Your question has already been answered, but IIRC you can replace lines like:

if d.has_key(scope_item):

with:

if scope_item in d:

That is, d references d.keys() in that construction. Sometimes defaultdict isn't the best option (for example, if you want to execute multiple lines of code after the else associated with the above if), and I find the in syntax easier to read.

In Oracle the location that contains information about all database objects including tables and stored procedures is called the Data Dictionary. It is a collection of views that provides you with access to the metadata that defines the database. You can query the Data Dictionary views for a list of desired database objects and then use the functions available in dbms_metadata package to get the DDL for each object. Alternative is to investigate the support in dbms_metadata to export DDLs for a collection of objects.

For a few pointers, for example to get a list of tables you can use the following Data Dictionary views

• user_tables contains all tables owned by the user
• all_tables contains all tables that are accessible by the user
• and so on...

Nope, you've heard of MonoTouch which is a .NET/mono environment for iPhone development. But you still need a Mac and the official iPhone SDK. And the emulator is the official apple one, this acts as a separate IDE and allows you to not have to code in Objective C, rather you code in c#

It's an interesting project to say the least....

EDIT: apparently, you can distribute on the app store now, early on that was a no go....

The package.json file is used by npm to learn about your node.js project.

Use npm init to generate package.json files for you!

It comes bundled with npm. Read its documentation here: https://docs.npmjs.com/cli/init

Also, there's an official tool you can use to generate this file programmatically: https://github.com/npm/init-package-json

I was facing the same issue. After many tries below solution worked for me.

Before installing VC++ install your windows updates. 1. Go to Start - Control Panel - Windows Update 2. Check for the updates. 3. Install all updates. 4. Restart your system.

After that you can follow the below steps.

Have a look at Hashtables, Hashmaps, HashSets and so forth. They all store the hashed key as their keys. When invoking get(Object key) the hash of the parameter is generated and lookup in the given hashes.

When not overwriting hashCode() and the instance of the key has been changed (for example a simple string that doesn't matter at all), the hashCode() could result in 2 different hashcodes for the same object, resulting in not finding your given key in map.get().

Encapsulation is basically denying the access to the internal implementation or knowledge about internals to the external world, while Abstraction is giving a generalized view of any implementation that helps the external world to interact with it

At the first glance, I missed, that my "web" service didn't actually start, so that's why nginx couldn't find any host

web_1    | python3: can't open file '/var/www/app/app/app.py': [Errno 2] No such file or directory
web_1 exited with code 2
nginx_1  | [emerg] 1#1: host not found in upstream "web:4044" in /etc/nginx/conf.d/nginx.conf:2

The bold property of the font itself is read only, but the actual font property of the text box is not. You can change the font of the textbox to bold as follows:

  textBox1.Font = new Font(textBox1.Font, FontStyle.Bold);

And then back again:

  textBox1.Font = new Font(textBox1.Font, FontStyle.Regular);

To just get a date you can cast it

cast(user.registration as date)

and to get a specific format use date_format

date_format(registration, '%Y-%m-%d')

What is a virtual destructor or how to use virtual destructor

A class destructor is a function with same name of the class preceding with ~ that will reallocate the memory that is allocated by the class. Why we need a virtual destructor

See the following sample with some virtual functions

The sample also tell how you can convert a letter to upper or lower

#include "stdafx.h"
#include<iostream>
using namespace std;
// program to convert the lower to upper orlower
class convertch
{
public:
  //void convertch(){};
  virtual char* convertChar() = 0;
  ~convertch(){};
};

class MakeLower :public convertch
{
public:
  MakeLower(char *passLetter)
  {
    tolower = true;
    Letter = new char[30];
    strcpy(Letter, passLetter);
  }

  virtual ~MakeLower()
  {
    cout<< "called ~MakeLower()"<<"\n";
    delete[] Letter;
  }

  char* convertChar()
  {
    size_t len = strlen(Letter);
    for(int i= 0;i<len;i++)
      Letter[i] = Letter[i] + 32;
    return Letter;
  }

private:
  char *Letter;
  bool tolower;
};

class MakeUpper : public convertch
{
public:
  MakeUpper(char *passLetter)
  {
    Letter = new char[30];
    toupper = true;
    strcpy(Letter, passLetter);
  }

  char* convertChar()
  {   
    size_t len = strlen(Letter);
    for(int i= 0;i<len;i++)
      Letter[i] = Letter[i] - 32;
    return Letter;
  }

  virtual ~MakeUpper()
  {
    cout<< "called ~MakeUpper()"<<"\n";
    delete Letter;
  }

private:
  char *Letter;
  bool toupper;
};


int _tmain(int argc, _TCHAR* argv[])
{
  convertch *makeupper = new MakeUpper("hai"); 
  cout<< "Eneterd : hai = " <<makeupper->convertChar()<<" ";     
  delete makeupper;
  convertch *makelower = new MakeLower("HAI");;
  cout<<"Eneterd : HAI = " <<makelower->convertChar()<<" "; 
  delete makelower;
  return 0;
}

From the above sample you can see that the destructor for both MakeUpper and MakeLower class is not called.

See the next sample with the virtual destructor

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

using namespace std;
// program to convert the lower to upper orlower
class convertch
{
public:
//void convertch(){};
virtual char* convertChar() = 0;
virtual ~convertch(){}; // defined the virtual destructor

};
class MakeLower :public convertch
{
public:
MakeLower(char *passLetter)
{
tolower = true;
Letter = new char[30];
strcpy(Letter, passLetter);
}
virtual ~MakeLower()
{
cout<< "called ~MakeLower()"<<"\n";
      delete[] Letter;
}
char* convertChar()
{
size_t len = strlen(Letter);
for(int i= 0;i<len;i++)
{
Letter[i] = Letter[i] + 32;

}

return Letter;
}

private:
char *Letter;
bool tolower;

};
class MakeUpper : public convertch
{
public:
MakeUpper(char *passLetter)
{
Letter = new char[30];
toupper = true;
strcpy(Letter, passLetter);
}
char* convertChar()
{

size_t len = strlen(Letter);
for(int i= 0;i<len;i++)
{
Letter[i] = Letter[i] - 32;
}
return Letter;
}
virtual ~MakeUpper()
{
      cout<< "called ~MakeUpper()"<<"\n";
delete Letter;
}
private:
char *Letter;
bool toupper;
};


int _tmain(int argc, _TCHAR* argv[])
{

convertch *makeupper = new MakeUpper("hai");

cout<< "Eneterd : hai = " <<makeupper->convertChar()<<" \n";

delete makeupper;
convertch *makelower = new MakeLower("HAI");;
cout<<"Eneterd : HAI = " <<makelower->convertChar()<<"\n ";


delete makelower;
return 0;
}

The virtual destructor will call explicitly the most derived run time destructor of class so that it will be able to clear the object in a proper way.

The easiest way i found to solve that problem was to select a label and then send:

label.sendKeys(Keys.PAGE_DOWN);

Hope it works!

The technical limitations with using PUT and DELETE requests does not lie with PHP or Apache2; it is instead on the burden of the browser to sent those types of requests.

Simply putting <form action="" method="PUT"> will not work because there are no browsers that support that method (and they would simply default to GET, treating PUT the same as it would treat gibberish like FDSFGS). Sadly those HTTP verbs are limited to the realm of non-desktop application browsers (ie: web service consumers).

from within the vscode terminal,

git remote set-url origin https://<your github username>:<your password>@github.com/<your github username>/<your github repository name>.git

for the quickest, but not so encouraged way.

Use curly brackets and put all the attributes you want to add inside

Example:

$('#objId').attr({
    target: 'nw',
    title: 'Opens in a new window'
});

In addition to what Allan did, adding missing classes, I followed @emdog4's solution and added the Core Data library by going to Build Phases in Xcode and under the 'Link Binary with Libraries' clicking on the + and selecting the 'CoreData.framework'. This sorted out my error

You need to add the package containing the executable pg_config.

Personally I don't find the standard diagramming technique very helpful - the arrows always seem to point the wrong way for me. (They generally point towards the "parent" of each commit, which ends up being backwards in time, which is weird).

To explain it in words:

• When you rebase your branch onto their branch, you tell Git to make it look as though you checked out their branch cleanly, then did all your work starting from there. That makes a clean, conceptually simple package of changes that someone can review. You can repeat this process again when there are new changes on their branch, and you will always end up with a clean set of changes "on the tip" of their branch.
• When you merge their branch into your branch, you tie the two branch histories together at this point. If you do this again later with more changes, you begin to create an interleaved thread of histories: some of their changes, some of my changes, some of their changes. Some people find this messy or undesirable.

For reasons I don't understand, GUI tools for Git have never made much of an effort to present merge histories more cleanly, abstracting out the individual merges. So if you want a "clean history", you need to use rebase.

I seem to recall having read blog posts from programmers who only use rebase and others that never use rebase.

Example

I'll try explaining this with a just-words example. Let's say other people on your project are working on the user interface, and you're writing documentation. Without rebase, your history might look something like:

Write tutorial
Merge remote-tracking branch 'origin/master' into fixdocs
Bigger buttons
Drop down list
Extend README
Merge remote-tracking branch 'origin/master' into fixdocs
Make window larger
Fix a mistake in howto.md

That is, merges and UI commits in the middle of your documentation commits.

If you rebased your code onto master instead of merging it, it would look like this:

Write tutorial
Extend README
Fix a mistake in howto.md
Bigger buttons
Drop down list
Make window larger

All of your commits are at the top (newest), followed by the rest of the master branch.

(Disclaimer: I'm the author of the "10 things I hate about Git" post referred to in another answer)

FileStream fs = new FileStream(txtSourcePath.Text,FileMode.Open, FileAccess.Read);
using(StreamReader sr = new StreamReader(fs))
{
   using (StreamWriter sw = new StreamWriter(Destination))
   {
            sw.writeline("Your text");
    }
}

You need to read up about the Camera. (I think to do what you want, you'd have to save the current image to your app, do the select/delete there, and then recall the camera to try again, rather than doing the retry directly inside the camera.)

if you want to get the variables of sections you can pay like this:

$_view      = new \View;
$_sections  = $_view->getFacadeRoot()->getSections();
dd($_sections);
/*
Out:
array:1 [?
  "title" => "Painel"
]
*/

Here's another example using the StatusBar as a progress bar.

By using some Unicode Characters, you can mimic a progress bar. 9608 - 9615 are the codes I tried for the bars. Just select one according to how much space you want to show between the bars. You can set the length of the bar by changing NUM_BARS. Also by using a class, you can set it up to handle initializing and releasing the StatusBar automatically. Once the object goes out of scope it will automatically clean up and release the StatusBar back to Excel.

