Update:

Django 2.2 version now has a bulk_update.

Old answer:

Refer to the following django documentation section

Updating multiple objects at once

In short you should be able to use:

ModelClass.objects.filter(name='bar').update(name="foo")

You can also use F objects to do things like incrementing rows:

from django.db.models import F
Entry.objects.all().update(n_pingbacks=F('n_pingbacks') + 1)

See the documentation.

However, note that:

• This won't use ModelClass.save method (so if you have some logic inside it won't be triggered).
• No django signals will be emitted.
• You can't perform an .update() on a sliced QuerySet, it must be on an original QuerySet so you'll need to lean on the .filter() and .exclude() methods.

I think to have the real next or previous row in SQL table we need the real value with equal, (< or >) return more than one if you need to change position of row in a ordering table.

we need the value $position to search the neighbours row In my table I created a column 'position'

and SQL query for getting the needed row is :

for next :

SELECT * 
FROM `my_table` 
WHERE id = (SELECT (id) 
            FROM my_table 
            WHERE position = ($position+1)) 
LIMIT 1

for previous:

 SELECT * 
 FROM my_table 
 WHERE id = (SELECT (id) 
             FROM my_table 
             WHERE `position` = ($position-1)) 
 LIMIT 1

You can fake it like this:

-- with column headings 
select column1, column2 from some_table;

-- without column headings
select column1 as '', column2 as '' from some_table;

I've noticed a couple of minor flaws in grim's jsfiddle.

To get the pointer to change to a hand for the whole of the panel use:

.panel-heading {
   cursor: pointer;
}

I've removed the <a> tag (a style issue) and kept data-toggle="collapse" data-parent="#accordion" data-target="#collapse..." on panel-heading throughout.

I've added a CSS method for displaying chevron, using font-awesome.css in my jsfiddle:

http://jsfiddle.net/weaversnap/7FqsX/1/

For finding the even number we should use

select num from table where ( num % 2 ) = 0

I strongly recommend that you not define your own scheme. This goes against the web standards for URI schemes, which attempts to rigidly control those names for good reason -- to avoid name conflicts between different entities. Once you put a link to your scheme on a web site, you have put that little name into entire the entire Internet's namespace, and should be following those standards.

If you just want to be able to have a link to your own app, I recommend you follow the approach I described here:

How to register some URL namespace (myapp://app.start/) for accessing your program by calling a URL in browser in Android OS?

I had a similar situation, where my master branch and the develop branch I was trying to merge had different commit histories. None of the above solutions worked for me. What did the trick was:

Starting from master:

git branch new_branch
git checkout new_branch
git merge develop --allow-unrelated-histories

Now in the new_branch, there are all the things from develop and I can easily merge into master, or create a pull request, as they now share the same commit hisotry.

You may find that gnuplot's for loops are useful in this case, if you adjust your filenames or graph titles appropriately.

e.g.

filenames = "first second third fourth fifth"
plot for [file in filenames] file."dat" using 1:2 with lines

and

filename(n) = sprintf("file_%d", n)
plot for [i=1:10] filename(i) using 1:2 with lines

This question seems to be answered, however for completeness, I would add another approach.

You can use a unique ID number generator which is based on Twitter's Snowflake id generator. C# implementation can be found here.

var id64Generator = new Id64Generator();

// ...

public string generateID(string sourceUrl)
{
    return string.Format("{0}_{1}", sourceUrl, id64Generator.GenerateId());
}

Note that one of very nice features of that approach is possibility to have multiple generators on independent nodes (probably something useful for a search engine) generating real time, globally unique identifiers.

// node 0
var id64Generator = new Id64Generator(0);

// node 1
var id64Generator = new Id64Generator(1);

// ... node 10
var id64Generator = new Id64Generator(10);

Another option in SQL Server is to do all of your dynamic querying into table variable in a stored proc, then use a cursor to query and process that. As to the dreaded cursor debate :), I have seen studies that show that in some situations, a cursor can actually be faster if properly set up. I use them myself when the required query is too complex, or just not humanly (for me ;) ) possible.

You are missing setter for salt property as indicated by the exception

Please add the setter as

 public void setSalt(long salt) {
      this.salt=salt;
 }

write command in terminal:

vi ~/.vimrc

for set the number:
write set number

for remove number:
write set nonumber

this is because str is pointing to a string literal means a constant string ...but you are trying to modify it by copying . Note : if it would have been an error due to memory allocation it would have been given segmentation fault at the run time .But this error is coming due to constant string modification or you can go through the below for more details abt bus error :

Bus errors are rare nowadays on x86 and occur when your processor cannot even attempt the memory access requested, typically:

• using a processor instruction with an address that does not satisfy its alignment requirements.

Segmentation faults occur when accessing memory which does not belong to your process, they are very common and are typically the result of:

• using a pointer to something that was deallocated.
• using an uninitialized hence bogus pointer.
• using a null pointer.
• overflowing a buffer.

To be more precise this is not manipulating the pointer itself that will cause issues, it's accessing the memory it points to (dereferencing).

...How can I step through my javascript code line by line using Google Chromes developer tools without it going into javascript libraries?...

For the record: At this time (Feb/2015) both Google Chrome and Firefox have exactly what you (and I) need to avoid going inside libraries and scripts, and go beyond the code that we are interested, It's called Black Boxing:

When you blackbox a source file, the debugger will not jump into that file when stepping through code you're debugging.

More info:

• Chrome: Blackbox JavaScript Source Files
• Firefox: Black box libraries in the Debugger

The backslash \ is the escape character for regular expressions. Therefore a double backslash would indeed mean a single, literal backslash.

\ (backslash) followed by any of [\^$.|?*+(){} escapes the special character to suppress its special meaning.

ref : http://www.regular-expressions.info/reference.html

Wrap them around a div with the following CSS

.div_wrapper{
    white-space: nowrap;
}

I always use the below function:

public static String prettyPrintXml(String xmlStringToBeFormatted) {
    String formattedXmlString = null;
    try {
        DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
        documentBuilderFactory.setValidating(true);
        DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
        InputSource inputSource = new InputSource(new StringReader(xmlStringToBeFormatted));
        Document document = documentBuilder.parse(inputSource);

        Transformer transformer = TransformerFactory.newInstance().newTransformer();
        transformer.setOutputProperty(OutputKeys.INDENT, "yes");
        transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");

        StreamResult streamResult = new StreamResult(new StringWriter());
        DOMSource dOMSource = new DOMSource(document);
        transformer.transform(dOMSource, streamResult);
        formattedXmlString = streamResult.getWriter().toString().trim();
    } catch (Exception ex) {
        StringWriter sw = new StringWriter();
        ex.printStackTrace(new PrintWriter(sw));
        System.err.println(sw.toString());
    }
    return formattedXmlString;
}

I've had a very similar issue using spring-boot-starter-data-redis. To my implementation there was offered a @Bean for RedisTemplate as follows:

@Bean
public RedisTemplate<String, List<RoutePlantCache>> redisTemplate(RedisConnectionFactory connectionFactory) {
    final RedisTemplate<String, List<RoutePlantCache>> template = new RedisTemplate<>();
    template.setConnectionFactory(connectionFactory);
    template.setKeySerializer(new StringRedisSerializer());
    template.setValueSerializer(new Jackson2JsonRedisSerializer<>(RoutePlantCache.class));

    // Add some specific configuration here. Key serializers, etc.
    return template;
}

The fix was to specify an array of RoutePlantCache as following:

template.setValueSerializer(new Jackson2JsonRedisSerializer<>(RoutePlantCache[].class));

Below the exception I had:

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `[...].RoutePlantCache` out of START_ARRAY token

Though its really long back this question was posted, I wish to answer as it might help others. This can be done easily by means of JOINKEYS in a SINGLE step. Here goes the pseudo code:

• Code JOINKEYS PAIRED(implicit) and get both the records via reformatting filed. If there is NO match from either of files then append/prefix some special character say '$'
• Compare via IFTHEN for '$', if exists then it doesnt have a paired record, it'll be written into unpaired file and rest to paired file.

Please do get back incase of any questions.

That's probably a requireJS module definition

Check here for more details

RequireJS is a JavaScript file and module loader. It is optimized for in-browser use, but it can be used in other JavaScript environments, like Rhino and Node. Using a modular script loader like RequireJS will improve the speed and quality of your code.

I have been having the same issue and tried everything written here but it was still giving me the same error. Turned out to be NULL value in the column which I was trying to convert.

Removing the NULL value solved my issue.

Cheers, Ahmed

My issue was as simple as having a null reference that didn't show up in the returned message, I had to debug my API to see it.

Collation defines how you sort and compare string values

For example, it defines how to deal with

• accents (äàa etc)
• case (Aa)
• the language context:
  • In a French collation, cote < côte < coté < côté.
  • In the SQL Server Latin1 default , cote < coté < côte < côté
• ASCII sorts (a binary collation)

Browsers make their best guess with the data they receive. This works for markup (which Websites often get wrong) and other media content. A program that receives a file can often figure out what its received regardless of the MIME content type it's been told.

This isn't something you should rely on however. It's recommended you always use the correct MIME content.

Add /Q for quiet mode and it should remove the prompt.

Instead of an annoying confirmation popup, it would be nice to delay leaving just a bit (matter of milliseconds) to manage successfully posting the unsaved data to the server, which I managed for my site using writing dummy text to the console like this:

window.onbeforeunload=function(e){
  // only take action (iterate) if my SCHEDULED_REQUEST object contains data        
  for (var key in SCHEDULED_REQUEST){   
    postRequest(SCHEDULED_REQUEST); // post and empty SCHEDULED_REQUEST object
    for (var i=0;i<1000;i++){
      // do something unnoticable but time consuming like writing a lot to console
      console.log('buying some time to finish saving data'); 
    };
    break;
  };
}; // no return string --> user will leave as normal but data is send to server

Have you tried adding the php_value error_log '/path/to/php_error_log to your VirtualHost configuration?

Create a (local) repository and use yum to have it resolve the dependencies for you.

The CentOS wiki has a nice page providing a how-to on this. CentOS wiki HowTos/CreateLocalRepos.

Summarized and further minimized (not ideal, but quickest):

1. Create a directory for you local repository, e.g. /home/user/repo.
2. Move the RPMs into that directory.

3. Fix some ownership and filesystem permissions:

   # chown -R root.root /home/user/repo
   

4. Install the createrepo package if not installed yet, and run

   # createrepo /home/user/repo
   # chmod -R o-w+r /home/user/repo
   

5. Create a repository configuration file, e.g. /etc/yum.repos.d/myrepo.repo containing

   [local]
   name=My Awesome Repo
   baseurl=file:///home/user/repo
   enabled=1
   gpgcheck=0
   

6. Install your package using

   # yum install packagename
   

The "Pythonic" way to check if a string is empty is:

import random
variable = random.choice(l)
if variable:
    # got a non-empty string
else:
    # got an empty string

Check this one (Password should be password):

<wsse:UsernameToken xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="SecurityToken-6138db82-5a4c-4bf7-915f-af7a10d9ae96">
  <wsse:Username>user</wsse:Username>
  <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">CBb7a2itQDgxVkqYnFtggUxtuqk=</wsse:Password>
  <wsse:Nonce>5ABcqPZWb6ImI2E6tob8MQ==</wsse:Nonce>
  <wsu:Created>2010-06-08T07:26:50Z</wsu:Created>
</wsse:UsernameToken>

I also prefer an enum approach, but I would use a abstract base class to force the subclasses to implement the getType() method.

public abstract class Base
{
  protected enum TYPE
  {
    DERIVED_A, DERIVED_B
  }

  public abstract TYPE getType();

  class DerivedA extends Base
  {
    @Override
    public TYPE getType()
    {
      return TYPE.DERIVED_A;
    }
  }

  class DerivedB extends Base
  {
    @Override
    public TYPE getType()
    {
      return TYPE.DERIVED_B;
    }
  }
}

In my case problem was in JAVA_TOOL_OPTIONS environment variable. Nothing helps me until I removed it. Hope it help someone!

A small combination from a couple of the examples below and created this simple piece:

function ajax(url, method, data, async)
{
    method = typeof method !== 'undefined' ? method : 'GET';
    async = typeof async !== 'undefined' ? async : false;

    if (window.XMLHttpRequest)
    {
        var xhReq = new XMLHttpRequest();
    }
    else
    {
        var xhReq = new ActiveXObject("Microsoft.XMLHTTP");
    }


    if (method == 'POST')
    {
        xhReq.open(method, url, async);
        xhReq.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        xhReq.setRequestHeader("X-Requested-With", "XMLHttpRequest");
        xhReq.send(data);
    }
    else
    {
        if(typeof data !== 'undefined' && data !== null)
        {
            url = url+'?'+data;
        }
        xhReq.open(method, url, async);
        xhReq.setRequestHeader("X-Requested-With", "XMLHttpRequest");
        xhReq.send(null);
    }
    //var serverResponse = xhReq.responseText;
    //alert(serverResponse);
}

// Example usage below (using a string query):

ajax('http://www.google.com');
ajax('http://www.google.com', 'POST', 'q=test');

OR if your parameters are object(s) - minor additional code adjustment:

var parameters = {
    q: 'test'
}

var query = [];
for (var key in parameters)
{
    query.push(encodeURIComponent(key) + '=' + encodeURIComponent(parameters[key]));
}

ajax('http://www.google.com', 'POST', query.join('&'));

Both should be fully browser + version compatible.

you could also store your data in an service with an setter and get it over a getter

import { Injectable } from '@angular/core';

@Injectable()
export class StorageService {

    public scope: Array<any> | boolean = false;

    constructor() {
    }

    public getScope(): Array<any> | boolean {
        return this.scope;
    }

    public setScope(scope: any): void {
        this.scope = scope;
    }
}

Add the below lines in .gitignore and place the file inside ur project folder

/target/
/.classpath
/*.project
/.settings
/*.springBeans

So what is this "require?"

require() is not part of the standard JavaScript API. But in Node.js, it's a built-in function with a special purpose: to load modules.

