity - ya gotta call super first

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState); //do this first
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

I face the same problem, and think that I do know why this happens.

The gmail account that I use is normally used from India, and the webserver that I use is located in The Netherlands.

Google notifies that there was a login attempt from am unusualy location and requires to login from that location via a web browser.

Furthermore I had to accept suspicious access to the gmail account via https://security.google.com/settings/security/activity

But in the end my problem is not yet solved, because I have to login to gmail from a location in The Netherlands.

I hope this will help you a little! (sorry, I do not read email replies on this email address)

By this way, you hold a form by his ID and throw all his content. This technic is fastiest.

document.forms["id_form"].reset();

Another solution would be to use Empty.

msdn extract:

Returns an empty IEnumerable that has the specified type argument.

IEnumerable<object> a = Enumerable.Empty<object>();

There is a thread on SO about it: Is it better to use Enumerable.Empty() as opposed to new List to initialize an IEnumerable?

If you use an empty array or empty list, those are objects and they are stored in memory. The Garbage Collector has to take care of them. If you are dealing with a high throughput application, it could be a noticeable impact.

Enumerable.Empty does not create an object per call thus putting less load on the GC.

It seems to me that your Hibernate libraries are not found (NoClassDefFoundError: org/hibernate/boot/archive/scan/spi/ScanEnvironment as you can see above).

Try checking to see if Hibernate core is put in as dependency:

<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-core</artifactId>
  <version>5.0.11.Final</version>
  <scope>compile</scope>
</dependency>

Use the WebRequest class

This is to get an image:

Try
    Dim _WebRequest As System.Net.WebRequest = Nothing
    _WebRequest = System.Net.WebRequest.Create(http://api.hostip.info/?ip=68.180.206.184)
Catch ex As Exception
    Windows.Forms.MessageBox.Show(ex.Message)
    Exit Sub
End Try

Try
    _NormalImage = Image.FromStream(_WebRequest.GetResponse().GetResponseStream())
Catch ex As Exception
    Windows.Forms.MessageBox.Show(ex.Message)
    Exit Sub
End Try

This should work

function updatePostID(val)
{
    document.getElementById('PostID').value = val;

    //and probably call document.forms[0].submit();
}

Then have a hidden field or other control for the PostID

@Html.Hidden("PostID", Model.addcomment.PostID)
//OR
@Html.HiddenFor(model => model.addcomment.PostID)

Both commands are correct :

mvn clean install -Pdev1
mvn clean install -P dev1

The problem is most likely not profile activation, but the profile not accomplishing what you expect it to.

It is normal that the command :

mvn help:active-profiles

does not display the profile, because is does not contain -Pdev1. You could add it to make the profile appear, but it would be pointless because you would be testing maven itself.

What you should do is check the profile behavior by doing the following :

1. set activeByDefault to true in the profile configuration,
2. run mvn help:active-profiles (to make sure it is effectively activated even without -Pdev1),
3. run mvn install.

It should give the same results as before, and therefore confirm that the problem is the profile not doing what you expect.

As other have said, compiled and interpreted are specific to an implementation of a programming language; they are not inherent in the language. For example, there are C interpreters.

However, we can (and in practice we do) classify programming languages based on its most common (sometimes canonical) implementation. For example, we say C is compiled.

First, we must define without ambiguity interpreters and compilers:

An interpreter for language X is a program (or a machine, or just some kind of mechanism in general) that executes any program p written in language X such that it performs the effects and evaluates the results as prescribed by the specification of X.

A compiler from X to Y is a program (or a machine, or just some kind of mechanism in general) that translates any program p from some language X into a semantically equivalent program p' in some language Y in such a way that interpreting p' with an interpreter for Y will yield the same results and have the same effects as interpreting p with an interpreter for X.

Notice that from a programmer point of view, CPUs are machine interpreters for their respective native machine language.

Now, we can do a tentative classification of programming languages into 3 categories depending on its most common implementation:

• Hard Compiled languages: When the programs are compiled entirely to machine language. The only interpreter used is a CPU. Example: Usually, to run a program in C, the source code is compiled to machine language, which is then executed by a CPU.
• Interpreted languages: When there is no compilation of any part of the original program to machine language. In other words, no new machine code is generated; only existing machine code is executed. An interpreter other than the CPU must also be used (usually a program).Example: In the canonical implementation of Python, the source code is compiled first to Python bytecode and then that bytecode is executed by CPython, an interpreter program for Python bytecode.
• Soft Compiled languages: When an interpreter other than the CPU is used but also parts of the original program may be compiled to machine language. This is the case of Java, where the source code is compiled to bytecode first and then, the bytecode may be interpreted by the Java Interpreter and/or further compiled by the JIT compiler.

Sometimes, soft and hard compiled languages are refered to simply compiled, thus C#, Java, C, C++ are said to be compiled.

Within this categorization, JavaScript used to be an interpreted language, but that was many years ago. Nowadays, it is JIT-compiled to native machine language in most major JavaScript implementations so I would say that it falls into soft compiled languages.

If you structure your project this way:

src\
  __init__.py
  main.py
  dirFoo\
    __init__.py
    Foo.py
  dirBar\
    __init__.py
    Bar.py

Then from Foo.py you should be able to do:

import dirFoo.Foo

Or:

from dirFoo.Foo import FooObject

Per Tom's comment, this does require that the src folder is accessible either via site_packages or your search path. Also, as he mentions, __init__.py is implicitly imported when you first import a module in that package/directory. Typically __init__.py is simply an empty file.

    new String(new char[] { 65 })

You will end up with a string of length one, whose single character has the (ASCII) code 65. In Java chars are numeric data types.