' Class Module - ProgressBar
Option Explicit

Private statusBarState As Boolean
Private enableEventsState As Boolean
Private screenUpdatingState As Boolean
Private Const NUM_BARS As Integer = 50
Private Const MAX_LENGTH As Integer = 255
Private BAR_CHAR As String
Private SPACE_CHAR As String

Private Sub Class_Initialize()
    ' Save the state of the variables to change
    statusBarState = Application.DisplayStatusBar
    enableEventsState = Application.EnableEvents
    screenUpdatingState = Application.ScreenUpdating
    ' set the progress bar chars (should be equal size)
    BAR_CHAR = ChrW(9608)
    SPACE_CHAR = ChrW(9620)
    ' Set the desired state
    Application.DisplayStatusBar = True
    Application.ScreenUpdating = False
    Application.EnableEvents = False
End Sub

Private Sub Class_Terminate()
    ' Restore settings
    Application.DisplayStatusBar = statusBarState
    Application.ScreenUpdating = screenUpdatingState
    Application.EnableEvents = enableEventsState
    Application.StatusBar = False
End Sub

                  Optional ByVal MaxValue As Long= 0, _
                  Optional ByVal Status As String = "", _

    ' Value          : 0 to 100 (if no max is set)
    ' Value          : >=0 (if max is set)
    ' MaxValue       : >= 0
    ' Status         : optional message to display for user
    ' DisplayPercent : Display the percent complete after the status bar

    ' <Status> <Progress Bar> <Percent Complete>

    ' Validate entries
    If Value < 0 Or MaxValue < 0 Or (Value > 100 And MaxValue = 0) Then Exit Sub

    ' If the maximum is set then adjust value to be in the range 0 to 100
    If MaxValue > 0 Then Value = WorksheetFunction.RoundUp((Value * 100) / MaxValue, 0)

    ' Message to set the status bar to
    Dim display As String
    display = Status & "  "

    ' Set bars
    display = display & String(Int(Value / (100 / NUM_BARS)), BAR_CHAR)
    ' set spaces
    display = display & String(NUM_BARS - Int(Value / (100 / NUM_BARS)), SPACE_CHAR)

    ' Closing character to show end of the bar
    display = display & BAR_CHAR

    If DisplayPercent = True Then display = display & "  (" & Value & "%)  "

    ' chop off to the maximum length if necessary
    If Len(display) > MAX_LENGTH Then display = Right(display, MAX_LENGTH)

    Application.StatusBar = display
End Sub

Sample Usage:

Dim progressBar As New ProgressBar

For i = 1 To 100
    Call progressBar.Update(i, 100, "My Message Here", True)
    Application.Wait (Now + TimeValue("0:00:01"))

If nothing worked, try this.

$date = '25/05/2010'; //dd/mm/YYYY
$dateAr = explode('/',);
$date = $dateAr[2].'-'.$dateAr[1].'-'.$dateAr[0]; //YYYY-mm-dd

All sprints are iterations but not all iterations are sprints. Iteration is a common term in iterative and incremental development (IID). Scrum is one specialized flavor of IID so it makes sense to specialize the terminology as well. It also helps brand the methodology different from other IID methodologies :)

As to the sprint length: anything goes as long as the sprint is timeboxed i.e. it is finished on the planned date and not "when it's ready". (Or alternatively, in rare occasions, the sprint is terminated prematurely to start a new sprint in case some essential boundary conditions are changed.)

It does help to have the sprints of similar durations. There's less to remember about the sprint schedule and your planning gets more accurate. I like to keep mine at 2 calendar weeks, which will resolve into 8..10 business days outside holiday seasons.

REST in PHP can be done pretty simple. Create http://example.com/test.php (outlined below). Use this for REST calls, e.g. http://example.com/test.php/testing/123/hello. This works with Apache and Lighttpd out of the box, and no rewrite rules are needed.

<?php
$method = $_SERVER['REQUEST_METHOD'];
$request = explode("/", substr(@$_SERVER['PATH_INFO'], 1));

switch ($method) {
  case 'PUT':
    do_something_with_put($request);  
    break;
  case 'POST':
    do_something_with_post($request);  
    break;
  case 'GET':
    do_something_with_get($request);  
    break;
  default:
    handle_error($request);  
    break;
}

To match pattern or an empty string, use

^$|pattern

Explanation

• ^ and $ are the beginning and end of the string anchors respectively.
• | is used to denote alternates, e.g. this|that.

References

• regular-expressions.info/Anchors and Alternation

On \b

\b in most flavor is a "word boundary" anchor. It is a zero-width match, i.e. an empty string, but it only matches those strings at very specific places, namely at the boundaries of a word.

That is, \b is located:

• Between consecutive \w and \W (either order):
  • i.e. between a word character and a non-word character
• Between ^ and \w
  • i.e. at the beginning of the string if it starts with \w
• Between \w and $
  • i.e. at the end of the string if it ends with \w

References

• regular-expressions.info/Word Boundaries

Oracle Workshop for Weblogic is supposed to have a pretty nice jsp editor but I've never used it. You needn't be using Weblogic to use it.

A simpler scan would be:

String1.scan(/<(\S+)>/).last

I always use multiple statements with "-e"

$ sed -e 's:AND:\n&:g' -e 's:GROUP BY:\n&:g' -e 's:UNION:\n&:g' -e 's:FROM:\n&:g' file > readable.sql

This will append a '\n' before all AND's, GROUP BY's, UNION's and FROM's, whereas '&' means the matched string and '\n&' means you want to replace the matched string with an '\n' before the 'matched'

A slightly simplified version of Oglester's solution (the sequence doesn't require a select from DUAL:

INSERT INTO account_type_standard   
  (account_type_Standard_id, tax_status_id, recipient_id) 
VALUES(   
  account_type_standard_seq.nextval,
  (SELECT tax_status_id FROM tax_status WHERE tax_status_code = ?),
  (SELECT recipient_id FROM recipient WHERE recipient_code = ?)
)

best way is to create an accessor like this:

/**
* @var object $db : map to database connection.
*/
public static $db= null; 

/**
* db Function for initializing variable.   
* @return object
*/
public static function db(){
 if( !isset(static::$db) ){
  static::$db= new \Helpers\MySQL( array(
    "hostname"=> "localhost",
    "username"=> "root",
    "password"=> "password",
    "database"=> "db_name"
    )
  );
 }
 return static::$db;
}

then you can do static::db(); or self::db(); from anywhere.

Apart from the similarities i.e. Task.Run() being a shorthand for Task.Factory.StartNew(), there is a minute difference between their behaviour in case of sync and async delegates.

Suppose there are following two methods:

public async Task<int> GetIntAsync()
{
    return Task.FromResult(1);
}

public int GetInt()
{
    return 1;
}

Now consider the following code.

var sync1 = Task.Run(() => GetInt());
var sync2 = Task.Factory.StartNew(() => GetInt());

Here both sync1 and sync2 are of type Task<int>

However, difference comes in case of async methods.

var async1 = Task.Run(() => GetIntAsync());
var async2 = Task.Factory.StartNew(() => GetIntAsync());

In this scenario, async1 is of type Task<int>, however async2 is of type Task<Task<int>>

I came up with this while trying to figure out how to display currency ('$' to left, number to right) in table cells:

<div class="currency">20.34</div>

.currency {
   text-align: right;
}

.currency:before {
   content: "$";
   float: left;
   padding-right: 4px;
}

Try this in a Thread (not the UI-Thread):

final CountDownLatch latch = new CountDownLatch(1);
handler.post(new Runnable() {
  @Override
  public void run() {
    OnClickListener okListener = new OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
      dialog.dismiss();
      latch.countDown();
    }
  };

  AlertDialog dialog = new AlertDialog.Builder(context).setTitle(title)
    .setMessage(msg).setPositiveButton("OK", okListener).create();
  dialog.show();
}
});
try {
  latch.await();
} catch (InterruptedException e) {
  e.printStackTrace();
}

Another possibility is a mixture of release and debug builds in the dependencies. For example, Assembly A depends on Assembly B, A was built in Debug mode while the copy of B in GAC was built in Release mode, or vice versa.

A little mathematical logic theory here:

"NOT a AND NOT b" is the same as "NOT (a OR b)", so:

"a NOT -1 AND b NOT -1" is equivalent of "NOT (a is -1 OR b is -1)", which is opposite (Complement) of "(a is -1 OR b is -1)".

So if you want exact opposite result, df1 and df2 should be as below:

df1 = df[(df.a != -1) & (df.b != -1)]
df2 = df[(df.a == -1) | (df.b == -1)]

If you're dealing with files above 2 GB, you'll find that the above methods fail.

It's much easier just to hand the stream off to MD5 and allow that to chunk your file for you:

private byte[] computeFileHash(string filename)
{
    MD5 md5 = MD5.Create();
    using (FileStream fs = new FileStream(filename, FileMode.Open))
    {
        byte[] hash = md5.ComputeHash(fs);
        return hash;
    }
}

It will work.

long yourmilliseconds = System.currentTimeMillis();
SimpleDateFormat sdf = new SimpleDateFormat("MMM dd,yyyy HH:mm");    
Date resultdate = new Date(yourmilliseconds);
System.out.println(sdf.format(resultdate));

Use .ashx file type and use the same code

You can this query:

pip install image 

I had pillow installed, and still, I got the error that you mentioned. But after I executed the above command, the error vanished. And My program worked perfectly.

Tried this out quickly in the interactive shell:

>>> l = ['a', 'ab', 'abc', 'bac']
>>> [x for x in l if 'ab' in x]
['ab', 'abc']
>>>

Why does this work? Because the in operator is defined for strings to mean: "is substring of".

Also, you might want to consider writing out the loop as opposed to using the list comprehension syntax used above:

l = ['a', 'ab', 'abc', 'bac']
result = []
for s in l:
   if 'ab' in s:
       result.append(s)

we can be submit multiple updates together in JDBC to submit batch updates.

we can use Statement, PreparedStatement, and CallableStatement objects for bacth update with disable autocommit

addBatch() and executeBatch() functions are available with all statement objects to have BatchUpdate

here addBatch() method adds a set of statements or parameters to the current batch.

Using command prompt in windows you can use below command to get class files.

wsimport "complete file path of your .wsdl file"
example : wsimport C:\Users\schemas\com\myprofile\myprofile2019.wsdl

if you want to generate source code you should be using below commnad.

wsimport -keep -s src "complete file path of your .wsdl file"
example : wsimport -keep -s src C:\Users\schemas\com\myprofile\myprofile2019.wsdl

Note : Here "-s" means source directory and "src" is name of folder that should be created before executing this command. Wsimport is a tool which is bundled along with JAVA SE, no seperate download is required.

This issue is indeed usually caused by setting a parameter value to null as HLGEM mentioned above. I thought i would elaborate on some solutions to this problem that i have found useful for the benefit of people new to this problem.

The solution that i prefer is to default the stored procedure parameters to NULL (or whatever value you want), which was mentioned by sangram above, but may be missed because the answer is very verbose. Something along the lines of:

CREATE PROCEDURE GetEmployeeDetails
    @DateOfBirth    DATETIME = NULL,
    @Surname        VARCHAR(20),
    @GenderCode     INT = NULL,
AS

This means that if the parameter ends up being set in code to null under some conditions, .NET will not set the parameter and the stored procedure will then use the default value it has defined. Another solution, if you really want to solve the problem in code, would be to use an extension method that handles the problem for you, something like:

public static SqlParameter AddParameter<T>(this SqlParameterCollection parameters, string parameterName, T value) where T : class
{
    return value == null ? parameters.AddWithValue(parameterName, DBNull.Value) : parameters.AddWithValue(parameterName, value);
}

Matt Hamilton has a good post here that lists some more great extension methods when dealing with this area.