Modules are a way to split an application into separate files instead of having all of your application in one file. This concept is also present in other languages with minor differences in syntax and behavior, like C's include, Python's import, and so on.

One big difference between Node.js modules and browser JavaScript is how one script's code is accessed from another script's code.

• In browser JavaScript, scripts are added via the <script> element. When they execute, they all have direct access to the global scope, a "shared space" among all scripts. Any script can freely define/modify/remove/call anything on the global scope.

• In Node.js, each module has its own scope. A module cannot directly access things defined in another module unless it chooses to expose them. To expose things from a module, they must be assigned to exports or module.exports. For a module to access another module's exports or module.exports, it must use require().

In your code, var pg = require('pg'); loads the pg module, a PostgreSQL client for Node.js. This allows your code to access functionality of the PostgreSQL client's APIs via the pg variable.

Why does it work in node but not in a webpage?

require(), module.exports and exports are APIs of a module system that is specific to Node.js. Browsers do not implement this module system.

Also, before I got it to work in node, I had to do npm install pg. What's that about?

NPM is a package repository service that hosts published JavaScript modules. npm install is a command that lets you download packages from their repository.

Where did it put it, and how does Javascript find it?

The npm cli puts all the downloaded modules in a node_modules directory where you ran npm install. Node.js has very detailed documentation on how modules find other modules which includes finding a node_modules directory.

Set the tagName as an explicit attribute:

for(var i=0,els=document.querySelectorAll('*'); i<els.length;
          els[i].setAttribute('tagName',els[i++].tagName) );

I needed this myself, for an XML Document, with Nested Tags ending in _Sequence. See JaredMcAteer answer for more details.

document.querySelectorAll('[tagName$="_Sequence"]')

I didn't say it would be pretty :) PS: I would recommend to use tag_name over tagName, so you do not run into interferences when reading 'computer generated', implicit DOM attributes.

From this thread:

 import os
 os.system("import -window root temp.png")

This is the extract of code that I have done.

    String s="08:10:45";
    String[] s1=s.split(":");
    int milipmHrs=0;
    char[] arr=s1[2].toCharArray();
    boolean isFound=s1[2].contains("PM");
    if(isFound){
        int pmHrs=Integer.parseInt(s1[0]);
        milipmHrs=pmHrs+12;
        return(milipmHrs+":"+s1[1]+":"+arr[0]+arr[1]);
    }
    else{

        return(s1[0]+":"+s1[1]+":"+arr[0]+arr[1]);
    }

Find duplicate users by email address with this query...

SELECT users.name, users.uid, users.mail, from_unixtime(created)
FROM users
INNER JOIN (
  SELECT mail
  FROM users
  GROUP BY mail
  HAVING count(mail) > 1
) dupes ON users.mail = dupes.mail
ORDER BY users.mail;

Since Jackson is being used, you have to configure that as a Jackson property. In the case of Spring Boot REST services, you have to configure it in application.properties or application.yml:

spring.jackson.default-property-inclusion = NON_NULL

source

If the code is coming from a file, you can get its full name

sys._getframe().f_code.co_filename

You can also retrieve the function name as f_code.co_name

I had similar problem, I had a list and I have to build a SQL script based on template (that contained @INPUT@ as element to replace):

for i in LIST 
do
    awk "sub(/\@INPUT\@/,\"${i}\");" template.sql >> output
done

This is how you can do it without a Dim, using MessageBox.Show instead of MsgBox. This is in my opinion the cleanest way of writing it!

Select Case MessageBox.Show("Message", "Title", MessageBoxButtons.YesNo)
    Case vbYes
        ' Other Code goes here
    Case vbNo
        ' Other Code goes here
End Select

You can shorten it down even further by using If:

If MessageBox.Show("Message", "Title", MessageBoxButtons.YesNo) = vbYes Then
    ' Other Code goes here
End If

$(document).ready(function() {
 $('#main_search').val('hi');
});

So you want to split on spaces, and on commas and periods that aren't surrounded by numbers. This should work:

r" |(?<![0-9])[.,](?![0-9])"

PHP 7+

As of PHP 7, this task can be performed simply by using the Null coalescing operator like this :

echo !empty($address['street2']) ?? 'Empty';

A global variable has to be initialized to a constant value, like 4 or 0.0 or @"constant string" or nil. A object constructor, such as init, does not return a constant value.

If you want to have a global variable, you should initialize it to nil and then return it using a class method:

NSImage *segment = nil;

+ (NSImage *)imageSegment
{
    if (segment == nil) segment = [[NSImage alloc] initWithContentsOfFile:@"/user/asd.jpg"];
    return segment;
}

But there is switch-case :)

switch (true) {
    case true:
        console.log("Yes, its ture :) Break from the switch-case");
        break;
    case false:
        console.log("Nope, but if the condition was set to false this would be used and then break");
        break;

    default:
        console.log("If all else fails");
        break;
}

Ken has the right solution, but you don't want to add the picturebox.Image.Load() member method.

If you do it with a Load and the ImageLocation is not set, it will fail with a "Image Location must be set" exception. If you use the picturebox.Refresh() member method, it works without the exception.

Completed code below:

public void showAnimatedPictureBox(PictureBox thePicture)
{
            thePicture.Image = Properties.Resources.hamster;
            thePicture.Refresh();
            thePicture.Visible = true;
}

It is invoked as: showAnimatedPictureBox( myPictureBox );

My XAML looks like:

    <Window
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

I realize this is an old post, but loading the image directly from a resource is was extremely unclear on Microsoft's site, and this was the (partial) solution I came to. Hope it helps someone!

If your development environment is Windows make sure the USB drivers are correctly installed.

One way to ensure that the USB drivers are installed correctly is to get the PDANet Windows installer and let it install the USB drivers.

You can find the PDANet page here.

To set permanently,

vim /etc/sysctl.conf

and add

kernel.threads-max = "value"

Just use substring: "apple".substring(3); will return le

You can use:

CREATE LOGIN <login name> WITH PASSWORD = '<password>' ; GO 

To create the login (See here for more details).

Then you may need to use:

CREATE USER user_name 

To create the user associated with the login for the specific database you want to grant them access too.

(See here for details)

You can also use:

GRANT permission  [ ,...n ] ON SCHEMA :: schema_name

To set up the permissions for the schema's that you assigned the users to.

(See here for details)

Two other commands you might find useful are ALTER USER and ALTER LOGIN.

Follow the steps :

1. make sure you have allowed installation from unknown sources in settings.
2. Use the Android Device Monitor to copy the APK to the sdcard.
3. Use the builtin browser in Android to navigate to file:///sdcard/apk-name.apk
4. When the notification "Download complete" appears, click it.

You may have to first update all the records that are null to the default value then use the alter table statement.

Update dbo.TableName
Set
Created="01/01/2000"
where Created is NULL

Here is a simple iterative approach:

public static Node reverse(Node root) {
    if (root == null || root.next == null) {
        return root;
    }

    Node curr, prev, next;
    curr = root; prev = next = null;
    while (curr != null) {
        next = curr.next;
        curr.next = prev;

        prev = curr;
        curr = next;
    }
    return prev;
}

And here is a recursive approach:

public static Node reverseR(Node node) {
    if (node == null || node.next == null) {
        return node;
    }

    Node next = node.next;
    node.next = null;

    Node remaining = reverseR(next);
    next.next = node;
    return remaining;
}

Thanks to @EdChum I was struggling with same problem especially when indexes do not match. Unfortunatly in pandas guide this case is missed (when you for example delete some rows)

import pandas as pd
t=pd.DataFrame()
t['a']=[1,2,3,4]
t=t.loc[t['a']>1] #now index starts from 1

u=pd.DataFrame()
u['b']=[1,2,3] #index starts from 0

#option 1
#keep index of t
u.index = t.index 

#option 2
#index of t starts from 0
t.reset_index(drop=True, inplace=True)

#now concat will keep number of rows 
r=pd.concat([t,u], axis=1)

Scott Murray wrote a great explanation of this^[1]. For instance, for the code snippet:

svg.append("g")
    .attr("class", "axis")
    .attr("transform", "translate(0," + h + ")")
    .call(xAxis);

He explains using the following:

Note that we use attr() to apply transform as an attribute of g. SVG transforms are quite powerful, and can accept several different kinds of transform definitions, including scales and rotations. But we are keeping it simple here with only a translation transform, which simply pushes the whole g group over and down by some amount.

Translation transforms are specified with the easy syntax of translate(x,y), where x and y are, obviously, the number of horizontal and vertical pixels by which to translate the element.

Yes, they're both JavaScript, you can use whichever functions are appropriate for the situation.

In this case you can just put the code in a document.ready handler, like this:

$(function() {
  var canvas = document.getElementById("canvas");
  if (canvas.getContext) {
    var ctx = canvas.getContext("2d");

    ctx.fillStyle = "rgb(200,0,0)";
    ctx.fillRect (10, 10, 55, 50);

    ctx.fillStyle = "rgba(0, 0, 200, 0.5)";
    ctx.fillRect (30, 30, 55, 50);
  }
});

Run a test.

   string coerce:          7.42296099663

   string fail coerce:     7.14159703255
   string fail cast:       7.87444186211

This was a test that ran each scenario 10,000,000 times. :-)

Co-ercion is 0 + "123"

Casting is (integer)"123"

I think Co-ercion is a tiny bit faster. Oh, and trying 0 + array('123') is a fatal error in PHP. You might want your code to check the type of the supplied value.

My test code is below.

function test_string_coerce($s) {
    return 0 + $s;
}

function test_string_cast($s) {
    return (integer)$s;
}

$iter = 10000000;

print "-- running each text $iter times.\n";

// string co-erce
$string_coerce = new Timer;
$string_coerce->Start();

print "String Coerce test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_coerce('123');
}

$string_coerce->Stop();

// string cast
$string_cast = new Timer;
$string_cast->Start();

print "String Cast test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_cast('123');
}

$string_cast->Stop();

// string co-erce fail.
$string_coerce_fail = new Timer;
$string_coerce_fail->Start();

print "String Coerce fail test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_coerce('hello');
}

$string_coerce_fail->Stop();

// string cast fail
$string_cast_fail = new Timer;
$string_cast_fail->Start();

print "String Cast fail test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_cast('hello');
}

$string_cast_fail->Stop();

}

This is an improvement to a previous answer. It adds support for values with varying lengths and rows with a varying number of cells. For example:

You're seeing firsthand one of the cons of Lua having only one data structure---you have to roll your own. If you stick with Lua you will gradually accumulate a library of functions that manipulate tables in the way you like to do things. My library includes a list-to-set conversion and a higher-order list-searching function:

function table.set(t) -- set of list
  local u = { }
  for _, v in ipairs(t) do u[v] = true end
  return u
end

function table.find(f, l) -- find element v of l satisfying f(v)
  for _, v in ipairs(l) do
    if f(v) then
      return v
    end
  end
  return nil
end

One more important thing to realise: if you see iso-8859-1, it probably refers to Windows-1252 rather than ISO/IEC 8859-1. They differ in the range 0x80–0x9F, where ISO 8859-1 has the C1 control codes, and Windows-1252 has useful visible characters instead.

For example, ISO 8859-1 has 0x85 as a control character (in Unicode, U+0085, ``), while Windows-1252 has a horizontal ellipsis (in Unicode, U+2026 HORIZONTAL ELLIPSIS, …).

The WHATWG Encoding spec (as used by HTML) expressly declares iso-8859-1 to be a label for windows-1252, and web browsers do not support ISO 8859-1 in any way: the HTML spec says that all encodings in the Encoding spec must be supported, and no more.

Also of interest, HTML numeric character references essentially use Windows-1252 for 8-bit values rather than Unicode code points; per https://html.spec.whatwg.org/#numeric-character-reference-end-state, … will produce U+2026 rather than U+0085.

It is going to write the value of your property model.Destination

This is by design. You'll want to populate your Destination property with the value you want in your controller before returning your view.

The difference in assignment operators is clearer when you use them to set an argument value in a function call. For example:

median(x = 1:10)
x   
## Error: object 'x' not found

In this case, x is declared within the scope of the function, so it does not exist in the user workspace.

median(x <- 1:10)
x    
## [1]  1  2  3  4  5  6  7  8  9 10

In this case, x is declared in the user workspace, so you can use it after the function call has been completed.

There is a general preference among the R community for using <- for assignment (other than in function signatures) for compatibility with (very) old versions of S-Plus. Note that the spaces help to clarify situations like

x<-3
# Does this mean assignment?
x <- 3
# Or less than?
x < -3

Most R IDEs have keyboard shortcuts to make <- easier to type. Ctrl + = in Architect, Alt + - in RStudio (Option + - under macOS), Shift + - (underscore) in emacs+ESS.

