def search(request):
if 'q' in request.GET.keys():
    message = 'You submitted: %r' % request.GET['q']
else:
    message = 'You submitted nothing!'

return HttpResponse(message)

you can use if ... in too.

Use psexec -s

The s switch will cause it to run under system account which is the same as running an elevated admin prompt. just used it to enable WinRM remotely.

If you can use a simple delimiter, a very simple oneliner is this:

for i in a,b c_s,d ; do 
  KEY=${i%,*};
  VAL=${i#*,};
  echo $KEY" XX "$VAL;
done

Hereby i is filled with character sequences like "a,b" and "c_s,d". each separated by spaces. After the do we use parameter substitution to extract the part before the comma , and the part after it.

To handle right click from the mouse, you can use the 'oncontextmenu' event. Below is an example:

 document.body.oncontextmenu=function(event) {
     alert(" Right click! ");
 };

the above code alerts some text when right click is pressed. If you do not want the default menu of the browser to appear, you can add return false; At the end of the content of the function. Thanks.

This is a fast and straightforward solution -

function chunkString (str, len) {_x000D_
  const size = Math.ceil(str.length/len)_x000D_
  const r = Array(size)_x000D_
  let offset = 0_x000D_
  _x000D_
  for (let i = 0; i < size; i++) {_x000D_
    r[i] = str.substr(offset, len)_x000D_
    offset += len_x000D_
  }_x000D_
  _x000D_
  return r_x000D_
}_x000D_
_x000D_
console.log(chunkString("helloworld", 3))_x000D_
// => [ "hel", "low", "orl", "d" ]_x000D_
_x000D_
// 10,000 char string_x000D_
const bigString = "helloworld".repeat(1000)_x000D_
console.time("perf")_x000D_
const result = chunkString(bigString, 3)_x000D_
console.timeEnd("perf")_x000D_
console.log(result)_x000D_
// => perf: 0.385 ms_x000D_
// => [ "hel", "low", "orl", "dhe", "llo", "wor", ... ]

Your system is missing the mysqlnd driver!

If you are able to install new packages on your (Debian/Ubuntu-based) server, install the driver:

sudo apt-get install php5-mysqlnd

and then restart your web server:

sudo /etc/init.d/apache2 restart

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

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

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

connection_psql.commit()
cursor_psql.close()

As per my understanding you need to show 3 tables data in one html table using asp.net with c#.

I think best you just create one dataset with 3 DataTable object.

Bind that dataset to GriView directly on page load.

Make sure that both projects have same target framework version here: right click on project -> properties -> application (tab) -> target framework

Also, make sure that the project "logger" (which you want to include in the main project) has the output type "Class Library" in: right click on project -> properties -> application (tab) -> output type

Finally, Rebuild the solution.

If I get your question correctly, you want to also know the names of the files generated inside the temporary directory? If so, try this:

import os
import tempfile

with tempfile.TemporaryDirectory() as tmp_dir:
    # generate some random files in it
     files_in_dir = os.listdir(tmp_dir)

Give the parent a style of overflow: hidden. If it is overlapping sibling elements, you will have to put it inside of a container with a fixed height/width and give that a style of overflow: hidden.

I had a slightly different problem. I worked with inputs in a modal and it drove me mad. No of the proposed solutions worked for me.

Until i found this issue: https://github.com/valor-software/ngx-bootstrap/issues/1597

This good guy gave me the hint that ngx-bootstrap modal has a focus configuration. If this configuration is not set to false, the modal will be focused after the animation and there is NO WAY to focus anything else.

Update:

To set this configuration, add the following attribute to the modal div:

[config]="{focus: false}"

Update 2:

To force the focus on the input field i wrote a directive and set the focus in every AfterViewChecked cycle as long as the input field has the class ng-untouched.

 ngAfterViewChecked() {
    // This dirty hack is needed to force focus on an input element of a modal.
    if (this.el.nativeElement.classList.contains('ng-untouched')) {
        this.renderer.invokeElementMethod(this.el.nativeElement, 'focus', []);
    }
}

class MyController < ApplicationController
    # include your helper
    include MyHelper
    # or Rails helper
    include ActionView::Helpers::NumberHelper

    def my_action
      price = number_to_currency(10000)
    end
end

In Rails 5+ simply use helpers (helpers.number_to_currency(10000))

If without '0x' prefix:

'{0:x}'.format(int(dec))

else use built-in hex() funtion.

For broken consoles like cmd.exe and HTML output you can always use:

my_unicode_string.encode('ascii','xmlcharrefreplace')

This will preserve all the non-ascii chars while making them printable in pure ASCII and in HTML.

WARNING: If you use this in production code to avoid errors then most likely there is something wrong in your code. The only valid use case for this is printing to a non-unicode console or easy conversion to HTML entities in an HTML context.

And finally, if you are on windows and use cmd.exe then you can type chcp 65001 to enable utf-8 output (works with Lucida Console font). You might need to add myUnicodeString.encode('utf8').

I was also facing the same issue with the latest version of @angular/material i.e. "^9.2.3" So I found out a solution of this. If you go to the folder of @angular/material inside node_modules, you can find a file naming index.d.ts, in that file paste the below code. With this change in the index file you will be able to import the modules using import statements from @angular/material directly. (P.S. If you face error in any of the below statements please comment that.)

1. For checking on Which Python your Jupyter Notebook is running try executig this code.

from platform import python_version print(python_version())

2. In order to run jupyter notebook from your environment activate MYenv and install jupyter notebook using command pip install jupyter notebook

then just jupyter notebook

While moopasta's answer works, it doesn't appear to allow wildcards and there is another (potentially better) option. The Chromium project has some HTTP authentication documentation that is useful but incomplete.

Specifically the option that I found best is to whitelist sites that you would like to allow Chrome to pass authentication information to, you can do this by:

• Launching Chrome with the auth-server-whitelist command line switch. e.g. --auth-server-whitelist="*example.com,*foobar.com,*baz". Downfall to this approach is that opening links from other programs will launch Chrome without the command line switch.
• Installing, enabling, and configuring the AuthServerWhitelist/"Authentication server whitelist" Group Policy or Local Group Policy. This seems like the most stable option but takes more work to setup. You can set this up locally, no need to have this remotely deployed.

Those looking to set this up for an enterprise can likely follow the directions for using Group Policy or the Admin console to configure the AuthServerWhitelist policy. Those looking to set this up for one machine only can also follow the Group Policy instructions:

1. Download and unzip the latest Chrome policy templates
2. Start > Run > gpedit.msc
3. Navigate to Local Computer Policy > Computer Configuration > Administrative Templates
4. Right-click Administrative Templates, and select Add/Remove Templates
5. Add the windows\adm\en-US\chrome.adm template via the dialog
6. In Computer Configuration > Administrative Templates > Classic Administrative Templates > Google > Google Chrome > Policies for HTTP Authentication enable and configure Authentication server whitelist
7. Restart Chrome and navigate to chrome://policy to view active policies

Environment.Exit(exitCode); //exit code 0 is a proper exit and 1 is an error

Numbers inherit from the Number constructor which doesn't have the .toLowerCase method. You can look it up as a matter of fact:

"toLowerCase" in Number.prototype; // false

After I tried algirdas' solution, my Windows crashed (Win 7 Pro 64bit) so I decided to try a different solution:

1. Start Run (Win+R)
2. Type cmd /K chcp 65001

You will get mostly what you want. To start it from the taskbar or anywhere else, make a shortcut (you can name it cmd.unicode.exe or whatever you like) and change its Target to C:\Windows\System32\cmd.exe /K chcp 65001.

Give the command SHOW CREATE TABLE whatever

Then look at the table definition.

It probably has a line like this

logtime TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,

in it. DEFAULT CURRENT_TIMESTAMP means that any INSERT without an explicit time stamp setting uses the current time. Likewise, ON UPDATE CURRENT_TIMESTAMP means that any update without an explicit timestamp results in an update to the current timestamp value.

You can control this default behavior when creating your table.

Or, if the timestamp column wasn't created correctly in the first place, you can change it.

ALTER TABLE whatevertable
     CHANGE whatevercolumn 
            whatevercolumn TIMESTAMP NOT NULL
                           DEFAULT CURRENT_TIMESTAMP 
                           ON UPDATE CURRENT_TIMESTAMP;

This will cause both INSERT and UPDATE operations on the table automatically to update your timestamp column. If you want to update whatevertable without changing the timestamp, that is,

To prevent the column from updating when other columns change

then you need to issue this kind of update.

UPDATE whatevertable
   SET something = 'newvalue',
       whatevercolumn = whatevercolumn
 WHERE someindex = 'indexvalue'

This works with TIMESTAMP and DATETIME columns. (Prior to MySQL version 5.6.5 it only worked with TIMESTAMPs) When you use TIMESTAMPs, time zones are accounted for: on a correctly configured server machine, those values are always stored in UTC and translated to local time upon retrieval.

Use String.format (or java.util.Formatter):

Timestamp timestamp = ...
String.format("%1$TD %1$TT", timestamp)

EDIT:
please see the documentation of Formatter to know what TD and TT means: click on java.util.Formatter

The first 'T' stands for:

't', 'T'    date/time   Prefix for date and time conversion characters.

and the character following that 'T':

'T'     Time formatted for the 24-hour clock as "%tH:%tM:%tS".
'D'     Date formatted as "%tm/%td/%ty". 

Adding a

  target='_top'

to my link in the facebook tab fixed the issue for me...

You can do like this

SELECT something
FROM
    (a LEFT JOIN b ON a.a_id = b.b_id) LEFT JOIN c on a.a_aid = c.c_id
WHERE a.parent_id = 'rootID'

Assuming you are correct and your id is a proper number (without any other text), you should parse the id and then add one to it:

var currentPage = parseInt($(this).attr('id'), 10);
++currentPage;

doSomething(currentPage);

without jQuery you can use

document.getElementById('text_input').setAttribute('maxlength',200);

Python’s raw strings are just a way to tell the Python interpreter that it should interpret backslashes as literal slashes. If you read strings entered by the user, they are already past the point where they could have been raw. Also, user input is most likely read in literally, i.e. “raw”.

This means the interpreting happens somewhere else. But if you know that it happens, why not escape the backslashes for whatever is interpreting it?

s = s.replace("\\", "\\\\")

(Note that you can't do r"\" as “a raw string cannot end in a single backslash”, but I could have used r"\\" as well for the second argument.)

If that doesn’t work, your user input is for some arcane reason interpreting the backslashes, so you’ll need a way to tell it to stop that.

I know this is old but none of the above solutions worked for me. After extensive debugging, I figured out the issue. The solution is setting the android:windowTranslucentStatus attribute to false in my styles.xml

One issue I found with all the existing answers is that the margins aren't preserved. This is because they all override the android:windowBackground attribute, which is responsible for margins, with a solid color. However, I did some digging in the Android SDK and found the default window background drawable, and modified it a bit to allow transparent dialogs.

First, copy /platforms/android-22/data/res/drawable/dialog_background_material.xml to your project. Or, just copy these lines into a new file:

<inset xmlns:android="http://schemas.android.com/apk/res/android"
    android:inset="16dp">
    <shape android:shape="rectangle">
        <corners android:radius="2dp" />
        <solid android:color="?attr/colorBackground" />
    </shape>
</inset>

Notice that android:color is set to ?attr/colorBackground. This is the default solid grey/white you see. To allow the color defined in android:background in your custom style to be transparent and show the transparency, all we have to do is change ?attr/colorBackground to @android:color/transparent. Now it will look like this:

<inset xmlns:android="http://schemas.android.com/apk/res/android"
    android:inset="16dp">
    <shape android:shape="rectangle">
        <corners android:radius="2dp" />
        <solid android:color="@android:color/transparent" />
    </shape>
</inset>

After that, go to your theme and add this:

<style name="MyTransparentDialog" parent="@android:style/Theme.Material.Dialog">
    <item name="android:windowBackground">@drawable/newly_created_background_name</item>
    <item name="android:background">@color/some_transparent_color</item>
</style>

Make sure to replace newly_created_background_name with the actual name of the drawable file you just created, and replace some_transparent_color with the desired transparent background.

After that all we need to do is set the theme. Use this when creating the AlertDialog.Builder:

    AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.MyTransparentDialog);

Then just build, create, and show the dialog as usual!

Service vs provider vs factory:

I am trying to keep it simple. It's all about basic JavaScript concept.