All OS comes with a default version of python and it resides in /usr/bin. All scripts that come with the OS (e.g. yum) point this version of python residing in /usr/bin. When you want to install a new version of python you do not want to break the existing scripts which may not work with new version of python.

The right way of doing this is to install the python as an alternate version.

e.g.
wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2 
tar xf Python-2.7.3.tar.bz2
cd Python-2.7.3
./configure --prefix=/usr/local/
make && make altinstall

Now by doing this the existing scripts like yum still work with /usr/bin/python. and your default python version would be the one installed in /usr/local/bin. i.e. when you type python you would get 2.7.3

This happens because. $PATH variable has /usr/local/bin before usr/bin.

/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

If python2.7 still does not take effect as the default python version you would need to do

export PATH="/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin"

Here is sample usage using expect:

#!/usr/bin/expect
set timeout 360
spawn my_command # Replace with your command.
expect "Do you want to continue?" { send "\r" }

Check: man expect for further information.

Use JSON classes for parsing e.g

JSONObject mainObject = new JSONObject(Your_Sring_data);
JSONObject uniObject = mainObject.getJSONObject("university");
String  uniName = uniObject.getString("name");
String uniURL = uniObject.getString("url");

JSONObject oneObject = mainObject.getJSONObject("1");
String id = oneObject.getString("id");
....

The solution from PSL will not work in Firefox. FF accepts event only as a formal parameter. So you have to find another way to identify the selected row. My solution is something like this:

...
$('#mySelector')
  .on('show.bs.modal', function(e) {
  var mid;


  if (navigator.userAgent.toLowerCase().indexOf('firefox') > -1) 
    mid = $(e.relatedTarget).data('id');
  else
    mid = $(event.target).closest('tr').data('id');

...

You are looking to see if a single value is in an array. Use in_array.

However note that case is important, as are any leading or trailing spaces. Use var_dump to find out the length of the strings too, and see if they fit.

str.erase(str.begin() + str.size() - 1)

str.erase(str.rbegin()) does not compile unfortunately, since reverse_iterator cannot be converted to a normal_iterator.

C++11 is your friend in this case.

you can also quote string

''+document.location+''.substring(2,3);

Two Methods for Passing Multiple route params in Angular

Method-1

In app.module.ts

Set path as component2.

imports: [
 RouterModule.forRoot(
 [ {path: 'component2/:id1/:id2', component: MyComp2}])
]

Call router to naviagte to MyComp2 with multiple params id1 and id2.

export class MyComp1 {
onClick(){
    this._router.navigate( ['component2', "id1","id2"]);
 }
}

Method-2

In app.module.ts

Set path as component2.

imports: [
 RouterModule.forRoot(
 [ {path: 'component2', component: MyComp2}])
]

Call router to naviagte to MyComp2 with multiple params id1 and id2.

export class MyComp1 {
onClick(){
    this._router.navigate( ['component2', {id1: "id1 Value", id2: 
    "id2  Value"}]);
 }
}

You could use JavaScript and XMLHTTPRequest (AJAX) to perform a POST without using a form. Check this link out. Keep in mind that you will need JavaScript enabled in your browser though.

Depending on what kind of image you have, it might be better to rework the design so that the main image fades to a set solid color or repeatable pattern. If you center the image in the page and have the solid color as the backgroud.

To convert the byte[] to string[], simply use the below line.

byte[] fileData; // Some byte array
//Convert byte[] to string[]
var table = (Encoding.Default.GetString(
                 fileData, 
                 0, 
                 fileData.Length - 1)).Split(new string[] { "\r\n", "\r", "\n" },
                                             StringSplitOptions.None);

As you noticed, these are Makefile {macros or variables}, not compiler options. They implement a set of conventions. (Macros is an old name for them, still used by some. GNU make doc calls them variables.)

The only reason that the names matter is the default make rules, visible via make -p, which use some of them.

If you write all your own rules, you get to pick all your own macro names.

In a vanilla gnu make, there's no such thing as CCFLAGS. There are CFLAGS, CPPFLAGS, and CXXFLAGS. CFLAGS for the C compiler, CXXFLAGS for C++, and CPPFLAGS for both.

Why is CPPFLAGS in both? Conventionally, it's the home of preprocessor flags (-D, -U) and both c and c++ use them. Now, the assumption that everyone wants the same define environment for c and c++ is perhaps questionable, but traditional.

P.S. As noted by James Moore, some projects use CPPFLAGS for flags to the C++ compiler, not flags to the C preprocessor. The Android NDK, for one huge example.

I ran into this exact same error message. I tried Aditi's example, and then I realized what the real issue was. (Because I had another apiEndpoint making a similar call that worked fine.) In this case The object in my list had not had an interface extracted from it yet. So because I apparently missed a step, when it went to do the bind to the

List<OfthisModelType>

It failed to deserialize.

If you see this issue, check to see if that could be the issue.

I'll like to add to this post, that I was experienceing the same issue but in a PartialView.

And I needed to add

<script src="~/Scripts/jquery.validate.unobtrusive.min.js"></script>

To the partial view, even if already present in the _Layout view.

You're on the right track. You may read the user input into an integer and switch on that:

enum Choice
{
  EASY = 1, 
  MEDIUM = 2, 
  HARD = 3
};

int i = -1;

// ...<present the user with a menu>...

cin >> i;

switch(i)
{
  case EASY:
    cout << "Easy\n";
    break;
  case MEDIUM:
    cout << "Medium\n";
    break;
  case HARD:
    cout << "Hard\n";
    break;
  default:
    cout << "Invalid Selection\n";
    break;
}

Object.defineProperty(window, 'propertyName', {
    set: value => {
        this._value = value;
        // someAction();
    },
    get: () => this._value
});

or even if you just want this property to be passed as an argument to a function and don't need it to be defined on a global object:

Object.defineProperty(window, 'propertyName', { set: value => someAction(value) })

However, since in your example you seem to want to perform an action upon creation of a node, I would suggest you take a look at MutationObservers.

In native Hibernate XML mappings, you can accomplish this by declaring a one-to-one mapping with the constrained attribute set to true. I am not sure what the Hibernate/JPA annotation equivalent of that is, and a quick search of the doc provided no answer, but hopefully that gives you a lead to go on.

I would always recommend going to the authoritative source when trying to understand the meaning and purpose of HTTP headers.

The "Host" header field in a request provides the host and port
information from the target URI, enabling the origin server to
distinguish among resources while servicing requests for multiple
host names on a single IP address.

I had the same issue in VS2015. I have solved it by compiling the SDL2 sources in VS2015.

1. Go to http://libsdl.org/download-2.0.php and download SDL 2 source code.
2. Open SDL_VS2013.sln in VS2015. You will be asked to convert the projects. Do it.
3. Compile SDL2 project.
4. Compile SDL2main project.
5. Use the new generated output files SDL2main.lib, SDL2.lib and SDL2.dll in your SDL 2 project in VS2015.

I know it's not exactly what you're asking, but, for replacing a comma with a newline, this works great:

tr , '\n' < file

IIRC they suggest using the preg_ functions instead (in this case, preg_replace).

If you'd like your script to install missing packages and continue, you could do something like this (on example of 'krbV' module in 'python-krbV' package):

import pip
import sys

for m, pkg in [('krbV', 'python-krbV')]:
    try:
        setattr(sys.modules[__name__], m, __import__(m))
    except ImportError:
        pip.main(['install', pkg])
        setattr(sys.modules[__name__], m, __import__(m))

You can get good Time Series graphs in Excel, the way you want, but you have to work with a few quirks.

1. Be sure to select "Scatter Graph" (with a line option). This is needed if you have non-uniform time stamps, and will scale the X-axis accordingly.

2. In your data, you need to add a column with the mid-point. Here's what I did with your sample data. (This trick ensures that the data gets plotted at the mid-point, like you desire.)

3. You can format the x-axis options with this menu. (Chart->Design->Layout)

4. Select "Axes" and go to Primary Horizontal Axis, and then select "More Primary Horizontal Axis Options"

5. Set up the options you wish. (Fix the starting and ending points.)

6. And you will get a graph such as the one below.

You can then tweak many of the options, label the axes better etc, but this should get you started.

Hope this helps you move forward.

There is a useful undocumented method in the ZipArchive class: addGlob();

$zipFile = "./testZip.zip";
$zipArchive = new ZipArchive();

if ($zipArchive->open($zipFile, (ZipArchive::CREATE | ZipArchive::OVERWRITE)) !== true)
    die("Failed to create archive\n");

$zipArchive->addGlob("./*.txt");
if ($zipArchive->status != ZIPARCHIVE::ER_OK)
    echo "Failed to write files to zip\n";

$zipArchive->close();

Now documented at: www.php.net/manual/en/ziparchive.addglob.php

You can't close a current window or any window or page that is opened using '_self' But you can do this

var customWindow = window.open('', '_blank', '');
    customWindow.close();

Something like:

if(divisor == 0) {
  throw new ArithmeticException("Division by zero!");
}

The spirit of Web font is to use cache as much as possible, therefore you should use CDN version between <head></head> instead of hosting yourself:

<link href="//netdna.bootstrapcdn.com/font-awesome/3.2.1/css/font-awesome.css" rel="stylesheet">

Also, make sure you loaded your CSS AFTER the above line, or your custom font CSS won't work.

The existing answers missed an option, so here's a complete list:

// 1. Explicitly declare the type
var arr: Criminal[] = [];

// 2. Via type assertion
var arr = <Criminal[]>[];
var arr = [] as Criminal[];

// 3. Using the Array constructor
var arr = new Array<Criminal>();

1. Explicitly specifying the type is the general solution for whenever type inference fails for a variable declaration.

2. The advantage of using a type assertion (sometimes called a cast, but it's not really a cast in TypeScript) works for any expression, so it can be used even when no variable is declared. There are two syntaxes for type assertions, but only the latter will work in combination with JSX if you care about that.

3. Using the Array constructor is something that will only help you in this specific use case, but which I personally find the most readable. However, there is a slight performance impact at runtime*. Also, if someone were crazy enough to redefine the Array constructor, the meaning could change.

It's a matter of personal preference, but I find the third option the most readable. In the vast majority of cases the mentioned downsides would be negligible and readability is the most important factor.

*: Fun fact; at the time of writing the performance difference was 60% in Chrome, while in Firefox there was no measurable performance difference.

Interestingly enough, it is possible to initialize arrays in any way at any time in the program, provided they are members of a struct or union.

