Programs & Examples On #Xrandr

First off, Xvfb doesn't read configuration from xorg.conf. Xvfb is a variant of the KDrive X servers and like all members of that family gets its configuration from the command line.

It is true that XRandR and Xinerama are mutually exclusive, but in the case of Xvfb there's no Xinerama in the first place. You can enable the XRandR extension by starting Xvfb using at least the following command line options

Xvfb +extension RANDR [further options]

string[][] table = { ... };

Use all SQL server: ;with tbl as (SELECT ROW_NUMBER() over(order by(select 1)) as RowIndex,* from table) select top 10 * from tbl where RowIndex>=10

You're using a relative url, which is relative to the current url, not the file system. You could resolve this by using absolute urls

<img src ="http://localhost:3000/details/img/myImage.png" />

But that's not great for when you deploy to www.my-domain.bike, or any other site. Better would be to use a url relative to the root directory of the site

<img src="/details/img/myImage.png" />

I know this is old and whatnot (and not exactly sure if it's a question), but after searching, I had success with this command for --onefile:

pyinstaller.exe --onefile --windowed --icon=app.ico app.py

Google led me to this page while I was searching for an answer on how to set an icon for my .exe, so maybe it will help someone else.

The information here was found at this site: https://mborgerson.com/creating-an-executable-from-a-python-script

There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.

This can not have a variable:

create function Func() returns table
as
return
select 10 as ColName

You have to do like this instead:

create function Func()
returns @T table(ColName int)
as
begin
  declare @Var int
  set @Var = 10
  insert into @T(ColName) values (@Var)
  return
end

SELECT [UserID] FROM [User] u LEFT JOIN (
SELECT [TailUser], [Weight] FROM [Edge] WHERE [HeadUser] = 5043) t on t.TailUser=u.USerID

I'm not entirely sure why, but my Postgres installation got a little bit screwed and some files were deleted resulting in the error OP is showing.

Despite the fact that I am able to run commands like brew service retart postgres and see the proper messages, this error persisted.

I went through the postgres documentation and found that my file /usr/local/var/postgres was totally empty. So I ran the following:

initdb /usr/local/var/postgres

It seems some configurations took place with that command.

Then it asked me to run this:

postgres -D /usr/local/var/postgres

And that told me a postmaster.pid file already exists.

I just needed to know if brew would be able to pick up the configs I just ran, so I tested it out.

ls /usr/local/var/postgres

That showed me a postmaster.pid file. I then did brew services stop postgresql, and the postmaster.pid file disappeared. Then I did brew services start postgresql, and VIOLA, the file reappeared.

Then I went ahead and ran my app, which did in fact find the server, however my databases seem to be gone.

Although I know that they may not be gone at all - the new initialization I did may have created a new data_area, and the old one isn't being pointed to. I'd have to look at where that's at and point it back over or just create my databases again.

Hope this helps! Reading the postgres docs helped me a lot. I hate reading answers that are like "Paste this in it works!" because I don't know what the hell is happening and why.

I prefer going the long route. These are the checks I follow to avoid using a try-except clause -

1. check if variable is not None
2. then check if its a dataframe and
3. make sure its not empty

Here, DATA is the suspect variable -

DATA is not None and isinstance(DATA, pd.DataFrame) and not DATA.empty

encodeURI()/decodeURI and encodeURIComponent()/decodeURIComponent are utility functions to handle this. Read more here https://stackabuse.com/javascripts-encodeuri-function/

Oracle doesn't have autoincrementing columns. You need a sequence and a trigger. Here's a random blog post that explains how to do it: http://www.lifeaftercoffee.com/2006/02/17/how-to-create-auto-increment-columns-in-oracle/

The array module is kind of one of those things that you probably don't have a need for if you don't know why you would use it (and take note that I'm not trying to say that in a condescending manner!). Most of the time, the array module is used to interface with C code. To give you a more direct answer to your question about performance:

Arrays are more efficient than lists for some uses. If you need to allocate an array that you KNOW will not change, then arrays can be faster and use less memory. GvR has an optimization anecdote in which the array module comes out to be the winner (long read, but worth it).

On the other hand, part of the reason why lists eat up more memory than arrays is because python will allocate a few extra elements when all allocated elements get used. This means that appending items to lists is faster. So if you plan on adding items, a list is the way to go.

TL;DR I'd only use an array if you had an exceptional optimization need or you need to interface with C code (and can't use pyrex).

Thanks for your feed back got it to work I used the sshpass tool.

sshpass -p 'password' scp [email protected]:sys_config /var/www/dev/

Since ant 1.9.1 you can use a if:set condition : https://ant.apache.org/manual/ifunless.html

You can achieve this using the apache commons java library. Take a look at these two functions within it:
- getLevenshteinDistance
- getFuzzyDistance

You should use htmlspecialchars. It replaces characters as below:

• & (ampersand) becomes &
• " (double quote) becomes " when ENT_NOQUOTES is not set.
• ' (single quote) becomes ' only when ENT_QUOTES is set.
• < (less than) becomes <
• > (greater than) becomes >

You can just use exec to replace your current shell with a new shell:

Switch to bash:

exec bash

Switch to zsh:

exec zsh

This won't affect new terminal windows or anything, but it's convenient.

You need to change permissions on the folder bootstrap/css. Your super user may be able to access it but it doesn't mean apache or nginx have access to it, that's why you still need to change the permissions.

Tip: I usually make the apache/nginx's user group owner of that kind of folders and give 775 permission to it.

The window is the actual global object.

The screen is the screen, it contains properties about the user's display.

The document is where the DOM is.

I suppose better would be to use re.match() function. here is an example which may help you.

import re
import nltk
from nltk.tokenize import word_tokenize
nltk.download('punkt')
sentences = word_tokenize("I love to learn NLP \n 'a :(")
#for i in range(len(sentences)):
sentences = [word.lower() for word in sentences if re.match('^[a-zA-Z]+', word)]  
sentences

Update for Angular 2 final version

In app.module.ts:

• Add imports:

    import { HashLocationStrategy, LocationStrategy } from '@angular/common';
  

• And in NgModule provider, add:

    {provide: LocationStrategy, useClass: HashLocationStrategy}
  

Example (app.module.ts):

import { NgModule }       from '@angular/core';
import { BrowserModule  } from '@angular/platform-browser';
import { AppComponent }   from './app.component';
import { HashLocationStrategy, LocationStrategy } from '@angular/common';

@NgModule({
    declarations: [AppComponent],
    imports: [BrowserModule],
    providers: [{provide: LocationStrategy, useClass: HashLocationStrategy}],
    bootstrap: [AppComponent],
})
export class AppModule {}

Alternative

Use RouterModule.forRoot with the {useHash: true} argument.

Example:(from angular docs)

import { NgModule } from '@angular/core';
...

const routes: Routes = [//routes in here];

@NgModule({
  imports: [
    BrowserModule,
    FormsModule,
    RouterModule.forRoot(routes, { useHash: true })
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

I am old to the party but may be this will help some one. Thanks to @paperclip

In Windows 10:

Step 1: Go to This PC > Right click Properties

step 2: Click Advanced System Settings and click Environment Variables

Step 3: Under System Variables create new variable called HOME and input the value as %USERPROFILE% like below

Step 4: Important You must restart your PC to take effect

Step 5: Install Git for Windows now and optional Tortoise Git for windows if you prefer.

Make a git clone request or try pushing something in to your repo. Magic it will work. All should work fine now.

How about this?

#include <cstdio>

int main()
{
    unsigned int n = 1;
    char *p = 0;

    p = (char*)&n;
    if (*p == 1)
        std::printf("Little Endian\n");
    else 
        if (*(p + sizeof(int) - 1) == 1)
            std::printf("Big Endian\n");
        else
            std::printf("What the crap?\n");
    return 0;
}

You should start the WiFi activity from adb then simulate inputs:

adb shell am start -a android.intent.action.MAIN -n com.android.settings/.wifi.WifiSettings
adb shell input keyevent 20 && adb shell input keyevent 23

Here is the list of adb inputs: #7789826

I'm not sure if those keyevents are the right one for your case, but I think it will do. It simulated a "down" to select the first checkbox, then an "enter".

Though you already had the answer, thought to add some info.

As you mentioned Collections explicitly, you can't use listIterator to get the index for all types of collections.

List interfaces - ArrayList, LinkedList, Vector and Stack.

Has both iterator() and listIterator()

Set interfaces - HashSet, LinkedHashSet, TreeSet and EnumSet.

Has only iterator()

Map interfaces - HashMap, LinkedHashMap, TreeMap and IdentityHashMap

Has no iterators, but can be iterated using through the keySet() / values() or entrySet() as keySet() and entrySet() returns Set and values() returns Collection.

So its better to use iterators() with continuous increment of a value to get the current index for any collection type.

Although answer is provided I found simpler solution:

Date:

01/20/2017

By doing replace

CurrentDate = replace(date, "/", "-")

It will output:

01-20-2017

To delete all records from a table without deleting the table.

DELETE FROM table_name use with care, there is no undo!

To remove a table

DROP TABLE table_name

grep -nr search_string search_dir

will do a RECURSIVE (meaning the directory and all it's sub-directories) search for the search_string. (as correctly answered by usta).

The reason you were not getting any anwers with your friend's suggestion of:

grep -nr string

is because no directory was specified. If you are in the directory that you want to do the search in, you have to do the following:

grep -nr string .

It is important to include the '.' character, as this tells grep to search THIS directory.

Make sure you import MaterialModule as well since you are using md-input which does not belong to FormsModule

Well, there is no shortcut to do it as per my findings, but somehow you
an achieve it in few simple steps

First you have to declare a bean of type 'ProtobufJsonFormatHttpMessageConverter'

@Bean  
@Primary  
public ProtobufJsonFormatHttpMessageConverter protobufHttpMessageConverter() {  
  return new ProtobufJsonFormatHttpMessageConverter(JsonFormat.parser(), JsonFormat.printer());  
}  

Then you can just write an Utility class like ResponseBuilder, because it can parse the request by default but without these changes it can not produce Json response. and then you can write few methods to convert the response types to its related object type.

public static <T> T build(Message message, Class<T> type) {
  Printer printer = JsonFormat.printer();
  Gson gson = new Gson();
  try {
    return gson.fromJson(printer.print(message), type);
  } catch (JsonSyntaxException | InvalidProtocolBufferException e) {
    throw new ApiException(HttpStatus.INTERNAL_SERVER_ERROR, "Response   conversion Error", e);
  }
}

Then you can call this method from your controller class as last line like -

return ResponseBuilder.build(<returned_service_object>, <Type>);

Hope this will help you to implement protobuf in json format.

