In addition to Mark's answer, you also need to be aware of scope, which (as in C/C++) is specified using braces. So:

if (textBox1.Text == "" || textBox1.Text == String.Empty || textBox1.TextLength == 0)
    textBox3.Text += "[-] Listbox is Empty!!!!\r\n";
return;

will always return at that point. However:

if (textBox1.Text == "" || textBox1.Text == String.Empty || textBox1.TextLength == 0)
{
    textBox3.Text += "[-] Listbox is Empty!!!!\r\n";
    return;
}

will only return if it goes into that if statement.

If I use exit() in a code and run it in the shell, it shows a message asking whether I want to kill the program or not. It's really disturbing. See here

But sys.exit() is better in this case. It closes the program and doesn't create any dialogue box.

In main(), there is also:

return 0;

If you're looking for a way to forcibly terminate execution of all Javascript on a page, I'm not sure there is an officially sanctioned way to do that - it seems like the kind of thing that might be a security risk (although to be honest, I can't think of how it would be off the top of my head). Normally in Javascript when you want your code to stop running, you just return from whatever function is executing. (The return statement is optional if it's the last thing in the function and the function shouldn't return a value) If there's some reason returning isn't good enough for you, you should probably edit more detail into the question as to why you think you need it and perhaps someone can offer an alternate solution.

Note that in practice, most browsers' Javascript interpreters will simply stop running the current script if they encounter an error. So you can do something like accessing an attribute of an unset variable:

function exit() {
    p.blah();
}

and it will probably abort the script. But you shouldn't count on that because it's not at all standard, and it really seems like a terrible practice.

EDIT: OK, maybe this wasn't such a good answer in light of Ólafur's. Although the die() function he linked to basically implements my second paragraph, i.e. it just throws an error.

I have a set of scripting functions that I use extensively on my Red Hat system. They use the system functions from /etc/init.d/functions to print green [ OK ] and red [FAILED] status indicators.

You can optionally set the $LOG_STEPS variable to a log file name if you want to log which commands fail.

Usage

step "Installing XFS filesystem tools:"
try rpm -i xfsprogs-*.rpm
next

step "Configuring udev:"
try cp *.rules /etc/udev/rules.d
try udevtrigger
next

step "Adding rc.postsysinit hook:"
try cp rc.postsysinit /etc/rc.d/
try ln -s rc.d/rc.postsysinit /etc/rc.postsysinit
try echo $'\nexec /etc/rc.postsysinit' >> /etc/rc.sysinit
next

Output

Installing XFS filesystem tools:        [  OK  ]
Configuring udev:                       [FAILED]
Adding rc.postsysinit hook:             [  OK  ]

Code

# Use step(), try(), and next() to perform a series of commands and print
# [  OK  ] or [FAILED] at the end. The step as a whole fails if any individual

Use it in conjunction with pipefail.

set -e
set -o pipefail

-e (errexit): Abort the script at the first error, when a command exits with non-zero status (except in until or while loops, if-tests, and list constructs)

-o pipefail: Causes a pipeline to return the exit status of the last command in the pipe that returned a non-zero return value.

Chapter 33. Options

Provided my_command is canonically designed, ie returns 0 when succeeds, then && is exactly the opposite of what you want. You want ||.

Also note that ( does not seem right to me in bash, but I cannot try from where I am. Tell me.

my_command || {
    echo 'my_command failed' ;
    exit 1; 
}

A better user experience:

/**
 * Back button listener.
 * Will close the application if the back button pressed twice.
 */
@Override
public void onBackPressed()
{
    if(backButtonCount >= 1)
    {
        Intent intent = new Intent(Intent.ACTION_MAIN);
        intent.addCategory(Intent.CATEGORY_HOME);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);
    }
    else
    {
        Toast.makeText(this, "Press the back button once again to close the application.", Toast.LENGTH_SHORT).show();
        backButtonCount++;
    }
}

In both Visual Basic 6.0 and VB.NET you would use:

• Exit For to break from For loop
• Wend to break from While loop
• Exit Do to break from Do loop

depending on the loop type. See Exit Statements for more details.

Similar idea to yeh answer, just minimalist alternative.

Create a batch file with the following content:

helloworld.exe
pause

Then use the batch file.

Below used main.xml file

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:layout_width="fill_parent"
    android:layout_height="wrap_content" android:id="@+id/txt1" android:text="txt1" />
<TextView android:layout_width="fill_parent"
    android:layout_height="wrap_content" android:id="@+id/txt2"   android:text="txt2"/>
<Button android:layout_width="fill_parent"
    android:layout_height="wrap_content" android:id="@+id/btn1"
    android:text="Close App" />
  </LinearLayout>

and text.java file is below

import android.app.Activity;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

public class testprj extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Button btn1 = (Button) findViewById(R.id.btn1);
    btn1.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            finish();
            System.exit(0);
        }
    });
    }
 }

You can use Environment.Exit(0); and Application.Exit

Environment.Exit(0) is cleaner.

Below is the fixed code:

#!/bin/ksh
safeRunCommand() {
  typeset cmnd="$*"
  typeset ret_code

  echo cmnd=$cmnd
  eval $cmnd
  ret_code=$?
  if [ $ret_code != 0 ]; then
    printf "Error : [%d] when executing command: '$cmnd'" $ret_code
    exit $ret_code
  fi
}

command="ls -l | grep p"
safeRunCommand "$command"

Now if you look into this code few things that I changed are:

• use of typeset is not necessary but a good practice. It make cmnd and ret_code local to safeRunCommand
• use of ret_code is not necessary but a good practice to store return code in some variable (and store it ASAP) so that you can use it later like I did in printf "Error : [%d] when executing command: '$command'" $ret_code
• pass the command with quotes surrounding the command like safeRunCommand "$command". If you dont then cmnd will get only the value ls and not ls -l. And it is even more important if your command contains pipes.
• you can use typeset cmnd="$*" instead of typeset cmnd="$1" if you want to keep the spaces. You can try with both depending upon how complex is your command argument.
• eval is used to evaluate so that command containing pipes can work fine

NOTE: Do remember some commands give 1 as return code even though there is no error like grep. If grep found something it will return 0 else 1.

I had tested with KSH/BASH. And it worked fine. Let me know if u face issues running this.

As stated before, these two commands produce the same parser token.

BUT

There is a small difference, and that is how long it takes the parser to return the token.

I haven't studied the PHP parser, but if it's a long list of functions starting with "d", and a shorter list starting with "e", then there must be a time penalty looking up the function name for functions starting with "e". And there may be other differences due to how the whole function name is checked.

I doubt it will be measurable unless you have a "perfect" environment dedicated to parsing PHP, and a lot of requests with different parameters. But there must be a difference, after all, PHP is an interpreted language.

Are you looking for exit?

This is the best bash guide around. http://tldp.org/LDP/abs/html/

In context:

if jarsigner -verbose -keystore $keyst -keystore $pass $jar_file $kalias
then
    echo $jar_file signed sucessfully
else
    echo ERROR: Failed to sign $jar_file. Please recheck the variables 1>&2
    exit 1 # terminate and indicate error
fi

...

return in function return execution back to caller and exit from function terminates the program.

in main function return 0 or exit(0) are same but if you write exit(0) in different function then you program will exit from that position.

returning different values like return 1 or return -1 means that program is returning error .

When exit(0) is used to exit from program, destructors for locally scoped non-static objects are not called. But destructors are called if return 0 is used.

exit(X), where X is a number (according to the doc) should work. But it is not recommended by Apple and won't be accepted by the AppStore. Why? Because of these guidelines (one of my app got rejected):

We found that your app includes a UI control for quitting the app. This is not in compliance with the iOS Human Interface Guidelines, as required by the App Store Review Guidelines.

Please refer to the attached screenshot/s for reference.

The iOS Human Interface Guidelines specify,

"Always Be Prepared to Stop iOS applications stop when people press the Home button to open a different application or use a device feature, such as the phone. In particular, people don’t tap an application close button or select Quit from a menu. To provide a good stopping experience, an iOS application should:

Save user data as soon as possible and as often as reasonable because an exit or terminate notification can arrive at any time.

Save the current state when stopping, at the finest level of detail possible so that people don’t lose their context when they start the application again. For example, if your app displays scrolling data, save the current scroll position."

> It would be appropriate to remove any mechanisms for quitting your app.

Plus, if you try to hide that function, it would be understood by the user as a crash.

you didn't import sys in your code, nor did you close the () when calling the function... try:

import sys
sys.exit()

I had the Same problem, I have one LoginActivity and one MainActivity. If I click back button in MainActivity, Application has to close. SO I did with OnBackPressed method. this moveTaskToBack() work as same as Home Button. It leaves the Back stack as it is.

public void onBackPressed() {
  //  super.onBackPressed();
    moveTaskToBack(true);

}

if you write while(true). its means that loop will not stop in any situation for stop this loop you have to use break statement between while block.

package com.java.demo;

/**
 * @author Ankit Sood Apr 20, 2017
 */
public class Demo {

    /**
     * The main method.
     *
     * @param args
     *            the arguments
     */
    public static void main(String[] args) {
        /* Initialize while loop */
        while (true) {
            /*
            * You have to declare some condition to stop while loop 

            * In which situation or condition you want to terminate while loop.
            * conditions like: if(condition){break}, if(var==10){break} etc... 
            */

            /* break keyword is for stop while loop */

            break;
        }
    }
}

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

git update-ref refs/heads/master b918ac16a33881ce00799bea63d9c23bf7022d67

Then, abort the rebase again.

There is another option, to use the FinishAffinity method to close all the tasks in the stack related to the app.

See: https://stackoverflow.com/a/27765687/1984636

exit() should do it.

Use a try...catch statement in your main function and whenever you want to stop the function just use:

throw new Error("Stopping the function!");

Use:

return [n]

From help return

return: return [n]

Return from a shell function.

Causes a function or sourced script to exit with the return value
specified by N.  If N is omitted, the return status is that of the
last command executed within the function or script.

Exit Status:
Returns N, or failure if the shell is not executing a function or script.

if you need to close your application from main() you can use this code

int main(int argc, char *argv[]){
QApplication app(argc, argv);
...
if(!QSslSocket::supportsSsl()) return app.exit(0);
...
return app.exec();
}

The program will terminated if OpenSSL is not installed

Edit: Seems the OP is running a long script, in that case one only needs to wrap the part of the script after the quality control with

if (n >= 500) {

.... long running code here

}

If breaking out of a function, you'll probably just want return(), either explicitly or implicitly.

For example, an explicit double return

foo <- function(x) {
  if(x < 10) {
    return(NA)
  } else {
    xx <- seq_len(x)
    xx <- cumsum(xx)
  }
  xx ## return(xx) is implied here
}

> foo(5)
[1] 0
> foo(10)
 [1]  1  3  6 10 15 21 28 36 45 55

By return() being implied, I mean that the last line is as if you'd done return(xx), but it is slightly more efficient to leave off the call to return().

Some consider using multiple returns bad style; in long functions, keeping track of where the function exits can become difficult or error prone. Hence an alternative is to have a single return point, but change the return object using the if () else () clause. Such a modification to foo() would be

foo <- function(x) {
  ## out is NA or cumsum(xx) depending on x
  out <- if(x < 10) {
    NA
  } else {
    xx <- seq_len(x)
    cumsum(xx)
  }
  out ## return(out) is implied here
}

> foo(5)
[1] NA
> foo(10)
 [1]  1  3  6 10 15 21 28 36 45 55

The following code will not raise an exception and will exit without a traceback:

import os
os._exit(1)

See this question and related answers for more details. Surprised why all other answers are so overcomplicated.

loop {   begin     Bar.new   rescue SystemExit     p $!  #: #<SystemExit: exit>   end } 

This will print #<SystemExit: exit> in an infinite loop, without ever exiting.

• return returns from the current function; it's a language keyword like for or break.
• exit() terminates the whole program, wherever you call it from. (After flushing stdio buffers and so on).

The only case when both do (nearly) the same thing is in the main() function, as a return from main performs an exit().

In most C implementations, main is a real function called by some startup code that does something like int ret = main(argc, argv); exit(ret);. The C standard guarantees that something equivalent to this happens if main returns, however the implementation handles it.

Example with return:

#include <stdio.h>

void f(){
    printf("Executing f\n");
    return;
}

int main(){
    f();
    printf("Back from f\n");
}

If you execute this program it prints:

Executing f
Back from f

Another example for exit():

#include <stdio.h>
#include <stdlib.h>

void f(){
    printf("Executing f\n");
    exit(0);
}

int main(){
    f();
    printf("Back from f\n");
}

If you execute this program it prints:

Executing f

You never get "Back from f". Also notice the #include <stdlib.h> necessary to call the library function exit().

Also notice that the parameter of exit() is an integer (it's the return status of the process that the launcher process can get; the conventional usage is 0 for success or any other value for an error).

The parameter of the return statement is whatever the return type of the function is. If the function returns void, you can omit the return at the end of the function.

Last point, exit() come in two flavors _exit() and exit(). The difference between the forms is that exit() (and return from main) calls functions registered using atexit() or on_exit() before really terminating the process while _exit() (from #include <unistd.h>, or its synonymous _Exit from #include <stdlib.h>) terminates the process immediately.

Now there are also issues that are specific to C++.

C++ performs much more work than C when it is exiting from functions (return-ing). Specifically it calls destructors of local objects going out of scope. In most cases programmers won't care much of the state of a program after the processus stopped, hence it wouldn't make much difference: allocated memory will be freed, file ressource closed and so on. But it may matter if your destructor performs IOs. For instance automatic C++ OStream locally created won't be flushed on a call to exit and you may lose some unflushed data (on the other hand static OStream will be flushed).

This won't happen if you are using the good old C FILE* streams. These will be flushed on exit(). Actually, the rule is the same that for registered exit functions, FILE* will be flushed on all normal terminations, which includes exit(), but not calls to _exit() or abort().

You should also keep in mind that C++ provide a third way to get out of a function: throwing an exception. This way of going out of a function will call destructor. If it is not catched anywhere in the chain of callers, the exception can go up to the main() function and terminate the process.

Destructors of static C++ objects (globals) will be called if you call either return from main() or exit() anywhere in your program. They wont be called if the program is terminated using _exit() or abort(). abort() is mostly useful in debug mode with the purpose to immediately stop the program and get a stack trace (for post mortem analysis). It is usually hidden behind the assert() macro only active in debug mode.

When is exit() useful ?

exit() means you want to immediately stops the current process. It can be of some use for error management when we encounter some kind of irrecoverable issue that won't allow for your code to do anything useful anymore. It is often handy when the control flow is complicated and error codes has to be propagated all way up. But be aware that this is bad coding practice. Silently ending the process is in most case the worse behavior and actual error management should be preferred (or in C++ using exceptions).