If you prefer writing = to <- but want to use the more common assignment symbol for publicly released code (on CRAN, for example), then you can use one of the tidy_* functions in the formatR package to automatically replace = with <-.

library(formatR)
tidy_source(text = "x=1:5", arrow = TRUE)
## x <- 1:5

The answer to the question "Why does x <- y = 5 throw an error but not x <- y <- 5?" is "It's down to the magic contained in the parser". R's syntax contains many ambiguous cases that have to be resolved one way or another. The parser chooses to resolve the bits of the expression in different orders depending on whether = or <- was used.

To understand what is happening, you need to know that assignment silently returns the value that was assigned. You can see that more clearly by explicitly printing, for example print(x <- 2 + 3).

Secondly, it's clearer if we use prefix notation for assignment. So

x <- 5
`<-`(x, 5)  #same thing

y = 5
`=`(y, 5)   #also the same thing

The parser interprets x <- y <- 5 as

`<-`(x, `<-`(y, 5))

We might expect that x <- y = 5 would then be

`<-`(x, `=`(y, 5))

but actually it gets interpreted as

`=`(`<-`(x, y), 5)

This is because = is lower precedence than <-, as shown on the ?Syntax help page.

Simply try this for all properties of an object,

foreach (var prop in myobject.GetType().GetProperties(BindingFlags.Public|BindingFlags.Instance))
{
   var propertyName = prop.Name;
   var propertyValue = myobject.GetType().GetProperty(propertyName).GetValue(myobject, null);

   //Debug.Print(prop.Name);
   //Debug.Print(Functions.convertNullableToString(propertyValue));

   Debug.Print(string.Format("Property Name={0} , Value={1}", prop.Name, Functions.convertNullableToString(propertyValue)));
}

NOTE: Functions.convertNullableToString() is custom function using for convert NULL value into string.empty.

How about filtering these errors ?

With the regex filter bellow, we can dismiss cast_sender.js errors :

^((?!cast_sender).)*$

Do not forget to check Regex box.

Another quick solution is to "Hide network messages".

You can use as many joins as you want, however, the more you use the more it will impact performance

2 ways that I know of :

USING PPM :

With Windows (ActivePerl) I've used ppm

from the command line type ppm. At the ppm prompt ...

ppm> install foo

or

ppm> search foo

to get a list of foo modules available. Type help for all the commands

USING CPAN :

you can also use CPAN like this (*nix systems) :

perl -MCPAN -e 'shell'

gets you a prompt

cpan>

at the prompt ...

cpan> install foo  (again to install the foo module)

type h to get a list of commands for cpan

sdas is being read as a variable. To input a string you need " "

Package

I used html-pdf

Easy to use and allows not only to save pdf as file, but also pipe pdf content to a WriteStream (so I could stream it directly to Google Storage to save there my reports).

Using css + images

It takes css into account. The only problem I faced - it ignored my images. The solution I found was to replace url in src attrribute value by base64, e.g.

<img src="data:image/png;base64,iVBOR...kSuQmCC">

You can do it with your code or to use one of online converters, e.g. https://www.base64-image.de/

Compile valid html code from html fragment + css

1. I had to get a fragment of my html document (I just appiled .html() method on jQuery selector).
2. Then I've read the content of the relevant css file.

Using this two values (stored in variables html and css accordingly) I've compiled a valid html code using Template string

var htmlContent = `
<!DOCTYPE html>
<html>
  <head>
    <style>
      ${css}
    </style>
  </head>
  <body id=direct-sellers-bill>
    ${html}
  </body>
</html>`

and passed it to create method of html-pdf.

String is a reference type, so you don't need to (and cannot) use Nullable<T> here. Just declare typeOfContract as string and simply check for null after getting it from the query string. Or use String.IsNullOrEmpty if you want to handle empty string values the same as null.

The about:debug (or chrome:\\debug both of which say page cannot be found, but enable the Debug menu in the settings) when tried on Chrome or Opera on Android KitKat 4.4.2 on a Samsung Tab

If you have ROOT permissions on your device, you can view the console messages directly on the device. Use an app like CatLog to view the log output - https://play.google.com/store/apps/details?id=com.nolanlawson.logcat&hl=en This will let you view all logcat activity.

In Android KitKat/4.4.2, the browser console is output to the Chromium channel. You could filter by "Chromium" to get all browser activity (include browser's internal activity), or simply filter by "Console" to only see the Browser console log.

controller_path holds the path of the controller used to serve the current view. (ie: admin/settings).

and

controller_name holds the name of the controller used to serve the current view. (ie: settings).

Here is one that hard fails after 4 attempts, and waits 2 seconds between attempts. Change as you wish to get what you want form this one:

from time import sleep

for x in range(0, 4):  # try 4 times
    try:
        # msg.send()
        # put your logic here
        str_error = None
    except Exception as str_error:
        pass

    if str_error:
        sleep(2)  # wait for 2 seconds before trying to fetch the data again
    else:
        break

Here is an example with backoff:

from time import sleep

sleep_time = 2
num_retries = 4
for x in range(0, num_retries):  
    try:
        # put your logic here
        str_error = None
    except Exception as str_error:
        pass

    if str_error:
        sleep(sleep_time)  # wait before trying to fetch the data again
        sleep_time *= 2  # Implement your backoff algorithm here i.e. exponential backoff
    else:
        break

Your code should work, but you can also try:

Grinn / ThePirat solution works well.

I did not like that it new'd the Include method on bundle, and that it created temporary files in the content directory. (they ended up getting checked in, deployed, then the service wouldn't start!)

So to follow the design of Bundling, I elected to perform essentially the same code, but in an IBundleTransform implementation::

class StyleRelativePathTransform
    : IBundleTransform
{
    public StyleRelativePathTransform()
    {
    }

    public void Process(BundleContext context, BundleResponse response)
    {
        response.Content = String.Empty;

        Regex pattern = new Regex(@"url\s*\(\s*([""']?)([^:)]+)\1\s*\)", RegexOptions.IgnoreCase);
        // open each of the files
        foreach (FileInfo cssFileInfo in response.Files)
        {
            if (cssFileInfo.Exists)
            {
                // apply the RegEx to the file (to change relative paths)
                string contents = File.ReadAllText(cssFileInfo.FullName);
                MatchCollection matches = pattern.Matches(contents);
                // Ignore the file if no match 
                if (matches.Count > 0)
                {
                    string cssFilePath = cssFileInfo.DirectoryName;
                    string cssVirtualPath = context.HttpContext.RelativeFromAbsolutePath(cssFilePath);
                    foreach (Match match in matches)
                    {
                        // this is a path that is relative to the CSS file
                        string relativeToCSS = match.Groups[2].Value;
                        // combine the relative path to the cssAbsolute
                        string absoluteToUrl = Path.GetFullPath(Path.Combine(cssFilePath, relativeToCSS));

                        // make this server relative
                        string serverRelativeUrl = context.HttpContext.RelativeFromAbsolutePath(absoluteToUrl);

                        string quote = match.Groups[1].Value;
                        string replace = String.Format("url({0}{1}{0})", quote, serverRelativeUrl);
                        contents = contents.Replace(match.Groups[0].Value, replace);
                    }
                }
                // copy the result into the response.
                response.Content = String.Format("{0}\r\n{1}", response.Content, contents);
            }
        }
    }
}

And then wrapped this up in a Bundle Implemetation:

public class StyleImagePathBundle 
    : Bundle
{
    public StyleImagePathBundle(string virtualPath)
        : base(virtualPath)
    {
        base.Transforms.Add(new StyleRelativePathTransform());
        base.Transforms.Add(new CssMinify());
    }

    public StyleImagePathBundle(string virtualPath, string cdnPath)
        : base(virtualPath, cdnPath)
    {
        base.Transforms.Add(new StyleRelativePathTransform());
        base.Transforms.Add(new CssMinify());
    }
}

Sample Usage:

static void RegisterBundles(BundleCollection bundles)
{
...
    bundles.Add(new StyleImagePathBundle("~/bundles/Bootstrap")
            .Include(
                "~/Content/css/bootstrap.css",
                "~/Content/css/bootstrap-responsive.css",
                "~/Content/css/jquery.fancybox.css",
                "~/Content/css/style.css",
                "~/Content/css/error.css",
                "~/Content/validation.css"
            ));

Here is my extension method for RelativeFromAbsolutePath:

   public static string RelativeFromAbsolutePath(this HttpContextBase context, string path)
    {
        var request = context.Request;
        var applicationPath = request.PhysicalApplicationPath;
        var virtualDir = request.ApplicationPath;
        virtualDir = virtualDir == "/" ? virtualDir : (virtualDir + "/");
        return path.Replace(applicationPath, virtualDir).Replace(@"\", "/");
    }

I needed to fix accepted answer above to make it work using that instead of this pointer. This within the scope of map function didn't have doSomething function defined.

var Parent = React.createClass({
doSomething: function() {
    console.log('doSomething!');
},

render: function() {
    var that = this;
    var childrenWithProps = React.Children.map(this.props.children, function(child) {
        return React.cloneElement(child, { doSomething: that.doSomething });
    });

    return <div>{childrenWithProps}</div>
}})

Update: this fix is for ECMAScript 5, in ES6 there is no need in var that=this

Note that the default when you make a class is not public as far as packages are considered. Make sure that you actually write public class [MyClass] { when defining your class. I've made this mistake more times than I care to admit.

You need to provide an IFormatProvider:

@String.Format(new CultureInfo("en-US"), "{0:C}", @price)

the percent should be relative to an absolute size, try this :

table {
  width:200px;
}

td {
  width:65%;
  border:1px solid black;
}

<table>
  <tr>
    <td>Testasdas 3123 1 dasd as da</td>
    <td>A long string blah blah blah</td>
  </tr>
</table>
    

for only date in specific format

    let dateFormatter1 = NSDateFormatter()
    dateFormatter1.dateStyle = .MediumStyle
    dateFormatter1.timeStyle = .NoStyle
    dateFormatter1.dateFormat = "dd-MM-yyyy"
    let date = dateFormatter1.stringFromDate(NSDate())

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

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

using System;
using System.Diagnostics;
using System.IO;
using System.IO.Pipes;
using System.Threading;
using System.Threading.Tasks;
using Newtonsoft.Json;

namespace TestJsonStream {
    class Program {
        static void Main(string[] args) {
            using(var writeStream = new AnonymousPipeServerStream(PipeDirection.Out, HandleInheritability.None)) {
                string pipeHandle = writeStream.GetClientHandleAsString();
                var writeTask = Task.Run(() => {
                    using(var sw = new StreamWriter(writeStream))
                    using(var writer = new JsonTextWriter(sw)) {
                        var ser = new JsonSerializer();
                        writer.WriteStartArray();
                        for(int i = 0; i < 25; i++) {
                            ser.Serialize(writer, new DataItem { Item = i });
                            writer.Flush();
                            Thread.Sleep(500);
                        }
                        writer.WriteEnd();
                        writer.Flush();
                    }
                });
                var readTask = Task.Run(() => {
                    var sw = new Stopwatch();
                    sw.Start();
                    using(var readStream = new AnonymousPipeClientStream(pipeHandle))
                    using(var sr = new StreamReader(readStream))
                    using(var reader = new JsonTextReader(sr)) {
                        var ser = new JsonSerializer();
                        if(!reader.Read() || reader.TokenType != JsonToken.StartArray) {
                            throw new Exception("Expected start of array");
                        }
                        while(reader.Read()) {
                            if(reader.TokenType == JsonToken.EndArray) break;
                            var item = ser.Deserialize<DataItem>(reader);
                            Console.WriteLine("[{0}] Received item: {1}", sw.Elapsed, item);
                        }
                    }
                });
                Task.WaitAll(writeTask, readTask);
                writeStream.DisposeLocalCopyOfClientHandle();
            }
        }

        class DataItem {
            public int Item { get; set; }
            public override string ToString() {
                return string.Format("{{ Item = {0} }}", Item);
            }
        }
    }
}

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

You can't just return an array of objects because there's nothing telling React how to render that. You'll need to return an array of components or elements like:

render: function() {
  return (
    <span>
      // This will go through all the elements in arrayFromJson and
      // render each one as a <SomeComponent /> with data from the object
      {this.state.arrayFromJson.map(function(object) {
        return (
          <SomeComponent key={object.id} data={object} />
        );
      })}
    </span>
  );
}

This code works on ROOTED phones:

public class MainActivity extends AppCompatActivity {

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

        String[] cmds = {"cd /system/bin" ,"settings put secure location_providers_allowed +gps"};
        try {
            Process p = Runtime.getRuntime().exec("su");
            DataOutputStream os = new DataOutputStream(p.getOutputStream());
            for (String tmpCmd : cmds) {
                os.writeBytes(tmpCmd + "\n");
            }
            os.writeBytes("exit\n");
            os.flush();
        }
        catch (IOException e){
            e.printStackTrace();
        }
    }
}

For turning off GPS you can use this command instead

settings put secure location_providers_allowed -gps

You can also toggle network accuracy using the following commands: for turning on use:

settings put secure location_providers_allowed +network

and for turning off you can use:

settings put secure location_providers_allowed -network

From XML.com:

Like xsl:if instructions, xsl:when elements can have more elaborate contents between their start- and end-tags—for example, literal result elements, xsl:element elements, or even xsl:if and xsl:choose elements—to add to the result tree. Their test expressions can also use all the tricks and operators that the xsl:if element's test attribute can use, such as and, or, and function calls, to build more complex boolean expressions.

