I entirely agree that goto is poor poor coding, but no one has actually answered the question. There is in fact a goto module for Python (though it was released as an April fool joke and is not recommended to be used, it does work).

If it echoing out to a browser, you should use CSS. This would require also having the comment wrapped in an HTML tag. Something like:

echo '<p style="color: red; text-align: center">
      Request has been sent. Please wait for my reply!
      </p>';

I bumped with this issue a few days ago. I tried many solutions and none really worked for me on the end i ended up creating an extenion/override of the dropdown code of bootstrap. It is a copy of the original code with changes to the closeMenus function.

I think it is a good solution since it doesn't affects the core classes of bootstrap js.

You can check it out on gihub: https://github.com/djokodonev/bootstrap-multilevel-dropdown

Use this :

public View getViewByPosition(int pos, ListView listView) {
    final int firstListItemPosition = listView.getFirstVisiblePosition();
    final int lastListItemPosition = firstListItemPosition + listView.getChildCount() - 1;

    if (pos < firstListItemPosition || pos > lastListItemPosition ) {
        return listView.getAdapter().getView(pos, null, listView);
    } else {
        final int childIndex = pos - firstListItemPosition;
        return listView.getChildAt(childIndex);
    }
}

I ran into a similar issue. I solved it by setting the Executable options in a variable and then simply calling the variable. Below is a sample setup.py that I use:

from cx_Freeze import setup, Executable
import sys

productName = "ProductName"
if 'bdist_msi' in sys.argv:
    sys.argv += ['--initial-target-dir', 'C:\InstallDir\\' + productName]
    sys.argv += ['--install-script', 'install.py']

exe = Executable(
      script="main.py",
      base="Win32GUI",
      targetName="Product.exe"
     )
setup(
      name="Product.exe",
      version="1.0",
      author="Me",
      description="Copyright 2012",
      executables=[exe],
      scripts=[
               'install.py'
               ]
      ) 

Just give the following command with your command prompt.

git update-git-for-windows

This will ask you a confirmation as follows. Press Y to proceed.

Once the files are dowloaded, Continue with normal installation procedures. You can check the git version after finishing installation with the following command

git version

For me, the result was as follows.

I think this will work for you. But visitors are easy if they got something in seconds without spending more time and hence they will also again visit your site. <a href="file.zip" onclick="if (event.button==0) setTimeout(function(){document.body.innerHTML='thanks!'},500)"> Start automatic download! </a>

Either create a directory under /app/src/main or use studio File-> New -> Folder - > Assets Folder.

Assuming you don't want to create another class, you can always let the deserializer give you a dictionary of key-value-pairs, like so:

string s = //{ "user" : {    "id" : 12345,    "screen_name" : "twitpicuser"}};
var serializer = new JavaScriptSerializer();
var result = serializer.DeserializeObject(s);

You'll get back something, where you can do:

var userId = int.Parse(result["user"]["id"]); // or (int)result["user"]["id"] depending on how the JSON is serialized.
// etc.

Look at result in the debugger to see, what's in there.

AFAIK there is no way to visually see line endings in the editor space, but in the bottom-right corner of the window there is an indicator that says "CLRF" or "LF" which will let you set the line endings for a particular file. Clicking on the text will allow you to change the line endings as well.

Perhaps table is what you are after?

dummyData = rep(c(1,2, 2, 2), 25)

table(dummyData)
# dummyData
#  1  2 
# 25 75

## or another presentation of the same data
as.data.frame(table(dummyData))
#    dummyData Freq
#  1         1   25
#  2         2   75

I had a very messy cody that loaded facebook's javascript via AJAX and i had to make sure that the js file has been completely loaded before calling FB.init this seem to work for me

    $jQuery.load( document.location.protocol + '//connect.facebook.net/en_US/all.js',
      function (obj) {
        FB.init({
           appId  : 'YOUR APP ID',
           status : true, // check login status
           cookie : true, // enable cookies to allow the server to access the session
           xfbml  : true  // parse XFBML
        });
        //ANy other FB.related javascript here
      });

This code uses jquery to load the javascript and do the function callback onLoad of the javascript. it's a lot less messier than having creating an onLoad eventlistener for the block which in the end didn't work very well on IE6, 7 and 8

Here is what I ended up doing to work around the error.

First, I set up the database recovery model as SIMPLE. More information here.

Then, by deleting some old files I was able to make 5GB of free space which gave the log file more space to grow.

I reran the DELETE statement sucessfully without any warning.

I thought that by running the DELETE statement the database would inmediately become smaller thus freeing space in my hard drive. But that was not true. The space freed after a DELETE statement is not returned to the operating system inmediatedly unless you run the following command:

DBCC SHRINKDATABASE (MyDb, 0);
GO

More information about that command here.

If you did want something that behaved more like a static constant value in modern browsers (in that it can't be changed by other code), you could add a get only accessor to the Library class (this will only work for ES5+ browsers and NodeJS):

export class Library {
    public static get BOOK_SHELF_NONE():string { return "None"; }
    public static get BOOK_SHELF_FULL():string { return "Full"; }   
}

var x = Library.BOOK_SHELF_NONE;
console.log(x);
Library.BOOK_SHELF_NONE = "Not Full";
x = Library.BOOK_SHELF_NONE;
console.log(x);

If you run it, you'll see how the attempt to set the BOOK_SHELF_NONE property to a new value doesn't work.

2.0

In TypeScript 2.0, you can use readonly to achieve very similar results:

export class Library {
    public static readonly BOOK_SHELF_NONE = "None";
    public static readonly BOOK_SHELF_FULL = "Full";
}

The syntax is a bit simpler and more obvious. However, the compiler prevents changes rather than the run time (unlike in the first example, where the change would not be allowed at all as demonstrated).

You should define the path on which the cookie exists to ensure that you are deleting the correct cookie.

function set_cookie(name, value) {
  document.cookie = name +'='+ value +'; Path=/;';
}
function delete_cookie(name) {
  document.cookie = name +'=; Path=/; Expires=Thu, 01 Jan 1970 00:00:01 GMT;';
}

If you don't specify the path, the browser will set a cookie relative to the page you are currently on, so if you delete the cookie while on a different page, the other cookie continues its existence.

Edit based on @Evan Morrison's comment.
Be aware that in some cases to identify the correct cookie, the Domain parameter is required.
Usually it's defined as Domain=.yourdomain.com.
Placing a dot in front of your domain name means that this cookie may exist on any sub-domain (www also counts as sub-domain).

Also, as mentioned in @RobertT's answer, HttpOnly cookies cannot be deleted with JavaScript on the client side.

1. Summary

Answer for 2019: you can still use protocol-relative URLs, but this technique an anti-pattern.

Also:

1. You may have problems in developing.
2. Some third-party tools may not support them.

Migrating from protocol-relative URLs to https:// it would be nice.

2. Relevance

This answer is relevant for January 2019. In the future, the data of this answer may be obsolete.

3. Anti-pattern

3.1. Argumentation

Paul Irish — front-end engineer and a developer advocate for the Google Chrome — write in 2014, December:

Now that SSL is encouraged for everyone and doesn’t have performance concerns, this technique is now an anti-pattern. If the asset you need is available on SSL, then always use the https:// asset.

Allowing the snippet to request over HTTP opens the door for attacks like the recent GitHub Man-on-the-side attack. It’s always safe to request HTTPS assets even if your site is on HTTP, however the reverse is not true.

3.2. Another links

• Loads page resources using protocol relative URIs
• Stop using protocol-relative URLs

3.3. Examples

• In 2017 Stack Overflow switched from protocol-relative URLs to https
• In 2018 Chrome will flag all unencrypted websites as “not secure”

4. Developing process

For example, I try to use clean-console.

• Example file KiraCleanConsole__cdn_links_demo.html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>clean-console without protocol demonstration</title>
    <!-- Really dead link -->
    <script src="https://unpkg.com/bowser@latest/bowser.min.js"></script>
    <!-- Package exists; link without “https:” -->

    <script src="https://cdn.jsdelivr.net/npm/gemini-scrollbar/index.js"></script>
</head>

Link //cdn.jsdelivr.net/npm/[email protected]/dist/jquery.min.js is valid, but I getting an error.

Pay attention to file://cdn.jsdelivr.net/npm/[email protected]/dist/jquery.min.js and read Thilo and bg17aw answers about file://.

I didn't know about this behavior and couldn't understand why I have problems like this for pageres.

5. Third-party tools

I use Clickable URLs Sublime Text package. Use it, I can simply open links from my text editor in browser.

Both links in example are valid. But first link I can successfully open in browser use Clickable URLs, second link — no. This may not be very convenient.

6. Conclusion

Yes:

1. If you have problems as in Developing process item, you can set your development workflow.
2. Else you have problems as in Third-party tools item, you can contribute tools.

But you don't need this additional problems. Read information by links in Anti-pattern item: protocol-relative URLs is obsolete.

SSL development libraries have to be installed

CentOS:

$ yum install openssl-devel libffi-devel

Ubuntu:

$ apt-get install libssl-dev libffi-dev

OS X (with Homebrew installed):

$ brew install openssl

Thanks a lot Codo.

This fixed my issue when I restarted the mysql service. Just run:

brew services start mysql

you can also use just like this in newer version of sql,

select year('2001-02-16 20:38:40') as year,
month('2001-02-16 20:38:40') as month,
day('2001-02-16 20:38:40') as day,
hour('2001-02-16 20:38:40') as hour,
minute('2001-02-16 20:38:40') as minute

Try find . -type d or find . -type d -ls

You will need to have some access to the Form's Instance to access its Controls collection and thereby changing the Text Box's Text.

One of ways could be that You can have a Your Form's Instance Available as Public or More better Create a new Constructor For your Second Form and have it receive the Form1's instance during initialization.

These helped me a lot: I wanted to save values from my gridview, and it was reloading my gridview /overriding my new values, as i have IsPostBack inside my PageLoad.

if (HttpContext.Current.Request["MYCLICKEDBUTTONID"] == null)
{
   //Do not reload the gridview.

}
else
{
   reload my gridview.

Mixing positional and flag-based arguments

--param=arg (equals delimited)

Freely mixing flags between positional arguments:

./script.sh dumbo 127.0.0.1 --environment=production -q -d
./script.sh dumbo --environment=production 127.0.0.1 --quiet -d

can be accomplished with a fairly concise approach:

# process flags
pointer=1
while [[ $pointer -le $# ]]; do
   param=${!pointer}
   if [[ $param != "-"* ]]; then ((pointer++)) # not a parameter flag so advance pointer
   else
      case $param in
         # paramter-flags with arguments
         -e=*|--environment=*) environment="${param#*=}";;
                  --another=*) another="${param#*=}";;

         # binary flags
         -q|--quiet) quiet=true;;
                 -d) debug=true;;
      esac

      # splice out pointer frame from positional list
      [[ $pointer -gt 1 ]] \
         && set -- ${@:1:((pointer - 1))} ${@:((pointer + 1)):$#} \
         || set -- ${@:((pointer + 1)):$#};
   fi
done

# positional remain
node_name=$1
ip_address=$2

--param arg (space delimited)

It's usualy clearer to not mix --flag=value and --flag value styles.

./script.sh dumbo 127.0.0.1 --environment production -q -d

This is a little dicey to read, but is still valid

./script.sh dumbo --environment production 127.0.0.1 --quiet -d

I think you are wrapping your exception in another exception (which isn't in your code above). If you try out this code:

public static void main(String[] args) {
    try {
        throw new RuntimeException("Cannot move file");
    } catch (Exception ex) {
        JOptionPane.showMessageDialog(null, "Error: " + ex.getMessage());
    }
}

...you will see a popup that says exactly what you want.

However, to solve your problem (the wrapped exception) you need get to the "root" exception with the "correct" message. To do this you need to create a own recursive method getRootCause:

public static void main(String[] args) {
    try {
        throw new Exception(new RuntimeException("Cannot move file"));
    } catch (Exception ex) {
        JOptionPane.showMessageDialog(null,
                                      "Error: " + getRootCause(ex).getMessage());
    }
}

public static Throwable getRootCause(Throwable throwable) {
    if (throwable.getCause() != null)
        return getRootCause(throwable.getCause());

    return throwable;
}

Note: Unwrapping exceptions like this however, sort of breaks the abstractions. I encourage you to find out why the exception is wrapped and ask yourself if it makes sense.