Direct calls to exit() are especially bad if done in libraries as it will doom the library user and it should be a library user's choice to implement some kind of error recovery or not. If you want an example of why calling exit() from a library is bad, it leads for instance people to ask this question.

There is an undisputed legitimate use of exit() as the way to end a child process started by fork() on Operating Systems supporting it. Going back to the code before fork() is usually a bad idea. This is the rationale explaining why functions of the exec() family will never return to the caller.

The OP's question: What is the difference between the return and exit statement in BASH functions with respect to exit codes?

Firstly, some clarification is required:

• A (return|exit) statement is not required to terminate execution of a (function|shell). A (function|shell) will terminate when it reaches the end of its code list, even with no (return|exit) statement.

• A (return|exit) statement is not required to pass a value back from a terminated (function|shell). Every process has a built-in variable $? which always has a numeric value. It is a special variable that cannot be set like "?=1", but it is set only in special ways (see below *).

  The value of $? after the last command to be executed in the (called function | sub shell) is the value that is passed back to the (function caller | parent shell). That is true whether the last command executed is ("return [n]"| "exit [n]") or plain ("return" or something else which happens to be the last command in the called function's code.

In the above bullet list, choose from "(x|y)" either always the first item or always the second item to get statements about functions and return, or shells and exit, respectively.

What is clear is that they both share common usage of the special variable $? to pass values upwards after they terminate.

* Now for the special ways that $? can be set:

• When a called function terminates and returns to its caller then $? in the caller will be equal to the final value of $? in the terminated function.
• When a parent shell implicitly or explicitly waits on a single sub shell and is released by termination of that sub shell, then $? in the parent shell will be equal to the final value of $? in the terminated sub shell.
• Some built-in functions can modify $? depending upon their result. But some don't.
• Built-in functions "return" and "exit", when followed by a numerical argument both $? with argument, and terminate execution.

It is worth noting that $? can be assigned a value by calling exit in a sub shell, like this:

# (exit 259)
# echo $?
3

In that case, it's not needed. No extra threads will have been started up, you're not changing the exit code (which defaults to 0) - basically it's pointless.

When the docs say the method never returns normally, it means the subsequent line of code is effectively unreachable, even though the compiler doesn't know that:

System.exit(0);
System.out.println("This line will never be reached");

Either an exception will be thrown, or the VM will terminate before returning. It will never "just return".

It's very rare to be worth calling System.exit() IME. It can make sense if you're writing a command line tool, and you want to indicate an error via the exit code rather than just throwing an exception... but I can't remember the last time I used it in normal production code.

You can alter the flow of execution using GOTO statements:

IF @ValidationResult = 0
BEGIN
    PRINT 'Validation fault.'
    GOTO EndScript
END

/* our code */

EndScript:

A SysOps guy once taught me the Three-Fingered Claw technique:

yell() { echo "$0: $*" >&2; }
die() { yell "$*"; exit 111; }
try() { "$@" || die "cannot $*"; }

These functions are *NIX OS and shell flavor-robust. Put them at the beginning of your script (bash or otherwise), try() your statement and code on.

Explanation

(based on flying sheep comment).

• yell: print the script name and all arguments to stderr:
  • $0 is the path to the script ;
  • $* are all arguments.
  • >&2 means > redirect stdout to & pipe 2. pipe 1 would be stdout itself.
• die does the same as yell, but exits with a non-0 exit status, which means “fail”.
• try uses the || (boolean OR), which only evaluates the right side if the left one failed.
  • $@ is all arguments again, but different.

Just put "End" keyword in your code.

Sub Form_Load()
  Dim answer As MsgBoxResult
  answer = MsgBox("Do you want to quit now?", MsgBoxStyle.YesNo)
  If answer = MsgBoxResult.Yes Then
      MsgBox("Terminating program")
      End 
  End If 
End Sub

The actual way to end a program, is to call

raise SystemExit

It's what sys.exit does, anyway.

A plain SystemExit, or with None as a single argument, sets the process' exit code to zero. Any non-integer exception value (raise SystemExit("some message")) prints the exception value to sys.stderr and sets the exit code to 1. An integer value sets the process' exit code to the value:

$ python -c "raise SystemExit(4)"; echo $?
4

I would either one of the following:

Application.Exit();

for a winform or

Environment.Exit(0);

for a console application (works on winforms too).

Thanks!

If you are trying to reference an android style, you need to put "android:" in there

android:theme="@android:style/Theme.Black"

If that doesn't solve it, you may need to edit your question with the full manifest file, so we can see more details

You can use an anonymous function to pass the matches to your function:

$result = preg_replace_callback(
    "/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
    function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
    $result
);

Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e would convert a double quote " into \".

There are two types of contexts we are dealing with:

1: root context (parent context. Typically include all jdbc(ORM, Hibernate) initialisation and other spring security related configuration)

2: individual servlet context (child context.Typically Dispatcher Servlet Context and initialise all beans related to spring-mvc (controllers , URL Mapping etc)).

We don't have this problem if we are testing our client request with localhost destination address (host or hostname on node.js) and our server common name is CN = localhost in the server cert. But even if we change localhost for 127.0.0.1 or any other IP we'll get error Hostname/IP doesn't match certificate's altnames on node.js or SSL handshake failed on QT.

I had the same issue about my server certificate on my client request. To solve it on my client node.js app I needed to put a subjectAltName on my server_extension with the following value:

[ server_extension ]
       .
       .
       .

subjectAltName          = @alt_names_server

[alt_names_server]
IP.1 = x.x.x.x

and then I use -extension when I create and sign the certificate.

example:

In my case, I first export the issuer's config file because this file contents the server_extension:

export OPENSSL_CONF=intermed-ca.cnf

so I create and sign my server cert:

openssl ca \
    -in server.req.pem \
    -out server.cert.pem \
    -extensions server_extension \
    -startdate `date +%y%m%d000000Z -u -d -2day` \
    -enddate `date +%y%m%d000000Z -u -d +2years+1day`   

It works fine on clients based on node.js with https requests but it doesn't work with clients based on QT QSsl when we define sslConfiguration.setPeerVerifyMode(QSslSocket::VerifyPeer), unless we use QSslSocket::VerifyNone it won't work. If we use VerifyNone it will make our app to don't check the peer certificate so it'll accept any cert. So, to solve it I need to change my server common name on its cert and replace its value for the IP Address where my server is running.

for example:

CN = 127.0.0.1

I think you could write it that way too. I am also a student so I understand your struggle. A bit late response but ok .

#include<stdio.h>
#define n 3

struct {
    double p[3];//position
    double v[3];//velocity
    double a[3];//acceleration
    double radius;
    double mass;
}bodies[n];

My Kotlin extension . write once use everywhere

fun EditText.tooglePassWord() {
this.tag = !((this.tag ?: false) as Boolean)
this.inputType = if (this.tag as Boolean)
    InputType.TYPE_TEXT_VARIATION_PASSWORD
else
    (InputType.TYPE_CLASS_TEXT or InputType.TYPE_TEXT_VARIATION_PASSWORD)

this.setSelection(this.length()) }

You can keep this method in any file and use it everywhere use it like this

ivShowPassword.click { etPassword.tooglePassWord() }

where ivShowPassword is clicked imageview (eye) and etPassword is Editext

Try this:

    list.setOnItemSelectedListener(new OnItemSelectedListener() {

    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1,
            int arg2, long arg3)
    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {

    }
});

As others have pointed out this is because MySQL is installed but the service isn't running. There are many ways to start the MySQL service and what worked for me is the below.

To start the service:

1. Go to "System Preference"
2. At the bottom pane there should be MySql icon.
3. Double click that to launch the 'MySQL Server Status' and press the button 'Start MySQL Server'

My env:

Mac Yosemite 10.10.3

Installed Package: /Volumes/mysql-advanced-5.6.24-osx10.8-x86_64

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

table {
  width:200px;
}

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

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

Of course. The whole idea of abstract classes is that they can contain some behaviour or data which you require all sub-classes to contain. Think of the simple example of WheeledVehicle - it should have a numWheels member variable. You want all sub classes to have this variable. Remember that abstract classes are a very useful feature when developing APIs, as they can ensure that people who extend your API won't break it.

You can try Jzy3d. It helps drawing simple 3d charts (surfaces, scatters, bars, etc), and has lot of options for customizing layout of axes, ticks, etc. There are lot of examples and a documentation on the wiki.

It's free and open source.

Whenever I have a NuGet error such as these I usually take these steps:

1. Go to the packages folder in the Windows Explorer and delete it.
2. Open Visual Studio and Go to Tools > Library Package Manager > Package Manager Settings and under the Package Manager item on the left hand side there is a "Clear Package Cache" button. Click this button and make sure that the check box for "Allow NuGet to download missing packages during build" is checked.
3. Clean the solution
4. Then right click the solution in the Solution Explorer and enable NuGet Package Restore
5. Build the solution
6. Restart Visual Studio

Taking all of these steps almost always restores all the packages and dll's I need for my MVC program.

EDIT >>>

For Visual Studio 2013 and above, step 2) should read:

2. Open Visual Studio and go to Tools > Options > NuGet Package Manager and on the right hand side there is a "Clear Package Cache button". Click this button and make sure that the check boxes for "Allow NuGet to download missing packages" and "Automatically check for missing packages during build in Visual Studio" are checked.

Old question, but Elevation, available with Material Design now provides a shadow to any views.

<TextView
android:id="@+id/myview"
...

This guide on atlassian's website is one of the best I have found:

https://www.atlassian.com/git/migration

This tool - https://bitbucket.org/atlassian/svn-migration-scripts - is also really useful for generating your authors.txt among other things.

I've just checked and i have the same code as you and it works perferctly. The only difference is how i fill my List for the params :

I use a : ArrayList<BasicNameValuePair> params

and fill it this way :

 params.add(new BasicNameValuePair("apikey", apikey);

I do not use any JSONObject to send params to the webservices.

Are you obliged to use the JSONObject ?

Javascript inheritance seems to be like an open debate everywhere. It can be called "The curious case of Javascript language".

The idea is that there is a base class and then you extend the base class to get an inheritance-like feature (not completely, but still).

The whole idea is to get what prototype really means. I did not get it until I saw John Resig's code (close to what jQuery.extend does) wrote a code chunk that does it and he claims that base2 and prototype libraries were the source of inspiration.

Here is the code.

    /* Simple JavaScript Inheritance
     * By John Resig http://ejohn.org/
     * MIT Licensed.
     */  
     // Inspired by base2 and Prototype
    (function(){
  var initializing = false, fnTest = /xyz/.test(function(){xyz;}) ? /\b_super\b/ : /.*/;

  // The base Class implementation (does nothing)
  this.Class = function(){};

  // Create a new Class that inherits from this class
  Class.extend = function(prop) {
    var _super = this.prototype;

    // Instantiate a base class (but only create the instance,
    // don't run the init constructor)
    initializing = true;
    var prototype = new this();
    initializing = false;

    // Copy the properties over onto the new prototype
    for (var name in prop) {
      // Check if we're overwriting an existing function
      prototype[name] = typeof prop[name] == "function" &&
        typeof _super[name] == "function" && fnTest.test(prop[name]) ?
        (function(name, fn){
          return function() {
            var tmp = this._super;

            // Add a new ._super() method that is the same method
            // but on the super-class
            this._super = _super[name];

            // The method only need to be bound temporarily, so we
            // remove it when we're done executing
            var ret = fn.apply(this, arguments);        
            this._super = tmp;

            return ret;
          };
        })(name, prop[name]) :
        prop[name];
    }

    // The dummy class constructor
    function Class() {
      // All construction is actually done in the init method
      if ( !initializing && this.init )
        this.init.apply(this, arguments);
    }

    // Populate our constructed prototype object
    Class.prototype = prototype;

    // Enforce the constructor to be what we expect
    Class.prototype.constructor = Class;

    // And make this class extendable
    Class.extend = arguments.callee;

    return Class;
  };
})();

There are three parts which are doing the job. First, you loop through the properties and add them to the instance. After that, you create a constructor for later to be added to the object.Now, the key lines are:

// Populate our constructed prototype object
Class.prototype = prototype;

// Enforce the constructor to be what we expect
Class.prototype.constructor = Class;

You first point the Class.prototype to the desired prototype. Now, the whole object has changed meaning that you need to force the layout back to its own one.

And the usage example:

var Car = Class.Extend({
  setColor: function(clr){
    color = clr;
  }
});

var volvo = Car.Extend({
   getColor: function () {
      return color;
   }
});

if you have installed NDK succesfully then start with it sample application

I also want to know is it possible to push the compiled binary into android device or AVD and run using the terminal of the android device or AVD?

here you can see NestedVM

NestedVM provides binary translation for Java Bytecode. This is done by having GCC compile to a MIPS binary which is then translated to a Java class file. Hence any application written in C, C++, Fortran, or any other language supported by GCC can be run in 100% pure Java with no source changes.

Example: Cross compile Hello world C program and run it on android

If you want to do this for various tables at once, you meed to use the -t switch multiple times (took me a while to figure out why comma separated list wasn't working). Also, can be useful to send results to an outfile or pipe to a postgres server on another machine

pg_dump -t table1 -t table2 database_name --schema-only > dump.sql

pg_dump -t table1 -t table2 database_name --schema-only | psql -h server_name database_name

From MSDN:

Top-level types, which are not nested in other types, can only have internal or public accessibility. The default accessibility for these types is internal.

I also recommend this program: http://www.timesynctool.com/

Place the wkhtmltopdf executable on the server and chmod it +x.

Create an executable shell script wrap.sh containing:

#!/bin/sh
export HOME="$PWD"
export LD_LIBRARY_PATH="$PWD/lib/"
exec $@ 2>/dev/null
#exec $@ 2>&1 # debug mode

Download needed shared objects for that architecture and place them an a folder named "lib":

• lib/libfontconfig.so.1.3.0
• lib/libfreetype.so.6
• lib/libfreetype.so.6.3.18

If you experience font problems like squares for all the characters, define TrueType fonts explicitly:

@font-face {
  font-family:Trebuchet MS;
  font-style:normal;
  font-weight:normal;
  src:url("http://www.yourserver.tld/fonts/Trebuchet_MS.ttf");
  format(TrueType);
}

Just another case. I copied a solution with two projects and renamed them partially in the Windows explorer (folder names, .sln and .csproj file names) and partially with a massive Find & Replace action in Visual Studio (namespaces etc.). Nevertheless the exception stated by the OP still occurred. I found out that the Assembly and Namespace names were still old.

Although the project and everything else was already named OfficeStyle the Assembly name and Default namespace were still named Linckus.