Use the one with mysql_fetch_row because "For SELECT, SHOW, DESCRIBE, EXPLAIN and other statements returning resultset, mysql_query() returns a resource on success, or FALSE on error.

For other type of SQL statements, INSERT, UPDATE, DELETE, DROP, etc, mysql_query() returns TRUE on success or FALSE on error. "

Finally I could successfully compile a program with C++ connector in Ubuntu 12.04 I have installed the connector using this command

'apt-get install libmysqlcppconn-dev'

Initially I faced the same problem with "undefined reference to `get_driver_instance' " to solve this I declare my driver instance variable of MySQL_Driver type. For ready reference this type is defined in mysql_driver.h file. Here is the code snippet I used in my program.

sql::mysql::MySQL_Driver *driver;
try {     
    driver = sql::mysql::get_driver_instance();
}

and I compiled the program with -l mysqlcppconn linker option

and don't forget to include this header

#include "mysql_driver.h" 

With commas separating them, just like parameters without default values.

int func( int x = 0, int y = 0 );

func(); // doesn't pass optional parameters, defaults are used, x = 0 and y = 0

func(1, 2); // provides optional parameters, x = 1 and y = 2

Allow an analysis.

#include <iostream>   // not #include "iostream"
using namespace std;  // in this case okay, but never do that in header files

class A
{
 public:
  void f() { cout<<"f()\n"; }
};

int main()
{
 /*
 // A a; //this works
 A *a = new A(); //this doesn't
 a.f(); // "f has not been declared"
 */ // below


 // system("pause");  <-- Don't do this. It is non-portable code. I guess your 
 //                       teacher told you this?
 //                       Better: In your IDE there is prolly an option somewhere
 //                               to not close the terminal/console-window.
 //                       If you compile on a CLI, it is not needed at all.
}

As a general advice:

0) Prefer automatic variables
  int a;
  MyClass myInstance;
  std::vector<int> myIntVector;

1) If you need data sharing on big objects down 
   the call hierarchy, prefer references:

  void foo (std::vector<int> const &input) {...}
  void bar () { 
       std::vector<int> something;
       ...
       foo (something);
  }


2) If you need data sharing up the call hierarchy, prefer smart-pointers
   that automatically manage deletion and reference counting.

3) If you need an array, use std::vector<> instead in most cases.
   std::vector<> is ought to be the one default container.

4) I've yet to find a good reason for blank pointers.

   -> Hard to get right exception safe

       class Foo {
           Foo () : a(new int[512]), b(new int[512]) {}
           ~Foo() {
               delete [] b;
               delete [] a;
           }
       };

       -> if the second new[] fails, Foo leaks memory, because the
          destructor is never called. Avoid this easily by using 
          one of the standard containers, like std::vector, or
          smart-pointers.

As a rule of thumb: If you need to manage memory on your own, there is generally a superiour manager or alternative available already, one that follows the RAII principle.

i couldn't change the permissions on the sharepoint i'm using but got a round it by uploading .url files with the drag and drop multiple files uploader.

Using the normal upload didn't work because they are intepreted by the file open dialog when you try to open them singly so it just tries to open the target not the .url file.

.url files can be made by saving a favourite with internet exploiter.

These are the versions of C# known about at the time of this writing:

• C# 1.0 released with .NET 1.0 and VS2002 (January 2002)
• C# 1.2 (bizarrely enough); released with .NET 1.1 and VS2003 (April 2003). First version to call Dispose on IEnumerators which implemented IDisposable. A few other small features.
• C# 2.0 released with .NET 2.0 and VS2005 (November 2005). Major new features: generics, anonymous methods, nullable types, iterator blocks

Minor features: relax ordering of ref and partial modifiers, parameter null checking, lambda discard parameters, native ints, attributes on local functions, function pointers, static lambdas, extension GetEnumerator, module initializers, extending partial.

In response to the OP's question:

What are the correct version numbers for C#? What came out when? Why can't I find any answers about C# 3.5?

There is no such thing as C# 3.5 - the cause of confusion here is that the C# 3.0 is present in .NET 3.5. The language and framework are versioned independently, however - as is the CLR, which is at version 2.0 for .NET 2.0 through 3.5, .NET 4 introducing CLR 4.0, service packs notwithstanding. The CLR in .NET 4.5 has various improvements, but the versioning is unclear: in some places it may be referred to as CLR 4.5 (this MSDN page used to refer to it that way, for example), but the Environment.Version property still reports 4.0.xxx.

As of May 3, 2017, the C# Language Team created a history of C# versions and features on their GitHub repository: Features Added in C# Language Versions. There is also a page that tracks upcoming and recently implemented language features.

Alternatively, you can use some java-to-c translator (e.g., JCGO) and compile the generated C files to a native binary (.exe) file for the target platform.

The valid way is:

disabled="disabled"

Browsers also might accept disabled="" but I would recommend you the first approach.

Now this being said I would recommend you writing a custom HTML helper in order to encapsulate this disabling functionality into a reusable piece of code:

using System;
using System.Linq.Expressions;
using System.Web;
using System.Web.Mvc;
using System.Web.Mvc.Html;
using System.Web.Routing;

public static class HtmlExtensions
{
    public static IHtmlString MyTextBoxFor<TModel, TProperty>(
        this HtmlHelper<TModel> htmlHelper, 
        Expression<Func<TModel, TProperty>> expression, 
        object htmlAttributes, 
        bool disabled
    )
    {
        var attributes = new RouteValueDictionary(htmlAttributes);
        if (disabled)
        {
            attributes["disabled"] = "disabled";
        }
        return htmlHelper.TextBoxFor(expression, attributes);
    }
}

which you could use like this:

@Html.MyTextBoxFor(
    model => model.ExpireDate, 
    new { 
        style = "width: 70px;", 
        maxlength = "10", 
        id = "expire-date" 
    }, 
    Model.ExpireDate == null
)

and you could bring even more intelligence into this helper:

public static class HtmlExtensions
{
    public static IHtmlString MyTextBoxFor<TModel, TProperty>(
        this HtmlHelper<TModel> htmlHelper,
        Expression<Func<TModel, TProperty>> expression,
        object htmlAttributes
    )
    {
        var attributes = new RouteValueDictionary(htmlAttributes);
        var metaData = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
        if (metaData.Model == null)
        {
            attributes["disabled"] = "disabled";
        }
        return htmlHelper.TextBoxFor(expression, attributes);
    }
}

so that now you no longer need to specify the disabled condition:

@Html.MyTextBoxFor(
    model => model.ExpireDate, 
    new { 
        style = "width: 70px;", 
        maxlength = "10", 
        id = "expire-date" 
    }
)

If it suits anyone, here are some brief guidelines for adding environment variables permanently.

vi ~/.bash_profile

Add the variables to the file:

export DISPLAY=:0
export JAVA_HOME=~/opt/openjdk11

Immediately apply all changes:

source ~/.bash_profile

Note that since git1.7.11 ([ANNOUNCE] Git 1.7.11.rc1 and release note, June 2012) mentions:

"git push --recurse-submodules" learned to optionally look into the histories of submodules bound to the superproject and push them out.

Probably done after this patch and the --on-demand option:

recurse-submodules=<check|on-demand>::

Make sure all submodule commits used by the revisions to be pushed are available on a remote tracking branch.

• If check is used, it will be checked that all submodule commits that changed in the revisions to be pushed are available on a remote.
  Otherwise the push will be aborted and exit with non-zero status.
• If on-demand is used, all submodules that changed in the revisions to be pushed will be pushed.
  If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status.

So you could push everything in one go with (from the parent repo) a:

git push --recurse-submodules=on-demand

This option only works for one level of nesting. Changes to the submodule inside of another submodule will not be pushed.

With git 2.7 (January 2016), a simple git push will be enough to push the parent repo... and all its submodules.

See commit d34141c, commit f5c7cd9 (03 Dec 2015), commit f5c7cd9 (03 Dec 2015), and commit b33a15b (17 Nov 2015) by Mike Crowe (mikecrowe).
^{(Merged by Junio C Hamano -- gitster -- in commit 5d35d72, 21 Dec 2015)}

push: add recurseSubmodules config option

The --recurse-submodules command line parameter has existed for some time but it has no config file equivalent.

Following the style of the corresponding parameter for git fetch, let's invent push.recurseSubmodules to provide a default for this parameter.
This also requires the addition of --recurse-submodules=no to allow the configuration to be overridden on the command line when required.

The most straightforward way to implement this appears to be to make push use code in submodule-config in a similar way to fetch.

The git config doc now include:

push.recurseSubmodules:

Make sure all submodule commits used by the revisions to be pushed are available on a remote-tracking branch.

• If the value is 'check', then Git will verify that all submodule commits that changed in the revisions to be pushed are available on at least one remote of the submodule. If any commits are missing, the push will be aborted and exit with non-zero status.
• If the value is 'on-demand' then all submodules that changed in the revisions to be pushed will be pushed. If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status. -
• If the value is 'no' then default behavior of ignoring submodules when pushing is retained.

You may override this configuration at time of push by specifying '--recurse-submodules=check|on-demand|no'.

So:

git config push.recurseSubmodules on-demand
git push

Git 2.12 (Q1 2017)

git push --dry-run --recurse-submodules=on-demand will actually work.

See commit 0301c82, commit 1aa7365 (17 Nov 2016) by Brandon Williams (mbrandonw).
^{(Merged by Junio C Hamano -- gitster -- in commit 12cf113, 16 Dec 2016)}

push run with --dry-run doesn't actually (Git 2.11 Dec. 2016 and lower/before) perform a dry-run when push is configured to push submodules on-demand.
Instead all submodules which need to be pushed are actually pushed to their remotes while any updates for the superproject are performed as a dry-run.
This is a bug and not the intended behaviour of a dry-run.

Teach push to respect the --dry-run option when configured to recursively push submodules 'on-demand'.
This is done by passing the --dry-run flag to the child process which performs a push for a submodules when performing a dry-run.

And still in Git 2.12, you now havea "--recurse-submodules=only" option to push submodules out without pushing the top-level superproject.

See commit 225e8bf, commit 6c656c3, commit 14c01bd (19 Dec 2016) by Brandon Williams (mbrandonw).
^{(Merged by Junio C Hamano -- gitster -- in commit 792e22e, 31 Jan 2017)}

So in simple words: Over clause can be used to select non aggregated values along with Aggregated ones.

Partition BY, ORDER BY inside, and ROWS or RANGE are part of OVER() by clause.

partition by is used to partition data and then perform these window, aggregated functions, and if we don't have partition by the then entire result set is considered as a single partition.

OVER clause can be used with Ranking Functions(Rank, Row_Number, Dense_Rank..), Aggregate Functions like (AVG, Max, Min, SUM...etc) and Analytics Functions like (First_Value, Last_Value, and few others).

Let's See basic syntax of OVER clause

OVER (   
       [ <PARTITION BY clause> ]  
       [ <ORDER BY clause> ]   
       [ <ROW or RANGE clause> ]  
      )  

PARTITION BY: It is used to partition data and perform operations on groups with the same data.

ORDER BY: It is used to define the logical order of data in Partitions. When we don't specify Partition, entire resultset is considered as a single partition

: This can be used to specify what rows are supposed to be considered in a partition when performing the operation.

Let's take an example:

Here is my dataset:

Id          Name                                               Gender     Salary
----------- -------------------------------------------------- ---------- -----------
1           Mark                                               Male       5000
2           John                                               Male       4500
3           Pavan                                              Male       5000
4           Pam                                                Female     5500
5           Sara                                               Female     4000
6           Aradhya                                            Female     3500
7           Tom                                                Male       5500
8           Mary                                               Female     5000
9           Ben                                                Male       6500
10          Jodi                                               Female     7000
11          Tom                                                Male       5500
12          Ron                                                Male       5000

So let me execute different scenarios and see how data is impacted and I'll come from difficult syntax to simple one

Select *,SUM(salary) Over(order by salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) as sum_sal from employees

Id          Name                                               Gender     Salary      sum_sal

3           Pavan                                              Male       5000        32000

7           Tom                                                Male       5500        48500
4           Pam                                                Female     5500        48500
9           Ben                                                Male       6500        55000
10          Jodi                                               Female     7000        62000

Just observe the sum_sal part. Here I am using order by Salary and using "RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW". In this case, we are not using partition so entire data will be treated as one partition and we are ordering on salary. And the important thing here is UNBOUNDED PRECEDING AND CURRENT ROW. This means when we are calculating the sum, from starting row to the current row for each row. But if we see rows with salary 5000 and name="Pavan", ideally it should be 17000 and for salary=5000 and name=Mark, it should be 22000. But as we are using RANGE and in this case, if it finds any similar elements then it considers them as the same logical group and performs an operation on them and assigns value to each item in that group. That is the reason why we have the same value for salary=5000. The engine went up to salary=5000 and Name=Ron and calculated sum and then assigned it to all salary=5000.

