This will also work:

<Hyperlink Command="{Binding RelativeSource={RelativeSource AncestorType=ItemsControl},
                             Path=DataContext.AllowItemCommand}" />

ListView will inherit its DataContext from Window, so it's available at this point, too.
And since ListView, just like similar controls (e. g. Gridview, ListBox, etc.), is a subclass of ItemsControl, the Binding for such controls will work perfectly.

You can copy by inspect element and target the div you want to copy. Just press ctrl+c and then your div will be copy and paste in your code it will run easily.

As far as I know there is no “native” PowerShell way of getting this information. And perhaps it is rather the .NET limitation than PowerShell.

Here is the suggestion to add this functionality to the version next:

The WMI workaround is also there, just in case. I use this WMI solution for my tasks and it works.

Just ran into this problem. All I had to do is uninstall mysql2 gem and reinstall it. Hope this works for other people

LENGTH() returns the length of the string measured in bytes.
CHAR_LENGTH() returns the length of the string measured in characters.

This is especially relevant for Unicode, in which most characters are encoded in two bytes. Or UTF-8, where the number of bytes varies. For example:

select length(_utf8 '€'), char_length(_utf8 '€')
--> 3, 1

As you can see the Euro sign occupies 3 bytes (it's encoded as 0xE282AC in UTF-8) even though it's only one character.

There IS A POINT in introducing MAX_FILE_SIZE client side hidden form field.

php.ini can limit uploaded file size. So, while your script honors the limit imposed by php.ini, different HTML forms can further limit an uploaded file size. So, when uploading video, form may limit* maximum size to 10MB, and while uploading photos, forms may put a limit of just 1mb. And at the same time, the maximum limit can be set in php.ini to suppose 10mb to allow all this.

Although this is not a fool proof way of telling the server what to do, yet it can be helpful.

• HTML does'nt limit anything. It just forwards the server all form variable including MAX_FILE_SIZE and its value.

Hope it helped someone.

If order matters, you should keep a property on the "T" objects in your list that denotes sequence. In order to swap them, just swap the value of that property, and then use that in the .Sort(comparison with sequence property)

UPDATE: I suggest using a solution with filters, provided by @Jess.

I would write a method for that, and then where you need to format price you can just put the method in the template and pass value down

methods: {
    formatPrice(value) {
        let val = (value/1).toFixed(2).replace('.', ',')
        return val.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ".")
    }
}

And then in template:

<template>
    <div>
        <div class="panel-group"v-for="item in list">
            <div class="col-md-8">
                <small>
                   Total: <b>{{ formatPrice(item.total) }}</b>
                </small>
            </div>
        </div>
    </div>
</template>

BTW - I didn't put too much care on replacing and regular expression. It could be improved.enter code here

Vue.filter('tableCurrency', num => {_x000D_
  if (!num) {_x000D_
    return '0.00';_x000D_
  }_x000D_
  const number = (num / 1).toFixed(2).replace(',', '.');_x000D_
  return number.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ',');_x000D_
});

Seems that EditText apply the hintTextColor only if the text is empty. So simple solution will be like this

Editable text = mEditText.getText();
mEditText.setText(null);
mEditText.setHintTextColor(color);
mEditText.setText(text);

If you have multiple fields, you can extend the EditText and write a method which executes this logic and use that method instead.

You just need to put the ngModel and the value you want selected:

<select id="typeUser" ngModel="Advanced" name="typeUser">
  <option>Basic</option>
  <option>Advanced</option>
  <option>Pro</option>
</select>

Yes, it is possible. You might also want to define __all__ in __init__.py files. It's a list of modules that will be imported when you do

from lib import *

@user187291 code works and only fails when + is not encoded.

I know this is very old post. But this worked to me.

$is_encoded = preg_match('~%[0-9A-F]{2}~i', $string);
if($is_encoded) {
 $string  = urlencode(urldecode(str_replace(['+','='], ['%2B','%3D'], $string)));
} else {
  $string = urlencode($string);
}

Video file example (HTML + Javascript):

function upload_check()
{
    var upl = document.getElementById("file_id");
    var max = document.getElementById("max_id").value;

    if(upl.files[0].size > max)
    {
       alert("File too big!");
       upl.value = "";
    }
};

<form action="some_script" method="post" enctype="multipart/form-data">
    <input id="max_id" type="hidden" name="MAX_FILE_SIZE" value="250000000" />
    <input onchange="upload_check()" id="file_id" type="file" name="file_name" accept="video/*" />
    <input type="submit" value="Upload"/>
</form>

Saw this in a comment and I thought it was the simplest explanation.

filter(A, B) is the AND filter(A).filter(B) is OR

Although I am very late to this but after seeing some legitimate questions for those who wanted to use INSERT-SELECT query with GROUP BY clause, I came up with the work around for this.

Taking further the answer of Marcus Adams and accounting GROUP BY in it, this is how I would solve the problem by using Subqueries in the FROM Clause

INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, 
                inact, inadur, inadist, 
                smlct, smldur, smldist, 
                larct, lardur, lardist, 
                emptyct, emptydur)
SELECT sb.id, uid, sb.location, sb.animal, sb.starttime, sb.endtime, sb.entct, 
       sb.inact, sb.inadur, sb.inadist, 
       sb.smlct, sb.smldur, sb.smldist, 
       sb.larct, sb.lardur, sb.lardist, 
       sb.emptyct, sb.emptydur
FROM
(SELECT id, uid, location, animal, starttime, endtime, entct, 
       inact, inadur, inadist, 
       smlct, smldur, smldist, 
       larct, lardur, lardist, 
       emptyct, emptydur 
FROM tmp WHERE uid=x
GROUP BY location) as sb
ON DUPLICATE KEY UPDATE entct=sb.entct, inact=sb.inact, ...

The following worked for me: https://github.com/microsoft/TypeScript/issues/28631#issuecomment-472606019 I fix it by doing something like this:

const Component = (isFoo ? FooComponent : BarComponent) as React.ElementType

This is really easy: Example

//my object
var sendData = {field1:value1, field2:value2};

//add element
sendData['field3'] = value3;

In my case the problem was introduced when I fixed a static analysis error that the return value of a method was not used.

Old working code in my Application.java was:

    public static void main(String[] args) {        
      SpringApplication.run(Application.class, args);
    }

New code that introduced the problem was:

    public static void main(String[] args) {        
      try (ConfigurableApplicationContext context = 
          SpringApplication.run(Application.class, args)) {
        LOG.trace("context: " + context);
      }
    }

Obviously, the try with resource block will close the context after starting the application which will result in the application exiting with status 0. This was a case where the resource leak error reported by snarqube static analysis should be ignored.

Here are simple steps that minimize tedium and don't require error-prone semi-automated scripts or pricey tools.

Keep in mind that you can generate DROP/CREATE statements for multiple objects from the Object Explorer Details window (when generated this way, DROP and CREATE scripts are grouped, which makes it easy to insert logic between Drop and Create actions):

1. Back up you database in case anything goes wrong!
2. Automatically generate the DROP/CREATE statements for all dependencies (or generate for all "Programmability" objects to eliminate the tedium of finding dependencies).
3. Between the DROP and CREATE [dependencies] statements (after all DROP, before all CREATE), insert generated DROP/CREATE [table type] statements, making the changes you need with CREATE TYPE.
4. Run the script, which drops all dependencies/UDTTs and then recreates [UDTTs with alterations]/dependencies.

If you have smaller projects where it might make sense to change the infrastructure architecture, consider eliminating user-defined table types. Entity Framework and similar tools allow you to move most, if not all, of your data logic to your code base where it's easier to maintain.

If you are importing or you have an array (of type string) in your code and you have to convert it into arraylist (offcourse string) then use of collections is better. like this:

String array1[] = getIntent().getExtras().getStringArray("key1"); or String array1[] = ... then

List allEds = new ArrayList(); Collections.addAll(allEds, array1);

If you want it to display the content of the file live, and update when the file is altered, just use this script:

@echo off
:start
cls
type myfile.txt
goto start

That will repeat forever until you close the cmd window.

The solutions posted so far only deal with part of the problem, converting DOS/Windows' CRLF into Unix's LF; the part they're missing is that DOS use CRLF as a line separator, while Unix uses LF as a line terminator. The difference is that a DOS file (usually) won't have anything after the last line in the file, while Unix will. To do the conversion properly, you need to add that final LF (unless the file is zero-length, i.e. has no lines in it at all). My favorite incantation for this (with a little added logic to handle Mac-style CR-separated files, and not molest files that're already in unix format) is a bit of perl:

perl -pe 'if ( s/\r\n?/\n/g ) { $f=1 }; if ( $f || ! $m ) { s/([^\n])\z/$1\n/ }; $m=1' PCfile.txt

Note that this sends the Unixified version of the file to stdout. If you want to replace the file with a Unixified version, add perl's -i flag.

Answer from 2021 in kotlin

Encode :

        val data: String = "Hello"
        val dataByteArray: ByteArray = data.toByteArray()
        val dataInBase64: String = Base64Utils.encode(dataByteArray)

Decode :

        val dataInBase64: String = "..."
        val dataByteArray: ByteArray = Base64Utils.decode(dataInBase64)
        val data: String = dataByteArray.toString()

You need single quotes around the view name

{% url 'viewname' %}

instead of

{% url viewname %}

It is possible to extend the relation with query functions:

<?php
public function comments()
{
    return $this->hasMany('Comment')->orderBy('column');
}

[edit after comment]

<?php
class User
{
    public function comments()
    {
        return $this->hasMany('Comment');
    }
}

class Controller
{
    public function index()
    {
        $column = Input::get('orderBy', 'defaultColumn');
        $comments = User::find(1)->comments()->orderBy($column)->get();

        // use $comments in the template
    }
}

default User model + simple Controller example; when getting the list of comments, just apply the orderBy() based on Input::get(). (be sure to do some input-checking ;) )

In my case, I forgot to add my IP address in firewall rules in Azure, basically as I was unable to connect to the database I was getting this error. So specifically for my case, I added my IP address in database firewall rules in Azure and it all worked well. Apart from this, it could be the issue of proxy/internet connection/DB username password/DB connection string etc. OR obviously, you might have pending migrations for which you need to run Update-Database command.

You can select the columns of a groupby:

In [11]: df.groupby(['Country', 'Item_Code'])[["Y1961", "Y1962", "Y1963"]].sum()
Out[11]:
                       Y1961  Y1962  Y1963
Country     Item_Code
Afghanistan 15            10     20     30
            25            10     20     30
Angola      15            30     40     50
            25            30     40     50

Note that the list passed must be a subset of the columns otherwise you'll see a KeyError.

You need to go throgh these scenario:

How about using display:inline-block?

1) Take one <div/> give it style=display:inline-block make it vertical-align:top and put image inside that div.

2) Take another div and give it also the same style display:inline-block; and put all the labels/divs inside this div.

Here is the prototype of your requirement

JS Fiddle Demo

Thank you Phil for your solution; in case someone ever gets in the same situation as me, here is a (more complex) variant:

---
# this is just to avoid a call to |default on each iteration
- set_fact:
    postconf_d: {}

- name: 'get postfix default configuration'
  command: 'postconf -d'
  register: command

# the answer of the command give a list of lines such as:
# "key = value" or "key =" when the value is null
- name: 'set postfix default configuration as fact'
  set_fact:
    postconf_d: >
      {{
        postconf_d |
        combine(
          dict([ item.partition('=')[::2]|map('trim') ])
        )
  with_items: command.stdout_lines

This will give the following output (stripped for the example):

"postconf_d": {
    "alias_database": "hash:/etc/aliases", 
    "alias_maps": "hash:/etc/aliases, nis:mail.aliases",
    "allow_min_user": "no", 
    "allow_percent_hack": "yes"
}

Going even further, parse the lists in the 'value':

- name: 'set postfix default configuration as fact'
  set_fact:
    postconf_d: >-
      {% set key, val = item.partition('=')[::2]|map('trim') -%}
      {% if ',' in val -%}
        {% set val = val.split(',')|map('trim')|list -%}
      {% endif -%}
      {{ postfix_default_main_cf | combine({key: val}) }}
  with_items: command.stdout_lines
...