After this correction everything worked fine again, compile and run time :)

v-flex does not have a display flex! Inspect v-flex in your browser and you will find out it is just a simple block div.

So, you should override it with display: flex in your HTML or CSS to make it work with justify-content.

Pure JavaScript:

var button = document.getElementById('button'); // Assumes element with id='button'

button.onclick = function() {
    var div = document.getElementById('newpost');
    if (div.style.display !== 'none') {
        div.style.display = 'none';
    }
    else {
        div.style.display = 'block';
    }
};

SEE DEMO

jQuery:

$("#button").click(function() { 
    // assumes element with id='button'
    $("#newpost").toggle();
});

SEE DEMO

You are getting confused with transclude: true, which would append the inner content.

replace: true means that the content of the directive template will replace the element that the directive is declared on, in this case the <div myd1> tag.

http://plnkr.co/edit/k9qSx15fhSZRMwgAIMP4?p=preview

For example without replace:true

<div myd1><span class="replaced" myd1="">directive template1</span></div>

and with replace:true

<span class="replaced" myd1="">directive template1</span>

As you can see in the latter example, the div tag is indeed replaced.

MySQL casts to Decimal:

Cast bare integer to decimal:

select cast(9 as decimal(4,2));       //prints 9.00

Cast Integers 8/5 to decimal:

select cast(8/5 as decimal(11,4));    //prints 1.6000

Cast string to decimal:

select cast(".885" as decimal(11,3));   //prints 0.885

Cast two int variables into a decimal

mysql> select 5 into @myvar1;
Query OK, 1 row affected (0.00 sec)

mysql> select 8 into @myvar2;
Query OK, 1 row affected (0.00 sec)

mysql> select @myvar1/@myvar2;   //prints 0.6250

Cast decimal back to string:

select cast(1.552 as char(10));   //shows "1.552"

...and the exact same arguments apply to this construct as well:

lock(typeof(SomeObject))

Right so there is a huge debate over detecting touch/non-touch devices. The number of window tablets and the size of tablets is increasing creating another set of headaches for us web developers.

I have used and tested blmstr's answer for a menu. The menu works like this: when the page loads the script detects if this is a touch or non touch device. Based on that the menu would work on hover (non-touch) or on click/tap (touch).

In most of the cases blmstr's scripts seemed to work just fine (specifically the 2018 one). BUT there was still that one device that would be detected as touch when it is not or vice versa.

For this reason I did a bit of digging and thanks to this article I replaced a few lines from blmstr's 4th script into this:

function is_touch_device4() {
    if ("ontouchstart" in window)
        return true;

    if (window.DocumentTouch && document instanceof DocumentTouch)
        return true;


    return window.matchMedia( "(pointer: coarse)" ).matches;
}

alert('Is touch device: '+is_touch_device4());
console.log('Is touch device: '+is_touch_device4());

Because of the lockdown have a limited supply of touch devices to test this one but so far the above works great.

I would appreceate if anyone with a desktop touch device (ex. surface tablet) can confirm if script works all right.

Now in terms of support the pointer: coarse media query seems to be supported. I kept the lines above since I had (for some reason) issues on mobile firefox but the lines above the media query do the trick.

Thanks

This link provides a lot of resources for VB6 Decompiling, but it seems like it will depend greatly on what you DO have (do you still have the pre-link Object code [EDIT: er... p-code I mean], or just the EXE?) Either way, it looks like there's something, take a look in there.

Simply pass the sorted items from the dictionary to the plot() function. concentration.items() returns a list of tuples where each tuple contains a key from the dictionary and its corresponding value.

You can take advantage of list unpacking (with *) to pass the sorted data directly to zip, and then again to pass it into plot():

import matplotlib.pyplot as plt

concentration = {
    0: 0.19849878712984576,
    5000: 0.093917341754771386,
    10000: 0.075060643507712022,
    20000: 0.06673074282575861,
    30000: 0.057119318961966224,
    50000: 0.046134834546203485,
    100000: 0.032495766396631424,
    200000: 0.018536317451599615,
    500000: 0.0059499290585381479}

plt.plot(*zip(*sorted(concentration.items())))
plt.show()

sorted() sorts tuples in the order of the tuple's items so you don't need to specify a key function because the tuples returned by dict.item() already begin with the key value.

I had a similar related question: What if you wanted the original object format back (with key names, e.g. FOO, BAR)?

Jq provides to_entries and from_entries to convert between objects and key-value pair arrays. That along with map around the select

These functions convert between an object and an array of key-value pairs. If to_entries is passed an object, then for each k: v entry in the input, the output array includes {"key": k, "value": v}.

from_entries does the opposite conversion, and with_entries(foo) is a shorthand for to_entries | map(foo) | from_entries, useful for doing some operation to all keys and values of an object. from_entries accepts key, Key, name, Name, value and Value as keys.

jq15 < json 'to_entries | map(select(.value.location=="Stockholm")) | from_entries'

{
  "FOO": {
    "name": "Donald",
    "location": "Stockholm"
  },
  "BAR": {
    "name": "Walt",
    "location": "Stockholm"
  }
}

Using the with_entries shorthand, this becomes:

jq15 < json 'with_entries(select(.value.location=="Stockholm"))'
{
  "FOO": {
    "name": "Donald",
    "location": "Stockholm"
  },
  "BAR": {
    "name": "Walt",
    "location": "Stockholm"
  }
}

extend class to AppCompatActivity instead of Activity

Two things you can do:

1. Change #childdivimage to a span element, and change #parentdivimage to an anchor tag. This may require you to add some more styling to get things looking perfect. This is preffered, since it uses semantic markup, and does not rely on javascript.

2. Use Javascript to bind a click event to #parentdivimage. You must redirect the browser window by modifying window.location inside this event. This is TheEasyWay^TM, but will not degrade gracefully.

It is possible to disable ARC (Automatic Reference Counting) for particular file in Xcode.

Select Target -> Build Phases -> Compile Sources -> Select File (double click) -> Add "-fno-objc-arc" to pop-up window.

I had encountered this situation in using "Reachibility" files.

This is shown in below figure :

If you change a little the question to ask about 2 assembly registers instead of variables, you can use also the xchg operation as one option, and the stack operation as another one.

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):

letsago = "ID" + str(self.dirDesc.values())

However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:

>>>str({'a':1}.values())
'dict_values([1])'

If you REALLY needed to find the variable this way, you could use the eval function:

>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'

or the globals function:

class Foo(object):
    def __init__(self):
        super(Foo, self).__init__()
    def test(self, name):
        print(globals()[name])

foo = Foo()
bar = 'Hello World!'
foo.text('bar')

However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.

The following code worked for me:

$result=DB::table('tablename')
->whereIn('columnName',function ($query) {
                $query->select('columnName2')->from('tableName2')
                ->Where('columnCondition','=','valueRequired');

            })
->get();

In Python 3.+ with the Signature object at hand, an easy way to get a mapping between argument names to values, is using the Signature's bind() method!

For example, here is a decorator for printing a map like that:

import inspect

def decorator(f):
    def wrapper(*args, **kwargs):
        bound_args = inspect.signature(f).bind(*args, **kwargs)
        bound_args.apply_defaults()
        print(dict(bound_args.arguments))

        return f(*args, **kwargs)

    return wrapper

@decorator
def foo(x, y, param_with_default="bars", **kwargs):
    pass

foo(1, 2, extra="baz")
# This will print: {'kwargs': {'extra': 'baz'}, 'param_with_default': 'bars', 'y': 2, 'x': 1}

I'm using Debian, and I was unable to use tilde for the path. Originally I was using

curl -c "~/cookie" http://localhost:5000/login -d username=myname password=mypassword

I had to change this to:

curl -c "/tmp/cookie" http://localhost:5000/login -d username=myname password=mypassword

-c creates the cookie, -b uses the cookie

so then I'd use for instance:

curl -b "/tmp/cookie" http://localhost:5000/getData

index=1
value=2
awk -F"," -v i=$index -v v=$value '$(i)==v' file

If you need to change the path, add this after your .config in your app file. Then you can do $location.path('/sampleurl', false); to prevent reloading

app.run(['$route', '$rootScope', '$location', function ($route, $rootScope, $location) {
    var original = $location.path;
    $location.path = function (path, reload) {
        if (reload === false) {
            var lastRoute = $route.current;
            var un = $rootScope.$on('$locationChangeSuccess', function () {
                $route.current = lastRoute;
                un();
            });
        }
        return original.apply($location, [path]);
    };
}])

Credit goes to https://www.consolelog.io/angularjs-change-path-without-reloading for the most elegant solution I've found.

If the API says to use HTTP Basic authentication, then you need to add an Authorization header to your request. I'd alter your code to look like this:

    WebRequest req = WebRequest.Create(@"https://sub.domain.com/api/operations?param=value&param2=value");
    req.Method = "GET";
    req.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes("username:password"));
    //req.Credentials = new NetworkCredential("username", "password");
    HttpWebResponse resp = req.GetResponse() as HttpWebResponse;

Replacing "username" and "password" with the correct values, of course.

I had the same issue on OSX Mavericks, it turned out that Sophos anti-virus was blocking certain requests, once I uninstalled it the issue went away.

If you think that it might be caused by an extension one easy way to try and test this is to open chrome with the '--disable-extensions flag to see if it fixes the problem. If that doesn't fix it consider looking beyond the browser to see if any other application might be causing the problem, specifically security apps which can affect requests.

Using the getBytes method, giving it the appropriate Charset (or Charset name).

Example:

String s = "Hello, there.";
byte[] b = s.getBytes(StandardCharsets.US_ASCII);

(Before Java 7: byte[] b = s.getBytes("US-ASCII");)

You may want to check out the jblas project. It's a relatively new Java library that uses BLAS, LAPACK and ATLAS for high-performance matrix operations.

The developer has posted some benchmarks in which jblas comes off favourably against MTJ and Colt.

Ok, for me that work with this...

var e2key = function(e) {
    if (!e) return '';
    var event2key = {
        '96':'0', '97':'1', '98':'2', '99':'3', '100':'4', '101':'5', '102':'6', '103':'7', '104':'8', '105':'9', // Chiffres clavier num
        '48':'m0', '49':'m1', '50':'m2', '51':'m3', '52':'m4', '53':'m5', '54':'m6', '55':'m7', '56':'m8', '57':'m9', // Chiffres caracteres speciaux
        '65':'a', '66':'b', '67':'c', '68':'d', '69':'e', '70':'f', '71':'g', '72':'h', '73':'i', '74':'j', '75':'k', '76':'l', '77':'m', '78':'n', '79':'o', '80':'p', '81':'q', '82':'r', '83':'s', '84':'t', '85':'u', '86':'v', '87':'w', '88':'x', '89':'y', '90':'z', // Alphabet
        '37':'left', '39':'right', '38':'up', '40':'down', '13':'enter', '27':'esc', '32':'space', '107':'+', '109':'-', '33':'pageUp', '34':'pageDown' // KEYCODES
    };
    return event2key[(e.which || e.keyCode)];
};

var page5Key = function(e, customKey) {
    if (e) e.preventDefault();
    switch(e2key(customKey || e)) {
        case 'left': /*...*/ break;
        case 'right': /*...*/ break;
    }
};

$(document).bind('keyup', page5Key);

$(document).trigger('keyup', [{preventDefault:function(){},keyCode:37}]); 

On windows and Netbeans you can set the relative path as:

    new FileReader("src\\PACKAGE_NAME\\FILENAME");

On Linux and Netbeans you can set the relative path as:

    new FileReader("src/PACKAGE_NAME/FILENAME");

If you have your code inside Source Packages I do not know if it is the same for eclipse or other IDE

I'd like to add a mention of the "brew" package. You can write a brew template file which would be LaTeX with placeholders, and then "brew" it up to create a .tex file to \include or \input into your LaTeX. Something like:

\begin{tabular}{l l}
A & <%= fit$A %> \\
B & <%= fit$B %> \\
\end{tabular}

The brew syntax can also handle loops, so you can create a table row for each row of a dataframe.

Try this:

.greenText{ background-color:green; }_x000D_
_x000D_
.blueText{ background-color:blue; }_x000D_
_x000D_
.redText{ background-color:red; }

<select_x000D_
    onchange="this.className=this.options[this.selectedIndex].className"_x000D_
    class="greenText">_x000D_
     <option class="greenText" value="apple" >Apple</option>_x000D_
    <option class="redText"   value="banana" >Banana</option>_x000D_
    <option class="blueText" value="grape" >Grape</option>_x000D_
</select>

You don't need to change the delimiter to display the right part of the string with cut.

The -f switch of the cut command is the n-TH element separated by your delimiter : :, so you can just type :

 grep puddle2_1557936 | cut -d ":" -f2

Another solutions (adapt it a bit) if you want fun :

Using grep :

grep -oP 'puddle2_1557936:\K.*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                        
/home/rogers.williams/folderz/puddle2

or still with look around regex

grep -oP '(?<=puddle2_1557936:).*' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                                    
/home/rogers.williams/folderz/puddle2

or with perl :

perl -lne '/puddle2_1557936:(.*)/ and print $1' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'                                                      
/home/rogers.williams/folderz/puddle2

or using ruby (thanks to glenn jackman)

ruby -F: -ane '/puddle2_1557936/ and puts $F[1]' <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with awk :

awk -F'puddle2_1557936:' '{print $2}'  <<< 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or with python :

python -c 'import sys; print(sys.argv[1].split("puddle2_1557936:")[1])' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
/home/rogers.williams/folderz/puddle2

or using only bash :

IFS=: read _ a <<< "puddle2_1557936:/home/rogers.williams/folderz/puddle2"
echo "$a"
/home/rogers.williams/folderz/puddle2

or using js in a shell :

js<<EOF
var x = 'puddle2_1557936:/home/rogers.williams/folderz/puddle2'
print(x.substr(x.indexOf(":")+1))
EOF
/home/rogers.williams/folderz/puddle2

or using php in a shell :

php -r 'preg_match("/puddle2_1557936:(.*)/", $argv[1], $m); echo "$m[1]\n";' 'puddle2_1557936:/home/rogers.williams/folderz/puddle2' 
/home/rogers.williams/folderz/puddle2

This is an example to read and write binary jjpg or wmv video file. FILE *fout; FILE *fin;

Int ch;
char *s;
fin=fopen("D:\\pic.jpg","rb");
if(fin==NULL)
     {  printf("\n Unable to open the file ");
         exit(1);
      }

 fout=fopen("D:\\ newpic.jpg","wb");
 ch=fgetc(fin);
       while (ch!=EOF)
             { 
                  s=(char *)ch;
                  printf("%c",s);
                 ch=fgetc (fin):
                 fputc(s,fout);
                 s++;
              }

        printf("data read and copied");
        fclose(fin);
        fclose(fout);

Different solution that I find more elegant

Here's another way to do it. Some people will prefer this as the code is a bit cleaner. There are no %s and a RESET color to end the coloration.

