net use \\<host> /delete should work, but many times it does not.

net stop workstation as @DaveInCaz offered works in such cases.

I have some why and hows I couldn't fit into a comment.

• It's not enough to restart the Workstation service (e.g. from services.msc console)
  The service probably needs to be disabled for some short period of time. If you do this restart from a script, might be better to add a 1 second delay.

• In cases when net use \\<host> /delete does not work because another program is still using that share, you can identify such program and remove the blocking handle without closing it. Use Sysinternals Process Explorer, press Ctrl+F for search and enter the name of host machine owning such share. Click on each result, program window behind search dialog jumps to found program's handle. Right click that handle and select Close Handle. (or just close such program if you can) This works only in regular cases where there really is a program blocking the share disconnect. Not in those weird cases when it's blocked for no reason.

• elevated account has it's own environment. This brings some unexpected behavior.
  If you do net use command in an elevated cmd/PS console, it will not affect which user will Windows Explorer use to access the share.
  And also other way around, if you run a program from the share and the program will ask and get elevated access, that program will loose connection to that share and any files it might need to run. You need to run net use from elevated cmd/PS to create an elevated share connection to that share.

• Removing Recent folders from Quick Access in Windows Explorer (top of left panel) might help in certain cases.
  If the Host you are connecting to offers different access levels based on user, and/or has a Guest user (anonymous) share access, this is a situation you might often run into.
  When you access a share using your username, folder inside such share might get assigned to Quick Access panel as a Recent item. When you open Windows Explorer after restart, Recent items inside Quick Access will be checked and a connection will be made to the Host machine and will stay open in form of a MUP. If your share accepts both authorized and anonymous connections, just opening Windows Explorer will create anonymous connection and when you click on a share which needs authorization, you will not get credential dialog but an error.

With PowerShell 5.1 in Windows 10 you can use:

Get-SmbMapping | Remove-SmbMapping -Confirm:$false

In Windows, if you have mapped network drives and you don't know the UNC path for them, you can start a command prompt (Start ? Run ? cmd.exe) and use the net use command to list your mapped drives and their UNC paths:

C:\>net use
New connections will be remembered.

Status       Local     Remote                    Network

-------------------------------------------------------------------------------
OK           Q:        \\server1\foo             Microsoft Windows Network
OK           X:        \\server2\bar             Microsoft Windows Network
The command completed successfully.

Note that this shows the list of mapped and connected network file shares for the user context the command is run under. If you run cmd.exe under your own user account, the results shown are the network file shares for yourself. If you run cmd.exe under another user account, such as the local Administrator, you will instead see the network file shares for that user.

You wan't to either change the user that the Service runs under from "System" or find a sneaky way to run your mapping as System.

The funny thing is that this is possible by using the "at" command, simply schedule your drive mapping one minute into the future and it will be run under the System account making the drive visible to your service.

$mylabel.text("-123456");
var string = $mylabel.text().replace('-', '');

if you have done it that way variable string now holds "123456"

you can also (i guess the better way) do this...

$mylabel.text("-123456");
$mylabel.text(function(i,v){
   return v.replace('-','');
});

Try the following :

try
{
    var fromEmailAddress =  ConfigurationManager.AppSettings["FromEmailAddress"].ToString();
    var fromEmailDisplayName = ConfigurationManager.AppSettings["FromEmailDisplayName"].ToString();
    var fromEmailPassword = ConfigurationManager.AppSettings["FromEmailPassword"].ToString();
    var smtpHost = ConfigurationManager.AppSettings["SMTPHost"].ToString();
    var smtpPort = ConfigurationManager.AppSettings["SMTPPort"].ToString();

    string body = "Your registration has been done successfully. Thank you.";
    MailMessage message = new MailMessage(new MailAddress(fromEmailAddress, fromEmailDisplayName), new MailAddress(ud.LoginId, ud.FullName));
    message.Subject = "Thank You For Your Registration";
    message.IsBodyHtml = true;
    message.Body = body;

    var client = new SmtpClient();
    client.Credentials = new NetworkCredential(fromEmailAddress, fromEmailPassword);
    client.Host = smtpHost;
    client.EnableSsl = true;
    client.Port = !string.IsNullOrEmpty(smtpPort) ? Convert.ToInt32(smtpPort) : 0;
    client.Send(message);
}
catch (Exception ex)
{
    throw (new Exception("Mail send failed to loginId " + ud.LoginId + ", though registration done."));
}

And then in you web.config add the following in between

<!--Email Config-->
<add key="FromEmailAddress" value="sender emailaddress"/>
<add key="FromEmailDisplayName" value="Display Name"/>
<add key="FromEmailPassword" value="sender Password"/>
<add key="SMTPHost" value="smtp-proxy.tm.net.my"/>
<add key="SMTPPort" value="smptp Port"/>

Summing up what the others have suggested, and adding a third way

You can:

• assign(**kwargs):

   df.assign(Name='abc')
  

• access the new column series (it will be created) and set it:

   df['Name'] = 'abc'
  

• insert(loc, column, value, allow_duplicates=False)

   df.insert(0, 'Name', 'abc')
  

where the argument loc ( 0 <= loc <= len(columns) ) allows you to insert the column where you want.

'loc' gives you the index that your column will be at after the insertion. For example, the code above inserts the column Name as the 0-th column, i.e. it will be inserted before the first column, becoming the new first column. (Indexing starts from 0).

All these methods allow you to add a new column from a Series as well (just substitute the 'abc' default argument above with the series).

LIMIT limit OFFSET offset will work.

But you need a stable ORDER BY clause, or the values may be ordered differently for the next call (after any write on the table for instance).

SELECT *
FROM   msgtable
WHERE  cdate = '2012-07-18'
ORDER  BY msgtable_id  -- or whatever is stable 
LIMIT  10
OFFSET 50;  -- to skip to page 6

Use standard-conforming date style (ISO 8601 in my example), which works irregardless of your locale settings.

Paging will still shift if involved rows are inserted or deleted or changed in relevant columns. It has to.

To avoid that shift or for better performance with big tables use smarter paging strategies:

• Optimize query with OFFSET on large table

You can also try:

...
var imageName = require('relative_path_of_image_from_component_file');
...
...

class XYZ extends Component {
    render(){
        return(
            ...
            <img src={imageName.default} alt="something"/>
            ...
        )
    }
}
...

Note: Make sure Image is not outside the project root folder.

you may check this equation i think it will help

SELECT id, ( 3959 * acos( cos( radians(37) ) * cos( radians( lat ) ) * cos( radians( lng ) - radians(-122) ) + sin( radians(37) ) * sin( radians( lat ) ) ) ) AS distance FROM markers HAVING distance < 25 ORDER BY distance LIMIT 0 , 20;

What you put inside the </dependencies> tag of the root pom will be included by all child modules of the root pom. If all your modules use that dependency, this is the way to go.

However, if only 3 out of 10 of your child modules use some dependency, you do not want this dependency to be included in all your child modules. In that case, you can just put the dependency inside the </dependencyManagement>. This will make sure that any child module that needs the dependency must declare it in their own pom file, but they will use the same version of that dependency as specified in your </dependencyManagement> tag.

You can also use the </dependencyManagement> to modify the version used in transitive dependencies, because the version declared in the upper most pom file is the one that will be used. This can be useful if your project A includes an external project B v1.0 that includes another external project C v1.0. Sometimes it happens that a security breach is found in project C v1.0 which is corrected in v1.1, but the developers of B are slow to update their project to use v1.1 of C. In that case, you can simply declare a dependency on C v1.1 in your project's root pom inside `, and everything will be good (assuming that B v1.0 will still be able to compile with C v1.1).

jQuery uses a .call(...) method to assign the current node to this inside the function you pass as the parameter.

EDIT:

Don't be afraid to look inside jQuery's code when you have a doubt, it's all in clear and well documented Javascript.

ie: the answer to this question is around line 574,
callback.call( object[ name ], name, object[ name ] ) === false

Doing this inline, I set the margin to 0 (ul style="margin:-0px"). The bullets align with paragraph with no overhang.

On a side note this is more efficient:

$(".menuItem").hover(function(){
    this.style.backgroundColor = "#F00";
}, function() {
    this.style.backgroundColor = "#000";
});

After trial and error I discovered that you need to stage the file that had the merge conflict, then you can commit the merge.

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

You could change your HTML to this:

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

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

#div1 .edit1

On in jQuery:

$("#div1 .edit1")

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

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

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

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

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

Running:

npm install

from inside your app directory (i.e. where package.json is located) will install the dependencies for your app, rather than install it as a module, as described here. These will be placed in ./node_modules relative to your package.json file (it's actually slightly more complex than this, so check the npm docs here).

You are free to move the node_modules dir to the parent dir of your app if you want, because node's 'require' mechanism understands this. However, if you want to update your app's dependencies with install/update, npm will not see the relocated 'node_modules' and will instead create a new dir, again relative to package.json.

To prevent this, just create a symlink to the relocated node_modules from your app dir:

ln -s ../node_modules node_modules

Some (speed) performance tests summarizing the various options, not that it really matters #microoptimization (using a linqpad extension)

Options

void Main()
{
    object objValue = null;
    test(objValue);
    string strValue = null;
    test(strValue);
}

// Define other methods and classes here
void test(string value) {
    new Perf<string> {
        { "coallesce", n => (value ?? string.Empty).ToString() },
        { "nullcheck", n => value == null ? string.Empty : value.ToString() },
        { "str.Format", n => string.Format("{0}", value) },
        { "str.Concat", n => string.Concat(value) },
        { "string +", n => "" + value },
        { "Convert", n => Convert.ToString(value) },
    }.Vs();
}

void test(object value) {
    new Perf<string> {
        { "coallesce", n => (value ?? string.Empty).ToString() },
        { "nullcheck", n => value == null ? string.Empty : value.ToString() },
        { "str.Format", n => string.Format("{0}", value) },
        { "str.Concat", n => string.Concat(value) },
        { "string +", n => "" + value },
        { "Convert", n => Convert.ToString(value) },
    }.Vs();
}

Probably important to point out that Convert.ToString(...) will retain a null string.

Since my requirement is override the existing textView get from findViewById(getResources().getIdentifier("xxx", "id", "android"));, so I can't simply try onDraw() of other answer.

But I just figure out the correct steps to fixed my problem, here is the final result from Layout Inspector:

Since what I wanted is merely remove the top spaces, so I don't have to choose other font to remove bottom spaces.

Here is the critical code to fixed it:

Typeface mfont = Typeface.createFromAsset(getResources().getAssets(), "fonts/myCustomFont.otf");
myTextView.setTypeface(mfont);

myTextView.setPadding(0, 0, 0, 0);

myTextView.setIncludeFontPadding(false);

The first key is set custom font "fonts/myCustomFont.otf" which has the space on bottom but not on the top, you can easily figure out this by open otf file and click any font in android Studio:

As you can see, the cursor on the bottom has extra spacing but not on the top, so it fixed my problem.

The second key is you can't simply skip any of the code, otherwise it might not works. That's the reason you can found some people comment that an answer is working and some other people comment that it's not working.

Let's illustrated what will happen if I remove one of them.

Without setTypeface(mfont);:

Without setPadding(0, 0, 0, 0);:

Without setIncludeFontPadding(false);:

Without 3 of them (i.e. the original):

no problem doing it with asp.... it's most natural to do so with MVC, but can be done with standard asp as well.

The MVC framework has all sorts of helper classes for JSON, if you can, I'd suggest sussing in some MVC-love, if not, you can probably easily just get the JSON helper classes used by MVC in and use them in the context of asp.net.

edit:

here's an example of how to return JSON data with MVC. This would be in your controller class. This is out of the box functionality with MVC--when you crate a new MVC project this stuff gets auto-created so it's nothing special. The only thing that I"m doing is returning an actionResult that is JSON. The JSON method I'm calling is a method on the Controller class. This is all very basic, default MVC stuff:

public ActionResult GetData()
{
    var data = new { Name="kevin", Age=40 };
    return Json(data, JsonRequestBehavior.AllowGet);
}

This return data could be called via JQuery as an ajax call thusly:

$.get("/Reader/GetData/", function(data) { someJavacriptMethodOnData(data); });

It is a way to simplify error checking and avoid deep nested if's. For example:

do {
  // do something
  if (error) {
    break;
  }
  // do something else
  if (error) {
    break;
  }
  // etc..
} while (0);

SELECT * FROM ALL_OBJECTS WHERE OBJECT_TYPE IN ('FUNCTION','PROCEDURE','PACKAGE')

The column STATUS tells you whether the object is VALID or INVALID. If it is invalid, you have to try a recompile, ORACLE can't tell you if it will work before.