Example program:

#include <stdio.h>

struct ccont
{
  char array[32];
};

struct icont
{
  int array[32];
};

int main()
{
  int  cnt;
  char carray[32] = { 'A', 66, 6*11+1 };    // 'A', 'B', 'C', '\0', '\0', ...
  int  iarray[32] = { 67, 42, 25 };

  struct ccont cc = { 0 };
  struct icont ic = { 0 };

  /*  these don't work
  carray = { [0]=1 };           // expected expression before '{' token
  carray = { [0 ... 31]=1 };    // (likewise)
  carray = (char[32]){ [0]=3 }; // incompatible types when assigning to type 'char[32]' from type 'char *'
  iarray = (int[32]){ 1 };      // (likewise, but s/char/int/g)
  */

  // but these perfectly work...
  cc = (struct ccont){ .array='a' };        // 'a', '\0', '\0', '\0', ...
  // the following is a gcc extension, 
  cc = (struct ccont){ .array={ [0 ... 2]='a' } };  // 'a', 'a', 'a', '\0', '\0', ...
  ic = (struct icont){ .array={ 42,67 } };      // 42, 67, 0, 0, 0, ...
  // index ranges can overlap, the latter override the former
  // (no compiler warning with -Wall -Wextra)
  ic = (struct icont){ .array={ [0 ... 1]=42, [1 ... 2]=67 } }; // 42, 67, 67, 0, 0, ...

  for (cnt=0; cnt<5; cnt++)
    printf("%2d %c %2d %c\n",iarray[cnt], carray[cnt],ic.array[cnt],cc.array[cnt]);

  return 0;
}

My main advice would be to steer clear of the HAVING clause (see below):

WITH HighEarners AS
     ( SELECT EmpId, DeptId
         FROM EMPLOYEE
        WHERE Salary > 1000 ), 
     DeptmentHighEarnerTallies AS 
     ( SELECT DeptId, COUNT(*) AS HighEarnerTally
         FROM HighEarners
        GROUP 
           BY DeptId )
SELECT DeptName
  FROM DEPARTMENT NATURAL JOIN DeptmentHighEarnerTallies
 WHERE HighEarnerTally > 2;

The very early SQL implementations lacked derived tables and HAVING was a workaround for one of its most obvious drawbacks (how to select on the result of a set function from the SELECT clause). Once derived tables had become a thing, the need for HAVING went away. Sadly, HAVING itself didn't go away (and never will) because nothing is ever removed from standard SQL. There is no need to learn HAVING and I encourage fledgling coders to avoid using this historical hangover.

I had the same problem, but running it as an admin worked.

You should be able to access the query using dot notation now.

If you want to access say you are receiving a GET request at /checkEmail?type=email&utm_source=xxxx&email=xxxxx&utm_campaign=XX and you want to fetch out the query used.

var type = req.query.type,
    email = req.query.email,
    utm = {
     source: req.query.utm_source,
     campaign: req.query.utm_campaign
    };

Params are used for the self defined parameter for receiving request, something like (example):

router.get('/:userID/food/edit/:foodID', function(req, res){
 //sample GET request at '/xavg234/food/edit/jb3552'

 var userToFind = req.params.userID;//gets xavg234
 var foodToSearch = req.params.foodID;//gets jb3552
 User.findOne({'userid':userToFind}) //dummy code
     .then(function(user){...})
     .catch(function(err){console.log(err)});
});

For making a call activity using intents, you should request the proper permissions.

For that you include uses permissions in AndroidManifest.xml file.

<uses-permission android:name="android.permission.CALL_PHONE" />

Then include the following code in your activity

if (ActivityCompat.checkSelfPermission(mActivity,
        Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
    //Creating intents for making a call
    Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("tel:123456789"));
    mActivity.startActivity(callIntent);

}else{
    Toast.makeText(mActivity, "You don't assign permission.", Toast.LENGTH_SHORT).show();
}

I recently purchased a MacBook Air (mid-2011 model) and was really happy to find that Apple officially supports Windows 7. If you purchase Windows 7 (I got DSP), you can use the Boot Camp assistant in OSX to designate part of your hard drive to Windows. Then you can install and run Windows 7 natively as if it were as Windows notebook.

I use Visual Studio 2010 on Windows 7 on my MacBook Air (I kept OSX as well) and I could not be happier. Heck, the initial start-up of the program only takes 3 seconds thanks to the SSD.

As others have mentions, you can run it on OSX using Parallels, etc. but I prefer to run it natively.

The Clear method is defined as

    public void Clear() { 
        Text = null;
    } 

The Text property's setter starts with

        set { 
            if (value == null) { 
                value = "";
            } 

I assume this answers your question.

In my case I try this:

sudo apt install openjdk-11-jdk-headless
sudo apt install openjdk-8-jdk-headless

I use openjdk

try this:

puts 'one TWO three foUR'.split.map(&:capitalize).join(' ')

#=> One Two Three Four

or

puts 'one TWO three foUR'.split.map(&:capitalize)*' '

Never alter the container you're looping on, because iterators on that container are not going to be informed of your alterations and, as you've noticed, that's quite likely to produce a very different loop and/or an incorrect one. In normal cases, looping on a copy of the container helps, but in your case it's clear that you don't want that, as the container will be empty after 50 legs of the loop and if you then try popping again you'll get an exception.

What's anything BUT clear is, what behavior are you trying to achieve, if any?! Maybe you can express your desires with a while...?

i = 0
while i < len(some_list):
    print i,                         
    print some_list.pop(0),                  
    print some_list.pop(0)

I had this issue, I run 64 bit Windows and had downloaded the 64 bit TOAD package. I finally arrived at the conclusion that it was because I unzipped the package in a windows share using cygwin command line unzip. Turned out TOAD wasn't liking the permissions on some files. When I unzipped using windows File Explorer everything worked as expected.

The derived table would work, but if this is SQL 2005, a CTE and ROW_NUMBER might be cleaner:

WITH UserStatus (User, Date, Status, Notes, Ord)
as
(
SELECT Date, User, Status, Notes, 
     ROW_NUMBER() OVER (PARTITION BY User ORDER BY Date DESC)
FROM [SOMETABLE]
)

SELECT User, Date, Status, Notes from UserStatus where Ord = 1

This would also facilitate the display of the most recent x statuses from each user.

In my case, (windows OS), after put all those commands listed, npm kept taking the proxy in the setting of windows registry

\ HKEY_CURRENT_USER \ Environment

just remove the proxy settings there, after that, I restarted the pc and then "npm install" worked for me

Example

Assuming doc is your instance of org.w3c.dom.Document:

TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
StringWriter writer = new StringWriter();
transformer.transform(new DOMSource(doc), new StreamResult(writer));
String output = writer.getBuffer().toString().replaceAll("\n|\r", "");

What I would do is comment out the Dockerfile below and including the offending line. Then you can run the container and run the docker commands by hand, and look at the logs in the usual way. E.g. if the Dockerfile is

RUN foo
RUN bar
RUN baz

and it's dying at bar I would do

RUN foo
# RUN bar
# RUN baz

Then

$ docker build -t foo .
$ docker run -it foo bash
container# bar
...grep logs...

An alternative to Ctrl+A, Ctrl+K is Ctrl+E, Ctrl+U.

I've patched my project with JailCoder http://jailcoder.com/ and problem resolved. Just download It and drag your xcode project to It.

This just works:

$body = @{
 "UserSessionId"="12345678"
 "OptionalEmail"="[email protected]"
} | ConvertTo-Json

$header = @{
 "Accept"="application/json"
 "connectapitoken"="97fe6ab5b1a640909551e36a071ce9ed"
 "Content-Type"="application/json"
} 

Invoke-RestMethod -Uri "http://MyServer/WSVistaWebClient/RESTService.svc/member/search" -Method 'Post' -Body $body -Headers $header | ConvertTo-HTML

I normally create a static method on form/dialog, that I can call. This returns the success (OK-button) or failure, along with the values that needs to be filled in.

 public class ResultFromFrmMain {
     public DialogResult Result { get; set; }
     public string Field1 { get; set; }


 }

And on the form:

public static ResultFromFrmMain Execute() {
     using (var f = new frmMain()) {
          var result = new ResultFromFrmMain();
          result.Result = f.ShowDialog();
          if (result.Result == DialogResult.OK) {
             // fill other values
          }
          return result;
     }
}

To call your form;

public void MyEventToCallForm() {
   var result = frmMain.Execute();
   if (result.Result == DialogResult.OK) {
       myTextBox.Text = result.Field1; // or something like that
   }
}

The file object is a buffer. When you read from the buffer, that portion that you read is consumed (the read position is shifted forward). When you read through the entire file, the read position is at the end of the file (EOF), so it returns nothing because there is nothing left to read.

If you have to reset the read position on a file object for some reason, you can do:

f.seek(0)

A little stale post, but I figured what the heck. Does "whoami" meet your needs?

I just found out about it today (from the same Google search that brought me here, in fact). Windows has had a whoami tool since XP (part of an add on toolkit) and has been built-in since Vista.

whoami /groups

Lists all the AD groups for the currently logged-on user. I believe it does require you to be logged on AS that user, though, so this won't help if your use case requires the ability to run the command to look at another user.

Group names only:

whoami /groups /fo list |findstr /c:"Group Name:"

It depends on the tools you can use. I doubt there is a JavaScript too that could do it directly within the browser. It also depends if it's a one-off (always the same key) or whether you need to script it.

Command-line / OpenSSL

If you want to use something like OpenSSL on a unix command line, you can do something as follows. I'm assuming you public.key file contains something like this:

-----BEGIN PUBLIC KEY-----
MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAmBAjFv+29CaiQqYZIw4P
J0q5Qz2gS7kbGleS3ai8Xbhu5n8PLomldxbRz0RpdCuxqd1yvaicqpDKe/TT09sR
mL1h8Sx3Qa3EQmqI0TcEEqk27Ak0DTFxuVrq7c5hHB5fbJ4o7iEq5MYfdSl4pZax
UxdNv4jRElymdap8/iOo3SU1RsaK6y7kox1/tm2cfWZZhMlRFYJnpoXpyNYrp+Yo
CNKxmZJnMsS698kaFjDlyznLlihwMroY0mQvdD7dCeBoVlfPUGPAlamwWyqtIU+9
5xVkSp3kxcNcNb/mePSKQIPafQ1sAmBKPwycA/1I5nLzDVuQa95ZWMn0JkphtFIh
HQIDAQAB
-----END PUBLIC KEY-----

Then, the commands would be:

PUBKEY=`grep -v -- ----- public.key | tr -d '\n'`

Then, you can look into the ASN.1 structure:

echo $PUBKEY | base64 -d | openssl asn1parse -inform DER -i

This should give you something like this:

    0:d=0  hl=4 l= 290 cons: SEQUENCE          
    4:d=1  hl=2 l=  13 cons:  SEQUENCE          
    6:d=2  hl=2 l=   9 prim:   OBJECT            :rsaEncryption
   17:d=2  hl=2 l=   0 prim:   NULL              
   19:d=1  hl=4 l= 271 prim:  BIT STRING 

The modulus and public exponent are in the last BIT STRING, offset 19, so use -strparse:

 echo $PUBKEY | base64 -d | openssl asn1parse -inform DER -i -strparse 19

This will give you the modulus and the public exponent, in hexadecimal (the two INTEGERs):

    0:d=0  hl=4 l= 266 cons: SEQUENCE          
    4:d=1  hl=4 l= 257 prim:  INTEGER           :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
  265:d=1  hl=2 l=   3 prim:  INTEGER           :010001

That's probably fine if it's always the same key, but this is probably not very convenient to put in a script.

Alternatively (and this might be easier to put into a script),

openssl rsa -pubin -inform PEM -text -noout < public.key

will return this:

Java

It depends on the input format. If it's an X.509 certificate in a keystore, use (RSAPublicKey)cert.getPublicKey(): this object has two getters for the modulus and the exponent.