#include <stdio.h>

#define RED   "\x1B[31m"
#define GRN   "\x1B[32m"
#define YEL   "\x1B[33m"
#define BLU   "\x1B[34m"
#define MAG   "\x1B[35m"
#define CYN   "\x1B[36m"
#define WHT   "\x1B[37m"
#define RESET "\x1B[0m"

int main() {
  printf(RED "red\n"     RESET);
  printf(GRN "green\n"   RESET);
  printf(YEL "yellow\n"  RESET);
  printf(BLU "blue\n"    RESET);
  printf(MAG "magenta\n" RESET);
  printf(CYN "cyan\n"    RESET);
  printf(WHT "white\n"   RESET);

  return 0;
}

This program gives the following output:

Simple example with multiple colors

This way, it's easy to do something like:

printf("This is " RED "red" RESET " and this is " BLU "blue" RESET "\n");

This line produces the following output:

Here what you can try:

var d = Date.parse("2016-07-19T20:23:01.804Z");
alert(d); //this is in milliseconds

Assume we are creating a subsite whose files are in the folder http://site.ru/shop.

1. Absolute URL

Link to home page
href="http://sites.ru/shop/"

Link to the product page
href="http://sites.ru/shop/t-shirts/t-shirt-life-is-good/"

2. Relative URL

Link from home page to product page
href="t-shirts/t-shirt-life-is-good/"

Link from product page to home page
href="../../"

Although relative URL look shorter than absolute one, but the absolute URLs are more preferable, since a link can be used unchanged on any page of site.

Intermediate cases

We have considered two extreme cases: "absolutely" absolute and "absolutely" relative URLs. But everything is relative in this world. This also applies to URLs. Every time you say about absolute URL, you should always specify relative to what.

3. Protocol-relative URL

Link to home page
href="//sites.ru/shop/"

Link to product page
href="//sites.ru/shop/t-shirts/t-shirt-life-is-good/"

Google recommends such URL. Now, however, it is generally considered that http:// and https:// are different sites.

4. Root-relative URL

I.e. relative to the root folder of the domain.

Link to home page
href="/shop/"

Link to product page

It is a good choice if all pages are within the same domain. When you move your site to another domain, you don't have to do a mass replacements of the domain name in the URLs.

5. Base-relative URL (home-page-relative)

The tag <base> specifies the base URL, which is automatically added to all relative links and anchors. The base tag does not affect absolute links. As a base URL we'll specify the home page: <base href="http://sites.ru/shop/">.

Link to home page
href=""

Link to product page
href="t-shirts/t-shirt-life-is-good/"

Now you can move your site not only to any domain, but in any subfolder. Just keep in mind that, although URLs look like relative, in fact they are absolute. Especially pay attention to anchors. To navigate within the current page we have to write href="t-shirts/t-shirt-life-is-good/#comments" not href="#comments". The latter will throw on home page.

Conclusion

For internal links I use base-relative URLs (5). For external links and newsletters I use absolute URLs (1).

Similar to the answer pointed out by @Thomas, This can also be done using ifelse() method of R:

for(i in 1:ncol(data)){
  data[,i]=ifelse(is.na(data[,i]),
                  ave(data[,i],FUN=function(y) mean(y, na.rm = TRUE)),
                  data[,i])
}

where, Arguments to ifelse(TEST, YES , NO) are:-

TEST- logical condition to be checked

YES- executed if the condition is True

NO- else when the condition is False

and ave(x, ..., FUN = mean) is method in R used for calculating averages of subsets of x[]

Answer by Paul is right, I am just putting the visual to easily get there.

Set the checkbox marked in red and it will download the pdb files from microsoft. When you set the checkbox, it will also set a default path for the pdb files in the edit box under, you don't need to change that.

"If you start an android Service with startService(..) that Service will remain running until you explicitly invoke stopService(..). There are two reasons that a service can be run by the system. If someone calls Context.startService() then the system will retrieve the service (creating it and calling its onCreate() method if needed) and then call its onStartCommand(Intent, int, int) method with the arguments supplied by the client. The service will at this point continue running until Context.stopService() or stopSelf() is called. Note that multiple calls to Context.startService() do not nest (though they do result in multiple corresponding calls to onStartCommand()), so no matter how many times it is started a service will be stopped once Context.stopService() or stopSelf() is called; however, services can use their stopSelf(int) method to ensure the service is not stopped until started intents have been processed.

Clients can also use Context.bindService() to obtain a persistent connection to a service. This likewise creates the service if it is not already running (calling onCreate() while doing so), but does not call onStartCommand(). The client will receive the IBinder object that the service returns from its onBind(Intent) method, allowing the client to then make calls back to the service. The service will remain running as long as the connection is established (whether or not the client retains a reference on the Service's IBinder). Usually the IBinder returned is for a complex interface that has been written in AIDL.

A service can be both started and have connections bound to it. In such a case, the system will keep the service running as long as either it is started or there are one or more connections to it with the Context.BIND_AUTO_CREATE flag. Once neither of these situations hold, the Service's onDestroy() method is called and the service is effectively terminated. All cleanup (stopping threads, unregistering receivers) should be complete upon returning from onDestroy()."

Updated Answer:

Since some of the classes, in the original answer, are deprecated in the newer version of Apache HTTP Components, I'm posting this update.

By the way, you can access the full documentation for more examples here.

HttpClient httpclient = HttpClients.createDefault();
HttpPost httppost = new HttpPost("http://www.a-domain.com/foo/");

// Request parameters and other properties.
List<NameValuePair> params = new ArrayList<NameValuePair>(2);
params.add(new BasicNameValuePair("param-1", "12345"));
params.add(new BasicNameValuePair("param-2", "Hello!"));
httppost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));

//Execute and get the response.
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();

if (entity != null) {
    try (InputStream instream = entity.getContent()) {
        // do something useful
    }
}

Original Answer:

I recommend to use Apache HttpClient. its faster and easier to implement.

HttpPost post = new HttpPost("http://jakarata.apache.org/");
NameValuePair[] data = {
    new NameValuePair("user", "joe"),
    new NameValuePair("password", "bloggs")
};
post.setRequestBody(data);
// execute method and handle any error responses.
...
InputStream in = post.getResponseBodyAsStream();
// handle response.

Answer suggested by @Stacy Simpson:

We are struggling with the issue described in these threads and none of the resolutions seem to work:

• Stop "developer tools access needs to take control of another process for debugging to continue" alert
• Authorize a non-admin developer in Xcode / Mac OS

As I'm new to SO, I cannot post in either thread. (The first one is actually closed and I disagree with the localization reasoning...)

Anyway, we created a work-around using AppleScript that folks may be interested in. The script below should be executed asynchronously prior to launching your automated test:

osascript <script name> <password> &

Here is the script:

on run argv
    # Delay for 10 seconds as this script runs asynchronously to the automation process and is kicked off first.
    delay 10

    # Inspect all running processes
    tell application "System Events"
        set ProcessList to name of every process
        # Determine if authentication is being requested
        if "SecurityAgent" is in ProcessList then
            # Bring this dialogue to the front
            tell application "SecurityAgent" to activate
            # Enter provided password
            keystroke item 1 of argv
            keystroke return
        end if
    end tell
end run

Probably not very secure, but it's the best work-around we've come up with to allow tests to run without requiring user intervention.

Hopefully, I can get enough points to post the answer; or, someone can unprotect this question. Regards.

I know it's an old question now but i thought it might help others. I wanted something a little easier to implement for a few apps i had, so i made a class for this. You can download it here if you want: https://github.com/sdernley/iOSTextFieldHandler

It's as simple as setting all of the UITextFields to have a delegate of self

textfieldname.delegate = self;

And then adding this to your view controller with the name of your scrollView and submit button

- (void)textFieldDidBeginEditing:(UITextField *)textField
{
    [iOSTextFieldHandler TextboxKeyboardMover:containingScrollView tf:textField btn:btnSubmit];
}

Instead of handcranking your models try using something like the Json2csharp.com website. Paste In an example JSON response, the fuller the better and then pull in the resultant generated classes. This, at least, takes away some moving parts, will get you the shape of the JSON in csharp giving the serialiser an easier time and you shouldnt have to add attributes.

Just get it working and then make amendments to your class names, to conform to your naming conventions, and add in attributes later.

EDIT: Ok after a little messing around I have successfully deserialised the result into a List of Job (I used Json2csharp.com to create the class for me)

public class Job
{
        public string id { get; set; }
        public string position_title { get; set; }
        public string organization_name { get; set; }
        public string rate_interval_code { get; set; }
        public int minimum { get; set; }
        public int maximum { get; set; }
        public string start_date { get; set; }
        public string end_date { get; set; }
        public List<string> locations { get; set; }
        public string url { get; set; }
}

And an edit to your code:

        List<Job> model = null;
        var client = new HttpClient();
        var task = client.GetAsync("http://api.usa.gov/jobs/search.json?query=nursing+jobs")
          .ContinueWith((taskwithresponse) =>
          {
              var response = taskwithresponse.Result;
              var jsonString = response.Content.ReadAsStringAsync();
              jsonString.Wait();
              model = JsonConvert.DeserializeObject<List<Job>>(jsonString.Result);

          });
        task.Wait();

This means you can get rid of your containing object. Its worth noting that this isn't a Task related issue but rather a deserialisation issue.

EDIT 2:

There is a way to take a JSON object and generate classes in Visual Studio. Simply copy the JSON of choice and then Edit> Paste Special > Paste JSON as Classes. A whole page is devoted to this here:

http://blog.codeinside.eu/2014/09/08/Visual-Studio-2013-Paste-Special-JSON-And-Xml/

A single line method within bash works like this.

[some out put] >$(date "+%Y.%m.%d-%H.%M.%S").ver

will create a file with a timestamp name with ver extension. A working file listing snap shot to a date stamp file name as follows can show it working.

find . -type f -exec ls -la {} \; | cut -d ' ' -f 6- >$(date "+%Y.%m.%d-%H.%M.%S").ver

Of course

cat somefile.log > $(date "+%Y.%m.%d-%H.%M.%S").ver

or even simpler

ls > $(date "+%Y.%m.%d-%H.%M.%S").ver

You had a unescaped " in the onclick handler, escape it with \"

$('#contentData').append("<div class='media'><div class='media-body'><h4 class='media-heading'>" + v.Name + "</h4><p>" + v.Description + "</p><a class='btn' href='" + type + "'  onclick=\"(canLaunch('" + v.LibraryItemId + " '))\">View &raquo;</a></div></div>")

In general, if you have your coins COIN[] and your "change range" 1..MAX, the following should find the maximum number of coins.

Initialise array CHANGEVAL[MAX] to -1

For each element coin in COIN:
  set CHANGEVAL[coin] to 1
Until there are no more -1 in CHANGEVAL:
  For each index I over CHANGEVAL:
    if CHANGEVAL[I] != -1:
      let coincount = CHANGEVAL[I]
      For each element coin in COIN:
        let sum = coin + I
        if (COINS[sum]=-1) OR ((coincount+1)<COINS[sum]):
          COINS[sum]=coincount+1

I don't know if the check for coin-minimality in the inner conditional is, strictly speaking, necessary. I would think that the minimal chain of coin-additions would end up being correct, but better safe than sorry.

Might not be completely relevant to the question. But maybe can help someone.

Center Screen non of the above work for me. Reason was I was adding controls dynamically to the form. Technically when it centered it was correct , based on the form before adding the controls.

So here was my solution. ( Should work with both scenarios )

int x = Screen.PrimaryScreen.Bounds.Width - this.PreferredSize.Width;
int y = Screen.PrimaryScreen.Bounds.Height - this.PreferredSize.Height;

this.Location = new Point(x / 2, y / 2);

So you will notice that I am using "PreferredSize" instead of just using Height / Width. The preferred size will hold the value of the form after adding the controls. Where Height / Width won't.

Hope this helps someone .

If the delete is recent enough (Like an Oh-NO! moment) you should still have a message:

Deleted branch <branch name> (was abcdefghi).

you can still run:

git checkout abcdefghi

git checkout -b <some new branch name or the old one>

Simple, just use .set_color

>>> barlist=plt.bar([1,2,3,4], [1,2,3,4])
>>> barlist[0].set_color('r')
>>> plt.show()

For your new question, not much harder either, just need to find the bar from your axis, an example:

>>> f=plt.figure()
>>> ax=f.add_subplot(1,1,1)
>>> ax.bar([1,2,3,4], [1,2,3,4])
<Container object of 4 artists>
>>> ax.get_children()
[<matplotlib.axis.XAxis object at 0x6529850>, 
 <matplotlib.axis.YAxis object at 0x78460d0>,  
 <matplotlib.patches.Rectangle object at 0x733cc50>, 
 <matplotlib.patches.Rectangle object at 0x733cdd0>, 
 <matplotlib.patches.Rectangle object at 0x777f290>, 
 <matplotlib.patches.Rectangle object at 0x777f710>, 
 <matplotlib.text.Text object at 0x7836450>, 
 <matplotlib.patches.Rectangle object at 0x7836390>, 
 <matplotlib.spines.Spine object at 0x6529950>, 
 <matplotlib.spines.Spine object at 0x69aef50>,
 <matplotlib.spines.Spine object at 0x69ae310>, 
 <matplotlib.spines.Spine object at 0x69aea50>]
>>> ax.get_children()[2].set_color('r') 
 #You can also try to locate the first patches.Rectangle object 
 #instead of direct calling the index.

If you have a complex plot and want to identify the bars first, add those:

>>> import matplotlib
>>> childrenLS=ax.get_children()
>>> barlist=filter(lambda x: isinstance(x, matplotlib.patches.Rectangle), childrenLS)
[<matplotlib.patches.Rectangle object at 0x3103650>, 
 <matplotlib.patches.Rectangle object at 0x3103810>, 
 <matplotlib.patches.Rectangle object at 0x3129850>, 
 <matplotlib.patches.Rectangle object at 0x3129cd0>, 
 <matplotlib.patches.Rectangle object at 0x3112ad0>]

You can use the IndexOf method, which has a suitable overload for string comparison types:

if (def.IndexOf("s", StringComparison.OrdinalIgnoreCase) >= 0) ...

Also, you would not need the == true, since an if statement only expects an expression that evaluates to a bool.