Something not mentioned here, although a bit similar to the second alternative of the accepted answer but different and low cost for big hierarchy query and easy (insert update delete) items, would be adding a persistent path column for each item.

some like:

id | name        | path
19 | category1   | /19
20 | category2   | /19/20
21 | category3   | /19/20/21
22 | category4   | /19/20/21/22

Example:

-- get children of category3:
SELECT * FROM my_table WHERE path LIKE '/19/20/21%'
-- Reparent an item:
UPDATE my_table SET path = REPLACE(path, '/19/20', '/15/16') WHERE path LIKE '/19/20/%'

Optimise the path length and ORDER BY path using base36 encoding instead real numeric path id

 // base10 => base36
 '1' => '1',
 '10' => 'A',
 '100' => '2S',
 '1000' => 'RS',
 '10000' => '7PS',
 '100000' => '255S',
 '1000000' => 'LFLS',
 '1000000000' => 'GJDGXS',
 '1000000000000' => 'CRE66I9S'

https://en.wikipedia.org/wiki/Base36

Suppressing also the slash '/' separator by using fixed length and padding to the encoded id

Detailed optimization explanation here: https://bojanz.wordpress.com/2014/04/25/storing-hierarchical-data-materialized-path/

You are probably going to need to use the STATUS_ON_ICC_READ constant and maybe put what you get there into your apps local db so that you can keep track of what you have already read vs the new stuff for your app to parse through. BUT bear in mind that you have to declare the use of the class in your manifest, so users will see that you have access to their SMS called out in the permissions dialogue they get when they install. Seeing SMS access is unusual and could put some users off. Good luck.

Here is the link that goes into depth on the Sms Manager

This may be overkill for what you require, but I found this library to be very helpful:

http://fittextjs.com/

It's only good for single lines though, so I'm not certain if that fits your requirement.

After two dozens of comments to understand the situation, it was found that the libhdf5.so.7 was actually a symlink (with several levels of indirection) to a file that was not shared between the queued processes and the interactive processes. This means even though the symlink itself lies on a shared filesystem, the contents of the file do not and as a result the process was seeing different versions of the library.

For future reference: other than checking LD_LIBRARY_PATH, it's always a good idea to check a library with nm -D to see if the symbols actually exist. In this case it was found that they do exist in interactive mode but not when run in the queue. A quick md5sum revealed that the files were actually different.

A character is anything that you can type such as letters,digits,punctuations and spaces. Strings appears in variables.i.e they are text items in perls. A character consist of 16bits. While the lenght of a string is unlimited.

The fundamental difference in most programming languages is that unless the unexpected happens a for loop will always repeat n times or until a break statement, (which may be conditional), is met then finish with a while loop it may repeat 0 times, 1, more or even forever, depending on a given condition which must be true at the start of each loop for it to execute and always false on exiting the loop, (for completeness a do ... while loop, (or repeat until), for languages that have it, always executes at least once and does not guarantee the condition on the first execution).

It is worth noting that in Python a for or while statement can have break, continue and else statements where:

• break - terminates the loop
• continue - moves on to the next time around the loop without executing following code this time around
• else - is executed if the loop completed without any break statements being executed.

N.B. In the now unsupported Python 2 range produced a list of integers but you could use xrange to use an iterator. In Python 3 range returns an iterator.

So the answer to your question is 'it all depends on what you are trying to do'!

Most of the answers are outdated now. Better if you import tqdm correctly.

from tqdm import tqdm_notebook as tqdm

May or may not be accurate, but according to this site: http://www.htmlite.com/mysql003.php.

BLOB A string with a maximum length of 65535 characters.

The MySQL manual says:

The maximum size of a BLOB or TEXT object is determined by its type, but the largest value you actually can transmit between the client and server is determined by the amount of available memory and the size of the communications buffers

I think the first site gets their answers from interpreting the MySQL manual, per http://dev.mysql.com/doc/refman/5.0/en/storage-requirements.html

If you have access to your apache install and trust third-party code, you can use the apache upload progress module (if you use apache; there's also a nginx upload progress module).

Otherwise, you'd have to write a script that you can hit out of band to request the status of the file (checking the filesize of the tmp file for instance).

There's some work going on in firefox 3 I believe to add upload progress support to the browser, but that's not going to get into all the browsers and be widely adopted for a while (more's the pity).

This provides a named variable to work with:

foreach my $line ( <STDIN> ) {
    chomp( $line );
    print "$line\n";
}

To read a file, pipe it in like this:

program.pl < inputfile

The answer above is now obsolete with Unity 5 or newer. Use this instead!

GetComponent<Rigidbody2D>().AddForce(new Vector2(0,10), ForceMode2D.Impulse);

I also want to add that this leaves the jump height super private and only editable in the script, so this is what I did...

    public float playerSpeed;  //allows us to be able to change speed in Unity
public Vector2 jumpHeight;

// Use this for initialization
void Start () {

}
// Update is called once per frame
void Update ()
{
    transform.Translate(playerSpeed * Time.deltaTime, 0f, 0f);  //makes player run

    if (Input.GetMouseButtonDown(0) || Input.GetKeyDown(KeyCode.Space))  //makes player jump
    {
        GetComponent<Rigidbody2D>().AddForce(jumpHeight, ForceMode2D.Impulse);

This makes it to where you can edit the jump height in Unity itself without having to go back to the script.

Side note - I wanted to comment on the answer above, but I can't because I'm new here. :)

As you can see, 01/01/1970 returns 0, which means it is the lowest possible date.

new Date('1970-01-01Z00:00:00:000') //returns Thu Jan 01 1970 01:00:00 GMT+0100 (Central European Standard Time)
new Date('1970-01-01Z00:00:00:000').getTime() //returns 0
new Date('1970-01-01Z00:00:00:001').getTime() //returns 1

To Milan Babuškov, IMO, this is exactly what the replacement function should look like :-)

FILE _iob[] = {*stdin, *stdout, *stderr};

extern "C" FILE * __cdecl __iob_func(void)
{
    return _iob;
}

I think the simplest way to achieve your goal is this:

var str   = 'asd-0.testing';
var regex = /(asd-)(\d)(\.\w+)/;
var anyNumber = 1;
var res = str.replace(regex, `$1${anyNumber}$3`);

John Resig posted a good implementation:

// Array Remove - By John Resig (MIT Licensed)
Array.prototype.remove = function(from, to) {
  var rest = this.slice((to || from) + 1 || this.length);
  this.length = from < 0 ? this.length + from : from;
  return this.push.apply(this, rest);
};

If you don’t want to extend a global object, you can do something like the following, instead:

// Array Remove - By John Resig (MIT Licensed)
Array.remove = function(array, from, to) {
    var rest = array.slice((to || from) + 1 || array.length);
    array.length = from < 0 ? array.length + from : from;
    return array.push.apply(array, rest);
};

But the main reason I am posting this is to warn users against the alternative implementation suggested in the comments on that page (Dec 14, 2007):

Array.prototype.remove = function(from, to){
  this.splice(from, (to=[0,from||1,++to-from][arguments.length])<0?this.length+to:to);
  return this.length;
};

It seems to work well at first, but through a painful process I discovered it fails when trying to remove the second to last element in an array. For example, if you have a 10-element array and you try to remove the 9th element with this:

myArray.remove(8);

You end up with an 8-element array. Don't know why but I confirmed John's original implementation doesn't have this problem.

To show NumberPicker in AlertDialog use this code :

final AlertDialog.Builder d = new AlertDialog.Builder(context);
LayoutInflater inflater = this.getLayoutInflater();
View dialogView = inflater.inflate(R.layout.number_picker_dialog, null);
d.setTitle("Title");
d.setMessage("Message");
d.setView(dialogView);
final NumberPicker numberPicker = (NumberPicker) dialogView.findViewById(R.id.dialog_number_picker);
numberPicker.setMaxValue(50);
numberPicker.setMinValue(1);
numberPicker.setWrapSelectorWheel(false);
numberPicker.setOnValueChangedListener(new NumberPicker.OnValueChangeListener() {
    @Override
    public void onValueChange(NumberPicker numberPicker, int i, int i1) {
        Log.d(TAG, "onValueChange: ");
    }
});
d.setPositiveButton("Done", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialogInterface, int i) {
        Log.d(TAG, "onClick: " + numberPicker.getValue());
    }
});
d.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialogInterface, int i) {
    }
});
AlertDialog alertDialog = d.create();
alertDialog.show();

You can use like 'A%' expression, but if you want this query to run fast for large tables I'd recommend you to put number of first button into separate field with tiny int type.

Try

gadget_url.value=''

addGadgetUrl.addEventListener('click', () => {_x000D_
   gadget_url.value = '';_x000D_
});

<div>_x000D_
  <p>URL</p>_x000D_
  <input type="text" name="gadget_url" id="gadget_url" style="width: 350px;" class="input" value="some value" />_x000D_
  <input type="button" id="addGadgetUrl" value="add gadget" />_x000D_
  <br>_x000D_
  <span id="error"></span>_x000D_
</div>

Update

I don't know why so many downovotes (and no comments) - however (for future readers) don't think that this solution not work - It works with html provided in OP question and this is SHORTEST working solution - you can try it by yourself HERE

For VB.Net

CType(GridControl1.MainView, GridView).GetFocusedRow()

For C#

((GridView)gridControl1.MainView).GetFocusedRow();

example bind data by linq so use

Dim selRow As CUSTOMER = CType(GridControl1.MainView, GridView).GetFocusedRow()

I know that the question is too old, anyway:

select a, b from mytable group by a, b

will give your all the combinations.

use button array like this.it will create 3 dynamic buttons bcoz h variable has value of 3

private void button1_Click(object sender, EventArgs e)
{
int h =3;


Button[] buttonArray = new Button[8];

for (int i = 0; i <= h-1; i++)
{
   buttonArray[i] = new Button();
   buttonArray[i].Size = new Size(20, 43);
   buttonArray[i].Name= ""+i+"";
   buttonArray[i].Click += button_Click;//function
   buttonArray[i].Location = new Point(40, 20 + (i * 20));
    panel1.Controls.Add(buttonArray[i]);

}  }

FXCop typically prefers OrdinalIgnoreCase. But your requirements may vary.

For English there is very little difference. It is when you wander into languages that have different written language constructs that this becomes an issue. I am not experienced enough to give you more than that.

OrdinalIgnoreCase

The StringComparer returned by the OrdinalIgnoreCase property treats the characters in the strings to compare as if they were converted to uppercase using the conventions of the invariant culture, and then performs a simple byte comparison that is independent of language. This is most appropriate when comparing strings that are generated programmatically or when comparing case-insensitive resources such as paths and filenames. http://msdn.microsoft.com/en-us/library/system.stringcomparer.ordinalignorecase.aspx

InvariantCultureIgnoreCase

The StringComparer returned by the InvariantCultureIgnoreCase property compares strings in a linguistically relevant manner that ignores case, but it is not suitable for display in any particular culture. Its major application is to order strings in a way that will be identical across cultures. http://msdn.microsoft.com/en-us/library/system.stringcomparer.invariantcultureignorecase.aspx

The invariant culture is the CultureInfo object returned by the InvariantCulture property.

The InvariantCultureIgnoreCase property actually returns an instance of an anonymous class derived from the StringComparer class.

It depends on how you're going to work and who your provider is.

If you work with a sms-gateway company you'll probably work through SMPP protocol (3.4 is still the most common), then have a look on OpenSMPP and jSMPP. These are powerful libs to work with SMPP.

If you're going to work with your own hardware (f.e. a gsm-modem) the easiest way to send messages is through AT commands, they differ depends on the model, so, you should find out what AT commands is supported by your modem. Next, if your modem has an IP and open to connection, you can send commands through java socket

Socket smppSocket = new Socket("YOUR_MODEM_IP", YOUR_MODEM_PORT);
DataOutputStream os = new DataOutputStream(smppSocket.getOutputStream());
DataInputStream is = new DataInputStream(smppSocket.getInputStream());

os.write(some_byte_array[]);
is.readLine();

Otherwise you'll work through a COM port, but the method is the same (sending AT commands), you can find more information how to work with serial ports here.

In JavaScript strings can be either string primitive type or string objects. The following code shows the distinction:

var a: string = 'test'; // string literal
var b: String = new String('another test'); // string wrapper object

console.log(typeof a); // string
console.log(typeof b); // object

Your error:

Type 'String' is not assignable to type 'string'. 'string' is a primitive, but 'String' is a wrapper object. Prefer using 'string' when possible.

Is thrown by the TS compiler because you tried to assign the type string to a string object type (created via new keyword). The compiler is telling you that you should use the type string only for strings primitive types and you can't use this type to describe string object types.

The finite repetition syntax uses {m,n} in place of star/plus/question mark.

From java.util.regex.Pattern:

X{n}      X, exactly n times
X{n,}     X, at least n times
X{n,m}    X, at least n but not more than m times

All repetition metacharacter have the same precedence, so just like you may need grouping for *, +, and ?, you may also for {n,m}.