A const member is considered static by the compiler, as well as implying constant value semantics, which means references to the constant might be compiled into the using code as the value of the constant member, instead of a reference to the member.

In other words, a const member containing the value 10, might get compiled into code that uses it as the number 10, instead of a reference to the const member.

This is different from a static readonly field, which will always be compiled as a reference to the field.

Note, this is pre-JIT. When the JIT'ter comes into play, it might compile both these into the target code as values.

The thing that did the trick for me finally was to make sure that the owner/group were not root, but user:

chown -R ~/.ssh/ user
chgrp -R ~/.ssh/ user

In the following line

<form method="post" action="display()">

the action should be the name of your script and you should call the function, Something like this

<form method="post" action="yourFileName.php">
    <input type="text" name="studentname">
    <input type="submit" value="click" name="submit"> <!-- assign a name for the button -->
</form>

<?php
function display()
{
    echo "hello ".$_POST["studentname"];
}
if(isset($_POST['submit']))
{
   display();
} 
?>

Check to see if your user is mapped to the DB you are trying to log into.

    public class StructMain implements Serializable {
    public  int id;
    public String name;
    public String lastName;
}

this my item . implement Serializable and create ArrayList

ArrayList<StructMain> items =new ArrayList<>();

and put in Bundle

Bundle bundle=new Bundle();
bundle.putSerializable("test",items);

and create a new Intent that put Bundle to Intent

Intent intent=new Intent(ActivityOne.this,ActivityTwo.class);
intent.putExtras(bundle);
startActivity(intent);

for receive bundle insert this code

Bundle bundle = getIntent().getExtras();
ArrayList<StructMain> item = (ArrayList<StructMain>) bundle.getSerializable("test");

As far as I am aware, simply opening the file in write mode without append mode will erase the contents of the file.

ofstream file("filename.txt"); // Without append
ofstream file("filename.txt", ios::app); // with append

The first one will place the position bit at the beginning erasing all contents while the second version will place the position bit at the end-of-file bit and write from there.

I've used the implementation above and just now I came to know that it doesn't work on iPad running iOS 13. I had to add these lines before present() call in order to make it work

//avoiding to crash on iPad
if let popoverController = activityViewController.popoverPresentationController {
     popoverController.sourceRect = CGRect(x: UIScreen.main.bounds.width / 2, y: UIScreen.main.bounds.height / 2, width: 0, height: 0)
     popoverController.sourceView = self.view
     popoverController.permittedArrowDirections = UIPopoverArrowDirection(rawValue: 0)
}

That's how it works for me

func shareData(_ dataToShare: [Any]){

        let activityViewController = UIActivityViewController(activityItems: dataToShare, applicationActivities: nil)

        //exclude some activity types from the list (optional)
        //activityViewController.excludedActivityTypes = [
            //UIActivity.ActivityType.postToFacebook
        //]

        //avoiding to crash on iPad
        if let popoverController = activityViewController.popoverPresentationController {
            popoverController.sourceRect = CGRect(x: UIScreen.main.bounds.width / 2, y: UIScreen.main.bounds.height / 2, width: 0, height: 0)
            popoverController.sourceView = self.view
            popoverController.permittedArrowDirections = UIPopoverArrowDirection(rawValue: 0)
        }

        self.present(activityViewController, animated: true, completion: nil)
    }

The difference between a data flow diagram (DFD) and a flow chart (FC) are that a data flow diagram typically describes the data flow within a system and the flow chart usually describes the detailed logic of a business process.

You can also create a generic function to get the ID of the post, whether its outside or inside the loop (handles both the cases):

<?php

/**
 * @uses WP_Query
 * @uses get_queried_object()
 * @see get_the_ID()
 * @return int
 */
function get_the_post_id() {
  if (in_the_loop()) {
       $post_id = get_the_ID();
  } else {
       global $wp_query;
       $post_id = $wp_query->get_queried_object_id();
         }
  return $post_id;
} ?>

And simply do:

$page_id = get_the_post_id();

http://bluerobot.com/web/css/center1.html

body {
    margin:50px 0; 
    padding:0;
    text-align:center;
}

#Content {
    width:500px;
    margin:0 auto;
    text-align:left;
    padding:15px;
    border:1px dashed #333;
    background-color:#eee;
}

Sanitizing an Html document involves a lot of tricky things. This package maybe of help: https://github.com/mganss/HtmlSanitizer

As Johnathan Suggested, you would either want to save it in a cookie or a session.

The easier way would be to use a Session variable.

session_start();
if(!isset($_SESSION['org_referer']))
{
    $_SESSION['org_referer'] = $_SERVER['HTTP_REFERER'];
}

Put that at the top of the page, and you will always be able to access the first referer that the site visitor was directed by.

For everyone who looks example that works with Swift 2.2, Abizern code with modern do try catch handle of error

func databaseURL() -> NSURL? {

    let fileManager = NSFileManager.defaultManager()

    let urls = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)

    if let documentDirectory:NSURL = urls.first { // No use of as? NSURL because let urls returns array of NSURL
        // This is where the database should be in the documents directory
        let finalDatabaseURL = documentDirectory.URLByAppendingPathComponent("OurFile.plist")

        if finalDatabaseURL.checkResourceIsReachableAndReturnError(nil) {
            // The file already exists, so just return the URL
            return finalDatabaseURL
        } else {
            // Copy the initial file from the application bundle to the documents directory
            if let bundleURL = NSBundle.mainBundle().URLForResource("OurFile", withExtension: "plist") {

                do {
                    try fileManager.copyItemAtURL(bundleURL, toURL: finalDatabaseURL)
                } catch let error as NSError  {// Handle the error
                    print("Couldn't copy file to final location! Error:\(error.localisedDescription)")
                }

            } else {
                print("Couldn't find initial database in the bundle!")
            }
        }
    } else {
        print("Couldn't get documents directory!")
    }

    return nil
}

Update I've missed that new swift 2.0 have guard(Ruby unless analog), so with guard it is much shorter and more readable

func databaseURL() -> NSURL? {

let fileManager = NSFileManager.defaultManager()
let urls = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)

// If array of path is empty the document folder not found
guard urls.count != 0 else {
    return nil
}

let finalDatabaseURL = urls.first!.URLByAppendingPathComponent("OurFile.plist")
// Check if file reachable, and if reacheble just return path
guard finalDatabaseURL.checkResourceIsReachableAndReturnError(nil) else {
    // Check if file is exists in bundle folder
    if let bundleURL = NSBundle.mainBundle().URLForResource("OurFile", withExtension: "plist") {
        // if exist we will copy it
        do {
            try fileManager.copyItemAtURL(bundleURL, toURL: finalDatabaseURL)
        } catch let error as NSError { // Handle the error
            print("File copy failed! Error:\(error.localizedDescription)")
        }
    } else {
        print("Our file not exist in bundle folder")
        return nil
    }
    return finalDatabaseURL
}
return finalDatabaseURL 
}

Use Android Query library, very cool indeed.You can change it to use ProgressDialog as you see in other examples, this one will show progress view from your layout and hide it after completion.

File target = new File(new File(Environment.getExternalStorageDirectory(), "ApplicationName"), "tmp.pdf");
new AQuery(this).progress(R.id.progress_view).download(_competition.qualificationScoreCardsPdf(), target, new AjaxCallback<File>() {
    public void callback(String url, File file, AjaxStatus status) {
        if (file != null) {
            // do something with file  
        } 
    }
});

Try this: use "%40" in place of the "@"

If I were to paraphrase the question - is it possible to pick server context for query execution in the DDL - the answer is no. Only database context can be programmatically chosen with USE. (having already preselected the server context externally)

Linked server and OPEN QUERY can give access to the DDL but require somewhat a rewrite of your code to encapsulate as a string - making it difficult to develop/debug.

Alternately you could resort to an external driver program to pickup SQL files to send to the remote server via OPEN QUERY. However in most cases you might as well have connected to the server directly in the 1st place to evaluate the DDL.

Taken from another post

$checktable = mysql_query("SHOW TABLES LIKE '$this_table'");
$table_exists = mysql_num_rows($checktable) > 0;

In my case I had to uninstall and reinstall the wireless adapter driver to be able to execute the command

char* str = "HELLO";
char c = str[1];

Keep in mind that arrays and strings in C begin indexing at 0 rather than 1, so "H" is str[0], "E" is str[1], the first "L" is str[2] and so on.

 MarginLayoutParams layoutParams = (MarginLayoutParams) getLayoutParams();
 layoutParams.setMargins(leftMargin, topMargin, rightMargin, bottomMargin);

Since Result Set is an interface, When you obtain a reference to a ResultSet through a JDBC call, you are getting an instance of a class that implements the ResultSet interface. This class provides concrete implementations of all of the ResultSet methods.

Interfaces are used to divorce implementation from, well, interface. This allows the creation of generic algorithms and the abstraction of object creation. For example, JDBC drivers for different databases will return different ResultSet implementations, but you don't have to change your code to make it work with the different drivers

In very short, if your ResultSet contains result, then using rs.next return true if you have recordset else it returns false.

<Link to="/page">
    <Box sx={{ display: 'inline-block' }}>
        <PLink variant="primary">Page</PLink>
    </Box>
</Link>

In some cases when using another component inside the Gatsby <Link> component, adding a div with display: 'inline-block' around the inner component, prevents underlining (of 'Page' in the example).

Before using v-html, you have to make sure that the element which you escape is sanitized in case you allow user input, otherwise you expose your app to xss vulnerabilities.