The next link will bring you to a great tutorial, that helped me a lot!

How to SQLITE in C#

I nearly used everything in that article to create the SQLite database for my own C# Application.

Don't forget to download the SQLite.dll, and add it as a reference to your project. This can be done using NuGet and by adding the dll manually.

After you added the reference, refer to the dll from your code using the following line on top of your class:

using System.Data.SQLite;

You can find the dll's here:

SQLite DLL's

You can find the NuGet way here:

NuGet

Up next is the create script. Creating a database file:

SQLiteConnection.CreateFile("MyDatabase.sqlite");

SQLiteConnection m_dbConnection = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");
m_dbConnection.Open();

string sql = "create table highscores (name varchar(20), score int)";

SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();

sql = "insert into highscores (name, score) values ('Me', 9001)";

command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();

m_dbConnection.Close();

After you created a create script in C#, I think you might want to add rollback transactions, it is safer and it will keep your database from failing, because the data will be committed at the end in one big piece as an atomic operation to the database and not in little pieces, where it could fail at 5th of 10 queries for example.

Example on how to use transactions:

 using (TransactionScope tran = new TransactionScope())
 {
     //Insert create script here.

     //Indicates that creating the SQLiteDatabase went succesfully, so the database can be committed.
     tran.Complete();
 }

It seems like these would be good to have because (I assume) if you could specify the number you're typing in is a short then java wouldn't have to cast it

Since the parsing of literals happens at compile time, this is absolutely irrelevant in regard to performance. The only reason having short and byte suffixes would be nice is that it lead to more compact code.

WKWebView: I find this question to be the best place to let people know that they should start using WKWebview as UIWebView is now deprecated.

Objective C

WKWebView *webView = [[WKWebView alloc] initWithFrame:self.view.frame];
webView.navigationDelegate = self;
NSURL *nsurl=[NSURL URLWithString:@"https://www.example.com/document.pdf"];
NSURLRequest *nsrequest=[NSURLRequest requestWithURL:nsurl];
[webView loadRequest:nsrequest];
[self.view addSubview:webView];

Swift

let myURLString = "https://www.example.com/document.pdf"
let url = NSURL(string: myURLString)
let request = NSURLRequest(URL: url!)  
let webView = WKWebView(frame: self.view.frame)
webView.navigationDelegate = self
webView.loadRequest(request)
view.addSubview(webView)

I haven't copied this code directly from Xcode, so it might, it might contain some syntax error. Please check while using it.

this is from Java API "sort

public static void sort(List list) Sorts the specified list into ascending order, according to the natural ordering of its elements. All elements in the list must implement the Comparable interface. Furthermore, all elements in the list must be mutually comparable (that is, e1.compareTo(e2) must not throw a ClassCastException for any elements e1 and e2 in the list)."

it has to do with implementing the Comparable interface

The subset command is not necessary. Just use data frame indexing

studentdata[studentdata$Drink == 'water',]

Read the warning from ?subset

This is a convenience function intended for use interactively. For programming it is better to use the standard subsetting functions like ‘[’, and in particular the non-standard evaluation of argument ‘subset’ can have unanticipated consequences.

Perhaps this is a bit off-topic, seeing as the question has already been answered, but I have experienced a similar problem. In my case only some of the unit test resources were copied to the output folder upon compilation. My persistence.xml in the META-INF folder got copied but nothing else.

In the end I "solved" the problem by renaming the problematic files, rebuiling the project and then changing the file names back to the original ones. Do not ask me why this worked but it did. My best guess is that, somehow, my IntelliJ project had gotten a bit out of sync with the file system and the renaming operation triggered some kind of internal "resource rescan".

I would use isset and empty:

session_start();
if(isset($_SESSION['blah']) && !empty($_SESSION['blah'])) {
   echo 'Set and not empty, and no undefined index error!';
}

array_key_exists is a nice alternative to using isset to check for keys:

session_start();
if(array_key_exists('blah',$_SESSION) && !empty($_SESSION['blah'])) {
    echo 'Set and not empty, and no undefined index error!';
}

Make sure you're calling session_start before reading from or writing to the session array.

You have three alternatives:

1. Use iFrame-resizer

This is a simple library for keeping iFrames sized to their content. It uses the PostMessage and MutationObserver APIs, with fall backs for IE8-10. It also has options for the content page to request the containing iFrame is a certain size and can also close the iFrame when your done with it.

https://github.com/davidjbradshaw/iframe-resizer

2. Use Easy XDM (PostMessage + Flash combo)

Easy XDM uses a collection of tricks for enabling cross-domain communication between different windows in a number of browsers, and there are examples for using it for iframe resizing:

http://easyxdm.net/wp/2010/03/17/resize-iframe-based-on-content/

http://kinsey.no/blog/index.php/2010/02/19/resizing-iframes-using-easyxdm/

Easy XDM works by using PostMessage on modern browsers and a Flash based solution as fallback for older browsers.

See also this thread on Stackoverflow (there are also others, this is a commonly asked question). Also, Facebook would seem to use a similar approach.

3. Communicate via a server

Another option would be to send the iframe height to your server and then poll from that server from the parent web page with JSONP (or use a long poll if possible).

declare @temp as varchar
  set @temp='Measure'
  if(@temp = 'Measure')
Select Measure from Measuretable
else
Select OtherMeasure from Measuretable

There are no JS callbacks for CSS assets.

Here is one solution that I would not recommend, but might be useful in some situations where modules were simply not generated:

import os
import sys
parent_dir_name = os.path.dirname(os.path.dirname(os.path.realpath(__file__)))
sys.path.append(parent_dir_name + "/your_dir")
import your_script
your_script.a_function()

git log origin/master..master

or, more generally:

git log <since>..<until>

You can use this with grep to check for a specific, known commit:

git log <since>..<until> | grep <commit-hash>

Or you can also use git-rev-list to search for a specific commit:

git rev-list origin/master | grep <commit-hash>

mysqladmin -u$USER -p$PASSWORD create $DB_NAME

Replace above variables and you are good to go with this oneliner. $USER is the username, $PASSWORD is the password and $DB_NAME is the name of the database.

i was looking for some string bits conversion and got here, If the next case is for you take //it so... if you want to use the bits from a string into different bits maybe this example would help

$string="1001"; //this would be 2^0*1+....0...+2^3*1=1+8=9
$bit4=$string[0];//1
$bit3=$string[1];
$bit2=$string[2];
$bit1=$string[3];//1

Following SierraX and Peter's suggestion about text manipulation, curly brackets {} are used to pass a variable to a command, for instance:

Let's say you have a sposi.txt file containing the first line of a well-known Italian novel:

> sposi="somewhere/myfolder/sposi.txt"
> cat $sposi

Ouput: quel ramo del lago di como che volge a mezzogiorno

Now create two variables:

# Search the 2nd word found in the file that "sposi" variable points to
> word=$(cat $sposi | cut -d " " -f 2)

# This variable will replace the word
> new_word="filone"

Now substitute the word variable content with the one of new_word, inside sposi.txt file

> sed -i "s/${word}/${new_word}/g" $sposi
> cat $sposi

Ouput: quel filone del lago di como che volge a mezzogiorno

The word "ramo" has been replaced.

 git reset HEAD@{4}

4 is changes before 4 steps ago. if you select a correct step, it should show the list of files that you removed from hard. then do:

$ git reflog show

it's going to show you local commit history we've already created. now do:

$ git reset --hard 8c4d112

8c4d112 is a code you want to reset your hard there. let's look at https://www.theserverside.com/video/How-to-use-the-git-reset-hard-command-to-change-a-commit-history to get more information.

Try this out: sudo cron reload It works for me on ubuntu 12.10

Whenever you wish to exit all open activities, you should press a button which loads the first Activity that runs when your application starts then clear all the other activities, then have the last remaining activity finish. to do so apply the following code in ur project

Intent intent = new Intent(getApplicationContext(), FirstActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("EXIT", true);
startActivity(intent);

The above code finishes all the activities except for FirstActivity. Then we need to finish the FirstActivity's Enter the below code in Firstactivity's oncreate

if (getIntent().getBooleanExtra("EXIT", false)) {
    finish();
}

and you are done....

Understanding legacy document modes

Use the following value to display the webpage in edge mode, which is the highest standards mode supported by Internet Explorer, from Internet Explorer 6 through IE11.

<meta http-equiv="x-ua-compatible" content="IE=edge"

Note that this is functionally equivalent to using the HTML5 doctype. It places Internet Explorer into the highest supported document mode. Edge most is most useful for regularly maintained websites that are routinely tested for interoperability between multiple browsers, including Internet Explorer.

Note Starting with IE11, edge mode is considered the preferred document mode. (In earlier versions, it was considered experimental.) To learn more, see Document modes are deprecated. Starting with Windows Internet Explorer 8, some web developers used the edge mode meta element to hide the Compatibility View button on the address bar. As of IE11, this is no longer necessary as the button has been removed from the address bar. Because it forces all pages to be opened in standards mode, regardless of the version of Internet Explorer, you might be tempted to use edge mode for all pages viewed with Internet Explorer. Don't do this, as the X-UA-Compatible header is only supported starting with Internet Explorer 8.

Tip If you want all supported versions of Internet Explorer to open your pages in standards mode, use the HTML5 document type declaration, as shown in the earlier example.

Also among the search results is:

• What does <meta http-equiv="X-UA-Compatible" content="IE=edge"> do?

Like @user293153 I only just discovered this question and it didn't seem to be answered correctly.

His answer was best. But you can also animate to the element as well.

$('html, body').animate({ scrollTop: $("#some_element").offset().top }, 500);

select min(sal) from emp where sal in 
    (select TOP 2 (sal) from emp order by sal desc)

Note

sal is col name
emp is table name

My Image name was 21.jpg. I renamed it as abc.jpg and it worked. So Make sure your image name not starting with a number. However all above answers are also accepted.

Query to join more than two tables:

SELECT ops.field_id, ops.option_id, ops.label
FROM engine4_user_fields_maps AS map 
JOIN engine4_user_fields_meta AS meta ON map.`child_id` = meta.field_id
JOIN engine4_user_fields_options AS ops ON map.child_id = ops.field_id 
WHERE map.option_id =39 AND meta.type LIKE 'outcomeresult' LIMIT 0 , 30

It supports lists, but not as a separate data structure (ignoring arrays for the moment).

The for loop iterates over a list (in the generic sense) of white-space separated values, regardless of how that list is created, whether literally:

for i in 1 2 3; do
    echo "$i"
done

or via parameter expansion:

listVar="1 2 3"
for i in $listVar; do
    echo "$i"
done

or command substitution:

for i in $(echo 1; echo 2; echo 3); do
    echo "$i"
done

An array is just a special parameter which can contain a more structured list of value, where each element can itself contain whitespace. Compare the difference:

array=("item 1" "item 2" "item 3")
for i in "${array[@]}"; do   # The quotes are necessary here
    echo "$i"
done

list='"item 1" "item 2" "item 3"'
for i in $list; do
    echo $i
done
for i in "$list"; do
    echo $i
done
for i in ${array[@]}; do
    echo $i
done

First you have to make sure the access level of the variable is protected or public. If the variable or property is private the page won't have access to it.

For me it was solved instantly by the following

1. Going to C:\xampp\apache\conf\extra
2. Editing inside the file httpd-xampp.conf
3. Edit the file as follows:

find the following lines by cont+f:

Alias /phpmyadmin "C:/xampp/phpMyAdmin/"
<Directory "C:/xampp/phpMyAdmin">
    AllowOverride AuthConfig
    Require local
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

only change local ----> all granted, so it becomes like this

Alias /phpmyadmin "C:/xampp/phpMyAdmin/"
<Directory "C:/xampp/phpMyAdmin">
    AllowOverride AuthConfig
    Require all granted
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</Directory>

After this the localhost will stop showing the error and will show admin panel. I found this solution in a video here: https://www.youtube.com/watch?v=MvYyEPaNNhE

As already mentioned, a device may support both mouse and touch input. Very often, the question is not "what is supported" but "what is currently used".