"postconf_d": {
    "alias_database": "hash:/etc/aliases", 
    "alias_maps": [
        "hash:/etc/aliases", 
        "nis:mail.aliases"
    ], 
    "allow_min_user": "no", 
    "allow_percent_hack": "yes"
}

A few things to notice:

• in this case it's needed to "trim" everything (using the >- in YAML and -%} in Jinja), otherwise you'll get an error like:

  FAILED! => {"failed": true, "msg": "|combine expects dictionaries, got u\"  {u'...
  

• obviously the {% if .. is far from bullet-proof

• in the postfix case, val.split(',')|map('trim')|list could have been simplified to val.split(', '), but I wanted to point out the fact you will need to |list otherwise you'll get an error like:

  "|combine expects dictionaries, got u\"{u'...': <generator object do_map at ...
  

Hope this can help.

Memcached client library was just recently released as stable. It is being used by digg ( was developed for digg by Andrei Zmievski, now no longer with digg) and implements much more of the memcached protocol than the older memcache client. The most important features that memcached has are:

1. Cas tokens. This made my life much easier and is an easy preventive system for stale data. Whenever you pull something from the cache, you can receive with it a cas token (a double number). You can than use that token to save your updated object. If no one else updated the value while your thread was running, the swap will succeed. Otherwise a newer cas token was created and you are forced to reload the data and save it again with the new token.
2. Read through callbacks are the best thing since sliced bread. It has simplified much of my code.
3. getDelayed() is a nice feature that can reduce the time your script has to wait for the results to come back from the server.
4. While the memcached server is supposed to be very stable, it is not the fastest. You can use binary protocol instead of ASCII with the newer client.
5. Whenever you save complex data into memcached the client used to always do serialization of the value (which is slow), but now with memcached client you have the option of using igbinary. So far I haven't had the chance to test how much of a performance gain this can be.

All of this points were enough for me to switch to the newest client, and can tell you that it works like a charm. There is that external dependency on the libmemcached library, but have managed to install it nonetheless on Ubuntu and Mac OSX, so no problems there so far.

If you decide to update to the newer library, I suggest you update to the latest server version as well as it has some nice features as well. You will need to install libevent for it to compile, but on Ubuntu it wasn't much trouble.

I haven't seen any frameworks pick up the new memcached client thus far (although I don't keep track of them), but I presume Zend will get on board shortly.

UPDATE

Zend Framework 2 has an adapter for Memcached which can be found here

to do it we have to know the three components

1. the place responsible for firing the Event
2. the place responsible for responding to the Event

3. the Event itself

   a. Event

   b .EventArgs

   c. EventArgs enumeration

now lets create Event that fired when a function is called

but I my order of solving this problem like this: I'm using the class before I create it

1. the place responsible for responding to the Event

   NetLog.OnMessageFired += delegate(object o, MessageEventArgs args) 
   {
           // when the Event Happened I want to Update the UI
           // this is WPF Window (WPF Project)  
           this.Dispatcher.Invoke(() =>
           {
               LabelFileName.Content = args.ItemUri;
               LabelOperation.Content = args.Operation;
               LabelStatus.Content = args.Status;
           });
   };
   

NetLog is a static class I will Explain it later

the next step is

2. the place responsible for firing the Event

   //this is the sender object, MessageEventArgs Is a class I want to create it  and Operation and Status are Event enums
   NetLog.FireMessage(this, new MessageEventArgs("File1.txt", Operation.Download, Status.Started));
   downloadFile = service.DownloadFile(item.Uri);
   NetLog.FireMessage(this, new MessageEventArgs("File1.txt", Operation.Download, Status.Finished));
   

the third step

3. the Event itself

I warped The Event within a class called NetLog

public sealed class NetLog
{
    public delegate void MessageEventHandler(object sender, MessageEventArgs args);

    public static event MessageEventHandler OnMessageFired;
    public static void FireMessage(Object obj,MessageEventArgs eventArgs)
    {
        if (OnMessageFired != null)
        {
            OnMessageFired(obj, eventArgs);
        }
    }
}

public class MessageEventArgs : EventArgs
{
    public string ItemUri { get; private set; }
    public Operation Operation { get; private set; }
    public Status Status { get; private set; }

    public MessageEventArgs(string itemUri, Operation operation, Status status)
    {
        ItemUri = itemUri;
        Operation = operation;
        Status = status;
    }
}

public enum Operation
{
    Upload,Download
}

public enum Status
{
    Started,Finished
}

this class now contain the Event, EventArgs and EventArgs Enums and the function responsible for firing the event

sorry for this long answer

Yes, you can switch on the name...

switch (obj.GetType().Name)
{
    case "TextBox":...
}

Mine is similar to your solution but I got it to work. Only difference is my model. I have the following models in my html input:

ng-model="new.Participant.email"
ng-model="new.Participant.confirmEmail"

and in my controller, I have this in $scope:

 $scope.new = {
        Participant: {}
    };

and this validation line worked:

<label class="help-block" ng-show="new.Participant.email !== new.Participant.confirmEmail">Emails must match! </label>

just to add some clarity, you need to stage changes with git add, then amend last commit:

git add /path/to/modified/files
git commit --amend --no-edit

This is especially useful for if you forgot to add some changes in last commit or when you want to add more changes without creating new commits by reusing the last commit.

I seem to struggle with this (and many other unintuitive things) every time I use PowerShell after time away from it, so I now opt for:

[string]::Concat("There are ", $count, " items in the list")

I know it was asked over 6 years ago, but knowledge is still knowledge. This is different solution than all above, as I had to run it under SQL Server 2000:

DECLARE @TestData TABLE([ID] int, [SKU] char(6), [Product] varchar(15))
INSERT INTO @TestData values (1 ,'FOO-23', 'Orange')
INSERT INTO @TestData values (2 ,'BAR-23', 'Orange')
INSERT INTO @TestData values (3 ,'FOO-24', 'Apple')
INSERT INTO @TestData values (4 ,'FOO-25', 'Orange')

SELECT DISTINCT  [ID] = ( SELECT TOP 1 [ID]  FROM @TestData Y WHERE Y.[Product] = X.[Product])
                ,[SKU]= ( SELECT TOP 1 [SKU] FROM @TestData Y WHERE Y.[Product] = X.[Product])
                ,[PRODUCT] 
            FROM @TestData X  

You can even avoid the function at the parent updating the state directly

In Parent Component:

render(){
 return(<Child sendData={ v => this.setState({item: v}) } />);
}

In the Child Component:

demoMethod(){
   this.props.sendData(value);
}

Use the name of the base class in an initializer-list. The initializer-list appears after the constructor signature before the method body and can be used to initialize base classes and members.

class Base
{
public:
  Base(char* name)
  {
     // ...
  }
};

class Derived : Base
{
public:
  Derived()
    : Base("hello")
  {
      // ...
  }
};

Or, a pattern used by some people is to define 'super' or 'base' yourself. Perhaps some of the people who favour this technique are Java developers who are moving to C++.

class Derived : Base
{
public:
  typedef Base super;
  Derived()
    : super("hello")
  {
      // ...
  }
};

I had a similar issue, and to quote Sherlock Holmes: "when you have eliminated the impossible, whatever remains, however improbable, must be the truth?"

I checked if the .NET framework I was targeting was installed on the server, and it turns out it wasn't. I installed the 4.6.2 .NET Framework and it worked.

I landed here because of an XCTestCase, in which I'd disabled most of the tests by prefixing them with 'no_' as in no_testBackgroundAdding. Once I noticed that most of the answers had something to do with locks and threading, I realized the test contained a few instances of XCTestExpectation with corresponding waitForExpectations. They were all in the disabled tests, but apparently Xcode was still evaluating them at some level.

In the end I found an XCTestExpectation that was defined as @property but lacked the @synthesize. Once I added the synthesize directive, the EXC_BAD_INSTRUCTION disappeared.

You have to escape the quotationmark:

printf("\"");

Use like this.

List<String> stockList = new ArrayList<String>();
stockList.add("stock1");
stockList.add("stock2");

String[] stockArr = new String[stockList.size()];
stockArr = stockList.toArray(stockArr);

for(String s : stockArr)
    System.out.println(s);

rapidjson is a C++ JSON parser/generator designed to be fast and small memory footprint.

There is a performance comparison with YAJL and JsonCPP.

Update:

I created an open source project Native JSON benchmark, which evaluates 29 (and increasing) C/C++ JSON libraries, in terms of conformance and performance. This should be an useful reference.

I think there are a few things to understand when working with API Gateway integration with Lambda.

Lambda Integration vs Lambda Proxy Integration

There used to be only Lambda Integration which requires mapping templates. I suppose this is why still seeing many examples using it.

• How to pass a querystring or route parameter to AWS Lambda from Amazon API Gateway

As of September 2017, you no longer have to configure mappings to access the request body.

• Serverless Architecture on AWS

Lambda Proxy Integration, If you enable it, API Gateway will map every request to JSON and pass it to Lambda as the event object. In the Lambda function you’ll be able to retrieve query string parameters, headers, stage variables, path parameters, request context, and the body from it.

Without enabling Lambda Proxy Integration, you’ll have to create a mapping template in the Integration Request section of API Gateway and decide how to map the HTTP request to JSON yourself. And you’d likely have to create an Integration Response mapping if you were to pass information back to the client.

Before Lambda Proxy Integration was added, users were forced to map requests and responses manually, which was a source of consternation, especially with more complex mappings.

Words need to navigate the thinking. To get the terminologies straight.

• Lambda Proxy Integration = Pass through
  Simply pass the HTTP request through to lambda.

• Lambda Integration = Template transformation
  Go through a transformation process using the Apache Velocity template and you need to write the template by yourself.

body is escaped string, not JSON

Using Lambda Proxy Integration, the body in the event of lambda is a string escaped with backslash, not a JSON.

"body": "{\"foo\":\"bar\"}" 

If tested in a JSON formatter.

Parse error on line 1:
{\"foo\":\"bar\"}
-^
Expecting 'STRING', '}', got 'undefined'

The document below is about response but it should apply to request.

• I received a "malformed Lambda proxy response" error or a 502 status code with Amazon API Gateway. How do I resolve this?

The body field, if you are returning JSON, must be converted to a string or it will cause further problems with the response. You can use JSON.stringify to handle this in Node.js functions; other runtimes will require different solutions, but the concept is the same.

For JavaScript to access it as a JSON object, need to convert it back into JSON object with json.parse in JapaScript, json.dumps in Python.

• How To Work with JSON in JavaScript

Strings are useful for transporting but you’ll want to be able to convert them back to a JSON object on the client and/or the server side.

The AWS documentation shows what to do.

if (event.body !== null && event.body !== undefined) {
    let body = JSON.parse(event.body)
    if (body.time) 
        time = body.time;
}
...
var response = {
    statusCode: responseCode,
    headers: {
        "x-custom-header" : "my custom header value"
    },
    body: JSON.stringify(responseBody)
};
console.log("response: " + JSON.stringify(response))
callback(null, response);

I think that this below is accurate and it may help. Feel free to correct it if you find any errors. I'm new at C.

char str[]  

1. array of values of type char, with its own address in memory
2. array of values of type char, with its own address in memory as many consecutive addresses as elements in the array

3. including termination null character '\0' &str, &str[0] and str, all three represent the same location in memory which is address of the first element of the array str

   char *strPtr = &str[0]; //declaration and initialization

alternatively, you can split this in two:

char *strPtr; strPtr = &str[0];

4. strPtr is a pointer to a char
5. strPtr points at array str
6. strPtr is a variable with its own address in memory
7. strPtr is a variable that stores value of address &str[0]
8. strPtr own address in memory is different from the memory address that it stores (address of array in memory a.k.a &str[0])
9. &strPtr represents the address of strPtr itself

I think that you could declare a pointer to a pointer as:

char **vPtr = &strPtr;  

declares and initializes with address of strPtr pointer

Alternatively you could split in two:

char **vPtr;
*vPtr = &strPtr

10. *vPtr points at strPtr pointer
11. *vPtr is a variable with its own address in memory
12. *vPtr is a variable that stores value of address &strPtr
13. final comment: you can not do str++, str address is a const, but you can do strPtr++

        }, []).filter(function (res, obj) {

        });

        const finalData2 = Array.from(hashData.values());

I recommend second example , it is faster.