More info here: https://vuejs.org/v2/guide/security.html

I highly encourage you that instead of using v-html to use this npm package

Overly simplified here, but Func is a machine, whereas Expression is a blueprint. :D

If anyone ever gets this far down, I spent some time hacking on this trying to patch moment.js (https://github.com/moment/moment). Here's something that I took away from it:

function isNumeric(val) {
    var _val = +val;
    return (val !== val + 1) //infinity check
        && (_val === +val) //Cute coercion check
        && (typeof val !== 'object') //Array/object check
}

Handles the following cases:

True! :

isNumeric("1"))
isNumeric(1e10))
isNumeric(1E10))
isNumeric(+"6e4"))
isNumeric("1.2222"))
isNumeric("-1.2222"))
isNumeric("-1.222200000000000000"))
isNumeric("1.222200000000000000"))
isNumeric(1))
isNumeric(0))
isNumeric(-0))
isNumeric(1010010293029))
isNumeric(1.100393830000))
isNumeric(Math.LN2))
isNumeric(Math.PI))
isNumeric(5e10))

False! :

isNumeric(NaN))
isNumeric(Infinity))
isNumeric(-Infinity))
isNumeric())
isNumeric(undefined))
isNumeric('[1,2,3]'))
isNumeric({a:1,b:2}))
isNumeric(null))
isNumeric([1]))
isNumeric(new Date()))

Ironically, the one I am struggling with the most:

isNumeric(new Number(1)) => false

Any suggestions welcome. :]

In your terminal run: docker exec -it container_name /bin/bash Then: mysql

For italic you can use the 'i' tag, for bold try the 'b' tag

    <i> italic </i>_x000D_
    <b> bold </b>

This is similar to the answer I posted on: Preview a Git push

Drop these functions into your Bash profile:

• gbout - git branch outgoing
• gbin - git branch incoming

You can use this like:

• If on master: gbin branch1 <-- this will show you what's in branch1 and not in master
• If on master: gbout branch1 <-- this will show you what's in master that's not in branch 1

This will work with any branch.

function parse_git_branch {
  git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'
}

function gbin {
    echo branch \($1\) has these commits and \($(parse_git_branch)\) does not
    git log ..$1 --no-merges --format='%h | Author:%an | Date:%ad | %s' --date=local
}

function gbout {
    echo branch \($(parse_git_branch)\) has these commits and \($1\) does not
    git log $1.. --no-merges --format='%h | Author:%an | Date:%ad | %s' --date=local
}

What about:

//true if it doesn't contain letters
bool result = hello.Any(x => !char.IsLetter(x));

I had the same problem, I can't figured out how to find the aliases used by Git Bash on Windows. After searching for a while, I found the aliases.sh file under C:\Program Files\Git\etc\profile.d\aliases.sh.

This is the path under windows 7, maybe can be different in other installation.

Just open it with your preferred editor in admin mode. After save it, reload your command prompt.

I hope this can help!

Full version:

<? echo date('F Y'); ?>

Short version:

<? echo date('M Y'); ?>

Here is a good reference for the different date options.

update

To show the previous month we would have to introduce the mktime() function and make use of the optional timestamp parameter for the date() function. Like this:

echo date('F Y', mktime(0, 0, 0, date('m')-1, 1, date('Y')));

This will also work (it's typically used to get the last day of the previous month):

echo date('F Y', mktime(0, 0, 0, date('m'), 0, date('Y')));

Hope that helps.

there is no standard, but most frameworks support both, you can see for example for java spring that it accepts both here

@GetMapping("/api/foos")
@ResponseBody
public String getFoos(@RequestParam List<String> id) {
    return "IDs are " + id;
}

And Spring MVC will map a comma-delimited id parameter:

http://localhost:8080/api/foos?id=1,2,3
----
IDs are [1,2,3]

Or a list of separate id parameters:

http://localhost:8080/api/foos?id=1&id=2
----
IDs are [1,2]

If running

source ~/.bashrc

results in "No such file or directory"

On windows:

1. Go to c/Users/
2. While holding shift, right-click .bashrc file and select "Copy as path"
3. In bash: source <pasteCopiedPathHere> -> for example: source "C:\Users\John\.bashhrc"

if your css file in public/css use :

<link rel="stylesheet" type="text/css" href="{{ asset('css/style.css') }}" >

if your css file in another folder in public use :

 <link rel="stylesheet" type="text/css" href="{{ asset('path/css/style.css') }}" >

Try : http://localhost/phpmyadmin/

Use lowercase letters and try again

SELECT * FROM table WHERE arr && '{s}'::text[];

Compare two arrays for containment.

You can do this using javascript. No need for Jquery or Regex

function isNumeric(n) {
  return !isNaN(parseFloat(n)) && isFinite(n);
}

While implementing

var val = $('yourinputelement').val();
if(isNumeric(val)) { alert('number'); } 
else { alert('not number'); }

Update: To check if a string has numbers in them, you can use regular expressions to do that

var matches = val.match(/\d+/g);
if (matches != null) {
    alert('number');
}

AlliterativeAlice's example helped me tremendously. In my case, though, the server I was talking to didn't like having single quotes around utf-8 in the content type. It failed with a generic "Server Error" and it took hours to figure out what it didn't like:

request.ContentType = "text/xml; encoding=utf-8";

Unexpected 'O' error is thrown when JSON data or String happens to get parsed.

If it's string, it's already stringfied. Parsing ends up with Unexpected 'O' error.

I faced similar( although in different context), I solved the following error by removing JSON Producer.

    @POST
    @Produces({ **MediaType.APPLICATION_JSON**})
    public Response login(@QueryParam("agentID") String agentID , Officer aOffcr ) {
      return Response.status(200).entity("OK").build();

  }

The response contains "OK" string return. The annotation marked as @Produces({ **MediaType.APPLICATION_JSON})** tries to parse the string to JSON format which results in Unexpected 'O'.

Removing @Produces({ MediaType.APPLICATION_JSON}) works fine. Output : OK

Beware: Also, on client side, if you make ajax request and use JSON.parse("OK"), it throws Unexpected token 'O'

O is the first letter of the string

JSON.parse(object) compares with jQuery.parseJSON(object);

JSON.parse('{ "name":"Yergalem", "city":"Dover"}'); --- Works Fine

Try the following:

RewriteEngine on 
RewriteCond %{HTTP_REFERER} !^http://(www\.)?localhost [NC] 
RewriteCond %{HTTP_REFERER} !^http://(www\.)?localhost.*$ [NC] 
RewriteRule \.(gif|jpg)$ - [F]

Returns 403, if you access images directly, but allows them to be displayed on site.

Note: It is possible that when you open some page with image and then copy that image's path into the address bar you can see that image, it is only because of the browser's cache, in fact that image has not been loaded from the server (from Davo, full comment below).

it worked for me..

countries.results= $.grep(countries.results, function (e) { 
      if(e.id!= currentID) {
       return true; 
      }
     });

//I think its simple like

#include<stdio.h>
int main()

{
int a1[100],a2[100],i,t,l1,l2,n;
printf("Enter the number of elements:\n");
scanf("%d",&n);
printf("Enter the elements:\n");
for(i=0;i<n;i++)
{
    scanf("%d",&a1[i]);
}
l1=a1[0];
for(i=0;i<n;i++)
{
    if(a1[i]>=l1)
    {
        l1=a1[i];
        t=i;
    }
}
for(i=0;i<(n-1);i++)
{
    if(i==t)
    {
        continue;
    }
    else
    {
        a2[i]=a1[i];
    }
}
l2=a2[0];
for(i=1;i<(n-1);i++)
{
    if(a2[i]>=l2 && a2[i]<l1)
    {
        l2=a2[i];
    }
}
printf("Second highest number is %d",l2);
return 0;
}

ax.set_title() should set the titles for separate subplots:

import matplotlib.pyplot as plt

if __name__ == "__main__":
    data = [1, 2, 3, 4, 5]

    fig = plt.figure()
    fig.suptitle("Title for whole figure", fontsize=16)
    ax = plt.subplot("211")
    ax.set_title("Title for first plot")
    ax.plot(data)

    ax = plt.subplot("212")
    ax.set_title("Title for second plot")
    ax.plot(data)

    plt.show()

Can you check if this code works for you? Maybe something overwrites them later?

It's all down to how calls to objects are handled, and how much protection they need. COM objects can ask the runtime to protect them against being called by multiple threads at the same time; those that don't can potentially be called concurrently from different threads, so they have to protect their own data.

In addition, it's also necessary for the runtime to prevent a COM object call from blocking the user interface, if a call is made from a user interface thread.

An apartment is a place for objects to live, and they contain one or more threads. The apartment defines what happens when calls are made. Calls to objects in an apartment will be received and processed on any thread in that apartment, with the exception that a call by a thread already in the right apartment is processed by itself (i.e. a direct call to the object).

Threads can be either in a Single-Threaded Apartment (in which case they are the only thread in that apartment) or in a Multi-Threaded Apartment. They specify which when the thread initializes COM for that thread.

The STA is primarily for compatibility with the user interface, which is tied to a specific thread. An STA receives notifications of calls to process by receiving a window message to a hidden window; when it makes an outbound call, it starts a modal message loop to prevent other window messages being processed. You can specify a message filter to be called, so that your application can respond to other messages.

By contrast all MTA threads share a single MTA for the process. COM may start a new worker thread to handle an incoming call if no threads are available, up to a pool limit. Threads making outbound calls simply block.

For simplicity we'll consider only objects implemented in DLLs, which advertise in the registry what they support, by setting the ThreadingModel value for their class's key. There are four options:

• Main thread (ThreadingModel value not present). The object is created on the host's main UI thread, and all calls are marshalled to that thread. The class factory will only be called on that thread.
• Apartment. This indicates that the class can run on any single-threaded-mode thread. If the thread that creates it is an STA thread, the object will run on that thread, otherwise it will be created in the main STA - if no main STA exists, an STA thread will be created for it. (This means MTA threads that create Apartment objects will be marshalling all calls to a different thread.) The class factory can be called concurrently by multiple STA threads so it must protect its internal data against this.
• Free. This indicates a class designed to run in the MTA. It will always load in the MTA, even if created by an STA thread, which again means the STA thread's calls will be marshalled. This is because a Free object is generally written with the expectation that it can block.
• Both. These classes are flexible and load in whichever apartment they're created from. They must be written to fit both sets of requirements, however: they must protect their internal state against concurrent calls, in case they're loaded in the MTA, but must not block, in case they're loaded in an STA.

From the .NET Framework, basically just use [STAThread] on any thread that creates UI. Worker threads should use the MTA, unless they're going to use Apartment-marked COM components, in which case use the STA to avoid marshalling overhead and scalability problems if the same component is called from multiple threads (as each thread will have to wait for the component in turn). It's much easier all around if you use a separate COM object per thread, whether the component is in the STA or MTA.

Considering filter:expression is a Microsoft extension to CSS, so it will only work in Internet Explorer. If you want to grey it out, I would recommend that you set it's opacity to 50% using a bit of javascript.

http://lyxus.net/mv would be a good place to start, because it discusses an opacity script that works with Firefox, Safari, KHTML, Internet Explorer and CSS3 capable browsers.

You might also want to give it a grey border.