If you just want something more simple, you can just change:

<p:panelGrid >

</p:panelGrid>

to:

<h:panelGrid border="0">

</h:panelGrid>

That's worked fine for me

You can use select ... into ... to create and populate a temp table and then query the temp table to return the result.

select *
into #TempTable
from YourTable

select *
from #TempTable

Use string interpolation instead.

print '%d   %f' % (count,conv)

None of the answers above worked for me. In the end I figured out it was an configuration error (I used the android SDK and not Java SDK for compilation).

Got to [Right Click on Project] --> Open Module Settings --> Module --> [Dependendecies] and make sure you have configured and selected the Java SDK (not the android java sdk)

Here's a pure VBA solution because Excel can hold joined cells:

Public Function GetIndexForColumn(Column As String) As Long
    Dim astrColumn()    As String
    Dim Result          As Long
    Dim i               As Integer
    Dim n               As Integer

    Column = UCase(Column)
    ReDim astrColumn(Len(Column) - 1)
    For i = 0 To (Len(Column) - 1)
        astrColumn(i) = Mid(Column, (i + 1), 1)
    Next
    n = 1
    For i = UBound(astrColumn) To 0 Step -1
        Result = (Result + ((Asc(astrColumn(i)) - 64) * n))
        n = (n * 26)
    Next
    GetIndexForColumn = Result
End Function

Basically, this function does the same as any Hex to Dec function, except that it only takes alphabetical chars (A = 1, B = 2, ...). The rightmost char counts single, each char to the left counts 26 times the char right to it (which makes AA = 27 [1 + 26], AAA = 703 [1 + 26 + 676]). The use of UCase() makes this function case-insensitive.

Window -> Preferences -> General -> Workspace : Text file encoding

Haven't tried yet but found WebKit.NET on SourceForge. It was moved to GitHub.

Warning: Not maintained anymore, last commits are from early 2013

No need to do your own implementation. I can recommend using geolocationmarker from google-maps-utility-library-v3.

You can use

$window.scrollTo(x, y);

where x is the pixel along the horizontal axis and y is the pixel along the vertical axis.

1. Scroll to top

   $window.scrollTo(0, 0);
   

2. Focus on element

   $window.scrollTo(0, angular.element('put here your element').offsetTop);   
   

Example

Update:

Also you can use $anchorScroll

Example

You need to make some changes in the compiler. In Dev C++ Compiler: 1. Go to compiler settings/compiler Options. 2. Click on General Tab 3. Check the checkbox (Add the following commands when calling the compiler. 4. write -std=c++11 5. click Ok

If the class is marked final, it means that the class' structure can't be modified by anything external. Where this is the most visible is when you're doing traditional polymorphic inheritance, basically class B extends A just won't work. It's basically a way to protect some parts of your code (to extent).

To clarify, marking class final doesn't mark its fields as final and as such doesn't protect the object properties but the actual class structure instead.

I have found that the Worksheet ".UsedRange" method is superior in many instances to solve this problem. I struggled with a truncation issue that is a normal behaviour of the ".CurrentRegion" method. Using [ Worksheets("Sheet1").Range("A1").CurrentRegion ] does not yield the results I desired when the worksheet consists of one column with blanks in the rows (and the blanks are wanted). In this case, the ".CurrentRegion" will truncate at the first record. I implemented a work around but recently found an even better one; see code below that allows copying the whole set to another sheet or to identify the actual address (or just rows and columns):

Sub mytest_GetAllUsedCells_in_Worksheet()
    Dim myRange

    Set myRange = Worksheets("Sheet1").UsedRange
    'Alternative code:  set myRange = activesheet.UsedRange

   'use msgbox or debug.print to show the address range and counts
   MsgBox myRange.Address      
   MsgBox myRange.Columns.Count
   MsgBox myRange.Rows.Count

  'Copy the Range of data to another sheet
  'Note: contains all the cells with that are non-empty
   myRange.Copy (Worksheets("Sheet2").Range("A1"))
   'Note:  transfers all cells starting at "A1" location.  
   '       You can transfer to another area of the 2nd sheet
   '       by using an alternate starting location like "C5".

End Sub

Because the people who designed the library format didn't want to "waste" space for rarely used information like C preprocessor macros and function declarations.

Since you need that info to tell your compiler "this function is available later when the linker is doing its job", they had to come up with a second file where this shared information could be stored.

Most languages after C/C++ store this information in the output (Java bytecode, for example) or they don't use a precompiled format at all, get always distributed in source form and compile on the fly (Python, Perl).

What happens is that your close button is placed inside your .clickable div, so the click event will be triggered in both elements.

The event bubbling will make the click event propagate from the child nodes to their parents. So your .close_button callback will be executed first, and when .clickable is reached, it will toggle the classes again. As this run very fast you can't notice the two events happened.

                    / \
--------------------| |-----------------
| .clickable        | |                |
|   ----------------| |-----------     |
|   | .close_button | |          |     |
|   ------------------------------     |
|             event bubbling           |
----------------------------------------

To prevent your event from reaching .clickable, you need to add the event parameter to your callback function and then call the stopPropagation method on it.