• ha* matches e.g. "haaaaaaaa"
• ha{3} matches only "haaa"
• (ha)* matches e.g. "hahahahaha"
• (ha){3} matches only "hahaha"

Also, just like *, +, and ?, you can add the ? and + reluctant and possessive repetition modifiers respectively.

    System.out.println(
        "xxxxx".replaceAll("x{2,3}", "[x]")
    ); "[x][x]"

    System.out.println(
        "xxxxx".replaceAll("x{2,3}?", "[x]")
    ); "[x][x]x"

Essentially anywhere a * is a repetition metacharacter for "zero-or-more", you can use {...} repetition construct. Note that it's not true the other way around: you can use finite repetition in a lookbehind, but you can't use * because Java doesn't officially support infinite-length lookbehind.

This indicates the linux has delivered a SIGTERM to your process. This is usually at the request of some other process (via kill()) but could also be sent by your process to itself (using raise()). This signal requests an orderly shutdown of your process.

If you need a quick cheatsheet of signal numbers, open a bash shell and:

$ kill -l

You can determine the sender by using an appropriate signal handler like:

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

void sigterm_handler(int signal, siginfo_t *info, void *_unused)
{
  fprintf(stderr, "Received SIGTERM from process with pid = %u\n",
      info->si_pid);
  exit(0);
}

int main (void)
{
  struct sigaction action = {
    .sa_handler = NULL,
    .sa_sigaction = sigterm_handler,
    .sa_mask = 0,
    .sa_flags = SA_SIGINFO,
    .sa_restorer = NULL
  };

  sigaction(SIGTERM, &action, NULL);
  sleep(60);

  return 0;
}

Notice that the signal handler also includes a call to exit(). It's also possible for your program to continue to execute by ignoring the signal, but this isn't recommended in general (if it's a user doing it there's a good chance it will be followed by a SIGKILL if your process doesn't exit, and you lost your opportunity to do any cleanup then).

First you download ODBC driver psqlodbc_09_01_0200-x64.zip then you installed it.After that go to START->Program->Administrative tools then you select Data Source ODBC then you double click on the same after that you select PostgreSQL 30 then you select configure then you provide proper details such as db name user Id host name password of the same database in this way you will configured your DSN connection.After That you will check SSL should be allow .

Then you go on next tab system DSN then you select ADD tabthen select postgreSQL_ANSI_64X ODBC after you that you have created PostgreSQL ODBC connection.

• @PathVariable is to obtain some placeholder from the URI (Spring call it an URI Template) — see Spring Reference Chapter 16.3.2.2 URI Template Patterns
• @RequestParam is to obtain a parameter from the URI as well — see Spring Reference Chapter 16.3.3.3 Binding request parameters to method parameters with @RequestParam

If the URL http://localhost:8080/MyApp/user/1234/invoices?date=12-05-2013 gets the invoices for user 1234 on December 5th, 2013, the controller method would look like:

@RequestMapping(value="/user/{userId}/invoices", method = RequestMethod.GET)
public List<Invoice> listUsersInvoices(
            @PathVariable("userId") int user,
            @RequestParam(value = "date", required = false) Date dateOrNull) {
  ...
}

Also, request parameters can be optional, and as of Spring 4.3.3 path variables can be optional as well. Beware though, this might change the URL path hierarchy and introduce request mapping conflicts. For example, would /user/invoices provide the invoices for user null or details about a user with ID "invoices"?

NOTE: Hopefully this changed in the latest version.

You cannot copy data between a MongoDB 4.0 mongod instance (regardless of the FCV value) and a MongoDB 3.4 and earlier mongod instance. https://docs.mongodb.com/v4.0/reference/method/db.copyDatabase/

ALERT: Hey folks just be careful while copying the database, if you don't want to mess up the different collections under single database.

The following shows you how to rename

> show dbs;
testing
games
movies

To rename you use the following syntax

db.copyDatabase("old db name","new db name")

Example:

db.copyDatabase('testing','newTesting')

Now you can safely delete the old db by the following way

use testing;

db.dropDatabase(); //Here the db **testing** is deleted successfully

Now just think what happens if you try renaming the new database name with existing database name

Example:

db.copyDatabase('testing','movies'); 

So in this context all the collections (tables) of testing will be copied to movies database.

To bypass google's check, which is what you really want, simply remove the extensions from the file when you send it, and add them back after you download it. For example:

• tar czvf file.tar.gz directory
• mv file.tar.gz filetargz
• [send filetargz via gmail]
• [download filetargz]
• [rename filetargz to file.tar.gz and open]

first, get the container id of the desired container by

docker ps

you will get something like this:

CONTAINER ID        IMAGE                  COMMAND             CREATED             STATUS                          PORTS                    NAMES
3ac548b6b315        frontend_react-web     "npm run start"     48 seconds ago      Up 47 seconds                   0.0.0.0:3000->3000/tcp   frontend_react-web_1

now copy this container id and run the following command:

docker exec -it container_id sh

docker exec -it 3ac548b6b315 sh

I had today the same problem, but only when working with a stored procedure. This make the query behave like a multi query, so you need to "consume" other results available before make another query.

while($this->mysql->more_results()){
    $this->mysql->next_result();
    $this->mysql->use_result();
}

If you want to add a dynamic class to your host element, you may combine your HostBinding with a getter as

@HostBinding('class') get class() {
    return aComponentVariable
}

Comparator provides a way for you to provide custom comparison logic for types that you have no control over.

Comparable allows you to specify how objects that you are implementing get compared.

Obviously, if you don't have control over a class (or you want to provide multiple ways to compare objects that you do have control over) then use Comparator.

Otherwise you can use Comparable.

1. Ctrl-D would delete a line
2. Ctrl-Z would undo deletion, with highlithing entire line
3. Ctrl-X/C cut or copy entire line

The advantage over Ctrl-Alt-Down followed by Ctrl-X suggested by other users is that it doesn't make eclipse think that the file was changed in any way. It's also faster and causes no problems even if the user has rotating screen issue with Ctrl-Alt-Down/Up keyboard shorcut. So there's no need to remap shorcuts for this.

Another way to go would be hitting Alt-Shift-Up until the entire line gets selected. If you've gone too far, of course you can select less with Alt-Shift-Down.

Normally jQuery selectors do not search within the "text nodes" in the DOM. However if you use the .contents() function, text nodes will be included, then you can use the nodeType property to filter only the text nodes, and the nodeValue property to search the text string.

    $('*', 'body')
        .andSelf()
        .contents()
        .filter(function(){
            return this.nodeType === 3;
        })
        .filter(function(){
            // Only match when contains 'simple string' anywhere in the text
            return this.nodeValue.indexOf('simple string') != -1;
        })
        .each(function(){
            // Do something with this.nodeValue
        });

I assume you would need the value as string. You could use the code below. It will always return give you the two digit minutes as string.

var date = new Date(date);
var min = date.getMinutes();

if (min < 10) {
min = '0' + min;
} else {
min = min + '';
}
console.log(min);

Hope this helps.

For me I was getting the problem when deploying a geoserver WAR into tomcat 7

To fix it, I was on Java 7 and upgrading to Java 8.

This is running under a docker container. Tomcat 7.0.75 + Java 8 + Geos 2.10.2

I had the same problem when I'm using spring-context version 4.0.6 and spring-security version 4.1.0.

When changing spring-security version to 4.0.4 (because 4.0.6 of spring-security not available) in my pom and security xml-->schemaLocation, it gets compiled without internet.

So that mean you can also solve this by:

• changing spring-security to a older or same version than spring-context.

• changing spring-context to a newer or same version than spring-security.

(any way spring-context to be newer or same version to spring-security)

Should it be necessary to manually remove a service:

1. Run Regedit or regedt32.
2. Find the registry key entry for your service under the following key: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services
3. Delete the Registry Key

You will have to reboot before the list gets updated in services

this seems simpler, but only works on Oracle:

ALTER TABLE [Table] 
ALTER [Column] NUMBER DEFAULT 0 NOT NULL;

in addition, with this, you can also add columns, not just alter it. It updates to the default value (0) in this example, if the value was null.

#include<stdio.h>
#include <sys/types.h>
#include <unistd.h>

int main()
{
    // Create a child process     
    int pid = fork();

    if (pid > 0)
    {

            int j=getpid();

            printf("in parent process %d\n",j);
    }
    // Note that pid is 0 in child process
    // and negative if fork() fails
    else if (pid == 0)
    {





            int i=getppid();
            printf("Before sleep %d\n",i);

            sleep(5);
            int k=getppid();

            printf("in child process %d\n",k);
    }

    return 0;

}

There is another option to scroll page to required element if element has "id" attribute

If you want to navigate to page and scroll down to element with @id, it can be done automatically by adding #element_id to URL...

Example

Let's say we need to navigate to Selenium Waits documentation and scroll page down to "Implicit Wait" section. We can do

driver.get('https://selenium-python.readthedocs.io/waits.html')

and add code for scrolling...OR use

driver.get('https://selenium-python.readthedocs.io/waits.html#implicit-waits')

to navigate to page AND scroll page automatically to element with id="implicit-waits" (<div class="section" id="implicit-waits">...</div>)

I tried:

<input id="btnTest" type="button" value="button" />

<script type="text/javascript">
    $(document).ready( function() {
      $('#btnTest').click( function() {
        $.ajax({
          type: "POST", 
          url: "/Login/Test",
          data: { ListID: '1', ItemName: 'test' },
          dataType: "json",
          success: function(response) { alert(response); },
          error: function(xhr, ajaxOptions, thrownError) { alert(xhr.responseText); }
        });
      });
    });
</script>

and C#:

[HttpPost]
public ActionResult Test(string ListID, string ItemName)
{
    return Content(ListID + " " + ItemName);
}

It worked. Remove contentType and set data without double quotes.

If by "given enough time" you mean 100 years and you're creating them at a rate of a billion a second, then yes, you have a 50% chance of having a collision after 100 years.

Use this code to check the internet connection

ConnectivityManager connectivityManager = (ConnectivityManager) ctx
                .getSystemService(Context.CONNECTIVITY_SERVICE);
        if ((connectivityManager
                .getNetworkInfo(ConnectivityManager.TYPE_MOBILE) != null && connectivityManager
                .getNetworkInfo(ConnectivityManager.TYPE_MOBILE).getState() == NetworkInfo.State.CONNECTED)
                || (connectivityManager
                        .getNetworkInfo(ConnectivityManager.TYPE_WIFI) != null && connectivityManager
                        .getNetworkInfo(ConnectivityManager.TYPE_WIFI)
                        .getState() == NetworkInfo.State.CONNECTED)) {
            return true;
        } else {
            return false;
        }

var SendInfo= { SendInfo: [... your elements ...]};

        $.ajax({
            type: 'post',
            url: 'Your-URI',
            data: JSON.stringify(SendInfo),
            contentType: "application/json; charset=utf-8",
            traditional: true,
            success: function (data) {
                ...
            }
        });

and in action

public ActionResult AddDomain(IEnumerable<PersonSheets> SendInfo){
...

you can bind your array like this

var SendInfo = [];

$(this).parents('table').find('input:checked').each(function () {
    var domain = {
        name: $("#id-manuf-name").val(),
        address: $("#id-manuf-address").val(),
        phone: $("#id-manuf-phone").val(),
    }

    SendInfo.push(domain);
});

hope this can help you.

Now you can do it like so (you do not need to go to github or open new directory from git):

If stuffs is a list of strings, just this would work:

{{ stuffs|join(", ") }}

p.s.

More reader friendly way {{ my ~ ', ' ~ string }}

Here's technique I figured out after a bit of trial and error that allows you to preserve your XML styles and avoid the issues of using a <merge/> (i.e. inflate() requires a merge to attach to root, and returns the root node). No runtime new TableRow()s or new TextView()s required.