You can also run the PHP script as daemon or cronjob: #!/usr/bin/php -q

HTH,

I suggest doing it in two steps:

# set fixed value to 'c2' where the condition is met
df.loc[df['c1'] == 'Value', 'c2'] = 10

# copy value from 'c3' to 'c2' where the condition is NOT met
df.loc[df['c1'] != 'Value', 'c2'] = df[df['c1'] != 'Value', 'c3']

I know this has already been answered, but I wanted to share a potentially better looking way to call Popen via the use of from x import x and functions:

from subprocess import PIPE, Popen


def cmdline(command):
    process = Popen(
        args=command,
        stdout=PIPE,
        shell=True
    )
    return process.communicate()[0]

print cmdline("cat /etc/services")
print cmdline('ls')
print cmdline('rpm -qa | grep "php"')
print cmdline('nslookup google.com')

Just append() the text nodes:

$('#replyBox').append(quote);

That is not possible bro, Laravel assumes everything is in public folder.

So my suggestion is:

1. Go to the public folder.
2. Create a folder, preferably named css.
3. Create the folder for the respective views to make things organized.
4. Put the respective css inside of those folders, that would be easier for you.

Or

If you really insist to put css inside of views folder, you could try creating Symlink (you're mac so it's ok, but for windows, this will only work for Vista, Server 2008 or greater) from your css folder directory to the public folder and you can use {{HTML::style('your_view_folder/myStyle.css')}} inside of your view files, here's a code for your convenience, in the code you posted, put these before the return View::make():

$css_file = 'myStyle.css';
$folder_name = 'your_view_folder';
$view_path = app_path() . '/views/' . $folder_name . '/' . $css_file;
$public_css_path = public_path() . '/' . $folder_name;
if(file_exists($public_css_path)) exec('rm -rf ' . $public_css_path);
exec('mkdir ' . $public_css_path);
exec('ln -s ' . $view_path .' ' . $public_css_path . '/' . $css_file);

If you really want to try doing your idea, try this:

<link rel="stylesheet" href="<?php echo app_path() . 'views/your_view_folder/myStyle.css'?>" type="text/css">

But it won't work even if the file directory is correct because Laravel won't do that for security purposes, Laravel loves you that much.

I have the same problem, and I have add this code to my application and its work fine for me.

step -1 : added the jquery.placeholder.js plugin

step -2 :write the below code in your area.

$(function () {
       $('input, textarea').placeholder();
});

And now I can see placeholders on the input boxes!

I think this is what you want, I already tested this code and works

The tools used are: (all these tools can be downloaded as Nuget packages)

http://fluentassertions.codeplex.com/

http://autofixture.codeplex.com/

http://code.google.com/p/moq/

https://nuget.org/packages/AutoFixture.AutoMoq

var fixture = new Fixture().Customize(new AutoMoqCustomization());
var myInterface = fixture.Freeze<Mock<IFileConnection>>();

var sut = fixture.CreateAnonymous<Transfer>();

myInterface.Setup(x => x.Get(It.IsAny<string>(), It.IsAny<string>()))
        .Throws<System.IO.IOException>();

sut.Invoking(x => 
        x.TransferFiles(
            myInterface.Object, 
            It.IsAny<string>(), 
            It.IsAny<string>()
        ))
        .ShouldThrow<System.IO.IOException>();

Edited:

Let me explain:

When you write a test, you must know exactly what you want to test, this is called: "subject under test (SUT)", if my understanding is correctly, in this case your SUT is: Transfer

So with this in mind, you should not mock your SUT, if you substitute your SUT, then you wouldn't be actually testing the real code

When your SUT has external dependencies (very common) then you need to substitute them in order to test in isolation your SUT. When I say substitute I'm referring to use a mock, dummy, mock, etc depending on your needs

In this case your external dependency is IFileConnection so you need to create mock for this dependency and configure it to throw the exception, then just call your SUT real method and assert your method handles the exception as expected

• var fixture = new Fixture().Customize(new AutoMoqCustomization());: This linie initializes a new Fixture object (Autofixture library), this object is used to create SUT's without having to explicitly have to worry about the constructor parameters, since they are created automatically or mocked, in this case using Moq

• var myInterface = fixture.Freeze<Mock<IFileConnection>>();: This freezes the IFileConnection dependency. Freeze means that Autofixture will use always this dependency when asked, like a singleton for simplicity. But the interesting part is that we are creating a Mock of this dependency, you can use all the Moq methods, since this is a simple Moq object

• var sut = fixture.CreateAnonymous<Transfer>();: Here AutoFixture is creating the SUT for us

• myInterface.Setup(x => x.Get(It.IsAny<string>(), It.IsAny<string>())).Throws<System.IO.IOException>(); Here you are configuring the dependency to throw an exception whenever the Get method is called, the rest of the methods from this interface are not being configured, therefore if you try to access them you will get an unexpected exception

• sut.Invoking(x => x.TransferFiles(myInterface.Object, It.IsAny<string>(), It.IsAny<string>())).ShouldThrow<System.IO.IOException>();: And finally, the time to test your SUT, this line uses the FluenAssertions library, and it just calls the TransferFiles real method from the SUT and as parameters it receives the mocked IFileConnection so whenever you call the IFileConnection.Get in the normal flow of your SUT TransferFiles method, the mocked object will be invoking throwing the configured exception and this is the time to assert that your SUT is handling correctly the exception, in this case, I am just assuring that the exception was thrown by using the ShouldThrow<System.IO.IOException>() (from the FluentAssertions library)

This is a late answer, but by looking at the source code, I noticed that when the video is fullscreen, the "mejs-container-fullscreen" class is added to the "mejs-container" element. It is thus possible to change the styling based on this class.

.mejs-container.mejs-container-fullscreen {
    // This rule applies only to the container when in fullscreen
    padding-top: 57%;
}

Also, if you wish to make your MediaElement video fluid using CSS, below is a great trick by Chris Coyier: http://css-tricks.com/rundown-of-handling-flexible-media/

Just add this to your CSS:

.mejs-container {
    width: 100% !important;
    height: auto !important;
    padding-top: 57%;
}
.mejs-overlay, .mejs-poster {
    width: 100% !important;
    height: 100% !important;
}
.mejs-mediaelement video {
    position: absolute;
    top: 0; left: 0; right: 0; bottom: 0;
    width: 100% !important;
    height: 100% !important;
}

I hope it helps.

This is a ternary operator, it's basically an inline if statement

x ? y : z

works like

if(x) y else z

except, instead of statements you have expressions; so you can use it in the middle of a more complex statement.

It's useful for writing succinct code, but can be overused to create hard to maintain code.

Most of the time I just wish to have all placeholders equal to the verbose name of the field defined in my models

I've added a mixin to easily do this to any form that I create,

class ProductForm(PlaceholderMixin, ModelForm):
    class Meta:
        model = Product
        fields = ('name', 'description', 'location', 'store')

And

class PlaceholderMixin:
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        field_names = [field_name for field_name, _ in self.fields.items()]
        for field_name in field_names:
            field = self.fields.get(field_name)
            field.widget.attrs.update({'placeholder': field.label})

Both the .ordinal() and values()[i] are unstable since they are dependent to the order of enums. Thus if you change the order of enums or add/delete some your program would break.

Here is a simple yet effective method to map between enum and int.

public enum Action {
    ROTATE_RIGHT(0), ROTATE_LEFT(1), RIGHT(2), LEFT(3), UP(4), DOWN(5);

    public final int id;
    Action(int id) {
        this.id = id;
    }

    public static Action get(int id){
        for (Action a: Action.values()) {
            if (a.id == id)
                return a;
        }
        throw new IllegalArgumentException("Invalid id");
    }
}

Applying it for strings shouldn't be difficult.

Another option is to change the version number in the packages.config file. This will cause NuGet to download the dlls for that version the next time you build.

If you are not using model-first; Double click 'edmx' file ->select all and delete all entity models -> save -> right click 'update model from database ->select required tables ->finish and save.

If you want to select a value based on true / false use

[selected]="opt.selected == true"

 <option *ngFor="let opt of question.options" [value]="opt.key" [selected]="opt.selected == true">{{opt.selected+opt.value}}</option>

Angular 2 - Setting selected value on dropdown list

That's because that's an SQL function, not PHP. You can use PDO::lastInsertId().

Like:

$stmt = $db->prepare("...");
$stmt->execute();
$id = $db->lastInsertId();

If you want to do it with SQL instead of the PDO API, you would do it like a normal select query:

$stmt = $db->query("SELECT LAST_INSERT_ID()");
$lastId = $stmt->fetchColumn();

1. Select the project
2. Right click on the selected Project
3. Team -> Cleanup

Problem Solved.

Note: The Above steps will work only Eclipse(Indigo package)

With this one line you can disable any input field in a form

$('form *').prop('disabled', true);

If you use Babel, you can already use the optional chaining syntax with @babel/plugin-proposal-optional-chaining Babel plugin. This would allow you to replace this:

console.log(a && a.b && a.b.c);

with this:

console.log(a?.b?.c);

A bit verbose but this is how I do it:

@click="$emit('click', $event)"

UPDATE: Example added by @sparkyspider

<div-container @click="doSomething"></div-container>

In div-container component...

<template>
  <div @click="$emit('click', $event);">The inner div</div>
</template>

In this line:

for name, email, lastname in unpaidMembers.items():

unpaidMembers.items() must have only two values per iteration.

Here is a small example to illustrate the problem:

This will work:

for alpha, beta, delta in [("first", "second", "third")]:
    print("alpha:", alpha, "beta:", beta, "delta:", delta)

This will fail, and is what your code does:

for alpha, beta, delta in [("first", "second")]:
    print("alpha:", alpha, "beta:", beta, "delta:", delta)

In this last example, what value in the list is assigned to delta? Nothing, There aren't enough values, and that is the problem.

make sure that you do not have defined setter for the for your primary key in model class.

public class User{
@Id
@GeneratedValues
private int user_Id;
private String userName;

public int getUser_Id{
return user_Id;
}

public String getUserName{
return userName;
}

public void setUserName{
this.userName=userName;
}
}

Here's a really hacky way to do it in *nix, you'll get some stuff you don't really care about (ie: warnings::register etc), but it should give you a list of every .pm file that's accessible via perl.

for my $path (@INC) {
    my @list = `ls -R $path/**/*.pm`;
    for (@list) {
        s/$path\///g;
        s/\//::/g;
        s/\.pm$//g;
        print;
    }
}

You try and compare pointers here, not the contents of what is pointed to (ie, your characters).

You must use either memcmp or str{,n}cmp to compare the contents.