First of all, let's talk about services in AngularJS!

What is Service: In AngularJS, Service is nothing but a singleton JavaScript object which can store some useful methods or properties. This singleton object is created per ngApp(Angular app) basis and it is shared among all the controllers within current app. When Angularjs instantiate a service object, it register this service object with a unique service name. So each time when we need service instance, Angular search the registry for this service name, and it returns the reference to service object. Such that we can invoke method, access properties etc on the service object. You may have question whether you can also put properties, methods on scope object of controllers! So why you need service object? Answers is: services are shared among multiple controller scope. If you put some properties/methods in a controller's scope object , it will be available to current scope only. But when you define methods, properties on service object, it will be available globally and can be accessed in any controller's scope by injecting that service.

So if there are three controller scope, let it be controllerA, controllerB and controllerC, all will share same service instance.

<div ng-controller='controllerA'>
    <!-- controllerA scope -->
</div>
<div ng-controller='controllerB'>
    <!-- controllerB scope -->
</div>
<div ng-controller='controllerC'>
    <!-- controllerC scope -->
</div>

How to create a service?

AngularJS provide different methods to register a service. Here we will concentrate on three methods factory(..),service(..),provider(..);

Use this link for code reference

Factory function:

We can define a factory function as below.

factory('serviceName',function fnFactory(){ return serviceInstance;})

AngularJS provides 'factory('serviceName', fnFactory)' method which takes two parameter, serviceName and a JavaScript function. Angular creates service instance by invoking the function fnFactory() such as below.

var serviceInstace = fnFactory();

The passed function can define a object and return that object. AngularJS simply stores this object reference to a variable which is passed as first argument. Anything which is returned from fnFactory will be bound to serviceInstance . Instead of returning object , we can also return function, values etc, Whatever we will return , will be available to service instance.

Example:

var app= angular.module('myApp', []);
//creating service using factory method
app.factory('factoryPattern',function(){
  var data={
    'firstName':'Tom',
    'lastName':' Cruise',
    greet: function(){
      console.log('hello!' + this.firstName + this.lastName);
    }
  };

  //Now all the properties and methods of data object will be available in our service object
  return data;
});

Service Function:

service('serviceName',function fnServiceConstructor(){})

It's the another way, we can register a service. The only difference is the way AngularJS tries to instantiate the service object. This time angular uses 'new' keyword and call the constructor function something like below.

var serviceInstance = new fnServiceConstructor();

In the constructor function we can use 'this' keyword for adding properties/methods to the service object. example:

//Creating a service using the service method
var app= angular.module('myApp', []);
app.service('servicePattern',function(){
  this.firstName ='James';
  this.lastName =' Bond';
  this.greet = function(){
    console.log('My Name is '+ this.firstName + this.lastName);
  };
});

Provider function:

Provider() function is the another way for creating services. Let we are interested to create a service which just display some greeting message to the user. But we also want to provide a functionality such that user can set their own greeting message. In technical terms we want to create configurable services. How can we do this ? There must be a way, so that app could pass their custom greeting messages and Angularjs would make it available to factory/constructor function which create our services instance. In such a case provider() function do the job. using provider() function we can create configurable services.

We can create configurable services using provider syntax as given below.

/*step1:define a service */
app.provider('service',function serviceProviderConstructor(){});

/*step2:configure the service */
app.config(function configureService(serviceProvider){});

How does provider syntax internally work?

1.Provider object is created using constructor function we defined in our provider function.

var serviceProvider = new serviceProviderConstructor();

2.The function we passed in app.config(), get executed. This is called config phase, and here we have a chance to customize our service.

configureService(serviceProvider);

3.Finally service instance is created by calling $get method of serviceProvider.

serviceInstance = serviceProvider.$get()

Sample code for creating service using provide syntax:

var app= angular.module('myApp', []);
app.provider('providerPattern',function providerConstructor(){
  //this function works as constructor function for provider
  this.firstName = 'Arnold ';
  this.lastName = ' Schwarzenegger' ;
  this.greetMessage = ' Welcome, This is default Greeting Message' ;
  //adding some method which we can call in app.config() function
  this.setGreetMsg = function(msg){
    if(msg){
      this.greetMessage =  msg ;
    }
  };

  //We can also add a method which can change firstName and lastName
  this.$get = function(){
    var firstName = this.firstName;
    var lastName = this.lastName ;
    var greetMessage = this.greetMessage;
    var data={
       greet: function(){
         console.log('hello, ' + firstName + lastName+'! '+ greetMessage);
       }
    };
    return data ;
  };
});

app.config(
  function(providerPatternProvider){
    providerPatternProvider.setGreetMsg(' How do you do ?');
  }
);

Working Demo

Summary:

Factory use a factory function which return a service instance. serviceInstance = fnFactory();

Service use a constructor function and Angular invoke this constructor function using 'new' keyword for creating the service instance. serviceInstance = new fnServiceConstructor();

Provider defines a providerConstructor function, this providerConstructor function defines a factory function $get . Angular calls $get() to create the service object. Provider syntax has an added advantage of configuring the service object before it get instantiated. serviceInstance = $get();

I was getting this error when running my project from my local machine using visual studio 2017

Not one of these solutions worked for me. At the end of the day, the fix that worked for me was the following:

1. Right click on the project -> Properties -> Web -> Project Url
2. In the project Url text box, I incremented my port number by one and then clicked on Create Virtual Directory button.
3. Save your changes and then run the project again.

Sure, you can use .get_loc():

In [45]: df = DataFrame({"pear": [1,2,3], "apple": [2,3,4], "orange": [3,4,5]})

In [46]: df.columns
Out[46]: Index([apple, orange, pear], dtype=object)

In [47]: df.columns.get_loc("pear")
Out[47]: 2

although to be honest I don't often need this myself. Usually access by name does what I want it to (df["pear"], df[["apple", "orange"]], or maybe df.columns.isin(["orange", "pear"])), although I can definitely see cases where you'd want the index number.

let's take a question: Given two strings s and t, write a function to determine if t is an anagram of s.

For example, s = "anagram", t = "nagaram", return true. s = "rat", t = "car", return false.

Method 1(Using HashMap ):

public class Method1 {

    public static void main(String[] args) {
        String a = "protijayi";
        String b = "jayiproti";
        System.out.println(isAnagram(a, b ));// output => true

    }

    private static boolean isAnagram(String a, String b) {
        Map<Character ,Integer> map = new HashMap<>();
        for( char c : a.toCharArray()) {
            map.put(c,    map.getOrDefault(c, 0 ) + 1 );
        }
        for(char c : b.toCharArray()) {
            int count = map.getOrDefault(c, 0);
            if(count  == 0 ) {return false ; }
            else {map.put(c, count - 1 ) ; }
        }
        
        return true;
    }

}

Method 2 :

public class Method2 {
public static void main(String[] args) {
    String a = "protijayi";
    String b = "jayiproti";

    
    System.out.println(isAnagram(a, b));// output=> true
}

private static boolean isAnagram(String a, String b) {
   
    
    int[] alphabet = new int[26];
    for(int i = 0 ; i < a.length() ;i++) {
         alphabet[a.charAt(i) - 'a']++ ;
    }
    for (int i = 0; i < b.length(); i++) {
         alphabet[b.charAt(i) - 'a']-- ;
    }
    
    for(  int w :  alphabet ) {
         if(w != 0 ) {return false;}
    }
    return true;
    
}
}

Method 3 :

public class Method3 {
public static void main(String[] args) {
    String a = "protijayi";
    String b = "jayiproti";
    
    
    System.out.println(isAnagram(a, b ));// output => true
}

private static boolean isAnagram(String a, String b) {
    char[] ca = a.toCharArray() ;
    char[] cb = b.toCharArray();
    Arrays.sort(   ca     );
    
    Arrays.sort(   cb        );
    return Arrays.equals(ca , cb );
}
}

Method 4 :

public class AnagramsOrNot {
    public static void main(String[] args) {
        String a = "Protijayi";
        String b = "jayiProti";
        isAnagram(a, b);
    }

    private static void isAnagram(String a, String b) {
        Map<Integer, Integer> map = new LinkedHashMap<>();

        a.codePoints().forEach(code -> map.put(code, map.getOrDefault(code, 0) + 1));
        System.out.println(map);
        b.codePoints().forEach(code -> map.put(code, map.getOrDefault(code, 0) - 1));
        System.out.println(map);
        if (map.values().contains(0)) {
            System.out.println("Anagrams");
        } else {
            System.out.println("Not Anagrams");
        }
    }
}

In Python:

def areAnagram(a, b):
    if len(a) != len(b): return False
    count1 = [0] * 256
    count2 = [0] * 256
    for i in a:count1[ord(i)] += 1
    for i in b:count2[ord(i)] += 1

    for i in range(256):
        if(count1[i] != count2[i]):return False    

    return True


str1 = "Giniiii"
str2 = "Protijayi"
print(areAnagram(str1, str2))

Let's take another famous Interview Question: Group the Anagrams from a given String:

public class GroupAnagrams {
    public static void main(String[] args) {
        String a = "Gini Gina Protijayi iGin aGin jayiProti Soudipta";
        Map<String, List<String>> map = Arrays.stream(a.split(" ")).collect(Collectors.groupingBy(GroupAnagrams::sortedString));
        System.out.println("MAP => " + map);
        map.forEach((k,v) -> System.out.println(k +" and the anagrams are =>" + v ));
        /*
         Look at the Map output:
        MAP => {Giin=[Gini, iGin], Paiijorty=[Protijayi, jayiProti], Sadioptu=[Soudipta], Gain=[Gina, aGin]}
        As we can see, there are multiple Lists. Hence, we have to use a flatMap(List::stream)
        Now, Look at the output:
        Paiijorty and the anagrams are =>[Protijayi, jayiProti]
       
        Now, look at this output:
        Sadioptu and the anagrams are =>[Soudipta]
        List contains only word. No anagrams.
        That means we have to work with map.values(). List contains all the anagrams.
        
                     
        */
        String stringFromMapHavingListofLists = map.values().stream().flatMap(List::stream).collect(Collectors.joining(" "));
        System.out.println(stringFromMapHavingListofLists);
    }

    public static String sortedString(String a) {
        String sortedString = a.chars().sorted()
                .collect(StringBuilder::new, StringBuilder::appendCodePoint, StringBuilder::append).toString();

        return sortedString;

    }
    
    /*
     * The output : Gini iGin Protijayi jayiProti Soudipta Gina aGin
     * All the anagrams are side by side.
     */
}

Now to Group Anagrams in Python is again easy.We have to : Sort the lists. Then, Create a dictionary. Now dictionary will tell us where are those anagrams are( Indices of Dictionary). Then values of the dictionary is the actual indices of the anagrams.

def groupAnagrams(words):
 
    # sort each word in the list
    A = [''.join(sorted(word)) for word in words]
    dict = {}
    for indexofsamewords, names in enumerate(A):
     dict.setdefault(names, []).append(indexofsamewords)
    print(dict)
    #{'AOOPR': [0, 2, 5, 11, 13], 'ABTU': [1, 3, 4], 'Sorry': [6], 'adnopr': [7], 'Sadioptu': [8, 16], ' KPaaehiklry': [9], 'Taeggllnouy': [10], 'Leov': [12], 'Paiijorty': [14, 18], 'Paaaikpr': [15], 'Saaaabhmryz': [17], ' CNaachlortttu': [19], 'Saaaaborvz': [20]}
 
    for index in dict.values():
     print([words[i] for i in index])
 

if __name__ == '__main__':
 
    # list of words
    words = ["ROOPA","TABU","OOPAR","BUTA","BUAT" , "PAROO","Soudipta",
        "Kheyali Park", "Tollygaunge", "AROOP","Love","AOORP", "Protijayi","Paikpara","dipSouta","Shyambazaar",
        "jayiProti", "North Calcutta", "Sovabazaar"]
 
    groupAnagrams(words)
 

The Output :

['ROOPA', 'OOPAR', 'PAROO', 'AROOP', 'AOORP']
['TABU', 'BUTA', 'BUAT']
['Soudipta', 'dipSouta']
['Kheyali Park']
['Tollygaunge']
['Love']
['Protijayi', 'jayiProti']
['Paikpara']
['Shyambazaar']
['North Calcutta']
['Sovabazaar']