Code

Note: Here CheckBalanceActivity is some sample Activity class

TableLayout table = (TableLayout)CheckBalanceActivity.this.findViewById(R.id.attrib_table);
for(ResourceBalance b : xmlDoc.balance_info)
{
    // Inflate your row "template" and fill out the fields.
    TableRow row = (TableRow)LayoutInflater.from(CheckBalanceActivity.this).inflate(R.layout.attrib_row, null);
    ((TextView)row.findViewById(R.id.attrib_name)).setText(b.NAME);
    ((TextView)row.findViewById(R.id.attrib_value)).setText(b.VALUE);
    table.addView(row);
}
table.requestLayout();     // Not sure if this is needed.

attrib_row.xml

<?xml version="1.0" encoding="utf-8"?>
<TableRow style="@style/PlanAttribute"  xmlns:android="http://schemas.android.com/apk/res/android">
    <TextView
        style="@style/PlanAttributeText"
        android:id="@+id/attrib_name"
        android:textStyle="bold"/>
    <TextView
        style="@style/PlanAttributeText"
        android:id="@+id/attrib_value"
        android:gravity="right"
        android:textStyle="normal"/>
</TableRow>

php curl lib is just a wrapper of cUrl, so, first of all, you should install cUrl. Download the cUrl source to your linux server. Then, use the follow commands to install:

tar zxvf cUrl_src_taz
cd cUrl_src_taz
./configure --prefix=/curl/install/home
make
make test    (optional)
make install
ln -s  /curl/install/home/bin/curl-config /usr/bin/curl-config

Then, copy the head files in the "/curl/install/home/include/" to "/usr/local/include". After all above steps done, the php curl extension configuration could find the original curl, and you can use the standard php extension method to install php curl.
Hope it helps you, :)

The best solution would be to use the so-called Element Queries. However, they are not standard, no specification exists - and the only option is to use one of the polyfills/libraries available, if you want to go this way.

The idea behind element queries is to allow a certain container on the page to respond to the space that's provided to it. This will allow to write a component once and then drop it anywhere on the page, while it will adjust its contents to its current size. No matter what the Window size is. This is the first difference that we see between element queries and media queries. Everyone hopes that at some point a specification will be created that will standardize element queries (or something that achieves the same goal) and make them native, clean, simple and robust. Most people agree that Media queries are quite limited and don't help for modular design and true responsiveness.

There are a few polyfills/libraries that solve the problem in different ways (could be called workarounds instead of solutions though):

• CSS Element Queries - https://github.com/marcj/css-element-queries
• BoomQueries - https://github.com/BoomTownROI/boomqueries
• eq.js - https://github.com/Snugug/eq.js
• ElementQuery - https://github.com/tysonmatanich/elementQuery
• And a few more, which I'm not going to list here, but you're free to search. I would not be able to say which of the currently available options is the best. You'll have to try a few and decide.

I have seen other solutions to similar problems proposed. Usually they use timers or the Window/viewport size under the hood, which is not a real solution. Furthermore, I think ideally this should be solved mainly in CSS, and not in javascript or html.

If the question is docker related... the official nginx docker images do this by making softlinks towards stdout/stderr

RUN ln -sf /dev/stdout /var/log/nginx/access.log && ln -sf /dev/stderr /var/log/nginx/error.log

The same as an int:

float f = 6;

Also here's how to programmatically convert from an int to a float, and a single in C# is the same as a float:

int i = 8;
float f = Convert.ToSingle(i);

Or you can just cast an int to a float:

float f = (float)i;

There are two primary contenders for python apps on Android

Chaquopy

https://chaquo.com/chaquopy/

This integrates with the Android build system, it provides a Python API for all android features. To quote the site "The complete Android API and user interface toolkit are directly at your disposal."

Beeware (Toga widget toolkit)

https://pybee.org/

This provides a multi target transpiler, supports many targets such as Android and iOS. It uses a generic widget toolkit (toga) that maps to the host interface calls.

Which One?

Both are active projects and their github accounts shows a fair amount of recent activity.

Beeware Toga like all widget libraries is good for getting the basics out to multiple platforms. If you have basic designs, and a desire to expand to other platforms this should work out well for you.

On the other hand, Chaquopy is a much more precise in its mapping of the python API to Android. It also allows you to mix in Java, useful if you want to use existing code from other resources. If you have strict design targets, and predominantly want to target Android this is a much better resource.

The answer by Larry Hastings has some great general advice about sockets, but there are a couple of mistakes as it pertains to how the recv(bufsize) method works in the Python socket module.

So, to clarify, since this may be confusing to others looking to this for help:

1. The bufsize param for the recv(bufsize) method is not optional. You'll get an error if you call recv() (without the param).
2. The bufferlen in recv(bufsize) is a maximum size. The recv will happily return fewer bytes if there are fewer available.

See the documentation for details.

Now, if you're receiving data from a client and want to know when you've received all of the data, you're probably going to have to add it to your protocol -- as Larry suggests. See this recipe for strategies for determining end of message.

As that recipe points out, for some protocols, the client will simply disconnect when it's done sending data. In those cases, your while True loop should work fine. If the client does not disconnect, you'll need to figure out some way to signal your content length, delimit your messages, or implement a timeout.

I'd be happy to try to help further if you could post your exact client code and a description of your test protocol.

From official doc :

fromHtml(String) method was deprecated in API level 24. use fromHtml(String, int) instead.

1. TO_HTML_PARAGRAPH_LINES_CONSECUTIVE Option for toHtml(Spanned, int): Wrap consecutive lines of text delimited by '\n' inside <p> elements.

2. TO_HTML_PARAGRAPH_LINES_INDIVIDUAL Option for toHtml(Spanned, int): Wrap each line of text delimited by '\n' inside a <p> or a <li> element.

Try this code to 100% work....

UIImageView * imageview = [[UIImageView alloc] initWithFrame:CGRectMake(20,100, 80, 80)];
imageview.image = [UIImage imageNamed:@"myimage.jpg"];
[self.view  addSubview:imageview];

Just rain into the same problem -- and here's how I addressed it.

Assuming mysqld is running, then the problem might just be the mysql client not knowing where to look for the socket file.

The most straightforward way to address this consists in adding the following line to your user's profile .my.cnf file (on linux that's usually under /home/myusername):

socket=<path to the mysql socket file>

If you don't have a .my.cnf file there, then create one containing the following:

[mysql]
socket=<path to the mysql socket file>

In my case, since I moved the mysql default data folder (/var/lib/mysql) in a different location (/data/mysql), I added to .my.cnf the following:

[mysql]
socket=/data/mysql/mysql.sock

Hope this helps.

You can use resize like this:

For n = 1 To 5
    Columns(n).Resize(, 5).Select
    '~~> rest of your code
Next

In any Range Manipulation that you do, always keep at the back of your mind Resize and Offset property.

The class you apply on the div can be used to as a reference point to style elements with that div, for example.

<div class="area1">
    <table>
        <tr>
                <td class="item">Text Text Text</td>
                <td class="item">Text Text Text</td>
        </tr>
    </table>
</div>


.area1 { border:1px solid black; }

.area1 td { color:red; } /* This will effect any TD within .area1 */

To be super semantic you should move the class onto the table.

    <table class="area1">
        <tr>
                <td>Text Text Text</td>
                <td>Text Text Text</td>
        </tr>
    </table>

The problem is that codeAddress() doesn't have enough scope to be callable from the button. You must declare it outside the callback to ready():

function codeAddress() {
    var address = document.getElementById("formatedAddress").value;
    geocoder.geocode( { 'address': address}, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            map.setCenter(results[0].geometry.location);
        }
    });
}


$(document).ready(function(){
    // Do stuff here, including _calling_ codeAddress(), but not _defining_ it!
});

What worked for me :

div#scrollable {
    overflow-y: scroll;
    max-height: 100vh;
}

In my memory, excel (versions >= 2007) limits the power 2 of 20: 1.048.576 lines.

Csv is over to this boundary, like ordinary text file. So you will be care of the transfer between two formats.

People tend to over complicate things by giving the definition which says:

flatMap transform the items emitted by an Observable into Observables, then flatten the emissions from those into a single Observable

I swear this definition still confuses me but I am going to explain it in the simplest way which is by using an example

Our Situation: we have an observable which returns data(simple URL) that we are going to use to make an HTTP call that will return an observable containing the data we need so you can visualize the situation like this:

Observable 1
    |_
       Make Http Call Using Observable 1 Data (returns Observable_2)
            |_
               The Data We Need

so as you can see we can't reach the data we need directly so the first way to retrieve the data we can use just normal subscriptions like this:

Observable_1.subscribe((URL) => {
         Http.get(URL).subscribe((Data_We_Need) => {
                  console.log(Data_We_Need);
          });
});

this works but as you can see we have to nest subscriptions to get our data this currently does not look bad but imagine we have 10 nested subscriptions that would become unmaintainable.

so a better way to handle this is just to use the operator flatMap which will do the same thing but makes us avoid that nested subscription:

Observable_1
    .flatMap(URL => Http.get(URL))
    .subscribe(Data_We_Need => console.log(Data_We_Need));

I was facing the same issue, I made below changes and the issue got resolved.

Open watchQueryOptions.d.ts file

\apollo-client\core\watchQueryOptions.d.ts

Change the query type any instead of DocumentNode, Same for mutation

Before:

export interface QueryBaseOptions<TVariables = OperationVariables> {
    query: **DocumentNode**;

After:

export interface QueryBaseOptions<TVariables = OperationVariables> {
    query: **any**;

One more use of .ascx files is, they can be used for Partial Page caching in ASP.NET pages. What we have to do is to create an ascx file and then move the controls or portion of the page we need to cache into that control. Then add the @OutputCache directive in the ascx control and it will be cached separately from the parent page. It is used when you don't want to cache the whole page but only a specific portion of the page.

You can use triple quotes (single ' or double "):

a = """
text
text
text
"""

print(a)

My version:

div#dashmain { margin-left:150px; }
div#dashside {position:fixed; width:150px; height:100%; }

<div id="dashside"></div>
<div id="dashmain">                        
    <div class="container-fluid">
        <div class="row">
            <div class="col-md-12">Content</div>
        </div>            
    </div>        
</div>

You can do it faster without any imports just by using magics:

%env CUDA_DEVICE_ORDER=PCI_BUS_ID
%env CUDA_VISIBLE_DEVICES=0

Notice that all env variable are strings, so no need to use ". You can verify that env-variable is set up by running: %env <name_of_var>. Or check all of them with %env.

Declare your menu field.

private Menu menu;

Following is onCreateOptionsMenu() method

public boolean onCreateOptionsMenu(Menu menu) {
this.menu = menu;
    try {
        getMenuInflater().inflate(R.menu.menu_main,menu);
    } catch (Exception e) {
        e.printStackTrace();
        Log.i(TAG, "onCreateOptionsMenu: error: "+e.getMessage());
    }
    return super.onCreateOptionsMenu(menu);
}

Following will be your name setter activity. Either through a button click or through conditional code

public void setMenuName(){
menu.findItem(R.id.menuItemId).setTitle(/*Set your desired menu title here*/);
}

This worked for me.

You need an additional library for code coverage, and you are going to be blown away by how powerful and easy istanbul is. Try the following, after you get your mocha tests to pass:

npm install nyc

Now, simply place the command nyc in front of your existing test command, for example:

{
  "scripts": {
    "test": "nyc mocha"
  }
}

You may have select option values such as "Choose option". If you want to keep that value and clear the rest of the values you can first remove all the values and append "Choose Option"

<select multiple='multiple' id='selectName'> 
    <option selected disabled>Choose Option</option>
    <option>1</option> 
    <option>2</option> 
    <option>3</option>    
</select>

Jquery

$('#selectName option').remove(); // clear all values 
$('#selectName ').append('<option selected disabled>Choose Option</option>'); //append what you want to keep

Short version

element.setAttribute("required", "");    //turns required on
element.required = true;                 //turns required on through reflected attribute
jQuery(element).attr('required', '');    //turns required on
$("#elementId").attr('required', '');    //turns required on

element.removeAttribute("required");     //turns required off
element.required = false;                //turns required off through reflected attribute
jQuery(element).removeAttr('required');  //turns required off
$("#elementId").removeAttr('required');  //turns required off

if (edName.hasAttribute("required")) { }  //check if required
if (edName.required) { }                 //check if required using reflected attribute

Long Version

Once T.J. Crowder managed to point out reflected properties, i learned that following syntax is wrong:

element.attributes["name"] = value; //bad! Overwrites the HtmlAttribute object
element.attributes.name = value;    //bad! Overwrites the HtmlAttribute object
value = element.attributes.name;    //bad! Returns the HtmlAttribute object, not its value
value = element.attributes["name"]; //bad! Returns the HtmlAttribute object, not its value

You must go through element.getAttribute and element.setAttribute:

element.getAttribute("foo");         //correct
element.setAttribute("foo", "test"); //correct

This is because the attribute actually contains a special HtmlAttribute object:

element.attributes["foo"];           //returns HtmlAttribute object, not the value of the attribute
element.attributes.foo;              //returns HtmlAttribute object, not the value of the attribute

By setting an attribute value to "true", you are mistakenly setting it to a String object, rather than the HtmlAttribute object it requires:

element.attributes["foo"] = "true";  //error because "true" is not a HtmlAttribute object
element.setAttribute("foo", "true"); //error because "true" is not an HtmlAttribute object

Conceptually the correct idea (expressed in a typed language), is:

HtmlAttribute attribute = new HtmlAttribute();
attribute.value = "";
element.attributes["required"] = attribute;

This is why:

• getAttribute(name)
• setAttribute(name, value)

exist. They do the work on assigning the value to the HtmlAttribute object inside.