Dim strFirstAddress As String
Dim searchlast As Range
Dim search As Range

Set search = ActiveSheet.Range("A1:A100")
Set searchlast = search.Cells(search.Cells.Count)

Set rngFindValue = ActiveSheet.Range("A1:A100").Find(Text, searchlast, xlValues)
If Not rngFindValue Is Nothing Then
  strFirstAddress = rngFindValue.Address
  Do
    Set rngFindValue = search.FindNext(rngFindValue)
  Loop Until rngFindValue.Address = strFirstAddress

Found out these problems can be addressed by using

ObjectMapper#convertValue(Object fromValue, Class<T> toValueType)

As a result, the origal quuestion can be solved in a 2-step converison:

1. Demarshall the JSON back to an object - in which the Map<String, Object> is demarshalled as a HashMap<String, LinkedHashMap>, by using bjectMapper#readValue().

2. Convert inner LinkedHashMaps back to proper objects

ObjectMapper mapper = new ObjectMapper(); Class clazz = (Class) Class.forName(classType); MyOwnObject value = mapper.convertValue(value, clazz);

To prevent the 'classType' has to be known in advance, I enforced during marshalling an extra Map was added, containing <key, classNameString> pairs. So at unmarshalling time, the classType can be extracted dynamically.

simply use "$last_id = mysqli_insert_id($conn);"

Its realy simple to add multilanguage in myphpadmin if you got garbdata showing in myphpadmin, just go to myphpadmin click your database go to operations tab in operation tab page see collation section set it to utf8_general_ci, after that all your garbdata will show correctly. a simple and easy trick

You can try this line of code:

pdDataFrame = pd.DataFrame([np.nan] * 7)

This will create a pandas dataframe of size 7 with NaN of type float:

if you print pdDataFrame the output will be:

     0
0   NaN
1   NaN
2   NaN
3   NaN
4   NaN
5   NaN
6   NaN

Also the output for pdDataFrame.dtypes is:

0    float64
dtype: object

Create New Project and Import all files to the new project.it worked for me....

I found that the following is useful if you need the return value:

result = %x[ls]
puts result

I specifically wanted to list the pids of all the Java processes on my machine, and used this:

ids = %x[ps ax | grep java | awk '{ print $1 }' | xargs]

ToString() Vs Convert.ToString()

Similarities :-

Both are used to convert a specific type to string i.e int to string, float to string or an object to string.

Difference :-

ToString() can't handle null while in case with Convert.ToString() will handle null value.

Example :

namespace Marcus
{
    class Employee
    {
        public int Id { get; set; }
        public string Name { get; set; }
    }
    class Startup
    {
        public static void Main()
        {
            Employee e = new Employee();
            e = null;

            string s = e.ToString(); // This will throw an null exception
            s = Convert.ToString(e); // This will throw null exception but it will be automatically handled by Convert.ToString() and exception will not be shown on command window.
        }
    }
}

In my case mongodb packages are named mongodb-org and mongodb-org-*

So when I type sudo apt purge mongo then tab (for auto-completion) I can see all installed packages that start with mongo.

Another option is to run the following command (which will list all packages that contain mongo in their names or their descriptions):

dpkg -l | grep mongo

In summary, I would do (to purge all packages that start with mongo):

sudo apt purge mongo*

and then (to make sure that no mongo packages are left):

dpkg -l | grep mongo

Of course, as mentioned by @alicanozkara, you will need to manually remove some directories like /var/log/mongodb and /var/lib/mongodb

Running the following find commands:

sudo find /etc/ -name "*mongo*" and sudo find /var/ -name "*mongo*"

may also show some files that you may want to remove, like:

/etc/systemd/system/mongodb.service
/etc/apt/sources.list.d/mongodb-org-3.2.list

and:

/var/lib/apt/lists/repo.mongodb.*

You may also want to remove user and group mongodb, to do so you need to run:

sudo userdel -r mongodb
sudo groupdel mongodb

To check whether mongodb user/group exists or not, try:

cut -d: -f1 /etc/passwd | grep mongo
cut -d: -f1 /etc/group | grep mongo

The sshpass utility is meant for exactly this. First, install sshpass by typing this command:

sudo apt-get install sshpass

Then prepend your ssh/scp command with

sshpass -p '<password>' <ssh/scp command>

This program is easiest to install when using Linux.

User should consider using SSH's more secure public key authentication (with the ssh command) instead.

If you are targeting SDK > 21 (lollipop or 5.0) use

context.getDrawable(R.drawable.your_drawable_name)

See docs

It's really easy:

myList.Clear();

The one True answer is to not use the select field (if you need to do something when you re-select same answer.)

Create a dropdown menu with conventional div, button, show/hide menu. Link: https://www.w3schools.com/howto/howto_js_dropdown.asp

Could have been avoided had one been able to add event listeners to options. If there had been an onSelect listener for select element. And if clicking on the select field didn't aggravatingly fire off mousedown, mouseup, and click all at the same time on mousedown.

If you press admin on a private repo and scroll down to the part about pages, it writes that it'll be public. I'll check later if .htaccess control or similar is possible, but I don't have much hope for it.

The problem is that when redirecting a file into 'mail' like that, it's used for the message body only. Any headers you embed in the file will go into the body instead.

Try:

mail --append="Content-type: text/html" -s "Built notification" [email protected] < /var/www/report.csv

--append lets you add arbitrary headers to the mail, which is where you should specify the content-type and content-disposition. There's no need to embed the To and Subject headers in your file, or specify them with --append, since you're implicitly setting them on the command line already (-s is the subject, and [email protected] automatically becomes the To).

The link you gave does actually describe the differences, but it's buried at the bottom of the page:

http://www.cplusplus.com/reference/cstdio/fopen/

Text files are files containing sequences of lines of text. Depending on the environment where the application runs, some special character conversion may occur in input/output operations in text mode to adapt them to a system-specific text file format. Although on some environments no conversions occur and both text files and binary files are treated the same way, using the appropriate mode improves portability.

The conversion could be to normalize \r\n to \n (or vice-versa), or maybe ignoring characters beyond 0x7F (a-la 'text mode' in FTP). Personally I'd open everything in binary-mode and use a good text-encoding library for dealing with text.

Use below command in Debian based container:

apt-get install vim-tiny

Complete instruction for using in Dockerfile:

RUN apt-get update && apt-get install --no-install-recommends -y \   
 vim-tiny \  
 && apt-get clean && rm -rf /var/lib/apt/lists/*

It doesn't install unnecessary packages and removes unnecessary downloaded files, so your docker image size won't increase dramatically.

With current browsers (this question is dating a bit now), you can use the much simpler vw (viewport width) unit:

#help_panel {
  margin-left: calc(50% - 50vw);
  width: 100vw;
}

(usage data: http://caniuse.com/#feat=viewport-units)

From my tests, this should not break your flow while being easy to use.

Use security.ignored property:

security.ignored=/**

security.basic.enable: false will just disable some part of the security auto-configurations but your WebSecurityConfig still will be registered.

There is a default security password generated at startup

Try to Autowired the AuthenticationManagerBuilder:

@Override
@Autowired
protected void configure(AuthenticationManagerBuilder auth) throws Exception { ... }

Ids are supposed to be unique document wide, so you shouldn't have to select based on both. You can assign an element multiple classes though with class="class1 class2"

You can disable the event by applying following code:

with .attr() API

$('#your_id').attr("disabled", "disabled");

or with .prop() API

$('#your_id').prop('disabled', true);

You can use literal:

this.Controls.Add(new LiteralControl("<script type='text/javascript'>myFunction();</script>"));

Delegate and Live are easy to use but if you won't have any more li:s added dynamically you could use event delagation with normal bind/click as well. There should be some performance gain using this method since the DOM won't have to be monitored for new matching elements. Haven't got any actual numbers but it makes sense :)

$("#wizard").click(function (e) {
    var source = $(e.target);
    if(source.is("li")){
        // alert index of li relative to ul parent
        alert(source.index());
    }
});

You could test it at jsFiddle: http://jsfiddle.net/jimmysv/4Sfdh/1/

I've found the same thing, but only on emulators that have the Use Host GPU setting ticked. Try turning that off, you'll no longer see those warnings (and the emulator will run horribly, horribly slowly..)

In my experience those warnings are harmless. Notice that the "error" is EGL_SUCCESS, which would seem to indicate no error at all!

def f(dic):
    if 'a' in dic:
        print dic['a'],
        pass
    else: print 'None',

    if 'b' in dic:
        print dic['b'],
        pass
    else: print 'None',

    if 'c' in dic:
        print dic['c'],
        pass
    else: print 'None',
    print
    pass
f({})
f({'a':20,
   'c':30})
f({'a':20,
   'c':30,
   'b':'red'})
____________

the above code will output

None None None
20 None 30
20 red 30

This is as good as passing variable arguments by means of a dictionary

What I do when it happens is Disable the COM port into the Device Manager and Enable it again.

It stop the communications with another program or thread and become free for you.

I hope this works for you. Regards.

Solution

$userName = 'test-domain\test-login'
$password = 'test-password'

$pwdSecureString = ConvertTo-SecureString -Force -AsPlainText $password
$credential = New-Object -TypeName System.Management.Automation.PSCredential `
    -ArgumentList $userName, $pwdSecureString

For Build Machines
In the previous code replace user name and password values by secret ("hidden from logs") environment variables of your build-machine

Test results by

'# Results'
$credential.GetNetworkCredential().Domain
$credential.GetNetworkCredential().UserName
$credential.GetNetworkCredential().Password

and you'll see

# Results
test-domain
test-login
test-password

There is a mysql2sqlite.sh script on GitHub

As described in the header, the script can be used like this:

./mysql2sqlite.sh myDbase | sqlite3 database.sqlite

alternatives

• an updated version https://github.com/dumblob/mysql2sqlite
• A simpler script was posted at the the MySQL Forums

val array2 = array :+ 4
//Array(1, 2, 3, 4)

Works also "reversed":

val array2 = 4 +: array
Array(4, 1, 2, 3)

There is also an "in-place" version:

var array = Array( 1, 2, 3 )
array +:= 4
//Array(4, 1, 2, 3)
array :+= 0
//Array(4, 1, 2, 3, 0)

Data:

parent_list = [{'A': 'val1', 'B': 'val2'}, {'C': 'val3', 'D': 'val4'}]

in Jinja2 iteration:

{% for dict_item in parent_list %}
   {% for key, value in dict_item.items() %}
      <h1>Key: {{key}}</h1>
      <h2>Value: {{value}}</h2>
   {% endfor %}
{% endfor %}

Note:

Make sure you have the list of dict items. If you get UnicodeError may be the value inside the dict contains unicode format. That issue can be solved in your views.py. If the dict is unicode object, you have to encode into utf-8.