$(".close_button").click(function (e) { 
    $("#spot1").addClass("spot");
    $("#spot1").removeClass("grown");
    e.stopPropagation();
});

According to Microsoft they are the same thing.

When false, User ID and Password are specified in the connection. When true, the current Windows account credentials are used for authentication.
Recognized values are true, false, yes, no, and sspi (strongly recommended), which is equivalent to true.

If you are using a Route::group, with a vendor plugin like LaravelLocalization (from MCAMARA), you need to put POST routes outside of this group. I've experienced problems with POST routes using this plugin and I did solved right now by putting these routes outside Route::group..

for me $('#element').val('...').change() is the best way.

My solution to this was to write the script block dynamically with [scriptblock]:Create:

# Or build a complex local script with MARKERS here, and do substitutions
# I was sending install scripts to the remote along with MSI packages
# ...for things like Backup and AV protection etc.

$p1 = "good stuff"; $p2 = "better stuff"; $p3 = "best stuff"; $etc = "!"
$script = [scriptblock]::Create("MyScriptOnRemoteServer.ps1 $p1 $p2 $etc")
#strings get interpolated/expanded while a direct scriptblock does not

# the $parms are now expanded in the script block itself
# ...so just call it:
$result = invoke-command $computer -script $script

Passing arguments was very frustrating, trying various methods, e.g.,
-arguments, $using:p1, etc. and this just worked as desired with no problems.

Since I control the contents and variable expansion of the string which creates the [scriptblock] (or script file) this way, there is no real issue with the "invoke-command" incantation.

(It shouldn't be that hard. :) )

The only way to override inline style is by using !important keyword beside the CSS rule. The following is an example of it.

div {
        color: blue !important;
       /* Adding !important will give this rule more precedence over inline style */
    }

<div style="font-size: 18px; color: red;">
    Hello, World. How can I change this to blue?
</div>

Important Notes:

• Using !important is not considered as a good practice. Hence, you should avoid both !important and inline style.

• Adding the !important keyword to any CSS rule lets the rule forcefully precede over all the other CSS rules for that element.

• It even overrides the inline styles from the markup.

• The only way to override is by using another !important rule, declared either with higher CSS specificity in the CSS, or equal CSS specificity later in the code.

• Must Read - CSS Specificity by MDN

Principled Design of the Modern Web Architecture by Roy T. Fielding and Richard N. Taylor, i.e. sequence of works from all REST terminology came from, contains definition of client-server interaction:

All REST interactions are stateless. That is, each request contains all of the information necessary for a connector to understand the request, independent of any requests that may have preceded it.

This restriction accomplishes four functions, 1st and 3rd are important in this particular case:

• 1st: it removes any need for the connectors to retain application state between requests, thus reducing consumption of physical resources and improving scalability;
• 3rd: it allows an intermediary to view and understand a request in isolation, which may be necessary when services are dynamically rearranged;

And now lets go back to your security case. Every single request should contains all required information, and authorization/authentication is not an exception. How to achieve this? Literally send all required information over wires with every request.

One of examples how to archeive this is hash-based message authentication code or HMAC. In practice this means adding a hash code of current message to every request. Hash code calculated by cryptographic hash function in combination with a secret cryptographic key. Cryptographic hash function is either predefined or part of code-on-demand REST conception (for example JavaScript). Secret cryptographic key should be provided by server to client as resource, and client uses it to calculate hash code for every request.

There are a lot of examples of HMAC implementations, but I'd like you to pay attention to the following three:

• Authenticating REST Requests for Amazon Simple Storage Service (Amazon S3)
• Answer by Mauriceless on quiestion: "How to implement HMAC Authentication in a RESTful WCF API"
• crypto-js: JavaScript implementations of standard and secure cryptographic algorithms

How it works in practice

If client knows the secret key, then it's ready to operate with resources. Otherwise he will be temporarily redirected (status code 307 Temporary Redirect) to authorize and to get secret key, and then redirected back to the original resource. In this case there is no need to know beforehand (i.e. hardcode somewhere) what the URL to authorize the client is, and it possible to adjust this schema with time.

Hope this will helps you to find the proper solution!

If you want to reuse CSS and JavaScript from the main page maybe you should consider replacing <IFRAME> with a Ajax loaded content. This is more SEO friendly now when search bots are able to execute JavaScript.

This is jQuery example that includes another html page into your document. This is much more SEO friendly than iframe. In order to be sure that the bots are not indexing the included page just add it to disallow in robots.txt

<html>
  <header>
    <script src="/js/jquery.js" type="text/javascript"></script>
  </header>
  <body>
    <div id='include-from-outside'></div>
    <script type='text/javascript'>
      $('#include-from-outside').load('http://example.com/included.html');
    </script> 
  </body>
</html>

You could also include jQuery directly from Google: http://code.google.com/apis/ajaxlibs/documentation/ - this means optional auto-inclusion of newer versions and some significant speed increase. Also, means that you have to trust them for delivering you just the jQuery ;)

I wanted to do the same, and I had first problems with the split function, then problems with installing pandas 0.15.2, so I went back to my old version, and wrote a little function that works very well. I hope this can help!