For this case, you can simply register mouse events (including the hover listener) and touch events alike.

element.addEventListener('touchstart',onTouchStartCallback,false);

element.addEventListener('onmousedown',onMouseDownCallback,false);

...

JavaScript should automatically call the correct listener based on user input. So, in case of a touch event, onTouchStartCallback will be fired, emulating your hover code.

Note that a touch may fire both kinds of listeners, touch and mouse. However, the touch listener goes first and can prevent subsequent mouse listeners from firing by calling event.preventDefault().

function onTouchStartCallback(ev) {
    // Call preventDefault() to prevent any further handling
    ev.preventDefault();
    your code...
}

It is possible. Make two functions: static and virtual

struct Object{     
  struct TypeInformation;
  static  const TypeInformation &GetTypeInformationStatic() const 
  { 
      return GetTypeInformationMain1();
  }
  virtual const TypeInformation &GetTypeInformation() const
  { 
      return GetTypeInformationMain1();
  }
protected:
  static const TypeInformation &GetTypeInformationMain1(); // Main function
};

struct SomeObject : public Object {     
  static  const TypeInformation &GetTypeInformationStatic() const 
  { 
      return GetTypeInformationMain2();
  }
  virtual const TypeInformation &GetTypeInformation() const
  { 
      return GetTypeInformationMain2();
  }
protected:
  static const TypeInformation &GetTypeInformationMain2(); // Main function
};

Another way is to use purrr package

# example data like what is said above

@A Handcart And Mohair

set.seed(1)
m <- data.frame(matrix(sample(100, 20, replace = TRUE), ncol = 4))


library(purrr)
means <- map_dbl(m, mean)

> means
#  X1   X2   X3   X4 
#47.0 64.4 44.8 67.8 

Thanks for all answers. You are all my heros ;-)

Did in the end something like this:

d = sorted(data, key = data.get)

for key in d:
    text = data[key]

You can use the VBA string functions (as @onedaywhen points out in the comments, they are not really the VBA functions, but their equivalents from the MS Jet libraries. As far as function signatures go, they are called and work the same, even though the actual presence of MS Access is not required for them to be available.):

SELECT DISTINCT Left(LastName, 1)
FROM Authors;

SELECT DISTINCT Mid(LastName, 1, 1)
FROM Authors;

Do a python -VV in the command line. It should return the version.

Based on icecrime's answer I wrote this function

std::vector<int> intToDigits(int num_)
{
    std::vector<int> ret;
    string iStr = to_string(num_);

    for (int i = iStr.size() - 1; i >= 0; --i)
    {
        int units = pow(10, i);
        int digit = num_ / units % 10;
        ret.push_back(digit);
    }   

    return ret;
}

I've had my drivers installed and the Arduino connected through an unpowered usb hub. Moving it to an USB port of my computer made it work.

The simple answer is to use the HttpRequest.UserHostAddress property.

Example: From within a Controller:

using System;
using System.Web.Mvc;

namespace Mvc.Controllers
{
    public class HomeController : ClientController
    {
        public ActionResult Index()
        {
            string ip = Request.UserHostAddress;

            ...
        }
    }
}

Example: From within a helper class:

using System.Web;

namespace Mvc.Helpers
{
    public static class HelperClass
    {
        public static string GetIPHelper()
        {
            string ip = HttpContext.Current.Request.UserHostAddress;
            ..
        }
    }
}

BUT, if the request has been passed on by one, or more, proxy servers then the IP address returned by HttpRequest.UserHostAddress property will be the IP address of the last proxy server that relayed the request.

Proxy servers MAY use the de facto standard of placing the client's IP address in the X-Forwarded-For HTTP header. Aside from there is no guarantee that a request has a X-Forwarded-For header, there is also no guarantee that the X-Forwarded-For hasn't been SPOOFED.

Original Answer

Request.UserHostAddress

The above code provides the Client's IP address without resorting to looking up a collection. The Request property is available within Controllers (or Views). Therefore instead of passing a Page class to your function you can pass a Request object to get the same result:

public static string getIPAddress(HttpRequestBase request)
{
    string szRemoteAddr = request.UserHostAddress;
    string szXForwardedFor = request.ServerVariables["X_FORWARDED_FOR"];
    string szIP = "";

    if (szXForwardedFor == null)
    {
        szIP = szRemoteAddr;
    }
    else
    {
        szIP = szXForwardedFor;
        if (szIP.IndexOf(",") > 0)
        {
            string [] arIPs = szIP.Split(',');

            foreach (string item in arIPs)
            {
                if (!isPrivateIP(item))
                {
                    return item;
                }
            }
        }
    }
    return szIP;
}

For mac users, I found this on the R for Mac FAQ

If you use a non-standard setup (e.g. different language than formats), you can override the auto-detection performed by setting `force.LANG' defaults setting, such as for example

 defaults write org.R-project.R force.LANG en_US.UTF-8 

when run in Terminal it will enforce US-english setting regardless of the system setting. If you don't know what Terminal is you can use this R command instead:

 system("defaults write org.R-project.R force.LANG en_US.UTF-8") 

but do not forget to quit R and start R.app again afterwards. Please note that you must always use `.UTF-8' version of the locale, otherwise R.app will not work properly.

This helped me to change my console language from Chinese to English.

You should seriously consider dhiller's answer:

1. Instead of worrying about adding your objects to a duplicate-less List, add them to a Set (any implementation), which will by nature filter out the duplicates.
2. When you need to call the method that requires a List, wrap it in a new ArrayList(set) (or a new LinkedList(set), whatever).

I think that the solution you posted with the NoDuplicatesList has some issues, mostly with the contains() method, plus your class does not handle checking for duplicates in the Collection passed to your addAll() method.

As you say, local variables and references are stored on the stack. When a method returns, the stack pointer is simply moved back to where it was before the method started, that is, all local data is "removed from the stack". Therefore, there is no garbage collection needed on the stack, that only happens in the heap.

To answer your specific questions:

• See this question on how to increase the stack size.
• You can limit the stack growth by:
  • grouping many local variables in an object: that object will be stored in the heap and only the reference is stored on the stack
  • limit the number of nested function calls (typically by not using recursion)
• For windows, the default stack size is 320k for 32bit and 1024k for 64bit, see this link.

The most correct and modern form is to use IoC to put dependencies into the endpoint method, like the thymeleaf Model instance...

 @Controller 
 public class GreetingController {
        @GetMapping("/greeting") 
        public String greeting(
            @RequestParam(name="name", required=false, defaultValue="World") String name, Model model) {
             model.addAttribute("name", name); 
             return "greeting"; 
             // returns the already proccessed model from src/main/resources/templates/greeting.html 
      }
 }

You have to retrieve it from the HOST header.

var host = req.get('host');

It is optional with HTTP 1.0, but required by 1.1. And, the app can always impose a requirement of its own.

If this is for supporting cross-origin requests, you would instead use the Origin header.

var origin = req.get('origin');

Note that some cross-origin requests require validation through a "preflight" request:

req.options('/route', function (req, res) {
    var origin = req.get('origin');
    // ...
});

If you're looking for the client's IP, you can retrieve that with:

var userIP = req.socket.remoteAddress;

• message.socket.
• socket.remoteAddress

Note that, if your server is behind a proxy, this will likely give you the proxy's IP. Whether you can get the user's IP depends on what info the proxy passes along. But, it'll typically be in the headers as well.

I use this code to remove my data but leave the formulas in the top row. It also removes all rows except for the top row and scrolls the page up to the top.

    ActiveSheet.ListObjects("TestTable").HeaderRowRange.Select
    'Remove the filters if one exists.
    If ActiveSheet.FilterMode Then
    Selection.AutoFilter
    End If
    'Clear all lines but the first one in the table leaving formulas for the next go round.
    With Worksheets("Data").ListObjects("TestTable")
    .Range.AutoFilter
    On Error Resume Next
    .DataBodyRange.Offset(1).Resize(.DataBodyRange.Rows.Count - 1, .DataBodyRange.Columns.Count).Rows.Delete

I had got the same error. Because of security reasons, I could not see option for allowing Apps downloaded from Anywhere in System preference-> Security Tab.

I removed the extended attribute from Zip file by below command.

xattr -d com.apple.quarantine [Zip file path] 

And then got below error:- org.eclipse.e4.core.di.InjectionException: java.lang.NoClassDefFoundError: javax/annotation/PostConstruct

Resolved it by uninstalling all different versions of java and installed just 1.8.0_231.

Worked finally.

Use these codes for 404 not found.

if(strstr($_SERVER['REQUEST_URI'],'index.php')){
  header('HTTP/1.0 404 Not Found');
  readfile('404missing.html');
  exit();
}

Here 404missing.html is your Not found design page. (it can be .html or .php)

You can either create a static method or use the other class as a member of your class calling the function in the constructor.

public class aClass {
      private SomeOtherClass oc;
      public class aClass( SomeOtherClass otherClass) {
         oc = otherClass;
      }

      public callOtherClassMethod() {
         oc.otherClassMethod();
       }
    }

Use strncpy

e.g.

strncpy(dest, src + beginIndex, endIndex - beginIndex);

This assumes you've

1. Validated that dest is large enough.
2. endIndex is greater than beginIndex
3. beginIndex is less than strlen(src)
4. endIndex is less than strlen(src)

You say it works once you install the VB6 IDE so the problem is likely to be that the components you are trying to use depend on the VB6 runtime being installed.

The VB6 runtime isn't installed on Windows by default.

Installing the IDE is one way to get the runtime. For non-developer machines, a "redistributable" installer package from Microsoft should be used instead.

Here is one VB6 runtime installer from Microsoft. I'm not sure if it will be the right version for your components:

Here is an ES6 function that will also work for objects with cyclic references:

function deepClone(obj, hash = new WeakMap()) {_x000D_
    if (Object(obj) !== obj) return obj; // primitives_x000D_
    if (hash.has(obj)) return hash.get(obj); // cyclic reference_x000D_
    const result = obj instanceof Set ? new Set(obj) // See note about this!_x000D_
                 : obj instanceof Map ? new Map(Array.from(obj, ([key, val]) => _x000D_

A note about Sets and Maps

How to deal with the keys of Sets and Maps is debatable: those keys are often primitives (in which case there is no debate), but they can also be objects. In that case the question becomes: should those keys be cloned?

One could argue that this should be done, so that if those objects are mutated in the copy, the objects in the original are not affected, and vice versa.

On the other hand one would want that if a Set/Map has a key, this should be true in both the original and the copy -- at least before any change is made to either of them. It would be strange if the copy would be a Set/Map that has keys that never occurred before (as they were created during the cloning process): surely that is not very useful for any code that needs to know whether a given object is a key in that Set/Map or not.

As you notice, I am more of the second opinion: the keys of Sets and Maps are values (maybe references) that should remain the same.

Such choices will often also surface with other (maybe custom) objects. There is no general solution, as much depends on how the cloned object is expected to behave in your specific case.

Try this https://ngrok.com/docs#expose

Just run ngrok 3000 , 3000 is the port number you want to expose to the internet. You can insert the port number which you want to expose, for rails its 3000. This will tunnel your localhost to the internet and you will be able to view your local host from anywhere

try

sudo chown mysql:mysql -R /var/lib/mysql

then start your mysql service

systemctl start mysqld

Well, you are having a valid access token to access your information and not others( this is because you got logged in and you have given permission to access your information). But the picture owner has not done the same (logged in + permission ) and so you are getting a violation error.

To obtain permission see this link and decide what kind of informations you want from any user and decide the permissions. Later on embed this in your code. (In the login function call)

Thanks

I solved this issue by redirecting the user to the FQDN of the server hosting the intranet.

IE probably uses the world's worst algorithm for detecting "intranet" sites ... indeed, specifying server.domain.tld solves the problem for me.