On top of this, some attribute are reflected. This means that you can access them more nicely from Javascript:

//Set the required attribute
//element.setAttribute("required", ""); 
element.required = true;

//Check the attribute
//if (element.getAttribute("required")) {...}
if (element.required) {...}

//Remove the required attribute
//element.removeAttribute("required");
element.required = false;

What you don't want to do is mistakenly use the .attributes collection:

element.attributes.required = true;     //WRONG!
if (element.attributes.required) {...}  //WRONG!
element.attributes.required = false;    //WRONG!

Testing Cases

This led to testing around the use of a required attribute, comparing the values returned through the attribute, and the reflected property

document.getElementById("name").required;
document.getElementById("name").getAttribute("required");

with results:

HTML                         .required        .getAttribute("required")
==========================   ===============  =========================
<input>                      false (Boolean)  null (Object)
<input required>             true  (Boolean)  "" (String)
<input required="">          true  (Boolean)  "" (String)
<input required="required">  true  (Boolean)  "required" (String)
<input required="true">      true  (Boolean)  "true" (String)
<input required="false">     true  (Boolean)  "false" (String)
<input required="0">         true  (Boolean)  "0" (String)

Trying to access the .attributes collection directly is wrong. It returns the object that represents the DOM attribute:

edName.attributes["required"] => [object Attr]
edName.attributes.required    => [object Attr]

This explains why you should never talk to the .attributes collect directly. You're not manipulating the values of the attributes, but the objects that represent the attributes themselves.

How to set required?

What's the correct way to set required on an attribute? You have two choices, either the reflected property, or through correctly setting the attribute:

element.setAttribute("required", "");         //Correct
edName.required = true;                       //Correct

Strictly speaking, any other value will "set" the attribute. But the definition of Boolean attributes dictate that it should only be set to the empty string "" to indicate true. The following methods all work to set the required Boolean attribute,

but do not use them:

element.setAttribute("required", "required"); //valid, but not preferred
element.setAttribute("required", "foo");      //works, but silly
element.setAttribute("required", "true");     //Works, but don't do it, because:
element.setAttribute("required", "false");    //also sets required boolean to true
element.setAttribute("required", false);      //also sets required boolean to true
element.setAttribute("required", 0);          //also sets required boolean to true

We already learned that trying to set the attribute directly is wrong:

edName.attributes["required"] = true;       //wrong
edName.attributes["required"] = "";         //wrong
edName.attributes["required"] = "required"; //wrong
edName.attributes.required = true;          //wrong
edName.attributes.required = "";            //wrong
edName.attributes.required = "required";    //wrong

How to clear required?

The trick when trying to remove the required attribute is that it's easy to accidentally turn it on:

edName.removeAttribute("required");     //Correct
edName.required = false;                //Correct

With the invalid ways:

edName.setAttribute("required", null);    //WRONG! Actually turns required on!
edName.setAttribute("required", "");      //WRONG! Actually turns required on!
edName.setAttribute("required", "false"); //WRONG! Actually turns required on!
edName.setAttribute("required", false);   //WRONG! Actually turns required on!
edName.setAttribute("required", 0);       //WRONG! Actually turns required on!

When using the reflected .required property, you can also use any "falsey" values to turn it off, and truthy values to turn it on. But just stick to true and false for clarity.

How to check for required?

Check for the presence of the attribute through the .hasAttribute("required") method:

if (edName.hasAttribute("required"))
{
}

You can also check it through the Boolean reflected .required property:

if (edName.required)
{
}

As of 2.6, set.intersection takes arbitrarily many iterables.

>>> s1 = set([1, 2, 3])
>>> s2 = set([2, 3, 4])
>>> s3 = set([2, 4, 6])
>>> s1 & s2 & s3
set([2])
>>> s1.intersection(s2, s3)
set([2])
>>> sets = [s1, s2, s3]
>>> set.intersection(*sets)
set([2])

Put this code wherever you want to insert a new line:

bufferedWriter.newLine();

If you don't want to use DI or Factories. You can refactor your class in a little tricky way:

public class Foo {
    private Bar bar;

    public void foo(Bar bar){
        this.bar = (bar != null) ? bar : new Bar();
        bar.someMethod();
        this.bar = null;  // for simulating local scope
    }
}

And your test class:

@RunWith(MockitoJUnitRunner.class)
public class FooTest {
    @Mock Bar barMock;
    Foo foo;

    @Test
    public void testFoo() {
       foo = new Foo();
       foo.foo(barMock);
       verify(barMock, times(1)).someMethod();
    }
}

Then the class that is calling your foo method will do it like this:

public class thirdClass {

   public void someOtherMethod() {
      Foo myFoo = new Foo();
      myFoo.foo(null);
   }
}

As you can see when calling the method this way, you don't need to import the Bar class in any other class that is calling your foo method which is maybe something you want.

Of course the downside is that you are allowing the caller to set the Bar Object.

Hope it helps.

I would say use an RDBMS if you need complex transactions. Otherwise I would go with MongoDB - more flexible to work with and you know it can scale when you need to. (I'm biased though - I work on the MongoDB project)

To loop from current record to the end:

While Me.CurrentRecord < Me.Recordset.RecordCount
    ' ... do something to current record
    ' ...

    DoCmd.GoToRecord Record:=acNext
Wend

To check if it is possible to go to next record:

If Me.CurrentRecord < Me.Recordset.RecordCount Then
    ' ...
End If

performance wise, my (crude) measurements found no difference on 1000 writes and reads

security wise, intuitively it would seem the localStore might be shut down before the sessionStore, but have no concrete evidence - maybe someone else does?

functional wise, concur with digitalFresh above

I would extend this question with a NDIS driver example on getting time. As one knows, KeQuerySystemTime (mimicked under NdisGetCurrentSystemTime) has a low resolution above milliseconds, and there are some processes like network packets or other IRPs which may need a better timestamp;

The example is just as simple:

LONG_INTEGER data, frequency;
LONGLONG diff;
data = KeQueryPerformanceCounter((LARGE_INTEGER *)&frequency)
diff = data.QuadPart / (Frequency.QuadPart/$divisor)

where divisor is 10^3, or 10^6 depending on required resolution.

I had a similar problem where I needed to only show a value from another Excel cell if the font was black. I created this function: `Option Explicit

Function blackFont(r As Range) As Boolean If r.Font.Color = 0 Then blackFont = True Else blackFont = False End If

End Function `

In my cell I have this formula: =IF(blackFont(Y51),Y51," ")

This worked well for me to test for a black font and only show the value in the Y51 cell if it had a black font.

The method you're using to read the http body response returns a byte slice:

To check for assignability, you can use the Type.IsAssignableFrom method:

typeof(SomeType).IsAssignableFrom(typeof(Derived))

This will work as you expect for type-equality, inheritance-relationships and interface-implementations but not when you are looking for 'assignability' across explicit / implicit conversion operators.

To check for strict inheritance, you can use Type.IsSubclassOf:

typeof(Derived).IsSubclassOf(typeof(SomeType))

Tips of using OS-dependent function to terminate C++ thread:

1. std::thread::native_handle() only can get the thread’s valid native handle type before calling join() or detach(). After that, native_handle() returns 0 - pthread_cancel() will coredump.

2. To effectively call native thread termination function(e.g. pthread_cancel()), you need to save the native handle before calling std::thread::join() or std::thread::detach(). So that your native terminator always has a valid native handle to use.

I converted the script to Python3 and ran it on my Raspberry Pi 3B+:

import time
import threading

def t():
        with open('/dev/urandom', 'rb') as f:
                for x in range(100):
                        f.read(4 * 65535)

if __name__ == '__main__':
    start_time = time.time()
    t()
    t()
    t()
    t()
    print("Sequential run time: %.2f seconds" % (time.time() - start_time))

    start_time = time.time()
    t1 = threading.Thread(target=t)
    t2 = threading.Thread(target=t)
    t3 = threading.Thread(target=t)
    t4 = threading.Thread(target=t)
    t1.start()
    t2.start()
    t3.start()
    t4.start()
    t1.join()
    t2.join()
    t3.join()
    t4.join()
    print("Parallel run time: %.2f seconds" % (time.time() - start_time))

python3 t.py

Sequential run time: 2.10 seconds
Parallel run time: 1.41 seconds

For me, running parallel was quicker.

Looks like the image is too big and the window simply doesn't fit the screen. Create window with the cv2.WINDOW_NORMAL flag, it will make it scalable. Then you can resize it to fit your screen like this:

from __future__ import division
import cv2


img = cv2.imread('1.jpg')

screen_res = 1280, 720
scale_width = screen_res[0] / img.shape[1]
scale_height = screen_res[1] / img.shape[0]
scale = min(scale_width, scale_height)
window_width = int(img.shape[1] * scale)
window_height = int(img.shape[0] * scale)

cv2.namedWindow('dst_rt', cv2.WINDOW_NORMAL)
cv2.resizeWindow('dst_rt', window_width, window_height)

cv2.imshow('dst_rt', img)
cv2.waitKey(0)
cv2.destroyAllWindows()

According to the OpenCV documentation CV_WINDOW_KEEPRATIO flag should do the same, yet it doesn't and it's value not even presented in the python module.

I asked in #machomebrew and learned that you can switch between versions using brew switch.

$ brew switch libfoo mycopy 

to get version mycopy of libfoo.

This is a classpath issue when running an executable jar as follows:

java -jar myfile.jar

One way to fix the problem is to set the classpath on the java command line as follows, adding the missing log4j jar:

java -cp myfile.jar:log4j.jar:otherjar.jar com.abc.xyz.MyMainClass

Of course the best solution is to add the classpath into the jar manifest so that the we can use the "-jar" java option:

<jar jarfile="myfile.jar">
    ..
    ..
    <manifest>
       <attribute name="Main-Class" value="com.abc.xyz.MyMainClass"/>
       <attribute name="Class-Path" value="log4j.jar otherjar.jar"/>
    </manifest>
</jar>

The following answer demonstrates how you can use the manifestclasspath to automate the seeting of the classpath manifest entry

Cannot find Main Class in File Compiled With Ant

This is because findViewById() searches in the activity_main layout, while the button is located in the fragment's layout fragment_main.

Move that piece of code in the onCreateView() method of the fragment:

//...

View rootView = inflater.inflate(R.layout.fragment_main, container, false);
Button buttonClick = (Button)rootView.findViewById(R.id.button);
buttonClick.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        onButtonClick((Button) view);
    }
});

Notice that now you access it through rootView view:

Button buttonClick = (Button)rootView.findViewById(R.id.button);

otherwise you would get again NullPointerException.

If you are developing on Netbeans, you will not get the Third-Party add-ons. You can download the Skins directly from Samsung here: http://developer.samsung.com/android/tools-sdks

After download, unzip to ...\Android\android-sdk\add-ons[name of device]

Restart the Android SDK Manager, and the new device should be there under Extras.

It would be better to add the download site directly to the SDK...if anyone knows it, please post it.

I think this is what you want:

/grand/parent/child[@id="#grand"]

I recognize that the answer works and has been accepted but there is a much cleaner way to write that query. Tested on mysql and postgres.

SELECT wpoi.order_id As No_Commande
FROM  wp_woocommerce_order_items AS wpoi
LEFT JOIN wp_postmeta AS wpp ON wpoi.order_id = wpp.post_id 
                            AND wpp.meta_key = '_shipping_first_name'
WHERE  wpoi.order_id =2198 

Also, this worked very well for me:

<textarea class="form-control" rows="3" name="msg" placeholder="Your message here." onfocus='this.select()'>
<?php if (isset($_POST['encode'])) { echo htmlspecialchars($_POST['msg']);} ?>
</textarea>

In this case, $_POST['encode'] came from this:

<input class="input_bottom btn btn-default" type="submit" name="encode" value="Encode">

The PHP code was inserted between the and tags.

Important Note: As of mid-2018, the process to get twitter API tokens became a lot more bureaucratic. It has taken me over one working week to be provided a set of API tokens, and this is for an open source project for you guys and girls with over 1.2 million installations on Packagist and 1.6k stars on Github, which theoretically should be higher priority.

If you are tasked with working with the twitter API for your work, you must take this potentially extremely long wait-time into account. Also consider other social media avenues like Facebook or Instagram and provide these options, as the process for retrieving their tokens is instant.

So you want to use the Twitter v1.1 API?

Note: the files for these are on GitHub.

Version 1.0 will soon be deprecated and unauthorised requests won't be allowed. So, here's a post to help you do just that, along with a PHP class to make your life easier.