# input - df: a Dataframe, chunkSize: the chunk size
# output - a list of DataFrame
# purpose - splits the DataFrame into smaller chunks
def split_dataframe(df, chunk_size = 10000): 
    chunks = list()
    num_chunks = len(df) // chunk_size + 1
    for i in range(num_chunks):
        chunks.append(df[i*chunk_size:(i+1)*chunk_size])
    return chunks

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

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

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

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

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

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

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

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

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

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

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

If you use TortoiseGit (it provides GUI for Git), you can right click your Git repo folder then click Git Sync.

You can select your branches to compare if not selected. Than you can view differences commit. You can also right click any commit then Compare with previous revision to view differences side by side.

Prior to Java 6, there is no support of file permission update at Java level. You have to implement your own native method or call Runtime.exec() to execute OS level command such as chmod.

Starting from Java 6, you can useFile.setReadable()/File.setWritable()/File.setExecutable() to set file permissions. But it doesn't simulate the POSIX file system which allows to set permission for different users. File.setXXX() only allows to set permission for owner and everyone else.

Starting from Java 7, POSIX file permission is introduced. You can set file permissions like what you have done on *nix systems. The syntax is :

File file = new File("file4.txt");
file.createNewFile();

Set<PosixFilePermission> perms = new HashSet<>();
perms.add(PosixFilePermission.OWNER_READ);
perms.add(PosixFilePermission.OWNER_WRITE);

Files.setPosixFilePermissions(file.toPath(), perms);

This method can only be used on POSIX file system, this means you cannot call it on Windows system.

For details on file permission management, recommend you to read this post.

An application bundle (a .app file) is actually a bunch of directories. Instead of using open and the .app name, you can actually move in to it and start the actual binary. For instance:

$ cd /Applications/LittleSnapper.app/
$ ls
Contents
$ cd Contents/MacOS/
$ ./LittleSnapper

That is the actual binary that might accept arguments (or not, in LittleSnapper's case).

Because like many have said here, references are not objects. they are simply aliases. True some compilers might implement them as pointers, but the standard does not force/specify that. And because references are not objects, you cannot point to them. Storing elements in an array means there is some kind of index address (i.e., pointing to elements at a certain index); and that is why you cannot have arrays of references, because you cannot point to them.

Use boost::reference_wrapper, or boost::tuple instead; or just pointers.

I spend several hours with this issue... :( Getters and setters are REQUIRED in POST parameters object declaration. I do not recommend using simple data objects (string,int, ...) as they require special request format.

[HttpPost]
public HttpResponseMessage PostProcedure(EdiconLogFilter filter){

}

Does not work when:

public class EdiconLogFilter
{
    public string fClientName;
    public string fUserName;
    public string fMinutes;
    public string fLogDate;
}

Works fine when:

public class EdiconLogFilter
{
    public string fClientName { get; set; }
    public string fUserName { get; set; }
    public string fMinutes { get; set; }
    public string fLogDate { get; set; }
}

I know it's been a while this has been posted, but with iOS 7.1, a few things have changed.

So far, if you are developing an App, you MUST have a valid SSL certificate recognized by Apple, otherwise you will get an error message on you iDevice. No more self-signed certificates. See here a list:

http://support.apple.com/kb/ht5012

Additionally, if you are here, it means that you are trying to make you iDevice resolve a name (to your https server), on a test or development environment.

Instead of using squid, which is a great application, you could simply run a very basic DNS server like dnsmasq. It will use your hosts file as a first line of name resolution, so, you can basically fool your iDevice there, saying that www.blah.com is 192.168.10.10.

The configuration file is as simple as 3 to 4 lines, and you can even configure its internal DHCP server if you want.

Here is mine:

listen-address=192.168.10.35

domain-needed

bogus-priv

no-dhcp-interface=eth0

local=/localnet/

Of course you have to configure networking on your iDevice to use that DNS (192.168.10.35 in my case), or just start using DHCP from that server anyway, after properly configured.

Additionally, if dnsmasq cannot resolve the name internally, it uses your regular DNS server (like 8.8.8.8) to resolve it for you. VERY simple, elegant, and solved my problems with iDevice App installation in-house.

By the way, solves many name resolution problems with regular macs (OS X) as well.

Now, my rant: bloody Apple. Making a device safe should not include castrating the operating system or the developers.

Your belief about what will happen is not correct. Setting a default value for a column will not affect the existing data in the table.

I create a table with a column col2 that has no default value

SQL> create table foo(
  2    col1 number primary key,
  3    col2 varchar2(10)
  4  );

Table created.

SQL> insert into foo( col1 ) values (1);

1 row created.

SQL> insert into foo( col1 ) values (2);

1 row created.

SQL> insert into foo( col1 ) values (3);

1 row created.

SQL> select * from foo;

      COL1 COL2
---------- ----------
         1
         2
         3

If I then alter the table to set a default value, nothing about the existing rows will change

SQL> alter table foo
  2    modify( col2 varchar2(10) default 'foo' );

Table altered.

SQL> select * from foo;

      COL1 COL2
---------- ----------
         1
         2
         3

SQL> insert into foo( col1 ) values (4);

1 row created.

SQL> select * from foo;

      COL1 COL2
---------- ----------
         1
         2
         3
         4 foo

Even if I subsequently change the default again, there will still be no change to the existing rows

SQL> alter table foo
  2    modify( col2 varchar2(10) default 'bar' );

Table altered.