You need to use an undocumented trick with Excel's LINEST function:

=LINEST(known_y's, [known_x's], [const], [stats])

Background

A regular linear regression is calculated (with your data) as:

=LINEST(B2:B21,A2:A21)

which returns a single value, the linear slope (m) according to the formula:

which for your data:

is:

Undocumented trick Number 1

You can also use Excel to calculate a regression with a formula that uses an exponent for x different from 1, e.g. x^1.2:

using the formula:

=LINEST(B2:B21, A2:A21^1.2)

which for you data:

is:

You're not limited to one exponent

Excel's LINEST function can also calculate multiple regressions, with different exponents on x at the same time, e.g.:

=LINEST(B2:B21,A2:A21^{1,2})

Note: if locale is set to European (decimal symbol ","), then comma should be replaced by semicolon and backslash, i.e. =LINEST(B2:B21;A2:A21^{1\2})

Now Excel will calculate regressions using both x¹ and x² at the same time:

How to actually do it

The impossibly tricky part there's no obvious way to see the other regression values. In order to do that you need to:

• select the cell that contains your formula:

  

• extend the selection the left 2 spaces (you need the select to be at least 3 cells wide):

  

• press F2

• press Ctrl+Shift+Enter

  

You will now see your 3 regression constants:

  y = -0.01777539x^2 + 6.864151123x + -591.3531443

Bonus Chatter

I had a function that I wanted to perform a regression using some exponent:

y = m×x^k + b

But I didn't know the exponent. So I changed the LINEST function to use a cell reference instead:

=LINEST(B2:B21,A2:A21^F3, true, true)

With Excel then outputting full stats (the 4th paramter to LINEST):

I tell the Solver to maximize R²:

And it can figure out the best exponent. Which for you data:

is:

Another solution is to user axios:

npm install axios

Code will be like:

const url = `${this.env.someMicroservice.address}/v1/my-end-point`;

const { data } = await axios.get<MyInterface>(url, {
  auth: {
    username: this.env.auth.user,
    password: this.env.auth.pass
  }
});

return data;

Just wanted to add -- apparently this can also be caused by installing Instant Client for 10, then realizing you want the full install and installing it again in a parallel directory. I don't know why this broke it.

Most of the posts that I found will timeout after a second iteration. Particularly if you are looping through a bunch if images as I have been. So to improve the suggestions above here is the entire method:

public System.Drawing.Image DownloadImage(string imageUrl)
    {
        System.Drawing.Image image = null;

        try
        {
            System.Net.HttpWebRequest webRequest = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(imageUrl);
            webRequest.AllowWriteStreamBuffering = true;
            webRequest.Timeout = 30000;
            webRequest.ServicePoint.ConnectionLeaseTimeout = 5000;
            webRequest.ServicePoint.MaxIdleTime = 5000;

            using (System.Net.WebResponse webResponse = webRequest.GetResponse())
            {

                using (System.IO.Stream stream = webResponse.GetResponseStream())
                {
                    image = System.Drawing.Image.FromStream(stream);
                }
            }

            webRequest.ServicePoint.CloseConnectionGroup(webRequest.ConnectionGroupName);
            webRequest = null; 
        }
        catch (Exception ex)
        {
            throw new Exception(ex.Message, ex);

        }


        return image;
    }

You might also consider using a build tool like Maven to manage your dependencies. It is very easy to setup and helps manage those dependencies automatically in eclipse. Definitely worth the effort if you have a large project with a lot of external dependencies.

Here is a simple example taken from 'Modern C++ Design - Generic Programming and Design Patterns Applied' by Andrei Alexandrescu:

He uses a classes with template template parameters in order to implement the policy pattern:

// Library code
template <template <class> class CreationPolicy>
class WidgetManager : public CreationPolicy<Widget>
{
   ...
};

He explains: Typically, the host class already knows, or can easily deduce, the template argument of the policy class. In the example above, WidgetManager always manages objects of type Widget, so requiring the user to specify Widget again in the instantiation of CreationPolicy is redundant and potentially dangerous.In this case, library code can use template template parameters for specifying policies.

The effect is that the client code can use 'WidgetManager' in a more elegant way:

typedef WidgetManager<MyCreationPolicy> MyWidgetMgr;

Instead of the more cumbersome, and error prone way that a definition lacking template template arguments would have required:

typedef WidgetManager< MyCreationPolicy<Widget> > MyWidgetMgr;

In order to add a label to the map you need to create a custom overlay. The sample at http://blog.mridey.com/2009/09/label-overlay-example-for-google-maps.html uses a custom class, Layer, that inherits from OverlayView (which inherits from MVCObject) from the Google Maps API. He has a revised version (adds support for visibility, zIndex and a click event) which can be found here: http://blog.mridey.com/2011/05/label-overlay-example-for-google-maps.html

The following code is taken directly from Marc Ridey's Blog (the revised link above).

Layer class

// Define the overlay, derived from google.maps.OverlayView
function Label(opt_options) {
  // Initialization
  this.setValues(opt_options);


  // Label specific
  var span = this.span_ = document.createElement('span');
  span.style.cssText = 'position: relative; left: -50%; top: -8px; ' +
  'white-space: nowrap; border: 1px solid blue; ' +
  'padding: 2px; background-color: white';


  var div = this.div_ = document.createElement('div');
  div.appendChild(span);
  div.style.cssText = 'position: absolute; display: none';
};
Label.prototype = new google.maps.OverlayView;


// Implement onAdd
Label.prototype.onAdd = function() {
  var pane = this.getPanes().overlayImage;
  pane.appendChild(this.div_);


  // Ensures the label is redrawn if the text or position is changed.
  var me = this;
  this.listeners_ = [
    google.maps.event.addListener(this, 'position_changed', function() { me.draw(); }),
    google.maps.event.addListener(this, 'visible_changed', function() { me.draw(); }),
    google.maps.event.addListener(this, 'clickable_changed', function() { me.draw(); }),
    google.maps.event.addListener(this, 'text_changed', function() { me.draw(); }),
    google.maps.event.addListener(this, 'zindex_changed', function() { me.draw(); }),
    google.maps.event.addDomListener(this.div_, 'click', function() {
      if (me.get('clickable')) {
        google.maps.event.trigger(me, 'click');
      }
    })
  ];
};

// Implement onRemove
Label.prototype.onRemove = function() {
 this.div_.parentNode.removeChild(this.div_);

 // Label is removed from the map, stop updating its position/text.
 for (var i = 0, I = this.listeners_.length; i < I; ++i) {
   google.maps.event.removeListener(this.listeners_[i]);
 }
};

// Implement draw
Label.prototype.draw = function() {
 var projection = this.getProjection();
 var position = projection.fromLatLngToDivPixel(this.get('position'));

 var div = this.div_;
 div.style.left = position.x + 'px';
 div.style.top = position.y + 'px';
 div.style.display = 'block';

 this.span_.innerHTML = this.get('text').toString();
};

  );

exports.onInstanceDelete = functions.firestore.document('projects/{projectId}/instances/{instanceId}')
  .onDelete((snap, context) =>
    db.collection('projects').doc(context.params.projectId).update({
      instanceCount: admin.firestore.FieldValue.increment(-1),
    })
  );

In this example we increment an instanceCount field in the project each time a document is added to the instances sub collection. If the field doesn't exist yet it will be created and incremented to 1.

The incrementation is transactional internally but you should use a distributed counter if you need to increment more frequently than every 1 second.

It's often preferable to implement onCreate and onDelete rather than onWrite as you will call onWrite for updates which means you are spending more money on unnecessary function invocations (if you update the docs in your collection).

I was interested in this as well and came across some examples on the Spring Boot site.

   // get with query string parameters e.g. /system/resource?id="rtze1cd2"&person="sam smith" 
// so below the first query parameter id is the variable and name is the variable
// id is shown below as a RequestParam
    @GetMapping("/system/resource")
    // this is for swagger docs
    @ApiOperation(value = "Get the resource identified by id and person")
    ResponseEntity<?> getSomeResourceWithParameters(@RequestParam String id, @RequestParam("person") String name) {

        InterestingResource resource = getMyInterestingResourc(id, name);
        logger.info("Request to get an id of "+id+" with a name of person: "+name);

        return new ResponseEntity<Object>(resource, HttpStatus.OK);
    }

Reproducing tim_yates answer on current hardware and adding leftShift() and concat() method to check the finding:

  'String leftShift' {
    foo << bar << baz
  }
  'String concat' {
    foo.concat(bar)
       .concat(baz)
       .toString()
  }

The outcome shows concat() to be the faster solution for a pure String, but if you can handle GString somewhere else, GString template is still ahead, while honorable mention should go to leftShift() (bitwise operator) and StringBuffer() with initial allocation:

This problem is due to the https protocol, which is why the other solution works (by switching to the non-secure protocol).

For me, the best solution was to compile the latest version of node, which includes npm

apt-get purge nodejs npm
git clone https://github.com/nodejs/node ~/local/node
cd ~/local/node
./configure
make
make install

Instead of creating a blacklist of characters, you could use a whitelist. All things considered, the range of characters that make sense in a file or directory name context is quite short, and unless you have some very specific naming requirements your users will not hold it against your application if they cannot use the whole ASCII table.

It does not solve the problem of reserved names in the target file system, but with a whitelist it is easier to mitigate the risks at the source.

In that spirit, this is a range of characters that can be considered safe:

• Letters (a-z A-Z) - Unicode characters as well, if needed
• Digits (0-9)
• Underscore (_)
• Hyphen (-)
• Space
• Dot (.)

And any additional safe characters you wish to allow. Beyond this, you just have to enforce some additional rules regarding spaces and dots. This is usually sufficient:

• Name must contain at least one letter or number (to avoid only dots/spaces)
• Name must start with a letter or number (to avoid leading dots/spaces)
• Name may not end with a dot or space (simply trim those if present, like Explorer does)

This already allows quite complex and nonsensical names. For example, these names would be possible with these rules, and be valid file names in Windows/Linux:

• A...........ext
• B -.- .ext

In essence, even with so few whitelisted characters you should still decide what actually makes sense, and validate/adjust the name accordingly. In one of my applications, I used the same rules as above but stripped any duplicate dots and spaces.

I faced this issue, and that is when a Bean (@Bean) was not instantiated properly as it was not given the correct parameters in my test class.

Indeed simplest way. Don't bother with changing the headers.

Make sure you have:

<%= csrf_meta_tag %> in your layouts/application.html.erb

Just do a hidden input field like so:

<input name="authenticity_token" 
               type="hidden" 
               value="<%= form_authenticity_token %>"/>

Or if you want a jQuery ajax post:

$.ajax({     
    type: 'POST',
    url: "<%= someregistration_path %>",
    data: { "firstname": "text_data_1", "last_name": "text_data2", "authenticity_token": "<%= form_authenticity_token %>" },                                                                                  
    error: function( xhr ){ 
      alert("ERROR ON SUBMIT");
    },
    success: function( data ){ 
      //data response can contain what we want here...
      console.log("SUCCESS, data="+data);
    }
});

I run into this issue too. I was including bootstrap.js AND bootstrap-modal.js. If you already have bootstrap.js, you don't need to include popover.

setSize() or setBounds() can be used when no layout manager is being used.

However, if you are using a layout manager you can provide hints to the layout manager using the setXXXSize() methods like setPreferredSize() and setMinimumSize() etc.

And be sure that the component's container uses a layout manager that respects the requested size. The FlowLayout, GridBagLayout, and SpringLayout managers use the component's preferred size (the latter two depending on the constraints you set), but BorderLayout and GridLayout usually don't.If you specify new size hints for a component that's already visible, you need to invoke the revalidate method on it to make sure that its containment hierarchy is laid out again. Then invoke the repaint method.

We can do it by using the below code snippet..

Angular Code:

 export class AppComponent {  
    toggleShowHide: string = "visible";  
 }

HTML Template:

  Enter text to hide or show item in bellow: 
  <input type="text" [(ngModel)]="toggleShowHide">
  <br>
  Toggle Show/hide:
  <div [style.visibility]="toggleShowHide">   
     Final Release Angular 2!
  </div>

<div class="row">
  <div class="col-4 alert alert-primary">
     1
  </div>
  <div class="col-8">
    <div class="row">
      <div class="col-6 alert alert-primary">
        2
      </div>
      <div class="col-6 alert alert-primary">
        3
      </div>
      <div class="col-6 alert alert-primary">
        4
      </div>
      <div class="col-6 alert alert-primary">
        5
      </div>
    </div>
  </div>
</div>
<div class="row">
  <div class="col-4 alert alert-primary">
    6
  </div>
  <div class="col-4 alert alert-primary">

  </div>
  <div class="col-4 alert alert-primary">
    8
  </div>
</div>

I guess you're searching for this custom function. It takes a data-toggle attribute and creates dynamically the necessary div to place the remote content. Just place the data-toggle="ajaxModal" on any link you want to load via AJAX.

The JS part:

$('[data-toggle="ajaxModal"]').on('click',
              function(e) {
                $('#ajaxModal').remove();
                e.preventDefault();
                var $this = $(this)
                  , $remote = $this.data('remote') || $this.attr('href')
                  , $modal = $('<div class="modal" id="ajaxModal"><div class="modal-body"></div></div>');
                $('body').append($modal);
                $modal.modal({backdrop: 'static', keyboard: false});
                $modal.load($remote);
              }
            );

Finally, in the remote content, you need to put the entire structure to work.

<div class="modal-dialog">
    <div class="modal-content">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal">&times;</button>
            <h4 class="modal-title"></h4>
        </div>
        <div class="modal-body">
        </div>
        <div class="modal-footer">
            <a href="#" class="btn btn-white" data-dismiss="modal">Close</a>
            <a href="#" class="btn btn-primary">Button</a>
            <a href="#" class="btn btn-primary">Another button...</a>
        </div>
    </div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->

To get proper (translatable) messages, currently using SF 2.6.3, here is my final function (as none of above's seem to work anymore):

 private function getErrorMessages(\Symfony\Component\Form\Form $form) {      
    $errors = array();
    foreach ($form->getErrors(true, false) as $error) {
        // My personnal need was to get translatable messages
        // $errors[] = $this->trans($error->current()->getMessage());
        $errors[] = $error->current()->getMessage();
    }

    return $errors;
}

as the Form::getErrors() method now returns an instance of FormErrorIterator, unless you switch the second argument ($flatten) to true. (It will then return a FormError instance, and you will have to call the getMessage() method directly, without the current() method:

 private function getErrorMessages(\Symfony\Component\Form\Form $form) {      
    $errors = array();
    foreach ($form->getErrors(true, true) as $error) {
        // My personnal need was to get translatable messages
        // $errors[] = $this->trans($error->getMessage());
        $errors[] = $error->getMessage();
    }

    return $errors;
}

)

The most important thing is actually to set the first argument to true in order to get the errors. Leaving the second argument ($flatten) to his default value (true) will return FormError instances, while it will return FormErrorIterator instances when set to false.