Another Important Anagram Question : Find the Anagram occuring Max. number of times. In the Example, ROOPA is the word which has occured maximum number of times. Hence, ['ROOPA' 'OOPAR' 'PAROO' 'AROOP' 'AOORP'] will be the final output.

from sqlite3 import collections
from statistics import mode, mean

import numpy as np


# list of words
words = ["ROOPA","TABU","OOPAR","BUTA","BUAT" , "PAROO","Soudipta",
        "Kheyali Park", "Tollygaunge", "AROOP","Love","AOORP",
         "Protijayi","Paikpara","dipSouta","Shyambazaar",
        "jayiProti", "North Calcutta", "Sovabazaar"]

print(".....Method 1....... ")

sortedwords = [''.join(sorted(word)) for word in words]
print(sortedwords)
print("...........")
LongestAnagram = np.array(words)[np.array(sortedwords) == mode(sortedwords)]
# Longest anagram 
print("Longest anagram by Method 1:")
print(LongestAnagram)

print(".....................................................")  

print(".....Method 2....... ")  

A = [''.join(sorted(word)) for word in words]

dict = {}

for indexofsamewords,samewords in  enumerate(A):
    dict.setdefault(samewords,[]).append(samewords)
#print(dict)  
#{'AOOPR': ['AOOPR', 'AOOPR', 'AOOPR', 'AOOPR', 'AOOPR'], 'ABTU': ['ABTU', 'ABTU', 'ABTU'], 'Sadioptu': ['Sadioptu', 'Sadioptu'], ' KPaaehiklry': [' KPaaehiklry'], 'Taeggllnouy': ['Taeggllnouy'], 'Leov': ['Leov'], 'Paiijorty': ['Paiijorty', 'Paiijorty'], 'Paaaikpr': ['Paaaikpr'], 'Saaaabhmryz': ['Saaaabhmryz'], ' CNaachlortttu': [' CNaachlortttu'], 'Saaaaborvz': ['Saaaaborvz']}
     
aa =  max(dict.items() , key = lambda x : len(x[1]))
print("aa => " , aa)    
word, anagrams = aa 
print("Longest anagram by Method 2:")
print(" ".join(anagrams))    

The Output :

.....Method 1....... 
['AOOPR', 'ABTU', 'AOOPR', 'ABTU', 'ABTU', 'AOOPR', 'Sadioptu', ' KPaaehiklry', 'Taeggllnouy', 'AOOPR', 'Leov', 'AOOPR', 'Paiijorty', 'Paaaikpr', 'Sadioptu', 'Saaaabhmryz', 'Paiijorty', ' CNaachlortttu', 'Saaaaborvz']

If any one want it in Java, Here is my Answer, For this you have to call Another Thread.

FINDSTR has a color bug that I described and solved at https://superuser.com/questions/1535810/is-there-a-better-way-to-mitigate-this-obscure-color-bug-when-piping-to-findstr/1538802?noredirect=1#comment2339443_1538802

To summarize that thread, the bug is that if input is piped to FINDSTR within a parenthesized block of code, inline ANSI escape colorcodes stop working in commands executed later. An example of inline colorcodes is: echo %magenta%Alert: Something bad happened%yellow% (where magenta and yellow are vars defined earlier in the .bat file as the corresponding ANSI escape colorcodes).

My initial solution was to call a do-nothing subroutine after the FINDSTR. Somehow the call or the return "resets" whatever needs to be reset.

Later I discovered another solution that presumably is more efficient: place the FINDSTR phrase within parentheses, as in the following example: echo success | ( FINDSTR /R success ) Placing the FINDSTR phrase within a nested block of code appears to isolate FINDSTR's colorcode bug so it won't affect what's outside the nested block. Perhaps this technique will solve some other undesired FINDSTR side effects too.

Agree with 2nd most vote answer that it will make big difference when using LEFT JOIN or RIGHT JOIN. Actually, the two statements below are equivalent. So you can see that AND clause is doing a filter before JOIN while the WHERE clause is doing a filter after JOIN.

SELECT *
FROM dbo.Customers AS CUS 
LEFT JOIN dbo.Orders AS ORD 
ON CUS.CustomerID = ORD.CustomerID
AND ORD.OrderDate >'20090515'

SELECT *
FROM dbo.Customers AS CUS 
LEFT JOIN (SELECT * FROM dbo.Orders WHERE OrderDate >'20090515') AS ORD 
ON CUS.CustomerID = ORD.CustomerID

You use standard syntax (using this like a method) to pick the overload, inside the class:

class Foo 
{
    private int id;
    private string name;

    public Foo() : this(0, "") 
    {
    }

    public Foo(int id, string name) 
    {
        this.id = id;
        this.name = name;
    }

    public Foo(int id) : this(id, "") 
    {
    }

    public Foo(string name) : this(0, name) 
    {
    }
}

then:

Foo a = new Foo(), b = new Foo(456,"def"), c = new Foo(123), d = new Foo("abc");

Note also:

• you can chain to constructors on the base-type using base(...)
• you can put extra code into each constructor
• the default (if you don't specify anything) is base()

For "why?":

• code reduction (always a good thing)

• necessary to call a non-default base-constructor, for example:

  SomeBaseType(int id) : base(id) {...}
  

Note that you can also use object initializers in a similar way, though (without needing to write anything):

SomeType x = new SomeType(), y = new SomeType { Key = "abc" },
         z = new SomeType { DoB = DateTime.Today };

Arrived here because my source repo had %20 in it which was creating local folders with %20 in them when using simplistic git clone <url>.

Easy solution:

git clone https://teamname.visualstudio.com/Project%20Name/_git/Repo%20Name "Repo Name"

If You are trying to access it through Data Connections in Visual Studio 2015, and getting the above Error, Then Go to Advanced and set TrustServerCertificate=True for error to go away.

dataframe[:n] - Will return first n-1 rows

I would like to share my experience with \n
I came to notice that "\n" works as-

puts "\n\n" // to provide 2 new lines

but not

p "\n\n"

also puts '\n\n'
Doesn't works.

Hope will work for you!!

git clone -b <branch> <remote_repo>

Example:

git clone -b my-branch [email protected]:user/myproject.git

With Git 1.7.10 and later, add --single-branch to prevent fetching of all branches. Example, with OpenCV 2.4 branch:

git clone -b opencv-2.4 --single-branch https://github.com/Itseez/opencv.git

In your AndroidManifest.xml add this two-line.

android:usesCleartextTraffic="true"  
<uses-library android:name="org.apache.http.legacy" android:required="false"/>

See this below code

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher"
        android:supportsRtl="true"
        android:usesCleartextTraffic="true"
        android:theme="@style/AppTheme"
        tools:ignore="AllowBackup,GoogleAppIndexingWarning">

    </application>

Git is Version Control System, created for software development, so from the whole set of modes and permissions it stores only executable bit (for ordinary files) and symlink bit. If you want to store full permissions, you need third party tool, like git-cache-meta (mentioned by VonC), or Metastore (used by etckeeper). Or you can use IsiSetup, which IIRC uses git as backend.

See Interfaces, frontends, and tools page on Git Wiki.

With a different opinion, I think the global variables might be the best choice if you are going to publish your code to npm, cuz you cannot be sure that all packages are using the same release of your code. So if you use a file for exporting a singleton object, it will cause issues here.

You can choose global, require.main or any other objects which are shared across files.

Otherwise, install your package as an optional dependency package can avoid this problem.

Please tell me if there are some better solutions.

declare @i numeric(28,5) = 12.0001


if (@i/cast(@i as int) > 1)
begin
    select 'this is not int'
end
else
begin
    select 'this is int'
end

or use this header library and write:

// |notEqaul|less|lessEqual|greater|greaterEqual
if(sweet::equal(valueA,valueB))

and don't care about signed/unsigned or different sizes

Run docker login

Push the image to docker hub

Re-create pod

This solved the problem for me. Hope it helps.

why wouldn't you also use it for C++? CDT meets every requirement you've mentioned.

I didn't use eclipse at first because I wasn't sure that it was equally good at giving me the means of developing in C++ (efficiently). Besides that, I was also convinced that there had to be better, more specialized tools available for c++ development in Linux:

and I really like that [eclipse] IDE for java, but is it any good for c++ and won't I miss out on something that is even better?

I honestly believe that, although some tools (like eclipse) are great at many things, it is best to look for other options as well (and I don't mean that for IDE's only, but in general and even in real life)...
Like in this case, vim is really great, and I would have missed out on it if I sticked to something I already knew.

You could do this:

InputStream in = new ByteArrayInputStream(string.getBytes("UTF-8"));

Note the UTF-8 encoding. You should specify the character set that you want the bytes encoded into. It's common to choose UTF-8 if you don't specifically need anything else. Otherwise if you select nothing you'll get the default encoding that can vary between systems. From the JavaDoc:

The behavior of this method when this string cannot be encoded in the default charset is unspecified. The CharsetEncoder class should be used when more control over the encoding process is required.

You can use many ports together for each project,

  php artisan serve --port=8000

  php artisan serve --port=8001   

  php artisan serve --port=8002

  php artisan serve --port=8003

for...in is useful when working on an object in JavaScript, but not for an Array, but still we can not say it's a wrong way, but it's not recommended, look at this example below using for...in loop:

let txt = "";
const person = {fname:"Alireza", lname:"Dezfoolian", age:35}; 
for (const x in person) {
    txt += person[x] + " ";
}
console.log(txt); //Alireza Dezfoolian 35 

OK, let's do it with Array now:

let txt = "";
const person = ["Alireza", "Dezfoolian", 35]; 
for (const x in person) {
   txt += person[x] + " ";
}
console.log(txt); //Alireza Dezfoolian 35 

As you see the result the same...

But let's try something, let's prototype something to Array...

Array.prototype.someoneelse = "someoneelse";

Now we create a new Array();

let txt = "";
const arr = new Array();
arr[0] = 'Alireza';
arr[1] = 'Dezfoolian';
arr[2] = 35;
for(x in arr) {
 txt += arr[x] + " ";
}
console.log(txt); //Alireza Dezfoolian 35 someoneelse

You see the someoneelse!!!... We actually looping through new Array object in this case!

So that's one of the reasons why we need to use for..in carefully, but it's not always the case...

Looks like a server issue (i.e. a "GitHub" issue).
If you look at this thread, it can happen when the git-http-backend gets a corrupted heap.(and since they just put in place a smart http support...)
But whatever the actual cause is, it may also be related with recent sporadic disruption in one of the GitHub fileserver.

Do you still see this error message? Because if you do:

• check your local Git version (and upgrade to the latest one)
• report this as a GitHub bug.

Note: the Smart HTTP Support is a big deal for those of us behind an authenticated-based enterprise firewall proxy!

From now on, if you clone a repository over the http:// url and you are using a Git client version 1.6.6 or greater, Git will automatically use the newer, better transport mechanism.
Even more amazing, however, is that you can now push over that protocol and clone private repositories as well. If you access a private repository, or you are a collaborator and want push access, you can put your username in the URL and Git will prompt you for the password when you try to access it.

Older clients will also fall back to the older, less efficient way, so nothing should break - just newer clients should work better.

So again, make sure to upgrade your Git client first.

If all else fails, like it did in my case, then just disable annotations. I started a c++11 project with own makefile but couldn't fix all the problems. Even if you disable annotations, eclipse will still be able to help you do some autocompletion. Most importantly, the debugger still works!

Just want to share what worked on my end, in case it would be able to help someone else too. Alternatively based on Paty Lustosa's answer above, please allow me to add another approach derived from this site where he used an ajax approach for the source method

http://salman-w.blogspot.ca/2013/12/jquery-ui-autocomplete-examples.html#example-3

The kicker is the resulting "string" or json format from your php script (listing.php below) that derives the result set to be shown in the autocomplete field should follow something like this:

    {"list":[
     {"value": 1, "label": "abc"},
     {"value": 2, "label": "def"},
     {"value": 3, "label": "ghi"}
    ]}

Then on the source portion of the autocomplete method:

    source: function(request, response) {
        $.getJSON("listing.php", {
            term: request.term
        }, function(data) {                     
            var array = data.error ? [] : $.map(data.list, function(m) {
                return {
                    label: m.label,
                    value: m.value
                };
            });
            response(array);
        });
    },
    select: function (event, ui) {
        $("#autocomplete_field").val(ui.item.label); // display the selected text
        $("#field_id").val(ui.item.value); // save selected id to hidden input
        return false;
    }

Hope this helps... all the best!