This error message probably means that you either mistyped the server name or forgot to start an ssh server at server. Make absolutely certain that an ssh server is running on the server at port 22, and that it's not firewalled. You can test that with ssh user@server.

try this

background-image: url("/yourimagefolder/yourimage.jpg"); 

I had the same problem when I used background-image: url("yourimagefolder/yourimage.jpg");

Notice the slash that made the difference. The level of the folder was the reason why I could not load the image. I guess you also encountered the same issue

A previous poster said..

If you have PHP installed as a command line tool… your shebang (#!) line needs to look like this: #!/usr/bin/php

While this could be true… just because you can type in php does NOT necessarily mean that's where php is going to be... /usr/bin/php is A common location… but as with any shebang… it needs to be tailored to YOUR env.

a quick way to find out WHERE YOUR particular executable is located on your $PATH, try.. ?which -a php ENTER, which for me looks like..

php is /usr/local/php5/bin/php
php is /usr/bin/php
php is /usr/local/bin/php
php is /Library/WebServer/CGI-Executables/php

The first one is the default i'd get if I just typed in php at a command prompt… but I can use any of them in a shebang, or directly… You can also combine the executable name with env, as is often seen, but I don't really know much about / trust that. XOXO.

There's no one answer. The standard defines minimum ranges. An int must be able to hold at least 65535. Most modern compilers however allow ints to be 32-bit values. Additionally, there's nothing preventing multiple types from having the same capacity (e.g. int and long).

That being said, the standard does say in your particular case:

0 ? +18446744073709551615

as the range for unsigned long long int.

You need to set the binding context of the ToolStripComboBox.ComboBox.

Here is a slightly modified version of the code that I have just recreated using Visual Studio. The menu item combo box is called toolStripComboBox1 in my case. Note the last line of code to set the binding context.

I noticed that if the combo is in the visible are of the toolstrip, the binding works without this but not when it is in a drop-down. Do you get the same problem?

If you can't get this working, drop me a line via my contact page and I will send you the project. You won't be able to load it using SharpDevelop but will with C# Express.

var languages = new string[2];
languages[0] = "English";
languages[1] = "German";

DataSet myDataSet = new DataSet();

// --- Preparation
DataTable lTable = new DataTable("Lang");
DataColumn lName = new DataColumn("Language", typeof(string));
lTable.Columns.Add(lName);

for (int i = 0; i < languages.Length; i++)
{
    DataRow lLang = lTable.NewRow();
    lLang["Language"] = languages[i];
    lTable.Rows.Add(lLang);
}
myDataSet.Tables.Add(lTable);

toolStripComboBox1.ComboBox.DataSource = myDataSet.Tables["Lang"].DefaultView;
toolStripComboBox1.ComboBox.DisplayMember = "Language";

toolStripComboBox1.ComboBox.BindingContext = this.BindingContext;

I'm in the same situation as you and the solution I found for cleaning the data is deleting all the CoreData stuff that my view controllers rely on to draw it's info. But I still found this approach to be very bad, I think that a more elegant way to do this can be accomplished without storyboards and using only code to manage the transitions between view controllers.

I've found this project at Github that does all this stuff only by code and it's quite easy to understand. They use a Facebook-like side menu and what they do is change the center view controller depending if the user is logged-in or not. When the user logs out the appDelegate removes the data from CoreData and sets the main view controller to the login screen again.

In the same statement in which you execute finish(), execute your animation there too. Then, in the new activity, run another animation. See this code:

fadein.xml

<set xmlns:android="http://schemas.android.com/apk/res/android" 
     android:fillAfter="true">
     <alpha android:fromAlpha="1.0" 
            android:toAlpha="0.0"
            android:duration="500"/> //Time in milliseconds
</set>

In your finish-class

private void finishTask() {
    if("blabbla".equals("blablabla"){
        finish();
        runFadeInAnimation();
    }
}

private void runFadeInAnimation() {
    Animation a = AnimationUtils.loadAnimation(this, R.anim.fadein);
    a.reset();
    LinearLayout ll = (LinearLayout) findViewById(R.id.yourviewhere);
    ll.clearAnimation();
    ll.startAnimation(a);   
}

fadeout.xml

<set xmlns:android="http://schemas.android.com/apk/res/android"
           android:fillAfter="true">
  <alpha android:fromAlpha="0.0"
         android:toAlpha="1.0"
         android:duration="500"/>
</set>

In your new Activity-class you create a similiar method like the runFadeAnimation I wrote and then you run it in onCreate and don't forget to change the resources id to fadeout.

I was wraped it with <> </> as a parent when I changed it to normal , div , its worked fine

In the CSS, a class selector is a name preceded by a full stop (“.”) and an ID selector is a name preceded by a hash character (“#”). The difference between an ID and a class is that an ID can be used to identify one element, whereas a class can be used to identify more than one.

You have two solutions for your problem. The quick one is to lower targetApi to 22 (build.gradle file). Second is to use new and wonderful ask-for-permission model:

if (checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE)
        != PackageManager.PERMISSION_GRANTED) {

    // Should we show an explanation?
    if (shouldShowRequestPermissionRationale(
            Manifest.permission.READ_EXTERNAL_STORAGE)) {
        // Explain to the user why we need to read the contacts
    }

    requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
            MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE);

    // MY_PERMISSIONS_REQUEST_READ_EXTERNAL_STORAGE is an
    // app-defined int constant that should be quite unique

    return;
}

Sniplet found here: https://developer.android.com/training/permissions/requesting.html

Solutions 2: If it does not work try this:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M
    && ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
        REQUEST_PERMISSION);

return;

}

and then in callback

@Override
public void onRequestPermissionsResult(final int requestCode, @NonNull final String[] permissions, @NonNull final int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == REQUEST_PERMISSION) {
    if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
        // Permission granted.
    } else {
        // User refused to grant permission.
    }
}
}

that is from comments. thanks

The TimeSpan constructor allows you to pass in seconds. Simply declare a variable of type TimeSpan amount of seconds. Ex:

TimeSpan span = new TimeSpan(0, 0, 500);
span.ToString();

%matplotlib inline

For me working with notebook, adding the above line before the plot works.

If you see the man page of logger:

$ man logger

LOGGER(1) BSD General Commands Manual LOGGER(1)

NAME logger — a shell command interface to the syslog(3) system log module

SYNOPSIS logger [-isd] [-f file] [-p pri] [-t tag] [-u socket] [message ...]

DESCRIPTION Logger makes entries in the system log. It provides a shell command interface to the syslog(3) system log module.

It Clearly says that it will log to system log. If you want to log to file, you can use ">>" to redirect to log file.

I checked your code and seems to be no problem at all. please make sure Image commandArgument getting value. check it first binding in label whether you are getting value.

However, here is sample which I'm using in my project

<asp:GridView ID="GridViewUserScraps" ItemStyle-VerticalAlign="Top" AutoGenerateColumns="False" Width="100%" runat="server" OnRowCommand="GridViews_RowCommand" >
        <Columns>
            <asp:TemplateField SortExpression="SendDate">
                <ItemTemplate>
                <asp:Button ID="btnPost" CssClass="submitButton" Text="Comment" runat="server" CommandName="Comment" CommandArgument='<%#Eval("ScrapId")+","+ Eval("UserId")%>' />

                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

first bind the GridView.

public void GetData()
{
   //bind ur GridView
   GridViewUserScraps.DataSource = dt;
   GridViewUserScraps.DataBind();
}

protected void GridViews_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "Comment")
    {
        string[] commandArgs = e.CommandArgument.ToString().Split(new char[] { ',' });
        string scrapid = commandArgs[0];
        string uid = commandArgs[1];
    }
}

If it's reasonable to alter the original Map data structure to be serialized to better represent the actual value wanted to be serialized, that's probably a decent approach, which would possibly reduce the amount of Jackson configuration necessary. For example, just remove the null key entries, if possible, before calling Jackson. That said...

To suppress serializing Map entries with null values:

Before Jackson 2.9

you can still make use of WRITE_NULL_MAP_VALUES, but note that it's moved to SerializationFeature:

mapper.configure(SerializationFeature.WRITE_NULL_MAP_VALUES, false);

Since Jackson 2.9

The WRITE_NULL_MAP_VALUES is deprecated, you can use the below equivalent:

mapper.setDefaultPropertyInclusion(
   JsonInclude.Value.construct(Include.ALWAYS, Include.NON_NULL))

To suppress serializing properties with null values, you can configure the ObjectMapper directly, or make use of the @JsonInclude annotation:

mapper.setSerializationInclusion(Include.NON_NULL);

or:

@JsonInclude(Include.NON_NULL)
class Foo
{
  public String bar;

  Foo(String bar)
  {
    this.bar = bar;
  }
}

To handle null Map keys, some custom serialization is necessary, as best I understand.

A simple approach to serialize null keys as empty strings (including complete examples of the two previously mentioned configurations):

import java.io.IOException;
import java.util.HashMap;
import java.util.Map;

import com.fasterxml.jackson.annotation.JsonInclude.Include;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.databind.SerializerProvider;

public class JacksonFoo
{
  public static void main(String[] args) throws Exception
  {
    Map<String, Foo> foos = new HashMap<String, Foo>();
    foos.put("foo1", new Foo("foo1"));
    foos.put("foo2", new Foo(null));
    foos.put("foo3", null);
    foos.put(null, new Foo("foo4"));

    // System.out.println(new ObjectMapper().writeValueAsString(foos));
    // Exception: Null key for a Map not allowed in JSON (use a converting NullKeySerializer?)

    ObjectMapper mapper = new ObjectMapper();
    mapper.configure(SerializationFeature.WRITE_NULL_MAP_VALUES, false);
    mapper.setSerializationInclusion(Include.NON_NULL);
    mapper.getSerializerProvider().setNullKeySerializer(new MyNullKeySerializer());
    System.out.println(mapper.writeValueAsString(foos));
    // output: 
    // {"":{"bar":"foo4"},"foo2":{},"foo1":{"bar":"foo1"}}
  }
}

class MyNullKeySerializer extends JsonSerializer<Object>
{
  @Override
  public void serialize(Object nullKey, JsonGenerator jsonGenerator, SerializerProvider unused) 
      throws IOException, JsonProcessingException
  {
    jsonGenerator.writeFieldName("");
  }
}

class Foo
{
  public String bar;

  Foo(String bar)
  {
    this.bar = bar;
  }
}

To suppress serializing Map entries with null keys, further custom serialization processing would be necessary.