If it's in the format as above, you might want to use BouncyCastle and its PEMReader to read it. I haven't tried the following code, but this would look more or less like this:

PEMReader pemReader = new PEMReader(new FileReader("file.pem"));
Object obj = pemReader.readObject();
pemReader.close();
if (obj instanceof X509Certificate) {
   // Just in case your file contains in fact an X.509 certificate,
   // useless otherwise.
   obj = ((X509Certificate)obj).getPublicKey();
}
if (obj instanceof RSAPublicKey) {
   // ... use the getters to get the BigIntegers.
}

(You can use BouncyCastle similarly in C# too.)

* { font-family: Algerian; }

The universal selector * refers to any element.

No there is no built-in String method. You can convert it to a char array, sort it using Arrays.sort and convert that back into a String.

String test= "edcba";
char[] ar = test.toCharArray();
Arrays.sort(ar);
String sorted = String.valueOf(ar);

Or, when you want to deal correctly with locale-specific stuff like uppercase and accented characters:

import java.text.Collator;
import java.util.Arrays;
import java.util.Comparator;
import java.util.Locale;

public class Test
{
  public static void main(String[] args)
  {
    Collator collator = Collator.getInstance(new Locale("fr", "FR"));
    String original = "éDedCBcbAàa";
    String[] split = original.split("");
    Arrays.sort(split, collator);
    String sorted = "";
    for (int i = 0; i < split.length; i++)
    {
      sorted += split[i];
    }
    System.out.println(sorted); // "aAàbBcCdDeé"
  }
}

  addClass(element, className1, className2){
    element.classList.add(className1, className2);
  }
  removeClass(element, className1, className2) {
    element.classList.remove(className1, className2);
  }

removeClass(myElement, 'myClass1', 'myClass2');
addClass(myElement, 'myClass1', 'myClass2');

Let's dissect it. There are three parts:

1. cd -- This is change directory command.
2. /d -- This switch makes cd change both drive and directory at once. Without it you would have to do cd %~d0 & cd %~p0. (%~d0 Changs active drive, cd %~p0 change the directory).
3. %~dp0 -- This can be dissected further into three parts:
   1. %0 -- This represents zeroth parameter of your batch script. It expands into the name of the batch file itself.
   2. %~0 -- The ~ there strips double quotes (") around the expanded argument.
   3. %dp0 -- The d and p there are modifiers of the expansion. The d forces addition of a drive letter and the p adds full path.

Use the following line

android:nextFocusDown="@+id/parentedit"

parentedit is the ID of the next EditText to be focused.

The above line will also need the following line.

android:inputType="text"

or

android:inputType="number"

Thanks for the suggestion @Alexei Khlebnikov.

This works for me for BlueStacks 4:

• Install "Rotation Control" app
• Enable it to appear onto taskbar; optionally with system start
• Whenever you want to rotate the screen, just pull down the task bar, and give it a go

function getWindowRelativeOffset(parentWindow, elem) {
        var offset = {
            left : 0,
            top : 0
        };
        // relative to the target field's document
        offset.left = elem.getBoundingClientRect().left;
        offset.top = elem.getBoundingClientRect().top;
        // now we will calculate according to the current document, this current
        // document might be same as the document of target field or it may be
        // parent of the document of the target field
        var childWindow = elem.document.frames.window;
        while (childWindow != parentWindow) {
            offset.left = offset.left + childWindow.frameElement.getBoundingClientRect().left;
            offset.top = offset.top + childWindow.frameElement.getBoundingClientRect().top;
            childWindow = childWindow.parent;
        }
        return offset;
    };

you can call it like this

getWindowRelativeOffset(top, inputElement);

I focus for IE only as per my requirement but similar can be done for other browsers

Django 1.11 delete all objects from a database table -

Entry.objects.all().delete()  ## Entry being Model Name. 

Refer the Official Django documentation here as quoted below - https://docs.djangoproject.com/en/1.11/topics/db/queries/#deleting-objects

Note that delete() is the only QuerySet method that is not exposed on a Manager itself. This is a safety mechanism to prevent you from accidentally requesting Entry.objects.delete(), and deleting all the entries. If you do want to delete all the objects, then you have to explicitly request a complete query set:

I myself tried the code snippet seen below within my somefilename.py

    # for deleting model objects
    from django.db import connection
    def del_model_4(self):
        with connection.schema_editor() as schema_editor:
            schema_editor.delete_model(model_4)

and within my views.py i have a view that simply renders a html page ...

  def data_del_4(request):
      obj = calc_2() ## 
      obj.del_model_4()
      return render(request, 'dc_dash/data_del_4.html') ## 

it ended deleting all entries from - model == model_4 , but now i get to see a Error screen within Admin console when i try to asceratin that all objects of model_4 have been deleted ...

ProgrammingError at /admin/dc_dash/model_4/
relation "dc_dash_model_4" does not exist
LINE 1: SELECT COUNT(*) AS "__count" FROM "dc_dash_model_4" 

Do consider that - if we do not go to the ADMIN Console and try and see objects of the model - which have been already deleted - the Django app works just as intended.

django admin screencapture

Three steps needed:

1. Explicitly mark SSL2.0, TLS1.0, TLS1.1 as forbidden on your server machine, by adding Enabled=0 and DisabledByDefault=1 to your registry (the full path is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols). See screen for details

2. Explicitly enable TLS1.2 by following the steps from 1. Just use Enabled=1 and DisabledByDefault=0 respectively.

NOTE: verify server version: Windows Server 2003 does not support the TLS 1.2 protocol

3. Enable TLS1.2 only on app level, like @John Wu suggested above.

   System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Hope this guide helps.

UPDATE As @Subbu mentioned: Official guide

Right click the project and select clean the project. Or else completely empty the bin directory and then re-build again. This should clear of any left over assemblies from previous builds

NUMBER (precision, scale) means precision number of total digits, of which scale digits are right of the decimal point.

NUMBER(2,2) in other words means a number with 2 digits, both of which are decimals. You may mean to use NUMBER(4,2) to get 4 digits, of which 2 are decimals. Currently you can just insert values with a zero integer part.

Frontend refers to the client-side, whereas backend refers to the server-side of the application. Both are crucial to web development, but their roles, responsibilities and the environments they work in are totally different. Frontend is basically what users see whereas backend is how everything works

i've try a lot of ways, but only this work for me

thanks for workaround

check your .env

MYSQL_VERSION=latest

then type this command

$ docker-compose exec mysql bash
$ mysql -u root -p 

(login as root)

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root';
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'root';
ALTER USER 'default'@'%' IDENTIFIED WITH mysql_native_password BY 'secret';

then go to phpmyadmin and login as :

• host -> mysql
• user -> root
• password -> root

hope it help

Try to use TranslateAnimation class, which creates the animation for position changes. Try reading this for help - http://developer.android.com/reference/android/view/animation/TranslateAnimation.html

Update: Here's the example for this. If you have the height of your view as 50 and in the hide mode you want to show only 10 px. The sample code would be -

TranslateAnimation anim=new TranslateAnimation(0,0,-40,0);
anim.setFillAfter(true);
view.setAnimation(anim);

PS: There are lot's or other methods there to help you use the animation according to your need. Also have a look at the RelativeLayout.LayoutParams if you want to completely customize the code, however using the TranslateAnimation is easier to use.

EDIT:-Complex version using LayoutParams

RelativeLayout relParam=new RelativeLayout.LayoutParam(RelativeLayout.LayoutParam.FILL_PARENT,RelativeLayout.LayoutParam.WRAP_CONTENT); //you can give hard coded width and height here in (width,height) format.
relParam.topMargin=-50; //any number that work.Set it to 0, when you want to show it.
view.setLayoutParams(relparam);

This example code assumes you are putting your view in RelativeLayout, if not change the name of Layout, however other layout might not work. If you want to give an animation effect on them, reduce or increase the topMargin slowly. You can consider using Thread.sleep() there too.

Project Lombok provides an annotation @ExtensionMethod that can be used to achieve the functionality you are asking for.

Group your report data based on the category that you want your sheets to be based on. Specify that you want that grouping to start a new page for every new category. Each page becomes a new worksheet in the Excel workbook.

Note: I use SQL Server 2003 and Excel 2003.

It's not very clear what the problem is and what you are trying to accomplish from the code you posted, but I'll take a stab at it.

In general, I suggest calling a function on ng-click like so:

<a ng-click="navigateToPath()">click me</a>

obj.val1 & obj.val2 should be available on your controller's $scope, you dont need to pass those into a function from the markup.

then, in your controller:

$scope.navigateToPath = function(){
   var path = '/somePath/' + $scope.obj.val1 + '/' + $scope.obj.val2; //dont need the '#'
   $location.path(path)       
}

I have occurred the same error look following example-

async.waterfall([function(waterCB) {
    waterCB(null);
}, function(**inputArray**, waterCB) {
    waterCB(null);
}], function(waterErr, waterResult) {
    console.log('Done');
});

In the above waterfall function, I am accepting inputArray parameter in waterfall 2nd function. But this inputArray not passed in waterfall 1st function in waterCB.

Cheak your function parameters Below are a correct example.

async.waterfall([function(waterCB) {
    waterCB(null, **inputArray**);
}, function(**inputArray**, waterCB) {
    waterCB(null);
}], function(waterErr, waterResult) {
    console.log('Done');
});

Thanks

This might be just a requirement of PyMySql in Python, but I found that I had to name the exact table that I wanted the ID for:

In:

cnx = pymysql.connect(host='host',
                            database='db',
                            user='user',
                            password='pass')
cursor = cnx.cursor()
update_batch = """insert into batch set type = "%s" , records = %i, started = NOW(); """
second_query = (update_batch % ( "Batch 1", 22  ))
cursor.execute(second_query)
cnx.commit()
batch_id = cursor.execute('select last_insert_id() from batch')
cursor.close()

batch_id

Out: 5
... or whatever the correct Batch_ID value actually is

I did it in this way.

In tasks/main.yml

- name: template test
  template: 
        src=myTemplateFile.j2
        dest={{item}}
   with_dict: some_dict

and in vars/main.yml

some_dict:
  /path/to/dest1:
    var1: 1
    var2: 2
  /path/to/dest2:
    var1: 3
    var2: 4

and in templates/myTemplateFile.j2

some_var = {{ item.value.var1 }}
some_other_var = {{ item.value.var2 }}

Hope this solves your problem.

You're going to have to rely on each individual's machine having the correct file associations. If you try and open the application from JavaScript/VBScript in a web page, the spawned application is either going to itself be sandboxed (meaning decreased permissions) or there are going to be lots of security prompts.

My suggestion is to look to SharePoint server for this one. This is something that we know they do and you can edit in place, but the question becomes how they manage to pull that off. My guess is direct integration with Office. Either way, this isn't something that the Internet is designed to do, because I'm assuming you want them to edit the original document and not simply create their own copy (which is what the default behavior of file:// would be.

So depending on you options, it might be possible to create a client side application that gets installed on all your client machines and then responds to a particular file handler that says go open this application on the file server. Then it wouldn't really matter who was doing it since all browsers would simply hand off the request to you. You would have to create your own handler like fileserver://.