Select *,SUM(salary) Over(order by salary ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) as sum_sal from employees

So with ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW The difference is for same value items instead of grouping them together, It calculates SUM from starting row to current row and it doesn't treat items with same value differently like RANGE

Select *,SUM(salary) Over(order by salary) as sum_sal from employees

These results are the same as

Select *, SUM(salary) Over(order by salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) as sum_sal from employees

That is because Over(order by salary) is just a short cut of Over(order by salary RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) So wherever we simply specify Order by without ROWS or RANGE it is taking RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW as default.

Note: This is applicable only to Functions that actually accept RANGE/ROW. For example, ROW_NUMBER and few others don't accept RANGE/ROW and in that case, this doesn't come into the picture.

Till now we saw that Over clause with an order by is taking Range/ROWS and syntax looks something like this RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW And it is actually calculating up to the current row from the first row. But what If it wants to calculate values for the entire partition of data and have it for each column (that is from 1st row to last row). Here is the query for that

Select *,sum(salary) Over(order by salary ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) as sum_sal from employees

Instead of CURRENT ROW, I am specifying UNBOUNDED FOLLOWING which instructs the engine to calculate till the last record of partition for each row.

Now coming to your point on what is OVER() with empty braces?

It is just a short cut for Over(order by salary ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING)

Here we are indirectly specifying to treat all my resultset as a single partition and then perform calculations from the first record to the last record of each partition.

Select *,Sum(salary) Over() as sum_sal from employees

B4i is a new development tool that creates native iOS apps. It runs on Windows. When a full compilation is required (in most cases it is not required) the project is compiled on a hosted builder. Each compilation takes about 5 seconds. B4i

A workaround - at least for the minimum size: You can use grid to manage the frames contained in root and make them follow the grid size by setting sticky='nsew'. Then you can use root.grid_rowconfigure and root.grid_columnconfigure to set values for minsize like so:

from tkinter import Frame, Tk

class MyApp():
    def __init__(self):
        self.root = Tk()

        self.my_frame_red = Frame(self.root, bg='red')
        self.my_frame_red.grid(row=0, column=0, sticky='nsew')

        self.my_frame_blue = Frame(self.root, bg='blue')
        self.my_frame_blue.grid(row=0, column=1, sticky='nsew')

        self.root.grid_rowconfigure(0, minsize=200, weight=1)
        self.root.grid_columnconfigure(0, minsize=200, weight=1)
        self.root.grid_columnconfigure(1, weight=1)

        self.root.mainloop()

if __name__ == '__main__':
    app = MyApp()

But as Brian wrote (in 2010 :D) you can still resize the window to be smaller than the frame if you don't limit its minsize.

In a BST, all values descending on the left side of a node are less than (or equal to, see later) the node itself. Similarly, all values descending on the right side of a node are greater than (or equal to) that node value^(a).

Some BSTs may choose to allow duplicate values, hence the "or equal to" qualifiers above. The following example may clarify:

     14
    /  \
  13    22
 /     /  \
1    16    29
          /  \
        28    29

This shows a BST that allows duplicates^(b) - you can see that to find a value, you start at the root node and go down the left or right subtree depending on whether your search value is less than or greater than the node value.

This can be done recursively with something like:

def hasVal (node, srchval):
    if node == NULL:
         return false
    if node.val == srchval:
        return true
    if node.val > srchval:
        return hasVal (node.left, srchval)
    return hasVal (node.right, srchval)

and calling it with:

foundIt = hasVal (rootNode, valToLookFor)

Duplicates add a little complexity since you may need to keep searching once you've found your value, for other nodes of the same value. Obviously that doesn't matter for hasVal since it doesn't matter how many there are, just whether at least one exists. It will however matter for things like countVal, since it needs to know how many there are.

^(a) You could actually sort them in the opposite direction should you so wish provided you adjust how you search for a specific key. A BST need only maintain some sorted order, whether that's ascending or descending (or even some weird multi-layer-sort method like all odd numbers ascending, then all even numbers descending) is not relevant.

^(b) Interestingly, if your sorting key uses the entire value stored at a node (so that nodes containing the same key have no other extra information to distinguish them), there can be performance gains from adding a count to each node, rather than allowing duplicate nodes.

The main benefit is that adding or removing a duplicate will simply modify the count rather than inserting or deleting a new node (an action that may require re-balancing the tree).

So, to add an item, you first check if it already exists. If so, just increment the count and exit. If not, you need to insert a new node with a count of one then rebalance.

To remove an item, you find it then decrement the count - only if the resultant count is zero do you then remove the actual node from the tree and rebalance.

Searches are also quicker given there are fewer nodes but that may not be a large impact.

For example, the following two trees (non-counting on the left, and counting on the right) would be equivalent (in the counting tree, i.c means c copies of item i):

     __14__                    ___22.2___
    /      \                  /          \
  14        22             7.1            29.1
 /  \      /  \           /   \          /    \
1    14  22    29      1.1     14.3  28.1      30.1
 \            /  \
  7         28    30

Removing the leaf-node 22 from the left tree would involve rebalancing (since it now has a height differential of two) the resulting 22-29-28-30 subtree such as below (this is one option, there are others that also satisfy the "height differential must be zero or one" rule):

\                      \
 22                     29
   \                   /  \
    29      -->      28    30
   /  \             /
 28    30         22

Doing the same operation on the right tree is a simple modification of the root node from 22.2 to 22.1 (with no rebalancing required).

EDIT: This will not work for network URLs (see comments)

As of iOS 5, there is a new NSURL instance method:

- (BOOL)checkResourceIsReachableAndReturnError:(NSError **)error

Point it to the website you care about or point it to apple.com; I think it is the new one-line call to see if the internet is working on your device.

Go to Path C:\ProgramData\Oracle\Java\javapath (This path is in my case might be different in your case). Rename the folder ORACLE with other name line ORACLE_OLD. And Restart the STS/IDE . This works for me

tl;dr

With JDBC 4.2 or later and java 8 or later:

myPreparedStatement.setObject( … , myLocalDate  )

…and…

myResultSet.getObject( … , LocalDate.class )

Details

The Answer by Vargas is good about mentioning java.time types but refers only to converting to java.sql.Date. No need to convert if your driver is updated.

java.time

The java.time framework is built into Java 8 and later. These classes supplant the old troublesome date-time classes such as java.util.Date, .Calendar, & java.text.SimpleDateFormat. The Joda-Time team also advises migration to java.time.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations.

Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport and further adapted to Android in ThreeTenABP.

LocalDate

In java.time, the java.time.LocalDate class represents a date-only value without time-of-day and without time zone.

If using a JDBC driver compliant with JDBC 4.2 or later spec, no need to use the old java.sql.Date class. You can pass/fetch LocalDate objects directly to/from your database via PreparedStatement::setObject and ResultSet::getObject.

LocalDate localDate = LocalDate.now( ZoneId.of( "America/Montreal" ) );
myPreparedStatement.setObject( 1 , localDate  );

…and…

LocalDate localDate = myResultSet.getObject( 1 , LocalDate.class );

Before JDBC 4.2, convert

If your driver cannot handle the java.time types directly, fall back to converting to java.sql types. But minimize their use, with your business logic using only java.time types.

New methods have been added to the old classes for conversion to/from java.time types. For java.sql.Date see the valueOf and toLocalDate methods.

java.sql.Date sqlDate = java.sql.Date.valueOf( localDate );

…and…

LocalDate localDate = sqlDate.toLocalDate();

Placeholder value

Be wary of using 0000-00-00 as a placeholder value as shown in your Question’s code. Not all databases and other software can handle going back that far in time. I suggest using something like the commonly-used Unix/Posix epoch reference date of 1970, 1970-01-01.

LocalDate EPOCH_DATE = LocalDate.ofEpochDay( 0 ); // 1970-01-01 is day 0 in Epoch counting.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Solution(s) for this, found in the official wampserver.com forums:

SOLUTION #1:

This problem is caused by Windows (7) in combination with any software that also uses port 80 (like Skype or IIS (which is installed on most developer machines)). A video solution can be found here (34.500+ views, damn, this seems to be a big thing ! EDIT: The video now has ~60.000 views ;) )

To make it short: open command line tool, type "netstat -aon" and look for any lines that end of ":80". Note thatPID on the right side. This is the process id of the software which currently usesport 80. Press AltGr + Ctrl + Del to get into the Taskmanager. Switch to the tab where you can see all services currently running, ordered by PID. Search for that PID you just notices and stop that thing (right click). To prevent this in future, you should config the software's port settings (skype can do that).

SOLUTION #2:

left click the wamp icon in the taskbar, go to apache > httpd.conf and edit this file: change "listen to port .... 80" to 8080. Restart. Done !

SOLUTION #3:

Port 80 blocked by "Microsoft Web Deployment Service", simply deinstall this, more info here

By the way, it's not Microsoft's fault, it's a stupid usage of ports by most WAMP stacks.

IMPORTANT: you have to use localhost or 127.0.0.1 now with port 8080, this means 127.0.0.1:8080 or localhost:8080.

If you manually write out the query with static date values (e.g. '2009-10-29 13:13:07.440') do you get any rows?

So, you are saying that the following two queries produce correct results:

SELECT DISTINCT pat.PublicationID
FROM PubAdvTransData AS pat 
    INNER JOIN PubAdvertiser AS pa 
        ON pat.AdvTransID = pa.AdvTransID
WHERE (pat.LastAdDate > '2009-10-29 13:13:07.440') AND (pa.AdvertiserID = 12345))

DECLARE @sp_Date DATETIME
SET @sp_Date = '2009-10-29 13:13:07.440'

SELECT DISTINCT pat.PublicationID
FROM PubAdvTransData AS pat 
    INNER JOIN PubAdvertiser AS pa 
        ON pat.AdvTransID = pa.AdvTransID
WHERE (pat.LastAdDate > @sp_Date) AND (pa.AdvertiserID = 12345))

^wp.*\.php$ Should do the trick.

The .* means "any character, repeated 0 or more times". The next . is escaped because it's a special character, and you want a literal period (".php"). Don't forget that if you're typing this in as a literal string in something like C#, Java, etc., you need to escape the backslash because it's a special character in many literal strings.

This error is because print isn't a function in Python 2.6.

You can either define a helper UDF that performs the print, or use the __future__ library to treat print as a function:

>>> from operator import add
>>> f = sc.textFile("README.md")
>>> def g(x):
...     print x
...
>>> wc.foreach(g)

or

>>> from __future__ import print_function
>>> wc.foreach(print)

However, I think it would be better to use collect() to bring the RDD contents back to the driver, because foreach executes on the worker nodes and the outputs may not necessarily appear in your driver / shell (it probably will in local mode, but not when running on a cluster).

>>> for x in wc.collect():
...     print x

My fix for this was my child table needed to be populated before the parent table.

I had two tables: UserDetails and Login linked by an email address. I therefore had to insert into the UserDetails first before inserting into the Login table:

insert into UserDetails (Email, Name, Telephone, Department) values ('Email', 'Name', 'number', 'IT');

Then:

insert into Login (UserID, UserType, Email, Username, Password) VALUES (001, 'SYS-USR-ADMIN', 'Email', 'Name', 'Password')

First of all this code snippet

char *addr=NULL;
strcpy(addr,retstring().c_str());

is invalid because you did not allocate memory where you are going to copy retstring().c_str().

As for the error message then it is clear enough. The type of expression data.str().c_str() is const char * but the third parameter of the function is declared as char *. You may not assign an object of type const char * to an object of type char *. Either the function should define the third parameter as const char * if it does not change the object pointed by the third parameter or you may not pass argument of type const char *.

Try wrapping the spans in an anchor tag and apply the background image to that.

java.time.Instant

Just use Instant of java.time.

    System.out.println(Instant.now());

This just printed:

2018-01-27T09:35:23.179612Z

Instant.toString always gives UTC time.

The output is usually sortable, but there are unfortunate exceptions. toString gives you enough groups of three decimals to render the precision it holds. On the Java 9 on my Mac the precision of Instant.now() seems to be microseconds, but we should expect that in approximately one case out of a thousand it will hit a whole number of milliseconds and print only three decimals. Strings with unequal numbers of decimals will be sorted in the wrong order (unless you write a custom comparator to take this into account).

Instant is one of the classes in java.time, the modern Java date and time API, which I warmly recommend that you use instead of the outdated Date class. java.time is built into Java 8 and later and has also been backported to Java 6 and 7.

Checking for nothing/Null is the way to do it.

Dealing with object types is not the way to go. Declare a strict type and try to cast the object to the correct type. (And use cast hint or Convert)

 private const string SESSION_VAR = "myString";
 string sSession;
 if (Session[SESSION_VAR] != null)
 {
     sSession = (string)Session[SESSION_VAR];
 }
 else
 {
     sSession = "set this";
     Session[SESSION_VAR] = sSession;
 }

Simply use the Body Tab and enter the post parameters there. Note that Body Tab is disabled if Get is selected.

If your database has compatibility level of 130 or higher then you can use the STRING_SPLIT function along with OFFSET FETCH clauses to get the specific item by index.

To get the item at index N (zero based), you can use the following code

SELECT value
FROM STRING_SPLIT('Hello John Smith',' ')
ORDER BY (SELECT NULL)
OFFSET N ROWS
FETCH NEXT 1 ROWS ONLY

To check the compatibility level of your database, execute this code:

SELECT compatibility_level  
FROM sys.databases WHERE name = 'YourDBName';

In design mode (right click table select modify) highlight both columns right click and choose set primary key

In my case, I added my libraries to Modulepath instead on Classpath.