Just an FYI, you can optionally do it from the XML.

In the AndroidManifest.xml, you can set it with

android:label="My Activity Title"

Or

android:label="@string/my_activity_label"

Example:

    <activity
        android:name=".Splash"
        android:label="@string/splash_activity_title" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

Instead of using the placeholder text, you'll want to set the actual text property of the field to MM/YYYY, set the delegate of the text field and listen for this method:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {     // update the text of the label } 

Inside that method, you can figure out what the user has typed as they type, which will allow you to update the label accordingly.

As already mentioned, spring-boot will fetch all you need (for both web and webflux starter).

But what's even better - you don't need to register any modules yourself. Take a look here. Since @SpringBootApplication uses @EnableAutoConfiguration under the hood, it means JacksonAutoConfiguration will be added to the context automatically. Now, if you look inside JacksonAutoConfiguration, you will see:

    private void configureModules(Jackson2ObjectMapperBuilder builder) {
        Collection<Module> moduleBeans = getBeans(this.applicationContext,
                Module.class);
        builder.modulesToInstall(moduleBeans.toArray(new Module[0]));
    }

This fella will be called in the process of initialization and will fetch all the modules it can find in the classpath. (I use Spring Boot 2.1)

just use os.chdir
Example:

>>> import os
>>> import subprocess
>>> # Lets Just Say WE want To List The User Folders
>>> os.chdir("/home/")
>>> subprocess.run("ls")
user1 user2 user3 user4

A more general method to create an arbitrary size data frame is to create a n-by-1 data-frame from a matrix of the same dimension. Then, you can immediately drop the first row:

> v <- data.frame(matrix(NA, nrow=1, ncol=10))
> v <- v[-1, , drop=FALSE]
> v
 [1] X1  X2  X3  X4  X5  X6  X7  X8  X9  X10
<0 rows> (or 0-length row.names)

I had this same problem when trying to upgrade pm2 to the latest version.

Thanks to sdm's answer I did npm update npm -g and it did the trick for me.

ArrayAdapter<String> should work.

i.e.:

Spinner spinner = new Spinner(this);
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>
            (this, android.R.layout.simple_spinner_item,
           spinnerArray); //selected item will look like a spinner set from XML
spinnerArrayAdapter.setDropDownViewResource(android.R.layout
                                                     .simple_spinner_dropdown_item);
spinner.setAdapter(spinnerArrayAdapter); 

If you use jdk8 see @Nathaniel Johnson's answer as that is better.

I think that many of the answer here are complex or not easily read. With branch prediction so efficient why you simply not use a if statement?

public static String join(List<String> fooList){

    if (fooList.isEmpty()) return "";

    StringBuilder sb = null;

    for (String element : fooList) {

        if (sb == null) {
            sb = new StringBuilder();
        } else {
            sb.append(", ");
        }

        sb.append(element);
    }
    return sb.toString();
}

Something that should be mentioned is that Apache uses a simple for loop with an if statement inside it like this (it uses an array as its index to know the first element), and openjdk 8 does the same but in separated methods calls instead of a simple loop.

I ran into a problem where the browser refused to serve up content that it had retrieved when the request passed in cookies (e.g., the xhr had its withCredentials=true), and the site had Access-Control-Allow-Origin set to *. (The error in Chrome was, "Cannot use wildcard in Access-Control-Allow-Origin when credentials flag is true.")

Building on the answer from @jgauffin, I created this, which is basically a way of working around that particular browser security check, so caveat emptor.

public class AllowCrossSiteJsonAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        // We'd normally just use "*" for the allow-origin header, 
        // but Chrome (and perhaps others) won't allow you to use authentication if
        // the header is set to "*".
        // TODO: Check elsewhere to see if the origin is actually on the list of trusted domains.
        var ctx = filterContext.RequestContext.HttpContext;
        var origin = ctx.Request.Headers["Origin"];
        var allowOrigin = !string.IsNullOrWhiteSpace(origin) ? origin : "*";
        ctx.Response.AddHeader("Access-Control-Allow-Origin", allowOrigin);
        ctx.Response.AddHeader("Access-Control-Allow-Headers", "*");
        ctx.Response.AddHeader("Access-Control-Allow-Credentials", "true");
        base.OnActionExecuting(filterContext);
    }
}

I was receiving the error (I'm using Vue) and I switched my onclick="someFunction()" to @click="someFunction" and now they are working.

if rm /bubu 2>/dev/null; then
    echo "Bubu is gone."
else
    echo "Has anyone seen Bubu?" | STDERR
fi


# run the bubu.sh and redirect you output
tux@earth:~$ ./bubu.sh >/tmp/bubu.log 2>/tmp/bubu.err

Usually you don't want just an if but an else clause as well.

if(!(str instanceof String)) { /* do Something */ } 
else { /* do something else */ }

can be written as

if(str instanceof String) { /* do Something else */ } 
else { /* do something */ }

Or you can write the code so you don't need to know if its a String or not. e.g.

if(!(str instanceof String)) { str = str.toString(); } 

can be written as

str = str.toString();

Even this will work nicely

REPT(0,2-LEN(F2)&F2

where 2 is total number of digits, for 0 ~ 9 -> it will display 00 to 09 rest nothing will be added.

You can use jsonpipe if you just need the output (and more comfortable with command line):

cat bookmarks.json | jsonpipe |grep uri

As Davide Gualano has been told. This one

$("#myDiv").load("myScript.php?var=x&var2=y&var3=z")

use GET method for sending the request, and this one

$("#myDiv").load("myScript.php", {var:x, var2:y, var3:z})

use POST method for sending the request. But any limitation that is applied to each method (post/get) is applied to the alternative usages that has been mentioned in the question.

For example: url length limits the amount of sending data in GET method.

I have created an Asset helper of my own.

First I defined the asset types and path in app/config/assets.php:

return array(

    /*
    |--------------------------------------------------------------------------
    | Assets paths
    |--------------------------------------------------------------------------
    |
    | Location of all application assets, relative to the public folder,
    | may be used together with absolute paths or with URLs.
    |
    */

    'images' => '/storage/images',
    'css' => '/assets/css',
    'img' => '/assets/img',
    'js' => '/assets/js'
);

Then the actual Asset class:

class Asset
{
    private static function getUrl($type, $file)
    {
        return URL::to(Config::get('assets.' . $type) . '/' . $file);
    }

    public static function css($file)
    {
        return self::getUrl('css', $file);
    }

    public static function img($file)
    {
        return self::getUrl('img', $file);
    }

    public static function js($file)
    {
        return self::getUrl('js', $file);
    }

}

So in my view I can do this to show an image:

{{ HTML::image(Asset::img('logo.png'), "My logo")) }}

Or like this to implement a Java script:

{{ HTML::script(Asset::js('my_script.js')) }}

When a new view is loaded in AngularJS, Google Analytics does not count it as a new page load. Fortunately there is a way to manually tell GA to log a url as a new pageview.

_gaq.push(['_trackPageview', '<url>']); would do the job, but how to bind that with AngularJS?

Here is a service which you could use:

(function(angular) { 

  angular.module('analytics', ['ng']).service('analytics', [
    '$rootScope', '$window', '$location', function($rootScope, $window, $location) {
      var track = function() {
        $window._gaq.push(['_trackPageview', $location.path()]);
      };
      $rootScope.$on('$viewContentLoaded', track);
    }
  ]);

}(window.angular));

When you define your angular module, include the analytics module like so:

angular.module('myappname', ['analytics']);

UPDATE:

You should use the new Universal Google Analytics tracking code with:

$window.ga('send', 'pageview', {page: $location.url()});

One thing I've not found through the answers is that there are two possible landscape orientations, and I wanted to let both be available! So android:screenOrientation="landscape" will lock your app only to one of the 2 possibilities, but if you want your app to be limited to both landscape orientations (for them whom is not clear, having device on portrait, one is rotating left and the other one rotating right) this is what is needed:

android:screenOrientation="sensorLandscape"

Use method invocation from reflection:

Class<?> c = Class.forName("class name");
Method method = c.getDeclaredMethod("method name", parameterTypes);
method.invoke(objectToInvokeOn, params);

Where:

• "class name" is the name of the class
• objectToInvokeOn is of type Object and is the object you want to invoke the method on
• "method name" is the name of the method you want to call
• parameterTypes is of type Class[] and declares the parameters the method takes
• params is of type Object[] and declares the parameters to be passed to the method

While I agree with Jörn's answer if your class conforms to the JavaBeabs spec, here is a good alternative if it doesn't and you use Spring.

Spring has a class named ReflectionUtils that offers some very powerful functionality, including doWithFields(class, callback), a visitor-style method that lets you iterate over a classes fields using a callback object like this:

public void analyze(Object obj){
    ReflectionUtils.doWithFields(obj.getClass(), field -> {

        System.out.println("Field name: " + field.getName());
        field.setAccessible(true);
        System.out.println("Field value: "+ field.get(obj));

    });
}

But here's a warning: the class is labeled as "for internal use only", which is a pity if you ask me

Open Notepad and write this

@echo off
:A
Cls
echo MESSENGER
set /p n=User:
set /p m=Message:
net send %n% %m%
Pause
Goto A

and then save as "Messenger.bat" and close the Notepad
Step 1:

when you open that saved notepad file it will open as a file Messenger command prompt with this details.

Messenger
User:

after "User" write the ip of the computer you want to contact and then press enter.

Depends what you want to do.

If what you want is to retrieve the bytes that are remaining (between position and limit), then what you have will work. You could also just do:

ByteBuffer bb =..

byte[] b = new byte[bb.remaining()];
bb.get(b);

which is equivalent as per the ByteBuffer javadocs.

json.dumps() converts a dictionary to str object, not a json(dict) object! So you have to load your str into a dict to use it by using json.loads() method

See json.dumps() as a save method and json.loads() as a retrieve method.