If you are using RichTextBox control. You can simply define the ToolTip object and show the tool-tip as the text is selected by moving the mouse inside the RichTextBox control.

    ToolTip m_ttInput = new ToolTip(); // define as member variable

    private void rtbInput_SelectionChanged(object sender, EventArgs e)
    {
        if (rtbInput.SelectedText.Length > 0) 
        {
            m_ttInput.Show(rtbInput.SelectedText.Length.ToString(), rtbInput, 1000);
        }
    }

<html>
  <style>
.selectBox{
 color:White;
}
.optionBox{
  color:black;
}

</style>
<body>
<select class = "selectBox">
  <option class = "optionBox">One</option>
  <option class = "optionBox">Two</option>
  <option class = "optionBox">Three</option>
</select>

You have the syntax wrong; there is no need to place a period inside a double-quoted string. Instead, it should be more like

$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$prefix%'");

You can confirm this by printing out the string to see that it turns out identical to the first case.

Of course it's not a good idea to simply inject variables into the query string like this because of the danger of SQL injection. At the very least you should manually escape the contents of the variable with mysql_real_escape_string, which would make it look perhaps like this:

$sql = sprintf("SELECT * FROM table WHERE the_number LIKE '%s%%'",
               mysql_real_escape_string($prefix));
$query = mysql_query($sql);

Note that inside the first argument of sprintf the percent sign needs to be doubled to end up appearing once in the result.

Starting with Firefox 65 an about:config flag exists now so console API calls like console.log() land in the output stream and thus the log file (see (https://github.com/mozilla/geckodriver/issues/284#issuecomment-458305621).

profile = new FirefoxProfile();
profile.setPreference("devtools.console.stdout.content", true);

Command go

Download and install packages and dependencies

Usage:

go get [-d] [-f] [-t] [-u] [-v] [-fix] [-insecure] [build flags] [packages]

Get downloads the packages named by the import paths, along with their dependencies. It then installs the named packages, like 'go install'.

The -d flag instructs get to stop after downloading the packages; that is, it instructs get not to install the packages.

The -f flag, valid only when -u is set, forces get -u not to verify that each package has been checked out from the source control repository implied by its import path. This can be useful if the source is a local fork of the original.

The -fix flag instructs get to run the fix tool on the downloaded packages before resolving dependencies or building the code.

The -insecure flag permits fetching from repositories and resolving custom domains using insecure schemes such as HTTP. Use with caution.

The -t flag instructs get to also download the packages required to build the tests for the specified packages.

The -u flag instructs get to use the network to update the named packages and their dependencies. By default, get uses the network to check out missing packages but does not use it to look for updates to existing packages.

The -v flag enables verbose progress and debug output.

Get also accepts build flags to control the installation. See 'go help build'.

When checking out a new package, get creates the target directory GOPATH/src/. If the GOPATH contains multiple entries, get uses the first one. For more details see: 'go help gopath'.

When checking out or updating a package, get looks for a branch or tag that matches the locally installed version of Go. The most important rule is that if the local installation is running version "go1", get searches for a branch or tag named "go1". If no such version exists it retrieves the default branch of the package.

When go get checks out or updates a Git repository, it also updates any git submodules referenced by the repository.

Get never checks out or updates code stored in vendor directories.

For more about specifying packages, see 'go help packages'.

For more about how 'go get' finds source code to download, see 'go help importpath'.

This text describes the behavior of get when using GOPATH to manage source code and dependencies. If instead the go command is running in module-aware mode, the details of get's flags and effects change, as does 'go help get'. See 'go help modules' and 'go help module-get'.

See also: go build, go install, go clean.

For example, showing verbose output,

$ go get -v github.com/capotej/groupcache-db-experiment/...
github.com/capotej/groupcache-db-experiment (download)
github.com/golang/groupcache (download)
github.com/golang/protobuf (download)

$ 

That should be simple. Try this:

var idList = new int[1, 2, 3, 4, 5];
var userProfiles = _dataContext.UserProfile.Where(e => idList.Contains(e));

Java 8 provides different utility api methods to help us sort the streams better.

If your list is a list of Integers(or Double, Long, String etc.,) then you can simply sort the list with default comparators provided by java.

List<Integer> integerList = Arrays.asList(1, 4, 3, 4, 5);

Creating comparator on fly:

integerList.stream().sorted((i1, i2) -> i1.compareTo(i2)).forEach(System.out::println);

With default comparator provided by java 8 when no argument passed to sorted():

integerList.stream().sorted().forEach(System.out::println); //Natural order

If you want to sort the same list in reverse order:

 integerList.stream().sorted(Comparator.reverseOrder()).forEach(System.out::println); // Reverse Order

If your list is a list of user defined objects, then:

List<Person> personList = Arrays.asList(new Person(1000, "First", 25, 30000),
        new Person(2000, "Second", 30, 45000),
        new Person(3000, "Third", 35, 25000));

Creating comparator on fly:

personList.stream().sorted((p1, p2) -> ((Long)p1.getPersonId()).compareTo(p2.getPersonId()))
        .forEach(person -> System.out.println(person.getName()));

Using Comparator.comparingLong() method(We have comparingDouble(), comparingInt() methods too):

personList.stream().sorted(Comparator.comparingLong(Person::getPersonId)).forEach(person -> System.out.println(person.getName()));

Using Comparator.comparing() method(Generic method which compares based on the getter method provided):

personList.stream().sorted(Comparator.comparing(Person::getPersonId)).forEach(person -> System.out.println(person.getName()));

We can do chaining too using thenComparing() method:

personList.stream().sorted(Comparator.comparing(Person::getPersonId).thenComparing(Person::getAge)).forEach(person -> System.out.println(person.getName())); //Sorting by person id and then by age.

Person class

public class Person {
    private long personId;
    private String name;
    private int age;
    private double salary;

    public long getPersonId() {
        return personId;
    }

    public void setPersonId(long personId) {
        this.personId = personId;
    }

    public Person(long personId, String name, int age, double salary) {
        this.personId = personId;
        this.name = name;
        this.age = age;

        this.salary = salary;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public double getSalary() {
        return salary;
    }

    public void setSalary(double salary) {
        this.salary = salary;
    }
}

"objectForKey will return nil if it doesn't exist." It will also return nil if it does exist and it is either an integer or a boolean with a value of zero (i.e. FALSE or NO for the boolean).

I've tested this in the simulator for both 5.1 and 6.1. This means that you cannot really test for either integers or booleans having been set by asking for "the object". You can get away with this for integers if you don't mind treating "not set" as if it were "set to zero".

The people who already tested this appear to have been fooled by the false negative aspect, i.e. testing this by seeing if objectForKey returns nil when you know the key hasn't been set but failing to notice that it also returns nil if the key has been set but has been set to NO.

For my own problem, that sent me here, I just ended up changing the semantics of my boolean so that my desired default was in congruence with the value being set to NO. If that's not an option, you'll need to store as something other than a boolean and make sure that you can tell the difference between YES, NO, and "not set."

The map function can be very useful here. Using map we can apply any function to each element of an iterable.

Python 3.x

>>> def my_mul(x,y):
...     return x*y
...
>>> a = [1,2,3,4]
>>> b = [2,3,4,5]
>>>
>>> list(map(my_mul,a,b))
[2, 6, 12, 20]
>>>

Of course:

map(f, iterable)

is equivalent to

[f(x) for x in iterable]

So we can get our solution via:

>>> [my_mul(x,y) for x, y in zip(a,b)]
[2, 6, 12, 20]
>>>

In Python 2.x map() means: apply a function to each element of an iterable and construct a new list. In Python 3.x, map construct iterators instead of lists.

Instead of my_mul we could use mul operator

Python 2.7

>>>from operator import mul # import mul operator
>>>a = [1,2,3,4]
>>>b = [2,3,4,5]
>>>map(mul,a,b)
[2, 6, 12, 20]
>>>

Python 3.5+

>>> from operator import mul
>>> a = [1,2,3,4]
>>> b = [2,3,4,5]
>>> [*map(mul,a,b)]
[2, 6, 12, 20]
>>>

Please note that since map() constructs an iterator we use * iterable unpacking operator to get a list. The unpacking approach is a bit faster then the list constructor:

>>> list(map(mul,a,b))
[2, 6, 12, 20]
>>>

All the answers here supply values with powers of 10. Here is a format using proper SI units (multiples of 1024, i.e. Mebibytes, Gibibytes, and Tebibytes):

[>1099511627776]#.##,,,," TiB";[>1073741824]#.##,,," GiB";0.##,," MiB"

This supports MiB, GiB, and TiB showing two decimal places.

There are quite a few elements of the $.Ajax() that can cause issues if they are not defined correctly. I would suggest rewritting your javascript in its most basic form, you will most likely find that it works fine.

Script example:

$.ajax({
    type: "POST",
    url: '/Default.aspx/TestMethod',
    data: '{message: "HAI" }',
    contentType: "application/json; charset=utf-8",
    success: function (data) {
        console.log(data);
    },
    failure: function (response) {
        alert(response.d);
    }
});

WebMethod example:

[WebMethod]
public static string TestMethod(string message)
{
     return "The message" + message;
}

You can simply use the indexOf method on the input string:

function hasWhiteSpace(s) {
  return s.indexOf(' ') >= 0;
}

Or you can use the test method, on a simple RegEx:

function hasWhiteSpace(s) {
  return /\s/g.test(s);
}

This will also check for other white space characters like Tab.

Similar to Pablo's answer above, but a shade cleaner :

str[1..-1]

Will return the array from 1 to the last character.

'Hello World'[1..-1]
 => "ello World"

Why not just do it like this:

Select Case parameter     
   Case "userID"                
      ' does something here.        
   Case "packageID"                
      ' does something here.        
   Case "mvrType"                 
      If otherFactor Then                         
         ' does something here.                 
      Else                         
         ' do processing originally part of GoTo here
         Exit Select  
      End If      
End Select

I'm not sure if not having a case else at the end is a big deal or not, but it seems like you don't really need the go to if you just put it in the else statement of your if.

Another version...

Use strtol, wrapping it inside a simple function to hide its complexity :

inline bool isInteger(const std::string & s)
{
   if(s.empty() || ((!isdigit(s[0])) && (s[0] != '-') && (s[0] != '+'))) return false;

   char * p;
   strtol(s.c_str(), &p, 10);

   return (*p == 0);
}

Why strtol ?

As far as I love C++, sometimes the C API is the best answer as far as I am concerned:

• using exceptions is overkill for a test that is authorized to fail
• the temporary stream object creation by the lexical cast is overkill and over-inefficient when the C standard library has a little known dedicated function that does the job.

How does it work ?

strtol seems quite raw at first glance, so an explanation will make the code simpler to read :

strtol will parse the string, stopping at the first character that cannot be considered part of an integer. If you provide p (as I did above), it sets p right at this first non-integer character.

My reasoning is that if p is not set to the end of the string (the 0 character), then there is a non-integer character in the string s, meaning s is not a correct integer.

The first tests are there to eliminate corner cases (leading spaces, empty string, etc.).

This function should be, of course, customized to your needs (are leading spaces an error? etc.).

Sources :

See the description of strtol at: http://en.cppreference.com/w/cpp/string/byte/strtol.

See, too, the description of strtol's sister functions (strtod, strtoul, etc.).

Function:

function appendArray(form_data, values, name){
    if(!values && name)
        form_data.append(name, '');
    else{
        if(typeof values == 'object'){
            for(key in values){
                if(typeof values[key] == 'object')
                    appendArray(form_data, values[key], name + '[' + key + ']');
                else
                    form_data.append(name + '[' + key + ']', values[key]);
            }
        }else
            form_data.append(name, values);
    }

    return form_data;
}

Use:

var form = document.createElement('form');// or document.getElementById('my_form_id');
var formdata = new FormData(form);

appendArray(formdata, {
    sefgusyg: {
        sujyfgsujyfsg: 'srkisgfisfsgsrg',
    },
    test1: 5,
    test2: 6,

call it From your activity:

Regular expression for matching everything after "net" and before ".php":

$pattern = "net([a-zA-Z0-9_]*)\.php"; 

In the above regular expression, you can find the matching group of characters enclosed by "()" to be what you are looking for.

Hope it's useful.