Whenever possible, you should avoid parsing the output of ls (see Greg's wiki on the subject). Basically, the output of ls will be ambiguous if there are funny characters in any of the filenames. It's also usually a waste of time. In this case, when you execute ls -d */, what happens is that the shell expands */ to a list of subdirectories (which is already exactly what you want), passes that list as arguments to ls -d, which looks at each one, says "yep, that's a directory all right" and prints it (in an inconsistent and sometimes ambiguous format). The ls command isn't doing anything useful!

Well, ok, it is doing one thing that's useful: if there are no subdirectories, */ will get left as is, ls will look for a subdirectory named "*", not find it, print an error message that it doesn't exist (to stderr), and not print the "*/" (to stdout).

The cleaner way to make an array of subdirectory names is to use the glob (*/) without passing it to ls. But in order to avoid putting "*/" in the array if there are no actual subdirectories, you should set nullglob first (again, see Greg's wiki):

shopt -s nullglob
array=(*/)
shopt -u nullglob # Turn off nullglob to make sure it doesn't interfere with anything later
echo "${array[@]}"  # Note double-quotes to avoid extra parsing of funny characters in filenames

If you want to print an error message if there are no subdirectories, you're better off doing it yourself:

if (( ${#array[@]} == 0 )); then
    echo "No subdirectories found" >&2
fi

$(function () {
    $("#txtSearch").keyup(function (event) {
        var txt = $("#txtSearch").val()

            $("span.hilightable").each(function (i, v) {
                v.innerHTML = v.innerText.replace(txt, "<hilight>" + txt + "</hilight>");
            });

        }
    });
});

Using

mapper.configure(
    JsonReadFeature.ALLOW_UNESCAPED_CONTROL_CHARS.mappedFeature(), 
    true
);

See javadoc:

/**
 * Feature that determines whether parser will allow
 * JSON Strings to contain unescaped control characters
 * (ASCII characters with value less than 32, including
 * tab and line feed characters) or not.
 * If feature is set false, an exception is thrown if such a
 * character is encountered.
 *<p>
 * Since JSON specification requires quoting for all control characters,
 * this is a non-standard feature, and as such disabled by default.

Old option JsonParser.Feature.ALLOW_UNQUOTED_CONTROL_CHARS was deprecated since 2.10.

I do know that the account needs to have "Log on as a Service" privileges. Other than that, I'm not sure. A quick reference to Log on as a Service can be found here, and there is a lot of information of specific privileges here.

The shortest one I could come up with is:

chmod -R a=r,u+w,a+X /foo

which works on GNU/Linux, and I believe on Posix in general (from my reading of: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/chmod.html).

What this does is:

1. Set file/directory to r__r__r__ (0444)
2. Add w for owner, to get rw_r__r__ (0644)
3. Set execute for all if a directory (0755 for dir, 0644 for file).

Importantly, the step 1 permission clears all execute bits, so step 3 only adds back execute bits for directories (never files). In addition, all three steps happen before a directory is recursed into (so this is not equivalent to e.g.

chmod -R a=r /foo
chmod -R u+w /foo
chmod -R a+X /foo

since the a=r removes x from directories, so then chmod can't recurse into them.)

For setting up virtual hosts on Apache http-servers that are not yet connected via DNS, I like to use:

curl -s --connect-to ::host-name: http://project1.loc/post.json

Where host-name ist the IP address or the DNS name of the machine on which the web-server is running. This also works well for https-Sites.

To generate a random number between min and max, use:

int randNum = rand()%(max-min + 1) + min;

(Includes max and min)

I just had the same problem with a cookie which was set to expire on "Browsing session end".

Unfortunately it did not so I played a bit with the settings of the browser.

Turned out that the feature that remembers the opened tabs when the browser is closed was the root of the problem. (The feature is named "On startup" - "Continue where I left off". At least on the current version of Chrome).

This also happens with Opera and Firefox.

I found following program works for me

test1.sh 
a=xxx
test2.sh $a

in test2.sh you use $1 to refer variable a in test1.sh

echo $1

The output would be xxx

After lot of researching and looking into different solutions proposed here at StackOverflow. I finally decided to write my own solution. My purpose is to have no-throw mechanism because I don't want to crash if the API is unable to fetch the folder size. This method is not suitable for mult-threaded scenario.

First of all I want to check for valid directories while traversing down the file system tree.

private static boolean isValidDir(File dir){
    if (dir != null && dir.exists() && dir.isDirectory()){
        return true;
    }else{
        return false;
    }
}

Second I do not want my recursive call to go into symlinks (softlinks) and include the size in total aggregate.

public static boolean isSymlink(File file) throws IOException {
    File canon;
    if (file.getParent() == null) {
        canon = file;
    } else {
        canon = new File(file.getParentFile().getCanonicalFile(),
                file.getName());
    }
    return !canon.getCanonicalFile().equals(canon.getAbsoluteFile());
}

Finally my recursion based implementation to fetch the size of the specified directory. Notice the null check for dir.listFiles(). According to javadoc there is a possibility that this method can return null.

public static long getDirSize(File dir){
    if (!isValidDir(dir))
        return 0L;
    File[] files = dir.listFiles();
    //Guard for null pointer exception on files
    if (files == null){
        return 0L;
    }else{
        long size = 0L;
        for(File file : files){
            if (file.isFile()){
                size += file.length();
            }else{
                try{
                    if (!isSymlink(file)) size += getDirSize(file);
                }catch (IOException ioe){
                    //digest exception
                }
            }
        }
        return size;
    }
}

Some cream on the cake, the API to get the size of the list Files (might be all of files and folder under root).

public static long getDirSize(List<File> files){
    long size = 0L;
    for(File file : files){
        if (file.isDirectory()){
            size += getDirSize(file);
        } else {
            size += file.length();
        }
    }
    return size;
}

Yes, just a syntax problem. Try this instead:

if (reader["usr.ursrdaystime"] != DBNull.Value)

.Equals() is checking to see if two Object instances are the same.

def import_class(cl):
    d = cl.rfind(".")
    classname = cl[d+1:len(cl)]
    m = __import__(cl[0:d], globals(), locals(), [classname])
    return getattr(m, classname)

basically hidden fields will be more useful and advantages to use with multi step form. we can use hidden fields to pass one step information to next step using hidden and keep it forwarding till the end step.

1. CSRF tokens.

Cross-site request forgery is a very common website vulnerability. Requiring a secret, user-specific token in all form submissions will prevent CSRF attacks since attack sites cannot guess what the proper token is and any form submissions they perform on the behalf of the user will always fail.

2. Save state in multi-page forms.

If you need to store what step in a multi-page form the user is currently on, use hidden input fields. The user doesn't need to see this information, so hide it in a hidden input field.

General rule: Use the field to store anything that the user doesn't need to see, but that you want to send to the server on form submission.

How about:

SimpleDateFormat fmt = new SimpleDateFormat("yyyyMMdd");
return fmt.format(date1).equals(fmt.format(date2));

You can also set the timezone to the SimpleDateFormat, if needed.

Also, it is very likely, that problem with proxy settings.

Any who didn't overcome Tomact starting problrem, - try in NetBeans choose No Proxy in the Tools -> Options -> General tab.

It helped me.

You are using the wrong iteration counter, replace inp.charAt(i) with inp.charAt(j).

Any ideas on how to parse "2010-08-17 12:09:36" with new Date()?

Until ES5, there was no string format that browsers were required to support, though there are a number that are widely supported. However browser support is unreliable an inconsistent, e.g. some will allow out of bounds values and others wont, some support certain formats and others don't, etc.

ES5 introduced support for some ISO 8601 formats, however the OP is not compliant with ISO 8601 and not all browsers in use support it anyway.

The only reliable way is to use a small parsing function. The following parses the format in the OP and also validates the values.

/* Parse date string in format yyyy-mm-dd hh:mm:ss_x000D_
** If string contains out of bounds values, an invalid date is returned_x000D_
** _x000D_
** @param {string} s - string to parse, e.g. "2010-08-17 12:09:36"_x000D_
**                     treated as "local" date and time_x000D_
** @returns {Date}   - Date instance created from parsed string_x000D_
*/_x000D_
function parseDateString(s) {_x000D_
  var b = s.split(/\D/);_x000D_
  var d = new Date(b[0], --b[1], b[2], b[3], b[4], b[5]);_x000D_
  return d && d.getMonth() == b[1] && d.getHours() == b[3] &&_x000D_
         d.getMinutes() == b[4]? d : new Date(NaN);_x000D_
}_x000D_
  _x000D_
document.write(_x000D_
  parseDateString('2010-08-17 12:09:36') + '<br>' +  // Valid values_x000D_
  parseDateString('2010-08-45 12:09:36')             // Out of bounds date_x000D_
);

Assuming that you're only using the array for lookup, you can use a Set (introduced in ES6), which allows you to find an element in O(1), meaning that lookup is sublinear. With the traditional methods of .includes() and .indexOf(), you still may need to look at all 500 (ie: N) elements in your array if the item specified doesn't exist in the array (or is the last item). This can be inefficient, however, with the help of a Set, you don't need to look at all elements, and instead, instantly check if the element is within your set:

const blockedTile = new Set(["118", "67", "190", "43", "135", "520"]);

if(blockedTile.has("118")) {
  // 118 is in your Set
  console.log("Found 118");
}

If for some reason you need to convert your set back into an array, you can do so through the use of Array.from() or the spread syntax (...), however, this will iterate through the entire set's contents (which will be O(N)). Sets also don't keep duplicates, meaning that your array won't contain duplicate items.

You can try this one

img{
    max-height:500px;
    max-width:500px;
    height:auto;
    width:auto;
}

This keeps the aspect ratio of the image and prevents either the two dimensions exceed 500px

This is nice ! Thanks for writing this. I needed this exact piece of code for Windows. My goal was to do this by learning to do it with Linux first and then learn the Windows shell which I was not happy about having to do so you saved me some time!

My Linux version is at the bottom of this post. I've been experimenting with which file to insert the prefs into. It seems picky. First I tried in ~/.mozilla/firefox/*.default/prefs.js but it didn't load very well. The about:config screen never showed my changes. Currently I've been trying to edit the actual Firefox defaults file. If someone has the knowledge off the top of their head could they rewrite the Windows code to only add the lines if they're not already in there? I have no idead how to do sed/awk stuff in Windows without installing Cygwin first.

The only change I was able to make to the Windows scripts is above in the quoted part. I change the IP to %1 so when you call the script from the command line you can give it an option instead of having to change the file.

#!/bin/bash
version="`firefox -v | awk '{print substr($3,1,3)}'`"
echo $version " is the version."
# Insert an ip into firefox for the proxy if there isn't one
if
! grep network.proxy.http /etc/firefox-$version/pref/firefox.js 
  then echo 'pref("network.proxy.http", "'"$1"'")";' >> /etc/firefox-$version/pref/firefox.js 
fi

# Even if there is change it to what we want
sed -i s/^.*network.proxy.http\".*$/'pref("network.proxy.http", "'"$1"')";'/  /etc/firefox-$version/pref/firefox.js 

# Set the port
if ! grep network.proxy.http_port /etc/firefox-$version/pref/firefox.js 
  then echo 'pref("network.proxy.http_port", 9980);' >> /etc/firefox-$version/pref/firefox.js 
  else sed -i s/^.*network.proxy.http_port.*$/'pref("network.proxy.http_port", 9980);'/ /etc/firefox-$version/pref/firefox.js 
fi

# Turn on the proxy
if ! grep network.proxy.type  /etc/firefox-$version/pref/firefox.js 
  then echo 'pref("network.proxy.type", 1);' >> /etc/firefox-$version/pref/firefox.js 
  else sed -i s/^.*network.proxy.type.*$/'pref("network.proxy.type", 1)";'/ /etc/firefox-$version/pref/firefox.js

Just use the std:: qualifier in front of string in your header files.

In fact, you should use it for istream and ostream also - and then you will need #include <iostream> at the top of your header file to make it more self contained.

If you have array of custom Objects, you can search by specific property like this:

if let index = doctorsInArea.firstIndex(where: {$0.id == doctor.id}){
    doctorsInArea.remove(at: index)
}

or if you want to search by name for example

if let index = doctorsInArea.firstIndex(where: {$0.name == doctor.name}){
    doctorsInArea.remove(at: index)
}

You can also alternatively use System.CodeDom.Compiler.TempFileCollection.

string tempDirectory = @"c:\\temp";
TempFileCollection coll = new TempFileCollection(tempDirectory, true);
string filename = coll.AddExtension("txt", true);
File.WriteAllText(Path.Combine(tempDirectory,filename),"Hello World");

Here I used a txt extension but you can specify whatever you want. I also set the keep flag to true so that the temp file is kept around after use. Unfortunately, TempFileCollection creates one random file per extension. If you need more temp files, you can create multiple instances of TempFileCollection.