Don't forget to import Foundation or UIKit.

import Foundation
let trimmedString = "   aaa  "".trimmingCharacters(in: .whitespaces)
print(trimmedString)

Result:

"aaa"

Otherwise you'll get:

error: value of type 'String' has no member 'trimmingCharacters'
    return self.trimmingCharacters(in: .whitespaces)

The script tag to the api has changed recently. Use something like this to query the Geocoding API and get the JSON object back

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/geocode/json?address=THE_ADDRESS_YOU_WANT_TO_GEOCODE&key=YOUR_API_KEY"></script>

The address could be something like

1600+Amphitheatre+Parkway,+Mountain+View,+CA (URI Encoded; you should Google it. Very useful)

or simply

1600 Amphitheatre Parkway, Mountain View, CA

By entering this address https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=YOUR_API_KEY inside the browser, along with my API Key, I get back a JSON object which contains the Latitude & Longitude for the city of Moutain view, CA.

{"results" : [
  {
     "address_components" : [

Web Frameworks such like AngularJS allow us to perform these queries with ease.

In Rails

If you need

• a "pretty printed" Hash
• in e.g. the Rails.logger
• that, specifically, runs inspect on the objects in the Hash
  • which is useful if you override/define the inspect method in your objects like you're supposed to

... then this works great! (And gets better, the bigger and more nested your Hash object is.)

logger.error my_hash.pretty_inspect

For example:

class MyObject1
  def inspect
    "<#{'*' * 10} My Object 1 #{'*' * 10}>"
  end
end

class MyObject2
  def inspect
    "<#{'*' * 10} My Object 2 #{'*' * 10}>"
  end
end

my_hash = { a: 1, b: MyObject1.new, MyObject2.new => 3 }

Rails.logger.error my_hash
# {:a=>1, :b=><********** My Object 1 **********>, <********** My Object 2 **********>=>3}

# EW! ^

Rails.logger.error my_hash.pretty_inspect
# {:a=>1,
#  :b=><********** My Object 1 **********>,
#  <********** My Object 2 **********>=>3}

pretty_inspect comes from PrettyPrint, which rails includes by default. So, no gems needed and no conversion to JSON needed.

Not In Rails

If you're not in Rails or if the above fails for some reason, try using require "pp" first. For example:

require "pp"  # <-----------

class MyObject1
  def inspect
    "<#{'*' * 10} My Object 1 #{'*' * 10}>"
  end
end

class MyObject2
  def inspect
    "<#{'*' * 10} My Object 2 #{'*' * 10}>"
  end
end

my_hash = { a: 1, b: MyObject1.new, MyObject2.new => 3 }

puts my_hash
# {:a=>1, :b=><********** My Object 1 **********>, <********** My Object 2 **********>=>3}

# EW! ^

puts my_hash.pretty_inspect
# {:a=>1,
#  :b=><********** My Object 1 **********>,
#  <********** My Object 2 **********>=>3}

A Full Example

Use jQuery's function jQuery.inArray

jQuery.inArray( value, array [, fromIndex ] )
(or) $.inArray( value, array [, fromIndex ] )

You can get current Fragment from fragmentManager. And if there are non of them in fragment manager you can create Fragment_1

public class MainActivity extends FragmentActivity {


    public static Fragment_1 fragment_1;
    public static Fragment_2 fragment_2;
    public static Fragment_3 fragment_3;
    public static FragmentManager fragmentManager;


    @Override
    protected void onCreate(Bundle arg0) {
        super.onCreate(arg0);
        setContentView(R.layout.main);

        fragment_1 = (Fragment_1) fragmentManager.findFragmentByTag("fragment1");

        fragment_2  =(Fragment_2) fragmentManager.findFragmentByTag("fragment2");

        fragment_3 = (Fragment_3) fragmentManager.findFragmentByTag("fragment3");


        if(fragment_1==null && fragment_2==null && fragment_3==null){           
            fragment_1 = new Fragment_1();          
            fragmentManager.beginTransaction().replace(R.id.content_frame, fragment_1, "fragment1").commit();
        }


    }


}

also you can use setRetainInstance to true what it will do it ignore onDestroy() method in fragment and your application going to back ground and os kill your application to allocate more memory you will need to save all data you need in onSaveInstanceState bundle

public class Fragment_1 extends Fragment {


    private EditText title;
    private Button go_next;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setRetainInstance(true); //Will ignore onDestroy Method (Nested Fragments no need this if parent have it)
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        onRestoreInstanceStae(savedInstanceState);
        return super.onCreateView(inflater, container, savedInstanceState);
    }


    //Here you can restore saved data in onSaveInstanceState Bundle
    private void onRestoreInstanceState(Bundle savedInstanceState){
        if(savedInstanceState!=null){
            String SomeText = savedInstanceState.getString("title");            
        }
    }

    //Here you Save your data
    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        outState.putString("title", "Some Text");
    }

}

One place where a struct has been helpful for me is when I have a system that's receiving fixed format messages (over say, a serial port) from another system. You can cast the stream of bytes into a struct that defines your fields, and then easily access the fields.

typedef struct
{
    int messageId;
    int messageCounter;
    int messageData;
} tMessageType;

void processMessage(unsigned char *rawMessage)
{
    tMessageType *messageFields = (tMessageType *)rawMessage;
    printf("MessageId is %d\n", messageFields->messageId);
}

Obviously, this is the same thing you would do in C, but I find that the overhead of having to decode the message into a class is usually not worth it.

You just need to escape characters that have special meaning: # $ % & ~ _ ^ \ { }

So

http://stack_overflow.com/~foo%20bar#link

would be

http://stack\_overflow.com/\~foo\%20bar\#link

you are calling the context of not existing activity...so just replace your code in onClick(View v) as Intent intent=new Intent(this,Katra_home.class); startActivity(intent); it will definitely works....

// This code was tested by me (Helio Barbosa)

    // this directory (../backup) is for try only.
    // it is necessary create it and put files into him.

    $hDir = '../backup';
    if ($handle = opendir( $hDir )) {
        echo "Manipulador de diretório: $handle\n";
        echo "Arquivos:\n";

        /* Esta é a forma correta de varrer o diretório */
        /* Here is the correct form to do find files into the directory */
        while (false !== ($file = readdir($handle))) {
            // echo($file . "</br>");
            $filepath = $hDir . "/" . $file ;
            // echo( $filepath . "</br>" );
            if(is_file($filepath))
            {
                echo("Deleting:" . $file . "</br>");
                unlink($filepath);
            }           
        }

        closedir($handle);
    }

This is my method:

def is_square(n) -> bool:
    return int(n**0.5)**2 == int(n)

Take square root of number. Convert to integer. Take the square. If the numbers are equal, then it is a perfect square otherwise not.

It is incorrect for a large square such as 152415789666209426002111556165263283035677489.

If you are using a DbContext, you can do the following to get the SQL:

var result = from i in myContext.appEntities
             select new Model
             {
                 field = i.stuff,
             };
var sql = result.ToString();

Don't you need something to compare and then retrieve the milliseconds?

For instance:

let enteredDate = $("#txt-date").val(); // get the date entered in the input
let expires = moment.utc(enteredDate); // convert it into UTC

With that you have the expiring date in UTC. Now you can get the "right-now" date in UTC and compare:

var rightNowUTC = moment.utc(); // get this moment in UTC based on browser
let duration = moment.duration(rightNowUTC.diff(expires)); // get the diff
let remainingTimeInMls = duration.asMilliseconds();

You can use something like this:

RewriteEngine on
RewriteRule ^.+$ /index.php [L]

This will redirect every query to the root directory's index.php. Note that it will also redirect queries for files that exist, such as images, javascript files or style sheets.

Solved:

• Went on the log-in screen and clicked forgot my password.
• I entered my Google account email and I received a reset link.
• As you enter there a new password you'll have bitbucket id and password to use.

Sample:

git clone https://<bitbucket_id>@bitbucket.org/<repo>

You can pass a regex to the spec command which will only run it blocks matching the name you supply.

spec path/to/my_spec.rb -e "should be the correct answer"

2019 Update: Rspec2 switched from the 'spec' command to the 'rspec' command.

I answer to myself. As suggested by Vadzim, I must consider the jboss-logging.xml file and insert these lines:

<logger category="org.hibernate">
     <level name="TRACE"/>
</logger>

Instead of DEBUG level I wrote TRACE. Now don't look only the console but open the server.log file (debug messages aren't sent to the console but you can configure this mode!).

It's used for proxying requests to other servers.

An example from http://wiki.nginx.org/LoadBalanceExample is:

http {
  upstream myproject {
    server 127.0.0.1:8000 weight=3;
    server 127.0.0.1:8001;
    server 127.0.0.1:8002;    
    server 127.0.0.1:8003;
  }

  server {
    listen 80;
    server_name www.domain.com;
    location / {
      proxy_pass http://myproject;
    }
  }
}

This means all requests for / go to the any of the servers listed under upstream XXX, with a preference for port 8000.

Use document.activeElement, it is supported in all major browsers.

Previously, if you were trying to find out what form field has focus, you could not. To emulate detection within older browsers, add a "focus" event handler to all fields and record the last-focused field in a variable. Add a "blur" handler to clear the variable upon a blur event for the last-focused field.

If you need to remove the activeElement you can use blur; document.activeElement.blur(). It will change the activeElement to body.

• activeElement Browser Compatibility
• jQuery alternative for document.activeElement

It can be opened using Visual Studio 2012.Follow the below path in VS after opening the project. View->Server Explorer->

In Eclipse Photon you may need to add JUnit 4 or 5 to the build path. Right click @Test and select 'Add JUnit 4 to build path'.

Strings are immutable i.e if you change their value, the old value will be discarded and a new value is created on the heap, whereas in string builder we can modify the existing value without the new value being created.

So performance-wise String Builder is beneficial as we are needlessly not occupying more memory space.

Try:

Filter = "BMP|*.bmp|GIF|*.gif|JPG|*.jpg;*.jpeg|PNG|*.png|TIFF|*.tif;*.tiff"

Then do another round of copy/paste of all the extensions (joined together with ; as above) for "All graphics types":

Filter = "BMP|*.bmp|GIF|*.gif|JPG|*.jpg;*.jpeg|PNG|*.png|TIFF|*.tif;*.tiff|"
       + "All Graphics Types|*.bmp;*.jpg;*.jpeg;*.png;*.tif;*.tiff"

I'm using Assembly.GetExecutingAssembly().Location to get the path to a ClickOnce deployed application in .Net 4.5.1.

However, you shouldn't write to any folder where your application is deployed to ever, regardless of deployment method (xcopy, ClickOnce, InstallShield, anything) because those are usually read only for applications, especially in newer Windows versions and server environments.

An app must always write to the folders reserved for such purposes. You can get the folders you need starting from Environment.SpecialFolder Enumeration. The MSDN page explains what each folder is for: http://msdn.microsoft.com/en-us/library/system.environment.specialfolder.aspx

I.e. for data, logs and other files one can use ApplicationData (roaming), LocalApplicationData (local) or CommonApplicationData. For temporary files use Path.GetTempPath or Path.GetTempFileName.

The above work on servers and desktops too.

EDIT: Assembly.GetExecutingAssembly() is called in main executable.

I'm using Argos reporting system as a front end and Oracle in back. I just encountered this error and it was caused by a string with a double quote at the start and a single quote at the end. Replacing the double quote with a single solved the issue.

You can use the extension method AsEnumerable in Assembly System.Core and System.Linq namespace :

List<Book> list = new List<Book>();
return list.AsEnumerable();

This will, as said on this MSDN link change the type of the List in compile-time. This will give you the benefits also to only enumerate your collection we needed (see MSDN example for this).