1. Create a developer account: Set yourself up a developer account on Twitter

You need to visit the official Twitter developer site and register for a developer account. This is a free and necessary step to make requests for the v1.1 API.

2. Create an application: Create an application on the Twitter developer site

What? You thought you could make unauthenticated requests? Not with Twitter's v1.1 API. You need to visit http://dev.twitter.com/apps and click the "Create Application" button.

On this page, fill in whatever details you want. For me, it didn't matter, because I just wanted to make a load of block requests to get rid of spam followers. The point is you are going to get yourself a set of unique keys to use for your application.

So, the point of creating an application is to give yourself (and Twitter) a set of keys. These are:

• The consumer key
• The consumer secret
• The access token
• The access token secret

There's a little bit of information here on what these tokens for.

3. Create access tokens: You'll need these to make successful requests

OAuth requests a few tokens. So you need to have them generated for you.

Click "create my access token" at the bottom. Then once you scroll to the bottom again, you'll have some newly generated keys. You need to grab the four previously labelled keys from this page for your API calls, so make a note of them somewhere.

4. Change access level: You don't want read-only, do you?

If you want to make any decent use of this API, you'll need to change your settings to Read & Write if you're doing anything other than standard data retrieval using GET requests.

Choose the "Settings" tab near the top of the page.

Give your application read / write access, and hit "Update" at the bottom.

You can read more about the applications permission model that Twitter uses here.

5. Write code to access the API: I've done most of it for you

I combined the code above, with some modifications and changes, into a PHP class so it's really simple to make the requests you require.

This uses OAuth and the Twitter v1.1 API, and the class I've created which you can find below.

require_once('TwitterAPIExchange.php');

/** Set access tokens here - see: https://dev.twitter.com/apps/ **/
$settings = array(
    'oauth_access_token' => "YOUR_OAUTH_ACCESS_TOKEN",
    'oauth_access_token_secret' => "YOUR_OAUTH_ACCESS_TOKEN_SECRET",
    'consumer_key' => "YOUR_CONSUMER_KEY",
    'consumer_secret' => "YOUR_CONSUMER_SECRET"
);

Make sure you put the keys you got from your application above in their respective spaces.

Next you need to choose a URL you want to make a request to. Twitter has their API documentation to help you choose which URL and also the request type (POST or GET).

/** URL for REST request, see: https://dev.twitter.com/docs/api/1.1/ **/
$url = 'https://api.twitter.com/1.1/blocks/create.json';
$requestMethod = 'POST';

In the documentation, each URL states what you can pass to it. If we're using the "blocks" URL like the one above, I can pass the following POST parameters:

/** POST fields required by the URL above. See relevant docs as above **/
$postfields = array(
    'screen_name' => 'usernameToBlock', 
    'skip_status' => '1'
);

Now that you've set up what you want to do with the API, it's time to make the actual request.

/** Perform the request and echo the response **/
$twitter = new TwitterAPIExchange($settings);
echo $twitter->buildOauth($url, $requestMethod)
             ->setPostfields($postfields)
             ->performRequest();

And for a POST request, that's it!

For a GET request, it's a little different. Here's an example:

/** Note: Set the GET field BEFORE calling buildOauth(); **/
$url = 'https://api.twitter.com/1.1/followers/ids.json';
$getfield = '?username=J7mbo';
$requestMethod = 'GET';
$twitter = new TwitterAPIExchange($settings);
echo $twitter->setGetfield($getfield)
             ->buildOauth($url, $requestMethod)
             ->performRequest();     

Final code example: For a simple GET request for a list of my followers.

$url = 'https://api.twitter.com/1.1/followers/list.json';
$getfield = '?username=J7mbo&skip_status=1';
$requestMethod = 'GET';
$twitter = new TwitterAPIExchange($settings);
echo $twitter->setGetfield($getfield)
             ->buildOauth($url, $requestMethod)
             ->performRequest();  

I've put these files on GitHub with credit to @lackovic10 and @rivers! I hope someone finds it useful; I know I did (I used it for bulk blocking in a loop).

Also, for those on Windows who are having problems with SSL certificates, look at this post. This library uses cURL under the hood so you need to make sure you have your cURL certs set up probably. Google is also your friend.

We've been working on a similar issue at work today, trying to figure out how to make a dropdown div disappear when it is clicked off of. Ours is slightly different than the initial poster's question because we didn't want to click away from a different component or directive, but merely outside of the particular div.

We ended up solving it by using the (window:mouseup) event handler.

Steps:
1.) We gave the entire dropdown menu div a unique class name.

2.) On the inner dropdown menu itself (the only portion that we wanted clicks to NOT close the menu), we added a (window:mouseup) event handler and passed in the $event.

NOTE: It could not be done with a typical "click" handler because this conflicted with the parent click handler.

3.) In our controller, we created the method that we wanted to be called on the click out event, and we use the event.closest (docs here) to find out if the clicked spot is within our targeted-class div.

 autoCloseForDropdownCars(event) {_x000D_
        var target = event.target;_x000D_
        if (!target.closest(".DropdownCars")) { _x000D_
            // do whatever you want here_x000D_
        }_x000D_
    }

 <div class="DropdownCars">_x000D_
   <span (click)="toggleDropdown(dropdownTypes.Cars)" class="searchBarPlaceholder">Cars</span>_x000D_
   <div class="criteriaDropdown" (window:mouseup)="autoCloseForDropdownCars($event)" *ngIf="isDropdownShown(dropdownTypes.Cars)">_x000D_
   </div>_x000D_
</div>

Reading and writing binary files is pretty much the same as any other file, the only difference is how you open it:

unsigned char buffer[10];
FILE *ptr;

ptr = fopen("test.bin","rb");  // r for read, b for binary

fread(buffer,sizeof(buffer),1,ptr); // read 10 bytes to our buffer

You said you can read it, but it's not outputting correctly... keep in mind that when you "output" this data, you're not reading ASCII, so it's not like printing a string to the screen:

for(int i = 0; i<10; i++)
    printf("%u ", buffer[i]); // prints a series of bytes

Writing to a file is pretty much the same, with the exception that you're using fwrite() instead of fread():

FILE *write_ptr;

write_ptr = fopen("test.bin","wb");  // w for write, b for binary

fwrite(buffer,sizeof(buffer),1,write_ptr); // write 10 bytes from our buffer

Since we're talking Linux.. there's an easy way to do a sanity check. Install hexdump on your system (if it's not already on there) and dump your file:

mike@mike-VirtualBox:~/C$ hexdump test.bin
0000000 457f 464c 0102 0001 0000 0000 0000 0000
0000010 0001 003e 0001 0000 0000 0000 0000 0000
...

Now compare that to your output:

mike@mike-VirtualBox:~/C$ ./a.out 
127 69 76 70 2 1 1 0 0 0

hmm, maybe change the printf to a %x to make this a little clearer:

mike@mike-VirtualBox:~/C$ ./a.out 
7F 45 4C 46 2 1 1 0 0 0

Hey, look! The data matches up now^*. Awesome, we must be reading the binary file correctly!

^{*Note the bytes are just swapped on the output but that data is correct, you can adjust for this sort of thing}

Just add this top of your controller.

use DB;

Works for all browsers and all versions:

JS

jQuery(document).ready(function () {    
    var widthOfSelect = $("#first").width();
    widthOfSelect = widthOfSelect - 13;
    //alert(widthOfSelect);
    jQuery('#first').wrap("<div id='sss' style='width: "+widthOfSelect+"px; overflow: hidden; border-right: #000 1px solid;' width=20></div>");
});

HTML

<select class="first" id="first">
  <option>option1</option>
  <option>option2</option>
  <option>option3</option>
</select>

If globally installed then

"scripts": {
    "start": "nodemon FileName.js(server.js)",
},

Make sure you have installed nodemon globally:

npm install -g nodemon

Finally, if you are a Windows user, make sure that the security restriction of the Windows PowerShell is enabled.

Are you concerned about the profile picture size? at the time of implementing login with Facebook using PHP. We’ll show you the simple way to get large size profile picture in Facebook PHP SDK. Also, you can get the custom size image of Facebook profile.

Set the profile picture dimension by using the following line of code.

$userProfile = $facebook->api('/me?fields=picture.width(400).height(400)');

check this post:http://www.codexworld.com/how-to-guides/get-large-size-profile-picture-in-facebook-php-sdk/

One interesting difference in ng-if and ng-show is:

SECURITY

DOM elements present in ng-if block will not be rendered in case of its value as false

where as in case of ng-show, the user can open your Inspect Element Window and set its value to TRUE.

And with a whoop, whole contents that was meant to be hidden gets displayed, which is a security breach. :)

to add scroll u need to define max-height of your div and then add overflow-y

so do something like this

.my_scroll_div{
    overflow-y: auto;
    max-height: 100px;
}

This worked for me perfectly in bootstrap 4.4.1 !!

.nav-pills > li > a.active{
  background-color:#46b3e6 !important;
  color:white !important;
}

  .nav-pills > li.active > a:hover {
  background-color:#46b3e6 !important;
  color:white !important;
        }

.nav-link-color {
  color: #46b3e6;
}

I had the same problem. Solved it by using a javascript library called FileSaver

Just call

saveAs(file, 'filename');

Full http post request:

$http.post('apiUrl', myObject, { responseType: 'arraybuffer' })
  .success(function(data) {
            var file = new Blob([data], { type: 'application/pdf' });
            saveAs(file, 'filename.pdf');
        });

vim +21490go script.py

From the command line will open the file and take you to position 21490 in the buffer.

Triggering it from the command line like this allows you to automate a script to parse the exception message and open the file to the problem position.

Excerpt from man vim:

+{command}

-c {command}

{command} will be executed after the first file has been read. {command} is interpreted as an Ex command. If the {command} contains spaces it must be enclosed in double quotes (this depends on the shell that is used).

You cannot open new fragments. Fragments need to be always hosted by an activity. If the fragment is in the same activity (eg tabs) then the back key navigation is going to be tricky I am assuming that you want to open a new screen with that fragment.

So you would simply create a new activity and put the new fragment in there. That activity would then react to the intent either explicitly via the activity class or implicitly via intent filters.

Windows: setting notepad as the default commit message editor

git config --global core.editor notepad.exe

Hit Ctrl+S to save your commit message. To discard, just close the notepad window without saving.

In case you hit the shortcut for save, then decide to abort, go to File->Save as, and in the dialog that opens, change "Save as type" to "All files (*.*)". You will see a file named "COMMIT_EDITMSG". Delete it, and close notepad window.

Edit: Alternatively, and more easily, delete all the contents from the open notepad window and hit save. (thanks mwfearnley for the comment!)

I think for small write-ups such as commit messages notepad serves best, because it is simple, is there with windows, opens up in no time. Even your sublime may take a second or two to get fired up when you have a load of plugins and stuff.

require(reshape2)

T <- melt(df, id = c("A"))

T <- dcast(T, A ~ variable, sum)

I am not certain the exact advantages over aggregate.

I guess you should install CA certificate form one if authority canter:

ssl_trusted_certificate ssl/SSL_CA_Bundle.pem;

In the detached 'Tool Options' window, click on the red 'X' in the upper right corner to get rid of the window. Then on the main Gimp screen, click on 'Windows,' then 'Dockable Dialogs.' The first entry on its list will be 'Tool Options,' so click on that. Then, Tool Options will appear as a tab in the window on the right side of the screen, along with layers and undo history. Click and drag that tab over to the toolbox window on hte left and drop it inside. The tool options will again be docked in the toolbox.

Don't forget to handle errors! The following code is based on Augusto Roman's answer.

var http = require('http');
var fs = require('fs');

var download = function(url, dest, cb) {
  var file = fs.createWriteStream(dest);
  var request = http.get(url, function(response) {
    response.pipe(file);
    file.on('finish', function() {
      file.close(cb);  // close() is async, call cb after close completes.
    });
  }).on('error', function(err) { // Handle errors
    fs.unlink(dest); // Delete the file async. (But we don't check the result)
    if (cb) cb(err.message);
  });
};

This problem comes from the CSRF token verification which fails. So either you're not posting one or you're posting an incorrect one.

The reason it works for GET is that for a GET route in Laravel, there is no CSRF token posted.

You can either post a CSRF token in your form by calling:

{{ csrf_field() }}

Or exclude your route (NOT RECOMMENDED DUE TO SECURITY) in app/Http/Middleware/VerifyCsrfToken.php:

protected $except = [
    'your/route'
];

Cstr() is compiled inline for better performance.

CType allows for casts between types if a conversion operator is defined

ToString() Between base type and string throws an exception if conversion is not possible.