The /usr/bin/env python becomes very useful when your scripts depend on environment settings for example using scripts which rely on python virtualenv. Each virtualenv has its own version of python binary which is required for adding packages installed in virtualenv to python path (without touching PYTHONPATH env).

As more and more people have started to used virtualenv for python development prefer to use /usr/bin/env python unless you don't want people to use their custom python binary.

Note: You should also understand that there are potential security issues (in multiuser environments) when you let people run your scripts in their custom environments. You can get some ideas from here.

I solved it by rewriting package.json with the exact values warnings were about.

Warnings when running npm:

npm WARN [email protected] requires a peer of es6-shim@^0.33.3 but none was installed.
npm WARN [email protected] requires a peer of [email protected]

In package.json, write

"es6-shim": "^0.33.3",
"reflect-metadata": "0.1.2",

Then, delete node_modules directory.

Finally, run the command below:

npm install

if you search in Column (A) use :

=INDIRECT("A" & SUMPRODUCT(MAX((A:A<>"")*(ROW(A:A)))))

if your range is A1:A10 you can use:

=INDIRECT("A" & SUMPRODUCT(MAX(($A$1:$A10<>"")*(ROW($A$1:$A10)))))

in this formula :

SUMPRODUCT(MAX(($A$1:$A10<>"")*(ROW($A$1:$A10))))

returns last non blank row number ,and indirect() returns cell value.

Try this solution, in my softwarew work very well:

if (obj != null)
{
    if (obj is DateTime)
    {
        if (DateTime.MinValue == ((DateTime)obj))
        {

            xlWorkSheet.Cells[x,y] = String.Empty;

        }
        else
        {

            dynamic opp = ((DateTime)obj);
            xlWorkSheet.Cells[x,y] = (DateTime)opp;

        }
    }
}

When comparing only the date of the datatimes, use the Date property. So this should work fine for you

datetime1.Date == datetime2.Date

in a simple sentence, I cay say: The essence of abstraction is to extract essential properties while omitting inessential details. But why should we omit inessential details? The key motivator is preventing the risk of change. You might consider abstraction is same as encapsulation. But encapsulation means the act of enclosing one or more items within a container, not hiding details. If you make the argument that "everything that was encapsulated was also hidden." This is obviously not true. For example, even though information may be encapsulated within record structures and arrays, this information is usually not hidden (unless hidden via some other mechanism).

You need other headers, not only access-control-allow-origin. If your request have the "Access-Control-Allow-Origin" header, you must copy it into the response headers, If doesn't, you must check the "Origin" header and copy it into the response. If your request doesn't have Access-Control-Allow-Origin not Origin headers, you must return "*".

You can read the complete explanation here: http://www.html5rocks.com/en/tutorials/cors/#toc-adding-cors-support-to-the-server

and this is the function I'm using to write cross domain headers:

func writeCrossDomainHeaders(w http.ResponseWriter, req *http.Request) {
    // Cross domain headers
    if acrh, ok := req.Header["Access-Control-Request-Headers"]; ok {
        w.Header().Set("Access-Control-Allow-Headers", acrh[0])
    }
    w.Header().Set("Access-Control-Allow-Credentials", "True")
    if acao, ok := req.Header["Access-Control-Allow-Origin"]; ok {
        w.Header().Set("Access-Control-Allow-Origin", acao[0])
    } else {
        if _, oko := req.Header["Origin"]; oko {
            w.Header().Set("Access-Control-Allow-Origin", req.Header["Origin"][0])
        } else {
            w.Header().Set("Access-Control-Allow-Origin", "*")
        }
    }
    w.Header().Set("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE")
    w.Header().Set("Connection", "Close")

}

If you are using an external style sheet, the code could look something like this:

@font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
.junebug { font-family: Junebug; font-size: 4.2em; }

And should be saved in a separate .css file (eg styles.css). If your .css file is in a location separate from the page code, the actual font file should have the same path as the .css file, NOT the .html or .php web page file. Then the web page needs something like:

<link rel="stylesheet" href="css/styles.css">

in the <head> section of your html page. In this example, the font file should be located in the css folder along with the stylesheet. After this, simply add the class="junebug" inside any tag in your html to use Junebug font in that element.

If you're putting the css in the actual web page, add the style tag in the head of the html like:

<style>
    @font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
</style>

And the actual element style can either be included in the above <style> and called per element by class or id, or you can just declare the style inline with the element. By element I mean <div>, <p>, <h1> or any other element within the html that needs to use the Junebug font. With both of these options, the font file (Junebug.ttf) should be located in the same path as the html page. Of these two options, the best practice would look like:

<style>
    @font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
    .junebug { font-family: Junebug; font-size: 4.2em; }
</style>

and

<h1 class="junebug">This is Junebug</h1>

And the least acceptable way would be:

<style>
    @font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
</style>

and

<h1 style="font-family: Junebug;">This is Junebug</h1>

The reason it's not good to use inline styles is best practice dictates that styles should be kept all in one place so editing is practical. This is also the main reason that I recommend using the very first option of using external style sheets. I hope this helps.

If you want to SELECT based on the value of another SELECT, then you probably want a "subselect":

http://beginner-sql-tutorial.com/sql-subquery.htm

For example, (from the link above):

1. You want the first and last names from table "student_details" ...

2. But you only want this information for those students in "science" class:

    SELECT id, first_name
    FROM student_details
    WHERE first_name IN (SELECT first_name
    FROM student_details
    WHERE subject= 'Science'); 
   

Frankly, I'm not sure this is what you're looking for or not ... but I hope it helps ... at least a little...

IMHO...

I have written an article that helps with this (https://msdn.microsoft.com/magazine/mt736453). You can use the SolSoft.DataBinding NuGet package. Then you can write code like this:

public class TestViewModel : IRaisePropertyChanged
{
  public TestViewModel()
  {
    this.m_nameProperty = new NotifyProperty<string>(this, nameof(Name), null);
  }

  private readonly NotifyProperty<string> m_nameProperty;
  public string Name
  {
    get
    {
      return m_nameProperty.Value;
    }
    set
    {
      m_nameProperty.SetValue(value);
    }
  }

  // Plus implement IRaisePropertyChanged (or extend BaseViewModel)
}

Benefits:

1. base class is optional
2. no reflection on every 'set value'
3. can have properties that depend on other properties, and they all automatically raise the appropriate events (article has an example of this)

You can also use EXIT_SUCCESS instead of return 0;. The macro EXIT_SUCCESS is actually defined as zero, but makes your program more readable.

I would really opt for FlowPaper, especially their new Elements mode that can be found here : https://flowpaper.com/demo/

It flattens the PDFs significantly at the same time as keeping text sharp which means that it will load much faster on mobile devices

Here you can try something like this

EDIT: REVISED EXAMPLE (added one new solution) http://jsfiddle.net/jszjz/10/

Code explanation

var jqThis = $('#adjinput'), //object of the input field in jQuery
    fontSize = parseInt( jqThis.css('font-size') ) / 2, //its font-size
    //its min Width (the box won't become smaller than this
    minWidth= parseInt( jqThis.css('min-width') ), 
    //its maxWidth (the box won't become bigger than this)
    maxWidth= parseInt( jqThis.css('max-width') );

jqThis.bind('keydown', function(e){ //on key down
   var newVal = (this.value.length * fontSize); //compute the new width

   if( newVal  > minWidth && newVal <= maxWidth ) //check to see if it is within Min and Max
       this.style.width = newVal + 'px'; //update the value.
});

and the css is pretty straightforward too

#adjinput{
    max-width:200px !important;
    width:40px;
    min-width:40px;
    font-size:11px;
}

EDIT: Another solution is to havethe user type what he wants and on blur (focus out), grab the string (in the same font size) place it in a div - count the div's width - and then with a nice animate with a cool easing effect update the input fields width. The only drawback is that the input field will remain "small" while the user types. Or you can add a timeout : ) you can check such a kind of solution on the fiddle above too!

Ubuntu 20.04:

Option 1 - set up a gem installation directory for your user account

For bash (for zsh, we would use .zshrc of course)

echo '# Install Ruby Gems to ~/gems' >> ~/.bashrc
echo 'export GEM_HOME="$HOME/gems"' >> ~/.bashrc
echo 'export PATH="$HOME/gems/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

Option 2 - use snap

Uninstall the apt-version (ruby-full) and reinstall it with snap

sudo apt-get remove ruby
sudo snap install ruby --classic

I always include the js files in the head of the html document and them in the action just call the javascript function. Something like this:

action="javascript:checkout()"

You try this?

Don't forget include the script reference in the html head.

I don't know cause of that works in firefox. Regards.

text doesn't work with len function.

ntext, text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead. For more information, see Using Large-Value Data Types.

Here is the Java Implementation of this approach:

public static int countAllFactors(int num)
{
    TreeSet<Integer> tree_set = new TreeSet<Integer>();
    for (int i = 1; i * i <= num; i+=1)
    {
        if (num % i == 0)
        {
            tree_set.add(i);
            tree_set.add(num / i);
        }
    }
    System.out.print(tree_set);
    return tree_set.size();
}

Try this:

$mpdf->Output('my_filename.pdf','D'); 

because:

D - means Download
F - means File-save only

As @danh suggested, my issue was that I was presenting the modal vc before the UITabBarController was ready. However, I felt uncomfortable relying on a fixed delay before presenting the view controller (from my testing, I needed to use a 0.05-0.1s delay in performSelector:withDelay:). My solution is to add a block that gets called on UITabBarController's viewDidAppear: method:

PRTabBarController.h:

@interface PRTabBarController : UITabBarController

@property (nonatomic, copy) void (^viewDidAppearBlock)(BOOL animated);

@end

PRTabBarController.m:

#import "PRTabBarController.h"

@implementation PRTabBarController

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    if (self.viewDidAppearBlock) {
        self.viewDidAppearBlock(animated);
    }
}

@end

Now in application:didFinishLaunchingWithOptions:

PRTabBarController *tabBarController = [[PRTabBarController alloc] init];

// UIWindow initialization, etc.

__weak typeof(tabBarController) weakTabBarController = tabBarController;
tabBarController.viewDidAppearBlock = ^(BOOL animated) {
    MyViewController *viewController = [MyViewController new];
    viewController.modalPresentationStyle = UIModalPresentationOverFullScreen;
    UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
    [weakTabBarController.tabBarController presentViewController:navigationController animated:NO completion:nil];
    weakTabBarController.viewDidAppearBlock = nil;
};

Technically possible. You would probably reference employees_ce in deductions and employees_sn. But why don't you merge employees_sn and employees_ce? I see no reason why you have two table. No one to many relationship. And (not in this example) many columns.

If you do two references for one column, an employee must have an entry in both tables.

(ps - I couldn't comment) I think your best bet is something like you've done, or similar to:

$user = User::where('mobile', Input::get('mobile'));
$user->exists() and $user = $user->first();

Oh, also: count() instead if exists but this could be something used after get.

Annotation based approach is better. But sometimes manual operation is needed. For this purpose you can use without method of ObjectWriter.

ObjectMapper mapper   = new ObjectMapper().configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)
ObjectWriter writer   = mapper.writer().withoutAttribute("property1").withoutAttribute("property2");
String       jsonText = writer.writeValueAsString(sourceObject);

This is what you need to add to make it work.

response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Credentials", "true");
response.setHeader("Access-Control-Allow-Methods", "GET,HEAD,OPTIONS,POST,PUT");
response.setHeader("Access-Control-Allow-Headers", "Access-Control-Allow-Headers, Origin,Accept, X-Requested-With, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers");

The browser sends a preflight request (with method type OPTIONS) to check if the service hosted on the server is allowed to be accessed from the browser on a different domain. In response to the preflight request if you inject above headers the browser understands that it is ok to make further calls and i will get a valid response to my actual GET/POST call. you can constraint the domain to which access is granted by using Access-Control-Allow-Origin", "localhost, xvz.com" instead of * . ( * will grant access to all domains)

The best way is to simply use Convert.ToInt32. It is fast and also rounds correctly.