Yes, you read that correctly, IE detects intranet sites not by private IP address, like any dev who has heard of TCP/IP would do, no, by the "host" part of the URL, if it has no domain part, must be internal.

Scary to know the IE devs do not understand the most basic TCP/IP concepts.

Note that this was at a BIG enterprise customer, getting them to change GPO for you is like trying to move the Alps east by 4 meters, not gonna happen.

Your error appears when you have modified a file and the branch that you are switching to has changes for this file too (from latest merge point).

Your options, as I see it, are - commit, and then amend this commit with extra changes (you can modify commits in git, as long as they're not pushed); or - use stash:

git stash save your-file-name
git checkout master
# do whatever you had to do with master
git checkout staging
git stash pop

git stash save will create stash that contains your changes, but it isn't associated with any commit or even branch. git stash pop will apply latest stash entry to your current branch, restoring saved changes and removing it from stash.

In distributable software, I dont want my customers mucking about in the database by themselves. The program reads and writes it all by itself. The only reason for a user to touch the DB file is to take a backup copy. Therefore I have named it whatever_records.db

The simple .db extension tells the user that it is a binary data file and that's all they have to know. Calling it .sqlite invites the interested user to open it up and mess something up!

Totally depends on your usage scenario I suppose.

date("Y-m-d H:i:s"); // This should do it.

Why not just use the WordPress get_query_var() function? WordPress Code Reference

// Test if the query exists at the URL
if ( get_query_var('ppc') ) {

    // If so echo the value
    echo get_query_var('ppc');

}

Since get_query_var can only access query parameters available to WP_Query, in order to access a custom query var like 'ppc', you will also need to register this query variable within your plugin or functions.php by adding an action during initialization:

add_action('init','add_get_val');
function add_get_val() { 
    global $wp; 
    $wp->add_query_var('ppc'); 
}

Or by adding a hook to the query_vars filter:

function add_query_vars_filter( $vars ){
  $vars[] = "ppc";
  return $vars;
}
add_filter( 'query_vars', 'add_query_vars_filter' );

This question has already been marked answered, but I'd like to share some information that might help others with using FileList.

It would be convenient to treat a FileList as an array, but methods like sort, shift, pop, and slice don't work. As others have suggested, you can copy the FileList to an array. However, rather than using a loop, there's a simple one line solution to handle this conversion.

 // fileDialog.files is a FileList 

 var fileBuffer=[];

 // append the file list to an array
 Array.prototype.push.apply( fileBuffer, fileDialog.files ); // <-- here

 // And now you may manipulated the result as required

 // shift an item off the array
 var file = fileBuffer.shift(0,1);  // <-- works as expected
 console.info( file.name + ", " + file.size + ", " + file.type );

 // sort files by size
 fileBuffer.sort(function(a,b) {
    return a.size > b.size ? 1 : a.size < b.size ? -1 : 0;
 });

Tested OK in FF, Chrome, and IE10+

You can get just the edition name by using the following steps.

• Open "SQL Server Configuration Manager"
• From the List of SQL Server Services, Right Click on "SQL Server (Instance_name)" and Select Properties.
• Select "Advanced" Tab from the Properties window.
• Verify Edition Name from the "Stock Keeping Unit Name"
• Verify Edition Id from the "Stock Keeping Unit Id"
• Verify Service Pack from the "Service Pack Level"
• Verify Version from the "Version"

screen shot

Wrap the column name in brackets like so, from becomes [from].

select [from] from table;

It is also possible to use the following (useful when querying multiple tables):

select table.[from] from table;

s = 'sdsd'
print (s.upper())
upper = raw_input('type in something lowercase.')
lower = raw_input('type in the same thing caps lock.')
print upper.upper()
print lower.lower()

The original question is now more than 5 years old. In the meantime there is now a solution for a WinRT solution from ffmpeg and an integration sample from Microsoft.

Note that this problem usually occure for two reasons:

1-Port 80 is busy.

2-Port 443 is busy.

For number one as the others said, you can kill Skype and SQL Serever Reporter from

Windows Task Manager>"Services" Tab>"Services..." Button.

But if it dosen't worked, it's probably because of port 443, so try this one:

If you use VMware, go to

Windows Task Manager>"Services" Tab>"Services..." Button, and find "VMware Workstation Server" service, double click on it and press "Stop" button.

There is no need to stop other VMware's services.

Then again try to run Apache

System.err.println("Errorrrrrr") it will print text in Red color on console.

A slightly other way of iterating through each column of each line of a CSV-file would be

$path = "d:\scratch\export.csv"
$csv = Import-Csv -path $path

foreach($line in $csv)
{ 
    $properties = $line | Get-Member -MemberType Properties
    for($i=0; $i -lt $properties.Count;$i++)
    {
        $column = $properties[$i]
        $columnvalue = $line | Select -ExpandProperty $column.Name

        # doSomething $column.Name $columnvalue 
        # doSomething $i $columnvalue 
    }
} 

so you have the choice: you can use either $column.Name to get the name of the column, or $i to get the number of the column

Please do the import like below:

import { Router } from '@angular/Router';

The mistake that was being done was -> import { Router } from '@angular/router';

First, you should create an interval object from a range of dates. By the wording used in this sentence alone, one can easily identify basic abstractions needed. There is an interval as a concept, and a couple of more ways to implement it, include the one already mentioned -- from a range of dates. Thus, an interval looks like that:

$interval =
    new FromRange(
        new FromISO8601('2017-02-14T14:27:39+00:00'),
        new FromISO8601('2017-03-14T14:27:39+00:00')
    );

FromISO8601 has the same semantics: it's a datetime object created from iso8601-formatted string, hence the name.

When you have an interval, you can format it however you like. If you need a number of full hours, you can have

(new TotalFullHours($interval))->value();

If you want a ceiled total hours, here you go:

(new TotalCeiledHours($interval))->value();

For more about this approach and some examples, check out this entry.

This will print the full path of all files in the given directory, you can also pass other callback functions to recursiveDir.

function printFunc($path){
    echo $path."<br>";
}

function recursiveDir($path, $fileFunc, $dirFunc){
    $openDir = opendir($path);
    while (($file = readdir($openDir)) !== false) {
        $fullFilePath = realpath("$path/$file");
        if ($file[0] != ".") {
            if (is_file($fullFilePath)){
                if (is_callable($fileFunc)){
                    $fileFunc($fullFilePath);
                }
            } else {
                if (is_callable($dirFunc)){
                    $dirFunc($fullFilePath);
                }
                recursiveDir($fullFilePath, $fileFunc, $dirFunc);
            }
        }
    }
}

recursiveDir($dirToScan, 'printFunc', 'printFunc');

Actually Git maintains a copy of your own code and the remote repository.

The command git fetch makes your local copy up to date by getting data from remote repository. The reason we need this is because somebody else might have made some changes to the code and you want to keep yourself updated.

The command git pull brings the changes in the remote repository to where you keep your own code. Normally, git pull does this by doing a ‘git fetch’ first to bring the local copy of the remote repository up to date, and then it merges the changes into your own code repository and possibly your working copy.

Here is a simple solution from the source of facebook's slingshot

var isMobile = /iPhone|iPad|iPod|Android/i.test(navigator.userAgent);
if (isMobile) {
  /* your code here */
}

let str = "January,February,March,April,May,June,July,August,September,October,November,December"

let arr = str.split(',');

it will result:

["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]

and if you want to convert following to:

["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]

this:

"January,February,March,April,May,June,July,August,September,October,November,December";

use:

str = arr.join(',')

The following works on SQL2008 and above. Provides a list of both stored procedures and functions.

select distinct [Table Name] = o.Name, [Found In] = sp.Name, sp.type_desc
  from sys.objects o inner join sys.sql_expression_dependencies  sd on o.object_id = sd.referenced_id
                inner join sys.objects sp on sd.referencing_id = sp.object_id
                    and sp.type in ('P', 'FN')
  where o.name = 'YourTableName'
  order by sp.Name

The basic difference is that undefined and null represent different concepts.

If only null was available, you would not be able to determine whether null was set intentionally as the value or whether the value has not been set yet unless you used cumbersome error catching: eg

var a;

a == null; // This is true
a == undefined; // This is true;
a === undefined; // This is true;

However, if you intentionally set the value to null, strict equality with undefined fails, thereby allowing you to differentiate between null and undefined values:

var b = null;
b == null; // This is true
b == undefined; // This is true;
b === undefined; // This is false;

Check out the reference here instead of relying on people dismissively saying junk like "In summary, undefined is a JavaScript-specific mess, which confuses everyone". Just because you are confused, it does not mean that it is a mess.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/undefined

This behaviour is also not specific to JavaScript and it completes the generalised concept that a boolean result can be true, false, unknown (null), no value (undefined), or something went wrong (error).

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

@JasonTrue is correct, that stripping HTML tags should not be done via regular expressions.

It's quite simple to strip HTML tags using HtmlAgilityPack:

public string StripTags(string input) {
    var doc = new HtmlDocument();
    doc.LoadHtml(input ?? "");
    return doc.DocumentNode.InnerText;
}

button.setVisibility(button.getVisibility() == View.VISIBLE ? View.GONE : View.VISIBLE);

Makes it visible if invisible and invisible if visible

Looks like this trick works in SQL Server and is shorter (based in previous answers)

SELECT 1.0*MyInt1/MyInt2

Or:

SELECT (1.0*MyInt1)/MyInt2

The MacGyver way,just for lulz

var a = [80, 77, 88, 95, 68];_x000D_
_x000D_
console.log(eval(a.join('+'))/a.length)

You should use the print() function which is available since Python 2.6+

from __future__ import print_function  # Only needed for Python 2
print("hi there", file=f)

For Python 3 you don't need the import, since the print() function is the default.

The alternative would be to use:

f = open('myfile', 'w')
f.write('hi there\n')  # python will convert \n to os.linesep
f.close()  # you can omit in most cases as the destructor will call it

Quoting from Python documentation regarding newlines:

On output, if newline is None, any '\n' characters written are translated to the system default line separator, os.linesep. If newline is '', no translation takes place. If newline is any of the other legal values, any '\n' characters written are translated to the given string.

Sending and receiving data in JSON format using POST method

// Sending and receiving data in JSON format using POST method
//
var xhr = new XMLHttpRequest();
var url = "url";
xhr.open("POST", url, true);
xhr.setRequestHeader("Content-Type", "application/json");
xhr.onreadystatechange = function () {
    if (xhr.readyState === 4 && xhr.status === 200) {
        var json = JSON.parse(xhr.responseText);
        console.log(json.email + ", " + json.password);
    }
};
var data = JSON.stringify({"email": "[email protected]", "password": "101010"});
xhr.send(data);

Sending and receiving data in JSON format using GET method

// Sending a receiving data in JSON format using GET method
//      
var xhr = new XMLHttpRequest();
var url = "url?data=" + encodeURIComponent(JSON.stringify({"email": "[email protected]", "password": "101010"}));
xhr.open("GET", url, true);
xhr.setRequestHeader("Content-Type", "application/json");
xhr.onreadystatechange = function () {
    if (xhr.readyState === 4 && xhr.status === 200) {
        var json = JSON.parse(xhr.responseText);
        console.log(json.email + ", " + json.password);
    }
};
xhr.send();

Handling data in JSON format on the server-side using PHP

<?php
// Handling data in JSON format on the server-side using PHP
//
header("Content-Type: application/json");
// build a PHP variable from JSON sent using POST method
$v = json_decode(stripslashes(file_get_contents("php://input")));
// build a PHP variable from JSON sent using GET method
$v = json_decode(stripslashes($_GET["data"]));
// encode the PHP variable to JSON and send it back on client-side
echo json_encode($v);
?>

The limit of the length of an HTTP Get request is dependent on both the server and the client (browser) used, from 2kB - 8kB. The server should return 414 (Request-URI Too Long) status if an URI is longer than the server can handle.

Note Someone said that I could use state names instead of state values; in other words I could use xhr.readyState === xhr.DONE instead of xhr.readyState === 4 The problem is that Internet Explorer uses different state names so it's better to use state values.

If above answers don't work maybe you didn't add return value into getItem method in the custom adapter see this question and check out first answer.

200,300, 400, 500 are all very generic. If you want generic, 400 is OK.