Use case:

 sesssionStorage.setObj(1,{date:Date.now(),action:'save firstObject'});
 sesssionStorage.setObj(2,{date:Date.now(),action:'save 2nd object'}); 
 //Query first object
  sesssionStorage.getObj(1)
  //Retrieve date created of 2nd object
  new Date(sesssionStorage.getObj(1).date)

API

Storage.prototype.setObj = function(key, obj) {

        return this.setItem(key, JSON.stringify(obj))
    };
    
    Storage.prototype.getObj = function(key) {
        return JSON.parse(this.getItem(key))
    };

How to specify 64 bit integers in c

Going against the usual good idea to appending LL.

Appending LL to a integer constant will insure the type is at least as wide as long long. If the integer constant is octal or hex, the constant will become unsigned long long if needed.

If ones does not care to specify too wide a type, then LL is OK. else, read on.

long long may be wider than 64-bit.

Today, it is rare that long long is not 64-bit, yet C specifies long long to be at least 64-bit. So by using LL, in the future, code may be specifying, say, a 128-bit number.

C has Macros for integer constants which in the below case will be type int_least64_t

#include <stdint.h>
#include <inttypes.h>

int main(void) {
  int64_t big = INT64_C(9223372036854775807);
  printf("%" PRId64 "\n", big);
  uint64_t jenny = INT64_C(0x08675309) << 32;  // shift was done on at least 64-bit type 
  printf("0x%" PRIX64 "\n", jenny);
}

output

9223372036854775807
0x867530900000000

Worth to note, you will probably use those lots more than in similar concepts in relational world (composite keys).

Example - suppose you have to find last N users who recently joined user group X. How would you do this efficiently given reads are predominant in this case? Like that (from offical Cassandra guide):

CREATE TABLE group_join_dates (
    groupname text,
    joined timeuuid,
    join_date text,
    username text,
    email text,
    age int,
    PRIMARY KEY ((groupname, join_date), joined)
) WITH CLUSTERING ORDER BY (joined DESC)

Here, partitioning key is compound itself and the clustering key is a joined date. The reason why a clustering key is a join date is that results are already sorted (and stored, which makes lookups fast). But why do we use a compound key for partitioning key? Because we always want to read as few partitions as possible. How putting join_date in there helps? Now users from the same group and the same join date will reside in a single partition! This means we will always read as few partitions as possible (first start with the newest, then move to older and so on, rather than jumping between them).

In fact, in extreme cases you would also need to use the hash of a join_date rather than a join_date alone - so that if you query for last 3 days often those share the same hash and therefore are available from same partition!

The above solutions work fine for most cases. However, if you also need to remove all traces of that file (ie sensitive data such as passwords), you will also want to remove it from your entire commit history, as the file could still be retrieved from there.

Here is a solution that removes all traces of the file from your entire commit history, as though it never existed, yet keeps the file in place on your system.

https://help.github.com/articles/remove-sensitive-data/

You can actually skip to step 3 if you are in your local git repository, and don't need to perform a dry run. In my case, I only needed steps 3 and 6, as I had already created my .gitignore file, and was in the repository I wanted to work on.

To see your changes, you may need to go to the GitHub root of your repository and refresh the page. Then navigate through the links to get to an old commit that once had the file, to see that it has now been removed. For me, simply refreshing the old commit page did not show the change.

It looked intimidating at first, but really, was easy and worked like a charm ! :-)

I think there is no out-of-the-box support for that in VS Code.

You can install a plugin to give you similar functionality. Eg.:

https://marketplace.visualstudio.com/items?itemName=micnil.vscode-checkpoints

Or the more famous:

https://marketplace.visualstudio.com/items?itemName=xyz.local-history

Some details may need to be configured: The VS Code search gets confused sometimes because of additional folders created by this type of plugins. You can configure it to ignore such folders or change their locations (adding such folders to your .gitignore file also solves this problem).

You can use Path.GetFullPath for most of the case. But if you want to get the path also in the case of the file name is relatively located then you can use the below generic method:

string GetPath(string filePath)
{
  return Path.GetDirectoryName(Path.GetFullPath(filePath))
}

For example:

GetPath("C:\Temp\Filename.txt") return "C:\Temp\"

GetPath("Filename.txt") return current working directory like "C:\Temp\"

It turns out that you can create 32-bit ODBC connections using C:\Windows\SysWOW64\odbcad32.exe. My solution was to create the 32-bit ODBC connection as a System DSN. This still didn't allow me to connect to it since .NET couldn't look it up. After significant and fruitless searching to find how to get the OdbcConnection class to look for the DSN in the right place, I stumbled upon a web site that suggested modifying the registry to solve a different problem.

I ended up creating the ODBC connection directly under HKLM\Software\ODBC. I looked in the SysWOW6432 key to find the parameters that were set up using the 32-bit version of the ODBC administration tool and recreated this in the standard location. I didn't add an entry for the driver, however, as that was not installed by the standard installer for the app either.

After creating the entry (by hand), I fired up my windows service and everything was happy.

Like @Franz answer you can also do it with a select. For example:

<select>
  <option></option>
  <option value="Yes">Yes</option>
  <option value="No">No</option>
</select>

With this you can also give a concrete value that will be send with the form, I think that with javascript indeterminate version of checkbox, it will send the underline value of the checkbox.

At least, you can use it as a callback when javascript is disabled. For example, give it an id and in the load event change it to the javascript version of the checkbox with indeterminate status.

#include <algorithm>        // std::search
#include <string>
using std::search; using std::count; using std::string;

int main() {
    string mystring = "The needle in the haystack";
    string str = "needle";
    string::const_iterator it;
    it = search(mystring.begin(), mystring.end(), 
                str.begin(), str.end()) != mystring.end();

    // if string is found... returns iterator to str's first element in mystring
    // if string is not found... returns iterator to mystring.end()

if (it != mystring.end())
    // string is found
else
    // not found

return 0;
}

IN LARAVEL 5.2 AND UP:

Write your usual code between the opening and closing PHP statements.

@php

This is a method for converting a svg picture to a gif using standard php GD tools

1) You put the image into a canvas element in the browser:

<canvas id=myCanvas></canvas>

<script>
var Key='picturename'
var canvas = document.getElementById('myCanvas');
var context = canvas.getContext('2d');
base_image = new Image();
base_image.src = myimage.svg;
base_image.onload = function(){

    //get the image info as base64 text string

    var dataURL = canvas.toDataURL();
    //Post the image (dataURL) to the server using jQuery post method
    $.post('ProcessPicture.php',{'TheKey':Key,'image': dataURL ,'h': canvas.height,'w':canvas.width,"stemme":stemme } ,function(data,status){ alert(data+' '+status) });
}
</script>    

And then convert it at the server (ProcessPicture.php) from (default) png to gif and save it. (you could have saved as png too then use imagepng instead of image gif):

//receive the posted data in php
$pic=$_POST['image'];
$Key=$_POST['TheKey'];
$height=$_POST['h'];
$width=$_POST['w'];
$dir='../gif/'
$gifName=$dir.$Key.'.gif';
 $pngName=$dir.$Key.'.png';

//split the generated base64 string before the comma. to remove the 'data:image/png;base64, header  created by and get the image data
$data = explode(',', $pic);
$base64img = base64_decode($data[1]);
$dimg=imagecreatefromstring($base64img); 

//in order to avoid copying a black figure into a (default) black background you must create a white background

$im_out = ImageCreateTrueColor($width,$height);
$bgfill = imagecolorallocate( $im_out, 255, 255, 255 );
imagefill( $im_out, 0,0, $bgfill );

//Copy the uploaded picture in on the white background
ImageCopyResampled($im_out, $dimg ,0, 0, 0, 0, $width, $height,$width, $height);

//Make the gif and png file 
imagegif($im_out, $gifName);
imagepng($im_out, $pngName);

the problem here is that by using the apostrophes you are setting the value being passed to be a string, when in fact, as @Shijo stated from the documentation, the function is expecting a label or list, but not a string! If the list contains each of the name of the columns beings passed for both the left and right dataframe, then each column-name must individually be within apostrophes. With what has been stated, we can understand why this is inccorect:

new_df = pd.merge(A_df, B_df,  how='left', left_on='[A_c1,c2]', right_on = '[B_c1,c2]')

And this is the correct way of using the function:

new_df = pd.merge(A_df, B_df,  how='left', left_on=['A_c1','c2'], right_on = ['B_c1','c2'])

Why don't you use spring's TransactionTemplate to programmatically control transactions? You could also restructure your code so that each "transaction block" has it's own @Transactional method, but given that it's a test I would opt for programmatic control of your transactions.

Also note that the @Transactional annotation on your runnable won't work (unless you are using aspectj) as the runnables aren't managed by spring!

@RunWith(SpringJUnit4ClassRunner.class)
//other spring-test annotations; as your database context is dirty due to the committed transaction you might want to consider using @DirtiesContext
public class TransactionTemplateTest {

@Autowired
PlatformTransactionManager platformTransactionManager;

TransactionTemplate transactionTemplate;

@Before
public void setUp() throws Exception {
    transactionTemplate = new TransactionTemplate(platformTransactionManager);
}

@Test //note that there is no @Transactional configured for the method
public void test() throws InterruptedException {

    final Contract c1 = transactionTemplate.execute(new TransactionCallback<Contract>() {
        @Override
        public Contract doInTransaction(TransactionStatus status) {
            Contract c = contractDOD.getNewTransientContract(15);
            contractRepository.save(c);
            return c;
        }
    });

    ExecutorService executorService = Executors.newFixedThreadPool(5);

    for (int i = 0; i < 5; ++i) {
        executorService.execute(new Runnable() {
            @Override  //note that there is no @Transactional configured for the method
            public void run() {
                transactionTemplate.execute(new TransactionCallback<Object>() {
                    @Override
                    public Object doInTransaction(TransactionStatus status) {

                        return null;
                    }
                });

System.Net.HttpWebRequest adds the header 'HTTP header "Expect: 100-Continue"' to every request unless you explicitly ask it not to by setting this static property to false:

System.Net.ServicePointManager.Expect100Continue = false;

Some servers choke on that header and send back the 417 error you're seeing.

Give that a shot.

public static List<T> ListCompare<T>(List<T> List1 , List<T> List2 , string key )
{
    return List1.Select(t => t.GetType().GetProperty(key).GetValue(t))
                .Intersect(List2.Select(t => t.GetType().GetProperty(key).GetValue(t))).ToList();
}

First, I'd make sure that this really is a performance bottleneck, otherwise I'd go with the solution that is cleanest and most expressive.

If it IS a performance bottleneck, just try the different strategies and see what's the quickest. My bet is on creating a new ArrayList and puting the desired objects in that one, discarding the old ArrayList.

It means "not equal to" (as in, the values in cells E37-N37 are not equal to "", or in other words, they are not empty.)

My understanding is that "-u" or "--set-upstream" allows you to specify the upstream (remote) repository for the branch you're on, so that next time you run "git push", you don't even have to specify the remote repository.

Push and set upstream (remote) repository as origin:

$ git push -u origin

Next time you push, you don't have to specify the remote repository:

$ git push

I found App called Iconizer. You can find repository on github. Iconizer can generate app icons for OS X, iPad, iPhone, CarPlay and Apple Watch with just one image.

Simply Drag and Drop your icon onto Iconizer, select the platforms you need and whether or not you want all platforms generated into one asset catalog, then hit export.

After that just replace (delete and import) your AppIcon in the Assets.xcassets

For me the best is Motodev is a Eclipse plugin developed by Motorola.

You can usually just re-evaluate the changed region. Mark the region of ~/.emacs that you've changed, and then use M-x eval-region RET. This is often safer than re-evaluating the entire file since it's easy to write a .emacs file that doesn't work quite right after being loaded twice.

As of iOS 5 this one is far more easy:

[newView setAlpha:0.0];
[UIView animateWithDuration:0.4 animations:^{
    [newView setAlpha:0.5];
}];

If you're in a .tsx file you cannot just write <T>, but this works:

const foo = <T, >(x: T) => x;

As opposed to the extends {} hack, this hack at least preserves the intent.

Based on your application type/size/load/no. of users ..etc - u can keep following as your production properties

spring.datasource.tomcat.initial-size=50
spring.datasource.tomcat.max-wait=20000
spring.datasource.tomcat.max-active=300
spring.datasource.tomcat.max-idle=150
spring.datasource.tomcat.min-idle=8
spring.datasource.tomcat.default-auto-commit=true

As an addition

basically the number of columns have to be equal to the number of columns in the GROUP BY clause

is not a correct statement.