This is the code sample which might help you understand it more:

import json

r = {'is_claimed': 'True', 'rating': 3.5}
r = json.dumps(r)
loaded_r = json.loads(r)
loaded_r['rating'] #Output 3.5
type(r) #Output str
type(loaded_r) #Output dict

In VS - project properties - in the Build tab - platform target =X86

SOLUTION

The following code worked for me with jQuery. It works in every browser and allows to preserve events and custom properties.

var $el = $('#uploadCaptureInputFile');
$el.wrap('<form>').closest('form').get(0).reset();
$el.unwrap();

DEMO

See this jsFiddle for code and demonstration.

 var fs = require('fs');
 fs.writeFile(path + "\\message.txt", "Hello", function(err){
 if (err) throw err;
  console.log("success");
}); 

For example : read file and write to another file :

  var fs = require('fs');
    var path = process.cwd();
    fs.readFile(path+"\\from.txt",function(err,data)
                {
                    if(err)

NO,but there are some other options to implement default value. There are some good blog posts on the subject, but here are some specific examples.

// Both parameters are optional, use empty string for default value
func Concat1(a string, b int) string {
  if a == "" {
    a = "default-a"
  }
  if b == 0 {
    b = 5
  }

  return fmt.Sprintf("%s%d", a, b)
}

// a is required, b is optional.
// Only the first value in b_optional will be used.
func Concat2(a string, b_optional ...int) string {
  b := 5
  if len(b_optional) > 0 {
    b = b_optional[0]
  }

  return fmt.Sprintf("%s%d", a, b)
}

// A declarative default value syntax
// Empty values will be replaced with defaults
type Parameters struct {
  A string `default:"default-a"` // this only works with strings
  B string // default is 5
}

func Concat3(prm Parameters) string {
  typ := reflect.TypeOf(prm)

  if prm.A == "" {
    f, _ := typ.FieldByName("A")
    prm.A = f.Tag.Get("default")
  }

  if prm.B == 0 {
    prm.B = 5
  }

  return fmt.Sprintf("%s%d", prm.A, prm.B)
}

func Concat4(args ...interface{}) string {
  a := "default-a"
  b := 5

  for _, arg := range args {
    switch t := arg.(type) {
      case string:
        a = t
      case int:
        b = t
      default:
        panic("Unknown argument")
    }
  }

  return fmt.Sprintf("%s%d", a, b)
}

When you use a function ...

<p onclick="update_url('/en/step2');">Link</p>

<script>
function update_url(url) {
    history.pushState(null, null, url);
}
</script>

An std::vector can be copied around, while unique_ptr<int[]> allows expressing unique ownership of the array. std::array, on the other hand, requires the size to be determined at compile-time, which may be impossible in some situations.

Parent-Child communication in VueJS

Given a root Vue instance is accessible by all descendants via this.$root, a parent component can access child components via the this.$children array, and a child component can access it's parent via this.$parent, your first instinct might be to access these components directly.

The VueJS documentation warns against this specifically for two very good reasons:

• It tightly couples the parent to the child (and vice versa)
• You can't rely on the parent's state, given that it can be modified by a child component.

The solution is to use Vue's custom event interface

The event interface implemented by Vue allows you to communicate up and down the component tree. Leveraging the custom event interface gives you access to four methods:

1. $on() - allows you to declare a listener on your Vue instance with which to listen to events
2. $emit() - allows you to trigger events on the same instance (self)

Example using $on() and $emit():

const events = new Vue({}),_x000D_
    parentComponent = new Vue({_x000D_
      el: '#parent',_x000D_
      ready() {_x000D_
        events.$on('eventGreet', () => {_x000D_
          this.parentMsg = `I heard the greeting event from Child component ${++this.counter} times..`;_x000D_
        });_x000D_
      },_x000D_
      data: {_x000D_
        parentMsg: 'I am listening for an event..',_x000D_
        counter: 0_x000D_
      }_x000D_
    }),_x000D_
    childComponent = new Vue({_x000D_
      el: '#child',_x000D_
      methods: {_x000D_
      greet: function () {_x000D_
        events.$emit('eventGreet');_x000D_
        this.childMsg = `I am firing greeting event ${++this.counter} times..`;_x000D_
      }_x000D_
    },_x000D_
    data: {_x000D_
      childMsg: 'I am getting ready to fire an event.',_x000D_
      counter: 0_x000D_
    }_x000D_
  });

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/1.0.28/vue.min.js"></script>_x000D_
_x000D_
<div id="parent">_x000D_
  <h2>Parent Component</h2>_x000D_
  <p>{{parentMsg}}</p>_x000D_
</div>_x000D_
_x000D_
<div id="child">_x000D_
  <h2>Child Component</h2>_x000D_
  <p>{{childMsg}}</p>_x000D_
  <button v-on:click="greet">Greet</button>_x000D_
</div>

Answer taken from the original post: Communicating between components in VueJS

The best way is to specify the format.

format(a, 'b')

returns the binary value of a in string format.

To convert a binary string back to integer, use int() function.

int('110', 2)

returns integer value of binary string.

Suppose you have this script

<div>
  <p id="response"><p>
  <script>
    var query = document.location.href.substring(document.location.href.indexOf("?") + 1);
    var text_input = query.split("&")[0].split("=")[1];
    document.getElementById('response').innerHTML=text_input;
  </script> </div>

And the url form is www.localhost.com/web_form_response.html?text_input=stack&over=flow

The text written to <p id="response"> will be stack

The reason why most use HashSet is that the operations are (on average) O(1) instead of O(log n). If the set contains standard items you will not be "messing around with hash functions" as that has been done for you. If the set contains custom classes, you have to implement hashCode to use HashSet (although Effective Java shows how), but if you use a TreeSet you have to make it Comparable or supply a Comparator. This can be a problem if the class does not have a particular order.

I have sometimes used TreeSet (or actually TreeMap) for very small sets/maps (< 10 items) although I have not checked to see if there is any real gain in doing so. For large sets the difference can be considerable.

Now if you need the sorted, then TreeSet is appropriate, although even then if updates are frequent and the need for a sorted result is infrequent, sometimes copying the contents to a list or an array and sorting them can be faster.

Check the Initial Catalog parameter in your connection string. It may be that your code is looking in the wrong database for the Projects object.

For example, if you have database syncing setup in such a way that only a subset of the master-database's tables are transferred, you can encounter this error if Linq to SQL is expecting all tables to be in the database pointed to by the connection string.

I had similar problem. I solved it by unchecking "Process explicitly annotated beans" option (see screenshot below). This option is enabled by default on linux. Now @Service and @Configurations annotations are visible. screenshot

You need to declare the type of the protocol as AnyObject.

protocol ProtocolNameDelegate: AnyObject {
    // Protocol stuff goes here
}

class SomeClass {
    weak var delegate: ProtocolNameDelegate?
}

Using AnyObject you say that only classes can conform to this protocol, whereas structs or enums can't.

Try the following (note that there should not be a space between the VAR, =, and GREG).

SET VAR=GREG
ECHO %VAR%

A solution where the logo is truly centered and the links are justified.

The max recommended number of links for the nav is 6, depending on the length of the words in eache link.

If you have 5 links, insert an empty link and style it with:

in this way the number of links is always even.

Running the app on a virtual device with system image, 'Google Play API' instead of 'Google API' will solve your issue smoothly..

• Virtual devices Nexus 5x and Nexus 5 supports 'Google Play API' image.

• Google Play API comes with Nougat 7.1.1 and O 8.0.

Just follow the below simple steps and make sure your pc is connected to internet.

1. Create a new virtual device by selecting Create Virtual Device(left-bottom corner) from Android Virtual Devices Manager.

2. Select the Hardware 'Nexus 5x' or 'Nexus 5'.

3. Download the system image 'Nougat' with Google Play or 'O' with Google Play. 'O' is the latest Android 8.0 version.

4. Click on Next and Finish.

5. Run your app again on the new virtual device and click on the 'Upgrade now ' option that shows along with the warning message.

6. You will be directed to the Play Store and you can update your Google Play services easily.

See your app runs smoothly!

• Note: If you plan to use APIs from Google Play services, you must use the Google APIs System Image.

I had the same problem and the only solution that worked was:

Response.Clear();
Response.ContentType = "Application/msword";
Response.AddHeader("Content-Disposition", "attachment; filename=myfile.docx");
Response.BinaryWrite(myMemoryStream.ToArray());
// myMemoryStream.WriteTo(Response.OutputStream); //works too
Response.Flush();
Response.Close();
Response.End();

Why not just fix the condition in your while loop, causing the problem to disappear?

while(msg->state != DONE)
{
    switch(msg->state) {
    case MSGTYPE: // ... 
        break;
    // ... more stuff ...
    case DONE:
        // We can't get here, but for completeness we list it.
        break; // **HERE, I want to break out of the loop itself**
    }
}

Just to update this question for mod_security 2.7.0+ - they turned off the ability to mitigate modsec via htaccess unless you compile it with the --enable-htaccess-config flag. Most hosts do not use this compiler option since it allows too lax security. Instead, vhosts in httpd.conf are your go-to option for controlling modsec.

Even if you do compile modsec with htaccess mitigation, there are less directives available. SecRuleEngine can no longer be used there for example. Here is a list that is available to use by default in htaccess if allowed (keep in mind a host may further limit this list with AllowOverride):

    - SecAction
    - SecRule

    - SecRuleRemoveByMsg
    - SecRuleRemoveByTag
    - SecRuleRemoveById

    - SecRuleUpdateActionById
    - SecRuleUpdateTargetById
    - SecRuleUpdateTargetByTag
    - SecRuleUpdateTargetByMsg

More info on the official modsec wiki

As an additional note for 2.x users: the IfModule should now look for mod_security2.c instead of the older mod_security.c

A simple solution is encapsulate code of button event in a function, and call it when you add TRs too:

 var i = 1;
$("#addbutton").click(function() {
  $("table tr:first").clone().find("input").each(function() {
    $(this).val('').attr({
      'id': function(_, id) {return id + i },
      'name': function(_, name) { return name + i },
      'value': ''               
    });
  }).end().appendTo("table");
  i++;

  applyRemoveEvent();  
});


function applyRemoveEvent(){
    $('button.removebutton').on('click',function() {
        alert("aa");
      $(this).closest( 'tr').remove();
      return false;
    });
};

applyRemoveEvent();

I implemented many automation cases based on REST Assured , a jave DSL for testing restful service. https://code.google.com/p/rest-assured/

The syntax is easy, it supports json and xml. https://code.google.com/p/rest-assured/wiki/Usage

Before that, I tried SOAPUI and had some issues with the free version. Plus the cases are in xml files which hard to extend and reuse, simply I don't like

These do the same thing:

window.location.assign(url);
window.location = url;
window.location.href = url;

They simply navigate to the new URL. The replace method on the other hand navigates to the URL without adding a new record to the history.

So, what you have read in those many forums is not correct. The assign method does add a new record to the history.