It only works if JUnit is correctly added to Classpath.

A simple answer without any regex would be:

str = str.substr(0, str.lastIndexOf(list[i])) + 'finish'

If you want to search on both FROM and TO airports, you'll want to join on the Airports table twice - then you can use both from and to tables in your results set:

SELECT
   Flights.*,fromAirports.*,toAirports.*
FROM
   Flights
INNER JOIN 
   Airports fromAirports on Flights.fairport = fromAirports.code
INNER JOIN 
   Airports toAirports on Flights.tairport = toAirports.code
WHERE
 ...

Try this:

in.nextLine();

This advances the Scanner to the next line.

I ran into a similar problem while plotting a grid of graphs. The graphs consisted of two parts (top and bottom). The y-label was supposed to be centered over both parts.

I did not want to use a solution that depends on knowing the position in the outer figure (like fig.text()), so I manipulated the y-position of the set_ylabel() function. It is usually 0.5, the middle of the plot it is added to. As the padding between the parts (hspace) in my code was zero, I could calculate the middle of the two parts relative to the upper part.

import matplotlib.pyplot as plt
import matplotlib.gridspec as gridspec

# Create outer and inner grid
outerGrid = gridspec.GridSpec(2, 3, width_ratios=[1,1,1], height_ratios=[1,1])
somePlot = gridspec.GridSpecFromSubplotSpec(2, 1,
               subplot_spec=outerGrid[3], height_ratios=[1,3], hspace = 0)

# Add two partial plots
partA = plt.subplot(somePlot[0])
partB = plt.subplot(somePlot[1])

# No x-ticks for the upper plot
plt.setp(partA.get_xticklabels(), visible=False)

# The center is (height(top)-height(bottom))/(2*height(top))
# Simplified to 0.5 - height(bottom)/(2*height(top))
mid = 0.5-somePlot.get_height_ratios()[1]/(2.*somePlot.get_height_ratios()[0])
# Place the y-label
partA.set_ylabel('shared label', y = mid)

plt.show()

picture

Downsides:

• The horizontal distance to the plot is based on the top part, the bottom ticks might extend into the label.

• The formula does not take space between the parts into account.

• Throws an exception when the height of the top part is 0.

There is probably a general solution that takes padding between figures into account.

Following is another version that does the same thing (and handle nested properties), which I think is simpler (no dependencies on external libraries and can be modified easily to do things other than logging):

public class ObjectDumper
{
    public static string Dump(object obj)
    {
        return new ObjectDumper().DumpObject(obj);
    }

    StringBuilder _dumpBuilder = new StringBuilder();

    string DumpObject(object obj)
    {
        DumpObject(obj, 0);
        return _dumpBuilder.ToString();
    }

    void DumpObject(object obj, int nestingLevel = 0)
    {
        var nestingSpaces = "".PadLeft(nestingLevel * 4);

        if (obj == null)
        {
            _dumpBuilder.AppendFormat("{0}null\n", nestingSpaces);
        }
        else if (obj is string || obj.GetType().IsPrimitive)
        {
            _dumpBuilder.AppendFormat("{0}{1}\n", nestingSpaces, obj);
        }
        else if (ImplementsDictionary(obj.GetType()))
        {
            using (var e = ((dynamic)obj).GetEnumerator())
            {
                var enumerator = (IEnumerator)e;
                while (enumerator.MoveNext())
                {
                    dynamic p = enumerator.Current;

                    var key = p.Key;
                    var value = p.Value;
                    _dumpBuilder.AppendFormat("{0}{1} ({2})\n", nestingSpaces, key, value != null ? value.GetType().ToString() : "<null>");
                    DumpObject(value, nestingLevel + 1);
                }
            }
        }
        else if (obj is IEnumerable)
        {
            foreach (dynamic p in obj as IEnumerable)
            {
                DumpObject(p, nestingLevel);
            }
        }
        else
        {
            foreach (PropertyDescriptor descriptor in TypeDescriptor.GetProperties(obj))
            {
                string name = descriptor.Name;
                object value = descriptor.GetValue(obj);

                _dumpBuilder.AppendFormat("{0}{1} ({2})\n", nestingSpaces, name, value != null ? value.GetType().ToString() : "<null>");
                DumpObject(value, nestingLevel + 1);
            }
        }
    }

    bool ImplementsDictionary(Type t)
    {
        return t.GetInterfaces().Any(i => i.Name.Contains("IDictionary"));
    }
}

Well, once you have your font, you can invoke deriveFont. For example,

helvetica = helvetica.deriveFont(Font.BOLD, 12f);

Changes the font's style to bold and its size to 12 points.

Alternatively, you can just use position:absolute:

#content
{
    position:absolute;
    top: 111px;
    bottom: 0px;
}

However, IE6 doesn't like top and bottom declarations. But web developers don't like IE6.

Example: index = False

import pandas as pd

writer = pd.ExcelWriter("dataframe.xlsx", engine='xlsxwriter')
dataframe.to_excel(writer,sheet_name = dataframe, index=False)
writer.save() 

How do I rename a specific column in pandas?

From v0.24+, to rename one (or more) columns at a time,

• DataFrame.rename() with axis=1 or axis='columns' (the axis argument was introduced in v0.21.

• Index.str.replace() for string/regex based replacement.

If you need to rename ALL columns at once,

• DataFrame.set_axis() method with axis=1. Pass a list-like sequence. Options are available for in-place modification as well.

rename with axis=1

df = pd.DataFrame('x', columns=['y', 'gdp', 'cap'], index=range(5))
df

   y gdp cap
0  x   x   x
1  x   x   x
2  x   x   x
3  x   x   x
4  x   x   x

With 0.21+, you can now specify an axis parameter with rename:

df.rename({'gdp':'log(gdp)'}, axis=1)
# df.rename({'gdp':'log(gdp)'}, axis='columns')
    
   y log(gdp) cap
0  x        x   x
1  x        x   x
2  x        x   x
3  x        x   x
4  x        x   x

(Note that rename is not in-place by default, so you will need to assign the result back.)

This addition has been made to improve consistency with the rest of the API. The new axis argument is analogous to the columns parameter—they do the same thing.

df.rename(columns={'gdp': 'log(gdp)'})

   y log(gdp) cap
0  x        x   x
1  x        x   x
2  x        x   x
3  x        x   x
4  x        x   x

rename also accepts a callback that is called once for each column.

df.rename(lambda x: x[0], axis=1)
# df.rename(lambda x: x[0], axis='columns')

   y  g  c
0  x  x  x
1  x  x  x
2  x  x  x
3  x  x  x
4  x  x  x

For this specific scenario, you would want to use

df.rename(lambda x: 'log(gdp)' if x == 'gdp' else x, axis=1)

Index.str.replace

Similar to replace method of strings in python, pandas Index and Series (object dtype only) define a ("vectorized") str.replace method for string and regex-based replacement.

df.columns = df.columns.str.replace('gdp', 'log(gdp)')
df
 
   y log(gdp) cap
0  x        x   x
1  x        x   x
2  x        x   x
3  x        x   x
4  x        x   x

The advantage of this over the other methods is that str.replace supports regex (enabled by default). See the docs for more information.

Passing a list to set_axis with axis=1

Call set_axis with a list of header(s). The list must be equal in length to the columns/index size. set_axis mutates the original DataFrame by default, but you can specify inplace=False to return a modified copy.

df.set_axis(['cap', 'log(gdp)', 'y'], axis=1, inplace=False)
# df.set_axis(['cap', 'log(gdp)', 'y'], axis='columns', inplace=False)

  cap log(gdp)  y
0   x        x  x
1   x        x  x
2   x        x  x
3   x        x  x
4   x        x  x

Note: In future releases, inplace will default to True.

Method Chaining
Why choose set_axis when we already have an efficient way of assigning columns with df.columns = ...? As shown by Ted Petrou in this answer set_axis is useful when trying to chain methods.

Compare

# new for pandas 0.21+
df.some_method1()
  .some_method2()
  .set_axis()
  .some_method3()

Versus

# old way
df1 = df.some_method1()
        .some_method2()
df1.columns = columns
df1.some_method3()

The former is more natural and free flowing syntax.

I had faced the similar error when supporting one application. It was about the generated classes for a SOAP Webservice.

The issue was caused due to the missing classes. When javax.xml.bind.Marshaller was trying to marshal the jaxb object it was not finding all dependent classes which were generated by using wsdl and xsd. after adding the jar with all the classes at the class path the issue was resolved.

Current Working Directory

To get the current working directory, you can use:

process.cwd()

However, be aware that some scripts, notably gulp, will change the current working directory with process.chdir().

Node Module Path

You can get the path of the current module with:

• __filename
• __dirname

Original Directory (where the command was initiated)

If you are running a script from the command line, and you want the original directory from which the script was run, regardless of what directory the script is currently operating in, you can use:

process.env.INIT_CWD

Original directory, when working with NPM scripts

It's sometimes desirable to run an NPM script in the current directory, rather than the root of the project.

This variable is available inside npm package scripts as:

$INIT_CWD.

You must be running a recent version of NPM. If this variable is not available, make sure NPM is up to date.

This will allow you access the current path in your package.json, e.g.:

scripts: {
  "customScript": "gulp customScript --path $INIT_CWD"
}

function escapeRegExp(string) {
  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string
}

Example

escapeRegExp("All of these should be escaped: \ ^ $ * + ? . ( ) | { } [ ]");

>>> "All of these should be escaped: \\ \^ \$ \* \+ \? \. \( \) \| \{ \} \[ \] "

(NOTE: the above is not the original answer; it was edited to show the one from MDN. This means it does not match what you will find in the code in the below npm, and does not match what is shown in the below long answer. The comments are also now confusing. My recommendation: use the above, or get it from MDN, and ignore the rest of this answer. -Darren,Nov 2019)

npm install --save escape-string-regexp

See MDN: Javascript Guide: Regular Expressions

Other symbols (~`!@# ...) MAY be escaped without consequence, but are not required to be.

The Long Answer

If you're going to use the function above at least link to this stack overflow post in your code's documentation so that it doesn't look like crazy hard-to-test voodoo.

var escapeRegExp;

(function () {
  // Referring to the table here:
  // https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/regexp
  // these characters should be escaped
  // \ ^ $ * + ? . ( ) | { } [ ]
  // These characters only have special meaning inside of brackets
  // they do not need to be escaped, but they MAY be escaped
  // without any adverse effects (to the best of my knowledge and casual testing)
  // : ! , = 
  // my test "~!@#$%^&*(){}[]`/=?+\|-_;:'\",<.>".match(/[\#]/g)

  var specials = [
        // order matters for these
          "-"
        , "["
        , "]"
        // order doesn't matter for any of these
        , "/"
        , "{"
        , "}"
        , "("
        , ")"
        , "*"
        , "+"
        , "?"
        , "."
        , "\\"
        , "^"
        , "$"
        , "|"
      ]

      // I choose to escape every character with '\'
      // even though only some strictly require it when inside of []
    , regex = RegExp('[' + specials.join('\\') + ']', 'g')
    ;

  escapeRegExp = function (str) {
    return str.replace(regex, "\\$&");
  };

  // test escapeRegExp("/path/to/res?search=this.that")
}());

This console warning is not an error or an actual problem — Chrome is just spreading the word about this new standard to increase developer adoption.

It has nothing to do with your code. It is something their web servers will have to support.

Release date for a fix is February 4, 2020 per: https://www.chromium.org/updates/same-site

February, 2020: Enforcement rollout for Chrome 80 Stable: The SameSite-by-default and SameSite=None-requires-Secure behaviors will begin rolling out to Chrome 80 Stable for an initial limited population starting the week of February 17, 2020, excluding the US President’s Day holiday on Monday. We will be closely monitoring and evaluating ecosystem impact from this initial limited phase through gradually increasing rollouts.

I solved same problem by adding in response header

response.setHeader("Set-Cookie", "HttpOnly;Secure;SameSite=Strict");

SameSite prevents the browser from sending the cookie along with cross-site requests. The main goal is mitigating the risk of cross-origin information leakage. It also provides some protection against cross-site request forgery attacks. Possible values for the flag are Lax or Strict.

SameSite cookies explained here

Please refer this before applying any option.

Hope this helps you.

It's as easy as:

delete object.keyname;

or

delete object["keyname"];

Basically a vector is an array with automatic memory management. The data is contiguous in memory. Trying to insert data in the middle is a costly operation.

In a list the data is stored in unrelated memory locations. Inserting in the middle doesn't involve copying some of the data to make room for the new one.

To answer more specifically your question I'll quote this page

vectors are generally the most efficient in time for accessing elements and to add or remove elements from the end of the sequence. For operations that involve inserting or removing elements at positions other than the end, they perform worse than deques and lists, and have less consistent iterators and references than lists.