422 is used by an increasing number of APIs, and is even used by Rails out of the box.

No matter which status code you pick for your API, someone will disagree. But I prefer 422 because I think of '400 + text status' as too generic. Also, you aren't taking advantage of a JSON-ready parser; in contrast, a 422 with a JSON response is very explicit, and a great deal of error information can be conveyed.

Speaking of JSON response, I tend to standardize on the Rails error response for this case, which is:

{
    "errors" :
    { 
        "arg1" : ["error msg 1", "error msg 2", ...]
        "arg2" : ["error msg 1", "error msg 2", ...]
    }
}

This format is perfect for form validation, which I consider the most complex case to support in terms of 'error reporting richness'. If your error structure is this, it will likely handle all your error reporting needs.

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

You only need to use LoadLibrary if you want to late bind and only resolve the imported functions at runtime. The easiest way to use a third party dll is to link against a .lib.

In reply to your edit:

Yes, the third party API should consist of a dll and/or a lib that contain the implementation and header files that declares the required types. You need to know the type definitions whichever method you use - for LoadLibrary you'll need to define function pointers, so you could just as easily write your own header file instead. Basically, you only need to use LoadLibrary if you want late binding. One valid reason for this would be if you aren't sure if the dll will be available on the target PC.

df['year_month']=df.datetime_column.apply(lambda x: str(x)[:7])

This worked fine for me, didn't think pandas would interpret the resultant string date as date, but when i did the plot, it knew very well my agenda and the string year_month where ordered properly... gotta love pandas!

If you really want to use String:

NSString *number = [[NSString alloc] initWithFormat:@"%d", 123];

But I would recommend using NSNumber:

NSNumber *number = [[NSNumber alloc] initWithInt:123];

Then just add it to the array.

[array addObject:number];

Don't forget to release it after that, since you created it above.

[number release];

HTH and if you find a bug let me know

I think sim serial Number and sim number is unique. You can try this for get sim serial number and get sim number and Don't forget to add permission in manifest file.

TelephonyManager telemamanger = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
String getSimSerialNumber = telemamanger.getSimSerialNumber();
String getSimNumber = telemamanger.getLine1Number();

And add below permission into your Androidmanifest.xml file.

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

Let me know if there is any issue.

Although it is not recommended, but if you really want to let your web application access a folder outside its deployment directory. You need to add following permission in java.policy file (path is as in the reply of Petey B)

permission java.io.FilePermission "your folder path", "write"

In your case it would be

permission java.io.FilePermission "S:/PDSPopulatingProgram/-", "write"

Here /- means any files or sub-folders inside this folder.

Warning: But by doing this, you are inviting some security risk.

If you do not want to include that your code script (as advised by others above), then simply you may do the following after generating the figure window:

1. Go to "Edit" in the figure window

2. Go to "Figure Properties"

3. At the bottom, you can type the name you want in "Figure Name" field. You can uncheck "Show Figure Number".

That's all.

Good luck.

//An example of implementation :
// we set the score of one player to a value
[Game getCurrent].scorePlayer1 = [NSNumber numberWithInteger:1];
// We copy the value in a NSNumber
NSNumber *aNumber = [Game getCurrent].scorePlayer1;
// Conversion of the NSNumber aNumber to a String with stringValue
NSString *StringScorePlayer1 = [aNumber stringValue];

When you create a flex container various default flex rules come into play.

Two of these default rules are flex-direction: row and align-items: stretch. This means that flex items will automatically align in a single row, and each item will fill the height of the container.

If you don't want flex items to stretch – i.e., like you wrote:

make its height the minimum required for holding its content

... then simply override the default with align-items: flex-start.

#a {_x000D_
  display: flex;_x000D_
  align-items: flex-start; /* NEW */_x000D_
}_x000D_
#a > div {_x000D_
  background-color: red;_x000D_
  padding: 5px;_x000D_
  margin: 2px;_x000D_
}_x000D_
#b {_x000D_
  height: auto;_x000D_
}

<div id="a">_x000D_
  <div id="b">left</div>_x000D_
  <div>_x000D_
    right<br>right<br>right<br>right<br>right<br>_x000D_
  </div>_x000D_
</div>

Here's an illustration from the flexbox spec that highlights the five values for align-items and how they position flex items within the container. As mentioned before, stretch is the default value.

Another option to undo changes that weren't staged for commit is to run:

git restore <file>

To discard changes in the working directory.

I am not sure this will help but I resolved the issue by importing mongoose like below and implementing it as below

const mongoose = require('mongoose')

_id: new mongoose.Types.ObjectId(),

It’s easy; just do the following:

rvm implode

or

rm -rf ~/.rvm

And don’t forget to remove the script calls in the following files:

• ~/.bashrc
• ~/.bash_profile
• ~/.profile

And maybe others depending on whatever shell you’re using.

This is one of the command which you can run to install apt-get:

wget http://security.ubuntu.com/ubuntu/pool/main/a/apt/apt_1.4_amd64.deb

Modify your log4j.properties file accordingly:

log4j.rootLogger=TRACE,stdout
...
log4j.logger.debugLog=TRACE,debugLog
log4j.logger.reportsLog=DEBUG,reportsLog

Change the log levels for each logger depending to your needs.

Depending on what you are doing, system() or popen() may be perfect. Use system() if the Python script has no output, or if you want the Python script's output to go directly to the browser. Use popen() if you want to write data to the Python script's standard input, or read data from the Python script's standard output in php. popen() will only let you read or write, but not both. If you want both, check out proc_open(), but with two way communication between programs you need to be careful to avoid deadlocks, where each program is waiting for the other to do something.

If you want to pass user supplied data to the Python script, then the big thing to be careful about is command injection. If you aren't careful, your user could send you data like "; evilcommand ;" and make your program execute arbitrary commands against your will.

escapeshellarg() and escapeshellcmd() can help with this, but personally I like to remove everything that isn't a known good character, using something like

preg_replace('/[^a-zA-Z0-9]/', '', $str)

In my case, I found (after much hair-pulling) that the "pending" status was caused by the AdBlock extension. The image that I couldn't get to load had the word "ad" in the URL, so AdBlock kept it from loading.

Disabling AdBlock fixes this issue.

Renaming the file so that it doesn't contain "ad" in the URL also fixes it, and is obviously a better solution. Unless it's an advertisement, in which case you should leave it like that. :)

If you do not care about sign your program when you publish, just right click your project then choose Properties --> Signing --> un-check Sign the ClickOnce manifest . I had the same issue when building my program on another machine which did not have ClickOne.

The binary_crossentropy(y_target, y_predict) doesn't need to apply in binary classification problem. .

In the source code of binary_crossentropy(), the nn.sigmoid_cross_entropy_with_logits(labels=target, logits=output) TensorFlow function was actually used. And, in the documentation, it says that:

Measures the probability error in discrete classification tasks in which each class is independent and not mutually exclusive. For instance, one could perform multilabel classification where a picture can contain both an elephant and a dog at the same time.

process.argv is your friend, capturing command line args is natively supported in Node JS. See example below::

process.argv.forEach((val, index) => {
  console.log(`${index}: ${val}`);
})

The jQuery docs say to use prop() for things like disabled, checked, etc. Also the more concise way is to use their selectors engine. So to disable all form elements in a div or form parent.

$myForm.find(':input:not(:disabled)').prop('disabled',true);

And to enable again you could do

$myForm.find(':input:disabled').prop('disabled',false);

I would think so. Why not? Wouldn't be much of a CDN w/o offering the CSS to support the script files

This link suggests that they are:

We find it particularly exciting that the jQuery UI CSS themes are now hosted on Google's Ajax Libraries CDN.

since it's a list it cannot be taken directly into range function as the singular integer value of the list is missing.

use this

for i in range(len(myList)):

with this, we get the singular integer value which can be used easily

I had the same problem and I could solve it by adding the entity into persistence.xml. The problem was caused due to the fact that the entity was not added to the persistence config. Edit your persistence file:

<persistence-unit name="MY_PU" transaction-type="RESOURCE_LOCAL">
<provider>`enter code here`
     org.hibernate.jpa.HibernatePersistenceProvider
  </provider>
<class>mypackage.MyEntity</class>

...

int number = 123;

stringstream = s;

s << number;

cout << ss.str() << endl;

Just so that we have some other options: reset($arr); good enough if you're not trying to keep the array pointer in place, and with very large arrays it incurs an minimal amount of overhead. That said, there are some problems with it:

$arr = array(1,2);
current($arr); // 1
next($arr);    // 2
current($arr); // 2
reset($arr);   // 1
current($arr); // 1 !This was 2 before! We've changed the array's pointer.

The way to do this without changing the pointer:

$arr[reset(array_keys($arr))]; // OR
reset(array_values($arr));

The benefit of $arr[reset(array_keys($arr))]; is that it raises an warning if the array is actually empty.

This also works:

I just changed with this.state.color==='white'?'black':'white'.

You can also pick the color from drop-down values and update in place of 'black';

I hope this comment will help you to find out your local & server file path using terminal

 find "$(cd ..; pwd)" -name "filename"

Or just you want to see your Current location then run

 pwd "filename"

I have proposed in StackOverflow question a way to run a batch file in the background (no DOS windows displayed)

That should answer your question.

Here it is:

From your first script, call your second script with the following line:

wscript.exe invis.vbs run.bat %*

Actually, you are calling a vbs script with:

• the [path]\name of your script
• all the other arguments needed by your script (%*)

Then, invis.vbs will call your script with the Windows Script Host Run() method, which takes:

• intWindowStyle : 0 means "invisible windows"
• bWaitOnReturn : false means your first script does not need to wait for your second script to finish

See the question for the full invis.vbs script:

Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.Run """" & WScript.Arguments(0) & """" & sargs, 0, False
                                                         ^
                             means "invisible window" ---| 

Update after Tammen's feedback:

If you are in a DOS session and you want to launch another script "in the background", a simple /b (as detailed in the same aforementioned question) can be enough:

You can use start /b second.bat to launch a second batch file asynchronously from your first that shares your first one's window.

The admin and manager apps are two separate things. Here's a snapshot of a tomcat-users.xml file that works, try this:

<?xml version='1.0' encoding='utf-8'?>  
<tomcat-users>  
    <role rolename="tomcat"/>  
    <role rolename="role1"/>  
    <role rolename="manager"/>  
    <user username="tomcat" password="tomcat" roles="tomcat"/>  
    <user username="both" password="tomcat" roles="tomcat,role1"/>  
    <user username="role1" password="tomcat" roles="role1"/>  
    <user username="USERNAME" password="PASSWORD" roles="manager,tomcat,role1"/>  
</tomcat-users>  

It works for me very well

INDIRECT is the function you want to use. Like so:

=INDIRECT("'"&A5&"'!G7")

With INDIRECT you can build your formula as a text string.

Based on @Dave Syers answer I add the following class to my Spring Boot project:

@Configuration
public class StaticResourceConfiguration extends WebMvcConfigurerAdapter {

 private static final Logger LOG = LoggerFactory.getLogger(StaticResourceConfiguration.class);

 @Value("${static.path}")
 private String staticPath;

 @Override
 public void addResourceHandlers(ResourceHandlerRegistry registry) {

    if(staticPath != null) {
        LOG.info("Serving static content from " + staticPath);
        registry.addResourceHandler("/**").addResourceLocations("file:" + staticPath);
    }
 }

 // see https://stackoverflow.com/questions/27381781/java-spring-boot-how-to-map-my-my-app-root-to-index-html
 @Override
 public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("/").setViewName("redirect:/index.html");
 }
}

This allows me to start my spring boot app with the parameter --static.path like

java -jar spring-app-1.0-SNAPSHOT.jar --static.path=/path/to/my/static-files/

This can be very handy for development and testing.

With querySelectorAll you can select the elements you want without the same id using css selector:

var elems = document.querySelectorAll("#id1, #id1, #id3");

if wants to convert UTC date to milliseconds

console.log('miliseconds', date_in_mili);

Similar to @Piotr Lewandowski's answer, but within a forEach:

For users on slow connections, external scripts dynamically injected via document.write() can delay page load by tens of seconds.

