Using j-text-utils you may print to console a table like:

And it as simple as:

TextTable tt = new TextTable(columnNames, data);                                                         
tt.printTable();   

The API also allows sorting and row numbering ...

It may be too late for my answer, but I think this is not that hard. You can extend the PDFTextStripper class and override the writePage() and processTextPosition(...) methods. In your case I assume that the column headers are always the same. That means that you know the x-coordinate of each column heading and you can compare the the x-coordinate of the numbers to those of the column headings. If they are close enough (you have to test to decide how close) then you can say that that number belongs to that column.

Another approach would be to intercept the "charactersByArticle" Vector after each page is written:

@Override
public void writePage() throws IOException {
    super.writePage();
    final Vector<List<TextPosition>> pageText = getCharactersByArticle();
    //now you have all the characters on that page
    //to do what you want with them
}

Knowing your columns, you can do your comparison of the x-coordinates to decide what column every number belongs to.

The reason you don't have any spaces between numbers is because you have to set the word separator string.

I hope this is useful to you or to others who might be trying similar things.

Use p{width} column specifier: e.g. \begin{tabular}{ l p{10cm} } will put column's content into 10cm-wide parbox, and the text will be properly broken to several lines, like in normal paragraph.

You can also use tabular* environment to specify width for the entire table.

\usepackage{array} in the preamble

then this:

\begin{tabular}{| >{\centering\arraybackslash}m{1in} | >{\centering\arraybackslash}m{1in} |}

note that the "m" for fixed with column is provided by the array package, and will give you vertical centering (if you don't want this just go back to "p"

Bootstrap 4.0 gives an option to modify modal data using jquery: https://getbootstrap.com/docs/4.0/components/modal/#varying-modal-content

Here is the script tag on the docs :

$('#exampleModal').on('show.bs.modal', function (event) {
  var button = $(event.relatedTarget) // Button that triggered the modal
  var recipient = button.data('whatever') // Extract info from data-* attributes
  // If necessary, you could initiate an AJAX request here (and then do the updating in a callback).
  // Update the modal's content. We'll use jQuery here, but you could use a data binding library or other methods instead.
  var modal = $(this)
  modal.find('.modal-title').text('New message to ' + recipient)
  modal.find('.modal-body input').val(recipient)
})

It works for the most part. Only call to modal was not working. Here is a modification on the script that works for me:

$(document).on('show.bs.modal', '#exampleModal',function(event){
... // same as in above script
})

Give this a try. It basically calculates the number of days that has passed on DateTime.Now, then subtracts one from that and uses the new value to find the first of the current month. From there it uses that DateTime and uses .AddMonths(-1) to get the first of the previous month.

Getting the last day of last month does basically the same thing except it adds one to number of days in the month and subtracts that value from DateTime.Now.AddDays, giving you the last day of the previous month.

int NumberofDays = DateTime.Now.Day;
int FirstDay = NumberofDays - 1;
int LastDay = NumberofDays + 1;
DateTime FirstofThisMonth = DateTime.Now.AddDays(-FirstDay);
DateTime LastDayOfLastMonth = DateTime.Now.AddDays(-LastDay);
DateTime CheckLastMonth = FirstofThisMonth.AddMonths(-1);

Reference types do not store the object directly into the variable to which it is assigned, so the object variable in the example below, doesn’t actually contain the object instance. Instead, it holds a pointer (or reference) to the location in memory, where the object exists.

var object = new Object();

if you assign one reference typed variable to another, each variable gets a copy of the pointer, and both still reference to the same object in memory.

var object1 = new Object();
var object2 = object1;

JavaScript is a garbage-collected language, so you don’t really need to worry about memory allocations when you use reference types. However, it’s best to dereference objects that you no longer need so that the garbage collector can free up that memory. The best way to do this is to set the object variable to null.

var object1 = new Object();
// do something
object1 = null; // dereference

Dereferencing objects is especially important in very large applications that use millions of objects.

On OSX and VSCode 1.50.0 all I had to do was to close and restart VSCode and the problem went away.

it's work for me html:

$("#btnSaveSchedule").text("new value");

From the command line issue

mongo --quiet --eval  "printjson(db.adminCommand('listDatabases'))"

MSVC 2015 Update 1, cl.exe version 19.00.24215.1:

#include <iostream>

template<typename X, typename Y>

{
  template<typename Z>
  static void f()
  {
    std::cout << "from A::f():" << std::endl
      << __FUNCTION__ << std::endl
      << __func__ << std::endl
      << __FUNCSIG__ << std::endl;
  }
};

void main()
{
  std::cout << "from main():" << std::endl
    << __FUNCTION__ << std::endl
    << __func__ << std::endl
    << __FUNCSIG__ << std::endl << std::endl;

  A<int, float>::f<bool>();
}

output:

from main():
main
main
int __cdecl main(void)

from A::f():
A<int,float>::f
f
void __cdecl A<int,float>::f<bool>(void)

Using of __PRETTY_FUNCTION__ triggers undeclared identifier error, as expected.

you can just do:

element.removeAttribute("style")

TSQL: Dates- need to look for gaps in dates between Two Date

select
distinct
e1.enddate,
e3.startdate,
DATEDIFF(DAY,e1.enddate,e3.startdate)-1 as [Datediff]
from #temp e1 
   join #temp e3 on e1.enddate < e3.startdate          
       /* Finds the next start Time */
and e3.startdate = (select min(startdate) from #temp e5
where e5.startdate > e1.enddate)
and not exists (select *  /* Eliminates e1 rows if it is overlapped */
from #temp e5 
where e5.startdate < e1.enddate and e5.enddate > e1.enddate);

First of all, this what is written in documentation. I think it is one of your class fields, not the main one - and how you want deserialiser to construct it back w/o parameterless construction ?

I think there is a workaround to make constructor private.

You cannot update it. You'll have to save the document using a new _id, and then remove the old document.

// store the document in a variable
doc = db.clients.findOne({_id: ObjectId("4cc45467c55f4d2d2a000002")})

// set a new _id on the document
doc._id = ObjectId("4c8a331bda76c559ef000004")

// insert the document, using the new _id
db.clients.insert(doc)

// remove the document with the old _id
db.clients.remove({_id: ObjectId("4cc45467c55f4d2d2a000002")})

Another consideration, if a field is required or has a limited range, perform the check in the constructor:

public Book(String title)
{
    if (title==null)
        throw new IllegalArgumentException("title can't be null");
    this.title = title;
}

import os
import cv2
rootdir = "directory path"
for subdir, dirs, files in os.walk(rootdir):
    for file in files:
        frame = cv2.imread(os.path.join(subdir, file)) 

String to JSON using Jackson with com.fasterxml.jackson.databind:

Assuming your json-string represents as this: jsonString = {"phonetype":"N95","cat":"WP"}

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
/**
 * Simple code exmpl
 */
ObjectMapper mapper = new ObjectMapper();
JsonNode node = mapper.readTree(jsonString);
String phoneType = node.get("phonetype").asText();
String cat = node.get("cat").asText();

    var ele = document.getElementById('newSkill')
    ele.onchange = function(){
            var length = ele.children.length
            for(var i=0; i<length;i++){
                if(ele.children[i].selected){alert(ele.children[i].text)};              
            }
    }   

AD registers Service Location (SRV) resource records in its DNS server which you can query to get the port and the hostname of the responsible LDAP server in your domain.

Just try this on the command-line:

C:\> nslookup 
> set types=all
> _ldap._tcp.<<your.AD.domain>>
_ldap._tcp.<<your.AD.domain>>  SRV service location:
      priority       = 0
      weight         = 100
      port           = 389
      svr hostname   = <<ldap.hostname>>.<<your.AD.domain>>

(provided that your nameserver is the AD nameserver which should be the case for the AD to function properly)

Please see Active Directory SRV Records and Windows 2000 DNS white paper for more information.

You can also pass value directly via URL.

If you want to call method public static void calling(string name){....}

then you should call usingHttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create("http://localhost:****/Report/calling?name=Priya); webrequest.Method = "GET"; webrequest.ContentType = "application/text";

Just make sure you are using ?Object = value in URL

1. Installing OpenCV 2.4.3

First, get OpenCV 2.4.3 from sourceforge.net. Its a self-extracting so just double click to start the installation. Install it in a directory, say C:\.

Wait until all files get extracted. It will create a new directory C:\opencv which contains OpenCV header files, libraries, code samples, etc.

Now you need to add the directory C:\opencv\build\x86\vc10\bin to your system PATH. This directory contains OpenCV DLLs required for running your code.

Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...

On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin; (3), then click Ok.

On some computers, you may need to restart your computer for the system to recognize the environment path variables.

This will completes the OpenCV 2.4.3 installation on your computer.

2. Create a new project and set up Visual C++

Open Visual C++ and select File → New → Project... → Visual C++ → Empty Project. Give a name for your project (e.g: cvtest) and set the project location (e.g: c:\projects).

Click Ok. Visual C++ will create an empty project.

Make sure that "Debug" is selected in the solution configuration combobox. Right-click cvtest and select Properties → VC++ Directories.

Select Include Directories to add a new entry and type C:\opencv\build\include.

Click Ok to close the dialog.

Back to the Property dialog, select Library Directories to add a new entry and type C:\opencv\build\x86\vc10\lib.

Click Ok to close the dialog.

Back to the property dialog, select Linker → Input → Additional Dependencies to add new entries. On the popup dialog, type the files below:

opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib
opencv_features2d243d.lib
opencv_flann243d.lib
opencv_gpu243d.lib
opencv_haartraining_engined.lib
opencv_highgui243d.lib
opencv_imgproc243d.lib
opencv_legacy243d.lib
opencv_ml243d.lib
opencv_nonfree243d.lib
opencv_objdetect243d.lib
opencv_photo243d.lib
opencv_stitching243d.lib
opencv_ts243d.lib
opencv_video243d.lib
opencv_videostab243d.lib

Note that the filenames end with "d" (for "debug"). Also note that if you have installed another version of OpenCV (say 2.4.9) these filenames will end with 249d instead of 243d (opencv_core249d.lib..etc).

Click Ok to close the dialog. Click Ok on the project properties dialog to save all settings.

NOTE:

These steps will configure Visual C++ for the "Debug" solution. For "Release" solution (optional), you need to repeat adding the OpenCV directories and in Additional Dependencies section, use:

opencv_core243.lib
opencv_imgproc243.lib
...

instead of:

opencv_core243d.lib
opencv_imgproc243d.lib
...

You've done setting up Visual C++, now is the time to write the real code. Right click your project and select Add → New Item... → Visual C++ → C++ File.

Name your file (e.g: loadimg.cpp) and click Ok. Type the code below in the editor:

#include <opencv2/highgui/highgui.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main()
{
    Mat im = imread("c:/full/path/to/lena.jpg");
    if (im.empty()) 
    {
        cout << "Cannot load image!" << endl;
        return -1;
    }
    imshow("Image", im);
    waitKey(0);
}

The code above will load c:\full\path\to\lena.jpg and display the image. You can use any image you like, just make sure the path to the image is correct.

Type F5 to compile the code, and it will display the image in a nice window.

And that is your first OpenCV program!

3. Where to go from here?

Now that your OpenCV environment is ready, what's next?

1. Go to the samples dir → c:\opencv\samples\cpp.
2. Read and compile some code.
3. Write your own code.

The Angular microsyntax lets you configure a directive in a compact, friendly string. The microsyntax parser translates that string into attributes on the <ng-template>. The let keyword declares a template input variable that you reference within the template.

If you only want to solve the extremely limited set of equations mx + c = y for positive integer m, c, y, then this will do:

import re
def solve_linear_equation ( equ ):
    """
    Given an input string of the format "3x+2=6", solves for x.
    The format must be as shown - no whitespace, no decimal numbers,
    no negative numbers.
    """
    match = re.match(r"(\d+)x\+(\d+)=(\d+)", equ)
    m, c, y = match.groups()
    m, c, y = float(m), float(c), float(y) # Convert from strings to numbers
    x = (y-c)/m
    print ("x = %f" % x)

Some tests:

>>> solve_linear_equation("2x+4=12")
x = 4.000000
>>> solve_linear_equation("123x+456=789")
x = 2.707317
>>> 

If you want to recognise and solve arbitrary equations, like sin(x) + e^(i*pi*x) = 1, then you will need to implement some kind of symbolic maths engine, similar to maxima, Mathematica, MATLAB's solve() or Symbolic Toolbox, etc. As a novice, this is beyond your ken.

.className {
   content: '\&#x2713';
}

Using CSS content Property you can show tick with an image or other codesign.

Even i recently had the same query....some how none of the above mentioned setmaxzoom or else map:cameraZoom="13" did not work So i found that the depenedency which i used was old please make sure your dependency for google maps is correct this is the newest use this

To add one day to a date object:

var date = new Date();

// add a day
date.setDate(date.getDate() + 1);

Extract characters from a string:

var str = "Hello world!";
var res = str.substring(1,4);

The result of res will be:

ell

http://www.w3schools.com/jsref/jsref_substring.asp

$('.dep_buttons').mouseover(function(){
    $(this).text().substring(0,25);
    if($(this).text().length > 30) {
        $(this).stop().animate({height:"150px"},150);
    }
    $(".dep_buttons").mouseout(function(){
        $(this).stop().animate({height:"40px"},150);
    });
});

I know the accepted answer is great but for anyone who is looking for a hover like feel you can use setTimeout on mouseover and save the handle in a map (of let's say list ids to setTimeout Handle). On mouseover clear the handle from setTimeout and delete it from the map

onMouseOver={() => this.onMouseOver(someId)}
onMouseOut={() => this.onMouseOut(someId)

And implement the map as follows:

onMouseOver(listId: string) {
  this.setState({
    ... // whatever
  });

  const handle = setTimeout(() => {
    scrollPreviewToComponentId(listId);
  }, 1000); // Replace 1000ms with any time you feel is good enough for your hover action
  this.hoverHandleMap[listId] = handle;
}

onMouseOut(listId: string) {
  this.setState({
    ... // whatever
  });

  const handle = this.hoverHandleMap[listId];
  clearTimeout(handle);
  delete this.hoverHandleMap[listId];
}

And the map is like so,

hoverHandleMap: { [listId: string]: NodeJS.Timeout } = {};

I prefer onMouseOver and onMouseOut because it also applies to all the children in the HTMLElement. If this is not required you may use onMouseEnter and onMouseLeave respectively.

return(nds)
}

In Windows when a process terminates, the OS closes the associated window. This happens with all programs (and is generally desirable behaviour), but people never cease to be surprised when it happens to the ones they write themselves.

I am being slightly harsh perhaps; many IDE's execute the user's process in a shell as a child process, so that it does not own the window so it won't close when the process terminates. Although this would be trivial, Dev-C++ does not do that.

Be aware that when Dev-C++ was popular, this question appeard at least twice a day on Dev-C++'s own forum on Sourceforge. For that reason the forum has a "Read First" thread that provides a suggested solution amongst solutions to many other common problems. You should read it here.

Note that Dev-C++ is somewhat old and no longer actively maintained. It suffers most significantly from an almost unusable and very limited debugger integration. Traffic on the Dev-C++ forum has been dropping off since the release of VC++ 2005 Express, and is now down to a two or three posts a week rather than the 10 or so a day it had in 2005. All this suggest that you should consider an alternative tool IMO.

The default value for bool is false. See this table for a great reference on default values. The only reason it would not be false when you check it is if you initialize/set it to true.

<input type="checkbox" id="something" />

$("#something").click( function(){
   if( $(this).is(':checked') ) alert("checked");
});

Edit: Doing this will not catch when the checkbox changes for other reasons than a click, like using the keyboard. To avoid this problem, listen to changeinstead of click.

For checking/unchecking programmatically, take a look at Why isn't my checkbox change event triggered?

To sum it up,in object oriented programming, everything is modeled into classes and objects. Classes contain properties and methods. Public, private and protected keywords are used to specify access to these members(properties and methods) of a class from other classes or other .dlls or even other applications.

I based my answer on Daniel López Lacalle and this post http://www.henning.ms/2013/09/09/viewpager-that-simply-dont-measure-up/. The problem with Daniel's answer is that in some cases my children had a height of zero. The solution was to unfortunately measure twice.

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    int mode = MeasureSpec.getMode(heightMeasureSpec);
    // Unspecified means that the ViewPager is in a ScrollView WRAP_CONTENT.
    // At Most means that the ViewPager is not in a ScrollView WRAP_CONTENT.
    if (mode == MeasureSpec.UNSPECIFIED || mode == MeasureSpec.AT_MOST) {
        // super has to be called in the beginning so the child views can be initialized.
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        int height = 0;
        for (int i = 0; i < getChildCount(); i++) {
            View child = getChildAt(i);
            child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
            int h = child.getMeasuredHeight();
            if (h > height) height = h;
        }
        heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);
    }
    // super has to be called again so the new specs are treated as exact measurements
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

This also lets you set a height on the ViewPager if you so want to or just wrap_content.

LIMIT limit OFFSET offset will work.

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

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

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

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

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

• Optimize query with OFFSET on large table

>>> dict(zip([1, 2, 3, 4], ['a', 'b', 'c', 'd']))
{1: 'a', 2: 'b', 3: 'c', 4: 'd'}

If they are not the same size, zip will truncate the longer one.

There is an OpenSSH package for Windows which is basically a stripped down Cygwin. It has an msi-Installer and (after setting your path accordingly) works with "vsagrant ssh":

Old question, but I just ran into this. Sometimes your files are UTF-8 with a BOM at the start, and your template engine doesn't like that. So when you include your template, you get another (invisible) BOM inserted into your page...

<body>{INVISIBLE BOM HERE}...</body>

This causes a gap at the start of your page, where the browser renders the BOM, but it looks invisible to you (and in the inspector, just shows up as whitespace/quotes.

Save your template files as UTF-8 without BOM, or change your template engine to correctly handle UTF8/BOM documents.

Use:

overflow: hidden;
height: 100%;
position: fixed;
width: 100%;

There are many ways to create protection against session hijack, however all of them are either reducing user satisfaction or are not secure.

• IP and/or X-FORWARDED-FOR checks. These work, and are pretty secure... but imagine the pain of users. They come to an office with WiFi, they get new IP address and lose the session. Got to log-in again.

• User Agent checks. Same as above, new version of browser is out, and you lose a session. Additionally, these are really easy to "hack". It's trivial for hackers to send fake UA strings.

• localStorage token. On log-on generate a token, store it in browser storage and store it to encrypted cookie (encrypted on server-side). This has no side-effects for user (localStorage persists through browser upgrades). It's not as secure - as it's just security through obscurity. Additionally you could add some logic (encryption/decryption) to JS to further obscure it.

• Cookie reissuing. This is probably the right way to do it. The trick is to only allow one client to use a cookie at a time. So, active user will have cookie re-issued every hour or less. Old cookie is invalidated if new one is issued. Hacks are still possible, but much harder to do - either hacker or valid user will get access rejected.

Your find should look like that to avoid sending directory names to sed:

find ./ -type f -exec sed -i -e 's/apple/orange/g' {} \;

You're looking for implode()

$string = implode(",", $array);

When you declare

var a=[];

you are declaring a empty array.

But when you are declaring

var a={};

you are declaring a Object .

Although Array is also Object in Javascript but it is numeric key paired values. Which have all the functionality of object but Added some few method of Array like Push,Splice,Length and so on.

So if you want Some values where you need to use numeric keys use Array. else use object. you can Create object like:

var a={name:"abc",age:"14"}; 

And can access values like

console.log(a.name);

Both GET and POST are used by the browser to request a single resource from the server. Each resource requires a separate GET or POST request.

1. The GET method is most commonly (and is the default method) used by browsers to retrieve information from servers. When using the GET method the 3rd section of the request packet, which is the request body, remains empty.

The GET method is used in one of two ways: When no method is specified, that is when you or the browser is requesting a simple resource such as an HTML page, an image, etc. When a form is submitted, and you choose method=GET on the HTML tag. If the GET method is used with an HTML form, then the data collected through the form is sent to the server by appending a "?" to the end of the URL, and then adding all name=value pairs (name of the html form field and value entered in that field) separated by an "&" Example: GET /sultans/shop//form1.jsp?name=Sam%20Sultan&iceCream=vanilla HTTP/1.0 optional headeroptional header<< empty line >>>

The name=value form data will be stored in an environment variable called QUERY_STRING. This variable will be sent to a processing program (such as JSP, Java servlet, PHP etc.)

2. The POST method is used when you create an HTML form, and request method=POST as part of the tag. The POST method allows the client to send form data to the server in the request body section of the request (as discussed earlier). The data is encoded and is formatted similar to the GET method, except that the data is sent to the program through the standard input.

Example: POST /sultans/shop//form1.jsp HTTP/1.0 optional headeroptional header<< empty line >>> name=Sam%20Sultan&iceCream=vanilla

When using the post method, the QUERY_STRING environment variable will be empty. Advantages/Disadvantages of GET vs. POST

Advantages of the GET method: Slightly faster Parameters can be entered via a form or by appending them after the URL Page can be bookmarked with its parameters

Disadvantages of the GET method: Can only send 4K worth of data. (You should not use it when using a textarea field) Parameters are visible at the end of the URL

Advantages of the POST method: Parameters are not visible at the end of the URL. (Use for sensitive data) Can send more that 4K worth of data to server

Disadvantages of the POST method: Can cannot be bookmarked with its data

eval(compile(myvar,'<str>','eval'))(myargs)

compile(...,'eval') allows only a single statement, so that there can't be arbitrary commands after a call, or there will be a SyntaxError. Then a tiny bit of validation can at least constrain the expression to something in your power, like testing for 'mypackage' to start.

If you need to store null characters in text fields and don't want to change your data type other than text then you can follow my solution too:

Before insert:

myValue = myValue.replaceAll("\u0000", "SomeVerySpecialText")

After select:

myValue = myValue.replaceAll("SomeVerySpecialText","\u0000")

I've used "null" as my SomeVerySpecialText which I am sure that there will be no any "null" string in my values at all.

if you use to generate the id = GenerationType.AUTO strategy in your entity.

Replaces user.setId (1) by user.setId (null), and the problem is solved.

The data-reactid attribute is a custom attribute used so that React can uniquely identify its components within the DOM.

This is important because React applications can be rendered at the server as well as the client. Internally React builds up a representation of references to the DOM nodes that make up your application (simplified version is below).

{
  id: '.1oqi7occu80',
  node: DivRef,
  children: [
    {
      id: '.1oqi7occu80.0',
      node: SpanRef,
      children: [
        {
          id: '.1oqi7occu80.0.0',
          node: InputRef,
          children: []
        }
      ]
    }
  ]
}

There's no way to share the actual object references between the server and the client and sending a serialized version of the entire component tree is potentially expensive. When the application is rendered at the server and React is loaded at the client, the only data it has are the data-reactid attributes.

<div data-reactid='.loqi70ccu80'>
  <span data-reactid='.loqi70ccu80.0'>
    <input data-reactid='.loqi70ccu80.0' />
  </span>
</div>

It needs to be able to convert that back into the data structure above. The way it does that is with the unique data-reactid attributes. This is called inflating the component tree.

You might also notice that if React renders at the client-side, it uses the data-reactid attribute, even though it doesn't need to lose its references. In some browsers, it inserts your application into the DOM using .innerHTML then it inflates the component tree straight away, as a performance boost.

The other interesting difference is that client-side rendered React ids will have an incremental integer format (like .0.1.4.3), whereas server-rendered ones will be prefixed with a random string (such as .loqi70ccu80.1.4.3). This is because the application might be rendered across multiple servers and it's important that there are no collisions. At the client-side, there is only one rendering process, which means counters can be used to ensure unique ids.

React 15 uses document.createElement instead, so client rendered markup won't include these attributes anymore.

You could use the encodeURIComponent to safely URL encode parts of a query string:

var array = JSON.stringify([ 'foo', 'bar' ]);
var url = 'http://example.com/?data=' + encodeURIComponent(array);

or if you are sending this as an AJAX request:

var array = JSON.stringify([ 'foo', 'bar' ]);
$.ajax({
    url: 'http://example.com/',
    type: 'GET',
    data: { data: array },
    success: function(result) {
        // process the results
    }
});

In order to distinct all datatable columns, you can easily retrieve the names of the columns in a string array

public static DataTable RemoveDuplicateRows(this DataTable dataTable)
{
    List<string> columnNames = new List<string>();
    foreach (DataColumn col in dataTable.Columns)
    {
        columnNames.Add(col.ColumnName);
    }
    return dataTable.DefaultView.ToTable(true, columnNames.Select(c => c.ToString()).ToArray());
}

As you can notice, I thought of using it as an extension to DataTable class

var marker = new google.maps.Marker({
                position: new google.maps.LatLng(23.016427,72.571156),
                map: map,
                icon: 'images/map_marker_icon.png',
                title: 'Hi..!'
            });

apply local path on icon only

To put it a different way "id()" is not what you care about. You want to know if the variable name can be modified without harming the source variable name.

If you're used to C, then these are like pointer variables except you can't de-reference them to modify what they point at, but id() will tell you where they currently point.

The problem for python programmers comes when you consider deeper structures like lists or dicts:

>>> o={'a': 10}

Here o and x refer to the same dict o['a'] and x['a'], and that dict is "mutable" in the sense that you can change the value for key 'a'. That's why "y" needs to be a copy and y['a'] can refer to something else.

I used this answer with my local directory ( for example E:// ) it is worked fine for the first directory and for the seconde directory the output made a java null pointer exception, after searching for the reason i discover that the problem was created by the hidden directory, and this directory was created by windows to avoid this problem just use this

public void recursiveSearch(File file ) {
 File[] filesList = file.listFiles();
    for (File f : filesList) {
        if (f.isDirectory() && !f.isHidden()) {
            System.out.println("Directoy name is  -------------->" + f.getName());
            recursiveSearch(f);
        }
        if( f.isFile() ){
            System.out.println("File name is  -------------->" + f.getName());

If you want to check repetition more than 1 in descending order then implement below query.

SELECT   duplicate_data,COUNT(duplicate_data) AS duplicate_data
FROM     duplicate_data_table_name 
GROUP BY duplicate_data
HAVING   COUNT(duplicate_data) > 1
ORDER BY COUNT(duplicate_data) DESC

If want simple count query.

SELECT   COUNT(duplicate_data) AS duplicate_data
FROM     duplicate_data_table_name 
GROUP BY duplicate_data
ORDER BY COUNT(duplicate_data) DESC

The Communicating with Other Fragments guide says the Fragments should communicate through the associated Activity.

Often you will want one Fragment to communicate with another, for example to change the content based on a user event. All Fragment-to-Fragment communication is done through the associated Activity. Two Fragments should never communicate directly.

I believe that is is a move operator. operator= is the assignment operator, say vector x = vector y. The clear() function call sounds like as if it is deleting the contents of the vector to prevent a memory leak. The operator returns a pointer to the new vector.

This way,

std::vector<int> a(100, 10);
std::vector<int> b = a;
for(unsigned int i = 0; i < b.size(); i++)
{
    std::cout << b[i] << ' ';
}

Even though we gave vector a values, vector b has the values. It's the magic of the operator=()!

MSDN -- How to create a move constructor

The example provided by @tster shows how to create a list of list. I will provide an example for iterating over such a list.

Iterator<List<String>> iter = listOlist.iterator();
while(iter.hasNext()){
    Iterator<String> siter = iter.next().iterator();
    while(siter.hasNext()){
         String s = siter.next();
         System.out.println(s);
     }
}

As far as I understand it, the sort function in the collection class can only be used to sort collections implementing the comparable interface.

You are supplying it a array of integers. You should probably wrap this around one of the know Wrapper classes such as Integer. Integer implements comparable.

Its been a long time since I have worked on some serious Java, however reading some matter on the sort function will help.

Short and sweet.

Using Java 8 you can do following :

Map<Key, Value> result= results
                       .stream()
                       .collect(Collectors.toMap(Value::getName,Function.identity()));

Value can be any object you use.

You can only use

     Object& return_Object();

if the object returned has a greater scope than the function. For example, you can use it if you have a class where it is encapsulated. If you create an object in your function, use pointers. If you want to modify an existing object, pass it as an argument.

  class  MyClass{
      private:
        Object myObj;

      public:
         Object& return_Object() {
            return myObj;
         }

         Object* return_created_Object() {
            return new Object();
         }

         bool modify_Object( Object& obj) {
            //  obj = myObj; return true; both possible
            return obj.modifySomething() == true;
         }
   };

However, I'm pretty sure that Google actually stores your email and password (at the time of saving to the device) for times like these. So when it needs to be unlocked, it won't require an internet connection.

I could be wrong. Either way, when I had this issue, I had internet connectivity, and I knew my username and password and it didn't care, kept saying they were wrong (even though I was logging into my email). Had to format the phone at the time!

Since 0.17, you have to use the explicit conversions:

pd.to_datetime, pd.to_timedelta and pd.to_numeric

(As mentioned below, no more "magic", convert_objects has been deprecated in 0.17)

df = pd.DataFrame({'x': {0: 'a', 1: 'b'}, 'y': {0: '1', 1: '2'}, 'z': {0: '2018-05-01', 1: '2018-05-02'}})

df.dtypes

x    object
y    object
z    object
dtype: object

df

   x  y           z
0  a  1  2018-05-01
1  b  2  2018-05-02

You can apply these to each column you want to convert:

df["y"] = pd.to_numeric(df["y"])
df["z"] = pd.to_datetime(df["z"])    
df

   x  y          z
0  a  1 2018-05-01
1  b  2 2018-05-02

df.dtypes

x            object
y             int64
z    datetime64[ns]
dtype: object

and confirm the dtype is updated.

1  b  2

In [24]: df.convert_objects(convert_numeric=True).dtypes
Out[24]:

This is perfect code but it cannot add a new row:

dataGridView1.Rows[rowIndex].Cells[columnIndex].Value = value;

But this code can insert a new row:

var index = this.dataGridView1.Rows.Add();
this.dataGridView1.Rows[index].Cells[1].Value = "1";
this.dataGridView1.Rows[index].Cells[2].Value = "Baqar";

First of all consider using query parameters in prepared statements:

PreparedStatement stm = c.prepareStatement("UPDATE user_table SET name=? WHERE id=?");
stm.setString(1, "the name");
stm.setInt(2, 345);
stm.executeUpdate();

The other thing that can be done is to keep all queries in properties file. For example in a queries.properties file can place the above query:

update_query=UPDATE user_table SET name=? WHERE id=?

Then with the help of a simple utility class:

public class Queries {

    private static final String propFileName = "queries.properties";
    private static Properties props;

    public static Properties getQueries() throws SQLException {
        InputStream is = 
            Queries.class.getResourceAsStream("/" + propFileName);
        if (is == null){
            throw new SQLException("Unable to load property file: " + propFileName);
        }
        //singleton
        if(props == null){
            props = new Properties();
            try {
                props.load(is);
            } catch (IOException e) {
                throw new SQLException("Unable to load property file: " + propFileName + "\n" + e.getMessage());
            }           
        }
        return props;
    }

    public static String getQuery(String query) throws SQLException{
        return getQueries().getProperty(query);
    }

}

you might use your queries as follows:

PreparedStatement stm = c.prepareStatement(Queries.getQuery("update_query"));

This is a rather simple solution, but works well.

Add my two cents, if you're using windows commnad line:

git config --list | findstr user.name will give username directly.

The findstr here is quite similar to grep in linux.

Per this blog post, you can add css classes to your fields using a custom template filter.

from django import template
register = template.Library()

@register.filter(name='addcss')
def addcss(field, css):
    return field.as_widget(attrs={"class":css})

Put this in your app's templatetags/ folder and you can now do

{{field|addcss:"form-control"}}

>>> list(my_dataframe)
['y', 'gdp', 'cap']

To list the columns of a dataframe while in debugger mode, use a list comprehension:

>>> [c for c in my_dataframe]
['y', 'gdp', 'cap']

By the way, you can get a sorted list simply by using sorted:

>>> sorted(my_dataframe)
['cap', 'gdp', 'y']

CSS really doesn't have the ability to modify an object in the same manner as JavaScript, so in short - no.

Some answers are partially wrong, and some facts in them are partially wrong as well.

Answer your question: Yes! You can.

In Typescript

class A {
    private a1;
    private a2;


}

Generates the following code in Javascript:

var A = /** @class */ (function () {
    function A() {
    }
    return A;
}());

as @Erik_Cupal said, you could just do:

let a = new A();
let array = return Object.getOwnPropertyNames(a);

But this is incomplete. What happens if your class has a custom constructor? You need to do a trick with Typescript because it will not compile. You need to assign as any:

let className:any = A;
let a = new className();// the members will have value undefined

A general solution will be:

class A {
    private a1;
    private a2;
    constructor(a1:number, a2:string){
        this.a1 = a1;
        this.a2 = a2;
    }
}

class Describer{

   describeClass( typeOfClass:any){
       let a = new typeOfClass();
       let array = Object.getOwnPropertyNames(a);
       return array;//you can apply any filter here
   }
}

For better understanding this will reference depending on the context.

Put your Image in drawable folder. Here my image file name is left.png

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_x="118dp"
    android:layout_y="95dp"
    android:background="@drawable/left"
    android:onClick="toast"
    android:text=" " />

Assuming you have something like so:

public class MyFirstClass {
   ...
   public ArrayList<Integer> myNumbers()    {
    ArrayList<Integer> numbers = new ArrayList<Integer>();
    numbers.add(5);
    numbers.add(11);
    numbers.add(3);
    return(numbers);
   }
   ...
}

You can call that method like so:

public class MySecondClass {
    ...
    MyFirstClass m1 = new MyFirstClass();
    List<Integer> myList = m1.myNumbers();
    ...
}

Since the method you are trying to call is not static, you will have to create an instance of the class which provides this method. Once you create the instance, you will then have access to the method.

Note, that in the code example above, I used this line: List<Integer> myList = m1.myNumbers();. This can be changed by the following: ArrayList<Integer> myList = m1.myNumbers();. However, it is usually recommended to program to an interface, and not to a concrete implementation, so my suggestion for the method you are using would be to do something like so:

public List<Integer> myNumbers()    {
    List<Integer> numbers = new ArrayList<Integer>();
    numbers.add(5);
    numbers.add(11);
    numbers.add(3);
    return(numbers);
   }

This will allow you to assign the contents of that list to whatever implements the List interface.

The following is a "repr way" to check it. Also it works with lambda.

def a():pass
type(a) #<class 'function'>
str(type(a))=="<class 'function'>" #True

b = lambda x:x*2
str(type(b))=="<class 'function'>" #True

In researching Matt's comment, I have revised my original statement. He is correct, there will be a difference in performance between an inline table valued function (ITVF) and a multi-statement table valued function (MSTVF) even if they both simply execute a SELECT statement. SQL Server will treat an ITVF somewhat like a VIEW in that it will calculate an execution plan using the latest statistics on the tables in question. A MSTVF is equivalent to stuffing the entire contents of your SELECT statement into a table variable and then joining to that. Thus, the compiler cannot use any table statistics on the tables in the MSTVF. So, all things being equal, (which they rarely are), the ITVF will perform better than the MSTVF. In my tests, the performance difference in completion time was negligible however from a statistics standpoint, it was noticeable.

In your case, the two functions are not functionally equivalent. The MSTV function does an extra query each time it is called and, most importantly, filters on the customer id. In a large query, the optimizer would not be able to take advantage of other types of joins as it would need to call the function for each customerId passed. However, if you re-wrote your MSTV function like so:

CREATE FUNCTION MyNS.GetLastShipped()
RETURNS @CustomerOrder TABLE
    (
    SaleOrderID    INT         NOT NULL,
    CustomerID      INT         NOT NULL,
    OrderDate       DATETIME    NOT NULL,
    OrderQty        INT         NOT NULL
    )
AS
BEGIN
    INSERT @CustomerOrder
    SELECT a.SalesOrderID, a.CustomerID, a.OrderDate, b.OrderQty
    FROM Sales.SalesOrderHeader a 
        INNER JOIN Sales.SalesOrderHeader b
            ON a.SalesOrderID = b.SalesOrderID
        INNER JOIN Production.Product c 
            ON b.ProductID = c.ProductID
    WHERE a.OrderDate = (
                        Select Max(SH1.OrderDate)
                        FROM Sales.SalesOrderHeader As SH1
                        WHERE SH1.CustomerID = A.CustomerId
                        )
    RETURN
END
GO

In a query, the optimizer would be able to call that function once and build a better execution plan but it still would not be better than an equivalent, non-parameterized ITVS or a VIEW.

ITVFs should be preferred over a MSTVFs when feasible because the datatypes, nullability and collation from the columns in the table whereas you declare those properties in a multi-statement table valued function and, importantly, you will get better execution plans from the ITVF. In my experience, I have not found many circumstances where an ITVF was a better option than a VIEW but mileage may vary.

Thanks to Matt.

Since I saw this come up recently, here is an excellent analysis done by Wayne Sheffield comparing the performance difference between Inline Table Valued functions and Multi-Statement functions.

The reason it is throwing that exception is because you have the argument rb, which opens the file in binary mode. Change that to r, which will by default open the file in text mode.

read = csv.reader(ifile)

                                                                        <RowStyle Font-Names="Calibri" ForeColor="#000000" />
                                                                    </asp:GridView>
                                                                </div>
                                                            </div>
                                                        </div>
                                                    </div>

A lot of these answers won't actually work, having tried them myself. Give this a go:

string filepath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
DirectoryInfo d = new DirectoryInfo(filepath);

foreach (var file in d.GetFiles("*.txt"))
{
      Directory.Move(file.FullName, filepath + "\\TextFiles\\" + file.Name);
}

It will move all .txt files on the desktop to the folder TextFiles.

As an exploration of this topic, I have a presentation titled "Securing TodoMVC Using the Web Cryptography API" (video, code).

It uses the Web Cryptography API to store the todo list encrypted in localStorage by password protecting the application and using a password derived key for encryption. If you forget or lose the password, there is no recovery. (Disclaimer - it was a POC and not intended for production use.)

As the other answers state, this is still susceptible to XSS or malware installed on the client computer. However, any sensitive data would also be in memory when the data is stored on the server and the application is in use. I suggest that offline support may be the compelling use case.

In the end, encrypting localStorage probably only protects the data from attackers that have read only access to the system or its backups. It adds a small amount of defense in depth for OWASP Top 10 item A6-Sensitive Data Exposure, and allows you to answer "Is any of this data stored in clear text long term?" correctly.

Don't nest <form> tags, that will not work. Just use Bootstrap classes.

Bootstrap 3

<form class="form-horizontal" role="form">
    <div class="form-group">
      <label for="inputType" class="col-md-2 control-label">Type</label>
      <div class="col-md-3">
          <input type="text" class="form-control" id="inputType" placeholder="Type">
      </div>
    </div>
    <div class="form-group">
        <span class="col-md-2 control-label">Metadata</span>
        <div class="col-md-6">
            <div class="form-group row">
                <label for="inputKey" class="col-md-1 control-label">Key</label>
                <div class="col-md-2">
                    <input type="text" class="form-control" id="inputKey" placeholder="Key">
                </div>
                <label for="inputValue" class="col-md-1 control-label">Value</label>
                <div class="col-md-2">
                    <input type="text" class="form-control" id="inputValue" placeholder="Value">
                </div>
            </div>
        </div>
    </div>
</form>

You can achieve that behaviour in many ways, that's just an example. Test it on this bootply

Bootstrap 2

<form class="form-horizontal">
    <div class="control-group">
        <label class="control-label" for="inputType">Type</label>
        <div class="controls">
            <input type="text" id="inputType" placeholder="Type">
        </div>
    </div>
    <div class="control-group">
        <span class="control-label">Metadata</span>
        <div class="controls form-inline">
            <label for="inputKey">Key</label>
            <input type="text" class="input-small" placeholder="Key" id="inputKey">
            <label for="inputValue">Value</label>
            <input type="password" class="input-small" placeholder="Value" id="inputValue">
        </div>
    </div>
</form>

Note that I'm using .form-inline to get the propper styling inside a .controls.

For MacOS;

Run on Terminal >

open ~/.bash_profile

Paste all of this=

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm

In addition to the accepted answer, it is useful to know the following ...

Each of those functions should have manual pages associated with them.

If you run man -k syslog (a keyword search of man pages) you will get a list of man pages that refer to, or are about syslog

$ man -k syslog
logger (1)           - a shell command interface to the syslog(3) system l...
rsyslog.conf (5)     - rsyslogd(8) configuration file
rsyslogd (8)         - reliable and extended syslogd
syslog (2)           - read and/or clear kernel message ring buffer; set c...
syslog (3)           - send messages to the system logger
vsyslog (3)          - send messages to the system logger

You need to understand the manual sections in order to delve further.

Here's an excerpt from the man page for man, that explains man page sections :

The table below shows the section numbers of the manual followed  by
the types of pages they contain.

   1   Executable programs or shell commands
   2   System calls (functions provided by the kernel)
   3   Library calls (functions within program libraries)
   4   Special files (usually found in /dev)
   5   File formats and conventions eg /etc/passwd
   6   Games
   7   Miscellaneous  (including  macro  packages and conven-
       tions), e.g. man(7), groff(7)
   8   System administration commands (usually only for root)
   9   Kernel routines [Non standard]

To read the above run

$man man 

So, if you run man 3 syslog you get a full manual page for the syslog function that you called in your code.

SYSLOG(3)                Linux Programmer's Manual                SYSLOG(3)

NAME
   closelog,  openlog,  syslog,  vsyslog  - send messages to the system
   logger

SYNOPSIS
   #include <syslog.h>

   void openlog(const char *ident, int option, int facility);
   void syslog(int priority, const char *format, ...);
   void closelog(void);

   #include <stdarg.h>

   void vsyslog(int priority, const char *format, va_list ap);

Not a direct answer but hopefully you will find this useful.

Ignore is exactly what the name implies.

It doesn't "throw away" something you don't need instead, it ignores the amount of characters you specify when you call it, up to the char you specify as a breakpoint.

It works with both input and output buffers.

Essentially, for std::cin statements you use ignore before you do a getline call, because when a user inputs something with std::cin, they hit enter and a '\n' char gets into the cin buffer. Then if you use getline, it gets the newline char instead of the string you want. So you do a std::cin.ignore(1000,'\n') and that should clear the buffer up to the string that you want. (The 1000 is put there to skip over a specific amount of chars before the specified break point, in this case, the \n newline character.)

Adding also Kotlin version with:

• getting text from resources (strings.xml)
• getting color from resources (colors.xml)
• "fetching HEX" moved as extension

fun getMulticolorSpanned(): Spanned {
    // Get text from resources
    val text: String = getString(R.string.your_text_from_resources)

    // Get color from resources and parse it to HEX (RGB) value
    val warningHexColor = getHexFromColors(R.color.your_error_color)

    // Use above string & color in HTML
    val html = "<string>$text<span style=\"color:#$warningHexColor;\">*</span></string>"

    // Parse HTML (base on API version)
    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        Html.fromHtml(html, Html.FROM_HTML_MODE_LEGACY)
    } else {
        Html.fromHtml(html)
    }
}

And Kotlin extension (with removing alpha):

fun Context.getHexFromColors(
    colorRes: Int
): String {
    val labelColor: Int = ContextCompat.getColor(this, colorRes)
    return String.format("%X", labelColor).substring(2)
}

I had a problem with accented characters when converting a PHP array to JSON. I put UTF-8 stuff all over the place but nothing solved my problem until I added this piece of code in my PHP while loop where I was pushing the array:

$es_words[] = array(utf8_encode("$word"),"$alpha","$audio");

It was only the '$word' variable that was giving a problem. Afterwards it did a jason_encode no problem.

Hope that helps

Use svn merge:

svn merge -c -[rev num that deleted the file] http://<path to repository>

So an example:

svn merge -c -12345 https://svn.mysite.com/svn/repo/project/trunk
             ^ The negative is important

For TortoiseSVN (I think...)

• Right click in Explorer, go to TortoiseSVN -> Merge...
• Make sure "Merge a range of revisions" is selected, click Next
• In the "Revision range to merge" textbox, specify the revision that removed the file
• Check the "Reverse merge" checkbox, click Next
• Click Merge

That is completely untested, however.

Edited by OP: This works on my version of TortoiseSVN (the old kind without the next button)

• Go to the folder that stuff was delated from
• Right click in Explorer, go to TortoiseSVN -> Merge...
• in the From section enter the revision that did the delete
• in the To section enter the revision before the delete.
• Click "merge"
• commit

The trick is to merge backwards. Kudos to sean.bright for pointing me in the right direction!

Edit: We are using different versions. The method I described worked perfectly with my version of TortoiseSVN.

Also of note is that if there were multiple changes in the commit you are reverse merging, you'll want to revert those other changes once the merge is done before you commit. If you don't, those extra changes will also be reversed.

If you're using PHP you can test your PUT upload using the code below:

#Initiate cURL object
$curl = curl_init();
#Set your URL
curl_setopt($curl, CURLOPT_URL, 'https://local.simbiat.ru');
#Indicate, that you plan to upload a file
curl_setopt($curl, CURLOPT_UPLOAD, true);
#Indicate your protocol
curl_setopt($curl, CURLOPT_PROTOCOLS, CURLPROTO_HTTPS);
#Set flags for transfer
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_BINARYTRANSFER, 1);
#Disable header (optional)
curl_setopt($curl, CURLOPT_HEADER, false);
#Set HTTP method to PUT
curl_setopt($curl, CURLOPT_PUT, 1);
#Indicate the file you want to upload
curl_setopt($curl, CURLOPT_INFILE, fopen('path_to_file', 'rb'));
#Indicate the size of the file (it does not look like this is mandatory, though)
curl_setopt($curl, CURLOPT_INFILESIZE, filesize('path_to_file'));
#Only use below option on TEST environment if you have a self-signed certificate!!! On production this can cause security issues
#curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
#Execute
curl_exec($curl);

If you can't write out the where clause manually to include the "or" statement (ie, you want to combine two scopes), you can use union:

Model.find_by_sql("#{Model.scope1.to_sql} UNION #{Model.scope2.to_sql}")

(source: ActiveRecord Query Union)

This is will return all records matching either query. However, this returns an array, not an arel. If you really want to return an arel, you checkout this gist: https://gist.github.com/j-mcnally/250eaaceef234dd8971b.

This will do the job, as long as you don't mind monkey patching rails.

You can connect to a AWS ec-2 instance using the following commands.

chmod 400 mykey.pem

ssh -i mykey.pem username@your-ip

by default the machine name usually be like ubuntu since usually ubuntu machine is used as a server so the following command will work in that case.

ssh -i mykey.pem ubuntu@your-ip

The fastest way is to do a*a or a**2 or np.square(a) whereas np.power(a, 2) showed to be considerably slower.

np.power() allows you to use different exponents for each element if instead of 2 you pass another array of exponents. From the comments of @GarethRees I just learned that this function will give you different results than a**2 or a*a, which become important in cases where you have small tolerances.

I've timed some examples using NumPy 1.9.0 MKL 64 bit, and the results are shown below:

In [29]: a = np.random.random((1000, 1000))

In [30]: timeit a*a
100 loops, best of 3: 2.78 ms per loop

In [31]: timeit a**2
100 loops, best of 3: 2.77 ms per loop

In [32]: timeit np.power(a, 2)
10 loops, best of 3: 71.3 ms per loop

You're talking about histograms, but this doesn't quite make sense. Histograms and bar charts are different things. An histogram would be a bar chart representing the sum of values per year, for example. Here, you just seem to be after bars.

Here is a complete example from your data that shows a bar of for each required value at each date:

import pylab as pl
import datetime

data = """0 14-11-2003
1 15-03-1999
12 04-12-2012
33 09-05-2007
44 16-08-1998
55 25-07-2001
76 31-12-2011
87 25-06-1993
118 16-02-1995
119 10-02-1981
145 03-05-2014"""

values = []
dates = []

for line in data.split("\n"):
    x, y = line.split()
    values.append(int(x))
    dates.append(datetime.datetime.strptime(y, "%d-%m-%Y").date())

fig = pl.figure()
ax = pl.subplot(111)
ax.bar(dates, values, width=100)
ax.xaxis_date()

You need to parse the date with strptime and set the x-axis to use dates (as described in this answer).

If you're not interested in having the x-axis show a linear time scale, but just want bars with labels, you can do this instead:

fig = pl.figure()
ax = pl.subplot(111)
ax.bar(range(len(dates)), values)

EDIT: Following comments, for all the ticks, and for them to be centred, pass the range to set_ticks (and move them by half the bar width):

fig = pl.figure()
ax = pl.subplot(111)
width=0.8
ax.bar(range(len(dates)), values, width=width)
ax.set_xticks(np.arange(len(dates)) + width/2)
ax.set_xticklabels(dates, rotation=90)

You can find the URL for your class first. If it's a JAR, then you load the manifest from there. For example,

Class clazz = MyClass.class;
String className = clazz.getSimpleName() + ".class";
String classPath = clazz.getResource(className).toString();
if (!classPath.startsWith("jar")) {
  // Class not from JAR
  return;
}
String manifestPath = classPath.substring(0, classPath.lastIndexOf("!") + 1) + 
    "/META-INF/MANIFEST.MF";
Manifest manifest = new Manifest(new URL(manifestPath).openStream());
Attributes attr = manifest.getMainAttributes();
String value = attr.getValue("Manifest-Version");

If the goal simply is to list all computer objects with an empty description attribute try this

import-module activedirectory  
$domain = "domain.example.com" 
Get-ADComputer -Filter '*' -Properties Description | where { $_.Description -eq $null }

Run As > Java Application wont show up if the class that you want to run does not contain the main method. Make sure that the class you trying to run has main defined in it.

You can do:

for f in *.txt; do (cat "${f}"; echo) >> finalfile.txt; done

Make sure the file finalfile.txt does not exist before you run the above command.

If you are allowed to use awk you can do:

awk 'FNR==1{print ""}1' *.txt > finalfile.txt

MD5 worked for me changing my database manually. See: Resetting Your Password

just add new style like this:

<style name="mySpinnerItemStyle" parent="ThemeOverlay.AppCompat.Dark">
    <item name="android:textColor">#000</item>
    <item name="android:color">#000</item>
</style>

and use it:

<Spinner
      android:id="@+id/spinnerCategories"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      style="@style/mySpinnerItemStyle"
      android:layout_margin="5dp" />

You can with a classloader and the class name, eventually some parameters.

final ClassLoader classLoader = ...
final Class<?> aClass = classLoader.loadClass("java.lang.Integer");
final Constructor<?> constructor = aClass.getConstructor(int.class);
final Object o = constructor.newInstance(123);
System.out.println("o = " + o);

That's not how ASP.NET MVC is supposed to be used. You do not redirect from views. You redirect from the corresponding controller action:

public ActionResult SomeAction()
{
    ...
    return RedirectToAction("SomeAction", "SomeController");
}

Now since I see that in your example you are attempting to redirect to the LogOn action, you don't really need to do this redirect manually, but simply decorate the controller action that requires authentication with the [Authorize] attribute:

[Authorize]
public ActionResult SomeProtectedAction()
{
    ...
}

Now when some anonymous user attempts to access this controller action, the Forms Authentication module will automatically intercept the request much before it hits the action and redirect the user to the LogOn action that you have specified in your web.config (loginUrl).

You get your browser's language for your button. There's no way to change it programmatically.

If you want to get the root directory of your yii2 project use, assuming that the name of your project is project_app you'll need to use:

echo Yii::getAlias('@app');

on windows you'd see "C:\dir\to\project_app"

on linux you'll get "/var/www/dir/to/your/project_app"

I was formally using:

echo Yii::getAlias('@webroot').'/..';

I hope this helps someone

URL-encoded payload must be provided on the body parameter of the http.NewRequest(method, urlStr string, body io.Reader) method, as a type that implements io.Reader interface.

Based on the sample code:

package main

import (
    "fmt"
    "net/http"
    "net/url"
    "strconv"
    "strings"
)

func main() {
    apiUrl := "https://api.com"
    resource := "/user/"
    data := url.Values{}
    data.Set("name", "foo")
    data.Set("surname", "bar")

    u, _ := url.ParseRequestURI(apiUrl)
    u.Path = resource
    urlStr := u.String() // "https://api.com/user/"

    client := &http.Client{}
    r, _ := http.NewRequest(http.MethodPost, urlStr, strings.NewReader(data.Encode())) // URL-encoded payload
    r.Header.Add("Authorization", "auth_token=\"XXXXXXX\"")
    r.Header.Add("Content-Type", "application/x-www-form-urlencoded")
    r.Header.Add("Content-Length", strconv.Itoa(len(data.Encode())))

    resp, _ := client.Do(r)
    fmt.Println(resp.Status)
}

resp.Status is 200 OK this way.

This was a developer mistake - a misplaced ending brace, which made the above function a nested function.

I see a lot of questions related to the undefined function error in SO. Let me note down this as an answer, in case someone else have the same issue with function scope.

Things I tried to troubleshoot first:

1. Searched for the php file with the function definition in it. Verified that the file exists.
2. Verified that the require (or include) statement for the above file exists in the page. Also, verified the absolute path in the require/include is correct.
3. Verified that the filename is spelled correctly in the require statement.
4. Echoed a word in the included file, to see if it has been properly included.
5. Defined a separate function at the end of file, and called it. It worked too.

It was difficult to trace the braces, since the functions were very long - problem with legacy systems. Further steps to troubleshoot were this:

1. I already defined a simple print function at the end of included file. I moved it to just above the "undefined function". That made it undefined too.

2. Identified this as some scope issue.

3. Used the Netbeans collapse (code fold) feature to check the function just above this one. So, the 1000 lines function above just collapsed along with this one, making this a nested function.

4. Once the problem identified, cut-pasted the function to the end of file, which solved the issue.

If you want to add a modal and a tooltip without adding javascript or altering the tooltip function, you could also simply wrap an element around it:

<span data-toggle="modal" data-target="modal">
    <a data-toggle="tooltip" data-placement="top" title="Tooltip">
      Hover Me           
    </a>
</span>

you can do this :

private void setRowNumber(DataGridView dgv)
{
    foreach (DataGridViewRow row in dgv.Rows)
    {
        row.HeaderCell.Value = row.Index + 1;
    }

    dgv.AutoResizeRowHeadersWidth(DataGridViewRowHeadersWidthSizeMode.AutoSizeToAllHeaders);

}

Items should have an "ID" field, and Tags should have an "ID" field (Primary Key, Clustered).

Then make an intermediate table of ItemID/TagID and put the "Perfect Index" on there.

Here's an example of a transaction that will rollback on error and return the error code.

DELIMITER $$

The installation of CuDNN is just copying some files. Hence to check if CuDNN is installed (and which version you have), you only need to check those files.

Install CuDNN

Step 1: Register an nvidia developer account and download cudnn here (about 80 MB). You might need nvcc --version to get your cuda version.

Step 2: Check where your cuda installation is. For most people, it will be /usr/local/cuda/. You can check it with which nvcc.

Step 3: Copy the files:

$ cd folder/extracted/contents
$ sudo cp include/cudnn.h /usr/local/cuda/include
$ sudo cp lib64/libcudnn* /usr/local/cuda/lib64
$ sudo chmod a+r /usr/local/cuda/lib64/libcudnn*

Check version

You might have to adjust the path. See step 2 of the installation.

$ cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2

Notes

When you get an error like

F tensorflow/stream_executor/cuda/cuda_dnn.cc:427] could not set cudnn filter descriptor: CUDNN_STATUS_BAD_PARAM

with TensorFlow, you might consider using CuDNN v4 instead of v5.

GSON has a builder that takes a Reader object: fromJson(Reader json, Class classOfT).

This means you can create a Reader from a URL and then pass it to Gson to consume the stream and do the deserialisation.

Only three lines of relevant code.

import java.io.InputStreamReader;
import java.net.URL;
import java.util.Map;

import com.google.gson.Gson;

public class GsonFetchNetworkJson {

    public static void main(String[] ignored) throws Exception {

        URL url = new URL("https://httpbin.org/get?color=red&shape=oval");
        InputStreamReader reader = new InputStreamReader(url.openStream());
        MyDto dto = new Gson().fromJson(reader, MyDto.class);

        // using the deserialized object
        System.out.println(dto.headers);
        System.out.println(dto.args);
        System.out.println(dto.origin);
        System.out.println(dto.url);
    }

    private class MyDto {
        Map<String, String> headers;
        Map<String, String> args;
        String origin;
        String url;

^{If you happen to get a 403 error code with an endpoint which otherwise works fine (e.g. with curl or other clients) then a possible cause could be that the endpoint expects a User-Agent header and by default Java URLConnection is not setting it. An easy fix is to add at the top of the file e.g. System.setProperty("http.agent", "Netscape 1.0");.}

Actually the coded modules and the Global.asax examples shown above only work for valid requests.

For example, add < on the end of your URL and you will get a "Bad request" page which still exposes the server header. A lot of developers overlook this.

The registry settings shown do not work either. URLScan is the ONLY way to remove the "server" header (at least in IIS 7.5).

Check that all your bundle resources are copied in build phase.

Example:

$number = 4;
print "You have the {$number}th edition book";
//output: "You have the 4th edition book";

Without curly braces PHP would try to find a variable named $numberth, that doesn't exist!

WinSCP has the command line functionality:

c:\>winscp.exe /console /script=example.txt

where scripting is done in example.txt.

See http://winscp.net/eng/docs/guide_automation

Refer to http://winscp.net/eng/docs/guide_automation_advanced for details on how to use a scripting language such as Windows command interpreter/php/perl.

FileZilla does have a command line but it is limited to only opening the GUI with a pre-defined server that is in the Site Manager.

In netbeans, you can right click the mouse and then save as a .txt file. Then, based on the created .txt file, you can convert to the file in any format you want to get.

This piece of code:

for s in ("fukushima", "123 is a number", ""):
    print s.ljust(20),  s[0].isdigit() if s else False

prints out the following:

fukushima            False
123 is a number      True
                     False

The following (evil) code runs more than TWICE as fast as the nmap method

for i in {1..254} ;do (ping 192.168.1.$i -c 1 -w 5  >/dev/null && echo "192.168.1.$i" &) ;done

takes around 10 seconds, where the standard nmap

nmap -sP 192.168.1.1-254

takes 25 seconds...

I had the same issue today. The file I was trying to load into my code was open for editing in Excel. After closing Excel, the code began to work!

Try this in your css:

.card-img-top {
    width: 100%;
    height: 15vw;
    object-fit: cover;
}

Adjust the height vw as you see fit. The object-fit: cover enables zoom instead of image stretching.

Unless ADB is running as root (as it would on an emulator) you cannot generally view anything under /data unless an application which owns it has made it world readable. Further, you cannot browse the directory structure - you can only list files once you get to a directory where you have access, by explicitly entering its path.

Broadly speaking you have five options:

• Do the investigation within the owning app

• Mark the files in question as public, and use something (adb shell or adb pull) where you can enter a full path name, instead of trying to browse the tree

• Have the owning app copy the entire directory to the SD card

• Use an emulator or rooted device where adb (and thus the ddms browser's access) can run as root (or use a root file explorer or a rooted device)

• use adb and the run-as tool with a debuggable apk to get a command line shell running as the app's user id. For those familiar with the unix command line, this can be the most effective (though the toolbox sh on android is limited, and uses its tiny vocabulary of error messages in misleading ways)

Further to the above excellent comments about trusted constraints:

select * from sys.foreign_keys where is_not_trusted = 1 ;
select * from sys.check_constraints where is_not_trusted = 1 ;

An untrusted constraint, much as its name suggests, cannot be trusted to accurately represent the state of the data in the table right now. It can, however, but can be trusted to check data added and modified in the future.

Additionally, untrusted constraints are disregarded by the query optimiser.

The code to enable check constraints and foreign key constraints is pretty bad, with three meanings of the word "check".

ALTER TABLE [Production].[ProductCostHistory] 
WITH CHECK -- This means "Check the existing data in the table".
CHECK CONSTRAINT -- This means "enable the check or foreign key constraint".
[FK_ProductCostHistory_Product_ProductID] -- The name of the check or foreign key constraint, or "ALL".

We need to remember that the {% endif %} comes after the {% else %}.

So this is an example:

{% if someTest %}
     <p> Something is True </p>
{% else %}
     <p> Something is False </p>
{% endif %}

    });
});

It depends on the Markdown rendering engine and the Markdown flavour. There is no standard for this. If you mean GitHub flavoured Markdown for example, shell should work fine. Aliases are sh, bash or zsh. You can find the list of available syntax lexers here.

By default flush mode is AUTO which means that: "The Session is sometimes flushed before query execution in order to ensure that queries never return stale state", but most of the time session is flushed when you commit your changes. Manual calling of the flush method is usefull when you use FlushMode=MANUAL or you want to do some kind of optimization. But I have never done this so I can't give you practical advice.

I tried all of that things and it doesn't worked for me.

I Just installed SAPCrystalReport in my computer and it's working now.

Just use axes.get_ylim(), it is very similar to set_ylim. From the docs:

get_ylim()

Get the y-axis range [bottom, top]

SerialPort (RS-232 Serial COM Port) in C# .NET
This article explains how to use the SerialPort class in .NET to read and write data, determine what serial ports are available on your machine, and how to send files. It even covers the pin assignments on the port itself.

Example Code:

using System;
using System.IO.Ports;
using System.Windows.Forms;

namespace SerialPortExample
{
  class SerialPortProgram
  {
    // Create the serial port with basic settings
    private SerialPort port = new SerialPort("COM1",
      9600, Parity.None, 8, StopBits.One);

    [STAThread]
    static void Main(string[] args)
    { 
      // Instatiate this class
      new SerialPortProgram();
    }

    private SerialPortProgram()
    {
      Console.WriteLine("Incoming Data:");

      // Attach a method to be called when there
      // is data waiting in the port's buffer
      port.DataReceived += new 
        SerialDataReceivedEventHandler(port_DataReceived);

      // Begin communications
      port.Open();

      // Enter an application loop to keep this thread alive
      Application.Run();
    }

    private void port_DataReceived(object sender,
      SerialDataReceivedEventArgs e)
    {
      // Show all the incoming data in the port's buffer
      Console.WriteLine(port.ReadExisting());
    }
  }
}

To read:-

NSString *html = [myWebView stringByEvaluatingJavaScriptFromString: @"document.getElementById('your div id').textContent"];
NSLog(html);    

To modify:-

html = [myWebView stringByEvaluatingJavaScriptFromString: @"document.getElementById('your div id').textContent=''"];

A simple solution is:

if (newStr4.startsWith("Mon") || newStr4.startsWith("Tue") || newStr4.startsWith("Wed"))
// ... you get the idea ...

A fancier solution would be:

List<String> days = Arrays.asList("SUN", "MON", "TUE", "WED", "THU", "FRI", "SAT");
String day = newStr4.substring(0, 3).toUpperCase();
if (days.contains(day)) {
    // ...
}

Try this:

a = 1
b = 2
int_div  = a // b

It's already a string? Remove the getText() call.

int myNum = 0;

try {
    myNum = Integer.parseInt(myString);
} catch(NumberFormatException nfe) {
  // Handle parse error.
}

For those who just need to join one level below at the top.

Being clearer, how transform this:

Array
    (
        [0] => Array
            (
                [0] => Array
                    (
                        [id] => 001
                    )
                [1] => Array
                    (
                        [id] => 005
                    )
            )
        [1] => Array
            (
                [0] => Array
                    (
                        [id] => 007
                    )
                [1] => Array
                    (
                        [id] => 009
                    )
            )
    )

On this:

Array
    (
        [0] => Array
            (
                [0] => Array
                    (
                        [id] => 001
                    )
                [1] => Array
                    (
                        [id] => 005
                    )
                [2] => Array
                    (
                        [id] => 007
                    )
                [3] => Array
                    (
                        [id] => 009
                    )
            )
    )

The (simple) code:

foreach ($multi_array as $key => $reduced_array) {
    foreach ($reduced_array as $key => $value) {
        $new_array[] = $value;
    }
}

With so many functions available, sometimes we forget that we can do something with a simple code ...

Using replace() with regular expressions is the most flexible/powerful. It's also the only way to globally replace every instance of a search pattern in JavaScript. The non-regex variant of replace() will only replace the first instance.

For example:

var str = "foo gar gaz";

// returns: "foo bar gaz"
str.replace('g', 'b');

// returns: "foo bar baz"
str = str.replace(/g/gi, 'b');

In the latter example, the trailing /gi indicates case-insensitivity and global replacement (meaning that not just the first instance should be replaced), which is what you typically want when you're replacing in strings.

To remove characters, use an empty string as the replacement:

var str = "foo bar baz";

// returns: "foo r z"
str.replace(/ba/gi, '');

If you want to delete everything from folder (including subfolders) use this combination of array_map, unlink and glob:

array_map( 'unlink', array_filter((array) glob("path/to/temp/*") ) );

This call can also handle empty directories ( thanks for the tip, @mojuba!)

This is the method I used to disable.Hope it helps.

$("#ThisLink").attr("href","javascript:;");

Here is a full example of setting up Guava Cache in Spring. I used Guava over Ehcache because it's a bit lighter weight and the config seemed more straight forward to me.

Import Maven Dependencies

Add these dependencies to your maven pom file and run clean and packages. These files are the Guava dep and Spring helper methods for use in the CacheBuilder.

    <dependency>
        <groupId>com.google.guava</groupId>
        <artifactId>guava</artifactId>
        <version>18.0</version>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context-support</artifactId>
        <version>4.1.7.RELEASE</version>
    </dependency>

Configure the Cache

You need to create a CacheConfig file to configure the cache using Java config.

@Configuration
@EnableCaching
public class CacheConfig {

   public final static String CACHE_ONE = "cacheOne";
   public final static String CACHE_TWO = "cacheTwo";

   @Bean
   public Cache cacheOne() {
      return new GuavaCache(CACHE_ONE, CacheBuilder.newBuilder()
            .expireAfterWrite(60, TimeUnit.MINUTES)
            .build());
   }

   @Bean
   public Cache cacheTwo() {
      return new GuavaCache(CACHE_TWO, CacheBuilder.newBuilder()
            .expireAfterWrite(60, TimeUnit.SECONDS)
            .build());
   }
}

Annotate the method to be cached

Add the @Cacheable annotation and pass in the cache name.

@Service
public class CachedService extends WebServiceGatewaySupport implements CachedService {

    @Inject
    private RestTemplate restTemplate;


    @Cacheable(CacheConfig.CACHE_ONE)
    public String getCached() {

        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);

        HttpEntity<String> reqEntity = new HttpEntity<>("url", headers);

        ResponseEntity<String> response;

        String url = "url";
        response = restTemplate.exchange(
                url,
                HttpMethod.GET, reqEntity, String.class);

        return response.getBody();
    }
}

You can see a more complete example here with annotated screenshots: Guava Cache in Spring

You can learn some tutorials for JSP page direct access database (mysql) here

Notes:

• import sql tag library in jsp page

  <%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%>

• then set datasource on page

  <sql:setDataSource var="ds" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://<yourhost>/<yourdb>" user="<user>" password="<password>"/>
  

• Now query what you want on page

  <sql:query dataSource="${ds}" var="result"> //ref  defined 'ds'
      SELECT * from <your-table>;
  </sql:query>
  

• Finally you can populate dropdowns on page using c:forEach tag to iterate result rows in select element

  <c:forEach var="row" items="${result.rows}"> //ref set var 'result' <option value='<c:out value="${row.key}"/>'><c:out value="${row.value}"/</option> </c:forEach>

All you need to give the name attribute to the each button. And you need to address each button press from the PHP script. But be careful to give each button a unique name. Because the PHP script only take care of the name most of the time

<input type="submit" name="Submit_this" id="This" />

Since spaces are used to separate command line arguments, they have to be escaped from the shell. This can be done with either a backslash () or quotes:

"/path/with/spaces in it/to/a/file"
somecommand -spaced\ option
somecommand "-spaced option"
somecommand '-spaced option'

This is assuming you're running from a shell. If you're writing code, you can usually pass the arguments directly, avoiding the problem:

Example in perl. Instead of doing:

print("code sample");system("somecommand -spaced option");

you can do

print("code sample");system("somecommand", "-spaced option");

Since when you pass the system() call a list, it doesn't break arguments on spaces like it does with a single argument call.

Using <meta http-equiv="X-UA-Compatible" content="IE=9">, IE9+ does support addEventListener by removing the "on" in the event name, like this:

 var btn1 = document.getElementById('btn1');
 btn1.addEventListener('mousedown', function() {
   console.log('mousedown');
 });

Isn't it smoother to make a method to be called after the creation of the EditText unit in an AlertDialog, for general use?

public static void EditTextListPicker(final Activity activity, final EditText EditTextItem, final String SelectTitle, final String[] SelectList) {
    EditTextItem.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
            AlertDialog.Builder builder = new AlertDialog.Builder(activity);
            builder.setTitle(SelectTitle);
            builder.setItems(SelectList, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialogInterface, int item) {
                    EditTextItem.setText(SelectList[item]);
                }
            });
            builder.create().show();
            return false;
        }
    });
}

Just use the function below that returns width and height of the screen size as an array of integers

private int[] getScreenSIze(){
        DisplayMetrics displaymetrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
        int h = displaymetrics.heightPixels;
        int w = displaymetrics.widthPixels;

        int[] size={w,h};
        return size;

    }

On your onCreate function or button click add the following code to output the screen sizes as shown below

 int[] screenSize= getScreenSIze();
        int width=screenSize[0];
        int height=screenSize[1];
        screenSizes.setText("Phone Screen sizes \n\n  width = "+width+" \n Height = "+height);

If linked server name is IP address following code is true:

select * from [1.2.3.4,1433\MSSQLSERVER].test.dbo.Table1

It's just, note [] around IP address section.

As I understand it a table has a set K of keys and a typing function T with domain K. A row, or "tuple", of the table is a function r with domain K such that r(k) is an element of T(k) for each key k. So the terminology is misleading in that a "tuple" is really more like an associative array.

Set<T> b = new HashSet<>(Arrays.asList(requiredArray));

Perhaps this will help you out - I've done something similar using jquery, except I'm loading up an unknown number of ckeditor objects. It took my a while to stumble onto this - it's not clear in the documentation.

function loadEditors() {
    var $editors = $("textarea.ckeditor");
    if ($editors.length) {
        $editors.each(function() {
            var editorID = $(this).attr("id");
            var instance = CKEDITOR.instances[editorID];
            if (instance) { instance.destroy(true); }
            CKEDITOR.replace(editorID);
        });
    }
}

And here is what I run to get the content from the editors:

    var $editors = $("textarea.ckeditor");
    if ($editors.length) {
        $editors.each(function() {
            var instance = CKEDITOR.instances[$(this).attr("id")];
            if (instance) { $(this).val(instance.getData()); }
        });
    }

UPDATE: I've changed my answer to use the correct method - which is .destroy(). .remove() is meant to be internal, and was improperly documented at one point.

You cannot change the color of colorPrimary, but you can change the theme of your application by adding a new style with a different colorPrimary color

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
</style>

<style name="AppTheme.NewTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorOne</item>
    <item name="colorPrimaryDark">@color/colorOneDark</item>
</style>

and inside the activity set theme

 setTheme(R.style.AppTheme_NewTheme);
 setContentView(R.layout.activity_main);

Note that this answer applies to python versions prior to python3.7. CPython 3.6 maintains insertion order under most circumstances as an implementation detail. Starting from Python3.7 onward, it has been declared that implementations MUST maintain insertion order to be compliant.

python dictionaries are unordered. If you want an ordered dictionary, try collections.OrderedDict.

Note that OrderedDict was introduced into the standard library in python 2.7. If you have an older version of python, you can find recipes for ordered dictionaries on ActiveState.

I simply closed all pages of visual studio and reopened ..it worked.

Additional description for John Smith's answer from the official documentation. To understand why it is.

Main host goes away

If you are adding virtual hosts to an existing web server, you must also create a block for the existing host. The ServerName and DocumentRoot included in this virtual host should be the same as the global ServerName and DocumentRoot. List this virtual host first in the configuration file so that it will act as the default host.

For example, to work properly with XAMPP, to prevent VirtualHost overriding the main host, add the follow lines into file httpd-vhosts.conf:

# Main host
<VirtualHost *:80>
    ServerName localhost
    DocumentRoot "/xampp/htdocs"
</VirtualHost>

# Additional host
<VirtualHost *:80>
    # Over directives there
</VirtualHost>

There's an explanation and solution for this on MSDN:

The function strcpy is considered unsafe due to the fact that there is no bounds checking and can lead to buffer overflow.

Consequently, as it suggests in the error description, you can use strcpy_s instead of strcpy:

strcpy_s( char *strDestination, size_t numberOfElements,
const char *strSource );

and:

None of this worked, what worked for me is scaling image down.

So depending on what size you want the image or what resoultion your image is, you can do something like this:

.ok {
      transform: perspective(100px) rotateY(0deg) scale(0.5);
      transition: transform 1s;
      object-fit:contain;
}
.ok:hover{
      transform: perspective(100px) rotateY(-10deg) scale(0.5);
}

/* Demo Preview Stuff */
.bad {
   max-width: 320px;
   object-fit:contain;
   transform: perspective(100px) rotateY(0deg);
   transition: transform 1s;
}
.bad:hover{
      transform: perspective(100px) rotateY(-10deg);
}

div {
     text-align: center;
     position: relative;
     display: flex;
}
h3{
    position: absolute;
    bottom: 30px;
    left: 0;
    right: 0;
}
     
.b {
    display: flex;
}

     border-left:1px solid #38546d; 
     border-right:1px solid #16222c; 
     height:80px;
     position:absolute;
     right:249px;
     top:10px; 
}

<div class="headerDivider"></div>

Another solution: go through a filter with your inverted conditions : Example :

if(subscribtion.isOnce() && subscribtion.isCalled()){
                continue;
}

can be replaced with

.filter(s -> !(s.isOnce() && s.isCalled()))

The most straightforward approach seem to be using "return;" though.

I faced with the problem like this.

The problem was that I added the public key without '-----BEGIN PUBLIC KEY-----' at the beginning and without '-----END PUBLIC KEY-----'.

So it causes the error.

Initially, my public key was like this:

-----BEGIN PUBLIC KEY-----
WnsbGUXbb0GbJSCwCBAhrzT0s2KMRyqqS7QBiIG7t3H2Qtmde6UoUIcTTPJgv71
......
oNLcaK2wKKyRdcROK7ZTSCSMsJpAFOY
-----END PUBLIC KEY-----

But I used just this part:

WnsbGUXb+b0GbJSCwCBAhrzT0s2KMRyqqS7QBiIG7t3H2Qtmde6UoUIcTTPJgv71
......
oNLcaK2w+KKyRdcROK7ZTSCSMsJpAFOY

You're after the zip function.

Taken directly from the question: How to merge lists into a list of tuples in Python?

>>> list_a = [1, 2, 3, 4]
>>> list_b = [5, 6, 7, 8]
>>> zip(list_a,list_b)
[(1, 5), (2, 6), (3, 7), (4, 8)]

You can simply append the row to the end of the DataFrame, and then adjust the index.

For instance:

df = df.append(pd.DataFrame([[2,3,4]],columns=df.columns),ignore_index=True)
df.index = (df.index + 1) % len(df)
df = df.sort_index()

Or use concat as:

df = pd.concat([pd.DataFrame([[1,2,3,4,5,6]],columns=df.columns),df],ignore_index=True)

Depending on your URL scheme, you can make the UTF-8 encoded part "not important". For example, if you look at Stack Overflow URLs, they're of the following form:

http://stackoverflow.com/questions/2742852/unicode-characters-in-urls

However, the server doesn't actually care if you get the part after the identifier wrong, so this also works:

http://stackoverflow.com/questions/2742852/?????????????????

So if you had a layout like this, then you could potentially use UTF-8 in the part after the identifier and it wouldn't really matter if it got garbled. Of course this probably only works in somewhat specialised circumstances...

Here's a neat little workaround:

You can use a Greek Lower Numeral Sign instead (U+0375)

It looks like this ?

Using this method saves you a lot of resources too...

The problem is that thread_obj.start() returns immediately. The child thread that you spawned executes in its own context, with its own stack. Any exception that occurs there is in the context of the child thread, and it is in its own stack. One way I can think of right now to communicate this information to the parent thread is by using some sort of message passing, so you might look into that.

Try this on for size:

import sys
import threading
import Queue


class ExcThread(threading.Thread):

    def __init__(self, bucket):
        threading.Thread.__init__(self)
        self.bucket = bucket

    def run(self):
        try:
            raise Exception('An error occured here.')
        except Exception:
            self.bucket.put(sys.exc_info())


def main():
    bucket = Queue.Queue()
    thread_obj = ExcThread(bucket)
    thread_obj.start()

    while True:
        try:
            exc = bucket.get(block=False)
        except Queue.Empty:
            pass
        else:
            exc_type, exc_obj, exc_trace = exc
            # deal with the exception
            print exc_type, exc_obj
            print exc_trace

        thread_obj.join(0.1)
        if thread_obj.isAlive():
            continue
        else:
            break


if __name__ == '__main__':
    main()

To add a gradient layer on your view

• Bind your view outlet

  @IBOutlet var YOURVIEW : UIView!
  

• Define the CAGradientLayer()

  var gradient = CAGradientLayer()
  

• Here is the code you have to write in your viewDidLoad

  YOURVIEW.layoutIfNeeded()

  gradient.startPoint = CGPoint(x: CGFloat(0), y: CGFloat(1)) gradient.endPoint = CGPoint(x: CGFloat(1), y: CGFloat(0)) gradient.frame = YOURVIEW.bounds gradient.colors = [UIColor.red.cgColor, UIColor.green.cgColor] gradient.colors = [ UIColor(red: 255.0/255.0, green: 56.0/255.0, blue: 224.0/255.0, alpha: 1.0).cgColor,UIColor(red: 86.0/255.0, green: 13.0/255.0, blue: 232.0/255.0, alpha: 1.0).cgColor,UIColor(red: 16.0/255.0, green: 173.0/255.0, blue: 245.0/255.0, alpha: 1.0).cgColor] gradient.locations = [0.0 ,0.6 ,1.0] YOURVIEW.layer.insertSublayer(gradient, at: 0)

From your code, it looks like provider is a variant or some other variable, and not an object.

Is Nothing is for objects only, yet later you say it's a value that should either be NULL or NOT NULL, which would be handled by IsNull.

Try using:

If Not IsNull(provider) Then 
    url = url & "&provider=" & provider 
End if

Alternately, if that doesn't work, try:

If provider <> "" Then 
    url = url & "&provider=" & provider 
End if

Simple:

    dim input as string = "SPQR"
    dim format as string =""
    dim result as string = ""

    'pad left:
    format = "{0,-8}"
    result = String.Format(format,input)
    'result = "SPQR    "

    'pad right
    format = "{0,8}"
    result = String.Format(format,input)
    'result = "    SPQR"

Try (in your <head> section, or existing css definitions)...

<style>
  body {
   margin:0;
   padding:0;
  }
</style>

Here's a very nice Gist that covers all the possible cases: https://gist.github.com/nepsilon/156387acf9e1e72d48fa35c4fabef0b4

Overview:

git rebase -i HEAD~X
# X is the number of commits to go back
# Move to the line of your commit, change pick into edit,
# then change your commit message:
git commit --amend
# Finish the rebase with:
git rebase --continue

Like the other answer says, in the left hand side select Products and add product. Then select Facbook Login.

I then added http://localhost:3000/ to the field 'Valid OAuth redirect URIs', and then everything worked.

Both attributes are needed and also recheck all the form elements has "name" attribute. if you are using form submit concept, other wise just use div tag instead of form element.

<input [(ngModel)]="firstname" name="something">

Its not possible as you are expecting. But you can do something like this. Pass the your java script value to the servlet/controller, do your processing and then pass this value to the jsp page by putting it into some object's as your requirement. Then you can use this value as you want.

You can use arraylistname.clone()

This is not the correct usage of the System.Threading.Timer. When you instantiate the Timer, you should almost always do the following:

_timer = new Timer( Callback, null, TIME_INTERVAL_IN_MILLISECONDS, Timeout.Infinite );

This will instruct the timer to tick only once when the interval has elapsed. Then in your Callback function you Change the timer once the work has completed, not before. Example:

private void Callback( Object state )
{
    // Long running operation
   _timer.Change( TIME_INTERVAL_IN_MILLISECONDS, Timeout.Infinite );
}

Thus there is no need for locking mechanisms because there is no concurrency. The timer will fire the next callback after the next interval has elapsed + the time of the long running operation.

If you need to run your timer at exactly N milliseconds, then I suggest you measure the time of the long running operation using Stopwatch and then call the Change method appropriately:

private void Callback( Object state )
{
   Stopwatch watch = new Stopwatch();

   watch.Start();
   // Long running operation

   _timer.Change( Math.Max( 0, TIME_INTERVAL_IN_MILLISECONDS - watch.ElapsedMilliseconds ), Timeout.Infinite );
}

I strongly encourage anyone doing .NET and is using the CLR who hasn't read Jeffrey Richter's book - CLR via C#, to read is as soon as possible. Timers and thread pools are explained in great details there.

I also had this issue because I had another console window open that was running the app and I was attempting to re-run yarn start in another console window.

The first yarn executing prevented the second from writing. So I just killed the first process and it worked

For anyone that has this issue in the future, for me it was caused by an arrow function instead of a function literal in a run block:

// bad
module('a').run(() => ...)

// good
module('a').run(function() {...})

The second option didn't work for me because the .Text element was out of scope (C# 4.0 VS2008). This was my solution...

string test = null;
foreach (ComboBoxItem item in e.AddedItems)
{
   test = item.Content.ToString();
   break;
}

I know this is a bit of an old thread but with pandas 19.02, you can do:

df.select_dtypes(include=['float64']).apply(your_function)
df.select_dtypes(exclude=['string','object']).apply(your_other_function)

http://pandas.pydata.org/pandas-docs/version/0.19.2/generated/pandas.DataFrame.select_dtypes.html

numpy.dot(a, b, out=None)

Dot product of two arrays.

For N dimensions it is a sum product over the last axis of a and the second-to-last of b.

Anaconda or Miniconda?

Choose Anaconda if you:

1. Are new to conda or Python.

2. Like the convenience of having Python and over 1,500 scientific packages automatically installed at once.

3. Have the time and disk space---a few minutes and 3 GB.

4. Do not want to individually install each of the packages you want to use.

Choose Miniconda if you:

1. Do not mind installing each of the packages you want to use individually.

2. Do not have time or disk space to install over 1,500 packages at once.

3. Want fast access to Python and the conda commands and you wish to sort out the other programs later.

What do you consider "special" characters, just simple punctuation? You should be able to use the Replace function: Replace("p.k","."," ").

Sub Test()
Dim myString as String
Dim newString as String

myString = "p.k"

newString = replace(myString, ".", " ")

MsgBox newString

End Sub

If you have several characters, you can do this in a custom function or a simple chained series of Replace functions, etc.

  Sub Test()
Dim myString as String
Dim newString as String

myString = "!p.k"

newString = Replace(Replace(myString, ".", " "), "!", " ")

'## OR, if it is easier for you to interpret, you can do two sequential statements:
'newString = replace(myString, ".", " ")
'newString = replace(newString, "!", " ")

MsgBox newString

End Sub

If you have a lot of potential special characters (non-English accented ascii for example?) you can do a custom function or iteration over an array.

Const SpecialCharacters As String = "!,@,#,$,%,^,&,*,(,),{,[,],},?"  'modify as needed
Sub test()
Dim myString as String
Dim newString as String
Dim char as Variant
myString = "!p#*@)k{kdfhouef3829J"
newString = myString
For each char in Split(SpecialCharacters, ",")
    newString = Replace(newString, char, " ")
Next
End Sub

VERY EASY:

just use this to replace all white spaces with -:

myString.replace(/ /g,"-")

Yes you can. I assume you have a xampp already installed. So,

• Close all xampp instances. Using task manager stop apache and mysqld.
• Then rename the xampp to xampp1 or something after xampp name.
• Now Download the other xampp version. Create a folder name xampp only. Install the downloaded xampp there.
• Now depending on the xampp version of your requirement, just rename the target folder to xampp only and other folder to different name.

That's how I am working with multiple xampp installed

Use FindIndex and lambda to find and replace your values:

int j = listofelements.FindIndex(i => i.Contains(valueFieldValue.ToString())); //Finds the item index

lstString[j] = lstString[j].Replace(valueFieldValue.ToString(), value.ToString()); //Replaces the item by new value

If you throw the exception, the method execution will stop and the exception is thrown to the caller method. throw always interrupt the execution flow of the current method. a try/catch block is something you could write when you call a method that may throw an exception, but throwing an exception just means that method execution is terminated due to an abnormal condition, and the exception notifies the caller method of that condition.

Find this tutorial about exception and how they work - http://docs.oracle.com/javase/tutorial/essential/exceptions/

I had this problem in a Backbone project: my view contains a input and is re-rendered. Here is what happens (example for a checkbox):

• The first render occurs;
• jquery.validate is applied, adding an event onClick on the input;
• View re-renders, the original input disappears but jquery.validate is still bound to it.

The solution is to update the input rather than re-render it completely. Here is an idea of the implementation:

var MyView = Backbone.View.extend({
    render: function(){
        if(this.rendered){
            this.update();
            return;
        }
        this.rendered = true;

        this.$el.html(tpl(this.model.toJSON()));
        return this;
    },
    update: function(){
        this.$el.find('input[type="checkbox"]').prop('checked', this.model.get('checked'));
        return this;
    }
});

This way you don't have to change any existing code calling render(), simply make sure update() keeps your HTML in sync and you're good to go.