This did the trick for me:

var express = require('express'),
app = express(); 
app.use('/', express.static(__dirname + '/'));
app.listen(8080);

If you are using SE linux, set it to permissive mode by editing /etc/selinux/config and changing SELINUX=enforcing to SELINUX=permissive

Just an alternative:

ls -lAR | grep -v '^d' | awk '{total += $5} END {print "Total:", total}'

grep -v '^d' will exclude the directories.

If the body of the arrow function is wrapped in curly braces, it is not implicitly returned. Wrap the object in parentheses. It would look something like this.

p => ({ foo: 'bar' })

By wrapping the body in parens, the function will return { foo: 'bar }.

Hopefully, that solves your problem. If not, I recently wrote an article about Arrow functions which covers it in more detail. I hope you find it useful. Javascript Arrow Functions

Try this.

• On Windows do Ctrl + Alt + L
• On Linux do Ctrl + Shift + Alt + L for dialog to open and then reformat.
• On Mac do CMD + Alt + L

Note: Here many answers for Linux is just Ctrl + Alt + L which is wrong. In Linux, doing Ctrl + Alt + L locks the system.

Test like this.Sometimes, permission problem.

cmd => dcomcnfg

I write this answer because I was looking for a way to plot together the histograms of different groups. What follows is not very smart, but it works fine for me. I use Numpy to compute the histogram and Bokeh for plotting. I think it is self-explanatory, but feel free to ask for clarifications and I'll be happy to add details (and write it better).

figures = {
    'Transit': figure(title='Transit', x_axis_label='speed [km/h]', y_axis_label='frequency'),
    'Driving': figure(title='Driving', x_axis_label='speed [km/h]', y_axis_label='frequency')
}

cols = {'Vienna': 'red', 'Turin': 'blue', 'Rome': 'Orange'}
for gr in df_trips.groupby(['locality', 'means']):
    locality = gr[0][0]
    means = gr[0][1]
    fig = figures[means]
    h, b = np.histogram(pd.DataFrame(gr[1]).speed.values)
    fig.vbar(x=b[1:], top=h, width=(b[1]-b[0]), legend_label=locality, fill_color=cols[locality], alpha=0.5)

show(gridplot([
    [figures['Transit']],
    [figures['Driving']],
]))

That worked for me in WPF application:

string configPath = Path.Combine(System.Environment.CurrentDirectory, "YourApplication.exe");
Configuration config = ConfigurationManager.OpenExeConfiguration(configPath);
config.AppSettings.Settings["currentLanguage"].Value = "En";
config.Save();

you can try this:

date_default_timezone_set('Asia/Kolkata');

In application/config.php OR application/autoload.php

There is look like this:

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

date_default_timezone_set('Asia/Kolkata');

It's working fine for me, i think this is the best way to define DEFAULT TIMEZONE in codeignitor.

I know this question is about Linux, but in case someone stumbles on this problem on Mac like I did here is the solution for that. I had the exact same problem on Mac because ffmpeg is not installed by default apparently, and so I could solve it using:

brew install yasm
brew install ffmpeg

Try this set of code to download a CSV file from the server.

byte[] Content= File.ReadAllBytes(FilePath); //missing ;
Response.ContentType = "text/csv";
Response.AddHeader("content-disposition", "attachment; filename=" + fileName + ".csv");
Response.BufferOutput = true;
Response.OutputStream.Write(Content, 0, Content.Length);
Response.End();

Resync your project gradle files to add the app module through Gradle

1. In the root folder of your project, open the settings.gradle file for editing.

2. Cut line include ':app' from the file.

3. On Android Studio, click on the File Menu, and select Sync Project with Gradle files.

4. After synchronisation, paste back line include ':app' to the settings.gradle file.

5. Re-run Sync Project with Gradle files again.

If you want to speed up your query using join:

For "inner join/join", Don't use where condition instead use it in "ON" condition. Eg:

     select id,name from table1 a  
   join table2 b on a.name=b.name
   where id='123'

 Try,

    select id,name from table1 a  
   join table2 b on a.name=b.name and a.id='123'

For "Left/Right Join", Don't use in "ON" condition, Because if you use left/right join it will get all rows for any one table.So, No use of using it in "On". So, Try to use "Where" condition

You want the :checkbox:checked selector and map to create an array of the values:

var checkedValues = $('input:checkbox:checked').map(function() {
    return this.value;
}).get();

If your checkboxes have a shared class it would be faster to use that instead, eg. $('.mycheckboxes:checked'), or for a common name $('input[name="Foo"]:checked')

- Update -

If you don't need IE support then you can now make the map() call more succinct by using an arrow function:

var checkedValues = $('input:checkbox:checked').map((i, el) => el.value).get();

You're declaring everything in the parent page. So the references to window and document are to the parent page's. If you want to do stuff to the iframe's, use iframe || iframe.contentWindow to access its window, and iframe.contentDocument || iframe.contentWindow.document to access its document.

There's a word for what's happening, possibly "lexical scope": What is lexical scope?

The only context of a scope is this. And in your example, the owner of the method is doc, which is the iframe's document. Other than that, anything that's accessed in this function that uses known objects are the parent's (if not declared in the function). It would be a different story if the function were declared in a different place, but it's declared in the parent page.

This is how I would write it:

(function () {
  var dom, win, doc, where, iframe;

  iframe = document.createElement('iframe');
  iframe.src = "javascript:false";

  where = document.getElementsByTagName('script')[0];
  where.parentNode.insertBefore(iframe, where);

  win = iframe.contentWindow || iframe;
  doc = iframe.contentDocument || iframe.contentWindow.document;

  doc.open();
  doc._l = (function (w, d) {
    return function () {
      w.vanishing_global = new Date().getTime();

      var js = d.createElement("script");
      js.src = 'test-vanishing-global.js?' + w.vanishing_global;

      w.name = "foobar";
      d.foobar = "foobar:" + Math.random();
      d.foobar = "barfoo:" + Math.random();
      d.body.appendChild(js);
    };
  })(win, doc);
  doc.write('<body onload="document._l();"></body>');
  doc.close();
})();

The aliasing of win and doc as w and d aren't necessary, it just might make it less confusing because of the misunderstanding of scopes. This way, they are parameters and you have to reference them to access the iframe's stuff. If you want to access the parent's, you still use window and document.

I'm not sure what the implications are of adding methods to a document (doc in this case), but it might make more sense to set the _l method on win. That way, things can be run without a prefix...such as <body onload="_l();"></body>

You can define your own custom MarshalJSON and UnmarshalJSON methods and intentionally control what should be included, ex:

package main

import (
    "fmt"
    "encoding/json"
)

type User struct {
    name string
}

func (u *User) MarshalJSON() ([]byte, error) {
    return json.Marshal(&struct {
        Name     string `json:"name"`
    }{
        Name:     "customized" + u.name,
    })
}

func main() {
    user := &User{name: "Frank"}
    b, err := json.Marshal(user)
    if err != nil {
        fmt.Println(err)
        return
    }
    fmt.Println(string(b))
}

If you have a url and your php supports it, you could just call file_get_contents:

$response = file_get_contents('http://example.com/path/to/api/call?param1=5');

if $response is JSON, use json_decode to turn it into php array:

$response = json_decode($response);

if $response is XML, use simple_xml class:

$response = new SimpleXMLElement($response);

Here is a pretty simple stored procedure that does the trick as well...

    CREATE PROCEDURE GetBCPTable
    @table_name varchar(200)
AS
BEGIN
    DECLARE @raw_sql nvarchar(3000)

    DECLARE @columnHeader VARCHAR(8000)
    SELECT @columnHeader = COALESCE(@columnHeader+',' ,'')+ ''''+column_name +'''' FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @table_name

    DECLARE @ColumnList VARCHAR(8000)
    SELECT @ColumnList = COALESCE(@ColumnList+',' ,'')+ 'CAST('+column_name +' AS VARCHAR)' FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = @table_name

    SELECT @raw_sql = 'SELECT '+ @columnHeader +' UNION ALL SELECT ' + @ColumnList + ' FROM ' + @table_name
    --PRINT @raw_SQL
    EXECUTE sp_executesql  @raw_sql
END
GO

WebDriverWait wait = new WebDriverWait(driver,5)
wait.until(ExpectedConditions.visibilityOf(element));

You'll need different sized icons for iOS and Android, like Rockvic said. In addition, I recommend this site for generating different sized icons if anybody is interested. You don't need to download anything and it works perfectly.

Hope it helps.

The line (or lines) between the lines beginning <<<<<<< and ====== here:

<<<<<<< HEAD:file.txt
Hello world
=======

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

See ?merge:

the name "row.names" or the number 0 specifies the row names.

Example:

R> de <- merge(d, e, by=0, all=TRUE)  # merge by row names (by=0 or by="row.names")

Try more parameters one which will surely find and if available update and not then it will create new

$save_data= Model::firstOrNew(['key1' => $key1value,'key'=>$key2value]);
//your values here
$save_data->save();

From http://api.jquery.com/jQuery/

Selector Context By default, selectors perform their searches within the DOM starting at the document root. However, an alternate context can be given for the search by using the optional second parameter to the $() function. For example, to do a search within an event handler, the search can be restricted like so:

$( "div.foo" ).click(function() { 
   $( "span", this ).addClass( "bar" );
});

When the search for the span selector is restricted to the context of this, only spans within the clicked element will get the additional class.

So for your example I would suggest something like:

$("div", ".container").each(function(){
     //do whatever
 });

If you are using date-fns and if you dont want to install the Moment.js or the moment-precise-range-plugin. You can use the following date-fns function to get the same result as moment-precise-range-plugin

intervalToDuration({
  start: new Date(),
  end: new Date("24 Jun 2020")
})

This will give output in a JSON object like below

{
  "years": 0,
  "months": 0,
  "days": 0,
  "hours": 19,
  "minutes": 35,
  "seconds": 24
}

There's a lot of methods here that are hard to understand but basically all update the map when it's paused etc. There are also connection timeouts etc. Sorry for just posting this, I tried to fix your code but I couldn't figure out what was wrong.

If doing quoted answers, you can do

$commaList = '"'.implode( '" , " ', $fruit). '"';

the above assumes that fruit is non-null. If you don't want to make that assumption you can use an if-then-else statement or ternary (?:) operator.

Using appendEncodePath() could save you multiple lines than appendPath(), the following code snippet builds up this url: http://api.openweathermap.org/data/2.5/forecast/daily?zip=94043

Uri.Builder urlBuilder = new Uri.Builder();
urlBuilder.scheme("http");
urlBuilder.authority("api.openweathermap.org");
urlBuilder.appendEncodedPath("data/2.5/forecast/daily");
urlBuilder.appendQueryParameter("zip", "94043,us");
URL url = new URL(urlBuilder.build().toString());

Blockquote

    foreach (GridViewRow row in tempGrid.Rows)
    {
        dt.Rows.Add();
        for (int i = 0; i < row.Controls.Count; i++)
        {
            Control control = row.Controls[i];
            if (control.Controls.Count==1)
            {
                CheckBox chk = row.Cells[i].Controls[0] as CheckBox;
                if (chk != null && chk.Checked)
                {
                    dt.Rows[dt.Rows.Count - 1][i] = "True";
                }
                else
                dt.Rows[dt.Rows.Count - 1][i] = "False";
            }
            else
                dt.Rows[dt.Rows.Count - 1][i] = row.Cells[i].Text.Replace("&nbsp;", "");
        }
    }

std::string a = "Hello ";

If you have setup.py in your project and you use find_packages() within it, it is necessary to have an __init__.py file in every directory for packages to be automatically found.

Packages are only recognized if they include an __init__.py file

UPD: If you want to use implicit namespace packages without __init__.py you just have to use find_namespace_packages() instead

If I use exit() in a code and run it in the shell, it shows a message asking whether I want to kill the program or not. It's really disturbing. See here

But sys.exit() is better in this case. It closes the program and doesn't create any dialogue box.

When you return value from server to jQuery's Ajax call you can also use the below code to indicate a server error:

return StatusCode(500, "My error");

Or

return StatusCode((int)HttpStatusCode.InternalServerError, "My error");

Or

Response.StatusCode = (int)HttpStatusCode.InternalServerError;
return Json(new { responseText = "my error" });

Codes other than Http Success codes (e.g. 200[OK]) will trigger the function in front of error: in client side (ajax).

you can have ajax call like:

$.ajax({
        type: "POST",
        url: "/General/ContactRequestPartial",
        data: {
            HashId: id
        },
       success: function (response)  {
            console.log("Custom message : " + response.responseText);
        }, //Is Called when Status Code is 200[OK] or other Http success code
        error: function (jqXHR, textStatus, errorThrown)  {
            console.log("Custom error : " + jqXHR.responseText + " Status: " + textStatus + " Http error:" + errorThrown);
        }, //Is Called when Status Code is 500[InternalServerError] or other Http Error code
        })

Additionally you can handle different HTTP errors from jQuery side like:

$.ajax({
        type: "POST",
        url: "/General/ContactRequestPartial",
        data: {
            HashId: id
        },
        statusCode: {
            500: function (jqXHR, textStatus, errorThrown)  {
                console.log("Custom error : " + jqXHR.responseText + " Status: " + textStatus + " Http error:" + errorThrown);
            501: function (jqXHR, textStatus, errorThrown)  {
                console.log("Custom error : " + jqXHR.responseText + " Status: " + textStatus + " Http error:" + errorThrown);
            }
        })

statusCode: is useful when you want to call different functions for different status codes that you return from server.

You can see list of different Http Status codes here:Wikipedia

According to the latest version (1.5.3) there is no fromHTML() method anymore. Instead you should utilize jsPDF HTML plugin, see: https://rawgit.com/MrRio/jsPDF/master/docs/module-html.html#~html

You also need to add html2canvas library in order for it to work properly: https://github.com/niklasvh/html2canvas

JS (from API docs):

var doc = new jsPDF();   

doc.html(document.body, {
   callback: function (doc) {
     doc.save();
   }
});

You can provide HTML string instead of reference to the DOM element as well.

As an alternative option, could you use the "accept" attribute of HTML File Input which defines which MIME types are acceptable.

Definition here

I simple used Eval(string) and it evaluated as Double.

Like this:

document.getElementById('myTextarea').value = '';

or like this in jQuery:

$('#myTextarea').val('');

Where you have

<textarea id="myTextarea" name="something">This text gets removed</textarea>

For all the downvoters and non-believers:

• Here's the MSDN reference

  value Property: Retrieves or sets the text in the entry field of the textArea element.

• Here's the MDN reference

  value DOMString The raw value contained in the control.