Here's the issue: You can't specify font weights that don't exist in the font set from Google. Click on the SEE SPECIMEN link below the font, then scroll down to the STYLES section. There you'll see each of the "styles" available for that particular font. Sadly Google doesn't list the CSS font weights for each style. Here's how the names map to CSS font weight numbers:

Thin            100     
Extra Light     200
Light           300
Regular         400
Medium          500
Semi-Bold       600
Bold            700
Extra-Bold      800
Black           900

Note that very few fonts come in all 9 weights.

Use '_blank'. It will not only open the link in a new tab but the state of the original webpage will also remain unaffected.

On windows in a corporate environment where certificates are distributed from a single source, I found this answer solved the issue: https://stackoverflow.com/a/48212753/761755

the getText method returns a String, while the setText receives a String, so you can write it like label1.setText(nameField.getText()); in your listener.

Try this command:

find / -name file.look

EDIT: According to the comments on the original post this is a C# question.

Short answer: yes, using the this keyword.

Long answer: yes, using the this keyword, and here's an example.

class MyClass
{
   private object someData;

   public MyClass(object data)
   {
      this.someData = data;
   }

   public MyClass() : this(new object())
   {
      // Calls the previous constructor with a new object, 
      // setting someData to that object
   }
}

if you need the index just use:

import random
foo = ['a', 'b', 'c', 'd', 'e']
print int(random.random() * len(foo))
print foo[int(random.random() * len(foo))]

random.choice does the same:)

FWIW with Ansible 2.2 one can use include_role:

playbook test.yml:

- name: test
  hosts:
    - 127.0.0.1
  connection: local
  tasks:
    - include_role:
        name: test
        tasks_from: other

then in roles/test/tasks/other.yml:

- name: say something else
  shell: echo "I'm the other guy"

And invoke the playbook with: ansible-playbook test.yml to get:

TASK [test : say something else] *************
changed: [127.0.0.1]

Since Java 11 you can do it even simpler:

import java.nio.file.Files;

Files.readString(Path path);
Files.readString?(Path path, Charset cs)

This is like user3076252's answer, but you'll be choosing a different set of options:

• Project > Properties > Java Build Path
• Select Libraries tab > Alternate JRE > Installed JREs...
• Click "Search." Unless you know the exact folder name, you should choose a drive to search.

It should find your unbound JRE, but this time with all the numbers in it's name (rather than unbound), and you can select it. It will take a while to search the drive, but you can stop it at any time, and it will save the results, if any.

You need to apply DATE_FORMAT in the SELECT clause, not the WHERE clause:

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM    mytable
WHERE   create_date BETWEEN CURDATE() - INTERVAL 30 DAY AND CURDATE()

Also note that CURDATE() returns only the DATE portion of the date, so if you store create_date as a DATETIME with the time portion filled, this query will not select the today's records.

In this case, you'll need to use NOW instead:

SELECT  DATE_FORMAT(create_date, '%m/%d/%Y')
FROM    mytable
WHERE   create_date BETWEEN NOW() - INTERVAL 30 DAY AND NOW()

If I understand correctly, what you want to do is divide by the maximum value in each column. You can do this easily using broadcasting.

Starting with your example array:

import numpy as np

x = np.array([[1000,  10,   0.5],
              [ 765,   5,  0.35],
              [ 800,   7,  0.09]])

x_normed = x / x.max(axis=0)

print(x_normed)
# [[ 1.     1.     1.   ]
#  [ 0.765  0.5    0.7  ]
#  [ 0.8    0.7    0.18 ]]

x.max(0) takes the maximum over the 0th dimension (i.e. rows). This gives you a vector of size (ncols,) containing the maximum value in each column. You can then divide x by this vector in order to normalize your values such that the maximum value in each column will be scaled to 1.

If x contains negative values you would need to subtract the minimum first:

x_normed = (x - x.min(0)) / x.ptp(0)

Here, x.ptp(0) returns the "peak-to-peak" (i.e. the range, max - min) along axis 0. This normalization also guarantees that the minimum value in each column will be 0.

I am an Ionic framework user and the one I found that would consistently provide the current controller's $scope is:

angular.element(document.querySelector('ion-view[nav-view="active"]')).scope()

I suspect this can be modified to fit most scenarios regardless of framework (or not) by finding the query that will target the specific DOM element(s) that are available only during a given controller instance.

• First you need to create the Hidden Field properly

  <asp:HiddenField ID="hdntxtbxTaksit" runat="server"></asp:HiddenField>

• Then you need to set value to the hidden field

  If you aren't using Jquery you should use it:

  document.getElementById("<%= hdntxtbxTaksit.ClientID %>").value = "test";

  If you are using Jquery, this is how it should be:

  $("#<%= hdntxtbxTaksit.ClientID %>").val("test");

If you want to trim specified number of spaces from left and right, you could do this:

def remove_outer_spaces(text, num_of_leading, num_of_trailing):
    text = list(text)
    for i in range(num_of_leading):
        if text[i] == " ":
            text[i] = ""
        else:
            break

    for i in range(1, num_of_trailing+1):
        if text[-i] == " ":
            text[-i] = ""
        else:
            break
    return ''.join(text)

txt1 = "   MY name is     "
print(remove_outer_spaces(txt1, 1, 1))  # result is: "  MY name is    "
print(remove_outer_spaces(txt1, 2, 3))  # result is: " MY name is  "
print(remove_outer_spaces(txt1, 6, 8))  # result is: "MY name is"

Be careful when iterating over arrays!!

It is a common misconception that using the index of the element in the array is an acceptable way of suppressing the error you are probably familiar with:

Each child in an array should have a unique "key" prop.

However, in many cases it is not! This is anti-pattern that can in some situations lead to unwanted behavior.

Understanding the key prop

React uses the key prop to understand the component-to-DOM Element relation, which is then used for the reconciliation process. It is therefore very important that the key always remains unique, otherwise there is a good chance React will mix up the elements and mutate the incorrect one. It is also important that these keys remain static throughout all re-renders in order to maintain best performance.

That being said, one does not always need to apply the above, provided it is known that the array is completely static. However, applying best practices is encouraged whenever possible.

A React developer said in this GitHub issue:

• key is not really about performance, it's more about identity (which in turn leads to better performance). randomly assigned and changing values are not identity
• We can't realistically provide keys [automatically] without knowing how your data is modeled. I would suggest maybe using some sort of hashing function if you don't have ids
• We already have internal keys when we use arrays, but they are the index in the array. When you insert a new element, those keys are wrong.

In short, a key should be:

• Unique - A key cannot be identical to that of a sibling component.
• Static - A key should not ever change between renders.

Using the key prop

As per the explanation above, carefully study the following samples and try to implement, when possible, the recommended approach.

Bad (Potentially)

<tbody>
    {rows.map((row, i) => {
        return <ObjectRow key={i} />;
    })}
</tbody>

This is arguably the most common mistake seen when iterating over an array in React. This approach isn't technically "wrong", it's just... "dangerous" if you don't know what you are doing. If you are iterating through a static array then this is a perfectly valid approach (e.g. an array of links in your navigation menu). However, if you are adding, removing, reordering or filtering items, then you need to be careful. Take a look at this detailed explanation in the official documentation.

class MyApp extends React.Component {
  constructor() {
    super();
    this.state = {
      arr: ["Item 1"]
    }
  }
  
  click = () => {
    this.setState({
      arr: ['Item ' + (this.state.arr.length+1)].concat(this.state.arr),
    });
  }
  
  render() {
    return(
      <div>
        <button onClick={this.click}>Add</button>
        <ul>
          {this.state.arr.map(
            (item, i) => <Item key={i} text={"Item " + i}>{item + " "}</Item>
          )}
        </ul>
      </div>
    );
  }
}

const Item = (props) => {
  return (
    <li>
      <label>{props.children}</label>
      <input value={props.text} />
    </li>
  );
}

ReactDOM.render(<MyApp />, document.getElementById("app"));

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>
<div id="app"></div>

In this snippet we are using a non-static array and we are not restricting ourselves to using it as a stack. This is an unsafe approach (you'll see why). Note how as we add items to the beginning of the array (basically unshift), the value for each <input> remains in place. Why? Because the key doesn't uniquely identify each item.

In other words, at first Item 1 has key={0}. When we add the second item, the top item becomes Item 2, followed by Item 1 as the second item. However, now Item 1 has key={1} and not key={0} anymore. Instead, Item 2 now has key={0}!!

As such, React thinks the <input> elements have not changed, because the Item with key 0 is always at the top!

So why is this approach only sometimes bad?

This approach is only risky if the array is somehow filtered, rearranged, or items are added/removed. If it is always static, then it's perfectly safe to use. For example, a navigation menu like ["Home", "Products", "Contact us"] can safely be iterated through with this method because you'll probably never add new links or rearrange them.

In short, here's when you can safely use the index as key:

• The array is static and will never change.
• The array is never filtered (display a subset of the array).
• The array is never reordered.
• The array is used as a stack or LIFO (last in, first out). In other words, adding can only be done at the end of the array (i.e push), and only the last item can ever be removed (i.e pop).

Had we instead, in the snippet above, pushed the added item to the end of the array, the order for each existing item would always be correct.

Very bad

<tbody>
    {rows.map((row) => {
        return <ObjectRow key={Math.random()} />;
    })}
</tbody>

While this approach will probably guarantee uniqueness of the keys, it will always force react to re-render each item in the list, even when this is not required. This a very bad solution as it greatly impacts performance. Not to mention that one cannot exclude the possibility of a key collision in the event that Math.random() produces the same number twice.

Unstable keys (like those produced by Math.random()) will cause many component instances and DOM nodes to be unnecessarily recreated, which can cause performance degradation and lost state in child components.

Very good

<tbody>
    {rows.map((row) => {
        return <ObjectRow key={row.uniqueId} />;
    })}
</tbody>

This is arguably the best approach because it uses a property that is unique for each item in the dataset. For example, if rows contains data fetched from a database, one could use the table's Primary Key (which typically is an auto-incrementing number).

The best way to pick a key is to use a string that uniquely identifies a list item among its siblings. Most often you would use IDs from your data as keys

Good

componentWillMount() {
  let rows = this.props.rows.map(item => { 
    return {uid: SomeLibrary.generateUniqueID(), value: item};
  });
}

...

<tbody>
    {rows.map((row) => {
        return <ObjectRow key={row.uid} />;
    })}
</tbody>

This is also a good approach. If your dataset does not contain any data that guarantees uniqueness (e.g. an array of arbitrary numbers), there is a chance of a key collision. In such cases, it is best to manually generate a unique identifier for each item in the dataset before iterating over it. Preferably when mounting the component or when the dataset is received (e.g. from props or from an async API call), in order to do this only once, and not each time the component re-renders. There are already a handful of libraries out there that can provide you such keys. Here is one example: react-key-index.

Based on the given answers and information in the question, this is the code you should use:

public static boolean doesURLExist(URL url) throws IOException
{
    // We want to check the current URL
    HttpURLConnection.setFollowRedirects(false);

    HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();

    // We don't need to get data
    httpURLConnection.setRequestMethod("HEAD");

    // Some websites don't like programmatic access so pretend to be a browser
    httpURLConnection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)");
    int responseCode = httpURLConnection.getResponseCode();

    // We only accept response code 200
    return responseCode == HttpURLConnection.HTTP_OK;
}

Of course tested and working.

The legacy solution, before 1.6, was to use .attr and handle the returned value as a bool. The main problem is that the returned type of .attr has changed to string, and therefore the comparison with == true is broken (see http://jsfiddle.net/2vene/1/ (and switch the jquery-version)).

With 1.6 .prop was introduced, which returns a bool.

Nevertheless, I suggest to use .is(), as the returned type is intrinsically bool, like:

$('#dropUnit').is(':disabled');
$('#dropUnit').is(':enabled');

Furthermore .is() is much more natural (in terms of "natural language") and adds more conditions than a simple attribute-comparison (eg: .is(':last'), .is(':visible'), ... please see documentation on selectors).