• Any attribute which is not a part of GROUP BY clause can not be used for selection
• Any attribute which is a part of GROUP BY clause can be used for selection but not mandatory.

Try to set ENV PATH. Add PHP path in to ENV PATH.

In order for this extension to work, there are DLL files that must be available to the Windows system PATH. For information on how to do this, see the FAQ entitled "How do I add my PHP directory to the PATH on Windows". Although copying DLL files from the PHP folder into the Windows system directory also works (because the system directory is by default in the system's PATH), this is not recommended. This extension requires the following files to be in the PATH: libeay32.dll

I found 3 occasions where I needed to do this:

• allocating/deallocating objects in memory created by memory-mapped-io or shared memory
• when implementing a given C interface using C++ (yes this still happens today unfortunately (because I don't have enough clout to change it))
• when implementing allocator classes

For me placing my fonts folder as per location specified in bootstrap.css solved the problem

Mostly its fonts folder should be in parent directory of bootstrap.css file .

I faced this problem , and researching many answers , if anyone still in 2015 faces this problem then its either a CSS problem , or location mismatch for files .

The bug has already been solved by bootstrap

You need to add the jar file in the classpath. To compile your java class:

javac -cp .;jwitter.jar MyClass.java

To run your code (provided that MyClass contains a main method):

java -cp .;jwitter.jar MyClass

You can have the jar file anywhere. The above work if the jar file is in the same directory as your java file.

You need to access a geocoding service (i.e. from Google), there is no simple formula to transfer addresses to geo coordinates.

You have to add the following dependency to your build:

<dependency>
    <groupId>org.openrdf.sesame</groupId>
    <artifactId>sesame-rio-api</artifactId>
    <version>2.7.2</version>
</dependency>

Furthermore i would suggest to take a deep look into the documentation about how to use the lib.

I had the same problem, but i could not use the background option (and didn't want to use multiple backgrounds) so i thought of another solution

this is an example for a menu that has a square like indicator for the active/current menu item (the default list style is set to none in another rule)

nav ul li.active>a:before{
    content: "¦";
    position: absolute;
    top: -22px;
    left: 55px;
    font-size: 33px;

}

it creates a square by using a square character with the ":before" pseudo class and it is freely positionable by using absolute positioning.

For me worked when I changed "directory" content into this:

<Directory  "*YourLocation*">
Options All
AllowOverride All
Require all granted  
</Directory>

Perhaps not the most efficient solution, but certainly short & simple:

def repstr(string, length):
    return (string * length)[0:length]

repstr("foobar", 14)

Gives "foobarfoobarfo". One thing about this version is that if length < len(string) then the output string will be truncated. For example:

repstr("foobar", 3)

Gives "foo".

Edit: actually to my surprise, this is faster than the currently accepted solution (the 'repeat_to_length' function), at least on short strings:

from timeit import Timer
t1 = Timer("repstr('foofoo', 30)", 'from __main__ import repstr')
t2 = Timer("repeat_to_length('foofoo', 30)", 'from __main__ import repeat_to_length')
t1.timeit()  # gives ~0.35 secs
t2.timeit()  # gives ~0.43 secs

Presumably if the string was long, or length was very high (that is, if the wastefulness of the string * length part was high) then it would perform poorly. And in fact we can modify the above to verify this:

from timeit import Timer
t1 = Timer("repstr('foofoo' * 10, 3000)", 'from __main__ import repstr')
t2 = Timer("repeat_to_length('foofoo' * 10, 3000)", 'from __main__ import repeat_to_length')
t1.timeit()  # gives ~18.85 secs
t2.timeit()  # gives ~1.13 secs

"find '-maxdepth' " does not work with my old version of bash, therefore I use:

for f in $(ls) ; do if [ -f $f ] ; then echo $f ; fi ; done

Recommendations for how to catch which part of your CSS is causing the issue:

1) set style="height:auto;" on all the <div> elements and retry again.

2) Set style="border: 3px solid red;" on all the <div> elements to see how wide of an area your <div>'s box is taking up.

3) Take away all the css height:#px; properties from your CSS and start over.

So for example:

<div id="I" style="height:auto;border: 3px solid red;">I
    <div id="A" style="height:auto;border: 3px solid purple;">A
        <div id="1A" style="height:auto;border: 3px solid green;">1A
        </div>
        <div id="2A" style="height:auto;border: 3px solid green;">2A
        </div>
    </div>
    <div id="B" style="height:auto;border: 3px solid purple;">B
        <div id="1B" style="height:auto;border: 3px solid green;">1B
        </div>
        <div id="2B" style="height:auto;border: 3px solid green;">2B
        </div>
    </div>
</div>

If you set { responseType: 'blob' }, no need to create Blob on your own. You can simply create url based with response content:

$http({
    url: "...",
    method: "POST",
    responseType: "blob"
}).then(function(response) {
    var fileURL = URL.createObjectURL(response.data);
    window.open(fileURL);
});

What is the "Visual C#"? There is no such thing. Just C#, or .NET C# :)

Also, Python's convention for constants CONSTANT_NAME is not very common in C#. We are usually using CamelCase according to MSDN standards, e.g. public const string ExtractedMagicString = "vs2019";

With MongoDB version 4.2+, updates are more flexible as it allows the use of aggregation pipeline in its update, updateOne and updateMany. You can now transform your documents using the aggregation operators then update without the need to explicity state the $set command (instead we use $replaceRoot: {newRoot: "$$ROOT"})

Here we use the aggregate query to extract the timestamp from MongoDB's ObjectID "_id" field and update the documents (I am not an expert in SQL but I think SQL does not provide any auto generated ObjectID that has timestamp to it, you would have to automatically create that date)

var collection = "person"

agg_query = [
    {
        "$addFields" : {
            "_last_updated" : {
                "$toDate" : "$_id"
            }
        }
    },
    {
        $replaceRoot: {
            newRoot: "$$ROOT"
        } 
    }
]

db.getCollection(collection).updateMany({}, agg_query, {upsert: true})

1. I highly recommend bootstrap-rtl. It is built over Bootstrap core, and rtl support is added as it is a bootstrap theme. This would make your code more maintainable as you can always update your core bootstrap files. CDN

2. Another option to use this stand-alone library, It also comes with few awesome Arabic fonts.

I found that inserting \\n works. I.e., you escape the escaped new line character

def copy_myfile_dirOne_to_dirSec(src, dest, ext): 

    if not os.path.exists(dest):    # if dest dir is not there then we create here
        os.makedirs(dest);
        
    for item in os.listdir(src):
        if item.endswith(ext):
            s = os.path.join(src, item);
            fd = open(s, 'r');
            data = fd.read();
            fd.close();
            
            fname = str(item); #just taking file name to make this name file is destination dir     
            
            d = os.path.join(dest, fname);
            fd = open(d, 'w');
            fd.write(data);
            fd.close();
    
    print("Files are copyed successfully")

Pretty simple

public class SomeClass{

    private int number;
    private String someString;

    public SomeClass(){
        number = 0;
        someString = new String();
    }

    public SomeClass(int number){
        this(); //set the class to 0
        this.setNumber(number); 
    }

    public SomeClass(int number, String someString){
        this(number); //call public SomeClass( int number )
        this.setString(someString);
    }

    public void setNumber(int number){
        this.number = number;
    }
    public void setString(String someString){
        this.someString = someString;
    }
    //.... add some accessors
}

now here is some small extra credit:

public SomeOtherClass extends SomeClass {
    public SomeOtherClass(int number, String someString){
         super(number, someString); //calls public SomeClass(int number, String someString)
    }
    //.... Some other code.
}

Hope this helps.

It's not a good idea to use hbm2ddl.auto in production.

The only way to manage the database schema is to use incremental migration scripts because:

• the scripts will reside in VCS along with your codebase. When you check out a branch, you recreate the whole schema from scratch.
• the incremental scripts can be tested on a QA server before being applied in production
• there is no need for manual intervention since the scripts can be run by Flyway, hence it reduces the possibility of human error associated with running scripts manually.

Even the Hibernate User Guide advise you to avoid using the hbm2ddl tool for production environments.

WHERE NOT (someColumn LIKE '%Apples%')

In base R a formula interface with interactions (:) can be used to achieve this.

df <- read.csv("~/Desktop/TestData.csv")
df <- data.frame(stack(df[,-1]), Label=df$Label) # reshape to long format

boxplot(values ~ Label:ind, data=df, col=c("red", "limegreen"), las=2)

I know this is extremely old, but I understand that this error type is a common mistake for beginners to make since most beginners will call their functions upon their header element being loaded. Seeing as this solution is not addressed at all in this thread, I'll add it. It is very likely that this javascript function was placed before the actual html was loaded. Remember, if you immediately call your javascript before the document is ready then elements requiring an element from the document might find an undefined value.

If you get an error like: cannot map zero-fill pages: Cannot allocate memory in Unknown on line 0, it could be because you don't have a swap file. I suggest you take a look at the tutorial mentioned in this answer: https://stackoverflow.com/a/20275282/828366

Laravel 5 uses .env file to configure your app. .env should not be committed on your repository, like github or bitbucket. On your local environment your .env will look like the following:

# .env
APP_ENV=local

For your production server, you might have the following config:

# .env
APP_ENV=production

Additional to the main answer I needed to remove all npm instances found in:

rm -rf /usr/local/share/man/man1/npm*

I know this is quite out of date, but this might still be useful for those coming late to the party. (EDIT: updated since this still gets traffic and @Goozak has pointed out in the comments that my original analysis of the sample was incorrect as well.)

I pulled this from the example code in your link:

IF !%1==! GOTO VIEWDATA
REM  IF NO COMMAND-LINE ARG...
FIND "%1" C:\BOZO\BOOKLIST.TXT
GOTO EXIT0
REM  PRINT LINE WITH STRING MATCH, THEN EXIT.

:VIEWDATA
TYPE C:\BOZO\BOOKLIST.TXT | MORE
REM  SHOW ENTIRE FILE, 1 PAGE AT A TIME.

:EXIT0

!%1==! is simply an idiomatic use of == intended to verify that the thing on the left, that contains your variable, is different from the thing on the right, that does not. The ! in this case is just a character placeholder. It could be anything. If %1 has content, then the equality will be false, if it does not you'll just be comparing ! to ! and it will be true.

!==! is not an operator, so writing "asdf" !==! "fdas" is pretty nonsensical.

The suggestion to use if not "asdf" == "fdas" is definitely the way to go.

To generate jar file in eclipse right click on the project for which you want to generate, Select Export>Java>Runnable Jar File,

I'm using following markup and had encoutered the same problem:

<ul class="nav">
    <li><a href="abc.html">abc</a></li>
    <li><a href="def.html">def</a></li>
</ul>

Here I have used the following logic:

$(".nav > li").click(function(e){
    if(e.target != this) return; // only continue if the target itself has been clicked
    // this section only processes if the .nav > li itself is clicked.
    alert("you clicked .nav > li, but not it's children");
});

In terms of the exact question, I can see that working as follows:

$(".example").click(function(e){
   if(e.target != this) return; // only continue if the target itself has been clicked
   $(".example").fadeOut("fast");
});

or of course the other way around:

$(".example").click(function(e){
   if(e.target == this){ // only if the target itself has been clicked
       $(".example").fadeOut("fast");
   }
});

Hope that helps.

• Elasticsearch will assign the entire heap specified in jvm.options via the Xms (minimum heap size) and Xmx (maximum heap size) settings.

If you're wanting this as a script, the following Bash script should do what you want (plus tell you when the file already exists):

#!/bin/bash
if [ -e $1 ]; then
  echo "File $1 already exists!"
else
  echo >> $1
fi

If you don't want the "already exists" message, you can use:

#!/bin/bash
if [ ! -e $1 ]; then
  echo >> $1
fi

Edit about using:

Save whichever version with a name you like, let's say "create_file" (quotes mine, you don't want them in the file name). Then, to make the file executatble, at a command prompt do:

chmod u+x create_file

Put the file in a directory in your path, then use it with:

create_file NAME_OF_NEW_FILE

The $1 is a special shell variable which takes the first argument on the command line after the program name; i.e. $1 will pick up NAME_OF_NEW_FILE in the above usage example.

The first version is a null object while the second is an Array object with zero elements.

Null may mean here for example that no location is available for that user, no location has been requested or that some restrictions apply. Hard to tell with no reference to the API.