Why make it more complicated?

Works on All android Versions:

String[] TO = {"[email protected]"};
    Uri uri = Uri.parse("mailto:[email protected]")
            .buildUpon()
            .appendQueryParameter("subject", "subject")
            .appendQueryParameter("body", "body")
            .build();
    Intent emailIntent = new Intent(Intent.ACTION_SENDTO, uri);
    emailIntent.putExtra(Intent.EXTRA_EMAIL, TO);
    startActivity(Intent.createChooser(emailIntent, "Send mail..."));

updated for android 10, now using kotlin.

fun Context.sendEmail(adress:String?,subject:String?,body:String?){
val TO = arrayOf(adress)
val uri = Uri.parse(adress)
    .buildUpon()
    .appendQueryParameter("subject", subject)
    .appendQueryParameter("body", body)
    .build()
val emailIntent = Intent(Intent.ACTION_SENDTO, uri)
emailIntent.setData(Uri.parse("mailto:$adress"));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
emailIntent.putExtra(Intent.EXTRA_TEXT, body);
emailIntent.putExtra(Intent.EXTRA_EMAIL, TO)
ContextCompat.startActivity(this,Intent.createChooser(emailIntent, "Send 
mail..."),null)
}

As a Python lover and Android programmer, I'm sad to say this is not a good way to go. There are two problems:

One problem is that there is a lot more than just a programming language to the Android development tools. A lot of the Android graphics involve XML files to configure the display, similar to HTML. The built-in java objects are integrated with this XML layout, and it's a lot easier than writing your code to go from logic to bitmap.

The other problem is that the G1 (and probably other Android devices for the near future) are not that fast. 200 MHz processors and RAM is very limited. Even in Java, you have to do a decent amount of rewriting-to-avoid-more-object-creation if you want to make your app perfectly smooth. Python is going to be too slow for a while still on mobile devices.

One pretty easy way to work around this issue is to append a trailing slash ...

e.g.:

use :

/somepath/filename.jpg/

instead of:

/somepath/filename.jpg

One other option that hasn't been mentioned yet: use Groovy. Groovy allows you to access private instance variables as a side effect of the design of the language. Whether or not you have a getter for the field, you can just use

def obj = new IWasDesignedPoorly()
def hashTable = obj.getStuffIWant()

My site is hosted on MochaHost, i had a tough time to setup the .htaccess file so that i can remove the index.php from my urls. However, after some googling, i combined the answer on this thread and other answers. My final working .htaccess file has the following contents:

<IfModule mod_rewrite.c>
    # Turn on URL rewriting
    RewriteEngine On

    # If your website begins from a folder e.g localhost/my_project then 
    # you have to change it to: RewriteBase /my_project/
    # If your site begins from the root e.g. example.local/ then
    # let it as it is
    RewriteBase /

    # Protect application and system files from being viewed when the index.php is missing
    RewriteCond $1 ^(application|system|private|logs)

    # Rewrite to index.php/access_denied/URL
    RewriteRule ^(.*)$ index.php/access_denied/$1 [PT,L]

    # Allow these directories and files to be displayed directly:
    RewriteCond $1 ^(index\.php|robots\.txt|favicon\.ico|public|app_upload|assets|css|js|images)

    # No rewriting
    RewriteRule ^(.*)$ - [PT,L]

    # Rewrite to index.php/URL
    RewriteRule ^(.*)$ index.php?/$1 [PT,L]
</IfModule>

For SQL Server you can use the dense_rank and additional windowing functions to get all rows AND columns with duplicated values on specified columns. Here is an example...

with t as (
    select col1 = 'a', col2 = 'b', col3 = 'c', other = 'r1' union all
    select col1 = 'c', col2 = 'b', col3 = 'a', other = 'r2' union all
    select col1 = 'a', col2 = 'b', col3 = 'c', other = 'r3' union all
    select col1 = 'a', col2 = 'b', col3 = 'c', other = 'r4' union all
    select col1 = 'c', col2 = 'b', col3 = 'a', other = 'r5' union all
    select col1 = 'a', col2 = 'a', col3 = 'a', other = 'r6'
), tdr as (
    select 
        *, 
        total_dr_rows = count(*) over(partition by dr)
    from (
        select 
            *, 
            dr = dense_rank() over(order by col1, col2, col3),
            dr_rn = row_number() over(partition by col1, col2, col3 order by other)
        from 
            t
    ) x
)

select * from tdr where total_dr_rows > 1

This is taking a row count for each distinct combination of col1, col2, and col3.

Another good way to serialize json into c# is below:

RootObject ro = new RootObject();
     try
    {

        StreamReader sr = new StreamReader(FileLoc);
        string jsonString = sr.ReadToEnd();
        JavaScriptSerializer ser = new JavaScriptSerializer();
        ro = ser.Deserialize<RootObject>(jsonString);


   }

you need to add a reference to system.web.extensions in .net 4.0 this is in program files (x86) > reference assemblies> framework> system.web.extensions.dll and you need to be sure you're using just regular 4.0 framework not 4.0 client

You seem to be looking for pass-by-reference, to do that make your function look this way (note the ampersand):

function foo(&$array)
{
    $array[3]=$array[0]+$array[1]+$array[2];
}

Alternately, you can assign the return value of the function to a variable:

function foo($array)
{
    $array[3]=$array[0]+$array[1]+$array[2];
    return $array;
}

$waffles = foo($waffles)

You can use this code

ArrayList<TypeA> a = new ArrayList<TypeA>();
Object[] o = a.toArray();

Then if you want that to get that object back into TypeA just check it with instanceOf method.

You are doing most things correctly, it looks like the only problem you are hitting is that you are not triggering the change method after you are setting the new value. Without a change event, Select2 cannot know that the underlying value has changed so it will only display the placeholder. Changing your last part to

.val(initial_creditor_id).trigger('change');

Should fix your issue, and you should see the UI update right away.

This is assuming that you have an <option> already that has a value of initial_creditor_id. If you do not Select2, and the browser, will not actually be able to change the value, as there is no option to switch to, and Select2 will not detect the new value. I noticed that your <select> only contains a single option, the one for the placeholder, which means that you will need to create the new <option> manually.

var $option = $("<option selected></option>").val(initial_creditor_id).text("Whatever Select2 should display");

And then append it to the <select> that you initialized Select2 on. You may need to get the text from an external source, which is where initSelection used to come into play, which is still possible with Select2 4.0.0. Like a standard select, this means you are going to have to make the AJAX request to retrieve the value and then set the <option> text on the fly to adjust.

var $select = $('.creditor_select2');

$select.select2(/* ... */); // initialize Select2 and any events

var $option = $('<option selected>Loading...</option>').val(initial_creditor_id);

$select.append($option).trigger('change'); // append the option and update Select2

$.ajax({ // make the request for the selected data object
  type: 'GET',
  url: '/api/for/single/creditor/' + initial_creditor_id,
  dataType: 'json'
}).then(function (data) {
  // Here we should have the data object
  $option.text(data.text).val(data.id); // update the text that is displayed (and maybe even the value)
  $option.removeData(); // remove any caching data that might be associated
  $select.trigger('change'); // notify JavaScript components of possible changes
});

While this may look like a lot of code, this is exactly how you would do it for non-Select2 select boxes to ensure that all changes were made.

this is the most general solution

$('body').on('shown.bs.modal', '.modal', function () {
    $(this).find(":input:not(:button):visible:enabled:not([readonly]):first").focus();
});

• works with modals added to DOM after page load
• works with input, textarea, select and not with button
• ommits hidden, disabled, readonly
• works with faded modals, no need for setInterval

If you want to send background email, then please do the below

 public void SendEmail(string address, string subject, string message)
 {
 Thread threadSendMails;
 threadSendMails = new Thread(delegate()
    {

      //Place your Code here 

     });
  threadSendMails.IsBackground = true;
  threadSendMails.Start();
}

and add namespace

using System.Threading;

In my case (using windows 10) gradlew.bat has the following lines of code in:

set DIRNAME=%~dp0
if "%DIRNAME%" == "" set DIRNAME=.
set APP_BASE_NAME=%~n0
set APP_HOME=%DIRNAME%

The APP_HOME variable is essentially gradles root folder for the project, so, if this gets messed up in some way you are going to get:

Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain

For me, this had been messed up because my project folder structure had an ampersand (&) in it. Eg C:\Test&Dev\MyProject

So, gradel was trying to find the gradle-wrapper.jar file in a root folder of C:\Test (stripping off everything after and including the '&')

I found this by adding the following line below the set APP_HOME=%DIRNAME% line above. Then ran the bat file to see the result.

echo "%APP_HOME%"

There will be a few other 'special characters' that could break a path/directory.

If there is an object with 8 methods and you have a test where you want to call 7 real methods and stub one method you have two options:

1. Using a mock you would have to set it up by invoking 7 callRealMethod and stub one method
2. Using a spy you have to set it up by stubbing one method

The official documentation on doCallRealMethod recommends using a spy for partial mocks.

See also javadoc spy(Object) to find out more about partial mocks. Mockito.spy() is a recommended way of creating partial mocks. The reason is it guarantees real methods are called against correctly constructed object because you're responsible for constructing the object passed to spy() method.

I was able to get what I needed using Martinho Fernandes' solution below. The code is:

var test = "My cow always gives milk";

var testRE = test.match("cow(.*)milk");
alert(testRE[1]);

You'll notice that I am alerting the testRE variable as an array. This is because testRE is returning as an array, for some reason. The output from:

My cow always gives milk

Changes into:

always gives

You can also simply add the font tag inside the p tag.

CSS sheet:

<style type="text/css">
   p { font:15px Arial; color:white; }
</style>

and in HTML page:

<p> Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
tempor incididunt ut labore et dolore magna aliqua. 
    <font color="red"> 
          Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris     nisi ut aliquip ex ea commodo consequat. 
    </font>
Duis aute irure dolor in reprehenderit in voluptate velit esse
cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non
proident, sunt in culpa qui officia deserunt mollit anim id est laborum. </p>

It works for me. But, in case you need modification, see w3schools for more usage :)

If the text contains \r\n that need to be converted into new lines use the 'Extended' or 'Regular expression' modes and escape the backslash character in 'Find what':

Find what: \\r\\n

Replace with: \r\n

I just found a solution to the problem here:

http://willcodeforcoffee.com/2007/01/31/cakephp-error-500-too-many-redirects/

The .htaccess file in webroot should look like:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>

instead of this:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /projectname
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>

As of Android studio 3.4, You need to put this line in your Layout which holds the RecyclerView.

app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior"

you can use default ng-submitted is set if the form was submitted.

https://docs.angularjs.org/api/ng/directive/form

If you move your datadir, you not only need to give the new datadir permissions, but you need to ensure all parent directories have permission.

I moved my datadir to a hard drive, mounted in Ubuntu as:

/media/*user*/Data/

and my datadir was Databases.

I had to set permissions to 771 to each of the media, user and Data directories:

sudo chmod 771 *DIR*

If this does not work, another way you can get mysql to work is to change user in /etc/mysql/my.cnf to root; though there are no doubt some issues with doing that from a security perspective.

The snippet you're showing doesn't seem to be directly responsible for the error.

This is how you can CAUSE the error:

namespace MyNameSpace
{
   int i; <-- THIS NEEDS TO BE INSIDE THE CLASS

   class MyClass
   {
      ...
   }
}

If you don't immediately see what is "outside" the class, this may be due to misplaced or extra closing bracket(s) }.

Facebook has a strict policy on sharing only the content which a profile makes public to the end user.. Still what you want is possible if the user has actually left the email id open to public domain.. A wild try u can do is send batch requests for the maximum possible batch size to ids..."http://graph.facebook.com/ .. and parse the result to check if email exists and if it does then it matches to the one you want.. you don't need any access_token for the public information ..

in case you want email id of a FB user only possible way is that they authorize ur app and then you can use the access_token thus generated for the required task.

A year has 52 weeks and 1 day or 2 in case of a lap year (52 x 7 = 364). 2012-12-31 would be week 53, a week that would only have 2 days because 2012 is a lap year.

You should be able to match it with: /<primaryAddress>(.+?)<\/primaryAddress>/

The content between the tags will be in the matched group.