TryParse() From String to base typeif possible otherwise returns false

DirectCast used if the types are related via inheritance or share a common interface , will throw an exception if the cast is not possible, trycast will return nothing in this instance

Further to Nick Bisby's answer, if you get this problem using HAML in rails and you have applied Roberto Barros' fix here:

I replaced the require in the "bootstrap_and_overrides.css" to:

=require twitter-bootstrap-static/bootstrap.css.erb

(See https://github.com/seyhunak/twitter-bootstrap-rails/issues/91)

... you need to put the body CSS before the require statement as follows:

@import "twitter/bootstrap/bootstrap";
body { padding-top: 40px; }
@import "twitter/bootstrap/responsive";
=require twitter-bootstrap-static/bootstrap.css.erb

If the require statement is before the body CSS, it will not take effect.

This is an old question, but you can now write using statements without needing to block each one. They will be disposed of in reverse order when the containing block is finished.

using var responseStream = response.GetResponseStream();
using var reader = new StreamReader(responseStream);
using var writer = new StreamWriter(filename);

int chunkSize = 1024;
while (!reader.EndOfStream)
{
    char[] buffer = new char[chunkSize];
    int count = reader.Read(buffer, 0, chunkSize);
    if (count != 0)
    {
        writer.Write(buffer, 0, count);
    }

You could also put non-breaking spaces ( ) in lieu of the spaces so that they're forced to stay together.

How do I wrap this line of text
- asked by Peter 2 days ago

If your npm version is lower than version 5 then install the higher version for getting the automatic generation of package-lock.json.

Example: Upgrade your current npm to version 6.14.0

npm i -g [email protected]

You could view the latest npm version list by

npm view npm versions

If you would like to make the command once for your entire site, instead of having to do it after every link. Try this place within the Head of your web site and bingo.

If it's still of interest, here is an answer to a similar question: Convert HTTP Proxy to HTTPS Proxy in Twisted

To answer the second part of the question:

If yes, what kind of proxy server allows this?

Out of the box, most proxy servers will be configured to allow HTTPS connections only to port 443, so https URIs with custom ports wouldn't work. This is generally configurable, depending on the proxy server. Squid and TinyProxy support this, for example.

To resume the working solutions in VisualStudio 2013 and 2015 too:

Add an include-path to the current project only

In Solution Explorer (a palette-window of the VisualStudio-mainwindow), open the shortcut menu for the project and choose Properties, and then in the left pane of the Property Pages dialog box, expand Configuration Properties and select VC++ Directories. Additional include- or lib-paths are specifyable there.

Its the what Stackunderflow and user1741137 say in the answers above. Its the what Microsoft explains in MSDN too.

Add an include-path to every new project automatically

Its the question, what Jay Elston is asking in a comment above and what is a very obvious and burning question in my eyes, what seems to be nonanswered here yet.

There exist regular ways to do it in VisualStudio (see CurlyBrace.com), what in my experience are not working properly. In the sense, that it works only once, and thereafter, it is no more expandable and nomore removable. The approach of Steve Wilkinson in another close related thread of StackOverflow, editing the Microsoft-Factory-XML-file in the ‘program files’ - directory is probably a risky hack, as it isnt expected by Microsoft to meet there something foreign. The effect is potentally unpredictable. Well, I like rather to judge it risky not much, but anyway the best way to make VisualStudio work incomprehensible at least for someone else.

The what is working fine compared to, is the editing the corresponding User-XML-file:

C:\Users\UserName\AppData\Local\Microsoft\MSBuild\v4.0\Microsoft.Cpp.Win32.user.props

or/and

C:\Users\UserName\AppData\Local\Microsoft\MSBuild\v4.0\Microsoft.Cpp.x64.user.props

For example:

<?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <ImportGroup Label="PropertySheets">
  </ImportGroup>
  <PropertyGroup Label="UserMacros" />
  <PropertyGroup>
    <IncludePath>C:\any-name\include;$(IncludePath)</IncludePath>
    <LibraryPath>C:\any-name\lib;$(LibraryPath)</LibraryPath>
  </PropertyGroup>
  <ItemDefinitionGroup />
  <ItemGroup />
</Project>

Where the directory ‘C:\any-name\include’ will get prepended to the present include-path and the directory ‘C:\any-name\lib’ to the library-path. Here, we can edit it ago in an extending and removing sense and remove it all, removing thewhole content of the tag .

Its the what makes VisualStudio itself, doing it in the regular way what CurlyBrace describes. As said, it isnt editable in the CurlyBrace-way thereafter nomore, but in the XML-editing-way it is.

For more insight, see Brian Tyler@MSDN-Blog 2009, what is admittedly not very fresh, but always the what Microsoft is linking to.

You need to add a 640x1136 pixels PNG image ([email protected]) as a 4 inch default splash image of your project, and it will use extra spaces (without efforts on simple table based applications, games will require more efforts).

I've created a small UIDevice category in order to deal with all screen resolutions. You can get it here, but the code is as follows:

File UIDevice+Resolutions.h:

enum {
    UIDeviceResolution_Unknown           = 0,
    UIDeviceResolution_iPhoneStandard    = 1,    // iPhone 1,3,3GS Standard Display  (320x480px)
    UIDeviceResolution_iPhoneRetina4    = 2,    // iPhone 4,4S Retina Display 3.5"  (640x960px)
    UIDeviceResolution_iPhoneRetina5     = 3,    // iPhone 5 Retina Display 4"       (640x1136px)
    UIDeviceResolution_iPadStandard      = 4,    // iPad 1,2,mini Standard Display   (1024x768px)
    UIDeviceResolution_iPadRetina        = 5     // iPad 3 Retina Display            (2048x1536px)
}; typedef NSUInteger UIDeviceResolution;

@interface UIDevice (Resolutions)

- (UIDeviceResolution)resolution;

NSString *NSStringFromResolution(UIDeviceResolution resolution);

@end

File UIDevice+Resolutions.m:

#import "UIDevice+Resolutions.h"

@implementation UIDevice (Resolutions)

- (UIDeviceResolution)resolution
{
    UIDeviceResolution resolution = UIDeviceResolution_Unknown;
    UIScreen *mainScreen = [UIScreen mainScreen];
    CGFloat scale = ([mainScreen respondsToSelector:@selector(scale)] ? mainScreen.scale : 1.0f);
    CGFloat pixelHeight = (CGRectGetHeight(mainScreen.bounds) * scale);

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone){
        if (scale == 2.0f) {
            if (pixelHeight == 960.0f)
                resolution = UIDeviceResolution_iPhoneRetina4;
            else if (pixelHeight == 1136.0f)
                resolution = UIDeviceResolution_iPhoneRetina5;

        } else if (scale == 1.0f && pixelHeight == 480.0f)
            resolution = UIDeviceResolution_iPhoneStandard;

    } else {
        if (scale == 2.0f && pixelHeight == 2048.0f) {
            resolution = UIDeviceResolution_iPadRetina;

        } else if (scale == 1.0f && pixelHeight == 1024.0f) {
            resolution = UIDeviceResolution_iPadStandard;
        }
    }

    return resolution;
 }

 @end

This is how you need to use this code.

1) Add the above UIDevice+Resolutions.h & UIDevice+Resolutions.m files to your project

2) Add the line #import "UIDevice+Resolutions.h" to your ViewController.m

3) Add this code to check what versions of device you are dealing with

int valueDevice = [[UIDevice currentDevice] resolution];

    NSLog(@"valueDevice: %d ...", valueDevice);

    if (valueDevice == 0)
    {
        //unknow device - you got me!
    }
    else if (valueDevice == 1)
    {
        //standard iphone 3GS and lower
    }
    else if (valueDevice == 2)
    {
        //iphone 4 & 4S
    }
    else if (valueDevice == 3)
    {
        //iphone 5
    }
    else if (valueDevice == 4)
    {
        //ipad 2
    }
    else if (valueDevice == 5)
    {
        //ipad 3 - retina display
    }

Check this example of post the array of different types

function PostArray() {
    var myObj = [
        { 'fstName': 'name 1', 'lastName': 'last name 1', 'age': 32 }
      , { 'fstName': 'name 2', 'lastName': 'last name 1', 'age': 33 }
    ];

    var postData = JSON.stringify({ lst: myObj });
    console.log(postData);

    $.ajax({
        type: "POST",
        url: urlWebMethods + "/getNames",
        data: postData,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (response) {
            alert(response.d);
        },
        failure: function (msg) {
            alert(msg.d);
        }
    });
}

If using a WebMethod in C# you can retrieve the data like this

[WebMethod]
    public static string getNames(IEnumerable<object> lst)
    {
        string names = "";
        try
        {
            foreach (object item in lst)
            {
                Type myType = item.GetType();
                IList<PropertyInfo> props = new List<PropertyInfo>(myType.GetProperties());

                foreach (PropertyInfo prop in props)
                {
                    if(prop.Name == "Values")
                    {
                        Dictionary<string, object> dic = item as Dictionary<string, object>;
                        names += dic["fstName"];
                    }
                }
            }
        }
        catch (Exception ex)
        {
             names = "-1";
        }
        return names;
    }

Example in POST an array of objects with $.ajax to C# WebMethod

I agree with the sentiment in the comments above — this can be pretty annoying. We can only hope you give the user the option to turn the music off.

However...

audio { display:none;}

<audio autoplay="true" src="https://upload.wikimedia.org/wikipedia/commons/c/c8/Example.ogg">

The css hides the audio element, and the autoplay="true" plays it automatically.

It depends what is a use of those tables, but you might consider putting trigger on original table on insert and update. When insert or update is done, update the second table based on only one item from the original table. It will be quicker.

There is even easier way how to work with JSONP using jQuery

$.getJSON("http://example.com/something.json?callback=?", function(result){
   //response data are now in the result variable
   alert(result);
});

The ? on the end of the URL tells jQuery that it is a JSONP request instead of JSON. jQuery registers and calls the callback function automatically.

For more detail refer to the jQuery.getJSON documentation.

In my case, I Installed SQL Express 2012 and the problem raise after I reboot my PC. I solved so:

I go to Services -> SQL Server (SQLEXPRESS) and I see that was stopped. I started and It's say an login error. In properties, Tab Log On, I change it to Local System account , then I can start the SQL service.

Then to test it, I go to SQL Server Management Studio and I connect to .\SQLEXPRESS and it works!

Do you need to fake an anchor click? From the thickbox site:

ThickBox can be invoked from a link element, input element (typically a button), and the area element (image maps).

If that is acceptable it should be as easy as putting the thickbox class on the input itself:

<input id="thickboxButton" type="button" class="thickbox" value="Click me">

If not, I would recommend using Firebug and placing a breakpoint in the onclick method of the anchor element to see if it's only triggered on the first click.

Edit:

Okay, I had to try it for myself and for me pretty much exactly your code worked in both Chrome and Firefox:

<html>
<head>
<link rel="stylesheet" href="thickbox.css" type="text/css" media="screen" />
</head>
<body>
<script src="jquery-latest.pack.js" type="text/javascript"></script>
<script src="thickbox.js" type="text/javascript"></script>
<input onclick="$('#thickboxId').click();" type="button" value="Click me">
<a id="thickboxId" href="myScript.php" class="thickbox" title="">Link</a>
</body>
</html>

The window pop ups no matter if I click the input or the anchor element. If the above code works for you, I suggest your error lies elsewhere and that you try to isolate the problem.

Another possibly is that we are using different versions of jquery/thickbox. I am using what I got from the thickbox page - jquery 1.3.2 and thickbox 3.1.

Your Maven is reading Java version as 1.6.0_65, Where as the pom.xml says the version is 1.7.

Try installing the required verison.

If already installed check your $JAVA_HOME environment variable, it should contain the path of Java JDK 7. If you dont find it, fix your environment variable.

also remove the lines

 <fork>true</fork>
     <executable>${JAVA_1_7_HOME}/bin/javac</executable>

from the pom.xml

if you are a exists project, maybe should execute npm install.

Code below (taken from my blog article - http://todayguesswhat.blogspot.com/2021/01/manually-verifying-rsa-sha-signature-in.html ) is hopefully helpful in understanding what is present in a standard SHA with RSA signature. This should work in standard Oracle JDK and does not require Bouncy Castle libraries. It is using the sun.security classes to process the decrypted signature contents - you could just as easily manually parse.

In the example below, the message digest algorithm is SHA-512 which produces a 64 byte (512-bit) checksum.

SHA-1 would be pretty similar - but producing a 20-byte (160-bit) checksum.