SQL> select * from foo;

      COL1 COL2
---------- ----------
         1
         2
         3
         4 foo

SQL> insert into foo( col1 ) values (5);

1 row created.

SQL> select * from foo;

      COL1 COL2
---------- ----------
         1
         2
         3
         4 foo
         5 bar

This works for me:

filename = "foo"
text = File.read(filename) 
content = text.gsub(/search_regexp/, "replacestring")
File.open(filename, "w") { |file| file << content }

You Should choose the first one. They have no difference except the performance the first one will be the fast in the comparison of second one.

If the variable inside the double quote PHP take time to parse variable.

Check out this Single quotes or double quotes for variable concatenation?

This is another example Is there a performance benefit single quote vs double quote in php?

I did not understand why this answer in above link get upvoted and why this answer got downvote.

As I said same thing.

You can look at here as well

What is faster in PHP, single or double quotes?

Step 1 is always to first determine where the problem lies. Your title and most of your question seem to suggest that you're running into quite a low length limit on the length of a string in JavaScript / on browsers, an improbably low limit. You're not. Consider:

var str;

document.getElementById('theButton').onclick = function() {
  var build, counter;

  if (!str) {
    str = "0123456789";
    build = [];
    for (counter = 0; counter < 900; ++counter) {
      build.push(str);
    }
    str = build.join("");
  }
  else {
    str += str;
  }
  display("str.length = " + str.length);
};

Live copy

Repeatedly clicking the relevant button keeps making the string longer. With Chrome, Firefox, Opera, Safari, and IE, I've had no trouble with strings more than a million characters long:

str.length = 9000
str.length = 18000
str.length = 36000
str.length = 72000
str.length = 144000
str.length = 288000
str.length = 576000
str.length = 1152000
str.length = 2304000
str.length = 4608000
str.length = 9216000
str.length = 18432000

...and I'm quite sure I could got a lot higher than that.

So it's nothing to do with a length limit in JavaScript. You haven't show your code for sending the data to the server, but most likely you're using GET which means you're running into the length limit of a GET request, because GET parameters are put in the query string. Details here.

You need to switch to using POST instead. In a POST request, the data is in the body of the request rather than in the URL, and can be very, very large indeed.

You need only to write:

GRANT DBA TO NewDBA;

Because this already makes the user a DB Administrator

scroll.fullScroll(View.FOCUS_DOWN) will lead to the change of focus. That will bring some strange behavior when there are more than one focusable views, e.g two EditText. There is another way for this question.

    View lastChild = scrollLayout.getChildAt(scrollLayout.getChildCount() - 1);
    int bottom = lastChild.getBottom() + scrollLayout.getPaddingBottom();
    int sy = scrollLayout.getScrollY();
    int sh = scrollLayout.getHeight();
    int delta = bottom - (sy + sh);

    scrollLayout.smoothScrollBy(0, delta);

This works well.

Kotlin Extension

fun ScrollView.scrollToBottom() {
    val lastChild = getChildAt(childCount - 1)
    val bottom = lastChild.bottom + paddingBottom
    val delta = bottom - (scrollY+ height)        
    smoothScrollBy(0, delta)
}

You shall perform different detections of iPhone X depending on the actual need.

for dealing with the top notch (statusbar, navbar), etc.

class var hasTopNotch: Bool {
    if #available(iOS 11.0, tvOS 11.0, *) {
        // with notch: 44.0 on iPhone X, XS, XS Max, XR.
        // without notch: 24.0 on iPad Pro 12.9" 3rd generation, 20.0 on iPhone 8 on iOS 12+.
        return UIApplication.shared.delegate?.window??.safeAreaInsets.top ?? 0 > 24
    }
    return false
}

for dealing with the bottom home indicator (tabbar), etc.

class var hasBottomSafeAreaInsets: Bool {
    if #available(iOS 11.0, tvOS 11.0, *) {
        // with home indicator: 34.0 on iPhone X, XS, XS Max, XR.
        // with home indicator: 20.0 on iPad Pro 12.9" 3rd generation.
        return UIApplication.shared.delegate?.window??.safeAreaInsets.bottom ?? 0 > 0
    }
    return false
}

for backgrounds size, fullscreen features, etc.

class var isIphoneXOrBigger: Bool {
    // 812.0 on iPhone X, XS.
    // 896.0 on iPhone XS Max, XR.
    return UIScreen.main.bounds.height >= 812
}

Note: eventually mix it with UIDevice.current.userInterfaceIdiom == .phone
Note: this method requires to have a LaunchScreen storyboard or proper LaunchImages

for backgrounds ratio, scrolling features, etc.

class var isIphoneXOrLonger: Bool {
    // 812.0 / 375.0 on iPhone X, XS.
    // 896.0 / 414.0 on iPhone XS Max, XR.
    return UIScreen.main.bounds.height / UIScreen.main.bounds.width >= 896.0 / 414.0
}

Note: this method requires to have a LaunchScreen storyboard or proper LaunchImages

for analytics, stats, tracking, etc.