You can also use datetime:

>>> import datetime
>>> datetime.datetime.fromtimestamp(1347517370).strftime('%c')
  '2012-09-13 02:22:50'

If you are using a third party library called apache commons-lang, the following solution can be useful:

Use StringUtils class of apache commons-lang :

int i = 5;
StringUtils.leftPad(String.valueOf(i), 3, "0"); // --> "005"

As StringUtils.leftPad() is faster than String.format()

stringWithFileSystemRepresentation doesn't appear to be available in iOS.

Your code should look like:

<?php
if ( that_happened ) {
    header("HTTP/1.0 500 Internal Server Error");
    die();
}

if ( something_else_happened ) {
    header("HTTP/1.0 500 Internal Server Error");
    die();
}

// Your function should return FALSE if something goes wrong
if ( !update_database() ) {
    header("HTTP/1.0 500 Internal Server Error");
    die();
}

// the script can also fail on the above line
// e.g. a mysql error occurred


header('HTTP/1.1 200 OK');
?>

I assume you stop execution if something goes wrong.

I don't blame you for getting frustrated about this. The best way to look at is this. There are potentially three versions of every remote branch:

1. The actual branch on the remote repository
   (e.g., remote repo at https://example.com/repo.git, refs/heads/master)
2. Your snapshot of that branch locally (stored under refs/remotes/...)
   (e.g., local repo, refs/remotes/origin/master)
3. And a local branch that might be tracking the remote branch
   (e.g., local repo, refs/heads/master)

Let's start with git prune. This removes objects that are no longer being referenced, it does not remove references. In your case, you have a local branch. That means there's a ref named random_branch_I_want_deleted that refers to some objects that represent the history of that branch. So, by definition, git prune will not remove random_branch_I_want_deleted. Really, git prune is a way to delete data that has accumulated in Git but is not being referenced by anything. In general, it doesn't affect your view of any branches.

git remote prune origin and git fetch --prune both operate on references under refs/remotes/... (I'll refer to these as remote references). It doesn't affect local branches. The git remote version is useful if you only want to remove remote references under a particular remote. Otherwise, the two do exactly the same thing. So, in short, git remote prune and git fetch --prune operate on number 2 above. For example, if you deleted a branch using the git web GUI and don't want it to show up in your local branch list anymore (git branch -r), then this is the command you should use.

To remove a local branch, you should use git branch -d (or -D if it's not merged anywhere). FWIW, there is no git command to automatically remove the local tracking branches if a remote branch disappears.

The answer about "short-circuiting" is potentially misleading, but has some truth (see below). In the R/S language, && and || only evaluate the first element in the first argument. All other elements in a vector or list are ignored regardless of the first ones value. Those operators are designed to work with the if (cond) {} else{} construction and to direct program control rather than construct new vectors.. The & and the | operators are designed to work on vectors, so they will be applied "in parallel", so to speak, along the length of the longest argument. Both vectors need to be evaluated before the comparisons are made. If the vectors are not the same length, then recycling of the shorter argument is performed.

When the arguments to && or || are evaluated, there is "short-circuiting" in that if any of the values in succession from left to right are determinative, then evaluations cease and the final value is returned.

> if( print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(FALSE && print(1) ) {print(2)} else {print(3)} # `print(1)` not evaluated
[1] 3
> if(TRUE && print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(TRUE && !print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 3
> if(FALSE && !print(1) ) {print(2)} else {print(3)}
[1] 3

The advantage of short-circuiting will only appear when the arguments take a long time to evaluate. That will typically occur when the arguments are functions that either process larger objects or have mathematical operations that are more complex.

That error occurs when you want to add a foreign key with values that don't exist in the primary key of the parent table. You must be sure that the new foreign key UserID in table2 has values that exist in the table1 primary key, sometimes by default it is null or equal to 0.

You could first update all the fields of the foreign key in table2 with a value that exists in the primary key of table1.

update table2 set UserID = 1 where UserID is null

If you want to add different UserIDs you must modify each row with the values you want.

.each() should work for you. http://api.jquery.com/jQuery.each/ or http://api.jquery.com/each/ or you could use .map.

var newArray = $(array).map(function(i) {
    return $('#event' + i, response).html();
});

Edit: I removed the adding of the prepended 0 since it is suggested to not use that.

If you must have it use

var newArray = $(array).map(function(i) {
    var number = '' + i;
    if (number.length == 1) {
        number = '0' + number;
    }   
    return $('#event' + number, response).html();
});

Can you use simply the SVG <title> element and the default browser rendering it conveys? (Note: this is not the same as the title attribute you can use on div/img/spans in html, it needs to be a child element named title)

rect {_x000D_
  width: 100%;_x000D_
  height: 100%;_x000D_
  fill: #69c;_x000D_
  stroke: #069;_x000D_
  stroke-width: 5px;_x000D_
  opacity: 0.5_x000D_
}

<p>Mouseover the rect to see the tooltip on supporting browsers.</p>_x000D_
_x000D_
<svg xmlns="http://www.w3.org/2000/svg">_x000D_
  <rect>_x000D_
    <title>Hello, World!</title>_x000D_
  </rect>_x000D_
</svg>

Alternatively, if you really want to show HTML in your SVG, you can embed HTML directly:

rect {_x000D_
  width: 100%;_x000D_
  height: 100%;_x000D_
  fill: #69c;_x000D_
  stroke: #069;_x000D_
  stroke-width: 5px;_x000D_
  opacity: 0.5_x000D_
}_x000D_
_x000D_
foreignObject {_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
svg div {_x000D_
  text-align: center;_x000D_
  line-height: 150px;_x000D_
}

<svg xmlns="http://www.w3.org/2000/svg">_x000D_
  <rect/>_x000D_
  <foreignObject>_x000D_
    <body xmlns="http://www.w3.org/1999/xhtml">_x000D_
      <div>_x000D_
        Hello, <b>World</b>!_x000D_
      </div>_x000D_
    </body>      _x000D_
  </foreignObject>_x000D_
</svg>

…but then you'd need JS to turn the display on and off. As shown above, one way to make the label appear at the right spot is to wrap the rect and HTML in the same <g> that positions them both together.

To use JS to find where an SVG element is on screen, you can use getBoundingClientRect(), e.g. http://phrogz.net/svg/html_location_in_svg_in_html.xhtml

You probably have to add a class/id to and then make another CSS declaration that hides it as well.

Here are two methods to get more than 1 column in a scalar subquery (or inline subquery) and querying the lookup table only once. This is a bit convoluted but can be the very efficient in some special cases.

1. You can use concatenation to get several columns at once:

   SELECT x, 
          regexp_substr(yz, '[^^]+', 1, 1) y,
          regexp_substr(yz, '[^^]+', 1, 2) z
     FROM (SELECT a.x,
                  (SELECT b.y || '^' || b.z yz
                     FROM b
                    WHERE b.v = a.v)
                     yz
             FROM a)
   

   You would need to make sure that no column in the list contain the separator character.

2. You could also use SQL objects:

   CREATE OR REPLACE TYPE b_obj AS OBJECT (y number, z number);
   
   SELECT x, 
          v.yz.y y,
          v.yz.z z
     FROM (SELECT a.x,
                  (SELECT b_obj(y, z) yz
                     FROM b
                    WHERE b.v = a.v)
                     yz
             FROM a) v
   

Use INSERT ... ON DUPLICATE KEY UPDATE

QUERY:

INSERT INTO table (id, name, age) VALUES(1, "A", 19) ON DUPLICATE KEY UPDATE    
name="A", age=19

If you are using SQL Server try Linked Server

To update and answer the question without breaking mail servers. Later versions of CentOS 7 have MariaDB included as the base along with PostFix which relies on MariaDB. Removing using yum will also remove postfix and perl-DBD-MySQL. To get around this and keep postfix in place, first make a copy of /usr/lib64/libmysqlclient.so.18 (which is what postfix depends on) and then use:

rpm -qa | grep mariadb

then remove the mariadb packages using (changing to your versions):

rpm -e --nodeps "mariadb-libs-5.5.56-2.el7.x86_64"
rpm -e --nodeps "mariadb-server-5.5.56-2.el7.x86_64"
rpm -e --nodeps "mariadb-5.5.56-2.el7.x86_64"

Delete left over files and folders (which also removes any databases):

rm -f /var/log/mariadb
rm -f /var/log/mariadb/mariadb.log.rpmsave
rm -rf /var/lib/mysql
rm -rf /usr/lib64/mysql
rm -rf /usr/share/mysql

Put back the copy of /usr/lib64/libmysqlclient.so.18 you made at the start and you can restart postfix.

There is more detail at https://code.trev.id.au/centos-7-remove-mariadb-replace-mysql/ which describes how to replace mariaDB with MySQL

Readonly textbox in Asp.net

In mathematics, there are sets and ordered sets (osets).

• set: an unordered container of unique elements (Implemented)
• oset: an ordered container of unique elements (NotImplemented)

In Python, only sets are directly implemented. We can emulate osets with regular dict keys (3.7+).

Given

a = [1, 2, 20, 6, 210, 2, 1]
b = {2, 6}

Code

oset = dict.fromkeys(a).keys()
# dict_keys([1, 2, 20, 6, 210])

Demo

Replicates are removed, insertion-order is preserved.

list(oset)
# [1, 2, 20, 6, 210]

Set-like operations on dict keys.

oset - b
# {1, 20, 210}

oset | b
# {1, 2, 5, 6, 20, 210}

oset & b
# {2, 6}

oset ^ b
# {1, 5, 20, 210}

Details

Note: an unordered structure does not preclude ordered elements. Rather, maintained order is not guaranteed. Example:

assert {1, 2, 3} == {2, 3, 1}                    # sets (order is ignored)

assert [1, 2, 3] != [2, 3, 1]                    # lists (order is guaranteed)

One may be pleased to discover that a list and multiset (mset) are two more fascinating, mathematical data structures:

• list: an ordered container of elements that permits replicates (Implemented)
• mset: an unordered container of elements that permits replicates (NotImplemented)*

Summary

Container | Ordered | Unique | Implemented
----------|---------|--------|------------
set       |    n    |    y   |     y
oset      |    y    |    y   |     n
list      |    y    |    n   |     y
mset      |    n    |    n   |     n*  

^{*A multiset can be indirectly emulated with collections.Counter(), a dict-like mapping of multiplicities (counts).}

PL/SQL: numeric or value error: character string buffer too small

is due to the fact that you declare a string to be of a fixed length (say 20), and at some point in your code you assign it a value whose length exceeds what you declared.

for example:

myString VARCHAR2(20);
myString :='abcdefghijklmnopqrstuvwxyz'; --length 26

will fire such an error

Making the Frameworks in the Build Phases optional worked for me.

In Xcode -> Target -> Build Phases -> Link Binary with Libraries -> Make sure the newly added frameworks if any are marked as Optional

Perhaps i missed a step or did something wrong but the methods which are above, didn't bundle data files with PyInstaller into one exe file. Let me share the steps what i have done.

1. step:Write one of the above methods into your py file with importing sys and os modules. I tried both of them. The last one is:

   def resource_path(relative_path):
   """ Get absolute path to resource, works for dev and for PyInstaller """
       base_path = getattr(sys, '_MEIPASS', os.path.dirname(os.path.abspath(__file__)))
       return os.path.join(base_path, relative_path)
   

2. step: Write, pyi-makespec file.py, to the console, to create a file.spec file.

3. step: Open, file.spec with Notepad++ to add the data files like below:

   a = Analysis(['C:\\Users\\TCK\\Desktop\\Projeler\\Converter-GUI.py'],

4. step: I followed the above steps, then saved the spec file. At last opened the console and write, pyinstaller file.spec (in my case, file=Converter-GUI).

Conclusion: There's still more than one file in the dist folder.

Note: I'm using Python 3.5.

EDIT: Finally it works with Jonathan Reinhart's method.

1. step: Add the below codes to your python file with importing sys and os.

   def resource_path(relative_path):
   """ Get absolute path to resource, works for dev and for PyInstaller """
       base_path = getattr(sys, '_MEIPASS', os.path.dirname(os.path.abspath(__file__)))
       return os.path.join(base_path, relative_path)
   

2. step: Call the above function with adding the path of your file:

   image_path = resource_path("Converter-GUI.ico")
   

3. step: Write the above variable that call the function to where your codes need the path. In my case it's:

       self.window.iconbitmap(image_path)
   

4. step: Open the console in the same directory of your python file, write the codes like below:

       pyinstaller --onefile your_file.py
   

5. step: Open the .spec file of the python file and append the a.datas array and add the icon to the exe class, which was given above before the edit in 3'rd step.