Here is my method for getting dates between two dates, including / w.o. including business days. It also takes source and desired date format as parameter.

public static List<String> getAllDatesBetweenTwoDates(String stdate,String enddate,String givenformat,String resultformat,boolean onlybunessdays) throws ParseException{
        DateFormat sdf;
        DateFormat sdf1;
        List<Date> dates = new ArrayList<Date>();
        List<String> dateList = new ArrayList<String>();
          SimpleDateFormat checkformat = new SimpleDateFormat(resultformat); 
          checkformat.applyPattern("EEE");  // to get Day of week
        try{
            sdf = new SimpleDateFormat(givenformat);
            sdf1 = new SimpleDateFormat(resultformat);
            stdate=sdf1.format(sdf.parse(stdate));
            enddate=sdf1.format(sdf.parse(enddate));

            Date  startDate = (Date)sdf1.parse( stdate); 
            Date  endDate = (Date)sdf1.parse( enddate);
            long interval = 24*1000 * 60 * 60; // 1 hour in millis
            long endTime =endDate.getTime() ; // create your endtime here, possibly using Calendar or Date
            long curTime = startDate.getTime();
            while (curTime <= endTime) {
                dates.add(new Date(curTime));
                curTime += interval;
            }
            for(int i=0;i<dates.size();i++){
                Date lDate =(Date)dates.get(i);
                String ds = sdf1.format(lDate);   
                if(onlybunessdays){
                    String day= checkformat.format(lDate); 
                    if(!day.equalsIgnoreCase("Sat") && !day.equalsIgnoreCase("Sun")){
                          dateList.add(ds);
                    }
                }else{
                      dateList.add(ds);
                }

                //System.out.println(" Date is ..." + ds);

            }


        }catch(ParseException e){
            e.printStackTrace();
            throw e;
        }finally{
            sdf=null;
            sdf1=null;
        }
        return dateList;
    }

And the method call would be like :

public static void main(String aregs[]) throws Exception {
        System.out.println(getAllDatesBetweenTwoDates("2015/09/27","2015/10/05","yyyy/MM/dd","dd-MM-yyyy",false));
    }

Actually you're close to your goal, you just need to use nodes() method to split your rows and then get values:

select
    s.SqmId,
    m.c.value('@id', 'varchar(max)') as id,
    m.c.value('@type', 'varchar(max)') as type,
    m.c.value('@unit', 'varchar(max)') as unit,
    m.c.value('@sum', 'varchar(max)') as [sum],
    m.c.value('@count', 'varchar(max)') as [count],
    m.c.value('@minValue', 'varchar(max)') as minValue,
    m.c.value('@maxValue', 'varchar(max)') as maxValue,
    m.c.value('.', 'nvarchar(max)') as Value,
    m.c.value('(text())[1]', 'nvarchar(max)') as Value2
from sqm as s
    outer apply s.data.nodes('Sqm/Metrics/Metric') as m(c)

When there is one commit only in the branch, I usually do

git merge branch_name --ff

Idk if you guys solved it but I recommend another way to do it, and it works :)

    ServiceUtil = ig.Class.extend({
        base_url : 'someurl',

        sendRequest: function(request)
        {
            var url = this.base_url + request;
            var requestVar = new XMLHttpRequest();
            dataGet = false;

            $.ajax({
                url: url,
                async: false,
                type: "get",
                success: function(data){
                    ServiceUtil.objDataReturned = data;
                }
            });
            return ServiceUtil.objDataReturned;                
        }
    })

So the main idea here is that, by adding async: false, then you make everything waits until the data is retrieved. Then you assign it to a static variable of the class, and everything magically works :)

Try this:

string[] a = new string[] { };

I did it using Angular 2 Location since I didn't want to manipulate the global window object myself.

https://angular.io/docs/ts/latest/api/common/index/Location-class.html#!#prepareExternalUrl-anchor

It can be done like this:

import {Component} from '@angular/core';
import {Location} from '@angular/common';
@Component({selector: 'app-component'})
class AppCmp {
  constructor(location: Location) {
    location.go('/foo');
  }
}

The answer above is correct. Please be sure that you have a string data in base64 in the data variable without any prefix or stuff like that just raw data.

Here's what I did on the server side (asp.net mvc core):

string path = Path.Combine(folder, fileName);
Byte[] bytes = System.IO.File.ReadAllBytes(path);
string base64 = Convert.ToBase64String(bytes);

On the client side, I did the following code:

const xhr = new XMLHttpRequest();

xhr.open("GET", url);
xhr.setRequestHeader("Content-Type", "text/plain");

xhr.onload = () => {
    var bin = atob(xhr.response);
    var ab = s2ab(bin); // from example above
    var blob = new Blob([ab], { type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;' });

    var link = document.createElement('a');
    link.href = window.URL.createObjectURL(blob);
    link.download = 'demo.xlsx';

    document.body.appendChild(link);

    link.click();

    document.body.removeChild(link);
};

xhr.send();

And it works perfectly for me.

To do it without any import:

>>> round_up = lambda num: int(num + 1) if int(num) != num else int(num)
>>> round_up(2.0)
2
>>> round_up(2.1)
3

If you are using hibernate, this error can be caused for keeping open a Session object more time than wait_timeout

I've documented a case in here for those who are interested.

The short answer is NO, PDO prepares will not defend you from all possible SQL-Injection attacks. For certain obscure edge-cases.

I'm adapting this answer to talk about PDO...

The long answer isn't so easy. It's based off an attack demonstrated here.

The Attack

So, let's start off by showing the attack...

$pdo->query('SET NAMES gbk');
$var = "\xbf\x27 OR 1=1 /*";
$query = 'SELECT * FROM test WHERE name = ? LIMIT 1';
$stmt = $pdo->prepare($query);
$stmt->execute(array($var));

In certain circumstances, that will return more than 1 row. Let's dissect what's going on here:

1. Selecting a Character Set

   $pdo->query('SET NAMES gbk');
   

   For this attack to work, we need the encoding that the server's expecting on the connection both to encode ' as in ASCII i.e. 0x27 and to have some character whose final byte is an ASCII \ i.e. 0x5c. As it turns out, there are 5 such encodings supported in MySQL 5.6 by default: big5, cp932, gb2312, gbk and sjis. We'll select gbk here.

   Now, it's very important to note the use of SET NAMES here. This sets the character set ON THE SERVER. There is another way of doing it, but we'll get there soon enough.

2. The Payload

   The payload we're going to use for this injection starts with the byte sequence 0xbf27. In gbk, that's an invalid multibyte character; in latin1, it's the string ¿'. Note that in latin1 and gbk, 0x27 on its own is a literal ' character.

   We have chosen this payload because, if we called addslashes() on it, we'd insert an ASCII \ i.e. 0x5c, before the ' character. So we'd wind up with 0xbf5c27, which in gbk is a two character sequence: 0xbf5c followed by 0x27. Or in other words, a valid character followed by an unescaped '. But we're not using addslashes(). So on to the next step...

3. $stmt->execute()

   The important thing to realize here is that PDO by default does NOT do true prepared statements. It emulates them (for MySQL). Therefore, PDO internally builds the query string, calling mysql_real_escape_string() (the MySQL C API function) on each bound string value.

   The C API call to mysql_real_escape_string() differs from addslashes() in that it knows the connection character set. So it can perform the escaping properly for the character set that the server is expecting. However, up to this point, the client thinks that we're still using latin1 for the connection, because we never told it otherwise. We did tell the server we're using gbk, but the client still thinks it's latin1.

   Therefore the call to mysql_real_escape_string() inserts the backslash, and we have a free hanging ' character in our "escaped" content! In fact, if we were to look at $var in the gbk character set, we'd see:

   ?' OR 1=1 /*

   Which is exactly what the attack requires.

4. The Query

   This part is just a formality, but here's the rendered query:

   SELECT * FROM test WHERE name = '?' OR 1=1 /*' LIMIT 1
   

Congratulations, you just successfully attacked a program using PDO Prepared Statements...

The Simple Fix

Now, it's worth noting that you can prevent this by disabling emulated prepared statements:

$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

This will usually result in a true prepared statement (i.e. the data being sent over in a separate packet from the query). However, be aware that PDO will silently fallback to emulating statements that MySQL can't prepare natively: those that it can are listed in the manual, but beware to select the appropriate server version).

The Correct Fix

The problem here is that we didn't call the C API's mysql_set_charset() instead of SET NAMES. If we did, we'd be fine provided we are using a MySQL release since 2006.

If you're using an earlier MySQL release, then a bug in mysql_real_escape_string() meant that invalid multibyte characters such as those in our payload were treated as single bytes for escaping purposes even if the client had been correctly informed of the connection encoding and so this attack would still succeed. The bug was fixed in MySQL 4.1.20, 5.0.22 and 5.1.11.

But the worst part is that PDO didn't expose the C API for mysql_set_charset() until 5.3.6, so in prior versions it cannot prevent this attack for every possible command! It's now exposed as a DSN parameter, which should be used instead of SET NAMES...

The Saving Grace

As we said at the outset, for this attack to work the database connection must be encoded using a vulnerable character set. utf8mb4 is not vulnerable and yet can support every Unicode character: so you could elect to use that instead—but it has only been available since MySQL 5.5.3. An alternative is utf8, which is also not vulnerable and can support the whole of the Unicode Basic Multilingual Plane.

Alternatively, you can enable the NO_BACKSLASH_ESCAPES SQL mode, which (amongst other things) alters the operation of mysql_real_escape_string(). With this mode enabled, 0x27 will be replaced with 0x2727 rather than 0x5c27 and thus the escaping process cannot create valid characters in any of the vulnerable encodings where they did not exist previously (i.e. 0xbf27 is still 0xbf27 etc.)—so the server will still reject the string as invalid. However, see @eggyal's answer for a different vulnerability that can arise from using this SQL mode (albeit not with PDO).

Safe Examples

The following examples are safe:

mysql_query('SET NAMES utf8');
$var = mysql_real_escape_string("\xbf\x27 OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

Because the server's expecting utf8...

mysql_set_charset('gbk');
$var = mysql_real_escape_string("\xbf\x27 OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

Because we've properly set the character set so the client and the server match.

$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$pdo->query('SET NAMES gbk');
$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));

Because we've turned off emulated prepared statements.

$pdo = new PDO('mysql:host=localhost;dbname=testdb;charset=gbk', $user, $password);
$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));

Because we've set the character set properly.

$mysqli->query('SET NAMES gbk');
$stmt = $mysqli->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$param = "\xbf\x27 OR 1=1 /*";
$stmt->bind_param('s', $param);
$stmt->execute();

Because MySQLi does true prepared statements all the time.

Wrapping Up

If you:

• Use Modern Versions of MySQL (late 5.1, all 5.5, 5.6, etc) AND PDO's DSN charset parameter (in PHP = 5.3.6)

OR

• Don't use a vulnerable character set for connection encoding (you only use utf8 / latin1 / ascii / etc)

OR

• Enable NO_BACKSLASH_ESCAPES SQL mode

You're 100% safe.

Otherwise, you're vulnerable even though you're using PDO Prepared Statements...

Addendum

I've been slowly working on a patch to change the default to not emulate prepares for a future version of PHP. The problem that I'm running into is that a LOT of tests break when I do that. One problem is that emulated prepares will only throw syntax errors on execute, but true prepares will throw errors on prepare. So that can cause issues (and is part of the reason tests are borking).

According to the new documentation, the link is now:

<a href="https://wa.me/?text=urlencodedtext">Share this</a>

If it doesn't work, try this one :

<a href="whatsapp://send?text=urlencodedtext">Share this</a>

Give the container class

.container{
    height: 100vh;
    width: 100vw;
    display: flex;
}

Give the div that's inside the container:

align-content: center;

All the content inside this div will show up in the middle of the page.

There's a whole page of the Django documentation devoted to this, well indexed from the contents page.

As that page states, you need to do:

my_obj.categories.add(fragmentCategory.objects.get(id=1))

or

my_obj.categories.create(name='val1')

Try calling setWillNotDraw(false) from surfaceCreated:

public void surfaceCreated(SurfaceHolder holder) {
    try {
        setWillNotDraw(false); 
        mycam.setPreviewDisplay(holder);
        mycam.startPreview();
    } catch (Exception e) {
        e.printStackTrace();
        Log.d(TAG,"Surface not created");
    }
}

@Override
protected void onDraw(Canvas canvas) {

    canvas.drawRect(area, rectanglePaint);
    Log.w(this.getClass().getName(), "On Draw Called");
}

and calling invalidate from onTouchEvent:

public boolean onTouch(View v, MotionEvent event) {

    invalidate();
    return true;
}

I use

patch -p1 --merge < patchfile

This way, conflicts may be resolved as usual.

Tip #2

Can't you use the classical 2> redirection operator.

(Get-PSSessionConfiguration -Name "MyShellUri" -ErrorAction SilentlyContinue) 2> $NULL
if(!$?){
   'foo'
}

I don't like errors so I avoid them at all costs.

try setting this

CATALINA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8 
-server -Xms1536m -Xmx1536m
-XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m 
-XX:MaxPermSize=256m -XX:+DisableExplicitGC"

in {$tomcat-folder}\bin\setenv.sh (create it if necessary).

See http://www.mkyong.com/tomcat/tomcat-javalangoutofmemoryerror-permgen-space/ for more details.

There's an easier way, have a link table, i.e.:

Table 1: clients, client info, blah blah blah

Table 2: courses, course info, blah blah

Table 3: clientid, courseid

Then do a JOIN and you're off to the races.