Get the machine identifier and compare it to documented values:

class var isIphoneX: Bool {
    var size = 0
    sysctlbyname("hw.machine", nil, &size, nil, 0)
    var machine = [CChar](repeating: 0, count: size)
    sysctlbyname("hw.machine", &machine, &size, nil, 0)
    let model = String(cString: machine)
    return model == "iPhone10,3" || model == "iPhone10,6"
}

To include the simulator as a valid iPhone X in your analytics:

class var isIphoneX: Bool {
    let model: String
    if TARGET_OS_SIMULATOR != 0 {
        model = ProcessInfo.processInfo.environment["SIMULATOR_MODEL_IDENTIFIER"] ?? ""
    } else {
        var size = 0
        sysctlbyname("hw.machine", nil, &size, nil, 0)
        var machine = [CChar](repeating: 0, count: size)
        sysctlbyname("hw.machine", &machine, &size, nil, 0)
        model = String(cString: machine)
    }
    return model == "iPhone10,3" || model == "iPhone10,6"
}

To include iPhone XS, XS Max and XR, simply look for models starting with "iPhone11,":

return model == "iPhone10,3" || model == "iPhone10,6" || model.starts(with: "iPhone11,")

for faceID support

import LocalAuthentication
/// will fail if user denies canEvaluatePolicy(_:error:)
class var canUseFaceID: Bool {
    if #available(iOS 11.0, *) {
        return LAContext().biometryType == .typeFaceID
    }
    return false
}

It looks like a container with the name qgis-desktop-2-4 already exists in the system. You can check the output of the below command to confirm if it indeed exists:

$ docker ps -a

The last column in the above command's output is for names.

If the container exists, remove it using:

$ docker rm qgis-desktop-2-4

Or forcefully using,

$ docker rm -f qgis-desktop-2-4

And then try creating a new container.

You may want to try out simple function I posted on another thread related to reading date value from excel sheet.

It simply takes text from the cell as input and gives DateTime as output.

I would be happy to see improvement in my sample code provided for benefit of the .Net development community.

Here is the link for the thread C# not reading excel date from spreadsheet

For me this worked:

buildscript {
    repositories {
        maven { url "http://jcenter.bintray.com"}
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
...
}

allprojects {
    repositories {
        mavenCentral()
        jcenter{ url "http://jcenter.bintray.com/" }
        maven {

            name 'Google'
        }
    }
}

A MIME type is a label used to identify a type of data. It is used so software can know how to handle the data. It serves the same purpose on the Internet that file extensions do on Microsoft Windows.

So if a server says "This is text/html" the client can go "Ah, this is an HTML document, I can render that internally", while if the server says "This is application/pdf" the client can go "Ah, I need to launch the FoxIt PDF Reader plugin that the user has installed and that has registered itself as the application/pdf handler."

You'll most commonly find them in the headers of HTTP messages (to describe the content that an HTTP server is responding with or the formatting of the data that is being POSTed in a request) and in email headers (to describe the message format and attachments).

This is what the res.locals object is for. Setting variables directly on the request object is not supported or documented. res.locals is guaranteed to hold state over the life of a request.

res.locals

An object that contains response local variables scoped to the request, and therefore available only to the view(s) rendered during that request / response cycle (if any). Otherwise, this property is identical to app.locals.

This property is useful for exposing request-level information such as the request path name, authenticated user, user settings, and so on.

app.use(function(req, res, next) {
    res.locals.user = req.user;  
    res.locals.authenticated = !req.user.anonymous;
    next();
});

To retrieve the variable in the next middleware:

app.use(function(req, res, next) {
    if (res.locals.authenticated) {
        console.log(res.locals.user.id);
    }
    next();
});

I ran into similar problem a while back and what was happening in my case was the outer recycler view was working perfectly fine but the the adapter of inner/second recycler view had minor issues all the methods like constructor got initiated and even getCount() method was being called, although the final methods responsible to generate view ie..

1. onBindViewHolder() methods never got called. --> Problem 1.

2. When it got called finally it never show the list items/rows of recycler view. --> Problem 2.

Reason why this happened :: When you put a recycler view inside another recycler view, then height of the first/outer recycler view is not auto adjusted. It is defined when the first/outer view is created and then it remains fixed. At that point your second/inner recycler view has not yet loaded its items and thus its height is set as zero and never changes even when it gets data. Then when onBindViewHolder() in your second/inner recycler view is called, it gets items but it doesn't have the space to show them because its height is still zero. So the items in the second recycler view are never shown even when the onBindViewHolder() has added them to it.

Solution :: you have to create your custom LinearLayoutManager for the second recycler view and that is it. To create your own LinearLayoutManager: Create a Java class with the name CustomLinearLayoutManager and paste the code below into it. NO CHANGES REQUIRED

public class CustomLinearLayoutManager extends LinearLayoutManager {

    private static final String TAG = CustomLinearLayoutManager.class.getSimpleName();

    public CustomLinearLayoutManager(Context context) {
        super(context);

    }

    public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
        super(context, orientation, reverseLayout);
    }

                if (i == 0) {

                int childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec,

                measuredDimension[0] = view.getMeasuredWidth() + p.leftMargin + p.rightMargin;
                measuredDimension[1] = view.getMeasuredHeight() + p.bottomMargin + p.topMargin;
                recycler.recycleView(view);

I had this problem for quite a while, and like everybody else the answers above didn't apply to my project.

In my project I had linked up a project to my project and it was throwing ClassDefNotFoundError every time some code for the other project was executed.

So this was my solution. I went to project properties of my project and Java Build Path. Pressed the "Source"-tab and "link source" from src-folder of the other project to my own project and named a new folder "core-src".