You could try this:

#include <stdio.h>

int main() 
{  
  int i,j;
  int my_array[3][3] ={10, 23, 42, 1, 654, 0, 40652, 22, 0};
  for(i = 0; i < 3; i++) 
  {
       for(j = 0; j < 3; j++) 
       {
         printf("%d ", my_array[i][j]);
       }
    printf("\n");
  } 
  return 0;
}

Based on luttken's answer. Thought I'd add my twist :)

IEnumerable is an interface that defines one method GetEnumerator which returns an IEnumerator interface, this in turn allows readonly access to a collection. A collection that implements IEnumerable can be used with a foreach statement.

This is a little hacky I guess, but it results in the correct validation attributes etc being applied

@Html.Raw(Html.TextBoxFor(m => m.File).ToHtmlString().Replace("type=\"text\"", "type=\"file\""))

Peg the pattern to find "\\.dbf" at the end of the string using the $ character:

list.files(pattern = "\\.dbf$")

As others have mentioned, try stopPropagation().

And there is a second handler to try: event.cancelBubble = true; It's a IE specific handler, but it is supported in at least FF. Don't really know much about it, as I haven't used it myself, but it might be worth a shot, if all else fails.

In C++ you would use std::find, and check if the resultant pointer points to the end of the range, like this:

Foo array[10];
... // Init the array here
Foo *foo = std::find(std::begin(array), std::end(array), someObject);
// When the element is not found, std::find returns the end of the range
if (foo != std::end(array)) {
    cerr << "Found at position " << std::distance(array, foo) << endl;
} else {
    cerr << "Not found" << endl;
}

TextView comes with 4 compound drawables, one for each of left, top, right and bottom.

In your case, you do not need the LinearLayout and ImageView at all. Just add android:drawableLeft="@drawable/up_count_big" to your TextView.

See TextView#setCompoundDrawablesWithIntrinsicBounds for more info.

This answer is more like an addition and a slight modification to the answers above.

In some versions of Visual Studio (and possibly other compilers) there is a bug that is really annoying and doesn't make sense. So if you declare/define your swap function like this:

friend void swap(A& first, A& second) {

    std::swap(first.size, second.size);
    std::swap(first.arr, second.arr);

}

... the compiler will yell at you when you call the swap function:

This has something to do with a friend function being called and this object being passed as a parameter.

A way around this is to not use friend keyword and redefine the swap function:

void swap(A& other) {

    std::swap(size, other.size);
    std::swap(arr, other.arr);

}

This time, you can just call swap and pass in other, thus making the compiler happy:

After all, you don't need to use a friend function to swap 2 objects. It makes just as much sense to make swap a member function that has one other object as a parameter.

You already have access to this object, so passing it in as a parameter is technically redundant.

Based on this answer, I tried following (with https url):

1. initial cloning of repo:

git clone --depth 25 url-here

2. fetch commits with increasing twice per try depth:

git fetch --depth 50

git fetch --depth 100

git fetch --depth 200

...and so on

3. eventually (when I think enough is fetched) I run git fetch --unshallow - and it's done.

The process obviously takes much more time, but in my case setting http.postBuffer and core.compression didn't help.

UPD: I found out that fetching via ssh works for any repo size (discovered accidentally), done with git clone <ssh url>, given you have created ssh keys. Once repo is fetched, I change remote address using git remote set-url <https url to repo>

If you want to do it by ClassName you could do:

<script type="text/javascript">
function hideTd(className){
    var elements;

    if (document.getElementsByClassName)
    {
        elements = document.getElementsByClassName(className);
    }
    else
    {
        var elArray = [];
        var tmp = document.getElementsByTagName(elements);  
        var regex = new RegExp("(^|\\s)" + className+ "(\\s|$)");
        for ( var i = 0; i < tmp.length; i++ ) {

            if ( regex.test(tmp[i].className) ) {
                elArray.push(tmp[i]);
            }
        }

        elements = elArray;
    }

    for(var i = 0, i < elements.length; i++) {
       if( elements[i].textContent == ''){
          elements[i].style.display = 'none';
       } 
    }

I looked into this a lot because I needed to use a numpy.array as a set in one of my school projects and I needed to be initialized empty... I didn't found any relevant answer here on Stack Overflow, so I started doodling something.

# Initialize your variable as an empty list first
In [32]: x=[]
# and now cast it as a numpy ndarray
In [33]: x=np.array(x)

The result will be:

In [34]: x
Out[34]: array([], dtype=float64)

Therefore you can directly initialize an np array as follows:

In [36]: x= np.array([], dtype=np.float64)

I hope this helps.

Here is another possible way:

void main() {
  var s1 = Singleton.instance;
  s1.somedata = 123;
  var s2 = Singleton.instance;
  print(s2.somedata); // 123
  print(identical(s1, s2));  // true
  print(s1 == s2); // true
  //var s3 = new Singleton(); //produces a warning re missing default constructor and breaks on execution
}

class Singleton {
  static final Singleton _singleton = new Singleton._internal();
  Singleton._internal();
  static Singleton get instance => _singleton;
  var somedata;
}

.button{
    background-image:url('/image/btn.png');
    background-repeat:no-repeat;
}

I stumbled across this article looking for a similar answer. I read @vsync example Using javascript's Number.prototype.toLocaleString: and it appeared to work well. The only complaint I had was that if you had more than a single input type="currency" within your page it would only modify the first instance of it.

As he mentions in his comments it was only designed as an example for stackoverflow.

However, the example worked well for me and although I have little experience with JS I figured out how to modify it so that it will work with multiple input type="currency" on the page using the document.querySelectorAll rather than document.querySelector and adding a for loop.

I hope this can be useful for someone else. ( Credit for the bulk of the code is @vsync )

var currencyInput = document.querySelectorAll( 'input[type="currency"]' );

for ( var i = 0; i < currencyInput.length; i++ ) {

    var currency = 'GBP'
    onBlur( {
        target: currencyInput[ i ]
    } )

    currencyInput[ i ].addEventListener( 'focus', onFocus )
    currencyInput[ i ].addEventListener( 'blur', onBlur )

    function localStringToNumber( s ) {
        return Number( String( s ).replace( /[^0-9.-]+/g, "" ) )
    }

    function onFocus( e ) {
        var value = e.target.value;
        e.target.value = value ? localStringToNumber( value ) : ''
    }

    function onBlur( e ) {
        var value = e.target.value

        var options = {
            maximumFractionDigits: 2,
            currency: currency,
            style: "currency",
            currencyDisplay: "symbol"
        }

        e.target.value = ( value || value === 0 ) ?
            localStringToNumber( value ).toLocaleString( undefined, options ) :
            ''
    }
}

    var currencyInput = document.querySelectorAll( 'input[type="currency"]' );

    for ( var i = 0; i < currencyInput.length; i++ ) {

        var currency = 'GBP'
        onBlur( {
            target: currencyInput[ i ]
        } )

        currencyInput[ i ].addEventListener( 'focus', onFocus )
        currencyInput[ i ].addEventListener( 'blur', onBlur )

        function localStringToNumber( s ) {
            return Number( String( s ).replace( /[^0-9.-]+/g, "" ) )
        }

        function onFocus( e ) {
            var value = e.target.value;
            e.target.value = value ? localStringToNumber( value ) : ''
        }

        function onBlur( e ) {
            var value = e.target.value

            var options = {
                maximumFractionDigits: 2,
                currency: currency,
                style: "currency",
                currencyDisplay: "symbol"
            }

            e.target.value = ( value || value === 0 ) ?
                localStringToNumber( value ).toLocaleString( undefined, options ) :
                ''
        }
    }

It's actually not really clearly stated in the standard (RFC 3986) whether a percent-encoded version of . or .. is supposed to have the same this-folder/up-a-folder meaning as the unescaped version. Section 3.3 only talks about “The path segments . and ..”, without clarifying whether they match . and .. before or after pct-encoding.

Personally I find Firefox's interpretation that %2E does not mean . most practical, but unfortunately all the other browsers disagree. This would mean that you can't have a path component containing only . or ...

I think the only possible suggestion is “don't do that”! There are other path components that are troublesome too, typically due to server limitations: %2F, %00 and %5C sequences in paths may also be blocked by some web servers, and the empty path segment can also cause problems. So in general it's not possible to fit all possible byte sequences into a path component.

Compare two MySQL databases

I modified it so you can use ddbb in diferent hosts.

#!/bin/sh

echo "Usage: dbdiff [user1:pass1@dbname1:host] [user2:pass2@dbname2:host] [ignore_table1:ignore_table2...]"

dump () {
  up=${1%%@*}; down=${1##*@}; user=${up%%:*}; pass=${up##*:}; dbname=${down%%:*}; host=${down##*:};
  mysqldump --opt --compact --skip-extended-insert -u $user -p$pass $dbname -h $host $table > $2
}

rm -f /tmp/db.diff

# Compare
up=${1%%@*}; down=${1##*@}; user=${up%%:*}; pass=${up##*:}; dbname=${down%%:*}; host=${down##*:};
for table in `mysql -u $user -p$pass $dbname -h $host -N -e "show tables" --batch`; do
  if [ "`echo $3 | grep $table`" = "" ]; then
    echo "Comparing '$table'..."
    dump $1 /tmp/file1.sql
    dump $2 /tmp/file2.sql
    diff -up /tmp/file1.sql /tmp/file2.sql >> /tmp/db.diff
  else
    echo "Ignored '$table'..."
  fi
done
less /tmp/db.diff
rm -f /tmp/file1.sql /tmp/file2.sql

It looks like the string contains an array with a single MyStok object in it. If you remove square brackets from both ends of the input, you should be able to deserialize the data as a single object:

MyStok myobj = JSON.Deserialize<MyStok>(sc.Substring(1, sc.Length-2));

You could also deserialize the array into a list of MyStok objects, and take the object at index zero.

var myobjList = JSON.Deserialize<List<MyStok>>(sc);
var myObj = myobjList[0];

PageMethod an easier and faster approach for Asp.Net AJAX We can easily improve user experience and performance of web applications by unleashing the power of AJAX. One of the best things which I like in AJAX is PageMethod.

PageMethod is a way through which we can expose server side page's method in java script. This brings so many opportunities we can perform lots of operations without using slow and annoying post backs.

In this post I am showing the basic use of ScriptManager and PageMethod. In this example I am creating a User Registration form, in which user can register against his email address and password. Here is the markup of the page which I am going to develop:

<body>
    <form id="form1" runat="server">
    <div>
        <fieldset style="width: 200px;">
            <asp:Label ID="lblEmailAddress" runat="server" Text="Email Address"></asp:Label>
            <asp:TextBox ID="txtEmail" runat="server"></asp:TextBox>
            <asp:Label ID="lblPassword" runat="server" Text="Password"></asp:Label>
            <asp:TextBox ID="txtPassword" runat="server"></asp:TextBox>
        </fieldset>
        <div>
        </div>
        <asp:Button ID="btnCreateAccount" runat="server" Text="Signup"  />
    </div>
    </form>
</body>
</html>

To setup page method, first you have to drag a script manager on your page.

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">
</asp:ScriptManager>

Also notice that I have changed EnablePageMethods="true".
This will tell ScriptManager that I am going to call PageMethods from client side.

Now next step is to create a Server Side function.
Here is the function which I created, this function validates user's input:

[WebMethod]
public static string RegisterUser(string email, string password)
{
    string result = "Congratulations!!! your account has been created.";
    if (email.Length == 0)//Zero length check
    {
        result = "Email Address cannot be blank";
    }
    else if (!email.Contains(".") || !email.Contains("@")) //some other basic checks
    {
        result = "Not a valid email address";
    }
    else if (!email.Contains(".") || !email.Contains("@")) //some other basic checks
    {
        result = "Not a valid email address";
    }

    else if (password.Length == 0)
    {
        result = "Password cannot be blank";
    }
    else if (password.Length < 5)
    {
        result = "Password cannot be less than 5 chars";
    }

    return result;
}

To tell script manager that this method is accessible through javascript we need to ensure two things:
First: This method should be 'public static'.
Second: There should be a [WebMethod] tag above method as written in above code.