Although CSS does provide a way for you to do the style specific to the checkbox type or another type, there are going to be problems with browsers that do not support this.

I think your only option in this case is going to be to apply classes to your checkboxes.

just add the class="checkbox" to your checkboxes.

Then create that style in your css code.

One thing you could do is this:

main.css

input[type="checkbox"] { /* css code here */ }

ie.css

.checkbox{ /* css code here for ie */ }

Then use the IE specific css include:

<!--[if lt IE 7]>
   <link rel="stylesheet" type="text/css" href="ie.css" />
<![endif]-->

You will still need to add the class for it to work in IE, and it will not work in other non-IE browsers that do not support IE. But it will make your website forward-thinking with css code and as IE gets support, you will be able to remove the ie specific css code and also the css classes from the checkboxes.

For really large numbers cycling or reducing could be process intensive. What about using Gauss?

sum = (n * (n+1))/2;

From mathcentral.

C:\test>find /c "string" file | find ": 0" 1>nul && echo "execute command here"

If you're behind a proxy, you should use X-Forwarded-For: http://en.wikipedia.org/wiki/X-Forwarded-For

It is an IETF draft standard with wide support:

The X-Forwarded-For field is supported by most proxy servers, including Squid, Apache mod_proxy, Pound, HAProxy, Varnish cache, IronPort Web Security Appliance, AVANU WebMux, ArrayNetworks, Radware's AppDirector and Alteon ADC, ADC-VX, and ADC-VA, F5 Big-IP, Blue Coat ProxySG, Cisco Cache Engine, McAfee Web Gateway, Phion Airlock, Finjan's Vital Security, NetApp NetCache, jetNEXUS, Crescendo Networks' Maestro, Web Adjuster and Websense Web Security Gateway.

If not, here are a couple other common headers I've seen:

• X-Client-IP (Apache)
• X-Real-IP (Nginx)

Add your style here:

You can turn on your PHP errors with error_reporting:

error_reporting(E_ALL);
ini_set('display_errors', 'on');

Edit: It's possible that even after putting this, errors still don't show up. This can be caused if there is a fatal error in the script. From PHP Runtime Configuration:

Although display_errors may be set at runtime (with ini_set()), it won't have any affect if the script has fatal errors. This is because the desired runtime action does not get executed.

You should set display_errors = 1 in your php.ini file and restart the server.

Just turn the LIKE around

SELECT * FROM customers
WHERE 'Robert Bob Smith III, PhD.' LIKE CONCAT('%',name,'%')

I was having the same problem while running bulk tests for an assignment. Turns out when I relocated some iostream operations (printing to console) from class constructor to a method in class it was solved.

I assume it was something to do with iostream manipulations in the constructor.

Here is the fix:

// Before
CommandPrompt::CommandPrompt() : afs(nullptr), aff(nullptr) {
    cout << "Some text I was printing.." << endl;

Please feel free to explain more what the error is behind the scenes since it goes beyond my cpp knowledge.

If you’re on SQL Server 2016-2017: to fix it, turn on trace flag 460

DBCC TRACEON(460, 1);

I have also been facing this error. None of the above methods work for me. Please follow this as it worked for me.

For Installing node-sass in Ubuntu 16 via npm :-

You can install with npm 5.2.0 Version

If you are using nvm :-

nvm install 8.2.1
nvm use 8.2.1
npm install node-sass

If you are using npm separately then upgrade or downgrade npm version to 5.2.0

npm install node-sass

In this case it is better to use basename instead of awk:

 $ basename /home/parent/child1/child2/filename
 filename

--launcher.XXMaxPermSize

256m

Try to bump that value up!

Here's a solution for the newest version of Bootstrap (4.3 at time of writing) using Flexbox.

HTML:

<div class="wrapper">
  <div class="content">
    <p>Content goes here</p>
  </div>
</div>
<footer class="footer"></footer>

CSS:

html, body {
  height: 100%;
}

body {
  display: flex;
  flex-direction: column;
}

.wrapper {
  flex-grow: 1;
}

And a codepen example: https://codepen.io/tillytoby/pen/QPdomR

<script>
  delete window.module;
</script>

before your jquery import and you're good to go. more info here.

I had colorama installed via pip and I was getting "ImportError: No module named colorama"

So I searched with "find", found the absolute path and added it in the script like this:

import sys
sys.path.append("/usr/local/lib/python3.8/dist-packages/")
import colorama 

And it worked.

Php will evaluate what you wrote between the [] brackets.

$foo = array('eins', 'zwei', 'apples', 'oranges');
var_dump($foo[3-1]);

Will produce string(6) "apples", because it returns $foo[2].

If you want that as a string, put inverted commas around it.

Make a toggle function in the respective scope to grey out the link.

First,create the following CSS classes in your .css file.

.disabled {
    pointer-events: none;
    cursor: default;
}

.enabled {
    pointer-events: visible;
    cursor: auto;
}

Add a $scope.state and $scope.toggle variable. Edit your controller in the JS file like:

    $scope.state='on';
    $scope.toggle='enabled';
    $scope.changeState = function () {
                $scope.state = $scope.state === 'on' ? 'off' : 'on';
                $scope.toggleEdit();
            };
    $scope.toggleEdit = function () {
            if ($scope.state === 'on')
                $scope.toggle = 'enabled';
            else
                $scope.toggle = 'disabled';
        };

Now,in the HTML a tags edit as:

<a href="#" ng-click="create()" class="{{toggle}}">CREATE</a><br/>
<a href="#" ng-click="edit()" class="{{toggle}}">EDIT</a><br/>
<a href="#" ng-click="delete()" class="{{toggle}}">DELETE</a>

To avoid the problem of the link disabling itself, change the DOM CSS class at the end of the function.

document.getElementById("create").className = "enabled";

With JDK/12 early access build # 12, one can now use multiline strings in Java as follows :

String multiLine = `First line
    Second line with indentation
Third line
and so on...`; // the formatting as desired
System.out.println(multiLine);

and this results in the following output:

First line
    Second line with indentation
Third line
and so on...

Edit: Postponed to java 13

It is a good practice to create helper utility methods for things like that so that whenever you need to change the logic of attribute validation it would be in one place, and the code will be more readable for the followers.

For example create a helper method (or class JsonUtils with static methods) in json_utils.py:

def get_attribute(data, attribute, default_value):
    return data.get(attribute) or default_value

and then use it in your project:

from json_utils import get_attribute

def my_cool_iteration_func(data):

    data_to = get_attribute(data, 'to', None)
    if not data_to:
        return

    data_to_data = get_attribute(data_to, 'data', [])
    for item in data_to_data:
        print('The id is: %s' % get_attribute(item, 'id', 'null'))

IMPORTANT NOTE:

There is a reason I am using data.get(attribute) or default_value instead of simply data.get(attribute, default_value):

{'my_key': None}.get('my_key', 'nothing') # returns None
{'my_key': None}.get('my_key') or 'nothing' # returns 'nothing'

In my applications getting attribute with value 'null' is the same as not getting the attribute at all. If your usage is different, you need to change this.

# Json to object
$obj = $obj | ConvertFrom-Json
Write-host $obj.PropertyName

Assuming the objects in your source array have an id property...

var $local_source = [
    { id: 1, value: "c++" },
    { id: 2, value: "java" },
    { id: 3, value: "php" },
    { id: 4, value: "coldfusion" },
    { id: 5, value: "javascript" },
    { id: 6, value: "asp" },
    { id: 7, value: "ruby" }];

Getting hold of the current instance and inspecting its selectedItem property will allow you to retrieve the properties of the currently selceted item. In this case alerting the id of the selected item.

$('#button').click(function() {
    alert($("#txtAllowSearch").autocomplete("instance").selectedItem.id;
});

If the databases share server, have a login that has priveleges to both of the databases, and simply have a query run similiar to:

$query = $this->db->query("
SELECT t1.*, t2.id
FROM `database1`.`table1` AS t1, `database2`.`table2` AS t2
");

Otherwise I think you might have to run the 2 queries separately and fix the logic afterwards.

Assume that you have the list of ALL keys (you can get this list by iterating through all dictionaries and get their keys). Let's name it listKeys. Also:

• listValues is the list of ALL values for a single key that you want to merge.
• allDicts: all dictionaries that you want to merge.

result = {}
for k in listKeys:
    listValues = [] #we will convert it to tuple later, if you want.
    for d in allDicts:
       try:
            fileList.append(d[k]) #try to append more values to a single key
        except:
            pass
    if listValues: #if it is not empty
        result[k] = typle(listValues) #convert to tuple, add to new dictionary with key k

Move

Random pp = new Random();
int a1 = pp.nextInt(10);
TextView tv = (TextView)findViewById(R.id.tv);
tv.setText(a1);

To inside onCreate(), and change tv.setText(a1); to tv.setText(String.valueOf(a1)); :

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

  Random pp = new Random();
  int a1 = pp.nextInt(10);

  TextView tv = (TextView)findViewById(R.id.tv);
  tv.setText(String.valueOf(a1));

}   

First issue: findViewById() was called before onCreate(), which would throw an NPE.

Second issue: Passing an int directly to a TextView calls the overloaded method that looks for a String resource (from R.string). Therefore, we want to use String.valueOf() to force the String overloaded method.

After upgrade Mac OS to Mojave. I tried to install npm modules via yarn command I got error:

dyld: Library not loaded: /usr/local/opt/icu4c/lib/libicui18n.60.dylib
  Referenced from: /usr/local/bin/node
  Reason: image not found
Abort trap: 6

Was fixed with:

brew update
brew upgrade

This works fine

@echo off    
set word=table    
set str=jump over the chair    
set rpl=%str:chair=%%word%    
echo %rpl%

display:none is the best thing to avoid takeup white space on the page

I have found... margin: 0 auto; works for me. But I have also seen it NOT work due to the class being trumped by another specificity that had ... float:left; so watch for that you may need to add ... float:none; this worked in my case as I was coding a media query.

This is how I've always done it:

<ItemTemplate>
  <%# Boolean.Parse(Eval("Active").ToString()) ? "Yes" : "No" %>
</ItemTemplate>

Hope that helps.

Pointers

• A pointer is a variable that holds a memory address.
• A pointer declaration consists of a base type, an *, and the variable name.
• A pointer can point to any number of variables in lifetime

• A pointer that does not currently point to a valid memory location is given the value null (Which is zero)

  BaseType* ptrBaseType;
  BaseType objBaseType;
  ptrBaseType = &objBaseType;
  

• The & is a unary operator that returns the memory address of its operand.

• Dereferencing operator (*) is used to access the value stored in the variable which pointer points to.

     int nVar = 7;
     int* ptrVar = &nVar;
     int nVar2 = *ptrVar;
  

Reference

• A reference (&) is like an alias to an existing variable.

• A reference (&) is like a constant pointer that is automatically dereferenced.

• It is usually used for function argument lists and function return values.

• A reference must be initialized when it is created.

• Once a reference is initialized to an object, it cannot be changed to refer to another object.

• You cannot have NULL references.