Hopes this solution helps someone

<build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.6.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

Another way would be creating a mutable integer:

class MutableInt {
  int value = 0;
  public void inc () { ++value; }
  public int get () { return value; }
}
...
Map<String,MutableInt> map = new HashMap<String,MutableInt> ();
MutableInt value = map.get (key);
if (value == null) {
  value = new MutableInt ();
  map.put (key, value);
} else {
  value.inc ();
}

of course this implies creating an additional object but the overhead in comparison to creating an Integer (even with Integer.valueOf) should not be so much.

I agree with Ajeesh, but there are simpler ways to do this...

if ($maker == "2") { }

or

if ($maker == 2) { }

• Why am I not returning a "Toyota" value? Because the "Toyota" choice in the Selection Box would have already returned "2", which, would indicate that the selected Manufacturer in the Selection Box would be Toyota.

• How would the user know if the value is equal to the Toyota selection in the Selection Box? In between my example code's brackets, you would put $maker = "Toyota" then echo $maker, or create a new string, like so: $maketwo = "Toyota" then you can echo $makertwo (I much prefer creating a new string, rather than overwriting $maker's original value.)

• If the user selects "Nissan", will the example code take care of that as well..? Yes, and no. While "Toyota" would return value "2", "Nissan" would instead return value "3". The current set value that the example code is looking for is "2", which means that if the user selects "Nissan", which represents value "3", then presses "Search", the example code would not be executed. You can easily change the code to check for value "3", or value "1", which represents "--Any--".

• What if the user clicks "Search" while the Selection Box is set to "Select Manufacturer"? How can I prevent them from doing so? To prevent them from proceeding any further, change the set value of the example code to "0", and in between the brackets, you may place your code, then after that, add return;, which terminates all execution of any further code within the function / statement.

Why not use them in the Users directory in the .bash_profile file, so you don't have to push any files with your variables to production?

The top answer here seems to be an OS dependent answer; for a more portable solution you can write up a quick sleep function using the ctime header file (although this may be a poor implementation on my part).

#include <iostream>
#include <ctime>

using namespace std;

void sleep(float seconds){
    clock_t startClock = clock();
    float secondsAhead = seconds * CLOCKS_PER_SEC;
    // do nothing until the elapsed time has passed.
    while(clock() < startClock+secondsAhead);
    return;
}
int main(){

    cout << "Next string coming up in one second!" << endl;
    sleep(1.0);
    cout << "Hey, what did I miss?" << endl;

    return 0;
}

You can use bash arrays

$ str_array=("continuation"
             "lines")

then

$ echo "${str_array[*]}"
continuation lines

there is an extra space, because (after bash manual):

If the word is double-quoted, ${name[*]} expands to a single word with the value of each array member separated by the first character of the IFS variable

So set IFS='' to get rid of extra space

$ IFS=''
$ echo "${str_array[*]}"
continuationlines

just use "..option hidden selected.." as default option

For pointers in C, we have

a[5] == *(a + 5)

and also

5[a] == *(5 + a)

Hence it is true that a[5] == 5[a].

I solved my problem like this...

The Problem to push mostly is because of the size of the files that need to be pushed. I was trying to push some libraries of just size 2 mb, then too the push was giving error of RPC with result 7. The line is of 4 mbps and is working fine. Some subsequent tries to the push got me success. If such error comes, wait for few minutes and keep on trying.

I also found out that there are some RPC failures if the github is down or is getting unstable network at their side.

So keeping up trying after some intervals is the only option!

Use the pull request builder plugin: https://wiki.jenkins-ci.org/display/JENKINS/GitHub+pull+request+builder+plugin

It's really straightforward. You can then setup GitHub webhooks to trigger builds.

Follow the instructions in this Answer to format the EditText mask.

https://stackoverflow.com/a/34907607/1013929

And after that, you can catch the original numbers from the masked string with:

String phoneNumbers = maskedString.replaceAll("[^\\d]", "");

A repeater inside a repeater

<div ng-repeat="step in steps">
    <div ng-repeat="(key, value) in step">
        {{key}} : {{value}}
    </div>

So the problem is that you want to upload a base 64 image and you have a blob url. Now the answer that will work on all html 5 browsers is: Do:

  var fileInput = document.getElementById('myFileInputTag');
  var preview = document.getElementById('myImgTag');

  fileInput.addEventListener('change', function (e) {
      var url = URL.createObjectURL(e.target.files[0]);
      preview.setAttribute('src', url);
  });
function Upload()
{
     // preview can be image object or image element
     var myCanvas = document.getElementById('MyCanvas');
     var ctx = myCanvas.getContext('2d');
     ctx.drawImage(preview, 0,0);
     var base64Str = myCanvas.toDataURL();
     $.ajax({
         url: '/PathToServer',
         method: 'POST',
         data: {
             imageString: base64Str
         },
     success: function(data) { if(data && data.Success) {}},
     error: function(a,b,c){alert(c);}
     });
 }

Usually when a method accepts a file, there's another method nearby that accepts a stream. If this isn't the case, the API is badly coded. Otherwise, you can use temporary files, where permission is usually granted in many cases. If it's applet, you can request write permission.