Now I have created server side function which creates account. Now we have to call it from client side. Here is how we can call that function from client side:

<script type="text/javascript">
    function Signup() {
        var email = document.getElementById('<%=txtEmail.ClientID %>').value;
        var password = document.getElementById('<%=txtPassword.ClientID %>').value;

        PageMethods.RegisterUser(email, password, onSucess, onError);

        function onSucess(result) {
            alert(result);
        }

        function onError(result) {
            alert('Cannot process your request at the moment, please try later.');
        }
    }
</script>

To call my server side method Register user, ScriptManager generates a proxy function which is available in PageMethods.
My server side function has two paramaters i.e. email and password, after that parameters we have to give two more function names which will be run if method is successfully executed (first parameter i.e. onSucess) or method is failed (second parameter i.e. result).

Now every thing seems ready, and now I have added OnClientClick="Signup();return false;" on my Signup button. So here complete code of my aspx page :

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">
        </asp:ScriptManager>
        <fieldset style="width: 200px;">
            <asp:Label ID="lblEmailAddress" runat="server" Text="Email Address"></asp:Label>
            <asp:TextBox ID="txtEmail" runat="server"></asp:TextBox>
            <asp:Label ID="lblPassword" runat="server" Text="Password"></asp:Label>
            <asp:TextBox ID="txtPassword" runat="server"></asp:TextBox>
        </fieldset>
        <div>
        </div>
        <asp:Button ID="btnCreateAccount" runat="server" Text="Signup" OnClientClick="Signup();return false;" />
    </div>
    </form>
</body>
</html>

<script type="text/javascript">
    function Signup() {
        var email = document.getElementById('<%=txtEmail.ClientID %>').value;
        var password = document.getElementById('<%=txtPassword.ClientID %>').value;

        PageMethods.RegisterUser(email, password, onSucess, onError);

        function onSucess(result) {
            alert(result);
        }

        function onError(result) {
            alert('Cannot process your request at the moment, please try later.');
        }
    }
</script>

You can use view.setZ(float) starting from API level 21. Here you can find more info.

I think you should add further control to this:

    var disableRes = false;
    var refreshWindow = function() {
        disableRes = false;
        location.reload();
    }
    var resizeTimer;
    if (disableRes == false) {
        jQuery(window).resize(function() {
            disableRes = true;
            clearTimeout(resizeTimer);
            resizeTimer = setTimeout(refreshWindow, 1000);
        });
    }

As @Sourabh already pointed out, you can check in the Google Maven link what are the packages that Google has listed out.

If you, like me, are prompted with a similar message to this Failed to resolve: com.android.support:appcompat-v7:28.0, it could be that you got there after upgrading the targetSdkVersion or compileSdkVersion.

What is basically happening is that the package is not being found, as the message correctly says. If you upgraded the SDK, check the Google Maven, to check what are the available versions of the package for the new SDK version that you want to upgrade to.

I had these dependencies (on version 27):

implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support:recyclerview-v7:27.1.1'
implementation 'com.android.support:cardview-v7:27.1.1'
implementation 'com.android.support:support-v4:27.1.1'

And I had to change the SDK version and the rest of the package number:

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'
implementation 'com.android.support:cardview-v7:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'

Now the packages are found and downloaded. Since the only available package for the 28 version of the SDK is 28.0.0 at the moment of writing this.

@OP, you were awfully close with your "non-elegant" solution.

How about:

<div class="month" *ngFor="let item of [].constructor(10); let i = index"> ... </div>

Here I'm getting the Array constructor from an empty array: [].constructor, because Array isn't a recognized symbol in the template syntax, and I'm too lazy to do Array=Array or counter = Array in the component typescript like @pardeep-jain did in his 4th example. And I'm calling it without new because new isn't necessary for getting an array out the Array constructor.

Array(30) and new Array(30) are equivalent.

The array will be empty, but that doesn't matter because you really just want to use i from ;let i = index in your loop.

In case you use ASP.NET MVC, generate many checkboxes and later have to select/unselect all using JavaScript you can do the following.

HTML

@foreach (var item in Model)
{
    @Html.CheckBox(string.Format("ProductId_{0}", @item.Id), @item.IsSelected)
}

JavaScript

function SelectAll() {       
        $('input[id^="ProductId_"]').each(function () {          
            $(this).prop('checked', true);
        });
    }

    function UnselectAll() {
        $('input[id^="ProductId_"]').each(function () {
            $(this).prop('checked', false);
        });
    }

For the ones who are getting the error while requesting JSON data:

If your are requesting JSON data, the JSON might be too large and that what cause the error to happen.

My solution is to copy the request link to new tab (get request from browser) copy the data to JSON viewer online where you have auto parsing and work on it there.

Does that work in IE6?

No, IE6 does not support attribute selectors at all, cf. CSS Compatibility and Internet Explorer.

You might find How to workaround: IE6 does not support CSS “attribute” selectors worth the read.

EDIT
If you are to ignore IE6, you could do (CSS2.1):

input[type=submit][disabled=disabled],
button[disabled=disabled] {
    ...
}

CSS3 (IE9+):

input[type=submit]:disabled,
button:disabled {
    ...
}

You can substitute [disabled=disabled] (attribute value) with [disabled] (attribute presence).

Python lists translate to JSON arrays. What it is giving you is a perfectly valid JSON string that could be used in a Javascript application. To get what you expected, you would need to use a dict:

>>> json.dumps({'apple': 'cat', 'banana':'dog', 'pear':'fish'})
'{"pear": "fish", "apple": "cat", "banana": "dog"}'

try this

delimiter ;;

drop procedure if exists test2;;

create procedure test2()

begin

select ‘Hello World’;

end

;;

Your character class (the part in the square brackets) is saying that you want to match anything except 0-9 and a-z and +. You aren't explicit about how many a-z or 0-9 you want to match, but I assume the + means you want to replace strings of at least one alphanumeric character. It should read instead:

str = str.replace(/[^-a-z0-9]+/g, "");

Also, if you need to match upper-case letters along with lower case, you should use:

str = str.replace(/[^-a-zA-Z0-9]+/g, "");

You might also gain a very subsquent performance boost by changing the following Git configuration:

git config --global status.submoduleSummary false

When running the simple git status command on Window 7 x64, it took my computer more than 30 seconds to run. After this option was defined, the command is immediate.

Activating Git's own tracing as explained in the following page helped me found the origin of the problem, which might differ in your installation: https://github.com/msysgit/msysgit/wiki/Diagnosing-why-Git-is-so-slow

In order to scroll down to the bottom of the page first we have to select an id which resides at the bottom of the page. Then we can use the document.getElementById to select the id and scroll down using scrollIntoView(). Please refer the below code.

   scrollToBottom= async ()=>{
      document.getElementById('bottomID').scrollIntoView();
    }

That's 32 hex characters - 1 hex character is 4 bits.

Just don't anchor your pattern:

/Test/

The above regex will check for the literal string "Test" being found somewhere within it.

Log.v("blah", "blah blah");

You need to add the android Log view in eclipse to see them. There are also other methods depending on the severity of the message (error, verbose, warning, etc..).

You can try it with DecimalFormat. With this class you are very flexible in parsing your numbers.
You can exactly set the pattern you want to use.
In your case for example:

double test = 12345678;
DecimalFormat df = new DecimalFormat("#");
df.setMaximumFractionDigits(0);
System.out.println(df.format(test)); //12345678

import sys
for a in sys.path:
    a.replace('\\\\','\\')
    print(a)

It will give all the paths ready for place in the Windows.

Had an issue with the path, it turns out that you need to specify the first '/' to get it to work! I am using VSCode/Python on macOS

You can check this sample code to understand how you can access the relative path using the java sample code

import java.io.File;

public class MainClass {

  public static void main(String[] args) {

    File relative = new File("html/javafaq/index.html");

    System.out.println("relative: ");
    System.out.println(relative.getName());
    System.out.println(relative.getPath());
  }
}

Here getPath will display the relative path of the file.

The git diffs have an extra path segment prepended to the file paths. You can strip the this entry in the path by specifying -p1 with patch, like so:

patch -p1 < save.patch

It's very cool you can capitalize Only the first letter of an input field With this one.. If any one know how to capitalize Like CSS text-transform:capitalize, Please Reply .. Here You go..

$('input-field').keyup(function(event) { $(this).val(($(this).val().substr(0,1).toUpperCase())+($(this).val().substr(1))); });

You need to catch the return value.

The DateTime.AddDays method returns an object who's value is the sum of the date and time of the instance and the added value.

endDate = endDate.AddDays(addedDays);

This works for me. I'm using Identity 2.0, it looks like GetApplicationUser isn't there anymore.

        var user = await UserManager.FindByIdAsync(User.Identity.GetUserId());
        if (!string.IsNullOrEmpty(form["FirstName"]))
        {
            user.FirstName = form["FirstName"];
        }
        if (!string.IsNullOrEmpty(form["LastName"]))
        {
            user.LastName = form["LastName"];
        }
        IdentityResult result = await UserManager.UpdateAsync(user);

You have an image or a favicon link of the style ="../" somewhere, that if the "../" were valid, would go beyond the top of the site, like this:

Image:

http://example.com/Images/test.jpg

Page

http://example.com/Pages/test.aspx

Valid on that page: ../Images/test.jpg
Would throw an error: ../../Images/test.jpg

I had the same issue, following fix solved my problem.

• Select Type as 'TIMESTAMP'

• DON'T ENTER ANYTHING IN LENGTH/VALUES FIELD. KEEP IT BLANK

• Select CURRENT_TIMESTAMP as Default value.

The easiest way is probably to use xvfb-run:

xvfb-run does the whole X authority dance for you, give it a try!

You can use those queries to find all FKs for your table.

Declare @TableName VarChar(200) = 'Table name'

-- Find FK in This table.

I know this answer comes a little late but I recently faced a similar problem. I wanted to trigger an event on a nested component. I had a list with radio and check box type widgets (they were divs that behaved like checkboxes and/or radio buttons) and in some other place in the application, if someone closed a toolbox, I needed to uncheck one.

I found a pretty simple solution, not sure if this is best practice but it works.

var event = new MouseEvent('click', {
 'view': window, 
 'bubbles': true, 
 'cancelable': false
});
var node = document.getElementById('nodeMyComponentsEventIsConnectedTo');
node.dispatchEvent(event);

This triggered the click event on the domNode and my handler attached via react was indeed called so it behaves like I would expect if someone clicked on the element. I have not tested onChange but it should work, and not sure how this will fair in really old versions of IE but I believe the MouseEvent is supported in at least IE9 and up.

I eventually moved away from this for my particular use case because my component was very small (only a part of my application used react since i'm still learning it) and I could achieve the same thing another way without getting references to dom nodes.

UPDATE:

As others have stated in the comments, it is better to use this.refs.refname to get a reference to a dom node. In this case, refname is the ref you attached to your component via <MyComponent ref='refname' />.

It tells the interpreter which version of python to run the program with when you have multiple versions of python.

You can find the solution in Problems passing system properties and parameters when running Java class via Gradle . Both involve the use of the args property

Also you should read the difference between passing with -D or with -P that is explained in the Gradle documentation

Cardinality of a set is the namber of the elements in set for we have a set a > a,b,c < so ths set contain 3 elements 3 is the cardinality of that set

A simple drop-in solution for replacing a forEach() await loop that is not working is replacing forEach with map and adding Promise.all( to the beginning.

For example:

await y.forEach(async (x) => {

to

await Promise.all(y.map(async (x) => {

An extra ) is needed at the end.

Here is a simple routine for an array of primitive elements:

for ($i = 0; $i < count($mySimpleArray); $i++)
{
   echo $mySimpleArray[$i] . "\n";
}

Simply install Microsot.ReportViewer.2012.Runtime nuget package as shown in this answer https://stackoverflow.com/a/33014040/2198830

Your issue is with attempting to change your month by adding 1. 1 in date serials in Excel is equal to 1 day. Try changing your month by using the following:

NewDate = Format(DateAdd("m",1,StartDate),"dd/mm/yyyy")

You can make sure that the object in question is stringified before passing it to parse function by simply using JSON.stringify() .

Updated your line below,

JSON.parse(JSON.stringify({"balance":0,"count":0,"time":1323973673061,"firstname":"howard","userId":5383,"localid":1,"freeExpiration":0,"status":false}));

or if you have JSON stored in some variable:

JSON.parse(JSON.stringify(yourJSONobject));

This worked for me,

CREATE TABLE newtable LIKE oldtable;

Replicates newtable with old table

INSERT newtable SELECT * FROM oldtable;

Copies all the row data to new table.

Thank you