As Paul Turner answered Socket.Connected cannot be used in this situation. You need to poll connection every time to see if connection is still active. This is code I used:

bool SocketConnected(Socket s)
{
    bool part1 = s.Poll(1000, SelectMode.SelectRead);
    bool part2 = (s.Available == 0);
    if (part1 && part2)
        return false;
    else
        return true;
}

It works like this:

• s.Poll returns true if
  • connection is closed, reset, terminated or pending (meaning no active connection)
  • connection is active and there is data available for reading
• s.Available returns number of bytes available for reading
• if both are true:
  • there is no data available to read so connection is not active

In Sublime Text 3....Try changing the above code to this, note the addition of "start".....

"variants" : [

    { "name": "Run",
      "cmd" : ["start", "${file_base_name}.exe"]
    } 

std::string var = "sometext" + somevar + "sometext" + somevar;

This doesn't work because the additions are performed left-to-right and "sometext" (the first one) is just a const char *. It has no operator+ to call. The simplest fix is this:

std::string var = std::string("sometext") + somevar + "sometext" + somevar;

Now, the first parameter in the left-to-right list of + operations is a std::string, which has an operator+(const char *). That operator produces a string, which makes the rest of the chain work.

You can also make all the operations be on var, which is a std::string and so has all the necessary operators:

var = "sometext";
var += somevar;
var += "sometext";
var += somevar;

If you need a zero padded difference between 2 dates:

SELECT convert(varchar(2),FORMAT(DATEDIFF(s, @startDate, @endDate)/3600,'0#'))+':'    
   +convert(varchar(2),FORMAT(DATEDIFF(s, @startDate, @endDate)%3600/60,'0#'))+':'
   +convert(varchar(2),FORMAT(DATEDIFF(s, @startDate, @endDate)%60,'0#')) AS Duration

By passing parameters by reference to function.

Examples:

 void incInt(int *y)
 {
     (*y)++;  // Increase the value of 'x', in main, by one.
 }

Also by using global variables but it is not recommended.

Example:

int a=0;

void main(void)
{
    //Anything you want to code.
}

If you want to use a function form a package or module in python you have to import and reference them. For example normally you do the following to draw 5 points( [1,5],[2,4],[3,3],[4,2],[5,1]) in the space:

import matplotlib.pyplot
matplotlib.pyplot.plot([1,2,3,4,5],[5,4,3,2,1],"bx")
matplotlib.pyplot.show()

In your solution

from matplotlib import*

This imports the package matplotlib and "plot is not defined" means there is no plot function in matplotlib you can access directly, but instead if you import as

from matplotlib.pyplot import *
plot([1,2,3,4,5],[5,4,3,2,1],"bx")
show()

Now you can use any function in matplotlib.pyplot without referencing them with matplotlib.pyplot.

I would recommend you to name imports you have, in this case you can prevent disambiguation and future problems with the same function names. The last and clean version of above example looks like:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4,5],[5,4,3,2,1],"bx")
plt.show()

The right way is:

db.users.find({awards: {$elemMatch: {award:'National Medal', year:1975}}})

$elemMatch allows you to match more than one component within the same array element.

Without $elemMatch mongo will look for users with National Medal in some year and some award in 1975s, but not for users with National Medal in 1975.

See MongoDB $elemMatch Documentation for more info. See Read Operations Documentation for more information about querying documents with arrays.

You could also use HttpURLConnection, which allows you to set the request method (to HEAD for example). Here's an example that shows how to send a request, read the response, and disconnect.

The easiest solution is to download the Android SDK bundle:

http://developer.android.com/sdk/installing/bundle.html

The ADT Bundle provides everything you need to start developing apps, including a version of the Eclipse IDE with built-in ADT (Android Developer Tools) to streamline your Android app development.

Yes, it prints GARBAGE unless you are lucky.

VERY IMPORTANT.

The type of the printf/sprintf/fprintf argument MUST match the associated format type char.

If the types don't match and it compiles, the results are very undefined.

Many newer compilers know about printf and issue warnings if the types do not match. If you get these warnings, FIX them.

If you want to convert types for arguments for variable functions, you must supply the cast (ie, explicit conversion) because the compiler can't figure out that a conversion needs to be performed (as it can with a function prototype with typed arguments).

printf("%d\n", (int) ch)

In this example, printf is being TOLD that there is an "int" on the stack. The cast makes sure that whatever thing sizeof returns (some sort of long integer, usually), printf will get an int.

printf("%d", (int) sizeof('\n'))

I followed the steps at https://www.w3schools.com/php/php_file_upload.asp and http://www.w3bees.com/2013/03/resize-image-while-upload-using-php.html to produce this solution:

In my view (I am using the MVC paradigm, but it could be your .html or .php file, or the technology that you use for your front-end):

<form action="../../photos/upload.php" method="post" enctype="multipart/form-data">
<label for="quantity">Width:</label>
  <input type="number" id="picture_width" name="picture_width" min="10" max="800" step="1" value="500">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>

My upload.php:

<?php
/* Get original image x y*/
list($w, $h) = getimagesize($_FILES['fileToUpload']['tmp_name']);
$new_height=$h*$_POST['picture_width']/$w;
/* calculate new image size with ratio */
$ratio = max($_POST['picture_width']/$w, $new_height/$h);
$h = ceil($new_height / $ratio);
$x = ($w - $_POST['picture_width'] / $ratio) / 2;
$w = ceil($_POST['picture_width'] / $ratio);
/* new file name */
//$path = 'uploads/'.$_POST['picture_width'].'x'.$new_height.'_'.basename($_FILES['fileToUpload']['name']);
$path = 'uploads/'.basename($_FILES['fileToUpload']['name']);
/* read binary data from image file */
$imgString = file_get_contents($_FILES['fileToUpload']['tmp_name']);
/* create image from string */
$image = imagecreatefromstring($imgString);
$tmp = imagecreatetruecolor($_POST['picture_width'], $new_height);
imagecopyresampled($tmp, $image,
    0, 0,
    $x, 0,
    $_POST['picture_width'], $new_height,
    $w, $h);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($path,PATHINFO_EXTENSION));
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        //echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        //echo "File is not an image.";
        $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($path)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
    // if everything is ok, try to upload file
} else {
    /* Save image */
    switch ($_FILES['fileToUpload']['type']) {
        case 'image/jpeg':
            imagejpeg($tmp, $path, 100);
            break;
        case 'image/png':
            imagepng($tmp, $path, 0);
            break;
        case 'image/gif':
            imagegif($tmp, $path);
            break;
        default:
            exit;
            break;
    }
    echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    /* cleanup memory */
    imagedestroy($image);
    imagedestroy($tmp);
}
?>

The name of the folder where pictures are stored is called 'uploads/'. You need to have that folder previously created and that is where you will see your pictures. It works great for me.

NOTE: This is my form:

The code is uploading and resizing pictures properly. I used this link as a guide: http://www.w3bees.com/2013/03/resize-image-while-upload-using-php.html. I modified it because in that code they specify both width and height of resized pictures. In my case, I only wanted to specify width. The height I automatically calculated it proportionally, just keeping proper picture proportions. Everything works perfectly. I hope this helps.

Case-insensitive searching comes built-in with Rails. It accounts for differences in database implementations. Use either the built-in Arel library, or a gem like Squeel.

So do you want them to get the IE password-challenge box, or should they be directed to your login page and enter their information there? If it's the second option, then you should at least enable Anonymous access to your login page, since the site won't know who they are yet.

If you want the first option, then the login page they're getting forwarded to will need to read the currently logged-in user and act based on that, since they would have had to correctly authenticate to get this far.

I used subprocess.call it's almost same like subprocess.Popen

from subprocess import call
call(["python", "your_file.py"])

I find myself using the following often to get a limited number of revisions out of our huge subversion tree (we're soon reaching svn revision 35000).

# checkout a specific revision
git svn clone -r N svn://some/repo/branch/some-branch
# enter it and get all commits since revision 'N'
cd some-branch
git svn rebase

And a good way to find out where a branch started is to do a svn log it and find the first one on the branch (the last one listed when doing):

svn log --stop-on-copy svn://some/repo/branch/some-branch

So far I have not really found the hassle worth it in tracking all branches. It takes too much time to clone and svn and git don't work together as good as I would like. I tend to create patch files and apply them on the git clone of another svn branch.

Place this on your model:

[DisplayName("Electric Fan")]
public bool ElectricFan { get; set; }

private string electricFanRate;

public string ElectricFanRate
{
    get { return electricFanRate ?? (electricFanRate = "$15/month"); }
    set { electricFanRate = value; }
}

And this in your cshtml:

<div class="row">
    @Html.CheckBoxFor(m => m.ElectricFan, new { @class = "" })
    @Html.LabelFor(m => m.ElectricFan, new { @class = "" })
    @Html.DisplayTextFor(m => m.ElectricFanRate)
</div>

Which will output this:

If you click on the checkbox or the bold label it will check/uncheck the checkbox

In Python 3, TemporaryDirectory in the tempfile module can be used.

This is straight from the examples:

import tempfile
with tempfile.TemporaryDirectory() as tmpdirname:
     print('created temporary directory', tmpdirname)
# directory and contents have been removed

If you would like to keep the directory a bit longer, you could do something like this:

import tempfile

temp_dir = tempfile.TemporaryDirectory()
print(temp_dir.name)
# use temp_dir, and when done:
temp_dir.cleanup()

The documentation also says that "On completion of the context or destruction of the temporary directory object the newly created temporary directory and all its contents are removed from the filesystem." So at the end of the program, for example, Python will clean up the directory if it wasn't explicitly removed. Python's unittest may complain of ResourceWarning: Implicitly cleaning up <TemporaryDirectory... if you rely on this, though.

I did what @ang_lee said and also i added this line to the app theme style :

<item name="windowActionBar">false</item>

i am using version 26.0.1 :

com.android.support:design:26.0.1
com.android.support:appcompat-v7:26.0.1

building tools:

buildToolsVersion "26.0.1"

Try this code. You can change the height and width percentages with app:layout_constraintHeight_percent and app:layout_constraintWidth_percent.

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:background="#FF00FF"
        android:orientation="vertical"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintHeight_percent=".6"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintWidth_percent=".4"></LinearLayout>

</android.support.constraint.ConstraintLayout>

Gradle:

dependencies {

    implementation 'com.android.support.constraint:constraint-layout:1.1.3'

I always have to look this one up time and time again, so here is my answer.

Asserting multiple method calls on different objects of the same class

Suppose we have a heavy duty class (which we want to mock):

In [1]: class HeavyDuty(object):
   ...:     def __init__(self):
   ...:         import time
   ...:         time.sleep(2)  # <- Spends a lot of time here
   ...:     
   ...:     def do_work(self, arg1, arg2):
   ...:         print("Called with %r and %r" % (arg1, arg2))
   ...:  

here is some code that uses two instances of the HeavyDuty class:

In [2]: def heavy_work():
   ...:     hd1 = HeavyDuty()
   ...:     hd1.do_work(13, 17)
   ...:     hd2 = HeavyDuty()
   ...:     hd2.do_work(23, 29)
   ...:    

Now, here is a test case for the heavy_work function:

In [3]: from unittest.mock import patch, call
   ...: def test_heavy_work():
   ...:     expected_calls = [call.do_work(13, 17),call.do_work(23, 29)]
   ...:     
   ...:     with patch('__main__.HeavyDuty') as MockHeavyDuty:
   ...:         heavy_work()
   ...:         MockHeavyDuty.return_value.assert_has_calls(expected_calls)
   ...:  

We are mocking the HeavyDuty class with MockHeavyDuty. To assert method calls coming from every HeavyDuty instance we have to refer to MockHeavyDuty.return_value.assert_has_calls, instead of MockHeavyDuty.assert_has_calls. In addition, in the list of expected_calls we have to specify which method name we are interested in asserting calls for. So our list is made of calls to call.do_work, as opposed to simply call.