An example:

try {
    // Create temp file.
    File temp = File.createTempFile("pattern", ".suffix");

    // Delete temp file when program exits.
    temp.deleteOnExit();

    // Write to temp file
    BufferedWriter out = new BufferedWriter(new FileWriter(temp));
    out.write("aString");
    out.close();
} catch (IOException e) {
}

I think you simply have a double conversion of the character type there :D

It may be, because you opened an html document within a html document. So you have something that looks like this in the end

<!DOCTYPE html> 
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title></title>
</head>
<body>
<!DOCTYPE html> 
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Test</title>.......

The use of mb_detect_encoding therefore may lead you to other issues.

For MYSQL

ALTER TABLE myTable MODIFY myColumn {DataType} NULL

If you are planning on doing any kind of inheritance, then I would recommend this.constructor. This simple example should illustrate why:

class ConstructorSuper {
  constructor(n){
    this.n = n;
  }

  static print(n){
    console.log(this.name, n);
  }

  callPrint(){
    this.constructor.print(this.n);
  }
}

class ConstructorSub extends ConstructorSuper {
  constructor(n){
    this.n = n;
  }
}

let test1 = new ConstructorSuper("Hello ConstructorSuper!");
console.log(test1.callPrint());

let test2 = new ConstructorSub("Hello ConstructorSub!");
console.log(test2.callPrint());

• test1.callPrint() will log ConstructorSuper Hello ConstructorSuper! to the console
• test2.callPrint() will log ConstructorSub Hello ConstructorSub! to the console

The named class will not deal with inheritance nicely unless you explicitly redefine every function that makes a reference to the named Class. Here is an example:

class NamedSuper {
  constructor(n){
    this.n = n;
  }

  static print(n){
    console.log(NamedSuper.name, n);
  }

  callPrint(){
    NamedSuper.print(this.n);
  }
}

class NamedSub extends NamedSuper {
  constructor(n){
    this.n = n;
  }
}

let test3 = new NamedSuper("Hello NamedSuper!");
console.log(test3.callPrint());

let test4 = new NamedSub("Hello NamedSub!");
console.log(test4.callPrint());

• test3.callPrint() will log NamedSuper Hello NamedSuper! to the console
• test4.callPrint() will log NamedSuper Hello NamedSub! to the console

See all the above running in Babel REPL.

You can see from this that test4 still thinks it's in the super class; in this example it might not seem like a huge deal, but if you are trying to reference member functions that have been overridden or new member variables, you'll find yourself in trouble.

On Rails, one can do the following using the rails console:

connection = ActiveRecord::Base.connection
connection.execute("SET FOREIGN_KEY_CHECKS=0;")

Before get permission you can check api version,

  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M)
  {
      if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {

      } 
      else
      {
         ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, 401);
      }
  }
  else
  {
    // if version is below m then write code here,          
  }

Get the Result of the permission dialog,

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == 401) {
        if (grantResults.length == 0 || grantResults == null) {

        } else if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            openGallery();
        } else if (grantResults[0] == PackageManager.PERMISSION_DENIED) {
        }
    } else if (requestCode == 402) {
        if (grantResults.length == 0 || grantResults == null) {

        } else if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {

        } else if (grantResults[0] == PackageManager.PERMISSION_DENIED) {
        }
    }
} 

Installing ASP.NET MVC3 from here should help.

In XCode 4.0 main workspace, at the top left side & just after the "Stop Button", there is scheme selector, click on it and change your scheme to IPhone Simulator. That's it

if you are using extracted tomcat then,

startup.sh and shutdown.sh are two script located in TOMCAT/bin/ to start and shutdown tomcat, You could use that

if tomcat is installed then

/etc/init.d/tomcat5.5 start
/etc/init.d/tomcat5.5 stop
/etc/init.d/tomcat5.5 restart

Suggested changes:

• Do not invoke the Command object's Execute method;
• Set the Recordset object's Source property to be your Command object;
• Invoke the Recordset object's Open method with no parameters;
• Remove the parentheses from around the Recordset object in the call to CopyFromRecordset;
• Actually declare your variables :)

Revised code:

Sub GetDataFromADO()

    'Declare variables'
        Dim objMyConn As ADODB.Connection
        Dim objMyCmd As ADODB.Command
        Dim objMyRecordset As ADODB.Recordset

        Set objMyConn = New ADODB.Connection
        Set objMyCmd = New ADODB.Command
        Set objMyRecordset = New ADODB.Recordset

    'Open Connection'
        objMyConn.ConnectionString = "Provider=SQLOLEDB;Data Source=localhost;User ID=abc;Password=abc;"    
        objMyConn.Open

    'Set and Excecute SQL Command'
        Set objMyCmd.ActiveConnection = objMyConn
        objMyCmd.CommandText = "select * from mytable"
        objMyCmd.CommandType = adCmdText

    'Open Recordset'
        Set objMyRecordset.Source = objMyCmd
        objMyRecordset.Open

    'Copy Data to Excel'
        ActiveSheet.Range("A1").CopyFromRecordset objMyRecordset

End Sub

This is possible by 'cheating' with a block helper. This probably goes against the Ideology of the people who developed Handlebars.

Handlebars.registerHelper('ifCond', function(v1, v2, options) {
  if(v1 === v2) {
    return options.fn(this);
  }
  return options.inverse(this);
});

You can then call the helper in the template like this

{{#ifCond v1 v2}}
    {{v1}} is equal to {{v2}}
{{else}}
    {{v1}} is not equal to {{v2}}
{{/ifCond}}