        PrivateKey privateKey = keyPair.getPrivate();
        PublicKey publicKey = keyPair.getPublic();

        String data = "hello oracle";
        byte[] dataBytes = data.getBytes("UTF8");

        Signature signer = Signature.getInstance("SHA512withRSA");
        signer.initSign(privateKey);

        signer.update(dataBytes);

        byte[] signature = signer.sign(); // signature bytes of the signing operation's result.

        Signature verifier = Signature.getInstance("SHA512withRSA");
        verifier.initVerify(publicKey);
        verifier.update(dataBytes);

        boolean verified = verifier.verify(signature);
        if (verified)
        {

        }

You are not getting value of $id=$_GET['id'];

And you are using it (before it gets initialised).

Use php's in built isset() function to check whether the variable is defied or not.

So, please update the line to:

$id = isset($_GET['id']) ? $_GET['id'] : '';

<edit>

Just noticed you said mod_rewrite.s instead of mod_rewrite.so - hope that's a typo in your question and not in the httpd.conf file! :)

</edit>

I'm more used to using Apache on Linux, but I had to do this the other day.

First off, take a look in your Apache install directory. (I'll be assuming you installed it to "C:\Program Files" here)

Take a look in the folder: "C:\Program Files\Apache Software Foundation\Apache2.2\modules" and make sure that there's a file called mod_rewrite.so in there. (It should be, it's provided as part of the default install.

Next, open up "C:\Program Files\Apache Software Foundation\Apache2.2\conf" and open httpd.conf. Make sure the line:

#LoadModule rewrite_module modules/mod_rewrite.so

is uncommented:

LoadModule rewrite_module modules/mod_rewrite.so

Also, if you want to enable the RewriteEngine by default, you might want to add something like

<IfModule mod_rewrite>
    RewriteEngine On
</IfModule>

to the end of your httpd.conf file.

If not, make sure you specify

RewriteEngine On

somewhere in your .htaccess file.

The error is because fName is included in the SELECT list, but is not included in a GROUP BY clause and is not part of an aggregate function (Count(), Min(), Max(), Sum(), etc.)

You can fix that problem by including fName in a GROUP BY. But then you will face the same issue with surname. So put both in the GROUP BY:

SELECT
    fName,
    surname,
    Count(*) AS num_rows
FROM
    author
    INNER JOIN book
    ON author.aID = book.authorID;
GROUP BY
    fName,
    surname

Note I used Count(*) where you wanted SUM(orders.quantity). However, orders isn't included in the FROM section of your query, so you must include it before you can Sum() one of its fields.

If you have Access available, build the query in the query designer. It can help you understand what features are possible and apply the correct Access SQL syntax.

While it may work on some platforms, be aware that platform.architecture is not always a reliable way to determine whether python is running in 32-bit or 64-bit. In particular, on some OS X multi-architecture builds, the same executable file may be capable of running in either mode, as the example below demonstrates. The quickest safe multi-platform approach is to test sys.maxsize on Python 2.6, 2.7, Python 3.x.

$ arch -i386 /usr/local/bin/python2.7
Python 2.7.9 (v2.7.9:648dcafa7e5f, Dec 10 2014, 10:10:46)

If you are getting a timeout while on the table designer, change the "Transaction time-out after" value under Tools --> Options --> Designers --> Table and Database Designers

This will get rid of this message: "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."

You should return only one column and one row in the where query where you assign the returned value to a variable. Example:

select * from table1 where Date in (select * from Dates) -- Wrong
select * from table1 where Date in (select Column1,Column2 from Dates) -- Wrong
select * from table1 where Date in (select Column1 from Dates) -- OK

this works in all browsers (IE is an oddball)

setTimeout( (function(x) {
return function() {
        postinsql(x);
    };
})(topicId) , 4000);

That's called SQL INJECTION. The ' tries to open/close a string in your mysql query. You should always escape any string that gets into your queries.

for example,

instead of this:

"VALUES ('$sender_id') "

do this:

"VALUES ('". mysql_real_escape_string($sender_id)  ."') "

(or equivalent, of course)

However, it's better to automate this, using PDO, named parameters, prepared statements or many other ways. Research about this and SQL Injection (here you have some techniques).

Hope it helps. Cheers

I found the OpenSSL answer given above didn't work for me, but the following did, working with a CRT file sourced from windows.

If you're using gnu sed then you can use \x0A for newline:

sed 's/:/\x0A/g' ~/Desktop/myfile.txt

A self-made solution:

bool isNumeric(const char *str) 
{
    while(*str != '\0')
    {
        if(*str < '0' || *str > '9')
            return false;
        str++;
    }
    return true;
}

Note that this solution should not be used in production-code, because it has severe limitations. But I like it for understanding C-Strings and ASCII.

This single command line is easy to remember:

npx kill-port 3000

If you are sure that this change is suitable for the environment you're working in: set the FK conditions on the secondary tables to UPDATE CASCADING.

For example, if using SSMS as GUI:

1. right click on the key
2. select Modify
3. Fold out 'INSERT And UPDATE Specific'
4. For 'Update Rule', select Cascade.
5. Close the dialog and save the key.

When you then update a value in the PK column in your primary table, the FK references in the other tables will be updated to point at the new value, preserving data integrity.

1. This is not done in PHP. It's part of the <head> tags in a HTML page.
2. That icon is called a favicon. According to Wikipedia:

   A favicon (short for favorites icon), also known as a shortcut icon, website icon, URL icon, or bookmark icon is a 16×16 or 32×32 pixel square icon associated with a particular website or webpage.

3. Adding it is easy. Just add an .ico image file that is either 16x16 pixels or 32x32 pixels. Then, in the web pages, add <link rel="shortcut icon" href="favicon.ico" type="image/x-icon"> to the <head> element.
4. You can easily generate favicons here.

yet another solution uses tr:

echo $testVar | tr -d '\r'
cat myscript | tr -d '\r'

the option -d stands for delete.

What about new Array(51).join('0').split('')?

This will get the 'floor' of a datetime object stored in tm rounded to the 10 minute mark before tm.

tm = tm - datetime.timedelta(minutes=tm.minute % 10,
                             seconds=tm.second,
                             microseconds=tm.microsecond)

If you want classic rounding to the nearest 10 minute mark, do this:

discard = datetime.timedelta(minutes=tm.minute % 10,
                             seconds=tm.second,
                             microseconds=tm.microsecond)
tm -= discard
if discard >= datetime.timedelta(minutes=5):
    tm += datetime.timedelta(minutes=10)

or this:

tm += datetime.timedelta(minutes=5)
tm -= datetime.timedelta(minutes=tm.minute % 10,
                         seconds=tm.second,
                         microseconds=tm.microsecond)

You can extend multiple Interfaces but you cannot extend multiple classes.

The reason that it is not possible in Java to extending multiple classes, is the bad experience from C++ where this is possible.

The alternative for multipe inheritance is that a class can implement multiple interfaces (or an Interface can extend multiple Interfaces)

you can create options menu like below:

Menu XML code:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/Menu_AboutUs"
        android:icon="@drawable/ic_about_us_over_black"
        android:title="About US"/>
    <item
        android:id="@+id/Menu_LogOutMenu"
        android:icon="@drawable/ic_arrow_forward_black"
        android:title="Logout"/>
</menu>

How you can get the menu from MENU XML(Convert menu XML to java):

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.my_options_menu,menu);
        return super.onCreateOptionsMenu(menu);
    }

How to get Selected Item from Menu:

@Override
    public boolean onOptionsItemSelected(@NonNull MenuItem item) {
        switch (item.getItemId()){

            case R.id.Menu_AboutUs:
                //About US
                break;

            case R.id.Menu_LogOutMenu:
                //Do Logout
                break;
        }
        return super.onOptionsItemSelected(item);
    }

Using unique():

dat <- data.frame(id=c(1,1,3),id2=c(1,1,4),somevalue=c("x","y","z"))    
dat[row.names(unique(dat[,c("id", "id2")])),]

Use the in keyword without is.

if "x" in dog:
    print "Yes!"

If you'd like to check for the non-existence of a character, use not in:

if "x" not in dog:
    print "No!"

For current date just use UNIX_TIMESTAMP() in your MySQL query.

To bring more prominence to the useful comment by @johanvdw:

If you want to ensure your your javac file path is always know when cygwin starts, you may edit your .bash_profile file. In this example you would add export PATH=$PATH:"/cygdrive/C/Program Files/Java/jdk1.6.0_23/bin/" somewhere in the file.

When Cygwin starts, it'll search directories in PATH and this one for executable files to run.

Just to add Python 3 f-string solution

prob = 1.0/3.0
print(f"{prob:.0%}")

Example: ajshdjashdjashdlasdlhdlSTARTasdasdsdaasdENDaknsdklansdlknaldknaaklsdn

1) START\w*END return: STARTasdasdsdaasdEND - will give you words between START and END

2) START\d*END return: START12121212END - will give you numbers between START and END

3) START\d*_\d*END return: START1212_1212END - will give you numbers between START and END having _

Your problem is simple:

names = {'John', 'Joe', 'Steve'}
for names = 1, 3 do
  print (names)
end

This code first declares a global variable called names. Then, you start a for loop. The for loop declares a local variable that just happens to be called names too; the fact that a variable had previously been defined with names is entirely irrelevant. Any use of names inside the for loop will refer to the local one, not the global one.

The for loop says that the inner part of the loop will be called with names = 1, then names = 2, and finally names = 3. The for loop declares a counter that counts from the first number to the last, and it will call the inner code once for each value it counts.

What you actually wanted was something like this:

names = {'John', 'Joe', 'Steve'}
for nameCount = 1, 3 do
  print (names[nameCount])
end

The [] syntax is how you access the members of a Lua table. Lua tables map "keys" to "values". Your array automatically creates keys of integer type, which increase. So the key associated with "Joe" in the table is 2 (Lua indices always start at 1).

Therefore, you need a for loop that counts from 1 to 3, which you get. You use the count variable to access the element from the table.

However, this has a flaw. What happens if you remove one of the elements from the list?

names = {'John', 'Joe'}
for nameCount = 1, 3 do
  print (names[nameCount])
end

Now, we get John Joe nil, because attempting to access values from a table that don't exist results in nil. To prevent this, we need to count from 1 to the length of the table:

names = {'John', 'Joe'}
for nameCount = 1, #names do
  print (names[nameCount])
end

The # is the length operator. It works on tables and strings, returning the length of either. Now, no matter how large or small names gets, this will always work.

However, there is a more convenient way to iterate through an array of items:

names = {'John', 'Joe', 'Steve'}
for i, name in ipairs(names) do
  print (name)
end

ipairs is a Lua standard function that iterates over a list. This style of for loop, the iterator for loop, uses this kind of iterator function. The i value is the index of the entry in the array. The name value is the value at that index. So it basically does a lot of grunt work for you.

I've published a Python [3] tree implementation on my site: http://www.quesucede.com/page/show/id/python_3_tree_implementation.

The syntax of ng-style is not quite that. It accepts a dictionary of keys (attribute names) and values (the value they should take, an empty string unsets them) rather than only a string. I think what you want is this:

<div ng-style="{ 'width' : width, 'background' : bgColor }"></div>

And then in your controller:

$scope.width = '900px';
$scope.bgColor = 'red';

This preserves the separation of template and the controller: the controller holds the semantic values while the template maps them to the correct attribute name.

If you're just after console logging here's what I'd do:

export default class App extends Component {
  componentDidMount() {
    console.log('I was triggered during componentDidMount')
  }

  render() {
    console.log('I was triggered during render')
    return ( 
      <div> I am the App component </div>
    )
  }
}

Shouldn't be any need for those packages just to do console logging.

Here you have example how to set the readonly attribute:

<form action="demo_form.asp">_x000D_
  Country: <input type="text" name="country" value="Norway" readonly><br>_x000D_
  <input type="submit" value="Submit">_x000D_
</form>

How about,

select
        col1, 
        col2, 
        null col3, 
        null col4 
    from Table1
union all
select 
        null col1, 
        null col2,
        col4 col3, 
        col5 col4 
    from Table2;

I've had the same issue. Try to:

Right click on the project and select Clean, then right click on it again and select Rebuild and run the project to see if it worked.

Attention, this is only advised if your runOnceOnStartup method depends on a fully initialized spring context. For example: you wan to call a dao with transaction demarcation

You can also use a scheduled method with fixedDelay set very high

@Scheduled(fixedDelay = Long.MAX_VALUE)
public void runOnceOnStartup() {
    dosomething();
}

This has the advantage that the whole application is wired up (Transactions, Dao, ...)

seen in Scheduling tasks to run once, using the Spring task namespace

Worth knowing:

If you are running an ENTRYPOINT script ... the script will work with the shebang

#!/bin/bash -x

But will stop the container from stopping with

#!/bin/bash -xe