Exercising the test case shows us it is successful:

In [4]: print(test_heavy_work())
None

If we modify the heavy_work function, the test fails and produces a helpful error message:

In [5]: def heavy_work():
   ...:     hd1 = HeavyDuty()
   ...:     hd1.do_work(113, 117)  # <- call args are different
   ...:     hd2 = HeavyDuty()
   ...:     hd2.do_work(123, 129)  # <- call args are different
   ...:     

In [6]: print(test_heavy_work())
---------------------------------------------------------------------------
(traceback omitted for clarity)

AssertionError: Calls not found.
Expected: [call.do_work(13, 17), call.do_work(23, 29)]
Actual: [call.do_work(113, 117), call.do_work(123, 129)]

Asserting multiple calls to a function

To contrast with the above, here is an example that shows how to mock multiple calls to a function:

In [7]: def work_function(arg1, arg2):
   ...:     print("Called with args %r and %r" % (arg1, arg2))

In [8]: from unittest.mock import patch, call
   ...: def test_work_function():
   ...:     expected_calls = [call(13, 17), call(23, 29)]    
   ...:     with patch('__main__.work_function') as mock_work_function:
   ...:         work_function(13, 17)
   ...:         work_function(23, 29)
   ...:         mock_work_function.assert_has_calls(expected_calls)
   ...:    

In [9]: print(test_work_function())
None

There are two main differences. The first one is that when mocking a function we setup our expected calls using call, instead of using call.some_method. The second one is that we call assert_has_calls on mock_work_function, instead of on mock_work_function.return_value.

You can use SelectionChanged event since you are using FullRowSelect selection mode. Than inside the handler you can access SelectedRows property and get data from it. Example:

private void dataGridView_SelectionChanged(object sender, EventArgs e) 
{
    foreach (DataGridViewRow row in dataGridView.SelectedRows) 
    {
        string value1 = row.Cells[0].Value.ToString();
        string value2 = row.Cells[1].Value.ToString();
        //...
    }
}

You can also walk through the column collection instead of typing indexes...

In your case, breaking the hash algorithm is equivalent to finding a collision in the hash algorithm. That means you don't need to find the password itself (which would be a preimage attack), you just need to find an output of the hash function that is equal to the hash of a valid password (thus "collision"). Finding a collision using a birthday attack takes O(2^(n/2)) time, where n is the output length of the hash function in bits.

SHA-2 has an output size of 512 bits, so finding a collision would take O(2^256) time. Given there are no clever attacks on the algorithm itself (currently none are known for the SHA-2 hash family) this is what it takes to break the algorithm.

To get a feeling for what 2^256 actually means: currently it is believed that the number of atoms in the (entire!!!) universe is roughly 10^80 which is roughly 2^266. Assuming 32 byte input (which is reasonable for your case - 20 bytes salt + 12 bytes password) my machine takes ~0,22s (~2^-2s) for 65536 (=2^16) computations. So 2^256 computations would be done in 2^240 * 2^16 computations which would take

2^240 * 2^-2 = 2^238 ~ 10^72s ~ 3,17 * 10^64 years

Even calling this millions of years is ridiculous. And it doesn't get much better with the fastest hardware on the planet computing thousands of hashes in parallel. No human technology will be able to crunch this number into something acceptable.

So forget brute-forcing SHA-256 here. Your next question was about dictionary words. To retrieve such weak passwords rainbow tables were used traditionally. A rainbow table is generally just a table of precomputed hash values, the idea is if you were able to precompute and store every possible hash along with its input, then it would take you O(1) to look up a given hash and retrieve a valid preimage for it. Of course this is not possible in practice since there's no storage device that could store such enormous amounts of data. This dilemma is known as memory-time tradeoff. As you are only able to store so many values typical rainbow tables include some form of hash chaining with intermediary reduction functions (this is explained in detail in the Wikipedia article) to save on space by giving up a bit of savings in time.

Salts were a countermeasure to make such rainbow tables infeasible. To discourage attackers from precomputing a table for a specific salt it is recommended to apply per-user salt values. However, since users do not use secure, completely random passwords, it is still surprising how successful you can get if the salt is known and you just iterate over a large dictionary of common passwords in a simple trial and error scheme. The relationship between natural language and randomness is expressed as entropy. Typical password choices are generally of low entropy, whereas completely random values would contain a maximum of entropy.

The low entropy of typical passwords makes it possible that there is a relatively high chance of one of your users using a password from a relatively small database of common passwords. If you google for them, you will end up finding torrent links for such password databases, often in the gigabyte size category. Being successful with such a tool is usually in the range of minutes to days if the attacker is not restricted in any way.

That's why generally hashing and salting alone is not enough, you need to install other safety mechanisms as well. You should use an artificially slowed down entropy-enducing method such as PBKDF2 described in PKCS#5 and you should enforce a waiting period for a given user before they may retry entering their password. A good scheme is to start with 0.5s and then doubling that time for each failed attempt. In most cases users don't notice this and don't fail much more often than three times on average. But it will significantly slow down any malicious outsider trying to attack your application.

This solution handles namespaces, attributes, and produces consistent result with repeating elements (always in array, even if there is only one occurrence). Inspired by ratfactor's sxiToArray().

Although I have seen the suggested methods used and working, I think that setting the value of an hidden field only using the JSON.stringify breaks the HTML...

Here I'll explain what I mean:

<input type="hidden" value="{"name":"John"}">

As you can see the first double quote after the open chain bracket could be interpreted by some browsers as:

<input type="hidden" value="{" rubbish >

So for a better approach to this I would suggest to use the encodeURIComponent function. Together with the JSON.stringify we shold have something like the following:

> encodeURIComponent(JSON.stringify({"name":"John"}))
> "%7B%22name%22%3A%22John%22%7D"

Now that value can be safely stored in an input hidden type like so:

<input type="hidden" value="%7B%22name%22%3A%22John%22%7D">

or (even better) using the data- attribute of the HTML element manipulated by the script that will consume the data, like so:

<div id="something" data-json="%7B%22name%22%3A%22John%22%7D"></div>

Now to read the data back we can do something like:

> var data = JSON.parse(decodeURIComponent(div.getAttribute("data-json")))
> console.log(data)
> Object {name: "John"}

Legacy. List was originally defined to be functional-languages-looking:

1 :: 2 :: Nil // a list
list1 ::: list2  // concatenation of two lists

list match {
  case head :: tail => "non-empty"
  case Nil          => "empty"
}

Of course, Scala evolved other collections, in an ad-hoc manner. When 2.8 came out, the collections were redesigned for maximum code reuse and consistent API, so that you can use ++ to concatenate any two collections -- and even iterators. List, however, got to keep its original operators, aside from one or two which got deprecated.

I'm using this

DELETE TableA 
FROM TableA a
INNER JOIN
TableB b on b.Bid = a.Bid
AND [condition]

and @TheTXI way is good as enough but I read answers and comments and I found one things must be answered is using condition in WHERE clause or as join condition. So I decided to test it and write an snippet but didn't find a meaningful difference between them. You can see sql script here and important point is that I preferred to write it as commnet because of this is not exact answer but it is large and can't be put in comments, please pardon me.

Declare @TableA  Table
(
  aId INT,
  aName VARCHAR(50),
  bId INT
)
Declare @TableB  Table
(
  bId INT,
  bName VARCHAR(50)  
)

Declare @TableC  Table
(
  cId INT,
  cName VARCHAR(50),
  dId INT
)
Declare @TableD  Table
(
  dId INT,
  dName VARCHAR(50)  
)

DECLARE @StartTime DATETIME;
SELECT @startTime = GETDATE();

DECLARE @i INT;

SET @i = 1;

WHILE @i < 1000000
BEGIN
  INSERT INTO @TableB VALUES(@i, 'nameB:' + CONVERT(VARCHAR, @i))
  INSERT INTO @TableA VALUES(@i+5, 'nameA:' + CONVERT(VARCHAR, @i+5), @i)

  SET @i = @i + 1;
END

SELECT @startTime = GETDATE()

DELETE a
--SELECT *
FROM @TableA a
Inner Join @TableB b
ON  a.BId = b.BId
WHERE a.aName LIKE '%5'

SELECT Duration = DATEDIFF(ms,@StartTime,GETDATE())

SET @i = 1;
WHILE @i < 1000000
BEGIN
  INSERT INTO @TableD VALUES(@i, 'nameB:' + CONVERT(VARCHAR, @i))
  INSERT INTO @TableC VALUES(@i+5, 'nameA:' + CONVERT(VARCHAR, @i+5), @i)

  SET @i = @i + 1;
END

SELECT @startTime = GETDATE()

DELETE c
--SELECT *
FROM @TableC c
Inner Join @TableD d
ON  c.DId = d.DId
AND c.cName LIKE '%5'

SELECT Duration    = DATEDIFF(ms,@StartTime,GETDATE())

If you could get good reason from this script or write another useful, please share. Thanks and hope this help.

Messa's answer only works if the server isn't bothering to check the content-type header. You'll need to specify a content-type header if you want it to really work. Here's Messa's answer modified to include a content-type header:

import json
import urllib2
data = json.dumps([1, 2, 3])
req = urllib2.Request(url, data, {'Content-Type': 'application/json'})
f = urllib2.urlopen(req)
response = f.read()
f.close()

This is what you need :)

The following code will return a JavaScript Object containing the URL parameters:

// Read a page's GET URL variables and return them as an associative array.
function getUrlVars()
{
    var vars = [], hash;
    var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
    for(var i = 0; i < hashes.length; i++)
    {
        hash = hashes[i].split('=');
        vars.push(hash[0]);
        vars[hash[0]] = hash[1];
    }
    return vars;
}

For example, if you have the URL:

http://www.example.com/?me=myValue&name2=SomeOtherValue

This code will return:

{
    "me"    : "myValue",
    "name2" : "SomeOtherValue"
}

and you can do:

var me = getUrlVars()["me"];
var name2 = getUrlVars()["name2"];

The best way is to create a variable of type Worksheet, assign the worksheet and use it every time the VBA would implicitly use the ActiveSheet.

This will help you avoid bugs that will eventually show up when your program grows in size.

For example something like Range("A1:C10").Sort Key1:=Range("A2") is good when the macro works only on one sheet. But you will eventually expand your macro to work with several sheets, find out that this doesn't work, adjust it to ShTest1.Range("A1:C10").Sort Key1:=Range("A2")... and find out that it still doesn't work.

Here is the correct way:

Dim ShTest1 As Worksheet
Set ShTest1 = Sheets("Test1")
ShTest1.Range("A1:C10").Sort Key1:=ShTest1.Range("A2")

You need convert list to numpy array and then reshape:

df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)
   a  b  c
0  1  2  3
1  4  5  6
2  7  8  9

I was facing the same problem because some of the images are grey scale images in my data set, so i solve my problem by doing this

    from PIL import Image
    img = Image.open('my_image.jpg').convert('RGB')
    # a line from my program
    positive_images_array = np.array([np.array(Image.open(img).convert('RGB').resize((150, 150), Image.ANTIALIAS)) for img in images_in_yes_directory])

If we are talking Visual Studio Code nowadays you set a default formatter in your settings.json:

  // Defines a default formatter which takes precedence over all other formatter settings. 
  // Must be the identifier of an extension contributing a formatter.
  "editor.defaultFormatter": null,

Point to the identifier of any installed extension, i.e.

"editor.defaultFormatter": "esbenp.prettier-vscode"

You can also do so format-specific:

"[html]": {
    "editor.defaultFormatter": "esbenp.prettier-vscode"
},
"[scss]": {
    "editor.defaultFormatter": "esbenp.prettier-vscode"
},
"[sass]": {
    "editor.defaultFormatter": "michelemelluso.code-beautifier"
},

Also see here.

You could also assign other keys for different formatters in your keyboard shortcuts (keybindings.json). By default, it reads:

{
  "key": "shift+alt+f",
  "command": "editor.action.formatDocument",
  "when": "editorHasDocumentFormattingProvider && editorHasDocumentFormattingProvider && editorTextFocus && !editorReadonly"
}

Lastly, if you decide to use the Prettier plugin and prettier.rc, and you want for example different indentation for html, scss, json...

{
    "semi": true,
    "singleQuote": false,
    "trailingComma": "none",
    "useTabs": false,

    "overrides": [
        {
            "files": "*.component.html",
            "options": {
                "parser": "angular",
                "tabWidth": 4
            }
        },
        {
            "files": "*.scss",
            "options": {
                "parser": "scss",
                "tabWidth": 2
            }
        },
        {
            "files": ["*.json", ".prettierrc"],
            "options": {
                "parser": "json",
                "tabWidth": 4
            }
        }
    ]
}