For Jar

Add pom.xml

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

We can also use Python's reduce function:

from functools import reduce

sentence = ['this','is','a','sentence']
out_str = str(reduce(lambda x,y: x+"-"+y, sentence))
print(out_str)

After perusing your previous questions I eventually determined you are probably on SQL Server 2005. For US format you would use style 101

select Subject, 
       CONVERT(varchar,DeliveryDate,101) as DeliveryDate
from Email_Administration 
where MerchantId =@MerchantID 

If you know for sure that the element is present, you could try this to simulate the click - if .Click() isn't working

driver.findElement(By.name("submit")).sendKeys(Keys.RETURN);

or

driver.findElement(By.name("submit")).sendKeys(Keys.ENTER);

Get the router from the container.

$router = $this->get('router');

Then use the router to generate the Url

$uri = $router->generate('blog_show', array('slug' => 'my-blog-post'));

why making life hard-

PreparedStatement pstmt = conn.prepareStatement("select * from employee where id in ("+ StringUtils.join(arraylistParameter.iterator(),",") +)");

Open the hosts file located at : **C:\windows\system32\drivers\etc**.

Hosts file is for what?

Add the following at end of this file :

YourServerIP YourDNS

Example:

198.168.1.1 maps.google.com

Now, the sh step supports returning stdout by supplying the parameter returnStdout.

// These should all be performed at the point where you've
// checked out your sources on the slave. A 'git' executable
// must be available.
// Most typical, if you're not cloning into a sub directory
gitCommit = sh(returnStdout: true, script: 'git rev-parse HEAD').trim()
// short SHA, possibly better for chat notifications, etc.
shortCommit = gitCommit.take(6)

See this example.

Just add below lines in your POJO before start of class ,and your issue is resolved. @Produces("application/json") @XmlRootElement See example import javax.ws.rs.Produces; import javax.xml.bind.annotation.XmlRootElement;

 /**
 * @author manoj.kumar
 * @email [email protected]
 */
 @Produces("application/json")
 @XmlRootElement  
 public class User {

 private String username;
 private String password;
 private String email;
 public String getUsername() {
 return username;
 }
 public void setUsername(String username) {
     this.username = username;
 }
 public String getPassword() {
     return password;
 }
 public void setPassword(String password) {
     this.password = password;
 }
 public String getEmail() {
    return email;
 }
 public void setEmail(String email) {
    this.email = email;
 }

}
add below lines inside of your web.xml
<init-param>
    <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
    <param-value>true</param-value>
</init-param>  
Now recompile your webservice everything would work!!!

UPDATE: The stroke-alignment attribute was on April 1st, 2015 moved to a completely new spec called SVG Strokes.

As of the SVG 2.0 Editor’s Draft of February 26th, 2015 (and possibly since February 13th), the stroke-alignment property is present with the values inner, center (default) and outer.

It seems to work the same way as the stroke-location property proposed by @Phrogz and the later stroke-position suggestion. This property has been planned since at least 2011, but apart from an annotation that said

SVG 2 shall include a way to specify stroke position

, it has never been detailed in the spec as it was deferred - until now, it seems.

No browser support this property, or, as far as I know, any of the new SVG 2 features, yet, but hopefully they will soon as the spec matures. This has been a property I personally have been urging to have, and I'm really happy that it's finally there in the spec.

There seems to be some issues as to how to the property should behave on open paths as well as loops. These issues will, most probably, prolong implementations across browsers. However, I will update this answer with new information as browsers begin to support this property.

I'd like to add this is a solution to search multiple attributes of an ActiveRecord. Since

.where(A: param[:A], B: param[:B])

will search for A and B.

To get rid of vertical padding for a single line label I did:

// I have a category method setFrameHeight; you'll likely need to modify the frame.
[label setFrameHeight:font.pointSize];

OR, without the category, use:

CGRect frame = label.frame;
frame.size.height = font.pointSize;
label.frame = frame;

This is my solution with prepared statements and stored procedure is returning several rows not only one value.

<?php

require 'config.php';
header('Content-type:application/json');
$connection->set_charset('utf8');

$mIds = $_GET['ids'];

$stmt = $connection->prepare("CALL sp_takes_string_returns_table(?)");
$stmt->bind_param("s", $mIds);

$stmt->execute();

$result = $stmt->get_result();
$response = $result->fetch_all(MYSQLI_ASSOC);
echo json_encode($response);

$stmt->close();
$connection->close();

1. Where does user.id go after passport.serializeUser has been called?

The user id (you provide as the second argument of the done function) is saved in the session and is later used to retrieve the whole object via the deserializeUser function.

serializeUser determines which data of the user object should be stored in the session. The result of the serializeUser method is attached to the session as req.session.passport.user = {}. Here for instance, it would be (as we provide the user id as the key) req.session.passport.user = {id: 'xyz'}

2. We are calling passport.deserializeUser right after it where does it fit in the workflow?

The first argument of deserializeUser corresponds to the key of the user object that was given to the done function (see 1.). So your whole object is retrieved with help of that key. That key here is the user id (key can be any key of the user object i.e. name,email etc). In deserializeUser that key is matched with the in memory array / database or any data resource.

The fetched object is attached to the request object as req.user

Visual Flow

passport.serializeUser(function(user, done) {
    done(null, user.id);
});              ¦
                 ¦ 
                 ¦
                 +--------------------? saved to session
                                   ¦    req.session.passport.user = {id: '..'}
                                   ¦
                                   ?           
passport.deserializeUser(function(id, done) {
                   +---------------+
                   ¦
                   ? 
    User.findById(id, function(err, user) {
        done(err, user);
    });            +--------------? user object attaches to the request as req.user   
});

I have viewed all of the answers above but none of them is elegant enough for me. In Pycharm 2017.1.3(in my computer), the easiest way is to open Settings->Tools->Terminal and check Shell integration and Activate virtualenv options.

If the keystore is PKCS12 type (.pfx) you have to specify it with -storetype PKCS12 (line breaks added for readability):

keytool -list -v -keystore <path to keystore.pfx> \
    -storepass <password> \
    -storetype PKCS12

Step1:
npm install bootstrap@latest --save-dev This will install the latest version of the bootstrap, However, the specified version can be installed by adding the version number

Step2: Open styles.css and add the following @import "~bootstrap/dist/css/bootstrap.css"

Try the command

sudo mysql_secure_installation

press enter and assign a new password for root in mysql/mariadb.

If you get an error like

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'

enable the service with

service mysql start

now if you re-enter with

mysql -u root -p

if you follow the problem enter with sudo su and mysql -u root -p now apply permissions to root

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY '<password>';

this fixed my problem in MariaDB.

Good luck

Compression algorithms almost always have some form of space overhead, which means that they are only effective when compressing data which is sufficiently large that the overhead is smaller than the amount of saved space.

Compressing a string which is only 20 characters long is not too easy, and it is not always possible. If you have repetition, Huffman Coding or simple run-length encoding might be able to compress, but probably not by very much.

For Kotlin:

Create two extensions, one for EditText and one for TextView

EditText:

fun EditText.clear() { text.clear() }

TextView:

fun TextView.clear() { text = "" }

and use it like

myEditText.clear()

myTextView.clear()

If you want the file from a particular commit (any branch) , say 06f8251f

git checkout 06f8251f path_to_file

for example , in windows:

git checkout 06f8251f C:\A\B\C\D\file.h

You can also do it with JavaScript this way. It will find any iframe elements and remove their borders in IE and other browsers (though you can just set a style of "border : none;" in non-IE browsers instead of using JavaScript). AND it will work even if used AFTER the iframe is generated and in place in the document (e.g. iframes that are added in plain HTML and not JavaScript)!

This appears to work because IE creates the border, not on the iframe element as you'd expect, but on the CONTENT of the iframe--after the iframe is created in the BOM. ($@&*#@!!! IE!!!)

Note: The IE part will only work (of course) if the parent window and iframe are from the SAME origin (same domain, port, protocol etc.). Otherwise the script will get "access denied" errors in the IE error console. If that happens, your only option is to set it before it is generated, as others have noted, or use the non-standard frameBorder="0" attribute. (or just let IE look fugly--my current favorite option ;) )

Took me MANY hours of working to the point of despair to figure this out...

Enjoy. :)

// =========================================================================
// Remove borders on iFrames

if (window.document.getElementsByTagName("iframe"))
   {
      var iFrameElements = window.document.getElementsByTagName("iframe");
      for (var i = 0; i < iFrameElements.length; i++)
         {
            iFrameElements[i].frameBorder="0";   //  For other browsers.
            iFrameElements[i].setAttribute("frameBorder", "0");   //  For other browsers (just a backup for the above).
            iFrameElements[i].contentWindow.document.body.style.border="none";   //  For IE.
         }
   }

This works in SQL 2008 and 2012 to produce datetime2:

declare @date date = current_timestamp;
declare @time time = current_timestamp;

select 
@date as date
,@time as time
,cast(@date as datetime) + cast(@time as datetime) as datetime
,cast(@time as datetime2) as timeAsDateTime2
,dateadd(dayofyear,datepart(dayofyear,@date) - 1,dateadd(year,datepart(year,@date) - 1900,cast(@time as datetime2))) as datetime2;

Using jQuery button click

$('#button_id').on('click',function(){
     $('#form_id').submit();
 });

try:

pip install mysqlclient

I recommend to use it in a virtual environment.

In Gradle build file, add dependency:

implementation 'com.android.support:multidex:1.0.2'

or

implementation 'com.android.support:multidex:1.0.3'

or

implementation 'com.android.support:multidex:2.0.0'

And then in the "defaultConfig" section, add:

multiDexEnabled true

Under targetSdkVersion

minSdkVersion 17
targetSdkVersion 27
multiDexEnabled true

Now if you encounter this error

Error:Failed to resolve: multidex-instrumentation Open File

You need to change your gradle to 3.0.1

classpath 'com.android.tools.build:gradle:3.0.1'

And put the following code in the file gradle-wrapper.properties

distributionUrl=https://services.gradle.org/distributions/gradle-4.1-all.zip

Finally

add class Applition in project And introduce it to the AndroidManifest Which is extends from MultiDexApplication

public class App extends MultiDexApplication {

    @Override
    public void onCreate( ) {
        super.onCreate( );
    }
}

Run the project first to create an error, then clean the project

Finally, Re-launch the project and enjoy it

you can get the json string as a param of your ActionResult and afterwards serialize it using JSON.Net

HERE an example is being shown

in order to receive it in the serialized form as a param of the controller action you must either write a custom model binder or a Action filter (OnActionExecuting) so that the json string is serialized into the model of your liking and is available inside the controller body for use.

HERE is an implementation using the dynamic object

You could do it like this :

bool areFieldEmpty = YES;
//Label to leave the loops
outer_loop;

//For each input (except of submit) in your form
$('form input[type!=submit]').each(function(){
   //If the field's empty
   if($(this).val() != '')
   {
      //Mark it
      areFieldEmpty = NO;
      //Then leave all the loops
      break outer_loop;
   }
});

//Then test your bool 

just use -

if(!a) // if a is negative,undefined,null,empty value then...
{
    // do whatever
}
else {
    // do whatever
}

this works because of the == difference from === in javascript, which converts some values to "equal" values in other types to check for equality, as opposed for === which simply checks if the values equal. so basically the == operator know to convert the "", null, undefined to a false value. which is exactly what you need.

I've used a DOS command line to do this. Two lines, actually. The first one to make the "current directory" the folder where the file is - or the root folder of a group of folders where the file can be. The second line does the search.

CD C:\TheFolder
C:\TheFolder>FINDSTR /L /S /I /N /C:"TheString" *.PRG

You can find details about the parameters at this link.

Hope it helps!

Using the excellent answer from Max and This post about adding extra data files like images or sound & my own research/testing, I've figured out what I believe is the easiest way to add such files.

If you would like to see a live example, my repository is here on GitHub.

Note: this is for compiling using the --onefile or -F command with pyinstaller.

My environment is as follows.

• Python 3.3.7
• Tkinter 8.6 (check version)
• Pyinstaller 3.6

Solving the problem in 2 steps

To solve the issue we need to specifically tell Pyinstaller that we have extra files that need to be "bundled" with the application.

We also need to be using a 'relative' path, so the application can run properly when it's running as a Python Script or a Frozen EXE.

With that being said we need a function that allows us to have relative paths. Using the function that Max Posted we can easily solve the relative pathing.

def img_resource_path(relative_path):
    """ Get absolute path to resource, works for dev and for PyInstaller """
    try:
        # PyInstaller creates a temp folder and stores path in _MEIPASS
        base_path = sys._MEIPASS
    except Exception:
        base_path = os.path.abspath(".")

    return os.path.join(base_path, relative_path)

We would use the above function like this so the application icon shows up when the app is running as either a Script OR Frozen EXE.

icon_path = img_resource_path("app/img/app_icon.ico")
root.wm_iconbitmap(icon_path)

The next step is that we need to instruct Pyinstaller on where to find the extra files when it's compiling so that when the application is run, they get created in the temp directory.

We can solve this issue two ways as shown in the documentation, but I personally prefer managing my own .spec file so that's how we're going to do it.

First, you must already have a .spec file. In my case, I was able to create what I needed by running pyinstaller with extra args, you can find extra args here. Because of this, my spec file may look a little different than yours but I'm posting all of it for reference after I explain the important bits.

added_files is essentially a List containing Tuple's, in my case I'm only wanting to add a SINGLE image, but you can add multiple ico's, png's or jpg's using ('app/img/*.ico', 'app/img') You may also create another tuple like soadded_files = [ (), (), ()] to have multiple imports

The first part of the tuple defines what file or what type of file's you would like to add as well as where to find them. Think of this as CTRL+C

The second part of the tuple tells Pyinstaller, to make the path 'app/img/' and place the files in that directory RELATIVE to whatever temp directory gets created when you run the .exe. Think of this as CTRL+V

Under a = Analysis([main..., I've set datas=added_files, originally it used to be datas=[] but we want out the list of imports to be, well, imported so we pass in our custom imports.

You don't need to do this unless you want a specific icon for the EXE, at the bottom of the spec file I'm telling Pyinstaller to set my application icon for the exe with the option icon='app\\img\\app_icon.ico'.

added_files = [
    ('app/img/app_icon.ico','app/img/')
]
a = Analysis(['main.py'],
             pathex=['D:\\Github Repos\\Processes-Killer\\Process Killer'],
             binaries=[],
             datas=added_files,
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          [],
          name='Process Killer',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          upx_exclude=[],
          runtime_tmpdir=None,
          console=True , uac_admin=True, icon='app\\img\\app_icon.ico')

Compiling to EXE

I'm very lazy; I don't like typing things more than I have to. I've created a .bat file that I can just click. You don't have to do this, this code will run in a command prompt shell just fine without it.