6. step: Save and exit the path file. Go to your folder which include the spec and py file. Open again the console window and type the below command:

       pyinstaller your_file.spec
   

After the 6. step your one file is ready to use.

A pointer pointing to a memory location that has been deleted (or freed) is called dangling pointer.

#include <stdlib.h>
#include <stdio.h> 
 void  main()
 {
    int *ptr = (int *)malloc(sizeof(int));
    // After below free call, ptr becomes a 
    // dangling pointer
    free(ptr); 
 }

Try to follow the advice you see on the screen, and first reset your master's HEAD to the commit it expects.

Then, abort the rebase again.

Considering that we have Set<String> stringSet we can use following:

Plain Java

List<String> strList = new ArrayList<>(stringSet);

Guava

List<String> strList = Lists.newArrayList(stringSet);

Apache Commons

List<String> strList = new ArrayList<>();
CollectionUtils.addAll(strList, stringSet);

Java 10 (Unmodifiable List)

List<String> strList = List.copyOf(stringSet);
List<String> strList = stringSet.stream().collect(Collectors.toUnmodifiableList());

Java 8 (Modifiable Lists)

import static java.util.stream.Collectors.*;
List<String> stringList1 = stringSet.stream().collect(toList());

As per the doc for the method toList()

There are no guarantees on the type, mutability, serializability, or thread-safety of the List returned; if more control over the returned List is required, use toCollection(Supplier).

So if we need a specific implementation e.g. ArrayList we can get it this way:

List<String> stringList2 = stringSet.stream().
                              collect(toCollection(ArrayList::new));

Java 8 (Unmodifiable Lists)

We can make use of Collections::unmodifiableList method and wrap the list returned in previous examples. We can also write our own custom method as:

class ImmutableCollector {
    public static <T> Collector<T, List<T>, List<T>> toImmutableList(Supplier<List<T>> supplier) {
            return Collector.of( supplier, List::add, (left, right) -> {
                        left.addAll(right);
                        return left;
                    }, Collections::unmodifiableList);
        }
}

And then use it as:

List<String> stringList3 = stringSet.stream()
             .collect(ImmutableCollector.toImmutableList(ArrayList::new)); 

Another possibility is to make use of collectingAndThen method which allows some final transformation to be done before returning result:

    List<String> stringList4 = stringSet.stream().collect(collectingAndThen(
      toCollection(ArrayList::new),Collections::unmodifiableList));

One point to note is that the method Collections::unmodifiableList returns an unmodifiable view of the specified list, as per doc. An unmodifiable view collection is a collection that is unmodifiable and is also a view onto a backing collection. Note that changes to the backing collection might still be possible, and if they occur, they are visible through the unmodifiable view. But the collector method Collectors.unmodifiableList returns truly immutable list in Java 10.

You can use this example and change it's implementation like this:

[self enumerateAttribute:NSParagraphStyleAttributeName
                 inRange:NSMakeRange(0, self.length)
                 options:0
              usingBlock:^(id  _Nullable value, NSRange range, BOOL * _Nonnull stop) {
                  NSMutableParagraphStyle *paragraphStyle = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];

                  //add your specific settings for paragraph
                  //...
                  //...

                  [self removeAttribute:NSParagraphStyleAttributeName range:range];
                  [self addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:range];
              }];

If you want to get any parent by any child control you can use this code, and when you find the UserControl/Form/Panel or others you can call funnctions or set/get values:

Control myControl= this;
while (myControl.Parent != null)
{

    if (myControl.Parent!=null)
    {
        myControl = myControl.Parent;
        if  (myControl.Name== "MyCustomUserControl")
        {
            ((MyCustomUserControl)myControl).lblTitle.Text = "FOUND IT";
        }
    }

}

if your files contain headers and you want remove them in the output file, you can use:

for f in `ls *.txt`; do sed '2,$!d' $f >> 0.out; done

Better yet, use union to grab all the rows you want to delete, then delete them all at once. The rows need not be continuous.

dim rng as range
dim rDel as range

for each rng in {the range you're searching}
   if {Conditions to be met} = true then
      if not rDel is nothing then
         set rDel = union(rng,rDel)
      else
         set rDel = rng
      end if
   end if
 next
 
 rDel.entirerow.delete

That way you don't have to worry about sorting or things being at the bottom.

Probably the simplest way to do it is to create a delegate and then BeginInvoke, followed by a wait at some time in the future, and an EndInvoke.

public bool Foo(){
    Thread.Sleep(100000); // Do work
    return true;
}

public SomeMethod()
{
    var fooCaller = new Func<bool>(Foo);
    // Call the method asynchronously
    var asyncResult = fooCaller.BeginInvoke(null, null);

    // Potentially do other work while the asynchronous method is executing.

    // Finally, wait for result
    asyncResult.AsyncWaitHandle.WaitOne();
    bool fooResult = fooCaller.EndInvoke(asyncResult);

    Console.WriteLine("Foo returned {0}", fooResult);
}

The 'find' method can be used to get all child inputs of a container that has already been cached to save looking it up again (whereas the 'children' method will only get the immediate children). e.g.

var panel= $("#panel");
var inputs = panel.find("input");

Port 80

What I do on my cloud instances is I redirect port 80 to port 3000 with this command:

sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 3000

Then I launch my Node.js on port 3000. Requests to port 80 will get mapped to port 3000.

You should also edit your /etc/rc.local file and add that line minus the sudo. That will add the redirect when the machine boots up. You don't need sudo in /etc/rc.local because the commands there are run as root when the system boots.

Logs

Use the forever module to launch your Node.js with. It will make sure that it restarts if it ever crashes and it will redirect console logs to a file.

Launch on Boot

Add your Node.js start script to the file you edited for port redirection, /etc/rc.local. That will run your Node.js launch script when the system starts.

Digital Ocean & other VPS

This not only applies to Linode, but Digital Ocean, AWS EC2 and other VPS providers as well. However, on RedHat based systems /etc/rc.local is /ect/rc.d/local.

Best practice it to list your columns so you're independent of table changes (new column or column order etc)

insert into table1 (field1, field3)  values (5,10)

However, if you don't want to do this, use the DEFAULT keyword

insert into table1 values (5, DEFAULT, 10, DEFAULT)

Swift is statically typed so the performSelector: methods are to fall by the wayside.

Instead, use GCD to dispatch a suitable block to the relevant queue — in this case it'll presumably be the main queue since it looks like you're doing UIKit work.

EDIT: the relevant performSelector: is also notably missing from the Swift version of the NSRunLoop documentation ("1 Objective-C symbol hidden") so you can't jump straight in with that. With that and its absence from the Swiftified NSObject I'd argue it's pretty clear what Apple is thinking here.

Make sure to remove any previous 'localhost' certificates as those could conflict with the one generated by IIS Express. I had this same error (ERR_SSL_PROTOCOL_ERROR), and it took me many hours to finally figure it out after trying out many many "solutions". My mistake was that I had created my own 'localhost' certificate and there were two of them. I had to delete both and have IIS Express recreate it.

Here is how you can check for and remove 'localhost' certificate:

• On Start, type ? mmc.exe
• File ? Add/Remove Snap-in...
• Select Certificates ? Add> ? Computer account ? Local computer
• Check under Certificates > Personal > Certificates
• Make sure the localhost certificate that exist has a friendly name "IIS Express Development Certificate". If not, delete it. Or if multiple, delete all.

On Visual Studio, select project and under property tab, enable SSL=true. Save, Build and Run. IIS Express will generate a new 'localhost' certificate.

Note: If it doesn't work, try these: make sure to disable IIS Express on VS project and stopping all running app on it prior to removing 'localhost' certificate. Also, you can go to 'control panel > programs' and Repair IIS Express.

1. Go to android/build.gradle, change

   classpath 'com.android.tools.build:gradle:2.2.3' to

   classpath 'com.android.tools.build:gradle:1.2.3'

2. Then, go to android/gradle/wrapper/gradle-wrapper.properties, change distributionURL to https://services.gradle.org/distributions/gradle-2.2-all.zip

3. Run again.

After reading your data in via a textConnection, the following seems to work:

format(dat$date, format="%Y-%m-%d")

setup.py is designed to be run from the command line. You'll need to open your command prompt (In Windows 7, hold down shift while right-clicking in the directory with the setup.py file. You should be able to select "Open Command Window Here").

From the command line, you can type

python setup.py --help

...to get a list of commands. What you are looking to do is...

python setup.py install

You can make use of java.util.Date instead of Timestamp :

String timeStamp = new SimpleDateFormat("yyyy.MM.dd.HH.mm.ss").format(new Date());

This seems weird, but you can try setting vertical-align: top in the CSS for the inputs. That fixes it in IE8, at least.

cvWaitKey(0) stops your program until you press a button.

cvWaitKey(10) doesn't stop your program but wake up and alert to end your program when you press a button. Its used into loops because cvWaitkey doesn't stop loop.

Normal use

char k;

k=cvWaitKey(0);

if(k == 'ESC')

with k you can see what key was pressed.

Just because @MartinCapodici 's comment is awesome I write here as an answer to give visibility.

All clockwise:

• WPF start West (left->top->right->bottom)
• Netscape (ie CSS) start North (top->right->bottom->left)

Write a class A, that contains of an array of class B. Class B should have an id property and a value property. Deserialize the xml to class A. Convert the array in A to the wanted dictionary.

To serialize the dictionary convert it to an instance of class A, and serialize...

Everyone should note that there seems to be a bug in XCode 6.3 (Beta and GM) that is aggravating this problem.

I have iOS 8.3 installed on my device. Setting the build target to iOS <= 8.3 did not help. Nor did any of the other solutions posted.

What worked for me:

Go to the Product Menu > Destination and select your device. It will be listed under "Ineligible", but you will still be able to select it. After doing this, I was able to build and deploy to my device.

An XSD is a formal contract that specifies how an XML document can be formed. It is often used to validate an XML document, or to generate code from.

Tilde expansion is a shell thing. Write the proper pathname (probably /home/yourusername/Desktop/etcetcetc) or use
process.env.HOME + '/Desktop/blahblahblah'

I've used this (or very similar) code to add several TextViews to a LinearLayout:

// Quick & dirty pre-made list of text labels...
String names[] = {"alpha", "beta", "gamma", "delta", "epsilon"};
int namesLength = 5;

// Create a LayoutParams...
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
    LinearLayout.LayoutParams.WRAP_CONTENT, 
    LinearLayout.LayoutParams.FILL_PARENT);

// Get existing UI containers...
LinearLayout nameButtons = (LinearLayout) view.findViewById(R.id.name_buttons);
TextView label = (TextView) view.findViewById(R.id.master_label);

TextView tv;

for (int i = 0; i < namesLength; i++) {
    // Grab the name for this "button"
    final String name = names[i];

    tv = new TextView(context);
    tv.setText(name);

    // TextViews CAN have OnClickListeners
    tv.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            label.setText("Clicked button for " + name); 
        }
    });

    nameButtons.addView(tv, params);
}

The main difference between this and dicklaw795's code is it doesn't set() and re-get() the ID for each TextView--I found it unnecessary, although I may need it to later identify each button in a common handler routine (e.g. one called by onClick() for each TextView).

Built a modal popup example using syarul's jsFiddle link. Here is the updated fiddle.

Created an angular directive called modal and used in html. Explanation:-

HTML

<div ng-controller="MainCtrl" class="container">
  <button ng-click="toggleModal('Success')" class="btn btn-default">Success</button>
  <button ng-click="toggleModal('Remove')" class="btn btn-default">Remove</button>
  <button ng-click="toggleModal('Deny')" class="btn btn-default">Deny</button>
  <button ng-click="toggleModal('Cancel')" class="btn btn-default">Cancel</button>
  <modal visible="showModal">
      Any additional data / buttons
  </modal>
</div>

On button click toggleModal() function is called with the button message as parameter. This function toggles the visibility of popup. Any tags that you put inside will show up in the popup as content since ng-transclude is placed on modal-body in the directive template.