• A const reference can refer to a const int. It is done with a temporary variable with value of the const

  int i = 3;    //integer declaration
  int * pi = &i;    //pi points to the integer i
  int& ri = i;    //ri is refers to integer i – creation of reference and initialization
  

Importing the namespace is somewhat cleaner. Imagine you have two different modules you import, both of them with the same method/class. Some bad stuff might happen. I'd dare say it is usually good practice to use:

import module

over

from module import function/class

Basic on @Horyun Lee answer, I wrote a small python script to help to investigate ANR from traces.txt.

The ANRs will output as graphics by graphviz if you have installed grapvhviz on your system.

$ ./anr.py --format png ./traces.txt

A png will output like below if there are ANRs detected in file traces.txt. It's more intuitive.

The sample traces.txt file used above was get from here.

Try this

        self.opener.location.reload();

I've upload file using reference. No package is required to upload file this way.

// code to be written in .ts file

For saving the original stdout and stderr you can use:

exec [fd number]<&1 
exec [fd number]<&2

For example, the following code will print "walla1" and "walla2" to the log file (a.txt), "walla3" to stdout, "walla4" to stderr.

#!/bin/bash

exec 5<&1
exec 6<&2

exec 1> ~/a.txt 2>&1

echo "walla1"
echo "walla2" >&2
echo "walla3" >&5
echo "walla4" >&6

As the error says, you need to make sure that your sql server is running and listening on port 1433. If server is running then you need to check whether there is some firewall rule rejecting the connection on port 1433.

Here are the commands that can be useful to troubleshoot:

1. Use netstat -a to check whether sql server is listening on the desired port
2. As gerrytan mentioned in answer, you can try to do the telnet on the host and port

Use getBBox function

Use:

window.location = "http://my.url.here";

Here's some quick-n-dirty code that uses jQuery to do what you want. I highly recommend using jQuery. It'll make things a lot more easier for you, especially since you're new to JavaScript.

<select id = "pricingOptions" name = "pricingOptions">
    <option value = "500">Option A</option>
    <option value = "1000">Option B</option>
</select>

<script type = "text/javascript" language = "javascript">
    jQuery(document).ready(function() {
        jQuery("#pricingOptions").change(function() {
            if(this.options[this.selectedIndex].value == "500") {
                window.location = "http://example.com/foo.php?option=500";
            }
        });
    });
</script>

I'm debugging an issue I'm having with SSL connecting to a database (MySQL RDS) using an ORM called, Prisma. The database connection string requires a PKCS12 (.p12) file (if interested, described here), which brought me here.

I know the question has been answered, but I found the following steps (in Github Issue#2676) to be helpful for creating a .p12 file and wanted to share. Good luck!

1. Generate 2048-bit RSA private key:

   openssl genrsa -out key.pem 2048

2. Generate a Certificate Signing Request:

   openssl req -new -sha256 -key key.pem -out csr.csr

3. Generate a self-signed x509 certificate suitable for use on web servers.

   openssl req -x509 -sha256 -days 365 -key key.pem -in csr.csr -out certificate.pem

4. Create SSL identity file in PKCS12 as mentioned here

   openssl pkcs12 -export -out client-identity.p12 -inkey key.pem -in certificate.pem

This worked for me on Swift 5

Fontinator is an Android-Library make it easy, to use custom Fonts. https://github.com/svendvd/Fontinator

One could use the Buffers that are provided as part of the java.nio package to perform the conversion.

Here, the source byte[] array has a of length 8, which is the size that corresponds with a long value.

First, the byte[] array is wrapped in a ByteBuffer, and then the ByteBuffer.getLong method is called to obtain the long value:

ByteBuffer bb = ByteBuffer.wrap(new byte[] {0, 0, 0, 0, 0, 0, 0, 4});
long l = bb.getLong();

System.out.println(l);

Result

4

I'd like to thank dfa for pointing out the ByteBuffer.getLong method in the comments.

Although it may not be applicable in this situation, the beauty of the Buffers come with looking at an array with multiple values.

For example, if we had a 8 byte array, and we wanted to view it as two int values, we could wrap the byte[] array in an ByteBuffer, which is viewed as a IntBuffer and obtain the values by IntBuffer.get:

ByteBuffer bb = ByteBuffer.wrap(new byte[] {0, 0, 0, 1, 0, 0, 0, 4});
IntBuffer ib = bb.asIntBuffer();
int i0 = ib.get(0);
int i1 = ib.get(1);

System.out.println(i0);
System.out.println(i1);

Result:

1
4

You can add a click event handler for this:

document.getElementById('button').onclick = function() {
   alert("button was clicked");
}?;?

This will alert when it's clicked, if you want to track it for later, just set a variable to true in that function instead of alerting, or variable++ if you want to count the number of clicks, whatever your ultimate use is. You can see an example here.

Just in case you are using Boostrap in Angulajs: this is a simple directive that works for me (because data-toggle cited by Kam is not included in Angular-ui). Hope can help.

app.directive("myDataToggle", function(){
    function link(scope, element, attrs) {
        var e = angular.element(element);
        e.on('click', function(){
            e.parent().parent().children().removeClass('active');
            e.parent().addClass("active");
        })
    }
    return {
        restrict: 'A',
        link: link
    };
});

<ul class="nav nav-sidebar">
    <li><a href="#/page1" my-data-toggle>Page1</a></li>

    <li><a href="#/page3" my-data-toggle>Page3</a></li>
</ul>

As ams said above, don't take a pointer to a member of a struct that's packed. This is simply playing with fire. When you say __attribute__((__packed__)) or #pragma pack(1), what you're really saying is "Hey gcc, I really know what I'm doing." When it turns out that you do not, you can't rightly blame the compiler.

Perhaps we can blame the compiler for it's complacency though. While gcc does have a -Wcast-align option, it isn't enabled by default nor with -Wall or -Wextra. This is apparently due to gcc developers considering this type of code to be a brain-dead "abomination" unworthy of addressing -- understandable disdain, but it doesn't help when an inexperienced programmer bumbles into it.

Consider the following:

struct  __attribute__((__packed__)) my_struct {
    char c;
    int i;
};

struct my_struct a = {'a', 123};
struct my_struct *b = &a;
int c = a.i;
int d = b->i;
int *e __attribute__((aligned(1))) = &a.i;
int *f = &a.i;

Here, the type of a is a packed struct (as defined above). Similarly, b is a pointer to a packed struct. The type of of the expression a.i is (basically) an int l-value with 1 byte alignment. c and d are both normal ints. When reading a.i, the compiler generates code for unaligned access. When you read b->i, b's type still knows it's packed, so no problem their either. e is a pointer to a one-byte-aligned int, so the compiler knows how to dereference that correctly as well. But when you make the assignment f = &a.i, you are storing the value of an unaligned int pointer in an aligned int pointer variable -- that's where you went wrong. And I agree, gcc should have this warning enabled by default (not even in -Wall or -Wextra).

Using Encoding.Unicode won't accurately decode an ANSI file in the same way that a JPEG decoder won't understand a GIF file.

I'm surprised that Encoding.Default didn't work for the ANSI file if it really was ANSI - if you ever find out exactly which code page Notepad was using, you could use Encoding.GetEncoding(int).

In general, where possible I'd recommend using UTF-8.

    background-image: url(your image link);

It doesn't seem like anyone so far has addressed the actual problem with your original code, so I thought I would do that even though the question is quite old at this point.

The problem originally had to do with the projection in relation to the radius and position of the sphere. I think you'll find that the problem isn't too complicated. The program actually works correctly, it's just that what is being drawn is very hard to see.

First, an orthogonal projection was created using the call

gluOrtho2D(0.0, 499.0, 0.0, 499.0);

which "is equivalent to calling glOrtho with near = -1 and far = 1." This means that the viewing frustum has a depth of 2. So a sphere with a radius of anything greater than 1 (diameter = 2) will not fit entirely within the viewing frustum.

Then the calls

glLoadIdentity();
glutSolidSphere(5.0, 20.0, 20.0);

are used, which loads the identity matrix of the model-view matrix and then "[r]enders a sphere centered at the modeling coordinates origin of the specified radius." Meaning, the sphere is rendered at the origin, (x, y, z) = (0, 0, 0), and with a radius of 5.

Now, the issue is three-fold:

1. Since the window is 500x500 pixels and the width and height of the viewing frustum is almost 500 (499.0), the small radius of the sphere (5.0) makes its projected area only slightly over one fiftieth (2*5/499) of the size of the window in each dimension. This means that the apparent size of the sphere would be roughly 1/2,500th (actually pi*5^2/499^2, which is closer to about 1/3170th) of the entire window, so it might be difficult to see. This is assuming the entire circle is drawn within the area of the window. It is not, however, as we will see in point 2.
2. Since the viewing frustum has it's left plane at x = 0 and bottom plane at y = 0, the sphere will be rendered with its geometric center in the very bottom left corner of the window so that only one quadrant of the projected sphere will be visible! This means that what would be seen is even smaller, about 1/10,000th (actually pi*5^2/(4*499^2), which is closer to 1/12,682nd) of the window size. This would make it even more difficult to see. Especially since the sphere is rendered so close to the edges/corner of the screen where you might not think to look.
3. Since the depth of the viewing frustum is significantly smaller than the diameter of the sphere (less than half), only a sliver of the sphere will be within the viewing frustum, rendering only that part. So you will get more like a hollow circle on the screen than a solid sphere/circle. As it happens, the thickness of that sliver might represent less than 1 pixel on the screen which means we might even see nothing on the screen, even if part of the sphere is indeed within the viewing frustum.

The solution is simply to change the viewing frustum and radius of the sphere. For instance,

gluOrtho2D(-5.0, 5.0, -5.0, 5.0);
glutSolidSphere(5.0, 20, 20);

renders the following image.

As you can see, only a small part is visible around the "equator", of the sphere with a radius of 5. (I changed the projection to fill the window with the sphere.) Another example,

gluOrtho2D(-1.1, 1.1, -1.1, 1.1);
glutSolidSphere(1.1, 20, 20);

renders the following image.

The image above shows more of the sphere inside of the viewing frustum, but still the sphere is 0.2 depth units larger than the viewing frustum. As you can see, the "ice caps" of the sphere are missing, both the north and the south. So, if we want the entire sphere to fit within the viewing frustum which has depth 2, we must make the radius less than or equal to 1.

gluOrtho2D(-1.0, 1.0, -1.0, 1.0);
glutSolidSphere(1.0, 20, 20);

renders the following image.

I hope this has helped someone. Take care!

"One last remark: you should avoid using Task.Result and Task.Wait as much as possible as they always encapsulate the inner exception in an AggregateException and replace the message by a generic one (One or more errors occurred), which makes debugging harder. Even if the synchronous version shouldn't be used that often, you should strongly consider using Task.GetAwaiter().GetResult() instead."

I've run into this as well, solution is usually to be sure to run the program as an administrator (right click, run as administrator.)

This works for both Chrome and Firefox.
Not tested on other browsers.

      // convert to 2021-02-21T04:01:19.000000Z format before convert to local time
      const splited = dateTime.split(" ");
      let convertedDateTime = `${splited[0]}T${splited[1]}.000000Z`;
      const date = new Date(convertedDateTime);
      return date.toString();
    } else {

I have solved it with Dov Benjamin's help like that:

And another method, for both V1.x and 2.x of vue.js

Vue 1:

<p v-for="item in items | limitBy 10">{{ item }}</p>

Vue2:
