If another part of your code has already made a connection with the same socket and UUID, you get this error.

Just posting because the root cause for my case has not been described her.

In my case the problem was that "assets/js/fuelux/treeview/fuelux.min.js" was adding a constructor .datepicker(), so that was overriding the assets/js/datetime/bootstrap-datepicker.js

just moving the

to be just before the $('.date-picker') solved my problem.

Typing sp_helpserver will give you a list. As others have noted, there are multiple ways, some with alias' and such. This stored proc may return multiple lines but could get you closer to your answer.

Use position: relative on the parent element.

Also note that had you not added any position attributes to any of the divs you wouldn't have seen this behavior. Juan explains further.

Basically, add this to the pom.xml:

When you execute a method (i.e. function assigned to an object), inside it you can use this variable to refer to this object, for example:

var obj = {_x000D_
  someProperty: true,_x000D_
  someMethod: function() {_x000D_
    console.log(this.someProperty);_x000D_
  }_x000D_
};_x000D_
obj.someMethod(); // logs true

If you assign a method from one object to another, its this variable refers to the new object, for example:

var obj = {_x000D_
  someProperty: true,_x000D_
  someMethod: function() {_x000D_
    console.log(this.someProperty);_x000D_
  }_x000D_
};_x000D_
_x000D_
var anotherObj = {_x000D_
  someProperty: false,_x000D_
  someMethod: obj.someMethod_x000D_
};_x000D_
_x000D_
anotherObj.someMethod(); // logs false

The same thing happens when you assign requestAnimationFrame method of window to another object. Native functions, such as this, has build-in protection from executing it in other context.

There is a Function.prototype.call() function, which allows you to call a function in another context. You just have to pass it (the object which will be used as context) as a first parameter to this method. For example alert.call({}) gives TypeError: Illegal invocation. However, alert.call(window) works fine, because now alert is executed in its original scope.

If you use .call() with your object like that:

support.animationFrame.call(window, function() {});

it works fine, because requestAnimationFrame is executed in scope of window instead of your object.

However, using .call() every time you want to call this method, isn't very elegant solution. Instead, you can use Function.prototype.bind(). It has similar effect to .call(), but instead of calling the function, it creates a new function which will always be called in specified context. For example:

window.someProperty = true;_x000D_
var obj = {_x000D_
  someProperty: false,_x000D_
  someMethod: function() {_x000D_
    console.log(this.someProperty);_x000D_
  }_x000D_
};_x000D_
_x000D_
var someMethodInWindowContext = obj.someMethod.bind(window);_x000D_
someMethodInWindowContext(); // logs true

The only downside of Function.prototype.bind() is that it's a part of ECMAScript 5, which is not supported in IE <= 8. Fortunately, there is a polyfill on MDN.

As you probably already figured out, you can use .bind() to always execute requestAnimationFrame in context of window. Your code could look like this:

var support = {
    animationFrame: (window.requestAnimationFrame ||
        window.mozRequestAnimationFrame ||
        window.webkitRequestAnimationFrame ||
        window.msRequestAnimationFrame ||
        window.oRequestAnimationFrame).bind(window)
};

Then you can simply use support.animationFrame(function() {});.

An example of retrieving data from a table having columns column1, column2 ,column3 column4, cloumn1 and 2 hold int values and column 3 and 4 hold varchar(10)

Sounds like a homework problem. scanf() is the wrong function to use for the problem. I'd recommend getchar() or getch().

Note: I'm purposefully not solving the problem since this seems like homework, instead just pointing you in the right direction.

I was hunting around for an answer to this question. I found this helpful. The pattern wasn't apparent in the documentation for with_items.

https://github.com/ansible/ansible/issues/39389

- hosts: localhost
  connection: local
  gather_facts: no

  tasks:
    - name: set_fact
      set_fact:
        foo: "{{ foo }} + [ '{{ item }}' ]"
      with_items:
        - "one"
        - "two"
        - "three"
      vars:
        foo: []

    - name: Print the var
      debug:
        var: foo

I suppose you have figured it out by now. The answer is hidden in your first mail itself.

The make command by default looks for makefile, Makefile, and GNUMakefile as the input file and you are having Makefile.txt in your folder. Just remove the file extension (.txt) and it should work.

Bootstrap 4: navbar Active State working, just use .navbar-nav .nav-link classes

 $(function () {
  // this will get the full URL at the address bar
  var url = window.location.href;
  // passes on every "a" tag
  $(".navbar-nav .nav-link").each(function () {
    // checks if its the same on the address bar
    if (url == (this.href)) {
      $(this).closest("li").addClass("active");
      //for making parent of submenu active
      $(this).closest("li").parent().parent().addClass("active");
    }
  });
});

UUID is similar in notion to port numbers in Internet. However, the difference between Bluetooth and the Internet is that, in Bluetooth, port numbers are assigned dynamically by the SDP (service discovery protocol) server during runtime where each UUID is given a port number. Other devices will ask the SDP server, who is registered under a reserved port number, about the available services on the device and it will reply with different services distinguishable from each other by being registered under different UUIDs.

In Apache 2.4 the old access authorisation syntax has been deprecated and replaced by a new system using Require.

What you want then is something like the following:

<Directory "/labs/Projects/Nebula/">
  Options All
  AllowOverride All
  <RequireAny>
    Require local
    Require ip 192.168.1
  </RequireAny>
</Directory>

This will allow connections that originate either from the local host or from ip addresses that start with "192.168.1".

There is also a new module available that makes Apache 2.4 recognise the old syntax if you don't want to update your configuration right away:

sudo a2enmod access_compat

This is what I ended up doing, since we have a web app that has multiple users that are not under our control...(@DannyBeckett I know this isn't an exact answer to your question, but the people that are looking at your question might be helped by this.) You can at least detect if they are not seeing the dialogs. There are few things you most likely want to change like the time to display, or what you are actually displaying. Remember this will only notify the user that they are have managed to click that little checkbox.

window.nativeAlert = window.alert;
window.alert = function (message) {
    var timeBefore = new Date();
    var confirmBool = nativeAlert(message);
    var timeAfter = new Date();
    if ((timeAfter - timeBefore) < 350) {
        MySpecialDialog("You have alerts turned off");
    }
}

window.nativeConfirm = window.confirm;
window.confirm = function (message) {
    var timeBefore = new Date();
    var confirmBool = nativeConfirm(message);
    var timeAfter = new Date();
    if ((timeAfter - timeBefore) < 350) {
        MySpecialDialog("You have confirms turned off");
    }
    return confirmBool;
}

Obviously I have set the time to 3.5 milliseconds. But after some testing we were only able to click or close the dialogs in about 5 milliseconds plus.

In MVVM (wich makes a lot of things a lot easier - you should try it) you would have two properties in your ViewModel Text that is bound to your TextBox and you would have an ICommand property Apply (or similar) that is bound to the button:

<Button Command="Apply">Apply</Button>

The ICommand interface has a Method CanExecute that is where you return true if (!string.IsNullOrWhiteSpace(this.Text). The rest is done by WPF for you (enabling/disabling, executing the actual command on click).

The linked article explains it in detail.

Here's another way to do it in VBA.

Function ConvertToArray(ByVal value As String)
    value = StrConv(value, vbUnicode)
    ConvertToArray = Split(Left(value, Len(value) - 1), vbNullChar)
End Function
Sub example()
    Dim originalString As String
    originalString = "hi there"
    Dim myArray() As String
    myArray = ConvertToArray(originalString)
End Sub

There is a module on npm called mssqlhelper

You can install it to your project by npm i mssqlhelper

Example of connecting and performing a query:

var db = require('./index');

db.config({
    host: '192.168.1.100'
    ,port: 1433
    ,userName: 'sa'
    ,password: '123'
    ,database:'testdb'
});

db.query(
    'select @Param1 Param1,@Param2 Param2'
    ,{
         Param1: { type : 'NVarChar', size: 7,value : 'myvalue' }
         ,Param2: { type : 'Int',value : 321 }
    }
    ,function(res){
        if(res.err)throw new Error('database error:'+res.err.msg);
        var rows = res.tables[0].rows;
        for (var i = 0; i < rows.length; i++) {
            console.log(rows[i].getValue(0),rows[i].getValue('Param2'));
        }
    }
);

If you don't want it to add it to a link, you can just enclose it within a span and that would work.

<span id='clickableAwesomeFont'><i class="fa fa-behance-square fa-4x"></span>

in your css, then you can:

#clickableAwesomeFont {
     cursor: pointer
}

Then in java script, you can just add a click handler.

In cases where it's actually not a link, I think this is much cleaner and using a link would be changing its semantics and abusing its meaning.

If you look at xhtml1-strict.dtd, you'll see

<!ELEMENT li %Flow;>
<!ENTITY % Flow "(#PCDATA | %block; | form | %inline; | %misc;)*">
<!ENTITY % block
     "p | %heading; | div | %lists; | %blocktext; | fieldset | table">

Thus div, p etc. can be inside li (according to XHTML 1.0 Strict DTD from w3.org).

Don't use quotes with <<EOF:

var=$1
sudo tee "/path/to/outfile" > /dev/null <<EOF
Some text that contains my $var
EOF

Variable expansion is the default behavior inside of here-docs. You disable that behavior by quoting the label (with single or double quotes).

Use trim($source) before $s[$source].

Here's a way that will work:

export function getFunctionCallerName (){
  // gets the text between whitespace for second part of stacktrace
  return (new Error()).stack.match(/at (\S+)/g)[1].slice(3);
}

Then in your tests:

import { expect } from 'chai';
import { getFunctionCallerName } from '../../../lib/util/functions';

describe('Testing caller name', () => {

    it('should return the name of the function', () => {
      function getThisName(){
        return getFunctionCallerName();
      }

      const functionName = getThisName();

      expect(functionName).to.equal('getThisName');
    });

  it('should work with an anonymous function', () => {


    const anonymousFn = function (){
      return getFunctionCallerName();
    };

    const functionName = anonymousFn();

    expect(functionName).to.equal('anonymousFn');
  });

  it('should work with an anonymous function', () => {
    const fnName = (function (){
      return getFunctionCallerName();
    })();

    expect(/\/util\/functions\.js/.test(fnName)).to.eql(true);
  });

});

Note that the third test will only work if the test is located in /util/functions

In Excel 2010, marg's answer only worked for some of the data I had in my spreadsheet (it was imported). The following solution worked on all data.

Dim cell As range
Dim txt As String
    For Each cell In target
        txt = cell.text
        cell.NumberFormat = "@"
        cell.Value2 = txt
    Next cell

User Leigh Webber on the social.msdn.microsoft.com site posted VBA code implementing an easy-to-use clipboard interface that uses the Windows API:

http://social.msdn.microsoft.com/Forums/en/worddev/thread/ee9e0d28-0f1e-467f-8d1d-1a86b2db2878

You can get Leigh Webber's source code here

If this link doesn't go through, search for "A clipboard object for VBA" in the Office Dev Center > Microsoft Office for Developers Forums > Word for Developers section.

I created the two classes, ran his test cases, and it worked perfectly inside Outlook 2007 SP3 32-bit VBA under Windows 7 64-bit. It will most likely work for Access. Tip: To rename classes, select the class in the VBA 'Project' window, then click 'View' on the menu bar and click 'Properties Window' (or just hit F4).

With his classes, this is what it takes to copy to/from the clipboard:

Dim myClipboard As New vbaClipboard  ' Create clipboard

' Copy text to clipboard as ClipboardFormat TEXT (CF_TEXT)    
myClipboard.SetClipboardText "Text to put in clipboard", "CF_TEXT"    

' Retrieve clipboard text in CF_TEXT format (CF_TEXT = 1)
mytxt = myClipboard.GetClipboardText(1)

He also provides other functions for manipulating the clipboard.

It also overcomes 32KB MSForms_DataObject.SetText limitation - the main reason why SetText often fails. However, bear in mind that, unfortunatelly, I haven't found a reference on Microsoft recognizing this limitation.

I found useful npm package https://www.npmjs.com/package/element-resize-detector

An optimized cross-browser resize listener for elements.

Can use it with React component or functional component(Specially useful for react hooks)

You can also use inspect.getdoc. It cleans up the __doc__ by normalizing tabs to spaces and left shifting the doc body to remove common leading spaces.

Similar to other posts, but with an important distinction to make this work inside a div. The simpler answers aren't very copy-paste-able because they directly modify div or draw over the entire page.

The key here is that the containing div dividedbox has relative positioning, allowing it to sit nicely in your document with the other elements, while the quarters within have absolute positioning, giving you vertical/horizontal control inside the containing div.

As a bonus, text is responsively centered in the quarters.

HTML:

<head>
  <meta charset="utf-8">
  <title>Box model</title>
  <link rel="stylesheet" href="style.css">
</head>

<body>
  <h1 id="title">Title Bar</h1>
  <div id="dividedbox">
    <div class="quarter" id="NW">
      <p>NW</p>
    </div>
    <div class="quarter" id="NE">
      <p>NE</p>
    </div>
    <div class="quarter" id="SE">
      <p>SE</p>
    </div>?
    <div class="quarter" id="SW">
      <p>SW</p>
    </div>
  </div>
</body>

</html>

CSS:

html, body { height:95%;} /* Important to make sure your divs have room to grow in the document */
#title { background: lightgreen}
#dividedbox { position: relative; width:100%; height:95%}   /* for div growth */
.quarter {position: absolute; width:50%; height:50%;  /* gives quarters their size */
  display: flex; justify-content: center; align-items: center;} /* centers text */
#NW { top:0;    left:0;     background:orange;     }
#NE { top:0;    left:50%;   background:lightblue;  }
#SW { top:50%;  left:0;     background:green;      }
#SE { top:50%;  left:50%;   background:red;        }

PS: I've not yet used it.

To complete Sunit's answer, you can use a selector, not to the text string but to the textColorHint. You must add this attribute on your editText:

android:textColorHint="@color/text_hint_selector"

And your text_hint_selector should be:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:color="@android:color/transparent" />
    <item android:color="@color/hint_color" />
</selector>

If you want to even support for float values (Dot separated values) then you can use this expression :

var isNumber = /^\d+\.\d+$/.test(value);

You might also think about taking a different approach, and replacing the call to the network resource with a stub or mock object. Using Sinon, you can decouple the app from the network service, focusing your development efforts.

you can just do

select rownum, l.* from student  l where name like %ram%

this assigns the row number as the rows are fetched (so no guaranteed ordering of course).

if you wanted to order first do:

select rownum, l.*
  from (select * from student l where name like %ram% order by...) l;

Just regex out null bytes:

s/\x00//g;

All DECLAREs need to be at the top. ie.

delimiter //

            FETCH cur INTO m_projects_id;
            IF done THEN

If you'd like to gather more information on the error and if the error occurs in the first few iterations, I suggest you run the experiment in CPU-only mode (no GPUs). The error message will be much more specific.

When running Spring Boot + Freemarker if the page appears:

Whitelabel Error Page This application has no explicit mapping for / error, so you are seeing this as a fallback.

In spring-boot-starter-parent 2.2.1.RELEASE version freemarker does not work:

1. rename Freemarker files from .ftl to .ftlh
2. Add to application.properties: spring.freemarker.expose-request-attributes = true

spring.freemarker.suffix = .ftl

I'd just add to the answers the "why?".

. is standard member access operator that has a higher precedence than * pointer operator.

When you are trying to access a struct's internals and you wrote it as *foo.bar then the compiler would think to want a 'bar' element of 'foo' (which is an address in memory) and obviously that mere address does not have any members.

Thus you need to ask the compiler to first dereference whith (*foo) and then access the member element: (*foo).bar, which is a bit clumsy to write so the good folks have come up with a shorthand version: foo->bar which is sort of member access by pointer operator.

Take out the MONTHS from your case, and remove the brackets... like this:

CASE 
    WHEN RATE_DATE BETWEEN '2010-01-01' AND '2010-01-31' THEN 'JANUARY'
    ELSE 'NOTHING'
END AS 'MONTHS'

You can think of this as being equivalent to:

CASE TRUE
    WHEN RATE_DATE BETWEEN '2010-01-01' AND '2010-01-31' THEN 'JANUARY'
    ELSE 'NOTHING'
END AS 'MONTHS'

Try changing to this line:

PendingIntent pendingIntent = PendingIntent.getBroadcast(getContext(), 0, i, 0);

def update():
    import time
    while True:
        print 'Hello World!'
        time.sleep(5)

That'll run as a function. The while True: makes it run forever. You can always take it out of the function if you need.

You need to add @Valid to each member variable, which was also an object that contained validation constraints.

You might want to check the "X-Frame-Options" header tag. If its set to SAMEORIGIN or DENY then the iFrame insertion will be canceled by Chrome (and other browsers) per the spec.

Also, note that some browsers support the ALLOW-FROM setting but Chrome does not.

To resolve this, you will need to remove the "X-Frame-Options" header tag. This could leave you open to clickjacking attacks so you will need to decide what the risks are and how to mitigate them.

The documentation is a little light for some of the Collection methods but all the query builder aggregates are seemingly available besides avg() that can be found at http://laravel.com/docs/queries#aggregates.

no, the difference between + and \; should be reversed. + appends the files to the end of the exec command then runs the exec command and \; runs the command for each file.

The problem is find . -type f -iname '*.cpp' -exec mv {} ./test/ \+ should be find . -type f -iname '*.cpp' -exec mv {} ./test/ + no need to escape it or terminate the +

xargs I haven't used in a long time but I think works like +.

Yes it will return null if it's not present you can try this below in the demo. Both will return true. The first elements exists the second doesn't.

Demo

Html

<div id="xx"></div>

Javascript:

   if (document.getElementById('xx') !=null) 
     console.log('it exists!');

   if (document.getElementById('xxThisisNotAnElementOnThePage') ==null) 
     console.log('does not exist!');

On macOS with the default python installation you need to add /Users/<you>/Library/Python/2.7/bin/ to your $PATH.

Add this to your .bash_profile:

export PATH="/Users/<you>/Library/Python/2.7/bin:$PATH"

That's where pip installs the executables.

Tip: For non-default python version which python to find the location of your python installation and replace that portion in the path above. (Thanks for the hint Sanket_Diwale)

UPDATE: See JSFiddle

As others have mentioned, perhaps the main advantage of matrix was that it provided a convenient notation for matrix multiplication.

However, in Python 3.5 there is finally a dedicated infix operator for matrix multiplication: @.

With recent NumPy versions, it can be used with ndarrays:

A = numpy.ones((1, 3))
B = numpy.ones((3, 3))
A @ B

So nowadays, even more, when in doubt, you should stick to ndarray.

FireFox does not allow to open a local file. But if you want to use this for testing a different image (which is what I just needed to do), you can simply save the whole page locally, and then insert the url(file:///somewhere/file.png) - which works for me.

You might try this way:

fprintf('%s: (%i,%i,%i)\r\n','Answer',1,2,3)

I hope this helps.

What do you mean costs too much? Too much what?

SELECT MAX(Balance) AS MaxBalance, CustomerID FROM CUSTOMERS GROUP BY CustomerID

If your table is properly indexed (Balance) and there has got to be an index on the PK than I am not sure what you mean about costs too much or seems unreliable? There is nothing unreliable about an aggregate that you are using and telling it to do. In this case, MAX() does exactly what you tell it to do - there's nothing magical about it.

Take a look at MAX() and if you want to filter it use the HAVING clause.

t = "your string"

Play with the first N characters of a string with

def firstN(s, n=2):
    return s[:n]

which is by default equivalent to

t[:2]

A very old question I know but...

A pandas DataFrame seems to be the ideal option here.

http://pandas.pydata.org/pandas-docs/version/0.13.1/generated/pandas.DataFrame.html

From the blurb

Two-dimensional size-mutable, potentially heterogeneous tabular data structure with labeled axes (rows and columns). Arithmetic operations align on both row and column labels. Can be thought of as a dict-like container for Series objects. The primary pandas data structure

http://pandas.pydata.org/

With ES6 you can use this code :

removeDocument(doc){
   this.documents.forEach( (item, index) => {
     if(item === doc) this.documents.splice(index,1);
   });
}

    try {
        context.startActivity(FBIntent);

According to official documentation, you can set or remove the "executable" flag on any tracked file using update-index sub-command.

To set the flag, use following command:

git update-index --chmod=+x path/to/file

To remove it, use:

git update-index --chmod=-x path/to/file

Under the hood

While this looks like the regular unix files permission system, actually it is not. Git maintains a special "mode" for each file in its internal storage:

• 100644 for regular files
• 100755 for executable ones

You can visualize it using ls-file subcommand, with --stage option:

$ git ls-files --stage
100644 aee89ef43dc3b0ec6a7c6228f742377692b50484 0       .gitignore
100755 0ac339497485f7cc80d988561807906b2fd56172 0       my_executable_script.sh

By default, when you add a file to a repository, Git will try to honor its filesystem attributes and set the correct filemode accordingly. You can disable this by setting core.fileMode option to false:

git config core.fileMode false

Troubleshooting

If at some point the Git filemode is not set but the file has correct filesystem flag, try to remove mode and set it again:

git update-index --chmod=-x path/to/file
git update-index --chmod=+x path/to/file

Bonus

Starting with Git 2.9, you can stage a file AND set the flag in one command:

git add --chmod=+x path/to/file

If you'd like, you could use require. This is a way to have a conditional require statement.

let something = null;
let other = null;

if (condition) {
    something = require('something');
    other = require('something').other;
}
if (something && other) {
    something.doStuff();
    other.doOtherStuff();
}

You can simply open the phpmyadmin page from your browser, then open any existing database -> go to Privileges tab, click on your root user and then a popup window will appear, you can set your password there.. Hope this Helps.

Based off of @Mike Sherrill Cat Recall's answer, this is what worked for me:

ALTER TABLE "Children"
DROP CONSTRAINT "Children_parentId_fkey",
ADD CONSTRAINT "Children_parentId_fkey"
  FOREIGN KEY ("parentId")
  REFERENCES "Parent"(id)
  ON DELETE CASCADE;

Ref this

Method below will do all the job (memory allocation, counting the length) for you. More information and description can be found here - Implementation of Java String.split() method to split C string

int split (const char *str, char c, char ***arr)
{
    int count = 1;
    int token_len = 1;
    int i = 0;
    char *p;
    char *t;

    p = str;
    while (*p != '\0')
    {
        if (*p == c)
            count++;
        p++;
    }

    *arr = (char**) malloc(sizeof(char*) * count);
    if (*arr == NULL)
        exit(1);

    p = str;
    while (*p != '\0')
    {
        if (*p == c)
        {
            (*arr)[i] = (char*) malloc( sizeof(char) * token_len );
            if ((*arr)[i] == NULL)
                exit(1);

            token_len = 0;
            i++;
        }
        p++;
        token_len++;
    }
    (*arr)[i] = (char*) malloc( sizeof(char) * token_len );
    if ((*arr)[i] == NULL)
        exit(1);

    i = 0;
    p = str;
    t = ((*arr)[i]);
    while (*p != '\0')
    {
        if (*p != c && *p != '\0')
        {
            *t = *p;
            t++;
        }
        else
        {
            *t = '\0';
            i++;
            t = ((*arr)[i]);
        }
        p++;
    }

    return count;
}

How to use it:

int main (int argc, char ** argv)
{
    int i;
    char *s = "Hello, this is a test module for the string splitting.";
    int c = 0;
    char **arr = NULL;

    c = split(s, ' ', &arr);

    printf("found %d tokens.\n", c);

    for (i = 0; i < c; i++)
        printf("string #%d: %s\n", i, arr[i]);

    return 0;
}

You can install chrooted linux distribution alongside android bacause android is based on linux kernel. If your phone is not rooted, you may use fakeroot (easiest way is to use Debinan nonroot app) even with GUI (with android X-server app or via VNC). If you have a rooted phone, you can install almost fully functional distribution.

I think the best performance and the least limitations you can achieve with Gentoo because all software compiles to your native arm architecture and it is the most flexible, but not the easiest. You may be interested in this post about installing Gentoo on android.

Researching this topic myself and having read the answers I recommend using the path.py library since it provides a context manager for changing the current working directory.

You then have something like

import path
if path.Path('../lib').isdir():
    with path.Path('..'):
        import lib

Although, you might just omit the isdir statement.

Here I'll add print statements to make it easy to follow what's happening

import path
import pandas

print(path.Path.getcwd())
print(path.Path('../lib').isdir())
if path.Path('../lib').isdir():
    with path.Path('..'):
        print(path.Path.getcwd())
        import lib
        print('Success!')
print(path.Path.getcwd())

which outputs in this example (where lib is at /home/jovyan/shared/notebooks/by-team/data-vis/demos/lib):

/home/jovyan/shared/notebooks/by-team/data-vis/demos/custom-chart
/home/jovyan/shared/notebooks/by-team/data-vis/demos
/home/jovyan/shared/notebooks/by-team/data-vis/demos/custom-chart

Since the solution uses a context manager, you are guaranteed to go back to your previous working directory, no matter what state your kernel was in before the cell and no matter what exceptions are thrown by importing your library code.

Check out this snippet:

Private Sub openDialog()
    Dim fd As Office.FileDialog

    Set fd = Application.FileDialog(msoFileDialogFilePicker)

   With fd

      .AllowMultiSelect = False

      ' Set the title of the dialog box.
      .Title = "Please select the file."

      ' Clear out the current filters, and add our own.
      .Filters.Clear
      .Filters.Add "Excel 2003", "*.xls"
      .Filters.Add "All Files", "*.*"

      ' Show the dialog box. If the .Show method returns True, the
      ' user picked at least one file. If the .Show method returns
      ' False, the user clicked Cancel.
      If .Show = True Then
        txtFileName = .SelectedItems(1) 'replace txtFileName with your textbox

      End If
   End With
End Sub

I think this is what you are asking for.

The best solution what I know so far:

<textarea name="message" onblur="if (this.value == '') {this.value = 'text here';}"   onfocus="if (this.value == 'text here') {this.value = '';}">text here</textarea>

1. press [win] + Pause
2. Advanced settings
3. System variables
4. Append ;C:\python27\Scripts to the end of Path variable
5. Restart console

Case 1:- Let us think if migrate site from one hosting to another hosting if see this kind of issue.

Solution:- Simply go to old server copy .htaccess file code, then past in new server .htaccess file. 99% it i will works.

Write the code in your viewDidLoad()

If you use the simple for loop without the /f parameter, already renamed files will be again renamed.

I found This simpler yet powerful tutorial which uses the fileReader Object. It simply creates an img element and, using the fileReader object, assigns its source attribute as the value of the form input

function previewFile() {_x000D_
  var preview = document.querySelector('img');_x000D_
  var file    = document.querySelector('input[type=file]').files[0];_x000D_
  var reader  = new FileReader();_x000D_
_x000D_
  reader.onloadend = function () {_x000D_
    preview.src = reader.result;_x000D_
  }_x000D_
_x000D_
  if (file) {_x000D_
    reader.readAsDataURL(file);_x000D_
  } else {_x000D_
    preview.src = "";_x000D_
  }_x000D_
}

<input type="file" onchange="previewFile()"><br>_x000D_
<img src="" height="200" alt="Image preview...">

This solution is working with Android Studio 4.0.1.

Apart from creating a new module as suggested in above solution, you can try this solution.

If you have multiple modules in your application and want to add aar to just one of the module then this solution come handy.

In your root project build.gradle

add

repositories {
mavenCentral()
flatDir {
    dirs 'libs'
}

Then in the module where you want to add the .aar file locally. simply add below lines of code.

dependencies {
api fileTree(include: ['*.aar'], dir: 'libs')
implementation files('libs/<yourAarName>.aar')

}

Happy Coding :)

From the W3C FAQ:

Although many programming languages have devices like drop-down boxes that have the capability of sorting a list of items before displaying them as part of their functionality, the HTML <select> function has no such capabilities. It lists the <options> in the order received.

You'd have to sort them by hand for a static HTML document, or resort to Javascript or some other programmatic sort for a dynamic document.

In IntelliJ 2016 and newer you can change this setting from the Help menu, Edit Custom Properties (as commented by @eggplantbr).

On older versions, there's no GUI to do it. But you can change it if you edit the IntelliJ IDEA Platform Properties file:

#---------------------------------------------------------------------
# Maximum file size (kilobytes) IDE should provide code assistance for.
# The larger file is the slower its editor works and higher overall system memory requirements are
# if code assistance is enabled. Remove this property or set to very large number if you need
# code assistance for any files available regardless their size.

If you want to return a date type as just a date use

CONVERT(date, SYSDATETIME())

or

SELECT CONVERT(date,SYSDATETIME()) 

or

DECLARE @DateOnly Datetime
SET @DateOnly=CONVERT(date,SYSDATETIME())

Socket connections in Android are the same as in Java: http://www.oracle.com/technetwork/java/socket-140484.html

Things you need to be aware of:

1. If phone goes to sleep your app will no longer execute, so socket will eventually timeout. You can prevent this with wake lock. This will eat devices battery tremendously - I know I wouldn't use that app.
2. If you do this constantly, even when your app is not active, then you need to use Service.
3. Activities and Services can be killed off by OS at any time, especially if they are part of an inactive app.

Take a look at AlarmManager, if you need scheduled execution of your code.

Do you need to run your code and receive data even if user does not use the app any more (i.e. app is inactive)?

If you can convert .xls to .csv before processing, you can use the query below to import the csv to the database:

load data local infile 'FILE.CSV' into table TABLENAME fields terminated by ',' enclosed by '"' lines terminated by '\n' (FIELD1,FIELD2,FIELD3)

Set an EmptyBorder around your JPanel.
Example:

JPanel p =new JPanel();
p.setBorder(new EmptyBorder(10, 10, 10, 10));

This is just off the top of my head, but you could do an onClick event for each radio button, give them all different IDs, and then make a for loop in the event to go through each radio button in the group and find which is was checked by looking at the 'checked' attribute. The id of the checked one would be stored as a variable, but you might want to use a temp variable first to make sure that the value of that variable changed, since the click event would fire whether or not a new radio button was checked.

There are some problems when logical vector contains NA values.
See for example:

z <- c(TRUE, FALSE, NA)
sum(z) # gives you NA
table(z)["TRUE"] # gives you 1
length(z[z == TRUE]) # f3lix answer, gives you 2 (because NA indexing returns values)

So I think the safest is to use na.rm = TRUE:

sum(z, na.rm = TRUE) # best way to count TRUE values

(which gives 1). I think that table solution is less efficient (look at the code of table function).

Also, you should be careful with the "table" solution, in case there are no TRUE values in the logical vector. Suppose z <- c(NA, FALSE, NA) or simply z <- c(FALSE, FALSE), then table(z)["TRUE"] gives you NA for both cases.

Just:

foreach ( $_POST as $key => $value) {

  echo "<p>".$key."</p>";
  echo "<p>".$value."</p>";
  echo "<hr />";

} 

If you don't need it to be human-readable/editable, the easiest solution is to just use pickle.

To write:

with open(the_filename, 'wb') as f:
    pickle.dump(my_list, f)

To read:

with open(the_filename, 'rb') as f:
    my_list = pickle.load(f)

If you do need them to be human-readable, we need more information.

If my_list is guaranteed to be a list of strings with no embedded newlines, just write them one per line:

with open(the_filename, 'w') as f:
    for s in my_list:
        f.write(s + '\n')

with open(the_filename, 'r') as f:
    my_list = [line.rstrip('\n') for line in f]

If they're Unicode strings rather than byte strings, you'll want to encode them. (Or, worse, if they're byte strings, but not necessarily in the same encoding as your system default.)

If they might have newlines, or non-printable characters, etc., you can use escaping or quoting. Python has a variety of different kinds of escaping built into the stdlib.

Let's use unicode-escape here to solve both of the above problems at once:

with open(the_filename, 'w') as f:
    for s in my_list:
        f.write((s + u'\n').encode('unicode-escape'))

with open(the_filename, 'r') as f:
    my_list = [line.decode('unicode-escape').rstrip(u'\n') for line in f]

You can also use the 3.x-style solution in 2.x, with either the codecs module or the io module:*

import io

with io.open(the_filename, 'w', encoding='unicode-escape') as f:
    f.writelines(line + u'\n' for line in my_list)

with open(the_filename, 'r') as f:
    my_list = [line.rstrip(u'\n') for line in f]

_{* TOOWTDI, so which is the one obvious way? It depends… For the short version: if you need to work with Python versions before 2.6, use codecs; if not, use io.}

From my code, comparing to above solution, the simplest way is to define a layout which contains the fragment, then you could hide or unhide the fragment by controlling the layout attribute which is align with the general way of view. No additional code needed in this case and the additional deployment attributes of the fragment could be moved to the outer layout.

<LinearLayout style="@style/StHorizontalLinearView"
    >

    <fragment
        android:layout_width="match_parent"
        android:layout_height="390dp"
        android:layout_alignParentTop="true"
        />

</LinearLayout>

Construct a List<AppMeta> from the excluded List and use the Except Linq operator.

var ex = excludedAppIds.Select(x => new AppMeta{Id = x}).ToList();                           
var result = ex.Except(unfilteredApps).ToList();

I think why you want to zoom-in and zoom-out the image view is because your image view is small and zooming in the image there will not let the image come out of the image view. Instead, image starts disappearing from the boundaries while zooming in. So letting the image come out of the image while we zoom in is what you want I guess.

So there are two tricks (according to me) to achieve this-

1. Change the layout params of the image view to cover the whole outermost view or view group at runtime while we are about to zoom-in the image.
2. Make an expanded Image view or Full Image View (height and width = Outermost View or View Group) in xml file and set it's visibility to gone. When we are about to zoom-in the image, load the image from small Image View into full Img View, map the image in fullImgView to image in smallImgView and make it's view visible.

Trick no.1 does not work when the image View is nested very much inside other views (like in nested recycler view)

Trick no.2 works always :-)

Here is the implementation of trick no.2 -

public class ZoomOnTouchListener extends AppCompatActivity implements View.OnTouchListener {

    private Matrix matrix = new Matrix();

    private boolean isfullImgViewActive = false;
    // above boolean gets true when when we firstly move 2 fingers on the smallImgView and in this case smallImgView gets invisible and fullImgView gets visible
    // and false if smallImgView is visible and fullImgView is gone

    private PointF prevP1 = new PointF();

        mfullImgView.setVisibility(View.GONE);
        smallImgView = (ImageView)findViewById(R.id.imgView);
        smallImgView.setOnTouchListener(this);    

    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        //Log.i("0", "OnTouch()");
        if(v instanceof ImageView) {
            ImageView imgView = (ImageView) v;

                            matrix.set(imgView.getImageMatrix());   //note:- do not write matrix = imgView.getImageMatrix() because it gives the smallImgView's matrix reference to the matrix variable and changes on matrix will reflect on smallImgView

        return (float) Math.sqrt(x * x + y * y);
    }


    private void midPoint(PointF point, MotionEvent event)
    {
        float x = event.getX(0) + event.getX(1);
        float y = event.getY(0) + event.getY(1);
        point.set(x / 2, y / 2);
    }

}

NOTE:- Don't set OnClickListener to mfullImgView before setting onTouchListener to it. Setting that will let the fullImageView(if it is visible) steal the touch event of putting second finger down after lifting it for the first time because we want to let the smallImgView take all the touch events until all the fingers are lifted up for the first time.

You can use the spread operator to convert Map.keys() iterator in an Array.

let myMap = new Map().set('a', 1).set('b', 2).set(983, true)_x000D_
let keys = [...myMap.keys()]_x000D_
console.log(keys)

I was getting the error “gcc: error: x86_64-linux-gnu-gcc: No such file or directory” as I was trying to build a simple c-extension module to run in Python. I tried all the things above to no avail, and finally realized that I had an error in my module.c code! So I thought it would be helpful to add that, if you are getting this error message but you have python-dev and everything correctly installed, you should look for issues in your code.

Have a look at Select2 for Bootstrap. It should be able to do everything you need.

Another good option is Selectize.js. It feels a bit more native to Bootstrap.

I'm answering only the part of the question about zbar installation.

I spent nearly half an hour a few hours to make it work on Windows + Python 2.7 64-bit, so here are additional notes to the accepted answer:

• Download https://github.com/NaturalHistoryMuseum/ZBarWin64/releases/download/v0.10/zbar-0.10-cp27-none-win_amd64.whl

• Install it with pip install zbar-0.10-cp27-none-win_amd64.whl

• If Python reports an ImportError: DLL load failed: The specified module could not be found. when doing import zbar, then you will just need to install the Visual C++ Redistributable Packages for VS 2013 (I spent a lot of time here, trying to recompile unsuccessfully...)

• Required too: libzbar64-0.dll must be in a folder which is in the PATH. In my case I copied it to "C:\Python27\libzbar64-0.dll" (which is in the PATH). If it still does not work, add this:

  import os
  os.environ['PATH'] += ';C:\\Python27' 
  import zbar
  

PS: Making it work with Python 3.x is even more difficult: Compile zbar for Python 3.x.

PS2: I just tested pyzbar with pip install pyzbar and it's MUCH easier, it works out-of-the-box (the only thing is you need to have VC Redist 2013 files installed). It is also recommended to use this library in this pyimagesearch.com article.

There's no easy answer, because Object — which every object in JavaScript derives from — includes many attributes automatically, and the exact set of attributes you get depends on the particular interpreter and what code has executed before yours. So, you somehow have to separate the ones you defined from those you got "for free."

Here's one way:

var foo = {"key1": "value1", "key2": "value2", "key3": "value3"};
Object.prototype.foobie = 'bletch'; // add property to foo that won't be counted

var count = 0;
for (var k in foo) {
    if (foo.hasOwnProperty(k)) {
       ++count;
    }
}
alert("Found " + count + " properties specific to foo");

The second line shows how other code can add properties to all Object derivatives. If you remove the hasOwnProperty() check inside the loop, the property count will go up to at least 4. On a page with other JavaScript besides this code, it could be higher than 4, if that other code also modifies the Object prototype.

You can add style to your text:

  style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); 
    text-shadow: rgb(255, 255, 255) -2px -2px 0px, rgb(255, 255, 255) -2px 2px 0px, 
     rgb(255, 255, 255) 2px -2px 0px, rgb(255, 255, 255) 2px 2px 0px;"

White, in this example. Does not work in IE :)

You can set the cookie after having checked if it exists with a value.

 $(document).ready(function(){            
      if ($.cookie('cookie')) { //if cookie isset
         //do stuff here like hide a popup when cookie isset
         //document.getElementById("hideElement").style.display = "none";
      }else{
         var CookieSet = $.cookie('cookie', 'value'); //set cookie
      }       
 });

Now, you don't need to use FormBuilder and all this complicated valiation angular stuff. I put more details from this (Angular 2.0.8 - 3march2016): https://github.com/angular/angular/commit/38cb526

Example from repo :

<input [ngControl]="fullName" pattern="[a-zA-Z ]*">

I test it and it works :) - here is my code:

<form (ngSubmit)="onSubmit(room)" #roomForm='ngForm'  >
...
<input 
  id='room-capacity' 
  type="text" 
  class="form-control" 
  [(ngModel)]='room.capacity' 
  ngControl="capacity" 
  required
  pattern="[0-9]+" 
  #capacity='ngForm'>

Alternative approach (UPDATE June 2017)

Validation is ONLY on server side. If something is wrong then server return error code e.g HTTP 400 and following json object in response body (as example):

this.err = { 
    "capacity" : "too_small"
    "filed_name" : "error_name", 
    "field2_name" : "other_error_name",
    ... 
}

In html template I use separate tag (div/span/small etc.)

<input [(ngModel)]='room.capacity' ...>
<small *ngIf="err.capacity" ...>{{ translate(err.capacity) }}</small>

If in 'capacity' is error then tag with msg translation will be visible. This approach have following advantages:

• it is very simple
• avoid backend validation code duplication on frontend (for regexp validation this can either prevent or complicate ReDoS attacks)
• control on way the error is shown (e.g. <small> tag)
• backend return error_name which is easy to translate to proper language in frontend

Of course sometimes I make exception if validation is needed on frontend side (e.g. retypePassword field on registration is never send to server).

I used the following code, it's working!

Let's take a moment to understand the problem before blindly charging in to attempt to fix it.

A quick poke around in the debugger will tell you that separator lines are subviews of UITableViewCell. It seems that the cell itself takes a fair amount of responsibility for the layout of these lines.

iOS 8 introduces the concept of layout margins. By default, a view's layout margins are 8pt on all sides, and they're inherited from ancestor views.

As best we can tell, when laying out out its separator line, UITableViewCell chooses to respect the left-hand layout margin, using it to constrain the left inset.

Putting all that together, to achieve the desired inset of truly zero, we need to:

• Set the left layout margin to 0
• Stop any inherited margins overriding that

Put like that, it's a pretty simple task to achieve:

cell.layoutMargins = UIEdgeInsetsZero;
cell.preservesSuperviewLayoutMargins = NO;

Things to note:

• This code only needs to be run once per cell (you're just configuring the cell's properties after all), and there's nothing special about when you choose to execute it. Do what seems cleanest to you.
• Sadly neither property is available to configure in Interface Builder, but you can specify a user-defined runtime attribute for preservesSuperviewLayoutMargins if desired.
• Clearly, if your app targets earlier OS releases too, you'll need to avoid executing the above code until running on iOS 8 and above.
• Rather than setting preservesSuperviewLayoutMargins, you can configure ancestor views (such as the table) to have 0 left margin too, but this seems inherently more error-prone as you don't control that entire hierarchy.
• It would probably be slightly cleaner to set only the left margin to 0 and leave the others be.
• If you want to have a 0 inset on the "extra" separators that UITableView draws at the bottom of plain style tables, I'm guessing that will require specifying the same settings at the table level too (haven't tried this one!)

Method 1

Word boundaries would work perfectly here, such as with:

\b\w{3,8}\b
\b\w{2,}
\b\w{,10}\b
\b\w{5}\b

RegEx Demo 1

Java

Some languages such as Java and C++ are double-escape required:

\\b\\w{3,8}\\b
\\b\\w{2,}
\\b\\w{,10}\\b
\\b\\w{5}\\b

^{PS: \\b\\w{,10}\\b may not work for all languages or flavors.}

Test 1

import java.util.regex.Matcher;
import java.util.regex.Pattern;


public class RegularExpression{

    public static void main(String[] args){


        final String regex = "\\b\\w{3,8}\\b";
        final String string = "words with length three to eight";

        final Pattern pattern = Pattern.compile(regex, Pattern.MULTILINE);
        final Matcher matcher = pattern.matcher(string);

        while (matcher.find()) {
            System.out.println("Full match: " + matcher.group(0));
        }

    }
}

Output 1

Full match: words
Full match: with
Full match: length
Full match: three
Full match: eight

Method 2

Another good-to-know method is to use negative lookarounds:

(?<!\w)\w{3,8}(?!\w)
(?<!\w)\w{2,}
(?<!\w)\w{,10}(?!\w)
(?<!\w)\w{5}(?!\w)

Java

(?<!\\w)\\w{3,8}(?!\\w)
(?<!\\w)\\w{2,}
(?<!\\w)\\w{,10}(?!\\w)
(?<!\\w)\\w{5}(?!\\w)

RegEx Demo 2

Test 2

import java.util.regex.Matcher;
import java.util.regex.Pattern;


public class RegularExpression{

    public static void main(String[] args){


        final String regex = "(?<!\\w)\\w{1,10}(?!\\w)";
        final String string = "words with length three to eight";

        final Pattern pattern = Pattern.compile(regex, Pattern.MULTILINE);
        final Matcher matcher = pattern.matcher(string);

        while (matcher.find()) {
            System.out.println("Full match: " + matcher.group(0));
        }

    }
}

Output 2

Full match: words
Full match: with
Full match: length
Full match: three
Full match: to
Full match: eight

RegEx Circuit

jex.im visualizes regular expressions:

If you wish to simplify/modify/explore the expression, it's been explained on the top right panel of regex101.com. If you'd like, you can also watch in this link, how it would match against some sample inputs.

We can use another way as well for example to insert the value with special characters 'Java_22 & Oracle_14' into db we can use the following format..

'Java_22 '||'&'||' Oracle_14'

Though it consider as 3 different tokens we dont have any option as the handling of escape sequence provided in the oracle documentation is incorrect.

Just in case you don't want to bump Windows SDK to Windows 10 (you could be for example working on an open source project where the decision isn't yours to make), you can solve this problem in a Windows SDK 8.1 project by navigating Tools -> Get Tools and Features... -> Individual Compontents tab and installing the individual components "Windows 8.1 SDK" (under SDKs, libraries and frameworks) and "Windows Universal CRT SDK" (under Compilers, build tools and runtimes):

session.query().with_entities(SomeModel.col1)

is the same as

session.query(SomeModel.col1)

for alias, we can use .label()

session.query(SomeModel.col1.label('some alias name'))

<input id="date" name="date" />
<script type="text/javascript">
document.getElementById("date").value = new Date();
</script>

Of course that works; when @item1 = N'', it IS NOT NULL.

You can define @item1 as NULL by default at the top of your stored procedure, and then not pass in a parameter.

Actually, there are two ways to include images in email.

The first way ensures that the user will see the image, even if in some cases it’s only as an attachment to the message. This method is exactly what we call as “embedding images in email" in daily life.
Essentially, you’re attaching the image to the email. The plus side is that, in one way or another, the user is sure to get the image. While the downside is two fold. Firstly, spam filters look for large, embedded images and often give you a higher spam score for embedding images in email (Lots of spammers use images to avoid having the inappropriate content in their emails read by the spam filters.). Secondly, if you pay to send your email by weight or kilobyte, this increases the size of your message. If you’re not careful, it can even make your message too big for the parameters of the email provider.

The second way to include images (and the far more common way) is the same way that you put an image on a web page. Within the email, you provide a url that is the reference to the image’s location on your server, exactly the same way that you would on a web page. This has several benefits. Firstly, you won’t get caught for spamming or for your message “weighing” too much because of the image. Secondly, you can make changes to the images after the email has been sent if you find errors in them. On the flip side, your recipient will need to actively turn on image viewing in their email client to see your images.

The answer is already posted but note that this will pass the ArrayList by reference. So if you make any changes to the list in the function it will be affected to the original list also.

<access-modfier> <returnType> AnalyseArray(ArrayList<Integer> list)
{
//analyse the list
//return value
}

call it like this:

x=AnalyseArray(list);

or pass a copy of ArrayList:

x=AnalyseArray(list.clone());

Generate the scripts?

Generate a script to create the table then generate a script to insert the data.

check-out SP_ Genereate_Inserts for generating the data insert script.

I had the same problem on windows "error: failed to execute prompt script (exit code 1) fatal: could not read Username for 'https://github.com': No error" trying to login to github through the login dialog. When I canceled the dialog git asked me for login and password in the command line and it worked fine.

:) Your using the thread in a wrong way. Just do the following:

private void runthread()
{

splashTread = new Thread() {
            @Override
            public void run() {
                try {
                    synchronized(this){

                        //wait 5 sec
                        wait(_splashTime);
                    }

                } catch(InterruptedException e) {}
                finally {
                    //call the handler to set the text
                }
            }
        };

        splashTread.start(); 
}

That's it.

You have to be careful, server responses in the range of 4xx and 5xx throw a WebException. You need to catch it, and then get status code from a WebException object:

try
{
    wResp = (HttpWebResponse)wReq.GetResponse();
    wRespStatusCode = wResp.StatusCode;
}
catch (WebException we)
{
    wRespStatusCode = ((HttpWebResponse)we.Response).StatusCode;
}

A possibility is that the git server you are pushing to is down/crashed, and the solution lies in restarting the git server.

T must be defined within the scope in which you are working. Therefore, what you have posted will work if your class is generic on T:

public class MyClass<T>
{
    private List<T> newList;

    public List<T> NewList
    {
        get{return newList;}
        set{newList = value;}
    }
}

Otherwise, you have to use a defined type.

EDIT: Per @lKashef's request, following is how to have a List property:

private List<int> newList;

public List<int> NewList
{
    get{return newList;}
    set{newList = value;}
}

This can go within a non-generic class.

Edit 2: In response to your second question (in your edit), I would not recommend using a list for this type of data handling (if I am understanding you correctly). I would put the user settings in their own class (or struct, if you wish) and have a property of this type on your original class:

public class UserSettings
{
 string FirstName { get; set; }
 string LastName { get; set; }
 // etc.
}

public class MyClass
{
 string MyClassProperty1 { get; set; }
 // etc.

 UserSettings MySettings { get; set; }
}

This way, you have named properties that you can reference instead of an arbitrary index in a list. For example, you can reference MySettings.FirstName as opposed to MySettingsList[0].

Let me know if you have any further questions.

EDIT 3: For the question in the comments, your property would be like this:

public class MyClass
{
    public List<KeyValuePair<string, string>> MySettings { get; set; } 
}

EDIT 4: Based on the question's edit 2, following is how I would use this:

public class MyClass
{
    // note that this type of property declaration is called an "Automatic Property" and
    // it means the same thing as you had written (the private backing variable is used behind the scenes, but you don't see it)
    public List<KeyValuePair<string, string> MySettings { get; set; } 
}

public class MyConsumingClass
{
    public void MyMethod
    {
        MyClass myClass = new MyClass();
        myClass.MySettings = new List<KeyValuePair<string, string>>();
        myClass.MySettings.Add(new KeyValuePair<string, string>("SomeKeyValue", "SomeValue"));

        // etc.
    }
}

You mentioned that "the property still won't appear in the object's instance," and I am not sure what you mean. Does this property not appear in IntelliSense? Are you sure that you have created an instance of MyClass (like myClass.MySettings above), or are you trying to access it like a static property (like MyClass.MySettings)?

In our case what caused the issue is that the private key we were trying to use was encrypted with a passphrase.

We had to decrypt the private key using ssh-keygen -p before we could use the private key with the openssl command line tool.

for ((i=0; i<=1000; i++)); do
    echo "http://example.com/$i.jpg"
done

def convertSeconds(seconds):
    h = seconds//(60*60)
    m = (seconds-h*60*60)//60
    s = seconds-(h*60*60)-(m*60)
    return [h, m, s]

The function input is a number of seconds, and the return is a list of hours, minutes and seconds which that amount of seconds represent.

Some reading to get you started on character encodings: Joel on Software: The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)

By the way - ASP.NET has nothing to do with it. Encodings are universal.

If you want JUST the source, and not an array with other information:

<?php $url = wp_get_attachment_url( get_post_thumbnail_id($post->ID), 'thumbnail' ); ?>
<img src="<?php echo $url ?>" />

I you want to preview the rows you are about to remove and keep control over which of the duplicate rows to keep. See http://developer.azurewebsites.net/2014/09/better-sql-group-by-find-duplicate-data/

with MYCTE as (
  SELECT ROW_NUMBER() OVER (
    PARTITION BY DuplicateKey1
                ,DuplicateKey2 -- optional
    ORDER BY CreatedAt -- the first row among duplicates will be kept, other rows will be removed
  ) RN
  FROM MyTable
)
DELETE FROM MYCTE
WHERE RN > 1

Google basis (free) does not provide address verification (Geocoding) as there is no UK postcode license.

This means postcode searches are very in-accurate. The proximity search is very poor, even for town searches, often not recognising locations.

This is why Google have a premier and a enterprise solution which still is more expensive and not as good as business mapping specialists like bIng and Via Michelin who also have API's.

As a free lance developer, so serious business would use Google as the system is weak and really provides a watered down solution.

It's not possible with CSS3. There is a proposed CSS4 selector, $, to do just that, which could look like this (Selecting the li element):

ul $li ul.sub { ... }

See the list of CSS4 Selectors here.

As an alternative, with jQuery, a one-liner you could make use of would be this:

$('ul li:has(ul.sub)').addClass('has_sub');

You could then go ahead and style the li.has_sub in your CSS.

You might have python 3 pip installed already. Instead of pip install you can use pip3 install.

You can use PreferredSize and flexibleSpace for it:

appBar: PreferredSize(
  preferredSize: Size.fromHeight(100.0),
  child: AppBar(
    automaticallyImplyLeading: false, // hides leading widget
    flexibleSpace: SomeWidget(),
  )
),

This way you can keep the elevation of AppBar for keeping its shadow visible and have custom height, which is what I was just looking for. You do have to set the spacing in SomeWidget, though.

I suspect because of modules, which remove the need for the #import <Cocoa/Cocoa.h>.

As to where to put code that you would put in a prefix header, there is no code you should put in a prefix header. Put your imports into the files that need them. Put your definitions into their own files. Put your macros...nowhere. Stop writing macros unless there is no other way (such as when you need __FILE__). If you do need macros, put them in a header and include it.

The prefix header was necessary for things that are huge and used by nearly everything in the whole system (like Foundation.h). If you have something that huge and ubiquitous, you should rethink your architecture. Prefix headers make code reuse hard, and introduce subtle build problems if any of the files listed can change. Avoid them until you have a serious build time problem that you can demonstrate is dramatically improved with a prefix header.

In that case you can create one and pass it into clang, but it's incredibly rare that it's a good idea.

EDIT: To your specific question about a HUD you use in all your view controllers, yes, you should absolutely import it into every view controller that actually uses it. This makes the dependencies clear. When you reuse your view controller in a new project (which is common if you build your controllers well), you will immediately know what it requires. This is especially important for categories, which can make code very hard to reuse if they're implicit.

The PCH file isn't there to get rid of listing dependencies. You should still import UIKit.h or Foundation.h as needed, as the Xcode templates do. The reason for the PCH is to improve build times when dealing with really massive headers (like in UIKit).

Yet another option is to have, in Ticket, one column specifying the owning entity type (User or Group), second column with referenced User or Group id and NOT to use Foreign Keys but instead rely on a Trigger to enforce referential integrity.

Two advantages I see here over Nathan's excellent model (above):

• More immediate clarity and simplicity.
• Simpler queries to write.

you can try this without any java script you can do that just by using CSS

img:active,
img:focus,
img:hover{ 
border: 10px solid red !important
}

of if your case is to add any other css class by clicking you can use query selector like

<img id="image1" ng-click="changeClass(id)" >
<img id="image2" ng-click="changeClass(id)" >
<img id="image3" ng-click="changeClass(id)" >
<img id="image3" ng-click="changeClass(id)" >

in controller first search for any image with red border and remove it then by passing the image id add the border class to that image

$scope.changeClass = function(id){
angular.element(document.querySelector('.some-class').removeClass('.some-class');
angular.element(document.querySelector(id)).addClass('.some-class');
}

From the man read:

#include <unistd.h>
ssize_t read(int fd, void *buf, size_t count);

Input parameters:

• int fd file descriptor is an integer and not a file pointer. The file descriptor for stdin is 0

• void *buf pointer to buffer to store characters read by the read function

• size_t count maximum number of characters to read

So you can read character by character with the following code:

char buf[1];

while(read(0, buf, sizeof(buf))>0) {
   // read() here read from stdin charachter by character
   // the buf[0] contains the character got by read()
   ....
}

Solution with LOCALE_ID is great if you want to set the language for your app once. But it doesn’t work, if you want to change the language during runtime. For this case you can implement custom date pipe.

import { DatePipe } from '@angular/common';
import { Pipe, PipeTransform } from '@angular/core';
import { TranslateService } from '@ngx-translate/core';

@Pipe({
  name: 'localizedDate',
  pure: false
})
export class LocalizedDatePipe implements PipeTransform {

  constructor(private translateService: TranslateService) {
  }

  transform(value: any, pattern: string = 'mediumDate'): any {
    const datePipe: DatePipe = new DatePipe(this.translateService.currentLang);
    return datePipe.transform(value, pattern);
  }

}

Now if you change the app display language using TranslateService (see ngx-translate)

this.translateService.use('en');

the formats within your app should automatically being updated.

Example of use:

<p>{{ 'note.created-at' | translate:{date: note.createdAt | localizedDate} }}</p>
<p>{{ 'note.updated-at' | translate:{date: note.updatedAt | localizedDate:'fullDate'} }}</p>

or check my simple "Notes" project here.

If you are using Kotlin and Kotlin android extensions, then there is a beautiful way of doing this.

val uri = myUriString.toUri()

To add Kotlin extensions (KTX) to your project add the following to your app module's build.gradle

  repositories {
    google()
}

dependencies {
    implementation 'androidx.core:core-ktx:1.0.0-rc01'
}

I had been having issues where I was using

overflow: none;

But I knew CSS didn't really like it and it didn’t work 100% for how I wanted it to.

However, this is a perfect solution as none of my content is supposed to be larger than intended and this has fixed the issue I had.

overflow: auto;

I think you shouldn't prepend themesDir. You only pass the filename of the template to flask, it will then look in a folder called templates relative to your python file.

Please try this one and I guarantee that it will work

  <script type="text/javascript">
  function blink() {
  var blinks = document.getElementsByTagName('blink');
  for (var i = blinks.length - 1; i >= 0; i--) {
  var s = blinks[i];
  s.style.visibility = (s.style.visibility === 'visible') ? 'hidden' : 'visible';
}
window.setTimeout(blink, 1000);
}
if (document.addEventListener) document.addEventListener("DOMContentLoaded", blink, false);
else if (window.addEventListener) window.addEventListener("load", blink, false);
else if (window.attachEvent) window.attachEvent("onload", blink);
else window.onload = blink;

Then put this below:

<blink><center> Your text here </blink></div>

Came across this question looking for access to column names on Teradata, so I'll add the answer for their 'flavour' of SQL:

SELECT ColumnName
FROM DBC.Columns
WHERE DatabaseName='DBASE_NAME'
AND TableName='TABLE_NAME';

The info is stored in the DBC dbase.

Getting data types is a little bit more involved: Get column type using teradata system tables

If using a StackTraceElement, use:

String fullClassName = stackTraceElement.getClassName();
String simpleClassName = fullClassName.substring(fullClassName.lastIndexOf('.') + 1);

System.out.println(simpleClassName);

Data List is a new HTML tag in HTML5 supported browsers. It renders as a text box with some list of options. For Example for Gender Text box it will give you options as Male Female when you type 'M' or 'F' in Text Box.

<input list="Gender">
<datalist id="Gender">
  <option value="Male">
  <option value="Female> 
</datalist>

Firebase Remote Config could be a possible and reliable solution for now, since google didn't expose any api to it.

Check Firebase Remote Config Docs

Steps 1.Create a firebase project and add google_play_service.json to your project

2.Create keys like "android_latest_version_code" and "android_latest_version_name" in firebase console->Remote Config

3.Android Code

    public void initializeFirebase() {
        if (FirebaseApp.getApps(mContext).isEmpty()) {
            FirebaseApp.initializeApp(mContext, FirebaseOptions.fromResource(mContext));
        }
        final FirebaseRemoteConfig config = FirebaseRemoteConfig.getInstance();
        FirebaseRemoteConfigSettings configSettings = new FirebaseRemoteConfigSettings.Builder()
                                                              .setDeveloperModeEnabled(BuildConfig.DEBUG)
                                                              .build();
        config.setConfigSettings(configSettings);
}

Get current version name and code

int playStoreVersionCode = FirebaseRemoteConfig.getInstance().getString(
                "android_latest_version_code");
PackageInfo pInfo = this.getPackageManager().getPackageInfo(getPackageName(), 0);
int currentAppVersionCode = pInfo.versionCode; 
if(playStoreVersionCode>currentAppVersionCode){
//Show update popup or whatever best for you
}

4. And keep firebase "android_latest_version_code" and "android_latest_version_name" upto date with your current production version name and code.

Firebase remote config works on both Android and IPhone.

Best thing is to memorize balance equation in natural way.

Amount / Whole = Percentage / 100

usually You have one variable missing, in this case it is Amount

Amount / 10000 = 35.8 / 100

then you have high school math (proportion) to multiple outer from both sides and inner from both sides.

Amount * 100 = 358 000

Amount = 3580

It works the same in all languages and on paper. JavaScript is no exception.

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
}

If you add your site to "Local Intranet" in

Chrome > Options > Under the Hood > Change Proxy Settings > Security (tab) > Local Intranet/Sites > Advanced.

Add you site URL here and it will work.

Update for New Version of Chrome

Chrome > Settings > Advanced > System > Open Proxy Settings > Security (tab) > Local Intranet > Sites (button) > Advanced.

You can also use template reference variables

<form (submit)="onSubmit(player.value)">
   <input #player placeholder="player name">
</form>

onSubmit(playerName: string) {
  console.log(playerName)
}

Your selector for the .show() and .hide() are not pointing to anything in the code.

You could try to open it for write, and if successful then you could assume the other application is done with the file.

private void OnChanged(object source, FileSystemEventArgs e)
{
    try
    {
        using (var fs = File.OpenWrite(e.FullPath))
        {
        }
        //do your stuff
    }
    catch (Exception)
    {
        //no write access, other app not done
    }
}

Just opening it for write appears not to raise the changed event. So it should be safe.

Let's say we have the following Spark DataFrame:

        (3, "Joshua", "Peterson")
    ], 
    ('id', 'firstName', 'lastName')
)

There are typically three different ways you can use to print the content of the dataframe:

Print Spark DataFrame

The most common way is to use show() function:

>>> df.show()
+---+---------+--------+
| id|firstName|lastName|
+---+---------+--------+
|  1|     Mark|   Brown|
|  2|      Tom|Anderson|
|  3|   Joshua|Peterson|
+---+---------+--------+

Print Spark DataFrame vertically

Say that you have a fairly large number of columns and your dataframe doesn't fit in the screen. You can print the rows vertically - For example, the following command will print the top two rows, vertically, without any truncation.

>>> df.show(n=2, truncate=False, vertical=True)
-RECORD 0-------------
 id        | 1        
 firstName | Mark     
 lastName  | Brown    
-RECORD 1-------------
 id        | 2        
 firstName | Tom      
 lastName  | Anderson 
only showing top 2 rows

Convert to Pandas and print Pandas DataFrame

Alternatively, you can convert your Spark DataFrame into a Pandas DataFrame using .toPandas() and finally print() it.

>>> df_pd = df.toPandas()
>>> print(df_pd)
   id firstName  lastName
0   1      Mark     Brown
1   2       Tom  Anderson
2   3    Joshua  Peterson

Note that this is not recommended when you have to deal with fairly large dataframes, as Pandas needs to load all the data into memory. If this is the case, the following configuration will help when converting a large spark dataframe to a pandas one:

spark.conf.set("spark.sql.execution.arrow.pyspark.enabled", "true")

For more details you can refer to my blog post Speeding up the conversion between PySpark and Pandas DataFrames

Also, make sure you have no files that accidentally try to inherit or define the same (partial) class as other files. Note that these files can seem unrelated to the files where the error actually appeared!

None of these worked for me.

My class libraries were definitely all referencing both System.Core and Microsoft.CSharp. Web Application was 4.0 and couldn't upgrade to 4.5 due to support issues.

I was encountering the error compiling a razor template using the Razor Engine, and only encountering it intermittently, like after web application has been restarted.

The solution that worked for me was manually loading the assembly then reattempting the same operation...

        bool retry = true;
        while (retry)
        {
            try
            {
                string textTemplate = File.ReadAllText(templatePath);
                Razor.CompileWithAnonymous(textTemplate, templateFileName);
                retry = false;
            }
            catch (TemplateCompilationException ex)
            {
                LogTemplateException(templatePath, ex);
                retry = false;

                if (ex.Errors.Any(e  => e.ErrorNumber == "CS1969"))
                {
                    try
                    {
                        _logger.InfoFormat("Attempting to manually load the Microsoft.CSharp.RuntimeBinder.Binder");
                        Assembly csharp = Assembly.Load("Microsoft.CSharp, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a");
                        Type type = csharp.GetType("Microsoft.CSharp.RuntimeBinder.Binder");
                        retry = true;
                    }
                    catch(Exception exLoad)
                    {
                        _logger.Error("Failed to manually load runtime binder", exLoad);
                    }
                }

                if (!retry)
                    throw;
            }
        }

Hopefully this might help someone else out there.

A couple of "enhancements" I use for debugging, especially when running projects (ie not in debug mode).

1. Default the message-box title to the name of the calling method. This is handy for stopping a thread at a given point, but must be cleaned-up before release.

2. Automatically copy the caller-name and message to the clipboard, because you can't search an image!

   package forumposts;
   
   import java.awt.Toolkit;
   import java.awt.datatransfer.Clipboard;
   import java.awt.datatransfer.StringSelection;
   import javax.swing.JOptionPane;
   
   public final class MsgBox
   {
       public static void info(String message) {
           info(message, theNameOfTheMethodThatCalledMe());
       }
       public static void info(String message, String caller) {
           show(message, caller, JOptionPane.INFORMATION_MESSAGE);
       }
   
       static void error(String message) {
           error(message, theNameOfTheMethodThatCalledMe());
       }
       public static void error(String message, String caller) {
           show(message, caller, JOptionPane.ERROR_MESSAGE);
       }
   
       public static void show(String message, String title, int iconId) {
           setClipboard(title+":"+NEW_LINE+message);
           JOptionPane.showMessageDialog(null, message, title, iconId);
       }
       private static final String NEW_LINE = System.lineSeparator();
   
       public static String theNameOfTheMethodThatCalledMe() {
           return Thread.currentThread().getStackTrace()[3].getMethodName();
       }
   
       public static void setClipboard(String message) {
           CLIPBOARD.setContents(new StringSelection(message), null);
           // nb: we don't respond to the "your content was splattered"
           //     event, so it's OK to pass a null owner.
       }
       private static final Toolkit AWT_TOOLKIT = Toolkit.getDefaultToolkit();
       private static final Clipboard CLIPBOARD = AWT_TOOLKIT.getSystemClipboard();
   
   }
   

The full class also has debug and warning methods, but I cut them for brevity and you get the main points anyway. You can use a public static boolean isDebugEnabled to suppress debug messages. If done properly the optimizer will (almost) remove these method calls from your production code. See: http://c2.com/cgi/wiki?ConditionalCompilationInJava

There's an example of how to use Font Awesome alongside an unordered list on their examples page.

<ul class="icons">
  <li><i class="icon-ok"></i> Lists</li>
  <li><i class="icon-ok"></i> Buttons</li>
  <li><i class="icon-ok"></i> Button groups</li>
  <li><i class="icon-ok"></i> Navigation</li>
  <li><i class="icon-ok"></i> Prepended form inputs</li>
</ul>

If you can't find it working after trying this code then you're not including the library correctly. According to their website, you should include the libraries as such:

<link rel="stylesheet" href="../css/bootstrap.css">
<link rel="stylesheet" href="../css/font-awesome.css">

Also check out the whimsical Chris Coyier's post on icon fonts on his website CSS Tricks.

Here's a screencast by him as well talking about how to create your own icon font-face.

this native-base there is solution:

<Button
    block
    disabled={!learnedWordsByUser.length}
    style={{ marginTop: 10 }}
    onPress={learnedWordsByUser.length && () => {
      onFlipCardsGenerateNewWords(learnedWordsByUser)
      onFlipCardsBtnPress()
    }}
>
    <Text>Let's Review</Text>
</Button>

Changing from PuTTY to OpenSSH fixed this issue for me, without needing to unset GIT_SSH, etc.

The only exact solution is to perform arbitrary-precision decimal arithmetic for the base conversion, since the exact value can be very long - for 80-bit long double, up to about 10000 decimal places. Fortunately it's "only" up to about 700 places or so for IEEE double.

Rather than working with individual decimal digits, it's helpful to instead work base-1-billion (the highest power of 10 that fits in a 32-bit integer) and then convert these "base-1-billion digits" to 9 decimal digits each at the end of your computation.

I have a very dense (rather hard to read) but efficient implementation here, under LGPL MIT license:

http://git.musl-libc.org/cgit/musl/blob/src/stdio/vfprintf.c?h=v1.1.6

If you strip out all the hex float support, infinity/nan support, %g/%f/%e variation support, rounding (which will never be needed if you only want exact answers), and other things you might not need, the remaining code is rather simple.

The idea consists to use the keys, when a value is already present in the array keys, the array size stays the same:

function getDistinctRandomNumbers ($nb, $min, $max) {
    if ($max - $min + 1 < $nb)
        return false; // or throw an exception

    $res = array();
    do {
        $res[mt_rand($min, $max)] = 1;
    } while (count($res) !== $nb);
    return array_keys($res); 
}

Pro: This way avoids the use of in_array and doesn't generate a huge array. So, it is fast and preserves a lot of memory.

Cons: when the rate (range/quantity) decreases, the speed decreases too (but stays correct). For a same rate, relative speed increases with the range size.(*)

(*) I understand that fact since there are more free integers to select (in particular for the first steps), but if somebody has the mathematical formula that describes this behaviour, I am interested by, don't hesitate.

Conclusion: The best "general" function seems to be a mix between this function and @Anne function that is more efficient with a little rate. This function should switch between the two ways when a certain quantity is needed and a rate (range/quantity) is reached. So the complexity/time of the test to know that, must be taken in account.

This will be used to change the Html content inside the span

 $('#abc span').html('goes inside the span');

if you want to change the text inside the span, you can use:

 $('#abc span').text('goes inside the span');

I used this library called Parser. It worked for what I needed.

import React, { Component } from 'react';    
import Parser from 'html-react-parser';

class MyComponent extends Component {
  render() {
    <div>{Parser(this.state.message)}</div>
  }
};

This is strange but Logger.getLogger("global") does not work in my setup (as well as Logger.getLogger(Logger.GLOBAL_LOGGER_NAME)).

However Logger.getLogger("") does the job well.

Hope this info also helps somebody...

To generate a random number between min and max, use:

int randNum = rand()%(max-min + 1) + min;

(Includes max and min)

Just add show.json.erb file with the contents

<%= @user.to_json %>

Sometimes it is useful when you need some extra helper methods that are not available in controller, i.e. image_path(@user.avatar) or something to generate additional properties in JSON:

<%= @user.attributes.merge(:avatar => image_path(@user.avatar)).to_json %>

The best way is:

1. Right-click on the output panel.
2. Choose view frame source, then the whole code will appear.

After that you can copy that code, and paste it in your computer.

Its Working Properly

EditText et_mobile= (EditText) findViewById(R.id.edittxt);

et_mobile.setOnFocusChangeListener(new OnFocusChangeListener() {          
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (!hasFocus) {
            // code to execute when EditText loses focus
            if (et_mobile.getText().toString().trim().length() == 0) {
                CommonMethod.showAlert("Please enter name", FeedbackSubmtActivity.this);
            }
        }
    }
});



public static void showAlert(String message, Activity context) {

    final AlertDialog.Builder builder = new AlertDialog.Builder(context);
    builder.setMessage(message).setCancelable(false)
            .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {

                }
            });
    try {
        builder.show();
    } catch (Exception e) {
        e.printStackTrace();
    }

}

A simple way to do this is to call a logging function:

DEBUG = True

def log(s):
    if DEBUG:
        print s

log("hello world")

Then you can change the value of DEBUG and run your code with or without logging.

The standard logging module has a more elaborate mechanism for this.

go to cmd get into file directory and type jupyter notebook filename.ipynb in my case it open code editor and provide local host connection string copy that string and paste in any browser!done

The following works fine for me in Excel 2007. It is simple, and performs a full copy (retains all formatting, etc.):

Sheets("Sheet1").Columns(1).Copy Destination:=Sheets("Sheet2").Columns(2)

"Columns" returns a Range object, and so this is utilizing the "Range.Copy" method. "Destination" is an option to this method - if not provided the default is to copy to the paste buffer. But when provided, it is an easy way to copy.

As when manually copying items in Excel, the size and geometry of the destination must support the range being copied.

I've tried all the above solutions, but none of them worked for me. The following code helped me, when trying to return to MainActivity in a way that onCreate gets called:

Intent.FLAG_ACTIVITY_CLEAR_TOP is the key.

  @Override
  public void onBackPressed() {
      Intent intent = new Intent(this, MainActivity.class);
      intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
      startActivity(intent);
  }

This worked for me:

SET SESSION sql_mode=(SELECT REPLACE(@@sql_mode,'ONLY_FULL_GROUP_BY',''));

git revert HEAD -m 1

In the above code line. "Last argument represents"

• 1 - reverts one commits. 2 - reverts last commits. n - reverts last n commits

or

git reset --hard siriwjdd

I got it working from one I made.

<?php
$dest = imagecreatefrompng('vinyl.png');
$src = imagecreatefromjpeg('cover2.jpg');

imagealphablending($dest, false);
imagesavealpha($dest, true);

imagecopymerge($dest, $src, 10, 9, 0, 0, 181, 180, 100); //have to play with these numbers for it to work for you, etc.

header('Content-Type: image/png');
imagepng($dest);

imagedestroy($dest);
imagedestroy($src);
?>

Adding on to the other answers using requests:

 # download from web

 import requests
 url = 'http://mlg.ucd.ie/files/datasets/bbc.zip'
 content = requests.get(url)

 # unzip the content
 from io import BytesIO
 from zipfile import ZipFile
 f = ZipFile(BytesIO(content.content))
 print(f.namelist())

 # outputs ['bbc.classes', 'bbc.docs', 'bbc.mtx', 'bbc.terms']

Use help(f) to get more functions details for e.g. extractall() which extracts the contents in zip file which later can be used with with open.

You can do this with Jinja's tojson filter, which

Dumps a structure to JSON so that it’s safe to use in <script> tags [and] in any place in HTML with the notable exception of double quoted attributes.

For example, in your Python, write:

some_template.render(list_of_items=list_of_items)

... or, in the context of a Flask endpoint:

return render_template('your_template.html', list_of_items=list_of_items)

Then in your template, write this:

{% for item in list_of_items %}
<span onclick='somefunction({{item | tojson}})'>{{item}}</span><br>
{% endfor %}

(Note that the onclick attribute is single-quoted. This is necessary since |tojson escapes ' characters but not " characters in its output, meaning that it can be safely used in single-quoted HTML attributes but not double-quoted ones.)

Or, to use list_of_items in an inline script instead of an HTML attribute, write this:

<script>
const jsArrayOfItems = {{list_of_items | tojson}};
// ... do something with jsArrayOfItems in JavaScript ...
</script>

DON'T use json.dumps to JSON-encode variables in your Python code and pass the resulting JSON text to your template. This will produce incorrect output for some string values, and will expose you to XSS if you're trying to encode user-provided values. This is because Python's built-in json.dumps doesn't escape characters like < and > (which need escaping to safely template values into inline <script>s, as noted at https://html.spec.whatwg.org/multipage/scripting.html#restrictions-for-contents-of-script-elements) or single quotes (which need escaping to safely template values into single-quoted HTML attributes).

If you're using Flask, note that Flask injects a custom tojson filter instead of using Jinja's version. However, everything written above still applies. The two versions behave almost identically; Flask's just allows for some app-specific configuration that isn't available in Jinja's version.

You are asking two separate questions here:

What's the maximum length of an HTTP GET request?

As already mentioned, HTTP itself doesn't impose any hard-coded limit on request length; but browsers have limits ranging on the 2 KB - 8 KB (255 bytes if we count very old browsers).

Is there a response error defined that the server can/should return if it receives a GET request exceeds this length?

That's the one nobody has answered.

HTTP 1.1 defines status code 414 Request-URI Too Long for the cases where a server-defined limit is reached. You can see further details on RFC 2616.

For the case of client-defined limits, there isn't any sense on the server returning something, because the server won't receive the request at all.

Use CSS background:transparent; to your button/div.

JSFiddle

This will take care of the empty td:

<td style="min-width: 20px;"></td>

You can also add -oHostKeyAlgorithms=+ssh-dss in your ssh line:

ssh -oHostKeyAlgorithms=+ssh-dss user@host

I think the reason is that in C strings are not primitive types, as tomjen said, think in a string as a char array, so you can not do things like:

switch (char[]) { // ...
switch (int[]) { // ...

You need to pass the values of the dict into the Bike constructor before using like that. Or, see the namedtuple -- seems more in line with what you're trying to do.

This one does well its scrolling job. It's very easy to understand, just really few lines of code, well written and totally readable.

For me error occurred with this setup:

AndroidAnnotations Spring Android RestTemplate Module and ...

GsonHttpMessageConverter

Android annotations has some problems with this converted to generate POST request without parameter. Simply parameter new Object() solved it for me.

$('#myform :checkbox').change(function() {
    // this will contain a reference to the checkbox   
    if (this.checked) {
        // the checkbox is now checked 
    } else {
        // the checkbox is now no longer checked
    }
});

Here is some code to implement some copy and paste functions from EditText (thanks to Warpzit for version check). You can hook these to your button's onclick event.

public void copy(View v) {      
    int startSelection = txtNotes.getSelectionStart();
    int endSelection = txtNotes.getSelectionEnd();      
    if ((txtNotes.getText() != null) && (endSelection > startSelection ))
    {
        String selectedText = txtNotes.getText().toString().substring(startSelection, endSelection);                
        int sdk = android.os.Build.VERSION.SDK_INT;
        if(sdk < android.os.Build.VERSION_CODES.HONEYCOMB) {
            android.text.ClipboardManager clipboard = (android.text.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
            clipboard.setText(selectedText);
        } else {
            android.content.ClipboardManager clipboard = (android.content.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); 
            android.content.ClipData clip = android.content.ClipData.newPlainText("WordKeeper",selectedText);
            clipboard.setPrimaryClip(clip);
        }
    }
}   

public void paste(View v) {
    int sdk = android.os.Build.VERSION.SDK_INT;
    if (sdk < android.os.Build.VERSION_CODES.HONEYCOMB) {
        android.text.ClipboardManager clipboard = (android.text.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
        if (clipboard.getText() != null) {
            txtNotes.getText().insert(txtNotes.getSelectionStart(), clipboard.getText());
        }
    } else {
        android.content.ClipboardManager clipboard = (android.content.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
        android.content.ClipData.Item item = clipboard.getPrimaryClip().getItemAt(0);
        if (item.getText() != null) {
            txtNotes.getText().insert(txtNotes.getSelectionStart(), item.getText());
        }
    }
}

Kotlin version:

Use these extensions with infix functions that simplify later calls

infix fun View.below(view: View) {
    (this.layoutParams as? RelativeLayout.LayoutParams)?.addRule(RelativeLayout.BELOW, view.id)
}

infix fun View.leftOf(view: View) {
    (this.layoutParams as? RelativeLayout.LayoutParams)?.addRule(RelativeLayout.LEFT_OF, view.id)
}

infix fun View.alightParentRightIs(aligned: Boolean) {
    val layoutParams = this.layoutParams as? RelativeLayout.LayoutParams
    if (aligned) {
        (this.layoutParams as? RelativeLayout.LayoutParams)?.addRule(RelativeLayout.ALIGN_PARENT_RIGHT)
    } else {
        (this.layoutParams as? RelativeLayout.LayoutParams)?.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, 0)
    }
    this.layoutParams = layoutParams
}

Then use them as infix functions calls:

view1 below view2
view1 leftOf view2
view1 alightParentRightIs true

Or you can use them as normal functions:

view1.below(view2)

Just in case someone really needs a closure like that, it can be done in the following way:

var categoriesPerPage = [[Int]]()
var numPagesClosure: ()->Int {
    return {
        return self.categoriesPerPage.count
    }
}

Give an ID to uniquely identify the button, lets say myBtn

// when DOM is ready
$(document).ready(function () {

     // Attach Button click event listener 
    $("#myBtn").click(function(){

         // show Modal
         $('#myModal').modal('show');
    });
});

Thankfully(?), in SQL Server 2012+, you can now use FORMAT() to achieve this:

FORMAT(@s,'#,0.0000')

[Query]:

declare @s decimal(18,10);
set @s = 1234.1234567;
select replace(convert(varchar,cast(floor(@s) as money),1),'.00',
    '.'+right(cast(@s * 10000 +10000.5 as int),4))

In the first part, we use MONEY->VARCHAR to produce the commas, but FLOOR() is used to ensure the decimals go to .00. This is easily identifiable and replaced with the 4 digits after the decimal place using a mixture of shifting (*10000) and CAST as INT (truncation) to derive the digits.

[Results]:

|   COLUMN_0 |
--------------
| 1,234.1235 |

But unless you have to deliver business reports using SQL Server Management Studio or SQLCMD, this is NEVER the correct solution, even if it can be done. Any front-end or reporting environment has proper functions to handle display formatting.

You can use substr

for example:

new Date().getFullYear().toString().substr(-2)

You need to look at the explain plans, but unless there is an INDEX or PARTITION on COL_A, you are looking at a FULL TABLE SCAN on both tables.

With that in mind, your first example is throwing out some of the data as it does the FULL TABLE SCAN. That result is being sorted by the UNION, then duplicate data is dropped. This gives you your result set.

In the second example, you are pulling the full contents of both tables. That result is likely to be larger. So the UNION is sorting more data, then dropping the duplicate stuff. Then the filter is being applied to give you the result set you are after.

As a general rule, the earlier you filter away data, the smaller the data set, and the faster you will get your results. As always, your milage may vary.

After a lot of searching, the best explanation I've found is from Java Performance Tuning website in Question of the month: 1.4.1 Garbage collection algorithms, January 29th, 2003

Young generation garbage collection algorithms

The (original) copying collector (Enabled by default). When this collector kicks in, all application threads are stopped, and the copying collection proceeds using one thread (which means only one CPU even if on a multi-CPU machine). This is known as a stop-the-world collection, because basically the JVM pauses everything else until the collection is completed.

The parallel copying collector (Enabled using -XX:+UseParNewGC). Like the original copying collector, this is a stop-the-world collector. However this collector parallelizes the copying collection over multiple threads, which is more efficient than the original single-thread copying collector for multi-CPU machines (though not for single-CPU machines). This algorithm potentially speeds up young generation collection by a factor equal to the number of CPUs available, when compared to the original singly-threaded copying collector.

The parallel scavenge collector (Enabled using -XX:UseParallelGC). This is like the previous parallel copying collector, but the algorithm is tuned for gigabyte heaps (over 10GB) on multi-CPU machines. This collection algorithm is designed to maximize throughput while minimizing pauses. It has an optional adaptive tuning policy which will automatically resize heap spaces. If you use this collector, you can only use the the original mark-sweep collector in the old generation (i.e. the newer old generation concurrent collector cannot work with this young generation collector).

From this information, it seems the main difference (apart from CMS cooperation) is that UseParallelGC supports ergonomics while UseParNewGC doesn't.

Manual Switching

From PHP 5.6 => PHP 7.1

Default PHP 5.6 is set on your system and you need to switch to PHP 7.1.

Apache:

$ sudo a2dismod php5.6
$ sudo a2enmod php7.1
$ sudo service apache2 restart

Command Line:

$ sudo update-alternatives --set php /usr/bin/php7.1
$ sudo update-alternatives --set phar /usr/bin/phar7.1
$ sudo update-alternatives --set phar.phar /usr/bin/phar.phar7.1

From PHP 7.1 => PHP 5.6

Default PHP 7.1 is set on your system and you need to switch to PHP 5.6.

Apache:

$ sudo a2dismod php7.1
$ sudo a2enmod php5.6
$ sudo service apache2 restart

One or more of your .cpp files is not being linked in, or some non-inline functions in some class are not defined. In particular, takeaway::textualGame()'s implementation can't be found. Note that you've defined a textualGame() at toplevel, but this is distinct from a takeaway::textualGame() implementation - probably you just forgot the takeaway:: there.

What the error means is that the linker can't find the "vtable" for a class - every class with virtual functions has a "vtable" data structure associated with it. In GCC, this vtable is generated in the same .cpp file as the first listed non-inline member of the class; if there's no non-inline members, it will be generated wherever you instantiate the class, I believe. So you're probably failing to link the .cpp file with that first-listed non-inline member, or never defining that member in the first place.