JS

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

mymodal.controller('MainCtrl', function ($scope) {
    $scope.showModal = false;
    $scope.buttonClicked = "";
    $scope.toggleModal = function(btnClicked){
        $scope.buttonClicked = btnClicked;
        $scope.showModal = !$scope.showModal;
    };
  });

mymodal.directive('modal', function () {
    return {
      template: '<div class="modal fade">' + 
          '<div class="modal-dialog">' + 
            '<div class="modal-content">' + 
              '<div class="modal-header">' + 
                '<button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>' + 
                '<h4 class="modal-title">{{ buttonClicked }} clicked!!</h4>' + 
              '</div>' + 
              '<div class="modal-body" ng-transclude></div>' + 
            '</div>' + 
          '</div>' + 
        '</div>',
      restrict: 'E',
      transclude: true,
      replace:true,
      scope:true,
      link: function postLink(scope, element, attrs) {
        scope.title = attrs.title;

        scope.$watch(attrs.visible, function(value){
          if(value == true)
            $(element).modal('show');
          else
            $(element).modal('hide');
        });

        $(element).on('shown.bs.modal', function(){
          scope.$apply(function(){
            scope.$parent[attrs.visible] = true;
          });
        });

        $(element).on('hidden.bs.modal', function(){
          scope.$apply(function(){
            scope.$parent[attrs.visible] = false;
          });
        });
      }
    };
  });

Other values are 'A' for attribute

<div modal>

'C' for class (not preferable in our case because modal is already a class in bootstrap.css)

<div class="modal">

I know it was not available at the time, but now you could also use Anaconda navigator to install a specific version of packages in the environments tab.

int b;
double a;
a=3669.0;
b=a;
printf("b=%d",b);

this code gives the output as b=3669 only you check it clearly.

Walkthrough on using MySQL's LOAD DATA command:

1. Create your table:

   CREATE TABLE foo(myid INT, mymessage VARCHAR(255), mydecimal DECIMAL(8,4));
   

2. Create your tab delimited file (note there are tabs between the columns):

   1   Heart disease kills     1.2
   2   one out of every two    2.3
   3   people in America.      4.5
   

3. Use the load data command:

   LOAD DATA LOCAL INFILE '/tmp/foo.txt' 
   INTO TABLE foo COLUMNS TERMINATED BY '\t';
   

   If you get a warning that this command can't be run, then you have to enable the --local-infile=1 parameter described here: How can I correct MySQL Load Error

4. The rows get inserted:

   Query OK, 3 rows affected (0.00 sec)
   Records: 3  Deleted: 0  Skipped: 0  Warnings: 0
   

5. Check if it worked:

   mysql> select * from foo;
   +------+----------------------+-----------+

How to specify which columns to load your text file columns into:

Like this:

LOAD DATA LOCAL INFILE '/tmp/foo.txt' INTO TABLE foo
FIELDS TERMINATED BY '\t' LINES TERMINATED BY '\n'
(@col1,@col2,@col3) set myid=@col1,mydecimal=@col3;

The file contents get put into variables @col1, @col2, @col3. myid gets column 1, and mydecimal gets column 3. If this were run, it would omit the second row:

mysql> select * from foo;
+------+-----------+-----------+
| myid | mymessage | mydecimal |
+------+-----------+-----------+
|    1 | NULL      |    1.2000 |
|    2 | NULL      |    2.3000 |
|    3 | NULL      |    4.5000 |
+------+-----------+-----------+
3 rows in set (0.00 sec)

You just have to edit de app.php file in config directory Just find next lines

/*
|--------------------------------------------------------------------------
| Application Timezone
|--------------------------------------------------------------------------
|
| Here you may specify the default timezone for your application, which
| will be used by the PHP date and date-time functions. We have gone
| ahead and set this to a sensible default for you out of the box.
|
*/

'timezone' => 'UTC',

And.. chage it for:

'timezone' => 'Europe/Paris',

I think you may be able to do this with the metaclass. Since the metaclass can be like a class for the class (if that makes sense). I know you can assign a __call__() method to the metaclass to override calling the class, MyClass(). I wonder if using the property decorator on the metaclass operates similarly. (I haven't tried this before, but now I'm curious...)

[update:]

Wow, it does work:

class MetaClass(type):    
    def getfoo(self):
        return self._foo
    foo = property(getfoo)

    @property
    def bar(self):
        return self._bar

class MyClass(object):
    __metaclass__ = MetaClass
    _foo = 'abc'
    _bar = 'def'

print MyClass.foo
print MyClass.bar

Note: This is in Python 2.7. Python 3+ uses a different technique to declare a metaclass. Use: class MyClass(metaclass=MetaClass):, remove __metaclass__, and the rest is the same.

You can edit it. The content of the file is literally "Deny from all" which is an Apache directive: http://httpd.apache.org/docs/2.2/mod/mod_authz_host.html#deny

We can use the angular.element(document).ready() method to attach callbacks for when the document is ready. We can simply attach the callback in the controller like so:

angular.module('MyApp', [])

.controller('MyCtrl', [function() {
    angular.element(document).ready(function () {
        document.getElementById('msg').innerHTML = 'Hello';
    });
}]);

It is difficult to say how the memory allocation will affect your speed. It depends on the garbage collection algorithm the JVM is using. For example if your garbage collector needs to pause to do a full collection, then if you have 10 more memory than you really need then the collector will have 10 more garbage to clean up.

If you are using java 6 you can use the jconsole (in the bin directory of the jdk) to attach to your process and watch how the collector is behaving. In general the collectors are very smart and you won't need to do any tuning, but if you have a need there are numerous options you have use to further tune the collection process.

1. add https://momentjs.com/downloads/moment-with-locales.js to your html page
2. var todayDate = moment().format('DD-MM-YYYY');//to get today date 06/03/2018 if you want to add extra day to your current date then
3. var dueDate = moment().add(15,'days').format('DD-MM-YYYY')// to add 15 days to current date..

point 2 and 3 are using in your jquery code...

Combining Saurabh Chandra Patel's answer with Molecular Man's observation, you should have something like this:

JSON.parse('{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}');

/^[a-zA-Z]*$/

Change the * to + if you don't want to allow empty matches.

References:

Character classes ([...]), Anchors (^ and $), Repetition (+, *)

The / are just delimiters, it denotes the start and the end of the regex. One use of this is now you can use modifiers on it.

Just as a build on @markE's answer—if you want to create a local server. You won't have this error on a local server.

If you have PHP installed on your computer:

1. Open up your terminal/cmd
2. Navigate into the folder where your website files are
3. While in this folder, run the command php -S localhost:3000 ? Notice the capital 'S'
4. Open up your browser and in the URL bar go to localhost:3000. Your website should be running there.

or

If you have Node.js installed on your computer:

1. Open up your terminal/cmd
2. Navigate into the folder where your website files are
3. While in this folder, run the command npm init -y
4. Run npm install live-server -g or sudo npm install live-server -g on a mac
5. Run live-server and it should automatically open up a new tab in the browser with your website open.

Note: remember to have an index.html file in the root of your folder or else you might have some issues.

As you are reading a book about NLTK it would be interesting you read about MaxEnt Classifier Module http://www.nltk.org/api/nltk.classify.html#module-nltk.classify.maxent

For text mining classification the steps could be: pre-processing (tokenization, steaming, feature selection with Information Gain ...), transformation to numeric (frequency or TF-IDF) (I think that this is the key step to understand when using text as input to a algorithm that only accept numeric) and then classify with MaxEnt, sure this is just an example.

If you're not using gradle (creating a project from an APK, for instance), this can be done through the Android Studio UI (as of version 3.3.2):

• Right-click the project root directory, pick Open Module Settings
• Hit the + Add Content Root button (center right)
• Add your path and hit OK

In my experience (with native code), as long as your .so's are built with debug symbols and from the same absolute paths, breakpoints added in source files will be automatically recognized.

Eclipse doesn't pull the tooltips from the javadoc location. It only uses the javadoc location to prepend to the link if you say open in browser, you need to download and attach the source for the JDK in order to get the tooltips. For all the JARs under the JRE you should have the following for the javadoc location: http://java.sun.com/javase/6/docs/api/. For resources.jar, rt.jar, jsse.jar, jce.jar and charsets.jar you should attach the source available here.

Tims answer seems to me as misleading. Especially when urllib2 does not return expected code. For example this Error will be fatal (believe or not - it is not uncommon one when downloading urls):

AttributeError: 'URLError' object has no attribute 'code'

Fast, but maybe not the best solution would be code using nested try/except block:

import urllib2
try:
    urllib2.urlopen("some url")
except urllib2.HTTPError, err:
    try:
        if err.code == 404:
            # Handle the error
        else:
            raise
    except:
        ...

More information to the topic of nested try/except blocks Are nested try/except blocks in python a good programming practice?

There are a few existing resources you might check:

1. Properly Package Your Java Classes
2. Spring 2.5 Architecture
3. Java Tutorial - Naming a Package
4. SUN Naming Conventions

For what it's worth, my own personal guidelines that I tend to use are as follows:

1. Start with reverse domain, e.g. "com.mycompany".
2. Use product name, e.g. "myproduct". In some cases I tend to have common packages that do not belong to a particular product. These would end up categorized according to the functionality of these common classes, e.g. "io", "util", "ui", etc.
3. After this it becomes more free-form. Usually I group according to project, area of functionality, deployment, etc. For example I might have "project1", "project2", "ui", "client", etc.

A couple of other points:

1. It's quite common in projects I've worked on for package names to flow from the design documentation. Usually products are separated into areas of functionality or purpose already.
2. Don't stress too much about pushing common functionality into higher packages right away. Wait for there to be a need across projects, products, etc., and then refactor.
3. Watch inter-package dependencies. They're not all bad, but it can signify tight coupling between what might be separate units. There are tools that can help you keep track of this.

@Melkhiah66 You can use equals method instead of '==' method to check the equality. If you use intern() then it checks whether the object is in pool if present then returns equal else unequal. equals method internally uses hashcode and gets you the required result.

public class Demo
{
  public static void main(String[] args)
  {
              String str1 = "Jorman 14988611";
    String str2 = new StringBuffer("Jorman").append(" 14988611").toString();
    String str3 = str2.intern();
    System.out.println("str1 == str2 " + (str1 == str2));           //gives false
    System.out.println("str1 == str3 " + (str1 == str3));           //gives true
    System.out.println("str1 equals str2 " + (str1.equals(str2)));  //gives true
    System.out.println("str1 equals str3 " + (str1.equals(str3)));  //gives true
  }
}

In my opinion you should not load and use plugins you don't have to. This particular jQuery plugin doesn't give you anything since directly using the JavaScript sessionStorage object is exactly the same level of complexity. Nor, does the plugin provide some easier way to interact with other jQuery functionality. In addition the practice of using a plugin discourages a deep understanding of how something works. sessionStorage should be used only if its understood. If its understood, then using the jQuery plugin is actually MORE effort.

Consider using sessionStorage directly: https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Storage#sessionStorage

We can use the modulo (%) operator. This tells us how many remainders we have when we divide x by y - expresses as x % y. Every whole number must divide by 1, so if there is a remainder, it must not be a whole number.

This function will return a boolean, True or False, depending on whether n is a whole number.

def is_whole(n):
    return n % 1 == 0

count_smiths = (df['LastName'] == 'Smith').sum()

You can also use it like this.

fq=!id:['' TO *]

You could access the underlying array and call its tolist method:

>>> df = pd.DataFrame([[1,2,3],[3,4,5]])
>>> lol = df.values.tolist()
>>> lol
[[1L, 2L, 3L], [3L, 4L, 5L]]

After reviewing MySQL 5.7 changes, MySql stopped supporting zero values in date / datetime.

It's incorrect to use zeros in date or in datetime, just put null instead of zeros.

If you have regular arrays and nothing fancy, this will do. Remember, using array_splice() for inserting elements really means insert before the start index. Be careful when moving elements, because moving up means $targetIndex -1, where as moving down means $targetIndex + 1.

class someArrayClass
{
    private const KEEP_EXISTING_ELEMENTS = 0;

    public function insertAfter(array $array, int $startIndex, $newElements)
    {
        return $this->insertBefore($array, $startIndex + 1, $newElements);
    }

    public function insertBefore(array $array, int $startIndex, $newElements)
    {
        return array_splice($array, $startIndex, self::KEEP_EXISTING_ELEMENTS, $newElements);
    }
}