A web app can request access to a sandboxed file system by calling window.requestFileSystem(). Works in Chrome.

window.requestFileSystem = window.requestFileSystem || window.webkitRequestFileSystem;
var fs = null;

window.requestFileSystem(window.TEMPORARY, 1024 * 1024, function (filesystem) {
    fs = filesystem;
}, errorHandler);

fs.root.getFile('Hello.txt', {
    create: true
}, null, errorHandler);

function errorHandler(e) {
  var msg = '';

  switch (e.code) {
    case FileError.QUOTA_EXCEEDED_ERR:
      msg = 'QUOTA_EXCEEDED_ERR';
      break;
    case FileError.NOT_FOUND_ERR:
      msg = 'NOT_FOUND_ERR';
      break;
    case FileError.SECURITY_ERR:
      msg = 'SECURITY_ERR';
      break;
    case FileError.INVALID_MODIFICATION_ERR:
      msg = 'INVALID_MODIFICATION_ERR';
      break;
    case FileError.INVALID_STATE_ERR:
      msg = 'INVALID_STATE_ERR';
      break;
    default:
      msg = 'Unknown Error';
      break;
  };

  console.log('Error: ' + msg);
}

This is one of the other method to solve the Error: "Cannot get a text value from a numeric cell “Poi”"

Go to the Excel Sheet. Drag and Select the Numerics which you are importing Data from the Excel sheet. Go to Format > Number > Then Select "Plain Text" Then Export as .xlsx. Now Try to Run the Script

Hope works Fine...!

Cannot get a text value from a numeric cell “Poi”.img

I had same symptoms.

Please ensure you have the proper Visual Studio extension installed via Tools - Extensions and Updates. In my case, I had to install XUnit and Specflow from the Online option.

Then clean the solution and rebuild it.

If that still doesn't help, clear your temp directory (search for %temp% in the Start menu search and delete all contents in Temp)

And then finally try uninstalling Resharper which finally fixed my problem.

This is a simple tutorial on creating csv files using C# that you will be able to edit and expand on to fit your own needs.

First you’ll need to create a new Visual Studio C# console application, there are steps to follow to do this.

The example code will create a csv file called MyTest.csv in the location you specify. The contents of the file should be 3 named columns with text in the first 3 rows.

https://tidbytez.com/2018/02/06/how-to-create-a-csv-file-with-c/

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.IO;

namespace CreateCsv
{
    class Program
    {
        static void Main()
        {
            // Set the path and filename variable "path", filename being MyTest.csv in this example.
            // Change SomeGuy for your username.
            string path = @"C:\Users\SomeGuy\Desktop\MyTest.csv";

            // Set the variable "delimiter" to ", ".
            string delimiter = ", ";

            // This text is added only once to the file.
            if (!File.Exists(path))
            {
                // Create a file to write to.
                string createText = "Column 1 Name" + delimiter + "Column 2 Name" + delimiter + "Column 3 Name" + delimiter + Environment.NewLine;
                File.WriteAllText(path, createText);
            }

            // This text is always added, making the file longer over time
            // if it is not deleted.
            string appendText = "This is text for Column 1" + delimiter + "This is text for Column 2" + delimiter + "This is text for Column 3" + delimiter + Environment.NewLine;
            File.AppendAllText(path, appendText);

            // Open the file to read from.
            string readText = File.ReadAllText(path);
            Console.WriteLine(readText);
        }
    }
}

I haven't managed to get WMDC working on Windows 10 (it hanged on splash screen upon start), so I've finally uninstalled it. But now I have a Portable Devices / Compact device in the Device Manager and I can browse my Windows Compact 7 device within Windows Explorer. All my apps using RAPI also work. Maybe this is the result of installing/uninstalling WMDC, or probably this functionality was already presented on Windows 10 and I've just overlooked it initially.

I tried some of the sources online and finally, the below selection works fine for me (Dreamweaver on Mac). For versions above Adobe Dreamweaver CC 2017 and above:

Adobe says:

Edit > Code > Apply Source Formatting

Moreover, full documentation with other supporting information for tasks such as setting defaults, etc. on https://helpx.adobe.com/dreamweaver/using/format-code.html.

Other answers still won't work when the name of your directory does not correspond to remote repository name (and it could). You can get the real name of the repository with something like this:

git remote show origin -n | grep "Fetch URL:" | sed -E "s#^.*/(.*)$#\1#" | sed "s#.git$##"

Basically, you call git remote show origin, take the repository URL from "Fetch URL:" field, and regex it to get the portion with name: https://github.com/dragn/neat-vimrc.git

You could try Directory.Exists(path) and Directory.GetFiles(path) - probably less overhead (no objects - just strings etc).

You can do the following, when your current directory is parent_directory:

for d in [0-9][0-9][0-9]
do
    ( cd "$d" && your-command-here )
done

The ( and ) create a subshell, so the current directory isn't changed in the main script.

As per your question requirement , I would like to suggest that Map will solve your problem very efficient and without any hassle.

In Map you can give the name as key and your original object as value.

  Map<String,Cave> myMap=new HashMap<String,Cave>();

1. In my case I just close the app form emulator

2. Then run this again

react-native run-android

Step1: Delete all instances of java from you machine

Step2: Delete all the environment variables related to java/jdk/jre

Step3: Check in programm files and program files(X86) folder, there should not be java folder.

Step4: Install java again.

Step5: Go to cmd and type "java -version" Result: it will display the java version which is installed in your machine.

Step6: now delete all the files which are in C:/User/AdminOrUserNameofYourMachine/.m2 folder

Step6: go to cmd and run "mvn -v" Result: It will display the Apache maven version installed on your machine

Step7: Now Rebuild your project.

This worked for me.

This simple method solved the problem for me: Copy the content of your dataset, open an empty Excel sheet, choose "Paste Special" -> "Values", and save. Import the new file instead.

(I tried all the existing solutions, and none worked for me. My old dataset appeared to have no missing values, space, special characters, or embedded formulas.)

You can do this by changing the gradle file.

 build.gradle > change

    classpath 'com.android.tools.build:gradle:3.0.1'
    }
    gradle-wrapper.properties > update

It means not equal to

Should I use != or <> for not equal in TSQL?

Have a look at the link. It has detailed explanation of what to use for what.

If you want to load a test resource file as a string with just few lines of code and without any extra dependencies, this does the trick:

public String loadResourceAsString(String fileName) throws IOException {
    Scanner scanner = new Scanner(getClass().getClassLoader().getResourceAsStream(fileName));
    String contents = scanner.useDelimiter("\\A").next();
    scanner.close();
    return contents;
}

"\\A" matches the start of input and there's only ever one. So this parses the entire file contents and returns it as a string. Best of all, it doesn't require any 3rd party libraries (like IOUTils).

indeed, all of these datetime types can be difficult, and potentially problematic (must keep careful track of timezone information). here's what i have done, though i admit that i am concerned that at least part of it is "not by design". also, this can be made a bit more compact as needed. starting with a numpy.datetime64 dt_a:

dt_a

numpy.datetime64('2015-04-24T23:11:26.270000-0700')

dt_a1 = dt_a.tolist() # yields a datetime object in UTC, but without tzinfo

dt_a1

datetime.datetime(2015, 4, 25, 6, 11, 26, 270000)

# now, make your "aware" datetime:

dt_a2=datetime.datetime(*list(dt_a1.timetuple()[:6]) + [dt_a1.microsecond], tzinfo=pytz.timezone('UTC'))

... and of course, that can be compressed into one line as needed.

In my situation, in order to include color.sh from the same directory in init.sh, I had to do something as follows.

. ./color.sh

Not sure why the ./ and not color.sh directly. The content of color.sh is as follows.

RED=`tput setaf 1`
GREEN=`tput setaf 2`
BLUE=`tput setaf 4`
BOLD=`tput bold`
RESET=`tput sgr0`

Making use of File color.sh does not error but, the color do not display. I have tested this in Ubuntu 18.04 and the Bash version is:

GNU bash, version 4.4.19(1)-release (x86_64-pc-linux-gnu)

if you did change the httpd.conf file located under conf_files folder, don't use windows notepad, you need a unix text editor, try TED pad, after making any changes to your httpd.conf file save it. ps: if you use a dos/windows editor you will end up with an "Error in Apache file changed" message. so do be careful....

If you don't want to deal with interactive mode then do this:

Update your last pushed commit

git commit --amend -m "New commit message."

Push your new commit message (this will replace the old last commit message to this new one)

git push origin --force **branch-name**

Execution of many functions through an ES6 callback

const f = (funs) => {_x000D_
  funs().forEach((fun) => fun)_x000D_
}_x000D_
_x000D_
f(() => [_x000D_
  console.log(1),_x000D_
  console.log(2),_x000D_
  console.log(3)_x000D_
])

You can modify the formData by catching the 'sending' event from your dropzone.

dropZone.on('sending', function(data, xhr, formData){
        formData.append('fieldname', 'value');
});

To just get the size of the directory, nothing more:

du --max-depth=0 ./directory

output looks like

5234232       ./directory

-ErrorAction Stop is changing things for you. Try adding this and see what you get:

Catch [System.Management.Automation.ActionPreferenceStopException] {
"caught a StopExecution Exception" 
$error[0]
}

Here's my solution to the problem using MooTools which works in Firefox 3.6, Safari 4.0.4 and Internet Explorer 7:

var iframe_container = $('iframe_container_id');
var iframe_style = {
    height: 300,
    width: '100%'
};
if (!Browser.Engine.trident) {
    // IE has hasLayout issues if iframe display is none, so don't use the loading class
    iframe_container.addClass('loading');
    iframe_style.display = 'none';
}
this.iframe = new IFrame({
    frameBorder: 0,
    src: "http://www.youriframeurl.com/",
    styles: iframe_style,
    events: {
        'load': function() {
            var innerDoc = (this.contentDocument) ? this.contentDocument : this.contentWindow.document;
            var h = this.measure(function(){
                return innerDoc.body.scrollHeight;
            });            
            this.setStyles({
                height: h.toInt(),
                display: 'block'
            });
            if (!Browser.Engine.trident) {
                iframe_container.removeClass('loading');
            }
        }
    }
}).inject(iframe_container);

Style the "loading" class to show an Ajax loading graphic in the middle of the iframe container. Then for browsers other than Internet Explorer, it will display the full height IFRAME once the loading of its content is complete and remove the loading graphic.

From Wikipedia Media type,

A media type is composed of a type, a subtype, and optional parameters. As an example, an HTML file might be designated text/html; charset=UTF-8.

Media type consists of top-level type name and sub-type name, which is further structured into so-called "trees".

top-level type name / subtype name [ ; parameters ]

top-level type name / [ tree. ] subtype name [ +suffix ] [ ; parameters ]

All media types should be registered using the IANA registration procedures. Currently the following trees are created: standard, vendor, personal or vanity, unregistered x.

Standard:

Media types in the standards tree do not use any tree facet (prefix).

type / media type name [+suffix]

Examples: "application/xhtml+xml", "image/png"

Vendor:

Vendor tree is used for media types associated with publicly available products. It uses vnd. facet.

type / vnd. media type name [+suffix] - used in the case of well-known producer

type / vnd. producer's name followed by media type name [+suffix] - producer's name must be approved by IANA

type / vnd. producer's name followed by product's name [+suffix] - producer's name must be approved by IANA

Personal or Vanity tree:

Personal or Vanity tree includes media types created experimentally or as part of products that are not distributed commercially. It uses prs. facet.

type / prs. media type name [+suffix]

Unregistered x. tree:

The "x." tree may be used for media types intended exclusively for use in private, local environments and only with the active agreement of the parties exchanging them. Types in this tree cannot be registered.

According to the previous version of RFC 6838 - obsoleted RFC 2048 (published in November 1996) it should rarely, if ever, be necessary to use unregistered experimental types, and as such use of both "x-" and "x." forms is discouraged. Previous versions of that RFC - RFC 1590 and RFC 1521 stated that the use of "x-" notation for the sub-type name may be used for unregistered and private sub-types, but this recommendation was obsoleted in November 1996.

type / x. media type name [+suffix]

So its clear that the standard type MIME type application/pdf is the appropriate one to use while you should avoid using the obsolete and unregistered x- media type as stated in RFC 2048 and RFC 6838.

You can use the stringr library:

library('stringr')

a <- runif(10)
b <- letters[1:10]
c <- c(rep('A-B', 4), rep('A_B', 6))
data <- data.frame(a, b, c)

data

#             a b   c
# 1  0.19426707 a A-B
# 2  0.12902673 b A-B
# 3  0.78324955 c A-B
# 4  0.06469028 d A-B
# 5  0.34752264 e A_C
# 6  0.55313288 f A_C
# 7  0.31264280 g A_C
# 8  0.33759921 h A_C
# 9  0.72322599 i A_C
# 10 0.25223075 j A_C

data$c <- str_replace_all(data$c, '_', '-')

data

#             a b   c
# 1  0.19426707 a A-B
# 2  0.12902673 b A-B
# 3  0.78324955 c A-B
# 4  0.06469028 d A-B
# 5  0.34752264 e A-C
# 6  0.55313288 f A-C
# 7  0.31264280 g A-C
# 8  0.33759921 h A-C
# 9  0.72322599 i A-C
# 10 0.25223075 j A-C

Note that this does change factored variables into character.

Yes.
Code must be compiled with Java 8 compliant compiler with option to store formal parameter names turned on (-parameters option).
Then this code snippet should work:

Class<String> clz = String.class;
for (Method m : clz.getDeclaredMethods()) {
   System.err.println(m.getName());
   for (Parameter p : m.getParameters()) {
    System.err.println("  " + p.getName());
   }
}