Since the .spec file contains all of our compiling settings & args (aka options) we just have to give that .spec file to Pyinstaller.

pyinstaller.exe "Process Killer.spec"

I benchmarked the answers of Anthony Damico, Brian Diggs and data_steve on a small sample tbl_df and got the following results.

> data <- data.frame('a' = 1:3, 
+                    'b' = c('a','b','c'), 
+                    'c' = c('d', 'e', 'f'), 
+                    'd' = c('g', 'h', 'i'))
> data <- tbl_df(data)
> cols <- c("b", "c", "d")
> microbenchmark(

+     apply( data[ , cols ] , 1 , paste , collapse = "-" ),

However, when I evaluated on my own tbl_df with ~1 million rows and 10 columns the results were quite different.

put .gitignore in your main catalog

git status (you will see which files you can commit)
git add -A
git commit -m "message"
git push

Unfortunately, I think setInterval wins the prize:

<input type=text id=input_id />
<script>
setInterval(function() { ObserveInputValue($('#input_id').val()); }, 100);
</script>

It's the cleanest solution, at only 1 line of code. It's also the most robust, since you don't have to worry about all the different events/ways an input can get a value.

The downsides of using 'setInterval' don't seem to apply in this case:

• The 100ms latency? For many applications, 100ms is fast enough.
• Added load on the browser? In general, adding lots of heavy-weight setIntervals on your page is bad. But in this particular case, the added page load is undetectable.
• It doesn't scale to many inputs? Most pages don't have more than a handful of inputs, which you can sniff all in the same setInterval.

I've seen the same thing in firefox, css transform scaled transparent png's looking very rough.

I noticed that when they previously had a background color set the quality was much better, so I tried setting an RGBA background with as low an opacity value as possible.

background:rgba(255,255,255,0.001);

This worked for me, give it a try.

Please Try to pass parameters in httpoptions, you can follow function below

deleteAction(url, data) {
    const authToken = sessionStorage.getItem('authtoken');
    const options = {
      headers: new HttpHeaders({
        'Content-Type': 'application/json',
        Authorization: 'Bearer ' + authToken,
      }),
      body: data,
    };
    return this.client.delete(url, options);
  }

I Replaced PSLIST and PSEXEC with TASKKILL and TASKLIST`. As they seem to work better, I couldn't get PSLIST to run in Windows 7.

Also replaced Sleep with TIMEOUT.

This Was everything i needed to get the script running well, and all the additions was provided by the great guys who posted the comments.

Also if there is a delay before the .exe starts it might be worth inserting a Timeout before the :loop.

@ECHO OFF

TASKKILL NOTEPAD

START "" "C:\Program Files\Windows NT\Accessories\wordpad.exe"

:LOOP
tasklist | find /i "WORDPAD" >nul 2>&1
IF ERRORLEVEL 1 (
  GOTO CONTINUE
) ELSE (
  ECHO Wordpad is still running
  Timeout /T 5 /Nobreak
  GOTO LOOP
)

:CONTINUE

It's simple Use following pseudo code

from pylab import imread,subplot,imshow,show

import matplotlib.pyplot as plt

image = imread('...')  // choose image location

plt.imshow(image)

plt.show() // this will show you the image on console.

Let's understand in simple words

• PRI - It's a primary key, and used to identify records uniquely.
• UNI - It's a unique key, and also used to identify records uniquely. It looks similar like primary key but a table can have multiple unique keys and unique key can have one null value, on the other hand table can have only one primary key and can't store null as a primary key.
• MUL - It's doesn't have unique constraint and table can have multiple MUL columns.

Note: These keys have more depth as a concept but this is good to start.

is that what your looking for?

<table border="1">
<tr>
 <th scope="col">Header</th>
 <th scope="col">Header</th>
 <th scope="col" colspan="2">Header</th>
</tr>
<tr>
 <th scope="row">&nbsp;</th>
 <td>&nbsp;</td>
 <td>Split this one</td>
 <td>into two columns</td>
</tr>
</table>  

To use the hex encoding in Python 3, use

>>> import codecs
>>> codecs.encode(b"c", "hex")
b'63'

In legacy Python, there are several other ways of doing this:

>>> hex(ord("c"))
'0x63'
>>> format(ord("c"), "x")
'63'
>>> "c".encode("hex")
'63'

Though I consider myself a .NET developer, I don't prefer calling it that way. c# developer sounds much better and is a much clearer message: it says that I understand both C# and .NET (because C# and .NET are tied together). I could call myself a VB.NET developer, same story there.

What is a .NET developer? I don't know, because you cannot develop with .NET, if develop is a synonym for programming. .NET is the environment, the libraries, the languages, the CLR, the CLI, JIT, the LR, the BCL, the IDE and the IL. I find it a poor job description, but it may also mean that they don't really care: either you are an F#, a C#, an IronPython or a VB.NET developer, they're all implicitly and secretly .NET developers.

What do you need? A solid understanding why ".NET" is a poor job description and ask for a more precise one. Nobody can know everything of .NET, it is simply too wide. Orientate yourself to all sides of it and do both ASP.NET and WinForms. Don't forget Silverlight, WPF etc and two or three .NET languages.

In other words: know the forest by knowing what trees and flowers it habitats and specialize in knowing a few beautiful and common ones well.

In my case I forgot to add @RequestBody annotation to the method argument:

public TestController(@RequestBody KeeperClient testClient) {
        TestController.testClient = testClient;
    }

As said by JW, you can't find the current focused element, at least in a browser-independent way. But if your app is IE only (some are...), you can find it the following way :

document.activeElement

EDIT: It looks like IE did not have everything wrong after all, this is part of HTML5 draft and seems to be supported by the latest version of Chrome, Safari and Firefox at least.

Here is another quick approach without using additional panel.

JFrame f = new JFrame("stackoverflow") { 
  private Image backgroundImage = ImageIO.read(new File("background.jpg"));
  public void paint( Graphics g ) { 
    super.paint(g);
    g.drawImage(backgroundImage, 0, 0, null);
  }
};

Update: Unless you love resizing icons one by one, check out Schmoudi's answer. It's just a lot easier.

Icon sizes

Above image from Designing for iOS 9. They are the same for iOS 10.

How to Set the App Icon

Click Assets.xcassets in the Project navigator and then choose AppIcon.

This will give you an empty app icon set.

Now just drag the right sized image (in .png format) from Finder onto every blank in the app set. The app icon should be all set up now.

How to create the right sized images

The image at the very top tells the pixels sizes for for each point size that is required in iOS 9. However, even if I don't get this answer updated for future versions of iOS, you can still figure out the correct pixel sizes using the method below.

Look at how many points (pt) each blank on the empty image set is. If the image is 1x then the pixels are the same as the points. For 2x double the points and 3x triple the points. So, for example, in the first blank above (29pt 2x) you would need a 58x58 pixel image.

You can start with a 1024x1024 pixel image and then downsize it to the correct sizes. You can do it yourself or there are also websites and scripts for getting the right sizes. Do a search for "ios app icon generator" or something similar.

I don't think the names matter as long as you get the dimensions right, but the general naming convention is as follows:

Icon-29.png      // 29x29 pixels
[email protected]   // 58x58 pixels
[email protected]   // 87x87 pixels

Launch Image

Although you can use an image for the launch screen, consider using a launch screen storyboard file. This will conveniently resize for every size and orientation. Check out this SO answer or the following documentation for help with this.

Funnily enough the MySQL workbench solved it for me. In the Administration tab -> Users and Privileges, the user was listed with an error. Using the delete option solved the problem.

John Papa provided my issue on this rather obscure comment: Sometimes when you get that error, it means you are missing a file. Other times it means the module was defined after it was used. One way to solve this easily is to name the module files *.module.js and load those first.

Even if I want to return a business logic error as HTTP code there is no such acceptable HTTP error code for that errors rather than using HTTP 200 because it will misrepresent the actual error.

So, HTTP 200 will be good for business logic errors. But all errors which are covered by HTTP error codes should use them.

Basically HTTP 200 means what server correctly processes user request (in case of there is no seats on the plane it is no matter because user request was correctly processed, it can even return just a number of seats available on the plane, so there will be no business logic errors at all or that business logic can be on client side. Business logic error is an abstract meaning, but HTTP error is more definite).

IN your view insert

@Html.ValidationMessage("Error")

then in the controller after you use new in your model

var model = new yourmodel();
try{
[...]
}catch(Exception ex){
ModelState.AddModelError("Error", ex.Message);
return View(model);
}

Similar to tight_layout matplotlib now (as of version 2.2) provides constrained_layout. In contrast to tight_layout, which may be called any time in the code for a single optimized layout, constrained_layout is a property, which may be active and will optimze the layout before every drawing step.

Hence it needs to be activated before or during subplot creation, such as figure(constrained_layout=True) or subplots(constrained_layout=True).

Example:

import matplotlib.pyplot as plt

fig, axes = plt.subplots(4,4, constrained_layout=True)

plt.show()

constrained_layout may as well be set via rcParams

plt.rcParams['figure.constrained_layout.use'] = True

See the what's new entry and the Constrained Layout Guide

I had the exact same issue while working on a GIT based project. I was able to resolve by changing the way i was importing the project in the workspace.

Wrong way : Import project to workspace from GIT perspective , like right click on the GIT URL and selecting the option import which was not recognizing the project facets.

Right way (which resolved my issue): clone the project in GIT perspective , change to JEE Perspective , then import from file > import > Existing Maven Project .

There's the global attribute called hidden. But I'm green to all this and maybe there was a reason it wasn't mentioned yet?

var someCondition = true;_x000D_
_x000D_
if (someCondition == true){_x000D_
    document.getElementById('hidden div').hidden = false;_x000D_
}

<div id="hidden div" hidden>_x000D_
    stuff hidden by default_x000D_
</div>

According to the documentation NUM_ROWS is the "Number of rows in the table", so I can see how this might be confusing. There, however, is a major difference between these two methods.

This query selects the number of rows in MY_TABLE from a system view. This is data that Oracle has previously collected and stored.

select num_rows from all_tables where table_name = 'MY_TABLE'

This query counts the current number of rows in MY_TABLE

select count(*) from my_table

By definition they are difference pieces of data. There are two additional pieces of information you need about NUM_ROWS.

1. In the documentation there's an asterisk by the column name, which leads to this note:

   Columns marked with an asterisk (*) are populated only if you collect statistics on the table with the ANALYZE statement or the DBMS_STATS package.

   This means that unless you have gathered statistics on the table then this column will not have any data.

2. Statistics gathered in 11g+ with the default estimate_percent, or with a 100% estimate, will return an accurate number for that point in time. But statistics gathered before 11g, or with a custom estimate_percent less than 100%, uses dynamic sampling and may be incorrect. If you gather 99.999% a single row may be missed, which in turn means that the answer you get is incorrect.

If your table is never updated then it is certainly possible to use ALL_TABLES.NUM_ROWS to find out the number of rows in a table. However, and it's a big however, if any process inserts or deletes rows from your table it will be at best a good approximation and depending on whether your database gathers statistics automatically could be horribly wrong.

Generally speaking, it is always better to actually count the number of rows in the table rather then relying on the system tables.

From the man page, npm start:

runs a package's "start" script, if one was provided. If no version is specified, then it starts the "active" version.

Admittedly, that description is completely unhelpful, and that's all it says. At least it's more documented than socket.io.

Anyhow, what really happens is that npm looks in your package.json file, and if you have something like

"scripts": { "start": "coffee server.coffee" }

then it will do that. If npm can't find your start script, it defaults to:

node server.js

I think that this code is going to help:

JS:

$('#foo').ready(function () {
    $('#loadingMessage').css('display', 'none');
});
$('#foo').load(function () {
    $('#loadingMessage').css('display', 'none');
});

HTML:

<iframe src="http://google.com/" id="foo"></iframe>
<div id="loadingMessage">Loading...</div>

CSS:

#loadingMessage {
    width: 100%;
    height: 100%;
    z-index: 1000;
    background: #ccc;
    top: 0px;
    left: 0px;
    position: absolute;
}

Coverting epoch format to SimpleDateFormat in Android (Java / Kotlin)

input: 1613316655000

output: 2021-02-14T15:30:55.726Z

In Java

long milliseconds = 1613316655000L;
Date date = new Date(milliseconds);
String mobileDateTime = Utils.getFormatTimeWithTZ(date);

//method that returns SimpleDateFormat in String

public static String getFormatTimeWithTZ(Date currentTime) {
    SimpleDateFormat timeZoneDate = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.getDefault());
    return timeZoneString = timeZoneDate.format(currentTime);
}

In Kotlin

var milliseconds = 1613316655000L
var date = Date(milliseconds)
var mobileDateTime = Utils.getFormatTimeWithTZ(date)

//method that returns SimpleDateFormat in String

fun getFormatTimeWithTZ(currentTime:Date):String {
  val timeZoneDate = SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.getDefault())
  return timeZoneString = timeZoneDate.format(currentTime)
}

Pass the sheet name with the Range parameter of the DoCmd.TransferSpreadsheet Method. See the box titled "Worksheets in the Range Parameter" near the bottom of that page.

This code imports from a sheet named "temp" in a workbook named "temp.xls", and stores the data in a table named "tblFromExcel".

Dim strXls As String
strXls = CurrentProject.Path & Chr(92) & "temp.xls"
DoCmd.TransferSpreadsheet acImport, , "tblFromExcel", _
    strXls, True, "temp!"

What Anthony says is absolutely correct, but I'd like to add that your experience will likely show a lot better performance and efficiency (due not to fpm-vs-fcgi but more to the implementation of your httpd).

For example, I had a quad-core machine running lighttpd + fcgi humming along nicely. I upgraded to a 16-core machine to cope with growth, and two things exploded: RAM usage, and segfaults. I found myself restarting lighttpd every 30 minutes to keep the website up.

I switched to php-fpm and nginx, and RAM usage dropped from >20GB to 2GB. Segfaults disappeared as well. After doing some research, I learned that lighttpd and fcgi don't get along well on multi-core machines under load, and also have memory leak issues in certain instances.

Is this due to php-fpm being better than fcgi? Not entirely, but how you hook into php-fpm seems to be a whole heckuva lot more efficient than how you serve via fcgi.

The file may be existing but may have a different path. Try writing the absolute path for the file.

Try os.listdir() function to check that atleast python sees the file.

Try it like this:

file1 = open(r'Drive:\Dir\recentlyUpdated.yaml')

DateTime start1 = DateTime.Parse(txtDate.Text);

SELECT * 
FROM dbo.March2010 A
WHERE A.Date >= start1;

First convert TexBox into the Datetime then....use that variable into the Query
